Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a cooling water inlet filter for an MVR plate heat exchanger. Background Art

[0002] A plate heat exchanger is a heat exchanger formed by stacking multiple corrugated stainless steel plates. It is a wall-type heat transfer device where cold / hot media exchange heat by flowing through their respective channels. The channels between the stainless steel plates are very narrow, generally 3 mm - 5 mm. When the cooling water contains relatively large solid particles or fibrous substances, it is easy to block the channels between the plates, affecting the cooling effect.

[0003] The diameter of the inlet pipe of the existing plate heat exchanger is DN50, and a pipeline Y-type filter is selected. The filtering effect is not ideal, and it is easy to block the Y-type filter. After removing the fine mesh, it is easy to block the plate heat exchanger. However, the filtering surface area of the Y-type filter is relatively small. When there are many solid particles, bacteria, and algae microorganisms in the cooling water, the filter screen will be blocked after a period of use. The cleaning frequency is relatively high. Fixed tools are required for cleaning. Frequent disassembly and cleaning are likely to cause the screws to slip, shortening its service life. At the same time, the blockage of the filter affects the heat exchange effect of the plate heat exchanger, affecting the production efficiency of the equipment. Multiple shutdowns for disassembling and cleaning the Y-type filter increase the labor hours. Secondly, the filtering effect of the Y-type filter is not good, and the plate heat exchanger is prone to fouling and blockage. Disassembling the plate heat exchanger for cleaning takes a long time. Frequent disassembly makes the seal of the plate heat exchanger worse and prone to leakage, affecting its service life.

The embodiments of the present invention will be described below according to the overall structure of the present invention

[0043] Please refer to Figures 1-11 , the present invention provides a technical solution: a cooling water inlet filter for an MVR plate heat exchanger, including:

[0044] A tank body 101, a first receiving portion 102 extends outward from the top of the tank body 101, a liquid inlet 103 is arranged at the top of the side wall of the first receiving portion 102, a liquid outlet 104 is arranged at the bottom of the tank body 101, and a fixing port 105 is arranged at the bottom inside the tank body 101;

[0045] A chassis 201, a circulation portion 202 and a diversion portion 203 are arranged at the top of the chassis 201. The diversion portion 203 and the circulation portion 202 are arranged in an interleaved manner, and the diversion portion 203 is communicated with the circulation portion 202. The diversion portion 203 is also communicated with a diversion port 204; an outer edge portion 205 extends upward from the top edge of the chassis 201, and a fixing block 206 is connected to the bottom of the chassis 201. The fixing block 206 is installed in the fixing port 105;

[0046] Two semi-cylindrical bodies 301, the two semi-cylindrical bodies 301 are butted into a cylindrical shape. A second receiving portion 302 extends outward from the top of the semi-cylindrical body 301. A plurality of liquid through holes 303 are arranged on the side wall of the semi-cylindrical body 301. A liquid through port 311 is arranged at the bottom of the semi-cylindrical body 301. The liquid through port 311 is communicated with the circulation portion 202;

[0047] A closing plate 304 is installed at the opening of the semi-cylindrical body 301. After the top of the closing plate 304 is combined with the second receiving portion 302, a clamping groove 305 is formed;

[0048] A clamping plate 306 is installed on the second receiving portion 302;

[0049] A filter screen 307 is arranged in the space formed by the combination of the semi-cylindrical body 301 and the closing plate 304. A part of the edge of the filter screen 307 is clamped between the clamping plate 306 and the second receiving portion 302, and the other part of the edge of the filter screen 307 is arranged in the clamping groove 305;

[0050] A cover body 401 is installed on the first receiving portion 102. A buckling plate 402 is installed at the bottom of the cover body 401. The buckling plate 402 is snapped into the clamping groove 305.

[0051] This cooling water inlet filter changes the Y-type filter into a tank filter, increases the filtering area, and enhances the filtering effect; at the same time, it reduces the number of disassembly times and avoids damage to the filter connection position caused by multiple disassembly; the quick-disassembly design of the filter screen 307 increases the cleaning effect.

[0052] The semi-cylindrical body 301 provided inside the device is driven to rotate by the rotating cover body 401, so as to directly replace the filter screen 307 while the filtering process is not stopped, improving the filtering effect; the setting of the chassis 201 ensures seamless diversion during the rotation of the semi-cylindrical body 301, and can discharge the filtered liquid in real time; when one of the semi-cylindrical bodies 301 is running the filtering process, the cover body 401, the semi-cylindrical body 301 and the tank body 101 can form a partial filtering space to achieve the purpose of continuous filtering; in addition, open the other cover body 401, release the clamping groove 305 and the clamping plate 306 to achieve the purpose of quickly removing the filter screen 307, put the new filter screen 307 in, and cover the cover body 401 to replace the old filter screen 307 with the new filter screen 307.

[0053] Three triangular bases 106 are connected to the bottom of the tank body 101, and the tank body 101 is supported by the triangular bases 106, which is more stable than the conventional support.

[0054] The fixing port 105 is arc-shaped and is arranged beside the liquid outlet 104. Through the connection between the fixing port 105 and the fixing block 206, the tank body 101 and the chassis 201 can be locked to prevent sliding or moving during the rotation of the semi-cylindrical body 301, resulting in abnormal filtering of the device.

[0055] The first slope 207 and the second slope 209 are arranged on the top of the chassis 201. The first slope 207 and the second slope 209 are arranged in a mirror image around the diversion port 204. The rear ends of the first slope 207 and the second slope 209 are the first inclined back 208 and the second inclined back 210 respectively; the third slope 308 is arranged at the bottom of the semi-cylindrical body 301, and the rear end of the third slope 308 is the third inclined back 309, and the third inclined back 309 is arranged opposite to the first inclined back 208 and the second inclined back 210. The settings of the first slope 207, the second slope 209 and the third slope 308 enable the semi-cylindrical body 301 and the base to rotate in only one direction. When the third inclined back 309 is in contact with the first inclined back 208 and the third inclined back 309 is in contact with the second inclined back 210, it cannot rotate clockwise, but can rotate counterclockwise. This design is mainly to facilitate the accurate removal of the semi-cylindrical body 301. For example, after rotating counterclockwise for more than half a turn, then rotate clockwise until it cannot rotate, which proves the correct position of the semi-cylindrical body 301 in the tank body 101 and keeps it in the best state all the time.

[0056] A handle 403 is installed at the top end of the cover body 401. The handle 403 is convenient for rotation.

[0057] Both the cover body 401 and the semi-cylindrical body 301 are provided with 2, and the cover body 401 and the semi-cylindrical body 301 are correspondingly arranged. Multiple sets can also be set to achieve single-cylinder multi-screen filtering and increase the applicable scenarios.

[0058] The clamping plate 306 and the second receiving portion 302 are connected by a quick-release nut 310 to achieve a quick-release effect.

[0059] The liquid inlet 103 is connected to the first pipe 501, and the liquid outlet 104 is connected to the second pipe 502. The normal operation of the filtration process is achieved through the connection of the pipes.

[0060] Working principle: The impurity liquid flows into the filter screen 307 in the tank body 101 through the first pipe 501, and after filtration, it is discharged through the liquid through holes 303 and the liquid outlet 311. The cleaning liquid flows into the diversion portion 203 through the liquid through holes 303. At the same time, the cleaning liquid flows into the circulation portion 202 through the liquid outlet 311, and finally converges at the diversion port 204 and the liquid outlet 104, and is discharged through the second pipe 502.
