Description

Technical Field

[0002] Homogenizer is an important equipment in the fields of biotechnology, medicine, food industry, veterinary drug residue detection, pharmaceutical industry, cosmetics industry, paint industry and petrochemical industry. The main function of homogenizer is to make the material pass through a very narrow gap or small hole under high pressure, so as to achieve homogenization and refinement of the material. This treatment method can effectively break the particles and cell structures in the material, making it smaller and more uniform. The homogenizer valve is an important part of the internal parts of the homogenizer. The homogenizer will input the material into the homogenizer under high pressure, and the material will be homogenized through the gap between the valve core and the valve body and the impact surface. Refinement and homogenization, and then flow out from the output end of the homogenizer valve. The homogenizer valves currently on the market are mainly one-way input structures. They enter the impact surface through the gap between the valve core and the valve body, and then flow out from the output end of the homogenizer valve through the discharge channel to complete refinement and homogenization, so that the material reaches a nanometer particle size. This homogenizer valve has an unstable flow rate when the pressure is too high. In the process of the material entering the gap between the valve core and the valve body from the input end, it will reach ultra-high pressure. Due to the excessive material flow rate, it will lead to insufficient homogenization. In this environment, the homogenizer valve has an unstable flow rate due to excessive internal pressure, which is easy to cause the valve seat to crack and collapse, with a short service life and low efficiency. If a homogenizer valve with a simple structure, stable performance, bidirectional homogenization of materials, and synchronous circulation cooling through a cooling system can be designed, the above problems can be solved.

It can be seen that the two groups of valve cores 3 are respectively arranged at the two ends of the cooling core 2, and the high-speed materials flowing in from the two ends collide with each other in the impact cavity 7 between the two groups of valve cores 3 to achieve material refinement and homogenization. The refined and homogenized materials flow into the discharge channel 5 through the deflection channel 6 at the lower end of the cooling core 2, and then flow out through the discharge port 8. The structure is simple, the homogenization is more sufficient, and the two-way feeding efficiency is higher.

[0017] like Figure 3 , Figure 6 as well as Figure 8 As shown, in this embodiment, the diamond valve seat 32 is arranged at the inner end of the valve core body 31, the connection end of the high-pressure feed rod 33 is connected to the outer end of the valve core body 31 and matched with the diamond valve seat 32, the high-pressure feed rod 33 is provided with a feed channel 34, and the diamond valve seat 32 is provided with an impact channel 35, and the impact channel 35 is matched with the feed channel 34. It can be seen that the material flows from the feed channel 34 into the impact channel 35, and then flows into the impact chamber 7 through the impact channel 35 for impact homogenization.

[0018] like Figure 3 and Figure 5As shown, in this embodiment, a cooling groove 9 is further provided in the middle of the outer edge of the cooling core 2, and a cooling water inlet 10 and a cooling water outlet 11 are respectively provided at both ends of the cooling core 2, and the cooling groove 9 is respectively connected and conducted with the cooling water inlet 10 and the cooling water outlet 11, and a heat dissipation jacket 12 is provided between the cooling groove 9 and the impact buffer channel 4, and the cooling groove 9 cooperates with the impact buffer channel 4. It can be seen that the cooling groove 9 is arranged on the outside of the cooling core 2, and the cooling water enters from the cooling water inlet 10 at the lower end of the cooling core 2, so that the coolant is immersed in the inside of the cooling groove 9, and then circulated and discharged through the cooling water outlet 11, and the heat dissipation jacket 12 can transfer the heat in the impact buffer channel 4 to the cooling water more efficiently, so that the temperature of the homogenized material is reduced.

[0019] like Figure 2 , Figure 3 as well as Fig.10 As shown, in this embodiment, an impact feed channel 13 is provided in the middle of the impact chamber 7, and a plurality of impact discharge holes 14 are provided on the outer edge of the impact chamber 7. The plurality of impact discharge holes 14 are connected with the impact feed channel 13. The impact feed channel 13 is respectively matched with the diamond valve seats 32 on both sides of the impact chamber 7, and the plurality of impact discharge holes 14 are matched with the impact buffer channel 4. A limited sealing layer 15 is also provided on the outer edge of the impact chamber 7, and the two sides of the limited sealing layer 15 are respectively matched with the connection ends of the two valve core bodies 31. It can be seen that the high-speed materials at both ends are respectively injected into the impact feed channel 13 from both sides of the impact chamber 7 for impact, and the materials that have completed the impact flow into the impact buffer channel 4 with the plurality of discharge holes 14, and the plurality of discharge holes 14 are evenly distributed on the outer edge of the impact chamber 7, so that the flow rate of the outflowing materials is more stable, and the limited sealing layer 15 makes the connection between the two groups of valve core bodies 31 tighter.

[0020] like Figure 3 , Figure 6 , Figure 8 as well as Fig. 9 As shown, in this embodiment, a sealing seat 16 is further provided between the high-pressure feed rod 33 and the diamond valve seat 32, and the sealing seat 16 is set as a cone structure. The connection end of the high-pressure feed rod 33 is provided with a conical cavity 36, and the sealing seat 16 cooperates with the conical cavity 36. A sealing seat material channel 17 is provided in the middle of the sealing seat 16, and the sealing seat material channel 17 is connected with the feed channel 34 and cooperates with the diamond valve seat 32.

[0021] like Figure 3 and Figure 5 As shown, in this embodiment, a plurality of first seals 18 are provided at both ends of the outer edge of the cooling core 2, and the plurality of first seals 18 cooperate with the inner side of the valve body 1. It can be seen that the plurality of first seals 18 make the sealing between the cooling core 2 and the valve body 1 stronger, preventing the internal pressure from being too high and causing pressure relief.

[0023] like Figure 3 and Figure 6 As shown, in this embodiment, the center lines of the two groups of sealing seat material channels 17, the two groups of feed channels 34 and the two groups of impact channels 35 coincide with each other. It can be seen that the coincidence of the center lines of the two groups of sealing seat material channels 17, the two groups of feed channels 34 and the two groups of impact channels 35 can ensure that the impact contact surface between the materials at both ends is higher, and can avoid insufficient homogenization due to deviation of the material inflow direction.

[0024] like Figure 3 As shown, in this embodiment, the discharge port 8 is arranged on the side of the valve body 1 away from the deflection channel 6. It can be seen that the discharge port 8 is at the upper end and the deflection channel 6 is at the lower end, which can increase the outflow distance of the homogenized material buffer and make the outflowing material speed more stable.

[0025] like Figure 3 As shown, in this embodiment, the deflection angle of the deflection channel 6 is 60°. It can be seen that the deflection angle of 60° makes the process of the material flowing from the impact buffer channel 4 to the discharge channel 5 more stable.

[0026] The working principle of the present invention is as follows: before starting the equipment, the two groups of the high-pressure feed rods 33 are connected to the two feed ends of the homogenizer, the discharge port 8 is connected to the discharge end of the homogenizer, the cooling water inlet 10 and the cooling water outlet 11 are respectively connected to the inlet pipe and the outlet pipe, the equipment is started, the cooling water flows into the cooling water outlet 11 and fills the entire cooling tank 9, the material flows in from the feed channels 34 of the two groups of the high-pressure feed rods 33, flows into the impact feed channel 13 through the sealing seat material channel 17 and the impact channel 35, the materials flowing in from two directions collide with each other, and after the collision, the materials flow into the impact buffer channel 4 from the plurality of the impact discharge holes 14, the materials flow into the discharge channel 5 through the deflection channel 6, and then flow out through the discharge port 8, thereby realizing the cross-injection homogenization and synchronous cooling of the materials.

[0027] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
