During the sewage heating and evaporation treatment process, the sealing joint 5 seals the connecting joint 1 and the evaporator 2 together, connects the evaporator 2 to the sewage treatment system and performs heating and evaporation treatment on the sewage. The sewage treatment system filters, disinfects, heats and evaporates the sewage to meet the discharge standard and recycles the water in the sewage. During the cleaning process of the evaporator 2, the switching seat 6 replaces the cleaning head 3 to the position of one of the connecting joints 1 and seals it with the evaporator 2 through the sealing joint 5, and simultaneously replaces the plugging head 4 to the position of another connecting joint 1 and seals it with the evaporator 2 through the sealing joint 5, so that the evaporator 2 is connected to the cleaning system and cleaned. The cleaning system cleans the evaporator 2 to remove the evaporation. The dirt in the evaporator 2 is removed, so that the evaporator 2 is in an efficient and stable working state. After cleaning, the connecting joint 1 is reset to allow the evaporator 2 to enter the sewage treatment system to continue heating and evaporating the sewage. Through the cooperation of the sealing joint 5 and the switching seat 6, the evaporator 2 can be quickly and stably switched back and forth between the sewage treatment system and the cleaning system, which is convenient for cleaning the evaporator 2 in a regular cleaning manner, ensuring that the evaporator 2 is in an efficient and stable working state for a long time, and the sewage treatment system and the cleaning system are independent of each other and do not interfere with each other. In the process of switching and cleaning, it is only necessary to stop the transportation of sewage for a short time to quickly complete the switching and cleaning work; wherein, the switching seat 6 includes a base 61, the base 61 is symmetrically distributed on the left and right, and the base 61 is connected with a movable seat 62 for sliding up and down, and the movable seat 62 is moved up and down by an existing driving source (such as an electric slider).

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 5The connecting joint 1 is symmetrically arranged on the left and right and fixedly installed on the corresponding moving seat 62. The cleaning head 3 and the plugging head 4 are respectively installed on the two moving seats 62, and the cleaning head 3 is located below the left connecting joint 1, and the plugging head 4 is located below the right connecting joint 1. During the switching process, it is only necessary to move the moving seat 62 upward through the existing driving source to quickly exchange the position of the cleaning head 3 and the left connecting joint 1, as well as the position of the plugging head 4 and the right connecting joint 1, so that the evaporator 2 is switched from the state where the two ends are connected to the connecting joint 1 to the state where the two ends are respectively connected to the cleaning head 3 and the plugging head 4, wherein the connecting joint 1 is a straight-through pipeline, and the left end of the left connecting joint 1 is The end is sealed and connected with a feed head 7, and the right end is sealed and connected with the left end of the evaporator 2. The right end of the right connecting joint 1 is sealed and connected with a discharge head 8, and the left end is sealed and connected with the right end of the evaporator 2. Both the feed head 7 and the discharge head 8 are connected with a telescopic pipe 9. During the switching process, the feed head 7 and the discharge head 8 move with the connecting joint 1. There is no need to disassemble the feed head 7 and the discharge head 8. The telescopic pipe 9 automatically adapts to the position change of the feed head 7 and the discharge head 8. The sewage is transported to the feed head 7 by the telescopic pipe 9 on the left and then enters the evaporator 2 through the connecting joint 1. The concentrated liquid after heating and evaporation treatment in the evaporator 2 passes through the discharge head 8 and flows out from the telescopic pipe 9 on the right.

