Description

Technical Field

[0001] This utility model relates to the technical field of plate sterilizer components, specifically a flow rate regulating mechanism for a plate sterilizer. Background Technology

[0002] Plate sterilizers can be used in aseptic heat treatment systems for liquid beverages and foods. Utilizing high-precision product / water temperature difference control, the product is fed into the heat exchanger from the balance tank. After exchanging heat with the sterilized hot material in the heating section, the temperature of the cold material is raised to a predetermined value. Then, it is indirectly heated to 120°C by water heated by steam. The material is maintained at the required temperature for a period of time in the holding tube for ultra-high temperature sterilization. After exiting the holding tube, it exchanges heat with the cold material entering the machine. Finally, it is cooled to the predetermined outlet temperature in the cooling section. The entire process is carried out in a closed state to ensure the biological stability of the material.

[0003] Chinese Utility Model Patent Publication No. CN217826630U discloses a flow rate regulating mechanism for a plate sterilizer. The specification of this mechanism states that by adding a temperature sensor, an MCU, and a drive motor to the original structure, the temperature sensor's probe is located inside the cylinder, allowing real-time acquisition of temperature data of the material flowing through the cylinder. This data is then transmitted to the MCU, which analyzes and calculates the temperature data to control the electric ball valve and drive motor accordingly. This structure allows for automated dynamic adjustment of the material flow rate based on the actual temperature of the material in the plate sterilizer's internal circulation pipeline, reducing the workload of manual operation and improving the flow rate adjustment efficiency. However, this flow rate regulating mechanism lacks a detachable structure with guide vanes, making cleaning and maintenance difficult. Furthermore, the single set of guide vanes results in low flow rate regulation efficiency and poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a flow rate regulating mechanism for a plate sterilizer, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a flow rate regulating mechanism for a plate sterilizer, including a base frame and a top frame. A cylinder and an electric ball valve are provided at the end of the top frame away from the base frame. An inlet is provided at the end of the cylinder away from the top frame. A temperature sensor is provided on the top of the cylinder away from the inlet. An outlet is provided at the end of the cylinder near the electric ball valve. A motor is fixedly installed at the center of the end of the cylinder away from the electric ball valve. A transmission assembly is provided on the output shaft of the motor. An impeller assembly is provided on the outside of the transmission assembly.

[0006] Preferably, a control unit is fixedly installed between the base frame and the top frame, a plate heat exchanger and a sterilization tank are fixedly installed at one end of the base frame near the top frame, an mounting plate is provided on the side of the cylinder near the top frame, and an mounting base is fixedly installed at one end of the cylinder near the mounting plate.

[0007] The above technical solution improves the overall stability of the device by setting up a base frame and a top frame, facilitates the start-up and shutdown of the device by setting up a control unit, and enables temperature control of milk by using a plate heat exchanger.

[0008] Preferably, the outer ends of both the inlet and outlet are fixedly connected to flanges.

[0009] The above technical solution involves fixing flanges to the outer ends of both the inlet and outlet, facilitating quick connection and disassembly with external pipelines. Furthermore, the flange connection provides excellent sealing, effectively preventing leakage during milk transportation and ensuring the stability of the milk transportation environment.

[0011] The above technical solution includes a transmission component that is fixedly connected to the output shaft of the motor via a rotating rod, which facilitates precise rotation of the rotating rod and thus causes the impeller assembly to rotate.

[0012] Preferably, the impeller assembly includes a mounting sleeve, on the outer surface of which blades are annularly mounted, and on the inner surface of which a positioning block is annularly mounted. A locking bolt is provided at the end of the mounting sleeve away from the transmission assembly, and a threaded hole is provided at the end of the mounting sleeve near the locking bolt.

[0013] The above technical solution incorporates an impeller assembly, which facilitates quick installation with the transmission assembly. Furthermore, the engagement of the locking bolts and screw holes further enhances the stability of the impeller assembly during rotation.

