Description

Technical Field

[0002] A scraper evaporator is a device commonly used for the evaporation and concentration of high-viscosity liquids and the evaporation of heat-sensitive substances. It can effectively process the solvent in the liquid in a short time and is widely used in industries such as chemical engineering, food, and pharmaceuticals, especially suitable for processes that are prone to crystallization or contain high-viscosity materials.

[0003] Currently, the following areas in the existing technology still need to be improved: Different stock solution substances require different pressures when forming a liquid film for evaporation and drying. The existing scraper evaporator cannot flexibly adjust the contact pressure between the scraper and the stock solution substance and the inner wall of the scraper evaporator according to the working conditions, resulting in low drying efficiency for some stock solutions. After long-term use, the surfaces of the scraper and the evaporator are prone to wear, damage, or deformation due to the large contact pressure, thereby reducing the efficiency and service life of the equipment. During the evaporation process of high-viscosity stock solution, there may be residual substances in the evaporator. It is relatively difficult to clean the inside of the existing scraper evaporator, increasing the downtime and maintenance costs. Summary of the Invention

[0017] A usage method of a copper acid waste liquid concentration and drying device includes the following usage method:

[0018] S1: Before using the device, first control the second motor to start through the controller. The belt pulley rotates to drive the conveyor belt to move. The movement of the conveyor belt drives the second sleeve and the third sleeve to move simultaneously towards the direction close to the barrel wall of the scraper evaporator main body. The movement of the third sleeve drives the transition block, the pressure sensor and the first connecting block to move. The movement of the transition block drives the first corrugated sleeve to expand and contract. The movement of the first connecting block drives the scraper to move. The auxiliary rod expands and contracts synchronously with the scraper. After the scraper touches the barrel wall of the scraper evaporator main body, the pressure sensor detects the pressure and transmits the pressure value to the controller, and the controller controls the second motor to stop running;

[0019] S2: The controller then controls the second motor to rotate back. After the distance between the scraper and the barrel wall of the scraper evaporator main body reaches the set distance, the second motor stops running;

[0020] S3: The controller controls the first motor to start. The first rotating shaft rotates to drive the material distribution plate, the telescopic assembly, the auxiliary rod and the scraper to rotate. The original liquid to be dried is conveyed into the scraper evaporator main body through the feeding pipe. The material distribution plate evenly distributes the original liquid to the barrel wall of the scraper evaporator main body. The scraper rotates continuously to form a thin film-like liquid layer of the original liquid. The liquid film continuously moves downward and is heated and evaporated and concentrated to form dry materials. The steam generated during the heating process is discharged through the exhaust pipe;

[0021] When the inside of the scraper evaporator main body needs to be cleaned:

[0022] S4: Transport water into the water inlet tank of the sealing sleeve through a water pipe. The water flows into the first rotating shaft through the water inlet tank and the water inlet holes, and is sprayed onto the inner wall of the scraper evaporator body through the nozzles on the first rotating shaft. At the same time, start the first motor. The rotation of the first rotating shaft drives the scraper to rotate, and at the same time, clean the inner wall of the scraper evaporator body and the scraper.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) By setting the telescopic assembly, the technical effect that can be achieved is to facilitate adjusting the overall length of the telescopic assembly according to the properties of different stock solution substances to adjust the contact pressure between the scraper and the stock solution, improve the drying efficiency of the stock solution, avoid unnecessary friction and wear between the scraper and the inner wall of the scraper evaporator body, extend the service life of the equipment, and the setting of the pressure sensor enables the telescopic assembly to achieve a self-compensation function, adjusting the telescopic length of the telescopic assembly during operation according to the change of the pressure value, facilitating dealing with the wear of the inner wall of the scraper evaporator body and the scraper after long-term use, and ensuring the drying efficiency of the stock solution.

[0025] (2) By setting the telescopic assembly, another technical effect that can be achieved is that the first corrugated sleeve is fixedly connected between the first sleeve and the transition block, facilitating telescoping in cooperation with the movement of the transition block. The first sleeve and the first corrugated sleeve are sleeved outside the second sleeve and the third sleeve, facilitating the movement of the second sleeve and the third sleeve along the first sleeve. The second sleeve is sleeved outside the third sleeve, facilitating the movement of the third sleeve along the second sleeve. The setting of the first corrugated sleeve can prevent the stock solution from sticking to the second sleeve and the third sleeve during drying, affecting the normal operation of the telescopic assembly. There is a first rivet fixedly connected between the conveyor belt and the first sleeve, and the first rivet plays a limiting role, facilitating the pulley, the conveyor belt, and the first rivet to cooperate to drive the third connecting block and the second sleeve to perform telescopic movement. One end of the two fourth connecting blocks is provided with a fixing block, facilitating the limitation of the moving distance of the fourth connecting block and the third sleeve. There is a second rivet fixedly connected between the fixing block and the conveyor belt, and the second rivet plays a limiting role, facilitating the pulley, the conveyor belt, and the second rivet to cooperate to drive the fourth connecting block and the third sleeve to perform telescopic movement.

[0026] (3) By setting the auxiliary rod, the first rotating shaft and the material distribution plate, the technical effects that can be achieved are as follows: there is a telescopic rod inside the fixed rod and the second corrugated sleeve. The diameter of the auxiliary rod is smaller than that of the telescopic assembly, which facilitates the telescopic movement of the auxiliary rod in cooperation with the telescopic movement of the telescopic assembly. It is convenient for the telescopic assembly to drive the scraper and the auxiliary rod to telescopically move to adjust the contact pressure between the scraper and the stock solution, improving the drying efficiency of the stock solution. The apertures of multiple water outlet holes gradually increase from the end close to the material distribution plate to the end far from the material distribution plate, which is convenient for evenly delivering water to the inside of the scraper evaporator main body. A spray head is provided on each water outlet hole, and the diameter of each spray head matches the aperture of each water outlet. The spray head is convenient for cleaning the inside of the scraper evaporator main body and the scraper itself in cooperation with the first rotating shaft and the scraper, reducing the maintenance time and maintenance cost. The material distribution plate is arranged in a flat-top conical shape, which is convenient for evenly distributing the stock solution onto the inner wall of the scraper evaporator main body, facilitating subsequent heating and drying of the stock solution.
