[0025] like Figure 1-4 As shown, the utility model provides a technical solution:

[0026] A dust removal device for a powder injection pile ash conveying tank comprises a tank body 1, a first filter screen 2 is arranged inside the tank body 1, the first filter screen 2 divides the tank body 1 into an upper and lower part, a discharge port 19 is arranged at the bottom of the tank body 1 below the first filter screen 2, a feed port 4 is arranged on the side wall of the tank body 1 below the first filter screen 2, a fan 3 is arranged on the first filter screen 2, the fan 3 is used to blow air to the upper part of the tank body 1, the fan 3 can be wirelessly controlled, and the wind speed of the fan 3 is adjustable, an exhaust hole 5 is arranged on the tank body 1 above the first filter screen 2, the exhaust hole 5 is connected to a purification box 6 arranged outside the tank body 1, an air outlet 18 is arranged on a side of the purification box 6 away from the exhaust hole 5, the air outlet 18 is connected to the outside air, a filter assembly is arranged in the purification box 6, and a filter bag assembly is arranged on the top of the tank body 1.

[0027] In this embodiment, a water tank 10 is arranged on one side outside the purification box 6, and water is pre-stored in the water tank 10. One side of the water tank 10 is connected to the top of the purification box 6 through a water inlet pipe 11, and the other side of the water tank 10 is connected to the bottom of the purification box 6 through a return pipe 13, which is used to form a circulating water circulation path together with the purification box 6, thereby improving the practicability of the device.

[0028] In this embodiment, an inlet pump 12 is provided at one end of the water inlet pipe 11 close to the water tank 10, and a return pump 14 is provided at one end of the return pipe 13 close to the water tank 10. The inlet pump 12 is used to pump out the water in the water tank 10, and the return pump 14 is used to replenish circulating water into the water tank 10, thereby improving the efficiency of water circulation in the device.

[0029] In this embodiment, the filter assembly includes a nozzle 9, a second filter screen 7 and an activated carbon screen 8. The nozzle 9 is arranged at the top of the purification box 6, and the nozzle 9 is connected to the water inlet pipe 11 for spraying water into the purification box 6. The second filter screen 7 is arranged in the purification box 6 and is located below the exhaust hole 5 and the exhaust hole 18. The activated carbon screen 8 is arranged in the purification box 6 and is located below the second filter screen 7 to filter and deodorize the water that falls after adsorbing dust, thereby improving the practicability of the device.

[0030] In another embodiment, the second filter screen 7 and the activated carbon screen 8 can be replaced with other filter layers for water purification according to the needs of the construction site, so that the purified water does not affect the use of water circulation. This setting can be a conventional setting in the field of water purification, which improves the economy of the device.

[0031] In this embodiment, the filter bag assembly includes a power member 15, a mounting frame 16 and a filter bag 17. The power member 15 can be an electric push cylinder or a vibration motor, which is arranged on the top of the tank body 1. The output end of the power member 15 is connected to the mounting frame 16 to drive the mounting frame 16 to move. The mounting frame 16 is hollow inside and an inner cavity is arranged. A plurality of filter bags 17 are arranged on the mounting frame 16, and the interior of the filter bags 17 are connected to the inner cavity of the mounting frame 16. One side of the mounting frame 16 is open, and the opening is connected to the exhaust hole 5 through a flexible tube. The power member 15 is used to shake off the dust layer adsorbed on the outer layer of the filter bag 17 to improve the air circulation efficiency. The flexible tube avoids air circulation difficulties when the mounting frame 16 moves, thereby improving the practicability of the device.

[0032] In another embodiment, the mesh size of the first filter 2 is smaller than the mesh size of the filter bag 17, that is, the size of the mesh on the first filter 2 is larger than the size of the mesh on the filter bag 17, so that the first filter 2 filters out large dust particles, the filter bag 17 filters out medium dust particles, and the water sprayed by the nozzle 9 absorbs small dust particles, thereby avoiding the problem of easy clogging of the single-layer filter layer and improving the efficiency of the device.

[0033] In this embodiment, the end of the feed port 4 away from the tank body 1 is configured as a funnel-shaped inlet, and the bottom of the tank body 1 is also configured as a funnel-shaped inlet to facilitate the introduction and export of powder materials, thereby improving the efficiency of the device.

[0034] In another embodiment, the first filter screen 2, the filter bag assembly and the filter assembly are all configured to be detachable, and observation ports are provided on the side walls or the top of the tank body 1 and the purification box 6 to facilitate the inspection or replacement of parts of the device. When the device is in use, the observation port can be sealed by a cover to avoid affecting the use of the device. This setting is a conventional setting in the field and improves the practicability and economy of the use of the device.

[0035] Working principle: First, start the fan 3, and introduce the powder into the tank body 1 through the feed port 4 to avoid the formation of negative pressure in the tank body 1 due to the entry of the powder. The powder falls to the bottom of the tank body 1 under the action of gravity and is discharged through the discharge port 19; the dust splashed by the powder falling into the tank body 1 mixes with the air in the tank body 1, and under the action of the wind force of the fan 3, the large dust particles are initially filtered through the first filter screen 2, and then enter the upper part of the tank body 1. Under the secondary filtration of several filter bags, the air enters the purification box 6 through the inner cavity of the mounting frame 16, the flexible pipe and the exhaust hole 5; then start the water inlet pump 12 and the return water pump 14, and spray water mist on the air in the purification box 6 through the nozzle 9 to absorb the air. The tiny dust remaining in the air is discharged from the device through the air outlet 18 after being adsorbed by the water mist; the water mist that has adsorbed the tiny dust falls onto the second filter screen 7 under the action of gravity, and accumulates and is filtered on the second filter screen 7 and then falls onto the activated carbon screen 8 below. The water filtered by the activated carbon screen 8 after adsorbing odors and the like is accumulated at the bottom of the purification box 6, and returns to the water tank 10 through the return pipe 13 and the return pump 14, so as to realize the recycling of water resources; after the device has been working for a period of time, the power part 15 is started, so that the output end of the power part 15 drives the mounting frame 16 and the filter bag 17 to shake as a whole, so as to shake off a layer of dust attached to the outside of the filter bag 17, thereby enhancing the air permeability and improving the efficiency of the device.
