Abstract
Description
Technical Field
[0001] This utility model relates to a novel dual-channel vibrating cleaning screen, belonging to the field of cleaning screen technology. Background Technology
[0002] A vibrating cleaning screen is a device that uses vibration to screen and clean materials, and it is widely used in various industries such as grain, mining, chemical, and construction. Most existing vibrating cleaning screens are single-channel structures, resulting in low material screening efficiency, poor cleaning and grading effects, and consequently, low output.
[0003] A Chinese utility model patent, CN203599051U, describes a three-layer self-balancing vibrating cleaning screen. This patent includes a frame, a screen body, a feed box, and a discharge box. Elastic elements are installed at the bottom of the front and rear sides of the screen body and supported on the frame. A vibration motor is mounted on the side of the screen body. The screen body consists of an outer shell and three screen plates—a first screen plate, a second screen plate, and a third screen plate—installed diagonally from top to bottom within the outer shell. Limiting blocks are provided within the screen body to restrict the downward movement of each screen plate. The aperture size of the three screen plates decreases sequentially from top to bottom. The discharge box is equipped with a large impurity outlet, a small impurity outlet, and a clean material outlet. The end of the first screen plate is connected to the large impurity outlet, and the second and third screen plates are connected to the clean material outlet and the small impurity outlet, respectively. A movable baffle plate is installed in the discharge box. The movable baffle plate is fixedly connected to the rotating shaft and hinged to the side wall of the discharge box through the rotating shaft. The rotating shaft is connected to an adjustment and positioning mechanism. This patent realizes the function of cleaning materials of different particle sizes with the same equipment. However, this patent classifies materials layer by layer through multiple screen plates, resulting in low screening efficiency. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a novel dual-channel vibrating cleaning screen that can realize simultaneous feeding and screening of materials through two channels, thereby improving screening efficiency and cleaning and grading effect.
[0005] The novel dual-channel vibrating cleaning screen of this utility model includes a screen body, inside which an upper screen plate and a lower screen plate are installed. An upper movable bottom plate is installed below the upper screen plate, and a lower bottom plate is installed below the lower screen plate. The upper screen plate, the lower screen plate, and the upper movable bottom plate all adopt a drawer-type structure. Slide angle irons are set on the inner wall of the screen body corresponding to the upper movable bottom plate and the lower screen plate. The lower screen plate and the upper movable bottom plate slide along the upper surface of the slide angle irons to facilitate quick disassembly and replacement.
[0006] The upper screen plate has a discharge hole at the front end to allow material to fall into the lower part. Both the upper and lower screen plates are connected to the granular material outlet, and both the upper movable bottom plate and the lower bottom plate are connected to the powder material outlet.
[0007] The technical solution of this utility model is to provide a novel dual-channel vibrating cleaning screen. After the material enters the screen body, a part of the material moves downwards at an incline through the upper screen plate. During this process, smaller powders pass through the upper screen plate and fall to the upper movable bottom plate, and then move along the upper movable bottom plate and are discharged from the powder outlet. Larger granules move downwards along the upper screen plate and are finally discharged from the granule outlet.
[0008] Another portion of the material passes through the discharge holes on the upper screen plate and falls onto the lower screen plate. It then moves downwards at an angle through the lower screen plate. During this process, smaller powder particles pass through the lower screen plate and fall onto the lower bottom plate, then move along the lower bottom plate and are discharged from the powder outlet. Larger granular materials move downwards along the lower screen plate and are eventually discharged from the granular material outlet.
[0009] Preferably, a frame is provided below the screen body, and the screen body is elastically connected to the frame through a rubber support spring. Vibration motors are installed on the outer walls of both sides of the screen body, and the vibration motors cause the screen body to vibrate with the cooperation of the rubber support springs.
[0010] Preferably, a feed box is installed above the screen body, and a feed inlet is provided on the top of the feed box.
[0011] Preferably, a front baffle is hinged to one end of the screen body near the feed box, and screen plate pressing mechanisms are provided on both sides of the inner wall of the screen body for pressing the upper screen plate, the upper movable bottom plate and the lower screen plate.
