Description

Technical Field

[0001] This utility model relates to the field of molecular sieve processing technology, specifically to a molecular sieve processing waste cleaning device. Background Technology

[0002] Molecular sieves, as important adsorbents and catalysts, are widely used in many fields such as chemical, petroleum, and environmental protection. During the processing of molecular sieves, materials containing waste residue are generated. The presence of this waste residue not only affects the quality of molecular sieve products, but may also damage subsequent production equipment. Therefore, it is necessary to clean up the waste residue in a timely and effective manner.

[0003] Traditional methods for cleaning up waste residue from molecular sieve processing often involve manual screening or water washing. These methods are inefficient, incomplete, and wasteful of water resources. In particular, while water washing can remove some impurities from the waste residue, it generates a large amount of wastewater containing chemicals, which can cause serious environmental pollution if not properly treated.

[0004] A search revealed a molecular sieve processing waste cleaning device disclosed in announcement number "CN216937534U". Its technical solution involves using a high-pressure cleaning fan to generate strong air, which is then delivered to a U-shaped high-pressure duct. Simultaneously, the strong air blows through the inverted U-shaped duct around the inside of the tank, effectively cleaning the residual waste and small amounts of molecular sieve from the inner wall using the high-pressure airflow. This eliminates the need for water-based high-pressure cleaning, further reducing water waste and improving tank cleaning efficiency. While the device design considers waste cleaning efficiency, it does not adequately address the potential dust dispersion issues during high-pressure airflow cleaning, such as the open design of the inlet pipe, gaps between the outlet and the hopper, and the possibility of the strong high-pressure air carrying material dust from the tank into the surrounding environment, thus impacting environmental conditions. Therefore, we propose a molecular sieve processing waste cleaning device. Utility Model Content

