Description

Technical Field

[0001] This utility model relates to the field of instrument misalignment research technology, and in particular to an instrument maintenance tool. Background Technology

[0002] Thermometers, pressure gauges and other instruments are important monitoring equipment for the stable operation of polysilicon production. These instruments sometimes become inaccurate after use. The inventors discovered the cause of the inaccuracy after a lot of research. For example, in the slurry system, the accumulation of slag at the level gauge connection point can cause the level gauge to become inaccurate (the level gauge itself is not damaged).

[0003] The conventional method to solve the problem of slag accumulation and blockage is to use nitrogen to purge and clean it. However, there is a risk of material splashing during the cleaning process, which poses a great safety hazard. When the blockage is severe, the production line must be shut down for cleaning before the material can be fed back in, which seriously affects the stable operation of production.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0040] The embodiments of this utility model will be described in detail below.

[0041] Example

[0042] See Figure 1 This embodiment provides an instrument maintenance tool, including a connector 1, a drill bit 2, a drill rod 3, a slag discharge auger 4, and a sealing structure.

[0043] Connector 1 is used to connect to instrument pipe 7. Connector 1 is a flange, with a connection hole 11 at its center and a slag discharge port 12 at its eccentric part that can communicate with instrument pipe 7. Slag discharge port 12 is connected to slag discharge valve 13. Slag discharge valve 13 is a knife gate valve.

[0044] Drill bit 2 is installed at one end of drill rod 3 and is used to clean up slag.

[0045] The drill rod 3 is capable of rotating and moving axially along the instrument connector 7. The drill rod 3 is directly and movably connected to the connection hole 11 at the center of the flange, or indirectly and movably connected to the connection hole 11 at the center of the flange through a driving component; that is, the drill rod 3 moves through the connection hole 11 at the center of the flange, or one end of the drill rod 3 is connected to a driving component, which moves through the connection hole 11 at the center of the flange, causing the drill rod 3 to rotate and move axially along the instrument connector 7.

[0046] The slag discharge spiral 4 is installed on the drill rod 3. The drill rod 3, drill bit 2 and slag discharge spiral 4 can enter and exit the instrument pipe 7. The slag discharge spiral 4 is used to transport the slag cleaned by the drill bit 2 to the slag discharge port 12.

[0047] The sealing structure serves a sealing function; when the drill rod 3 moves through the connecting hole 11 in the center of the flange, the sealing structure is used to achieve a dynamic seal between the drill rod 3 and the connecting hole 11; when the drill rod 3 moves through the connecting hole 11 in the center of the flange through the driving component, the sealing structure is used to achieve a dynamic seal between the driving component and the connecting hole 11.

[0048] In use, first close the root valve of the instrument connector 7 (not shown in the figure), connect the connector 1 to the instrument connector 7, and close the slag discharge valve 13 to ensure that the space between the root valve and the connector 1 is completely sealed (preventing slag splashing). Then, manually or by motor drive the drill rod 3 to move the drill bit 2 and the slag discharge screw 4. Both can break up the slag accumulated in the instrument connector 7. Then, reverse the drill rod 3, and the slag will enter the slag discharge port 12 under the rotating conveying action of the slag discharge screw 4. Open the slag discharge valve 13 to discharge the slag. After slag discharge, close the slag discharge valve 13, disassemble and reassemble the instrument maintenance tool, and reinstall the thermometer, pressure gauge, and other instruments. By using the above method, the interference of slag blockage in the instrument connector 7 is eliminated, and the accuracy of instrument detection is restored. The use of the instrument maintenance tool is convenient and safer.

[0049] like Figure 1 As shown, in this embodiment, a design is selected where "one end of the drill rod 3 is connected to a driving component, and the driving component movably passes through the connecting hole 11 at the center of the flange". The driving component includes a lead screw 61, one end of which is connected to the drill rod 3, and the lead screw 61 movably passes through the connecting hole 11; the lead screw 61 is threadedly connected to a support assembly, and the support assembly is installed on the connector 1. When the lead screw 61 is rotated, the support assembly remains stationary, and the drill rod 3, drill bit 2, and slag discharge auger 4 are driven to move through the lead screw 61.

[0050] The support assembly includes a positioning rod 62, a support plate 63, a guide block 64, and a pressure plate 65; one end of the positioning rod 62 is connected to the connector 1 and the other end is connected to the support plate 63; the guide block 64 is threadedly connected to the lead screw 61; the pressure plate 65 fastens the guide block 64 to the support plate 63 with bolts.

[0051] In this embodiment, the lead screw 61 is driven manually. To facilitate manual operation of the lead screw 61, a handwheel 66 is installed on the lead screw 61 for easy gripping by the operator.

[0052] The sealing structure includes a sealing packing 51 and a packing gland 52; the packing gland 52 is sleeved on the drive component, and the packing gland 52 is detachably connected to the side of the connector 1 away from the drill bit 2 by bolts. The sealing packing 51 is disposed between the packing gland 52 and the connecting hole 11. The sealing packing 51 is graphite packing.

[0053] In this embodiment, after connecting the connector 1 to the instrument pipe 7, the maximum lateral distance between the axis of the instrument pipe 7 and the slag discharge port 12 is less than or equal to 1 / 2 of the inner diameter of the instrument pipe 7. In this way, the slag discharge port 12 is not easily partially blocked by the instrument pipe 7, which helps to ensure smooth slag discharge.

[0054] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
