Abstract

The invention relates to a sludge discharge device for sewage treatment. A sludge receiving discharge filter plate is arranged in the conveying section of a sludge discharge passage along the length direction, and a plurality of groups of pneumatic nozzles are arranged at equal intervals below the sludge receiving discharge filter plate and form a certain spraying angle with the sludge receiving discharge filter plate; the inlet section of the sludge discharge passage is an unsymmetrical passage, one side of the unsymmetrical passage is provided with an inclined wall, the other side of the unsymmetrical passage is provided with an arc wall, and the inlet section is communicated with the conveying section by a transition section with a certain camber. The invention can combine the boosting process, the condensation process, the sludge-water separation process, the pneumatic step sludge discharge process, and the like into a whole, has the advantages of small size, light weight, easy operation, convenient maintenance and reliable operation, particularly realizes condensation and sludge-water separation in the sludge discharge process and greatly reduces the sewage treatment cost and the energy consumption.

Description

The mud discharging device of sewage disposal

Under technical field the present invention relates to a kind of water treatment facilities, particularly a kind of being used for to industry and the mud discharging device handled of civil sewage.

Background technology

Background technology is for the processing of industry and civil sewage, and the mud discharging device that adopts has strainer drum-type mud, horizontal helical type centrifugal mud and water separator, various soil discharging facilities such as plate and frame filter press usually.Drawbacks such as above soil discharging facility ubiquity process facility preparatory condition in early stage harshness, complexity.As strainer drum-type mud, for reaching best sludge discharge effects, need to be equipped with facilities such as concentration basin, mixing pit, the water content that spoil disposal is advanced into the mud mixture of strainer drum-type mud is carried out strictness control.Used affiliated facility floor space is big, construction cost is high so exist, problems such as the affiliated facility investment is big, operating cost height.

Summary of the invention

Summary of the invention the object of the present invention is to provide that a kind of occupation area of equipment is little, treatment process is simple, cost is low, simplifies the mud discharging device of the sewage disposal of sewage treatment process.

For achieving the above object, the spoil disposal passage of the mud discharging device of sewage disposal of the present invention is to be made of the entrance that is connected, changeover portion and transportation section, in the transportation section of spoil disposal passage, be provided with the mud filter plate that runs in along its length, run in mud filter plate below is provided with some groups of air-blast atomizers by spaced set, air-blast atomizer and run in and have certain jet angle between the mud filter plate, jet angle is the 10-70 degree.

After adopting said structure, mud on the mud filter plate is run under the effect of air-blast atomizer interrupted injection gas in the transportation section of spoil disposal passage, form with step motion is advanced forward, in this motion process, can powerfully advance and concentrate, mud-water separation is more thorough, makes the mud that arrives the exit reach discharge standard.

The conveying of described spoil disposal passage is obliquely installed.

As a further improvement on the present invention, the entrance of spoil disposal passage is an asymmetric channel, and a side of passage is provided with inclined wall, and opposite side is an arcwall, and the changeover portion of entrance through having certain camber is communicated with the transportation section.

Adopt this structure, a part of mud of ingress is directly entered on the mud filter plate that runs in of transportation section to deposit, another part mud changes direction after sinking to the inclined wall of entrance, form the boosting of the falling mud sludge settling that rolls, effectively prevent from the mud sinking process jam to take place, guaranteed the unimpeded of spoil disposal passage.

Described air-blast atomizer interrupted injection air-flow.

Advantage of the present invention is: can be with boosting, concentrate, processes such as mud-water separation, pneumatic stepping spoil disposal are integrated, the volume of mud discharging device is little, in light weight, simple to operate, easy to maintenance, reliable, in the spoil disposal process, realize concentrated, mud-water separation, reduced cost of sewage disposal and energy consumption to the utmost.

Description of drawings Fig. 1 is the structural representation of the mud discharging device of sewage disposal of the present invention.

Description of drawings

The specific embodiment is described further below in conjunction with the mud discharging device of accompanying drawing to sewage disposal of the present invention:

The specific embodiment

As shown in Figure 1, the spoil disposal passage of mud discharging device is to be made of the entrance 1 that is connected, changeover portion 2 and transportation section 3, entrance is an asymmetric channel, one side of passage is provided with inclined wall 4, opposite side is an arcwall, by the setting of inclined wall, can make the mud that enters entrance form the assist of mud of rolling in advancing, effectively prevent the obstruction of mud, guarantee that mud enters the transportation section smoothly.The inlet of spoil disposal passage is provided with flange 12, and the outlet of spoil disposal passage is arranged on the end of transportation section, and its port is provided with the valve 6 of being opened, being closed by drive unit 5 controls, and wherein drive unit and valve arrangement can adopt any-mode according to working condition requirement.The transportation section channel end is inclined upwardly and is arranged on the support 7, also can be horizontally disposed with, and is provided with the mud filter plate 8 that runs in it along its length, and passage is divided into two parts up and down.Be provided with 3 groups of air-blast atomizers 9 of spaced set in the space below the mud filter plate that runs in.Certainly can be not limited to 3 groups.Air-blast atomizer and run in and have certain jet angle between the mud filter plate, between the 10-70 degree, present embodiment is 45 degree usually.Air-blast atomizer is communicated with the gas source control system that is arranged on the passage outside, and gas source control system is controlled nozzle interrupted injection air-flow with the pulse mode stepwise operation.The lowest part of transportation section passage is provided with the discharge outlet 11 by valve 10 controls.

The course of work of the present invention is: the porch that enters mud discharging device through the mud of operations such as filtering-depositing processing, this moment, a part of mud directly entered on the mud filter plate that runs in of transportation section to deposit, another part mud changes direction after sinking to the inclined wall of entrance, the boosting of falling mud of form rolling mud enters the transportation section and runs on the mud filter plate, effectively prevent mud sinking process generation jam, guaranteed the unimpeded of spoil disposal passage.Fall into starting stage of the mud filter plate that runs at mud, the outlet valve of transportation section passage is closed, and along with constantly entering of mud, valve is opened automatically, and remains on this state.Run in mud on the mud filter plate under the effect of the batch (-type) gas jet of air-blast atomizer, form with step motion is advanced forward, realize further that in this motion process powerful the propelling concentrates, make mud-water separation more thorough, finally make the mud that arrives the exit reach discharge standard.The ponding of mud filter plate below of running in can be discharged reuse by discharge outlet.
