The aim of the invention is to reduce dust emission. The device for handling bulk materials comprises a housing 1 with a receiving water

Description

one

The invention relates to devices for transferring bulk materials, mainly granular, with simultaneous expansion and can be used in the mining, construction and other sectors of the national economy.

The purpose of the invention is to reduce dusting. .

FIG. 1 shows a device with a shell placed inside it, general view; in fig. 2 is the same at the time of removing the inflatable envelope from the housings in FIG. the same, in the process of handling bulk material.

The device for reloading bulk materials comprises a housing 1, which consists of two sections, having the shape of a truncated cone and connected between themselves by large bases. On the upper section of the housing 1, the receiving gate 2 and the hopper 3 with the hatch 4 are installed, and in the lower section there is an unloading opening 5. Concentric to the upper section of the housing there is an inlet 6 in it. Through the hatch 4 inside the housing you can put a sealing cone 7 made of material that is not stretchable by external influences, such as rubberized fabric

When the cone pipe is filled with air, it takes the form of a truncated cone. In the lower smaller base of it is installed a ring 8 of conical shape, which in size is able to block the outlet. The dimensions of the ring 8 should be smaller than the dimensions of the upper opening of the nozzle 6. The rods 9 are mounted on the forming sealing cone 7, the ends of which are provided with the rings 10. With these rings, the lower ends of the rods are hinged to the crowns 11 of the rings 8, and the upper leads 12. Rods 9 may be sewn between fabric layers. A pipeline 13 is attached to the upper part of the sealing technical nozzle, through which the nozzle 7 is filled with compressed air. Leads 12 are attached to the flexible link 14, with which the nozzle 7 is lowered into the device case or removed

, out of him. The bend 14 is connected to the exhaust valve 15, providing compressed air from the nozzle 7 when it is raised. A flexible element 16 is also attached to the flexible coupling, which, when the socket 7 is placed in the housing, closes the opening in the socket 6. The walls of the lower housing section

made perforated and connected to the system 17 aspiration. The device is mounted on the lid of the storage bin 18.

five

The device works as follows.

The sealing conical pipe 7 through the hatch 4 is placed inside the housing 4pas 1. The ring 8 closes the opening 5, and the stop piece 16 - the hole in the pipe 6. Through the pipe 13 into the pipe 7 compressed air is supplied. After the conical tube is filled with air, an annular cavity remains between the walls of the housing and the nozzle 7, which is filled with loose material coming in after nepcr iiy: Kn n; in with increasing matching of the filter layer due to the settled plate, the aspiration system and the filter layer under the force of gravity, it pours into the storage bunker.

Claims (2)

Invention Formula A device for reloading bulk materials, comprising a casing with loading and lower discharge openings, connected to an aspiration system of dusty air through a perforated section of its walls and made of lower and upper sections having the shape of truncated cones interconnected by large basic funnels 2. At the end of forming-2o, the sealing conical filtering layer includes a nozzle connected by means of an upper aspiration system 17 and bulk material is kept on the perforated wall due to vacuum. Then 25 the air from the pipe 7 is exhausted, it is removed from the body, and the hatch 4 is closed. Next, the material is reloaded through the device, the main part of which moves through the center of the device, and the other between the wall of the upper section of the housing and the nozzle 6. Due to the rarefaction created inside the housing, the dusty air from the hopper 3 and from the storage bin 18 enters the housing and the passage through the moving material and the fixed filter bed is cleaned and ejected into the atm, the mosphere. thirty 35 ends of rods with flexible thrust and installed with the possibility of vertical reciprocating movement, characterized in that, in order to reduce dust release, the sealing conical nozzle is made in the form of a flexible shell communicating with a source of compressed air which the above-mentioned rods are placed, and the device is provided with a diaketrom ring hinged at the lower ends of the rods. equal to the diameter of the unloading opening of the housing, and the locking element stopped on t with the possibility of blocking the loading opening of the housing. After the termination of nepcr iiy: Kn n; in with an increase in the resistance of the filtering layer due to the settled flow, the aspiration system is turned on and the filtering layer under the action of gravity is poured into the storage bunker. Invention Formula A device for reloading bulk materials, comprising a housing with loading and lower discharge openings, connected to the aspiration system of dusty air through a perforated section of its walls and made from the lower and upper sections, having the shape of truncated cones interconnected by large bases, and sealing conical pipe connected by top vanes, and a sealing cone connected through the top ends of rods with flexible thrust and installed with the possibility of vertical reciprocating movement, characterized in that, in order to reduce dust release, the sealing conical nozzle is made in the form of a flexible shell communicating with a source of compressed air which the above-mentioned rods are placed, and the device is provided with a diaketrom ring hinged at the lower ends of the rods. equal to the diameter of the unloading opening of the housing, and the locking element stopped on t with the possibility of blocking the loading opening of the housing.
