Description

Intelligent sample preparation system for coal samples

Technical Field

The invention relates to the field of coal sample preparation equipment, in particular to an intelligent coal sample preparation system.

Background

For coal quality analysis, it is actually a sampling analysis process. Coal is a non-uniform substance (particle size, mass characteristic distribution, etc.), the sampled female parent is generally larger (tens to tens of thousands of tons are different), the process of pumping a representative sample representing the mass and characteristic of the whole female parent to the maximum extent is called sampling, and at present, various methods such as mechanical sampling, manual sampling, semi-mechanical sampling, etc. are available. There are mandatory standards in each country, and sampling work must be performed in compliance with the standards.

After the sample is collected according to the standard, the next process is sample preparation, and the criterion of the sample preparation process is that the granularity of the sample is gradually reduced and the quality is gradually reduced on the premise of not damaging the representativeness of the sample until the granularity and the quality (weight) requirements of laboratory tests on the sample are met. The sample preparation process generally comprises the processes of air drying, crushing, dividing, grinding and the like. The air drying (or heat drying, but the temperature should be less than 50 ℃) process is to reduce the moisture outside the sample, so as to facilitate the subsequent crushing and shrinking process to be carried out normally. Crushing during sample preparation is the process of reducing the particle size of the sample. The shrinkage process is a representative quality reduction process for the sample, the reduced sample must represent the coal quality characteristics of the sample before reduction, the shrinkage process is a process for reducing the sample amount in the sample preparation process, and the standard regulation in other processes should not allow coal sample loss. Because the sample loss (such as coal dust loss, gangue being selected, etc.) of the non-shrinkage process changes the coal quality characteristics of the sample, selectively (not necessarily artificially) losing the sample is absolutely impermissible in the sample preparation process.

At present, coal samples are mainly manufactured into three types according to national standards: all water samples, stock samples and analysis samples are different in granularity, water content and the like, and the amounts to be provided are different, for example, all water samples with granularity of 13mm need to be provided with not less than 1.25 kg, stock samples with granularity of 3mm need to be provided with not less than 0.7 kg, and analysis samples with granularity of 0.2mm need to be provided with not less than 60 g. When different coal samples are manufactured, in order to ensure the reliability of the samples, the different coal samples are respectively packaged by using a sample packaging device for later sample analysis.

In order to realize sample preparation automation, each independent module (equipment) for sample preparation needs to be combined and matched with each other, so that flexible conveying of materials or samples in each module (equipment) can be realized, and three different samples (full water sample, stock sample and analysis sample) can be prepared simultaneously. The prior art mainly has the following problems:

(1) The degree of automation of the transportation is not high. The transfer of coal from the sampling end to the sample end usually requires manual handling (manual handling to the sample end, or manual handling of the sample to the conveyor to the sample end, or manual unloading from the conveyor), which results in high labor intensity and low working efficiency. Especially when the transfer path is long and the transfer can not be carried out by using the traditional conveying equipment such as a conveying belt, the rapid and large-batch centralized conveying can not be satisfied. So that the operation requirements of unattended operation and automatic butt joint in a sampling and sample preparing system cannot be met.

(2) The intelligent degree of sample preparation is not high, the sample preparation is efficient and the security is poor. The manual mode is adopted to prepare samples step by step, materials are manually transferred from a previous stage sample preparation module (equipment) to a next stage sample preparation unit (equipment), automation cannot be embodied completely, labor intensity is high, efficiency is low, and the phenomenon of fake making easily exists due to manual intervention in each link.

(4) The traditional belt conveying step-by-step sample preparation is adopted, the mode is that materials are transferred from the lower output port of the upper sample preparation module (equipment) to the upper input port of the lower sample preparation unit (equipment), the length of the conveying belt is required to be prolonged to reduce the lifting gradient, and the occupied area of the whole sample preparation system is required to be large, and the space utilization rate is not high. Adopting a multi-bucket conveying mode to prepare samples step by step, firstly, dispersing and flatly conveying the coal samples, wherein the surface area of the coal samples exposed in the air is larger, the water loss is more, and the subsequent analysis and test precision is affected; secondly, the contact area between the coal sample and the bucket wall in the conveying mode is larger, so that the residual of the coal sample in the bucket is more, the next sample preparation is polluted, and the subsequent analysis and test precision is affected; and thirdly, when the multi-bucket conveyor is actually used, only a small part of the buckets are filled with coal samples during each conveying, and the actual use efficiency of all equipment is low. Fourth, whether adopting the belt conveying or the multi-bucket conveying mode, in order to install the conveying equipment, the problem of large occupied area exists among a plurality of sample preparation modules (equipment).

(5) The existing sample collecting and preparing system has low automation degree, most sampled coal samples are conveyed and manually batched by manual sample mixing, the labor intensity is high, the working efficiency is low, the automation degree is low, and the operation requirement of full-automatic operation in the sample collecting and preparing system can not be met. Meanwhile, the sample collection and batch collection are needed to be carried out manually. The risk that the sample is scattered due to the fact that the sample bucket falls down when the sample is manually replaced is caused, and the safety is poor.

