Description

Technical Field

[0001] The utility model relates to the technical field of air pollution control, and particularly relates to a dust reduction device for air pollution prevention and control. Background Technique

[0002] With the rapid development of the economy, the environmental pollution problems are becoming more and more serious. Excessive dust and pollutants in the air will affect human health. Therefore, in order to reduce the impact of air pollution on the environment and health, it is necessary to carry out dust reduction treatment on the dust in the air.

[0003] The Chinese patent "A dust reduction device for preventing air pollution" with the authorization announcement number "CN 221107536U" atomizes the water drawn into the pipeline by a spray gun and sprays it to the outside. The atomized water combines with the impurities in the air to play a role in dust reduction.

[0004] Although the above application can play a role in dust reduction, when the dust in the air contacts the atomized water during dust reduction, it will form particles and settle to the ground. When the water evaporates, dust will be formed again and lifted up, and the dust reduction effect is not good.

[0005] Therefore, a dust reduction device for air pollution prevention and control is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a dust reduction device for air pollution prevention and control to solve the above problems, and improve the problem that when the dust in the air contacts the atomized water during dust reduction, it will form particles and settle to the ground. When the water evaporates, dust will be formed again and lifted up, and the dust reduction effect is not good.

[0007] The utility model realizes the above purpose through the following technical solutions. A dust reduction device for air pollution prevention and control includes: a control box, a mounting seat is rotatably connected to the top end of the control box, a spray gun is rotatably connected to the inside of the mounting seat, and a dust reduction mechanism is arranged on one side of the control box; wherein, the dust reduction mechanism includes a treatment box fixedly connected to one side of the control box, a fan is installed on one side of the treatment box, a connecting pipe is arranged on the inner wall of the treatment box, one end of the connecting pipe penetrates out of the treatment box and is communicated with a collection box, the other side of the collection box is communicated with a circular pipe, a series of equally distributed dust suction pipes are fixedly connected to the surface of the circular pipe, a baffle is fixedly connected to the upper end of the inner wall of the collection box, and a cleaning component is arranged on the surface of the baffle.

[0008] Preferably, the cleaning assembly includes a motor fixedly connected to the top end of the collection box. The output shaft of the motor penetrates to the inside of the collection box and is fixedly connected with a reciprocating lead screw. A moving rod is arranged on the surface of the reciprocating lead screw. One end of the moving rod is fixedly connected with a cylinder. A round rod is slidably connected to the inner wall of the cylinder. One side of the baffle is slidably connected with a moving plate. One end of the round rod penetrates out of the cylinder and is fixedly connected with one side of the moving plate. The other side of the baffle is slidably connected with a scraper. Two sliders are fixedly connected to the other side of the moving plate. The sliders penetrate through the baffle and are fixedly connected with one side of the scraper. Starting the motor drives the reciprocating lead screw to rotate, so that the moving rod, the cylinder and the round rod move up and down reciprocally, which is beneficial to driving the scraper to move up and down reciprocally to scrape and clean the particles adhered to the surface of the baffle. Under the interaction of the moving plate and the scraper, it is ensured that the scraper always fits the surface of the baffle when moving up and down reciprocally, and the baffle is cleaned to avoid excessive adhesion of particles on the baffle.

[0009] Preferably, one side of the inner wall of the collection box is fixedly connected with a guiding plate, and the surface of the guiding plate is curved in an arc shape.

[0014] The beneficial effects of the present utility model are:

[0015] 1. While the device atomizes and sprays to reduce dust in the air through the spray cannon, it starts the fan to exhaust the air in the treatment box, creating a negative pressure in the treatment box. This is beneficial for the connecting pipe, round pipe, and dust suction pipe to adsorb the particles that have settled after contacting water. The inhaled particles will enter the collection box, which helps reduce the dust content in the air and improves the dust reduction effect. At the same time, when particles, dust, and air enter the collection box, the baffle is used to separate the dust, air, and particles, which is beneficial for retaining the particles in the collection box to complete the collection of the adsorbed particles and prevent the particles from entering the treatment box and mixing with the aqueous solution. This is beneficial for increasing the usage duration of the aqueous solution in the treatment box and thus improving the usage of the device;

