Description
Technical Field
The utility model relates to the technical field of drag scrapers, in particular to a drag scraper of a drag scraper.
Background
The aeration sand basin is an important solid-liquid separation step in the water treatment process and is used for separating fine sand grains in water. The aeration sand basin is used for settling sand grains with the diameter of more than 0.2mm to the bottom of the basin under special flow state conditions. The chain plate type sand scraper scrapes sand grains deposited to the bottom of the pool into a mud discharging hopper arranged at the front end of the pool through front-to-back movement so as to achieve the effect of removing the sand grains.
In the existing municipal sewage, a chain plate type sand scraper is an important device in an aeration sand basin in a pretreatment stage, and consists of a driving device, a chain and a scraping plate. And circulating in the aeration sand basin. The lower scraping plate moves from back to front and clings to the bottom of the pool. The deposited sand grains can be effectively scraped to the front mud bucket. Since the deposited sand is generally relatively hard, and the squeegee runs against the floor of the tank. The scraping plate can be damaged under the condition that the scraping plate is seriously worn due to friction between the scraping plate and the pool bottom and sand grains in the running process.
In view of the foregoing, in order to overcome the defects in the prior art, a scraper of a scraper plate type scraper is particularly needed to solve the defects in the prior art.
Disclosure of Invention
In view of the problems existing in the prior art, the utility model aims to provide the scraper of the chain scraper type sand scraper, which is novel in design, good in wear resistance and excellent in practicality.
In order to achieve the above object, the present utility model adopts the following technical scheme: a drag chain scraper comprising: install the scraper blade body on the scraper chain, the antifriction plate is installed to the bottom of scraper blade body, the antifriction plate is arranged along the length direction of scraper blade body, the through-hole has all been seted up to the correspondence with the bottom of scraper blade body on the antifriction plate, and fixing bolt passes through the through-hole and connects antifriction plate and scraper blade body fixedly.
As a preferable mode of the utility model, the wear-resistant plate is in a long strip shape.
As a preferred embodiment of the present utility model, the wear plate has a width of 51mm.
As a preferred embodiment of the present utility model, the wear plate has a thickness of 13mm.
In a preferred embodiment of the present utility model, the wear plate is made of polyethylene.
As a preferable scheme of the utility model, a countersunk groove is formed below the through hole of the wear-resisting plate, and the bolt head of the fixing bolt is arranged in the countersunk groove.
By adopting the technical scheme, the utility model has the following beneficial effects:
the utility model has simple structure and reasonable design, the added wear-resistant block is made of ultra-high molecular polyethylene and has good wear resistance, the wear-resistant block is arranged at the bottom of the scraper, and a protective layer is directly formed on the scraper and the concrete at the bottom, so that the wear-resistant problem of the scraper can be effectively prevented, the long-term continuous operation of the mud scraper is facilitated, and the practicability is excellent.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Example 1
As shown in fig. 1 to 4, a specific embodiment of a scraper for a drag type scraper according to the present utility model includes: install scraper blade body 3 on the scraper chain, wear-resisting plate 1 is installed to the bottom of scraper blade body 3, and wear-resisting plate 1 arranges along the length direction of scraper blade body 3, arranges quantity and follows scraper blade length variation, and through-hole has all been seted up to the bottom of all correspondence of wear-resisting plate 1 and scraper blade body 3 on the fixing bolt 2 is connected wear-resisting plate 1 and scraper blade body 3 through the through-hole fixedly, can conveniently change and install wear-resisting plate 1 through fixing bolt 2.
The wear-resisting plate 1 is in a strip shape, the width is 51mm, the thickness is 13mm, and the material of the wear-resisting plate 1 is polyethylene, preferably ultrahigh molecular polyethylene.
Countersunk grooves are formed below the through holes of the wear-resisting plate 1, and bolt heads of the fixing bolts 2 are arranged in the countersunk grooves to prevent the bolt heads from being worn.
The working principle of the utility model is as follows: according to the utility model, the novel scraper of the sand scraper is formed by mounting the wear-resisting plate 1 on the scraper body 3, the added wear-resisting plate 1 is made of ultra-high molecular polyethylene and has good wear resistance, and a protective layer is formed between the scraper and the bottom concrete, so that the problem of abrasion of the scraper can be effectively solved.
