Description

Technical Field

[0001] This utility model relates to the technical field of energy-saving tubular UHT sterilizers, specifically an energy-saving tubular UHT sterilizer. Background Technology

[0002] Energy-saving tubular UHT sterilizers are key equipment in the food, beverage, and biopharmaceutical industries for ultra-high temperature instantaneous sterilization of materials. Their core principle is to rapidly heat materials to 135-150℃ using a tubular heat exchange structure and heat sources such as steam, holding the temperature for several seconds to kill microorganisms and spores. Simultaneously, a high-efficiency heat exchange system recovers waste heat, reducing energy consumption. This equipment, with its advantages of high sterilization efficiency, good preservation of material nutrition and flavor, and strong continuous production capacity, is widely used for the aseptic processing of fluid materials such as milk, juice, sauces, and pharmaceutical liquids. It is an important piece of equipment for ensuring product quality stability and extending shelf life. In the structure of the energy-saving tubular UHT sterilizer, the heat exchange tube is the key component for achieving the sterilization function. To adapt to the internal piping layout, adjacent heat exchange tubes are usually connected by U-shaped connectors to form a continuous material flow path. The U-shaped connectors are used to connect multiple sets of heat exchange tubes in series or parallel to form a complete material flow path.

[0003] However, existing energy-saving tubular UHT sterilizers often use flange bolts or welding to fix the U-shaped connecting pipe heads during connection, making the disassembly and assembly process between the U-shaped connecting pipe head and the heat exchange tube cumbersome. Special tools are needed to remove the bolts or cut the welding points one by one, which is not only time-consuming and labor-intensive, but also increases downtime for maintenance and affects production efficiency. In addition, when scale, blockage or damage occurs inside the heat exchange tube and it needs to be repaired separately, the limitations of the connecting pipe head make it difficult to quickly separate the target heat exchange tube from the integral pipeline connected by the U-shaped connecting pipe head, which brings great inconvenience to the maintenance work. Utility Model Content

This improves upon or solves the problem of existing energy-saving tubular UHT sterilizers where the U-shaped connecting pipe head is often fixed with flange bolts or welded, resulting in a cumbersome assembly and disassembly process. This requires the use of special tools to remove bolts or cut weld points one by one, which is not only time-consuming and labor-intensive, but also increases downtime for maintenance and affects production efficiency. Furthermore, when scaling, blockage, or damage occurs inside the heat exchange pipe, requiring separate repair, the limitations of the connecting pipe head make it difficult to quickly separate the target heat exchange pipe from the integrated pipeline formed by the U-shaped connecting pipe head, causing significant inconvenience to maintenance work.

Boxes are fixedly connected to the upper and lower sides of the right ends of several heat exchange tubes. Quick-connect devices are provided inside each box. The front and rear ends of each U-shaped connecting pipe head are movably connected to two heat exchange tubes through the quick-connect devices.

[0006] The quick-connect device includes a self-locking component and a control mechanism. There are two self-locking components, which are respectively located on the front and rear sides of the right end of the box. The control mechanism is located inside the left end of the box.

The front ends of both positioning slide rods extend out of the housing and are slidably connected to it. The lock head is located inside the housing and is fixedly connected to the rear ends of the two positioning slide rods. There are two push springs, each sleeved on the surface of one of the two positioning slide rods, with their front and rear ends respectively fixedly connected to the front surface of the inside of the housing and the front side of the lock head. The slot is formed on the rear surface of the lock head and extends through it.

[0008] As a preferred embodiment of this utility model, the upper and lower sides of both ends of the U-shaped connecting pipe head are fixedly connected with connectors, the four connectors correspond to the four boxes on the upper and lower sides of the two heat exchange tubes, and the connectors correspond to and are adapted to the slots.

[0009] As a preferred embodiment of this utility model, the control mechanism includes a pressing component and a linkage assembly. There are two pressing components, which are respectively disposed on the left side of the two lock heads, and the linkage assembly is located on the left side of the two pressing components.

[0010] In a preferred embodiment of this invention, the extrusion member includes a bending rod and an extrusion groove. The bending rod is fixedly connected to the left side surface of the lock head, and the extrusion groove is formed at the left end of the bending rod.

[0011] In a preferred embodiment of this invention, the linkage assembly includes a limiting support rod, a movable plate, a pressure rod, and a pull button.

