Technical Field

The invention discloses a catching device for clarifying indoor three-phase dirt by an extraction box, and particularly belongs to the technical field of hydrometallurgy.

Background

In the extraction production process, the aqueous phase feed liquid from the upstream leaching process and other processes often contains clay suspended particles, active silica and silicate colloids, dust particles in the air, insect corpses and other impurities. The impurity particles have specific wettability, are easy to strongly adsorb on an aqueous phase-organic phase interface, and are enriched in an interface emulsion after being flocculated by an organic phase to form three-phase dirt. In the shallow extraction box, after the water phase and the organic phase feed liquid are reacted by the mixing chamber, formed three-phase dirt generally appears between two phase interfaces in the clarification chamber. The composition of the three-phase soil is generally 5% to 15% solid phase, 40% aqueous phase, 40% organic matter, and 5% to 10% fourth phase inclusion particles.

The generation of three-phase dirt can cause the reduction of the extraction rate and the phase separation speed of metal ions, and further development of the three-phase dirt can increase the loss of an extracting agent and an organic solvent, cause water phase pollution and damage to a downstream process. At present, the traditional three-phase sewage catching method is to use a filter spoon and an oil drum to carry out single-point local manual catching and collecting, the sewage collected in the oil drum is intensively sent to an active clay stirring tank for treatment, and then sent to a centrifugal machine and other separation equipment to separate a solid phase, a water phase and an organic phase, wherein the regenerated water phase and the regenerated organic phase can be returned to an extraction system for recycling. However, manual fishing of three-phase dirt requires operators to have abundant production experience in the extraction section, and the operators need to be able to accurately identify the organic phase-aqueous phase interface generated by the three-phase dirt, so that effective fishing can be performed. In the fishing process, the disturbance to the liquid level of the clarification chamber is large, the extraction split-phase clarification effect is influenced, and the three-phase dirt is poured into the oil drum from the filter spoon, so that the secondary leakage is easy, the workshop environment is polluted, the safety is poor, the labor intensity is high, and the cost is high.

the frame (1) consists of an outer frame and an inner frame; the top ports of the four vertical rods of the outer frame are respectively provided with four limiting pulleys (5), and the bottom ports are respectively provided with four moving pulleys (6); the limiting pulley (5) is contacted with the limiting rope (2) through rolling, and the control wheel shaft (3) is contacted with the motion control rope (4) through rolling; the inner frame is covered with a gauze (7) to form a catching net cage, and the catching net cage and the outer frame form a complete three-phase dirt catching device;

the motion control rope (4) is driven to move by the operating wheel shaft (3), so that the fishing device can move back and forth in a bidirectional straight line in the clarifying chamber of the extraction box by means of four motion pulleys (6), and synchronously slide on the limit rope (2) in a limiting way by means of four limit pulleys (5); the catching device catches and collects three-phase dirt synchronously through a gauze (7) covered on the upper surface of the inner frame in the linear moving process of the clarifying chamber of the extraction box.

The outer frame is formed by connecting four vertical rods with four rods of the upper horizontal plane frame and the lower horizontal plane frame, wherein three rods are symmetrically arranged in two vertical side faces respectively, three parallel rods are symmetrically arranged in the upper horizontal plane frame, and one rod is arranged in the middle of the lower horizontal plane frame and is parallel to the three parallel rods in the upper horizontal plane frame; the inner frame is formed by connecting three parallel rods in the upper horizontal plane frame, four rods in the lower horizontal plane frame, a rod in the middle of the four rods and three rods in two vertical side surfaces.

The motion control rope (4) is fixedly connected with two symmetrical positioning points (8) in a horizontal plane frame on the frame (1). The outer dimensions of the frame (1) are adjusted according to the size of the fining chamber and the position of its a-O phase interface (11).

Example 2

The frame (1) of the fishing device is a cuboid framework formed by rods, and the outer frame of the fishing device is formed by connecting four vertical rods with four rods of the upper horizontal plane frame and the lower horizontal plane frame; three rods are symmetrically arranged in two vertical side surfaces of the rectangular framework respectively; three parallel rods are symmetrically arranged in the frame of the upper horizontal plane; a rod is arranged in the middle of the lower horizontal plane frame and is parallel to the three parallel rods in the upper horizontal plane frame; the top ports of the four vertical rods forming the outer frame are respectively provided with four limiting pulleys (5), and the bottom ports are respectively provided with four moving pulleys (6).

Three parallel rods in the upper horizontal plane frame, four rods of the lower horizontal plane frame, a rod in the middle of the four rods and three rods in two vertical side surfaces form a trapezoidal inner frame; the inner frame of the trapezoid body is covered with a gauze (7) to form a catching net cage, and the catching net cage and the outer frame form a complete three-phase dirt catching device.

The three-phase dirt catching device is supported by a moving pulley (6), limited by a limiting pulley (5) and a limiting rope (2) and driven by an operating wheel shaft (3) and a motion control rope (4).

Example 3

The movable range of the forward and backward movement of the fishing device is limited between the clarification chamber split-phase fences (10) at the left and right sides by a limiting rope (2), and the fishing device is shown in figure 5.

When the catching device sinks below the organic phase liquid level, the center of the catching net cage is positioned near the A-O phase interface (11) of the clarifying chamber, which is shown in figure 6.

The frame (1) of the fishing device is fixed with the motion control rope (4) in two points by a fixed point (8). During operation, the movement of the movement control rope (4) is controlled by using the control wheel shaft (3) fixed at the outer edge of the clarification chamber, so that the frame (1) is driven to move, and the fishing device moves forwards or backwards in two directions by means of the movement pulley (6), which is shown in figure 1.

Due to the limitation of the limiting rope (2) and the limiting pulley (5), the fishing device can only move in the linear direction, and when the fishing device slowly moves from one side of the clarifying chamber to the other side, three-phase dirt generated near an A-O phase interface is captured and collected by the gauze (7) covered on the frame (1). At the moment, the collected three-phase dirt can be sent to corresponding processing equipment for further separation processing only by inserting the three-phase dirt collecting pump pipeline into the net cage and sucking the three-phase dirt caught in the net cage.

Example 4

Examples of specific applications

8-thousand-ton extraction-electrodeposition wet-process copper smelting plant is produced in a certain year, the feed liquid used for extraction is stirred leach liquor containing more impurities such as silicon suspended matters, organic carbon and the like, and the feed liquid is mixed with organic phase to form white flocculent three-phase dirt mixed with emulsion and floats near the phase interface of a clarification chamber. The following problems are found in the process of catching three-phase dirt in a factory by using a traditional manual method:

1. ordinary operators with less experience cannot accurately identify the phase boundary, the fishing operation efficiency is low, and the clarification effect is disturbed because the liquid level of the clarification chamber is greatly disturbed.

2. The length and width of a single clarification chamber can reach 26m multiplied by 23m, and the long-handle filter spoon can not effectively touch the dirt far away from a fishing point.

3. Two series of the plant extraction workshop have 16 mixing clarification chambers, workers need to stand at a walkway at the top of the clarification chamber for fishing operation, and the plant extraction workshop has high labor intensity and low safety.

After the three-phase sewage is fished by the fishing device, the three-phase sewage is fished in the single clarification chamber, the three-phase sewage suspended near the phase interface can be put into the net cage only by controlling the fishing net cage to slowly move in the clarification chamber by a single worker through operating the operating wheel shaft (3), and when the fishing net cage moves to the edge of the clarification chamber, the three-phase sewage conveying pump pipeline is inserted, so that the three-phase sewage which is fished can be conveyed to the collecting tank without leakage. After the fishing device is used, the existing three-phase fishing labor order staff is reduced to 4 persons, and the labor intensity and the operation difficulty of fishing, loading, walking and other operations are greatly reduced.
