Description

Technical Field

[0001] This invention belongs to the field of high-pressure homogenizer technology, and more specifically, relates to an internal detection mechanism for a high-pressure homogenizer. Background Technology

[0002] A high-pressure homogenizer uses the high-speed reciprocating motion of a plunger to drive the working head to subject the material to intense shearing, impact, and cavitation, making the material more ultrafine and allowing it to be mixed more evenly and stably.

[0003] Chinese patent CN216498995U discloses a high-pressure homogenizer that is easy to clean, including a homogenizer body and a water control valve. A cleaning water pump is fixedly installed in the middle of the upper end of the homogenizer body. A water inlet is provided at the upper end of the cleaning water pump. A hexagonal water transmission pipe is fixedly installed at the lower end of the cleaning water pump. The hexagonal water transmission pipe is connected to the cleaning water pump and the water inlet. The hexagonal water transmission pipe is fixedly connected to the water control valve. A cleaning treatment conduit is fixedly installed at the lower end of the water control valve. High-pressure water sprayers are fixedly installed on the inner wall of the cleaning treatment conduit. The high-pressure water sprayers are evenly distributed from top to bottom on the inner wall of the cleaning treatment conduit.

[0004] The high-pressure homogenizer in the above scheme changes its internal structure and uses pressure and multiple high-pressure water jets to flush out high-pressure, high-speed pure water or prepared cleaning solution, which can quickly wash away residual materials on the inner wall of the homogenizer, resulting in high cleaning efficiency.

[0005] However, in the above technical solution, the high-pressure water sprayer fixed on the inner wall of the cleaning duct can only quickly clean the inner wall of the homogenizer that is set in the vertical direction. It is still necessary to remove the homogenizer valve seat and the homogenizer valve core from the homogenizer before the contact area of ​​the homogenizer valve seat and the homogenizer valve core can be cleaned. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an internal detection mechanism for a high-pressure homogenizer. It can automatically detect the microbial content and composition of the material through the setting of the homogenization effect detection unit, and can judge the cleaning status inside the high-pressure homogenizer based on the detection results. At the same time, it can quickly clean the residual material adhering to the contact points without disassembling the homogenizing valve seat and homogenizing valve core.

[0007] The present invention provides an internal detection mechanism for a high-pressure homogenizer, comprising a feed cylinder and a discharge cylinder, wherein a high-pressure pump head, a homogenization valve body, and a homogenization effect detection unit are sequentially connected between the feed cylinder and the discharge cylinder in accordance with the high-pressure homogenization process. The homogenizing valve body includes: a homogenizing valve seat, wherein at least one homogenizing liquid material flow chamber a is provided inside the homogenizing valve seat, the upper end of the material flow chamber a has a first axial opening that receives the high-pressure pump head, the upper end of the material flow chamber a also has a second axial opening that is opposite to the first axial opening, a pressure regulating shaft is slidably installed inside the second axial opening, and a homogenizing valve core is provided between the first axial opening and the pressure regulating shaft; The homogeneous valve core has two sets of inwardly recessed valve surfaces at one end facing the pressure regulating shaft, and the inwardly recessed inner step of the two sets of valve surfaces collides with the annular surface; The pressure regulating shaft has an outwardly protruding flange at one end facing the homogenizing valve core. An inner step cleaning unit is formed within this flange, recessed towards the inside of the pressure regulating shaft and aligned with the perpendicular bisector of the inner step collision surface. Each inner step cleaning unit has at least one inner inclined groove located between the flange and the pressure regulating shaft. A cleaning shaft, movable along its long axis, is slidably mounted within the inner inclined groove. The presence of microbial growth inside the homogenizer and the cleanliness of residues from the previous homogenization are determined by the microbial content and composition of the water detected by the homogenization detection unit. The cleaning shaft, which slides along the inner inclined groove, allows for direct cleaning of residues adhering to the sidewalls of the inner step collision surface without disassembling the homogenizing valve seat or valve core.

