Description

The invention relates to equipment for the storage and unloading of bulk material and can be used in such areas of the national economy as the construction, chemical and food industries.

A device for discharging bulk material from a container is known, which comprises a cylindrical housing with an outlet opening in the form of a square in a horizontal bottom, under which a damper is mounted with the possibility of reciprocating movements.

However, in the known device for discharging bulk material from a container, the body has a cylindrical shape, and the horizontal bottom is provided with a square hole of small dimensions located along the vertical axis of the cylindrical body and the bulk material inside the body (sand, cement, etc.) will never be unloaded unloaded completely. Most of it, located on a horizontal bottom, at an angle of repose, will always remain in the housing, where it will solidify over time, solidified, and its dimensions will constantly grow, interfering with the operation of the entire device. Manual unloading, as a rule, is impossible, since the upper opening of the hull is closed either with loading devices (chute, funnel, conveyor belt, etc.), or with a lid.

In addition, the horizontal flap under the bottom must move in the side slots of the body, which is impossible in principle, since the gaps of these slots, and they must be, otherwise the flap cannot be inserted into these gaps, will be filled with abrasive material (sand, cement and others), excluding the possibility of moving the valve.

forces exceeding the jamming force of the valve in the grooves will be applied, then if there is a forced abrasive lubricant and the valve, the elements of the grooves will be very quickly worn out and disfigured.

The purpose of the invention is to increase the reliability of the device.

This goal is achieved by the fact that the device for unloading bulk material from the tank, containing a cylindrical body and mounted with the possibility of reciprocating movement of the valve with a V-shaped notch on the end, is provided with a conical element rigidly attached to the bottom of the body, having a circular shape equal to the diameter of the body, and the bottom - having a square shape, the sides of which are at an angle of 45 ° to the direction of movement of the flap, which is made of a U-shaped cross section with two rollers on each side, valuable guides mounted in the spring, pressing the damper to the lower edges of the conical element with adjustable force, while the damper on the rollers on the spring-loaded guides moves from the platform mounted on the platform rigidly attached to the housing.

FIG. 1 shows a device, side view; in fig. 2 - the same, end view; FIG. 3 is the same, top view.

The device for unloading bulk material comprises a cylindrical body 1, provided with a conical element 2 attached to its lower part, having, in the place of attachment to the body, in the upper part, a cross-section in the shape of a circle, and in the lower part - in the form of a square, pad 3, rigidly attached to the housing in place of the conical element 2 and provided with four bushings 4, which are guides for threaded rods, rigidly attached to the guides b, rollers 7 for interacting with the guides 6, the flap 8 installed with the possibility of reciprocating movement in the guides by means of rollers, while the valve is made in the form of a 9-profile U-shaped with an end wall 9, on the shelves of which rollers are installed. The valve travel actuator is mounted on the platform 3 of the housing and has a screw 10 rigidly fastened to the wall 9 on which a nut 11 is screwed, the outer surface of which is made in the form of an asterisk, connected by a chain 12 with the star 13 of the engine 14. The guides 6 are mounted spring-loaded relative to the platform 3 enclosures by springs

15 mounted on threaded rods 5 and nuts that are tightened to a predetermined force

16, which adjust the spring stiffness.

Square hole 17 conical

element 2 is located so that the sides of the square are at an angle of 45 ° to the direction of movement of the valve 8, which has a V-shaped notch 18 at the end.

The device works as follows.

The motor 14 is turned on to close the square opening 17 of the conical element 2, as a result of which the rotating sprocket 13 of the engine 14, by means of the chain 12, signals the rotation of the nut 11, while rotating which the screw 10 moves to the right, moving in the same direction

the damper 8 on the rollers 7 along the guides b until the square hole 17 is completely closed. Since the guides 6 by the springs 15, tightened with a predetermined force, tend to move up; then they move the flap 8 upward and press it to the lower edges of the conical element 2 with a predetermined force, excluding the gaps between them and the penetration of the bulk material. In case 1 load loose

material.

When unloading bulk material, the motor 14 is turned on to open the square hole 17 of the conical element 2. As a result, the flap 8 moves

To the left, open the square hole 17 to the desired size.

Since the conical element 2 does not have a bottom, when the square hole 17 is fully opened, all bulk material is discharged from the housing 1, which positively affects the performance of the shutter.

Since the springs 15 press the flap 8 against the lower edges of the conical element:

2 with a given force without gaps, this eliminates the penetration between the rubbing elements of the abrasive material, which increases the reliability of the device. The U-shaped profile of the valve with rollers on the shelves of this profile Provides the strength characteristics of the valve required for a reliable connection of the valve with the outlet.

The arrangement of the sides of the square section of the conical element at an angle of 45 ° to the direction of movement of the flap ensures reliable operation of the device when unloading material in a container with inlet openings of various sizes and shapes.
