Description

High chain type grid cleaner

Technical Field

The utility model belongs to the technical field of the environmental protection equipment, a sewage treatment device's improvement is related to.

Background

The grating machine is a solid-liquid separation device capable of continuously removing impurities in fluid, is an indispensable special device in the production processes of industries such as municipal sewage treatment, water works, power plants, textile, food processing, paper making, leather and the like, and is a solid-liquid screening device commonly adopted in China at present.

Currently, mechanical grating machines applied to sewage treatment plants are largely classified into coarse gratings and fine gratings. The common design grid pitch of the coarse grids is 10-20 mm, and the common types of the coarse grids comprise a steel rope type coarse grid machine and a high chain type coarse grid machine. The common design grid pitch of the fine grids is 4-10 mm, and the common types of the fine grids are a rotary drum type fine grid machine and a rotary type fine grid machine. The rotary drum type fine grating has firm structure, low maintenance frequency, large treatment flow, high slag blocking rate, difficult blockage, self-cleaning and larger single maintenance workload. The rotary fine grid is simple in structure and high in maintenance frequency, but the workload of single maintenance is small, and the special structure can cause fiber winding in sewage to cause overload shutdown. The split type rotary drum fine grating occupies a large area, and the fault of the squeezing system has little influence on water passing and slag discharging. The thin grid of integral type rotary drum area of occupation is less, and the trouble of screw press system can directly lead to thin grid rotary drum jam, and the water yield drops sharply. The fine drum grille needs to be flushed under pressure, so that a matched reclaimed water pressurization system needs to be established. While rotary fine grates are generally not provided with pressurized flushing devices. The drum type fine grille has a small water blocking area, so that the power of the driving motor can be small. The installation accuracy requirement of the rotary fine grid is high, and the level of the rake tooth chain must be ensured.

In summary, the mechanical grills currently applied to domestic sewage treatment plants all have defects of different degrees, particularly, fine impurities and suspended matters cannot be removed, the operation load of subsequent process sections of the sewage treatment plants cannot be reduced, and therefore the purposes of energy conservation and consumption reduction cannot be achieved. Therefore, the development of the pretreatment device for the sewage treatment plant, which is energy-saving, economical, stable, safe, applicable and suitable for the situation of China, has important significance.

Disclosure of Invention

The invention aims to provide a high-chain type grating dirt separator, which overcomes the defects of the conventional grating machine and meets the requirements of small occupied area, low manufacturing cost, high reliability and simple and convenient maintenance and management.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a high chain grid scrubbing machine, includes frame, motor, reduction gear, driving sprocket, driven sprocket, grid, scrubbing harrow, its characterized in that: the motor and the speed reducer are installed at the top of the rack, the driving chain wheel is fixed with an output shaft of the speed reducer, the driving chain wheel is in transmission fit with the driven chain wheel through a chain, the chain is arranged on two sides of the grating, a guide wheel is arranged at the end of the dirt removing rake, and the chain drives the dirt removing rake to reciprocate on a guide wheel track.

Further: the device also comprises a buffer device of the dirt removing rake, and the buffer device of the dirt removing rake is hinged at the tail end of the dirt removing rake handle.

Further: the sewage guide plate is connected with the grids.

Further: also comprises a deslagging mechanism.

The high-chain mechanical grating has the working principle that the driving mechanism drives the dirt removing rake to reciprocate through the rotation of the transmission chain so as to remove the dirt. The dirt removing rake makes the teeth of the dirt removing rake wedged in the gap between the dirt barriers from the bottom of the dirt barriers and move upwards. The dirt that will hold back is scraped at upward motion in-process and is collected, then promotes the filth along leading dirty board, scrapes the slagging-off mouth by the dross removal mechanism with the filth when slagging-off mouth position, accomplishes a scrubbing process so far. And then the decontamination rake moves downwards, when the decontamination rake moves downwards, the rake head picks up the surface of the trash rack and gets to the bottom of the trash rack, and then the next decontamination process is realized.

The utility model discloses for prior art have following beneficial effect lie in: the grid is suitable for deep ponds, such as sewage collection deep well ponds and the like. The effect of removing long fibers, ribbons and other impurities in the sewage is particularly good. The grille occupies a small area. The transmission parts are all above the water surface. The structure is simpler, so the manufacture and the maintenance are more convenient.