This results in a cumbersome disassembly and assembly process between the U-shaped connecting pipe head and the heat exchange tube, requiring the use of special tools to remove bolts or cut welding points one by one. This is not only time-consuming and labor-intensive, but also increases downtime for maintenance and affects production efficiency. In addition, when scale, blockage, or damage occurs inside the heat exchange tube and requires separate repair, the limitations of the connecting pipe head make it difficult to quickly separate the target heat exchange tube from the overall pipeline formed by the U-shaped connecting pipe head, causing great inconvenience to maintenance work.

[0026] Example 1

[0027] Reference Figure 1-4This is the first embodiment of the present invention, which provides an energy-saving tubular UHT sterilizer, including a sterilizer body 1, a material tank 2, heat exchange tubes 3 and U-shaped connecting pipe heads 4. The material tank 2 is fixedly connected to the left front end of the sterilizer body 1 and is connected to the sterilizer body 1 through a pipe. There are several heat exchange tubes 3, which are evenly arranged inside the sterilizer body 1. The right ends of the heat exchange tubes 3 extend out of the sterilizer body 1 and are fixedly connected to the sterilizer body 1. There are several U-shaped connecting pipe heads 4, which are evenly arranged at the right ends of the heat exchange tubes 3. The front and rear sides of the U-shaped connecting pipe heads 4 are movably connected to two heat exchange tubes 3. The upper and lower sides of the right ends of the heat exchange tubes 3 are fixedly connected to a box 5. The box 5 is provided with a quick-connect device 6 inside. The front and rear ends of the U-shaped connecting pipe heads 4 are movably connected to two heat exchange tubes 3 through the quick-connect device 6.

[0028] The quick-connect device 6 includes a self-locking component 7 and a control mechanism 8. There are two self-locking components 7, which are respectively located on the front and rear sides of the right end of the box 5. The control mechanism 8 is located inside the left end of the box 5.

[0029] Specifically, through the coordinated action of the self-locking component 7 and the control mechanism 8 in the quick-connect device 6, the U-shaped connecting pipe head 4 and the heat exchange pipe 3 can be quickly disassembled and assembled, which greatly improves the convenience of equipment inspection and maintenance, while ensuring the sealing and stability of the connection parts.

[0030] Furthermore, the self-locking component 7 automatically locks the U-shaped connecting tube head 4 and the heat exchange tube 3 by engaging the locking head 72 with the connector 9. The control mechanism 8 drives the locking head 72 to disengage from the connector 9 through the linkage component to release the lock. The two work together to enable the U-shaped connecting tube head 4 and the heat exchange tube 3 to be easily fixed and separated.

[0031] Example 2

[0032] In the second embodiment of this utility model, the self-locking component 7 includes a positioning slide rod 71, a lock head 72, a push spring 73, and a slot 74. There are two positioning slide rods 71, both of which are located on the front side of the right end inside the box body 5. The front ends of the two positioning slide rods 71 ​​extend out of the box body 5 and are slidably connected to the box body 5. The lock head 72 is located inside the box body 5 and is fixedly connected to the rear ends of the two positioning slide rods 71. There are two push springs 73, which are respectively sleeved on the surface of the two positioning slide rods 71, and their front and rear ends are fixedly connected to the front surface inside the box body 5 and the front side of the lock head 72, respectively. The slot 74 is opened on the rear side surface of the lock head 72 and penetrates the lock head 72.

[0033] The upper and lower sides of the front and rear ends of the U-shaped connecting pipe head 4 are fixedly connected with the connectors 9. The four connectors 9 correspond to the four boxes 5 on the upper and lower sides of the two heat exchange tubes 3. The connectors 9 correspond to and are compatible with the slots 74.

[0034] Elastic sealing gaskets 10 are fitted on the left side of both the front and rear ends of the U-shaped connecting pipe head 4, and the elastic sealing gaskets 10 are fixedly connected to the U-shaped connecting pipe head 4.

[0035] Specifically, by setting the self-locking component 7, the positioning slide rod 71 guides, the push spring 73 elastically resets, and the slot 74 precisely matches the connector 9, the U-shaped connecting pipe head 4 and the heat exchange pipe 3 are automatically locked, forming a reliable seal with the elastic sealing gasket 10, which facilitates the installation and fixing for inspection and maintenance.

