Description

Technical Field

[0001] This application relates to the field of plate heat exchangers, and more specifically, to a self-cleaning plate heat exchanger. Background Technology

[0002] A plate heat exchanger is a high-efficiency heat exchange device composed of a series of corrugated metal plates stacked together. It is mainly used for heat exchange between liquid-liquid and liquid-vapor media. The thin metal plates form parallel flow channels, and the hot and cold fluids flow between adjacent plates. Heat is exchanged through the conduction of the plates, thus achieving the purpose of heat exchange.

[0003] However, existing plate heat exchangers still have the following shortcomings in use: Because the liquid flow pipes of existing plate heat exchangers are usually located inside multiple sets of metal plates, the pipes are not easy to disassemble for cleaning. Therefore, a filter chamber is usually set before the liquid enters the pipe to filter impurities in the liquid and prevent impurities from entering the pipe and adhering to the inner wall of the pipe. Existing filter chambers usually have filter plates inside to intercept impurities. However, when cleaning the filter plates of existing filter chambers, the filter plates must be manually disassembled, which makes the filter plate cleaning process time-consuming and laborious. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a self-cleaning plate heat exchanger, which aims to improve the problem that the existing filter chambers require manual disassembly of the filter plates for cleaning, resulting in a time-consuming and labor-intensive filter plate cleaning process.

[0005] This application provides a self-cleaning plate heat exchanger for cleaning the filter plates connected inside the filter chamber. The filter chamber is provided with a cleaning mechanism for cleaning the filter plates that intercept impurities, and a collection mechanism for collecting impurities is provided on one side of the filter chamber. The cleaning mechanism includes a movable plate, a scraper connected to one side of the movable plate, a first chamfer on one side of the scraper, and the bottom of the scraper being in close contact with the top of the filter plate.

[0006] In the above implementation process, by setting up a movable plate, the movement of the movable plate can be controlled to drive the scraper to move, and the scraper can clean the impurities intercepted on the top of the filter plate.

[0007] In one specific implementation, a first cavity is connected to one side of the filter chamber, a motor is connected to one end of the first cavity, the output shaft of the motor passes through the first cavity and is connected to a threaded rod, a threaded seat is threadedly connected to the outer surface of the threaded rod, and the threaded seat is connected to one end of the movable plate.

[0008] In the above implementation process, by setting up the motor, the output shaft of the motor can be controlled to rotate, which drives the threaded rod to rotate inside the first cavity, drives the threaded seat to move, and drives the moving plate to move.

[0009] In one specific implementation, a second cavity is connected to the other side of the filter chamber, a crossbar is connected inside the second cavity, a sliding member is slidably connected to the outer surface of the crossbar, the sliding member is connected to the other end of the moving plate, and baffles are connected inside both the first cavity and the second cavity.

[0010] In the above implementation process, the crossbar can be set so that when the moving plate moves, the sliding member can slide on the outer surface of the crossbar, so that the moving member can move horizontally stably. The baffle can prevent the solution from entering the interior of the first and second chambers.

[0011] In one specific implementation, the collection mechanism includes a collection box connected to the outer surface of the filter chamber, and a through hole is provided on one side of the collection box, through which the collection box communicates with the filter chamber.

[0012] In the above implementation process, by setting through holes, the scraper can push impurities into the interior of the collection box through the through holes, and the collection box collects the impurities.

[0013] In one specific implementation, the top of the collection box is connected to an installation component, the top of the installation component is connected to an electric telescopic rod, a lifting plate is provided above the installation component, two sets of vertical rods are connected to the bottom of the lifting plate, the other end of the vertical rods passes through the installation component and is connected to a horizontal plate, a partition is connected to the bottom of the horizontal plate, and a spring is sleeved on the outer surface of the vertical rods.

[0014] In the above implementation process, by setting up an electric telescopic rod, the extension of the electric telescopic rod can be controlled to drive the lifting plate to move upward, drive the vertical rod to move upward, drive the horizontal plate to move upward, compress the spring, and drive the partition to move upward.

