[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-2 , the embodiments of the present utility model include:

[0024] A stirring and cleaning mechanism for a single-effect evaporator comprises an evaporator 1, an evaporation chamber 2, an evaporation auger assembly 3, and a cleaning scraper mechanism 4.

[0025] An evaporation chamber is provided in the evaporator. The evaporation auger assembly can be rotatably arranged in the evaporation chamber under the action of a rotary drive mechanism. The cleaning scraper mechanism is connected to the evaporation auger assembly to scrape and clean the inner wall of the evaporation chamber.

[0026] The evaporation auger assembly 3 includes an auger shaft 31, a reinforcing connecting rod 32, and a spiral feeding blade 33. The reinforcing connecting rod is arranged on the auger shaft, the spiral feeding blade is arranged on the reinforcing connecting rod, and the outer end of the reinforcing connecting rod is flush with or protrudes from the outer edge of the spiral feeding blade.

[0027] Multiple groups of cleaning scraper mechanisms are spirally arranged in sequence from top to bottom along the spiral feed blades on the outside of the auger shaft. Each cleaning scraper mechanism is arranged axially (vertically) along the auger shaft, and the angle between adjacent cleaning scraper mechanisms is less than or equal to 120°. Each cleaning scraper mechanism is respectively connected to two adjacent reinforcing connecting rods located in the same vertical plane, and the length of the cleaning scraper mechanism is greater than the spacing between the two reinforcing connecting rods connected to it. In this way, when the evaporation auger assembly rotates, the cleaning areas of adjacent cleaning scraper mechanisms can be connected or overlapped with each other, so that the cleaning range / area after all the cleaning scraper mechanisms are combined can cover the entire evaporation chamber or the working part of the evaporation chamber where there is a problem of plate formation and scaling due to contact with the heat source, thereby improving the cleaning effect and efficiency.

[0028] In this embodiment, three adjacent cleaning scraper mechanisms can form a cleaning scraper group. The three cleaning scraper mechanisms in a cleaning scraper group are staggered in height, and the angle between two adjacent cleaning scraper mechanisms is 120°. There are four cleaning scraper groups arranged in sequence from top to bottom on an evaporating auger assembly.

[0029] Further preferably, the reinforcing connecting rod and the spiral feeding blade are an integrated structure, or are connected by welding.

[0030] The cleaning scraper mechanism 4 includes a cleaning installation platform 41, a platform installation connector 42, a platform installation connection groove, multiple scraper assemblies 43, a tool holder threaded connecting rod 44, a limiting fixing nut 45, and a connecting thread groove.

[0031] The platform mounting connecting groove is arranged in the outer end of the reinforcing connecting rod, one end of the platform mounting connecting piece is connected to the cleaning mounting platform, and the other end is connected to the platform mounting connecting groove to fix the cleaning mounting platform on the reinforcing connecting rod. A plurality of connecting thread grooves are arranged on the cleaning mounting platform, the outer end of the tool holder threaded connecting rod is connected to the scraper assembly, and the other end is threadedly connected to the connecting thread groove. The tool holder threaded connecting rod between the cleaning mounting platform and the scraper assembly is movably provided with a contour gasket 46. The telescopic distance of the scraper assembly can be adjusted by adjusting the depth (degree) of the connection between the tool holder threaded connecting rod and the connecting thread groove and the thickness of the contour gasket. The installation angle of each scraper assembly can also be adjusted independently, so that the scraper can be tilted or horizontally arranged on the cleaning mounting platform, so that the scraper assembly can not only be close to the inner wall of the evaporation chamber, but also the coverage (working) range of each scraper assembly can be connected or overlapped, thereby preventing cleaning dead corners due to gaps between the scrapers and improving the cleaning quality.

[0032] The limit fixing nut is threadedly connected to the tool holder threaded connecting rod on the inner side of the cleaning installation platform to limit and lock the movement of the tool holder threaded connecting rod. After the tool holder threaded connecting rod is adjusted to the position, the limit fixing nut can be tightened until it is close to the cleaning installation platform to prevent the tool holder threaded connecting rod from loosening or even falling off during rotation, thereby improving the stability of the connection and ensuring the cleaning effect.

[0033] Further preferably, the platform mounting connector is a connecting bolt, and the connecting bolt is plugged into or interference-connected with the platform mounting connecting groove.

[0034] Further preferably, the platform installation connecting member is a bolt, and the bolt is threadedly connected to the platform installation connecting groove and the cleaning installation platform.

[0035] Further preferably, the rubber scrapers in the scraper assemblies located at both ends of the cleaning installation platform protrude from the end surfaces of the cleaning installation platform.

[0036] The scraper assembly includes a rubber scraper 431, a blade holder 432, a fixing bolt 433, and a fixing nut. The rubber scraper is movably arranged in the blade holder. The outer side and left and right sides of the rubber scraper protrude from the blade holder, and the scraping areas of adjacent rubber scrapers are connected to or overlap with each other. The rubber scraper has a certain flexibility and can adapt to different cleaning environments. The cooperation of multiple groups of rubber scrapers can perform adaptive scraping operations more accurately and independently. The fixing bolt passes through the blade holder and the rubber scraper and is connected to the fixing nut to fix the rubber scraper on the blade holder, which is also convenient for later maintenance and replacement.

[0037] Further preferably, the tool holder and the tool holder threaded connecting rod are an integrated structure.

[0038] Further preferably, the knife holder is made of stainless steel.

[0039] The beneficial effect of the stirring and cleaning mechanism for a single-effect evaporator of the utility model is that the dirt on the inner wall of the evaporation chamber is scraped off by cooperating with the evaporation auger assembly and the cleaning scraper mechanism, thereby effectively alleviating the problem of compaction of the inner wall of the chamber, further improving the efficiency of feeding and stirring, and extending the practical life of the entire product.
