Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide disinfection, in particular to a hydrogen peroxide delivery device. Background Art

[0002] Hydrogen peroxide is the core of the immersion and disinfection process for milk packaging materials. Hydrogen peroxide is pumped into a immersion tank, where the packaging materials continuously pass through it, becoming immersed and disinfected. During the packaging disinfection process, hydrogen peroxide continuously evaporates and is lost, making timely replenishment crucial to ensuring product quality. Traditional filling machines were originally designed to use a gear pump to replenish hydrogen peroxide from a hydrogen peroxide tank to a hydrogen peroxide tank. Due to the strong oxidizing properties of hydrogen peroxide, gear pumps often corrode, reducing pumping capacity. Once the hydrogen peroxide replenishment rate falls below the loss rate, the hydrogen peroxide tank low-level alarm goes off, halting production. The original gear pumps were imported, expensive, and took a year to restock. The losses caused by gear pump corrosion were immeasurable.

[0003] Therefore, it is necessary to improve the existing hydrogen peroxide delivery device to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a hydrogen peroxide delivery device to solve the technical problems in traditional hydrogen peroxide delivery devices, such as the gear pump is often corroded, resulting in insufficient hydrogen peroxide delivery, and the long replacement cycle affects normal production.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is:

[0006] A hydrogen peroxide delivery device comprises a liquid storage tank, a high-pressure gas source, a delivery pipe and an immersion tank, wherein a sealable liquid storage cavity is provided in the liquid storage tank, an air inlet is provided at the upper portion of the liquid storage tank, the air inlet is connected to the high-pressure gas source via an air pipe, and a valve that can control the on-off of the air pipe is provided on the air pipe; a liquid outlet pipe is also provided in the liquid storage tank, one end of the liquid outlet pipe is located at the bottom of the liquid storage cavity, and the other end of the liquid outlet pipe passes through the liquid storage tank, one end of the delivery pipe is connected to the outlet end of the liquid outlet pipe, and the other end of the delivery pipe passes into the immersion tank.

[0007] Furthermore, a liquid inlet is provided on the upper portion of the liquid storage tank, and a sealing cover is provided on the liquid inlet.

[0008] Furthermore, the valve is a solenoid valve.

[0009] Furthermore, a bottom liquid level sensor and a high liquid level sensor are provided in the soaking tank, and both the bottom liquid level sensor and the high liquid level sensor are connected to the solenoid valve. The bottom liquid level sensor is located below the high liquid level sensor. The bottom liquid level sensor can trigger the solenoid valve to open, and the high liquid level sensor can trigger the solenoid valve to close.

[0010] Furthermore, the liquid storage tank and the delivery pipe are both made of corrosion-resistant materials.

[0011] Furthermore, an annular handle is provided on the outer edge of the upper end surface of the liquid storage tank.

[0012] Furthermore, the outer periphery of the extended end of the liquid outlet pipe is tapered, and one end of the delivery pipe is sleeved on the outer periphery of the extended end of the liquid outlet pipe.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. When the present invention is used, hydrogen peroxide is filled into the liquid storage chamber of the liquid storage tank. When the soaking tank needs to be replenished with hydrogen peroxide, the valve is opened to fill the upper part of the liquid storage chamber of the liquid storage tank with high-pressure gas. The air pressure in the upper part of the liquid storage chamber presses out the hydrogen peroxide, causing the hydrogen peroxide to flow out from the lower end of the liquid outlet pipe, and then pass through the delivery pipe to the soaking tank, thereby replenishing the hydrogen peroxide in the soaking tank. Based on the above, the present invention does not require contact with parts that are easily corroded during the entire process from the liquid storage tank to the soaking tank. This solves the technical problem that the gear pump in the traditional hydrogen peroxide delivery device is often corroded, resulting in insufficient hydrogen peroxide delivery, and the long replacement cycle affects normal production.

[0015] 2. The utility model provides a liquid inlet on the upper portion of the liquid storage tank, which can facilitate the replenishment of the hydrogen peroxide raw material in the liquid storage tank, and the liquid storage cavity can be kept airtight through the sealing cover.

[0016] 3. The utility model facilitates automatic opening and closing control of the valve by configuring the valve as a solenoid valve. Through the bottom liquid level sensor and the high liquid level sensor, when the hydrogen peroxide in the soaking tank is fully replenished, the high liquid level sensor is triggered, and at the same time, the high liquid level sensor triggers the solenoid valve to close; when the hydrogen peroxide in the soaking tank is consumed to a low level, the low liquid level sensor is triggered, and at the same time, the low liquid level sensor triggers the solenoid valve to open. Based on the above, the solenoid valve can be automatically controlled according to the amount of hydrogen peroxide in the soaking tank.

