Description

Technical Field

[0001] This utility model relates to the field of particle sorting technology, specifically to an activated carbon particle sorting filter. Background Technology

[0002] Granular activated carbon is divided into shaped and irregular granules. It is mainly made from coconut shells, fruit shells and coal as raw materials, and is refined through a series of production processes. The product is widely used in drinking water, industrial water, brewing, waste gas treatment, decolorization, desiccant, gas purification and other fields. Granular activated carbon uses high-quality anthracite as raw material and is refined through advanced technology. It has a black irregular granule appearance. It has a well-developed pore structure, good adsorption performance, high mechanical strength, easy regeneration, and low cost.

[0003] When processing activated carbon, impurities and broken particles can be filtered out through sorting and filtration, ensuring that the activated carbon maintains a high quality. However, traditional vibrating screen sorting is prone to dust pollution, the adsorption characteristics of activated carbon cause the screen to clog easily, and it cannot achieve multi-stage simultaneous particle size sorting and online filtration.

[0004] To address the problems existing in the above-mentioned technologies, an activated carbon particle sorting filter is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides an activated carbon particle sorting filter, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon particle sorting filter, comprising a spiral sorting tower, a multi-stage filtration assembly, and a pneumatic circulation system;

[0007] A storage hopper is fixedly installed on the top of the spiral sorting tower. A conical cylinder is fixedly installed inside the spiral sorting tower. A guide cone is provided inside the conical cylinder. A spiral guide plate is fixedly installed on the outer wall of the guide cone. A first filter chamber, a second filter chamber, and a third filter chamber are formed between the conical cylinder and the spiral sorting tower from top to bottom. A base frame is fixedly installed at the bottom of the spiral sorting tower.

[0008] The pneumatic circulation system includes a cyclone separator cone, a spiral inlet pipe, a clean air outlet, and an ash hopper.

[0009] Activated carbon granules are stored inside the storage hopper. When the motor is started, the drive shaft rotates the feeding plate at a constant speed. The activated carbon granules inside the storage hopper enter the spiral sorting tower through the feeding plate. Under the action of gravity, the activated carbon granules move along the spiral guide plate. The fine particles in the activated carbon granules are carried into the cyclone separator cone by the rising airflow formed in the conical cylinder after the fan is turned on. The coarse particles overcome the airflow resistance and fall into the third filter chamber. The medium-sized particles are pre-sorted when passing through the first and second screens. The combination of gravity sedimentation, pneumatic separation and mechanical screening mechanisms greatly improves the sorting efficiency.

[0010] As a preferred embodiment of this utility model, a motor is installed on the top of the storage hopper, a drive shaft is fixedly connected to the output end of the motor, a feeding port is formed at the connection between the motor and the spiral sorting tower, and a feeding plate is fixedly installed on the drive shaft at the feeding port.

[0011] The storage hopper pre-stores activated carbon granules, and the motor-driven feeding plate ensures that the activated carbon granules are fed evenly, while also preventing the activated carbon granules from clogging the feed port.

[0012] As a preferred technical solution of this utility model, the conical cylinder is fixedly connected to the drive shaft, a conical material guiding area is formed at the top of the conical cylinder, a flexible sealing strip is provided at the edge of the spiral guide plate near the conical cylinder, and a resistance reduction hole is opened on the surface of the spiral guide plate.

[0013] Activated carbon particles that enter the spiral sorting tower can move downwards along the spiral guide plate. The flexible sealing strip can fill the gaps to prevent activated carbon particles from entering and causing uneven sorting. The spiral guide plate has resistance-reducing holes on its surface to ensure the flow guidance function and reduce the resistance to airflow.

[0014] As a preferred technical solution of this utility model, the multi-stage filtration assembly includes a first screen disposed between the first filtration chamber and the conical cylinder, a second screen disposed between the second filtration chamber and the conical cylinder, and a discharge port disposed between the third filtration chamber and the conical cylinder.

[0015] The first screen, the second screen, and the feed inlet have corresponding apertures of 100 mesh / 50 mesh / 20 mesh, and the activated carbon particles can be sorted by passing through the first screen, the second screen, and the feed inlet.

