Description

A dual-shaft high-efficiency unloading device for kneading materials

Technical Field

The utility model relates to the technical field of unloading devices, in particular to a double-shaft high-efficiency unloading device for kneading materials.

Background Art

In the production process of shaped coal, qualified raw coal is generally purchased from the coal preparation plant. After the raw coal is crushed, screened and measured in turn, it is mixed and kneaded with asphalt, tar, additives, etc., and then heated and kept warm. After heating and keeping warm, it is molded to obtain semi-finished shaped coal. The semi-finished shaped coal enters the carbonization furnace for carbonization, and finally the finished shaped coal is obtained after quenching. Among them, a kneading pot is needed for stirring and kneading. The kneading pot is a special equipment for stirring and mixing raw materials such as raw coal, tar, asphalt, additives, etc. The gear box is driven by a motor to drive the stirring device to rotate at high speed to achieve uniform mixing and distribution of various raw materials.

After the kneading pot completes the mixing and mixing of various raw materials, the kneading material needs to be discharged. At present, the structure adopted by the kneading pot unloading plant is to turn the pot body or set the discharge port at the bottom. When unloading, the pot body is rotated to a certain angle to tilt toward the discharge port by the transmission mechanism, and the stirring blade is rotated at the same time to discharge the kneading material. This unloading method often has the following problems: First, the unloading is carried out by the gravity of the kneading material itself. Due to the high viscosity of the kneading material, the entire unloading process takes a long time, and the unloading efficiency is not high. At the same time, the unloading amount is sometimes large and sometimes small, and there is also the problem of uneven unloading; second, there is the problem of unclean unloading, and there will always be a small part of the material left. This part of the material is mixed into the next pot for stirring, which not only wastes energy, but also affects production capacity. At the same time, due to the heavy weight of the kneading pot itself, it also has certain safety hazards when it is tilted. Therefore, it is objectively necessary to develop a dual-axis high-efficiency unloading device for kneading materials with fast unloading speed, uniform and thorough unloading, and safe and reliable unloading.

The faster the rotation speed of the rotating shaft, the greater the centrifugal force generated, and the faster the kneaded materials can be thrown out. It can be seen that when unloading, the present invention relies on both the gravity of the kneaded materials themselves and the centrifugal force generated when the rotating shaft rotates. The combination of the two can effectively overcome the viscosity of the kneaded materials, shorten the unloading time, and improve the unloading efficiency. At the same time, the unloading process is to sequentially discharge the materials in each storage space.

DETAILED DESCRIPTION

The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the present invention belong to the protection scope of the present invention.

As shown in Figures 1 and 2, the utility model includes a shell 1 with an open upper end and a discharge port 2 arranged in the middle position of the bottom of the shell 1. Two discharge mechanisms are symmetrically arranged in the shell 1, and each discharge mechanism includes a rotating shaft 3 and a discharge plate 4 uniformly distributed on the rotating shaft. The two ends of the rotating shaft 3 are respectively connected to the two side walls of the shell 1 for sealing rotation. One end of the rotating shaft 3 is connected to a driving mechanism for driving the rotating shaft 3 to rotate. The driving mechanism is a prior art, which can drive the rotating shaft 3 to rotate at a uniform speed and the speed is adjustable. The uniform rotation of the rotating shaft 3 realizes uniform unloading, and the adjustable speed of the rotating shaft 3 realizes the adjustment of the unloading speed. The distance between the two rotating shafts 3 in the two unloading mechanisms is twice the width of the discharge plate 4. The cross-sectional shapes of the two sides of the bottom of the shell 1 are arc-shaped, and the outer side surfaces of the discharge plates 4 of the two unloading mechanisms are respectively consistent with the inner walls of the two arcs.

