SU939338A1 - Hopper closure for charging receptacles - Google Patents

Description

The invention relates to lifting equipment, namely, devices for transferring bulk materials from a stationary bunker to transport containers.

A known bunker valve for loading containers, containing a shut-off cone, mounted for moving a chute with a drive including a power cylinder, a sleeve for connecting the hopper to the container, and sealing elements 1.

However, the known device is unreliable in operation, since when loading containers from a stationary bunker, dust and gases are inevitably released into the surrounding space.

The purpose of the invention is to increase the reliability of the shutter operation in the conditions of loading containers from a stationary bunker.

The goal is achieved by the fact that in a bunker gate for loading containers containing a locking cone mounted to move a chute with a drive, a sleeve to connect the bunker to the tank and sealing elements, the sleeve is fitted with a flange fixed at its bottom end and mounted concentrically to the chute to be vertical displacement, and the chute is connected to the cylinder by means of pivotally fortified vertical tg connected to the levers.

The bunker closure is provided with spring-loaded rods fixed on the outer surface of the chute, and eyelets are provided at the upper end of the liner to interact with the rods.

The diameter and thickness of the flange of the liner correspond to the diameter and thickness of the liner loaded 4kosti.

Figure 1 shows the bunker shutter (closed) with summed container, closed lid; Fig.2 bunker Zata (closed) connected to the container; in FIG. 3 - bun20 curtain valve (open); in FIG. 4, view A in FIG.

Claims (3)

The bunker stopper consists of a receiving funnel 1 fixed to the bunker with a discharge pipe 2 and a locking cone 3 mounted on a cross 4 in a movable chute 5, the latter being connected with the actuator 6 in the form of vertical joints 7 connected to it with levers 8 fixed on the drive shaft 9. The mobile chute 5 is provided with nozzles: the top 10 (mounted on the discharge pipe 2) and the lower I. The lower sleeve 11 has a protective sleeve 12 attached to the chute with the possibility of vertical movement and provided with a flange 13, the outer edges and thickness of which are made proportionate to the lid 14 of the loaded container 15, equipped with eccentric pressure locks, including hinged bolts 16 and handles 17. To ensure the vertical movement of the protective sleeve 12 to the movable leakage 5 rod supports 18 with springs 19, interacting with lugs 20, cannonically mounted on the protective sleeve 12 Between the pipes 2 and 11, the pipe 10 and the protective sleeve 12, sealing rings 21 and 22 are installed. p works as follows. Bulk material from the bunker-pico comes into the receiving funnel 1 and is held there by a locking cone 3 adjacent to the discharge nozzle 2. A container 15 is brought under the arrestor. Handles 17 turn upwards, the bolts 16 open and remove the cover 14 Next, the heads of the nak bolts 16 are pressed onto the flange 13 and by turning the handle 17 downward they press it against the neck of the container (container) 15, thereby securing the protective sleeve 12 on the container. The actuator 6 is turned on, which rotates the drive shaft 9 and the lowering levers 8, thereby the pull rod 7, and together with them the moving chute 5 with the locking cone 3 and the rod supports 18, leaving a protective sleeve 12 on the throat of the loadable container 15. the receiving funnel 1 and the pipe 2, along the moving estrus 5 flows into the container 15. The shutter is closed in the reverse order. The protective sleeve 12, after releasing its flange 13, is lifted to its original position due to the force of the springs 19, which are after the lifting of the moving chute in a compressed state. Sealing rings 21 and 22 ensure the tightness of the overloading tract, and the communication of the moving chute 5 with the drive 6 by means of the vertically installed t g 7 provides a free, without distortions, movement of the moving chute 5. The technical and economic effect due to the advantages of the proposed device reliability of the device during the transfer of harmful and dusty materials from the stationary bunker into the transport capacity and the improvement of the working conditions of the personnel, as well as and the environment from contamination of harmful dust. Claim 1. Bunker closure for loading containers containing a shut-off cone mounted for movement with a drive with a drive, a sleeve for connecting the hopper with a container and sealing elements, so as to improve the reliability of the gate in conditions loading containers from a stationary bunker, the sleeve is fitted with a flange fixed at its lower end and mounted concentrically with a chute with the possibility of vertical movement, and the chute is connected with a drive by means of hinged fortifications ikalnyh tg connected with levers., 2. The closure according to claim 1, characterized in that it is provided with fastenings on the outer surface. The chutes are spring-loaded rods, and at the upper end of the sleeve there are eyelets for interacting with the rods. 3. The closure according to claim 1, distinguished from I in that the diameter and thickness of the sleeve flange correspond to the diameter and thickness of the lid of the container being loaded.
