DETAILED DESCRIPTION

[0021] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0022] The dust treatment device for construction described in this embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a box body 1 for storing water. The box body 1 is a sealed rectangular structure. A partition 12 is horizontally fixed in the box body 1. The partition 12 is a rectangular block. The partition 12 divides the box body 1 into two upper and lower areas. The box body 1 below the partition 12 is used for storing water.

[0023] The box body 1 above the partition 12 is installed with a negative pressure pump 11, which is an existing negative pressure vacuum pump, including an air intake nozzle and an exhaust nozzle for exhaust. A battery can be installed in the box body 1 above the partition 12, and the negative pressure pump 11 is powered by the battery. The negative pressure pump 11 can also be powered by a power supply indoors or outdoors or a generator. A first through hole is opened on the side wall of the box body 1 above the partition 12, and the exhaust nozzle of the negative pressure pump 11 is connected to the first through hole; a second through hole is opened on the partition 12, which is connected from top to bottom, and the air intake nozzle of the negative pressure pump 11 is connected to the second through hole;

[0024] A fixed block 3 is vertically fixed to the bottom of the partition 12. The width of the fixed block 3 is consistent with the width of the partition 12, that is, consistent with the distance between the front and rear inner walls of the box body 1. The second through hole and the first connecting pipe 6 are respectively located on the left and right sides of the fixed block 3. The negative pressure pump 11 is located on the left side of the fixed block 3. The first connecting pipe 6 and the dust suction port 4 are located on the right side of the fixed block 3. The fixed block 3 is provided with mounting holes that are connected to the left and right. A filter screen 2 is installed in the mounting hole. The filter screen 2 blocks dust and allows air to flow through. Of course, in actual use, the filter assembly can also be a filter screen with a groove-shaped structure with the notch facing upward, and the first through hole is located at the top of the filter screen with the groove-shaped structure. This paragraph of text as a whole constitutes a filter assembly that prevents dust from entering the second through hole;

[0025] The above two paragraphs as a whole constitute a negative pressure mechanism for generating negative pressure in the box body 1 below the partition 12. Negative pressure is generated in the box body 1 below the partition 12 through the negative pressure pump 11. After the dust enters the box body 1 below the partition 12 from the dust suction port 4, it will be blocked by the filter 2, which can prevent the dust from entering the second through hole, so that the dust stays in the box body 1 on the right side of the filter 2 and falls into the water after accumulation. Of course, in actual use, the negative pressure mechanism can also be a negative pressure fan, which generates negative pressure in the box body 1 below the partition 12.

[0026] The filter 2 is a washable dustproof filter, such as a HWN washable nylon filter or an air-conditioning dustproof nylon filter. After the filter 2 has been used for a period of time, it can be cleaned with water, which is relatively convenient to clean.

[0027] The box body 1 is provided with a water inlet hole for injecting water into the box body 1 below the partition 12, and a drainage hole is provided at the bottom of the box body 1. A first hole cover 14 is provided corresponding to the drainage hole to seal it. The first hole cover 14 and the drainage hole are threadedly matched. Of course, the structure of the first hole cover 14 and the drainage hole can also be the structure of an existing manhole and a manhole cover.

[0028] A third through hole connected up and down is provided on the partition 12 at the top of the fixed block 3, and the water inlet is set at the top of the box body 1. The water inlet is connected to the third through hole through the second connecting pipe 7. A fourth through hole for connecting the fourth through hole and the mounting hole is provided on the fixed block 3, and a second hole cover 8 for sealing the corresponding water inlet is provided. The second hole cover 8 can seal the water inlet. When negative pressure is generated in the box body 1 below the partition 12, negative pressure can be prevented from being generated in the water inlet, thereby preventing dust from entering the water inlet. When water is injected into the box body 1 below the partition 12, the water flow will flow to the filter screen 2 through the second connecting pipe 7, the third through hole and the fourth through hole, so that the filter screen 2 can be cleaned, which is more convenient. In addition, during use, the filter screen 2 can be cleaned by injecting water into the box body 1, and the filter screen 2 does not need to be disassembled, which is more convenient.

[0029] The first hole cover 14 is located at the bottom of the left side wall of the box body 1. The inner bottom surface of the box body 1 is an inclined surface with the left side lower and the right side higher, so that the water and dust in the box body 1 can flow to the left side of the box body 1, making it easier for water to flow out of the drainage hole and reducing the mixture of water and dust remaining in the box body 1.

[0030] A dust suction port 4 is provided on the outside of the box body 1, and the dust suction port 4 is fixed to the left side wall of the box body 1 above the partition 12. A sixth through hole communicating with the left and right is opened on the left side wall of the box body 1. The dust suction port 4 is fixed to the sixth through hole and connected to the sixth through hole. The dust suction port 4 is trumpet-shaped, which can increase the contact area between the dust suction port 4 and the dust, so that the dust can more easily enter the dust suction port 4. The dust suction port 4 is connected to the box body 1 below the partition 12 through a first connecting pipe 6. The first connecting pipe 6 includes a vertically arranged tube and a horizontally arranged tube. A seventh through hole communicating with the upper and lower parts is opened on the partition 12. The vertically arranged tube and the seventh through hole are connected to each other. The dust suction port 4 is connected to the box body 1 below the partition 12 through the first connecting pipe 6.