[0036] Furthermore, during installation, align the front and rear ends of the U-shaped connector 4 with the two heat exchange tubes 3. Simultaneously, align the connector 9 with the two locking heads 72 inside the end housing 5 of the heat exchange tube 3. Then, press and push the U-shaped connector 4 towards the heat exchange tube 3, inserting it into the right end of the heat exchange tube 3. Pressing and pushing will compress the elastic sealing gasket 10, causing it to deform and gradually fit between the mating surfaces of the U-shaped connector 4 and the heat exchange tube 3. At the same time, the front end of the connector will first contact the inclined guide surface at the right end of the two locking heads 72. As the pushing force continues to be applied, the connector... 9 will exert a squeezing force on the two locking heads 72 in the front and back directions. After the two locking heads 72 are subjected to the force, they will drive the positioning slide rod 71 to slide outward along the box body 5. At the same time, the push spring 73 sleeved on the surface of the positioning slide rod 71 will be compressed, so that the push spring 73 will further accumulate elastic potential energy. When the connector 9 moves to the slot 74 position, the two locking heads 72 will no longer be squeezed, and the elastic force of the push spring 73 will be released quickly, pushing the two locking heads 72 to reset, so that the two slots 74 are tightly engaged with the connector 9. At this time, the inner wall of the slot 74 and the outer peripheral surface of the left end of the connector 9 form a limit, realizing the automatic locking of the U-shaped connecting pipe head 4 and the heat exchange pipe 3.

[0037] The elastic sealing gaskets 10 at both ends of the U-shaped connecting pipe head 4 will be squeezed and deformed, tightly fitting between the heat exchange tube 3 and the mating surface of the U-shaped connecting pipe head 4 to form a sealing structure.

[0038] Example 3

[0039] In the third embodiment of this utility model, the control mechanism 8 includes two pressing parts 81 and a linkage component 82. The pressing parts 81 are respectively arranged on the left side of the two lock heads 72, and the linkage component 82 is on the left side of the two pressing parts 81.

[0040] The extrusion part 81 includes a bent rod 811 and an extrusion groove 812. The bent rod 811 is fixedly connected to the left side surface of the lock head 72, and the extrusion groove 812 is opened at the left end of the bent rod 811.

[0041] The linkage component 82 includes a limiting support rod 821, a movable plate 822, a pressure rod 823, and a pull button 824. There are two limiting support rods 821, which are fixedly connected to the front and rear sides of the lower left surface inside the box 5. The movable plate 822 is sleeved on the right end surface of the two limiting support rods 821 and is slidably connected to the limiting support rods 821. There are two pressure rods 823, which are fixedly connected to the front and rear sides of the upper surface of the movable plate 822. The upper ends of the two pressure rods 823 are respectively set inside the two extrusion grooves 812 and are movably connected to the extrusion grooves 812. The pull button 824 is fixedly connected to the upper surface of the movable plate 822, and its upper end extends out of the box 5 and is slidably connected to the box 5.

[0042] Specifically, by setting up a control mechanism 8, in which the linkage component 82 and the extrusion component 81 cooperate, the two locking heads 72 can be quickly linked to disengage from the connector 9 to release the lock, thereby realizing the convenient disassembly of the U-shaped connecting pipe head 4 and the heat exchange pipe 3, and greatly shortening the inspection and maintenance time.

[0043] Furthermore, during disassembly, one hand simultaneously presses the pull button 824 of the quick-connect device 6 on both the upper and lower sides and pulls it to the left. At this time, the pull button 824 will drive the moving plate 822 to slide to the left along the limiting support rod 821. Since the pressure rods 823 on the front and rear sides of the upper surface of the moving plate 822 are respectively embedded in the two extrusion grooves 812, the leftward movement of the moving plate 822 will cause the pressure rods 823 to move to the left in sync. In turn, the extrusion grooves 812 will generate a pushing force on the bending rods 811 to the front and rear sides. After the two bending rods 811 are subjected to force, they will drive the two locking heads 72 to overcome the push. The elastic force of the spring 73 moves to the front and back sides to open, while the positioning slide rod 71 slides to the outside of the box 5, which can limit the movement of the lock head 72 and ensure the stability of the movement of the lock head 72. As the two lock heads 72 move to the front and back sides to open, the two slots 74 gradually separate from the connector 9. When the pull button 824 is pulled to the limit position, the slots 74 are completely disengaged from the connector 9. At this time, the locking state between the U-shaped connecting pipe head 4 and the heat exchange tube 3 is released. Simply pull the U-shaped connecting pipe head 4 to remove it from the right end of the heat exchange tube 3 to complete the disassembly operation.

