Description

Technical Field

[0001] This utility model belongs to the field of cobalt sulfate production technology, and more specifically, it relates to a cobalt sulfate crystallization apparatus. Background Technology

[0002] Cobalt sulfate is an inorganic compound composed of cobalt, sulfur, and oxygen. It is one of the most important salts of cobalt metal and is mainly used in the manufacture of cathode materials for lithium-ion batteries, ceramic glazes, and paint driers. Currently, cobalt sulfate is produced through a reaction with other solutions, with common methods including evaporation crystallization and cooling crystallization.

[0003] During the production of cobalt sulfate, crystals accumulate on the inner wall of the crystallization vessel, forming a hard scale layer. This leads to a sharp decrease in heat exchange efficiency and a reduction in effective volume, resulting in frequent shutdowns for cleaning and severely impacting the continuity and efficiency of production.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cobalt sulfate crystallization device in order to achieve a more practical purpose. Utility Model Content

The heating tank is provided with a liquid outlet pipe, the cover body is provided with a liquid inlet pipe that communicates with the inside of the heating tank, and the cover body is provided with a cleaning mechanism. The cleaning mechanism includes a cleaning component disposed inside the heating tank for cleaning crystals on the inner wall of the tank, a transmission component disposed inside the heating tank for driving the cleaning component to reciprocate in the vertical direction, and a drive component disposed on the cover body for providing power to the transmission component.

[0007] The technical principle of this utility model is as follows: the driving component provides power to the transmission component, and the transmission component drives the cleaning component to reciprocate in the vertical direction, thereby cleaning the crystals deposited on the inner wall of the heating tank and improving the cleaning effect.

The transmission assembly includes a housing fixedly mounted on the cover and located inside the heating tank, and a guide part located inside the housing. The vertical shaft is located on the guide part, and the guide part is used to drive the cleaning component to reciprocate in the vertical direction.

[0012] Furthermore, the guide section includes a guide shaft, a guide sleeve, a connecting shaft, and a limiting block. The guide shaft is coaxially fixedly mounted on the power output shaft of the drive component. A wavy guide groove is formed on the guide shaft.

[0029] like Figures 1 to 7 As shown, a cobalt sulfate crystallization apparatus includes a heating tank 1 and a cover 2 that cooperates with the heating tank 1. The heating tank 1 is provided with a liquid outlet pipe 3, and the cover 2 is provided with a liquid inlet pipe 4 that communicates with the interior of the heating tank 1. The cover 2 is provided with a cleaning mechanism, which includes a cleaning component 6 disposed inside the heating tank 1 for cleaning crystals on the inner wall of the tank, a transmission component 7 disposed inside the heating tank 1 for driving the cleaning component 6 to reciprocate in the vertical direction, and a drive component 8 disposed on the cover 2 for providing power to the transmission component 7.

[0030] Cobalt sulfate solution is injected into heating tank 1 through inlet pipe 4. At this time, outlet pipe 3 is closed. Heating tank 1 heats the cobalt sulfate solution, evaporating some water and concentrating the solution to form supersaturation, precipitating cobalt sulfate crystals. Simultaneously, drive component 8 provides power to transmission component 7, which drives cleaning component 6 to reciprocate vertically, cleaning the crystals deposited on the inner wall of heating tank 1. Heating is turned off after completion. For very hard scale layers, no high pressure is required, reducing the risk of wear or damage to the inner wall of heating tank 1. The vertically reciprocating cleaning component 6 uses vertical force to act on the scale layer. This method is usually more effective for scraping hard, dense scale, and gravity will naturally carry away the scraped crystal fragments, providing good self-cleaning and chip removal effects.

[0031] The bottom of the heating tank 1 has an opening, and a filter plate 5 is installed at the opening. The liquid outlet pipe 3 is located at the opening. After heating is completed, the liquid outlet pipe 3 is opened to separate the mother liquor from the cobalt sulfate crystals.

[0032] Furthermore, such as Figures 2-3As shown, the cleaning assembly 6 includes a vertical shaft 601 mounted on the transmission assembly 7 and arranged vertically, a connecting rod 602 fixedly mounted on the vertical shaft 601 and arranged horizontally, and a cleaning component 603 fixedly mounted on the connecting rod 602 and abutting against the inner wall of the heating tank 1.

