Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, and in particular to a homogenizer with a cooling protection structure. Background Technology

[0002] The homogenizer in the emulsification pot assembly is used in the emulsification process: it forms a stable emulsion by high-speed shearing and stirring of immiscible liquids (such as oil and water). The homogenizer operates at high speed; if a single-end mechanical seal is used, the high temperature generated by end-face friction can damage the seals, affecting the homogenizer's operation and the positive and negative pressure requirements of the emulsification pot. Therefore, a double-end mechanical seal structure with cooling is adopted. Currently, the cooling water inlet valve of the mechanical seal is manually opened before starting the homogenizer, and the inlet valve is manually closed after homogenization. For details, please refer to the mechanical seal device, cooling structure, and coolant self-circulation structure of the homogenizer disclosed in Chinese Patent Publication No. CN108253142B.

[0003] However, in this manual operation method, if the operator forgets to open the cooling water inlet valve before starting the homogenizer, the homogenizer will generate high temperatures during high-speed operation, causing damage to the seals. This will not only affect the cooling water entering the emulsification pot the next time it is used, thus affecting product quality, but may also cause cooling water to leak into the motor, resulting in damage to the motor coil, a decrease in insulation resistance, and affecting the normal operation of production.

[0004] Furthermore, if the mechanical seal is damaged during production and not detected in time, it will lead to increased foaming in the product, affecting product quality. During the discharge process, if the mechanical seal is damaged, the product may be discharged from the outlet of the mechanical seal, which will not only affect the output of the product, but also the quality of the product. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the high temperature generated by the homogenizer during high-speed operation when the cooling water inlet valve is opened, which leads to damage to the seals. Therefore, this invention proposes a homogenizer with a cooling protection structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a homogenizer with a cooling protection structure, including a homogenizer installed on an emulsifying pot, with a first pipe and a second pipe connected to the coolant inlet and coolant outlet of the homogenizer respectively.

[0008] A solenoid valve is installed on the first pipe, and a flow switch and a check valve are installed on the second pipe. The check valve is located behind the flow switch along the water flow direction.

[0009] Both the solenoid valve and the flow switch are connected to an external control unit via wires.

[0010] Furthermore, a manual valve is also installed at the front end of the first pipeline along the water flow direction of the solenoid valve, and the front end of the manual valve is connected to the water supply equipment.

[0011] Furthermore, a return water tank is connected to the rear end of the one-way valve.

[0012] Furthermore, the flow switch is detachably connected to the second pipe via a detachable structure.

[0013] Furthermore, the disassembly structure includes a connecting pipe connected to both ends of the flow switch, and a connecting sleeve is fixedly installed on the connecting pipe;

[0014] The second pipe is cut off in the middle to form two installation ends. A locking sleeve is fixedly installed on the installation end. Both the locking sleeve and the connecting sleeve have a sealing structure inside. The locking sleeve and the connecting sleeve are connected by a snap-fit ​​structure.

[0015] Furthermore, the buckle structure includes an abutment tube slidably connected to the outside of the connecting sleeve by a first spring, a plurality of positioning beads are movably inserted into the outer periphery of the connecting sleeve, and the inner side of the abutment tube has an abutment portion that abuts against the movement of the positioning beads.

[0016] The outer side of the locking sleeve has an annular groove that engages with the positioning bead.

[0017] Furthermore, the sealing structure includes a fixed seat, and a sealing valve seat is movably inserted into the end face of the fixed seat via a second spring. The sealing valve seat is inserted into and sealed with the open end of the connecting sleeve or locking sleeve, and the two sealing valve seats in the connecting sleeve and locking sleeve abut against each other.

[0018] The present invention proposes a homogenizer with a cooling protection structure, which has the following advantages: the flow of cooling water is controlled by a solenoid valve to ensure that the homogenizer starts under suitable conditions, avoiding problems caused by manual operation negligence. At the same time, the structure also includes automatic detection of the homogenizer's seals. Once a leak is detected, the flow switch will detect an overflow and issue an alarm in time, thereby protecting the equipment, reducing maintenance costs, and extending the service life of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-3 As one embodiment of this utility model, a homogenizer with a cooling protection structure is disclosed, including a homogenizer 2 installed on an emulsifying pot 1. Specifically, a first pipe 3 and a second pipe 4 are respectively connected to the coolant inlet and coolant outlet of the homogenizer 2. The specific structure and working principle of the homogenizer have been disclosed in the prior art and will not be described in detail here.

[0025] Among them, a solenoid valve 5 is installed on the first pipe 3, and a flow switch 6 and a check valve 7 are installed on the second pipe 4. The check valve 7 is located behind the flow switch 6 along the water flow direction.

[0026] Both the solenoid valve 5 and the flow switch 6 are connected to an external control unit via wires.

