Description

Technical Field

[0001] This utility model relates to the field of waste material air separation, and in particular to a primary crushing material air separation device with stable and unblocked feeding. Background Technology

[0002] In the treatment of bulky solid waste, crushers are often used to coarsely crush the waste into primary crushed material. Primary crushed material is a mixture of small pieces of material, lightweight materials, dust, etc. Primary crushed material usually needs to be sorted by air classifier. The current problems with bulk material air classifiers are: First, the feeding device and the sorting body are an integrated structure. Primary crushed material has a large gravitational potential energy and kinetic potential energy. The feeding device is subjected to the inertial impact force of material conveying under rigid load, which makes the feeding device easy to be damaged and requires frequent maintenance and replacement, resulting in high equipment operating costs. Second, material is prone to clogging in the feeding device, requiring manual unclogging, which is dangerous, has poor operational safety, and requires a lot of time, affecting the efficiency of equipment use. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a primary crushing material air separation device with stable and unblocked feeding.

[0004] According to one aspect of the present invention, a stable and unblockable feeding primary crushing air classifier includes: an air classifier body, a feed nozzle, and a blockage remover;

[0005] The air classifier body is equipped with an air classifier cavity that runs vertically through the air classifier cavity. The upper end of the air classifier cavity is the outlet for light materials and the lower end is the outlet for large materials. The upper side of one side of the air classifier cavity is equipped with a horizontal mixing inlet and the lower side of the other side is equipped with a horizontal air inlet.

[0006] The feed nozzle includes left and right open guide pipes. The inner end of the guide pipe is inserted into the mixing inlet and an elastic seal is installed at the connection gap between the two. The lower end of the guide pipe is connected to the air separation chamber. The outer end of the guide pipe is tilted upward to form an inclined guide channel. A blockage relief hole is opened in the middle of the upper side of the guide pipe to connect to the guide channel. A scraper is fixedly connected to the lower end of the inner side of the blockage relief hole.

[0007] The unblocking device includes an unblocking roller and an unblocking motor. The roller body of the unblocking roller is rotatably set in the unblocking hole and one end of its shaft is connected to the unblocking motor.

[0008] The initial crushed material enters the guide channel at an angle from the upper port on the outside of the guide pipe. The unblocking motor drives the unblocking roller to rotate, thereby pushing the material to move. The scraper cleans away the entangled and adhered material on the unblocking roller and enters the air classifier channel for sorting through the lower port and the mixing inlet. Under the action of the airflow from bottom to top, the light material is discharged from the light material outlet, and the heavier large material is discharged from the large material outlet.

[0009] In some implementations, the mixing inlet is a rectangular opening, and the gap between the vertical rectangular section at the lower end of the feed pipe and the rectangular opening is set.

[0010] In some implementations, the lower end of the feed tube is covered with an elastic seal, which is press-fitted into the mixing inlet.

[0011] In some implementations, the resilient seal is a rectangular rubber ring.

[0012] In some implementations, the feed tube is a rectangular tube or a rectangular tapered tube. When it is a rectangular tapered tube, the cross-section of its lower port is smaller than that of its upper port.

[0013] In some embodiments, a three-dimensional frame structure feeding support is also included, which is independently located on one side of the air classifier body, and the feeding nozzle is fixedly connected to the feeding support.

[0014] In some implementations, a seated bearing is fitted onto each end of the unblocking roller shaft, and the seated bearing is fixedly connected to the feed support via an adapter.

[0015] In some implementations, the adapter is a rigid metal seat, and a rubber buffer block is provided between the adapter and the bearing with a seat to achieve small-clearance floating.

[0016] In some implementations, the unblocking motor is a stepper motor with a hollow shaft structure.

[0017] In some embodiments, the inner surface of the scraper is an arc surface that cooperates with the unblocking roller, and the small gap of the arc surface is located outside the unblocking roller.

[0018] The advantages of this stable, clog-free feeding primary crushing air classifier are as follows: First, the air classifier body and the feed nozzle adopt a separate structure, and the connection between the two is equipped with an elastic seal, which can effectively buffer the inertial impact force of the primary crushed material, protect the feeding device, reduce the frequency of maintenance and replacement, and effectively reduce costs. Second, the feed nozzle is equipped with a blockage remover, which can effectively prevent and remove blockages, ensuring stable and clog-free feeding, avoiding manual blockage removal, improving operational safety, allowing the equipment to work continuously for a long time, and increasing production efficiency. Third, the blockage remover is equipped with a scraper to prevent the blockage remover roller from carrying out material, ensuring clean production. Fourth, the blockage remover is located in the guide pipe, which does not increase the size of the equipment and does not affect the layout of other equipment. Fifth, the guide pipe of this device has a closed structure, preventing material from jumping out during movement and injuring personnel and equipment, further improving safety and efficiency.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] Figures 1 to 5 The figure schematically illustrates a stable, non-clogging feed primary crushing air classifier according to one embodiment of the present invention. As shown, the stable, non-clogging feed primary crushing air classifier includes: an air classifier body 1, a feed nozzle 2, and a blockage remover 3;

[0030] The air classifier body 1 is provided with an air classifier cavity 100 that runs vertically through the air classifier cavity 100. The upper end of the air classifier cavity 100 is a light material outlet 101 and the lower end is a large material outlet 102. The upper side of one side of the air classifier cavity 100 is provided with a transverse mixing inlet 103 and the lower side of the other side is provided with a transverse air inlet 104.

