Pore plate grating system

Abstract

The invention relates to a pore plate grating system which comprises a rack for supporting and two groups of guide grooves for guiding rotation of a pore plate chain, wherein the two groups of guide grooves are oppositely arranged; a main shaft which is rotatably mounted on the rack, wherein the main shaft is provided with a chain wheel; the pore plate chain which comprises a plurality of pore plates and a plurality of rotating shafts, the two ends of each pore plate are rotatably connected to the two adjacent rotating shafts respectively, the pore plates jointly define an annular structure, and the two ends of each rotating shaft are movably restrained in the guide grooves respectively; a plurality of sealing parts are arranged at the two ends of the pore plate chain respectively, each sealing part is provided with a first matching surface, at least one side of each guide groove is provided with a second matching surface, and the first matching surfaces and the second matching surfaces are mutually staggered and matched to form dynamic sealing; according to the pore plate grating system, the sealing parts are arranged so that sewage can flow out of the pore plate chain only through the filtering holes of the pore plate, the capability of intercepting grating slag can be ensured, and the sewage treatment effect can be improved.

Description

Technical field [0001] The present invention relates to the field of sewage treatment, and more particularly to a hole plate grid system. Background technique [0002] The well plate grille is very common in sewage treatment, usually with fine grills and ultra-fine grids, in practical applications, the orifice grid is separated from the size of different sizes of impurity garbage by the size of the filter hole, mainly The sewage is pretreated to provide convenience for subsequent processing; the intravation plate grid is one of the hole plate grid, which is a pretreatment device for the precision and efficient removal of hair and fine fibers in sewage in sewage treatment plants. It has strong interception capacity, high removal rate, wide application in the field of sewage treatment. [0003] The inner into the fluorescence plate grille typically includes a rack, a hole plate system (or a mesh system), a rinsing system (or a sprinkler system), a slag system, etc., wherein the o...

Problems solved by technology

[0005] The first aspect of the present invention is to solve the problem existing in the prior art that there is a large gap between the two ends of the orifice chain and the frame, which leads to serious water leakage and slag leakage and reduces the interception accuracy, and provides a The orifice grid system can effectively prevent sewage, especially grid slag, from leaking from the gap between the orifice chain and the frame, so that the sewage can only flow from one side of the orifice chain to the other side through the filter holes of the orifice, thus It can ensure the ability to intercept the grid slag, which is beneficial to improve the removal rate of the grid slag, and is more conducive to improving the sewage treatment effect; the main idea is:
