[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0034] See also Figure 1-Figure 8 , Fig.11 The cooling water tower filter of this embodiment includes an outer tube 110, a filter tube 310, and a clamp assembly 200. The two ends of the outer tube 110 are respectively provided with outer tube flanges 120 and the interior of the outer tube 110 is a hollow outer tube cavity 111; the two ends of the outer tube 110 are respectively assembled with different connecting tubes 130 through different clamp assemblies 200, and the connecting tubes 130 are respectively provided with connecting tube flanges 131 and connecting tube rings 132. A sealing gasket 410 is clamped between the connecting tube flange 131 and the corresponding outer tube flange 120, and the connecting tube flange 131 and the outer tube flange 120 are sealed by clamping the sealing gasket 410.

[0035] The connecting pipe 130 is provided with a connecting nut 140, and the connecting nut 140 cannot pass through the connecting pipe ring 132. When in use, the connecting nut 140 is screwed and assembled with the external thread of the corresponding pipe to realize the installation and connection of the entire cooling water tower filter and the pipeline. This is the prior art, which is actually a sealing ring clamped between two similar connecting pipe rings 132 to achieve sealing, and the connecting nut 140 is screwed with the external thread to achieve connection. Such as the connection structure of the water pipe of the water heater and the connection structure of the water inlet pipe of the toilet in the prior art.

[0036] The clamp assembly 200 includes a first clamp member 210 and a second clamp member 220, one end of the first clamp member 210 and the second clamp member 220 are respectively hinged to the clamp connector 230, and the inner sides of the first clamp member 210 and the second clamp member 220 are also provided with clamp grooves 201, and the side walls of the clamp grooves 201 are clamp slopes 202; a notch 221 is provided on the end of the second clamp member 220 away from the clamp connector 230, and the end of the first clamp member 210 away from the clamp connector 230 is hinged to one end of a clamp screw 240, and a nut 250 is mounted on the clamp screw 240, and the nut 250 is screwed together with the clamp screw 240 through a thread. When in use, the clamp screw 240 is inserted into the notch 221 , and then the nut 250 is tightened, and the nut 250 is pressed against the second clamp member 220 to achieve the compression assembly of the first clamp member 210 and the second clamp member 220 .

[0037] See also Fig.11 The outer tube flange 120, the connecting tube flange 131 and the clamp bevel 202 are respectively provided with an outer tube bevel 121 and a connecting bevel 1311 at corresponding positions thereof. The clamp bevel 202 is respectively pressed against the outer tube bevel 121 and the connecting bevel 1311 to press the outer tube flange 120 and the connecting tube flange 131 against each other axially to realize the assembly of the connecting tube 130 and the outer tube 110, and at the same time squeeze the sealing gasket 410 to realize sealing.

[0038] See also Figure 1-Figure 8 The filter tube 310 has a hollow filter tube cavity 311 inside, with both ends of the filter tube cavity 311 opened and one end closed by a filter end cap 320, and the filter end cap 320 is installed on the filter tube 310; the end of the filter tube 310 away from the filter end cap 320 is installed in the corresponding connecting tube 130 and cannot be axially moved relative to the connecting tube 130;

[0039] The side wall of the filter tube 310 is provided with a plurality of through filter holes 312 , and the filter end cover 320 is provided with a plurality of through holes , and both the filter holes and the through holes are used to filter large particles of impurities in water.

[0040] The filter tube 310 is installed in the outer tube cavity 111 and the sealing gasket 410 is pressed between the connecting tube flange 131 of the connecting tube 130 installed on the filter tube 310 and the corresponding outer tube flange 120, so that the outer wall of the filter tube 310 does not contact the inner wall of the outer tube cavity 111. Then open the clamp assembly 200 to Figure 6In this state, the clamp grooves 201 of the first clamp member 210 and the second clamp member 220 are respectively mounted on the corresponding connecting pipe flange 131 and the outer pipe flange 120, the clamp screw 240 is rotated to fit into the notch 221, and the nut 250 is tightened so that the first clamp member 210 and the second clamp member 220 clamp the corresponding connecting pipe flange 131 and the outer pipe flange 120. The connection method of the connecting pipe 130 at the other end and the corresponding outer pipe flange 120 is the same.

[0041] When in use, first connect the corresponding connecting pipe 130 to the pipeline through the connecting nut 140 at one end, then install the filter tube 310 into the outer tube 110 and fix the filter tube 310 and the outer tube 110 through the clamp assembly 200, then connect the corresponding connecting pipe 130 to the pipeline through the connecting nut 140 at the other end, and then assemble and fix the connecting pipe 130 that is not matched with the filter tube 310 with the corresponding outer tube flange 120 through another clamp assembly 200, thereby completing the installation of the entire cooling water tower filter.

