Technical Field

The invention relates to the technical field related to sewage treatment, in particular to a rotary type grating machine for efficient sewage filtration.

Background

In the initial stage of sewage treatment, a rotary type grating machine is mostly adopted to filter the sewage so as to remove solid impurities in the sewage.

However, in the actual use process, some sundries with good water absorption, such as cloth, have strong adhesion after being soaked in water for a long time, are easy to adhere to the grating plate after being fished out, and are difficult to naturally fall off by the gravity of the sundries after being transported to the top of the equipment, so that the load of the grating machine is increased, the running speed of the grating machine is reduced, and the sundries adhered to the grating plate can also obstruct sewage filtration, so that the sewage filtration efficiency is low. Accordingly, the present application document provides a high-efficiency rotary type grating machine for filtering sewage.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides a high-efficiency rotary type grating machine for filtering sewage.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a high-efficient type sewage filters uses rotation grid machine, includes the frame, driving motor is installed to the lateral wall of frame, the inner wall of frame is from last to rotating in proper order down and being connected with the action wheel and from the driving wheel, just driving motor passes through reduction gears and is connected with the action wheel transmission, the action wheel is connected through pulling the chain transmission from between the driving wheel, pull and install the grid board on the chain, a plurality of filtration pores have been seted up to the lateral wall of grid board, it is equipped with hollow rubber circle to inlay on the inner wall of filtration pore, the filtration pore internal rotation is connected with the bracing piece, the spout has been seted up to the lateral wall of bracing piece, install the water supply installation to supplying water in the hollow rubber circle in the spout, a plurality of apopores have been seted up to the lateral.

Preferably, water supply installation includes the magnetism slider of sliding connection in the spout, fixedly connected with and magnetism slider complex iron plate on the lateral wall of grid plate, just the spacing groove has been seted up to the interior bottom of spout, sliding connection has the stopper of fixed connection at magnetism slider lower extreme in the spacing groove, fixedly connected with flexible gasbag between the lateral wall of stopper and the spacing inslot wall, flexible gasbag's inlet end and the end of giving vent to anger communicate respectively has one-way feed liquor pipe and one-way drain pipe, just through catheter intercommunication between hollow rubber circle and the one-way drain pipe, inlay on the inner wall of spout be equipped with normal close formula solenoid valve electric connection's spiral coil.

Preferably, the hollow rubber ring is fixedly connected to the side wall of the grating plate, the scraping ring is connected to the filter hole in a sliding mode, the scraping ring is elastically connected with the support rod through a spring, and the spring is made of magnetostrictive materials.

The invention has the following beneficial effects:

1. through the arrangement of the deformable hollow rubber ring, when water flows through the filter holes, the water supply device is driven to operate by water flow power, so that water is continuously drained into the hollow rubber ring, the hollow rubber ring is enabled to swell, the transparent area of the filter holes is reduced, solid impurities in sewage can be intercepted, and when the filter holes operate to the top of equipment, the power supply to the normally closed electromagnetic valve is stopped, the normally closed electromagnetic valve is opened, the water in the hollow rubber ring is drained, the hollow rubber ring is contracted and shrunken, so that the hollow rubber ring slides relative to the impurities adhered to the hollow rubber ring, a driving force is provided for the adhered impurities, and the impurities are promoted to fall off;

2. through the deformable hollow rubber ring, when sundries are transported to the top of the equipment, the hollow rubber ring is shrunken, the surface area of the hollow rubber ring is greatly reduced, so that the attachment area of the sundries is greatly reduced, the attachment effect of the sundries is reduced, and the sundries can fall off by means of dead weight;

3. through the arrangement of the water outlet hole and the normally closed electromagnetic valve, when sundries are conveyed to the top of the equipment, the normally closed electromagnetic valve is opened, and when the hollow rubber ring is shrunken, water in the hollow rubber ring can be squeezed out to impact the attached sundries, so that the falling speed of the sundries is further accelerated;

4. through setting up the scraping ring to and the spring that magnetostrictive material made, can be under the alternating magnetic field that the magnetism slider produced because of the position constantly changes for the spring constantly stretches out and draws back, thereby promotes the scraping ring at the interior round trip movement of filtration pore, can strike off the tiny adhesion of part debris in the filtration pore, can prevent that the filtration pore from taking place to block up, guarantees good penetrating effect and the filtering quality of grid plate.
