Description

Technical Field

[0001] This utility model relates to the field of ore conveying technology, specifically a dust removal device for ore conveyor belts. Background Technology

[0002] Ore conveyor belts are widely used in mines or coal mines and other environments. They are conveyor belts used to transport ore, usually made of rubber and fabric composites. They are mainly used in belt conveyors to transport ore from one place to another through a continuous conveyor belt, achieving efficient and continuous material transportation.

[0003] Various ores are transported using conveyor belts during production. As the ore is transported from one conveyor belt to another, the drop height creates positive pressure at the drop point, generating significant dust. Direct release of this dust into the air severely pollutes the mining area and surrounding environment. Therefore, a dust removal device is needed above the overlap point of the upper and lower conveyor belts to treat the dust. Most existing dust removal devices simply install a dust cover at the overlap point with a dust suction device inside. However, this type of device is simple in structure and has poor dust removal efficiency, resulting in a large amount of dust escaping and impacting the mining environment. Therefore, to address these issues, we propose a dust removal device for ore conveyor belts. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for ore conveyor belts, in order to solve the problem that most existing dust removal devices install a dust cover at the overlapping point and then install a dust suction device inside for dust removal. However, such dust removal devices have a simple structure and poor dust removal effect, resulting in a lot of dust being emitted, which affects the mining area environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dust removal device for an ore conveyor belt includes an upper conveyor belt, a lower conveyor belt, and a dust cover. The lower conveyor belt is located on the lower right side of the upper conveyor belt, and the dust cover is located on the outer side of the upper right side of the upper conveyor belt. A water tank is installed on the upper left side of the dust cover, and a water inlet pipe is installed on the upper end of the water tank. A connecting pipe is fixedly connected to the lower end of the water tank, and a nozzle is fixedly connected to the lower end of the connecting pipe. A pressure valve is provided at the front end of the nozzle. A dust collection device is installed on the upper right side of the dust cover, and a dust collection port is fixedly connected to the lower end of the dust collection device. A connecting plate is provided on the inner right side of the dust cover, and a screw is fixedly connected to the upper end of the connecting plate. An internal threaded cap is detachably threaded to the outer side of the upper part of the screw, and a handle is fixedly connected to the upper end of the internal threaded cap. A flexible baffle is installed on the lower end of the connecting plate, and a counterweight is installed on the lower end of the flexible baffle. Dense fine brushes are fixedly connected to both ends of the flexible baffle.

[0007] Preferably, the left side of the lower conveyor belt is located inside the dust cover, the dust cover is hollow, and the water tank is located on the left side of the dust collection device.

[0008] Preferably, the connecting pipe passes through the inner side of the upper end of the dust cover, the upper end of the nozzle is fixedly connected to the inner wall of the upper end of the dust cover, and the water inlet pipe, water tank, connecting pipe and nozzle are interconnected.

[0009] Preferably, the nozzle is located on the upper right side of the upper conveyor belt, the dust suction port is located on the upper left side of the lower conveyor belt, and the dust suction port is located on the left side of the connecting plate.

[0010] Preferably, the upper end of the screw passes through the inner side of the upper end of the dust cover, and there are three screws, three internal thread caps, and three handles. The lower end face of the internal thread cap is in contact with the upper end face of the dust cover, and there are several flexible baffles and counterweights that are evenly arranged.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by setting up a water tank, water inlet pipe, connecting pipe, nozzle, pressure valve, flexible baffles, counterweight, and dense fine brush, during the process of transporting ore from the upper conveyor belt to the lower conveyor belt, the water source in the water tank first flows into the connecting pipe, and then the pressure valve is activated, and water mist is sprayed out from the nozzle. This causes some of the dust on the surface of the ore to adhere to the surface of the ore due to the water mist, effectively reducing the amount of dust generated when the ore is transported to the lower conveyor belt. Then, the dust collection equipment is activated, and the dust collection equipment absorbs and removes the small amount of dust through the suction port. At the same time, multiple flexible baffles, counterweights, and dense fine brushes work together to block the right outlet of the dust cover, thereby effectively reducing the amount of dust escaping. This device can reduce the dust generated by the drop in elevation when the ore is transported from the upper conveyor belt to the lower conveyor belt, and at the same time, it blocks the dust inside the dust cover, reducing the amount of dust escaping from the right outlet of the dust cover, making the dust collection equipment more effective and effectively reducing the impact of dust on the mining area environment.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A dust removal device for an ore conveyor belt includes an upper conveyor belt 1, a lower conveyor belt 2, and a dust cover 3. The lower conveyor belt 2 is located on the lower right side of the upper conveyor belt 1, and the dust cover 3 is located on the upper right outer side of the upper conveyor belt 1. A water tank 4 is installed on the upper left side of the dust cover 3, and a water inlet pipe 5 is installed on the upper end of the water tank 4. A connecting pipe 6 is fixedly connected to the lower end of the water tank 4, and a nozzle 7 is fixedly connected to the lower end of the connecting pipe 6. A pressure valve 8 is provided at the front end of the nozzle 7. A dust suction device is installed on the upper right side of the dust cover 3. The device 9 has a suction port 10 fixedly connected to its lower end. The dust cover 3 has a connecting plate 11 on the right side inside. The connecting plate 11 has a screw 12 fixedly connected to its upper end. The screw 12 has an internal thread cap 13 detachably threadedly connected to its upper outer side. The internal thread cap 13 has a handle 14 fixedly connected to its upper end. The connecting plate 11 has a flexible baffle 15 installed at its lower end. The flexible baffle 15 has a counterweight 16 installed at its lower end. The flexible baffle 15 has dense fine brushes 17 fixedly connected to both its front and rear ends.