[0016] Example 1

[0017] like Figures 1 to 3As shown, this utility model discloses a molecular sieve processing waste cleaning device. The technical solution includes a tank 1, with three support legs 18 arranged in a circumferential array at equal intervals at the bottom of the tank 1. A feed pipe 2 is provided at one end of the top of the tank 1, and an electric gate valve 17 is provided at the bottom of the feed pipe 2. The electric gate valve 17 is provided to prevent material backflow during subsequent screening. The bottom of the tank 1 has a conical structure, and a first electric valve 12 is provided in the middle of the discharge pipe at the bottom center of the tank 1. A conical screen 10 is provided directly above the first electric valve 12, and the conical screen 10 is fixedly installed on the upper surface of an annular fixing plate 11 provided in the middle of the inner side of the tank 1. Waste discharge pipes 15 are respectively inclined at the left and right ends of the annular fixing plate 11, and the waste discharge... One end of the discharge pipe 15 is connected to the interior of the tank 1. A third electric valve 20 is installed at the end of the waste discharge pipe 15 near the tank 1. The other end of the waste discharge pipe 15 is connected to a connecting vertical pipe 7. A filter assembly 8 is threaded onto the top of each connecting vertical pipe 7. The filter assembly 8 consists of a filter sleeve 81, a sealing ring 82, and filter plates 83. Two filter sleeves 81 are provided, each threaded onto the top of the connecting vertical pipe 7. The sealing ring 82, located in the middle of the inner side of each filter sleeve 81, is in movable contact with the top of the connecting vertical pipe 7. Filter plates 83 are arranged in an evenly spaced array on the top inner side of each filter sleeve 81. The filter plates 83 can filter dust carried by the high-pressure gas entering the connecting vertical pipe 7. The filter sleeve 81 is threaded to the top of the connecting vertical pipe 7, which facilitates subsequent maintenance of the filter plate 83 inside the filter sleeve 81 by the operator. The sealing ring 82 improves the sealing between the filter sleeve 81 and the connecting vertical pipe 7. A second electric valve 16 is installed at the bottom of the connecting vertical pipe 7. A connecting shaft 9 is installed above the conical screen 10. The conical screen cleaning plate 19, which is fixedly installed at the bottom of the outer side of the connecting shaft 9, is in contact with the surface of the conical screen 10. A scraping assembly 6 is installed in the middle of the connecting shaft 9. The scraping assembly 6 consists of a connecting rod 61, a scraper sleeve 62, a compression spring 63, and a tank wall scraper 64. The scraper sleeve 62 is located in the middle of one side of the connecting shaft 9. The middle and bottom of one end of the scraper sleeve 62 are connected to the connecting shaft through the connecting rod 61. 9. A fixed connection is established. A tank wall scraper 64 is slidably installed in the guide groove at the middle of the other end of the scraper sleeve 62. One end of the tank wall scraper 64 is in movable contact with the inner wall of the tank body 1. Compression springs 63 are respectively provided at the middle and upper and lower ends of the other end of the tank wall scraper 64. The other ends of the compression springs 63 are fixedly connected to the inner wall of the guide groove in the middle of the scraper sleeve 62. The scraper sleeve 62 is fixedly connected to the connecting shaft 9 through a connecting rod 61. The connecting rod 61 can stir the material in the tank body 1. Furthermore, the tank wall scraper 64, which is slidably installed in the guide groove at the middle of the other end of the scraper sleeve 62, always maintains close contact with the inner wall of the tank body 1 under the action of the compression springs 63. In this way, as the tank wall scraper 64 rotates with the scraper sleeve 62, it can continuously scrape off the waste residue adhering to the inner wall of the tank body 1.To prevent waste residue from adhering and accumulating on the inner wall of tank 1, the top of connecting shaft 9 is rotatably connected to the top center of tank 1. A motor 4 is installed above connecting shaft 9 and is fixedly mounted on the top of tank 1. The output shaft end of motor 4 is fixedly connected to the top of connecting shaft 9. A blowing unit 5 is installed on the top of tank 1. The blowing unit 5 includes a high-pressure air pump 51, an air inlet pipe 52, an exhaust pipe 53, an annular connecting pipe 54, and a blowing nozzle 55. The high-pressure air pump 51 is fixedly mounted on one end of the top of tank 1. The air inlet end of the high-pressure air pump 51 is equipped with an air inlet pipe 52, and the exhaust end of the high-pressure air pump 51 is equipped with an exhaust pipe 53. The other end of the exhaust pipe 53 is connected to an annular connecting pipe 54 installed on the top of the outer side of tank 1. The internal structure of the connecting pipe 54 is interconnected. Extension pipes arranged in a circumferential array at equal intervals on the inner side of the annular connecting pipe 54 are fixedly connected to the blowing nozzles 55 located at the top inner side of the tank body 1. By activating the high-pressure air pump 51, air is drawn in through the air inlet pipe 52, compressed, and then delivered to the annular connecting pipe 54 through the exhaust pipe 53. The extension pipes arranged in a circumferential array at equal intervals on the inner side of the annular connecting pipe 54 deliver the compressed air to the blowing nozzles 55 at the top inner side of the tank body 1. The blowing nozzles 55 spray high-pressure gas into the tank body 1, agitating the materials and waste residue inside. This assists the screening process, ensuring more thorough material screening, and also blows off materials adhering to the cone. To improve the cleaning effect on the waste residue on the conical screen 10 and the inner wall of the tank 1, the system also includes an extension rod 13 and a tank bottom scraper 14. The extension rod 13 is located at the center of the inner side of the conical screen 10, and the top end of the extension rod 13 passes through a through hole at the center of the top of the conical screen 10 and is fixedly connected to the bottom of the connecting shaft 9. The tank bottom scraper 14 is fixedly installed at the bottom of the extension rod 13, and the other side surface of the tank bottom scraper 14 is in contact with the inclined surface of the inner bottom of the tank 1. The top end of the extension rod 13 passes through a through hole at the center of the top of the conical screen 10 and is fixedly connected to the bottom of the connecting shaft 9. The tank bottom scraper 14 is fixedly installed at the bottom of the extension rod 13. When the connecting shaft 9 rotates, it drives the tank bottom scraper 14 to rotate, thus cleaning the waste residue on the inner bottom of the tank 1. The inclined surface is cleaned to prevent waste residue from accumulating at the bottom of tank 1. Opening the first electric valve 12 allows the filtered material to be discharged from the discharge pipe at the center of the bottom of tank 1. A controller 3 is installed at the bottom front of tank 1. The output of controller 3 is electrically connected to the inputs of motor 4, high-pressure air pump 51, first electric valve 12, second electric valve 16, electric gate valve 17, and third electric valve 20. The input of controller 3 is electrically connected to the output of an external power supply. The controller 3 allows operators to easily control motor 4, high-pressure air pump 51, first electric valve 12, second electric valve 16, electric gate valve 17, and third electric valve 20.

