Description

Technical Field

[0001] This utility model relates to the field of sustained-release bactericides, specifically to a sustained-release device for bactericides. Background Technology

[0002] Fungicides are a class of pesticides used to control plant diseases caused by various pathogenic microorganisms. They generally refer to fungicides. There are many types of fungicides, which can be classified into liquid fungicides and solid fungicides based on their state. Currently, to slow down the release rate of fungicides and increase the sterilization time, it is necessary to set up corresponding slow-release devices. A search revealed existing technology (publication number: CN202321248252.7) for a fungicide slow-release device. The document describes that "by adjusting the setting of the unit, one of the two storage tanks is filled with pure water, and the other with undiluted fungicide. The mixing tank contains diluted fungicide..." The process involves rotating a rotating ring, which in turn drives a central disc to rotate via a connecting ring. The varying degrees of overlap between the multiple circular holes result in different water inflow rates. Under the influence of the trapezoidal ring, the undiluted disinfectant flows out in a measured amount. This ensures that the ratio of undiluted disinfectant to purified water flowing into the mixing tank is the same within the same timeframe, resulting in a uniform concentration of the diluted disinfectant. Furthermore, the flow rate of purified water can be adjusted by rotating the rotating ring, thereby controlling the concentration of the diluted disinfectant. However, existing technologies require manual monitoring to control the amount of disinfectant released and diluted each time, making it difficult to automatically control this process. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a slow-release device for bactericides is provided to solve the problem that in existing technologies, the amount of bactericide released for each dilution needs to be manually controlled by the operator, making it difficult to automatically control the amount of bactericide released.

[0004] To achieve the above objectives, a slow-release device for a bactericide is provided, comprising: a slow-release mixing tank, a bactericide tank, and a water tank, wherein the bactericide tank and the water tank are fixed to the upper surface of the slow-release mixing tank.

[0005] The inner wall of the slow-release mixing tank is fitted with a liquid level float plate, and a sealing ring is embedded and fixed on the outer side of the liquid level float plate. The upper surface of the liquid level float plate is connected to the slow-release mixing tank through a limiting plate. The upper end of the liquid level float plate is connected to a discharge pipe through a telescopic pipe. Limiting pressure plates are fixed on the front and rear sides of the limiting plate. The lower end of the limiting pressure plate is connected to the upper surface of the liquid level float plate through a return spring.

[0006] Furthermore, a controller is installed on the front surface of the slow-release mixing box, and a distance sensor is embedded in the upper surface of the slow-release mixing box; and the distance sensor is located on the left side of the limiting plate.

[0007] Furthermore, the disinfectant tank is fixedly located on the left side of the water tank, and both the disinfectant tank and the water tank are equipped with a discharge pipe at their lower ends, with an electric valve installed on the surface of the discharge pipe.

[0008] Furthermore, the disinfectant tank is fixedly located on the left side of the water tank, and both the disinfectant tank and the water tank are equipped with a discharge pipe at their lower ends, with an electric valve installed on the surface of the discharge pipe.

[0009] Furthermore, a rectangular base plate is symmetrically arranged on the lower end of the liquid level float, a drain port is opened on the inner side of the liquid level float, and a row of return springs are equidistantly connected to the lower surface of the limiting pressure plate.

[0010] Furthermore, the upper end of the drain port is connected to a telescopic pipe, and the lower end is connected to a base plate. The limiting pressure plate and the limiting plate are distributed in an I-shape at the upper end of the liquid level float.

[0011] Furthermore, the liquid level float, limiting plate, telescopic pipe, sealing ring, limiting pressure plate, and return spring constitute the liquid level lifting and lowering detection mechanism of the slow-release mixing tank.

[0012] The beneficial effects of this utility model are as follows: the bactericide slow-release device of this utility model uses a telescopic pipe to inject bactericide and purified water into the lower end of the liquid level float. The water pressure of the injected bactericide and purified water pushes the liquid level float to rise continuously. The dilution of bactericide is automatically stopped according to the rising height. At the same time, the limit plate elastically presses down the local upward tilt of the float during the rising of the liquid level float, which facilitates the automatic shutdown of the release of bactericide. This realizes the batch release and slow-release storage of bactericide, saves labor costs and excessive waste of bactericide, and facilitates more precise control of the bactericide dilution.

Detailed Implementation

[0018] Reference Figures 1 to 4 As shown, this utility model provides a slow-release device for a bactericide, including: a slow-release mixing tank 1, a bactericide tank 2, and a water tank 21. The bactericide tank 2 and the water tank 21 are fixed to the upper surface of the slow-release mixing tank 1.

