[0034] As mentioned in the background technology, after low-temperature evaporation equipment is used to perform low-temperature evaporation and concentration treatment on industrial wastewater, waste residues such as concentrated substances are usually adhered to the inner wall of the low-temperature evaporation equipment. If not cleaned in time, these substances may be deposited on the inner wall, affecting the normal use of the low-temperature evaporation equipment, which leads to the need for frequent cleaning and maintenance of the low-temperature evaporation equipment.

[0038] In some embodiments, the stirring assembly 2 further includes a connecting joint 21, which is used to connect to an external pipeline for providing a cleaning fluid, and the connecting joint 21 is in communication with the stirring shaft 22, so that the cleaning fluid can be delivered to the inner cavity of the stirring shaft 22 through the connecting joint 21. In some embodiments, the stirring shaft 22 includes a front stirring shaft 221, a main stirring shaft 222, and a rear stirring shaft 223, which are connected in sequence. In some embodiments, the front stirring shaft 221 is inserted into the mounting hole and fixedly connected to the mounting frame 1, the front stirring shaft 221 has a first end and a second end that are relatively set, the first end is close to the connecting joint 21 relative to the second end, and the first end is inserted in the connecting joint 21; the stirring main shaft 222 is inserted into the mounting hole and fixedly set in the mounting frame 1, the stirring main shaft 222 includes a third end and a fourth end that are relatively set, the third end is close to the front stirring shaft 221 relative to the fourth end, and the third end is connected to the second end; the rear stirring shaft 223 is inserted into the mounting hole and fixedly connected to the mounting frame 1, the rear stirring shaft 223 has a fifth end and a sixth end that are relatively set, the fifth end is close to the stirring main shaft 222 relative to the sixth end, and the fifth end is connected to the fourth end.

In some embodiments, the cleaning component 3 includes a connecting member 31, a delivery pipe 32, a rotating pipe 33, a rotating seat 34, a sprayer 35 and a driving mechanism. The connecting member 31 is inserted into the discharge hole 2221 on the stirring shaft 22 and communicates with the inner cavity of the stirring shaft 22; the delivery pipe 32 is arranged on the stirring shaft 22 and connected to the connecting member 31; the rotating pipe 33 is arranged at one end of the delivery pipe 32 away from the stirring shaft 22 and communicates with the inner cavity of the delivery pipe 32; the rotating seat 34 is arranged on the rotating pipe 33 and communicates with the inner cavity of the rotating pipe 33; the sprayer 35 is arranged on the rotating seat 34 and communicates with the rotating seat 34; the driving mechanism is arranged in the delivery pipe 32, and the driving mechanism is connected to the rotating pipe 33, and is used to drive the rotating pipe 33 to rotate relative to the delivery pipe 32. When the rotating tube 33 is driven by the driving mechanism to rotate, the rotating seat 34 located outside the rotating tube 33 also rotates around the axial direction of the rotating tube 33. That is to say, the sprayer 35 located outside the rotating tube 33 can not only rotate around the axial direction of the stirring shaft 22, but also rotate around the axial direction of the rotating tube 33, so that the spraying direction and angle of the sprayer 35 can be finely adjusted, and the spraying path of the cleaning fluid can be flexibly changed, which effectively reduces the cleaning dead corners during the cleaning process and greatly improves the cleaning effect.

[0041] In some embodiments, an outer wall of the end of the connecting member 31 away from the stirring shaft 22 is provided with an external thread (not shown in the figure), and an inner wall of the end of the delivery pipe 32 close to the connecting member 31 is correspondingly provided with an internal thread (not shown in the figure).

When the cleaning fluid is delivered from the stirring shaft 22 to the delivery pipe 32, the cleaning fluid pushes the impeller 36, and the impeller 36 drives the input shaft of the reducer to rotate under the push of the cleaning fluid, thereby rotating the output shaft of the reducer, and the output shaft of the reducer drives the rotating tube 33 to rotate, so that the rotating tube 33 can drive the rotating seat 34 to rotate around the axial direction of the rotating tube 33.

[0043] In some embodiments, the delivery pipe 32 includes a first pipe body 321 and a second pipe body 322. The first pipe body 321 is arranged closer to the stirring shaft 22 relative to the second pipe body 322. The first pipe body 321 is detachably connected to the connecting member 31, and the second pipe body 322 is detachably connected to the first pipe body 321. When the impeller 36 or the reducer in the delivery pipe 32 fails, the first pipe body 321 and the second pipe body 322 can be quickly disassembled, so as to facilitate the maintenance and repair of the impeller 36 and the reducer in the delivery pipe 32.

