Abstract

Use: for the production of loose rock mass and viscous clay materials from containers, such as bunkers, in the mining, construction, chemical and other industries. SUMMARY OF THE INVENTION: A vibratory conveying device comprises a curvilinear resilient working member associated with a frame, a single-acting vibration exciter with outlet channels, tanks with holes and a flange, and an exciter made hydraulic, while the containers are installed under the loading part of the elastic working body and on board and connected to the exhaust channels of the vibration exciter through pipelines. At the extreme upper position of the piston of the hydraulic vibration exciter, the exhaust channels open, and the fluid from the vibration exciter chamber flows through the pipelines into the tanks and through the holes with canopies that set the jet in the right direction, wets the beads and the tool. When the clay material is discharged, the fluid entering the working body and the sides of the device drastically reduces the viscous resistance forces and, under the action of vibration excited by a hydraulic vibration exciter in the working body, the material moves. When a loose rock mass is released, the viscous resistance is negligible, and the flow of fluid into the near-wall layer does not have a noticeable effect on the movement of the material. 1 hp ff, 1 ill.

Description

vj SL

The invention relates to devices for discharging loose rock mass, as well as viscous clay materials from containers such as bins, and can be used in the mining, construction, chemical and other industries.

A known method of vibrating the transportation of bulk materials using water to irrigate the load-carrying surface of the conveyor in order to prevent the material from sticking.

In a single transport system, a device is known for transporting into optic plastic materials comprising a trunk pipeline with an annular gap, a container and a port for introducing a less viscous liquid into the near-wall layer. However, without significant structural changes, the installation cannot be used to release viscous materials from containers, such as bunkers, to vehicles.

O u

However, the presence in the pipeline transport of devices for the supply of fluid and its subsequent collection complicates the design and reduces its reliability.

Closest to the present invention is a vibration device that includes a curvilinear elastic working body associated with the base, and a pneumatic vibration exciter mounted on the base. Such a device can be used for transporting broken rock mass through inclined openings, for discharging bulk material from tanks (ore chutes, bunkers), etc.

However, during transportation of viscous clay materials, because of the significant amount of viscous friction force, the material movement speed drastically decreases, and the material stays on the vibrating body increases. When this occurs, the compaction of the material, sticking it to the working body and ultimately - the cessation of release.

The aim of the invention is to provide transportation of bulk and viscous clay materials by eliminating sticking of the material to the working member.

The goal is achieved by the fact that a device having a curvilinear elastic working body connected to the frame and a single-acting vibration exciter with exhaust channels is equipped with capacities with holes and a flange, and the vibration exciter is made hydraulic, while the tanks are installed under the loading part elastic working body and on board and connected to the outlet channels of the vibration exciter through the pipeline.

In addition, there are visors above the openings of the containers.

The drawing shows the scheme of the proposed vibration device.

The vibrating conveyor device comprises a working member 1 attached to the frame 2, and a hydraulic vibration exciter consisting of the housing 3 and the piston 4. The housing 3 and the piston 4 form the working chamber 5 connected to the main duct 6. The housing 3 of the vibration exciter with the lower part attached to the frame 2, and in the upper part has exhaust channels 7 connected by pipeline 8 with containers 9 attached to the working body 1 in its loading part and on board 10 of the device. Capacity 9 have holes 11, over which are placed the visors 12.

The device works as follows

In the initial state, the piston 4 is under the constant influence of the elastic force of the pre-stressed working body 1 and with some effort

pressed against the supporting part of the housing 3 in the lowest position, blocking the exhaust channels 7.

The fluid through the pipe 6 enters the working chamber 5, acts on the piston

4, which, under pressure, moves upward and affects the working body, bending it. When the piston 4 moves upward such that the outlets 7 are open, fluid from

chambers 5 through pipelines 8 enters the tank 9 and through the holes 11 with visors 12 defining the liquid jet in the right direction, wets the beads 10 and the working member 1. The fluid pressure in the chamber 5 drops, under the action of elastic forces of the preloaded working body 1 piston is lowered, blocking the outlet channels 7. The pressure in chamber 5 begins to rise, the piston starts moving up again and the cycle repeats. When a viscous clay material is released, the liquid entering the working body and the beads of the vibrating device dramatically reduces the forces of viscous resistance and under the influence of

vibrations, excited by a hydraulic vibration exciter in the working body, the movement of a viscous clay material. With the release of loose rock mass flow of fluid in the near-wall layer

It does not have a noticeable effect on the movement of the material, although the presence of a liquid reduces dust emission during transportation.

Laboratory tests of an experimental sample of the device showed that the release of clay material from the bunker with a moisture content of 30-40% only with the help of 15 Hz vibration was very slow and completely stopped 3040 seconds after switching on the vibration exciter, while the material adhered to the working organ with a thick layer.

With the same modes of vibration exciter, but with the supply of liquid to the near-wall layer

(proposed device) within 25-30 seconds without any sticking to the working body, all the material in the bunker was produced.

The effectiveness of the proposed vibration device consists in expanding the functional capabilities, with the real possibility of discharging both bulk and viscous clay material from the tank.
