Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to an environmentally friendly dust removal device for an environmentally friendly vibrating screen. Background Technology

[0002] A vibrating screen works by utilizing the reciprocating rotary vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two factors results in a complex rotary vibration of the screen surface. The vibration trajectory is a complex spatial curve. The projection of this curve onto the horizontal plane is a circle, while its projection onto the vertical plane is an ellipse. Adjusting the excitation force of the upper and lower rotating weights can change the amplitude, while adjusting the spatial phase angle of the upper and lower weights can change the shape of the screen surface's motion trajectory and thus change the motion trajectory of the material on the screen surface.

[0003] Existing vibrating screens lack dust removal capabilities, causing a large amount of dust to be released into the environment during use. This results in environmentally unfriendly operation of the vibrating screens and significantly reduces their practicality. Utility Model Content

[0004] To solve the above-mentioned technical problems, an environmentally friendly dust removal device for an environmentally friendly vibrating screen is provided. This technical solution solves the problem mentioned in the background art that the existing vibrating screens do not have a dust removal function during use, causing a large amount of dust to be dispersed into the external environment during use, resulting in the problem of the vibrating screen being environmentally unfriendly and greatly reducing its practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An environmentally friendly dust removal device for an environmentally friendly vibrating screen includes a dustproof box, a feeding mechanism at the top of the dustproof box, a screening mechanism at the top of the interior of the dustproof box, and a dust removal mechanism on the left side of the dustproof box. The dust removal mechanism includes a dust pump, with dust inlet pipes connecting the front and rear sides of the dust pump to dust suction heads. Two sets of dust suction heads are installed on the inner walls of the front and rear sides of the dust box. The left side of the dust pump is connected to a dust discharge head through a dust discharge pipe that passes through the rear side of the dust box. The dust discharge head is located at the top of the dust box. Four sets of flow equalization plates are installed on the inner wall of the dust box, and the four sets of flow equalization plates are symmetrically arranged vertically. A high-pressure atomizing nozzle is installed on the left inner wall of the dust box.

Detailed Implementation

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figures 1-4 As shown, an environmentally friendly dust removal device for an environmentally friendly vibrating screen includes a dustproof box 1. A feeding mechanism 2 is located at the top of the dustproof box 1, and a screening mechanism 3 is located at the top inside the dustproof box 1. A dust removal mechanism 4 is located on the left side of the dustproof box 1. The dust removal mechanism 4 includes a dust suction pump 401. Both the front and rear sides of the dust suction pump 401 are connected to dust suction heads 403 via dust inlet pipes 402. Two sets of dust suction heads 403 are located on the inner walls of the front and rear sides of the dustproof box 1. The left side of the dust suction pump 401 is connected to a dust discharge head 406 via a dust discharge pipe 404 that passes through the rear side of the dust removal box 405. The dust discharge head 406 is located within the dust removal box 405. At the top of the dust collector 405, the inner wall of the dust collector 405 is provided with a flow equalization plate 407. There are four sets of flow equalization plates 407, which are arranged symmetrically at the top and bottom. The inner wall of the left side of the dust collector 405 is provided with a high-pressure atomizing nozzle 408. There are two sets of high-pressure atomizing nozzles 408. Both sets of high-pressure atomizing nozzles 408 are connected to the main pipe 410 through branch pipes 409. The other end of the main pipe 410 is connected to the liquid outlet of the liquid pump 411. The liquid inlet of the liquid pump 411 is connected to the liquid tank 412. The liquid tank 412 is located at the top of the dust collector 405, and the liquid pump 411 is located at the top of the liquid tank 412.

[0015] In this scheme, the airflow is driven by the dust pump 401, and the dust is collected by two sets of dust suction heads 403, realizing the efficient suction of dust and sending it into the dust collection box 405 for centralized treatment. The dust outlet head 406 delivers dust-laden gas into the dust collection box 405. The liquid in the liquid tank 412 is delivered by the liquid pump 411 through two sets of high-pressure atomizing nozzles 408 set in the dust collection box 405 and sprayed out in the form of atomization. The airflow distribution is uniformly adjusted and the speed is controlled by the multi-layer symmetrical arrangement of the flow equalization plate 407, which improves the overall treatment efficiency of the dust collection area and achieves full mixing with the atomized droplets, further improving the removal effect of particulate matter. Finally, it can be discharged through the sewage pipe set on the left side of the dust collection box 405.

[0016] Reference Figure 4 As shown, the screening mechanism 3 includes support columns 301, and four sets of support columns 301 are provided. The top ends of the four sets of support columns 301 are fixedly connected to the feed plate 303 by springs 302. The top end of the feed plate 303 is provided with a screen plate 304. The right side of the top end of the screen plate 304 is provided with a slag guide plate 305. The bottom left end of the feed plate 303 is provided with a vibration motor 306.

[0017] In this solution, a vibration motor 306 is installed to generate high-frequency excitation force, which realizes the continuous jumping and screening movement of materials, effectively improving the screen throughput and processing efficiency. In conjunction with the spring 302, the support column 301 and the feed plate 303 are connected, realizing the elastic vibration and buffering effect of the screen plate 304. The guide plate 305 is inclined and set on one side of the screen plate 304 to realize the automatic guidance and collection discharge of coarse materials on the screen. The screen plate 304 is arranged in a plane above the feed plate 303 to realize the grading of materials.

[0018] Reference Figure 2 As shown, the feeding mechanism 2 includes a support frame 201. A feeding pipe 202 is provided at the top of the support frame 201. A feeding port 203 is provided on the outer right side of the feeding pipe 202. A threaded feeding rod 204 is rotatably installed inside the feeding pipe 202. The left end of the threaded feeding rod 204 is fixedly installed at the output end of the first motor 205. The left side of the feeding pipe 202 is connected to the crushing box 207 through a connecting pipe 206. A crushing rod 208 is rotatably installed inside the crushing box 207. Two sets of crushing rods 208 are provided. Gears 209 are fixedly installed on the front side of both sets of crushing rods 208. The two sets of gears 209 mesh with each other. The front side of one set of gears 209 is fixedly installed at the output end of the second motor 210. An inclined plate 211 is provided inside the crushing box 207 away from the two sets of crushing rods 208.

[0019] In this scheme, the first motor 205 directly drives the threaded conveyor rod 204 to rotate, thereby achieving stable control and adjustability of the feeding speed and realizing the uniform conveying effect of material from the feed inlet 203 to the crushing box 207. By setting up intermeshing gears 209, the second motor 210 drives one set of gears 209 to make the two sets of crushing rods 208 rotate in opposite directions, thereby realizing the initial crushing and particle size control of the material. Furthermore, by setting up an inclined plate 211, which is inclinedly arranged inside the crushing box 207, the crushed material is guided and collected for outflow.

[0020] The working principle of this utility model is as follows: In use, firstly, the first motor 205 drives the threaded conveyor rod 204 to rotate, quantitatively conveying the material from the feed inlet 203 to the crushing box 207. Secondly, the second motor 210, through gear 209, drives the two sets of crushing rods 208 to rotate in opposite directions, crushing the material. The crushed material is collected by the inclined plate 211 and then enters the screening process. Next, when the material falls onto the surface of the screen plate 304, the high-frequency vibration force generated by the vibrating motor 306 is transmitted to the screen plate 304, causing the material to be thrown across the screen surface. The spring 302 provides elastic support and amplifies the vibration amplitude. Fine materials pass through the screen holes to achieve grading, while coarse materials on the screen are guided and discharged by the guide plate 305. Finally, the dust generated during screening is negatively pressured by the dust pump 401, and the dust is extracted by the dust suction head 403. The dust-laden gas enters the dust collection box 405 through the dust outlet head 406. The flow equalization plate 407 equalizes and diffuses the airflow, and the high-pressure atomizing nozzle 408 atomizes and sprays the liquid in the liquid tank 412, so that the dust particles and the atomized droplets can fully contact and agglomerate, and finally be discharged through the sewage pipe.
