Dust device is prevented to conveyer belt

Technical Field

The invention belongs to the field of conveyor belts, and particularly relates to a dust-proof device for a conveyor belt.

Background

In the combined transportation of shipping and railway transportation, the change of bulk cargoes into a container is a common transportation mode and is also commonly called as a bulk change set.

The bulk coke, coal, ore and other bulk goods are loaded into the container by the bulk truck, so that the pollution emission is reduced, and the environmental cost generated by transportation can be effectively reduced.

In the current practical workflow of bulk handling, the goods are generally transported by a conveyor belt, and finally the bulk is loaded into a container by a hopper. And in the process of dumping bulk cargos to the conveyor belt, a large amount of smoke dust can be generated by the bulk cargos, and certain dust can be generated when the bulk cargos are transported on the conveyor belt, so that the bulk cargos have a great influence on the health of workers on the scene, and the environment around the collection place is polluted, so that the cost of environmental treatment is increased.

In the prior art, a dust-proof device of a conveyor belt is additionally arranged, a baffle is covered on the whole conveyor belt in a simple manner, or dust-proof equipment is built at a single blanking opening, for example, a Chinese patent with the application number of 2011101341461 introduces a dust cover with a double-layer structure, dust is collected by combining an air guiding pipe through the double-layer structure, the dust cover is laid right above the conveyor belt, the dust cover is fully-covered dust cover, a channel is reserved for a blanking pipeline, and the dust cover is only suitable for being applied to the middle part of the work of the conveyor belt and cannot take the blanking position and the discharging position into consideration.

Further usage scenario is the introduction of the wharf bulk change set, a plurality of hoppers for charging are usually corresponding to the lower part of the conveyor belt, the conveyor belt is usually required to move in order to adapt to the hoppers at all positions, so that the position of the conveyor belt for discharging can be changed along with the movement of the conveyor belt, and if a fully-covered dustproof structure is adopted, the requirement of actual charging cannot be met.

Therefore, a new design is needed that can effectively reduce smoke dust generation in the process of discharging and transporting bulk cargo, and is suitable for normally discharging the discharging pipeline at each position.

Detailed Description

The invention is further described below in connection with specific embodiments.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.

In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.

Example 1

As shown in fig. 1 and 2, the main structure of the present invention is a fixing frame 5 disposed above a conveyor belt 1.

The length of the fixing frame 5 is the same as the total length of the conveyor belt 1, the whole conveyor belt 1 can be completely covered, two lower baffles 2 are arranged below the fixing frame 5, and the direction of the lower baffles 2 is the same as the conveying direction of the conveyor belt 1. The lower baffles 2 on the left and right sides completely shield the left and right sides of the conveyor belt 1, and the lower baffles 2 are only slightly contacted with the belt of the conveyor belt 2, so that the normal operation of the conveyor belt 1 is not affected.

The inner side above the fixed frame 5 is provided with a dustproof curtain 3, the dustproof curtain 3 is provided with a left dustproof curtain and a right dustproof curtain, one side, which is connected with the inner side wall of the fixed frame 5, of the two dustproof curtains 3 is a fixed side, and the other side, which corresponds to the fixed side, is a movable side which can freely move. The width of the cross section of the dustproof curtain 3 is larger than half of the width of the cross section of the fixing frame 5, so that when the two dustproof curtains 3 are in a closed state, the movable edges of the dustproof curtains 3 are mutually overlapped to form a structure with a herringbone cross section, as shown in figure 1. The movable edge of the dustproof curtain 3 is also embedded with a magnetic stripe, which is mainly used for improving the tightness between the two dustproof curtains 3 and can better block the flying dust excited by the running bulk cargo on the conveyor belt 1.

The movable edges of the dustproof curtains 3 are provided with a pull rope 4 at a certain distance, the other one of the pull ropes 4 is connected with a fixing frame 5, and the two dustproof curtains 3 are pulled away from the middle to enter a mouth of a discharging pipeline by simultaneously tensioning the pull ropes 4 to two sides. After the blanking pipeline enters, the pull rope 4 is loosened, and under the influence of gravity and the magnetic strips of the movable edges of the dustproof curtains 3, the two dustproof curtains 4 can be folded and attached around the outer side of the blanking pipeline, so that scattering of flying dust is further reduced.

The choice of the material of the dust-proof curtain 3 is not particularly limited, and any material which satisfies moderate hardness, can deform to a certain extent and is wear-resistant can be used as the dust-proof curtain 3, and the curtain which is made of wear-resistant rubber materials in the embodiment can be well adapted to the requirements of the dust-proof curtain 3, and has lower cost.

In this embodiment, the pull ropes 4 are manually pulled, each pull rope 4 is correspondingly provided with a group of pulleys on the side wall of the fixing frame 5, and the outer side wall of the fixing frame 5 is provided with a hand lever 6 for pulling the pull ropes 4.

When in actual use, an operator determines the specific position of the blanking pipeline, tightens the pull rope 4 at the corresponding position through the hand-operated rod 6, and opens the dustproof curtain 3 at the preset position of the blanking pipeline to form an opening for the blanking pipeline to pass through. And then the pull rope 4 is loosened, and the dustproof curtain 3 is folded under the influence of gravity and the magnetic stripe and is tightly adhered around the outer side wall of the blanking pipeline. At this time, the blanking pipeline performs blanking, bulk cargos directly go down on the conveyor belt 1, and the lower baffle plates 2 on the left side and the right side of the conveyor belt 1 and the dust-proof curtain 3 above can completely limit dust generated during blanking inside and cannot be dissipated to the outside field.

Example 2

The structure of this embodiment is exactly the same as that of embodiment 1, except that no hand rocker 6 is provided on the outside of the fixing frame 5, and tightening and loosening of the pull rope 4 are controlled by a motor 7, as shown in fig. 3.

The manual control dustproof curtain 3 is opened and closed and is converted into the electric control dustproof curtain 3 to be opened and closed, and the manual control dustproof curtain is mainly used for being applicable to the environment where the conveyor belt 1 is located and is dangerous and easy to cause accidents. For example, in the place where harbour is changed, the height of the conveyor belt 1 is generally high, and manual control is dangerous.

Compared with the scheme of a totally-enclosed conveyor belt and a fixed-point blanking opening in the prior art, the scheme of the invention is more flexible in working, any position of the whole conveyor belt can be used as a fixed position of a blanking pipeline, and blanking can be simultaneously carried out no matter how many blanking pipelines are, for example, a plurality of bins can be used for blanking simultaneously in actual transportation, if a traditional structure is adopted, the blanking pipeline for blanking needs to be replaced to enter the fixed blanking pipeline position after the blanking of a single bin is completed, the scheme can be optionally placed, and the blanking of the next bin can be directly carried out after the blanking of the former bin is completed. For example, the conveyor belt 1 is a movable conveyor belt, and the discharging position of the last section of the conveyor belt and the position of the discharging pipeline are adjusted by moving the conveyor belt 1.

The main functions of the invention are to reduce dust generated when bulk cargoes are discharged onto the conveyor belt 1 and the conveyor belt 1 carries out bulk cargo transportation, and compared with various fully-sealed conveyor belt designs in the prior art, the invention has the advantages of more flexible use and more adaptive scenes, and the dustproof curtain 3 at the whole top can be opened, thereby being more convenient for overhauling when the conveyor belt fails and better ensuring the safety of overhaulers.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
