[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-Figure 3 The utility model provides a technical solution: a hydrogen peroxide control device for an aseptic packaging machine, the control device comprising a hydrogen peroxide sterilization pool 1 for sterilizing packaging materials, a water bath heating tank 2 for purifying contaminated hydrogen peroxide, and a circulation pump 16 arranged between the hydrogen peroxide sterilization pool 1 and the water bath heating tank 2 for circulating hydrogen peroxide.

[0029] The water bath heating tank 2 includes an outer layer 21 and an inner layer 22 suspended in the outer layer 21. The open end of the outer layer 21 and the open end of the inner layer 22 are fixedly connected. The inner layer 22 is surrounded by a heating tube 24 fixed inside the outer layer 21. A temperature controller 241 connected to the heating tube 24 is fixedly connected to the outer wall of the outer layer 21. A temperature sensor 242 electrically connected to the temperature controller 241 is fixedly installed on the inner wall of the outer layer 21.

[0030] The top cover of the inner layer 22 is connected to a pot cover 23, and the pot cover 23 is provided with a waste discharge pipe 232 connected to the interior of the inner layer 22. A reflux joint 221 is fixedly connected to the bottom of the inner layer 22. The end of the reflux joint 221 away from the inner layer 22 passes through the outer layer 21 and is connected to the inlet end of the circulation pump 16 through the manifold 17. The circulation pump 16 is fixedly installed on the outer wall of the hydrogen peroxide sterilization tank 1 and is connected to the interior of the hydrogen peroxide sterilization tank 1. An inlet end joint 231 is fixedly connected to the pot cover 23, and the hydrogen peroxide sterilization tank 1 is connected to the inlet end joint 231 through the overflow pipe 15.

[0031] When in use, when the packaging material is immersed in the hydrogen peroxide sterilization pool 1, the bacteria on its surface are removed by the hydrogen peroxide, and at the same time, the water level of the hydrogen peroxide sterilization pool 1 rises and exceeds the overflow pipe 15. The contaminated hydrogen peroxide floating on the surface then enters the inner layer 22 of the water bath heating tank 2 through the overflow pipe 15. The heating pipe 24 is controlled by the thermostat 241 to heat the hot water in the outer layer 21, and the water temperature is monitored by the temperature sensor 242. The thermostat 241 is used to control the hot water to maintain a constant temperature of 40-60 degrees. The hydrogen peroxide is heated within a safe range and indirectly heated by a heated water bath, which can ensure a uniform temperature rise and make it easier to control the heating speed. The heated hydrogen peroxide will convert the impurities contained therein into waste gas and be discharged from the waste pipe 232, so that the hydrogen peroxide can be purified. The purified hydrogen peroxide is drawn by the circulation pump 16 and flows back into the hydrogen peroxide sterilization tank 1 through the reflux joint 221 and the manifold 17, thereby maintaining the purity of the hydrogen peroxide in the hydrogen peroxide sterilization tank 1 and ensuring the continuous sterilization effect of the hydrogen peroxide sterilization tank 1.

[0032] It can be understood that there is a water adding valve 211 at the side of the outer layer 21 near the top, a drain valve 212 at the bottom of the outer layer 21, and at least three support legs 25 distributed in a circular array at the bottom of the outer layer 21; the water adding valve 211 and the drain valve 212 can be used to replenish water and drain water in the outer layer 21, and the temperature can be quickly reduced by replenishing water and draining water. At the same time, the water bath heating tank 2 is supported as a whole by the support legs 25, which makes it convenient to expose the joint at the bottom of the water bath heating tank 2 and facilitate the operation of connecting pipe fittings.

[0033] Furthermore, the open part of the hydrogen peroxide sterilization pool 1 is covered with a cover 11, and a symmetrically arranged feed port 12 and a discharge port 13 are provided on the cover 11. A reversing roller 14 whose axis is parallel to the length direction of the feed port 12 is rotatably connected at a position below the overflow port in the hydrogen peroxide sterilization pool 1, and a scraper 131 fixedly connected to the cover 11 is symmetrically arranged in the discharge port 13, and the scraper 131 is made of soft material; when sterilizing the packaging material, the end of the packaging material can be penetrated by The hydrogen peroxide enters the hydrogen peroxide sterilization tank 1 through the feed port 12, then bypasses the reversing roller 14, and is then led out from the discharge port 13, thereby facilitating the continuous pulling of the packaging material, which is beneficial to improving efficiency. At the same time, when the packaging material is led out from the discharge port 13, the flexible scraper 131 in the discharge port 13 will scrape off the hydrogen peroxide attached to the surface of the material to avoid the reduction of hydrogen peroxide and ensure the cleanliness of the packaging material. The presence of the cover 11 also blocks light, which can prevent the hydrogen peroxide from volatilizing and decomposing, and is helpful to save resources.

[0034] Example 2

[0035] Different from the embodiment 1, the hydrogen peroxide sterilization pool 1 has a water quality detector 18, the output end of the water quality detector 18 is connected to the receiving end of the external control center, and the control valve input end of the circulation pump 16 is connected to the output end of the external control center.

[0036] By setting a water quality detector 18 in the hydrogen peroxide sterilization pool 1, the degree of contamination of the hydrogen peroxide pool can be monitored in real time, and the water quality can be fed back to the external control center in real time. The control center then adjusts the rotation speed of the circulation pump 16 to adjust the circulation flow rate of the hydrogen peroxide between the hydrogen peroxide sterilization pool 1 and the water bath heating tank 2 to prevent excessive accumulation of impurities in the hydrogen peroxide sterilization pool 1 and affect the sterilization effect.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