[0027] In some embodiments, the first pipeline 3 of this invention is further equipped with a manual valve 9 at the front end of the solenoid valve 5 along the water flow direction. The front end of the manual valve 9 is connected to the water supply equipment. When working, the manual valve 9 is first opened to keep the water circuit open so that the solenoid valve 5 can be controlled subsequently. After that, when the pipeline needs to be repaired, the entire water circuit can be shut off by closing the manual valve 9.

[0028] Of course, in order to recover the overflowing coolant, the one-way valve 7 in this embodiment is connected to a return water tank 10 at its rear end. The design of the one-way valve 7 can realize the backflow prevention of water flow.

[0029] In summary, the protective structure of this utility model, in specific operation:

[0030] During the production process of the emulsification pot group, according to the process requirements, before starting the homogenizer according to the set parameters of the homogenizer, the system opens the solenoid valve 5 to introduce cooling water. When the flow switch 6 detects that coolant is flowing out, the system will default to meeting the conditions for starting the homogenizer and start the homogenizer according to the set speed and time parameters. If the flow switch 6 does not detect liquid, the system will automatically alarm and will not start the homogenizer.

[0031] This enables automatic addition of coolant when using a homogenizer, avoiding problems such as forgetting to turn it on during manual operation, thereby improving production efficiency and product quality;

[0032] In addition, when checking whether the homogenizer seal is damaged or leaking, the emulsifying pot is not started and the solenoid valve 5 controlling the water inlet is not opened. If the homogenizer seal is not damaged or leaking, the flow switch 6 detects that no water is flowing out.

[0033] If the homogenizer seal is damaged and leaks, the material in the emulsifying pot will flow to the outlet through the mechanical seal. The flow switch 6 will detect the water flow and output a signal to the control system, thus enabling the detection and protection of the entire homogenizer's leakage status.

[0034] Furthermore, in this embodiment, the flow switch 6 is detachably connected to the second pipe 4 via the disassembly structure 8. The disassembly structure 8 is designed to facilitate the disassembly and replacement of the flow switch 6, so that when the flow switch 6 is damaged, the entire flow switch 6 can be disassembled through the disassembly structure 8.

[0035] In some embodiments, the disassembly structure 8 of the present invention includes a connecting pipe 81 connected to both ends of the flow switch 6, and a connecting sleeve 82 is fixedly installed on the connecting pipe 81.

[0036] The second pipe 4 is cut off in the middle to form two installation ends 41. A locking sleeve 83 is fixedly installed on the installation end. Both the locking sleeve 83 and the connecting sleeve 82 have a sealing structure 84 inside. The locking sleeve 83 and the connecting sleeve 82 are connected by a snap-fit ​​structure.

[0037] Based on the above embodiments, the buckle structure in this embodiment includes an abutment tube 86 slidably connected to the outside of the connecting sleeve 82 by a first spring 85. A plurality of positioning beads 87 are movably inserted into the outer periphery of the connecting sleeve 82. Specifically, a hole is opened on the outer periphery of the connecting sleeve 82, and the positioning beads 87 are placed in the hole. The diameter of the positioning beads 87 should be larger than the inner diameter of the hole to prevent the positioning beads 87 from falling out of the hole. The inner side of the abutment tube 86 has an abutment part 861 that abuts against the movement of the positioning beads 87.

[0038] The outer side of the locking sleeve 83 has an annular groove 831 that engages with the positioning bead 87.

[0039] In this embodiment, when the flow switch 6 needs to be installed, the connecting sleeve 82 and the locking sleeve 83 are first inserted, and the positioning bead 87 is moved to the annular groove 831 for locking. Then, the abutment tube 86 is moved. When the abutment part 861 on the abutment tube 86 moves to the outside of the positioning bead 87, the position of the positioning bead 87 is locked, thereby completing the quick connection. Similarly, when disassembling, simply slide the abutment tube 86 backward to release it from the restriction of the positioning bead 87. Since the positioning bead 87 can move freely at this time, the connecting sleeve 82 and the locking sleeve 83 can be separated.

[0040] Furthermore, in this utility model, the sealing structure 84 includes a fixed base 841, and a sealing valve seat 843 is movably inserted into the end face of the fixed base 841 via a second spring 842. The sealing valve seat 843 is inserted into and sealed with the open end of the connecting sleeve 82 or the locking sleeve 83. The two sealing valve seats 843 in the connecting sleeve 82 and the locking sleeve 83 abut against each other.

[0041] In other words, when the connecting sleeve 82 and the locking sleeve 83 are mated, the sealing valve seat 843 inside them abuts and moves, thus forming a passage between the connecting sleeve 82 and the locking sleeve 83, which can maintain the flow of water. In this embodiment, the fixing seat 841 is installed inside the connecting sleeve 82 and the locking sleeve 83.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
