Description

Technical Field

[0001] This utility model relates to the technical field of sedimentation tanks, specifically a waste acid sedimentation tank. Background Technology

[0002] In the metal finishing industry, strong inorganic acids are commonly used to remove surface oxides to reduce their impact on subsequent production operations. However, as the metal concentration increases, the oxide removal rate usually decreases. When the oxide scale is no longer sufficiently removed, the acid solution must be discarded, becoming waste acid.

[0003] According to Chinese Patent No. CN215137171U, a liquid-solid separation sedimentation tank for a solution filter includes a box-type tank body and a cover plate. The cover plate is provided with reinforcing ribs on its surface and handles on both sides. The cover plate is provided with a curved vent port that connects to the box-type tank body. The box-type tank body is provided with an inlet at the top, a drain outlet in the middle, and a slag discharge outlet at the bottom. The inlet and drain outlet are respectively located on opposite sides of the box-type tank body. The pipe ports of the slag discharge outlet, inlet, and drain outlet are all flange ports for easy connection to external management.

[0004] In the above solution, a cover is installed on top of the box-type tank for sealing, which still has the following disadvantages: when new waste acid is poured into the box-type tank, the cover needs to be removed from the box-type tank and placed on the ground or against the tank wall, which increases the probability of the waste acid being contaminated during sedimentation. Utility Model Content

[0005] The purpose of this invention is to provide a waste acid settling tank to solve the problem that when new waste acid is poured into the box-type tank, the top cover needs to be removed from the box-type tank and placed on the ground or against the tank wall, which increases the probability of the waste acid being contaminated during settling.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a waste acid sedimentation tank, including a sliding plate, the sliding plate being slidably disposed above the sedimentation tank body, two sliding grooves being formed on the top surface of the sedimentation tank body, a sliding rod being fixed inside the sliding groove, a movable plate being slidably inserted on the sliding rod, the top surface of the movable plate being fixed to the bottom surface of the sliding plate, a cover plate being rotatably disposed on one side of the sliding plate, a connecting groove being formed on the side of the cover plate near the sliding plate, a connecting strip being fixed on the side of the sliding plate near the cover plate, and the connecting groove and the connecting strip being hinged to each other.

[0007] Preferably, the top surface of the cover plate has an observation opening, and a transparent plate is fixed inside the observation opening.

[0008] Preferably, the top surface of the cover plate has two adding holes, the top surface of the cover plate has two rotatably disposed closed discs, the top surface of the cover plate has two rotating columns fixed, and a connecting plate is rotatably inserted into the rotating columns, with one side of the connecting plate fixed to the surface of the closed disc.

[0009] Preferably, the top surface of the cover plate is fixed with two limiting arc plates, and the top surface of the closed disc is fixed with a handle.

[0010] Preferably, support columns are fixed at the four corners of the bottom surface of the sedimentation tank body, and anti-slip pads are fixed at the bottom of the support columns.

[0011] Preferably, the top surface of the sedimentation tank body is provided with a through groove, and a siphon tube is slidably inserted into the inside of the through groove.

[0012] Compared with existing technologies, a waste acid settling tank using the above-mentioned technical solution has the following beneficial effects:

[0013] First, the staff will push the sliding plate to slide the cover plate on the top surface of the sedimentation tank. Then, the staff will pour the waste acid into the sedimentation tank and let it stand. Afterward, the staff will apply force to the sliding plate again, so that the sliding plate and the cover plate can be placed on top of the sedimentation tank again to prevent impurities in the external environment from entering the sedimentation tank and interfering with the sedimentation of the waste liquid. After the sliding plate moves to one side of the top surface of the sedimentation tank, the cover plate will rotate around the connecting strip as the center, and finally make the cover plate perpendicular to one side of the sedimentation tank. This prevents the cover plate from being held up for a long time and avoids the cover plate from being contaminated due to direct contact with the ground, thus reducing the probability of the waste acid being contaminated during sedimentation.

[0014] 2. When the waste acid inside the settling tank is settling, the staff can observe the settling process through the transparent plate. At the same time, the staff can add the settling chemicals into the settling tank through the adding hole according to the settling state of the waste acid. When the cover plate is perpendicular to one side of the settling tank, the sealing plate will be blocked by the limiting arc plate to prevent the sealing plate from changing due to the change of the position of the cover plate, which increases the convenience of the staff to operate in the waste acid settling tank.

