Description

Technical Field

[0001] This utility model relates to the technical field of copper electrolysis equipment, and in particular to an impurity separation device for the discharge port of anode mud in an electrolytic cell. Background Technology

[0002] In the PC copper electrolysis production process, anode sludge is generated at the anode. When the cathode copper production is completed according to the cycle schedule, the anode and cathode need to be removed, and then all the electrolyte is drained and the bottom of the tank is cleaned. The supernatant enters the supernatant storage tank, is filtered, and then returned to the circulation system. The anode sludge at the bottom of the tank needs to be flushed out of the electrolytic cell. In existing technology, the anode sludge is generally discharged outside the tank through a drain hose. However, the anode sludge contains a large number of large particles and plate-like anode residues, which easily clog the drain hose when passing through it. Therefore, the drain hose needs to be frequently dredged and cleaned. The anode mud from the tube can enter the pit, and after mechanical stirring, it is pumped to the thickener by the pit pump. After being filtered, the electrolyte is returned to the circulation system. When the hose becomes blocked, it is usually cleared by a stainless steel rod. During the clearing process, the rubber hose is easily punctured by the stainless steel rod, causing the anode mud in the electrolytic cell to spill onto the ground below the tank. When the hose is completely blocked, it needs to be cut open and cleared in reverse from below the tank. The electrolyte in the tube can also easily splash onto the workers, causing burns and scalds, which poses a safety hazard. Therefore, the process of cleaning and clearing the drain hose is inconvenient. Utility Model Content

[0003] This invention proposes an impurity separation device for the discharge port of anode mud in an electrolytic cell, aiming to solve the problem of easy blockage of the discharge pipe when discharging anode mud from an electrolytic cell in the prior art.

[0004] The technical solution adopted by the utility model is: an impurity separation device for the discharge port of anode mud in an electrolytic cell, comprising: a filter head, the filter head comprising a conical body, the conical body being hollow and having a plurality of filter ports on its surface for filtering impurities in the anode mud, the small-diameter end of the conical body being disposed inside the discharge port of the anode mud in the electrolytic cell; and a fixing rod, the fixing rod being disposed at the large-diameter end of the conical body.

[0005] Furthermore, the fixing rod is detachably connected to the conical body.

[0006] Furthermore, a first connecting block is provided on the large-diameter end of the conical body, and a second connecting block is provided at one end of the fixing rod that is threadedly connected to the first connecting block.

[0007] Furthermore, the filter head and / or fixing rod are made of 316L stainless steel.

[0008] Furthermore, both the large-diameter end and the small-diameter end of the conical body are annular rings, and the annular rings at the large-diameter end and the annular rings at the small-diameter end are connected and fixed by a number of first rods, and the gap between the first rods is the filter port.

[0009] Furthermore, a plurality of second rods are provided inside the annular ring at the large-diameter end of the conical body, and the gap between the second rods forms the filter opening.

[0010] Furthermore, the second rod is provided with a nut, and the end of the fixing rod is provided with a bolt that matches the nut.

[0011] Compared with existing technologies, this invention inserts the small-diameter end of the filter head into the discharge port of the electrolytic cell, while the large-diameter end remains exposed outside the discharge port. During the discharge of anode sludge, the anode sludge can be discharged through the filter port on the filter head, while large particles of impurities are retained inside the electrolytic cell. This pre-separates the anode sludge and impurities, preventing impurities from entering the anode sludge hose at the bottom of the cell and thus solving the problem of impurities clogging the hose. On the one hand, this saves water, shortens the cleaning time, and improves work efficiency; on the other hand, it prevents impurities from clogging the anode sludge pipes below the cell, reducing the danger to personnel during cleaning.

[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] This application proposes an impurity separation device for the discharge port of anode mud in an electrolytic cell, combined with an attached... Figure 1 , 4 As shown, the impurity separation device consists of two parts: a filter head 1 and a fixing rod 3. The filter head 1 is conical and hollow, with a filter port 2 on its surface. The size of the filter port 2 can be adjusted according to actual needs. Its purpose is to allow only anode mud to pass through the filter head 1, while separating large particles and flaky electrode residues, thus preventing impurities from entering the discharge port and the hose connected to the discharge port, thereby preventing hose blockage at the source. The fixing rod 3 is connected to the large-diameter end of the conical body. The fixing rod 3 is relatively long so that during the discharge of anode mud, the operator can hold the fixing rod 3 outside the electrolytic cell to fix the filter head 1 or use an auxiliary mechanical mechanism to fix and press the fixing rod 3, thereby ensuring that the filter head 1 is stably set at the discharge port.

[0020] Example 1

[0021] In Embodiment 1, both the filter head 1 and the fixing rod 3 are designed in a simplified manner, combined with the attached... Figures 1 to 3 As shown, in this embodiment: the filter head 1 includes a conical body, which is composed of three parts: a large-sized annular ring 6, a small-sized annular ring 6, and several first rods 7. The large-sized annular ring 6 and the small-sized annular ring 6 are both bent from 8mm steel pipes. The small-sized annular ring 6 has a diameter of 60mm, and the large-sized annular ring 6 has a diameter of 120mm. The first rods 7 are made of stainless steel with a length of 200mm and a diameter of 3mm. The conical body with a filter port 2 is formed by welding and fixing the large-sized annular ring 6 and the small-sized annular ring 6 together with 22 first rods 7. The gap between the first rods 7 is the filter port 2.

[0022] In addition, several second rods 8 are provided inside the large annular ring 6. The gap between these second rods 8 and the second rods 8 also forms a filter port 2, and the fixing rod 3 is connected to the second rods 8.

[0023] Furthermore, in this embodiment, the fixing rod 3 and the large-sized annular ring 6 can be fixed by welding or by detachable connection. The fixing rod 3 and the conical body can be detachably fixed by threaded connection. For example, a first connecting block 4 is provided on the large-diameter end of the conical body, and a second connecting block 5 is provided on one end of the fixing rod 3, which is threaded to the first connecting block 4. The first connecting block 4 is a nut, and the second connecting block 5 is a bolt. The nut and the bolt are compatible to realize the threaded connection between the fixing rod 3 and the conical body, so as to improve the applicability and flexibility of the entire separation device. Different lengths of fixing rod 3 can be replaced according to different usage requirements. The fixing rod 3 can be a stainless steel pipe with a length of 1800mm and a diameter of 20mm.

[0024] Example 2

[0025] The main difference between Example 2 and Example 1 lies in the different design of filter head 1, such as... Figure 4 As shown, in Embodiment 2, the filter head 1 is designed as a single piece. The surface of the filter head 1 is composed of a plate, and the interior forms a hollow cup structure. One end of the filter head 1 has a larger diameter (120mm), while the other end has a smaller diameter (60mm). In this case, simply placing the filter head 1 at the discharge port can separate impurities from anode mud, preventing impurities from entering the hose and causing blockage. The first connecting block 4 can then be directly fixed to the large-diameter end piece. The design of the fixing rod 3 is the same as in Embodiment 1, and will not be described again here.

[0026] Preferably, the filter head 1 and / or the fixing rod 3 in this invention can both be made of 316L stainless steel, thereby improving the service life of the impurity separation device and ensuring structural strength.

[0027] During use, workers insert the smaller diameter end of the filter head 1 into the discharge port of the electrolytic cell by holding the fixed rod 3 or its end. The larger diameter end can remain outside the discharge port. During the discharge of anode mud, the anode mud can be discharged through the filter port 2 on the filter head 1, while large particles of impurities are retained in the electrolytic cell. This separation of anode mud and impurities in advance prevents impurities from entering the anode mud hose at the bottom of the cell, thus solving the problem of impurities clogging the hose. On the one hand, this saves water and shortens the cleaning time, improving work efficiency; on the other hand, it prevents impurities from clogging the anode mud pipes below the cell, reducing the danger to personnel during cleaning.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