[0033] Except for the vertical axis 601, the cleaning components 6 consist of multiple sets, with two sets in this case, and are evenly distributed on the vertical axis 601. This arrangement can increase the coverage area of ​​the cleaning components 6, thereby improving the cleaning efficiency and effect on the inner wall of the heating tank 1.

[0034] Furthermore, such as Figure 6 As shown, the vertical cross-section of the cleaning component 603 is circular.

[0035] The outer diameter of the cleaning component 603 is equal to the inner diameter of the heating tank 1. The cleaning component 603 is in close contact with the inner wall of the heating tank 1. The cleaning component 603 and the inner wall of the heating tank 1 are in line contact, with a small contact area, which can further reduce the risk of wear or damage to the inner wall of the heating tank 1.

[0036] Furthermore, such as Figure 7 As shown, the vertical cross-section of the cleaning component 603 is rectangular.

[0037] The cleaning component 603 here is a ring. Both sides of the rectangular cross-section cleaning component 603 are in close contact with the inner wall of the heating tank 1. The above configuration makes the cleaning component 603 more effective at scraping away hard and dense scabs.

[0038] Furthermore, such as Figure 2 and Figure 3 As shown, the drive component 8 is fixedly installed on the cover 2. The power output shaft of the drive component 8 passes through the cover 2 and is located inside the heating tank 1. The transmission component 7 includes a housing 701 fixedly installed on the cover 2 and located inside the heating tank 1, and a guide portion located inside the housing 701. The vertical shaft 601 is located on the guide portion, and the guide portion is used to drive the cleaning component 6 to reciprocate in the vertical direction.

[0039] Furthermore, such as Figure 4 and Figure 5As shown, the guide section includes a guide shaft 702, a guide sleeve 703, a connecting shaft 704, and a limiting block 705. The guide shaft 702 is coaxially fixedly mounted on the power output shaft of the drive component 8. A wavy guide groove 7021 is opened on the guide shaft 702. The guide sleeve 703 is coaxially sleeved on the guide shaft 702. A guide component 706 is provided on the guide sleeve 703 and slidably disposed in the guide groove 7021. The connecting shaft 704 is coaxially fixedly mounted on the guide sleeve 703. A limiting groove 7041 is opened on the side wall of the connecting shaft 704. An opening is opened at the end of the housing 701 away from the drive component 8. The limiting block 705 is fixedly installed in the opening. The connecting shaft 704 slides through the limiting block 705. A limiting component 707 is provided on the limiting block 705 and slidably disposed in the limiting groove 7041. The cleaning component 6 is disposed on the connecting shaft 704.

[0040] A wavy guide groove 7021 is arranged around the guide shaft 702. The distance between the lowest and highest points of the wavy groove is the distance of the cleaning component 6's reciprocating motion in the vertical direction. The guide sleeve 703 consists of two identical arc-shaped plates 7031 and a base 7032. The two arc-shaped plates 7031 are symmetrically arranged on the base 7032, and the diameter of the circle formed by the two arc-shaped plates 7031 is equal to the outer diameter of the guide shaft 702. That is, the guide sleeve 703 is fitted onto the guide shaft 702, and the guide sleeve 703 is in close contact with the guide shaft 702. The arc-shaped plate 7031 has a mounting hole, and the guide member 706 is arranged in the mounting hole and slidably arranged in the guide groove 7021. The upper end of the connecting shaft 704 is fixedly installed at the lower end of the base 7032, and the vertical shaft 601 is fixedly installed at the lower end of the connecting shaft 704. Under the action of the limiting groove 7041 of the connecting shaft 704 and the upper limit member 707 of the limiting block 705, when the guide shaft 702 rotates horizontally, the connecting shaft 704 moves up and down within the limiting block 705, i.e., reciprocates in the vertical direction, thereby driving the vertical shaft 601 to reciprocate in the vertical direction. With the guide groove 7021 having a fixed waveform, the rotational speed of the guide shaft 702 is proportional to the frequency of the vertical shaft 601's reciprocating motion in the vertical direction. By controlling the rotational speed of the guide shaft 702 through the driving member 8, the frequency of the vertical shaft 601's reciprocating motion in the vertical direction can be controlled.
