A disc-shaped partition is bolted to the inner wall of the hopper-shaped pretreatment box. A filter screen is installed at the bottom of the disc-shaped partition through a mounting groove. The power output end of the drive motor passes through one side of the lower fixed chamber and is connected to a filter cartridge located inside the lower fixed chamber. A first conveying pipe is provided at the bottom of the hopper-shaped pretreatment box, with its bottom end extending into the lower fixed chamber. Filter holes are formed around the periphery of the filter cartridge. This novel device features multiple filtration structures, providing excellent filtration of waste phosphogypsum. During water washing, it exhibits excellent uniformity in water spraying, resulting in high cleaning efficiency and suitability for widespread application.

[0003] In actual use, although the above-mentioned equipment can pre-treat industrial waste phosphogypsum, due to the different sizes and shapes of industrial waste phosphogypsum, when it is directly put into the bucket-shaped pre-treatment box for water washing, it will not only cause blockage at the feeding pipe, making it inconvenient to feed, but also cannot be quickly and completely soaked in water, thus leaving residue on the filter screen in the bucket-shaped pre-treatment box and clogging the filter screen.

[0004] Therefore, a pretreatment device for industrial waste phosphogypsum is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for industrial waste phosphogypsum to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for industrial waste phosphogypsum, comprising a hopper-shaped pretreatment box, wherein the hopper-shaped pretreatment box is provided with a feed pipe and a filter screen; a transfer hopper is installed on the feed pipe, and a crushing structure and a dredging structure are installed on the transfer hopper; and a cleaning structure is installed on the hopper-shaped pretreatment box.

[0007] The crushing structure includes a crushing box, which is mounted on a transfer hopper. A drive shaft is rotatably mounted on the crushing box, and multiple crushing blades are equidistantly mounted on the drive shaft in a ring. All of the equidistantly mounted crushing blades are rotatably mounted inside the crushing box.

[0008] The unblocking structure includes a fixed plate, which is installed on the inner wall of the transfer hopper. A connecting rod is slidably installed on the fixed plate. A guide head is installed on the bottom side of the connecting rod and is movably installed in the feed pipe. A driving hemisphere is installed on the top of the connecting rod and is in contact with the crushing blade.

[0009] A return spring is sleeved on the connecting rod. One end of the return spring is mounted on the fixed plate, and the other end of the return spring is mounted on the bottom side of the driving hemisphere.

[0010] Preferably, a first servo motor is mounted on one end of the drive shaft, a support plate is mounted on the first servo motor, and the support plate is mounted on the crushing box.

[0011] Preferably, the cleaning structure includes a rotating shaft rotatably mounted on a bucket-shaped pretreatment box, and multiple cleaning scrapers are installed on the bottom side of the rotating shaft.

[0012] Preferably, the cleaning scraper is provided with a plurality of stirring rods equidistantly arranged in a ring, and the plurality of stirring rods are rotatably installed inside the bucket-shaped pretreatment box.

[0013] Preferably, a second servo motor is mounted on the top of the rotating shaft, and a mounting bracket is mounted on the second servo motor. The mounting bracket is mounted on the bucket-shaped pretreatment box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the arrangement of a first servo motor, a drive shaft, and a crushing blade, allows industrial waste phosphogypsum to be added into a crushing chamber. The drive shaft drives the crushing blade to rotate continuously within the crushing chamber, thereby conveniently and quickly crushing the industrial waste phosphogypsum into shapes of similar size, thus facilitating faster soaking of the industrial waste phosphogypsum in the bucket-shaped pretreatment tank.

[0016] This invention, through the arrangement of a crushing blade, a driving hemisphere, a return spring, and a guide head, allows the crushing blade to contact the driving hemisphere when rotating. The driving hemisphere presses downward, causing the return spring to compress. At this time, the guide head moves downward in the feed pipe. When the crushing blade was originally driving the driving hemisphere, the guide head moves upward in the feed pipe under the action of the return spring. By having the guide head reciprocate in the feed pipe, blockage of industrial waste phosphogypsum at the feed pipe can be effectively avoided.

[0017] This invention, through the configuration of a rotating shaft, a stirring rod, a cleaning scraper, and a second servo motor, utilizes the rotating shaft to drive the cross-shaped cleaning scraper to continuously clean the filter screen, thereby effectively preventing the filter screen from being clogged by incompletely soaked industrial waste phosphogypsum. The second servo motor drives the stirring rod to rotate, thereby conveniently and quickly stirring the water and industrial waste phosphogypsum, thus facilitating the full soaking of the industrial waste phosphogypsum.

[0023] 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.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a pretreatment device for industrial waste phosphogypsum, including a hopper-shaped pretreatment box 1, a feed pipe 2 and a filter screen 3 on the hopper-shaped pretreatment box 1; a transfer hopper 7 is installed on the feed pipe 2, a crushing structure and a dredging structure are installed on the transfer hopper 7, and a cleaning structure is installed on the hopper-shaped pretreatment box 1.

[0025] To facilitate the processing of industrial waste phosphogypsum into similar sizes for rapid and thorough soaking in the bucket-shaped pretreatment tank 1, a crushing structure, including a crushing box 4, is arranged on the transfer bucket 7. The crushing box 4 is mounted on the transfer bucket 7, and a drive shaft 41 is rotatably mounted on the crushing box 4. Multiple crushing blades 44 are equidistantly mounted in a ring on the drive shaft 41, and all the equidistant crushing blades 44 are rotatably mounted inside the crushing box 4. A first servo motor 42 is mounted on one end of the drive shaft 41, and a... The support plate 43 is installed on the crushing box 4. First, industrial waste phosphogypsum is added into the crushing box 4. At the same time, the switch of the first servo motor 42 on the support plate 43 is turned on. The first servo motor 42 drives the drive shaft 41 to rotate. The drive shaft 41 drives the crushing blade 44 to rotate continuously in the crushing box 4. This allows the industrial waste phosphogypsum added to the crushing box 4 to be crushed into shapes with similar sizes quickly and easily, thereby facilitating the faster soaking speed of the industrial waste phosphogypsum in the bucket-shaped pretreatment box 1.