[0016] 2. When cleaning the baffle, start the motor to drive the reciprocating screw rod to rotate, so that the moving rod, cylinder, and round rod move up and down reciprocally.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Specifically, when implemented: As Figures 1-5 shown, a dust-removing device for preventing air pollution includes: a control box 1, a mounting seat 4 is rotatably connected to the top end of the control box 1, a spray cannon 2 is rotatably connected to the inside of the mounting seat 4, and a dust-removing mechanism 3 is arranged on one side of the control box 1; wherein, the dust-removing mechanism 3 includes a processing box 31 fixedly connected to one side of the control box 1, a blower 32 is installed on one side of the processing box 31, a connecting pipe 33 is arranged on the inner wall of the processing box 31, one end of the connecting pipe 33 penetrates out of the processing box 31 and is communicated with a collection box 34, the other side of the collection box 34 is communicated with a circular pipe 35, and a series of equally distributed dust suction pipes 36 are fixedly connected to the surface of the circular pipe 35. An upper end of the inner wall of the collection box 34 is fixedly connected with a baffle 37, and a cleaning component 38 is arranged on the surface of the baffle 37. The other end opening of the dust suction pipe 36 is in a flared shape. An included angle is formed between the surface of the baffle 37 and the horizontal plane.

[0025] The fixing method after the mounting seat 4 rotates and the fixing method after the spray cannon 2 rotates are the same as those in the original scheme. A water tank and a high-pressure pump are arranged inside the control box 1. The control box 1, the mounting seat 4 and the spray cannon 2 are combined to form a fog cannon machine in the prior art. Its operating principle during dust removal is to use the high-pressure pump to introduce the water in the water tank into the spray cannon 2 and perform dust removal through atomized spraying by the spray cannon 2.

[0026] The processing box 31 is filled with an aqueous solution. When using this device for dust removal, the blower 32 is started to discharge the air in the processing box 31 to form a negative pressure in the processing box 31. At this time, under the action of the connecting pipe 33 and the circular pipe 35, the dust suction pipe 36 will adsorb the settled particles. During the adsorption process, some dust in the air will be inhaled together with the settled particles. At this time, the dust, particles and air will enter the collection box 34 through the dust suction pipe 36 and the circular pipe 35, and will first contact the baffle 37 under the action of the gas flow direction. The baffle 37 intercepts the adsorbed particles. Among them, some particles will fall on the inner bottom wall of the collection box 34 under the action of their own gravity, and some particles that do not fall adhere to the baffle 37. The baffle 37 separates the inhaled particles, gas and dust. The separated gas and dust enter the processing box 31 through the connecting pipe 33, and the dust is fused with the aqueous solution in the processing box 31.

[0027] As Figure 2 、 Figure 3 、 Figure 4And Figure 5 As shown in Figure 5 , the cleaning component 38 includes a motor 381 fixedly connected to the top end of the collection box 34. The output shaft of the motor 381 penetrates into the inside of the collection box 34 and is fixedly connected with a reciprocating lead screw 382. A moving rod 383 is arranged on the surface of the reciprocating lead screw 382. One end of the moving rod 383 is fixedly connected with a cylinder 384. A round rod 385 is slidably connected to the inner wall of the cylinder 384. One side of a baffle 37 is slidably connected with a moving plate 386. One end of the round rod 385 penetrates out of the cylinder 384 and is fixedly connected with one side of the moving plate 386. The other side of the baffle 37 is slidably connected with a scraper 388. The other side of the moving plate 386 is fixedly connected with two sliders 387. The sliders 387 penetrate through the baffle 37 and are fixedly connected with one side of the scraper 388.

