Description

Technical Field

[0001] This invention relates to the field of zinc powder preparation technology, and more specifically, to a zinc powder generation system and method by spraying. Background Technology

[0002] Zinc production by injection is a commonly used zinc refining process. It involves extracting zinc from zinc ore in gaseous form and condensing it into metallic zinc. In the process of zinc production by injection, a cooling tower is usually used to cool the atomized zinc liquid coming out of the injection furnace.

[0003] Existing cooling towers generally use water as the cooling medium. However, because the cooling water contains high concentrations of minerals such as calcium and magnesium, scale easily forms on the inner walls of the cooling tower during long-term use. The scale at the bottom of the cooling tower can easily clog the circulating water pipes, so regular cleaning of the cooling tower is required. However, cleaning existing cooling towers often requires personnel to enter the cooling tower, which necessitates stopping the cooling tower's operation. Furthermore, some areas are difficult to reach, requiring specialized tools and equipment for thorough cleaning. This makes the cleaning work inconvenient, prolongs the cooling tower's downtime, and consequently affects the progress of zinc powder preparation, thus reducing the practicality of the cooling tower to some extent.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. This invention uses a motor mounted on the outer wall of the mounting column to drive a gear, which in turn drives a gear to rotate. This, in turn, drives a connecting column connected to the gear to rotate synchronously. Therefore, a scraper connected to the mounting plate and the connecting column can rotate at the bottom of the cooling tower's inner cavity. During this rotation, the scraper removes scale. Furthermore, the retraction of the electric push rod causes the mounting column to move upwards, allowing the scraper to move synchronously and expand its cleaning range on the inner wall of the cooling tower. Additionally, the scraper... During the cleaning of the inner wall of the cooling tower body, the shield is moved upward by the electric push rod 2, exposing the nozzles. At this time, the extraction pump extracts the cleaning agent from the storage tank and delivers it to the connecting column through the connecting pipe. Finally, the cleaning agent is sprayed onto the inner wall and bottom of the cooling tower body through the nozzles to assist the scraper in cleaning the cooling tower body. Therefore, the internal cleaning of the cooling tower body is achieved quickly, simplifying the cleaning process, reducing the workload of personnel, shortening the shutdown time of the cooling tower body, and ensuring the normal progress of zinc powder preparation, thereby improving the practicality of the equipment.

[0018] 2. In this invention, the electric push rod three extends and drives the mounting ring downward, causing the collection chamber to move synchronously and detach from the bottom of the cooling tower body. Then, the motor two set on one side of the collection chamber drives the rotating wheel one to rotate. Through the transmission belt, the rotating wheel two and the connecting rod rotate synchronously, thereby causing the sealing plate to flip. During the rotation of the scraper, the scraped scale is swept into the collection chamber, thus completing the unified collection of scale. By collecting the scale, it is avoided that it will accumulate on the inner wall of the cooling tower body after cleaning and cause secondary pollution, further improving the practicality of the device.

[0019] 3. This invention, by setting a connecting end between the water outlet pipe and the circulation mechanism, and cooperating with the filter screen installed inside the connecting end, can prevent scale and other impurities from entering the circulation mechanism through the water outlet pipe, thereby ensuring the normal operation of the water outlet pipe. When it is necessary to disassemble or clean the filter screen, the motor three drives the double-threaded screw to rotate, causing the moving column connecting sleeve ring two installed on the surface of the double-threaded screw to move horizontally, thereby separating the surface of the sleeve ring two from the abutment ring. Then, the electric push rod four extends to drive the locking plate to disengage from the locking groove on the surface of the rotating plate. At this time, the rotating plate is rotated, thereby rotating the filter screen to be cleaned to the other side, and rotating the unused connecting end and the filter screen between the circulation mechanism and the water outlet pipe. Then, the connecting end is fixed by the sleeve ring two. At this time, the used filter screen can be cleaned or replaced without affecting the normal connection between the circulation mechanism and the water outlet pipe. Attached Figure Description

[0040] The working principle of this invention is as follows: When cleaning the interior of the cooling tower body 1, the motor 7, located on the outer wall of the mounting column 6, drives the gear 8 to rotate. This causes the gear 9, which meshes with the gear 8, to rotate accordingly. Consequently, the connecting column 29 connected to the gear 9 rotates synchronously. Therefore, the scraper 13, connected to the connecting column 29 via the mounting plate 12, can rotate at the bottom of the inner cavity of the cooling tower body 1. During rotation, the scraper 13 scrapes off scale, and the electric push rod 15 retracts. The installation column 6 is moved upward, causing the scraper 13 to move synchronously, thereby expanding the cleaning range of the scraper 13 on the inner wall of the cooling tower body 1. In addition, during the cleaning of the inner wall of the cooling tower body 1 by the scraper 13, the shield 20 is moved upward by the electric push rod 29, so that the nozzle 18 is exposed. At this time, the extraction pump 22 extracts the cleaning agent from the storage tank 21 and delivers the cleaning agent to the connecting column 29 through the connecting pipe 23. Finally, the cleaning agent is sprayed onto the inner wall and bottom of the cooling tower body 1 through the nozzle 18 to assist the scraper 13 in cleaning the cooling tower body 1.

[0041] After the scale is scraped off by the rotating scraper 13, the electric push rod 252 extends and drives the mounting ring 254 to move down, so that the collection chamber 255 moves synchronously and detaches from the bottom of the cooling tower body 1. Then, the motor 257 set on one side of the collection chamber 255 drives the rotating wheel 258 to rotate. Through the transmission belt 259, the rotating wheel 2510 and the connecting rod 2511 rotate synchronously, thereby driving the sealing plate 2512 to flip. During the rotation of the scraper 13, the scraped scale is swept into the collection chamber 255, thus completing the unified collection of scale.

[0042] By using the connecting end 268 between the water outlet pipe 27 and the circulation mechanism 3, and with the filter screen 269 installed inside the connecting end 268, scale and other impurities can be prevented from entering the circulation mechanism 3 through the water outlet pipe 27, thus ensuring the normal operation of the water outlet pipe 27. When it is necessary to disassemble or clean the filter screen 269, the motor 262 drives the double-threaded screw 263 to rotate, causing the moving column 264 installed on the surface of the double-threaded screw 263 to move horizontally, thereby allowing the sleeve ring 265 to move horizontally, and thus the sleeve ring 265 and the abutment ring 265 to move horizontally. The surface of 610 is separated, and then the electric push rod 2611 extends to drive the snap plate 2612 to disengage from the snap groove on the surface of the rotating plate 267. At this time, the rotating plate 267 is rotated, thereby rotating the filter screen 269 to be cleaned to the other side, and rotating the unused connecting end 268 and the filter screen 269 between the circulation mechanism 3 and the water outlet pipe 27. Then, the connecting end 268 is fixed by the connecting ring 265. At this time, the used filter screen 269 can be cleaned or replaced without affecting the normal connection between the circulation mechanism 3 and the water outlet pipe 27.