[0015] In one specific implementation, one end of the partition is movably inserted into the inside of the collection box, and the partition is disposed on one side of the through hole, with a second chamfer at one end of the partition.

[0016] In the above implementation process, by setting the partition, the through hole can be opened after the partition moves upward, allowing impurities to enter the interior of the collection box through the through hole. The other end of the electric telescopic rod is not connected to the lifting plate. When the electric telescopic rod is shortened, the lifting plate drives the partition to move downward under the action of the elastic potential energy released by the spring. The second chamfer of the partition comes into contact with the first chamfer of the scraper. As the scraper gradually moves away from the through hole, the partition slowly moves downward, which can clean the first chamfer and prevent impurities from adhering to the surface of the first chamfer.

[0017] In one specific implementation, a plate heat exchanger is provided below the filter chamber. The plate heat exchanger includes two sets of inlets and two sets of outlets, and the inlets are connected to the filter chamber.

[0018] In the above implementation process, the filter chamber can be set up to filter the solution entering the inlet and prevent impurities from adhering to the inner wall of the pipe.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a cleaning mechanism and a collection mechanism, the output shaft of the motor can be controlled to rotate, driving the threaded rod to rotate inside the first cavity, moving the threaded seat, and moving the moving plate. The scraper cleans the impurities intercepted on the top of the filter plate. Simultaneously, by controlling the extension of the electric telescopic rod, the lifting plate moves upward, the vertical rod moves upward, and the horizontal plate moves upward, causing the spring to compress and the partition to move upward, opening the through hole. This allows the scraper to push the impurities through the through hole into the collection box, where the impurities are collected. Then, the system controls... When the electric telescopic rod is shortened, the lifting plate, under the action of the spring releasing elastic potential energy, drives the partition plate downward, so that the second chamfer of the partition plate contacts the first chamfer of the scraper. Then, by controlling the motor to reverse, the scraper is driven to gradually move away from the through hole. The partition plate slowly moves downward, which can clean the first chamfer and prevent impurities from adhering to the surface of the first chamfer. The filter plate can be cleaned automatically without disassembling it. This solves the problem that the filter plate must be manually disassembled for cleaning in existing filter chambers, which makes the filter plate cleaning process time-consuming and laborious.

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This application provides a self-cleaning plate heat exchanger for cleaning the filter plates 7 connected inside the filter chamber 6. The filter chamber 6 is provided with a cleaning mechanism 2 for cleaning the filter plates 7 that intercept impurities, and a collection mechanism 3 for collecting impurities is provided on one side of the filter chamber 6.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The cleaning mechanism 2 includes a movable plate 209, a scraper 2010 connected to one side of the movable plate 209, a first chamfer 2011 on one side of the scraper 2010, and the bottom of the scraper 2010 closely attached to the top of the filter plate 7. By setting the movable plate 209, the scraper 2010 can be moved by controlling the movable plate 209 to clean the impurities intercepted on the top of the filter plate 7.

[0026] In a specific configuration, a first chamber 201 is connected to one side of the filter chamber 6, and a motor 203 is connected to one end of the first chamber 201. The output shaft of the motor 203 passes through the first chamber 201 and is connected to a threaded rod 204. A threaded seat 205 is threadedly connected to the outer surface of the threaded rod 204. The threaded seat 205 is connected to one end of the moving plate 209. By controlling the output shaft of the motor 203 to rotate, the threaded rod 204 can be rotated inside the first chamber 201, which in turn moves the threaded seat 205 and the moving plate 209.

[0027] In the specific configuration, a second chamber 202 is connected to the other side of the filter chamber 6. A crossbar 206 is connected inside the second chamber 202. A sliding member 207 is slidably connected to the outer surface of the crossbar 206. The sliding member 207 is connected to the other end of the moving plate 209. Baffles 208 are connected inside both the first chamber 201 and the second chamber 202. The crossbar 206 allows the sliding member 207 to slide on the outer surface of the crossbar 206 when the moving plate 209 moves, enabling the moving member to move horizontally stably. The baffles 208 prevent the solution from entering the interior of the first chamber 201 and the second chamber 202.

