Abstract
An installation structure of a sludge thickener comprises a circular pool body and a sludge thickener body installed inside the circular pool body. A working bridge is arranged at the top end of the circular pool body. A vertical worm reducing gear is installed in the center of the working bridge. The reducing gear is connected with a motor through a belt wheel. A transmission shaft of the reducing gear is connected with a stirring shaft. The upper end of the stirring shaft is sleeved with a flow guiding cylinder. Stirring blades are arranged on the stirring shaft inside the flow guiding cylinder. Four U-shaped wall scraping pipelines communicated with the stirring shaft are arranged at the middle section of the stirring shaft around the circle center of the stirring shaft. Upward-vertical grid bars are distributed at the upper end of the bottom pipeline of the U-shaped wall scraping pipelines at intervals. The lower end of the bottom pipeline is connected with a scraper. The upper pipeline of the U-shaped wall scraping pipelines is provided with a pull rod to be fixed to the stirring shaft in a tensioning mode. A settling pond sludge discharging pipe and an oil-water separator sludge discharging pipe are connected to the flow guiding cylinder in the tangent direction. A supernate outlet pipe is formed in the portion, close to the top end, of the circular pool body. A sludge discharging pipe is formed in the bottom end of the circular pool body. The structure is reasonable, the sludge discharging efficiency is high, the stirring blades are arranged inside the flow guiding cylinder, the sludge block drying rate is greatly decreased, and the thickening efficiency is improved.
Description
Technical field
The present invention relates to sewage treatment area, particularly relate to sludge concentrator.
Background technology
Cutting-type sludge concentrator, be a kind of center driving continuously or the concentrated and clarifying equipment of service intermittent.It mainly for sludge concentration 1%, or concentration is lower than the mud of 1%, improves its solid content, namely sludge concentration, flows out concentration more than 3%, be convenient to follow-up mechanical dehydration after cutting-type sludge concentrator is concentrated, improves the working efficiency of mechanical dehydration.
But, in the process of sludge concentrator thickened sludge, have partial sludge float, easily lump under sun exposure and hot conditions, form the solid block layer of thicker mud at the liquid level of concentration basin.The cutting-type sludge concentrator of prior art, when the solid agllutination of mud become bulk and sinking watching time, grizzly bar can not smash the solid block of mud by stirring fully, the sludge bulking of bulk is caused to sink to the string of deposits, then spoil disposal pipeline is brought into, easy blocking pipe, seriously reduces work quality and the working efficiency of thickner, also can affect desliming effect when the desliming of lower one treatment process simultaneously.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide following technical scheme: a kind of sludge concentrator mounting structure, comprise circular pond body, be installed on the sludge concentrator in the body of circular pond, circular body top, pond is provided with service bridge, service bridge center is provided with vertical worm reduction gear, step-down gear connects motor by belt pulley, speed reducer driving shaft connects stir shaft, it is characterized in that stir shaft upper end is sheathed in guide shell, the stir shaft being positioned at guide shell is provided with agitating vane, stir shaft stage casing is provided with 4 single u-shaped be communicated with stir shaft and scrapes wall pipeline around the stir shaft center of circle, the grizzly bar that U-shaped bottom pipe upper end of scraping wall pipeline is intervally arranged straight up, the lower end of bottom pipe is connected with cleaning shoe, U-shaped upper pipe of scraping wall pipeline is provided with pull bar and stir shaft is strained and fixed, described guide shell is tangentially connected with settling pond shore pipe and water-and-oil separator shore pipe, circular Ti Jin top, pond offers supernatant liquor rising pipe, circular body bottom, pond offers shore pipe.
As preferably, be provided with pyramid type groove bottom the body of circular pond, be provided with bearing in pyramid type groove, stir shaft end is inserted in bearing, and shore pipe is communicated with pyramid type groove.
As preferably, shore pipe is communicated with pre-buried penstock.
As preferably, circular pond body is provided with the slope that obliquity is 5 degree.
As preferably, circular pond body is just provided with water outlet weir plate to supernatant liquor water outlet pipe part.
As preferably, the junction of circular pond body and service bridge is provided with pre-embedded steel slab.
Beneficial effect of the present invention: the present invention is rational in infrastructure, spoil disposal efficiency is high, arranges agitating vane in guide shell, greatly reduces the dry and hard rate of clod, improves thickening efficiency.