[0042] by Figure 3 When the filter tube 310 needs to be cleaned, open the left clamp assembly 200, then loosen the connecting nut 140 on the right, and remove the cooling water tower filter as a whole. Then open the other clamp assembly 200, pull the filter tube 310 out of the outer tube 110, so that the outer tube cavity 111 and the filter tube 310 can be cleaned. After cleaning, assemble the cooling water tower filter and install the cooling water tower filter back into the pipeline. There is no bolt disassembly in the whole process, and the disassembly and assembly method of the clamp assembly can greatly improve the disassembly and assembly efficiency on the one hand, and ensure the sealing of the connection on the other hand. Example

[0043] See also Figure 9-Figure 16 Although the disassembly and assembly efficiency can be improved in the first embodiment, there is no support in the circumferential direction of the filter tube 310 after it is installed in the outer tube cavity 111, which affects the subsequent clamp assembly clamping installation, because once the connecting pipe flange 131 and the outer tube flange 120 are not aligned and tightly attached, it will affect the clamp assembly clamping installation, and it is easy to make the connecting pipe flange 131 and the outer tube flange 120 not aligned when the filter tube 310 is not supported in the circumferential direction. For this reason, in this embodiment, a pipe sleeve 330 is installed outside the filter tube 310, and the outer wall of the pipe sleeve 330 is attached to the inner wall of the outer tube cavity 111 to provide support for the filter tube 310, so as to greatly facilitate the installation of the clamp assembly. At the same time, a pipe sleeve through groove 331 is provided on the pipe sleeve 330, and the pipe sleeve through groove 331 is used to connect the outer tube cavities 111 on both sides of the pipe sleeve 330.

[0044] In addition, the filter end cap 320 and the filter tube 310 in the first embodiment are of a non-detachable design. This method makes the process of cleaning the filter tube cavity 311 very unchanged. The main problem is that when backwashing or brushing the filter tube 310, the blocking of the filter end cap 320 will affect the cleaning of the filter tube 310 near the filter end cap 320 and the inner side of the filter end cap 320. In this regard, the filter end cap 320 is designed to be detachable from the filter tube 310 in this embodiment, as follows:

[0045] A retaining ring 340 is installed on the end of the filter tube 310 away from the corresponding connecting tube 130. The retaining ring 340 is assembled and fixed with the filter tube 310 through a connecting portion 342, and a plug-in groove 341 is formed between the retaining ring 340 and the end of the filter tube 310. The filter end cover 320 is inserted into the plug-in groove 341 to complete the assembly with the filter tube 310.

[0046] In some embodiments, a protrusion 321 is provided on the filter end cap 320, and the protrusion 321 protrudes from the end surface of the filter end cap 320 in the axial direction of the filter end cap 320. This design is mainly to facilitate the filter end cap 320 to be pulled out from the plug-in slot 341. When in use, the filter end cap 320 can be easily pulled out by holding the protrusion 321 with fingers.

[0047] The retaining ring 340 is provided with a retaining ring groove 343 into which the protrusion 321 can be inserted. The retaining ring 340 is provided with elastic sheets 350 on both sides of the retaining ring groove 343. The elastic sheet 350 is provided with an elastic protrusion 351. The elastic sheet 350 is elastic. When the filter end cover 320 is inserted into the insertion groove 341, the protrusion 321 will press the elastic sheet protrusion 351 until it passes through the elastic sheet protrusion 351. The elastic sheet protrusion 351 automatically resets under the elasticity of the elastic sheet so that the elastic sheet protrusion 351 is pressed against the top of the filter end cover 320 ( Fig.14 This can effectively prevent the filter end cover 320 from falling out of the plug-in slot 341. When the filter end cover 320 needs to be pulled out, it is only necessary to apply sufficient pulling force to the filter end cover 320 so that the protrusion 321 pushes the spring protrusion 351 until the filter end cover 320 is completely pulled out of the plug-in slot.

[0048] See also Figure 10-13 Since the filter tube 310 needs to be replaced after long-term use, it will obviously cause great waste if the connecting tube 130 and the filter tube 310 are made into one piece. Therefore, in this embodiment, the filter tube 310 and the connecting tube 130 are set to a structure that can be quickly disassembled, so that when replacing the filter tube 310, it can be directly disassembled and replaced, as follows:

[0049] A fastener 150 is installed on the connection tube 130 assembled with the filter tube 310. The fastener 150 includes a fastener sheet 151 and a fastener protrusion 152. The fastener sheet 151 is elastic. A pipe sleeve 330 is fixedly installed on the filter tube 310 and is in close contact with the end face of the corresponding connection pipe flange 131. The fastener protrusion 152 passes through the sleeve through groove 331 of the pipe sleeve 330 and is pressed against the end face of the pipe sleeve 330 away from the connection pipe flange 131, thereby realizing the assembly of the filter tube 310 and the connection tube 130. When the filter tube 310 needs to be disassembled, it is only necessary to break the fastener protrusion 152 away from the pipe sleeve 330 so that the fastener protrusion 152 does not block the pipe sleeve 330 from being pulled out. When the filter tube 310 needs to be installed, the sleeve groove 331 is aligned with the buckle protrusion 152, and then the filter tube 310 is pushed toward the corresponding connecting tube 130, so that the tube sleeve 330 squeezes and pushes the buckle protrusion 152 away until the tube sleeve 330 does not squeeze the buckle protrusion 152, and the buckle protrusion 152 is reset and pressed tightly against the tube sleeve 330 under the elastic force of the buckle piece 151.

[0050] In this embodiment, the pipe sleeves 330 can be installed only near the filter tube 310 and the retaining ring 340, and where the filter tube 310 and the connecting tube 130 are in close contact. This can not only support the filter tube, but also prevent more pipe sleeves 330 from affecting the filtration and subsequent cleaning of the filter tube.
