Description

The mud reflux of anti-secondary come-up

Technical field

The utility model relates to a kind of sewage disposal device, relates in particular to a kind of mud reflux.

Background technology

Bioremediation has been widely used in the middle of the treating processes of various waste water, and also there is wider space in the research of himself.Generally speaking, the operation of the biological treatment of waste water all needs to carry out mud and refluxes, for example be back to the initiating terminal of treatment process, keep the concentration of mud and, make biological treatment integral body can keep stablizing and high-level efficiency the adaptability of processing waste water from second pond.

But in the actual moving process, the degree of difficulty that the higher viscosity of mud refluxes mud greatly increases.Simultaneously, if mud refluxes inhomogeneous and return flow can not satisfy requiring of technology the time, original sedimentary mud can lump and emerge, and forms the secondary come-up, directly influences the water quality (COD etc.) of water outlet.

Traditional mud reflux technique is to adopt fixed returned sluge pipeline, in conjunction with the flow characteristics and the action of gravity of mud, extracts the front end of mud to corresponding biological treatment from mud-collecting slot.As the patent No. is the mud reflux of the disclosed no energy consumption sewage disposal device of CN01213872.X, comprise pollution discharge pond, be equipped with in it and lead to outer blow-off pipe, filter inleting pipe is housed in the mudpan, filter inleting pipe inserts the filtration vessel bottom that a material filtrate is housed, and the mudpan bottom is equipped with unidirectional sludge valve and mud return line, on another partition wall top water outlet is arranged.This patent structure is simply compact, make easy to use, simple and convenient management, safe and reliable, the cycle of drawing clearly is long, but because the viscosity of mud itself makes this patent design still can't avoid accidental mud rising phenomenon in mud refluxes this process, especially for these large-scale Sewage treatment systemss (terminal away from initial end), then need higher power, the existence of mud viscosity makes reflux course that the problem that refluxes and have some setbacks even block because of the not enough pipeline of power can take place.

Summary of the invention

Above-mentioned for solving owing to the higher viscosity of mud, the secondary come-up of the mud that causes caking, and uneven mud density makes a mud backflow difficult technologies difficult problem, the mud reflux that the utility model provides a kind of anti-secondary to float.

The utility model is a kind of mud reflux of anti-secondary come-up, comprise sludge return pipe, sludge sump, sludge return pipe is placed in this sludge sump, the sludge return pipe lower end is provided with collection mud cover, the upper end of sludge return pipe is communicated with road and gas channel, be provided with reverse checkvalve in the gas channel, described collection mud cover is provided with annular gas distribution pipe, the annular gas distribution pipe is communicated to collection mud cover inside at a certain angle by plurality of nozzles, and described sludge return pipe is connected with telescoping handle by angle demodulator.The collection mud cover of the utility model design plays the effect of collection mud, the mud that blows afloat is controlled in the respective range, collect the mud cover simultaneously and can also play the effect of water conservancy diversion the aspiration procedure of peristaltic pump, thereby reinforcement pumping efficiency, inhaling under the limited prerequisite of journey, efficiently finish the following flow organization effect of inhaling, the raising mud extraction efficiency served of mud in the collection mud cover.One of pipeline is normal sludge return pipe, and another then is the gas channel by reverse checkvalve and air UNICOM, and reverse checkvalve is opened when forming negative pressure in the line clogging sludge pipe, and introducing air prevents the obstruction of pipeline.At the variation of sludge settling position normal direction, annular gas distribution pipe can dynamically be adjusted in the collection mud cover and the angle of nozzle, strengthens the efficient of pressure-vaccum.Concrete difference according to the differing capacities device degree of depth, but the handle portion of device is set to the concertina type of manual regulation in actual application, in addition, by the angle that angle demodulator can be regulated vertical sludge return pipe and telescoping handle easily, allow this mud reflux can move to any old place of sludge sump.

As preferably, described collection mud cover bottom margin place is provided with some pillars.The pillar of collection mud cover bottom margin device can be used for preventing to collect the mud shroud rim and contacts too closely with mud, reduces resistance and is convenient to collect moving of mud cover.

As preferably, described collection mud cover is tapered, and the lower opening cross section is more than 10 times of sludge return pipe.The collection mud cover that design has enough areas can stop effectively that mud disperses come-up, can play the effect that reinforcement sludge reclaims simultaneously.

As preferably, described annular gas distribution pipe connects aeration pump by the tracheae branch road.The work of aeration pump is constantly by rami tracheales road direction annular gas distribution pipe air feed, and annular gas distribution pipe sprays air-flow with different angles by nozzle in collection mud cover, the mud that sticks at the bottom of the pond is blown afloat, so that reflux, different angles can be controlled the angle that mud rises.

As preferably, be provided with in the middle part of the described telescoping handle and hold back tube support.Hold back tube support and the mud tube portion can be converged in the corresponding position.

As preferably, described sludge return pipe connects peristaltic pump by road.The work of peristaltic pump constantly is back to the front end oxidation pond by sludge return pipe with mud.Generally do not adopt continuous operation, and adopt the periodic running method, the resting period need be adjusted accordingly according to handled waste water quality and the treatment process feature that is adopted.

As preferably, the pipeline of described road and tracheae branch road all adopts flexible materials.Flexible materials can guarantee that mud refluxes smoothly, also makes things convenient for moving arbitrarily of mud reflux.

As preferably, described gas channel outer port part is provided with the clear liquid capsule.In sludge return pipe, form negative pressure, and when opening reverse checkvalve, the lubricant in the clear liquid capsule can in sucking sludge return pipe, gas channel help to accelerate backflow efficient along the mud in threading a pipe just.

As preferably, described telescoping handle connects outside power equipment.Improve mud reflux level of automation.

The utility model is a kind of reflux of mud efficiently, it plays the effect of collection mud by taper collection mud cover, the mud that blows afloat is controlled in the respective range, collect the mud cover simultaneously and can also play the effect of water conservancy diversion the aspiration procedure of peristaltic pump, thereby the reinforcement pumping efficiency is being inhaled under the limited prerequisite of journey, and that efficiently finishes mud in the collection mud cover serves the flow organization effect of inhaling down, improve the mud extraction efficiency, prevent the secondary come-up of mud.In addition, by the gas channel of reverse checkvalve and air UNICOM, open when forming negative pressure in the line clogging sludge pipe, introducing air prevents the obstruction of pipeline, and it is more smooth and easy to allow mud reflux, and sludge concentration is more even.
