Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of filtrate tanks, in particular to a filtrate tank for preventing ore accumulation. Background Art
[0002] The filtrate pool is used for a long time in the process of concentrate filtration. The filtrate water from the filter press, the flushing water of the plant, and the leakage during the production process will all reach the filtrate pool; in the production process, the slurry is settled by the thickener and then transported to the filter press for filtration. The filter press intercepts the minerals through the filter cloth, and the water passes through the filter cloth into the filtrate pool. In this process, some very small-sized minerals can pass through the filter cloth and enter the filtrate pool with the water; in addition, leakage of the filter press often occurs, and these leaking liquids eventually flow into the filtrate pool; these two aspects lead to serious mineral accumulation in the filtrate pool.
[0003] In view of the above situation, when the slurry pump is directly used to extract the accumulated ore, on the one hand, the precipitated accumulated ore is easy to float upward; on the other hand, the extraction of the accumulated ore in the filtrate pool far away from the slurry pump is not ideal, and manual assistance is required for cleaning; and when cleaning manually, the accumulated ore in the pool can only be carried out after the system is stopped, but under actual working conditions, the filtrate pool needs to be in operation for a long time, and it is not practical to stop the filtrate pool. Even if it can be stopped for cleaning, the accumulated ore will be pressed against the lower layer after long-term sedimentation, and the efficiency of manual cleaning is low and the labor intensity is high. And from the root, as long as the accumulation of ore in the filtrate pool can be solved, there is no need to spend money on cleaning.
[0004] Based on the problems in the above-mentioned background technology, the staff proposed a filtrate pool for preventing ore accumulation. Utility Model Content

Under the action of the spring, the vibration time of the guide plate is prolonged, the vibration area is diffused, and the vibration intensity is reduced, thereby preventing ore accumulation.
[0009] Furthermore, a plurality of inverted V-plates are arranged side by side on the upper part of the group of guide plates, and the top of the guide plate is hinged to the tops of the plurality of inverted V-plates through an L-shaped connector to ensure a stable structure.

[0013] Furthermore, the push plate is connected to a telescopic power mechanism via a driving shaft, and the telescopic power mechanism provides power for the push plate.