(6) Part of the existing sample collecting and preparing system has low intelligent degree, does not have a buffer function, can only process sample mixing and batching operations with less sample batches and less sample quantity of each batch, and cannot meet the requirement of the existing sample collecting and preparing system when the batches of samples are more and the sample quantity of each batch is very large, and cannot process the sample mixing and batching operations with multiple batches and multiple quantities. For example, unified automation operations of sample preparation and batching for multiple batches, empty bucket batching for multiple batches, and sample preparation and batching for multiple batches after each other cannot be completed simultaneously.

(7) Part of the existing sample collecting and preparing system is huge in size and large in occupied area, is not suitable for being flexibly placed and used in industrialization, and especially if multiple batches of sample collecting and preparing operations are to be realized, the system is inevitably huge and complex in size in order to meet annular collecting and preparing circulation.

It should be noted that, the following descriptions about the directions are described according to the directions shown in the drawings, so as to facilitate understanding, and are not limited to the technical solutions. The sample collecting and batching system comprises a first conveying belt device 1, a second conveying belt device 2 and a sample preparing and conveying belt device 3 which are longitudinally arranged in parallel, wherein the front ends of the first conveying belt device 1, the second conveying belt device 2 and the sample preparing and conveying belt device 3 are provided with a front end traversing device 6 which is transversely arranged, and the rear ends of the first conveying belt device 1, the second conveying belt device 2 and the sample preparing and conveying belt device 3 are provided with a rear end traversing device 5 and a sample delivering traversing device 7 which are transversely and parallelly arranged; at least one transverse end part of the sample feeding and traversing device 7 is provided with a set of robot sample preparation system 8;

The front end traversing device 6 is used for forward transmitting a plurality of sample barrels transmitted from the outside to the first conveyor belt device 1 and the second conveyor belt device 2 for temporary storage, the rear end traversing device 5 is provided with a code reading component used for reading the sample barrel information forward transmitted by the first conveyor belt device 1, so as to reversely transmit the sample barrels in the same batch to the sample preparation conveyor belt device 3 for concentrated batch collection after traversing, or reversely transmit the sample barrels not in the batch to the second conveyor belt device 2 after traversing, and then forward transmit the sample barrels to the first conveyor belt device 1 again after traversing by the front end traversing device 6 to form cyclic transmission; the sample preparation conveying belt device 3 is used for carrying out automatic sample preparation operation of a robot by the sample preparation system 8 of the robot, wherein the sample preparation conveying belt device is used for positively conveying the same batch of sample barrels subjected to batch collection to the sample delivery traversing device 7 one by one through the rear end traversing device 5 and then traversing the sample delivery traversing device 7 to the end part. The first conveyor belt device 1, the second conveyor belt device 2 and the sample preparation conveyor belt device 3 are all provided with frame fixing components for forming stable installation, and the frame fixing components comprise a bearing frame, frame supporting legs, installation fixing pieces and the like.

The specific implementation principle is as follows:

before sample preparation, under the control of a central control system, an external transmission mechanism (an intelligent transfer trolley 9 described below) transmits a plurality of sample barrels filled with samples to the first and second conveyor belt devices 1 and 2 in a forward direction through a front end transverse moving device 6 (the forward direction is the arrow A direction shown in the figure), so that the first and second conveyor belt devices 1 and 2 bear a plurality of sample barrels in different batches. The specific bearing number can be matched according to the lengths of the first conveyor belt device 1 and the second conveyor belt device 2, and the longer the length is, the more sample barrels can be borne.

Under the control scheduling of the central control system, the first conveying belt device 1 continues to convey forward, so that the first sample barrel on the first conveying belt device 1 is conveyed to the rear-end transverse moving device 5, and then a code reading component on the rear-end transverse moving device 5 reads information of the sample barrel (a two-dimensional code or a chip can be arranged on the sample barrel, which is the prior art, and the two-dimensional code and the chip record information of samples in the sample barrel, so that the code reading component can judge whether the sample barrel is a first sample barrel needing to be prepared according to the information). If the sample barrel is just the first sample barrel of the batch to be prepared, the rear end traversing device 5 drives the sample barrel to transversely transmit (e.g. to the right in the figure) so as to transmit the sample barrel to the tail end of the sample conveyer belt device 3, and then the rear end traversing device 5 and the sample conveyer belt device 3 are reversely transmitted (reverse transmission direction is shown as arrow B in the figure) to reversely transmit the sample barrel to the sample conveyer belt device 3 for centralized batching. And then the rear end traversing device 5 traverses back to the tail end of the first conveying belt device 1, the first conveying belt device 1 continuously transmits the second sample barrel forward to the rear end traversing device 5 for reading codes, if the sample barrel is still the batch of sample barrels, the second sample barrel is continuously transmitted to the sample conveying belt device 3 for centralized batch collection as described above until all sample barrels of the batch are transmitted to the sample conveying belt device 3 for centralized batch collection.

If the second sample barrel code reading judgment does not belong to the batch, the rear end traversing device 5 transversely transmits the sample barrel to the tail end of the second conveying belt device 2 beside, and then the rear end traversing device 5 and the second conveying belt device 2 reversely transmit the sample barrel to the second conveying belt device 2 at the same time. The last sample bucket located at the second conveyor means 2 (if the full conveyor line of the second conveyor means 2 is already full of sample buckets) is then reversely transferred to the front traversing means 6 due to the reverse transfer of the second conveyor means 2. At this time, the front end traversing device 6 drives the sample barrel to traverse the first conveyor device 1, and the front end traversing device 6 and the first conveyor device 1 are all transported forward, so that the last sample barrel originally located on the second conveyor device 2 is transported to the first conveyor device 1 again. That is, by such special cooperation, the first conveyor belt device 1, the rear end lateral movement device 5, the second conveyor belt device 2 and the front end lateral movement device 6 form a counter-clockwise transmission circulation system, so that sample barrels of non-current sample preparation batches can be circularly transmitted for circular scanning operation, and all sample barrels of the first batch can be finally transmitted to the sample preparation conveyor belt device 3 for centralized batch collection. And all sample barrels are circularly transmitted, so that the sample collection and batch collection operation is completed, the occupied area of a circulation system is small, the circulation is fast, and the efficiency is high.

After all sample barrels of the first batch are transmitted to the sample preparation conveyor belt device 3 for centralized batch collection, the rear end traversing device 5 traverses to the tail end of the sample preparation conveyor belt device 3, and then the sample preparation conveyor belt device 3, the rear end traversing device 5 and the sample delivery traversing device 7 all forward transmit, so that the first sample barrels of the batch are transmitted to the sample delivery traversing device 7. Then the sample barrel is driven to transversely move to the robot sample preparation system 8 at the end part by the sample feeding transverse moving device 7, so that the robot sample preparation system 8 obtains the sample barrel and performs material pouring. According to the principle, all sample barrels of the first batch are transmitted to the robot sample preparation system 8 for pouring, and then the robot automatic sample preparation operation of the batch is carried out. And then carrying out sample collection and preparation operation of all the sample barrels of the second batch according to the logic until all the sample barrels are subjected to sample preparation operation.

In this embodiment, the two lateral ends of the sample-feeding and traversing device 7 are provided with a set of robotic sample-making system 8, so that two sets of sample-making operations can be performed simultaneously by using the sample-feeding and traversing device 7, and the working efficiency is higher.

The transverse transmission track means is shown as C and the longitudinal movement platform means is shown as D.

The specific implementation principle is as follows:

For example, under the control and dispatch of the central control system, the longitudinal moving platform device of the rear end traversing device 5 moves transversely along the transverse transmission track device arranged transversely, so that the longitudinal moving platform device moves to the rear ends of the first transmission belt device 1 and the second transmission belt device 2, then the first transmission belt device 1 is transmitted forward, so that the first sample barrel on the first transmission belt device 1 is transmitted to the longitudinal moving platform device, and then the read code component on the rear end traversing device 5 reads the sample barrel information. If the sample barrel is just the first sample barrel of the batch to be prepared, the longitudinal moving platform device moves transversely along the transverse conveying track device which is transversely arranged again, so that the longitudinal moving platform device drives the sample barrel to transversely convey (such as conveying towards the right in the figure), the sample barrel is conveyed to the tail end of the sample preparation conveying belt device 3, then the longitudinal moving platform device (namely a roller conveyor) and the sample preparation conveying belt device 3 are reversely conveyed (reverse conveying direction is shown as arrow B in the figure), and the sample barrel is reversely conveyed to the sample preparation conveying belt device 3 for centralized batch collection.

Then the longitudinal moving platform device of the rear end traversing device 5 traverses and returns to the tail end of the first conveying belt device 1 along the transverse conveying track device which is transversely arranged, and the first conveying belt device 1 continuously transmits the second sample barrel to the longitudinal moving platform device in the forward direction for code reading. If the second sample barrel code reading judgment does not belong to the batch, the whole longitudinal moving platform device is kept motionless, the sample barrel which is originally positioned on the left side of the longitudinal moving platform device is directly hooked on the right side of the longitudinal moving platform device by a barrel hooking mechanism, and then the longitudinal moving platform device (namely a roller conveyor) and the second conveyor belt device 2 are reversely conveyed (the reverse conveying direction is shown as an arrow B direction in the figure), and the sample barrel is reversely conveyed to the second conveyor belt device 2. Through setting up hook bucket mechanism, this makes vertical moving platform device can wholly keep motionless, and the receipts of next sample bucket and the code reading operation that can be quick are high in degree of automation, easily control, work efficiency is high.
