Description

Technical Field

[0001] This utility model relates to the field of planar rotary cleaning screen technology, specifically a planar rotary cleaning screen with a dust collection device. Background Technology

[0002] The planar rotary cleaning screen is a specialized device for screening and cleaning granular materials. Its core feature is that it achieves automatic separation of materials and impurities through the screen structure. Due to the use of the planar rotary motion principle, it effectively reduces the dynamic-to-static ratio of the equipment and the dynamic load on the foundation.

[0003] The flat rotary cleaning screen easily generates a lot of dust during the feeding process. The existing flat rotary cleaning screen only performs dust suction inside the screen box and separates the dust from the material by wind power. However, the dust removal effect is not ideal due to the single dust suction structure.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a planar rotary cleaning screen with a dust collection device. Utility Model Content

[0005] The purpose of this invention is to provide a planar rotary cleaning screen with a dust collection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a planar rotary cleaning screen with a dust collection device, comprising a screen box, a feeding assembly, and a dust collection assembly. A top cover is installed on one side of the screen box, and a first screen and a second screen are sequentially installed inside the screen box from top to bottom. A feeding assembly is installed on the left side of the top cover, and the feeding assembly includes a feeding frame, a feeding hopper, and a guide plate. A feeding hopper is provided on one side of the feeding frame, and a guide plate is fixed to the lower inner side of the feeding frame, and the guide plate has an inclined structure. A first dust collection frame is installed on the upper inner wall of the feeding frame, and a first connecting pipe is connected to the upper side of the first dust collection frame. Dust collection assemblies are installed on the left side of the feeding frame and the right side of the screen box.

[0007] Furthermore, the first screen and the second screen are parallel to each other, and a first hopper is installed on the right side of the first screen.

[0008] Furthermore, a second hopper is installed on the right side of the second screen, and a third hopper is installed on the lower right side of the screen box.

[0009] Furthermore, the feeding assembly also includes a rotating shaft, a feeding plate, and a drive motor. The feeding plate is rotatably mounted on the inner left side of the feeding frame via the rotating shaft, and the drive motor is mounted on the outer end of the rotating shaft.

[0010] Furthermore, the dust collection assembly includes a collection box, a filter element, and a negative pressure suction pump. The filter element is installed in the middle of the inside of the collection box, and the negative pressure suction pump is installed on the upper side of the filter element.

[0011] Furthermore, a second dust collection frame is fixed to the lower side wall of the upper cover, and a connecting pipe is fixed to the upper side of the second dust collection frame, and a second connecting pipe is connected to the upper side of the connecting pipe.

[0012] Furthermore, both the first and second dust collection frames have mesh suction ports on their lower sides, and the first dust collection frame is connected to the collection box on the left side of the feed frame via a first connecting pipe.

[0013] Furthermore, the second dust collection frames are evenly distributed, and the second dust collection frames are interconnected with the collection box on the right side of the screen box through a connecting pipe and a second connecting pipe.

[0014] This utility model provides a planar rotary cleaning screen with a dust collection device, which has the following features:

[0015] Beneficial effects:

[0016] This utility model is equipped with a dust collection component. The first dust collection frame facilitates the suction of dust from the material being fed into the feeding frame, while several equally spaced second dust collection frames are used to suction the dust generated during the screening process inside the screening box. The negative pressure suction pump creates a negative pressure inside the collection box, which causes the first dust collection frame to send the absorbed dust into the collection box for centralized collection through the first connecting pipe. Similarly, the second dust collection frames collect dust through the connecting pipe and the second connecting pipe, while the filter element can intercept and prevent dust from entering the negative pressure suction pump.

