Abstract

The utility model discloses a double-drum crush type grating device which comprises a body. A drive device is disposed on the upper surface of the body. Flow passing drums, a primary blade set, an auxiliary blade set are mounted in the body. The primary blade set is connected with a driving shaft on the drive device. The auxiliary blade set is connected with a transmission shaft on the drive device. A driving gear fixed on the driving shaft is meshed with a transmission gear fixed on the transmission shaft. The driving gear and the transmission gear move in opposite directions. The driving gear and the transmission gear drive one flow passing drum respectively. The flow passing drums move in opposite directions. The double-drum crush type grating device has small site area and is low in noise and stable in water passing amount. By the double-drum crush type grating device, larger solid impurities can be crushed thoroughly, management cost of a pump station is lowered, work efficiency of a sewage pump is improved, and service life of the sewage pump is prolonged.

Description

A kind of double rotating drum crush type grid device

Technical field

The utility model relates to the blocked sewage water-freeing arrangement of a kind of WWT water-in or pumping plant sewage inlet, relates in particular to a kind of double rotating drum crush type grid device.

Background technology

Existing, all have sewage work in the city in order to handle the sewage of discharging, municipal effluent mainly is divided into two big types, i.e. sewage and trade effluent, some comprises factory effluent and the rainwater of holding back.In sewage treatment process, need to use residual sea water pump that sewage is discharged, but in sewage, can have some tiny solid impurities;, these impurity can influence the working efficiency of residual sea water pump after getting into residual sea water pump; Serious meeting damages residual sea water pump, greatly reduces the work-ing life of residual sea water pump, and existing method is to install fixed-grid additional at the blowdown water-in; In the main interception sewage greater than the solid impurity of 20mm; Carry out manual work to the particle of intercepting then and salvage, in order to protection residual sea water pump, the working efficiency and the work-ing life of improving residual sea water pump.

But there is following weak point in prior art: 1, existing grid in use for some time; Can pile up some solid impurities on the grid makes the sewage quantity that passes through diminish or obstruction fully; At this moment need carry out manual work and salvage cleaning, increase the handling cost of pumping plant; 2, because existing grid is that the solid impurity that is deposited in after for some time on the grid can give off an unpleasant smell under exposing in the open; 3, because unstable through the sewage quantity of stationary grizzly, follow-up WWT work causes problem easily.

The utility model content

Deficiency to prior art; The utility model technical problem to be solved is to provide a kind of double rotating drum crush type grid device; This device can increase sewage and cross the water yield and can not stopped up by rubbish again; And can pulverize bigger solid impurity, equipment is as a whole, is convenient to install, lifts by crane, maintains.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of double rotating drum crush type grid device, comprise body, and described body upper surface is provided with a drive unit, and overcurrent rotary drum, main blade group, auxiliary-blade group are installed in the body; Described main blade group links to each other with main drive shaft on the said drive unit; Described auxiliary-blade group links to each other with transmission shaft on the said drive unit; The driving toothed gear that is fixed on the said main drive shaft is meshing with each other and move toward one another with the transmitting gear that is fixed on the transmission shaft; Described driving toothed gear and transmitting gear be overcurrent rotary drum of transmission respectively, and the overcurrent rotary drum is move toward one another also.

Further, described drive unit is made up of motor, step-down gear, and said step-down gear is fixedly connected with joint flange with said main drive shaft.

Further, described overcurrent rotary drum is provided with the grid filter screen.

After adopting such scheme; The beneficial effect of the utility model is: 1, basis is novel can thoroughly pulverize bigger solid impurity; Solid impurity after the pulverizing can not damage residual sea water pump through residual sea water pump, therefore need not the labor cleaning, has reduced the handling cost of pumping plant greatly; 2, this novel land area is little and can all be buried in undergroundly, reduces the equipment running noises, does not also have foul smell to discharge, and reduces environmental pollution; 3, the sewage output is stable, helps follow-up WWT work.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to detail.

What the utility model disclosed is a kind of single-drum crush type grid device, like Fig. 1, shown in Figure 2, comprises body 1; Described body 1 upper surface is provided with a drive unit 2, and overcurrent rotary drum 3, set of blades 4, main drive shaft 5, transmission shaft 6, driving toothed gear 7 are installed in the body 1, and drive unit 2 comprises step-down gear 21 and motor 22; Motor 22 lower ends are connected with the upper end of step-down gear 21, and said step-down gear 21 is fixedly connected with said main drive shaft 5 usefulness joint flanges 9, and joint flange 9 upper ends are connected with step-down gear 21 lower ends; The lower end of joint flange 9 is connected with main drive shaft 5, and the rotation of motor 22 control main drive shafts 5 has main blade group 41 and driving toothed gear 7 on the main drive shaft 5; Auxiliary-blade group 42 and follower gear 8 are installed on the transmission shaft 6; The driving toothed gear 7 that is fixed on the main drive shaft 5 is meshing with each other and move toward one another with the follower gear 8 that is fixed on the transmission shaft 6, overcurrent rotary drum 3 of driving toothed gear 7 and transmitting gear 8 difference transmissions, and overcurrent rotary drum 3 is move toward one another also; In addition, overcurrent rotary drum 3 is provided with grid filter screen 31.

As shown in Figure 3; During use; Motor 22 energisings are rotated, and drive the main drive shaft 5 that is connected with step-down gear 21 and rotate, and driven shaft 6 obtains to rotate together from power through driving and driven

gear

7 and 8 with major and minor set of

blades

41 and 42; Simultaneously, overcurrent rotary drum 3 also obtains to rotate from power through driving and driven gear 7 and 8.After sewage gets into this device; The rubbish of a part directly gets into to pulverize to distinguish and pulverizes; The rubbish of a part is stopped by the grid filter screen 31 of overcurrent rotary drum 3; Overcurrent rotary drum 3 is delivered to the rubbish that stops through circumferential motion in opposite directions and is pulverized the district and pulverize, and major and minor set of

blades

41 and 42 move toward one another make to get into and pulverize the bulk rubbish of distinguishing and become tiny granulated garbage, and the small garbage particle after the pulverizing is along with sewage flows to downstream together.

Above embodiment is the preferred embodiment of the utility model; Only supply the usefulness of explanation the utility model, but not to the restriction of the utility model, the technician in relevant technologies field; Under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to the category of the utility model.
