To solve the above problems, the purpose of the utility model is to provide a kind of sewage treatment anaerobic tank, to the prior art into Row improves, and solves the problems, such as above-mentioned.

The utility model to achieve the above object, a kind of sewage treatment anaerobic tank, pond body and covering including cuboid Cover board in pond body top opening, pond body can be used it is stainless steel welded form, can also be formed using concreting, cover board Intermediate position is provided with the lifter rack through cover board, and teeth are arranged in lifter rack side, and the other side is then plane, lifter rack It is meshed with the driving gear on cover board, driving gear is then meshed with the driving gear of decelerating motor driving, and decelerating motor is logical It is fixed on the cover board to cross bolt, rack gear limit plate is fixed on the cover board of the lifter rack other side, rack gear limit plate is close to lifting The support pulley being in close contact with lifter rack plane side, lifter rack lower end and cover board are fixed in the side side wall of rack gear The intracorporal movable plate in lower section and pond is vertically fixedly connected, and the side wall of movable plate is close to the side wall of pond body, and the bottom of pond body is provided with The water inlet pipe being in communication with the outside then is respectively fixed with outlet pipe that is vertical, and will being in communication with the outside inside pond body on movable plate And exhaust pipe, outlet pipe run through cover board, and can be up and down in cover board, the upper end of outlet pipe passes through solenoid valve and suction hose Connection, exhaust pipe also extend through cover board, and can be up and down in cover board, and the upper end of exhaust pipe is then observed by transparent taper Pipe is connected to gas collection hose.

The movable plate of the utility model level can move up and down under the drive of lifter rack, convenient for making the small table of movable plate Face is thoroughly contacted with the sewage level inside pond body, so as to preferably guarantee that sewage level upper air is less, even There is no air, create good environment for anaerobic environment, is conducive to the transformation efficiency for improving anaerobic bacteria, improves at anaerobism sewage The effect of reason.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, a kind of sewage treatment anaerobic tank, pond body 1 including cuboid and it is covered on 1 top opening of pond body On cover board 2, the medial surface of pond body 1 is smooth, and the intermediate position of cover board 2 is provided with the lifter rack 3 through cover board 2, lifter rack 3 It is vertically arranged, lifter rack 3 is meshed with the driving gear 4 on cover board 2, and the driving rotation of gear 4 can then drive lifter rack 3 It rises or falls, the driving gear 6 that driving gear 4 then drives with decelerating motor 5 is meshed, so decelerating motor 5 rotates, actively Gear 6 can drive driving gear 4 to rotate again, thus control the i.e. controllable rising of lifter rack 3 of the positive and negative rotation of decelerating motor 5 or Decline, decelerating motor 5 are bolted on cover board 2, are fixed with rack gear limit plate on the cover board 2 of 3 other side of lifter rack 7, rack gear limit plate 7 is fixed with the support being in close contact with 3 plane side of lifter rack in the side side wall of lifter rack 3 Pulley 8 by support pulley 8 and drives gear 4 to form 3 points of clamping to lifter rack 3, convenient for lifter rack 3 rise or under Drop, 3 lower end of lifter rack is vertical with the movable plate 9 in 2 lower section of cover board and pond body 1 to be fixedly connected, and the side wall of movable plate 9 is close to pond The side wall of body 1, the bottom of pond body 1 are provided with the water inlet pipe 10 being in communication with the outside, and it is vertical to be then respectively fixed on movable plate 9, And the outlet pipe 11 and exhaust pipe 12 that will be in communication with the outside inside pond body 1, outlet pipe 11 run through cover board 2, and can be in cover board 2 on The upper end of lower activity, outlet pipe 11 is connected to by solenoid valve 13 with suction hose 14, and exhaust pipe 12 also extends through cover board 2, and can Up and down in cover board 2, the upper end of exhaust pipe 12 is then connected to by transparent taper observation tube 15 with gas collection hose 16.

For the ease of controlling the dosage of dosing, the side of water inlet pipe 10 is additionally provided with pipe 17 by the dosing communicated therewith.

In order to improve the leakproofness of 9 surrounding of movable plate, also it is embedded in the side wall of movable plate 9 and is closely connect with 1 inner sidewall of pond body The sealing strip 18 of touching.

For the ease of exhaust, the lower surface of movable plate 9 is provided with the pneumatic trough 19 of taper, and the tip of pneumatic trough 19 and exhaust The lower end of pipe 12 is connected to.

Working principle: the i.e. controllable lifter rack 3 of the positive and negative rotation of decelerating motor 5 rises or falls, when 1 sewage treatment of pond body After reduction, makes decelerating motor 5 that movable plate 9 be driven to move down, so that sewage is first full of pneumatic trough 19, arrived further along exhaust pipe 12, Until sewage arrives observation tube 15 by exclusion, decelerating motor 5 stops after sewage reaches observation tube 15, at this time the sewage in pond body 1 Upper liquid level can preferably carry out anaerobic reaction almost without air, and the gas that anaerobic reaction generates then can be by pneumatic trough 19, row Tracheae 12, observation tube 15, gas collection hose 16 are transported to extraneous collecting device, after sewage treatment, then open solenoid valve 13, it is drawn water by outlet pipe 11, suction hose 14, of course for gas backstreaming is prevented, gas collection hose can be closed at this time Valve at 16, and movable plate 9 slowly moves downwards when draw water, clear water can be extracted by being subject to, and movable plate 9 is too fast downwards It can be determined by observation observation tube 15, be slowed down again at this time.

The standardized element that the utility model uses can commercially, shaped piece according to specification and attached drawing Record can carry out customized, the specific connection type of each part is all made of in the prior art mature bolt, rivet, weldering Equal conventional means are connect, mechanical, part and equipment are all made of in the prior art, conventional model, if be related to being not described in detail Circuit, the circuit connection are also using connection type conventional in the prior art, and this will not be detailed here.

Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, this The those of ordinary skill of technical field, in the essential scope of the utility model, variation, change, addition or the replacement made, all It should belong to the protection scope of the utility model.
