Description

Technical Field

[0001] The present invention relates to the technical field of disinfectant dilution, and specifically to a disinfectant dilution device. Background Art

[0002] Some disinfectants may generate heat during dilution. Commonly, disinfectants that generate heat include chlorine-containing disinfectants such as 84 disinfectant and peracetic acid, and acidic disinfectants such as concentrated sulfuric acid. Taking 84 disinfectant as an example, its main component is sodium hypochlorite. Sodium hypochlorite will undergo a hydrolysis reaction in water to generate hypochlorous acid and sodium hydroxide, and the hydrolysis process is an exothermic process. When diluting 84 disinfectant, as sodium hypochlorite contacts and reacts with water, heat will be released, resulting in an increase in the solution temperature. Therefore, the problem of heat dissipation needs to be considered during the disinfection process of disinfectants.

[0003] Some existing dilution devices simply mix disinfectant and water directly. This causes the heat generated during the mixing of a large amount of liquid to accumulate in a short time, resulting in an increase in the liquid temperature. However, the temperature rise may affect the disinfection effect of the disinfectant. Therefore, it is necessary to improve the existing dilution devices for the problem of heat volatilization during the dilution process. Summary of the Invention

Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In one embodiment, please refer to Figures 1 - 10 , a disinfectant dilution device, including a base 1, a solution holding mechanism 2 and a mixing and dilution mechanism 3;

[0028] The solution holding mechanism 2 includes a dilution tank 11 arranged above the base 1. The dilution tank 11 is a cylindrical container with an open top. The dilution tank 11 is placed in the middle above the base 1 and can be freely taken.

[0029] The mixing and diluting mechanism 3 includes a back plate 12 fixedly connected to the side of the base 1. The back plate 12 is vertically arranged on the upper rear side of the base 1. In order to reduce the overall weight of the back plate 12, a smaller plate is selected to make the back plate 12, and legs are arranged on the left and right sides of the lower end of the back plate 12 to be fixedly connected to the base 1, so that the weight of the entire dilution device can be reduced while ensuring the structural stability of the back plate 12. Liquid storage tanks 13 are vertically arranged on the left and right sides of the front of the back plate 12. One liquid storage tank 13 is used to hold disinfectant, and the other liquid storage tank 13 is used to hold The liquid storage tank 13 is provided with a vertically placed buffer tube 17 at the front side thereof. The liquid storage tank 13 and the buffer tube 17 are both cylindrical structures with an opening at the top. The rear end of the connecting tube 16 is connected to the lower end of the connecting tube 16 at the lower end of the connecting tube 16, and the front end of the connecting tube 16 is connected to the lower end of the buffer tube 17, so that the liquid storage tank 13 and the buffer tube 17 are connected. A downwardly facing discharge port 14 is provided in the middle of the connecting tube 16. An extrusion piston 20 is slidably connected inside the liquid storage tank 13, and a liquid inlet one-way valve 21 is provided in the middle of the extrusion piston 20, so that the liquid can only be discharged from the upper end of the extrusion piston 20. The liquid in the liquid storage tank 13 flows through the extrusion piston 20 to the bottom of the extrusion piston 20, and a discharge check valve 15 is provided at the rear end of the connecting pipe 16, so that the liquid can only enter the connecting pipe 16 from the liquid storage tank 13 through the discharge check valve 15. Therefore, when the extrusion piston 20 moves downward, the liquid at the bottom of the liquid storage tank 13 enters the connecting pipe 16 through the discharge check valve 15 and is discharged through the discharge port 14. However, after the extrusion piston 20 moves downward once, the liquid in the liquid storage tank 13 that enters the connecting pipe 16 at a time is large, and the liquid cannot be discharged from the connecting pipe 16 in time. At this time, the liquid will enter the buffer tube 17 through the connecting tube 16, and the liquid in the buffer tube 17 can be continuously discharged through the drain port 14, so as to achieve the effect of liquid buffering. A lifting drive assembly 19 is set on the rear side of the back plate 12. The lifting drive assembly 19 can drive the extrusion piston 20 to move up and down continuously, so that the liquid in the liquid storage tank 13 can intermittently enter the connecting tube 16 for discharge. The top of the liquid storage tank 13 is also open, so when it is necessary to replenish the liquid, the liquid replenishment action can be performed through the opening at the top of the liquid storage tank 13. In order to facilitate the lifting drive assembly 19 to drive the extrusion piston 20 to move, a suspension bracket 18 is set above the extrusion piston 20. The lower end of the suspension bracket 18 is a U-shaped structure, and the U-shaped structure at the lower end of the suspension bracket 18 avoids the liquid inlet check valve 21.

