About WITH

The invention relates to the field of composting, peristaltic pumps and can be used in various sectors of the national economy for pumping fluids.

The aim of the invention is to simplify the design of the pump.

Figure 1 shows the constructive scheme of the pump in the off position; figure 2 - the same. view in working position; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 2.

The pump includes a housing 1, an elastic pump tube 2 placed therein, pinch rollers 3 interacting with tube 2 and mounted on a yoke 4 placed on the rotor 5 with the possibility of relative radial movement, and an eccentric drive 6 mounted on the drive shaft 7. Rotor 5 mounted on the shaft 7 with the possibility of relative rotation and provided with a radial groove 8, and the rocker arm 4 with the rollers 3 is installed in this groove 8 with the possibility of relative movement and interaction with the eccentric drive 6, and the rotor 5 and the yoke 4 are mutually spring-loaded springs 9. Between the rollers 3 and the tube 2, an elastic casing 10 is installed. The yoke has support rollers 11.

In the initial (inoperative) position of the pump, the rocker 4 with the rollers 3 is under the action of the springs 9, the elastic forces of the casing 10 and the pump tube 2 is displaced to the pump axis, and the pump tube 2 is in a free state along its entire length.

When the pump is turned on, the eccentric drive 6 rotates together with the shaft 7, through the support rollers 11 acts on the rocker arm 4, moving it in the slot 8 of the rotor 5 towards the tube 2, and the pinch rollers 3 compress the elastic tube 2 through the sleeve 10. After that, the rollers 3 move on the holder 10, successively clamping the pump tube 2 and moving the pumped medium through it.

After turning off the pump, the rocker arm 4 with the rollers 3 under the action of the springs 9, the elastic forces of the casing 10 and the pump tube 2 return to their original position and unload the pump tube 2.

Thus, it is constructively simply to automatically unload the pump tube 2.

Claims (1)

Invention Formula A peristaltic pump comprising a housing, an elastic pump tube housed therein, pinch rollers cooperating with the tube and mounted on a rocker arm positioned on the rotor with the possibility of relative radial movement, and an eccentric drive mounted on the drive shaft, characterized in that, in order to simplify structure, the rotor is mounted on the shaft with the possibility of relative rotation and provided with a radial groove, and the rocker arm with rollers is installed in this groove with the possibility of relative movement and interacting with an eccentric drive, with the rotor and rocker mutually spring-loaded.
