Abstract
Description
Technical Field
[0001] This utility model relates to the field of nitrogen production technology, and in particular to a nitrogen production device for preserving fresh goat milk powder. Background Technology
[0002] As consumers' demands for goat milk powder quality continue to rise, preservation technology for goat milk powder has become a focus of industry attention. Nitrogen, due to its stable chemical properties, can effectively isolate oxygen and inhibit microbial growth, and is widely used in the food preservation field. In the goat milk powder production process, using nitrogen generators to fill packaging bottles with nitrogen can significantly extend the shelf life of the goat milk powder and maintain its nutritional components and flavor. Therefore, efficient nitrogen generators are crucial for the preservation of goat milk powder.
[0003] A nitrogen generator for preserving goat milk powder typically includes an air compressor, an air filtration system, a nitrogen generator, a nitrogen storage tank, and gas delivery pipelines. The air compressor compresses outside air and filters it to remove impurities, moisture, and oil contaminants, resulting in clean air. This clean air enters the nitrogen generator, where, under the action of molecular sieves, pressure swing adsorption (PSA) separates nitrogen and oxygen gases. The nitrogen is enriched and collected, and the generated nitrogen is temporarily stored in the nitrogen storage tank. It is then delivered to the goat milk powder packaging stage as needed via the gas delivery pipelines.
[0004] In the existing technology, some nitrogen generating devices can only produce nitrogen gas, but it is difficult to directly fill the goat milk powder bottles and cans with nitrogen gas at the same time. This separate operation mode not only increases the complexity of the production process, but also reduces the efficiency of filling the goat milk powder bottles and cans with nitrogen gas. Therefore, a nitrogen generating device for preserving goat milk powder freshness is proposed to solve the above problems. Utility Model Content

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a nitrogen generator for preserving fresh goat milk powder, comprising a base 1, which serves as the basic support component of the entire nitrogen generator and provides a stable installation platform for the entire device. A bracket 2 is fixedly connected to the top of the base 1, which supports and installs an inflation mechanism. An inflation mechanism is provided inside the bracket 2. Tanks a11 and b12 are fixedly connected to the top of the base 1. Both tanks a11 and b12 are provided with carbon molecular sieves inside for filtering air.

[0034] The inflation mechanism includes a placement plate 3, which is mainly used to support the goat milk powder bottles. The outside of the placement plate 3 is slidably connected to the inside of the bracket 2. A cylinder 4 is fixedly connected to the top of the base 1. The cylinder 4 provides power for the lifting and lowering of the placement plate 3. The drive end of the cylinder 4 is fixedly connected to the bottom of the placement plate 3. A diversion seat 5 is fixedly connected to the top of the bracket 2. The diversion seat 5 is used to divert nitrogen for inflation. A nitrogen outlet pipe 6 is fixedly connected to the top of the diversion seat 5. The nitrogen outlet pipe 6 is used to transport nitrogen from the can a11 to the diversion seat 5. An exhaust pipe 7 is fixedly connected to the bottom of the diversion seat 5. The exhaust pipe 7 is used to fill the goat milk powder bottles from the diversion seat 5. The inside of the diversion seat 5 is provided with a diversion chamber. A diversion plate 8 is slidably connected inside the diversion seat 5. The diversion plate 8 slides inside the diversion seat 5 under the action of the drive assembly. By changing its position in the diversion chamber, the gas diversion path is adjusted. A drive assembly is fixedly connected to the outside of the bracket 2.
[0035] The drive assembly includes an L-shaped support plate 9, which is used to fix the electric push rod 10 and provide stable support for the electric push rod 10. The external side of the L-shaped support plate 9 is fixedly connected to the outer side of the bracket 2, and the electric push rod 10 is fixedly connected inside the L-shaped support plate 9. The extension and retraction of the electric push rod 10 is controlled, which drives the diverter plate 8 to slide within the diverter seat 5, thereby realizing the control of gas diversion and improving the inflation efficiency. The drive end of the electric push rod 10 is fixedly connected to the outside of the diverter plate 8.
