Abstract

Use: dosing of bulk materials in the food, chemical and other sectors of the national household. The invention of the bulk material flows from the hopper 2 into the bucket 6, the elastic sensor element 3 is deformed, the information about which is fed to the control unit 5. When the plate 10 rotates, the suspended bulk material 1 is divided into several equal parts, which through pipes 13 are fed into containers 15. 1 sludge.

Description

This invention relates to the dosing of bulk materials.

Volumetric methods for dispensing bulk materials are widely known. 1 Dispensing with volume dispensers. Inconsistency in the specific gravity of the product being metered influences both the accuracy and the nominal value of the dose.

A technical solution is known, which is peculiar to the fact that some doses are supplied for return 2. However, in the case of small doses, due to the inconsistency of the specific mass of the product being metered, both the accuracy and the performance of the dosage

The aim of the invention is to improve the accuracy of dosing.

The goal is achieved by dosing bulk materials in a manner involving the formation of volumetric doses, before volumetric dosing, bulk material is measured in an amount whose mass is equal to the total mass of volume doses. The goal is also achieved by the device for dosing bulk materials, containing a body, vibrator. with a weight capacity located underneath, a sensitive element with a weight dose sensor, an unloading mechanism and a control unit, fitted coaxially with the weight with a guide tube and a centrifugal plate feeder with measured containers placed around it, and the weighing container has a volume not less than the sum of the volumes of measuring containers. This makes it possible to increase the accuracy of dosing, because equal parts and the amount of material that, when the vibrating feeder of the weighing dispenser is turned off, is in the space between the bucket and the vibratory feeder. Since the accuracy of dosing largely depends on the amount of this material, the section of this material, with its effect on dosing accuracy, is especially sensitive.

The drawing shows the dispenser

The bulk materials dispenser comprises a housing 1, in the upper part of which there is a weighing dispenser consisting of a hopper 2, an elastic sensing element 3 with a strain gauge 4 connected to the control unit 5. A bucket 6 is mounted at the free end of the elastic sensing element 3. At the bucket 6, an unloading mechanism 7 is installed on the body and communicates with the control unit 5. Above the bucket 6, a vibrating feeder 8 is installed, the drive 9 of which is connected to the control unit 5. In the lower part of the housing 1 there is a weighted dose separator consisting of a plate 10 mounted on the axis of the engine 11, and evenly mounted on the housing 1 of the plastic bulk material into several pieces. The number of plates 12 determines the number of parts of the division of the weighted dose. At the edge of the plate. The guide tubes 13 are installed for the flow of the divided material. A tube 14 is installed on the body of the tube 14. Under the tubes 13 there are tanks 15 for the divided material.

The device works as follows.

When the device is turned on, the plate 0, mounted on the axis of the engine 1 i, begins to rotate. The control unit 5 includes the drive 9 of the vibrating feeder 8, and the bulk material from the hopper 2 enters the bucket 6. The elastic sensor element 3 is deformed. Information about the amount of deformation of the elastic sensor element 3 by means of the anti-vibration sensor 4 occurs in the control unit 5 granular product in the bucket 6 reaches the installed, the control unit

turns off the drive 9 of the vibrating feeder 8 and turns on the mechanism 7 unloading. Suspended bulk material passes through pipe 14 onto rotating plate 10. During rotation

plates 10 suspended bulk material 1 is divided into several equal parts (the number of these parts depends on the number of evenly placed plates 12). The portions of the separated material through pipes 13 enter containers 15. Then the cycle repeats.

Using the proposed method of dosing bulk materials and the design of the dispenser allows, as compared with

5 existing to reduce the impact on the accuracy of the material, which is in the space between the weighing capacity of the weighing device and the feeder, and thereby increase the accuracy of dosage
