Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screen equipment, in particular to a residual material bin of a vibrating screen that prevents material blocking. Background Art

[0002] Vibrating screen is a commonly used separation equipment, which can be used with various sieve plates to separate and grade various materials. Generally speaking, the mesh size of the bottom sieve plate of the vibrating screen is the densest, which can screen out particles with smaller particle sizes and eventually fall into the residual material bin.

[0003] In the aluminum alloy smelting process, the raw materials need to be made into pellets by physical means, and the pellets are used to support each other in the furnace for ventilation, so as to accelerate the smelting temperature and material melting reaction during the smelting process. The pellets used are generally made by a drum or a pellet press. The produced pellets have defects or small particle sizes that need to be screened out, and some unformed powder also needs to be sent back to the previous process to be re-formed into pellets. Therefore, the residual material bin at the bottom of the vibrating screen used needs to recover the powder, but because the powder particles are small, they are easy to accumulate and adhere to the residual material bin. Long-term work or a large amount of powder will lead to poor discharge of the residual material bin and blockage. Utility Model Content

[0004] The utility model aims to provide a residual material bin of a vibrating screen which can prevent material blocking, so as to solve the problems existing in the prior art.

[0005] The utility model is implemented by the following technical scheme: a residual material bin of a vibrating screen to prevent blocking of materials, comprising a residual material bin body, a partition, a float valve, a cyclone separator, a discharge chute and an air inlet pipe, a discharge port is provided on one side of the residual material bin body, the discharge port is connected with the discharge chute, a partition is obliquely installed in the residual material bin body, the height of the partition placed at one end of the discharge port is lower than the oblique setting on the opposite side, a plurality of openings are provided on the partition, a float valve is movably installed in each opening, an air inlet pipe is provided on the residual material bin body and below the partition, and the inlet of the cyclone separator is connected with the discharge chute.

[0006] Furthermore, the float valve includes a cover plate and a slide. The cover plate is in active contact with the top surface of the partition. Two slides are symmetrically arranged at the bottom of the cover plate. The two slides are placed in the opening of the partition. The slide is fan-shaped. The bottom end edge of the slide is bent outward to form a bent portion, and the bent portion is in active contact with the bottom surface of the partition.

[0007] Furthermore, a row of a plurality of high-pressure nozzles are installed on the inner wall of the residual material bin above the partition, and the high-pressure nozzles are installed on the inner wall of the residual material bin at the end edge of the higher side of the partition.

[0008] Furthermore, the high-pressure nozzle is a duckbill-shaped nozzle, and the air outlet direction of the high-pressure nozzle is parallel to the direction of the partition.

[0009] The advantages of the utility model are as follows: by installing a partition and a float valve inside the residual material bin body, high-pressure air is introduced into the cavity between the partition and the residual material bin body, so that the powdered material on the partition can be intermittently cleaned, and the cyclone separator provided at the discharge chute can collect the dust in the airflow together without causing dust spillage. The overall structure is simple, and the effect of cleaning the powdered material accumulated in the residual material bin is good, which can effectively avoid the blockage of the residual material bin.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "front", "back", "top", "bottom", "left", "right", "vertical", "horizontal", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0016] like Figure 1 , Figure 2As shown: a residual material bin of a vibrating screen for preventing material blocking, comprising a residual material bin body 1, a partition 2, a float valve 3, a cyclone separator 4, a discharge chute 5 and an air inlet pipe 6. A discharge port 101 is provided on one side of the residual material bin body 1, and the discharge port 101 is communicated with the discharge chute 5. A partition 2 is obliquely installed in the residual material bin body 1, and the height of one end of the partition 2 placed at the discharge port 101 is lower than the oblique setting on the opposite side. The material under the screen plate of the vibrating screen falls onto the partition 2. Since the partition 2 is inclined, the material moves toward the discharge port 101 under the action of gravity and finally discharges from the discharge chute 5. A plurality of openings 201 are provided on the partition 2.

[0017] like Figure 3 As shown: a float valve 3 is movably installed in each opening 201, and the float valve 3 includes a cover plate 301 and a slide 302. The cover plate 301 is in active contact with the top surface of the partition plate 2. Two slides 302 are symmetrically arranged at the bottom of the cover plate 301. The two slides 302 are placed in the opening 201 of the partition plate 2. The slides 302 are fan-shaped, and the bottom end edge of the slide 302 is bent outward to form a bent portion 303. The bent portion 303 is in active contact with the bottom surface of the partition plate 2. The longer arc edge of the slide 302 faces the discharge port 101, so that when the float valve 3 is opened upward, the larger opening side faces the discharge port 101, which is convenient for blowing the material to the discharge port 101. The cover plate 301 is in the open state. When in the state, it is at a certain angle with the partition 2, which plays a role in guiding the airflow to the discharge port 101. The float valve 3 can move up and down. When working normally, the float valve 3 blocks the opening 201 to prevent the material from falling under the partition 2; an air inlet pipe 6 is provided on the residual material bin body 1 and below the partition 2. The partition 2 divides the residual material bin body 1 into two upper and lower cavities. The lower cavity of the partition 2 is connected with the air inlet pipe 6, and the air inlet pipe 6 is connected to an air compressor. The inlet of the cyclone separator 4 is connected with the discharge chute 5. A canvas hose bellows can be used to connect the inner cavity of the discharge chute 5 with the inlet of the cyclone separator 4 to ensure that the vibration will not be transmitted to the relevant pipelines of the cyclone separator 4 when the vibrating screen is working. When too much powdery material accumulates in the residual material bin, the air compressor can be turned on to supply air to the lower cavity of the partition 2 through the air inlet pipe 6. The air lifts the float valve 3 on the partition 2, and the air is ejected from the opening 201 to blow the powdery material away from the partition 2. At the same time, the cyclone separator 4 is turned on to introduce the air carrying the powdery material into the cyclone separator 4 for solid-gas separation, and then the collected powdery material is returned to the previous pelletizing process, which can reduce material waste.

[0018] In order to ensure the cleaning effect of the powdered material deposited on the partition 2, a row of several high-pressure nozzles 7 are installed above the partition 2 and on the inner wall of the residual material bin body 1. The high-pressure nozzle 7 is installed on the inner wall of the residual material bin body 1 at the end of the higher side of the partition 2. The high-pressure nozzle 7 is a duckbill nozzle. The air outlet direction of the high-pressure nozzle 7 is parallel to the direction of the partition 2, so that the airflow sprayed by the high-pressure nozzle 7 can be directed toward the discharge port 101, and the powdered material is driven to be discharged by the airflow. The air intake of the high-pressure nozzle 7 must be lower than the air intake of the air intake pipe 6 to avoid affecting the normal opening of the float valve 3.
