Description

Technical Field

[0001] This application relates to the field of graphite boat cleaning technology, specifically to a support assembly for an automatic graphite boat cleaning machine. Background Technology

[0002] In the manufacturing process of solar photovoltaic cells, the PE (polyethylene precipitate) process is a core step. It requires a graphite boat as a carrier to place the solar cells, where passivation films are deposited on both sides in a high-temperature furnace. However, with repeated use, a passivation film forms on the surface of the graphite boat, affecting its conductivity and the coating effect on the solar cells. Therefore, regular cleaning of the graphite boat is necessary to remove the passivation film. Furthermore, with the increasing global emphasis on renewable energy and the continuous expansion of the solar photovoltaic industry, higher demands are placed on the cleaning efficiency and quality of graphite boats. Traditional manual cleaning methods can no longer meet the needs of large-scale production, thus driving the development of automated graphite boat cleaning technology and its supporting support systems.

[0003] When cleaning graphite boats using existing cleaning machines, the entire internal space of the machine is cleaned at once. It is not possible to clean individual sections of the machine based on the number of graphite boats. As a result, even when the machine is not full of graphite boats, the entire machine needs to be started to clean them, which wastes water resources and increases costs.

[0004] Therefore, it is necessary to provide a bracket assembly for an automatic cleaning machine for graphite boats to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a support assembly for an automatic cleaning machine for graphite boats, so as to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is: a support assembly for an automatic cleaning machine for graphite boats, including a frame installed in the automatic cleaning machine, a longitudinal tube fixed in the frame, and a water inlet opened at the end of the longitudinal tube near the frame.

[0007] The frame is divided into several cleaning zones. Each cleaning zone has a horizontal pipe that intersects with the longitudinal pipe on both sides. The horizontal pipe and the longitudinal pipe are connected. Each horizontal pipe is equipped with a spray assembly. A control valve is provided on the horizontal pipe at the position between the spray assembly and the longitudinal pipe.

[0008] The top of the control valve is provided with a support unit supported by a spring. When the graphite boat is placed on the support unit, the graphite boat causes the support unit to overcome the spring force and move down by its own weight to open the control valve, so that the liquid flowing from the longitudinal pipe into the transverse pipe can reach the spray assembly through the control valve and be sprayed outward.

[0009] When the graphite boat detaches from the support unit, the spring releases its elastic force and moves upward to close the control valve.

[0010] Furthermore, the control valve has an inlet chamber on one side and an outlet chamber communicating with the inlet chamber on the other side. The horizontal pipe includes an inlet pipe section and an outlet pipe section located on both sides of the control valve. One end of the inlet pipe section is connected to the vertical pipe, and the other end is connected to the inlet chamber. The outlet chamber is connected to the outlet pipe section. The spray assembly is located in the outlet pipe section.

[0011] Furthermore, the supporting unit includes a column fixedly connected to the top of the control valve, and a sliding cavity is provided at the top of the column, with a sliding column slidably connected inside the sliding cavity.

[0012] A valve stem is slidably connected inside the column, the spring is located inside the sliding cavity, the top end of the valve stem has a limiting part, one end of the spring abuts against the limiting part, and the other end abuts against the bottom wall of the sliding cavity, and the top end of the limiting part is fixedly connected to the bottom end of the sliding column;

[0013] The control valve has a connecting hole located between the inlet chamber and the outlet chamber. A sealing gasket for opening or closing the connecting hole is fixedly connected to the bottom of the valve stem. The sealing gasket is located below the connecting hole.

[0014] Furthermore, the top of the sliding column is rotatably connected to an upper placement frame and a lower placement frame.

[0015] Furthermore, both the upper and lower placement racks have anti-slip layers on their top surfaces, and these layers are at the same height.

[0016] Furthermore, the automatic cleaning machine has a cleaning chamber inside and an installation part on the inner wall. The frame is installed on the installation part, and the bottom of the cleaning chamber is connected to a discharge port.

[0017] The beneficial effects of this application are as follows: The bracket assembly for an automatic graphite boat cleaning machine provided by this application, by providing a bearing unit, can support and fix the graphite boat. After the graphite boat is installed, its own weight can press down the valve rod, which connects the control valve in the cleaning area where the graphite boat is installed, thereby allowing water to pass through and spray out from the spray assembly to clean the graphite boat. Conversely, the cleaning area without the graphite boat is resisted by the sealing gasket, and the spray assembly does not produce water, thus saving water resources and reducing costs.

[0018] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1-6As shown, this application provides a technical solution: a bracket assembly for an automatic cleaning machine for graphite boats, including a frame 2 installed in the automatic cleaning machine 1, a longitudinal tube 201 fixed inside the frame 2, and a water inlet 23 opened at the end of the longitudinal tube 201 near the frame 2.

[0032] The frame 2 is divided into several cleaning zones 21. Each cleaning zone 21 has a horizontal pipe 202 that is intersected with the longitudinal pipe 201 on both sides. The horizontal pipe 202 is connected to the longitudinal pipe 201. Each horizontal pipe 202 is equipped with a spray assembly 22. A control valve 3 is provided on the horizontal pipe 202 at the part between the spray assembly 22 and the longitudinal pipe 201.

