Description

Technical Field

[0001] This application relates to the field of zinc electrowinning smelting technology, and in particular to a liquid feeding device for a zinc electrowinning electrolytic cell. Background Technology

[0002] In the zinc electrowinning smelting process, the liquid inlet chute in the zinc electrowinning workshop is typically made of square fiberglass or round PP pipe. Then, a fiberglass round pipe or a plastic round pipe is connected to guide the circulating liquid into the electrolytic cell. The round pipe usually requires an additional inlet device to prevent leakage of the circulating liquid.

[0003] During production, a guide channel is usually installed at the bottom of the circular pipe to guide the circulating liquid. However, when the circulating liquid enters the electrolytic cell, it directly impacts the anode / cathode plates inside the cell. Over time, calcium sulfate crystals will form on the plate surface, resulting in a decrease in the conductivity of the plates. Utility Model Content

[0004] To solve or partially solve the problems existing in the related technologies, this application provides a liquid feeding device for a zinc electrolytic cell.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A liquid feeding device for a zinc electrowinning electrolytic cell includes a fiberglass circular tube and a liquid feeding chute wall. The liquid feeding device for the zinc electrowinning electrolytic cell further includes:

[0007] The guide channel is fixed on the wall of the liquid inlet chute and located below the fiberglass round tube;

[0008] The trough cover, which is fitted into the flow channel, is composed of two side plates, a top plate, and a baffle.

[0009] The side plate is connected to the side of the guide channel, the top plate is located above the fiberglass round tube and covers the fiberglass round tube, and the cover extends outside the guide channel along the flow direction of the guide channel so that the baffle blocks the fluid.

[0010] Optionally, the side plate is hinged to the side of the guide channel so that the channel cover can rotate relative to the guide channel.

[0011] Optionally, the hinge joint between the side plate and the guide channel is locked with a nut.

[0012] Optionally, the top plate is provided with an arc-shaped groove that is compatible with the fiberglass tube, so that the top plate does not come into contact with or interfere with the fiberglass tube when the groove cover rotates.

[0013] Optionally, an electric telescopic rod is provided between the top plate and the wall of the liquid inlet chute. The fixed end of the electric telescopic rod is hinged to the wall of the liquid inlet chute through a first hinge seat, and the movable end of the electric telescopic rod is hinged to the top plate through a second hinge seat.

[0014] Optionally, the first hinge seat is connected to the wall of the liquid inlet chute by a first mounting plate screw, and the second hinge seat is connected to the top plate by a second mounting plate screw.

[0015] Optionally, the guide channel and the cover are made of vinyl ester resin fiberglass.

[0016] The beneficial effects of this application are as follows: A gap is formed between the bottom of the tank cover and the guide channel. When the circulating liquid flows out through the fiberglass round pipe and the guide channel, the circulating liquid encounters the baffle, which blocks it, so that the circulating liquid flows into the zinc electrolytic cell along the gap. This avoids the circulating liquid directly impacting the anode / cathode plate surface when it flows, thereby reducing the crystallization on the plate surface and enhancing the conductivity of the plate.

[0031] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0032] Example 1:

[0033] See Figure 1 and Figure 2 A liquid feeding device for a zinc electrolytic cell includes a fiberglass circular tube 1 and a liquid feeding chute wall 2. The liquid feeding device for the zinc electrolytic cell further includes:

[0034] The guide channel 3 is fixed on the wall 2 of the liquid inlet chute and located below the fiberglass round tube 1;

[0035] The trough cover 4, which is fitted into the guide channel 3, is formed by two side plates 5, a top plate 6, and a baffle 7.

[0036] The side plate 5 is connected to the side of the guide channel 3, the top plate 6 is located above the fiberglass round tube 1 and covers the fiberglass round tube 1, and the cover 4 extends out of the guide channel 3 along the flow direction of the guide channel 3 so that the baffle 7 blocks the fluid.

[0037] Specifically, for ease of explanation, only the inlet sluice wall 2 is shown in the figure, and the entire inlet sluice is not shown. The inlet sluice wall 2 is part of the inlet sluice. The fiberglass round tube 1 is installed on the inlet sluice wall 2, and the circulating liquid inside the sluice flows out through the fiberglass round tube 1. One end of the guide channel 3 is fixed to the inlet sluice wall 2, and its two sides are higher than the fiberglass round tube 1. Its bottom is located below the fiberglass round tube 1 to receive the circulating liquid flowing out of the fiberglass round tube 1.

[0038] The guide channel 3 is larger than the cover 4 to facilitate its fitting. The cover 4 is composed of two side plates 5, a top plate 6, and a baffle 7. The side plates 5 are connected to the sides of the guide channel 3, and the top plate 6 is opposite to the bottom of the guide channel 3. The top plate 6 is positioned above and covers the fiberglass tube 1. The cover 4 and the guide channel 3 are integrally formed to enhance structural strength. Below the cover 4 is a zinc electrolytic cell.