[0028] When cleaning the particles adhered to the surface of the baffle 37, start the motor 381 to drive the reciprocating lead screw 382 to rotate. The reciprocating lead screw is in the form of two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. By the rotation of the reciprocating lead screw, the side of the spiral groove pushes the moving block placed in the spiral groove to make an axial reciprocating motion. Therefore, when the reciprocating lead screw 382 rotates, it will drive the moving rod 383 to move up and down reciprocally, thereby driving the cylinder 384 and the round rod 385 to move up and down reciprocally synchronously, and driving the moving plate 386, the sliders 387 and the scraper 388 to move up and down reciprocally synchronously. During the moving process, the moving plate 386 and the scraper 388 always adhere to the surface of the baffle 37. The surface of the sliders 387 is slidably connected with the inner wall of the baffle 37. The baffle 37 is provided with a chute matching the sliders 387. The scraper 388 moves up and down to clean the surface of the baffle 37.

[0029] As Figure 3 shown in Figure 3 , one side of the inner wall of the collection box 34 is fixedly connected with a guiding plate 39. The surface of the guiding plate 39 is curved in an arc shape. There is a certain gap between the other end of the guiding plate 39 and the inner bottom wall of the collection box 34. When the particles fall due to their own gravity and during the cleaning process, they will fall on the arc surface of the guiding plate 39 and slide down to the inner bottom wall of the collection box 34 under the action of the arc surface.

[0030] As Figure 4 and Figure 5 shown in Figure 5 , one side of the scraper 388 adheres to the other side of the baffle 37. An angle is formed between the top end of the scraper 388 and the horizontal plane. When the scraper 388 moves up for cleaning, the cleaned particles will gather on the inclined plane at the top end of the scraper 388 and fall under the action of the inclined plane at the top end.

[0031] As Figure 2 and Figure 3As shown, an angle is formed between the bottom end of the collection box 34 and the horizontal plane, and the guiding plate 39 is arranged above the lower end of the inner bottom wall of the collection box 34. When the particles fall on the inner bottom wall of the collection box 34, they will enter the lower end of the inner bottom wall of the collection box 34 under the action of the inclined plane of the inner bottom wall of the collection box 34.

[0032] When the present utility model is in use and dust is removed from the air, the high-pressure pump is started through the controller to introduce the water in the water tank inside the control box 1 into the spray cannon 2, and the water is atomized and sprayed through the spray cannon 2 for dust removal. At the same time, the fan 32 is started to discharge the air in the treatment box 31, so that a negative pressure is formed in the treatment box 31. At this time, under the action of the connecting pipe 33 and the circular pipe 35, the dust suction pipe 36 will adsorb the settled particles. During the adsorption process, some dust in the air and the settled particles will be inhaled together. At this time, the dust, particles and air will enter the collection box 34 through the dust suction pipe 36 and the circular pipe 35, and will first contact the baffle 37 under the action of the gas flow direction. The baffle 37 intercepts the adsorbed particles. Among them, some particles will fall on the inner bottom wall of the collection box 34 under the action of their own gravity, and some particles that do not fall adhere to the baffle 37. The baffle 37 separates the inhaled particles, dust and gas. The separated gas and dust enter the treatment box 31 through the connecting pipe 33, and the dust is fused with the aqueous solution in the treatment box 31.

[0033] When cleaning the particles adhering to the surface of the baffle 37, the motor 381 is started to drive the reciprocating lead screw 382 to rotate, so that the moving rod 383 drives the cylinder 384, the round rod 385, the moving plate 386, the slider 387 and the scraper 388 to move up and down reciprocally. During the moving process, the scraper 388 cleans the surface of the baffle 37. The particles that fall off during the cleaning and the particles that fall due to their own gravity will fall on the guiding plate 39, and slide down to the inner bottom wall of the collection box 34 under the action of the arc surface of the guiding plate 39, and enter the lower end of the inner bottom wall of the collection box 34.

[0034] It should be noted that in the above description, the high-pressure pump, the motor 381 and the fan 32 are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the high-pressure pump, the motor 381 and the fan 32 can be powered by an internal power supply or by the mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard this specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
