Description

Technical Field

[0001] This utility model relates to the technical field of liquid product processing equipment, and in particular to a liquid product sterilization machine. Background Technology

[0002] Liquid product sterilizers are commonly used to sterilize liquid products such as milk, pharmaceuticals, and condiments. To maintain the movement of the liquid products and create a continuous sterilization process, existing technologies typically incorporate a screw pump within the sterilizer. The main pipe used to transport the liquid products is connected to the screw pump, which then drives the liquid products continuously along the main pipe towards the sterilization station, thus creating a continuous sterilization process.

[0003] However, when the flow rate of liquid products fluctuates, the main pipe in front of the screw pump inlet is prone to vibration. The vibration of the main pipe, in turn, exacerbates the flow rate fluctuation of the liquid products, creating a vicious cycle. This results in a significant decrease in the conveying efficiency of the liquid products, and in severe cases, it may even lead to the rupture of the main pipe or the failure of the screw conveyor, resulting in liquid product leakage. This necessitates stopping the liquid product sterilizer for repair work, which not only severely reduces the operating efficiency of the liquid product sterilizer but also incurs additional hardware replacement costs. Although those skilled in the art have attempted to add fixing devices to the main pipe, the results have been unsatisfactory. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem that the main pipe in front of the screw pump in the existing liquid product sterilization machine is prone to vibration, which leads to a decrease in the operating efficiency of the liquid product sterilization machine, and even causes damage to the main pipe and failure of the screw conveyor, and to provide a liquid product sterilization machine.

[0005] In a first aspect, this utility model provides a liquid product sterilization machine, including a frame, a screw pump, and a main pipe. Both the screw pump and the main pipe are connected to the frame, and the inlet of the screw pump is connected to the main pipe. A first conical section is provided between the screw pump inlet and the main pipe, the diameter of which gradually increases in the direction close to the screw pump. The two ends of the first conical section are connected to the main pipe and the screw pump inlet, respectively. At least one branch pipe is connected to the side wall of the main pipe, and the branch pipe includes a second conical section, the diameter of which gradually increases in the direction away from the main pipe. The end of the second conical section close to the main pipe is connected to the main pipe, and the end of the second conical section away from the main pipe is connected to a shock absorber.

[0006] Preferably, a stabilizing link connects the shock absorber to the frame.

[0007] Preferably, a clamp is provided at the end of the stabilizing link near the shock absorber, and the shock absorber is sleeved in the clamp.

[0008] Preferably, there are at least two stabilizing links, which are spaced apart along the length of the damping cylinder.

[0009] Preferably, the length of the stabilizing link is set along the radial direction of the shock absorber.

[0010] Preferably, at least one of the following locations is rounded: the connection between the first conical section and the main pipe, the connection between the first conical section and the screw pump inlet, the connection between the side wall of the branch pipe and the side wall of the main pipe, the connection between the second conical section and the branch pipe, and the connection between the second conical section and the shock absorber.

[0011] Preferably, the second tapered section is detachably connected to the branch pipe.

[0012] Preferably, the second tapered section is connected to the branch pipe via a union.

[0013] Preferably, the second conical section is welded to the shock absorber cylinder.

[0014] Preferably, the main pipe is detachably connected to the screw pump.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a liquid product sterilization machine. By setting a first conical section between the main pipe and the screw pump, and connecting a shock-absorbing cylinder to the side wall of the main pipe via a branch pipe and a second conical section, the abrupt change in cross-section between the main pipe and the screw pump inlet can be transformed into a slow and continuous change. The flow pulsation, pressure change, and water hammer effect of the liquid product in the main pipe are dissipated into other forms of energy, thereby fundamentally solving the problem of continuous accumulation and enhancement of fluid impact and turbulence. This can suppress the vibration of the main pipe and avoid problems such as reduced operating efficiency of the liquid product sterilization machine, damage to the main pipe, and screw conveyor failure.

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0018] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections.

