Description

Technical Field

[0001] The utility model relates to the technical field of scrapers, and more specifically to a composite scraper. Background Art

[0002] The imperfect scraper structure of the impregnation filter machine causes the impregnation filter cake to leak during the conveying process. The main reasons are: 1. The original scraper is made of polyurethane and cannot be used in a high temperature environment for a long time; 2. The scraper does not have the advantage of wear resistance; 3. The impregnation filter cake itself has a specific viscosity, which easily causes the impregnation liquid to be not cleaned thoroughly. The leaked impregnation liquid is generally treated as solid waste, which will cause resource waste and environmental pollution.

[0003] Therefore, developing a composite scraper that has good scraping effect and can reduce the leakage of the impregnation liquid is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the utility model provides a composite scraper which has good scraping effect and can reduce the leakage of impregnation liquid.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A composite scraper, comprising:

[0007] Scraper,

[0008] A wear-resistant plate, the wear-resistant plate being arranged on the top of the scraper;

[0009] A gap adjustment component is connected to the wear-resistant plate and the conveyor belt, and is used to adjust the gap between the scraper and the conveyor belt.

[0010] The beneficial effect of adopting the above technical scheme is that in the utility model, the impregnated filter cake is scraped by a scraper, and the wear-resistant plate can support and buffer the scraper, so that the scraper can work uninterruptedly and improve the scraping efficiency; and the distance between the scraper and the conveyor belt can be adjusted by the gap adjustment component, so that the material can be scraped into the material trough intact, avoiding the leakage of the impregnated filter cake and reducing the waste of the impregnation liquid.

[0011] Preferably, the gap adjustment assembly includes: a fixed plate, a connecting plate and an adjusting bolt; the fixed plate is connected to the wear-resistant plate, the connecting plate is connected to both sides of the conveyor belt, one end of the adjusting bolt is fixedly connected to the connecting plate, and the other end passes through the fixed plate and is threadedly connected to a fixing nut. By adjusting the position of the fixing nut on the adjusting bolt, the gap between the scraper and the conveyor belt can be adjusted.

[0012] Preferably, a spring is sleeved on the outside of the adjusting bolt, and two ends of the spring are respectively in contact with the fixing plate and the connecting plate.

[0013] Preferably, the scraper is a stainless steel plate with a thickness of 1 mm. The stainless steel scraper can be used for a long time in a high temperature environment, which can improve the service life of the scraper and the scraping effect.

[0014] Preferably, the wear-resistant plate is a rubber plate with a thickness of 20 mm. The rubber plate can play a role of wear resistance and buffering, and can enable the scraper to work for a long time.

[0015] Preferably, the gap between the conveyor belt and the scraper is 2 mm.

[0016] It can be seen from the above technical solutions that, compared with the prior art, the utility model discloses a composite scraper, which has the following beneficial effects:

[0017] (1) In the utility model, the distance between the scraper and the conveyor belt is adjusted by the gap adjustment mechanism to form a gap fit, so that the material can be scraped into the storage tank intact, avoiding the waste of the impregnation liquid;

[0018] (2) The wear-resistant plate has a supporting and buffering function, which can make the scraper work uninterruptedly, so that the belt conveyor can achieve long-term stable operation and extend the service life of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS
