Description

Technical Field

[0001] This utility model belongs to the field of crystallization tank technology, and more specifically, it relates to a horizontal crystallization tank cleaning and disinfection device. Background Technology

[0002] Existing crystallization tanks are primarily cleaned using water and steam. The cleaning process involves first emptying the tank, then rinsing the inner walls, agitator shaft, thermometer sleeve, and other parts with water. After agitation for a certain time, the discharge valve is opened, and steam is introduced into the tank for a specific period. Finally, the microbial content is tested. As mentioned above, current cleaning methods primarily use water and steam. While these methods can remove residual material and sterilize the tank, the sterilization process is not thorough enough.

[0003] The automatic cleaning device for crystallization tanks uses water and steam for cleaning and disinfection, and is irradiated with ultraviolet light for half an hour before each use. First, it rinses with water to clean the pipes and remove any residual material inside the tank, then steam is introduced for disinfection. If the tank is not used for a long time and is to be reused, it should first be cleaned with water, then irradiated with ultraviolet light for half an hour. This ensures that all bacteria inside the tank are killed, guaranteeing product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontal crystallization tank cleaning and disinfection device to overcome the problem that the sterilization and disinfection of the crystallization tank is not thorough enough when cleaning and disinfecting it in the prior art.

[0005] This utility model is achieved by the following technical solution: a horizontal crystallization tank cleaning and disinfection device, including a tank body, an inlet installed on the top of the tank body, the inlet being connected to the outlet of a three-way valve, the two inlets of the three-way valve being connected to a feed pipe and a steam pipe respectively, and an ultraviolet germicidal lamp installed on the inner wall of the tank body.

[0006] Furthermore, a stirring shaft is rotatably installed inside the tank. Both ends of the stirring shaft are rotatably connected to the tank and extend out of the tank. One end of the stirring shaft is connected to a stirring motor, and the other end of the stirring shaft is connected to a water inlet pipe through a rotary joint. The stirring shaft is provided with a cleaning chamber that communicates with the water inlet pipe. Multiple nozzles are installed at intervals along the length of the stirring shaft, and the nozzles are connected to the cleaning chamber.

[0007] Furthermore, a cleaning water pipe is installed on the top of the inner wall of the tank, and multiple downward-facing nozzles are installed at intervals on the cleaning water pipe.

[0008] Furthermore, a jacket is provided on the outer side of the tank.

[0009] Furthermore, an ultraviolet germicidal lamp is installed on the top of the inner wall of the tank.

[0010] Furthermore, an ultraviolet germicidal lamp is installed at the bottom of the inner wall of the tank.

[0011] Furthermore, an eyepiece is also installed on the tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Compared with current crystallization tanks, this invention adds an ultraviolet germicidal lamp inside the tank, and also adds nozzles to the top of the stirring shaft and the inner wall of the tank, which can better clean and sterilize the crystallization tank, and the sterilization is more thorough.

[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0017] A horizontal crystallization tank cleaning and disinfection device includes a tank body 1. An inlet is installed at the top of the tank body 1, connected to the outlet of a three-way valve 2. The two inlets of the three-way valve 2 are respectively connected to a feed pipe 3 and a steam pipe 4. An ultraviolet germicidal lamp 5 is installed on the inner wall of the tank body 1. The feed inlet allows material or steam to be introduced into the tank body 1. During material crystallization, the valve connecting to the feed pipe 3 is opened via the three-way valve 2, while the valve connecting to the steam pipe 4 is closed, allowing the feed pipe 3 to introduce crystallized material into the tank body 1. During cleaning and disinfection of the tank body 1, the valve connecting to the steam pipe 4 is opened via the three-way valve 2, while the valve connecting to the feed pipe 3 is closed, allowing the steam pipe 4 to introduce steam into the tank body 1 for cleaning and disinfection. By installing the ultraviolet germicidal lamp 5 on the inner wall of the tank body 1, the ultraviolet germicidal lamp 5 can be turned on after steam cleaning and disinfection of the tank body 1, thus ensuring more thorough disinfection of the interior of the crystallization tank 1.

[0018] A stirring shaft 6 is rotatably installed inside the tank body 1. Both ends of the stirring shaft 6 are rotatably connected to the tank body 1 and extend beyond it. One end of the stirring shaft 6 is connected to a stirring motor, and the other end is connected to a water inlet pipe 7 via a rotary joint 13. The stirring shaft 6 has a cleaning chamber 12 communicating with the water inlet pipe 7. The cleaning chamber 12 is a blind hole. Multiple nozzles 8 are spaced along the length of the stirring shaft 6, and the nozzles 8 are connected to the cleaning chamber 12. This invention, by creating a cleaning chamber 12 at one end of the stirring shaft 6 and installing multiple nozzles 8 on it, allows for more convenient cleaning of the inside of the tank body 1. Compared to current crystallization tanks where water is directly poured into the crystallization tank for cleaning, this method is more thorough and convenient. During cleaning, the stirring shaft 6 rotates under the drive of the motor. During rotation, the nozzles 8 on the stirring shaft 6 can clean the inner wall of the tank body 1 from 360 degrees.

[0019] A cleaning water pipe 9 is installed on the top of the inner wall of the tank 1, and multiple downward-opening nozzles 8 are installed at intervals on the cleaning water pipe 9. In this invention, the nozzles 8 on the cleaning water pipe 9 open downwards and are directly facing the stirring shaft 6. During cleaning, water can be supplied to the cleaning water pipe 9 after the nozzles 8 on the stirring shaft 6 have finished cleaning, so that the nozzles 8 on the cleaning water pipe 9 can clean the rotating stirring shaft 6.

[0020] In this invention, during cleaning, cleaning water is first introduced into the stirring shaft 6, and the inner wall of the tank 1 is cleaned through the nozzles 8 on the stirring shaft 6. After the nozzles 8 on the stirring shaft 6 have finished cleaning, the flow of cleaning water into the cleaning chamber 12 of the stirring shaft 6 is stopped, and cleaning water is introduced into the cleaning water pipe 9. The nozzles 8 on the cleaning water pipe 9 clean the stirring shaft 6. After the stirring shaft 6 is cleaned, cleaning water can be introduced into the tank 1 again for cleaning. After the water in the tank 1 is drained, steam is introduced into the tank 1 for cleaning, sterilization and disinfection for a certain period of time. Finally, after the steam is stopped, the ultraviolet germicidal lamp 5 in the tank 1 is turned on to carry out more thorough sterilization and disinfection.

[0021] The outer side of the tank body 1 is provided with a jacket 10. The jacket 10 of this invention is provided with a cooling water coil, which can cool the tank body 1.

[0022] An ultraviolet germicidal lamp 5 is installed at the top of the inner wall of the tank 1, and an ultraviolet germicidal lamp 5 is installed at the bottom of the inner wall of the tank 1. In this invention, ultraviolet germicidal lamps 5 are installed at both the top and bottom of the inner wall of the tank 1.

[0023] An eyepiece 11 is also installed on the tank body 1. The eyepiece 11 of this utility model allows people to easily observe the internal condition of the crystallization tank.
