Description

Scraper Conveyor Current Limiting Adjustment Device in Feed Processing Equipment

technical field

The utility model belongs to the technical field of scraper conveyors in feed processing equipment, in particular to a current-limiting adjustment device for scraper conveyors in feed processing equipment.

Background technique

The scraper conveyor is mainly used as an ideal equipment for conveying pellets and powders in feed, grain, oil, chemical and other industries. According to the shape of the bottom of the scraper, it is mainly divided into a round bottom scraper and a flat bottom scraper. TGSU series round bottom scraper has high conveying efficiency, safe and reliable operation, and is equipped with anti-blocking alarm device, easy maintenance, low noise, good self-cleaning and no residue. TGSS series flat-bottomed scraper has the characteristics of simple structure, small size, strong sealing, convenient installation and maintenance. The scraper has the characteristics of large conveying capacity, less damage when conveying materials, low noise during operation, and high transmission efficiency. It has multi-point feeding and discharging. , the process layout is quite flexible, and the conveying distance is long. It is an ideal and energy-saving conveying equipment.

At present, in the operation of the scraper conveyor, after the operating speed is selected, in actual work, it is usually necessary to adjust the conveying output of the scraper according to the actual working output of the on-line equipment and the off-line equipment of the scraper conveyor, usually at A current limiting adjustment device is installed at the feed port of the scraper to adjust the feeding height of the scraped material at the feed port of the scraper to achieve the purpose of controlling the conveying output. The gate plate and the housing of the current-limiting adjustment device must be able to move freely up and down and be accurately fixed at any height, and the support between the gate plate and the housing must have high strength. When the powder is fed, the powder falling into the feed port from a high place has a great impact on the scraper. The dust of the material is often discharged between the conventional gate and the shell. In severe cases, the entire plant is covered by dust. Sometimes a suction port is added to the feed port of the scraper to reduce dust with a fan and a pulse dust collector, but because the air volume for short-term processing is very large, it is impossible to completely eliminate the dust. Not only is the working environment for workers very poor, but dust explosions are easily produced when encountering sparks, causing major safety accidents, which must be thoroughly resolved.

The height of the board.

The width of the gate installation opening 1 is consistent with the width of the scraper chain, and the width of the gate support frame matches the width of the gate installation opening, which is convenient for the adjustment of the gate. There is a ram guide plate inside the ram support frame, the two ends of the ram guide plate are connected with the ram support frame, and there is a ram guide gap between the ram guide plate and the ram support frame.

The ram guide plate is a right-angle bending part, the vertical surface of the ram guide plate and the inner travel ram guide gap of the ram support frame, and the ram guide gap=2mm.

The utility model has the advantages: the adjusting gate of the utility model can be adjusted up and down according to different current limiting output, and can be accurately positioned at any height of the material layer. The sealing cover can completely seal the adjusting gate inside, completely preventing the leakage of dust. The utility model has the advantages of simple and reliable structure, convenient manufacture and installation, and reliable operation. It is easy to use, stable in operation quality, can meet the needs of different types of scraper machines, and can save the power consumption of adding a pulse dust collector fan for dust removal, thereby reducing the cost of feed production.