[0012] Preferably, the end of the screen body away from the feed box is connected to the discharge box, and the granular material outlet and the powder material outlet are both located at the bottom of the discharge box.
[0013] Preferably, a screen is installed on the top surface of the upper and lower screen plates, and a support net is installed on the bottom surface of the upper and lower screen plates. A high-elasticity rubber ball is provided between the support net and the screen. When the equipment is running, the vibrating motor drives the screen body to vibrate back and forth, thereby causing the high-elasticity rubber ball to bounce and continuously knock on the screen to clean the screen and prevent blockage.
[0014] The advantages of this utility model compared with the prior art are:
[0015] The novel dual-channel vibrating cleaning screen of this utility model forms a dual-channel structure by setting an upper screen plate and a lower screen plate, which simultaneously screens materials, thereby improving screening efficiency. By setting high-elastic rubber balls in the upper and lower screen plates to continuously tap the screen, the screen is prevented from clogging, thereby improving the cleaning and grading effect and increasing output.

[0020] The present invention will be further described below with reference to specific embodiments.
[0021] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.
[0022] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.
[0023] like Figures 1-3 As shown, this embodiment is achieved through the following technical solution: It includes a sieve body 16, inside which an upper sieve plate 3 and a lower sieve plate 5 are installed. An upper movable bottom plate 4 is installed below the upper sieve plate 3, and a lower bottom plate 7 is installed below the lower sieve plate 5. The upper sieve plate 3, the lower sieve plate 5, and the upper movable bottom plate 4 all adopt a drawer-type structure. Slide angle irons 15 are provided on the inner wall of the sieve body 16 corresponding to the upper movable bottom plate 4 and the lower sieve plate 5. The lower sieve plate 5 and the upper movable bottom plate 4 slide along the upper surface of the slide angle irons 15 to facilitate quick disassembly and replacement. The upper sieve plate 3 has a discharge hole 17 at its head end to allow material to fall into the lower part. The upper sieve plate 3 and the lower sieve plate 5 are both connected to the granular material outlet 11, and the upper movable bottom plate 4 and the lower bottom plate 7 are both connected to the powder material outlet 10.
[0024] In this embodiment, a frame 9 is provided below the screen body 16. The screen body 16 is elastically connected to the frame 9 through a rubber support spring 8. Vibration motors 14 are installed on the outer walls of both sides of the screen body 16. The vibration motors 14 cause the screen body 16 to vibrate with the cooperation of the rubber support springs 8.
[0025] A feed box 2 is installed above the screen body 16, and a feed inlet 1 is provided on the top of the feed box 2. A front baffle 6 is hinged to one end of the screen body 16 near the feed box 2. Screen plate pressing mechanisms 13 are provided on both sides of the inner wall of the screen body 16 for pressing the upper screen plate 3, the upper movable bottom plate 4, and the lower screen plate 5.

Screen meshes are installed on the top surfaces of the upper screen plate 3 and the lower screen plate 5, and support nets are installed on the bottom surfaces of the upper screen plate 3 and the lower screen plate 5. High-elasticity rubber balls 18 are placed between the support nets and the screen meshes. When the equipment is running, the vibration motor 14 drives the screen body 16 to vibrate back and forth, thereby causing the high-elasticity rubber balls 18 to bounce and continuously knock on the screen meshes to clean them and prevent clogging.
[0027] The working process of this utility model is as follows:
[0028] Material enters the screen body 16 through the feed inlet 1. Part of the material moves downwards at an incline through the upper screen plate 3. During this process, smaller powder particles pass through the upper screen plate 3 and fall onto the upper movable bottom plate 4, then move along the upper movable bottom plate 4 and are discharged from the powder outlet 10. Larger granules move downwards along the upper screen plate 3 and are finally discharged from the granule outlet 11. Another part of the material passes through the discharge hole 17 on the upper screen plate 3 and falls onto the lower screen plate 5. It moves downwards at an incline through the lower screen plate 5. During this process, smaller powder particles pass through the lower screen plate 5 and fall onto the lower bottom plate 7, then move along the lower bottom plate 7 and are discharged from the powder outlet 10. Larger granules move downwards along the lower screen plate 5 and are finally discharged from the granule outlet 11.
