Description

Technical Field

[0001] The utility model relates to the technical field of automatic medicine dispensing, in particular to an automatic medicine dispensing device utilizing a venturi tube. Background Art

[0002] Due to the harm of African swine fever, the logistics and transportation of feed mills and pig farms will accelerate the spread of the African swine fever virus. Necessary logistics and transportation cannot be interrupted. Therefore, feed mills and some pig farms are currently equipped with disinfection facilities for vehicles entering and leaving. Disinfectant is sprayed on the body of the vehicle through a high-pressure pump to kill the African swine fever virus.

[0003] However, the disinfectant currently used is a 500PPM Virkon solution, which is diluted online with Virkon stock solution and water. Traditionally, Virkon stock solution is added to water using a pump or a water-powered self-priming pump, but their principle is to absorb the solution through rotation or reciprocating motion of the sealing ring. Virkon liquid with a high concentration is highly corrosive, so this type of equipment is prone to damage and is expensive.

[0004] Therefore, those skilled in the art provide an automatic dispensing device using a venturi tube to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides:

[0006] An automatic dispensing device using a venturi tube comprises: a constant pressure water supply system; a filter is installed in the pool body of the constant pressure water supply system, and a disinfectant tank is connected to one end of the constant pressure water supply system; a regulating valve is installed on the pipe body between the constant pressure water supply system and the disinfectant tank; a float switch is installed on the pipe body where the disinfectant tank and the constant pressure water supply system are installed.

[0007] Preferably: the pipe body between the constant pressure water supply system and the disinfectant tank is connected with a venturi tube body, and a second regulating valve is installed between the venturi tube body and the pipe body between the constant pressure water supply system and the disinfectant tank.

[0008] Preferably: the bottom of the Venturi tube body is connected to an original medicine box through a tube body, and a regulating valve three is installed on the tube body connecting the original medicine box and the Venturi tube body.

[0009] Preferably: a high-pressure pump connecting pipe is connected through the bottom side of the disinfectant tank.

[0010] Preferably: one end of the constant pressure water supply system is connected to a water inlet pipe body.

[0011] The water inlet pipe body is connected to the tap water pipe.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, when liquid passes through the pipeline of the venturi tube body through the constant pressure water supply system, an area with higher flow rate and lower pressure is formed at the opening of the pipeline. The pressure in this area is lower than the pressure of the liquid inside the pipeline, forming a negative pressure area, which is convenient for shunting the pipeline between the constant pressure water supply system and the disinfectant tank into the pipeline of the venturi tube body to stabilize the water pressure. Negative pressure is generated when passing through the venturi tube body, and the Weiken disinfectant original solution in the original medicine box is absorbed. After mixing with water in the pipeline, it flows into the disinfectant tank to automatically adjust the pressure and dispense medicine. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiment:

[0020] See also Figure 1 In this embodiment, an automatic dispensing device using a venturi tube is provided, comprising: a constant pressure water supply system 1; a filter is installed in the pool body of the constant pressure water supply system 1, and a disinfectant tank 9 is connected to one end of the constant pressure water supply system 1; a regulating valve 2 is installed on the pipe body between the constant pressure water supply system 1 and the disinfectant tank 9;

[0021] The pipe body between the disinfectant tank 9 and the constant pressure water supply system 1 is equipped with a float switch 8; the pipe body between the constant pressure water supply system 1 and the disinfectant tank 9 is connected to a venturi tube body 5, and a regulating valve 2 4 is installed between the venturi tube body 5 and the pipe body between the constant pressure water supply system 1 and the disinfectant tank 9;

[0022] The bottom of the Venturi tube body 5 is connected to the original medicine box 7 through the tube body, and a regulating valve 3 6 is installed on the tube body connecting the original medicine box 7 and the Venturi tube body 5; the bottom side of the disinfectant tank 9 is connected to a high-pressure pump connecting pipe 10; one end of the constant pressure water supply system 1 is connected to the water inlet pipe body 3.

[0023] Working principle:

[0024] Principle of the Venturi tube 5: When the liquid passes through the pipe of the Venturi tube 5 through the constant pressure water supply system 1, a region with higher flow rate and lower pressure is formed at the opening of the pipe. The pressure in this region is lower than the pressure of the liquid inside the pipe, forming a negative pressure region;

[0025] Due to the existence of the negative pressure area, the liquid will be sucked into the pipe and flow along the pipe. During the flow process, the space inside the pipe becomes smaller, thereby accelerating the flow of the liquid and increasing its kinetic energy.

[0026] At the outlet of the pipeline, the liquid is forced to pass through a narrower section of the pipeline, so the liquid velocity will further increase and the pressure will decrease. Finally, the liquid flows out through the outlet of the venturi tube body 5, the flow velocity gradually slows down, and the pressure gradually returns to the initial value.

[0027] The venturi tube body 5 has no reciprocating motion due to its characteristics, so there is no significant wear during the drug inhalation process, and the venturi tube is cheap on the market and easy to install;

[0028] The filter in the constant pressure water supply system 1 filters the water source to prevent impurities in the water from affecting the quality. The constant pressure water supply system 1 is used to supply a stable water pressure to the pipeline connected to the disinfectant tank 9, and the water pressure can be set according to the needs of the regulating valve 2 (according to the water pressure requirements required for the operation of the venturi tube body 5);

[0029] The stable water pressure in the pipeline between the constant pressure water supply system 1 and the disinfectant tank 9 is diverted into the pipeline of the venturi tube 5, and negative pressure is generated when passing through the venturi tube 5, absorbing the Wei Ke disinfectant stock solution in the original medicine box 7, and after mixing with water in the pipeline, it flows into the disinfectant tank 9;

[0030] The regulating valve 1 2, regulating valve 2 4, and regulating valve 3 6 cooperate with each other to control the amount of water flowing through the venturi tube body 5 and the amount of medicine fed from the original medicine box 7 to the venturi tube body 5 to control the concentration of the prepared medicine, so that the concentration of the disinfectant tank 9 reaches the required concentration;

[0031] After the liquid level inside the disinfectant tank 9 reaches the float switch 8, the supply pipeline is closed and the system stops spraying.

[0032] In the present invention, unless otherwise clearly stipulated and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
