Description

 :,:. Device for dispensing bulk products

(options)

The proposed utility model relates to technological equipment and may find application in the food industry, medicine, etc.

A metering device is known comprising a shchishndr, within which a piston is located, and a drive. The device is equipped with a rotary valve connecting the cylinder cavity through the end hole with either the inlet or outlet pipe III.

A metering device is known comprising a hopper, within which a piston is located, and a drive. The hopper is equipped with two holes for piston inlet and product outlet, located coaxially / 2 / (prototype).

The disadvantage of this dosing device is the ability to push part of the bulk product back into the hopper.

The technical result that can be achieved using the proposed device is to eliminate the phenomenon of pushing part of the dose of the product back into the hopper, increasing the accuracy and productivity of dosing.

The technical result is achieved due to the fact that the dosing device for products, which contains a hopper, a piston and

the drive is provided with a cylinder with at least one hole in the upper part for product inlet, the edge of the hole being on

distance from the end hole of the cylinder, which serves to

product yield, where D is the diameter of the cylinder, q) is the angle of repose of the bulk product.

The elimination of the phenomenon of pushing the product back into the hopper is achieved due to the possibility of using a cylinder with holes of such a size that excludes the pushing of part of the product back into the hopper.

1 and FIG. 2 are presented possible options for the implementation of a device for dispensing bulk products.

The device consists of a hopper 1, cylinder 2, located horizontally, inside of which a piston 3 is mounted. Piston 1 is driven by any drive mechanism (not shown in Fig.). The cylinder 2 has an inlet in the upper part 4 and an outlet end hole 5. The piston is also equipped with a device for regulating the stroke of the piston 6.

A device for controlling the stroke of the piston 6 allows you to set and change the volume of dosing.

The device operates as follows:

When the piston 3 moves to the left, the internal volume of the cylinder 2 is freed and a working volume is formed, limited by the internal surface of the cylinder 2, spoiled 3 and the natural slope of the bulk product 7. Through the inlet 4, the bulk volume is filled with the bulk product.

When the piston 3 reaches the device for controlling the stroke of the piston 6, the measurement of the dose of the product ends.

To exit the dose of the product, the piston 3 moves to the right and displaces the product through the end hole 5 of the cylinder 2 into the container ...

The displacement occurs until the piston reaches the end hole 5.

Next, the cycle repeats.

A variant of the device for dispensing bulk products (Fig. 2), which consists of the same elements as the above device, characterized in that the cylinder 2 is installed at an angle a to the horizontal and is equipped with a swivel joint 8 with a locking bracket for turning. This version of the device allows you to dispense bulk products characterized by small angles of repose (30 °).

The technical result that can be achieved using the proposed device is to eliminate the phenomenon of pushing part of the dose of the product back into the hopper, increasing the accuracy and productivity of dosing.

The technical result is achieved due to the fact that the dosing device for bulk products, which contains a hopper, a piston and a drive, is equipped with a cylinder with at least one hole in the upper part for the inlet of the product, and the cylinder is installed at an angle

and to the horizon, and the edge of the hole is at a distance L -, g from

the end hole of the cylinder used to exit the product, where D is the diameter of the cylinder, is the angle of natural inclination of the bulk product, and the angle of inclination of the cylinder 2 to the horizontal.

The elimination of the phenomenon of pushing u) of the product back into the hopper is achieved due to the possibility of using a cylinder with openings of such a size that excludes the pushing of part of the product back into the hopper.

The presence of a rotary 8 with a rotation angle lock allows you to change the angle of inclination of the cylinder 2 to the horizon and to dose products characterized by a slope less than the calculated one, as well as to increase the accuracy of dosing.

The device works similarly to the above.

This device has been tested at the Department of Food Technological and Production Technologies of St. Petersburg State University of Low-Temperature and Food Technologies and can find