[0018] The working principle of this utility model is as follows: First, the electric gate valve 17 at the bottom of the feed pipe 2 is opened, allowing the molecular sieve material containing waste residue to be conveyed into the tank 1 through the feed pipe 2. After entering the tank 1, the material falls onto the conical screen 10. At this time, the electric gate valve 17 closes to prevent backflow of material during subsequent operations. Then, the motor 4 is started, and the output shaft of the motor 4 drives the connecting shaft 9 to rotate. Since a conical screen cleaning plate 19 is fixedly installed at the bottom outer side of the connecting shaft 9, and the conical screen cleaning plate 19 is in active contact with the surface of the conical screen 10, the rotation of the connecting shaft 9 will cause the conical screen cleaning plate 19 to perform circular motion on the surface of the conical screen 10, cleaning the conical screen 10 in real time and preventing waste residue blockage. The screen mesh is open, and the material is screened on the conical screen 10. Fine particles that meet the particle size requirements pass through the conical screen 10 and fall to the bottom of the tank 1, while large particles of waste residue that do not meet the particle size requirements remain on the conical screen 10. Secondly, since the scraper sleeve 62 is fixedly connected to the connecting shaft 9 through the connecting rod 61, the connecting rod 61 can stir the material in the tank 1. Furthermore, the tank wall scraper 64, which is slidably installed in the guide groove at the other end of the scraper sleeve 62, always maintains close contact with the inner wall of the tank 1 under the action of the compression spring 63. In this way, as the tank wall scraper 64 rotates with the scraper sleeve 62, it can continuously scrape off the waste residue attached to the inner wall of the tank 1, preventing the waste residue from adhering and accumulating on the inner wall of the tank 1. In addition, the top of the extension rod 13 passes through the central through hole at the top of the conical screen 10 and is fixedly connected to the bottom of the connecting shaft 9. A tank bottom scraper 14 is fixedly installed at the bottom of the extension rod 13. When the connecting shaft 9 rotates, it drives the tank bottom scraper 14 to rotate, cleaning the inclined surface of the bottom inside the tank 1 and preventing waste residue from accumulating at the bottom of the tank 1. Then, during the operation of the device, the high-pressure air pump 51 in the blowing unit 5 can be started. The high-pressure air pump 51 draws in air through the air inlet pipe 52, and after compression, it is delivered to the annular connecting pipe 54 through the exhaust pipe 53. The extension pipes arranged in an evenly spaced circular array inside the annular connecting pipe 54 deliver the compressed air to the blowing nozzle 55 at the top inside the tank 1. The blowing nozzle 55 blows air into the tank 1. High-pressure gas is ejected from the pump to blow away the material and waste residue inside the tank 1. This assists in the screening process, making the material screening more thorough. It also blows off the waste residue adhering to the conical screen 10 and the inner wall of the tank 1, improving the cleaning effect. Finally, during the waste residue discharge stage, the third electric valve 20 on the waste residue discharge pipe 15 is opened to discharge the unfiltered large particles of waste residue on the conical screen 10 into the interior of the connecting vertical pipe 7. A filter assembly 8 is threaded on the top of the connecting vertical pipe 7. The filter plate 83 in the filter assembly 8 can filter the dust carried by the high-pressure gas. Then, the high-pressure air pump is turned off, and the second electric valve 16 at the bottom of the connecting vertical pipe 7 is opened to discharge the material residue.
