When it is necessary to clean the inside of the heater body 1, first add 5% concentration alkali solution into the inside of the circulating liquid storage tank 2, then heat the alkali solution inside the circulating liquid storage tank 2 through the steam heating inlet pipe 404 and the steam heating outlet pipe 403, observe the temperature of the alkali solution through the thermometer 405 to make it reach above 80℃, then start the circulation pump 410, at this time, the circulation pump 410 extracts the 5% concentration alkali solution inside the circulating liquid storage tank 2 through the pump inlet pipe 408 and then pumps it through the inlet sampling pipe 402 The alkali solution flows into the interior of the heater body 1, and the refluxed alkali solution flows into the interior of the circulating liquid storage tank 2 through the outlet sampling tube 401. Since one end of the outlet sampling tube 401 is inserted into the interior of the installation frame 3, a filter screen 409 is installed inside the installation frame 3. At this time, the filter screen 409 filters the refluxed alkali solution. At this time, the interior of the heater body 1 is circulated and alkaline washed. The cleaning effect is judged by observing whether the refluxed alkali solution carries scale through the observation window 406. When the refluxed alkali solution no longer carries scale, the cleaning effect is achieved. Then, pure water is used for neutralization to make the pH value of the circulating liquid reach 7, and the cleaning is ended.

The mounting groove 501, the chute 502, the movable groove 503, the limit groove 504, the spring 505, the limit block 506 and the wrench 507 are provided with a mounting groove 501 on one side of the surface, the chute 502 is provided on one side of the surface of the circulating liquid storage tank 2, and the inside of the circulating liquid storage tank 2 is provided with a The movable groove 503 has a limiting groove 504 on one side of the surface of the mounting frame 3. A spring 505 is provided inside the movable groove 503. One end of the spring 505 is fixedly connected to the limiting block 506. A wrench 507 is fixedly connected to one side of the surface of the limiting block 506. Through the arrangement of the mounting groove 501, the sliding groove 502, the movable groove 503, the limiting groove 504, the spring 505, the limiting block 506 and the wrench 507, when in use, when the filter 409 is impurities When the filter screen 409 is cleaned or replaced, the limit block 506 loses its limiting effect on the installation frame 3, so that the filter screen 409 can be cleaned or replaced, and the installation frame 3 can be placed in the installation slot 501. At this time, the limit slot 504 is aligned with the position of the movable slot 503, and the force applied to the wrench 507 is then released. At this time, the spring 505 rebounds and deforms to drive the limit block 506 to return to its original position. At this time, one end of the limit block 506 is embedded in the movable slot 503 and the other end is embedded in the limit slot 504, so that the limit block 506 fixes the installation frame 3 to the surface of the circulating liquid storage tank 2.

[0028] Working principle: When it is necessary to clean the inside of the heater body 1, first add 5% concentration alkali solution into the inside of the circulating liquid storage tank 2, then heat the alkali solution inside the circulating liquid storage tank 2 through the steam heating inlet pipe 404 and the steam heating outlet pipe 403, observe the temperature of the alkali solution through the thermometer 405 to make it reach above 80℃, then start the circulating pump 410, at this time, the circulating pump 410 extracts the 5% concentration alkali solution inside the circulating liquid storage tank 2 through the pump inlet pipe 408 and then samples it through the inlet The pipe 402 is pumped into the interior of the heater body 1, and the refluxed alkali solution flows into the interior of the circulating liquid storage tank 2 through the outlet sampling pipe 401. Since one end of the outlet sampling pipe 401 is inserted into the interior of the installation frame 3, a filter 409 is installed inside the installation frame 3. At this time, the filter 409 filters the refluxed alkali solution. At this time, the interior of the heater body 1 is circulated and alkali-washed. The cleaning effect is judged by observing whether the refluxed alkali solution carries scale through the observation window 406. When the refluxed alkali solution no longer carries scale, the cleaning effect is achieved. The cleaning effect is achieved, and then the pure water is neutralized to make the pH value of the circulating liquid concentration reach 7, and the cleaning is completed. When the filter 409 is blocked by impurities, the wrench 507 can be moved. At this time, the wrench 507 drives the limit block 506 to slide inside the movable groove 503, and the wrench 507 slides inside the slide groove 502. At the same time, the spring 505 is compressed and deformed. When one end of the limit block 506 is out of the limit groove 504, the limit block 506 loses its limiting effect on the installation frame 3, so that the installation frame 3 can be taken out. The filter screen 409 can be cleaned or replaced, and then the installation frame 3 is placed inside the installation groove 501. At this time, the position of the limit groove 504 is aligned with the position of the movable groove 503, and then the force applied to the wrench 507 is released. At this time, the spring 505 rebounds and deforms to drive the limit block 506 to return to its original position. At this time, one end of the limit block 506 is embedded in the inside of the movable groove 503 and the other end is embedded in the inside of the limit groove 504, so that the limit block 506 fixes the installation frame 3 on the surface of the circulating liquid storage tank 2.
