Description

Technical Field

[0001] The invention relates to the technical field of dust suppression and reduction, and in particular to a dust suppression and reduction system for a car tipper to unload high-dust materials. Background Art

[0002] In the field of modern industrial production and logistics transportation, car dumpers are widely used as efficient material unloading equipment in ports, mines, thermal power plants and other places to unload various bulk materials such as coal, ore, coke, etc. However, in the process of car dumpers unloading high-dust materials, extremely serious dust pollution problems will be caused.

[0003] In the traditional car dumper operation mode, when a car filled with high-dust materials is turned over, a large amount of materials pour out under the action of gravity, instantly generating strong air flow disturbances. These disturbed airflows carry the fine dust particles in the materials and diffuse them around. Taking the coal car dumper as an example, during the unloading process, the coal particles rub and collide with each other, and the dust concentration generated can be as high as tens of milligrams or even hundreds of milligrams per cubic meter, far exceeding the national workplace air quality standards.

[0004] High dust environment not only poses a huge threat to the health of on-site operators, but long-term inhalation of dust can easily lead to a variety of occupational diseases such as pneumoconiosis and respiratory diseases. At the same time, the diffuse dust will also have a negative impact on the surrounding ecological environment, settling on the surrounding vegetation and soil, affecting vegetation growth and polluting soil quality. In addition, the accumulation of dust in the air also increases the risk of explosion. Once it encounters a fire source, it is very easy to cause a dust explosion accident, which will bring disastrous consequences to the company.

[0005] In order to deal with this serious problem, although there have been some simple dust prevention measures before, such as setting up simple windbreaks around the tipping machine, the windproof and dust suppression effects are very limited and cannot fundamentally curb the generation and spread of dust. Some companies also use water sprinkling to reduce dust, but due to uneven water sprinkling and difficulty in accurately controlling the amount of water, it often leads to excessive moisture content in the material affecting subsequent processing, or new problems such as equipment failure due to icing in winter. Therefore, there is an urgent need to develop an efficient, intelligent and adaptable dust suppression system for tipping machines to unload high-dust materials, so as to achieve effective control of dust, ensure personnel health, environmental safety and the normal production and operation of the enterprise. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems and provide a dust suppression and reduction system for a car tipper to unload high-dust materials.

[0011] Furthermore, a collar is fixedly mounted on the vertical pole, and the collar corresponds to the outer wall of the horizontal tube.

[0012] Furthermore, the bag dust collector box is arranged on the base and between the two horizontal tubes. The bag dust collector box includes an ash hopper and a filter bin. Ash inlet pipes connected to the interior of the ash hopper are fixedly installed on both sides of the ash hopper. The other end of the ash inlet pipe is connected to the interior of the horizontal tube. An air outlet pipe connected to the interior of the filter bin is fixedly installed above the filter bin.

[0013] Furthermore, the blowing pipe passes through the filter bin and extends to the inside of the filter bin. A conical cover is fixedly mounted on the lower end of the blowing branch pipe, and the conical cover is located above the filter element.

[0014] Furthermore, the diameter of the blowing pipe is 3-5 cm, the conical cover is made of polycarbonate material, and the cone angle of the conical cover is 60°-90°.

[0015] Furthermore, the nozzle is designed with a fan-shaped spray port, the spray angle is 120°-150°, and the interval between adjacent nozzles is 20-30 cm.

[0020] In summary, the spray device and the bag dust collection mechanism work together, and the two complement each other to carry out all-round and multi-level dust control from different angles and in different ways. Compared with a single dust reduction or dust collection method, it greatly improves the comprehensive efficiency of the entire dust suppression and dust reduction system, and fundamentally curbs the generation and spread of dust.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] A dust suppression and reduction system for a car tipper unloading high-dust materials according to a preferred embodiment of the present invention will be described in detail below.

[0025] Embodiment 1 like Figure 1 - Figure 7 As shown, a dust suppression and reduction system for a tipping machine 12 to tip high-dust materials includes a base 1, two receiving slots 11 are arranged on the base 1, and the tipping machine 12 is arranged inside the two receiving slots 11. A movable carriage 2 is arranged on the tipping machine 12, and enclosures 13 are fixedly installed on both sides of the base 1 located at the receiving slots 11, and a spray device 3 is arranged on the enclosure 13. A support plate 15 is fixedly installed on one side of the base 1, and a controller 31 is fixedly installed on the support plate 15. A water spray pipe 32 and an air jet pipe 33 are connected to the controller 31, and an air jet branch pipe 331 is connected to the air spray pipe 33. A water spray branch pipe 321 is connected to 32, and the other end of the air jet branch pipe 331 is connected to the inside of the water spray branch pipe 321. A transverse pipe 4 is connected to the water spray branch pipe 321, and a plurality of nozzles 41 are connected to the transverse pipe 4. The base 1 is located between the two accommodating grooves 11 and a bag dust collection mechanism 5 is fixedly installed thereon. The dust collection mechanism includes an enlarged suction port 51 and a bag dust collection box 52. A plurality of filter elements 53 are arranged inside the bag dust collection box 52. A blowing pipe 54 is arranged on the bag vacuum cleaner, and a plurality of blowing branch pipes 541 are fixedly installed below the blowing pipe 54. The blowing branch pipes 541 are located above the filter elements 53.

