Description

Birotor peristaltic pump

Technical field

The utility model is related to peristaltic pumps, are exactly specifically the improved structure of hose pump rotor.

Background technology

Peristaltic pump in the prior art is widely used in the industrial circles such as chemical industry, and basic structure includes shell and is placed in shell Internal hose drives roller, that is, rotor squish hose come pumped medium by the rotor field spider of main shaft drives rotation.Existing structure In, the stage casing of main shaft is by bearing support on shell, and both ends wherein one end of main shaft is connected with driving mechanism, the other end connect and turns Son is single-turn minor structure, and structure defect outstanding is exactly that efficiency is low, just needs a large amount of time to pump a large amount of media, Also it is exactly that must provide other set equipment to pump different media, the equipment investment of production is beaten.

Utility model content

The purpose of this utility model is to provide a kind of birotor peristaltic pump that pumping efficiency is high, can both pump homogenous medium Foreign medium can also be pumped.

To achieve the above object, the utility model uses following technical scheme：

A kind of birotor hose pump rotor, the roller on rotor constitute roll-in cooperation with hose, and the both ends of main shaft are respectively connected with One rotor, the main shaft between two rotors are connected with driving mechanism, and the main shaft axle body between rotor and driving mechanism is by axis It holds and is supported on casing, each rotor pairing is provided with hose.

By adopting the above-described technical solution, by being provided with two rotors and being equipped with respective hose for it, so One equipment has the pumping task that two groups of pumping units respectively complete itself, it is clear that the working efficiency of peristaltic pump is substantially increased, Simultaneously only there are one transmission mechanism and the effect of only need a motor that two single lobe pumps of the prior art can be realized, undoubtedly Equipment investment is significantly saved, in addition, the main shaft between two rotors is connected with driving mechanism, can be substantially reduced in this way The volume of equipment, facilitates in-site installation.

Specific implementation mode

It is described in further detail with reference to Fig. 1 to 7 pairs of the utility model.

In conjunction with Fig. 3,5, a kind of birotor peristaltic pump, the roller 21 on rotor 20 constitutes roll-in cooperation, main shaft with hose 70 10 both ends respectively connect there are one rotor 20, and the main shaft 10 between two rotors 20 is connected with driving mechanism, rotor 20 and driving For 10 axle body of main shaft between mechanism by bearing support on casing, the pairing of each rotor 20 is provided with hose 70.

In said program, the both ends of main shaft 10 are used for connecting rotor 20, and the roller 21 on rotor 20 constitutes suitable with hose 70 Degree compresses, and rotor 20 is servo-actuated when main shaft 10 rotates, 21 roll-in hose pumped medium of roller.The utility model is characterized by Power is connected on main shaft 10 between two rotors 20, i.e. power accesses at the middle part of main shaft 10, so that a main shaft 10 Drive two rotor 20 while stress it is more reasonable, avoid it from being acted on by single moment of flexure so that the bearing of main shaft 10 by Power is more reasonable, extends the service life of equipment, necessarily substantially reduces maintenance cost and maintenance downtime.

The transmission mechanism that the driving mechanism is intermeshing turbine 30, worm screw 40 is constituted, main shaft 10 and turbine 30 Central coaxial is connected.It selects turbine and worm mechanism to solve throttling problem as transmission mechanism, the length of main shaft 10 can be effectively reduced Degree is worth the volume of complete machine to greatly reduce.

The transmission mechanism of the turbine 30, the composition of worm screw 40 is placed in reducer shell 50, and reducer shell 50 is by two The 51 basin mouth of half-shell of a peviform is opposite to be enclosed, and is had hole 511 to install bearing in the middle part of the end plate of half-shell 51 and is used for supporting spindle 10. The structure type for using a halfbody, not only improves turbine 30, worm screw 40, is more advantageous to the arrangement of main shaft 10, while also having outer The hose 70 in portion arranges reserved space.

Hose shield 60, hose shield 60 and the two of reducer shell 50 are provided on the outside of the two end plates of reducer shell 50 Annular groove 61 is enclosed on the outside of end plate and constitutes tube seat, hose 70 is placed in annular groove 61, and the pipe end of hose 70 is from annular groove It is drawn at 61 slot end, main shaft 10 extends in the vallecular cavity of hose shield 60 and is connected with rotor 20.Said program can be seen that Reducer shell 50 is used effectively the composition part as flexible pipe groove, i.e., a hose shield is added outside reducer shell 50 Cover 60 just forms the tube seat of constraint hose.

Specific connection type can also become extremely simple, and hose shield 60 as mentioned includes the coaming plate for constituting slot bottom, Built-in, external annular flange 63,62, built-in annular flange 63 and 51 phase of half-shell are respectively arranged in its interior outer side edges Even.

Due to the dual-rotor structure of use, in fact peristaltic pump industry provided by the utility model is it can be understood that be one multiple Pump is closed, two hose can also pump heterogeneous medium, may be selected by described two in this way it is of course possible to pump homogenous medium The setting of hose 70 same position is in the same direction, at the incorgruous position of dystopy, to meet the objective demand of production scene.
