Abstract
The utility model relates to a multifunctional squeegee pump, which is composed of a pump casing, a transmission shaft, a bearing, a rotary rack, pinch rollers, directive wheels, a rubber pipe and a rubber pipe supporting rack thereof. The two ends of the rotary rack is radially provided with the axial pinch rollers; another circumference of the rotary rack is provided with pairs of the directive wheels radially and separately; the part which enters the pump casing of the U-shaped rubber pipe is bent along the inner wall of the pump casing, and is spaced by the pairs of the directive wheels on the rotary rack. The pump, which has simple structure, low cost, high reliability, a plurality of functions and a long service life, can automatically suck or convey a plurality of flowing media, such as a mixture of liquid and solid, a mixture of liquid and gas, gas, high-viscosity liquid, etc. The utility model can also be used as a vacuum pump.
Description
The utility model relates to a kind of pump of transport flow material, particularly a kind of rubber pipe pump.
No matter existing pump class is driving type pump or positive displacement pump, its structure is all complicated, function is more single, the driving type centrifugal pump is discharged liquid by producing centrifugal force, has pump case, one to several impellers and guide vane, seal ring, Balance disc, positive displacement pump is used for the conveying of high-lift or liquid-solid mixture more, has cylinder body, cylinder sleeve, plunger, crawler shoe swash plate or linkage mechanism and sealing component, these member machining accuracy height, the cost height, sealing component in service is easy to wear, thereby causes leakage, produce mechanical failure, the parts of contact acid akaline liquid must adopt Stainless Steel Products or plastic article.
The purpose of this utility model is, a kind of simple in structure, not easy to wear, multi-functional sebific duct pump that cost is low is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of multi-functional sebific duct pump, it is characterized in that by pump case, transmission shaft and bearing thereof, swivel mount, pinch roller, upper saw pulley, sebific duct, the sebific duct support is formed, transmission shaft is positioned on the center line of cylindrical pump case, its Bearing Installation is in the pump case bi-side, swivel mount is fixed on the transmission shaft, by the transmission shaft driven rotary, swivel mount radially the two ends installation shaft to pinch roller, spaced radial is mounted to right upper saw pulley on another circumference of swivel mount, it is crooked and spacing by upper saw pulley paired on the swivel mount along the pump case inwall that " U " shape sebific duct enters the pump case part, fixedly connected with the sebific duct support on being fixed on pump case in the sebific duct two ends, the pinch roller outermost end to the distance of driving axle center greater than the crooked internal diameter of sebific duct and less than the crooked external diameter of sebific duct.
Sebific duct of the present utility model is equivalent to pump chamber, after transmission shaft is by motor deceleration during driven rotary, swivel mount rotates thereupon, axially the pinch roller of installing periodically turns round extruding to sebific duct in rotation, make sebific duct produce resiliently deformable, the part that sebific duct is crushed restores to the original state rapidly under the positive action of the paired upper saw pulley of recuperability and both sides of itself, in the pressurized sebific duct, produce vacuum space thus, can suck fluid from sebific duct one end, and pinch roller repeat under the extruding fluid is transferred out by the sebific duct the other end.
The utility model is simple in structure, can not produce leakage, does not need seal arrangement, requiring of component processing ratio of precision existing pump is low, and cost is low, adopts special sebific duct, have withstand voltage, wear-resisting, acid-proof alkaline, so rubber pipe pump reliability height, function is many, and using scope is wide, long service life, but self-priming or carry the medium of multiple flowability, for example liquid-solid mixture, liquid vapour mixture, gas, high viscosity liquid etc. also can be used as vacuum pump and use.The utility model also has the easy advantage of maintenance, and general only the needs changed sebific duct, and it is more convenient, quick more to change jobs.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model overall structure schematic representation.
Fig. 2 is the A-A cut-away view of Fig. 1.
Fig. 3 is the utility model pump case internal structure schematic perspective view.
As Fig. 1, Fig. 2 and shown in Figure 3, the multi-functional sebific duct pump of the utility model is by pump case 1, transmission shaft 2 and bearing 3 thereof, swivel mount 4, pinch roller 5, upper saw pulley 6, sebific duct 7, sebific duct support 8 is formed, transmission shaft 2 is positioned on the center line of cylindrical pump case 1, its bearing 3 is installed on the pump case bi-side, swivel mount 4 is fixed on the transmission shaft 2, by the transmission shaft driven rotary, swivel mount 4 radially the two ends installation shaft to pinch roller 5, spaced radial is mounted to right upper saw pulley 6 on another circumference of swivel mount 4, " U " shape sebific duct 7 enters the part of pump case 1 along pump case inwall bending and spacing by upper saw pulley paired on the swivel mount 46, fixedly connected with the sebific duct support 8 on being fixed on pump case in sebific duct 7 two ends, the pinch roller outermost end to the distance of driving axle center greater than the crooked internal diameter of sebific duct and less than the crooked external diameter of sebific duct.
In embodiment as shown in the figure, spaced radial is installed 4 pairs of upper saw pulleys on the swivel mount 4.
