Description

Technical Field

[0001] The utility model belongs to the technical field of sedimentation tanks, and in particular relates to a structure of a sedimentation tank for pickling waste liquid. Background Art

[0002] The pickling waste liquid generated during the pickling treatment of metal surfaces usually contains acidic solutions, metal ions, organic matter and other impurities. Because it contains acidic components and other harmful substances, the pickling waste liquid needs to be recycled and treated in an environmentally friendly manner to avoid harm to the environment and human health. When the pickling waste liquid is recycled by the sedimentation method, a large amount of sludge will be generated. These sludges will accumulate on the inclined plates in the sedimentation tank, which will interfere with the normal sedimentation process and affect the water quality of the sedimentation tank. Therefore, generally after the inclined plate sedimentation tank has been running for 1-3 months, the flocs or sediment particles accumulated on the inclined plates in the sedimentation tank body need to be cleaned. The general cleaning method is to lower the water level in the sedimentation tank body to below the inclined plate, and then use a high-pressure water gun to clean it manually. However, since the inclined plates are all inclined, when using a high-pressure water gun for cleaning, as long as the upper part of the inclined plate can be impacted by the water flow, it will affect the cleaning effect, so it takes a long time to clean, and after cleaning, some impurities will still accumulate on the lower surface of the inclined plate, making it easier to accumulate on the surface of the inclined plate, thereby shortening the cleaning cycle and increasing the workload of the cleaning personnel. Utility Model Content

[0003] In view of the above problems, the utility model discloses a pickling waste liquid sedimentation tank structure, which solves the problem that the cleaning effect of the inclined plate in the inclined plate sedimentation tank in the prior art is poor and frequent cleaning is required.

[0004] The specific technical solutions are as follows:

[0005] A pickling waste liquid sedimentation tank structure, comprising a tank body, an inclined plate group arranged inside the tank body, and an adjusting device for driving the inclined plate group to move. The inclined plate group is composed of a plurality of horizontally arranged inclined plates, and adjacent inclined plates are attached to each other. On both sides of each inclined plate, folding plate parts are arranged along the length direction of the tank body, and rotating shafts for movably connecting with the adjusting device are horizontally arranged at the upper and lower ends of each folding plate part; The adjusting device includes a support plate, a fixed plate, a movable frame, and a driving component. The number of support plates is two and they are horizontally arranged in the tank body. The two support plates are distributed on both sides of the lower end of the inclined plate group, and a plurality of placing grooves for placing the lower rotating shafts of the inclined plates are horizontally arranged at the upper ends of the support plates, so that the support plates support the inclined plates through the rotating shafts; The fixed plates are arranged on the inner walls of both sides of the upper end of the tank body, and the movable frame is horizontally slidably arranged between the two fixed plates. The movable frame has a "C" - shaped structure, and a plurality of movable grooves for placing the upper rotating shafts of the inclined plates are horizontally arranged on both sides of the movable frame. The movable grooves are all waist - shaped structures and are longitudinally arranged. One end of the movable frame is driven by the driving component to move horizontally along the chute, so that the inclined plates are driven by the movable frame to move along their lower rotating shafts, realizing the adjustment of the inclined or vertical state of the inclined plates.

[0006] Furthermore, a plurality of sedimentation tanks are horizontally arranged at the bottom of the tank body. The two ends inside the tank body are separated by partition plates to form a water inlet chamber and a water outlet chamber. Water inlet pipes and water outlet pipes connected to the water inlet chamber and the water outlet chamber are respectively arranged at both ends of the tank body. A water outlet weir is arranged at the upper end inside the tank body, and one end of the water outlet weir is communicated with the water outlet chamber.

[0007] Furthermore, the driving component includes a lead screw, a threaded sleeve, and a driving motor. The two ends of the threaded sleeve are horizontally rotatably arranged in the water outlet chamber through bearings. One end of the threaded sleeve is closed and is driven to rotate by a driving motor installed on the outer wall of the tank body. The other end of the threaded sleeve horizontally penetrates through a partition plate on one side of the water outlet chamber, and the lead screw is horizontally threadedly connected in the threaded sleeve. One end of the lead screw is fixedly connected to one end of the movable frame, realizing that the driving motor drives the threaded sleeve to rotate and makes the lead screw move under the action of the thread, thereby driving the movable frame to move horizontally.

[0008] Furthermore, a plurality of horizontally arranged chutes are symmetrically arranged on the adjacent side walls of the two fixed plates, and a plurality of guide rods are horizontally arranged through between the two sides of the movable frame. The two ends of the guide rods are respectively slidably connected with the chutes on the fixed plates, realizing the horizontal sliding connection between the movable frame and the fixed plates.

[0009] Furthermore, the widths of the placing grooves and the movable grooves are adapted to the diameter size of the rotating shafts.

