Description

Weight batch dosing units for weighing construction materials comprising a frame, an inlet funnel with a bolt, a weight measuring lever system. With a dial pointer with which a weigh bin having an upper cylindrical and lower conic part and an outlet bolt is associated are known.

The proposed metering device differs from the known ones in that it allows to increase the accuracy, increase the productivity and technological reliability of the dosing process for difficult-flowing materials.

This is achieved by the fact that the axis of the bunker is inclined to the vertical at an angle of up to 20 °, and one of its lower conical part is located vertically.

The drawing shows schematically a weighing batch doser for difficult-flowing materials.

It consists of a frame /, with a weight system 2 suspended from it and a dial indicator 5, a loading chute 4, with a trough-type inlet gate 5 fixed on it, driven by a pneumatic cylinder 6.

connected to the aforementioned lever system 2 by means of four hangers 9. The axis of the hopper with the vertical is up to 20 °. The cylindrical part of the hopper is adjacent to the conical circumference. Forming a lower conical part of the bunker, i.e. a truncated cone, is directed vertically. On the conical part 5 of the bunker, the exhaust glgvor 10 is fixed, similar to the inlet gate 5 of the tray type.

Powered weight portioning dispenser as follows.

When loading the metering unit, the inlet valve 5 using the pneumatic cylinder 6 completely opens the loading chute 4 and the material enters the weighing bin with a flow whose cross section is equal to the section of the loading chute 4. After the coarse weight is set, the valve 5 closes half (or two thirds) the section and the material continues to flow into weight bunker limited flow. The stopping of material loading is guaranteed due to the inclined position of the bottom of the shutter, and after the exact weight has been set, the shutter closes completely. When unloading hard-flowing material from the dispenser, the discharge valve 10 opens in such a way that.

the outflow of material along the vertical orazruyuschey a cone. Subsequent opening of the shutter 10 material expires through the entire discharge opening.

 Such a sequence provides different speeds of movement of the material along the walls of the bunker and prevents the possibility of free formation. In addition, the guaranteed outflow of material along the vertical wall breaks the line of operation of the roof, which also prevents the possibility of free-forming.

Subject invention

A weight portion dispenser for materials that are difficult to loose, contains an inlet funnel with a bolt, a weighing lever system with a dial gauge and a hopper with an exhaust bolt, characterized in that, in order to improve accuracy and increase productivity in it, the axis of the bunker is inclined by up to 20 ° to the vertical, and one of the lower conical parts forming it is located verticals.
