Description

Technical Field

[0001] This utility model relates to the technical field of impurity removal devices, specifically an impurity removal device that combines positive pressure wind separation and negative pressure wind separation. Background Technology

[0002] Impurity collection devices are mainly used to collect impurities generated during the production process to ensure the purity and quality of products. They are commonly used in the grain processing, mining, or chemical industries.

[0003] Existing wind-powered impurity removal devices typically use air to directly blow away lighter impurities from the transported material. However, after this method, users still need to remove heavier impurities, requiring them to move the material to a separate machine for this purpose, which is cumbersome. To address this issue, we offer a combined positive and negative pressure wind separation device. Utility Model Content

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a purification device combining positive pressure air separation and negative pressure air separation, comprising a support frame, a separation chamber installed on the upper surface of the support frame, a spring connected to the upper surface of the support frame, and a screen shell connected to the upper end of the spring;

[0008] The screen housing is equipped with a support plate, the support plate has an air outlet, the screen housing is connected to an air inlet pipe, and the screen housing is connected to a discharge pipe.

[0009] The separation chamber is equipped with an exhaust pipe, a discharge port, and a second discharge port.

[0011] Furthermore, a fixing plate is connected to the outer surface of the separation chamber, and a rotating rod is connected inside the fixing plate.

[0012] Furthermore, a gear is connected to the outer surface of the rotating rod, a toothed plate meshes with the outer surface of the gear, and a baffle is connected to the outer surface of the toothed plate.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, this impurity removal device combining positive and negative pressure air separation has the following advantages:

[0019] I. This impurity removal device, which combines positive and negative pressure air separation, works in conjunction with components such as the inlet pipe and the outlet. First, the inlet pipe allows air to blow out from the outlet, causing the material passing through to be suspended in a suspended state. Heavier impurities mixed in will fall out of the outlet because they cannot be blown by the air, thus cleaning up the heavier impurities. The exhaust pipe can create a negative pressure in the separation chamber, allowing lighter impurities in the material entering the separation chamber to be sucked away, while the material falls directly out from the outlet. This allows a single machine to clean both lighter and heavier impurities, solving the problem of cumbersome material handling.

[0020] Second, this impurity removal device, which combines positive and negative pressure air separation, works in conjunction with components such as the collection box and baffle. The collection box can collect heavier impurities that fall from the air outlet, preventing them from falling everywhere and making it easier for staff to clean. The baffle can block the entrance to the separation chamber, preventing external dust from entering the device when it is not in use. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] The blower 12 in this utility model is a common electrical device in the prior art. This application will not elaborate on its model or internal structure.

[0034] like Figures 1-9 As shown, this utility model provides a technical solution: a purification device combining positive pressure wind separation and negative pressure wind separation, including a support frame 1, a separation chamber 2 installed on the upper surface of the support frame 1, a spring 3 connected to the upper surface of the support frame 1, and a screen shell 4 connected to the upper end of the spring 3. The support frame 1 provides support for the separation chamber 2, the support frame 1 restricts the position of the spring 3, the spring 3 can provide certain support for the screen shell 4, and a vibration device is installed on the screen shell 4, which causes the screen shell 4 to vibrate.

[0035] The screen shell 4 has a support plate 5 installed inside, and the support plate 5 has an air outlet 6 inside. The screen shell 4 is connected to an air inlet pipe 7 and an air outlet pipe 8. When the screen shell 4 vibrates, it will cause the support plate 5 to vibrate. When the material is poured onto the support plate 5, the material will move towards the separation chamber 2 with the vibration of the support plate 5. The support plate 5 has an inclined air outlet 6 inside, and the air inlet pipe 7 allows air to be blown out from the air outlet 6. The air blown out from the air outlet 6 allows the material passing through here to pass through in a suspended manner, while the heavier impurities in the material will fall from the air outlet 6 due to gravity. These falling impurities will enter the air outlet pipe 8 along the slope inside the screen shell 4.

