Abstract

The utility model discloses a novel septic tank, which is mainly composed of a water inlet pipe, a water outlet pipe, and a flat spherical cylinder body. The utility model is characterized in that the bottom of the cylinder is downwards concave into a circular arc shape; the upper part of a cylindrical waist is hogged. The opening of the hogged top is closed by a top cover. The water inlet pipe and the water outlet pipe are symmetrically arranged at both sides of a neck part. The vicinity of the pipe opening of an inner wall is provided with a plurality of triangular pyramid hanging teeth. When the fouling agent and the water flow into a cavity, the rotation of the fouling agent is driven by the impact force of the water, the suspended agent is partitioned by the hanging teeth, so as to sink, deposit, ferment, generate marsh gas, form the inner pressure, and further speed up the decomposition and the volatilization, because of the reciprocal action, the discharging agent is fundamental clear water. The utility model has the advantage of strong digested ability, is not easy to block the pipeline, is favorable for protecting the environment, and is suitable for the installation of the live building.

Description

A kind of septic tank

The utility model relates to waste disposal plant, a kind of septic tank of more specifically saying so.

Since the seventies, cubes " three grades " septic tank is generally adopted in the sewage disposal of building group, residential quarters, the private residence in public housing, and planner's subjective wishes is to want to make the dunghill natural sedimentation by storing step by step, melts step by step, becomes easy flowing water at last and discharges.Facts have proved that there is following defective in this cubes " three grades " septic tank: one, occupation of land is many, and the geographical position is selected to be particular about; Two, suspended substance is difficult for decomposing in the pond, and the time one is long, forms plate-like solid from joining line, stops up blow-off line easily; Three, sealing is difficult to handle, and foul smell easily overflows, and influences environmental health, relates to neighborhood relationship.Therefore, this septic tank is left unused in fact mostly or is simply abandoned.

The purpose of this utility model provides a kind of septic tank, it can make the sewage natural rotation that flows in the pond, promoting dunghill follows rotation to be scratched the sinking of disintegrating by hanging breaking, produce biogas through the certain hour secondary fermentation and form interior pressure, further quicken dunghill decomposition and foul smell volatilization in the cylinder, effect makes effusive water be essentially clear water so repeatedly.

In order to achieve the above object, the utility model has been taked following technical solution: this septic tank comprises water inlet pipe and rising pipe, it is characterized in that, it also comprises: a spheroid cylinder body, by cylinder bottom, cylinder waist and cylinder cap constitute, the recessed circular arc dish pot sample that is of cylinder bottom, the cylinder waist is a round shape, be contained on the cylinder bottom, cylinder cap is a circular arc, upwards arches upward, and covers on the cylinder waist, the vault opening, the top cover that is left step by the lower surface periphery covers sealing, and the upper end of top cover flushes with ground, and the inner face of cylinder cap is mentioned near around the lower edge several rows of rhizoma sparganic cone being housed, the zygomorphy ground of cylinder cap respectively has a tilted direction, collar extension is higher than the downward-sloping reservation through hole of internal orifice, water inlet pipe is a straight tube, is inserted in the reservation through hole of a side to stretch in the cylinder body, is 45 with ground, rising pipe is parallel to the ground, and the crooked 135 ° of angles of front end are inserted in the reservation through hole of opposite side and stretch in the cylinder body.

The utility model has the advantages that: 1, take up an area of fewly, the addressing status requirement is not high, has randomness, both can be in indoor installation in outdoor mounted yet; 2, the dirty ability of change is strong, can not produce the line clogging phenomenon, helps environment protection; 3, save time, saving of labor, material-saving, less investment, effect be remarkable; 4, face soil in pond can make full use of.

Fig. 1 is the one-piece construction sectional view of this septic tank.

Fig. 2 is the position view of inlet tube and outlet tube oblique cutting in reserving inclined hole among Fig. 1.

Below in conjunction with accompanying drawing the utility model is done to describe in further detail.

In Fig. 1 and Fig. 2, the 2nd, ground level, the 1st, water inlet pipe, the 8th, rising pipe, the 6th, cylinder bottom, the 5th, the cylinder waist, the 7th, cylinder cap, the 3rd, mention, the 4th, the top flap.As seen from Figure 1, whole cylinder body is a spheroid, it is following to be embedded in ground level, the upper surface of top flap 4 flushes with ground level 2, the cylinder bottom 6 recessed circular arc dish pot samples that are, cylinder waist 5 is a round shape, is contained on the cylinder bottom, cylinder cap 7 is a circular arc, upwards arch upward, cover on the cylinder waist vault opening, the top cover 4 that is left step by the lower surface periphery covers sealing, the inner face of cylinder cap 7 mentions 3 near several rows of rhizoma sparganic cone being housed around the lower edge, and the zygomorphy ground of cylinder cap respectively has a tilted direction, collar extension is higher than the downward-sloping reservation through hole of internal orifice, and water inlet pipe 1 is a straight tube, be inserted in the reservation through hole on the left side and stretch in the cylinder body, be 45 with ground level 2.The angle, from Fig. 2 as seen, the through hole of reservation be tilted direction open into, from Fig. 1 as seen, the through hole of reservation is that collar extension is higher than internal orifice and downward-sloping, rising pipe 8 is parallel to the ground, front end bending 135.Stretch in the cylinder body in the reservation through hole on the right of the angle is inserted in.Water inlet pipe mouth should be higher than effluent pipe mouth, in order to the discharge of water.Reserving via design is that tilted direction feeds, and collar extension to be higher than internal orifice downward-sloping, its objective is that being beneficial to water can reduce resistance to strengthen the impulse force of water along a direction rotational flow.

Cylinder bottom, cylinder waist tube, cylinder cap, top flap are concrete prefabricated element, use sand-cement slurry amalgamation moulding during installation.

After coming into operation, dunghill constantly flows in the spheroid cavity from the mouth of pipe by water inlet pipe together with water, because the impulse force of water drives, produce rotary power, the water and the dunghill of cavity are rotated together, the dunghill that is suspended in the water surface is obstructed with mentioning to bump against in rotary course, owing to mention it is sharp sword rhizoma sparganic cone, be easy to dunghill scratched and make it to disintegrate, through after a while, sedimentary dunghill ferments in water and produces biogas and form interior pressure, quickens further that dunghill decomposes and the volatilization of foul smell, effect so repeatedly, water base that is overflowed by water port has been exactly clear water.