[0031] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The sealing joint 5 includes a sealing seat 51 and a sealing head 52. The sealing heads 52 are symmetrically distributed on the left and right and are respectively arranged at the corresponding ports of the evaporator 2. The connecting joint 1, the cleaning head 3 and the plugging head 4 are all provided with sealing seats 51. The connecting joint 1 and the evaporator 2, the cleaning head 3 and the evaporator 2, and the plugging head 4 and the evaporator 2 are sealed and connected together through the cooperation of the sealing head 52 and the sealing seat 51.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The sealing head 52 includes a fixed sealing ring 521, a sliding sealing ring 522 and a control component 523. The fixed sealing ring 521 is fixedly installed at the corresponding port of the evaporator 2. The sliding sealing ring 522 moves in the axial direction of the evaporator 2 and is in close contact with the fixed sealing ring 521 and the sealing seat 51 at the same time. The control component 523 is used to control the sliding sealing ring 522 to move in the axial direction of the evaporator 2 and lock the sliding sealing ring 522, the fixed sealing ring 521 and the sealing seat 51 in a sealed connection state. The control component 523 controls the sliding sealing ring 522 to move in the axial direction to control the sealing connection and disconnection between the evaporator 2 and the connecting joint 1, the cleaning head 3 and the plugging head 4. On the basis of ensuring the connection sealing of the evaporator 2, the efficiency of regular cleaning of the evaporator 2 is improved. Among them, the control component 523 includes a fastener 5231 and The pressing piece 5232 and the fastener 5231 are evenly distributed along the circumference of the sliding sealing ring 522 and are used to fasten the sliding sealing ring 522 and the sealing seat 51 on the connecting joint 1 together, ensuring that during the sewage evaporation treatment process, the evaporator 2 and the connecting joint 1 are in a stable sealed connection state for a long time. The pressing piece 5232 is used to press and seal the sliding sealing ring 522 with the corresponding sealing seat 51 on the cleaning head 3 and the corresponding sealing seat 51 on the plugging head 4 together, and on the basis of ensuring that the evaporator 2 is in a sealed connection state with the cleaning head 3 and the plugging head 4 in the cleaning system, further reduce the complexity of switching the evaporator 2 back and forth between the cleaning system and the sewage treatment system, and then on the basis of fully ensuring the sealed connection state of the evaporator 2, effectively improve the convenience of the switching process of the evaporator 2 and the switching efficiency. Among them, the clamping piece 5232 is a cylinder and is installed on the evaporator 2. In the process of the fastener 5231 fastening the sliding sealing ring 522 and the connecting joint 1 together, the clamping piece 5232 can assist the fastening connection of the fastener 5231, improve the convenience, efficiency and quality of the fastening connection of the fastener 5231, that is, first move the sliding sealing ring 522 through the clamping piece 5232 until the sliding sealing ring 522 is in a state of being pressed and sealed with the fixed sealing ring 521 and the sealing seat 51, and then fasten the sliding sealing ring 522 and the sealing seat 51 together through the fastener 5231.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The sliding sealing ring 522 is provided with an axial sealing surface 524 and a radial sealing surface 525. The axial sealing surface 524 is inclined. In the sealed state, the fixed sealing ring 521 and the sealing seat 51 are both sealedly connected with the axial sealing surface 524 and the radial sealing surface 525 on the sliding sealing ring 522 at the same time, and radial sealing areas and axial sealing areas are formed accordingly, ensuring the reliability and stability of the sealing connection.

[0034] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The sealing seat 51 includes a sealing ring groove 511 and a convex ring platform 512 located in the sealing ring groove 511. An inlay ring groove 526 corresponding to the convex ring platform 512 is opened on the sliding sealing ring 522, and the circumferential surfaces of the convex ring platform 512 and the inlay ring groove 526 are both inclined. The fastener 5231 fastens the sliding sealing ring 522 and the convex ring platform 512 together. When the sealing joint 5 is sealed, the convex ring platform 512 and the inlay ring groove 526 fit together to form a radial sealing area and two axial sealing areas. On the one hand, the stability and reliability of the sealing connection of the sealing joint 5 are further improved. On the other hand, the stability of the connection between the sliding sealing ring 522 and the sealing seat 51 and the integrity of the overall structure are effectively improved. Secondly, the inclined setting of the axial sealing surface 524 effectively reduces the friction generated between the sliding sealing ring 522 and the fixed sealing ring 521 and the sealing seat 51 during the reciprocating movement, which is beneficial to improving the stability of the sealing head 51 and the sealing seat 52 in long-term use.

