Description

The device for loading and unloading high-pressure chambers with various materials, including granular with liquid, can be used in metallurgy, chemical industry, enrichment, etc.

It is known "Loading and batching device of vacuum installations" (SU No. 558157, IPC G01F 11/00, published 05/15/1977), containing an airlock with electric drive, a complex system of inlet and outlet valves and a removable feed hopper.

Common signs of the claimed device with an analogue are the presence of a removable consumable hopper (container) and a sealing system.

The disadvantages of this device are the complexity of the design and sealing system with slip pairs.

Known open airlock loading device for vacuum installations (Frolov V.S. Vacuum technology. Handbook. - M .: Mashinostroenie, 1992, p. 198), including a rotary cell mechanism for the continuous supply of bulk materials into an evacuated working cavity, an air pumping system and a system seals for dosing and transporting mechanisms.

Common signs of the claimed device with an analogue are the presence of chambers for transporting materials and a sealing system (seals).

The disadvantages of this device are the following: limited dose performance, frequent damage to the sealing of the metering and conveying mechanisms due to constant friction and the ingress of solid particles, difficulty in manufacturing, large air leaks that require an increase in pumping capacity, and the vacuum system is not exposed to dust particles .

It is known "Device for container locking of various substances into high pressure zones (options)" RU No. 2206382, IPC B01J 3/03, B01J 3/2, published on 06/20/2003.

The device includes a receiving chamber with a platform - a container for the transported substance, a transition chamber, an intermediate transition zone housing, sealing elements and a gas supply system to the transition chamber and its release from it, equipped with telescopic power drives of the lower and upper areas of the lock, a lower movable cup associated with the power drive of the lower zone of the lock, the drive of the capture rod of the transition chamber, the pushers returning the container from the zone of the receiving chamber, while the power drives of the lower and upper zones the user interface, as well as the housing of the intermediate zone and the external housing of the high-pressure zone are located on a common vertical axis, and the transition chamber is movable and connected to the power drive of the upper zone of the lock. The device has a system of hydrodynamic and / or magnetohydrodynamic sealing, made in the form of a cylindrical insert, equipped with an upper annular collector, channels of the labyrinth sealing zone and a lower collection manifold, which collects leakage of sealing liquid for its return to the upper annular collector with the creation of recirculation.

Common signs of the claimed device with an analogue are the presence of a container for transporting a variety of substances and a sealing system.

The disadvantages of the device are insufficient reliability due to the complexity of the device as a whole and the sealing system in particular. The ingress of solid particles on the sliding friction and sealing surfaces leads to their wear and deterioration of the sealing conditions.

As a prototype taken "Device loading and unloading of high-pressure chambers" RU No. 135939, IPC B01J 3/2, published 12/27/2013. The device includes a container for the transported substance installed in the opening of the working chamber body in an elastic conical torus filled with liquid or gas under pressure and equipped with a feeder for regulating the pressure in the torus cavity.

The disadvantages of the device is the non-technological conical shape of the torus design, which determines the nonlinearity of the power and speed characteristics of the drive.

The task of the invention is to create a simple, reliable and technologically advanced drive with linear power and speed characteristics for loading and unloading material from the high-pressure zone of the apparatus.

The technical result of the claimed invention is to increase operational characteristics by simplifying the design of the torus.

The technical result is achieved by the fact that in the inventive device for loading and unloading high pressure chambers with various materials, including granular, the peripheral surface of the elastic torus is made in the form of two cylindrical steps, and the torus is installed in the opening of the working chamber body with a step of a larger diameter from the side of the high chamber pressure.

The execution of the peripheral surface of the torus in the form of two cylindrical steps with the installation of a larger diameter step on the side of the high-pressure chamber provides a linear dependence of the actuator working force on the pressure inside the torus, a linear dependence of the speed of movement on the amount of liquid or gas supplied to the torus, which simplifies and facilitates the control of the torus drive. In addition, the cylindrical torus is more technologically advanced in the manufacture and operation.

The installation of a torus in the opening of the working chamber body with a cylindrical section of a larger diameter in the direction of the high-pressure chamber makes it possible to ensure reverse movement of the container with a decrease in pressure in the torus cavity due to the pressure inside the working chamber of the apparatus.

The difference from the prototype is the implementation of the elastic torus, the peripheral surface of the elastic torus is made in the form of two cylindrical steps, and the torus is installed in the opening of the working chamber body with a step of a larger diameter from the side of the high pressure chamber.

The presence of distinctive features allows us to conclude that the claimed devices, the criterion of "novelty."

The proposed device for loading and unloading high pressure chambers is illustrated by drawings, where in FIG. 1 shows a general diagram of a device for loading and unloading high pressure chambers in the loading position of the dispenser chamber, FIG. 2 is a diagram of a device for loading and unloading high pressure chambers in the unloading position of the dispenser chamber, FIG. 3 shows a cross section of a dispenser chamber.

The device consists of a loading hopper 1, a working chamber 2, a container 3, in which a granular medium moves 4. The dispenser container 3 is a conditional cylindrical container formed by cylindrical guides 5 and 6, and the side faces of plates 7 intersecting along the longitudinal axis of the container 7. The container 3 is mounted and held in a conical torus 8 located in the conical opening of the housing 9. The reciprocating movement of the container 3 is carried out by inverting the inner surface of the conical elastic torus when the pressure in its cavity is changed using the feeder 10. The upper and lower position of the torus are determined by the stroke limiters of the dispenser 11 and 12 (Fig. 1, 2), while the gap in the hole between the limiter 11 and the surface of the upper guide 5 is smaller than the grain size of the medium . The upper end surface of the guide 6 to improve the discharge is made in the form of a cone.

The device operates as follows. In the upper position, the guide 5 rises above the limiter 11, opening the cavity of the container 3 to fill it with grains of the working medium. The pressure in the torus cavity is set to a value that satisfies the conditions for ensuring the sealing of the high pressure zone. After filling the container 3, with increasing pressure in the conical elastic torus 8, it begins to twist (envelop) in the axial direction and moves to the lower position, lowering the container. In the lower position, the guide 6 extends beyond the torus 8, connecting the space of the working chamber and the container. The granular medium 4 pours out under the action of its weight into the working zone of the chamber 2. After unloading, when the pressure in the cavity of the torus 8 decreases, under the pressure in the working chamber, it moves in the opposite direction, moving the container 3 to its original position and the loading cycle of the working chamber is repeated.

Thus, the proposed device provides increased reliability by simplifying the design.