[0036] The separation chamber 2 is equipped with an exhaust pipe 9, a discharge port 10, and a discharge port 21. The separation chamber 2 restricts the position of the exhaust pipe 9, which creates a negative pressure in the separation chamber 2, allowing the material entering the separation chamber 2 to be subjected to a certain suction force. This suction force removes lighter impurities from the material, which then fall out from the discharge port 10 under the influence of gravity. The removed impurities fall out from the discharge port 21. The other end of the exhaust pipe 9 is connected to a device that can draw in air.

[0037] A blower 12 is installed inside the support frame 1, an air distribution box 13 is installed inside the support frame 1, and a collection box 14 is installed inside the support frame 1. The support frame 1 restricts the position of the blower 12. The output end of the blower 12 is connected to the air distribution box 13 through a pipe. The air distribution box 13 is connected through an air inlet pipe 7. The blower 12 blows the gas. The blower 12 rotates eccentrically through an offset rotor inside the cylinder. The volume change between the blades in the rotor slots draws in air, compresses it, and discharges it.

[0038] A fixing plate 15 is connected to the outer surface of the separation chamber 2, and a rotating rod 16 is connected inside the fixing plate 15. The separation chamber 2 restricts the position of the fixing plate 15, and the fixing plate 15 provides support for the rotating rod 16.

[0039] A gear 17 is connected to the outer surface of the rotating rod 16. A toothed plate 18 meshes with the outer surface of the gear 17. A baffle 19 is connected to the outer surface of the toothed plate 18. A handle is connected to one end of the rotating rod 16. The user can rotate the rotating rod 16 with a wrench. The rotation of the rotating rod 16 will cause the gear 17 to rotate. The rotation of the gear 17 will cause the toothed plate 18 to move, thereby controlling the toothed plate 18 to rise or fall. The movement of the toothed plate 18 will also cause the baffle 19 to move, thereby controlling whether the baffle 19 blocks the entrance of the separation chamber 2.

[0040] The outer surface of the baffle 19 is slidably connected to the outer surface of the separation chamber 2. The outer surface of the rotating rod 16 is connected to the limit block 20. The outer surface of the limit block 20 is in contact with the outer surface of the gear 17, and the position of the gear 17 is blocked by the limit block 20.

[0041] The upper surface of the support frame 1 is connected to a limiting plate 21. A conveyor belt 22 is installed inside the limiting plate 21. A collection tray 23 is connected to the outer surface of the limiting plate 21. Materials falling from the discharge port 10 can fall directly onto the conveyor belt 22 inside the collection tray 23, and the conveyor belt 22 can send these materials out.

[0042] The upper surface of the support frame 1 is connected to a protective shell 24, and the outer surface of the separation chamber 2 is connected to a limiting shell 25. The outer surface of the protective shell 24 is connected to the outer surface of the limiting shell 25. The protective shell 24 can block the lighter impurities blown up by the air outlet 6, so that these lighter impurities will not fly too high.

[0043] The limiting shell 25 has an exhaust pipe 26 inside and an air inlet 27 inside. The other end of the exhaust pipe 26 is connected to a device similar to a vacuum cleaner. The vacuum cleaner device causes the exhaust pipe 26 to generate suction. The suction generated by the exhaust pipe 26 will draw air from the air inlet 27 and suck away the lighter impurities blown up by the air outlet 6.

[0044] Working principle: When in use, the blower 12 needs to be started first. The blower 12 will blow air into the air distribution box 13, which will send the blown air into the air inlet pipe 7, so that the air will be sprayed out from the air outlet 6. Then, the material is poured onto the support plate 5 and the support plate 5 vibrates. When the support plate 5 vibrates, it will move the material towards the separation chamber 2. When the material passes through the air outlet 6, the gas coming out of the air outlet 6 will make the material float over, while the heavier impurities will fall out of the air outlet 6, and the lighter impurities will be blown to a high place and sucked away by the second exhaust pipe 26. Then the material will be sent into the separation chamber 2. The separation chamber 2 is in a negative pressure state under the action of the first exhaust pipe 9. The lighter impurities will be sucked away and fall out from the second discharge port 11. The material will fall from the first discharge port 10 onto the conveyor belt 22.