[0026] Furthermore, the nozzle 41 is designed with a fan-shaped spray port, the spray angle is 120°-150°, and the interval between adjacent nozzles 41 is 20-30 cm.

[0027] During operation, when the material unloading operation starts, the enclosures 13 located on both sides of the receiving tank 11 of the base 1 play a role in initially blocking the spread of dust and reducing the range of dust dissipation to the surrounding environment. The spray device 3 installed on the enclosure 13 is an important part of dust control. The operation of the spray device 3 is precisely controlled by the controller 31 installed on the support plate 15 on one side of the base 1. The controller 31 is connected to the water spray pipe 32 and the jet pipe 33. The jet pipe 33 transports the gas to the part connected to the water spray branch pipe 321 through the jet branch pipe 331 connected thereto. When spray dust reduction is required, water flows from the water spray pipe 32 through the water spray branch pipe 321 to the transverse pipe 4, and at the same time, the gas enters the water spray branch pipe 321 from the jet pipe 33 through the jet branch pipe 331. The two are mixed in the water spray branch pipe 321. This soda-water mixing method makes the water mist sprayed from the multiple nozzles 41 connected to the transverse pipe 4 more fine and uniform, which can more effectively capture the dust particles suspended in the air and greatly improve the dust reduction effect.

[0028] At the same time, the bag dust collection mechanism 5 fixedly installed between the two receiving grooves 11 of the base 1 operates synchronously. The enlarged suction port 51 of the bag dust collection mechanism 5 covers the dust source area as much as possible, and uses suction to suck a large amount of dust-containing air into the bag dust collection box 52. The multiple filter elements 53 arranged inside the bag dust collection box 52 filter the inhaled dust-containing air, and the dust is blocked and intercepted by the filter element 53, and the purified air can be discharged. In order to ensure the continuous and efficient filtering performance of the filter element 53, the spray pipe 54 arranged on the bag dust collector and the multiple spray branches 541 fixedly installed below it play a key role. At a certain time interval or according to the dust adsorption situation, the spray pipe 54 delivers high-pressure gas to the spray branch 541, and the spray branch 541 is aimed at the top of the filter element 53 to spray, shake off the dust attached to the surface of the filter element 53, so that the filter element 53 can be regenerated, ensuring that the bag dust collection mechanism 5 always maintains a good dust collection effect. During the entire high-dust material unloading process, the spray device 3 and the bag dust collection mechanism 5 work together to suppress and reduce the generated dust in an all-round and multi-level manner, effectively ensuring the air quality of the work site and the surrounding environment and meeting environmental protection requirements.

[0032] Furthermore, a collar 61 is fixedly mounted on the vertical pole 6 , and the collar 61 corresponds to the outer wall of the horizontal tube 7 .

[0033] Embodiment 5 like Figure 5 - Figure 7 As shown, the bag dust box 52 is arranged on the base 1 between the two horizontal pipes 7. The bag dust box 52 includes an ash hopper 56 and a filter bin 57. Ash inlet pipes 58 connected to the interior of the ash hopper 56 are fixedly installed on both sides of the ash hopper 56. The other end of the ash inlet pipe 58 is connected to the interior of the horizontal pipe 7. An air outlet pipe 59 connected to the interior of the filter bin 57 is fixedly installed above the filter bin 57.

[0034] Furthermore, the bottom of the ash hopper 56 is a conical structure with a cone angle of 45°-60°, and the cone surface of the ash hopper 56 is coated with a Teflon coating with a thickness of 0.1-0.3 mm.

[0035] Furthermore, the blowing pipe 54 passes through the filter bin 57 and extends to the inside of the filter bin 57 . A conical cover 542 is fixedly mounted on the lower end of the blowing branch pipe 541 , and the conical cover 542 is located above the filter element 53 .

[0036] Furthermore, the diameter of the blowing pipe 54 is 3-5 cm, the conical cover 542 is made of polycarbonate, and the cone angle of the conical cover 542 is 60°-90°.