[0014] Preferably, the cross-section of the mounting sleeve is the same as that of the rotating rod, the positioning block and the groove are slidably connected, and the locking bolt passes through the screw hole and is threadedly connected to the limiting hole.

[0015] Through the above technical solution, by using the same cross-section of the mounting sleeve and the rotating rod, and the sliding connection between the positioning block and the groove, a quick connection between the mounting sleeve and the rotating rod can be achieved. Furthermore, the threaded connection between the locking bolt and the limiting hole further enhances the stability of the connection between the impeller assembly and the transmission assembly, ensuring that the impeller assembly will not fall off during operation. In addition, the threaded connection between the locking bolt and the limiting hole also facilitates the quick disassembly of the impeller assembly and the transmission assembly, making subsequent maintenance easier and improving disassembly and assembly efficiency.

[0016] Preferably, the impeller assembly is provided in two identical sets, and both sets of the impeller assembly are located on the outer surface of the rotor.

[0017] By using the above technical solution, and by setting two sets of identical impeller assemblies, the flow rate regulation efficiency can be effectively increased.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-8 As shown, the present invention provides a flow rate regulating mechanism for a plate sterilizer, including a base frame 1 and a top frame 3. A cylinder 7 and an electric ball valve 8 are provided at the end of the top frame 3 away from the base frame 1. An inlet 10 is provided at the end of the cylinder 7 away from the top frame 3. A temperature sensor 11 is provided on the top of the cylinder 7 away from the inlet 10. An outlet 12 is provided at the end of the cylinder 7 near the electric ball valve 8. A motor 13 is fixedly installed at the center of the end of the cylinder 7 away from the electric ball valve 8. A transmission assembly 14 is provided on the output shaft of the motor 13. An impeller assembly 15 is provided on the outside of the transmission assembly 14.

[0023] Specifically, a control unit 2 is fixedly installed between the base frame 1 and the top frame 3. A plate heat exchanger 4 and a sterilization tank 5 are fixedly installed at the end of the base frame 1 near the top frame 3. A mounting plate 6 is provided on the side of the cylinder 7 near the top frame 3, and a mounting base 9 is fixedly installed at the end of the cylinder 7 near the mounting plate 6. The advantages are that the base frame 1 and top frame 3 improve the overall stability of the device; the control unit 2 facilitates the operator's control of the device's start-up and shutdown; and the plate heat exchanger 4 enables temperature control of the milk.

[0024] Specifically, flanges are fixedly connected to the outer ends of both the inlet 10 and the outlet 12. The advantage is that by fixing flanges to the outer ends of both the inlet 10 and the outlet 12, it is easy to quickly connect and disconnect from external pipelines. Furthermore, the flange connection provides good sealing, effectively preventing leakage during milk transportation and ensuring the stability of the milk transportation environment.

[0025] Specifically, the transmission assembly 14 includes a rotating rod 1401. A groove 1402 is annularly formed on the outer surface of the rotating rod 1401. A limiting hole 1403 is formed on the side of the outer surface of the rotating rod 1401 away from the groove 1402. A threaded portion 1404 is provided at the end of the rotating rod 1401 away from the motor 13, and a fixing cap 1405, threaded to the threaded portion 1404, is provided on the side of the rotating rod 1401 away from the motor 13. The advantage is that by providing the transmission assembly 14 and fixing the rotating rod 1401 to the output shaft of the motor 13, the rotating rod 1401 can be rotated precisely, thereby causing the impeller assembly 15 to rotate.

[0026] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, the impeller assembly 15 includes a mounting sleeve 1501. Blades 1502 are annularly mounted on the outer surface of the mounting sleeve 1501, and a positioning block 1503 is annularly mounted on the inner surface of the mounting sleeve 1501. A locking bolt 1504 is provided at the end of the mounting sleeve 1501 away from the transmission assembly 14, and a threaded hole 1505 is provided at the end of the mounting sleeve 1501 near the locking bolt 1504. The advantage is that the impeller assembly 15 facilitates quick installation with the transmission assembly 14, and the cooperation between the locking bolt 1504 and the threaded hole 1505 further improves the stability of the impeller assembly 15 during rotation.

