Description

Wriggle pump

The utility model relates to a kind of peristaltic pump.

Peristaltic pump is a kind of new pump of the development and production in recent years after gear pump, plunger pump, wing pump etc.At present be useful on large-scale peristaltic pump on the cementing truck in China, function is few; The peristaltic pump function that also has is more, but power is too little, and is only limited to the sleeve pipe that uses a kind of size, so be restricted on using scope, structure is not compact, dangerous, poor reliability.

In view of above reason, the purpose of this utility model be for a kind of compact structure be provided, adjust that using scope is wide, the peristaltic pump of good reliability, safety.

The pump housing that contains import and outlet is arranged in the utility model, be loaded on the front and back panel of pump housing front end and back end, be positioned at the pump housing and two ends and be contained in main shaft on the front and back panel, place the pump cover on the pump housing, it is characterized in that having in the pump housing driving mechanisms that contain at least three rollers that rotate with main shaft, on pump cover one end, the connection axis hole is arranged, joining shaft passes the connection axis hole on front and back panel and the pump cover on the pump housing successively and pump cover is connected and rotatable with the pump housing, the pump cover inwall is an arc-shaped bend, formed passage between pump cover inwall and pump housing import and outlet and driving mechanism, at the pump housing import and export band tooth pipe clamp is housed respectively, the guide rail locking apparatus of distance between can regulate driving mechanism that cooperates with pipe clamp and pump cover, on the other end of pump cover, be equipped with the spacing regulator that the can regulate pump cover slides up and down (referring to Fig. 1, Fig. 9, Figure 10).

The lock pad that contains the tooth that matches with the pipe clamp tooth, spring housing in the locking hole that is contained on the pump housing are arranged in the above-mentioned guide rail locking apparatus, axostylus axostyle one end stretches in the hole on spring housing and the lock pad and is connected on the lock pad, spring is contained on the axostylus axostyle, axostylus axostyle stretches out the spring housing the other end and tightens rotating pipe clamp controlling rod (referring to Fig. 7, Fig. 9) is housed, regulate the upper-lower position of pipe clamp, just can under the situation of renewal part not, satisfy the caliber silicone tube of multiple different size.

Have in the above-mentioned regulator and pass pump cover and be threaded in bolt on the pump housing, but slide relative between pump cover and bolt, spring seat passes bolt and is fixed on the pump cover, swivel nut is threaded in the top of bolt, the spring (referring to Figure 10) that is contained on the bolt is arranged between spring seat and swivel nut, play spacing bumper and absorbing shock effect, the elastic force of Adjusting bolt Adjusting screw adjustable springs is to regulate sliding up and down of pump cover.

In the connection axis hole on the above-mentioned pump cover eccentric bushing is housed, joining shaft passes eccentric bushing (referring to Fig. 4), and rotating eccentric sleeve just can be applicable to the silicone tube of at least two kinds of different wall under the situation of not opening pump cover in the position that connects axis hole.

On the above-mentioned main shaft active oblique gear is housed, the driven helical gear (referring to Fig. 2) that meshes with active oblique gear is arranged on the roller in the driving mechanism, adopt the helical gear transmission, transmitting torque is big.

Roller in the above-mentioned driving mechanism is four (referring to Fig. 1), and running steadily.

On above-mentioned main shaft one end connection slot is arranged, connecting hole (referring to Fig. 1, Fig. 3) is arranged on pump housing front panel, can be connected in series many pumps, increase work efficiency.

During work, at first move the pipe clamp controlling rod, pipe clamp is upwards carried, will be imported and exported us and open, again regulator is backed out, with the joining shaft is that pump cover has been removed in the axle center, lay the flexible silicon sebific duct along pump housing internal channel, silicone tube stretches out defeated, the receptacle (Elastic Contact) of outer each self-closing of two ends of pump, puts down pump cover, and by the adjusting of the bolt in regulator pump cover position, this position is the position that different tube diameters can both adapt to.If when changing the silicone tube of different wall, only eccentric bushing is rotated to an angle (180 °), at last pipe clamp is put down and pins and the two ends of silicone tube are clamped it can not be rotated.Because the two ends of pipe clamp all are teeth, so the degree of tightness of folder is adjustable.

During the utility model work, main shaft rotates first roller that drives in the driving mechanism makes the flexible silicon sebific duct be closed condition, when one section flexible silicon sebific duct recovers its original form, liquid is sucked from entry end, the liquid of this part is rolled by second roller subsequently, final liquid is released from pump discharge, enters in the receptacle ...

Compare with existing peristaltic pump, the utlity model has following advantage:

1, compact structure, a tractor serves several purposes satisfies the caliber of multiple different size under the situation of renewal part not, the silicone tube of different wall, adjustment range is wide, safety.

2, be with helical gear roller to revolve round the sun, and produce rotation when being obstructed, so work the time is rolled all the time when contacting with silicone tube with main shaft.Owing to be to roll just to reduce friction,, improved the working life of roller and silicone tube so reduced wearing and tearing;

3, power is big, can be connected in series high working efficiency by two pumps;

4, applied widely, can be widely used in the stronger liquid of easy pollution and corrosivity, as beverage packing, food processing, Chemical Manufacture, pharmacy, industries such as blood product.
