Description
Technical Field
[0001] This utility model relates to the field of potassium perchlorate processing technology, and in particular to an integrated machine for potassium perchlorate crystallization and drying. Background Technology
[0002] Electrostatic spraying is a coating method that utilizes the principle of corona discharge to negatively charge atomized paint under a high-voltage DC electric field, causing it to be adsorbed onto the surface of a positively charged substrate and discharged. Electrostatic spraying is used as an auxiliary process in the manufacturing of shovel hangers. However, this electrostatic spraying process generates a large amount of dust within the workshop. To avoid environmental pollution from this dust, dust collectors are used to collect and treat it.
[0003] For example, Chinese patent CN217745803U discloses a continuous production equipment for coarse-grained potassium perchlorate, which includes a batching tank, a centrifuge tank, a drying device, a vibrating screen, a storage tank, and a siphon. The centrifuge tank is installed below the batching tank, the drying device is installed below the centrifuge tank, the vibrating screen is installed below the drying device, and the storage tank is installed on one side below the batching tank. The storage tank is connected to the batching tank through a siphon.
[0004] In the aforementioned patent, although the problem of low raw material utilization is solved by using fine-particle potassium perchlorate as the crystal nucleus for coarse-particle potassium perchlorate crystallization, the speed of crystal feeding is only buffered by the sliding table during crystal drying. The contact time between the crystal and hot air is short, the moisture evaporation effect is limited, and there is still a lot of moisture residue inside the crystal, which reduces the overall drying effect. Utility Model Content

Therefore, this invention proposes an integrated potassium perchlorate crystallization and drying machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a potassium perchlorate crystallization and drying integrated machine, comprising a frame, a crystallizer assembly fixedly connected to the top of the frame, a guide tube connected to the bottom of the crystallizer assembly, a crushing cylinder fixedly connected to one end of the guide tube, a motor fixedly connected to one side of the crushing cylinder, a crushing roller fixedly connected to one end of the output shaft of the motor, the crushing roller and the crushing cylinder being rotatably connected, an internal hopper provided at the top of the crushing roller, one side of the internal hopper being fixedly connected to the inner wall of the crushing cylinder, and a guide tube fixedly connected to the bottom of the crushing cylinder, one end of the guide tube penetrating the side wall of the frame, an outer cylinder fixedly connected to the inner wall of the frame, an inner cylinder rotatably connected inside the outer cylinder, a drying tube inserted inside the inner cylinder, and a heater fixedly connected to one end of the drying tube after penetrating the side wall of the frame.

[0008] Preferably, the bottom of the outer cylinder is provided with a collection hopper, the bottom of the collection hopper has a discharge port, and one side of the collection hopper is fixedly connected to the inner wall of the frame.

