Description

Technical Field

[0001] The utility model relates to the technical field of mine dressing equipment, namely a mine filter feeding device. Background Art

[0002] In the past, the main concentrate dehydration equipment in the mining grinding process was the disc filter. Factors that affect the moisture index of the disc filter concentrate include vacuum pump pressure, air pump pressure, water pump pressure, etc. The physical properties of the concentrate itself are also very important, including concentrate concentration and whether it is evenly fed into the filter. The concentrate concentration can be adjusted by feedback data from the concentration meter and the solenoid valve to control the amount of water. Whether the concentrate is evenly fed into the filter requires an appropriate and reasonable feeding device. Take the PKS5 / 2.1-50M currently in use as an example. 2 Taking the disc double vacuum filter as an example, in the past, the slurry was fed into the middle of the filter by pipe connection. Although the filter was equipped with a stirring device, it reflected that the filter fan in the middle of the filter adsorbed a thicker concentrate filter cake, and the concentrate moisture index was higher; the front and rear filter fans adsorbed a thinner concentrate filter cake, and the concentrate moisture index was lower. This shows that when the filter was working, the concentrate was not evenly fed into the front, middle and rear parts, making it relatively difficult to accurately control the concentrate moisture index. Utility Model Content

[0003] The utility model aims to provide a mine filter feeding device with uniform ore feeding and good use effect in view of the above-mentioned shortcomings.

[0005] The above scheme also includes:

[0006] The length of the white steel grate is one third of the length of the buffer zone.

[0007] Lock buckles are welded on both sides of the upper cover along the length direction.

[0013] See also Figure 1 -3. The names of the parts are as follows: ore feeding pipe 1, lock buckle 2, upper cover 3, upper cover opening 4, stainless steel grate 5, buffer zone 6, partition 7, ore unloading area 8, ore unloading pipe 9, trough body 10.

[0014] See also Figure 1-3. The feeding device of the mine filter includes a tank body 10 with an open top, and multiple unloading pipes 9 are spaced and evenly connected at a certain distance from the bottom of the tank body 10 at a vertical height. The unloading pipes 9 are connected to the outside of the tank body 10. A partition 7 is arranged inside the tank body 10 along the length direction. The partition 7 divides the tank body 10 into two areas, an unloading area 8 and a buffer area 6, along the width direction. The height of the partition 7 is lower than the tank body 10, so that the steadily rising liquid level passes over the partition 7 and enters the unloading area 8. A section of white steel grate 5, or slag removal grate, is covered and connected at the middle of the buffer area 6 corresponding to the feeding pipe 1. One end of the white steel grate 5 is connected to the partition 7, and the other end is connected to the rear of the tank body 10. The length of the white steel grate 5 is 1 / 3 of the length of the tank body 10. It should not be too short to ensure sufficient slag removal area, nor too long to form waste. The tank body 10 is provided with an upper cover 3, on which a feeding pipe 1 communicating with the inside of the tank body 10 is connected. Lock buckles 2 are welded on both sides of the upper cover 3 along the length direction. The upper cover 3 of the tank body 10 is made of a 2mm thin plate, with lock buckles 2 welded on the edge, and can be fastened to the tank body 10 with M16 bolts, which is convenient and quick to disassemble. The upper cover 3 of the tank body 10 is opened at the corresponding position of the feeding pipe 1, and the hole diameter is consistent with the diameter of the feeding pipe 1. In principle, the feeding pipe 1 should pass through the cover plate 3. The height of the unloading pipe 9 from the bottom of the tank body should be consistent to ensure that multiple unloading pipes can unload ore synchronously on the same horizontal plane. The lock buckle 2 of the upper cover 3 and the tank body is made by hand, so as to facilitate the disassembly of the upper cover 3. The shape of the lock buckle 2 is not limited to this homemade method, and can be selected and made by yourself. The length of the unloading pipe 9 should be determined according to the actual situation on site, so as to meet the standard of the slurry entering the mixing tank of the filter.

[0015] The feeding device of the mining filter is a trough body 10 with a length of 4500mm, a width of 450mm and a height of 500mm, which is open on the top and is made of 8mmQ235 steel plate; the 8mmQ235 steel plate is cut into two pieces, each of which is 3900mm long and 500mm high, and is 390mm long and 500mm high. The steel plates are welded in parallel at a distance of 30mm from the inner wall of the trough body 10 to form a space and fill it with cement mortar. The bottom of the trough body 10 is filled with 30mm thick cement mortar, so that the inner wall of the trough body 10 is thickened as a whole. Cut two 8mm Q235 steel plates with a length of 3900mm and a height of 270mm, and place them 30mm apart along the length of the tank body to form a space in the middle. They are then welded parallel to the inside of the tank body 200mm away from the rear of the tank body to form a partition 7. The space of the partition 7 is filled with cement mortar to separate the tank body into two areas. The rear of the tank body is the buffer zone 6, and the front is the unloading zone 8. At the corresponding position of the buffer zone feeding pipe 1, one end is on the upper edge of the partition 7, and the other end is at the rear of the tank body 10. A white steel grate 5 with a length of 1500mm and a width of 200mm is welded. In the unloading zone 8, 200mm away from the tank body, a white steel grate 5 with a length of 1500mm and a width of 200mm is welded. The vertical height of the bottom of 10 is 100mm, 6 φ110mm holes are evenly opened, and the φ108mm×300mm long ore unloading pipe 9 is welded; 2mm thin plate is cut with specifications of 4800mm long×480mm wide to make the upper cover 3, and the lock buckles 2 are welded on both sides of the length direction, and the lock buckles 2 are welded in the corresponding length direction of the trough body 10, and the upper cover 3 and the trough body 10 are locked with M16 bolts, and the φ160mm upper cover opening 4 is cut at the corresponding position of the ore feeding pipe 1 passing through the upper cover 3 to ensure that the φ159mm ore feeding pipe 1 passes through the upper cover 3 and enters the buffer zone 6 of the trough body.

[0016] Working principle: During the operation of the filter, the slurry passes through the ore feeding pipe 1 through the opening 4 of the upper cover, enters the tank body 10, and enters the buffer zone 6 after being deslagging by the white steel grate 5. The impact force of the slurry is reduced, and as the liquid level rises steadily, it passes over the partition 7 and enters the unloading area 8, and is then discharged through the unloading pipe 9 and enters the mixing area of ​​the filter for dehydration.

[0017] The above description is only a specific implementation of the present utility model, and various examples do not constitute a limitation on the essential content of the present utility model.
