Description

Technical Field

[0001] The utility model relates to the technical field of silicon powder preparation, in particular to a cleaning tool for a disc valve. Background Art

[0002] The valve used for 802 silicon powder discharge is a disc valve. The disc valve operates on the principle of leverage. The cylinder valve is connected to the valve shaft, pushing the valve disc to move to realize valve switching. A large amount of silicon powder or foreign matter accumulation in the disc valve cavity will cause the disc valve to become stuck or even unable to operate, directly affecting the silicon powder under process.

[0003] At present, the main methods for cleaning disc valve jams are:

[0004] 1. Forcibly knock on the disc valve arm to use external force to open and close.

[0005] 2. If knocking on the disc valve is ineffective, disconnect the purge port of the disc valve and directly use the disc valve air source to blow out the silicon powder.

[0006] Hazards: External force striking the disc valve can easily damage it, reducing its service life. Silicon dust released during the purge of the valve cavity using the air supply pipe can cause damage to the employee's face and organs, and the dust cannot be collected, making it difficult for employees to clean up.

[0007] Using the air supply tube to reach into the valve cavity to clean the silicon powder cannot ensure that the silicon powder in the valve cavity is completely cleaned out. The residual silicon powder may continue to affect the normal operation of the disc valve. Utility Model Content

[0008] In order to solve the above technical problems, the utility model provides a cleaning tool for a disc valve, wherein a purge pipe is inserted into the valve cavity of the disc valve through a connecting pipe, and the other end of the purge pipe is externally connected to nitrogen. By introducing nitrogen, silicon powder in the valve cavity of the disc valve is blown into a collection box through the connecting pipe and the collecting pipe, thereby avoiding external force hitting the disc valve, improving the service life of the disc valve, and effectively collecting the silicon powder in the disc valve, thereby avoiding overflow of silicon powder in the process of cleaning the valve cavity of the disc valve to cause environmental pollution and saving the time of relevant personnel in cleaning the site.

[0042] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a cleaning tool for a disc valve 8, comprising: a connecting pipe 1, a collecting pipe 2, a collecting box 3 and a purge pipe 5. One end of the connecting pipe 1 is used to communicate with the disc valve 8, and the other end is sealed. One end of the collecting pipe 2 is connected to the connecting pipe 1. The collecting box 3 is connected to the other end of the collecting pipe 2. One end of the purge pipe 5 extends into the valve cavity of the disc valve 8 through the connecting pipe 1, and the other end of the purge pipe 5 is connected to the gas source. When the purge pipe 5 is connected, the gas flow direction in the purge pipe 5 is opposite to the mixed gas flow direction in the connecting pipe 1, which facilitates the entry of silicon powder into the collecting box 3.

[0044] During use, the connecting pipe 1 is connected to the disc valve 8, and one end of the purge pipe 5 extends into the connecting pipe 1 through the sealed end of the connecting pipe 1 and extends into the valve cavity of the disc valve 8. One end of the collection pipe 2 is connected to the connecting pipe 1, and the other end of the collection pipe 2 is connected to the collection box 3.

[0045] During silicon powder cleaning, nitrogen enters the valve cavity of disc valve 8 through purge pipe 5, purging the silicon powder from the cavity. During the purge, the nitrogen flow in purge pipe 5 is opposite to the flow of the silicon powder. This allows the silicon powder to flow through connecting pipe 1 into collection pipe 2. The continuous flow of nitrogen then allows the silicon powder in collection pipe 2 to enter collection box 3.

[0046] In one embodiment, in order to prevent excessive pressure in the collecting box 3 during the purging process, an exhaust valve 4 is provided on the top of the collecting box 3 .

[0047] The above structure is used to clean the silicon powder in the disc valve 8, effectively preventing external force from knocking on the disc valve 8, and improving the service life of the disc valve 8. At the same time, it effectively collects the silicon powder in the disc valve 8, preventing the silicon powder from overflowing during the knocking process to cause environmental pollution and saving the time of relevant personnel in cleaning the site.

[0048] In one embodiment, Figure 1 As shown, in order to facilitate the connection between the connecting pipe 1 and the disc valve 8 , one end of the connecting pipe 1 has a flange 11 , and is connected to the disc valve 8 via the flange 11 .

[0049] In one embodiment, to prevent silicon powder in the collection box 3 from flowing back into the disc valve 8 after the nitrogen supply is stopped, the axis of the connecting pipe 1 is perpendicular to the axis of the collection pipe 2. The other end of the collection pipe 2 is connected to the top of the collection box 3.

[0050] In one embodiment, Figure 1 and Figure 2 As shown, in order to make the gas sent into the connecting pipe 1 by the purge pipe 5 more evenly fill the valve cavity of the disc valve 8, one end of the purge pipe 5 located in the connecting pipe 1 is coaxially arranged with the connecting pipe 1.

[0051] In one embodiment, Figure 1 and Figure 2 As shown, in order to further prevent the silicon powder in the collection box 3 from overflowing, a filter assembly 6 is provided in the collection box 3 corresponding to the exhaust valve 4. The filter assembly 6 can be a filter screen or a bag dust removal assembly. Both the filter screen and the bag dust removal assembly are existing designs, and their specific structures are not repeated here.

[0052] In one embodiment, Figure 1 As shown, in order to facilitate the connection between the purge pipe 5 and the gas source pipeline, a connecting joint 7 is provided at one end of the purge pipe 5 .

[0053] In one embodiment, in order to increase the service life of the cleaning device, the connecting pipe 1, the collecting pipe 2 and the collecting box 3 are all made of carbon steel. In order to facilitate connection with the air source, the purge pipe 5 is a hose.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
