Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical seal mechanism, and specifically relates to a cooling water cooling and reflux device for mechanical seal mechanism. Background Technology

[0002] In the food processing industry, especially in milk powder production, the milk powder mixer is one of the key pieces of equipment. With the increasing scale and sophistication of modern food industry, the performance requirements for milk powder mixers are constantly rising. On the one hand, increased production efficiency necessitates long-term continuous operation of the mixer; on the other hand, strict quality control of milk powder requires the mixer to maintain high stability and hygiene during operation. The mechanical seal, as a crucial component in the milk powder mixer, prevents material leakage, ensures a stable internal pressure environment, and maintains product purity. Its performance directly affects the overall operation of the mixer and the quality of the milk powder.

[0003] Currently, the mechanical seal mechanism of milk powder mixers generally uses cooling water for cooling. However, traditional cooling systems are simple in design, often discharging cooling water directly after a single cooling cycle. This not only wastes a large amount of water resources but also increases the water costs for enterprises. For example, on large-scale milk powder production lines, multiple mixers operate continuously, resulting in a considerable total consumption of cooling water.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a cooling water cooling and reflux device for mechanical seal mechanisms to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a cooling water cooling and reflux device for a mechanical seal mechanism, comprising a rotating ring, a stationary ring sleeved on the outside of the rotating ring, a first liquid pipe and a second liquid pipe respectively connected to the stationary ring, and a conduit installed on both the first liquid pipe and the second liquid pipe, with a micro air pump connected to the middle of the conduit on the first liquid pipe, and the other ends of the two conduits connected to a connecting box, the connecting box having a heat conduction mechanism inside, a heat dissipation mechanism inside the cavity of the heat conduction mechanism, the heat dissipation mechanism being installed on the connecting box, and cooling water stirring assemblies symmetrically engaged on the heat dissipation mechanism, with both cooling water stirring assemblies being disposed in the inner cavity of the connecting box.

[0008] Furthermore, the heat conduction mechanism includes a heat conduction pipe, which is fixedly installed inside the connecting box, and multiple heat conduction plates are arranged in a circumferential array on the circumferential surface of the heat conduction pipe within the connecting box.

[0009] Furthermore, the heat dissipation mechanism includes a drive motor, a support frame is fixedly mounted on the drive motor, the support frame is fixedly mounted on the connecting box, and an output shaft is fixedly mounted on the output end of the drive motor.

[0010] Furthermore, multiple rotating fan blades are arranged in a circumferential array on the circumferential surface of the output shaft and within the cavity of the heat pipe, and a rotating gear is fixedly installed on the outer wall of the output shaft.

[0011] Furthermore, the cooling water stirring assembly includes a rotating shaft, which is rotatably mounted on the connecting box. A fixed gear is fixedly mounted on one end of the rotating shaft, and the fixed gear meshes with the rotating gear.

[0012] Furthermore, the rotating shaft passes through the connecting box and extends into its interior, and multiple connecting blocks are fixedly installed on the circumferential surface of the rotating shaft and inside the connecting box.

[0013] Furthermore, the connecting block has a circumferential array of multiple stirring rods arranged in an L-shape on its circumferential surface.

[0014] This utility model has the following beneficial effects:

[0015] 1. During operation, the heat dissipation mechanism of this utility model drives the cooling water stirring component that meshes symmetrically with it. The cooling water stirring component stirs the returning cooling water in the inner cavity of the connecting box. The stirring action makes the cooling water more evenly distributed in the connecting box, ensuring that each part of the cooling water can fully contact the heat conduction mechanism, improving the heat transfer efficiency, so that it can be transported again between the stationary ring and the moving ring for the next round of cooling cycle. This cycle is repeated, realizing the multiple use of cooling water, effectively reducing the waste of water resources, and at the same time providing efficient cooling guarantee for the mechanical seal of the milk powder mixer, meeting the needs of long-term continuous operation of the milk powder mixer and strict control of product quality.