[0031] The feed nozzle 2 includes left and right open guide pipes 20. The inner end of the guide pipe 20 is inserted into the mixing inlet 103, and an elastic seal 21 is installed at the connection gap between the two. The lower port 201 of the guide pipe 20 is connected to the air separation chamber 100. Preferably, the mixing inlet 103 is a rectangular opening, and the vertical rectangular cross-section of the lower end of the guide pipe 20 and the rectangular opening are separated.

[0032] The outer end of the guide tube 20 is inclined upward to form an inclined guide channel 200. A unclogging hole 202 communicating with the guide channel 200 is opened in the middle of the upper side of the guide tube 20. The lower end of the inner side of the unclogging hole 202 is fixedly connected to the scraper plate 22. Preferably, the inner side of the scraper plate 22 is an arc surface that cooperates with the unclogging roller 31. The small gap of the arc surface is set outside the unclogging roller 31. The beneficial effect of this setting is that it has a better cleaning effect.

[0033] The unblocking device 3 includes an unblocking roller 31 and an unblocking motor 32. The roller body 310 of the unblocking roller 31 is rotatably disposed in the unblocking hole 202 and one end of its shaft 311 is connected to the unblocking motor 32. The unblocking motor 32 is preferably a stepper motor with a hollow shaft structure, which further optimizes the size of the equipment and can withstand varying loads.

[0034] The initial crushed material enters the guide channel 200 at an incline from the upper port 203 outside the guide pipe 20. The unblocking motor 32 drives the unblocking roller 31 to rotate, thereby causing the unblocking roller 31 to push the material to move. The scraper 22 cleans away the entangled and adhered material on the unblocking roller 31.

[0035] The material enters the air separation chamber 100 for sorting through the lower port 201 and the mixing inlet 103. Under the action of the airflow from bottom to top, the light material is discharged from the light material outlet 101, and the heavier material is discharged from the large material outlet 102.

[0036] The advantages of this stable, non-clogging primary crushing air classifier are as follows: First, the air classifier body 1 and the feed nozzle 2 adopt a separate structure, and an elastic seal 21 is provided at the connection between the two, which can effectively buffer the inertial impact force of the primary crushed material, protect the feeding device, reduce the frequency of maintenance and replacement, and effectively reduce costs; Second, the feed nozzle 2 is equipped with a blockage remover 3, which can effectively prevent and remove blockages, ensuring stable and non-clogging feeding, avoiding manual blockage removal, ensuring safe operation, long continuous working time of the equipment, and high production efficiency; Third, the blockage remover 3 is equipped with a scraper 22 to prevent the blockage remover roller 31 from carrying out materials, enabling clean production; Fourth, the blockage remover 3 is set in the guide pipe 20, which does not increase the size of the equipment and does not affect the layout of other equipment; Fifth, the guide pipe 20 of this device has a closed structure, preventing materials from jumping out during movement and injuring personnel and equipment, further improving safety and efficiency.

[0037] Furthermore, the resilient seal 21 can be configured as follows:

[0038] Preferred method 1: The lower end bushing of the feed tube 20 is covered with an elastic seal 21, and the elastic seal 21 is press-fitted into the mixing inlet 103.

[0039] Preferred method 2: The edge of the mixing inlet 103 is completely covered with the elastic seal 21, and the elastic seal 21 is interference fit with the lower end of the guide tube 20.

[0040] The elastic seal 21 is preferably a rectangular rubber ring.

[0041] The beneficial effects of the two types of elastic seals 21 mentioned above are: the setting can effectively buffer the impact force, effectively protect the equipment, and seal the connection gaps, preventing dust from overflowing.

[0042] Furthermore, the feed tube 20 is a rectangular tube or a rectangular tapered tube. When it is a rectangular tapered tube, the cross-section of its lower end is smaller than that of its upper end. The beneficial effect is that this setting ensures effective feeding.

[0043] Furthermore, it also includes a three-dimensional frame structure feed support 4, which is independently installed on one side of the air separator body 1, and the feed nozzle 2 is fixedly connected to the feed support 4. Its beneficial effect is that this setting realizes the independent fixing of the feed nozzle 2, separates the impact force of the feed nozzle 2 from the sorting impact force, and effectively protects the equipment from damage.

[0044] Furthermore, each end of the unblocking roller 31 has a seated bearing 33 fitted onto its shaft 311, and the seated bearing 33 is fixedly connected to the feed support 4 via an adapter 34. The beneficial effect of this arrangement is that it enables a good unblocking rotation effect.

[0045] Preferably, the adapter 34 is a rigid metal seat, and a rubber buffer block 35 is provided between the adapter 34 and the bearing 33 to achieve small-gap floating. The beneficial effect is that this design ensures the feed nozzle 2 has a certain degree of floating performance, avoiding damage from rigid loads.

[0046] Furthermore, the light material outlet 101 is connected to a cyclone separator, and the air inlet 104 is connected to a ventilator. Preferably, the air separation chamber 100 is formed by multiple S-shaped channels connected vertically. Its beneficial effect is that this arrangement can achieve a good air separation effect.

[0047] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
