Description

Technical Field

[0001] This utility model relates to the field of negative electrode aluminum foil production technology, specifically to a water inlet device for an etching tank used in the production of negative electrode aluminum foil. Background Technology

[0002] In the production of negative electrode aluminum foil, in order to achieve stable production control, a certain amount of water needs to be added to the etching tank to adjust the concentration balance of the tank solution. Traditional water inlet devices directly add water to the reaction tank through pipes, and the water flow rate cannot be adjusted. When the water flow rate is too fast, it may cause uneven local temperature and tank solution concentration, affecting the quality of the aluminum foil after production. Therefore, a water inlet device for etching tanks in the production of negative electrode aluminum foil is proposed to solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The purpose of this invention is to solve the problem that traditional water inlet devices directly add water to the reaction tank through pipes, and the water flow rate cannot be adjusted. When the water flow rate is too fast, it may cause uneven local temperature and tank solution concentration, affecting the quality of aluminum foil after production. Therefore, this invention proposes a water inlet device for corrosion tanks in the production of negative electrode aluminum foil.

[0005] (II) Technical Solution

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A water inlet device for an etching tank used in the production of negative electrode aluminum foil includes a three-way pipe. The inner diameter of the main chamber of the three-way pipe is larger than the inner diameter of the two connecting ports and the lower water outlet. The bottom end of the three-way pipe is connected to a water outlet pipe, and the end of the water outlet pipe is fixedly connected to a nozzle. The nozzle has several water outlet holes. The top end of the three-way pipe is provided with an adjustment component for adjusting the water output of the nozzle.

[0008] The adjustment assembly includes support rods. Two support rods are fixedly connected to the top of the three-way pipe. The outer sides of the two support rods are fixedly connected to threaded sleeves. A screw is threadedly connected to the inner side of the threaded sleeve. A handwheel is fixedly connected to the top of the screw. A connecting rod is fixedly connected to the bottom of the screw, with one end penetrating and extending into the inner side of the three-way pipe. An adjustment disc is fixedly connected to the bottom of the connecting rod. A sealing plug is fixedly connected to the bottom of the adjustment disc. The sealing plug fits into the inner wall of the outlet below the three-way pipe.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Preferably, the two connecting ports of the tee pipe and the outer side of the lower outlet are each provided with three flanges.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] This invention utilizes a threaded sleeve, a screw, a handwheel, and a sealing plug. First, rotating the handwheel causes the screw to rotate, moving it downwards along the center line of the threaded sleeve. This causes the sealing plug to move downwards, creating a small enough gap between the sealing plug and the outlet below the tee pipe. This ensures that the water flows slowly from the nozzle, preventing uneven local temperature and solution concentration, which could negatively impact the quality of the produced aluminum foil.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the embodiments, by Figure 1 and Figure 2 A water inlet device for an etching tank used in the production of negative electrode aluminum foil is provided, comprising a three-way pipe 1, wherein the inner diameter of the main chamber of the three-way pipe 1 is larger than the inner diameter of the two connecting ports and the lower water outlet, the bottom end of the three-way pipe 1 is connected to a water outlet pipe 2, the end of the water outlet pipe 2 is fixedly connected to a nozzle 3, the nozzle 3 is provided with a plurality of water outlet holes 4, and the top end of the three-way pipe 1 is provided with an adjustment component 5 for adjusting the water output of the nozzle 3.

[0019] The adjusting assembly 5 includes support rods 51. Two support rods 51 are fixedly connected to the top of the three-way pipe 1. The outer sides of the two support rods 51 are fixedly connected to threaded sleeves 52. The inner side of the threaded sleeves 52 is threaded with a screw 53. A handwheel 54 is fixedly connected to the top of the screw 53. A connecting rod 55 with one end penetrating and extending to the inside of the three-way pipe 1 is fixedly connected to the bottom of the screw 53. An adjusting disc 56 is fixedly connected to the bottom of the connecting rod 55. A sealing plug 57 is fixedly connected to the bottom of the adjusting disc 56. The sealing plug 57 fits into the inner wall of the outlet below the three-way pipe 1.

[0020] With the above settings, connect the two ports of the three-way pipe 1 to the water inlet pipe, which can supply water to the three-way pipe 1. First, turn the handwheel 54 to make the screw 53 rotate accordingly. The screw 53 moves downward along the center line of the threaded sleeve 52, causing the sealing plug 57 to move downward, leaving a gap between the sealing plug 57 and the water outlet below the three-way pipe 1. The gap is small enough to ensure that the water flows slowly when it is sprayed from the nozzle 3, avoiding uneven local temperature and bath concentration, which would affect the quality of the aluminum foil after production.

[0021] Reference Figure 1 and Figure 2 Among them, three flanges 6 are provided on the two connecting ports of the three-way pipe 1 and on the outside of the lower outlet;

[0022] With the above structural design, flange 6 serves as a connection and can be used to connect water outlet pipe 2 and two water inlet pipes.
