DETAILED DESCRIPTION
[0029] This embodiment is described in conjunction with the accompanying drawings when in use.
[0030] When cleaning the evaporator, the residue of the evaporator is on the inner wall. When using, first discharge the residual material in the evaporator, then fill the evaporator with water or other cleaning liquid, first soak and soften the residue on the inner wall of the evaporator, and then clean it. When cleaning, first cover the upper end of the evaporator with the positioning ring 1, and clamp it on the upper end of the evaporator through the annularly arranged clamping piece 13 on the lower end surface of the positioning ring 1. The positioning ring 1 is coaxially connected with a rotating shaft 2, and the lower end of the rotating shaft 2 extends into the evaporator. A protruding frame 3 is fixedly connected, the protruding frame 3 is perpendicular to the axis of the rotating shaft 2 and is arranged horizontally, the two ends of the protruding frame 3 are symmetrically extended toward the left and right ends respectively, and protruding rods 4 are respectively connected to the protruding ends of the protruding frame 3 in a horizontal sliding manner, and the outer side of each protruding rod 4 is respectively fixedly connected to a storage box 5, and the outer side of each storage box 5 is respectively fixedly connected to a scraper 7. The storage box 5 and the scraper 7 are respectively located at the left and right ends of the rotating shaft 2, and an opening is opened on one side surface of the storage box (5) facing the rotation direction. When in use, the storage box 5 and the scraper 7 work along the rotation direction of the rotating shaft 2.
[0031] The storage box 5 is a hollow structure, in which the hollow part is used to store the collected residue, and the storage box 5 is mainly used to collect floating objects on the upper surface of the liquid. When the storage box 5 rotates with the rotating shaft 2, the residue on the surface of the liquid will be guided to the inside of the storage box 5, and then a filter net 6 is provided on the opposite side of the storage box 5 and the opening. The residue is intercepted by the filter net 6, thereby achieving the effect of filtering the residue on the water surface. In the process of filtering the residue on the water surface, the opening on the storage box 5 is arranged obliquely inwardly, which not only allows the residue to enter conveniently, but also prevents the residue from coming out.
[0032] The scraper 7 is fixedly connected to the outside of the storage box 5 so that the scraper 7 is in direct contact with the inner side of the evaporator. The inner side of the scraper 7 is a hollow structure. A plurality of obliquely arranged scrapers 8 are fixedly connected to the contact parts between the outer side of the scraper 7 and the inner side of the evaporator. The scrapers 8 are arranged in parallel and extend obliquely upward in the rotation direction of the scraper 7. A slag stopper 12 is fixedly connected to the lower end of the outer side surface of the scraper 7 and the side surface opposite to the rotation direction. The slag stopper 12 is used to prevent the fallen residue from falling downward and detaching from the scraper 7. At the same time, it can scrape the fallen residue for collection and guidance, so that the scraped fallen residue enters the scraper 7 and is stored through the space inside the scraper 7.
[0033] When in use, it is often necessary to adjust the pressure of the scraper 7 on the inner side of the evaporator. A lifting member 9 is vertically slidably connected to the rotating shaft 2, and a threaded rod 11 is coaxially rotatably connected inside the rotating shaft 2. The lifting member 9 and the threaded rod 11 are threadedly matched, and the threaded rod 11 is rotated at the same time to adjust the height of the lifting member 9. The left and right ends of the lifting member 9 correspond to the position of the extension frame 3 and extend out of the rotating shaft 2 respectively. Support rods 10 are rotatably connected to the left and right extended ends of the lifting member 9 respectively, and the extended ends of each support rod 10 are rotatably connected to the corresponding extension rod 4 respectively. When the threaded rod 11 is rotated, the lifting member 9 will be synchronously lifted and lowered, so that the extension length of each extension rod 4 can be adjusted by the action of the support rod 10 to adapt to different evaporator sizes and adjust the pressure on the evaporator.
[0034] When in use, the rotation of the rotating shaft 2 is controlled by driving the limit ring 14 and the driving ring fixed on the upper end of the rotating shaft 2, and the rotating shaft 2 is coaxially connected to the positioning ring 1. In order to prevent the rotating shaft 2 from affecting the positioning ring 1 during rotation, the positioning ring 1 includes a plurality of positioning rods, and the lower end surface of each positioning rod is fixedly connected with a plurality of clamping parts 13 evenly distributed along the circumference of the rotating shaft 2. The clamping parts 13 are used to clamp on the evaporator to prevent the rotating shaft 2 from being eccentric during cleaning, thereby affecting the cleaning efficiency.
[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
