Description

Technical Field

[0001] The utility model belongs to the technical field of waste discharge components, and particularly relates to a waste discharge component for solar cell production. Background Art

[0002] In the production process of solar cells, metaphosphoric acid is generated after the process of the diffusion furnace machine is completed. Due to the gas circulation in the diffusion furnace process, the metaphosphoric acid can be discharged in time. Therefore, the metaphosphoric acid is mainly generated after the diffusion furnace process is completed, and then the metaphosphoric acid is discharged through a waste discharge pipe. When the waste discharge pipe discharges the metaphosphoric acid, part of the metaphosphoric acid remains in the waste discharge pipe. After a long time, it condenses in the waste discharge pipe, resulting in the adhesion of the waste discharge pipe to the furnace body, greatly increasing the friction force between the waste discharge pipe and the furnace body, and making it inconvenient to pull out the waste discharge pipe during maintenance. Moreover, the waste discharge pipe is generally a quartz pipe with low hardness. If the force is not applied properly during the pulling-out process, the quartz pipe is likely to break, thus increasing the maintenance cost.

[0003] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0034] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0035] As Figures 1 to 8 shown, a waste discharge component for solar cell production in an embodiment of the present utility model includes a waste discharge pipe, which is installed on the waste gas discharge pipeline of the furnace body, and the two are connected by plugging. The waste gas discharged from the furnace body contains metaphosphoric acid, and metaphosphoric acid will adhere between the waste discharge pipe and the waste gas discharge pipe of the furnace body during the discharge process, increasing the difficulty of pulling out the waste discharge pipe from the waste gas discharge pipe of the furnace body.

[0036] As Figures 1 to 8 shown, the waste discharge component further includes a first ejection structure 1 and a second ejection structure 3 for disassembling the waste discharge pipe. The first ejection structure 1 is a hollow structure, and the waste discharge pipe is located inside the first ejection structure 1. The second ejection structure 3 is threadedly connected to the first ejection structure 1. During use, the second ejection structure 3 is rotationally connected to the first ejection structure 1, so that the second ejection structure 3 moves away from one end of the first ejection structure 1. The second ejection structure 3 applies a force to the waste discharge pipe in the direction away from the furnace body, forcing the waste discharge pipe to lose connection with the waste gas discharge pipe of the furnace body, thereby disassembling the waste discharge pipe from the waste gas discharge pipe of the furnace body.

[0037] Specifically, as Figures 1 to 5 shown, the first ejection structure 1 includes two first arc-shaped blocks 11. The two first arc-shaped blocks 11 form an annular structure matching the waste discharge pipe. The first arc-shaped block 11 has a first contact surface 111 and a second contact surface 112. A rotating structure is provided at one end of the first arc-shaped block 11 close to the first contact surface 111. The rotating structure can be a hinge connection, a hinge joint or other rotating connection methods. A locking structure is provided at one end of the first arc-shaped block 11 close to the second contact surface 112. The two first contact surfaces 111 are rotatably connected through the rotating structure. The locking structure can be specifically divided into a clamping lock and other locking structures. In this embodiment, the locking of the two first arc-shaped blocks 11 is realized by means of magnetic attraction connection. That is, the locking structure includes two magnetic attraction blocks 13. The two magnetic attraction blocks 13 are respectively installed on one side wall of the first ejection structure 1 close to the second contact surface 112, and the two magnetic attraction blocks 13 attract each other to realize magnetic attraction connection.

[0038] As Figures 1 to 5 shown, the second ejection structure 3 includes two third arc-shaped blocks 31. The two third arc-shaped blocks 31 are rotatably connected. The two third arc-shaped blocks 31 are rotatably connected to form a ring matching the first ejection structure 1. A second arc-shaped block 12 is fixedly connected to the first arc-shaped block 11. An external thread 121 is provided on the outer wall of the second arc-shaped block 12. That is, the two third arc-shaped blocks 31 form a ring matching the second arc-shaped block 12. An internal thread 311 matching the external thread 121 is provided on the inner wall of the third arc-shaped block 31. The internal thread 311 and the external thread 121 are in threaded connection. That is, the second ejection structure 3 can be sleeved on the first ejection structure 1 and is in threaded connection with the first ejection structure 1.

[0039] Specifically, as Figures 1 to 5 shown, a second connecting member 32 is fixedly connected to one end of the third arc-shaped block 31. A rotating shaft 33 is installed between the two second connecting members 32. That is, the two third arc-shaped blocks 31 are rotatably connected through the second connecting member 32 and the rotating shaft 33. The second connecting member 32 and the rotating shaft 33 protrude from the outer wall of the third arc-shaped block 31 to form a handle. When it is necessary to rotate the third arc-shaped block 31, the handle can be held by hand, which is convenient for the second ejection structure 3 to rotate on the first ejection structure 1.

[0040] As Figures 1 to 5As shown, one end of a third arc-shaped block 31 away from the second connecting member 32 is fixedly connected with a first connecting ear 312, and a connecting column 313 is fixedly connected to the first connecting ear 312. The other end of the third arc-shaped block 31 away from the second connecting member 32 is fixedly connected with a second connecting ear 314, and a through hole 3141 matching the connecting column 313 is formed in the second connecting ear 314. The connecting column 313 can pass through the through hole 3141, and the connecting column 313 is then threadedly connected with a nut to realize the locking of the two third arc-shaped blocks 31, ensuring that the third arc-shaped block 31 is not easily separated from the first ejecting structure 1 during the rotation process.

[0041] Generally, the thread depths of the internal thread 311 and the external thread 121 are greater than 0.5 cm. The threaded fit with a deep thread depth is adopted to avoid the phenomenon of thread slipping during the rotation of the first ejecting structure 1 and the second ejecting structure 3, which affects the normal use of the waste discharging assembly.

[0042] During use, first open the first arc-shaped block 11, then sleeved the first arc-shaped block 11 between the waste discharging pipe and the furnace body, and then open the third arc-shaped block 31, sleeved it on the first ejecting structure 1 and lock it through the connecting column 313 and the second connecting ear 314, so that the internal thread 311 and the external thread 121 are in threaded fit. Try to ensure that the central axis of the first ejecting structure 1 and the central axis of the waste discharging pipe are on the same straight line, rotate the second ejecting structure 3 to increase the distance between the first ejecting structure 1 and the second ejecting structure 3. The second ejecting structure 3 applies a force to the waste discharging pipe to move it away from the furnace body, forcing the waste discharging pipe to separate from the furnace body. During the separation process of the waste discharging pipe, the force applied by the second ejecting structure 3 to the contact surface between the waste discharging pipe and the second ejecting structure 3 is relatively uniform, as much as possible to avoid the situation that the waste discharging pipe breaks or is damaged due to uneven force applied during the process of disassembling the second ejecting structure 3.

[0043] Preferably, rubber is provided on the contact surface between the second ejecting structure 3 and the waste discharging pipe to reduce the possibility of damage to the waste discharging pipe caused by the second ejecting structure 3.

[0044] As Figures 1 to 3 shown, the outer diameter of the second arc-shaped block 12 is smaller than the outer diameter of the first ejecting structure 1, and the inner diameter of the second arc-shaped block 12 is equal to or greater than the outer diameter of the waste discharging pipe.

[0045] To solve the problem that the first ejection structure 1 and the second ejection structure 3 may hit the waste discharge pipe during rotation due to improper operation, a connecting structure 2 is installed at one end of the first ejection structure 1 away from the second ejection structure 3. The connecting structure 2 can fixedly connect the first ejection structure 1 to the furnace body, so that during the rotation of the second ejection structure 3 and the first ejection structure 1, the first ejection structure 1 will not move randomly, causing damage to the waste discharge pipe, and at the same time, it can also reduce the operation of the first ejection structure 1 and the second ejection structure 3 for disassembling the waste discharge pipe. When the first ejection structure 1 and the second ejection structure 3 are not used for disassembly, the first ejection structure 1 and the connecting structure 2 cooperate. In the initial state, the first ejection structure 1 and the connecting structure 2 can lift the waste discharge pipe, as much as possible to avoid the deformation of the waste discharge pipe caused by the long-term downward force on the waste discharge pipe.

[0046] Specifically, the connecting structure 2 includes a connecting rod 21 and a first connecting piece 22. The connecting rod 21 is a telescopic rod. The first connecting piece 22 can be bolted to the furnace body, or the first ejection structure 1 can be installed on the furnace body by other connection methods such as magnetic attraction and clamping. In this embodiment, the first connecting piece 22 is a suction cup. The inner diameter of the second arc-shaped block 12 is equal to the outer diameter of the waste discharge pipe. The first ejection structure 1 is sleeved on the waste discharge pipe, and then the first ejection structure 1 is fixed to the furnace body through the connecting structure 2 to ensure that the central axis of the first ejection structure 1 and the central axis of the waste discharge pipe are on the same straight line. At this time, when the second ejection structure 3 rotates on the first ejection structure 1, the force applied to the waste discharge pipe is relatively uniform, largely avoiding the situation of the waste discharge pipe breaking or cracking during the use of the first ejection structure 1 and the second ejection structure 3.

[0047] As Figures 9 to 10 shown, a ring 4 is rotatably connected to one end of the third arc-shaped block 31 away from the first ejection structure 1. An annular groove 315 is opened at one end of the third arc-shaped block 31 away from the first ejection structure 1. A ring protrusion 41 matching the annular groove 315 is fixedly connected to the ring 4. The ring protrusion 41 and the second ejection structure 3 are rotatably connected. When the second ejection structure 3 rotates on the first ejection structure 1, the ring 4 can remain stationary. During the rotation of the second ejection structure 3, the ring 4 can still apply a force to separate the waste discharge pipe from the furnace body, and the ring 4 does not rotate, so it is not easy to cause wear to the waste discharge pipe.

[0048] Preferably, the ring 4 is an annular ring with an opening. The ring 4 has elasticity and can be detached from the second ejection structure 3 through the opening, and can also be installed on the second ejection structure 3 through the opening. Rubber is provided on the contact surface of the ring 4 with the waste discharge pipe to reduce the wear of the ring 4 on the waste discharge pipe.

[0049] During installation, firstly, sleeve the first arc block 11 onto the outer wall of the waste pipe, make the inner wall of the second arc block 12 contact the outer wall of the waste pipe, and lock the two first arc blocks 11 by the magnetic block 13. Then slide on the waste pipe, slide the first ejection structure 1 to the position where the connecting structure 2 can be fixedly connected to the furnace body and can apply disassembly force to the waste pipe. Fix the connecting structure 2 to the furnace body to complete the fixed installation of the first ejection structure 1. Then sleeve the third arc block 31 onto the two second arc blocks 12, make the internal thread 311 cooperate with the external thread 121, and lock them by the connecting column 313 and the second connecting ear 314, so as to avoid the situation where the two second ejection structures 3 are separated from the second arc block 12 during the rotation of the second ejection structure 3 as much as possible.

[0050] When in use, the second ejection structure 3 is rotated on the first ejection structure 1, and the second ejection structure 3 moves with the annular ring 4 to the end away from the furnace body. The annular ring 4 contacts one end surface of the waste discharge pipe and brings the force generated by the second ejection structure 3 to the annular ring 4. The annular ring 4 is evenly transmitted to the waste discharge pipe, so that the waste discharge pipe can receive uniform force during the pulling out process, and the situation that the service life of the waste discharge pipe is affected by the uneven pulling out force of the waste discharge pipe is avoided as much as possible.
