Abstract

The utility model relates to a sewage treating device, particularly to a grid dirt removing machine in a fixed and vertical type, which is composed of a dirt removing mechanism, a dirt unloading mechanism, a transmission mechanism, an underwater grid and an electric control system. The utility model is characterized in that a grid is vertical to ground and the dirt removing mechanism is fixed. A transverse beam is arranged above a water path. The transverse beam is provided with a rotary pressing wheel. A dirt removing rake is composed of a rake bucket and a small vehicle. The rake bucket is turned by weight and the pressing wheel on the transverse beam. The rake bucket of the utility model is difficult to be tightly blocked and the land occupying area of the entire machine is small. The utility model has simple structure, high operating reliability and easy automatic controlling realization.

Description

Fixed vertical grid sewage-removing machine

A kind of water treatment facilities can be used for the steam power station, the nuclear power station reclaimed water system is removed floating things such as the vegetation in the water, rubbish.Also be applicable to the supply and drain water system of departments such as metallurgy, chemical industry, urban construction.

Grid sewage-removing machine is a capital equipment of removing the water float thing in the water treatment of power plant system, what use in power plant at present is mobile grid sewage-removing machine mostly, mainly by the mechanism that removes contamination, unload dirty mechanism, transmission mechanism, lateral rows mechanism of car, grid, electrical control system are formed under water.Transmission system is made of three cover motor and reductors, and moving up and down of slusher is provided with a cover motor, and slusher is provided with a cover motor separately from duty to the upset of unloading dirty state, and its upset is by the differential realization of this two covers motor.The scrubbing rake of another kind of form is that two quadric chains are arranged on slusher, and a cover Hydraulic Station is set on the top of spotter, by hydraulic cylinder with guide pulley jack-up or put down the upset that realizes slusher and unload dirt.The complex structure of above-mentioned two kinds of form spotters, bulky, cost is high, fault rate is high.

The utility model provide a kind of simple in structure, operational reliability is high, the automatic vertical grid sewage-removing machine of control of easy realization.

The utility model is taked fixed, grid is that 90 degree are promptly vertical with the inclination angle on ground, the scrubbing rake is made of dolly and slusher, slusher is fixed on the dolly with axle and can rotate around the axis, wire tensioner is fixed on the slusher with axle, be provided with the upset stopping means on slusher, limited block is made by damping material, and the slusher front end is equipped with rake teeth.Above the corresponding water channel of spotter, a crossbeam is arranged, rotating pinch roller is housed on the crossbeam.

Be provided with at the ground location place of spotter and lead dirty plate mechanism, it is formed by leading dirty plate, wire rope, leading block, balancing weight.At the two ends of leading dirty plate steel cable is arranged respectively, wire rope is walked around two pairs of leading blocks, and the other end hangs with the balancing weight that can move along guide groove.

The upset of the utility model scrubbing rake is finished by the deadweight of dolly and the pinch roller of crossbeam respectively, do not need motor, reductor or Hydraulic Station to be set specially for the upset of slusher, can allow rake clear the jumps when running into bigger resistance, slusher is not easy stuck, unlikely causing the accident.Grid machine floor space perpendicular to the ground is little, and complete machine only needs a cover motor, reductor, just can finish the work of removing contamination, and is simple in structure, and the operational reliability height is realized control automatically easily.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 is a construction profile of the present utility model;

Fig. 2 is Facad structure figure of the present utility model;

Fig. 3 is the structure chart of slusher of the present utility model;

One end of wire rope 9 is fixed on the wire tensioner 11 of scrubbing rake, wire tensioner is installed on the slusher 14 by axle 17, the other end of wire rope is fixed on the cable drum, dolly is moved up and down, dolly is made up of dolly body 10 and wheel 15, and slusher 14 is installed on the dolly by axle 16 and 90 degree that can rotate around the axis, and 13 are the upset stopping means, 12 is limited block, and effect is location and damping.Above water channel, there are crossbeam 7 two ends fixing in orbit, two pinch rollers 6,8 have been installed on crossbeam 7.Lead dirty plate 5 usefulness at ground place and spool be fixed on the support, respectively have steel cable 3 to walk around two leading blocks 1,4 respectively at the two ends of leading dirty plate, the other end hangs with the balancing weight 2 that can move along guide groove.

During the beginning scrubbing, motor start-up, the cable drum rotation discharges wire rope, dolly begins along track descending under the action of gravity of scrubbing rake, when arriving the bottom, dolly bottom block 18 bumps against dolly with the track bottom block to be stopped, slusher turns over counterclockwise by deadweight and turn 90 degrees, and rake teeth puts in the grid bar, through time-delay, the motor counter-rotating, dolly drives that slusher is up to carry out scrubbing, and rake teeth is taken away the dirt of tackling on the grid, after dolly arrives ground, collide with the balancing weight 2 of leading dirty plate earlier in dolly top, make and lead dirty plate 5 and be rotated counterclockwise an angle and be in the dirty state that unloads, when dolly was up to the crossbeam position, slusher withstood on the pinch roller 6 on the crossbeam, on 8, turn 90 degrees because of dolly still has a power slusher that makes progress to be turned over clockwise, the dirt in the slusher slides into dirt discharge groove along leading dirty plate.Simultaneously, control device sends signal, and motor shuts down, and so far finishes a working cycles.

Claims

1. this fixed vertical grid sewage-removing machine comprises elevating mechanism, leads dirty plate mechanism, scrubbing rake, crossbeam and pinch roller, guide rail, grid, wire rope hold down gag, it is characterized in that the scrubbing rake adopts two rope traction controls, it be by the band roller can be in guide rail upper and lower mobile dolly and be installed on the dolly by two rotating shafts, and can rotate 90 jiaos, its rear portion and have the slusher that washes tank and form, slusher by the eccentric upset of deadweight, is pressuredly to take turns upset and unload dirt in the bottom on top.

2. the described fixed vertical grid sewage-removing machine of claim 1, respectively there is steel cable at the dirty plate two ends of leading that it is characterized in that leading in the dirty plate mechanism, and wire rope is by two pairs of leading blocks, and its other end hangs with the balancing weight that can move along guide groove.
