The mode that the present invention adopts mechanical type cylinder barrel to push comes alternative existing diaphragm pump or peristaltic pump, and not only structure becomes compact, and efficiency have also been obtained great lifting; Feeding valve and discharge valve are separately positioned on cavity front end, and in distributing up and down, at feeding valve and discharge valve inside, ball sealer is set, due to the effect of ball sealer gravity, when piston is in suction, due to the effect of gas pressure, make to produce negative pressure in cavity, discharge valve ball sealer gravity adds the effect that negative pressure is adsorbed downwards, ball sealer can be adsorbed on discharge valve place firmly, and owing to producing negative pressure in cavity and atmospheric effect makes the ball sealer at feeding valve place upwards roll, and then material is made to suck in cavity by the effect of air pressure; When piston moves to cavity maximum value in cavity, material is filled with in cavity, because now piston is under the drive of driving mechanism, compress, now cavity needs outwards to get rid of material, feeding valve place is due to express material ball sealer, securely feeding valve can be sealed under making ball sealer add the effect of self gravitation, and discharge valve place ball sealer is under the pressure of material, make it break through the gravity of ball sealer, thus outwards get rid of material, when piston compression is emptying by material, then reenter suction, circulate successively.
The feeding valve adopted and discharge valve are same structure, and body cavity is spheroid shape structure, for feeding valve, when piston carries out suction, owing to producing negative pressure in cavity, barometric pressure then promotes ball sealer and moves upward, when barometric pressure deduct negative pressure value exceed gravity time, then ball sealer upwards rolls; And then make material enter feeding valve inner chamber, owing to being spheroid shape inner chamber, when ball sealer upwards rolls, material is made greatly easily to enter in cavity through ball sealer because intracavity space becomes, the ball sealer adopted is the steel ball that surface arranges polytetrafluorethylecoatings coatings, make it can not only prevent steel ball from getting rusty while guarantee weight and also can reduce the frictional force of ball sealer and material, make the ball sealer moment keep bright and clean, be not stained with glutinous material to ensure sealing effect; And teflon is set in body cavity makes it can ensure the smooth of inwall, prevent from being stained with glutinous material, it coordinates the effect that can ensure to seal with ball sealer.
Feeding valve and discharge valve valve body are spheroid shape, and its charging connecting tube and body cavity depart from its long axis centerline, can when charging, material departs from centre of sphere face to the thrust that ball sealer applies from ball sealer and applies, this mode of structure makes only to need less power that material just can be made to break through the sealing of ball sealer gravity when charging, but but do not affect ball sealer to seal the compressing of valve body, and this mode adds the fluency of material by valve, under the effect that ball sealer surface is rotated at ball sealer with body cavity surface of contact, keep in touch the clean of face, it is made to can be good at sealing when needs seal, avoid poorly sealed phenomenon, and can ensure not to be stained with glutinous material due to the characteristic of teflon, good lubrication and well toughness.
The driving mechanism adopted comprises drive motor, crank, flywheel and connecting rod, drive motor is connected with crank axle by V belt translation or Chain conveyer, and crank axle is connected with flywheel, the rotating speed of crank can be stablized, make connecting rod can be connected with crank rotate time easily through dead point, ensure the stability of system cloud gray model, when connecting rod is connected with piston simultaneously, be used as transition by crosshead, ensure that the stable of operation; In conjunction with the frequency variator in control mechanism, drive motor is controlled simultaneously, regulate the rotating speed of drive motor with this, and then the power of regulating system.
In this device, be provided with pressure transducer to detect the pressure in cavity, simultaneously flowmeter is set at feeding valve place, can cube amount of Real-Time Monitoring material loading, the material of some can be set, it is how many that material loading per hour also can be set, operates very easy; Arrange on the piston ring wear sensor can piston ring scuffing to a certain extent time, given the alarm by PLC, staff is reminded to change in time, adopt the form of three layers of piston ring, and carbon piston ring is set at middle part, it can lubricate to cavity inner wall the working life extending piston ring and cavity; The wear sensor adopted is conventional wear sensor, disconnects, and then cut off signal thus given the alarm when wearing up to a certain degree wire wearing and tearing wherein; Be arranged in carbon piston ring, because the carbon piston ring rate of wear is faster than stiff piston ring, make its can its wearing and tearing lose lubricity time, the safe and stable operation of give the alarm in time prompting changing carbon piston ring, assurance device.
The present invention adopts the form of twin-tub, respectively crank is arranged on flywheel both sides, and in 180 ° of angles between two cranks, can ensure to carry out material loading continuously, ensure that drive motor power is comprehensively used, avoid the loss of power consumption, this Placement can when a piston press simultaneously, another piston is in suction, the ball sealer of its discharge valve can not be made upwards to roll simultaneously, avoid the phenomenon that the power consumption that causes when two pistons extrude at the same time offsets, ensure that the effective power consumption of drive motor, it is made all to be applied in the conveying of material, it can be pooled together by the material of mixing tube by two cylinder bodies, thus realize conveying of making a concerted effort, material is delivered to fast and effectively the floor of needs.
