Abstract

The invention relates to a rocker string bag type grating slag removing machine in waste water treatment. The slag removing string bag device comprises parallel steel guide rails, a ground hanger rod and a steel string bag, wherein the steel string bag is manufactured by adopting metal grid bars with a certain interval and a frame according to slag removing requirements; the steel string bag is arranged on the parallel steel guide rails; and waste water passes through the steel string bag to achieve the purpose of intercepting and filtering to remove the slag. The steel string bag is lifted to the ground by the ground hanger rod to periodically clean the intercepted dirt in the string bag. The slag removing string bag device can realize the function of cleaning coarse dirt at the preceding stage in middle and small-scale waste water treatment plants, and can replace thick and thin grids arranged in the general waste water treatment plans. The device has good slag removing effect, simple manufacturing, low cost, simple slag removing operation, strong practicality and no energy consumption and maintenance expense of equipment.

Description

Rocker string bag type grating slag removing machine in the WWT

Technical field

The invention belongs to technical field of sewage, be specifically related to a kind of easy sewage deslagging device.

Background technology

Scarfing cinder equipment generally is used on the irrigation channel of WWT or promotes the ingress of pumping plant water collecting basin; Main effect is to remove bigger suspension or swimmer in the sewage; Processing to alleviate follow-up water technology is loaded, and plays effects such as protection water pump, pipeline, instrument.

Main clinker removal method adopts grid both at home and abroad at present.By varying in size of grid interval of grid strip, grid is divided into 3 types of coarse rack, middle grid and fine facks.Press the clinker removal method of grid, two kinds of artificial grid and mechanical grilles are arranged.Mechanical scarfing cinder equipment commonly used has three kinds, i.e. chain, movable type and rope traction formula grilling trash remover.When the interception the grid quantity of slag greater than 0.2m ³During/d, generally adopt mechanical scarfing cinder mode; The grid quantity of slag is less than 0.2m ³During/d, can adopt artificial scarfing cinder mode, also can adopt mechanical scarfing cinder mode.Facts have proved whether grid is selected suitable, directly influences the operation of whole water processing establishment.Artificial grid generally is used for the small-scale sewage treatment station, simple structure, and labour intensity is big.Mechanical grille generally is used for big-and-middle-sized sewage work, and this type grid construction is complicated, and level of automation is higher, and the equipment operation and maintenance cost is higher.

Characteristics in conjunction with middle and small scale sewage work operational conditions and above clinker removal method can be known; The not enough economical adaptation of existing machinery deslagging device; The Prosthesis is not easy to operate, to samll cities and towns' WWT characteristic, develops a kind of more easy slag cleaning device and has meaning.

Summary of the invention

The present invention is directed to the problem that above existing scarfing cinder equipment exists; And, a kind of easy rocker string bag type grating slag removing machine is proposed to the impracticability of middle and small scale sewage work, realize the suspension bigger in the sewage or the removal of swimmer; Device is made simple; With low cost, scarfing cinder is easy and simple to handle, and does not have energy consumption and equipment maintenance cost.

A kind of easy rocker string bag type grating slag removing machine that the present invention proposes, structure is following:

Said scarfing cinder machine is made up of parallel steel track, ground derrick system and the steel string bag three parts.

Said parallel steel track is defaulted in pump well or the equalizing tank according to steel string bag size by two steel tracks;

Said ground derrick system is made up of suspension rod, lifting rope and pulley, and is fixed on the service platform, is used to lift the string bag.Lifting rope is supported by suspension rod, an end hook cat net pocket, and the other end is connected with rocking arm.

The said steel string bag is the rectangle frame pocket of being made up of metal grizzly bar and framework according to the slagging-off requirement, and it is placed on the parallel steel track, can slide along track, and hook block is carried out by the ground derrick system in the top.The steel string bag is arranged two in orbit, realizes alternation.And the position that guarantees the string bag is lower than absolute altitude at the bottom of the water inlet pipe pipe of pretreatment pool, and the string bag of working order just in time places the water inlet pipe below, so that the swimmer that gets in the pond is tackled.

The simple and easy sewage slagging-off string bag device that the present invention relates to is applicable to the removing of front end bigger suspension of water inlet of middle and small scale sewage work and swimmer.Device mainly utilizes the steel string bag to the interception filteration through sewage, thereby realizes the scarfing cinder function, to alleviate the processing load of follow-up water technology, to guarantee the works better of subsequent disposal structures or equipment.Said device scarfing cinder ability is strong, easy and simple to handle, and device is made simple, and is with low cost, and do not have energy consumption and equipment maintenance cost.This device removes and is used for sewage work's front end scarfing cinder, can also be used for the drainage pumping station front end that other contain suspension or swimmer.

Among the figure: the derrick system 5-metal frame 6-metal grizzly bar 7-rocking arm 8-pretreatment pool of 1-water inlet pipe 2-string bag 3-guide rail 4-ground

The practical implementation method

Specify structure of the present invention below in conjunction with accompanying drawing:

(1) referring to Fig. 1 and Fig. 3 when pretreatment pool 8 carries out earthwork construction; Parallel steel guide rail 3 two ends are embedded in the pool wall; Its parallel distance is confirmed according to the steel string bag 2 sizes; Guide rail 3 is buried absolute altitude underground should be high greater than the pretreatment pool liquid level absolute altitude+string bag, and be lower than absolute altitude at the bottom of water inlet pipe 1 pipe, to guarantee that into water gets into pretreatment pool through string bag interception back.

(2) referring to Fig. 2 and Fig. 4; The steel string bag 2 adopts metal grizzly bar 5 and metal frame 6 to be made; Its size and interval of grid strip are decided according to maximum flooding velocity, contained suspended substance kind and cleaning cycle; Make and adopt the steel material welding, hang on the parallel steel guide rail 3, adopt the design of the using and the reserved principle through hangers.

(3) ground derrick system 4 is fixed on the service platform, is made up of suspension rod, lifting rope and pulley, and lifting rope is supported by suspension rod, an end hook cat net pocket, and the other end is connected with rocking arm 7, utilizes rocking arm that the steel string bag is gone up and down, to realize the cleaning to dirt in the string bag.

(4) string bag cleaning cycle is confirmed according to water inlet dirt kind and content.