The utility model is installed at the bottom of a kneading pot and is used for discharging kneaded materials. When the materials are stirred, one of the two discharging plates 4 of the two discharging mechanisms is in a horizontal state. At this time, the ends of the two discharging plates 4 of the two discharging mechanisms are in contact with each other. At the same time, the outer side surface of one of the discharging plates 4 is in contact with the arc-shaped portion of the bottom of the shell body 1, so that a seal is formed to prevent the kneaded materials that have not been stirred from flowing out of the discharging port 2. When the materials are stirred and need to be discharged, the two rotating shafts 3 are driven to rotate synchronously by the driving mechanism, so that the two rotating shafts 3 have the same rotation speed and opposite rotation direction, and gradually drive the kneaded materials to move downward, and finally the kneaded materials are discharged from the discharging port 2. In the present invention, a storage space 16 is formed between every two adjacent discharge plates 4, and the kneaded materials will first fill up these storage spaces 16. During the unloading process of the kneaded materials, the rotating shaft 3 drives the discharge plate 4 to rotate, thereby driving the kneaded materials in each storage space 16 to rotate. When the storage space 16 opens downward, the unloading begins. On the one hand, the kneaded materials leave the storage space 16 under the action of their own gravity, and on the other hand, the centrifugal force generated by the rotation will throw the kneaded materials in the storage space 16 out. The faster the rotation speed of the rotating shaft 3, the greater the centrifugal force generated, and the faster the kneaded materials can be thrown out. It can be seen that when unloading, the present invention relies on both the gravity of the kneaded materials themselves and the centrifugal force generated when the rotating shaft 3 rotates. The combination of the two can effectively overcome the viscosity of the kneaded materials, shorten the unloading time, and improve the unloading efficiency. At the same time, the unloading process is to sequentially discharge each storage space 16. The kneaded materials in the space 16 are unloaded, that is, the kneaded materials in the previous storage space 16 are unloaded first, and then the kneaded materials in the adjacent rear storage space 16 are unloaded. It is only necessary to ensure that the rotating shaft 3 rotates at a uniform speed to ensure the uniformity of the unloading of the kneaded materials. Secondly, the utility model is arranged at the bottom of the kneading pot, and the kneaded materials will all fall into the interior of the utility model. Under the combined action of its own gravity and centrifugal force, the kneaded materials can be discharged from the discharge port 2 more cleanly and thoroughly without omission, which solves the existing problem of unclean unloading, prevents these kneaded materials from mixing into the next pot, avoids wasting energy and affecting production capacity. At the same time, the discharge port 2 of the utility model is located at the bottom of the shell 1, and the kneaded materials can be discharged cleanly without tilting the kneading pot during unloading, and the safety hazards caused by the tilting of the kneading pot are eliminated, making the unloading of the kneaded materials safer and more reliable.

The driving mechanism includes a motor 5, a driving gear 6 and a driven gear 7. The motor 5 and the driving gear 6 are mounted on one of the rotating shafts 3. The driven gear 7 meshes with the driving gear 6 and is mounted on the other rotating shaft 3. During operation, the motor 5 drives the rotating shaft 3 connected thereto to rotate, the rotating shaft 3 drives the driving gear 6 to rotate, the driving gear 6 drives the driven gear 7 to rotate, and the driven gear 7 drives the rotating shaft 3 connected thereto to rotate, thereby achieving a synchronous rotation state in which the two rotating shafts 3 rotate at the same speed and in opposite directions, thereby meeting the use requirements of the unloading device.

A wear-resistant layer 8 is provided on the inner wall of the arc-shaped part on both sides of the bottom of the shell 1. When the utility model is in operation, the end of the discharge plate 4 contacts the inside of the shell 1 and rubs against the inner wall of the shell 1 during continuous rotation. As time goes by, this friction may cause wear inside the shell 1, thereby accelerating the damage of the shell 1. In order to extend the service life of the shell 1, a wear-resistant layer 8 is provided on its inner wall. This wear-resistant layer 8 can be a coating or a surfacing layer. It is formed after processing and has high wear resistance, thereby extending the service life of the shell 1.

