[0052] See also Figure 1-5 The utility model provides a technical solution: a disinfectant mixing device, comprising a disinfectant mixing tank 1, which adopts a common mixing tank structure, can feed and discharge materials, and can stir the ingredients;

[0053] A connecting pipe 2 is fixedly connected to the lower end of the outer wall of the disinfectant mixing tank 1, and the connecting pipe 2 fixedly connected to the disinfectant mixing tank 1 serves as a sampling channel;

[0054] The negative pressure sampling tube 3 is sealed and slidably inserted into the connecting tube 2. The negative pressure sampling tube 3 is connected to the external negative pressure equipment and uses the negative pressure suction to extract the disinfectant to complete the sampling;

[0055] The outer wall of the negative pressure sampling tube 3 is uniformly provided with graduated grooves 4 along the length direction. The graduated grooves 4 are used to extend the negative pressure sampling tube 3 to different depths in the inner cavity of the disinfectant mixing tank 1. The depth of extension is controllable.

[0056] The negative pressure sampling tube 3 passes through the connecting tube 2 and extends to the middle of the inner cavity of the disinfectant mixing tank 1 for sampling;

[0057] The inner wall of the disinfectant mixing tank 1 is evenly and longitudinally fixed with a stirring spoiler 5, which disturbs the vortex of disinfectant stirred to the periphery by the inner cavity of the disinfectant mixing tank 1, so that the concentration difference between the periphery and the middle of the inner cavity of the disinfectant mixing tank 1 is reduced, further improving the accuracy of the average value data obtained by multiple sampling.

[0058] In some embodiments, in order to extend through the connecting tube 2 to the middle of the inner cavity of the disinfectant preparation tank 1 for sampling, the negative pressure sampling tube 3 includes:

[0059] The sampling tube body 31 has one end extending through the connecting tube 2 into the disinfectant preparation tank 1. The other end of the sampling tube body 31 is fixedly connected to an external threaded connector 32, which is used to connect to an external negative pressure device. In this embodiment, a vacuum pump is used.

[0060] A sealing ring 33 is evenly and fixedly sleeved on the outer wall of the sampling tube body 31 along the length direction, and the outer wall of the sealing ring 33 slides and fits with the inner wall of the connecting tube 2. The design of the sealing ring 33 prevents the disinfectant from leaking out of the gap between the sampling tube body 31 and the connecting tube 2;

[0061] The sampling tube body 31 is located in the disinfectant mixing tank 1 and is equipped with a negative pressure opening sealing structure 34 at one end. The vacuum pump exhausts the air inside the sampling tube body 31, and the negative pressure acts on the negative pressure opening sealing structure 34 to open it, allowing the disinfectant in the disinfectant mixing tank 1 to enter the sampling tube body 31.

[0062] A drain pipe 35 is fixedly connected to the bottom surface of the sampling tube body 31 at one end away from the disinfectant mixing tank 1;

[0063] The baffle 36 is fixedly assembled on the edge of the inner cavity drainage pipe 35 of the sampling tube body 31 away from the disinfectant mixing tank 1. The disinfectant entering the sampling tube body 31 is passed through the baffle 36 into the drainage pipe 35, and the disinfectant is discharged from the drainage pipe 35 to achieve sampling;

[0064] An air gap is left between the upper end of the baffle 36 and the top surface of the inner wall of the sampling tube body 31 , and the air gap is used to discharge the gas in the inner cavity of the sampling tube body 31 .

[0066] The silicone discs 341 are evenly and fixedly connected to the sampling tube body 31, and the edges of adjacent silicone discs 341 are in contact with each other;

[0067] The outer wall of the silicone disc 341 is provided with an arc-shaped concave surface 342 on the side away from the inner cavity of the disinfectant mixing tank 1;

[0068] The arc-shaped concave surface 342 of the circumferentially distributed silicone disc 341 is spliced ​​into a cone. The design of the arc-shaped concave surface 342 allows the silicone disc 341 to bend and deform toward the side away from the disinfectant mixing tank 1 under the action of a strong external force; negative pressure acts on the edge of the circumferentially distributed silicone disc 341, and the pressure of the disinfectant bends and deforms the silicone disc 341 toward the side away from the disinfectant mixing tank 1. After the negative pressure is canceled, the elastic force of the silicone disc 341 overcomes the pressure of the disinfectant and resets, closing the end of the sampling tube body 31.

