Description

Technical Field

[0001] This utility model relates to the field of impurity removal equipment technology, specifically a negative pressure air chamber for separating light, floating foreign objects and dust from materials. Background Technology

[0002] A cleaning machine is a device that separates impurities from materials. For example, a cleaning machine that uses negative pressure to separate light, airy foreign objects and dust from materials achieves the separation function by utilizing the different weights of the materials and light, airy foreign objects. It is simple and convenient to use.

[0003] Existing negative pressure impurity separators have a negative pressure air chamber at the end. Utilizing the negative pressure generated by the air chamber, when the mixture of material and light foreign matter vibrates and moves inside the pipe, the light foreign matter can be drawn into the collection hopper by the negative pressure chamber, while the heavier material settles and is collected in the bottom collection hopper. This achieves the function of separating light foreign matter and dust from the material. However, existing negative pressure impurity separators can only perform negative pressure impurity removal on the mixture at the end. Because the material will squeeze and block the light foreign matter when it moves, the separation effect of light foreign matter is not good in a single negative pressure impurity removal.

[0004] To address these issues, we have developed a negative pressure air chamber for separating light, airborne foreign objects and dust from materials. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This invention proposes a negative pressure air chamber for separating light, airborne foreign objects and dust from materials. By coordinating the exhaust pipe 1 and exhaust pipe 2, it solves the problem of poor separation effect of light, airborne foreign objects during single negative pressure impurity removal.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a negative pressure air chamber for separating light, floating foreign matter and dust from materials, comprising a filter body, wherein a separation component is provided inside the filter body, and an exhaust pipe one and an exhaust pipe two are respectively provided inside the filter body.

[0009] The exhaust pipe 2 is internally connected to a diversion pipe. A fixed frame is fixedly installed on the outer surface of the diversion pipe. A fixed shaft is rotatably connected inside the fixed frame. A gear is fixedly installed on the outer surface of the fixed shaft. A toothed plate meshes with the gear teeth. A movable plate is fixedly installed on the outer surface of the toothed plate. A baffle is fixedly installed on the outer surface of the movable plate.

[0010] The inside of the diversion pipe is connected to a collection hopper, and a valve is installed at the opening of the collection hopper. A conveyor belt assembly is provided at the lower end of the valve.

[0018] Beneficial effects:

[0019] 1. The negative pressure air chamber for separating light foreign matter and dust from materials, through the cooperation of exhaust pipe one and exhaust pipe two, allows the material mixture to move from the separation component to the opening of exhaust pipe one during operation. At this time, the negative pressure formed inside exhaust pipe one can perform initial separation of light foreign matter and dust. Then, the material mixture moves again to the position of the diversion pipe, which has an L-shaped structure. Here, the light foreign matter and dust in the material can be separated again by exhaust pipe two located above. Then, the material can be collected by the collection hopper one below under the action of gravity. This allows for multiple separation and impurity removal of light foreign matter and dust in the material, resulting in better impurity removal effect. It realizes the function of multiple screening of light foreign matter by the impurity remover, which is conducive to increasing the separation effect of light foreign matter and dust.

The toothed plates can drive the moving plates and baffles to move. At this time, the moving plates and baffles can control the size of the pipe opening of the diversion pipe. It can be adjusted according to the separation needs, making it more convenient to use. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 - Figure 7As shown, this utility model provides a technical solution: a negative pressure air chamber for separating light, floating foreign objects and dust from materials, including a filter body 1, a separation component 2 inside the filter body 1, and a vibrating bed inside the filter body 1. The vibrating bed vibrates through components such as a buffer spring assembly and a vibrator, which can vibrate and move the material. The separation component 2 includes multiple air ducts inside. When the material passes through the vibrating bed, it is blown by the airflow at the bottom and can float and move at the bottom opening. At this time, large stones and other impurities in the material can fall into the opening due to their large weight, thus separating large impurities in the material.