[0010] Furthermore, the cross - section of the inclined plate group has a honeycomb - like structure.

[0011] The beneficial effects of the present utility model are reflected in:

[0012] The inclination angle of the inclined plate group in the utility model can be controlled and adjusted by the adjusting device, so that when the inclined plates are cleaned regularly, the inclined plates can be kept in a vertical state to facilitate effective flushing by a high-pressure water gun, thereby ensuring the cleaning effect. At the same time, impurities after flushing can be directly precipitated downwards to avoid accumulation, thereby extending the cleaning cycle and reducing the labor burden.

A water inlet pipe 14 and a water outlet pipe 15 are respectively arranged at the two ends of the tank body 1 and are communicated with the water inlet chamber 12 and the water outlet chamber 13. An overflow weir 2 is arranged at the upper end inside the tank body 1, and one end of the overflow weir 2 is communicated with the water outlet chamber 13. The inclined plate group is located below the overflow weir 2. The inclined plate group is composed of a plurality of horizontally arranged inclined plates. Adjacent inclined plates 3 are attached to each other, so that the cross section of the inclined plate group is in a honeycomb structure. Folding plate parts 31 are bent along the length direction of the tank body 1 on both sides of each inclined plate 3. The length of the folding plate part 31 is the same as the length of the inclined plate 3. Rotating shafts 32 for movably connecting with the adjusting device are horizontally arranged at the upper and lower ends of each folding plate part 31.

[0023] The adjusting device includes a support plate 4, a fixing plate 5, a movable frame 6 and a driving component. The number of support plates 4 is two and they are horizontally arranged in the tank body 1. The two support plates 4 are distributed on both sides of the lower end of the inclined plate group. The two ends of the support plate 4 are fixedly connected to the two ends of the tank body 1. The bottom of the support plate 4 is supported by a support rod 42; a plurality of placing grooves 41 for placing the lower rotating shafts 32 of the inclined plates 3 are horizontally arranged at the upper end of the support plate 4. The width of the placing groove 41 is adapted to the diameter of the rotating shaft 32, so that the support plate 4 supports the inclined plate 3 through the rotating shaft 32. The fixing plate 5 is arranged on the inner walls of both sides at the upper end of the tank body 1. A plurality of horizontally arranged sliding grooves (not shown in the figure) are symmetrically arranged on the adjacent side walls of the two fixing plates 5. The movable frame 6 is in a "C" shape structure. A plurality of guide rods 62 are horizontally arranged through between the two sides of the movable frame 6. The two ends of the guide rod 62 are respectively slidably connected to the sliding grooves on the fixing plate 5, so that the movable frame 6 is horizontally slidably arranged between the two fixing plates 5 through the cooperation of the sliding grooves and the guide rods 62. A plurality of movable grooves 61 for placing the upper rotating shafts 32 of the inclined plates 3 are horizontally arranged on both sides of the movable frame 6. The movable grooves 61 are all in a waist shape structure and are arranged longitudinally. And the width of the movable groove 61 is adapted to the diameter of the rotating shaft 32. One end of the movable frame 6 moves horizontally along the sliding groove under the drive of the driving component, so that the inclined plate 3 moves along its lower rotating shaft 32 under the drive of the movable frame 6, realizing the adjustment of the inclined or vertical state of the inclined plate 3.

[0024] In this embodiment, the driving assembly includes a screw 7, a threaded sleeve 8, and a driving motor 9. Both ends of the threaded sleeve 8 are horizontally rotatably arranged in the water outlet bin 13 through bearings. One end of the threaded sleeve 8 is closed and driven to rotate by the driving motor 9 installed on the outer wall of the pool body 1. The other end of the threaded sleeve 8 horizontally penetrates the partition on one side of the water outlet bin 13, and the horizontal thread in the threaded sleeve 8 is connected to the screw 7, and one end of the screw 7 is fixedly connected to one end of the movable frame 6.

[0025] The threaded sleeve 8 is driven to rotate by the driving motor 9 and the screw rod 7 is moved under the action of the thread, thereby driving the movable frame 6 to move horizontally. During the horizontal movement of the movable frame 6, the movable groove 61 cooperates with the rotating shaft 32 at the upper end of the inclined plate 3, so that the inclined plate 3 rotates along its lower end rotating shaft 32 while its upper end rotating shaft 32 gradually rises in the movable groove 61. At this time, the inclined plates 3 in the inclined plate group rotate synchronously to one end until they are in a vertical state. During this process, the inclined plates 3 in the inclined plate group are attached to each other and move relatively until they are in a flush state. The top of the inclined plate group is in a flush state to facilitate flushing with a high-pressure water gun, thereby reducing flushing resistance and improving flushing effect.
