Description

one

The invention relates to equipment for the opening and emptying of drums with bulk substances, mainly caustic soda, and can be used in electroplating shops in non-ferrous metallurgy and in the chemical industry.

According to the main author. St. No. 554184, a device for opening and emptying drums is known, comprising mechanisms for moving the drums and cutting the bottom and a device for extracting material.

However, in the known device, opening the drum with loose substances by cutting the bottom, spilling of the undissolved substance occurs, which worsens the dissolution process and reduces the productivity when preparing solutions.

When the drum is opened, the granulation does not completely drain the solution due to the lack of fixation of the drums to the positions from turning. In this case, turning occurs depending on the amount of the substance contained in the drum and the change in the position of its center of gravity relative to the drain hole.

Drum fixing is necessary to set the holes punctured in the bottom of the drums to the lower position in the penultimate position to completely drain the solute from the drum before unloading. In order to fix the drums and thereby ensure complete discharge of the substance, the proposed device is equipped with a disk attached to the ends of the plates and with needles located on its periphery to pierce the drums.

FIG. 1 shows schematically the proposed device for opening and emptying the drums, general view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 2; in fig. 4 shows a section along BB in FIG. 2 (turned).

The device contains mounted on

the frame 1 is a mechanism for moving the drums, comprising a housing 2 with axially mounted plates 4 on the shaft 3 with plates 4, to the ends of which a disk 5 with needles located around its circumference is attached; a material removal device consisting of needles 6 and 7 and pressure plate 8; a device 9 for dissolving and removing material with distribution pipes 10 and 11 for supplying the solution,

mounted on the cover 12; an actuator 13, a nozzle 14 for draining the solution, and an ejector 15 for removing the drum 16 from the needles 6.

The device works as follows. The drum 16 with bulk materials is fed between plates 4 to position 17, where

needle 7 pierces its bottom. The disk 8 then presses the drum 16 against the disk 5 and pins on the needles 6, by which it is fixed at all positions of the movement mechanism from turning (rolling) as it moves, with the holes in the bottom of the drum being punctured near its generator. At other positions in the process of moving the drum, the bulk material is removed from it in the form of a solution, while the dissolution is carried out by the liquid supplied through pipelines 10 and 11 to the device 9 for dissolving and removing the material.

Dissolved material is drained from drum 16 through openings 18 and 19 into body 2, and from body through pipe 14 at the bottom of the device into the receiving container (not shown).

At position 20, the ejector 15 removes the drum from the needles 6, and the remaining solution in it is drained through an opening 19 formed by a needle located at the bottom of the drum. To completely drain the solution, the drum is tilted toward this opening

by tilting the lower part of the housing 2, after which the empty drum is removed from the device.

The proposed device for opening and emptying the drums ensures that the drums are fixed at the positions of their movement from the turn and allows the drilled holes in the drum to be oriented with a device for extracting material.