[0032] The main body 1 of the dust collector is equipped with an exhaust pipe 3 and an exhaust pipe 4. The exhaust pipe 3 and the exhaust pipe 4 are respectively equipped with a connecting pipe 15 and a connecting pipe 16. The exhaust pipe 3 and the exhaust pipe 4 are interconnected. The exhaust pipe 3 is located at the front end of the exhaust pipe 4. It is connected to an external negative pressure device through the connecting pipe 15 and the connecting pipe 16 to form a negative pressure inside the exhaust pipe 3 and the exhaust pipe 4. The connected exhaust pipe 3 and the exhaust pipe 4 also facilitate the centralized collection and separation of light floating foreign objects and dust.

[0033] The main body 1 of the cleaning machine is equipped with a protective cover 17. The sorting component 2 is located inside the protective cover 17. The inlet of the exhaust pipe 3 is located inside the protective cover 17 and at the front end of the diversion pipe 5. The protective cover 17 can protect the exterior of the sorting component 2, reduce the dispersion of light foreign objects and dust, and improve the cleaning effect. The inlet of the exhaust pipe 3 is located at the front end of the inlet of the exhaust pipe 4, so light foreign objects and dust can be initially separated by the exhaust pipe 4.

[0034] A vertical plate 18 is fixedly installed at the lower end of the exhaust pipe 3. The vertical plate 18 is located at the front end of the diversion pipe 5. The vertical structure of the vertical plate 18 can block some light floating foreign objects and dust, improve the stability of light floating foreign objects and dust when moving vertically, and prevent the separated light floating foreign objects and dust from being drawn away by the negative pressure behind.

[0035] The interior of the exhaust pipe 4 is connected to a diversion pipe 5, and the interior of the diversion pipe 5 is connected to a collection hopper 12. A shut-off valve 13 is installed at the opening of the collection hopper 12. A conveyor belt assembly 14 is installed at the lower end of the shut-off valve 13. The diversion pipe 5 has an L-shaped structure, with the opening of the diversion pipe 5 located at the top. Therefore, when material enters the interior of the separation pipe, light and airy foreign objects and dust can be drawn and separated by the upper diversion pipe 5. At this time, heavier and heavier materials will enter the interior of the lower collection hopper 12 and enter the conveyor belt in the conveyor belt assembly 14 through the outlet outside the shut-off valve 13 for discharge and collection.

[0036] The interior of the exhaust pipe 24 is equipped with a collection hopper 20. The port of the collection hopper 20 is connected to the air shut-off device 21. Lightweight foreign objects and dust drawn by the exhaust pipe 13 and the exhaust pipe 24 will settle inside the collection hopper 20. The settled impurities will be discharged at the outlet of the air shut-off device 21 for treatment.

[0037] A fixed frame 6 is fixedly installed on the outer surface of the diverter pipe 5. A fixed shaft 7 is rotatably connected inside the fixed frame 6. A gear 8 is fixedly installed on the outer surface of the fixed shaft 7. A toothed plate 9 meshes with the teeth of the gear 8. A movable plate 10 is fixedly installed on the outer surface of the toothed plate 9. A baffle 11 is fixedly installed on the outer surface of the movable plate 10. A crank handle 19 is fixedly installed at one end of the fixed shaft 7. The gear 8 and the toothed plate 9 are symmetrically arranged at both ends of the fixed shaft 7. By rotating the gear 8, the movable plate 10 and the baffle 11 can be moved up and down. The size of the opening of the diverter pipe 5 can be adjusted by the movement of the movable plate 10 and the baffle 11. When the gear 8 rotates, the damping effect between the fixed frame 6 and the fixed shaft 7 can limit it to the outside of the fixed frame 6, which can fix the position of the movable plate 10 and the baffle 11. It can be adjusted according to the separation needs, making it more convenient to use.

[0038] Working principle: During operation, the material enters through the inlet on one side of the impurity removal machine body 1. Under the action of the separation component 2, large impurities in the material are separated. The separated material continues to move forward. When it moves to the position of the pipe opening of the exhaust pipe 3, it can perform initial negative pressure separation, which can extract light foreign objects and dust. Then the material continues to move into the interior of the diversion pipe 5. Inside the diversion pipe 5, the heavier material will fall into the collection hopper 12 for automatic collection. Light foreign objects and dust will be extracted and separated by the exhaust pipe 4 above. At this time, the negative pressure formed inside the exhaust pipe 3 and the exhaust pipe 4 can collect the light foreign objects and dust in the collection hopper 20 and discharge them after sedimentation.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
