Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, specifically to a dust removal device for preventing dust explosions. Background Technology

[0002] When electrical equipment is in operation, if the content of combustible dust in the gas is high, the sparks generated by the electrical equipment during use may ignite the combustible dust in the gas, thereby damaging the equipment. Therefore, dust removal equipment should be used to reduce the content of combustible dust in the gas.

[0003] Existing dust control devices typically use fans to draw dust into the system, which then filters and collects the combustible dust through internal filter bags or similar devices. This method can reduce the amount of combustible dust in the air. However, over time, more and more combustible dust accumulates on the filter bags, causing blockage of the filter mesh and gradually reducing the amount of gas passing through the filter bags. This results in ventilation obstruction, reduced dust collection capacity, and the need for frequent disassembly and cleaning, causing inconvenience to production and high operating and management costs.

[0004] In summary, existing dust treatment devices suffer from the problem of filter screen clogging, which gradually reduces the amount of gas passing through the filter bag, requiring frequent disassembly and cleaning. Utility Model Content

Therefore, this invention provides a dust removal device to prevent dust explosions.

[0006] The technical solution of this utility model is: a dust removal device for preventing dust explosion, comprising: an explosion-proof cylinder and an air supply mechanism, wherein the explosion-proof cylinder has a dust removal chamber that extends through both sides, one side of the dust removal chamber is an air inlet and the other side of the dust removal chamber is an air outlet, and the air supply mechanism is used to allow gas to enter from the air inlet and be discharged from the air outlet.

[0007] A dust removal assembly and a first filter screen are provided between the top and bottom walls of the dust removal chamber. The dust removal assembly is located on the side closer to the air inlet, and the first filter screen is located on the side farther away from the air inlet.

[0008] The dust removal assembly includes a water outlet seat, a wet curtain, and a water collection seat connected in sequence. The water collection seat is connected to the water storage tank at the bottom of the explosion-proof cylinder through a first drain pipe.

[0009] Furthermore, it also includes: a delivery pump, the inlet of which is connected to the water storage tank, the outlet of which is connected to the outlet seat through a second drain pipe, and a second filter screen is provided inside the water storage tank.

[0010] Furthermore, the air supply mechanism includes a first fan and a second fan installed in the dust removal chamber, wherein the first fan is located between the wet curtain and the air inlet, and the second fan is located between the wet curtain and the first filter screen.

[0011] Furthermore, the bottom of the explosion-proof cylinder is connected to a dust collection box, and the bottom wall of the dust removal chamber has a dust discharge port that communicates with the dust collection box. The dust discharge port is located at the bottom of the side of the first filter screen away from the air outlet.

[0012] Furthermore, it also includes: a protective net, which is detachably installed at the air outlet.

[0013] Furthermore, the protective net is installed at the air outlet via a plug-in connection.

[0014] Furthermore, the top and bottom walls of the dust removal chamber located at the air outlet are respectively provided with mounting grooves.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The dust removal equipment for preventing dust explosion provided by this utility model involves gas entering through the air inlet and first coming into contact with the water curtain formed by the cleaning water inside the wet curtain.

[0028] In this embodiment of the dust removal equipment for preventing dust explosions, after the gas enters through the air inlet 3, it first comes into contact with the water curtain formed by the cleaning water inside the wet curtain 7. The cleaning water adsorbs the combustible dust contained in the gas. The cleaning water flows into the water storage tank 10 for collection, and then filters the combustible dust again through the first filter screen 5. At this time, the content of combustible dust has been greatly reduced, and the accumulation rate of combustible dust on the first filter screen 5 is slower, reducing the number of cleaning times and making it more convenient to use.

[0029] Specific Implementation Method Two: Combining Figure 1 , Figure 2 This embodiment differs from specific embodiment one in that it also includes a delivery pump 11. The inlet of the delivery pump 11 is connected to the water storage tank 10, and the outlet of the delivery pump 11 is connected to the outlet seat 6 through a second drain pipe 12.

The water is filtered using the second filter screen 13, and the clean water can be recycled under the drive of the delivery pump 11, thereby saving water resources and reducing operating costs. Other components and connections are the same as in specific embodiment one.

[0030] Specific implementation method three: Combining Figure 1 This embodiment differs from specific embodiment one in that the air supply mechanism includes a first fan 14 and a second fan 15 installed within the dust removal chamber 2. The first fan 14 is located between the evaporative cooling pad 7 and the air inlet 3, while the second fan 15 is located between the evaporative cooling pad 7 and the first filter screen 5. The first fan 14 and the second fan 15 work together to drive the gas flow, resulting in better gas flow and higher dust removal efficiency. Other components and connections are the same as in specific embodiment one.

The dust collection box 16 can collect the dust on the first filter screen 5, preventing dust diffusion and making the working environment cleaner. Other components and connections are the same as in specific embodiment one.

[0032] Specific Implementation Method Five: Combining Figure 1 This embodiment differs from specific embodiment one in that it also includes a protective net 17, which is detachably installed at the air outlet 4.

Other components and connections are the same as in specific embodiment one.

[0033] Specific Implementation Method Six: Combination Figure 1 This embodiment is identical to the specific embodiment except that the protective net 17 is installed at the air outlet 4 via a plug-in connection. This plug-in installation method eliminates the need for additional tools during installation and removal, making it very convenient and preventing tool loss. Other components and connections are the same as in specific embodiment five.

[0034] Specific implementation method seven: Combination Figure 1 , Figure 4 This embodiment differs from specific embodiment six in that the top and bottom walls of the dust removal chamber 2, located at the air outlet 4, are respectively provided with mounting grooves.

The other components and connections are the same as in Specific Implementation Method Six.

[0035] Specific implementation method eight: Combination Figure 4 This embodiment differs from Specific Embodiment Five in that the protective net 17 is equipped with two symmetrically distributed handles 23, both extending away from the explosion-proof cylinder 1. When installing or removing the protective net 17, simply grasp the handles 23 for easy movement. Other components and connections are the same as in Specific Embodiment Five.
