Abstract

A slag extractor of a household biogas digester in country mainly comprises a detention chamber, an overflow pipe, a check valve, a soft conduit, a pumping conduit and a fixing plate; the overflow pipe is connected with the upper outer wall of the detention chamber; a feeding pipe joint is connected with the bottom of the detention chamber; the diameter of the check valve is slightly smaller thanthe inner diameter of the detention chamber; the check valve is placed on a feeding port at the inner bottom of the detention chamber; and one end of the soft conduit is connected with the feeding pipe joint at the lower part of the detention chamber, and the other end thereof is connected with the pumping conduit. When the extractor is fixed, the pumping conduit can be directly inserted into a discharge pipe of the biogas digester, so as to supply fresh feedings and extract slag frequently under the condition that the biogas digester doesn't stop production; the installation and the use are simple and convenient, no power is needed, the energy is saved, the environment is protected, and the slag extractor is economical, safe and practical; and the operation can be finished by only one person, so that the work intensity is low, and the working performance is high. Therefore, the slag extractor provided by the utility model is especially suitable for extracting slag in the country household.

Description

Methane-generating pit for farm household biogas residue liquid withdrawal device

Technical field

The utility model relates to a kind of utensil that biogas residue liquid extracts in the methane-generating pit of family, rural area that is specifically designed to.

Background technology

At present the methane-generating pit for farm household mode of slagging tap has machinery to pump slag, piston-type to take out that the excrement device is slagged tap and the big scarfing cinder in pond is gone in the flip of manual work.More than all kinds of mode of slagging tap a lot of drawbacks are all arranged: mechanical pump price height, and install, remove, use complicated loaded down with trivial details; With piston-type take out that excrement device labour intensity is big, unhygienic, effect ground; The big scarfing cinder in pond is gone in the flip of manual work, wastes time and energy, unhygienic, and natural pond slag gas is more harmful, it is very dangerous that personnel go into the pond, often has casualty accident to take place, and also is subject to the restriction of place and object, promptly getting raw material earlier ready needs the place, and the slag liquid that goes out clearly also need be used place, contaminate environment; From stopping aerogenesis, all need the quite a long time to feeding from new startup; Under the situation in empty pond, to also having a significant impact in work-ing life of methane-generating pit.

Summary of the invention

The technical problems to be solved in the utility model is: design a kind of methane-generating pit for farm household biogas residue liquid withdrawal device, to overcome the deficiencies in the prior art.

The technical scheme that solution the utility model problem is taked is: it mainly is made up of retained chamber, upflow tube, vacuum breaker, flexible conduit, twitch conduit, retaining plate, retained chamber is cylindric, connect a upflow tube at an upper portion thereof on the outer wall, the bottom is connected with a feed-pipe joint; Vacuum breaker is the disk shape, and diameter is slightly less than retained chamber's internal diameter, is placed on the opening for feed of retained chamber's inner bottom part, and the pressure bar that has a diameter to be slightly less than retained chamber's internal diameter is pressed in above the vacuum breaker; Flexible conduit one end is connected on the feed-pipe joint below the retained chamber, and the other end is connected twitches on the conduit; For the ease of fixing, retaining plate is located at the retained chamber bottom.

The outside screw that is provided with suitable for reading of retained chamber, other has the head cap of a carry potential overflow pipe to cooperate with outside screw in the retained chamber; On the head cap of carry potential overflow pipe, be provided with spanner.

Positively effect of the present utility model is: after this utensil is fixed, can directly inject in the feed-pipe of methane-generating pit twitching conduit, under the situation that methane-generating pit does not stop production, accomplish often to replenish virgin material, extract slag liquid; Installation, easy to use does not need any power, energy-conservation environmental protection again, and economic security is practical again; One people just can operate, and labour intensity is low, and the operating efficiency height is particularly suitable for the family, rural area and extracts the biogas residue liquid use.

Description of drawings

Accompanying drawing is the utility model structural representation

Embodiment

As shown in drawings, the utility model mainly is made up of retained chamber 2, upflow tube 1, vacuum breaker 6, flexible conduit 9, twitch conduit 10, retaining plate 7, retained chamber 2 is cylindric, welds a upflow tube 1 with steel pipe on the outer wall at an upper portion thereof, and the bottom is connected with a feed-pipe joint 9; The outside screw that is provided with suitable for reading of retained chamber 2, other has the head cap 4 of a carry potential overflow pipe to cooperate with outside screw in the retained chamber, for the convenient head cap 4 of installing, is provided with spanner 3 in head cap 4 both sides.Vacuum breaker 6 is the disk shape, make by rubber plate, diameter is slightly less than retained chamber's 2 internal diameters, be placed on the opening for feed of retained chamber's 2 inner bottom parts, the pressure bar 5 that has a diameter to be slightly less than retained chamber's 2 internal diameters is pressed in above the vacuum breaker 6, pressure bar 5 can be xyloid also can be metal, main purpose is to prevent vacuum breaker 6 changing of the relative positions; Below retained chamber 2, be provided with a retaining plate 7; Flexible conduit 9 has plastic hose to make, and mainly is to be convenient to bending, and an end is connected on the feed-pipe joint 8 below the retained chamber 2, and the other end is connected twitches on the conduit 10, twitches conduit 10 and is made by plastics tubing.

Using method of the present utility model is: the retaining plate 7 of retained chamber 2 bottoms is fixed on the methane-generating pit body of wall in addition or on the timber, insert in the discharge nozzle of methane-generating pit twitching conduit 10, if directly extract biogas residue liquid, just do not need the head cap 4 above the retained chamber 2.In retained chamber, add earlier the liquid about 1 liter during operation, grasp the flexible conduit 9 of twitching above the conduit 10, up and down reciprocatingly twitch conduit, biogas residue liquid is full of rapidly twitches conduit 10, back and forth cover is carried continuously, forces the biogas residue liquid in the pipe to wash vacuum breaker 6 open, pours in retained chamber 2, constant back and forth cover is carried slag liquid, and biogas residue liquid will constantly be discharged from upflow tube 1.If biogas residue liquid directly is drawn on the higher transport trolley, the head cap 4 of carry potential overflow pipe can be screwed in above the retained chamber 2,, with the sealing of the mouth of pipe of the upflow tube in the retained chamber 21 pipe connecting is connected on the overflow mouth of pipe on the head cap 4 with shutoff, carries out top same operation then.

After the use, extract, remove retained chamber 2, flexible conduit 9 and twitch residual biogas residue liquid in the conduit 10 twitching conduit 10, so as not to for a long time need not, the inside caking results in blockage, influence is used next time.
