Abstract
The utility model discloses a kind of water pump without bottom valve filter, include filter body, described filter body is located on the raised platform around a well of water pump, be made up of filter box and screen pack, described filter box is combined by suction hose and companion flange dish and is made, filter box inside is provided with a screen pack, is provided with sewage draining exit, sewage draining exit is provided with detachable end on screen pack top.Filter moves to raised platform around a well by the utility model below suction hose in absorbing well, absorption well, excavating the lifting operation link decreasing water pipe in water-pipe blockage thing process, only the end cap need opened above filter can excavate tamper, only need a people just can operate, it is safer, convenient to operate, and the man-hour of input also reduces greatly, save manpower and materials, improve production efficiency, also improve safety coefficient, the personnel that avoid cause danger in lifting process.
Description
Technical field
The utility model belongs to sewage water filtration facility field, specifically relates to a kind of water pump without bottom valve filter.
Background technology
Water pump filter is generally be used in pump sump mouth, for preventing impurity from entering water pump, with a device of anti-tamper water pump accessory.In the operational area that the operating environments such as colliery are severe, complicated, water source in pump house sump is mainly from the mine water (containing more impurity) of working face, although before inflow sump, water source is by way of some filters, and it is more, extremely stagnant that the water flowed in sump still floats thing.In order to avoid more dirt in the process of main drain pump draining, impurity enters main drain pump, comparatively galling is produced to water pump, usually can without bottom valve pump strainer be installed in absorbing well, absorption well, and filter screen is hemisphere planar, rectangle cylindrical void filtered version, but this filter is directed to some as wooden contract, fragment class filter effect is not good, in addition, the maximum drawback of this filter is: by the restriction of installation site, when after this plugged filter, when needing cleaning foreign material, pipeline lifting operation must be carried out, this operation process needs the input of a large amount of personnel, the input in a large amount of man-hour and in operation process safety coefficient low, it is many unfavorable to bring to attended operation, if but clear up the suction line bottom valve filter of obstruction not in time, pumping drainage resistance can be caused again to increase, drainage efficiency declines, slightly larger foreign material easily enter in pump body and increase impeller coefficient of friction, correspondingly reduce water pump service life, affect the progress of work.
Summary of the invention
The utility model solves the deficiencies in the prior art, provide a kind ofly to use manpower and material resources sparingly, water pump without bottom valve filter that operating safety factor is high.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of water pump without bottom valve filter, include filter body, it is characterized in that, described filter body is located on the raised platform around a well of water pump, be made up of filter box and screen pack, described filter box is combined by suction hose and companion flange dish and is made, and filter box inside is provided with a screen pack, be provided with sewage draining exit on screen pack top, sewage draining exit is provided with detachable end.
Preferably, the suction hose on described filter box is managed by DN200 and DN250 pipe forms.
Preferably, described screen pack is the steel plate of thickness 5mm, and surface of steel plate has been uniformly distributed the circular hole that several diameters are 16mm.
Preferably, described end cap is connected by screw, nut with between filter box.
Filter moves to raised platform around a well by the utility model below suction hose in absorbing well, absorption well, excavating the lifting operation link decreasing water pipe in water-pipe blockage thing process, only the end cap need opened above filter can excavate tamper, only need a people just can operate, it is safer, convenient to operate, the man-hour of dropping into also reduces greatly, saves manpower and materials, improves production efficiency; The arrangement increases safety coefficient simultaneously, the personnel that avoid cause danger in lifting process, substantially potential safety hazard can not be there is, and this screen pack is dismountable, if this screen pack finds seriously corroded, is out of shape the phenomenons such as serious, to such an extent as to when cannot normally use, can simply along ring flange dismounting and change.
Screen pack in the utility model is the steel plate of thickness 5mm, surface of steel plate has been uniformly distributed the circular hole that several diameters are 16mm, this filter structure top cap device more in the past, the filter effect in hole is better, can the foreign material of effective filter diameter 16mm, greatly reduce the loss to water pump, improve the water pump operation cycle.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.

Wherein, in figure: 1-raised platform around a well; 2-screen pack; 3-suction hose; 4-ring flange; 5-sewage draining exit; 6-end cap.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model embodiment discloses a kind of water pump without bottom valve filter, as shown in Figure 1, include filter body, described filter body is located on the raised platform around a well 1 of water pump, be made up of filter box and screen pack 2, described filter box is combined by suction hose 3 and companion flange dish 4 and is made, and filter box inside is provided with a screen pack 2, be provided with sewage draining exit 5 on screen pack 2 top, sewage draining exit 5 be provided with detachable end 6.Filter moves to raised platform around a well 1 by the utility model below suction hose in absorbing well, absorption well, reinstalled to be fixed on horizontal pipeline and docked with water pump, and be provided with sewage draining exit 5 on screen pack 2 top, so only need staff can open the end cap 6 above sewage draining exit 5, by clear for the tamper in water pipe, eliminates the lifting operation link of water pipe, it is safer, convenient to operate, consuming time also shorter, improve the safety coefficient of staff, the personnel of avoiding lift by crane danger.
In order to further prioritization scheme, as shown in Figure 2, screen pack 2 described in the utility model is the steel plate of thickness 5mm, surface of steel plate has been uniformly distributed the circular hole that several diameters are 16mm, the filter effect of the circular pore structure of this screen pack 2 is better, well decreases the wearing and tearing of main drain pump, improves the water pump operation cycle, screen pack thickness and these data of Circularhole diameter also depending on the concrete condition of environment, can not fixed in addition.
In order to further prioritization scheme, suction hose 3 on the utility model filter box is managed by DN200 and DN250 pipe forms, the material of suction hose also can depending on the concrete condition of environment, end cap 6 is connected by screw, nut with between filter box, facility, cheap chosen by these materials, met the principle of cost efficiency in producing.
Concrete making step of the present utility model is:
A. get DN200 pipe and DN250 pipe and companion flange dish 4 combination and make filter box as shown in Figure 1.
B. get the steel plate of thickness 5mm, evenly get the circular hole that several diameters are 16mm above, steel plate is made sizeable circular mounting in filter box.
C. whole filter to be fixed on request on horizontal pipeline and to connect with water pump.
Transformation of the present utility model meets the efficient principle of mine safety, also meets the principle of cost efficiency, is worth other drainage systems to use for reference application, has certain promotional value.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
