Description

Technical Field

[0001] The utility model relates to the technical field of automatic disinfection devices, in particular to a timed and quantitative floor drain disinfection device. Background Art

[0002] In food processing and pharmaceutical production workshops, regular floor drain disinfection is essential to maintain a clean environment and improve product quality. As a crucial interface between the drainage system and the workshop floor, floor drains are a breeding ground for bacteria, viruses, and other microorganisms. Especially during the production process, floor drains can harbor contaminants, increasing the risk of product contamination. Therefore, cleaning and disinfecting floor drains is crucial to maintaining a hygienic production environment and ensuring product quality.

[0003] Currently, manual disinfection is mainly used, which requires manual preparation of the disinfectant and regular addition to the floor drain, which places high demands on management and training. In order to avoid cross-contamination, companies may need to assign dedicated personnel to clean and disinfect the floor drains. This not only takes up valuable human resources, but also makes it difficult to ensure the consistency and effectiveness of the disinfection work due to the uncertainty of manual operation. At the same time, some companies also arrange for production line operators to perform regular sanitation maintenance and floor drain disinfection. During the process, direct or indirect contact with the floor drain is inevitable, and contaminants may be inadvertently carried from one area to another, especially between clean areas and non-clean areas. The risk of cross-contamination is even more significant. Moreover, the frequency and effectiveness of manual disinfection are difficult to accurately control, and there may be problems with inadequate disinfection or excessive disinfection, all of which may have an impact on the environment and personnel health.

[0004] In order to improve the efficiency and safety of disinfection work, reduce the occupation of human resources, and effectively avoid the risk of cross contamination, how to design a floor drain disinfection device with simple structure, low cost and automatic timing and quantitative control is an urgent problem that technicians in this field need to solve. Utility Model Content

[0005] The utility model provides a timed and quantitative floor drain disinfection device, which solves the problems of low efficiency, human resource occupation, and potential safety and cross-contamination risks of existing manual floor drain disinfection through a relatively energy-saving technical solution.

[0006] The utility model solves the above technical problems with the following technical solutions: a timed and quantitative floor drain disinfection device comprising: a venturi ejector, a connecting pipe group, a disinfectant tank and a control system.

[0007] The two ends of the Venturi ejector are respectively provided with a liquid inlet and a liquid outlet, and a disinfectant pump inlet hole is provided on the side wall with a large cross-section; the connecting pipe group includes a first water pipe, a second water pipe and a disinfectant pipe, one end of the first water pipe is connected to the liquid inlet and the other end is connected to the water replenishment source; one end of the second water pipe is connected to the liquid outlet and the other end is connected to the water seal of the floor drain; one end of the disinfectant pipe is connected to the disinfectant pump inlet; the bottom end of the disinfectant tank is provided with a disinfectant outlet; the other end of the disinfectant pipe is connected to the disinfectant outlet; the control system includes a first solenoid valve, a second solenoid valve, a needle valve, a first time relay and a second time relay, the first solenoid valve is installed in the middle of the first water pipe; the second solenoid valve is installed in the middle of the second water pipe; the needle valve is installed in the middle of the disinfectant pipe; the first time relay is electrically connected to the second time relay, the first solenoid valve and the second solenoid valve respectively.

[0008] The beneficial effects of the utility model are as follows: according to the spraying cycle length and spraying disinfection amount of the food or drug workshop, the opening time of the first time relay, the closing time of the second time relay and the opening size of the needle valve are determined; when the first time relay is turned on, the second time relay, the first solenoid valve and the second solenoid valve are opened accordingly; when the fluid passes through the Venturi ejector, the dynamic pressure (velocity head) reaches the maximum value and the static pressure (resting pressure) reaches the minimum value at the narrowest part of its internal cross-section, resulting in an increase in liquid flow rate, a decrease in pressure, and a pressure difference; the pressure difference generates suction, which opens the needle valve and draws the disinfectant into the ejector; subsequently, the mixed disinfectant flows into the floor drain water seal through the second solenoid valve, completing the floor drain disinfection; when the set time of the second time relay is reached, the second time relay is closed, and at the same time, the first time relay, the first solenoid valve and the second solenoid valve are also closed, and the mixed disinfectant is temporarily poured into the floor drain water seal; this cycle is repeated until the next opening time of the first time relay is waited for.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, it also includes an air pipe and a third solenoid valve. A compressed air inlet hole is provided at the point where the cross-sectional area of ​​the Venturi ejector is smallest; one end of the air pipe is connected to the compressed air inlet hole and the other end is connected to the compressed air; the third solenoid valve is installed in the middle of the air pipe.

[0011] A further beneficial effect of the above method is that by introducing compressed air into the smallest cross-sectional area of ​​the Venturi ejector, the compressed air can be used to push the liquid inside the Venturi ejector, thereby accelerating the flow rate of the liquid inside the Venturi ejector.

[0012] Furthermore, the compressed air inlet is arranged at an angle to the air pipe to promote the liquid inside the Venturi ejector to accelerate the flow.

[0013] Furthermore, the opening of the needle valve is adjustable. BRIEF DESCRIPTION OF THE DRAWINGS