[0026] To prevent industrial waste phosphogypsum from clogging the feed pipe 2 and hindering material discharge, a clearing structure is installed on the transfer hopper 7. Specifically, this includes a fixed plate 5, which is mounted on the inner wall of the transfer hopper 7. A connecting rod 51 is slidably mounted on the fixed plate 5. A guide head 52 is mounted on the bottom side of the connecting rod 51 and is movably installed inside the feed pipe 2. A driving hemisphere 54 is mounted on the top of the connecting rod 51, contacting the crushing blade 44. A return spring 53 is sleeved on the connecting rod 51. One end of the return spring 53 is mounted on the fixed plate 5, and the other end is mounted on the bottom side of the driving hemisphere 54. As the crushing blade 44 rotates... When the blade 44 comes into contact with the drive hemisphere 54, it presses the drive hemisphere 54 downward. The drive hemisphere 54 drives the return spring 53 to compress, and at the same time, the drive hemisphere 54 moves downward, driving the connecting rod 51 on the fixed plate 5 to move. The connecting rod 51 drives the guide head 52 to move downward in the feed pipe 2. When the crushing blade 44 moves away from the drive hemisphere 54, under the restoring force of the return spring 53, it can easily drive the drive hemisphere 54 to move upward and return to its original position. This allows the guide head 52 to easily move upward in the feed pipe 2. Then, by the reciprocating motion of the guide head 52 in the feed pipe 2, the industrial waste phosphogypsum in the feed pipe 2 can be easily cleared, avoiding blockage.

[0027] The working principle is as follows: When using the bucket-shaped pretreatment box 1 to pretreat industrial waste phosphogypsum, the industrial waste phosphogypsum is first added to the crushing box 4. At the same time, the switch of the first servo motor 42 on the support plate 43 is turned on. The first servo motor 42 drives the drive shaft 41 to rotate. The drive shaft 41 drives the crushing blade 44 to rotate continuously in the crushing box 4, thereby quickly and easily crushing the industrial waste phosphogypsum added to the crushing box 4 into shapes with similar sizes. This facilitates the faster soaking speed of the industrial waste phosphogypsum in the bucket-shaped pretreatment box 1. At the same time, when the crushing blade 44 rotates, it will contact the drive hemisphere 54 and squeeze the drive hemisphere 54 downward. The drive hemisphere 54 drives the return spring 53 to compress. At the same time, the drive hemisphere 54 moves downward, driving the connecting rod 51 on the fixed plate 5 to move. The connecting rod 51 drives the guide head 52 to move downward in the feed pipe 2. When the crushing blade 44 moves away from the driving hemisphere 54, the restoring force of the return spring 53 can easily drive the driving hemisphere 54 to move upward and return to its original position. This allows the guide head 52 to move upward within the feed pipe 2. The guide head 52 then reciprocates within the feed pipe 2, effectively clearing the industrial waste phosphogypsum in the feed pipe 2 and preventing blockage. After the processed industrial waste phosphogypsum falls into the hopper-shaped pretreatment box 1, the switch on the second servo motor 61 is activated. The second servo motor 61 drives the rotating shaft 6 to rotate, which in turn drives the stirring rod 63 to rotate. This allows for rapid mixing of water and industrial waste phosphogypsum, ensuring thorough soaking. Simultaneously, the rotating shaft 6 drives the cross-shaped cleaning scraper 64 to continuously clean the filter screen 3, effectively preventing incompletely soaked industrial waste phosphogypsum from clogging the filter screen 3.

[0028] Example 2: Based on Example 1, to prevent incompletely soaked industrial waste phosphogypsum from accumulating and clogging the filter screen 3, and to facilitate faster mixing of the industrial waste phosphogypsum and water, a cleaning structure is arranged inside the hopper-shaped pretreatment box 1. Specifically, this includes a rotating shaft 6, which is rotatably mounted on the hopper-shaped pretreatment box 1. A second servo motor 61 is mounted on the top of the rotating shaft 6, and a mounting bracket 62 is mounted on the second servo motor 61. The mounting bracket 62 is mounted on the hopper-shaped pretreatment box 1. Multiple cleaning scrapers 64 are mounted on the bottom side of the rotating shaft 6, arranged in a cross shape and contacting the upper surface of the filter screen 3. The cleaning scrapers 64 have annular rings, etc. Multiple stirring rods 63 are installed at intervals. The multiple stirring rods 63 are rotatably installed in the hopper-shaped pretreatment box 1. After the processed industrial waste phosphogypsum falls into the hopper-shaped pretreatment box 1, the switch on the second servo motor 61 is turned on. The second servo motor 61 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the stirring rods 63 to rotate. This can conveniently and quickly stir the water and industrial waste phosphogypsum, so that the industrial waste phosphogypsum can be fully soaked. At the same time, the rotating shaft 6 drives the cross-shaped cleaning scraper 64 to continuously clean the filter screen 3, so as to effectively prevent the incompletely soaked industrial waste phosphogypsum from clogging the filter screen 3. The other features are the same as in Example 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
