Abstract

The utility model relates to an advanced biological wastewater treatment, an amplitude type and second-time mud absorption machine in a sedimentation tank , in particular to a leak proof exhaust mud device of the absorption machine, being characterized in that the device cut separately a rotational mud collection groove and a central tank which are communicated fixedly and rotational mud collection groove and the central tank exhausting mud through a hanging and crossing mud absorption pipe in communication that overcome the deficiencies of infiltration of waste water into an exhausting cylinder, diluting active sewage sludge caused by leaking which is because of rotating communication between an original central mud tank and central mud exhausting cylinder, and the device without any active elements has the advantage of using reliably hardly with maintenance and operating easily with a simple structure which cannot increase the cost.

Description

Improved radical sedimentation basin scraping and sucking machine mud discharging device

Technical field

Utility model relates to a kind of improved sewage biochemical treatment, and width of cloth streaming secondary sedimentation basins scraping and sucking machine relates in particular to the leak free mud discharging device of a kind of scraping and sucking machine.

Background technology

Existing sewage treatment process radial-flow secondary sedimentation basins scraping and sucking machine, by the suction pipe and the mud-collecting slot of the revolution truss below that is suspended on rotation, and center mud jar that is communicated with mud-collecting slot and the compositions such as center spoil disposal tube that are communicated with the rotation of center mud jar.Pool bottom sludge imports mud-collecting slot with mud by suction pipe under the effect of liquid level difference force, gravity flow enters center mud jar, and entering center spoil disposal tube by center mud jar again derives, and reaches spoil disposal.Yet, its mud discharging device center mud jar is rotation with center spoil disposal tube and is communicated with, its sealing is to rely on rubber pad realization between trim, because both rotations friction, sealing rubber pad very easily weares and teares and causes sealing face leakage, clean and dirt water enters center spoil disposal tube by plane of rotation on making in the settling tank, causes the active sludge water ratio to increase, and concentration diminishes.The dilution that active sludge causes because of the leakage water inlet, the one, increased the follow-up concentration workload of discharge mud; The 2nd, the returned sluge of dilution can not satisfy the subsequent treatment process requirement, and then influences organic matter of sewage subsequent degradation treatment effect.Thereby existing mud discharging device is shorter work-ing life.

Summary of the invention

The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of and can be communicated with derivation mud, do not have rotary seal again, settling tank sewage can not enter center spoil disposal tube, thereby effectively guarantees the radical sedimentation basin scraping and sucking machine mud discharging device of activated sludge concentration.

The utility model purpose realizes, the main improvement is the mud-collecting slot that rotates with truss to be cut off with center mud jar separate, thereby can being adopted, the center mud jar and the center spoil disposal tube of below do not have fixedly being communicated with of rotating, effectively avoided center mud jar to be communicated with the sealing leak that brings because of rotating, rotated between mud-collecting slot and fixed center mud jar and active sludge in the mud-collecting slot is entered center mud jar by suspension mud-absorbing tube with center spoil disposal tube.Specifically, utility model radical sedimentation basin scraping and sucking machine mud discharging device, comprise and be arranged on the mud-collecting slot that rotates the truss below, center mud jar and center spoil disposal tube, it is characterized in that said rotation mud-collecting slot separates with center mud jar partition, center mud jar fixedly is communicated with center spoil disposal tube, rotates mud-collecting slot and is communicated with spoil disposal with dead center mud jar by suspension mud-absorbing tube.

The said unsettled suction pipe of utility model can be power suction type such as pumping formula, also can be the automatic siphon formula, and a kind of better mode is to adopt the automatic siphon formula, can reduce unnecessary power consumption, and because of unpowered, not fragile yet.

Utility model is delivered to active sludge in the mud-collecting slot in the mud jar of center automatically for effectively utilizing siphon pipe, rotates the mud-collecting slot baseplane and should suitably be higher than mud jar baseplane, center, helps siphon like this and carries out; For making the gap spoil disposal or the siphon of working once more can be carried out automatically, the utility model siphon bend is provided with air extractor, gets rid of the siphon inner air tube by air extractor, and siphon is carried out automatically.Air inlet destroys siphon to utility model in siphon is carried out in order effectively to avoid, and stretches bucket under mud-collecting slot is provided with by center mud jar end, relies on competent sludge quantity, effectively avoids the siphon air inlet.

Utility model is owing to will separate with center mud jar partition with the mud-collecting slot that truss rotates, by suction pipe especially siphon pipe active sludge in the mud-collecting slot is delivered to center mud jar, not only reached the dispatch of collection mud, and center mud jar is rotated with truss by former, become and maintain static, thereby can make center mud jar and center spoil disposal tube realize fixedly being communicated with, avoid center mud jar and center spoil disposal tube to leak difficult point, effectively guarantee the discharge activated sludge concentration because of rotating communication seals.And because no-rotary part uses reliably, need not keep in repair substantially, simple in structure, simple for production, do not increase cost again.

Below in conjunction with two indefiniteness embodiment, further specify utility model.

Fig. 2 is the utility model second example structure synoptic diagram.

Embodiment

Embodiment 1: referring to Fig. 1, radical sedimentation basin scraping and sucking machine mud discharging device, comprise the straight-through truss 1.1,1.2 that rotates, be arranged on the truss below and cut off isolating mud-collecting slot 2.1,2.2 with center mud jar 5, center mud jar fixedly is communicated with center spoil disposal tube 6, and two rotate mud-collecting slot 2.1,2.2 is communicated with spoil disposal by suspended span siphon bend 4.1,4.2 respectively with dead center mud jar 5.Two mud-collecting slots are stretched bucket 3.1,3.2 under having by center mud jar end, and electronic siphon gas barrier 7 is arranged on the siphon bend, rotate the mud-collecting slot baseplane and are higher than mud jar baseplane, center.

Embodiment 2: as embodiment 1, with above-mentioned siphon pipe, make pump 7.1,7.2 suction formulas into, and omit gas barrier, can reach the utility model purpose equally.

Utility model siphon gas barrier can also adopt other air extractors.