[0028] Specifically, the cross-section of the mounting sleeve 1501 is the same as that of the rotating rod 1401. The positioning block 1503 and the groove 1402 are slidably connected, and the locking bolt 1504 passes through the screw hole 1505 and is threadedly connected to the limiting hole 1403. The advantages are that by having the mounting sleeve 1501 and the rotating rod 1401 have the same cross-section, and by having the positioning block 1503 and the groove 1402 slidably connected, a quick connection between the mounting sleeve 1501 and the rotating rod 1401 can be achieved. Furthermore, the threaded connection between the locking bolt 1504 and the screw hole 1505 and the limiting hole 1403 further enhances the stability of the connection between the impeller assembly 15 and the transmission assembly 14, ensuring that the impeller assembly 15 will not fall off during operation. Additionally, the threaded connection between the locking bolt 1504 and the limiting hole 1403 facilitates quick disassembly of the impeller assembly 15 and the transmission assembly 14, simplifying future maintenance and improving assembly and disassembly efficiency.

[0029] Specifically, the impeller assembly 15 has two identical sets, both located on the outer surface of the rotor 1401. The advantage is that by using two identical sets of impeller assemblies 15, the flow rate regulation efficiency can be effectively increased. Compared to a single set of impeller assemblies 15, it is more effective when a greater flow rate is required, thus improving transport efficiency.

[0030] Working Principle: During use, the milk transport pipeline is fixedly connected to the inlet 10 via a flange, and the outlet 12 is fixedly connected to the electric ball valve 8 via a flange. The flange connection has good sealing performance, effectively preventing leakage during milk transportation and ensuring the stability of the milk transportation environment. Since the cross-section of the mounting sleeve 1501 is the same as that of the rotating rod 1401, and the positioning block 1503 and the groove 1402 are slidably connected, a quick connection between the mounting sleeve 1501 and the rotating rod 1401 can be achieved. Furthermore, the annularly distributed grooves 1402 and the positioning block 1503 ensure the accuracy of the impeller assembly 15's transmission. Subsequently, the locking bolt 1504 passes through the threaded hole 1505 and is threadedly connected to the limiting hole 1403, further enhancing the stability of the connection between the impeller assembly 15 and the transmission assembly 14, ensuring that the impeller assembly 15 will not fall off during operation. The threaded connection design of the locking bolt 1504 and the limiting hole 1403 also facilitates the connection of the impeller assembly... The impeller assembly 15 and transmission component 14 can be quickly disassembled, facilitating later maintenance and improving disassembly and assembly efficiency. By setting two identical impeller assemblies 15, the flow rate regulation efficiency can be effectively increased. Compared with a single impeller assembly 15, it is more effective when a greater flow rate is needed, thus improving transportation efficiency. When the temperature sensor 11 detects that the milk temperature is too low, the motor 13 will drive the impeller assembly 15 to rotate at high speed, and the electric ball valve 8 will be adjusted to the fully open state. At this time, the flow rate in the cylinder 7 is at its maximum. When the temperature sensor 11 detects that the milk temperature is within the normal range, the motor 13 will drive the impeller assembly 15 to rotate at medium speed, and the electric ball valve 8 will be adjusted to the half-open state. At this time, the flow rate in the cylinder 7 is moderate. When the temperature sensor 11 detects that the milk temperature is too high, the motor 13 will drive the impeller assembly 15 to rotate at low speed, and the electric ball valve 8 will be adjusted to the slightly open state. At this time, the flow rate in the cylinder 7 is low, thereby dynamically adjusting the heat exchange rate between the milk and the plate heat exchanger 4 according to the milk temperature.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