[0021] The lower conveyor belt 2 is located on the left side inside the dust cover 3. The dust cover 3 is hollow inside. The water tank 4 is located on the left side of the dust collection device 9. The connecting pipe 6 passes through the inner side of the upper end of the dust cover 3. The upper end of the nozzle 7 is fixedly connected to the inner wall of the upper end of the dust cover 3. The water inlet pipe 5, water tank 4, connecting pipe 6 and nozzle 7 are interconnected. The nozzle 7 is located on the upper right side above the upper conveyor belt 1. The dust collection port 10 is located on the upper left side above the lower conveyor belt 2. The dust collection port 10 is located on the left side of the connecting plate 11. The upper end of the screw 12 passes through the inner side of the upper end of the dust cover 3. There are three screws 12, three internal thread caps 13 and three handles 14. The lower end face of the internal thread cap 13 is attached to the upper end face of the dust cover 3. The flexible baffle 15 is also present. The upper conveyor belt 1 has several counterweights 16, which are evenly distributed. A lower conveyor belt 2 is located on the lower right side of the upper conveyor belt 1. A dust cover 3 is located on the outer right side of the upper conveyor belt 1. A water tank 4 is installed on the upper left side of the dust cover 3. This facilitates the installation of the water tank 4, inlet pipe 5, connecting pipe 6, nozzles 7, pressure valve 8, flexible baffles 15, counterweights 16, and dense fine brushes 17. During the transport of ore from the upper conveyor belt 1 to the lower conveyor belt 2, the water in the water tank 4 first flows into the connecting pipe 6, then the pressure valve 8 is activated, and water mist is sprayed from the nozzles 7. This causes some dust on the ore surface to adhere to the ore surface due to the water mist, effectively reducing the amount of dust transported to the lower conveyor belt. Conveyor belt 2 generates a significant amount of dust. The dust collection device 9 is then activated, using suction ports 10 to remove a small amount of dust. Simultaneously, multiple flexible baffles 15, counterweights 16, and dense fine brushes 17 work together to block the right-side outlet of the dust cover 3, effectively reducing dust escape. This device reduces dust generated by the drop in elevation during ore transport from the upper conveyor belt 1 to the lower conveyor belt 2. It also blocks dust within the dust cover 3, reducing dust escape from the right-side outlet, resulting in better dust removal by the dust collection device 9 and effectively reducing the impact of dust on the mining environment. A water inlet pipe 5 is installed at the top of the water tank 4. A connecting pipe 6 is fixedly connected to the lower end of the water tank 4. A nozzle 7 is fixedly connected to the lower end of the connecting pipe 6. A pressure valve 8 is provided at the front end of the nozzle 7. A vacuum cleaner 9 is installed on the upper right side of the dust cover 3. A vacuum port 10 is fixedly connected to the lower end of the vacuum cleaner 9. A connecting plate 11 is provided on the inner right side of the dust cover 3. A screw 12 is fixedly connected to the upper end of the connecting plate 11. An internal thread cap 13 is detachably threaded on the outer side of the upper part of the screw 12. A handle 14 is fixedly connected to the upper end of the internal thread cap 13. A flexible baffle 15 is installed at the lower end of the connecting plate 11. A counterweight 16 is installed at the lower end of the flexible baffle 15. Dense fine brushes 17 are fixedly connected to both the front and rear ends of the flexible baffle 15.

[0022] Workflow: When in use, the device is powered by an external power source. Water flows into the water tank 4 through the water inlet pipe 5. During the transport of ore from the upper conveyor belt 1 to the lower conveyor belt 2, the ore first enters from the left side of the dust cover 3. At this time, the water in the water tank 4 flows into the connecting pipe 6. Then, the external controller activates the pressure valve 8, causing water mist to spray out from the nozzle 7. This causes some dust on the surface of the ore to adhere to the surface due to the water mist, effectively reducing the amount of dust generated during the ore transport from the upper conveyor belt 1 to the lower conveyor belt 2 due to the drop. Then, the dust collection equipment 9 is activated. The dust collection equipment 9 absorbs and removes a small amount of dust through the suction port 10. Simultaneously, multiple flexible baffles 15, counterweights 16, and dense fine brushes 17 work together to block the right outlet of the dust cover 3, effectively reducing dust escaping from the right outlet of the dust cover 3, increasing the dust absorption capacity of the dust collection equipment 9, and effectively reducing dust accumulation. To mitigate the impact of dust on the mining environment, the counterweight 16 ensures that the flexible baffle 15 always hangs downwards, reducing the likelihood of it lifting off. The dense fine brush 17 reduces the gap between two adjacent flexible baffles 15, thus improving the baffle's barrier effect and reducing dust escape. As the lower conveyor belt 2 transports ore outwards, the ore pushes up the lower side of the flexible baffle 15 and moves out of the dust cover 3. This pushing up also causes wear on the lower left side of the flexible baffle 15. When the flexible baffle 15 is damaged, turn the handle 14 outwards. The handle 14 drives the internal thread cap 13 outwards, causing it to disengage from the screw 12 and be removed. Then, pull the connecting plate 11 downwards, causing it to move the screw 12 downwards, allowing the screw 12 to leave the inside of the dust cover 3. This allows the flexible baffle 15 to be removed and replaced entirely. This replacement operation is simple and does not affect subsequent use.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