[0019] The inner wall of the slow-release mixing tank 1 is fitted with a liquid level float 3. A sealing ring 34 is embedded and fixed on the outer side of the liquid level float 3. The middle of the upper surface of the liquid level float 3 is connected to the slow-release mixing tank 1 through a limiting plate 31. The upper end of the liquid level float 3 is connected to a discharge pipe 23 through a telescopic pipe 33. Limiting pressure plates 5 are fixed on the front and rear sides of the limiting plate 31. The lower end of the limiting pressure plate 5 is connected to the upper surface of the liquid level float 3 through a return spring 51.

[0020] When diluting a portion of the disinfectant, after setting the dilution amount, the controller 11 opens the electric valve 22 to discharge the disinfectant tank 2 and the water tank 21. The disinfectant and purified water are discharged through the telescopic pipe 33 to the area below the liquid level float 3. As the disinfectant and purified water are discharged, the liquid level float 3 is pushed upward, causing the distance sensor 13 to detect the lifting height of the limit plate 31. The controller 11 controls the limit plate 31 to reach the preset height value based on the value detected by the distance sensor 13, and then stops the release of the disinfectant. During the release process, the stirrer 4 is started to mix the disinfectant and purified water. After mixing, the mixture is discharged through the pipe connected to the outlet 12. The remaining disinfectant in the disinfectant tank 2 is released slowly and saved for the next use.

[0021] In this embodiment, a controller 11 is installed on the front surface of the slow-release mixing tank 1, and a distance sensor 13 is embedded in the upper surface of the slow-release mixing tank 1; the distance sensor 13 is located on the left side of the limiting plate 31. A liquid outlet 12 is provided at the right end of the slow-release mixing tank 1, and a stirring motor 41 is installed on the lower end surface of the slow-release mixing tank 1. A stirrer 4 is shaft-connected to the upper end of the stirring motor 41; the stirrer 4 is located in the inner cavity of the slow-release mixing tank 1.

[0022] In a preferred embodiment, the controller 11 controls the stirring motor 41 to start, causing the stirrer 4 to mix the liquid in the slow-release mixing tank 1, ensuring that the disinfectant is fully diluted. The distance sensor 13 is used to detect the lifting height of the limit plate 31 and transmits the detected value to the controller 11, so that the controller 11 controls the limit plate 31 to reach a preset height value and then stops the release of the disinfectant.

[0023] In this embodiment, the bactericide tank 2 is fixedly distributed on the left side of the water tank 21. Both the bactericide tank 2 and the water tank 21 are equipped with a discharge pipe 23 at their lower ends, and an electric valve 22 is installed on the surface of the discharge pipe 23.

[0024] In a preferred embodiment, the flow rate and on / off state of the disinfectant tank 2 and the water tank 21 are controlled by an electric valve 22. The electric valve 22 is electrically connected to the controller 11.

[0025] In this embodiment, a rectangular base plate 32 is symmetrically arranged on the lower end of the liquid level float 3, and a drain port 35 is opened on the inner side of the liquid level float 3. A row of return springs 51 are equidistantly connected to the lower surface of the limiting pressure plate 5. The upper end of the drain port 35 is connected to a telescopic pipe 33, and the lower end is connected to the base plate 32. The limiting pressure plate 5 and the limiting plate 31 are distributed in an I-shape at the upper end of the liquid level float 3.

[0026] As a preferred implementation, the base plate 32 facilitates the elevation of the liquid level float 3, preventing it from obstructing the rotating agitator 4 when it reaches its lowest point. The telescopic pipe 33 allows the discharge of disinfectant and purified water from the disinfectant tank 2 and water tank 21 to the area below the liquid level float 3, where the water pressure from the disinfectant and purified water pushes the float 3 upwards. The I-shaped limiting plates 5 provide balanced support for the liquid level float 3, preventing one side of the float 3 from tilting upwards and getting stuck.

[0027] In this embodiment, the liquid level float 3, the limiting plate 31, the telescopic pipe 33, the sealing ring 34, the limiting pressure plate 5, and the return spring 51 constitute the liquid level lifting and lowering detection mechanism of the slow-release mixing tank 1.

[0028] As a preferred embodiment, the liquid level rise and fall detection mechanism of the slow-release mixing tank 1 facilitates the determination of the solution volume in the slow-release mixing tank 1, facilitates the control of the dilution amount of the bactericide or the automatic dilution of the quantitative bactericide solution after use, realizes the batch release and slow-release storage of the bactericide, and improves the practicality of the bactericide slow-release device.

[0029] The bactericide slow-release device of this utility model can effectively solve the problem of difficulty in automatically controlling the release and dilution of bactericides, facilitate the automatic shutdown of bactericide release, realize the batch release and slow-release storage of bactericides, save labor costs and excessive waste of bactericides, and facilitate more precise control of bactericide dilution. It is suitable for bactericide slow-release devices.
