Description

Technical Field

[0001] This application relates to the technical field of cleaning, and particularly to a spray washing device for zinc smelting cathode plates. Background Art

[0002] There are two processes for zinc smelting: pyrometallurgy and hydrometallurgy. The closed blast furnace for lead and zinc smelting is the most important and almost the only pyrometallurgical zinc smelting method in the world. The main technological developments include increasing the treatment measures for secondary lead and zinc materials; improving the condensation efficiency; and applying oxygen enrichment technology, etc.

[0003] Hydrometallurgy is the most important zinc smelting method in the world today. After the zinc smelting cathode plates are taken out of the tank, they need to be cleaned to wash away the acid and other impurities carried on the plates, so as to ensure the quality of cathode zinc. In traditional technologies, a hot wash tank is usually used to clean the cathode plates. To ensure the hot wash effect, fresh water needs to be continuously replenished into the hot wash tank during the hot wash. Since the water used each time is not fresh water but a mixture of fresh water and sewage, the problem of unqualified cleaning quality of the cathode plates has occurred. Utility Model Content

[0035] In order to make the purpose, technical solutions, and beneficial effects of the present application clearer, the following will, with reference to the accompanying drawings, describe in detail the preferred embodiments of the present application to facilitate understanding by those skilled in the art.

[0036] Embodiment 1:

[0037] See Figures 1 to 3 , a zinc smelting cathode plate spraying and washing device, including a support 4, and the zinc smelting cathode plate spraying and washing device further includes:

[0038] A cross beam 1 provided at the top of the support 4, the inside of the cross beam 1 is hollow, and a water delivery pipe 2 is provided in the hollow part;

[0039] A number of spray heads 3 arranged at equal intervals on the inner side of the cross beam 1, and the spray heads 3 are communicated with the water delivery pipe 2;

[0040] Among them, there are two cross beams 1 and they are parallel to each other. The upper end surface of the cross beam 1 is provided with a W-shaped groove 5 for supporting the cathode plate.

[0041] Specifically, the top of the support 4 is fixedly connected to the bottom of the cross beam 1. There are supports 4 at the bottoms of both ends of the cross beam 1, and at least two pairs of supports 4 are provided. The interiors of the two cross beams 1 are hollow, and the water delivery pipe 2 is annularly fixed in the hollow parts of the two cross beams 1. A number of installation holes for installing the spray heads 3 are opened on the inner sides of the cross beams 1. The spray heads 3 are fixed to the inner sides of the cross beams 1 through the installation holes and are communicated with the water delivery pipe 2. The spray heads 3 can be adjusted according to the number of cathode plates to be cleaned, which can be 20, 22, and are not limited to 20 and 22. For example, they can be 24, 26, etc. There is a certain distance between the two cross beams 1, and this distance matches the width of the cathode plate. A number of W-shaped grooves 5 are provided, and the number thereof is not less than the number of cathode plates. The width of the W-shaped groove 5 matches the thickness of the cathode plate, so that the cathode plate can be snapped into the W-shaped groove 5. When the cathode plate is snapped into the W-shaped groove 5, a number of cathode plates span the cleaning space formed by the two cross beams 1, and are supported and fixed by the W-shaped groove 5.

[0042] During use, a number of cathode plates are snapped into the W-shaped groove 5, and the spray heads 3 are started. The high-pressure water flow sprayed by the spray heads 3 flushes the surface of the cathode plate to wash away the acid and other impurities carried on the plate. During the cleaning process, since the water flow sprayed by the spray heads 3 is always fresh water, each cathode plate can be continuously flushed by the fresh water source, and the sewage after cleaning flows away from the bottom of the device. Therefore, the problem of unqualified cleaning quality of the cathode plate caused by the mixing of fresh water and sewage is avoided.

[0043] Embodiment 2:

[0044] See Figures 1 to 4 , based on Embodiment 1, optionally, the zinc smelting cathode plate spraying and washing device further includes:

[0045] A photoelectric sensor arranged on the cross beam 1, the output end of the photoelectric sensor is electrically connected to a controller, and the controller has a timer.