[0031] A stirring shaft 9 is vertically arranged in the box body 1, and a fifth through hole is opened on the partition 12 for the top end of the stirring shaft 9 to pass through. The top end of the stirring shaft 9 passes through the fifth through hole and is located above the partition 12. A sealing ring 10 is arranged between the stirring shaft 9 and the fifth through hole. The sealing ring 10 is a rotary dynamic seal, which can seal between the stirring shaft 9 and the fifth through hole, so as to better generate negative pressure in the box body 1 below the partition 12. A motor (a driving part for driving the stirring shaft 9 to rotate) is arranged in the box body 1 above the partition 12. The motor is connected to the stirring shaft 9 through a coupling. Of course, in actual use, in order to facilitate the heat dissipation of the motor, a fifth through hole is opened on the top of the box body 1 for the top end of the stirring shaft 9 to pass through. Eight through holes, the motor is installed on the top of the box 1, the top of the stirring shaft 9 passes through the eighth through hole and is connected to the motor, and a first fixed rod 16 is fixed horizontally on the stirring shaft 9 below the partition 12. The stirring shaft 9 is driven by the motor to rotate, so that the stirring shaft 9 drives the first fixed rod 16 to rotate, thereby stirring the water in the box 1, which can prevent dust from floating on the water surface and increase the adsorption effect of water on dust. Secondly, during discharge, the sediment can be stirred, thereby reducing the accumulation of sediment in the box 1 and reducing the accumulation of sediment in the box 1; of course, in actual use, a handle can also be fixed on the top of the stirring shaft 9, and the stirring shaft 9 can be manually rotated by the handle. This paragraph of text as a whole constitutes a stirring assembly for stirring water.

[0032] Two first fixing rods 16 are provided, and the two first fixing rods 16 are located at the same horizontal height, and the two first fixing rods 16 are symmetrically distributed left and right. A second fixing rod 13 is vertically fixed to the top of one end of the first fixing rod 16 away from the stirring shaft 9, a second fixing rod 13 is vertically fixed to the top of the left end of the left first fixing rod 16, and a second fixing rod 13 is vertically fixed to the top of the right end of the right first fixing rod 16. The horizontal height of the top of the second fixing rod 13 is lower than the horizontal height of the bottom end of the fixed block 3. When the stirring shaft 9 drives the first fixing rod 16 and the second fixing rod 13 to rotate, the second fixing rod 13 will not collide with the fixed block 3, and the stirring effect can be increased by the second fixing rod 13.

[0033] Four rollers 15 (mobile components for facilitating the movement of the box 1) are arranged at the bottom of the box 1, and the four rollers 15 are evenly installed at the four corners of the bottom of the box 1. The rollers 15 are universal wheels with a self-locking function. Of course, in actual use, the mobile component can also be an existing crawler-type walking mechanism, which is composed of a chassis, a crawler device, and a walking transmission system. The box 1 is fixed on the chassis, and a hose 5 is arranged between the dust suction port 4 and the first connecting pipe 6. The hose 5 is relatively long and is made of flexible material, such as PVC or rubber, and can be bent. In this way, a worker can hold the hose 5 to move the dust suction port 4, so that the dust suction port 4 can absorb the accumulated dust.

[0034] A fixed scissor lift is provided at the bottom of the box 1. The fixed scissor lift is a known technology. The main structure of the fixed scissor lift includes an upper plate and a lower plate. A scissor arm, a pulley, a hinge support, and a lifting hydraulic cylinder are provided between the upper plate and the lower plate. A roller for moving the scissor arm is installed at the bottom of the lower plate. The upper plate is fixed to the bottom of the box 1. The scissor arm is driven up and down by the telescopic lifting hydraulic cylinder, so that the box 1 moves up and down. In this way, the box 1 can be located at a high place and absorb higher dust, which is more convenient. This paragraph of text as a whole constitutes a lifting mechanism for adjusting the horizontal height of the box 1. Of course, in actual use, the lifting mechanism can also include a fixed plate provided under the box 1, a hydraulic cylinder is provided between the fixed plate and the box 1, the cylinder barrel of the hydraulic cylinder is vertically fixedly installed on the top of the fixed plate, the piston rod of the hydraulic cylinder is fixed to the bottom of the box 1, and the box 1 moves up and down through the telescopic movement of the piston rod of the hydraulic cylinder.

[0035] Working principle:

[0036] When in use, the box body 1 is moved to the construction site, such as indoor construction, and then water is injected into the box body 1 below the partition 12 through the water inlet hole, so that the water in the box body 1 below the partition 12 overflows the bottom of the fixed block 3, and then a negative pressure is generated in the box body 1 below the partition 12 through the negative pressure pump 11. Because the dust suction port 4 is connected to the box body 1 below the partition 12 through the first connecting pipe 6, a negative pressure is also generated in the dust suction port 4, so that the external dust enters the box body 1 below the partition 12 from the dust suction port 4, and then is blocked and filtered by the filter 2, and a part of it will fall into the water. Moreover, when in use, after a period of use, the negative pressure pump 11 can be turned off to make the dust on the filter 2 fall into the water. At the same time, the first fixed rod 16 and the second fixed rod 13 can be driven to rotate by the stirring shaft 9 to make the water in the box body 1 shake. First, the filter 2 can be cleaned, and second, In order to mix the dust and water and reduce the dust floating on the water surface, of course, water can be injected into the box body 1 through the water inlet, so that the water flow can flush the filter screen 2, and the dust can be sucked into the box body 1 through the dust suction port 4, so that mud and dirt can be prevented from being generated on the indoor floor, which is convenient for construction. After the construction is completed, the drainage hole can be opened through the first hole cover 14, and the dust and water in the box body 1 can be discharged and cleaned through the drainage hole. At the same time, the first fixed rod 16 and the second fixed rod 13 are driven to rotate by the stirring shaft 9, so that the dust and water are mixed and discharged, which can reduce the accumulation of sediment in the box body 1 below the partition 12; when the box body 1 is cleaned or used for the next time, when water is injected into the box body 1 below the partition 12 through the water inlet, the water flow will clean the filter screen 2, so that the box body 1 can be cleaned or the filter screen 2 can be cleaned at the same time of water injection, which is more convenient.
