Description
Technical field
The present invention relates to a kind of annex of sewage pump, particularly a kind of sewage pump water diversion apparatus without stopping up.
Background technique
The processing of waste water, holding back of its dirt is the link can not be ignored, although be equipped with the twice grid at the Sewage Disposal regulating tank as last, but still have a considerable amount of fiber fines and enter regulating tank.A lot of sewage is alkalescence, and sewage is after the pump lifting enters pipeline, and fiber is attached to inner-walls of duct with the alkali dirt, causes the discharge of sewage day by day to decay, and have to remove piecemeal pipeline when serious and be cleared up.For a large amount of dirts and the fiber that contain in sewage, grid is difficult to fiber fines is carried out to effectively catching, and the selection of sewage lifting method is most important for the reliable operation of sewage plant.
Pump for sewage promotes, and generally in the suction inlet pipe lower end of pump, bottom valve is installed.Due to the existence of dirt in water, bottom valve can't normally open and close in actual use, and sewage plant also just can not normal operation.
For solving traditional bottom valve, can not on market, occur adopting without stopping up submerged pump for the problem of sewage pump, this pump can be carried little foreign material with current.But it can not solve the problem that the fouling of mouth piece inner-walls of duct or fiber adhere to, and the pump housing is very under water strong in corrosivity for a long time, rate of fault is inevitable very high.Once and break down, the pump housing will together be pulled out with the top pipeline in pond, not only workload is large, and can cause sewage plant to stop transport for a long time, thereby brings impact to normal production.
Summary of the invention
The object of the invention is to, overcome problems of the prior art, a kind of sewage pump water diversion apparatus without stopping up is provided, can make sewage pump start rapidly, reliable operation, and be convenient to clear up dirt.
For solving above technical problem, a kind of sewage pump water diversion apparatus without stopping up provided by the present invention, comprise tank body and suction sleeve, described tank body is positioned at the top in pond, the upper-end surface of described tank body is provided with reduced diameter section, the upper-end surface of described reduced diameter section is provided with the flange end cap, and water-feeding valve and relief valve are installed on the circumference of described reduced diameter section, and the position of described water-feeding valve is higher than described relief valve; The lower end of described suction sleeve is inserted in the bottom in described pond, and the upper end of described suction sleeve is inserted in described tank body until described reduced diameter section, and its upper end-hole height is between described water-feeding valve and described relief valve.
Sewage pump is first opened inlet valve and relief valve to the water diversion tank water filling before starting, and with the injected water water level, raises gradually by the Bas Discharged in tank body and the pump housing, when relief valve there are flowing out, inlet valve and relief valve is closed.The water storage of suction water diversion tank after pump startup, after making liquid level decline reach certain negative pressure, constantly aspirate up the water under suction sleeve, enters the sewage pump intake pipe, thereby guarantee the normal operation of water pump.The dirt cleaning of suction sleeve inwall, can open the flange end cap, with special tool, from the upper end-hole of suction sleeve, inserts, and directly the suction sleeve inwall carried out to the mechanical removal dirt.
As improvement of the present invention, the suction sleeve in described tank body is covered with filter screen.The dirt of filter screen in can effectively catching sewage, reduced the cleaning work amount greatly, and sewage plant can be moved steadily in the long term under design discharge.
As a further improvement on the present invention, described filter screen is the stainless steel cylinder, is densely covered with the aperture that diameter is 4mm on described cylindrical wall, and the upper end-hole of described cylinder, by filter screen capping sealing, is welded with handle in described filter screen capping.During the cleaning filter screen, can, by handle by outside the whole extraction of filter screen tank body, after cleaning out outside, reload.
As another improvement of the present invention, the lower circumference of described tank body is provided with hand hole, and described hand hole place is provided with the hand hole end cap.Regularly open hand hole, can clear up easily the dirt that is trapped in tank base.
The accompanying drawing explanation
Fig. 1 is the structural representation of the present invention without the sewage pump water diversion apparatus stopped up.
In figure: 1 filter screen, the capping of 1a filter screen, 1b handle, 2 tank bodies, 3 water-feeding valves, 4 flange cappings, 5 relief valves, 6 suction sleeves, 7 pump inlet pipes.
Embodiment
As shown in Figure 1, the sewage pump water diversion apparatus without stopping up of the present invention, comprise tank body 2 and suction sleeve 6, and tank body 2 is positioned at the top in pond, and the lower circumference of tank body 2 is provided with hand hole, and the hand hole place is provided with the hand hole end cap.The upper-end surface of tank body 2 is provided with reduced diameter section, and the upper-end surface of reduced diameter section is provided with flange capping 4.Reduced diameter section had both reduced the air volume of suction sleeve 6 tops, had reduced again the dismantlement work amount, had dwindled the leakage circumference simultaneously.Water-feeding valve 3 and outlet valve 5 are installed on the circumference of reduced diameter section, and the position of water-feeding valve 3 is higher than outlet valve 5; The lower end of suction sleeve 6 is inserted in the bottom in pond, and the upper end of suction sleeve 6 is inserted in tank body 2 until reduced diameter section, and its upper end-hole height is between water-feeding valve 3 and outlet valve 5.Suction sleeve 6 in tank body 2 is covered with filter screen 1, and filter screen 1 adopts Stainless Sheet Steel to be rolled into cylinder, is densely covered with the aperture that diameter is 4mm on cylindrical wall, and the upper end-hole of cylinder, by filter screen capping 1a sealing, is welded with handle 1b on filter screen capping 1a.
Sewage pump is first opened inlet valve and relief valve to the water diversion tank water filling before starting, and with the injected water water level, raises gradually by the Bas Discharged in tank body 2 and the pump housing, when relief valve there are flowing out, inlet valve and relief valve is closed.The water storage of suction water diversion tank after pump startup, after making liquid level decline reach certain negative pressure, constantly aspirate up the water under suction sleeve 6, after filter screen is held back dirt, enters the sewage pump intake pipe, thereby guarantee the normal operation of water pump.
The dirt cleaning of suction sleeve 6 inwalls, can open flange capping 4, with special tool, from the upper end-hole of suction sleeve 6, inserts, and directly the suction sleeve inwall carried out to the mechanical removal dirt.During the cleaning filter screen, can, by handle 1b by outside the whole extraction of filter screen tank body 2, after cleaning out outside, reload.
