Technical Field
The invention belongs to the technical field of design of ore dressing plants, and particularly relates to a gravity drainage arrangement method of a filter.
Background
The filtration process of the concentrating mill usually adopts a vacuum disc filter, the stable vacuum degree of the filter is a key parameter of the production effect of the filter, a vacuum pump is generally adopted to be matched with a gravity drainage tank in production to ensure the requirement of filtration vacuum, a filtrate pipe of the gravity drainage tank adopts water seal, and the height difference of at least 9m is required to ensure that the filtrate can be continuously discharged. Therefore, the filter in the filtering workshop needs to be arranged on a platform of 9m or 10m, the height difference of the workshop is increased, and the investment is large.
Disclosure of Invention
The invention aims to provide a gravity drainage arrangement method of a filter, which reduces the platform of the filter and a gravity drainage tank and reduces the cost of a filter workshop.
The purpose of the invention is realized by the following technical scheme:
the gravity drainage arrangement method of the filter is characterized by comprising the following steps of:
(1) arranging a vacuum disc filter arrangement and a gravity liquid discharge tank connected with the vacuum disc filter on a platform with the bottom elevation of 6m, wherein the upper part of the gravity liquid discharge tank is connected with a vacuum pump;
(2) arranging a water seal pool at the position with the bottom elevation of-3.50 m, arranging an overflow pool in the water seal pool, arranging a vertical slurry pump in the overflow pool, and arranging a liquid level meter in the water seal pool;
(3) filtrate automatically flows into a gravity drainage tank from the vacuum disc filter, the air at the upper part of the gravity drainage tank is connected with a vacuum pump, and the filtrate at the lower part is discharged into a water seal tank through a filtrate pipeline;
(4) the elevation of the bottom of the water seal pool is 3.50m below zero, the height difference of the water seal pool is controlled by the overflow surface to be stable, the overflow enters the overflow pool, the vertical slurry pump is controlled by the liquid level meter to discharge liquid, and high-pressure washing water is arranged in the overflow pool to prevent minerals in filtrate from precipitating and blocking the vertical slurry pump.
And the bottom of the water seal tank is adjusted according to the heights of the vacuum disc filter and the gravity liquid discharge tank platform.
The volumes of the water seal tank and the overflow water tank are set according to the actual process requirements.
The invention has the advantages that:
according to the gravity drainage arrangement method of the filtering machine, a water seal box on a 0m terrace is omitted, the water seal pool is arranged, the overflow of the water seal pool enters an overflow water pool, drainage is carried out by a vertical slurry pump controlled by the height and the lower liquid level of a liquid level meter, the gravity drainage tank and the filtering machine are arranged on a platform about 6m, the height of a mounting platform of the filtering machine can be adjusted according to the depth of the pump pool, the height of the whole workshop is reduced, and the occupied area of the water seal pool is very small, so that the investment of the whole filtering workshop is greatly reduced.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in figure 1, the gravity drainage arrangement method of the filter is characterized by comprising the following steps:
(1) a vacuum disc filter 1 and a gravity liquid discharge tank 2 connected with the vacuum disc filter 1 are arranged on a platform with the bottom elevation of 6m, and the upper part of the gravity liquid discharge tank is connected with a vacuum pump 7;
(2) arranging a water seal tank 3 at the position with the bottom elevation of-3.50 m, arranging an overflow water tank 4 in the water seal tank 3, arranging a vertical slurry pump 5 in the overflow water tank 4, and arranging a liquid level meter 6 in the water seal tank 3;
(3) filtrate automatically flows into a gravity liquid discharge tank 2 from a vacuum disc filter 1, the air at the upper part of the gravity liquid discharge tank 2 is connected with a vacuum pump 7, and the filtrate at the lower part is discharged into a water seal tank 3 through a filtrate pipeline;
(4) the elevation of the bottom of the water seal pool 3 is minus 3.50m, the height difference of the water seal pool 3 is controlled by the overflow surface to be stable, the overflow enters the overflow pool 4, the vertical slurry pump 5 is controlled by the liquid level meter 6 to discharge liquid, and the high-pressure washing water 8 is arranged in the overflow pool 4 to prevent the mineral precipitation in the filtrate from blocking the vertical slurry pump 5.
The bottom of the water seal tank 3 is adjusted according to the platform heights of the vacuum disc filter 1 and the gravity liquid discharge tank 2.
The volumes of the water seal tank 3 and the overflow water tank 4 are set according to the actual process requirements.
The arrangement form of the invention has safe and reliable operation, meets the requirement of a vacuum system of the filter, reduces the problem of overhigh installation of the filter in production and reduces the investment. According to the invention, a water seal box on a 0m floor is cancelled, the water seal pool 3 is arranged, the overflow of the water seal pool 3 enters an overflow water pool 4, liquid is discharged by a liquid level meter 6 for controlling the height of a vertical slurry pump 5, at the moment, a gravity liquid discharge tank 2 and a vacuum disc filter 1 are arranged on a platform about 6m, the height of the installation platform of the vacuum disc filter 1 can be adjusted according to the depth of a pump pool, the height of the whole plant is reduced, and the investment of the whole filtering workshop is greatly reduced because the water seal pool occupies a small area.