[0016] 2. In this utility model, the heat dissipation mechanism in the inner cavity of the heat conduction mechanism starts to rotate. Then, the heat dissipation mechanism generates airflow through its own rotation. When it rotates, the surrounding air is driven to form a directional wind. The heat of the heat conduction mechanism is quickly dissipated into the surrounding environment, reducing its own temperature.

[0017] 3. When the micro air pump of this utility model is started, it generates suction in the conduit of the first liquid pipe, drawing the cooling water in the first liquid pipe into the connecting box. The cooling water in the connecting box is pushed, causing it to enter the sealing area between the stationary ring and the moving ring through the conduit of the second liquid pipe. The cooling water absorbs the heat generated by the friction between the moving ring and the stationary ring in this area, thereby cooling the sealing area and preventing mechanical seal failure due to overheating and possible material leakage.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a cooling water cooling and reflux device for a mechanical seal mechanism, including a moving ring 1, a stationary ring 2 sleeved on the outside of the moving ring 1, a first liquid pipe 3 and a second liquid pipe 4 respectively connected to the stationary ring 2, and a conduit 5 installed on both the first liquid pipe 3 and the second liquid pipe 4. A micro air pump 10 is connected to the middle of the conduit 5 on the first liquid pipe 3, and the other ends of the two conduits 5 are connected to a connecting box 6. A heat conduction mechanism 7 is provided inside the connecting box 6, and a heat dissipation mechanism 8 is provided in the cavity of the heat conduction mechanism 7. The heat dissipation mechanism 8 is installed on the connecting box 6, and cooling water stirring components 9 are symmetrically engaged on the heat dissipation mechanism 8. Both cooling water stirring components 9 are arranged in the inner cavity of the connecting box 6.

[0032] The moving ring 1 and the stationary ring 2 are usually installed at the sealing connection between the stirring shaft and the machine body of the milk powder mixer. The moving ring 1 is tightly fitted with the stirring shaft and rotates with the shaft, while the stationary ring 2 is fixed on the machine body. The two fit together to form a sealing surface to prevent milk powder material leakage. The micro air pump 10 and the connecting box 6 are both installed outside the machine body.

[0033] First, the micro air pump 10 starts, generating suction in the conduit 5 of the first liquid pipe 3, drawing the cooling water in the first liquid pipe 3 into the connecting box 6. The cooling water in the connecting box 6 is pushed, causing it to enter the sealing area between the stationary ring 2 and the moving ring 1 through the conduit 5 of the second liquid pipe 4. In this area, the cooling water absorbs the heat generated by the friction between the moving ring 1 and the stationary ring 2, thereby cooling the sealing area and preventing mechanical seal failure due to overheating and potential material leakage. After absorbing heat, the cooling water is drawn back into the connecting box 6 through the first liquid pipe 3 and the conduit 5 of the first liquid pipe 3 under the continuous action of the micro air pump 10. After entering the connecting box 6, the heat conduction mechanism 7 begins to function, using its excellent thermal conductivity to quickly transfer the heat in the cooling water to the heat conduction mechanism 7. Simultaneously, the heat dissipation mechanism 8 inside the heat conduction mechanism 7 is activated and rotates. The heat dissipation mechanism 8 generates airflow through its rotation, creating a directional airflow that rapidly dissipates heat from the heat conduction mechanism 7 into the surrounding environment, lowering its own temperature. During operation, the heat dissipation mechanism 8 drives the symmetrically meshing cooling water stirring assembly 9. This assembly stirs the returning cooling water within the connecting box 6, ensuring a more even distribution of the cooling water and guaranteeing that all parts of the cooling water fully contact the heat conduction mechanism 7, improving heat transfer efficiency. This allows the water to be transported again between the stationary ring 2 and the moving ring 1 for the next cooling cycle. This continuous cycle enables multiple uses of the cooling water, effectively reducing water waste and providing a stable and efficient cooling guarantee for the mechanical seal of the milk powder mixer, meeting the requirements of long-term continuous operation and strict product quality control.