[0015] Third, after the waste acid inside the sedimentation tank has settled, the staff will adjust the position of the siphon pipe and use the siphon pipe and the siphon principle to extract the settled waste acid from the sedimentation tank. The sedimentation tank will be supported upward by the support column, which will keep the sedimentation tank away from the ground, prevent water from the ground from contacting the surface of the sedimentation tank and causing corrosion, and extend the service life of the sedimentation tank.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, a waste acid settling tank includes a sliding plate 1, which is slidably disposed above the settling tank body 2. Two sliding grooves 4 are opened on the top surface of the settling tank body 2. A sliding rod 5 is fixed inside the sliding groove 4. A movable plate 6 is slidably inserted on the sliding rod 5. The top surface of the movable plate 6 is fixed to the bottom surface of the sliding plate 1. A cover plate 3 is rotatably disposed on one side of the sliding plate 1. A connecting groove 7 is opened on the side of the cover plate 3 near the sliding plate 1. A connecting strip 8 is fixed on the side of the sliding plate 1 near the cover plate 3. The connecting groove 7 and the connecting strip 8 are hinged to each other.

[0023] In use, the staff first pushes the sliding plate 1 to slide the cover plate 3 on the top surface of the sedimentation tank body 2. Then, the staff pours the waste acid into the sedimentation tank body 2 and lets it stand. Afterward, the staff applies force to the sliding plate 1 again, so that the sliding plate 1 and the cover plate 3 can cover the sedimentation tank body 2 again, preventing impurities in the external environment from entering the sedimentation tank body 2 and interfering with the sedimentation of the waste liquid. After the sliding plate 1 moves to one side of the top surface of the sedimentation tank body 2, the cover plate 3 will rotate around the connecting strip 8 as the center, and finally make the cover plate 3 perpendicular to one side of the sedimentation tank body 2. This prevents the cover plate 3 from being held up for a long time and avoids the cover plate 3 from being contaminated due to direct contact with the ground, thus reducing the probability of the waste acid being contaminated during sedimentation.

[0024] like Figure 4As shown, the top surface of the cover plate 3 has an observation port 9, and a transparent plate 10 is fixed inside the observation port 9. The top surface of the cover plate 3 has two adding holes 11. The top surface of the cover plate 3 has two rotatably mounted sealing discs 12. The top surface of the cover plate 3 has two rotating columns 13, and a connecting plate 14 is rotatably inserted into the rotating columns 13. One side of the connecting plate 14 is fixed to the surface of the sealing disc 12. The top surface of the cover plate 3 has two limiting arc plates 16, and the top surface of the sealing disc 12 has a handle 15.

[0025] During use, when the waste acid inside the sedimentation tank body 2 is settling, the staff can observe the settling process of the waste acid inside the sedimentation tank body 2 through the transparent plate 10. At the same time, the staff can add the settling chemicals into the sedimentation tank body 2 through the adding hole 11 according to the settling state of the waste acid. When the cover plate 3 is vertical to one side of the sedimentation tank body 2, the sealing plate 12 will be blocked by the limiting arc plate 16 to prevent the sealing plate 12 from changing due to the change of the position of the cover plate 3, which increases the convenience of operation for the staff in the waste acid sedimentation tank.

[0026] like Figure 2 As shown, support columns 17 are fixed at the four corners of the bottom surface of the sedimentation tank body 2, and anti-slip pads 18 are fixed at the bottom of the support columns 17. A through groove 19 is opened on the top surface of the sedimentation tank body 2, and a siphon tube 20 is slidably inserted inside the through groove 19.

[0027] During use, after the waste acid inside the sedimentation tank body 2 has settled, the staff will adjust the position of the siphon pipe 20 and use the siphon pipe 20 and the siphon principle to extract the settled waste acid from the sedimentation tank body 2. The sedimentation tank body 2 will be supported upward by the support column 17, which will keep the sedimentation tank body 2 away from the ground, prevent the water on the ground from contacting the surface of the sedimentation tank body 2 and causing corrosion, and extend the service life of the sedimentation tank body 2.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
