Technical Field

[0001] The present application relates to the technical field of evaporator descaling, and more specifically, to an evaporator descaling scraper device. Background Art

[0002] An evaporator is a type of heat exchange device with phase change. It is a device that concentrates a solution or precipitates substances from a solution by heating. The evaporator is mainly composed of a heating chamber and an evaporation chamber. Evaporators are usually of two types: water surface evaporators and soil evaporators. They have characteristics such as multiple inputs and outputs, high temperature, high pressure, nonlinearity, large time lag and large inertia. They are widely used in concentration, purification and other processes. Their purpose is to make the low-pressure, low-temperature refrigerant liquid absorb the heat of the cooled medium during the evaporation process in a boiling state, thereby achieving the purpose of refrigeration.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] See also Figure 1-4A descaling scraper device for an evaporator includes a main body module 100 and two descaling scraper modules 200. The main body module 100 includes a substrate 110. An evaporator main body 120 is arranged on the top of the substrate 110. A protective component 130 is arranged on the top of the substrate 110 and located outside the evaporator main body 120. The two descaling scraper modules 200 are respectively arranged on both sides of the substrate 110. The descaling scraper module 200 includes a moving component 210 arranged on one side of the substrate 110. A telescopic scraper component 220 is arranged on the top of the moving component 210, and the telescopic scraper component 220 is located outside the protective component 130.

[0038] By setting the protective component 130, the evaporator body 120 can be protected, and at the same time, the protection of the evaporator body 120 can be released for descaling operations, and it is convenient for the user to observe the descaling situation. By setting the moving component 210, the telescopic scraper component 220 can be driven to move and adjust its position, so as to facilitate descaling at different positions of the evaporator body 120. By setting the telescopic scraper component 220, the height can be adjusted, so as to facilitate descaling areas at different heights of the evaporator body 120.

[0039] The protective assembly 130 includes two convex grooves 131, both of which are opened on the top of the base plate 110. The interiors of the two convex grooves 131 are slidably connected to convex blocks 132, and the tops of the two convex blocks 132 extend to the top of the base plate 110. A protective frame 133 is fixedly connected between the tops of the two convex blocks 132. The telescopic scraper assembly 220 includes a mounting groove 221 opened on the top of the moving assembly 210. The interior of the mounting groove 221 is fixedly connected to a first hydraulic cylinder 222, and the output end of the first hydraulic cylinder 222 extends to the outside of the mounting groove 221. The first hydraulic The output end of the cylinder 222 is fixedly connected to the hollow block 223. The telescopic scraper assembly 220 also includes a second hydraulic cylinder 224 fixedly connected to the inside of the hollow block 223, and the output end of the second hydraulic cylinder 224 extends to the outside of the hollow block 223. The output end of the second hydraulic cylinder 224 is fixedly connected to the rectangular block 225. The telescopic scraper assembly 220 also includes a drive motor 226 fixedly connected to one side of the rectangular block 225, and the output end of the drive motor 226 extends to the other side of the rectangular block 225. The output end of the drive motor 226 is fixedly connected to the scraper body 227.

[0040] By starting the first hydraulic cylinder 222, the hollow block 223 can be driven to rise and fall, thereby driving the scraper body 227 to rise and fall to adjust the height. By starting the second hydraulic cylinder 224, the rectangular block 225 can be driven to telescope and move, thereby driving the scraper body 227 to adjust the distance from the evaporator body 120. By starting the drive motor 226, the scraper body 227 can be driven to rotate, thereby descaling the evaporator body 120.

[0041] The moving assembly 210 includes two fixed blocks 211, both of which are fixedly connected to one side of the substrate 110. One end of the two fixed blocks 211 is fixedly connected to a mounting block 212. A screw rod 213 is rotatably connected between the two mounting blocks 212. The moving assembly 210 also includes a forward and reverse motor 214 fixedly connected to one side of one of the mounting blocks 212, and the output end of the forward and reverse motor 214 is fixedly connected to one end of the screw rod 213.

[0042] By starting the forward and reverse motor 214, the screw rod 213 can be driven to drive the moving block 215 to move, thereby driving the limiting plate 217 to slide inside the limiting slide groove 216, and then driving the scraper body 227 to move and adjust the position, thereby facilitating descaling at different positions of the evaporator body 120.

[0043] The implementation principle of the embodiment of the present application is as follows: when the evaporator main body 120 needs to be descaled, the protective frame 133 is first pushed to drive the two convex blocks 132 to slide inside the two convex grooves 131, so that the protective frame 133 can be disassembled, and then the forward and reverse motors 214 are started, and the forward and reverse motors 214 will drive the screw rod 213 to rotate, and the rotation of the screw rod 213 will drive the moving block 215 to move on the surface of the screw rod 213, and the movement of the moving block 215 will drive the limiting plate 217 to slide inside the limiting slide groove 216, so as to drive the telescopic scraper assembly 220 to move and adjust its position. When it moves to the evaporator main body 120, the forward and reverse motors 214 can be turned off, and then the second hydraulic cylinder 224 can be started to drive The rectangular block 225 is moved close to the evaporator body 120, and then the drive motor 226 is started. The drive motor 226 will drive the scraper body 227 to rotate, so that the rotating scraper body 227 can descale the evaporator body 120. At this time, the first hydraulic cylinder 222 is started, and the hollow block 223 returned by the first hydraulic cylinder 222 is raised, thereby driving the scraper body 227 to rise, and then the height can be raised to descale areas at different heights of the evaporator body 120. Then, the above steps are cyclically operated to comprehensively descale the evaporator body 120, and the descaling steps are easy for the user to observe, so that the progress of descaling is easy to understand, thereby ensuring the descaling effect and improving practicality.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
