[0002] During the construction process, a large amount of construction materials such as sand, gravel, and square materials are needed. During the construction process, the transportation, dumping, and use of construction materials are likely to generate a large amount of dust, causing dust to fly in the construction site. The bodies, chassis, and wheels of engineering vehicles entering and leaving the construction site will be covered with a large amount of dust. If the vehicles entering and leaving the construction site are not cleaned, the vehicles will bring dust and mud out of the construction site, which will easily cause the road surface outside the construction site to be dirty. The mud and dust dropped by the vehicles during driving not only affect the appearance of the city, but also easily form dust, which will seriously affect the living environment and health of residents along the surrounding areas.

[0003] At present, car washers are mostly used to wash construction vehicles to avoid air pollution caused by dust from construction vehicles. A large amount of mud, sand and dust will be generated during the washing process. The mud, sand and dust washed out will fall into the recovery box under the action of gravity. The mud, sand and dust and other impurities will directly contact the filter plate, causing the filter plate to be blocked, affecting the recycling of the aqueous solution. In addition, when the car wash machine is not used daily, external impurities are easily in direct contact with the nozzle under the action of gravity, affecting the normal use of the car wash machine.

[0024] Combine the following Figure 1-Figure 9 The dust suppression device for use in building construction of the present invention is described.

[0025] In one embodiment, a dust suppression device for building construction includes: A recycling box 100 and a grille 200, wherein the grille 200 is disposed at the top of the recycling box 100; The spray mechanism 300 includes a water tank 310, a plurality of first spray pipes 313 and a pedal 320 arranged in the recovery tank 100. A first delivery pump 311 is arranged at the top of the water tank 310. A multi-way pipe 312 is arranged between the first delivery pump 311 and the plurality of first spray pipes 313. A coil spring 322 is arranged between the plurality of first spray pipes 313 and the grille 200. An L-shaped plate 323 is fixedly connected to the bottom end of the grille 200. A first spring 324 is fixedly connected between the L-shaped plate 323 and the pedal 320. A trigger plate 321 is fixedly connected to the surface of the first spray pipe 313. A push rod in contact with the trigger plate 321 is fixedly connected to the bottom end of the pedal 320. The filtering mechanism 400 includes a plurality of rollers 410 rotatably connected to the recycling box 100 and a motor 412 fixedly mounted on the recycling box 100. Flexible filter cloths 411 are provided on the surfaces of the plurality of rollers 410. The number of the rollers 410 is nine. The output shaft of the motor 412 is fixedly connected to one end of one of the rollers 410 below to perform flow filtration on the mixed solution after flushing the engineering vehicle.

[0026] It should be noted that the recovery box 100 is set in the ground, and the grille 200 is parallel to the ground. At the same time, the device needs to be set at the entrance and exit of the construction site to facilitate spraying and dust reduction of construction vehicles.

[0027] like Figure 2 and Fig. 9 As shown, a second delivery pump 440 is provided at the top of the water tank 310, a suspension plate 441 is provided in the recovery box 100, a return pipe 442 is provided between the second delivery pump 440 and the suspension plate 441, one end of the return pipe 442 passes through the suspension plate 441 and is provided with a liquid suction head, and limiting rods 443 are provided at the four corners of the top of the suspension plate 441, and the bottom end of the limiting rod 443 passes through the suspension plate 441.

[0028] A filter plate 444 is provided in the water tank 310, and the filter plate 444 is ridge-shaped as a whole, and the liquid extraction pipe of the first delivery pump 311 sequentially passes through the water tank 310 and the filter plate 444. The ridge-shaped filter plate 444 divides the water tank 310 into two parts, and any impurities will stay on both sides of the top of the filter plate 444, ensuring that the first delivery pump 311 will not be blocked, and at the same time, the recovered solution is isolated and used after filtering, reducing the risk of device blockage.

[0029] In this embodiment, the second delivery pump 440 is started, and the aqueous solution in the recovery box 100 will reach the upper surface of the filter plate 444 after passing through the reflux pipe 442. After being filtered through the filter plate 444, the aqueous solution reaches the lower area of ​​the water tank 310 for recycling. At the same time, the recovered aqueous solution in the recovery box 100 can be used after sedimentation, and the mud mixed in the aqueous solution can be removed. The suspension plate 441 will float on the liquid surface. When the aqueous solution is recovered, the mud is prevented from clogging the liquid suction head. At the same time, the limit rod 443 can play a stabilizing role. The distance between the limit rod 443 and the suspension plate 441 provides space for the liquid suction head. As for whether the recovered aqueous solution is used or not, it can be adjusted according to actual conditions.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the spray mechanism 300 also includes an electric push rod 331 fixedly connected to the top of the grille 200, and the top of the electric push rod 331 is fixedly connected to a side plate 330, and the opposite sides of the two side plates 330 are provided with a second spray pipe 333 connected to the multi-way pipe 312.

[0031] The top of the grille 200 is fixedly connected with a first connecting rod 332, the top of the first connecting rod 332 is plugged with a second connecting rod 334, the top of the second connecting rod 334 is fixedly connected with the side plate 330, and part of the multi-way pipe 312 sequentially passes through the first connecting rod 332 and the second connecting rod 334. The electric push rod 331 is more stable when adjusting the height of the side plate 330, and it can provide installation space for the multi-way pipe 312 to prevent the multi-way pipe 312 from being exposed to the outside and affected by the external environment, thereby ensuring the normal operation of the spray dust reduction operation.

