CN201052974Y - Sewage backwater pool blocking-proof device - Google Patents

Abstract

The utility model discloses a sewage reclaiming tank anti-block device which comprises a separation net and a sludge stirring part, wherein, the separation net is arranged inside a sewage reclaiming tank and above the probe of a liquid level meter; the sludge stirring part further comprises a compressed air input pipe and a blowing pipe; the compressed air input pipe is communicated with the blowing pipe, while the blowing pipe is arranged at the bottom of the sewage reclaiming tank and is provided with a blowing hole. The anti-block device separates the floating rubbish in the sewage reclaiming tank from the probe of the liquid level meter and the suction pipe of a sludge pump through the separation net to prevent the probe from being wrapped and the suction pipe from being blocked up; therefore, the anti-block device prevents environmental pollution caused by sewage overflow, and ensures normal operation of the sludge pump, reduction in maintenance time and prolonged service life of the sludge pump; compressed air blowing is realized through the sludge stirring part to prevent the suction pipe of the sludge pump from being buried due to sediment siltation, thereby ensuring the operation safety of the sludge pump; in addition, sludge does not need to be cleaned regularly, thereby saving cost and increasing work efficiency.

Description

Sewage back pool antiplugging apparatus

Technical field

The utility model relates to the supplementary unit of sewage disposal, more particularly, relates to a kind of sewage back pool antiplugging apparatus, and this antiplugging apparatus can guarantee that slush pump normally moves.

Background technology

In order to protect environment, to reduce industrial pollution and recycle resource; see also shown in Figure 1; steel-making enterprise generally all adopts the various sewage that are difficult to recycle in 1 pair of smelting process of sewage back pool to compile at present; and then adopt slush pump 2 with the sewage transport in the sewage back pool 1 to wet dust removal control of dust tank; after precipitation, filtration and dosing are handled, just can be for reusing.This slush pump 2 detects back pool 1 median water level by liquidometer 4 and controls start and stop, and when water level was lower than certain level value, slush pump 2 shut down; When water level was higher than certain level value, slush pump 2 just began to start.To keep the certain water level of back pool 1.But because this sewage back pool 1 is arranged on walkway one side of zero rice platform, cause in the back pool 1 various floating refuses 3 many especially, for example foam food boxes, plastics, paper etc., all swim in above the water surface and and move with ripples, when floating refuse on the water surface 3 increases, sometimes liquidometer 4 probes are wrapped up, cause liquidometer 4 to lose efficacy, thereby can't control slush pump 2 operations preferably.If in time do not find, cause slush pump 2 to move continuously easily, drain the sewage in the pond, make a large amount of air of suction of slush pump 2,, waste energy if the untimely slush pump 2 that causes easily of exhaust dallies, if retaining once more in the pond, this moment, slush pump 2 just can't effectively draw water, and caused sewage outflow easily, caused environmental pollution.If floating refuse 3 is sucked and stops up by slush pump 2, and enter slush pump water tank 5, all can cause slush pump 2 to work preferably, even cause slush pump 2 to damage.In addition, also because back pool 1 has compiled the sewage of flowing through everywhere, also can bring various foreign material, particularly a large amount of silt, and form mud 6 at the bottom of sinking to the pond, if irregularly cleaning, the tail pipe 21 of slush pump 2 is embedded in the mud 6, influences the normal operation of slush pump 2, the workload of regularly clear mud is big, wasting time and energy has not only increased cost, but also has influenced working efficiency.

The patent No. is that CN200480005333.8 discloses a kind of Sewage treatment systems, and wherein waste water stream is divided into first mud and the waste water of sinking, and should also be dewatered to generate A level organic sludge by anaerobic digestion by just heavy mud.The drainage water that aerobic digests described drainage water and separates described digestion is to provide useless activated sludge.Should before forwarding hydrothermal treatment consists to, it in bi-level treatment, heat by useless activated sludge with vapo(u)r blasting and indirect steam.Increase the pH value of processed useless activated sludge then, and denitrogenation and reclaim ammonia salt.Low nitrogen stream with volatile lipid acid and soluble organic is separated then, and delivers to the aerobic digester.The biogas that generates during anaerobic digestion provides energy for heating useless activated sludge, is used for hydrothermal treatment consists, and suppresses to be somebody's turn to do just heavy mud from the heat heating of this hydrothermal treatment consists, is used to like hot anaerobic digestion.But this patent disclosure is to carry out sewage disposal by chemically treated method, and its cost height, use have its limitation.

The utility model content

At the above-mentioned liquidometer probe that exists in the prior art be wrapped easily, slush pump is blocked easily and the tail pipe of slush pump is buried the shortcoming that causes slush pump to damage easily, the purpose of this utility model provides a kind of sewage back pool antiplugging apparatus, this antiplugging apparatus is simple in structure, easy to use, not only can avoid the liquidometer probe to be wrapped, and can also guarantee the slush pump works better.

For achieving the above object, the utility model adopts following technical scheme:

This sewage back pool antiplugging apparatus comprises:

Separation net is arranged in the described sewage back pool, and is located at the probe top of liquidometer;

The mud mixing component further comprises pressurized air input tube, winding-up pipe, and the pressurized air input tube communicates with the winding-up pipe coupling, and the winding-up pipe is located at sewage back pool bottom, also is provided with injection hole on the winding-up pipe.

Described winding-up pipe is several, and every winding-up Guan Shangjun has several injection holes, and injection hole all is provided with downwards.

Described mud mixing component also comprises downtake, and downtake is along stretching in the described sewage back pool, and an end is connected with the pressurized air input tube and communicates, and the other end communicates with the pipe coupling of jetting.

In technique scheme, sewage back pool antiplugging apparatus of the present utility model comprises separation net and mud mixing component, and separation net is arranged in the sewage back pool, and is located at the probe top of liquidometer; The mud mixing component further comprises pressurized air input tube, winding-up pipe, and the pressurized air input tube communicates with the winding-up pipe coupling, and the winding-up pipe is located at sewage back pool bottom, also is provided with injection hole on the winding-up pipe.This antiplugging apparatus is isolated the floating refuse in the pond and liquidometer probe, slush pump tail pipe by separation net, prevent that the liquidometer probe is wrapped and the slush pump tail pipe is blocked, guaranteed that slush pump normally moves, reduced servicing time, avoid sewage to overflow contaminate environment, increased the work-ing life of slush pump.By mud mixing component winding-up pressurized air, prevent that silt from amassing silt and burying the slush pump tail pipe, thereby also guarantee the operating safety of slush pump, also need not periodic cleaning mud in addition, provide cost savings, improved working efficiency.
