Description

(54) DEVICE FOR DOWNLOADING BULK MATERIAL

IN CAPACITY

one

The invention relates to devices for loading bulk materials into a container, preferably in a fluidized bed cooler, and may find application in such industrial fields as metallurgical, chemical, food, etc.

A device for loading bulk material into a container is known, which comprises a housing with a discharge window in its lower part and a rotary valve arranged in the housing and provided with an anti-. weighing 1.

A disadvantage of the known device is that when loading bulk material it is impossible to exclude large inclusions that clog the gas distribution grid of the refrigerator. This 5 leads to a discontinuity in the process and reduces productivity.

The purpose of the invention is to improve the performance of the device by eliminating 20 large inclusions in the material.

This goal is achieved by the fact that

side discharge window, overlapped with a visor rigidly mounted on the valve, made in the form of a lattice.

The device is provided with ejector for large inclusions located inside the case, rigidly mounted on the wall opposite to the side window and entering between the lattice elements when it is rotated.

FIG. I schematically shows a device for loading bulk material into the container in the initial position, general view; in fig. 2 - the same, when driving the grill with large inclusions.

The device includes a housing 1 with an unloading window 2, made in its lower part, a butterfly valve 3 in the form of a grille placed in the housing 1 on the horizontal axis 4 and equipped with a counterweight 5 interacting with the ма-magnet 6 attached to the housing 1 from the outside by means of brackets 7. In the wall of the housing 1 there is a lateral relief opening 8, overlapped with a visor 9 with stiffening ribs rigidly fixed on the flap 3. Inside the housing 1 there are ejectors 10 for large connections rigidly fixed at an acute angle n the wall 11 opposite to the side window and entering between the grid elements during its rotation. The device works as follows. The calcined bulk material from the kiln enters the body 1 and, the passage through the grid 3, enters the refrigerator, and large inclusions (e.g., specs formed in the calcining process, bricks from the furnace lining, etc.) are retained on the grid. When large inclusions are clogged or delayed, the force of gravity exceeds the force of gravity of the counterweight and the force of attraction of the magnets, the lattice rotates on the axis 4 and takes the position (Fig. 2). Simultaneously with the rotation of the shutter 3, the visor 9 is lowered, opening the side discharge window 8, through which large inclusions are poured from the shutter 3 into the container, and the large inclusions stuck in the shutter 3 are ejected by the pushers 10 entering between the grille elements when it is rotated. After the lattice is freed from large inclusions, its gravity becomes less than the gravity of the counterweight and the attractive force of the magnet, and the lattice returns to its initial horizontal position (Fig. 1).

The proposed implementation of the unloading device will allow to mechanize the process of cleaning the lattice from large inclusions, to provide ease of maintenance of the device, to increase the operational data by entering between the lattice elements when it is turned.