[0036] Reference Figure 2 and Figure 4The installation mechanism includes a fixed base 14, which is the basic support structure of the installation mechanism and is used to install the sliding plate 15, the clamping plate 16, and the elastic component. The fixed base 14 is externally fixedly connected to the outside of the tank body a11. The sliding plate 15 is slidably connected inside the fixed base 14. The sliding plate 15 can drive the clamping plate 16 to move, thereby realizing the clamping and unlocking operation of the top cover 13. The clamping plate 16 is rotatably connected to the top side inside the sliding plate 15. The function of the clamping plate 16 is to lock and unlock the top cover 13 and the tank body by locking and unlocking itself in the top cover 13. The external side of the clamping plate 16 is slidably connected to the inside of the top cover 13. The external side of the sliding plate 15 is fixedly connected to the elastic component.
[0037] The elastic component includes a connecting plate 17, which ensures that the elastic force of the spring 18 can be effectively transmitted to the slide plate 15, driving the slide plate 15 to move. The outer side of the connecting plate 17 is fixedly connected to the outer side of the slide plate 15. The bottom of the connecting plate 17 is fixedly connected to the spring 18, which provides a downward elastic force to the slide plate 15, so that the locking plate 16 can be tightly locked into the locking groove inside the top cover 13, ensuring a tight connection and good seal between the top cover 13 and the tank. The top of the spring 18 is fixedly connected to the inside of the fixing seat 14, and the outer side of the connecting plate 17 is slidably connected to the inside of the fixing seat 14.
[0038] Reference Figure 1 and Figure 2 A lower connecting pipe 19 is fixedly connected to the bottom of tank a11. The lower connecting pipe 19 is used to introduce air into the interior of tank a11 and tank b12, thereby providing raw materials for the nitrogen generation process in tank a11 and tank b12. The other end of the lower connecting pipe 19 is fixedly connected to the bottom of tank b12. An air inlet pipe 20 is fixedly connected to the interior of the lower connecting pipe 19. The air inlet pipe 20 is mainly used to introduce external air into the nitrogen generation device. The air inlet pipe 20 is used to introduce air into the interior of the lower connecting pipe 19. An upper connecting pipe 21 is fixedly connected to the interior of tank a11. The upper connecting pipe 21 is used to achieve gas communication between the two tanks at the top. The other end of the upper connecting pipe 21 is fixedly connected to the interior of tank b12. Support plates 22 are fixedly connected to the exterior of both tank a11 and tank b12. The support plates 22 are used to support and fix the upper connecting pipe 21. The exterior of the upper connecting pipe 21 is fixedly connected to the interior of the support plates 22.
[0039] Working principle: External air enters the lower connecting pipe 19 through the air inlet pipe 20, and then enters tank a11 and tank b12 through the lower connecting pipe 19. The carbon molecular sieve inside tank a11 and tank b12 filters the air to produce nitrogen. The nitrogen can be collected from tank a11 and tank b12 through the upper connecting pipe 21 into the nitrogen outlet pipe 6, and enters the distribution seat 5 through the nitrogen outlet pipe 6. The nitrogen is distributed through the distribution chamber in the distribution seat 5. When filling, the goat milk powder bottle is placed on the placement plate 3. The cylinder 4 drives the placement plate 3 to rise and fall, adjusting the position of the goat milk powder bottle. After the goat milk powder bottle is aligned with the gas outlet pipe 7, the nitrogen is filled into the goat milk powder bottle from the gas outlet pipe 7. After one goat milk powder bottle is filled, the electric push rod 10 is started. The electric push rod 10 extends and retracts, causing the distribution plate 8 to slide in the distribution seat 5, adjusting the path of the nitrogen into the bottle through the gas outlet pipe 7, and filling the other goat milk powder bottle.
[0040] When maintaining the inside of the tank, pull the connecting plate 17 upward. The connecting plate 17 drives the sliding plate 15 to move upward. The sliding plate 15 drives the locking plate 16 to slide out of the top cover 13. At the same time, the spring 18 retracts, and then the locking plate 16 can rotate. The top cover 13 can be removed from the tank a11. When installing the top cover 13, after aligning the locking plate 16 with the groove in the top cover 13, the spring 18 restores its deformation and generates elastic force. The elastic force will be transmitted to the sliding plate 15 through the connecting plate 17, so that the locking plate 16 is locked into the groove and the tank is sealed.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
