Abstract

The invention relates to lifting, but transport engineering, namely to screw conveyors for transporting bulk materials, and Used in various industries. The goal is to ensure uninterrupted uniform quality of the material during batch feeding of the material. Under the loading nozzle 4 there is installed a measured capacity, made with an adjustable volume. In case I with screw 2 outside the measuring container, additional screws are placed, the axes of which are parallel to screw 2 and are located in the same plane with it. The screw 2 is made of two adjacent parts, one of which is located in the measuring container and has a smaller diameter. At regular intervals, the material is fed through the loading nozzle 4 into the measuring container. Further, the material is captured by a screw 2 with a smaller diameter and moves to the discharge pipe 5 with part 2 with a larger diameter. The excess material is poured onto additional screws, which also feed the material to screw 2 in the direction of pipe 5. 1 a.p. f-ly, 3 ill. § о: с

srig.1

The invention relates to a hoisting machine industry, namely to screw conveyors for transporting bulk materials, and can be used in various industries.

The purpose of the invention is to provide a continuous, uniform dispensing of the material during the batch feeding of the material into the screw feeder.

Figure 1 - shows a screw feeder, a general view in longitudinal section; FIG. 2 is a section A-A in FIG. in fig. 3 is a section bB in figure 1,

The screw feeder consists of the housing 1 with the screw 2 of the receiving chamber 3, the loading 4 and the unloading 5 nozzles and the drive 6 placed in it. Under the loading nozzle 4 there is a measuring tank 7 fixed with two threaded rods 8. on the receiving chamber 3. In case 1, outside the measured capacity 7, additional screws 9 are placed, the axes of which are parallel and located in the same plane with the main screw 2, which is made of two adjoining chateys, one of which has a smaller diameter and is located in the measuring capacity 7. The latter is made with an adjustable volume by moving the upper movable part of the capacity-takeoff 4 and further into the measuring capacity 6. In the measuring capacity 7, the material is gripped by the main screw 2 with a smaller diameter

meter and moves further to the discharge pipe 5 with another part of the screw 2 with a large diameter. A small excess of material is poured from the measuring tank 7 to the additional screws 9, which also feed the material to the main screw 2 in the direction of the discharge port 5. The invention allows to supply equal portions of the material to the measuring tank containing one portion of the material without accumulating it in the receiving chamber.

Claims (1)

1. A screw feeder, including a housing with a screw, a receiving chamber, loading and unloading pipes and a drive, which is located in it, in order to ensure a continuous uniform distribution of the material during batch feeding of the material, it supplied with measuring capacity under the loading nozzle, and additional screws placed in the body outside the measuring capacity, while the main screw is made of two mating parts, one of which has relative to the lower stationary, the clamp-35 is smaller in diameter p and is located in the tank merged with the body 1. screws are parallel, and are located in The bandage feeder works in the same plane with the main screw., Blowing. 2. ,. Feeder according to claim, 1, o. Tl and When batch feeding the material. 40. due to the fact that the meter is at regular intervals, the time is made with the adjustable series falling into the loading patru. cpuz.Z (pi / gh