[0023] Example 1 like Figures 1 to 5 As shown, a liquid product sterilizer includes a frame 1, a screw pump 2, and a main pipe 3. Both the screw pump 2 and the main pipe 3 are connected to the frame 1, and the inlet of the screw pump 2 is connected to the main pipe 3. The main pipe 3 is used to transport liquid products such as milk, medicines, and condiments. A first conical section 31 is provided between the inlet of the screw pump 2 and the main pipe 3. The diameter of the first conical section 31 gradually increases in the direction approaching the screw pump 2. The diameter of the first conical section 31 at the end approaching the main pipe 3 matches the diameter of the main pipe 3, and the diameter of the first conical section 31 at the end approaching the screw pump 2 matches the diameter of the inlet of the screw pump 2. The two ends of the first conical section 31 are connected to the main pipe 3 and the inlet of the screw pump 2, respectively. At least one branch pipe 4 is connected to the side wall of the main pipe 3. The branch pipe 4 includes a second conical section 41, the diameter of which gradually increases in the direction away from the main pipe 3. The end of the second conical section 41 approaching the main pipe 3 is connected to the main pipe 3, and the end of the second conical section 41 away from the main pipe 3 is connected to a shock absorber 5.

[0024] It is important to note that Figure 1 , Figure 2 and Figure 4 In this design, the frame 1 consists of only one upright and one crossbeam. This design partially conceals the frame 1 to facilitate observation of the relative positions of the screw pump 2, main pipe 3, and branch pipe 4, and to prevent the frame 1 from obstructing these components. This design is not intended to limit the frame 1 to only include the upright and crossbeam.

[0025] The inventors of this liquid product sterilization machine discovered that the main pipe 3 in front of the screw pump 2 inlet is prone to vibration, mainly because the diameter of the main pipe 3 is different from the inlet diameter of the screw pump 2. This causes a sudden change in the cross-section at the connection between the main pipe 3 and the screw pump 2, resulting in continuous fluid impact and turbulence at the connection. Therefore, simply strengthening the fixation of the main pipe 3 can only temporarily suppress the vibration of the main pipe 3. However, the fluid impact and turbulence will continue to accumulate and intensify, acting on the main pipe 3. This causes the main pipe 3 and its fixing structure to be subjected to alternating loads, which will gradually loosen or even break during long-term use. Therefore, to fundamentally eliminate the vibration of the main pipe 3, it is best to make the diameter of the main pipe 3 and the inlet of the screw pump 2 the same.

[0026] However, the diameter of the main pipe 3 is related to the upstream equipment, and the diameter of the screw pump 2 is determined by the manufacturer, neither of which can be easily changed; therefore, this liquid product sterilization machine adds a first conical section 31 between the main pipe 3 and the screw pump 2, thereby transforming the abrupt change in cross-section between the main pipe 3 and the screw pump 2 inlet into a slow and continuous change, which is conducive to achieving a smooth flow of liquid products and reducing the impact and turbulence generated at the connection between the main pipe 3 and the screw pump 2.

[0027] On the other hand, a shock absorber 5 is connected to one side of the main pipe 3 via a branch pipe 4. The shock absorber 5 can absorb the flow pulsation, pressure changes, and water hammer effect of the liquid product in the main pipe 3 and dissipate them into other forms of energy (depending on the specific model of the shock absorber 5, it can be gas pressure or internal energy). This fundamentally solves the problem of the continuous accumulation and enhancement of fluid impact and turbulence, thereby suppressing the vibration of the main pipe 3 and avoiding problems such as reduced operating efficiency of the liquid product sterilizer, damage to the main pipe 3, and screw conveyor failure. Furthermore, considering that the diameter of the shock absorber 5 is larger than the diameter of the main pipe 3, the shock absorber 5 and the branch pipe 4 are also connected by a tapered section, thereby suppressing fluid impact and turbulence at the connection between the shock absorber 5 and the branch pipe 4.

[0028] In the above embodiments, the screw pump 2 can be a direct adoption of existing products, including but not limited to self-priming screw pump 2, non-self-priming screw pump 2, external meshing screw pump 2, or internal meshing screw pump 2.

[0029] In the above embodiments, the shock absorber 5 (also known as a pulsating damper) can be a direct use of existing products, and the specific forms include, but are not limited to, diaphragm shock absorber 5, piston shock absorber 5, or airbag shock absorber 5.

[0030] In an optional embodiment, a stabilizing link 6 is connected between the shock absorber 5 and the frame 1. The specific structural form of the stabilizing link 6 includes, but is not limited to, a plate-like member, a rod-like member, a shaft-like member, or a profile (e.g., square steel, channel steel, or aluminum square).