DETAILED DESCRIPTION
[0020] The structure and working principle of the present utility model are specifically described below through various embodiments.
[0021] Example 1
[0022] Please refer to Figures 1 to 3, a filtrate pool for preventing ore accumulation includes a pool body 1; a guide block 2 arranged in the pool body 1, a lower outlet 5 arranged at the lower part of the outer wall of the pool body 1; a telescopic power mechanism 4 arranged outside the pool body 1 and located above the lower outlet 5; the following describes the filtrate pool structure in this example around the main components:
[0023] 1. Guide block 2;
[0024] The guide blocks 2 have a triangular cross section and are arranged in groups at the bottom of the pool body 1 . The symmetrical guide blocks 2 form a U-shaped inclined surface with a slanted mouth at the bottom of the pool body 1 .
[0025] A push plate 3 is provided between the guide blocks 2. The push plate 3 is adapted to the shapes of the guide blocks 2 and the bottom surface of the pool body 1 and can slide freely therebetween.
[0026] 2. Telescopic power mechanism 4;
[0027] The driving shaft 16 of the telescopic power mechanism 4 passes through the pool body 1 and is connected to the push plate 3. During its movement, it can drive the push plate 3 to slide back and forth on the bottom wall of the pool body 1 between the guide blocks 2 to scrape the slag. The mixture of fine minerals and water precipitated in the pool body 1 is scraped to prevent ore accumulation.
[0028] The telescopic power mechanism 4 adopts a powerful electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod.
[0029] Select the high-power electric hydraulic push rod from Shandong Pumei Intelligent Equipment Co., Ltd.
[0030] 3. Lower outlet 5;
[0031] The lower discharge port 5 is connected to a slurry pump 6 through a pipeline for extracting the mixture of fine minerals and water scraped by the push plate 3 .
[0032] The combination of the above components can preliminarily prevent ore accumulation in the filtrate pool, but there is still a defect, that is, when the push plate 3 scrapes between the guide block 2 and the pool body 1, the precipitated ore is easy to float upward, and the extraction of ore far away from the slurry pump 6 is not ideal.
[0033] Therefore, further improvements are made in Example 2.
[0034] Example 2
[0035] On the basis of embodiment 1, it further includes a guide plate 7 and an inverted V-shaped plate 11 arranged in the pool body 1, and an upper discharge port 13 arranged in the middle of the outer wall of the pool body 1.
[0036] The following describes the filtrate pool structure in this example with focus on the main components newly added in this example:
[0037] 4. Guide plate 7
[0038] The guide plates 7 are arranged in groups tilted downward, and are each provided with a plurality of groups of spring shafts 9 at the bottom. The inner wall of the pool body 1 is symmetrically provided with limit plates 8. The spring shafts 9 are located between the limit plates 8 and the guide plates 7 and are sleeved with springs 10. The spring shafts 9 penetrate the limit plates 8 and can move up and down in the limit plates 8 when the springs 10 are deformed.
[0039] When the guide plate 7 encounters water and mineral particles falling at different positions, the local position of the guide plate 7 is randomly compressed, causing deformation to be transmitted to the spring shaft 9, and the spring shaft 9 moves downward. After the limit plate 8 blocks the spring 10, the spring 10 is compressed; when the pressure at the local position disappears, the spring 10 rebounds in the opposite direction.
[0040] In the above process, the random compressed positions of the guide plate 7 are vibrated for a longer time, with a wider vibration area and a reduced vibration intensity under the action of the spring 10. This can form continuous micro-vibrations at different positions on the surface of the guide plate 7, prevent ore accumulation, and avoid unstable vibrations at local positions of the guide plate 7 when encountering large flow rates.
[0041] 5. Inverted V plate 11;
[0042] Multiple inverted V plates 11 are arranged side by side on the upper part of the group of guide plates 7, and the top of the guide plate 7 is hinged to the top of multiple inverted V plates 11 through an L-shaped connecting piece 12. Specifically, the L-shaped connecting piece 12 is hinged to the plate surface of the guide plate 7 and the local position of the plate surface of the inverted V plate 11.
[0043] In order to further stabilize the connection and transmit vibration, a spring rod 15 is provided at a position near the end of the bottom of the guide plate 7 and the top of the inverted V plate 11.
[0044] Different positions of the inverted V-plate 11 will randomly encounter water and particulate minerals falling, and its local positions will also be randomly compressed. This pressure will be transmitted in two places. One is transmitted to the guide plate 7 through the connecting piece 12; the other is transmitted to the guide plate 7 through the spring rod 15; when the pressure disappears, due to the reverse rebound of the spring 10 and the spring rod 15, the guide plate 7 and the inverted V-plate 11 will vibrate.
[0045] In this process, the spring rod 15 not only plays a role in pressure transmission, but also plays a role in fixing the inverted V-plate 11, and cooperates with the connecting piece 12 to ensure that the inverted V-plate 11 will not loosen or deviate when the flow rate of fine minerals and water is large.
[0046] Multiple groups of inverted V plates 11 are arranged side by side, and cooperate with the guide plate 7 to prevent the precipitated ore from drifting upward when the push plate 3 scrapes between the guide block 2 and the pool body 1, and can largely block the fine minerals at the bottom, which is convenient for the slurry pump 6 to extract.
[0047] 6. Upper row port 13;
[0048] The upper discharge port 13 is connected to a clear liquid pump 14 through a pipeline for extracting the clear liquid above the inverted V-plate 11 and the guide plate 7 .
[0049] The operation process of this embodiment is as follows:
[0050] After the slurry is settled by the thickener and filtered by the filter press, the mixture of fine minerals and water enters the pool body 1 of the utility model through the filter cloth.
[0051] It first falls onto the guide plate 7 and multiple inverted V plates 11, causing vibration. Under the action of the spring 10 and the connector 12, and in conjunction with the function of the spring rod 15, the vibration is evenly transmitted to the surface of the guide plate 7 and the surface of the inverted V plate 11, preventing the guide plate 7 and the inverted V plate 11 from accumulating ore, so that the fine minerals fall along the inclined surface of the guide plate 7, the inclined surfaces of multiple inverted V plates 11, and the gaps between the inverted V plates 11.
[0052] The mixture of fine minerals and water continues to fall to the inclined surface of the guide block 2 and the bottom of the pool body 1. The telescopic power mechanism 4 is opened at regular intervals to drive the push plate 3 to scrape the slag back and forth to prevent ore accumulation.
[0053] In this embodiment, it is found through empirical observation that:
[0054] The slurry pump 6 on the upper discharge port 13 is opened every 3 hours to extract the clear liquid. There is also a very small amount of fine minerals in the clear liquid, but it does not affect its reuse in the grinding stage; the slurry pump 6 on the lower discharge port 5 is opened every 9 hours to extract the slurry composed of fine minerals and water in the lower part of the pool body 1. During the pumping process, the fine minerals are not easy to float upwards because the guide plate 7 and the inverted V plate 11 can play a blocking role; considering that the fine minerals in the lower part of the pool body 1 can be filtered through the filter press, they are no longer recycled to the front end of the filter press, but are recycled separately.
[0055] It should be noted that if the thickener and filter press equipped at the front end of the pool body 1 have high power and the filtered fine minerals and water flow are large, it is necessary to appropriately increase the width and thickness of the inverted V-plate 11 and the connector 12, or even reinforce the end of the L-shaped connector 12 to ensure its appropriate strength.
