Description

Grid type grid dirt remover Technical Field The utility model relates to the field of dirt removers, in particular to a grid type grid dirt remover. Background Along with the acceleration of the urban process, the sewage treatment is also more and more important in urban construction, and the grating dirt remover is equipment for cleaning grating residues trapped by a grating out of the water surface by a mechanical method. The grid dirt separator is used in the front working procedure of sewage treatment, is used for intercepting and removing various solid particles, floaters and the like, so that the subsequent working procedure can be smoothly carried out, and is a key device for blocking and removing dirt in the treatment process of municipal sewage, industrial sewage and the like. At present, a rotary grid type sewage remover is mostly adopted, the rotary grid continuously rotates, the rake teeth intercept solid suspended matters in sewage, and when the intercepted matters are conveyed to the upper part of equipment, the rake teeth change the moving direction, and the solid sundries fall down automatically. The dirt on the rotary grating often falls incompletely, resulting in low dirt cleaning efficiency. When the residual dirt is large, the rotary grating is easy to be blocked. Particularly when sewage containing a large amount of fiber and hair substances is treated, the impurities are extremely easy to wind on the rake teeth and are difficult to clean by the existing self-cleaning and cleaning modes, so that the workload and frequency of maintenance and cleaning are increased. The abrasion of the rake teeth occurs after long-time use, the rake teeth need to be repaired and replaced, and the process is very time-consuming. Disclosure of utility model In order to improve the cleaning effect on substances such as fibers and hairs and facilitate maintenance of the dirt remover, the application provides a grid type grid dirt remover. The application provides a grid type grid dirt remover which adopts the following technical scheme: The grid type grid dirt remover comprises a frame, a fixed plate, a grid and a rotary cleaning assembly, wherein the frame is obliquely arranged, the fixed plate and the grid are both arranged on the frame along the oblique direction of the frame, the grid is attached to the fixed plate and positioned below the fixed plate, and the grid is used for allowing sewage to pass through and intercepting impurities in the sewage; The rotary cleaning assembly comprises a driving assembly, a transmission belt and a plurality of brushes, wherein the transmission belt and the brushes are positioned above the fixing plate and the grid grate, the transmission belt is in transmission connection with the frame, the driving assembly drives the transmission belt to transmit, the brushes are sequentially arranged on the transmission belt along the transmission direction of the transmission belt, and the brushes are used for cleaning impurities filtered by the grid grate when passing through the upper part of the grid grate; A sewage outlet is arranged above the frame, and the top end of the conveying belt is positioned right above the sewage outlet. Through adopting above-mentioned technical scheme, through the slope setting of frame and the reasonable layout of grating comb and gyration clearance subassembly for sewage can be through grating comb smoothly, and impurity is effectively intercepted, and gyration clearance subassembly can in time clear up impurity, guarantee the unobstructed of grating comb, the conveyer belt is with the brush to grating comb top clearance impurity, finally discharge impurity through the drain, the fibrous that the in-process brush can be better got rid of filtering, substances such as hair, the grating comb is fixed setting, and have not structures such as rake teeth, maintenance that can make things convenient for the dirt separator. Preferably, the grid net comb is detachably connected to the frame and the fixing plate, the bottom end of the frame is provided with a bottom frame, limit grooves are respectively formed in the bottom frame and the fixing plate, and two ends of the grid net comb are respectively abutted to the groove walls of the two limit grooves. Through adopting above-mentioned technical scheme, the detachable connection mode of grid net comb for when the grid net comb appears blockking up, damage or needs clearance, can dismantle and install convenient and fast, be convenient for maintain and change, the stability and the accuracy of grid net comb installation have been guaranteed in the setting of spacing groove. Preferably, the underframe, the fixing plate and the top surface of the grid mesh grate are positioned on the same plane. Through adopting above-mentioned technical scheme, such setting makes sewage when passing through the grating net comb, and rivers are more smooth and easy, can not lead to rivers unsmooth or impurity to pile up in