In order to facilitate the installation and disassembly of the utility model, a flange 9 is provided at the upper end of the shell 1. During actual production, other connecting structures may also be selected.

The discharge plate 4 is provided with a spring sheet 10, and the end of the spring sheet 10 is against the inner wall of the arc-shaped portion at the bottom of the housing 1. The discharge plate 4 rotates with the rotating shaft 3, and its end is constantly rubbed against the housing 1 during the rotation process. As the use time increases, the end of the discharge plate 4 is worn out, which may cause leakage of part of the material in the kneading pot. After the spring sheet 10 is provided, the end of the spring sheet 10 can always press the inner wall of the housing 1 under the action of its own elastic force, thereby filling the gap between the discharge plate 4 and the housing 1, preventing leakage of materials, and ensuring the long-term normal operation of the device.

Ring plates 11 are provided at both ends of the rotating shaft 3 near the inner wall of the shell 1, and both ends of the discharge plate 4 are fixed on the two ring plates 11 respectively. During the use of the device, it is found that one end of the discharge plate 4 is fixed on the rotating shaft 3, and the other end is in contact with the inner wall of the shell 1, and is used to scrape off the kneaded material adhering to the inner wall of the shell 1. As the use time increases, the discharge plate 4 may produce certain deformations such as warping and skewing, which affects the normal use of the device. After the ring plates 11 are provided at both ends of the rotating shaft 3 and the two ends of the discharge plate 4 are fixed on the ring plates 11, the rotating shaft 3, the discharge plate 4 and the ring plates 11 are connected to form a whole, which improves the overall stability, and also improves the rigidity and strength of the discharge plate 4, and reduces the possibility of the discharge plate 4 producing deformations such as warping and skewing.

The discharge port 2 is provided with a sealing door 12 which can be opened and closed automatically. The sealing door 12 is a prior art which can be opened and closed automatically and can seal the discharge port 2. When the kneading pot is stirring the materials, the sealing door 12 is closed to prevent the materials in the pot from being discharged from the discharge port 2 in case of an accident, thereby improving the safety of the setting and operation. When the kneading pot completes the stirring of the materials, the sealing door 12 is opened to facilitate the discharge of the mixed materials from the discharge port 2.

The unloading plate 4 includes a fixed part 13, a connecting part 14 and a movable part 15. The fixed part 13 is fixedly connected to the rotating shaft 3. One side of the connecting part 14 is fixedly connected to the fixed part 13, and the other side is processed with a waist-shaped hole. A through hole is processed on the movable part 15, and the waist-shaped hole and the through hole are connected by bolts. When the utility model is in operation, the end of the discharge plate 4 contacts the inner wall of the shell 1 and rubs against the inner wall of the shell 1. As the use time increases, the end of the discharge plate 4 is constantly worn, resulting in a shortened width of the discharge plate 4, so that a gap appears between the end of the discharge plate 4 and the inner wall of the shell 1. Similarly, the distance between the two rotating shafts 3 of the two discharge mechanisms will be greater than the sum of the widths of the two discharge plates 4. Then, when the kneading pot is kneading various materials, material leakage will occur. In order to avoid this problem, the traditional treatment method is to replace the discharge plate 4, which incurs a large maintenance cost and increases the operating cost. In order to reduce the cost, the discharge plate 4 is arranged to be composed of three parts: a fixed part 13, a connecting part 14 and a movable part 15, wherein the movable part 15 is connected to the fixed part 13 through the connecting part 14. When necessary, the bolts between the movable part 15 and the connecting part 14 can be loosened to adjust the position of the movable part 15, thereby adjusting the width of the discharge plate 4 so that it can always be in contact with the inner wall of the shell 1, thereby extending the service life of the discharge plate 4, reducing the maintenance cost of the device, and reducing the operating cost of the entire device.
