Description

The invention relates to devices for mixing fibrous material consisting of a system of conveyors and feeders, and its aim is to obtain such a design that would not be cumbersome, mechanize the entire mixing process and have high productivity. In order to solve the problem in the proposed device, a number of feeders and conveyors deliver the components of the mixture to a conveyor made of separate trays pivotally connected and installed above the storage sheds. There are two such conveyors, and they alternately feed the fiber into one or another storage shed, from where the mixture is discharged with a needle web, which is mixed across and along the storage sheds.

In FIG. 1 shows a longitudinal section of the device, FIG. 1a is a cross-section, FIG. 6 is a top view, FIG. 2 and 3 - details of the device.

The raw material prepared for blending is loaded into feeders (such as spike feeders), the amount of which depends on the capacity of the blending machine. All feeders feed the fiber to a continuous dvigush, ice conveyor / (fig. B}.

The latter has a direction perpendicular to the direction of the conveyors 5 and 5, and is located so that it passes inside them. Conveyors 5 to 6 are located respectively on labazes 7 and 5 and operate alternately. Their. nesush ;; the surface is a continuous fabric, Ksk at conventional conveyors, and C (standing from trays 4 (Figs. 1 and 2), having a width slightly smaller than the width of the sheds. The fibrous material coming from the feeders to the conveyor belt / is last fed to a working conveyor 5. The direction of movement of both conveyors is indicated in Fig. 1 by arrows. From the conveyor / special ejector in the form of a brush 2, the fibrous material is periodically dropped onto trays 4 of the conveyor 5, which are in a horizontal position and form Brush 2 has the same width as trays 4. At an appropriate conveyor speed of 5 and 5 and the speed of the brush, the fibrous material will be placed on the trays 4 of the conveyor in the form of an equal-layer layer. Since the conveyor 5 is all the time movement, the trays 4 loaded with the fibrous material all the time are moving along the warehouse 7. When the trays above the storage platform are loaded, they all simultaneously lower and assume a vertical position, as a result of which the fibrous material provalivaets in a storage shed. In this way, a labaza is filled in which the entire blender is housed. To compact the fibrous material, a roller / 5 is used, walking along the warehouse and crushing the fibrous material when it is compared with the edges of the walls of the warehouse. Since the filling of the warehouse is made by thin layers of fibrous material, the feeders can be loaded with various types of raw materials arbitrarily, which requires only a certain amount of each component to be supplied during the loading of the warehouse. To achieve a greater degree of mixing, it is possible, when feeding with three or four power supplies, to feed each group of components.

At that time, as the stock 7 is filled, it is unloaded from the stand 8. The discharge is performed by means of a needle-shaped endless grid 9 (Fig. 1 and 3), which has movement around the guide rollers, and during this movement the fibrous material is placed on the needles of the grid. In order to prevent the needles of the lattice from blocking immediately on the lower layer of the fibrous material, on the I1lah are placed the regulating grabs of the fiber planochka 16 (Fig. 3). As the needles of the lattice move from the lower bed to the top, these planks descend from the top of the needles to the base, whereby the fiber is placed on the needles of the lattice during the entire time the lattice moves. In addition, the same plates further along with the brush 10 reduce the fibrous material from the lattice needles, which falls on the side discharge conveyor 12. The conveyor 12, the brush 10 and the grill 9, which are one system,

they also have a forward movement along the warehouse as the fibrous material is unloaded from it. As a result, there is a gradual selection at once of all layers of the bed in the form of small shreds of fibrous material and its complete mixing. From the side conveyor 12, the fibrous material is transferred to the IS conveyor. From the latter, during primary displacement through a pair of conveyors 14, the fibrous material enters again onto the conveyor /, which brings it to the tray conveyor located above the adjacent empty storage shed. After re-mixing, the fibrous material is conveyed by the conveyor 13 moving in the direction indicated in FIG. 1, the arrow is retracted for transfer to distribution stores.

The ready mix is obtained after the friendly mixing. When loading one labaza with a new mix, the finished mix is unloaded from another labaza. Then there is a transfer of the mixture from one labaz to another. Thus the system works all the time. The grating grating 9 together with the conveyor 12 serves both labaza in turn. To transfer the lattice from one storehouse to another, special rounding of rails is arranged, along which the lattice moves. Tray conveyors are installed one at a time for each warehouse.

The subject matter of the invention.