[0070] The strip plate 51 is fixedly mounted longitudinally on the inner wall of the disinfectant mixing tank 1;

[0071] The left and right side walls of the strip plate 51 are both provided with slopes 52, and the slopes 52 extend obliquely to the outer wall of the strip plate 51 close to the inner cavity of the disinfectant mixing tank 1; the flow is disturbed by the obstruction of the strip plate 51, and the design of the slopes 52 changes the flow rate of the disinfectant flowing through and plays a disturbing role.

[0072] In some embodiments, in order to change the flow rate of the disinfectant flowing through the tapered groove 54 and the through hole 53 and improve the turbulence effect, the left and right side walls of the strip plate 51 are evenly provided with through holes 53 along the length direction;

[0073] Conical grooves 54 are formed at both ends of the through hole 53 , and the conical grooves 54 are located on the same side of the outer wall of the strip plate 51 .

[0074] In some embodiments, in order to improve the turbulence effect, a corrugated groove is provided on the end face of the strip plate 51 close to the inner cavity of the disinfectant preparation tank 1. The design of the corrugated groove changes the turbulence effect of blocking the vortex disinfectant, and the flow rate of the disinfectant passing through the uneven area of ​​the corrugated groove is different.

[0075] In some embodiments, in order to achieve stirring and preparing of the disinfectant, the disinfectant preparation tank 1 includes:

[0076] The round tank 11 has an arc-shaped upper end of its inner cavity;

[0077] A feeding cylinder 13 is fixedly connected to the upper end of the outer wall of the round tank 11;

[0078] A discharge pipe 14 with a valve, which is fixedly connected to the bottom surface of the round tank 11;

[0079] The stirring structure 12 has its upper end fixedly assembled in the middle of the top surface of the round tank 11, and its lower end extends to the lower end of the inner cavity of the round tank 11. The stirring structure 12 is used to stir the raw materials in the round tank 11, the feeding barrel 13 is used for feeding, and the valve of the valved discharge pipe 14 is opened for discharging.

[0083] The round rod 122 has an upper end fixedly connected to the output end of the driving motor 121, and a lower end extending to the lower end of the inner cavity of the round tank 11;

[0084] The outer wall of the round rod 122 is evenly fixed with stirring blades 123; the driving motor 121 is connected to an external power source, and the driving motor 121 drives the round rod 122 and the stirring blades 123 to rotate.

[0085] In some embodiments, in order to prevent impurities from entering, a cover plate 7 is fastened to the upper end of the feed barrel 13, and the cover plate 7 is opened when the feed barrel 13 is feeding.

[0086] Working principle:

[0087] The connecting pipe 2 is fixedly connected to the lower end of the outer wall of the disinfectant mixing tank 1. The connecting pipe 2 fixedly connected to the disinfectant mixing tank 1 serves as a sampling channel. The negative pressure sampling tube 3 is sealed and slidably inserted into the connecting pipe 2. The negative pressure sampling tube 3 is connected to an external negative pressure device and uses negative pressure suction to extract the disinfectant to complete the sampling;

[0088] The negative pressure sampling tube 3 can be used to directly sample the periphery of the inner cavity of the disinfectant mixing tank 1, or it can be extended through the connecting tube 2 to the middle of the inner cavity of the disinfectant mixing tank 1 for sampling. Using the scale groove 4 as a reference, the negative pressure sampling tube 3 is extended to different depths of the inner cavity of the disinfectant mixing tank 1 to sample, and the data average value is obtained to obtain more accurate disinfectant concentration detection data; the stirring spoiler 5 disturbs the disinfectant vortex stirred to the periphery of the inner cavity of the disinfectant mixing tank 1, so that the concentration difference between the periphery and the middle of the inner cavity of the disinfectant mixing tank 1 is reduced, further improving the accuracy of the average value data obtained by multiple sampling.