[0039] The tank cover 4 extends out of the guide channel 3 along the flow direction of the guide channel 3. In this way, a gap 15 is formed between the bottom of the tank cover 4 and the guide channel 3. When the circulating liquid flows out through the fiberglass round pipe 1 and the guide channel 3, the circulating liquid encounters the baffle 7, which blocks it, so that the circulating liquid flows into the zinc electrolytic cell along the gap 15. This avoids the circulating liquid directly impacting the anode / cathode plate surface when it flows, thereby reducing the crystallization on the plate surface and enhancing the conductivity of the plate.

[0040] Furthermore, since the traditional flow channel 3 lacks a cover, the mutual impact between liquids can cause leakage, resulting in significant environmental hazards. This application solves the leakage problem by providing a cover 4 and embedding it into the flow channel 3 to achieve a sealing effect, thereby avoiding environmental hazards.

[0041] Example 2:

[0042] See Figure 2 and Figure 3 Based on Embodiment 1, optionally, the side plate 5 is hinged to the side of the guide channel 3 so that the cover 4 can rotate relative to the guide channel 3.

[0043] Specifically, the hinge between the side plate 5 and the guide channel 3 enables the trough cover 4 to rotate relative to the guide channel 3, thereby facilitating the opening and closing of the trough cover 4 and ensuring that the operator can easily open the trough cover 4 when cleaning the fiberglass round tube 1.

[0044] Optionally, the hinge joint between the side plate 5 and the guide groove 3 is locked by a nut 8.

[0045] Specifically, the tightness between the side plate 5 and the guide channel 3 is ensured by the nut 8. When the channel cover 4 needs to be opened, the nut 8 can be loosened. Before the guide operation, the nut 8 is tightened to avoid the channel cover 4 becoming unstable during the guide operation, which could cause leakage.

[0046] Optionally, the top plate 6 is provided with an arc-shaped groove 9 that is adapted to the fiberglass tube 1 so that when the groove cover 4 rotates, the top plate 6 does not come into contact with or interfere with the fiberglass tube 1.

[0047] Specifically, since there are two fiberglass round tubes 1, two arc-shaped grooves 9 are also correspondingly provided. During the rotation of the groove cover 4, the outer wall of the fiberglass round tube 1 gradually fits into the arc-shaped groove 9, thus avoiding interference between the top plate 6 and the fiberglass round tube 1 and ensuring the normal opening and closing of the groove cover 4.

[0048] Example 3:

[0049] See Figure 4 Based on the above embodiments, optionally, an electric telescopic rod 10 is provided between the top plate 6 and the inlet chute wall 2. The fixed end of the electric telescopic rod 10 is hinged to the inlet chute wall 2 through the first hinge seat 11, and the movable end of the electric telescopic rod 10 is hinged to the top plate 6 through the second hinge seat 12.

[0050] Specifically, considering that the opening and closing of the tank cover 4 requires loosening the nut 8 and then using the handle to drive the tank cover 4 to rotate, which wastes time, in this embodiment, an electric telescopic rod 10 is provided between the top plate 6 and the inlet chute wall 2, so that the two ends of the electric telescopic rod 10 are respectively hinged to the inlet chute wall 2 and the top plate 6, thereby realizing the opening and closing of the tank cover 4 by driving the electric telescopic rod 10. After using the electric telescopic rod 10, the nut 8 can be eliminated, and it is only necessary to ensure that the side plate 5 is hinged to the guide channel 3.

[0051] Optionally, the first hinge seat 11 is screwed to the inlet chute wall 2 via the first mounting plate 13, and the second hinge seat 12 is screwed to the top plate 6 via the second mounting plate 14.

[0052] Specifically, the screw connection method facilitates the installation and disassembly of the first hinge seat 11 and the second hinge seat 12, thereby facilitating the installation and disassembly of the electric telescopic rod 10.

[0053] Optionally, the guide channel 3 and the channel cover 4 are made of vinyl ester resin fiberglass.

[0054] Specifically, the flow guide trough 3 and the trough cover 4 are manufactured as follows:

[0055] S1: First, make the molds for the guide channel 3 and the channel cover 4, and polish the molds to ensure that the molds are clean and smooth;

[0056] S2: Apply a certain proportion of vinyl resin containing catalyst and accelerator evenly to the mold, and reinforce it with polyester fiber, chopped strand mat and glass fiber woven fabric from the inside out.

[0057] S3: The guide channel 3 and the cover 4 are made of vinyl ester resin fiberglass. The structure is made from the inside out as follows: anti-corrosion layer, anti-seepage layer, strength layer and outer surface layer.

[0058] S4: It is made by compression molding and UV protection agents are added to the resin to isolate it from the air and cure it to form a dense and uniform resin protective layer.

[0059] S5: Grind the fiberglass inlet chute and use fiberglass to bond the guide channel 3 and the inlet chute wall 2 together.

[0060] S6: Install the trough cover 4. The guide trough 3 and the trough cover 4 are hinged to facilitate the opening and closing of the trough cover 4.

[0061] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0062] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