[0035] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The cleaning head 3 includes a sliding seat 32 provided with an end face brush head 31 and a disc seat 34 provided with a plurality of flushing heads 33. The sliding seat 32 is slidably mounted on the corresponding moving seat 62 forward and backward, and the disc seat 34 is fixedly mounted on the corresponding moving seat 62. The disc seat 34 is located below the sliding seat 32, and the corresponding sealing seat 51 is mounted on the disc seat 34. During the upward movement of the moving seat 62, the end face brush head 31 moves back and forth as the switching seat 6 moves upward to perform preliminary cleaning of the end face of the evaporator 2. During the sewage treatment process of the evaporator 2, the left end face is more likely to generate dirt due to the low water flow rate and the initial contact of the sewage with the evaporator 2. Therefore, preliminary cleaning is performed in advance, which is helpful for the subsequent full and efficient removal of dirt in the evaporator 2. When the disc seat 34 moves to a position facing the left end of the evaporator 2, the moving seat 62 stops moving, and then the sealing head 52 at the left end of the evaporator 2 and the disc seat 34 are moved upward. The sealing seat 51 cooperates with the disk seat 34 to seal and connect the evaporator 2 together. At the same time, the sealing head 52 at the right end of the evaporator 2 cooperates with the sealing seat 51 on the plugging head 4 to seal and connect the plugging head 4 to the evaporator 2. At this time, the evaporator 2, the disk seat 34 and the plugging head 4 constitute a relatively independent cleaning area. The evaporator 2 can be flushed by starting the flushing head 33. The corresponding dissolving cleaning liquid is selected according to the dirt. The plugging head 4 is provided with a liquid outlet. The flushing liquid flows out from the liquid outlet after passing through the evaporator 2. The evaporator 2 includes a base 21 and a plurality of heating pipes 22. The flushing heads 33 correspond to the heating pipes 22 one by one and are distributed on the disk seat 34 corresponding to the distribution state of the heating pipes 22 on the base 21. When the disk seat 34 is aligned with the left end of the evaporator 2, the flushing head 33 corresponds to the corresponding heating pipe 22. Starting the flushing head 33 can quickly and efficiently clean out the dirt in the heating pipe 22.

[0036] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9A mounting groove 37 is provided on the end surface of the disk seat 34 close to the evaporator 2, and the flushing heads 33 are all installed in the mounting groove 37. A liquid injection port 38 and a liquid discharge port 39 are provided on the side wall of the mounting groove 37. The liquid injection ports 38 are symmetrically distributed front and back, and the liquid discharge port 39 is located at the bottom of the mounting groove 37. Valves are installed at the liquid discharge port 39 and the liquid outlet on the plugging head 4; the liquid outlet, the liquid injection port 38 and the liquid discharge port 39 on the plugging head 4 are all connected with pipelines, and the pipelines pass through the corresponding movable seat 62 and the base 61 in sequence, and the part of the pipeline located between the movable seat 62 and the base 61 is a hose section to adapt to the up and down movement of the movable seat 62. The second sliding body 322 is a cavity structure and is connected to the pipeline connected to the liquid injection port 38 through a connecting pipe. The liquid injection port 38 is connected to the liquid discharge port 39. After the pipeline passes through the base 61, it is connected to the existing external cleaning liquid pumping equipment; during the cleaning process, the dissolving cleaning liquid is first quickly injected into the cleaning area through the liquid injection port 38 to fully immerse the dirt in the dissolving cleaning liquid. After that, the valve is opened to discharge the dissolving cleaning liquid in the cleaning area and start the flushing head 33 to quickly and efficiently clean out the dirt. Soaking the dirt in the dissolving cleaning liquid is beneficial to accelerate the decomposition of the dirt, shorten the flushing time and fully clean out the dirt, which is beneficial to fully and efficiently cleaning the dirt in the evaporator 2 as a whole. Among them, when the dirt is immersed in the dissolving cleaning liquid, heating the dissolving cleaning liquid can accelerate the speed and effect of dissolution, and the heating of the dissolving cleaning liquid can be carried out by arranging a heating rod on the disc seat 34.

The reciprocating movement of the first sliding body 321 can synchronously drive the second sliding body 322 to reciprocate through the rack and gear set 323, so that the flushing part 312 on the second sliding body 322 generates a changed water flow to the end of the evaporator 2 The surface is rinsed to improve the effect of preliminary cleaning, wherein a guide groove 35 is arranged on the movable seat 62, and a flexible guide eaves 36 is arranged on the guide groove 35. In the process of the end face brush head 31 performing preliminary cleaning on the end face of the evaporator 2, the flexible guide eaves 36 are closely attached to the corresponding end face of the evaporator 2, so that the liquid after the end face is rinsed by the flushing part 312 flows along the flexible guide eaves 36 to the guide groove 35, effectively preventing the liquid after flushing from flowing to the disc seat 34 and affecting the stability and reliability of the sealing connection of the sealing seat 51 on the disc seat 34.
