Description

Technical Field

[0001] This application relates to the field of bottle cap sterilization technology, and in particular to an automatic disinfectant dispensing device. Background Technology

[0002] Aseptic cold filling technology for PET bottled beverages refers to filling aseptic materials into aseptic packaging materials in an aseptic environment. The packaging materials refer to PET bottles and bottle caps. Therefore, the degree of sterilization of bottle caps has a great impact on high-requirement production lines such as aseptic cold filling and ultra-clean filling, and the sterilization method of bottle caps determines their sterilization effect.

[0003] In existing technologies, common bottle cap sterilization devices mainly include a closed conveying orifice and a sterilization device connected to the conveying orifice. The conveying orifice contains, in sequence, a sterile air blowing and turning device, a sterile water spraying device, and a sterile air drying device. A bottle cap conveying device also penetrates the conveying orifice. A cap feeder connected to the sterilization device is located above it. The sterilization device includes an immersion tank containing a sterilization track composed of at least two involute tracks. At least one disinfectant spraying component is located above the immersion tank. It should be noted that the disinfectant used for bottle cap sterilization is Woyang acetic acid disinfectant.

[0004] Peracetic acid is an environmentally friendly and highly effective disinfectant and sterilizer that can rapidly kill bacteria, viruses, fungi, and spores. It can be used for disinfection of packaging materials and the environment, and its application in the food industry, especially the beverage industry, is becoming increasingly widespread.

[0005] Typically, most manufacturers manually prepare peracetic acid disinfectant solution. The solution is pre-mixed in a mixing tank, and during production, the concentration is periodically monitored using test strips. Based on the test results, concentrated peracetic acid solution is added to the tank to maintain the correct concentration. This manual addition of concentrated peracetic acid solution often results in large fluctuations in concentration and is susceptible to human error, potentially leading to production quality accidents. This poses a significant risk, impacting product quality and warrants improvement. Utility Model Content

[0006] In order to improve the uniformity of the concentration of the prepared disinfectant and ensure the disinfection effect, this application provides an automatic disinfectant preparation device.

[0007] The automatic disinfectant mixing device provided in this application adopts the following technical solution:

[0008] An automatic disinfectant mixing device mainly includes a frame, a mixing tank, and a dosing tank.

[0015] By adopting the above technical solution, when preparing disinfectant, the operator can input a start signal through the control panel on the frame. The dosing control unit connects to the dosing pipeline and continuously and quantitatively adds the disinfectant solution into the mixing tank. The water supply control unit connects to the water supply pipeline and continuously and quantitatively injects water into the mixing tank. Through the setting of the first and second spray heads, the water and disinfectant solution can be pre-mixed after being sprayed out. When used with the stirring mechanism, the water and disinfectant solution can be further mixed, so that the disinfectant solution is evenly mixed and dispersed in the water, thereby improving the disinfection effect of the disinfectant solution. When the disinfectant solution level in the mixing tank reaches a certain height, the liquid supply control unit automatically connects to the liquid supply pipeline and continuously supplies disinfectant solution to the soaking tank of the sterilization device. By coordinating and using the control panel, dosing control unit, water supply control unit, liquid supply control unit, and stirring mechanism, the technology of automatic and online preparation of disinfectant can be achieved, eliminating the need for operators to manually measure and prepare the disinfectant solution, improving production efficiency, accurately controlling the dosage of disinfectant and water, and precisely controlling the concentration stability of the disinfectant solution through fully online preparation, thus ensuring the disinfection effect of the sterilization device on the bottle cap.

When the disinfectant level in the mixing tank 2 reaches a certain height, the liquid supply control unit automatically connects to the liquid supply pipe 21 and continuously supplies disinfectant to the soaking tank of the sterilization device 4.

[0044] By combining and using the control panel 11, the dosing control unit, the water supply control unit, the liquid supply control unit, and the stirring mechanism 28, the technology of automatic and online preparation of disinfectant can be achieved, eliminating the need for operators to manually measure and prepare the disinfectant, thus improving production efficiency.

[0052] When the operator inputs a start signal through the control panel 11, the first solenoid valve 251 and the second solenoid valve 261 are connected to the water supply pipe 25 and the dosing pipe 26, respectively. The water pump 252 and the dosing pump 262 add water and medicine to the mixing tank 2 in a quantitative and continuous manner according to the set ratio. As the liquid level of the mixture in the mixing tank 2 rises, the liquid level sensor 27 detects the liquid level of the water and medicine mixture in real time.