[0031] Since the shock absorber 5 often has a considerable length, this embodiment chooses to connect it to the frame 1 through a stabilizing link 6, thereby forming a lateral constraint on the shock absorber 5 and preventing it from tilting or deforming under its own weight or external load.

[0032] In the above embodiment, a clamp 7 is provided at one end of the stabilizing link 6 near the shock absorber 5, and the shock absorber 5 is fitted into the clamp 7. The clamp 7 can be an existing product, including but not limited to a split clamp 7 or a flexible clamp 7.

[0033] This embodiment allows workers to easily connect the shock absorber 5 to the stabilizing link 6.

[0034] In the above embodiment, the end of the stabilizing link 6 away from the shock absorber 5 can be directly welded to the frame 1.

[0035] In the above embodiments, the number of stabilizing links 6 is at least two, and the stabilizing links 6 are distributed at intervals along the length direction of the shock absorber cylinder 5.

[0036] This embodiment can further enhance the stability of the shock absorber 5.

[0037] In the above embodiment, the length of the stabilizing link 6 is arranged radially along the damping cylinder 5.

[0038] This embodiment recommends one of the length settings for the stabilizing link 6, which can prevent the damper 5 from tilting with higher structural efficiency.

[0039] In an optional embodiment, the branch pipe 4, the second conical section 41, and the shock absorber 5 are all located above the main pipe 3.

[0040] This embodiment causes the liquid product to move upward when it enters the shock absorber 5, thereby converting some of its kinetic energy into gravitational potential energy and thus reducing the impact of the liquid product on the shock absorber 5.

[0041] In an optional embodiment, at least one of the following locations is rounded: the connection between the first tapered section 31 and the main pipe 3, the connection between the first tapered section 31 and the inlet of the screw pump 2, the connection between the side wall of the branch pipe 4 and the side wall of the main pipe 3, the connection between the second tapered section 41 and the branch pipe 4, and the connection between the second tapered section 41 and the shock absorber 5; the rounded corner includes a regular rounded corner (circular) or an elliptical corner.

[0042] This embodiment can further mitigate the abrupt changes in cross-section between the first conical section 31 and the main pipe 3, between the first conical section 31 and the inlet of the screw pump 2, between the side wall of the branch pipe 4 and the side wall of the main pipe 3, between the second conical section 41 and the branch pipe 4, and between the second conical section 41 and the shock absorber 5, thereby suppressing fluid impact and turbulence at the corresponding locations.

[0043] In an optional embodiment, the second tapered section 41 is detachably connected to the branch pipe 4. Specific forms of detachable connection include, but are not limited to, threaded connection, flange connection, tenon and mortise connection, or snap-fit ​​connection.

[0044] As the usage time increases, the shock absorber 5 may wear out or be accidentally damaged. In this embodiment, the second conical section 41 is detachably connected to the branch pipe 4. When the working efficiency of the shock absorber 5 no longer meets the design requirements, the operator can remove the second conical section 41 and the shock absorber 5 together from the branch pipe 4 to replace the new shock absorber 5.

[0045] In the above embodiment, the second tapered section 41 is connected to the branch pipe 4 via a union 8. The union 8 can be a readily available product.

[0046] This embodiment allows workers to quickly and reliably connect the second conical section 41 to the branch pipe 4.

[0047] In an optional embodiment, the second tapered section 41 is welded to the shock absorber 5.

[0048] This embodiment ensures reliable connection and sealing between the second conical section 41 and the shock absorber 5.

[0049] In an optional embodiment, the main pipe 3 is detachably connected to the screw pump 2.

[0050] This embodiment allows workers to easily separate the main pipe 3 from the screw pump 2, enabling separate maintenance of each component. Specific forms of detachable connection include, but are not limited to, threaded connections, flange connections, tenon and mortise connections, or snap-fit ​​connections.

[0051] In the above embodiment, the main pipe 3 is connected to the inlet of the screw pump 2 via a union 8. The specific location of the union 8 depends on the actual situation, including but not limited to the area between the main pipe 3 and the first conical section 31, and the area between the first conical section 31 and the inlet of the screw pump 2. As mentioned above, the union 8 can be a readily available product.

[0052] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
