[0016] 1. The present invention is used to separate water produced by the reaction of leather retanning agent from raw materials, and to extract excess solvent from the reaction by vacuum, so as to achieve drying treatment of leather retanning agent;

[0017] a. Separate the water produced by the reaction from the raw materials. The byproduct produced during the reaction is small molecules of water, which will be evaporated along with the solvent and enter the water separator. The stratification is achieved by taking advantage of the fact that the solvent and water are immiscible and the density of water is generally greater than that of the solvent. Then the water is released from the drain port at the bottom, and the solvent at the top flows back into the reactor to continue the reaction.

[0018] b. Use vacuum to extract excess solvent from the reaction.

[0019] c. The design innovation of this product lies in its multifunctionality, which enables one device to complete two functions. The glass tube next to it can also help observe the amount of water or solvent inside.

[0020] 2. The present invention drives the stirring column to stir the layers of the oil layer and the water layer by means of a movable plate that reciprocates and rotates up and down, thereby avoiding uneven stratification due to adsorption on the inner wall of the observation tube, which makes accurate observation inconvenient.

[0037] See also Figure 7-9 The rotating assembly 10 shown in the figure includes a movable plate 11 which is arranged obliquely and moves in the observation tube 3. A plurality of connecting holes 12 are circumferentially distributed and penetrate the movable plate 11. A stirring column 13 which moves on the inner wall of the observation tube 3 is fixedly connected to the edge of the movable plate 11. A movable rod 14 is fixedly connected to the central axis of the movable plate 11. A movable assembly 15 is provided below the movable plate 11 to drive the movable plate 11 to rotate and reciprocate up and down.

[0038] See also Figure 4 , 9 The power assembly 19 shown in the figure includes a servo motor 20 located outside the observation tube 3, the output shaft of the servo motor 20 is fixedly connected to a sleeve rod 21, the outer surface of the sleeve rod 21 is sleeved with a sleeve 22 that penetrates into the observation tube 3, the top of the sleeve 22 is fixedly connected to a first bevel gear 23, the first bevel gear 23 is meshed with a second bevel gear 24, the middle axis of the second bevel gear 24 is fixedly connected to a connecting rod 25 that is fixedly connected to the middle axis of the rotating card wheel 16, the cross-section of the sleeve rod 21 is cam-shaped, the cross-section shape of the sleeve 22 is adapted to the cross-section shape of the sleeve rod 21, and the sleeve 22 is also provided with a limit assembly 26 for ensuring the position of the rotating card wheel 16.

[0039] See also Figure 7-9 The limiting assembly 26 shown in the figure includes a fixed sleeve 27, which is sleeved with the sleeve 22 and the movable rod 14 at the same time. A fixed sleeve 28 sleeved with the connecting rod 25 is fixedly connected to the fixed sleeve 27.

[0040] Among them, a rubber compression airbag 37 is connected and fixed on the observation tube 3. By pressing, it helps to move the liquid in the observation tube 3 and cooperate with the movable plate 11 to facilitate leveling.

[0041] A heating device is provided on the inner wall of the reaction kettle 1, which may be a heating jacket or a steam heating layer structure.

[0042] In this embodiment, by using the condenser tube in conjunction with the connecting tube and the first connecting tube 7 and the second connecting tube 8, the dehydration and desolvation of the device can be combined into one, so that one set of devices can complete two functions, thereby improving efficiency. The amount of water or solvent inside can be observed through the observation tube 3. Since the oil layer and the water layer in the observation tube 3 are at the stratification point, the inner wall contact point is prone to uneven stratification (caused by adsorption), resulting in unclear stratification lines and low reading accuracy. By adjusting the component 29, the movable plate 11 is located at the stratification point, and the servo motor 20 drives the sleeve rod 21 and the sleeve 22 to rotate. Since the stirring rod is always attached to the inner wall of the observation tube 3, To prevent the movable plate 11 from tipping over, the movable rod 14 is always located at the central axis position of the observation tube 3, and under the action of the fixed sleeve 27 and the fixed ring 28, the first bevel gear 23 drives the second bevel gear 24, and the connecting rod 25 rotates in its original position, thereby rotating the movable component 15, driving the movable plate 11 to rise and fall while rotating, and the stirring rod stirs the inner wall of the observation tube 3 to eliminate the uneven and unclear stratification line caused by adsorption of the inner wall of the observation tube 3 at the stratification position (at the same time, the height of the position gap of the stratification line at one end will change), so as to facilitate precise quantification (the outer surface of the observation tube 3 is engraved with scales).

[0043] It is worth noting that the movable plate 11 is made of a high-density material, which ensures that the movable plate 11 cooperates with the rotating clamping wheel 16 to make a reciprocating up and down movement.

[0044] Among them, the connecting pipe is connected to the atmosphere or connected to a vacuum pump, which can be used to remove the reactant. Example
