Description

Sludge storage bin material taking device

Technical Field

The utility model relates to a sludge treatment technical field specifically is a mud feed bin extracting device.

Background

The sludge treatment and disposal method mainly comprises landfill, incineration and land utilization in various forms. Due to different specific conditions of various countries, the selected methods are emphasized, the general trend is that the landfill method is gradually reduced, and the incineration and land utilization are gradually improved. The burning method is regarded by various countries because of its large decrement ratio and the ability to avoid secondary pollution.

The treatment process of sludge incineration comprises the following steps: wet sludge → pressure filtration dehydration → drying → storage in a bunker → incineration → landfill of residue. One important link is that sludge with 10-13% of water content after drying needs to be stored in a storage bin and then quantitatively fed into an incinerator for incineration through a feeder. However, the sludge also contains a certain amount of water and has a high viscosity. Therefore, the sludge is often not stuck on the wall surface or is formed into blocks to form an arch when being stored in the storage bin, so that the sludge cannot fall and be taken out. At present, the conventional method is that the stock bin is made into an inverted cone with a small upper part and a large lower part, a row of spirals are arranged below the stock bin, but the inclined wall surface still has residues, and even if vibration is increased by using an air cannon or a mechanical rapping device, the stock bin has higher requirements on the structure, the material and the layout, and is high in cost and cannot vibrate under the condition that the stock bin is usually bonded. Foreign countries have circular sludge bins which adopt planetary spiral material taking, although the discharging effect is very high, the cost is too high, generally foreign enterprises can accept the circular sludge bins, and domestic sludge treatment enterprises can not accept the circular sludge bins.

Disclosure of Invention

In order to solve present mud and bond easily when the feed bin ejection of compact and remain, the caking forms the arch even, influences ejection of compact effect, the high problem of foreign import equipment cost, the utility model provides a mud feed bin extracting device, it can avoid the material to remain, prevents that the caking from forming the arch, guarantees ejection of compact effect, and equipment cost is low simultaneously.

The technical scheme is as follows: the utility model provides a mud feed bin extracting device, its includes the feed bin, the discharge gate has been seted up to the feed bin bottom, discharge gate department installs ejection of compact screw mechanism, a serial communication port, ejection of compact screw mechanism includes two intervals and the spiral ejection of compact machine of symmetrical arrangement side by side, two install rabbling mechanism between the spiral ejection of compact machine, the rabbling mechanism including install in the carousel of feed bin bottom, the feed bin is the cylinder, two at least scraper blades are installed to the carousel outer peripheral face, the carousel is through running through driving motor is connected to the transmission shaft of feed bin bottom.

It is further characterized in that the scraper is an elastic scraper;

the elastic scraper is formed by superposing at least two vertically arranged spring steel plates;

a connecting sleeve is fixed at the end part of the scraper, and the connecting sleeve is connected with the turntable through a stay rope to enable the scraper to be bent;

a sawtooth block is fixed on the connecting sleeve;

a gap which is not more than 1cm is reserved between the sawtooth block and the inner wall of the storage bin;

the scrapers are arranged in a staggered manner from top to bottom;

the root of the spring steel plate is fixed by at least two hoops;

the material loosening roller is positioned above the discharge port, the material loosening roller is arranged in the storage bin, sharp teeth are arranged on the outer surface of the material loosening roller, two ends of the material loosening roller penetrate through the inner wall of the storage bin, and one end of the material loosening roller is connected with a material loosening motor;

the outer wall of the bottom of the storage bin is fixedly provided with a bearing seat matched with the transmission shaft, and the storage bin is supported and fixed on the rectangular frame support.

After the utility model is adopted, after the sludge enters the material bin, the sludge enters the spiral discharging machine from the discharge port at the bottom for discharging, and because the stirring mechanism is arranged, the turntable rotates to drive the scraper blade to rotate, thereby stirring the sludge, preventing the sludge from caking into an arch shape, and the scraper blade at the lower part can also play a scraping role, scraping the sludge at the bottom of the material bin and moving to the discharge port along with the scraper blade, thereby ensuring the discharging effect, and having simple and compact structure and low cost; further, the scraper blade adopts the elasticity scraper blade, can alleviate the resistance through warping when the resistance is big, so be difficult to block up, utilize the superpose of the spring steel sheet of multi-disc vertical layout to form the intensity of guaranteeing the scraper blade, the little clearance of sawtooth block cooperation and feed bin inner wall can let on the feed bin inner wall basically also can be scraped down, guarantees to stir and scrapes the material no dead angle, lets mud not bridge.