[0046] Specifically, the photoelectric sensor includes a transmitter and a receiver, which are respectively installed on the path where the cathode plate passes, that is, on both sides of one end of the two cross beams 1. When the cathode plate enters the cleaning space formed by the two cross beams 1, the infrared signal sent by the transmitter is blocked, and the receiver cannot receive this signal, indicating that an object has passed. This detection signal is received by the controller. A cleaning time is preset in the timer, and this time is between 10 and 20 s.

[0047] Optionally, a solenoid valve is provided on the water delivery pipe 2, and the solenoid valve is electrically connected to the controller.

[0048] Specifically, the solenoid valve controls the flow and cut-off of the water flow. The controller sends an instruction to the solenoid valve to control its opening and closing. For different numbers of cathode plates, the preset cleaning time of the timer is different, as follows:

[0049] When the number of cathode plates is 20, the preset cleaning time in the timer is 10 s. Place 20 cathode plates in the W-shaped groove 5, start the spray head 3 for cleaning. After the cleaning is completed, lift the cleaned cathode plates out of the cleaning device by the trolley and enter the zinc stripping area to start the zinc stripping work;

[0050] When the number of cathode plates is 22, the preset cleaning time in the timer is 15 s. Place 22 cathode plates in the W-shaped groove 5, start the spray head 3 for cleaning. After the cleaning is completed, the trolley lifts the cleaned cathode plates out of the cleaning device and enters the zinc stripping area to start the zinc stripping work;

[0051] When the number of cathode plates is 23, the preset cleaning time in the timer is 20 s. Place 23 cathode plates in the W-shaped groove 5, start the spray head 3 for cleaning. After the cleaning is completed, the trolley lifts the cleaned cathode plates out of the cleaning device and enters the zinc stripping area to start the zinc stripping work.

[0052] In this embodiment, by setting different cleaning times for different numbers of cathode plates to improve the cleaning effect. In addition, the controller is used to precisely control the cleaning time. After the cleaning is completed, the spray washing device immediately stops spraying, which can effectively save water consumption.

[0053] Optionally, one end of the water delivery pipe 2 is connected with a pressure pump.

[0054] Specifically, water is sent into the water delivery pipe 2 by the pressure pump.

[0055] Optionally, the cross beam 1 is made of stainless steel.

[0056] Specifically, since the cross beam 1 is in contact with water for a long time, to avoid its oxidation and corrosion and enhance its service life, the cross beam 1 is made of stainless steel.

[0057] As Figure 4 shown, optionally, the spray head 3 is a spherical jet nozzle.

[0058] Specifically, the spherical jet nozzle can convert the water in the water delivery pipe 2 into a jet with a certain pressure and spray it out, thereby improving the cleanliness of the electrode plate.

[0059] Embodiment 3:

[0060] Refer to Figure 5 and Figure 6 , based on the above embodiments, optionally, the zinc smelting cathode plate spray washing device further includes a transfer bracket 6, and the transfer bracket 6 includes:

[0061] Two pairs of columns 7 are symmetrically arranged, a support rod 8 is fixed at the top of the column 7, and a W-shaped groove 5 for supporting the cathode plates to be cleaned is provided on the upper end surface of the support rod 8.

[0062] Specifically, the transfer bracket 6 is placed on one side of the cleaning device for temporarily storing the cathode plates to be cleaned. The cathode plates stored on the transfer bracket 6 are sent into the cleaning device by a crane for cleaning, and so on until all the cathode plates are cleaned.

[0063] It should be noted that the W-shaped groove 5 formed on the upper end surface of the support rod 8 is the same as the W-shaped groove 5 formed on the upper end surface of the cross beam 1, and no further description will be given here.

[0064] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application rather than to limit them. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in terms of form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical dimensions can be changed arbitrarily.