[0016] As a preferred embodiment of the present invention, the first filter chamber has a first material outlet on its side wall, the second filter chamber has a second material outlet on its side wall, and the third filter chamber has a third material outlet on its side wall.

[0017] The activated carbon particles sorted from the first, second, and third filter chambers can be removed through the first, second, and third feed ports.

[0018] As a preferred embodiment of this utility model, the pneumatic circulation system includes a fan installed at the bottom of the conical cylinder and a cyclone separator cone disposed on one side of the spiral sorting tower, with a protective cover installed above the fan.

[0019] The blower generates negative pressure to draw the airflow from the bottom of the spiral separator tower into the conical cylinder. The airflow entering the conical cylinder can spiral upward along the spiral guide plate, thus using pneumatic force to separate activated carbon particles. The protective cover can protect the top of the blower to prevent activated carbon particles from entering the blower. The cyclone separator cone can work with the rising airflow inside the spiral separator tower to separate and filter the tiny particles carried in the gas from the air.

[0020] As a preferred technical solution of this utility model, a spiral inlet pipe is provided on the cyclone separator cone, the end of the spiral inlet pipe away from the cyclone separator cone extends to the top of the spiral sorting tower, a clean air outlet is provided at the top of the cyclone separator cone, a ash hopper is provided at the bottom of the cyclone separator cone, and a docking frame is fixedly connected between the cyclone separator cone and the spiral sorting tower.

[0021] The rising airflow carrying fine particles inside the spiral separator tower can be tangentially introduced into the cyclone separator cone through the spiral inlet pipe. The centrifugal force generated when the gas-solid mixture rotates at high speed separates the particles from the airflow. The particles are discharged downward through the ash hopper into the cyclone separator cone, and the separated clean air is discharged from the cyclone separator cone through the clean air outlet.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The activated carbon particles inside the storage hopper can enter the spiral sorting tower through the feeding plate. Under the action of gravity, the activated carbon particles move along the spiral guide plate. The fine particles in the activated carbon particles can be carried into the cyclone separator cone by the rising airflow formed in the cone-shaped cylinder after the blower is turned on. The coarse particles overcome the airflow resistance and fall into the third filter chamber. The medium particles can be pre-sorted when passing through the first and second screens. The combination of gravity settling, pneumatic separation and mechanical screening triple mechanism greatly improves the sorting efficiency. Attached Figure Description

[0037] Working principle: First, activated carbon granules are stored inside the storage hopper 2. The motor 11 drives the transmission shaft 12, causing the feeding plate 13 to rotate at a constant speed. The activated carbon granules inside the storage hopper 2 can enter the spiral separator 1 through the feeding plate 13. Under the action of gravity, the activated carbon granules move along the spiral guide plate 8. The blower 9 generates negative pressure, drawing the airflow from the bottom of the spiral separator 1 into the conical cylinder 3. The airflow entering the conical cylinder 3 spirals upwards along the spiral guide plate 8, achieving the separation of activated carbon granules using pneumatic force. Fine particles in the activated carbon granules are carried into the cyclone separator cone 14 by the rising airflow formed inside the conical cylinder 3 after the blower 9 is turned on. The rising airflow carrying fine particles inside the spiral separator 1 is tangentially introduced into the cyclone separator cone 14 through the spiral inlet pipe 15. Inside the cyclone separator cone 14, the centrifugal force generated by the high-speed rotation of the gas-solid mixture separates the particles from the airflow. The particles are discharged downward through the ash hopper 17 and discharged from the cyclone separator cone 14. The separated clean air is discharged from the cyclone separator cone 14 through the clean air outlet 16. Coarse particles overcome airflow resistance and fall into the interior of the third filter chamber 6, while medium-sized particles can be pre-sorted by passing through the first screen 401 and the second screen 501. The apertures of the first screen 401, the second screen 501, and the discharge port 601 are 100 mesh / 50 mesh / 20 mesh. The activated carbon particles can be sorted by passing through the first screen 401, the second screen 501, and the discharge port 601. The combination of gravity sedimentation, pneumatic separation, and mechanical screening mechanisms greatly improves the sorting efficiency.