[0017] 4. The liquid storage tank and delivery pipe of the utility model are made of corrosion-resistant materials, which can reduce the corrosion of the liquid storage tank and the delivery pipe and increase the service life; the annular handle is provided to facilitate the lifting and movement of the liquid storage tank; the outer periphery of the protruding end of the liquid outlet pipe is tapered, which can facilitate the soft delivery pipe to be sheathed on the end of the liquid outlet pipe.

[0025] See Figure 1 and Figure 2A hydrogen peroxide delivery device includes a liquid storage tank 1, a high-pressure gas source 2, a delivery pipe 3 and an immersion tank 4. A sealable liquid storage cavity 5 is provided in the liquid storage tank 1, and an air inlet 6 is provided at the upper part of the liquid storage tank 1. The air inlet is connected to the high-pressure gas source 2 through an air pipe 7. The air pipe 7 is provided with a valve 8 that can control the on-off of the air pipe 7; a liquid outlet pipe 9 is also provided in the liquid storage tank 1, one end of the liquid outlet pipe 9 is located at the bottom of the liquid storage cavity 5, and the other end of the liquid outlet pipe 9 passes through the liquid storage tank 1, one end of the delivery pipe 3 is connected to the outlet end of the liquid outlet pipe 9, and the other end of the delivery pipe 3 passes into the immersion tank 4.

[0026] In this embodiment, the upper portion of the liquid storage tank 1 is further provided with a liquid inlet 10, and a sealing cover 11 is provided on the liquid inlet 10. The liquid inlet 10 is provided on the upper portion of the liquid storage tank 1 to facilitate the replenishment of the hydrogen peroxide raw material in the liquid storage tank 1, and the sealing cover 11 can keep the liquid storage chamber 5 in a sealed state.

[0027] In this embodiment, valve 8 is a solenoid valve. Furthermore, a bottom liquid level sensor 12 and a high liquid level sensor 13 are provided in the soaking tank 4. Both the bottom liquid level sensor 12 and the high liquid level sensor 13 are connected to the solenoid valve. The bottom liquid level sensor 12 is located below the high liquid level sensor 13. The bottom liquid level sensor 12 can trigger the solenoid valve to open, and the high liquid level sensor 13 can trigger the solenoid valve to close. By configuring valve 8 as a solenoid valve, automatic opening and closing control of valve 8 is facilitated. When the hydrogen peroxide in the soaking tank 4 is replenished to the required level, the high liquid level sensor 13 is triggered, and the high liquid level sensor 13 simultaneously triggers the solenoid valve to close. When the hydrogen peroxide in the soaking tank 4 is depleted to a low level, the low liquid level sensor is triggered, and the low liquid level sensor simultaneously triggers the solenoid valve to open. Based on the above, the solenoid valve can be automatically controlled based on the amount of hydrogen peroxide in the soaking tank 4.

[0028] In this embodiment, the liquid storage tank 1 and the delivery pipe 3 are both made of corrosion-resistant materials. Specifically, the liquid storage tank 1 is made of stainless steel, and the delivery pipe 3 is made of rubber. This can reduce corrosion of the liquid storage tank 1 and the delivery pipe 3 and increase their service life.

[0029] In this embodiment, an annular handle 14 is provided on the outer edge of the upper end surface of the liquid storage tank 1. By providing the annular handle 14, it is convenient for the liquid storage tank 1 to be lifted and moved.

[0030] In this embodiment, the outer periphery of the extended end of the liquid outlet pipe 9 is tapered, and one end of the delivery pipe 3 is sleeved on the outer periphery of the extended end of the liquid outlet pipe 9. The outer periphery of the extended end of the liquid outlet pipe 9 is tapered, which can facilitate the soft delivery pipe 3 to be sleeved on the end of the liquid outlet pipe 9.

[0031] The specific working principle is as follows:

[0032] 1. When in use, open the sealing cover 11, fill the liquid storage chamber 5 of the liquid storage tank 1 with hydrogen peroxide, and adjust the pressure of the high-pressure gas source 2 to 0.4-0.5Mpa.

[0033] 2. When the low liquid level sensor of the soaking tank 4 is triggered, hydrogen peroxide needs to be replenished. The liquid level sensor triggers the valve 8 to open, so that the upper part of the liquid storage chamber 5 of the liquid storage tank 1 is filled with high-pressure gas. The air pressure in the upper part of the liquid storage chamber 5 presses out the hydrogen peroxide, causing the hydrogen peroxide to flow out from the lower end of the liquid outlet pipe 9, and then pass through the delivery pipe 3 to the soaking tank 4, thereby replenishing the hydrogen peroxide in the soaking tank 4.

[0034] 3. When the hydrogen peroxide in the soaking tank 4 is fully replenished, the high liquid level sensor 13 is triggered. At the same time, the high liquid level sensor 13 triggers the electromagnetic valve to close, stops filling with high-pressure gas, and slowly stops replenishing the hydrogen peroxide.

[0035] 4. Steps 2 and 3 are repeated repeatedly to realize automatic delivery of hydrogen peroxide to the soaking tank 4.

[0036] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
