Scraper mechanism of chain type scraper

Abstract

A scraper mechanism of a chain type scraper comprises conveying chains, scraper assembling components are arranged on the conveying chains, scrapers are arranged between the conveying chains arranged oppositely through the scraper assembling components, the scrapers are divided into two specifications, and the scrapers comprise rectangular scrapers and special-shaped scrapers. The special-shaped scraping plate is provided with serrated surfaces which are arranged in an array manner in the direction facing the bottom plate; and the special-shaped tube plates and the rectangular scrapers are alternately arranged between the conveying chains. The problem that in the prior art, powder slurry is continuously accumulated on the bottom plate, and consequently a conveying chain is twined is solved. In other words, the sharp front end face of the special-shaped scraping plate faces the direction of the bottom plate, and the situation that the height of the upper portion of the special-shaped scraping plate is continuously increased due to accumulated materials is avoided. And particularly, the equipment is simple in overall structure, low in arrangement or modification cost and higher in popularization value.

Description

Technical Field

[0001] The utility model relates to the field of conveyor mechanisms, in particular to a chain-type scraper mechanism. Background Art

[0002] In the process of cement material production, the scraper conveyor is the main equipment for conveying materials. However, as the materials are usually wet powder or slurry, it is very easy for the bottom plate of the scraper conveyor to stick to the materials. During continuous operation, if the bottom plate is not scraped cleanly, the scraper will continue to move upward, and the chain at the bottom will also rise. It is common that the chain rise is not discovered in time, resulting in the entanglement of the upper and lower chains, causing the scraper conveyor to jump and stop, affecting production. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a chain scraper scraper mechanism with a simple structure, which changes the existing scraper form and specific arrangement structure, avoids the continuous rise of the lower chain caused by insufficient scraping of the bottom plate, and thus causes the scraper to stop.

[0004] The equipment includes a conveyor chain, and the conveyor chain is the double-track conveyor chain of the scraper conveyor in the prior art;

[0005] A scraper assembly component is provided on the conveying chain, and scrapers are provided between the conveying chains arranged opposite to each other through the scraper assembly component;

[0006] The scraper has two specifications, including a rectangular scraper and a special-shaped scraper. The special-shaped scraper has a serrated surface arranged in an array facing the bottom plate. The special-shaped tube plate and the rectangular scraper are alternately arranged between the conveying chains.

[0007] The effect achieved in this way is that the serrated surface of the special-shaped scraper acts as a countermeasure to the powder slurry and the scaling of the powder slurry deposited on the corresponding bottom plate, scooping them up and pushing them away. The part that overflows the special-shaped scraper is continued to be pushed away by the rectangular scraper at the rear section, preventing the material on the bottom plate from continuing to float up.

[0008] The beneficial effect of the utility model is that the utility model solves the problem in the prior art that the powder slurry is continuously accumulated on the bottom plate, which causes the conveying chain to be entangled. The slurry on the bottom plate is continuously scraped off, that is, the sharp front end of the special-shaped scraper faces the bottom plate to prevent the height above it from continuously rising due to the accumulated materials. In particular, the overall structure of the equipment is simple, the layout or modification cost is low, and it has more promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0014] Reference Figure 1 , Figure 2 The scraper mechanism of a chain scraper conveyor described in the utility model comprises a conveying chain 1, and the conveying chain 1 is the double-track conveying chain 1 of the scraper conveyor in the prior art;

[0015] A scraper assembly component 2 is provided on the conveying chain 1, and scrapers are provided between the conveying chains 1 arranged opposite to each other through the scraper assembly component 2;

[0016] The scrapers have two specifications in total, including a rectangular scraper 4 and a special-shaped scraper 3. The special-shaped scraper 3 has a serrated surface arranged in an array facing the bottom plate; the special-shaped tube plate and the rectangular scraper 4 are alternately arranged between the conveyor chains 1.

[0017] The effect achieved in this way is that the serrated surface of the special-shaped scraper 3 faces the powder slurry and the scale of the powder slurry deposited on the corresponding bottom plate, scoops them up and pushes them away, and the part that overflows the special-shaped scraper 3 is continued to be pushed away by the rectangular scraper 4 at its rear section, preventing the material on the bottom plate from continuing to float up.

[0018] Furthermore, the rectangular scrapers are arranged in a 41:1 interval array.

[0019] Furthermore, the serrated surface on the special-shaped scraper 3 is a slope, and the slope direction thereof gradually increases from the direction facing the bottom plate to the rear.

[0020] The effect achieved thereby is better removal of the coal slime.

[0021] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
