[0002] In the process of cleaning photovoltaic cells, in order to make the chemicals in the tank more evenly mixed, the tank structure is designed with a main tank and a secondary tank. A circulation pipe and a circulation pump are set between the main tank and the secondary tank. The chemical solution is pumped from the secondary tank into the circulation pipe through the circulation pump, and then injected into the main tank through the circulation pipe. After the main tank is full of chemical solution, it flows back to the secondary tank, forming a circulation process.

[0003] The circulation pipe inside the main tank has multiple small outlet holes, through which liquid is sprayed to different locations within the main tank. Depending on the type of product or process, the orientation of the outlet holes in the circulation pipe within the main tank may need to be adjusted, or a different type of circulation pipe may need to be used.

[0004] However, the existing circulation pipes are fixed with fasteners, and the discharge direction of the liquid outlet holes of the circulation pipes is not easy to adjust. Moreover, during the installation or disassembly of the circulation pipes, operators need to enter the main tank to install or disassemble them. There will be chemical residues in the main tank, which can easily cause harm to the operators. Utility Model Content

[0026] Reference Figures 1 to 5 This utility model provides an example of a circulation pipe structure that is easy to adjust and disassemble, including a first pipe body 100, a second pipe body 110, and a union assembly 120. The first pipe body 100 is connected to a tank 130, and the second pipe body 110 is connected to the output end of a circulation pump 140. The first pipe body 100 and the second pipe body 110 are connected by the union assembly 120. The outer periphery of the first pipe body 100 is provided with a plurality of small liquid outlet holes 150. A through hole is provided on one side of the tank 130. The inner wall of the through hole is connected to a first flange 160. The center of the first flange 160 is provided with an inner hole through which the first pipe body 100 passes. The outer periphery of the first flange 160 is provided with an external thread. The outer periphery of the first pipe body 100 is provided with a first flange 170. The first flange 160 and the first flange 170 are connected by a first retaining nut 180.

[0027] Specifically, one end of the first ferrule nut 180 is provided with a first inner boss 190, which is used to engage one side of the first flange 170. The first inner boss 190 engages with one side of the first flange 170.

[0028] During installation, first fix the first flange 160 onto the through hole of the tank 130, with the threaded side of the first flange 160 facing outwards from the tank 130. Next, pass the first tube 100 through the inner hole of the first flange 160 and push the first tube 100 until one side of the first flange 170 on the first tube 100 abuts against one side of the first flange 160. At the same time, the multiple liquid outlet holes 150 on the outer periphery of the first tube 100 are all located inside the tank 130. By rotating the first tube 100, the multiple liquid outlet holes 150 are aligned appropriately with the inside of the tank 130. The first inner boss 190 on the first ferrule nut 180 engages with the side of the first flange 170 away from the first flange 160. By turning the first ferrule nut 180, the external thread of the first ferrule nut 180 is screwed into the external thread of the first flange 160. During the tightening of the first ferrule nut 180, the first inner boss 190 of the first ferrule nut 180 will continuously press the first flange 170 against the side of the first flange 160. Finally, the first end of the first tube body 100 is connected to the second end of the second tube body 110 through the union assembly 120.

[0029] When it is necessary to adjust the discharge direction of the multiple outlet holes 150 on the outer periphery of the first tube body 100, simply loosen the first ferrule nut 180 and the union assembly 120, then rotate the first tube body 100 so that the multiple outlet holes 150 on the outer periphery of the first tube body 100 face the desired position, and finally tighten the first ferrule nut 180 and the union assembly 120. Thus, adjustment or disassembly can be achieved without the operator entering the tank body 130, avoiding harm to the operator from residual chemicals in the tank body 130, and improving convenience and safety.

[0030] In some preferred embodiments, a first sealing ring 200 is provided between the first flange 160 and the first flange 170.

[0031] Understandably, when the first ferrule nut 180 is tightened, the first flange 170 approaches the first flange 160. At the same time, the first flange 170 presses the first sealing ring 200 against one side of the first flange 160, causing the first sealing ring 200 to undergo elastic deformation. The radial expansion of the first sealing ring 200 can fill the gap between the first flange 170 and the first flange 160, thereby preventing liquid leakage in the tank 130 and greatly improving the sealing performance.

[0032] Furthermore, a first sealing groove 210 for accommodating the first sealing ring 200 is provided on one side of the first flange 160 or the first flange 170. The first sealing groove 210 can position the first sealing ring 200 to prevent it from loosening or falling off during installation. At the same time, the first sealing groove 210 provides a uniform compression space to ensure that the circumferential deformation of the first sealing ring 200 is consistent, avoiding over-compression or under-compression of the first sealing ring 200, and ensuring that the first sealing ring 200 fits tightly against the sides of the first flange 160 and the first flange 170.

[0033] Furthermore, the first flange 160 is welded to the tank 130, and the first flange 170 is welded to the outer periphery of the first tube 100, which can improve the stability and sealing of the first flange 160 and the first flange 170.

[0034] In some preferred embodiments, the live joint assembly 120 includes a second flange 220 and a second ferrule nut 230. The second flange 220 is disposed on one side of the first tube body 100 and has an external thread on its outer periphery. One end of the first tube body 100 is provided with a second flange 240. The second flange 220 and the second flange 240 are connected by the second ferrule nut 230.

[0035] Specifically, one end of the second ferrule nut 230 is provided with a second inner boss 250, which engages with one side of the second flange 240.

[0036] During installation, one side of the second flange 220 abuts against one side of the second flange 240. The second inner boss 250 on the second ferrule nut 230 engages the second flange 240 on the side away from the second flange 220. By tightening the second ferrule nut 230, the second ferrule nut 230 engages with the external thread of the second flange 220. During the tightening process, the second inner boss 250 of the second ferrule nut 230 continuously presses the second flange 240 against one side of the second flange 220, thereby facilitating the connection and disassembly between the first tube body 100 and the second tube body 110.

[0037] In some preferred embodiments, a second sealing ring 260 is provided between the second flange 220 and the second flange 240.

[0038] Understandably, when the second ferrule nut 230 is tightened, the second flange 240 presses the second sealing ring 260 against one side of the second flange 220, causing the second sealing ring 260 to undergo elastic deformation. The radial expansion of the second sealing ring 260 can fill the gap between the second flange 240 and the second flange 220, thereby preventing liquid from leaking between the first tube 100 and the second tube 110 and greatly improving the sealing performance between the first tube 100 and the second tube 110.

[0039] Furthermore, a second sealing groove 270 for accommodating the second sealing ring 260 is provided on one side of the second flange 220 or the second flange 240. The second sealing groove 270 can position the second sealing ring 260 to prevent it from loosening or falling off during installation. At the same time, the second sealing groove 270 provides a uniform compression space, ensuring that the circumferential deformation of the second sealing ring 260 is consistent, avoiding over-compression or under-compression of the second sealing ring 260, and ensuring that the second sealing ring 260 fits tightly against the sides of the second flange 220 and the second flange 240.

[0040] In some preferred embodiments, one end of the second tube 110 is formed into a second flange 240 by a flange, so that the second flange 240 and the second tube 110 are integrally formed without welds, thereby improving the structural strength and sealing performance of the second flange 240 and the second tube 110.

[0041] Furthermore, the second mandrel 220 is welded to one end of the first tube 100, which can improve the stability and sealing of the connection between the second mandrel 220 and the first tube 100.

[0042] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
