Technical Field

[0001] The utility model relates to the technical field of liquid storage tanks, in particular to an iron-based etching liquid storage tank which is convenient for transportation. Background Art

[0002] Etching liquid is a raw material for copperplate engraving. It is a liquid that erodes the material's characteristics for engraving. Theoretically, any reagent that can oxidize steel to generate soluble copper salts can be used to etch copper-clad boards, but the damage to the anti-corrosion layer, etching speed, etching coefficient, copper dissolving capacity, solution regeneration and copper recovery, environmental protection and economic effects must be weighed. Metal etching liquid is required in the chemical etching process. Since metal etching liquid is made of chemical agents, and different chemical agents are required for different metal materials, particulate impurities may be precipitated during the chemical preparation process, and different chemical agents reacting with each other will also produce some particulate matter.

[0003] In the process of transporting etching liquid, a liquid storage tank is needed.

The tank transport device can reduce a lot of manpower and facilitate loading.

[0004] However, during use, the utility model, since the filter screen is located inside the metal etching liquid tank, although it can filter out impurities in the etching liquid, it cannot clean the filtered impurities, which affects the filtering effect and cannot meet production needs. Therefore, an iron-based etching liquid storage tank that is easy to transport is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that since the filter net is located inside the metal etching liquid tank, although the impurities in the etching liquid can be filtered out, the filtered impurities cannot be cleaned, which affects the filtering effect and cannot meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid storage tank for iron-based etching liquid that is easy to transport, comprising a mounting frame and a liquid storage tank body fixedly connected to the inside of the mounting frame, wherein a discharge filter structure extending to the bottom of the mounting frame is provided at the bottom of the liquid storage tank body;

[0011] Furthermore, reinforcement rods are fixedly connected to the inner top wall and the inner bottom wall of the installation frame, and a ladder is fixedly connected to one side of the installation frame.

[0012] Furthermore, a lifting ring is fixedly connected to one side of the installation frame, and the number of the lifting rings is two, and the two lifting rings are symmetrically distributed on the left and right sides of the installation frame.

[0013] Furthermore, a mounting sleeve is fixedly connected to one side of the mounting frame, a hydraulic cylinder is fixedly installed on the inner top wall of the mounting sleeve, and a moving wheel extending to the bottom of the mounting sleeve is fixedly connected to the output end of the hydraulic cylinder.

[0015] Compared with the prior art, the utility model provides an iron-based etching liquid storage tank that is easy to transport and has the following beneficial effects:

[0016] 1. The iron-based etching liquid storage tank which is easy to transport is provided with a filter box and a filter plate, and then a connecting pipe is provided, so that the etching liquid inside the liquid storage tank body can enter the filter box through the connecting pipe, so as to filter it. Since the filter box and the filter plate are both located outside the liquid storage tank body, it is convenient for the staff to remove the filter plate and clean it, so as to avoid clogging of the filter plate due to long-term filtration, thereby affecting the filtering effect, and achieving the effect of facilitating the cleaning of filtered impurities.

[0017] 2. The iron etching liquid storage tank which is easy to transport is provided with a hydraulic cylinder to drive the moving wheel to move downward.

[0028] In this embodiment, the top of the liquid storage tank body 2 is fixedly connected with a liquid inlet pipe 10 connected thereto, and the end of the liquid inlet pipe 10 away from the liquid storage tank body 2 is sleeved with a sealing cover plate 11, and an elastic connecting rope 12 is fixedly connected between the sealing cover plate 11 and the liquid storage tank body 2. By setting the sealing cover plate 11, the interior of the liquid storage tank body 2 can be sealed.

[0034] By adopting the above technical solution, a hydraulic cylinder 17 is set to drive the moving wheel 18 to move downward. At this time, the moving wheel 18 is in contact with the ground. At the same time, the hydraulic cylinder 17 lifts the installation frame 1, which makes it convenient for the staff to move the liquid storage tank body 2. Conversely, the support seat 19 is in contact with the ground, thereby being able to support the liquid storage tank body 2, making it convenient for the staff to transport it.

[0035] The working principle of the above embodiment is:

[0036] First, remove the sealing cover 11 and deliver the etching liquid to the inside of the liquid storage tank body 2 through the liquid inlet pipe 10. After the delivery is completed, cover the sealing cover 11. Then start the hydraulic cylinder 17 to drive the moving wheel 18 to move downward, so that the hydraulic cylinder 17 can lift the liquid storage tank body 2 slightly. The staff uses the transportation tool to push the entire device to move. After moving to the appropriate position, the staff uses the sling to lift the installation frame 1 through the lifting ring 15 and place it at the designated position. At the same time, start the hydraulic cylinder 17 to drive the moving wheel 18 to move upward. At this time, the installation frame 1 is stabilized on the platform due to the action of the support seat 19.