[0030] In a case of this embodiment, a constant-pressure piston 22 is slidably connected inside the buffer tube 17. The lower surface of the constant-pressure piston 22 is fixedly connected to the upper end of a vertically arranged pull rod 23. The middle part of the pull rod 23 is slidably connected to the bottom of the buffer tube 17. A stirring head 24 is arranged at the lower end of the pull rod 23, and a spiral blade is arranged on the outer side of the stirring head 24. The liquid inside the dilution tank 11 is mixed by the up-and-down movement of the stirring head 24 with the spiral blade. Moreover, the constant-pressure piston 22 floats on the surface of the liquid inside the buffer tube 17. Therefore, when the liquid inside the liquid storage tank 13 enters the buffer tube 17, the constant-pressure piston 22 moves upward, and when the liquid inside the buffer tube 17 is discharged, the constant-pressure piston 22 moves downward. Thus, during the operation of the entire device, the constant-pressure piston 22 drives the stirring head 24 to move up and down, so as to stir the liquid inside the dilution tank 11 through the stirring head 24. And in order to facilitate the placement of the dilution tank 11, the rising distance of the stirring head 24 is set. When the stirring head 24 rises to the highest position, the bottom end of the stirring head 24 is higher than the upper edge of the dilution tank 11, so that after the stirring head 24 is lifted, the dilution tank 11 can be freely placed on the upper surface of the base 1, and then the stirring head 24 is released, and the stirring head 24 can fall back into the dilution tank 11.

[0031] In one case of this embodiment, the lifting drive assembly 19 includes a mounting seat 25 arranged in the middle of the rear side surface of the back plate 12. The mounting seat 25 is arranged in the front-back direction. On the left and right sides of the upper surface of the mounting seat 25, vertical plates 26 are arranged. The upper ends of the vertical plates 26 are rotatably connected to a main shaft 27 arranged in the left-right direction. Both the left and right ends of the main shaft 27 are provided with deflection beams 28. The middle of the deflection beam 28 is fixedly connected to the end of the main shaft 27. On the side of the deflection beam 28 away from the main shaft 27, a sliding groove 39 is provided. A rotating seat 29 is slidably connected to the middle of the sliding groove 39. Fixed plates 41 are arranged at both ends of the sliding groove 39. The two fixed plates 41 are respectively rotatably connected to both ends of a liquid level adjusting screw rod 40. The middle of the liquid level adjusting screw rod 40 is threadedly connected to the middle of the rotating seat 29. Thus, by rotating the liquid level adjusting screw rod 40, the position of the rotating seat 29 in the sliding groove 39 can be adjusted, that is, the distance between the rotating seat 29 and the main shaft 27 can be adjusted. The lower end of a push rod 30 is rotatably connected to the outside of the rotating seat 29. The upper end of the push rod 30 is rotatably connected to the lower end of a vertically arranged ejector rod 31. The middle of the ejector rod 31 is slidably connected to an extension plate 32 fixedly connected to the back plate 12. The rear end of a suspension bracket 18 is fixedly connected to the upper end of the ejector rod 31. Therefore, when the main shaft 27 drives the deflection beam 28 to rotate, the deflection beam 28 makes the ejector rod 31 and the suspension bracket 18 move up and down through the push rod 30, that is, pushes the extrusion piston 20 to move up and down. And since the distance between the rotating seat 29 and the main shaft 27 can be adjusted, that is, the rotation radius of the rotating seat 29 can be adjusted, the up and down movement distance of the extrusion piston 20 can be adjusted. Thus, the volume of the liquid in the liquid storage tank 13 entering the liquid discharge port 14 each time can be freely adjusted. Therefore, during a single extrusion process, a fixed volume of disinfectant and water can be set for mixing, realizing the setting of different concentration dilutions. And in order to make the deflection beam 28 rotate better, a counterweight 38 is arranged at the end of the deflection beam 28 away from the rotating seat 29. The counterweight 38 and the rotating seat 29 are respectively arranged on both sides of the main shaft 27, so that the rotation of the deflection beam 28 is more stable. The orientations of the two deflection beams 28 on the left and right sides are set to be opposite, that is to say, when the rotating seat 29 on one side moves up, the rotating seat 29 on the other side will move down. Thus, the liquid storage tanks 13 on the left and right sides can alternately extrude disinfectant and water, improving the mixing effect.A bearing seat 33 is provided on the lower surface of the mounting seat 25. The bearing seat 33 is rotatably connected to a rotating shaft 34. The middle part of the rotating shaft 34 is fixedly connected to a driving pulley 35. The driving pulley 35 is connected to a driven pulley 37 through a synchronous belt 36. The driven pulley 37 is fixedly connected to the middle part of the main shaft 27. Thus, the rotating shaft 34 can make the main shaft 27 rotate by means of belt transmission. A rotating wheel is provided at the end of the rotating shaft 34, so that the operator can drive the main shaft 27 to rotate by manually rotating the rotating wheel. A driving motor can also be provided on the mounting seat 25. The output shaft of the driving motor is fixedly connected to the end of the rotating shaft 34. Therefore, the driving motor can drive the main shaft 27 to rotate. An auxiliary bracket 42 fixedly connected to the back plate 12 is provided at the end of the mounting seat 25. The auxiliary bracket 42 can support the mounting seat 25, avoid the mounting seat 25 being in the state of a cantilever beam, and improve the stability of the mounting seat 25.

