Description

TECHNICAL FIELD

[0001] The utility model relates to rain and sewage treatment technical field, concretely is a kind of filter and processing equipment of rain and sewage diversion. BACKGROUND

[0002] Rain and sewage diversion is a drainage system, which refers to the separation of rainwater and sewage, each using a pipeline for delivery, discharge or subsequent treatment of sewage. Rainwater pollution is light, and after diversion, it can be directly discharged into urban rivers, and after natural sedimentation, it can be used as natural landscape water or municipal water supply for road spraying. Therefore, rainwater can improve the use efficiency of surface water after purification and buffering into rivers. At the same time, sewage is discharged into the sewage pipe network and treated by the sewage treatment plant to realize sewage recycling. Rain and sewage diversion can speed up the sewage collection rate, improve the sewage treatment rate, avoid pollution of rivers and groundwater by sewage, significantly improve the urban water environment, and reduce the cost of sewage treatment, which is also a great benefit of rain and sewage diversion.

[0003] According to the search of application No. CN202123355931.8, a rain and sewage diversion treatment equipment is disclosed, which is used for rain and sewage diversion treatment. The rain and sewage enter the water inlet pipe, impact the horizontal plate and the impact plate, and the return spring is compressed. The short rod drives the movable ring to move on the inner wall of the water inlet pipe to remove dirt, so as to avoid serious deposition at the pipe opening position and blockage caused by adhesion to the inner wall of the pipeline, improve the dredging effect, and at the same time, the sludge and other large particles are left in the filter box, the rainwater enters the bottom of the box, the gear drives the push rod to extrude the filter box to extend the discharge port, so as to avoid the removal of sludge, improve the cleaning effect.

[0004] The existing rain and sewage diversion treatment equipment separates rainwater and sludge by filtration, but the particle size distribution of solid impurities in rain and sewage is relatively discrete, and it is difficult to achieve good separation effect by relying on a group of filter screens. Secondly, solid impurities are deposited on the upper end surface of the filter plate after filtration, and with the accumulation of solid impurities, the filtration capacity of the filter plate gradually decreases, so the filter plate needs to be removed for cleaning before secondary use, which is time-consuming and laborious. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a kind of filter and processing equipment of rain and sewage diversion to solve the problems raised in the above background technology.

[0006] In order to achieve the above object, the utility model provides a filter and treatment equipment of rain and sewage diversion, including equipment main part, the filter assembly is installed in the equipment main part cavity, the filter assembly bottom is installed with collection component, the filter assembly includes drive motor and installation frame, a plurality of groups of filter plates are slidably connected in the installation frame, the rain and sewage are filtered layer by layer through a plurality of groups of filter plates, the drive motor drives the installation frame rotation 180 degrees, the filter residue on the filter plate upper end is cleaned, the collection component collects the cleaned filter residue.

[0008] As further preferred, the installation frame inner wall is spaced apart and is provided with a plurality of groups of installation grooves, a plurality of groups of filter plates include primary filter plate, secondary filter plate and tertiary filter plate, a plurality of groups of filter plates are installed in a plurality of groups of installation grooves from top to bottom in order of gradually reducing filter hole diameter.

[0009] As further preferred, the filter plate upper end edge is fixedly connected with a plurality of groups of elastic components, a plurality of groups of elastic components are fixedly connected on the corresponding installation groove top away from the filter plate side.

[0010] As further preferred, the collection component includes a porous support plate, a collection tank is installed on the upper end surface of the porous support plate, a support spring is fixedly connected to the bottom of the treatment box inner chamber away from the porous support plate side.

[0011] As further preferred, the collection tank bottom is fixedly connected with a limiting block, a limiting sliding groove is formed in the upper end surface of the porous support plate, and the limiting block is slidably connected in the limiting sliding groove.

[0012] Through the above technical scheme, the filter and treatment equipment of rain and sewage diversion has the following gains:

[0013] 1. This utility model, through the installation of a filtration assembly, allows rainwater and sewage to enter the inner cavity of the treatment chamber via a rainwater and sewage pipe. The sewage is then distributed onto the upper surface of the primary filter plate via a dispersion port. The rainwater and sewage undergo progressive filtration through the primary, secondary, and tertiary filter plates. Rainwater passes through a collection assembly and collects at the bottom of the treatment chamber before flowing out through a drain pipe. As sediment accumulates on the upper surface of the filter plate, the elastic component gradually extends until the filter plate contacts the bottom of the mounting groove, closing the rainwater and sewage pipe. At this point, the drive motor rotates the mounting frame 180 degrees, causing the sediment on the filter plate to fall into the collection basin under gravity. Inside the manifold, opening the rainwater and sewage pipe allows the impact force of fresh rainwater and sewage to flush the back of the filter plates, causing the deposits on the front of the filter plates to fall off and quickly renew the filter plates. When the filter plates are impacted, the elastic components deform, and the reaction force of the elastic components pushes the filter plates upward, causing the filter plates to vibrate and further promote the shedding of deposits. After the filter plates are renewed, the rainwater and sewage pipe is closed, the drive motor rotates to reset the mounting frame, and the rainwater and sewage pipe can be opened again to continue filtering rainwater and sewage. By automatically renewing the filter plates, the effective service life of the filter plates is extended and the efficiency of rainwater and sewage separation is improved.

[0014] 2. This utility model, by setting up a collection component, allows the cleaned sediment to fall into the collection box. Rainwater in the sediment and rainwater from the cleaning filter plate are filtered through the collection box and the porous support plate and converge at the lower end of the treatment box cavity. As the sediment in the collection box increases, the collection box pushes the porous support plate to compress the support spring and move downward. When the sediment in the collection box reaches a set amount, the porous support plate moves to the same height as the lower edge of the slag removal port, opens the slag removal port, and pulls out the collection box for unified treatment of the sediment. When the collection box moves, the limiting block slides in the limiting groove to prevent the collection box from shifting and being unable to move smoothly out of the slag removal port.
