Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger cleaning, and more particularly to a high-efficiency and energy-saving heat exchanger which is easy to clean. Background Art

[0002] A heat exchanger is a heat exchange device, which is mainly used to transfer heat between fluids at different temperatures. Common heat exchangers are mainly composed of heat exchangers, pipe systems, water pumps, valves and metering devices. The specific working process of the heat exchanger is as follows: start the water pump to transport the fluid to be processed to the heat exchanger through the pipe system. In the heat exchanger, the cold fluid and the hot fluid exchange heat through the heat transfer surface of the heat exchanger. The fluid after heat exchange is discharged from the heat exchange system through the pipe system. During the entire heat exchange process, it is necessary to continuously monitor the flow, pressure, temperature, liquid level and other parameters of the fluid, and adjust the operating status of the heat exchanger in time according to the monitoring results; As the use time increases, various impurities may accumulate inside the heat exchanger, such as dirt, particulate matter, microorganisms, etc. These impurities will affect the heat exchange efficiency of the heat exchanger and even cause equipment failure. Therefore, the heat exchanger is filtered to remove these impurities. A common filtering method is to install a filter plate inside the pipeline to achieve the effect of impurity filtering. However, in long-term observations, we found that some of the impurities remain on the surface of the filter plate. The accumulation of impurities on the surface of the filter plate will form a blocking layer, which increases the resistance of water flow through the filter plate, thereby increasing the pressure loss when the water flows through the filter plate, reducing the flow rate and pressure of the water flow, and affecting the operation efficiency of the entire system. In the prior art, the surface of the filter plate is mainly scraped by external force to clean the impurities remaining on the surface of the filter plate. However, in actual operation, we found that the impurities in the filter holes of the filter plate cannot be cleaned, which reduces the working efficiency of the filter plate, thereby affecting the transportation efficiency of the overall system to a certain extent, causing certain economic losses; Therefore, there is an urgent need for a high-efficiency and energy-saving heat exchanger that is easy to clean to solve the above-mentioned problems.

[0032] Reference Figure 4 and Figures 6 to 11 As shown, the present invention provides a high-efficiency and energy-saving heat exchanger that is easy to clean. The cleaning mechanism 4 includes a first limit support plate 401, a second limit support plate 402 and a rubber ring 403. The first limit support plate 401 and the second limit support plate 402 are installed on the side of the filter mechanism 3 in a vertical and parallel state. The inner walls of the first limit support plate 401 and the second limit support plate 402 are both installed with electric lifting columns 408. One end of the electric lifting column 408 is installed with a hollow plate 405. The inner wall of the hollow plate 405 is movably sleeved with a scraping plate 409. The bottom of the scraping plate 409 is installed with a spring. The number of the scraping plates 409 is multiple groups, and the multiple groups of scraping plates 409 are sleeved. Both sides of the hollow plate 405 are movably sleeved on the inner wall of the slide rail plate 404. The scraping plates 409 arranged on the inner walls of the first limiting support plate 401 and the second limiting support plate 402 are in contact with the surface of the filter plate 301, and the side of the scraping plate 409 is installed with a rubber plate 406, and the top of the rubber plate 406 installed inside the second limiting support plate 402 is connected with an adsorption tube 411, and the adsorption air generated by the dust removal device 2 is transported to the surface of the filter plate 301 through the rubber plate 406 and the adsorption tube 411 for adsorbing impurities after scraping, and the side of the top of the hollow plate 405 installed inside the second limiting support plate 402 is installed with an air pressure monitor 410, and a control module is installed inside the air pressure monitor 410; The bottom of the rubber plate 406 installed inside the first limiting support plate 401 is connected through a delivery branch pipe 407. The dust removal device 2 generates compressed air and delivers it to the rubber plate 406 and the delivery branch pipe 407 to the filter holes of the filter plate 301 for cleaning impurities in the filter holes.

[0033] In the embodiment of the present application, the specific working process of the embodiment of this part of the application is as follows: when the filter plate 301 is being cleaned, both sets of electric lifting columns 408 are input with current to control the two sets of hollow plates 405 to move toward the surface of the filter plate 301, and a set of rubber plates 406 is in a stretched state, thereby controlling the delivery branch pipe 407 to move to the filter hole of the filter plate 301. After the two sets of rubber plates 406 move to the specified position, the two sets of rubber plates 406 and the rubber ring 403 will form an isolation space, and the filter plate 301 is in the middle position of the isolation space. The dust removal device 2 first generates compressed air through the first Y-shaped tube 2031 and the rubber plate 406. The conveying branch pipe 407 conveys the air to the inside of the filter hole, and performs a wind cleaning operation on the impurities in the filter hole of the filter plate 301. At the same time, the dust removal device 2 generates adsorbed air and inputs it into another group of rubber plates 406 through the second Y-shaped pipe 2041, and inputs it to the surface of the filter plate 301 through the adsorption pipe 411 to adsorb the cleaned impurities. After the filter plate 301 is cleaned, one group of rubber plates 406 returns to its original position, and the adsorbed air in the other group of rubber plates 406 is continuously conveyed to the outer wall of the filter plate 301 through the adsorption pipe 411, which is conducive to the continuous cleaning of the impurities cleaned from the outer walls of both sides of the filter plate 301. During the movement of the two sets of hollow plates 405, the scraping plates 409 scrape the outer walls of both sides of the filter plate 301 to scrape and clean the impurities on the outer walls of the filter plate 301; At the same time, after the cleaning mechanism 4 completes the first scratch cleaning of the filter plate 301, the two groups of electric lifting columns 408 input current to control the two groups of rubber plates 406 to attach to the outer wall of the filter plate 301 again. At the same time, the dust removal device 2 inputs compressed air into the isolation space formed by the two groups of rubber plates 406. The air pressure monitor 410 monitors the air pressure data in the isolation space in real time and transmits it to the control module. The control module analyzes and determines whether the filter holes of the filter plate 301 are damaged, or whether the filter holes and one side of the filter plate 301 are not thoroughly cleaned.

