Description

Technical Field

[0001] The utility model relates to the technical field of flake graphite processing equipment, in particular to a flake graphite pickling tank. Background Art

[0002] During the processing of expandable graphite, the flake graphite used as the raw material requires pickling. In existing technology, the raw material (flake graphite) is typically placed in a pickling tank, where acid is then introduced for soaking and rinsing. Wastewater generated during this process is continuously discharged and then filtered and processed before being returned for recycling. During the pickling process, the acid is typically introduced into the tank via an inlet pipe, typically located at a higher position, and then discharged through a drain pipe at the bottom. During this process, the acid soaks and rinses the material. However, the acid flow efficiency depends on the inlet flow rate, which is typically low. Furthermore, increasing the flow rate could cause the acid to overflow the tank, resulting in a relatively low overall pickling efficiency. Utility Model Content

[0024] In an exemplary embodiment, Figure 1 、 2 As shown, this embodiment provides a flake graphite pickling tank, which includes: a pickling tank body 1, a plurality of liquid inlet pipes 2 arranged side by side in a transverse manner are installed at the bottom of the pickling tank body 1, and both ends of the liquid inlet pipes 2 are fixedly extended to the outside of the pickling tank body 1, both of which can be used as inlet ends for acid to enter, and are respectively installed with valves for controlling the opening and closing states, a plurality of nozzles 3 are respectively installed on each liquid inlet pipe 2, and the nozzles 3 on each liquid inlet pipe 2 are distributed along the axial direction and the outlet is arranged upward, and an overflow port 4 is also provided on the upper end side wall of the pickling tank body 1, the acid is introduced through the liquid inlet pipe 2, sprayed upward through the nozzle 3, and then the acid gradually rises and finally is discharged in an overflow manner through the overflow port 4 arranged at a higher position, so that the flow rate of the acid can be appropriately improved; a valve for loading the original A loading tank 5 for raw materials (i.e., flake graphite) is provided. The loading tank 5 includes a frame 6 and a partition 7 separating the bottom of the frame 6. A plurality of through holes are provided on the frame 6 and the partition 7. The raw materials are loaded into the frame 6 of the loading tank 5, and the bottom is supported by the partition 7. The through holes on the periphery, i.e., the bottom, allow the acid to pass through normally, so that pickling can be smoothly achieved. Support plates 8 are fixedly connected to both ends of the bottom of the frame 6, and notches 9 are provided on the support plates 8 for accommodating each liquid inlet pipe 2 so that the support plates 8 can be against the inner bottom surface of the pickling tank body 1. The notch 9 is an inverted U-shaped structure, so that the loading tank 5 can be smoothly placed in the pickling tank body 1 without contacting or colliding with the provided liquid inlet pipe 2 and the nozzle 3 (the nozzle 3 is located below the partition 7 and is separated by a distance).

[0025] In the above embodiment, more liquid inlet pipes 2 are provided at the bottom of the pickling tank body 1, and more acid liquid is introduced into the pickling tank body 1 through the nozzles 3, and then the raw materials in the loading tank 5 are washed upward (the raw materials are also soaked), and are discharged through the overflow port 4 provided at a higher position. The overflow port 4 provided can be of a larger size (wider, higher), so that the acid liquid introduced through multiple liquid inlet pipes 2 can be discharged smoothly, so that the flow rate of the acid liquid can be increased, thereby improving the pickling efficiency accordingly, solving the problem of the pickling efficiency being maintained at a low level in the prior art; in more detail, all the nozzles 3 provided can be located directly below the enclosure 6; further, during operation, pickling may cause some impurities to fall, and heavier ones may settle downward, so a nozzle 3 connected to it is also provided at the bottom of the pickling tank body 1.

Similar to the prior art, this part of the acid liquid can be filtered and processed, and then returned for reuse; furthermore, support legs 15 are fixedly connected at the four corners of the bottom of the pickling tank body 1, so that the bottom is raised and a height space is left for the smooth arrangement of structures such as the slag discharge bucket 10 and the slag discharge pipe 11.

[0028] like Figure 1-3As shown, the loading tank 5 is supported in the pickling tank body 1 by the support plate 8 at the bottom. In order to further improve its stability in the pickling tank body 1, support bars 16 are fixedly connected to the two end walls facing each other in the pickling tank body 1. The loading tank 5 is fixedly connected with ears 17 that can overlap with the two support bars 16. The two ears 17 are fixedly connected with lifting ears 18 extending to the top of the pickling tank body 1. At the same time, the loading tank 5 can be lifted out by lifting through the lifting ears 18 to facilitate the placement of raw materials. In and out, in more detail, the overflow port 4 is located above the support bar 16, and the upper edge of the overflow port 4 can also be located above all the through holes; in further detail, the ear 17 includes a horizontal plate and a vertical plate fixedly connected thereto, the horizontal plate is fixedly connected to the outer wall of the upper end of the loading slot 5, the vertical plate is against the support bar 16, all the through holes are located below the horizontal plate, the horizontal plate and the vertical plate are enclosed to form a "7", and the vertical plate is against the corresponding support bar 16, and cooperates with the support plate 8 at the bottom to stabilize the loading slot 5.