[0044] In some embodiments, the cleaning assembly 3 further includes a fixed gear 37 and a moving gear 38, wherein the fixed gear 37 is disposed at one end of the delivery tube 32 close to the rotating tube 33, and the moving gear 38 is disposed in the rotating seat 34 and is meshed and connected with the fixed gear 37. It is understandable that when the rotating seat 34 rotates around the axial direction of the rotating tube 33, the rotating seat 34 can also rotate by meshing with the moving gear 38 and the fixed gear 37, thereby improving the comprehensiveness of the cleaning fluid sprayed outward by the sprayer 35, reducing the cleaning dead angle during the cleaning process, effectively improving the cleaning effect of the cleaning device 100, and improving the cleaning efficiency of the cleaning device 100.

[0045] In some embodiments, the cleaning component 3 includes a plurality of sprayers 35, which are evenly arranged circumferentially along the outer circumferential surface of the rotating seat 34 and are respectively connected to the inner cavity of the rotating seat 34, so that the cleaning fluid can be evenly sprayed to the outside through the sprayers 35, thereby improving the cleaning efficiency and enhancing the cleaning effect.

[0046] In some embodiments, the cleaning device 100 further includes a cleaning component 4, which is disposed on the mounting frame 1 and is used to remove waste residues and other substances on the inner wall of the evaporator cylinder 200.

In some embodiments, the cleaning assembly 4 includes a plurality of first cleaning mechanisms 41 and a plurality of second cleaning mechanisms 42.

The first cleaning mechanism 41 is used to remove waste residues with weaker adhesion on the inner wall of the evaporator cylinder 200, and the second cleaning mechanism 42 is used to remove waste residues with stronger adhesion on the inner wall of the evaporator cylinder 200. By using the first cleaning mechanism 41 and the second cleaning mechanism 42 at the same time, the first cleaning mechanism 41 can remove waste residues with weaker adhesion on the inner wall of the evaporator cylinder 200, and the second cleaning mechanism 42 can remove waste residues with stronger adhesion on the inner wall of the evaporator cylinder 200, so that the cleaning device 100 can clean different types of attachments on the inner wall of the evaporator cylinder 200, ensuring the reliability and comprehensiveness of the cleaning process.

[0055] In some embodiments, the rigid scraper 422 includes a first plate body 4223 and a second plate body 4224, the first plate body 4223 is arranged on the side of the second mounting plate 421 away from the stirring shaft 22, the second plate body 4224 is fixedly connected to the first plate body 4223, and forms an angle with the first plate body 4223, and the second plate body 4224 is inclined relative to the axial direction of the stirring shaft 22. In some embodiments, the angle of inclination of the second plate body 4224 relative to the axial direction of the stirring shaft 22 is 45° to 60°. In some embodiments, the connection between the first plate body 4223 and the second plate body 4224 is an arc transition, which is conducive to improving the structural strength, durability and working stability of the rigid scraper 422.

[0056] In the cleaning device 100 provided in the present application, when the stirring shaft 22 rotates, the sprayer 35 can not only rotate around the axial direction of the stirring shaft 22, but also can rotate around the axial direction of the rotating tube 33. At the same time, since the rotating seat 34 can rotate on its own, the sprayer 35 can also rotate around the axial direction of the rotating seat 34. The sprayer 35 continuously changes the spraying angle, so that the cleaning fluid can be evenly sprayed onto the inner wall of the evaporator cylinder 200, thereby expanding the cleaning range and improving the cleaning efficiency. The spraying direction and angle of the sprayer 35 can also be finely adjusted, and the spraying path of the cleaning fluid can be flexibly changed, thereby effectively reducing the cleaning dead corners during the cleaning process and greatly improving the cleaning effect of the cleaning device 100. In addition, a first cleaning mechanism 41 and a second cleaning mechanism 42 are used simultaneously. The first cleaning mechanism 41 can remove waste residues with weaker adhesion on the inner wall of the evaporator cylinder 200, and the second cleaning mechanism 42 can remove waste residues with stronger adhesion on the inner wall of the evaporator cylinder 200, so that the cleaning device 100 can clean different types of attachments on the inner wall of the evaporator cylinder 200, ensuring the reliability and comprehensiveness of the cleaning process.

[0057] In some embodiments, the evaporation device further includes a jacket heater 300, two support frames 400, two first seals 500 and two second seals 600. The jacket heater 300 is connected to the evaporator cylinder 200 for heating the evaporator cylinder 200; the two first seals 500 are respectively arranged at both ends of the evaporator cylinder 200 for sealing the jacket heater 300 and the evaporator cylinder 200; the two second seals 600 are respectively arranged at both ends of the evaporator cylinder 200 for sealing the front stirring shaft 221 and the first seal 500, and for sealing the rear stirring shaft 223 and the first seal 500; the two support frames 400 are arranged at both ends of the evaporator cylinder 200 for supporting the stirring shaft 22. The evaporation device provided by the present application does not need to use an additional steam cleaner or high-pressure cleaner that occupies a large space, and has a compact structure and saves space.
