Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and more specifically to a high-throughput silicon powder filtration device. Background Technology

[0002] High-throughput silicon powder filtration systems are devices specifically designed to process gaseous or liquid fluids containing fine particulate matter, particularly silicon powder. These systems are critical in semiconductor manufacturing, solar panel production, and other industries requiring highly pure materials. Their primary function is to remove particles such as silicon powder from fluids to ensure the quality of the final product and reduce wear and tear on equipment in subsequent processing steps.

[0003] Chinese patent application number 202120426787.3 discloses an activated carbon filter. The internal structure of the filter cylinder contains titanium rod filter elements and titanium filter plates. The cylinder is also encased in a jacket, forming a hollow cavity between the jacket and the cylinder. The jacket has a media outlet at its upper end and a media inlet at its lower end, connected by a high-temperature heat transfer medium circulation system and a low-temperature heat transfer medium circulation system. The cylinder has a liquid inlet; the upper end cap has a liquid outlet and a pressure gauge port; and the lower end cap has a residual liquid outlet. However, this activated carbon filter has the following problems during use:

[0004] 1. Because high-throughput silica powder often has high hardness and sharpness, it can cause wear to the filter element. Therefore, it needs to be cleaned to avoid the accumulation of high-throughput silica powder from affecting the filter element. However, this device lacks a structure that can effectively clean the filter element.

[0005] 2. Although some filter cartridges have an airflow cleaning structure at the top, the airflow from the top cannot effectively clean the bottom deposits because there are more deposits on the bottom of the filter cartridge than on the top, resulting in reduced cleaning efficiency and making it inconvenient to replace the filter cartridge.

[0006] Therefore, it is necessary to propose a high-throughput silicon powder filtration device to solve the above problems. Utility Model Content

[0007] To address the above problems, this utility model provides a high-throughput silicon powder filtration device; it enhances the cleaning of the filter element and facilitates the disassembly and assembly of the filter element.

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.

[0026] Please see Figure 1-3A high-throughput silicon powder filtration device includes a tank 101. The outer wall of the tank 101 is connected to a discharge pipe 102 extending into the interior and an air inlet pipe 103. The air inlet pipe 103 allows material to enter, and the material passes through filter elements 104 before exiting through the discharge pipe 102. The air inlet pipe 103 is located at the bottom of the discharge pipe 102. Filter elements 104 are arranged at equal intervals between the discharge pipe 102 and the air inlet pipe 103. Each filter element 104 consists of a filter screen support and filter cloth. The filter screen support is shaped like a quincunx. A threaded pipe 105 is connected to the bottom of each filter element 104, and branch pipes are connected to the top of the air inlet pipe 103 at equal intervals. 106, the top of the branch pipe 106 is connected to a base plate 107, the top of the base plate 107 is connected to a lower threaded pipe 108 coaxially arranged with the upper threaded pipe 105, the threads on the upper threaded pipe 105 and the lower threaded pipe 108 are mutually engaged, so that the lower connecting pipe 109 can be connected to the lower threaded pipe 108 and the upper threaded pipe 105 at the same time, the outer ring surfaces of the lower threaded pipe 108 and the upper threaded pipe 105 are provided with mutually engaging external threads, the lower connecting pipe 109 is threadedly connected to the outer ring surface of the lower threaded pipe 108, and the outer ring surface of the lower connecting pipe 109 is provided with a hexagonal part, which is convenient to rotate the lower connecting pipe 109 by using a wrench;

[0027] refer to Figure 3 The top of the base plate 107 is connected to a one-way nozzle 110 coaxially arranged with the lower threaded pipe 108. The one-way nozzle 110 is only connected during cleaning and is used to spray air upwards to clean the filter element 104. Preferably, when the air is sprayed, the top discharge pipe 102 is closed. A guide ring 111 is connected between the one-way nozzle 110 and the lower threaded pipe 108. The guide ring 111 guides the airflow.

[0028] Specifically, refer to Figure 3 The bottom of the discharge pipe 102 is connected to a threaded post 112, and the upper connecting pipe 113 is connected by a thread and moves movably on the threaded post 112. The upper connecting pipe 113 is threaded on the outer ring surface of the threaded post 112. The bottom of the upper connecting pipe 113 is provided with a beveled part 114. When the upper connecting pipe 113 moves downward, it will squeeze the filter element 104 downward.

[0029] Specifically, refer to Figure 3The top of the filter element 104 is connected to an upper connecting plate 115. The upper connecting plate 115 and the top conical tube 116 serve a positioning function. The top of the upper connecting plate 115 is connected to a conical tube 116 that mates with the inclined part 114. When installing the filter element 104, the filter element 104 is positioned on the axis of the branch tube 106 and the threaded column 112. Then, the lower connecting tube 109 is rotated to install the upper threaded tube 105 and the lower threaded tube 108 together. Then, the upper connecting tube 113 is rotated downwards, and the conical tube 116 is squeezed by the inclined part 114 at the bottom of the upper connecting tube 113, thereby pressing it onto the sealing ring 118 on the upper connecting plate 115.

[0030] Specifically, refer to Figure 3 The bottom of the threaded post 112 is connected to an annular plate 117, and the top of the annular plate 117 is connected to a sealing ring 118. Preferably, a sealing ring 118 is provided at the top of the thread on the outer wall of the upper threaded tube 105 to improve the sealing performance of the connection.

[0031] Specifically, refer to Figure 3 The top of the upper connecting plate 115 is connected to a sealing ring 118, which is located outside the tapered tube 116. Preferably, sealing rings 118 are provided at the positions where the upper threaded tube 105 and the lower threaded tube 108 meet, in order to improve the sealing performance of the connection.

[0032] Specifically, refer to Figure 1 The bottom of the tank 101 is connected to a feed pipe 119 and a slag discharge pipe 120. Particles that do not pass through the filter element 104 will be discharged from the slag discharge pipe 120 at the bottom. The top of the tank 101 is connected to an exhaust port, a spray port, an air inlet, a spare port, a liquid level switch port, and a remote pressure gauge port. The spray port is used to clean the inside, and then airflow is sprayed into the inside through the air inlet to accelerate the evaporation of internal moisture.

[0033] Specifically, the filter element 104 is composed of a filter screen support and a filter cloth, and preferably, the filter screen support is in the shape of a plum blossom.

[0034] In this embodiment, liquid or gaseous raw materials enter the tank 101 through the air inlet pipe 103, and are then discharged from the outlet pipe 102 after being filtered by the filter element 104. When cleaning the filter element 104, the airflow sprayed from the one-way nozzle 110 will impact the filter element 104 from the bottom, thus achieving a cleaning effect.

[0035] When replacing the old filter element 104, rotate the upper connecting tube 113 upward to disengage it from the conical tube 116. Then rotate the lower connecting tube 109 downward to disengage it from the upper threaded tube 105. At this point, the old filter element 104 can be removed and replaced with the new filter element 104.
