Description
Technical field
Water pump technology is the utility model is related to, it is especially a kind of to extract the diaphragm type water containing waste oil waste residue liquid
Pump.
Background technology
Industrial oily waste liquor, oil content is larger, and contained grease is various, including machine oil, hydraulic oil, lubricant grease, lubricating oil
Etc. multiple species.These oils value ratios are higher, there is higher reclamation value.But many solid-states in industrial wastes also be present
Waste, to extract these waste liquids bring difficulty.
Water pump on the market can about be divided into centrifugal water pump and volumetric water pump at present, and centrifugal water pump can not produce
Vacuum but it can be used for extraction and have more polymictic water, volumetric water pump can produce vacuum, but due to miscellaneous in liquid
Matter can wear mechanical part, and the life-span is low.
Utility model content
In view of this, it is necessary to for it is above-mentioned the problem of, there is provided a kind of diaphragm type water pump.
To achieve the above object, the utility model takes following technical scheme：
A kind of diaphragm type water pump, including pump chamber, be arranged in pump chamber flexible sheet, be connected to flexible sheet
Block and the rotary shaft of block can be driven, wherein the space that is formed with the pump chamber of the flexible sheet can be with
The movement of the block and change；
The pump chamber both ends are respectively arranged with entrance and exit, and are respectively arranged with entrance and exit unidirectional
Valve.
Further, it is provided with the pump chamber on the symmetrical two sets of elasticity in the pump chamber axis
Diaphragm, entrance and exit and the check valve being arranged in entrance and exit, wherein two sets of described flexible sheets each connect
At the both ends of the block.
Further, the rotary shaft leading portion is provided with eccentric shaft, and the eccentric shaft is correspondingly arranged with the block, eccentric
Axle can be by the convert rotational motion of motor into link stopper reciprocating motion.
Further, the flexible sheet is rubber diaphragm.
By motor driven rotary shaft, eccentric shaft driving block compression and stretching film；The space that diaphragm is formed with cavity
Volume change with the compression and stretching of block, the change of spatial volume produces the change of pressure, so as to by controlling phase
Waste liquid is extracted in the folding for the check valve answered；Because the utility model employs the compression of diaphragm and stretching instead of common positive displacement
The mechanical movement of water pump produces the change of pressure, overcome common volumetric water pump may not apply to extract it is useless containing impurity
The shortcomings that liquid, technological gap is filled up, improved the efficiency to liquid waste processing.

Embodiment
Further to illustrate that the utility model is to realize technological means and effect that predetermined purpose of utility model taken,
Below in conjunction with accompanying drawing and preferred embodiment, to according to specific embodiment of the present utility model, structure, feature and its effect, in detail
Carefully it is described as follows.
With reference to Fig. 1, the present embodiment provides a kind of diaphragm type water pump, including pump chamber, the bullet that is arranged in pump chamber
Property diaphragm 1, be connected to flexible sheet 1 block 4 and for drive block 4 move rotary shaft 3；Wherein described water pump chamber
It is provided with the neck 9 with flange week in vivo, the periphery of flexible sheet 1 is provided with dop with the level, the step point of the dop
Two-stage step is total to for big step and small stair, wherein big step is arranged on outside；The big step by with the flange clamping
So as to agree with the neck 9 so that the flexible sheet 1 combines with pump chamber sealing；
Further, the pump chamber both ends are respectively arranged with an entrance 5 and outlet 6, and entrance 5 is provided with entrance list
To valve 7, Outlet check valves 8 are provided with outlet 6；
Further, the leading portion of rotary shaft 3 is provided with off-centered eccentric shaft 2, the eccentric shaft 2 and the block
4 are correspondingly arranged；The wherein described centre position of block 4 is provided with a groove 10, wherein the eccentric shaft 2 is on the length direction of groove 10
Moving displacement be more than the length of groove 10, the eccentric shaft 2 moved left and right by block described in rotation forces 4.
During work, by motor driven rotary shaft 3, eccentric shaft 2 drives the compression of block 4 and tensile elasticity diaphragm 1；Work as bias
When axle 2 drives the extreme right in the arrival figure of block 4, the tensile elasticity diaphragm 1 of block 4, now flexible sheet 1 and cavity formation
The volume of working region 12 becomes big, and the pressure in working region 12 diminishes, and so as to which inlet one-way valve 7 is opened, liquid passes through entrance 5
Flexible sheet 1 is flowed into by inlet one-way valve 7 and in the working region 12 of cavity formation, then eccentric shaft 2 turns to block 4
During left end, the elasticity of compression diaphragm 1 of block 4, the spatial volume of working region 12 that now flexible sheet 1 is formed with cavity diminishes, work
Make pressure in region 12 and become big, so as to which Outlet check valves 8 are opened, liquid is from the working region that flexible sheet 1 and cavity are formed
Flowed out in 12 by Outlet check valves 8 outside outlet 6, it is achieved thereby that absorption and the discharge function of liquid；
More preferably, the diaphragm pump with double pump function is present embodiments provided, is provided with the pump chamber on institute
State symmetrical second flexible sheet 11 in pump chamber axis, second entrance 51, second outlet 61 and be arranged at second entrance
51 second entrance check valve 71, second outlet check valve 81 in second outlet 61 is arranged at, wherein the second described elastic membrane
Piece 11 is connected to the other end of the block 4.Operation principle with connected mode is same as described above no longer repeats；It may be noted that
It is that difference is：When eccentric shaft 2 drives block 4 to reach the extreme right in figure；Flexible sheet 1 is in extended state, and
Second flexible sheet 11 is in compressive state, when eccentric shaft 2 drives block 4 to reach the left end limit；Flexible sheet 1 is in
Compressive state, and second flexible sheet 11 is in extended state, it can be seen that the working region 121 of working region 12 and second
Working condition on the contrary, still the utility model make use of this nonsynchronous characteristic so that absorption and discharge to liquid be connect
Continue continual execution, saved the time, improved operating efficiency.
In more detail, the material of flexible sheet 1 is oil resistant rubber in the present embodiment.
Because the utility model employs the compression of diaphragm and stretching instead of the mechanical movement of common volumetric water pump and come
The change of pressure is produced, the shortcomings that common volumetric water pump may not apply to extract the waste liquid containing impurity is overcome, fills up
Technological gap, improve the efficiency to liquid waste processing.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