[0032] In this embodiment, after the engineering vehicle is in place, the electric push rod 331 is started, and the height of the side panel 330 is adjusted by the electric push rod 331, so that the second spray pipe 333 is more suitable for the engineering vehicle, thereby improving the dust reduction effect on the engineering vehicle. At the same time, it can also be adjusted during flushing, thereby changing the spraying route of the second spray pipe 333 and improving the dust reduction effect.

[0033] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the filtering mechanism 400 also includes two fixed plates 430 fixedly connected to the recovery box 100, and the opposite sides of the two fixed plates 430 are fixedly connected to second springs 431, and one end of the second spring 431 away from the fixed plate 430 is fixedly connected to a cleaning plate 432 that is in close contact with the flexible filter cloth 411.

[0034] The inner bottom wall of the recycling box 100 is fixedly connected with two guide plates 110, and the cross section of the guide plate 110 is a right-angled trapezoid. Under the guidance of the inclined surface of the guide plate 110 with a right-angled trapezoidal cross section, impurities will be better gathered on the side of the recycling box 100, which is convenient for better cleaning and maintenance in the later stage.

[0035] Isolation plates 120 are fixedly connected to both sides of the inner wall of the recovery box 100. A sludge pump 130 is provided at the top of the recovery box 100. The sludge pump 130 passes through the recovery box 100 and the isolation plate 120 in sequence. The isolation plate 120 can isolate larger stones, and the sludge falls to the side of the recovery box 100. The sludge pump 130 is used to regularly extract the sludge, which reduces the difficulty of later maintenance of the device. An inclined flushing pipe 420 is provided on one side of the inner wall of the recovery box 100, and the flushing pipe 420 is connected to the multi-way pipe 312. The flushing pipe 420 can cooperate with the cleaning plate 432 to ensure the filtering performance of the flexible filter cloth 411 and always maintain efficient filtering.

[0036] The flexible filter cloth 411 is ridge-shaped as a whole, and a resistance-increasing layer is provided on the surface of the round roller 410, and the resistance-increasing layer is a rubber material component. The resistance-increasing layer can increase the friction between the round roller 410 and the flexible filter cloth 411, ensuring the normal rotation of the flexible filter cloth 411 without idling, and the ridge-shaped flexible filter cloth 411 can better guide impurities.

[0037] In this embodiment, the motor 412 is started, and the rotation of one of the round rollers 410 is utilized to drive the entire flexible filter cloth 411 to rotate. During the rotation of the flexible filter cloth 411, impurities will be cleaned to the side of the recovery box 100. When the flexible filter cloth 411 rotates, the cleaning plate 432 can scrape and clean the flexible filter cloth 411. At the same time, the second spring 431 can maintain the tension of the flexible filter cloth 411 to ensure the normal operation of the flexible filter cloth 411.

[0038] Working principle: When the device is in use, the tires of the engineering vehicle will contact the two pedals 320. Under the action of the gravity of the engineering vehicle, the pedals 320 will fit with the grille 200. When the pedals 320 are lowered, the push rod will push the trigger plate 321, driving the first spray pipe 313 to rotate, and the coil spring 322 is in a force-reeling state. The nozzle on the first spray pipe 313 is in a vertical state. After the engineering vehicle stops in place, the first delivery pump 311 is started, and the aqueous solution in the water tank 310 will be sprayed out of the first spray pipe 313 to spray and reduce dust on the bottom of the engineering vehicle. Part of the aqueous solution will enter the second spray pipe 333 to spray the side of the engineering vehicle. Spraying is performed to reduce dust, and the spraying paths of the first spray pipe 313 and the second spray pipe 333 are crisscrossed. The mixed solution generated by the spraying will fall from the intervals of the grille 200 into the recovery box 100 under the action of gravity, and the falling mixture will reach the surface of the filter mechanism 400. The motor 412 is started, and the rotation of one of the round rollers 410 is used to drive the rotation of the entire flexible filter cloth 411. During the rotation of the flexible filter cloth 411, impurities will be cleaned to the side of the recovery box 100, and the aqueous solution will pass through the flexible filter cloth 411 and reach the bottom of the middle part of the recovery box 100, completing the recycling of the aqueous solution and realizing the dust reduction operation for the engineering vehicles.

[0039] It should be noted that the sludge pump 130, the first delivery pump 311, the multi-way pipe 312, the first spray pipe 313, the coil spring 322, the electric push rod 331, the second spray pipe 333, the flexible filter cloth 411, the motor 412, the flushing pipe 420, the second delivery pump 440, the suspension plate 441, etc. in the above description are all devices with relatively mature application of existing technologies. The specific model can be selected according to actual needs. At the same time, the power supply of the sludge pump 130, the first delivery pump 311, the electric push rod 331, the motor 412 and the second delivery pump 440 can be a built-in power supply. Power supply can also be AC ​​power supply, and the specific power supply method is selected according to the situation. Among them, the surfaces of the first spray pipe 313, the flushing pipe 420 and the second spray pipe 333 are all provided with multiple nozzles, which are common components in this field. At the same time, the port setting of the multi-way pipe 312 needs to be adapted according to the number of the first spray pipe 313, the flushing pipe 420 and the second spray pipe 333 that need to be connected. The surface of the flexible filter cloth 411 presents multiple filter holes, and its own material is similar to a conveyor belt, so when the round roller 410 is running, it can rotate normally, which will not be elaborated here.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
