Description

one

The invention relates to the technique of high-performance material from rasnite, 1; 1yy sushi.tok and can be used in the industry of building materials.

A device for unloading sonar materials is known, which includes a chute with front and rear walls and is pivotally mounted under its lower edges with the possibility of vertical movement of a feeder with a counter load 1.

The disadvantage of this device is the unloading of material in one cycle due to the application of force to the traction lever and the formation of large gaps, which contributes to the penetration of air into the chute.

The closest to the invention but the technical essence and the achieved result is the device for unloading ci) material materials, including a point with an occasional and rear wall and H1 harnessed under its lower edges with the possibility of vertical movement of the tape thread with adjustable counterweight 2.

In this device, the task of unloading bulk materials with a constant average productivity is solved, and due to the lower edge of the front wall of the leak in the plane at an angle to the plane passing through the edges of the other walls of the feeder and the location of the feeder in the middle of the leak does not ensure the contact of the tape nitratel with all lower edges of the chute and its sealing.

The aim of the invention is to improve the sealing of the chute by balancing the layer of material in the chute with an adjustable counter-load.

This goal is achieved by the fact that in the bulk material unloading device, which includes a chute with front and rear walls and a hinged node with its lower edges with the possibility of vertical movement of an adjustable thread, the hinge of fastening the belt feeder is mounted on the rear wall of the chute, and the lower edges of the string arranged in the same plane with the possibility of interacting with the other tape feeder at its upper position.

In addition, the device has a limiter placed under the belt feeder (we are an emphasis.

The drawing schematically depicts the device.

The device includes chute 1, mounted 1) 1Y under it a belt feeder, containing frame 2 and tape 3. Tape frame frame with (single with back wall 4 chute 1 111-1-n (by means of HiapHHpa 5. On the front wall; Ch1chi 1 there is a block 7, through which. .I jxriieH is a cable 8. The last one with its IM iip.HKi.eii.; (To version 2, and on the second

The end of the cable 8 is fixed, adjustable. Counter1-ruz 9. The weight of the load 9 is selected from the condition of equilibration of the feeder and the weight of the sealer, its layer of material from the chute.

The thickness of the 1m.metal layer of material located in K is selected on the basis that this material is sufficient to completely10 fill the gap between the edge of the thread and the ribbon of the feeder at the maximum deviation of the gauge in the vertical direction.

By the action of load 7, the feeder tends to occupy the upper position, in which the tape 3 of the feeder fits snugly against the lower edges 10 of the chute 1 located in one plane, and the material is almost not ejected from the chute.

Node frame 2 is installed stop 11 associated with estrus 1, limiting the movement of the frame 2 value, corresponding to the first MaKCHivia.Tbiio permissible then.pc syu.materiala tape 3 at max.chuyu P1) () from the sensitivity of the supershlki.

The device works as follows.

In the conical part of the spray dryer, the dried material CC1) is fed into the chute 1. At the start of the hook switch B of the drain 1, at the initial moment of time, there is a sealing c.: 1C) of the material. Under the action of the load 9, the tape feeder is firmly pressed by the tape 3 to the lower edges 10 of the heat 1, sealing the spray dryer. Moreover, the material from the chute 1 is not discharged.

The height of the material is gradually inflated in the heat of I, and its weight exceeds the weight of the sealing of the bed. The system is out of balance, and the frame 2 is rotated on the hinge 5. Between the tape 3 and the edges 10 of the chute 1, a gap is formed, which is filled with material, and the dried material is fed by the tape 3 to the next technological processing, for example, pressing kirnich.a. The maximum thickness of the layer of material found on the belt 3, with the maximum capacity of the suction head, is determined by the position of the stop 11, which limits the vertical movement of the feeder, thereby limiting the size of the gap between the leading edge 10 of estrus 1 and the molded 3.

Due to the constant presence of a sealing layer of the material in the chute 1, the gap between the edges 10 of the chute 1 and the belt 3 during the unloading process is completely filled with material, which prevents the possibility of cooling air leaking into the spray bottle, i.e. ensures its compaction in the process of unloading material.

As the powder from the chute 1 is consumed, the weight of the threshold is reduced, giving pgego to the belt 3 of the feeder. She reaches 1

values equal to or less than the minimum value, in which the weight of the feeder and powder is balanced by the load 9, and the frame 2 of the feeder is turned upwards. In this case, the dispensing of the material is stopped, and the feeder belt 3 is pressed against the lower edges of the chute. The remaining powder and the ribbon 3 of the feeder, pressed against the lower edges of the chute 1, compacted the spray dryer.

In case the dryer operates in idle mode for a long time, a contact switch (not shown) can be installed on the chute 1, which switches off

Drive 1b drive feeder in position when mite 3 is pressed against estrus 1.

Thus, this device by creating a sealing layer in estrus 1 and constantly striving to ensure a raft fit of the feeder's mite to the estrus, allows for an easy desaturation of the spray chute during the unloading process, both in the nominal capacity mode and with the production mode. A: 1 is full of nominal. At the same time, cold air inflow into the spray dryer is eliminated, which allows for a reduction in fuel consumption on the sump.