[0044] Working principle:

[0045] During disassembly, one hand simultaneously presses the pull button 824 on both the upper and lower quick-connect devices 6 and pulls it to the left. At this time, the pull button 824 will drive the moving plate 822 to slide to the left along the limiting support rod 821. Since the pressure rods 823 on the front and rear sides of the upper surface of the moving plate 822 are respectively embedded in the two extrusion grooves 812, the leftward movement of the moving plate 822 will cause the pressure rods 823 to move to the left in sync. In turn, the extrusion grooves 812 will generate a pushing force on the bending rods 811 to the front and rear sides. After the two bending rods 811 are subjected to force, they will drive the two locking heads 72 to overcome the push springs 73. The elastic force moves the lock head 72 to the front and back sides to open, while the positioning slide rod 71 slides to the outside of the box 5, which can limit the movement of the lock head 72 and ensure the stability of the movement of the lock head 72. As the two lock heads 72 move to the front and back sides to open, the two slots 74 gradually separate from the connector 9. When the pull button 824 is pulled to the limit position, the slots 74 are completely disengaged from the connector 9. At this time, the locking state between the U-shaped connecting pipe head 4 and the heat exchange tube 3 is released. You only need to pull the U-shaped connecting pipe head 4 to remove it from the right end of the heat exchange tube 3 to complete the disassembly operation.

[0046] During installation, align the front and rear ends of the U-shaped connector 4 with the two heat exchange tubes 3. Simultaneously, align the connector 9 with the two locking heads 72 inside the housing 5 at the end of the heat exchange tube 3. Then, press and push the U-shaped connector 4 towards the heat exchange tube 3, inserting it into the right end of the heat exchange tube 3. Pressing and pushing will compress the elastic sealing gasket 10, causing it to deform and gradually fit between the mating surfaces of the U-shaped connector 4 and the heat exchange tube 3. At the same time, the front end of the connector will first contact the inclined guide surface at the right end of the two locking heads 72. As the pushing force continues to be applied, the connector 9 will... The two locking heads 72 generate a squeezing force on both sides. After being subjected to the force, the two locking heads 72 drive the positioning slide rod 71 to slide outward along the box 5. At the same time, the push spring 73 sleeved on the surface of the positioning slide rod 71 is compressed, so that the push spring 73 further accumulates elastic potential energy. When the connector 9 moves to the slot 74 position, the two locking heads 72 are no longer squeezed, and the elastic force of the push spring 73 will be released quickly, pushing the two locking heads 72 to reset, so that the two slots 74 are tightly engaged with the connector 9. At this time, the inner wall of the slot 74 and the outer peripheral surface of the left end of the connector 9 form a limit, realizing the automatic locking of the U-shaped connecting pipe head 4 and the heat exchange pipe 3.

[0047] During this process, the elastic sealing gaskets 10 at both ends of the U-shaped connecting pipe head 4 will be squeezed and deformed, tightly fitting between the mating surfaces of the heat exchange tube 3 and the U-shaped connecting pipe head 4, forming a sealing structure. The elastic deformation fills the connection gap, preventing material leakage during high-pressure flow, while reducing wear on the mating surfaces during disassembly and assembly, and extending the service life of the sealing components.

[0048] In summary, by using the sterilization body 1, material tank 2, heat exchange tube 3, U-shaped connecting pipe head 4, box 5, quick-connect device 6, self-locking component 7, positioning slide rod 71, lock head 72, push spring 73, slot 74, control mechanism 8, extrusion component 81, bending rod 811, extrusion groove 812, linkage component 82, limit support rod 821, moving plate 822, pressure rod 823, pull button 824, connector 9, and elastic sealing gasket 10 in combination, the problem of using flange bolts for connecting the U-shaped connecting pipe head in existing energy-saving tubular UHT sterilizers is improved or solved to a certain extent. The traditional methods of fixing or welding U-shaped connectors to heat exchange tubes make the assembly and disassembly process cumbersome. Special tools are needed to remove each bolt or cut each weld point, which is time-consuming, labor-intensive, increases downtime for maintenance, and impacts production efficiency. Furthermore, when scale buildup, blockages, or damage occur inside the heat exchange tubes requiring individual repair, the limitations of the connector make it difficult to quickly separate the target heat exchange tube from the U-shaped connector, greatly hindering maintenance. This new solution allows for rapid assembly and disassembly of U-shaped connectors to heat exchange tubes without the need for special tools, saving time and effort.

[0049] The sterilization body 1, material tank 2, heat exchange tube 3, U-shaped connecting pipe head 4, and push spring 73 used in this application can be additionally equipped with protective measures of common knowledge in this technical field under different usage environments, including but not limited to the following methods, such as protective covers for equipment protection, dustproof nets for equipment dust prevention, and sealing components or waterproof coatings for equipment waterproofing, etc., which are commonly used by those skilled in the art.