[0032] In one case of this embodiment, a baffle 10 is provided on the rear side of the upper surface of the base 1. Therefore, when the dilution tank 11 is placed on the base 1, it can be pushed backward. When the rear side of the diluent abuts against the baffle 10, the diluent can stop moving, thus achieving a limiting effect. Clamping assemblies 9 are provided on both the left and right sides of the base 1. The clamping assemblies 9 can be used to fix the dilution tank 11. The clamping assembly 9 includes clamping rotating seats 6 provided on both the left and right sides of the base 1. The clamping rotating seats 6 are rotatably connected to the middle parts of the deflecting clamping plates 5. The front ends of the deflecting clamping plates 5 are inclined towards the direction close to the center of the base 1. A guide wheel 4 is provided at the front end of the deflecting clamping plate 5. One end of a buffer spring 7 is connected to the rear end of the deflecting clamping plate 5. The other end of the buffer spring 7 is provided with a fixed block 8 fixedly connected to the base 1. Therefore, when the dilution tank 11 is placed on the base 1 and pushed backward, the dilution tank 11 will push the deflecting clamping plates 5 on both sides to open through the guide wheel 4. When the guide wheel 4 passes over the dilution tank 11, the side surfaces of the deflecting clamping plates 5 will abut against the dilution tank 11. And because the buffer spring 7 will push the deflecting clamping plate 5 to rotate towards the direction of the dilution tank 11, the deflecting clamping plates 5 on both sides will push the dilution tank 11 to move towards the center direction of the base 1, achieving a centering effect.

[0033] During the implementation of this embodiment, first rotate the liquid level adjusting screw rod 40 to adjust the position of the rotating seat 29 on the deflection beam 28, that is, adjust the volume of the liquid extruded by the extrusion pistons 20 on both sides, so as to adjust the dilution concentration. After the adjustment is completed, close the throttle valve provided on the connecting pipe 16 to prevent the liquid in the liquid storage tank 13 from flowing into the connecting pipe 16. Add water and disinfectant to the liquid storage tanks 13 on both sides respectively. After passing through the inlet check valve 21, the water and disinfectant fill the entire liquid storage tank 13. At this time, lift the stirring head 24, place the dilution tank 11 on the base 1 and push it backward. The dilution tank 11 moves below the stirring head 24, and then release the stirring head 24. The stirring head 24 falls into the interior of the dilution tank 11, and the entire preparation work is completed.

[0034] Open the throttle valve of the connecting pipe 16 and rotate the rotating shaft 34. The rotating shaft 34 drives the main shaft 27 to rotate through belt transmission. The main shaft 27 makes the extrusion pistons 20 on both sides move up and down alternately through the deflection beam 28 and the ejector rod 31, so that the liquid in the liquid storage tanks 13 on both sides is continuously discharged. The liquid continuously flows into the interior of the dilution tank 11 through the liquid discharge port 14, so as to realize the sequential injection of water and disinfectant on both sides into the dilution tank 11 for dilution treatment of the disinfectant.

[0035] As the liquid continuously enters the buffer pipe 17 intermittently, the constant pressure piston 22 moves up and down continuously, driving the stirring head 24 to move up and down, so that the stirring head 24 stirs the liquid inside the dilution tank 11, further improving the mixing and dilution effect of the disinfectant inside the dilution tank 11. When the volume of the diluted disinfectant meets the requirements, close the throttle valve of the connecting pipe 16. After waiting for the liquid in the buffer pipe 17 to be completely discharged, lift the stirring head 24 upward and take out the dilution tank 11.

[0036] The present invention is applicable to a disinfectant dilution device. The lifting drive assembly 19 enables the two extrusion pistons 20 to intermittently squeeze the disinfectant and water in the liquid storage tank 13 into the dilution tank 11, so that the disinfectant can be diluted in small volumes in batches, enabling the heat generated during the dilution process of the disinfectant to be conducted away in time, avoiding the sharp rise in the temperature of the liquid. At the same time, during the process of squeezing the liquid, the constant pressure piston 22 drives the stirring head 24 to move up and down inside the dilution tank 11, further improving the liquid mixing effect, that is, improving the dilution effect of the disinfectant.

[0037] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes that fall within the meaning and scope of the equivalent elements of the claims within the present invention.
