Abstract

The invention relates to chemical engineering, in particular, to devices for storing and metered discharge of dry chemical mixtures prone to arborization. The purpose of the invention is to reduce energy consumption and increase the reliability of the crumbling of bulk materials from the tank by self-regulating the operation of the unloading auger. The blades 10 of the drive sleeve move the material from the tank 1 to the discharge window 3. The drive sleeve axially moves along the shaft 6 in the direction opposite to the material feed direction, disengages the cam coupling halves and stops the interaction of the drive sleeve with the sleeve 8. When a set of bulk material is formed in the tank 1, axial the force in the drive sleeve disappears, it is shifted by the spring 14 to its original position, and the cam half couplings re-close and begin to transmit rotation to the intermediate sleeves 8 of the shaft 6. In the event of formation of the arch material along the entire length of the unloading auger springs hold all the coupling half in a closed position. At the same time, the rotation of the sleeves is transmitted to the shaft 6, and from there to the gear roller 20, which, by moving the fixed gear 18, moves the unloading screw 4 inside the tank 1 parallel to the bottom of the forming 2 to the zone of contact with the array of material. 1 hp ff, 6 ill.

the sleeve disappears, it shifts with a spring to its original position, and the cam coupling halves re-close and begin to transmit rotation to the intermediate sleeves 8 of the shaft 61. In the case of formation of the arch of the screw along the length of the spring unloading screw, they keep all the coupling halves in a closed position. By this, the rotation of the sleeves is transmitted to the shaft 6, and from there to the toothed roller 20, which, by moving the fixed gear 18, moves the unloading screw 4 inside the tank 1 parallel to the bottom forming 2 to the zone of its contact with the array of material. 1 hp f-ly, 6 ill.

Discharge Auger Works

Figure 1 shows the pit-bunker. The telegraph, a general view in FIG. 2, is a section A-A in FIG. 1-, in FIG. 3, a unit for engaging drive elements with a discharge screw; FIG. 4 shows the mutual position of the sleeves and the cam auger clutches when unloading the material in the absence of the roof in the tank; fig.Z - the same, with the formation of the arch in the tank; figure 6 - the same, when unloading the remnants of the material from the tank.

The feed hopper for the extruded materials contains a tank 1 with a conical bottom 2 and a discharge window 3, filled in its central part, mounted along the generatrix 3 of the discharge unloading paddle screw 4 40 and the drive 5, which includes a node with an auger 4. The latter is made composite and includes movably mounted on the shaft 6 bushings: leading 7, “intermediate-45 wires and end 9, with the blades 10 rigidly fixed to the bushings.

The free end 11 of the screw 6 of the screw 4 has a protrusion 12, while the sleeves 7, 8, 9 and the protrusion 12 are provided with 50 cam half-couplings 13 and are mutually spring-loaded by means of steel springs 14 with the possibility of coupling and disengaging of the 13 thermometers.

The clutch assembly contains: the drives 5 mounted on the shafts 15 and 16 of the drive gear 17 and the fixed gear 18 are spotted, rigidly wired

Replaced 4 gear teeth 20 on the lower end 19 of the screw shaft 6, connected to a fixed gear 18 to move the screw 4 in parallel forming the bottom 2, and mounted on the drive bush 7 with a gear in the slots 21 along its axis; connected with a running gear 17 for transmitting rotation on the blade 10 of the screw 4.

In order to prevent the particles of the impacting material from falling into the internal cavities and gaps of the discharge screw 4 between the sleeves 7 and 8, 8 and 9, as well as between the adjacent sleeves 8, flexible sealing elements 23 can be installed.

The hopper feeder works as follows.

The actuator 5 provides rotation of the drive sleeve 7, the blades 10 of which move the bulk material from the tank 1 into the discharge window 3. The axial force arising due to material friction shifts the drive sleeve 7 along the shaft 6 in the direction opposite to the material feed direction, squeezing the spring 14 and opening when In this case, the corresponding cam coupling halves 13, thus terminating the interaction of the sleeve 7 with the adjacent intermediate sleeve 8. At this moment, the material is fed into the discharge window 3 only by rotating one drive shaft. 7. tulkus 1

In the formation of a set of bulk

The material in the tank 1 axial force in the drive sleeve 7 disappears and it is shifted by the spring 14 to its original, position. The cam coupling halves 13 are again closed and begin to transmit rotation from the actuator 5 to the intermediate bushings 8 of the shaft 6. Located below the material arch in the container 1 of the bush 8 during rotation

Axial forces are being tried, since the material does not move to the discharge window 3, the coupling halves 13 remain closed. The sleeves 8 located in the bulk material (above the formed wedge), receiving rotation from the drive 5 and under the arch of the sleeve 8 begin to move the bulk material, thus destroying the formed arch.

If a material arch is formed along the entire length of the unloading screw 4 or when unloading residual material from the tank 1, the axial force keeps the springs 14 of all coupling halves 13 in the closed position, during rotation of the sleeves is transferred to the shaft and the gear roller 20 starts to run around the stationary gear wheel. 18, which causes the unloading auger 4 to move inside the tank 1. When the unloading auger 4 contacts the bulk bulk material in the tank 1, the drive bush 7 blades 10 again begins to move the material, compresses the corresponding spring 14 and opens the coupling halves 13 — the rotation is in the material of the adjacent sleeves ceases.

In this way, the waste of energy on the friction of the material being moved against the inner layers of the array is prevented. Constant contacting of the gear wheel 22 with the drive 5 while moving one or several bushings on the shaft 6 is both baked by moving it in the splines 21.

Making the screw self-regulating can significantly reduce the energy consumption of the process of unloading bulk materials, increase the capacity of cylindrical storage facilities (silos) and completely refuse