[0017] This utility model is equipped with a feeding assembly. The first and second screens facilitate secondary screening of materials, and the feeding frame and hopper facilitate feeding. The inclined guide plate guides the material inside the feeding frame. At this time, the drive motor and rotating shaft facilitate the rotation of the material-pushing plate, which promotes the downward feeding of the guide plate. While the material-pushing plate is pushing the material, it also promotes the raising of dust to facilitate dust collection with the first dust collection frame. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 and Figure 3As shown, a planar rotary cleaning screen with a dust collection device includes a screen box 1, a feeding assembly 8, and a dust collection assembly 14. A top cover 2 is installed on one side of the screen box 1. Inside the screen box 1, a first screen 3 and a second screen 4 are installed sequentially from top to bottom, parallel to each other. A first hopper 5 is installed on the right side of the first screen 3, and a second hopper 6 is installed on the right side of the second screen 4. A third hopper 7 is installed on the lower right side of the screen box 1. The feeding assembly 8 is installed on the left side of the top cover 2. The feeding assembly 8 includes a feeding frame 801, a feeding hopper 802, and a guide plate 803. The feeding hopper 802 is located on the upper side of the feeding frame 801, and the guide plate 803 is fixed to the lower side of the inside of the feeding frame 801, with the guide plate 803 having an inclined structure. The feeding assembly 8 also includes a rotating shaft 804, a deflecting plate 805, and a drive motor 806. The left side of the inside of the feeding frame 801... A material-pushing plate 805 is rotatably mounted on the side via a rotating shaft 804, and a drive motor 806 is mounted on one end of the rotating shaft 804. The eccentric drive device facilitates the reciprocating linear motion of the screening box 1. The material is evenly distributed under the action of the screen movement, producing an automatic grading effect. The first screen 3 and the second screen 4 facilitate secondary screening of the material. The first hopper 5, the second hopper 6, and the third hopper 7 are respectively set to facilitate the discharge of unscreened material, primary screened material, and secondary screened material. The feeding frame 801 and the feeding hopper 802 facilitate feeding. The inclined guide plate 803 can guide the material inside the feeding frame 801. At this time, the drive motor 806 and the rotating shaft 804 facilitate the rotation of the material-pushing plate 805, so that the material-pushing plate 805 pushes the material to promote the downward feeding of the guide plate 803. At the same time, the material-pushing plate 805 also promotes the dust to be raised to cooperate with the first dust collection frame 9 for dust collection.

[0024] like Figure 1 and Figure 2As shown, a first dust collection frame 9 is installed on the upper inner wall of the feed frame 801, and a first connecting pipe 10 is connected to the upper side of the first dust collection frame 9. Dust collection assemblies 14 are installed on the left side of the feed frame 801 and the right side of the screening box 1. The dust collection assembly 14 includes a collection box 1401, a filter element 1402, and a negative pressure suction pump 1403. The filter element 1402 is installed in the middle of the collection box 1401, and the negative pressure suction pump 1403 is installed on the upper side of the filter element 1402. A second dust collection frame 11 is fixed to the lower side wall of the upper cover 2, and a connecting pipe 12 is fixed to the upper side of the second dust collection frame 11. A second connecting pipe 13 is connected to the upper side of the connecting pipe 12. Mesh suction ports are opened on the lower sides of the first dust collection frame 9 and the second dust collection frame 11. The first dust collection frame 9 is connected to the left side of the feed frame 801 through the first connecting pipe 10. The collection boxes 1401 are interconnected, and the second dust collection frames 11 are evenly distributed. The second dust collection frames 11 are interconnected with the collection box 1401 on the right side of the screening box 1 through the connecting pipe 12 and the second connecting pipe 13. The first dust collection frame 9 is convenient for dust collection in the material during feeding in the feeding frame 801, while several evenly distributed second dust collection frames 11 are used to collect dust generated during the screening process inside the screening box 1. The negative pressure suction pump 1403 creates a negative pressure inside the collection box 1401, which causes the first dust collection frame 9 to send the absorbed dust into the collection box 1401 for centralized collection through the first connecting pipe 10. Similarly, the second dust collection frames 11 collect dust through the connecting pipe 12 and the second connecting pipe 13, while the filter element 1402 can intercept and prevent dust from entering the negative pressure suction pump 1403.

[0025] In summary, as Figures 1-3 As shown, this planar rotary cleaning screen with a dust collection device can be used to first feed material through the feeding frame 801 and the feeding hopper 802. The guide plate 803 with an inclined structure on the lower side can guide the material inside the feeding frame 801. At this time, the drive motor 806 and the rotating shaft 804 can drive the rotation of the material-pushing plate 805, so that the material-pushing plate 805 pushes the material-pushing plate 803 downward. Then, the eccentric drive device can drive the reciprocating linear motion of the screen box 1. The material is evenly distributed under the action of the screen movement, producing an automatic grading effect. The first screen 3 and the second screen 4 can facilitate secondary screening of the material. The first discharge hopper 5, the second discharge hopper 6, and the third discharge hopper 7 can facilitate the discharge of unscreened material, primary screened material, and secondary screened material, respectively.

[0026] During this process, the material feeding plate 805 also promotes the raising of dust while feeding the material, so as to cooperate with the first dust suction frame 9 for dust suction. The first dust suction frame 9 can then suction the dust in the material fed into the feeding frame 801. Several second dust suction frames 11 distributed at equal distances are used to suction the dust raised during the screening process inside the screening box 1. The setting of the negative pressure suction pump 1403 creates a negative pressure inside the collection box 1401, which causes the first dust suction frame 9 to send the absorbed dust into the collection box 1401 for centralized collection through the first connecting pipe 10. Similarly, the second dust suction frames 11 collect dust through the connecting pipe 12 and the second connecting pipe 13. The filter element 1402 can play an interception role to prevent dust from entering the negative pressure suction pump 1403. In this way, the use process of the planar rotary cleaning screen with dust collection device is completed.
