[0002] A spiral classifier is a commonly used device in the beneficiation field. It conducts mechanical classification based on the principle that solid particles have different precipitation speeds in a liquid due to different specific gravities. It is mainly used for classifying and filtering the powdered materials ground in a mill during the beneficiation process. When the spiral classifier is working, it is easy for the powdered materials to adhere to the blades, which affects the classification effect and increases costs. Therefore, a scraping assembly is needed to scrape off the powdered materials adhering to the blades.

[0003] The Chinese patent discloses an automatic scraping device for a spiral classifier (publication number CN217527809U). This patented technology uses a liquid level gauge and a controller to cooperate to control the start and stop of the driving motor, automatically control the height of the scraping plate for scraping, saving time and effort, improving the classification efficiency of the spiral classifier, enhancing the classification effect, and greatly reducing the economic cost.

[0004] However, most of the existing scraping methods for spiral classifiers are scraping from top to bottom. Since there are rotating shafts between the blades of the spiral classifier, this will affect the scraping work of the scraping plate on its blades, and it is also impossible to make the scraping plate in close contact with the blades, affecting the scraping effect. As in the above comparative document, it adopts the up-and-down scraping method. In actual application, there are rotating shafts in the blades of the spiral classifier, which will affect its scraping work. Therefore, those skilled in the art have provided an automatic scraping assembly for a spiral classifier to solve the problems raised in the above background technique. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for an automatic scraping component of a spiral classifier: including: a cleaning frame 1 and a mounting frame 11 provided on the lower surface of the cleaning frame 1. A moving groove is opened at the middle position of the lower surface of the cleaning frame 1. A moving plate 31 is slidably installed inside the moving groove. A connecting block 3 is installed on the lower surface of the moving plate 31. A positioning rod 32 is provided through the upper surface of the moving plate 31. The lower surface of the connecting block 3 is connected to a mounting plate 2. Connecting plates 21 are installed at both end faces of the lower surface of the mounting plate 2. One side of the connecting plate 21 is provided with a connecting rod 23 through it. One end of the connecting rod 23 is connected to a scraping plate 22. This setting uses the scraping plate 22 to scrape the blades of the spiral classifier, and the spring 233 can make the scraping plate 22 closely fit the blades to achieve efficient scraping work on the blades, with good practicability.

[0022] As Figure 1 and Figure 3 shown, limiting holes 12 are symmetrically opened on the upper surface of the cleaning frame 1. The upper end of the positioning rod 32 penetrates inside the limiting holes 12. An electric telescopic rod 34 is also provided inside the moving plate 31. The lower end of the positioning rod 32 is connected to a positioning disc 33 inside the moving plate 31. The telescopic end of the electric telescopic rod 34 is connected to the lower surface of the positioning disc 33. This setting uses the operation of the electric telescopic rod 34 to make the upper end of the positioning rod 32 penetrate the limiting holes 12, and thus the purpose of positioning and installing the moving plate 31 can be achieved.

[0023] As Figure 3As shown, the connecting block 3 has the same length as the moving plate 31, and the connecting block 3 and the moving plate 31 are arranged in a "T" shape. This setting enables the moving plate 31 connected by the connecting block 3 to slide inside the moving groove, so as to adjust the position of the scraping plate 22 to scrape the blades of the spiral classifier.

[0024] As Figure 4 shown, four connecting rods 23 are symmetrically arranged on one side of the connecting plate 21. A fixing groove 231 is formed inside the connecting plate 21. A spring 233 is arranged inside the fixing groove 231. One end of the connecting rod 23 is connected with a limiting disc 232 inside the fixing groove 231. One end of the spring 233 is fixed at the inner end of the fixing groove 231, and the other end of the spring 233 is fixed on one side of the limiting disc 232. This setting enables the scraping plate 22 to be in close contact with the blades of the spiral classifier by using the spring 233, so that the scraping plate 22 can better scrape the blades of the spiral classifier.

[0025] The working principle of the present utility model is as follows: When the automatic scraping assembly of the spiral classifier of the present utility model is in use, first, the scraping plate 22 is installed on the lower surface of the cleaning frame 1. During installation, the moving plate 31 connected by the connecting block 3 can slide inside the moving groove formed on the lower surface of the cleaning frame 1. After sliding, the positioning rod 32 will penetrate through the inside of the limiting hole 12 due to the work of the electric telescopic rod 34 inside the moving plate 31, so as to limit the moving plate 31. After fixation, the cleaning frame 1 can be installed on the frame of the spiral classifier and fixed through the mounting frame 11. At the same time, the two connecting plates 21 will be arranged outside the blades of the spiral classifier, and the scraping plate 22 will also be in contact with the surface of the blades of the spiral classifier. A spring 233 is arranged in the fixing groove 231 formed inside the connecting plate 21. In this way, the spring 233 enables one side of the scraping plate 22 to be in close contact with the blades of the spiral classifier, so that when the blades of the spiral classifier rotate, the scraping plate 22 can scrape the powder on the blades, and the practicability is good.

[0026] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