[0028] In a specific configuration, the collection mechanism 3 includes a collection box 301, which is connected to the outer surface of the filter chamber 6. A through hole 302 is provided on one side of the collection box 301, and the collection box 301 is connected to the filter chamber 6 through the through hole 302. The through hole 302 allows the scraper 2010 to push impurities into the interior of the collection box 301 through the through hole 302, and the collection box 301 collects the impurities.

[0029] In the specific setup, the top of the collection box 301 is connected to the mounting component 303, the top of the mounting component 303 is connected to the electric telescopic rod 308, a lifting plate 304 is set above the mounting component 303, and two sets of vertical rods 305 are connected to the bottom of the lifting plate 304. The other end of the vertical rod 305 passes through the mounting component 303 and is connected to the horizontal plate 309. The bottom of the horizontal plate 309 is connected to the partition plate 307. A spring 306 is sleeved on the outer surface of the vertical rod 305. The electric telescopic rod 308 can be extended by controlling the electric telescopic rod 308 to drive the lifting plate 304 to move upward, drive the vertical rods 305 to move upward, drive the horizontal plate 309 to move upward, compress the spring 306, and drive the partition plate 307 to move upward.

[0030] In the specific configuration, one end of the partition 307 is movably inserted into the inside of the collection box 301, and the partition 307 is located on one side of the through hole 302. One end of the partition 307 has a second chamfer 3010. The partition 307 allows the through hole 302 to be opened after it moves upward, allowing impurities to enter the inside of the collection box 301 through the through hole 302. The other end of the electric telescopic rod 308 is not connected to the lifting plate 304. When the electric telescopic rod 308 is shortened, the lifting plate 304, under the action of the elastic potential energy released by the spring 306, drives the partition 307 to move downward. The second chamfer 3010 of the partition 307 contacts the first chamfer 2011 of the scraper 2010. As the scraper 2010 gradually moves away from the through hole 302, the partition 307 slowly moves downward, cleaning the first chamfer 2011 and preventing impurities from adhering to the surface of the first chamfer 2011.

[0031] In the specific setup, a plate heat exchanger 1 is installed below the filter chamber 6. The plate heat exchanger 1 includes two sets of inlets 4 and two sets of outlets 5. The inlets 4 are connected to the filter chamber 6. The filter chamber 6 can filter the solution entering the inlet 4 to prevent impurities from adhering to the inner wall of the pipe.

[0032] The working principle of this self-cleaning plate heat exchanger is as follows: When using the self-cleaning plate heat exchanger, the output shaft of the motor 203 rotates, driving the threaded rod 204 to rotate inside the first cavity 201, which in turn moves the threaded seat 205 and the moving plate 209. The scraper 2010 cleans the impurities intercepted at the top of the filter plate 7. Simultaneously, the electric telescopic rod 308 extends, causing the lifting plate 304 to move upwards, the vertical rod 305 to move upwards, and the horizontal plate 309 to move upwards. This compresses the spring 306, causing the partition plate 307 to move upwards, opening the through hole 302. The scraper 2010 then pushes the impurities through the through hole 302 into the collection box 301, where they are collected. Finally, the electric... When the telescopic rod 308 is shortened, the lifting plate 304, under the action of the elastic potential energy released by the spring 306, drives the partition 307 to move downward, so that the second chamfer 3010 of the partition 307 contacts the first chamfer 2011 of the scraper 2010. Then, by controlling the motor 203 to reverse, the scraper 2010 is driven to gradually move away from the through hole 302. The partition 307 moves downward slowly, which can clean the first chamfer 2011 and prevent impurities from adhering to the surface of the first chamfer 2011. The cleaning of the filter plate 7 can be completed automatically without disassembling the filter plate 7. This solves the problem that when the existing filter chamber 6 cleans the filter plate 7, the filter plate 7 must be manually disassembled to clean it, which makes the cleaning process of the filter plate 7 time-consuming and laborious.

[0033] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