[0034] Reference Figures 1 to 11As shown, the air pressure monitor 410 collects the air pressure data in the isolation space formed by the two groups of rubber plates 406 and transmits it to the control module. The control module includes a threshold end and a light reminder device. The threshold end is manually inputted by the air pressure monitor 410 when the filter plate 301 is in a normal working state. The control module compares the real-time air pressure data with the threshold air pressure data. When the real-time air pressure data is greater than the threshold air pressure data, the control module determines that the filter plate 301 filter holes and one side are not cleaned thoroughly, and the control module drives the dust removal device 2 and the cleaning mechanism 4 to perform a secondary cleaning operation on the filter plate 301. When the real-time air pressure data is less than the threshold range, it can be determined that the filter hole or one side of the filter plate 301 is damaged, and the control module reminds the on-site staff to check through the light reminder device.

[0035] The specific workflow of this application is as follows: Step 1: Under the action of the pump, the liquid is input into the main body 101 through the input pipe 104 to perform heat exchange. The exchanged liquid is discharged through the output pipe 103. At the same time, the filter mechanism 3 performs impurity filtering on the input liquid. The dust removal device 2 generates gas and transports it to the cleaning mechanism 4, driving the cleaning mechanism 4 to clean the impurities on the surface of the filter mechanism 3. Step 2: Cleaning the surface of the filter mechanism 3. The air pump 205 inputs current to generate compressed air, which is transported to the inside of the cleaning mechanism 4 through the first delivery pipe 203 and the first Y-shaped pipe 2031, and the cleaning mechanism 4 assists in cleaning the impurities on the surface of the filter mechanism 3. The adsorption pump 202 generates adsorption air, which is transported to the cleaning mechanism 4 through the dust removal box 201, the second delivery pipe 204 and the second Y-shaped pipe 2041, and adsorbs the cleaned impurities, so that the cleaned impurities are stored in the dust removal box 201, which is convenient for the staff to recycle them later. Step 3: When the filter plate 301 is being cleaned, both sets of electric lifting columns 408 are input with current to control the two sets of hollow plates 405 to move toward the surface of the filter plate 301, and one set of rubber plates 406 is in a stretched state, thereby controlling the delivery branch pipe 407 to move to the filter hole of the filter plate 301. After the two sets of rubber plates 406 move to the specified position, the two sets of rubber plates 406 and the rubber ring 403 will form an isolation space, and the filter plate 301 is in the middle of the isolation space. The dust removal device 2 first generates compressed air to pass through the first Y-shaped tube 2031, the rubber plate 406 and the delivery branch pipe 407 to The impurities in the filter holes of the filter plate 301 are transported by wind. At the same time, the dust removal device 2 generates adsorbed air which is input into the inside of another group of rubber plates 406 through the second Y-shaped tube 2041, and then input into the surface of the filter plate 301 through the adsorption tube 411 to adsorb the cleaned impurities. After the filter plate 301 is cleaned, one group of rubber plates 406 returns to its original position, and the adsorbed air in the other group of rubber plates 406 is continuously transported to the outer wall of the filter plate 301 through the adsorption tube 411, which is conducive to the continuous cleaning of the impurities cleaned from the outer walls of both sides of the filter plate 301. During the movement of the two sets of hollow plates 405, the scraping plates 409 scrape the outer walls of both sides of the filter plate 301 to scrape and clean the impurities on the outer walls of the filter plate 301; At the same time, after the cleaning mechanism 4 completes the first scratch cleaning of the filter plate 301, the two groups of electric lifting columns 408 input current to control the two groups of rubber plates 406 to attach to the outer wall of the filter plate 301 again. At the same time, the dust removal device 2 inputs compressed air into the isolation space formed by the two groups of rubber plates 406. The air pressure monitor 410 monitors the air pressure data in the isolation space in real time and transmits it to the control module. The control module analyzes and determines whether the filter holes of the filter plate 301 are damaged, or whether the filter holes and one side of the filter plate 301 are not thoroughly cleaned.

The high-efficiency energy-saving heat exchanger that is easy to clean according to claim 5, characterized in that: A delivery branch pipe (407) is connected through the bottom of the rubber plate (406) installed inside the first limit support plate (401), and the dust removal device (2) generates compressed air and delivers it to the rubber plate (406) and the delivery branch pipe (407) to the filter holes of the filter plate (301) for cleaning impurities in the filter holes.

7. The energy-saving and high-efficiency heat exchanger that is easy to clean according to claim 5, characterized in that: The air pressure monitor (410) collects air pressure data in the isolation space formed by the two groups of rubber plates (406) and transmits the data to the control module. The control module comprises a threshold end and a light reminder device. The threshold end manually inputs the threshold air pressure data generated by the air pressure monitor (410) when the filter plate (301) is in a normal working state. The control module compares the real-time air pressure data with the threshold air pressure data. When the real-time air pressure data is greater than the threshold air pressure data, the control module determines that the filter holes and one side of the filter plate (301) are not cleaned thoroughly. The control module drives the dust removal device (2) and the cleaning mechanism (4) to perform a secondary cleaning operation on the filter plate (301); When the real-time air pressure data is less than the threshold range, it can be determined that the filter hole or one side of the filter plate (301) is damaged, and the control module reminds the on-site staff to check through the light reminder device.