[0034] In one embodiment, the heat conduction mechanism 7 includes a heat conduction pipe 701, which is fixedly installed inside the connecting box 6. Multiple heat conduction plates 702 are arranged in a circumferential array on the circumferential surface of the heat conduction pipe 701 and located inside the connecting box 6.

[0035] The heat dissipation mechanism 8 includes a drive motor 801, a support frame 802 is fixedly mounted on the drive motor 801, the support frame 802 is fixedly mounted on the connecting box 6, and an output shaft 803 is fixedly mounted on the output end of the drive motor 801.

[0036] Multiple rotating fan blades 804 are arranged in a circumferential array on the circumferential surface of the output shaft 803 and within the cavity of the heat pipe 701. A rotating gear 805 is fixedly installed on the outer wall of the output shaft 803.

[0037] After the cooling water absorbs heat from the sealed area between the stationary ring 2 and the moving ring 1 and flows back to the connecting box 6 through the conduit 5, the heat is first absorbed by the heat-conducting pipe 701. Due to its excellent thermal conductivity, the heat-conducting pipe 701 can quickly conduct heat within itself. The multiple heat-conducting fins 702 distributed on the circumference of the heat-conducting pipe 701 further increase the contact area with the cooling water, allowing heat to be transferred more efficiently from the cooling water to the heat-conducting pipe 701 and its heat-conducting fins 702, accelerating the heat collection process. Simultaneously, the drive motor 801 starts, driving the output shaft 803 to rotate, located on the heat-conducting pipe 701. Multiple rotating fan blades 804 inside the cavity rotate together with the output shaft 803. The rotation of the rotating fan blades 804 causes the air inside the heat pipe 701 cavity to flow rapidly. This flowing air continuously carries away the heat from the rotating fan blades 804 and the inner wall of the heat pipe 701, transferring the heat to the environment outside the connecting box 6, thus achieving the heat dissipation function and reducing the temperature of the heat pipe 701. This ensures that the heat pipe 701 and multiple heat-conducting plates 702 can continuously and effectively absorb heat from the cooling water. In addition, the rotating gear 805 fixed on the outer wall of the output shaft 803 also rotates with the output shaft 803.

[0038] In one embodiment, the cooling water stirring assembly 9 includes a rotating shaft 901, which is rotatably mounted on the connecting box 6. A fixed gear 902 is fixedly mounted on one end of the rotating shaft 901, and the fixed gear 902 meshes with the rotating gear 805.

[0039] The rotating shaft 901 passes through the connecting box 6 and extends into it. Multiple connecting blocks 903 are fixedly installed on the circumferential surface of the rotating shaft 901 and inside the connecting box 6.

[0040] The connecting block 903 has a circumferential array of multiple stirring rods 904, which are arranged in an L-shape.

[0041] When the drive motor 801 starts, the output shaft 803 drives the rotating gear 805 to rotate, and the fixed gear 902 meshing with it begins to rotate. Since the fixed gear 902 is mounted on the rotating shaft 901, the rotating shaft 901 also rotates on the connecting box 6. During the rotation of the rotating shaft 901, the connecting block 903 located inside the connecting box 6 on its circumference and the L-shaped stirring rod 904 on the connecting block 903 move in a circular motion together. The L-shaped design of the stirring rod 904 can exert a force on the cooling water inside the connecting box 6 during rotation, causing it to form a... The circulating flow promotes the mixing of cooling water in different areas, resulting in a more uniform temperature distribution. This allows the cooling water, which has been initially cooled by the heat pipe 701 and multiple heat-conducting plates 702, to fully exchange heat with the higher-temperature cooling water, improving the overall heat dissipation efficiency. In this way, the cooled water is in a lower and more uniform temperature state before being transported by the micro air pump 10 between the moving ring 1 and the stationary ring 2 for sealing and cooling. This provides a stable and continuous cooling guarantee for the mechanical seal of the milk powder mixer, ensuring the reliability of the mechanical seal during long-term operation of the milk powder mixer.