[0033] The top of the control valve 3 is provided with a support unit supported by a spring 9. When the graphite boat is placed on the support unit, the graphite boat causes the support unit to overcome the elastic force of the spring 9 and move down to open the control valve 3, so that the liquid flowing from the longitudinal pipe 201 into the transverse pipe 202 can reach the spray assembly 22 through the control valve 3 and be sprayed outward.

[0034] When the graphite boat detaches from the support unit, spring 9 releases its elastic force and moves upward to close control valve 3.

[0035] Both horizontal pipe 202 and vertical pipe 201 are steel pipes.

[0036] The control valve 3 has an inlet chamber 32 on one side and an outlet chamber 33 connected to the inlet chamber 32 on the other side. The horizontal pipe 202 includes an inlet pipe section 2021 and an outlet pipe section 2022 located on both sides of the control valve 3. One end of the inlet pipe section 2021 is connected to the vertical pipe 201 and the other end is connected to the inlet chamber 32. The outlet chamber 33 is connected to the outlet pipe section 2022. The spray assembly 22 is located in the outlet pipe section 2022.

[0037] The supporting unit includes a column 4 fixedly connected to the top of the control valve 3. The top of the column 4 has a downward sliding cavity 41, and a sliding column 10 is slidably connected inside the sliding cavity 41.

[0038] A valve stem 7 is slidably connected inside the column 4. A spring 9 is located inside the sliding cavity 41. The top end of the valve stem 7 has a limiting part 71. One end of the spring 9 abuts against the limiting part 71, and the other end abuts against the bottom wall of the sliding cavity 41. The top end of the limiting part 71 is fixedly connected to the bottom end of the sliding column 10.

[0039] The control valve 3 has a connecting hole 31 located between the water inlet chamber 32 and the water outlet chamber 33. The bottom of the valve stem 7 is fixedly connected to a sealing gasket 8 for opening or closing the connecting hole 31. The sealing gasket 8 is located below the connecting hole 31.

[0040] The top of the sliding column 10 is rotatably connected to the upper placement frame 5 and the lower placement frame 6.

[0041] The top surfaces of both the upper shelf 5 and the lower shelf 6 are equipped with anti-slip layers and are at the same height.

[0042] The automatic cleaning machine 1 has a cleaning chamber 11 inside and an installation part 12 on the inner wall. The frame 2 is installed on the installation part 12, and the bottom of the cleaning chamber 11 is connected to the discharge port 13.

[0043] In one embodiment, the support operates on the following principle.

[0044] Specifically, the frame 2 is installed on the mounting part 12. The corresponding cleaning area 21 is selected according to the number of graphite boats to be cleaned. According to the size of the graphite boat, the upper placement frame 5 and the lower placement frame 6 on the two control valves 3 are rotated to unfold them. The graphite boat is inverted on the upper placement frame 5 and the lower placement frame 6 to support the graphite boat. The anti-slip layer can increase the friction and prevent tilting.

[0045] After the upper placement frame 5 and the lower placement frame 6 are subjected to pressure, the sliding column 10 is driven to move downward. The sliding column 10 presses down the valve rod 7 to disengage the sealing gasket 8 from the water outlet chamber 33, thereby controlling the valve 3 to connect. In the same way, the graphite boats that need to be cleaned are placed upside down on the corresponding cleaning area 21.

[0046] At this time, the water source is connected to the inlet 23, and water flows from the longitudinal pipe 201 into the horizontal pipe 202. The water flows through the inlet pipe section 2021, the inlet chamber 32, the connecting hole 31, the outlet chamber 33 and the outlet pipe section 2022 in sequence, and then sprays out from the spray assembly 22. The two spray assemblies 22 clean the inner cavity of the graphite boat, and the automatic cleaning machine 1 cleans the outer periphery of the graphite boat.

[0047] In the cleaning area 21 where the graphite boat is not installed, the sealing gasket 8 still abuts against the bottom of the connecting hole 31, and no water is discharged from the spray assembly 22, saving water resources.

[0048] When the cleaned graphite boat is removed from the support unit, the spring 9 releases its elastic force and moves upward, and the sealing gasket 8 abuts against the bottom of the connecting hole 31 to close the control valve 3.

[0049] In summary, this device, by incorporating a support unit, can support and fix the graphite boat. After the graphite boat is installed, its own weight presses down on the valve stem 7, connecting the control valve 3 in the cleaning zone 21 where the graphite boat is installed. This allows water to flow through and be sprayed from the spray assembly 22 to clean the graphite boat. Conversely, the cleaning zone 21 without a graphite boat is held back by the sealing gasket 8, preventing water from flowing from the spray assembly 22, thus saving water resources and reducing costs. This solves the technical problem of existing cleaning machines that, when cleaning graphite boats, require starting the entire machine to clean the entire internal space, rather than cleaning individual sections based on the number of graphite boats. This results in the entire cleaning machine needing to be started even when the machine is not full, leading to water waste and increased costs.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. 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.