The outer ring surface of the lead screw is fixedly connected to the inner cylinder, and the lead screw is rotatably connected to the outer cylinder.
[0011] Preferably, the lead screw is connected to a connector via a thread, an electric push rod is fixedly connected to one side of the connector, and a connecting frame is fixedly connected to one end of the electric push rod.
[0012] Preferably, a cleaning ring is fixedly connected to one side of the connecting frame, and the cleaning ring is movably connected to the inner wall of the inner cylinder.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, one end of the guide tube is fixedly connected to the crushing cylinder, and the crushing roller is rotatably connected to the crushing cylinder. The crystals generated inside the crystallizer assembly are guided by the guide tube and enter the crushing cylinder, where they are crushed by the two crushing rollers. Then, they are sent into the inner cylinder through the guide tube. The crushing rollers can reduce the volume of the crystals, and the crushed crystal particles have a larger specific surface area, making it easier for moisture to diffuse from the inside to the surface, thereby accelerating the overall drying speed. Hot air is introduced into the inner cylinder through the drying tube, and the crystals are dried during centrifugation, allowing the crystals to be in full contact with the hot air for a long time, reducing the residual moisture inside the crystals, thereby ensuring the drying effect of the crystals.
[0015] 2. In this utility model, the connector and the lead screw are connected by a thread, and an electric push rod is fixedly connected between the connector and the connecting frame. When the lead screw rotates, the connector moves along the lead screw, driving the connecting frame and the cleaning ring to move synchronously with the connector. When the cleaning ring moves, it scrapes the inner wall of the inner cylinder. The distance between the connector and the connecting frame can be adjusted by the electric push rod, which makes it easier to increase the contact range between the cleaning ring and the inner wall of the inner cylinder, thereby ensuring the scraping effect on the inner wall of the inner cylinder and reducing the adhesion of crystals on the inner wall of the inner cylinder.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: Refer to Figures 1-5 As shown: A potassium perchlorate crystallization and drying integrated machine includes a frame 2. A crystallizer assembly 1 is fixedly connected to the top of the frame 2. A guide tube 4 is fixedly connected to the bottom of the crystallizer assembly 1. A crushing cylinder 7 is fixedly connected to one end of the guide tube 4. A motor 18 is fixedly connected to one side of the crushing cylinder 7. A crushing roller 20 is fixedly connected to one end of the output shaft of the motor 18. The crushing roller 20 is rotatably connected to the crushing cylinder 7. An internal hopper 17 is provided at the top of the crushing roller 20. One side of the internal hopper 17 is fixedly connected to the inner wall of the crushing cylinder 7. A guide tube 19 is fixedly connected to the bottom of the crushing cylinder 7. One end of the guide tube 19 penetrates the side wall of the frame 2. An outer cylinder 6 is fixedly connected to the inner wall of the frame 2. An inner cylinder 11 is rotatably connected inside the outer cylinder 6. A drying tube 3 is inserted inside the inner cylinder 11. One end of the drying tube 3 penetrates the side wall of the frame 2 and is fixedly connected to a heater 9. One side of the heater 9 is fixedly connected to the inner wall of the frame 2. A heating tube is fixedly connected inside the heater 9. A fan 8 is fixedly connected to one side of the heater 9. One side of the fan 8 is fixedly connected to the inner wall of the frame 2.
[0025] The frame 2 supports the bottom of the crystallizer assembly 1, and the guide tube 4 guides the crystals discharged from the crystallizer assembly 1, allowing them to smoothly enter the crushing cylinder 7. The built-in hopper 17 collects the crystals entering the crushing cylinder 7, allowing them to enter the gap between the two crushing rollers 20. The motor 18 provides power for the rotation of the crushing rollers 20. The rotation of the two crushing rollers 20 breaks down the crystals, thereby changing their volume and preventing them from becoming too large. The fan 8 accelerates the airflow inside the heater 9, heating the air entering the heater 9. The drying tube 3 guides the airflow, allowing the hot air to smoothly enter the inner cylinder 11 to heat and dry the centrifuged crystals, reducing residual moisture inside the crystals.
[0026] Example 2: Figures 1-4As shown, a collection hopper 10 is provided at the bottom of the outer cylinder 6. The collection hopper 10 has a discharge port at its bottom, and one side of the collection hopper 10 is fixedly connected to the inner wall of the frame 2. A pulley assembly 12 is provided at one end of the outer cylinder 6. The output shaft of motor 5 is fixedly connected to one side of one of the pulleys of the pulley assembly 12. The bottom of motor 5 is fixedly connected to the outer cylinder 6. A lead screw 21 is inserted into one side of the other pulley of the pulley assembly 12. One end of the lead screw 21 passes through the side wall of the outer cylinder 6 and the inner cylinder 11. The outer ring surface of the lead screw 21 is fixedly connected to the inner cylinder 11. The lead screw 21 is rotatably connected to the outer cylinder 6. The lead screw 21 is connected to a connector 13 by a thread. An electric push rod 15 is fixedly connected to one side of the connector 13. A connecting frame 16 is fixedly connected to one end of the electric push rod 15. A cleaning ring 14 is fixedly connected to one side of the connecting frame 16. The cleaning ring 14 is movably connected to the inner wall of the inner cylinder 11.
[0027] The material discharged from the outer cylinder 6 can be collected by the collection hopper 10. The outer cylinder 6 can support the bottom of the motor 5. The motor 5 can provide power for the operation of the pulley assembly 12, driving the inner cylinder 11 to rotate inside the outer cylinder 6, thereby achieving centrifugal processing of the crystals. The inner cylinder 11 is fixedly connected to the lead screw 21, which can achieve synchronous rotation of the inner cylinder 11 and the lead screw 21. The threaded connection between the lead screw 21 and the connecting member 13 can drive the connecting member 13 to move along the lead screw 21, thereby changing the position of the connecting frame 16 and the electric push rod 15 inside the inner cylinder 11. The distance between the connecting member 13 and the connecting frame 16 can be adjusted by the electric push rod 15, which facilitates the adjustment of the range of movement of the cleaning ring 14 inside the inner cylinder 11. The movement of the cleaning ring 14 can scrape the inner wall of the inner cylinder 11, thereby achieving cleaning of the inner wall of the inner cylinder 11.
[0028] The operating method and working principle of this device are as follows: First, the high-temperature electrolyte in the electrolyte circulation tank is directly fed into the crystallizer assembly 1. The liquid is stirred using the stirring structure inside the crystallizer assembly 1. During the stirring process, cooling and crystallization occur. The liquid is then discharged through the pipe at the bottom of the crystallizer assembly 1. Next, the valve on the guide pipe 4 is opened, and potassium perchlorate crystals are fed into the crushing cylinder 7 through the guide pipe 4. After being guided by the built-in hopper 17, they enter the gap between the two crushing rollers 20. The motor 18 drives the crushing rollers 20 to rotate, crushing the potassium perchlorate crystals into smaller particles. Smaller particles have a larger specific surface area, making it easier for moisture to diffuse from the inside of the particles to the surface, thus accelerating the drying speed. The crushed crystal particles enter the inner cylinder 11 through the guide pipe 19. The rear motor 5 drives one of the pulleys of the pulley assembly 12 to rotate, and the other pulley rotates under the drive of the belt. At this time, the inner cylinder 11 and the lead screw 21 rotate synchronously to centrifuge the particles. During centrifugation, the fan 8 sends air into the heater 9. After the air is heated, it enters the inner cylinder 11 through the drying pipe 3 to heat and dry the particles inside the inner cylinder 11. When the lead screw 21 rotates with the inner cylinder 11, it can drive the connecting piece 13 to move along the lead screw 21 under the action of the thread, and drive the cleaning ring 14 to rotate and move inside the inner cylinder 11 to scrape the inner wall of the inner cylinder 11. When the connecting piece 13 moves to the end of the lead screw 21, the electric push rod 15 drives the connecting frame 16 to move. The cleaning ring 14 moves synchronously with the connecting frame 16 to continue scraping the inner wall of the inner cylinder 11.