[0008] As a further improvement of the present invention, the inner step cleaning unit includes: a rotating shaft, a conical roller, and a conical spiral structure. The center of the pressure adjusting shaft has a cleaning unit mounting cavity axially connected to the inner inclined groove. The rotating shaft is fixedly installed within the cleaning unit mounting cavity. The conical roller is directly or indirectly installed at one end of the rotating shaft, enabling it to rotate. The conical spiral structure is fixedly installed on the curved surface of the conical roller and meshes with a linear rack in the cleaning shaft, allowing the cleaning shaft to move back and forth along the curved surface of the conical roller. The rotation of the conical roller drives the linear rack to slide back and forth along the spiral direction of the conical spiral structure, enabling the cleaning shaft to reciprocate in cleaning the sidewalls of the inner step collision ring.

[0009] As a further improvement of the present invention, a sealing cap is fixedly provided at the end of the cleaning shaft facing the inner step collision ring surface. The sealing cap prevents material in the material flow chamber a from entering the cleaning unit mounting cavity.

[0010] As a further improvement of the present invention, a cleaning element is provided between the sealing cover and the linear rack. This cleaning element allows for the cleaning of the sidewalls of the inner step collision ring.

[0011] As a further improvement of the present invention, the cleaning component is circumferentially disposed on the outer wall of the cleaning shaft. This can further improve the cleaning effect of the cleaning shaft.

[0012] As a further improvement of the present invention, the cleaning unit mounting cavity has a guide ramp that guides the movement direction of the cleaning shaft. This can restrict the direction of the cleaning shaft.

[0013] As a further improvement of the present invention, the homogenization effect detection unit is specifically a spectrophotometer detection device. This is to detect and determine whether there is microbial growth inside the homogenizer and whether the residue from the previous homogenization has been thoroughly cleaned.

[0014] As a further improvement of the present invention, a heat exchanger is fitted around the outer periphery of the connecting pipe between the homogenization valve body and the homogenization effect detection unit. This is to control the rapid decrease in temperature of the material within the connecting pipe as it flows through the connecting pipe fitted with the heat exchanger.

[0015] As a further improvement of the present invention, the high-pressure pump head includes: a pump head body, a first one-way valve, a second one-way valve, a plunger rod, and a material flow chamber b. The material flow chamber b is disposed inside the pump head body. The first one-way valve is disposed at the lower end of the material flow chamber b. An axially extending plunger mounting cavity is provided between the second one-way valve and the first one-way valve. The plunger rod is sealed and assembled in the plunger mounting cavity.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the homogenization effect detection unit detects the microbial content and composition of the pure water flowing out of the homogenization valve seat, and determines whether there is microbial growth inside the homogenizer and whether the residue after the previous homogenization has been cleaned up based on the detected microbial content and composition of the water.

[0017] The cleaning shaft, which can slide along the long axis of the inner inclined groove to the inner step collision ring surface, cleans the residues adhering to the side wall of the inner step collision ring surface, thereby improving its cleaning efficiency for materials with excessive viscosity.

[0018] The sealing cover can also prevent material in the material flow chamber a from entering the cleaning unit installation chamber; at the same time, the cleaning components distributed circumferentially around the cleaning shaft can clean the side walls around the inner step collision ring surface, thereby further improving the cleaning effect.

[0019] In summary, the present invention has the advantages of automatically detecting the microbial content and composition of materials, and being able to determine the cleaning status inside the high-pressure homogenizer based on the detection results, and being able to quickly clean residual materials adhering to the contact points without disassembling the homogenizer valve seat and homogenizer valve core.

Implementation

[0022] Specific Implementation Example 1: Please refer to... Figure 1-4 An internal detection mechanism for a high-pressure homogenizer includes a feed cylinder 1 and a discharge cylinder 2. The feed cylinder 1 and the discharge cylinder 2 are sequentially connected to a high-pressure pump head 3, a homogenization valve body 4, and a homogenization effect detection unit 5 according to the high-pressure homogenization process. The homogenization valve body 4 includes: a homogenization valve seat 41, wherein at least one homogenization liquid material flow chamber a411 is provided inside the homogenization valve seat 41, the upper end of the material flow chamber a411 has a first axial opening 412 that receives the high pressure pump head 3, the lower end of the material flow chamber a411 has a discharge port 414 that receives the homogenization effect detection unit 5, the upper end of the material flow chamber a411 also has a second axial opening 413 that is opposite to the first axial opening 412, a pressure adjusting shaft 42 is slidably installed inside the second axial opening 413, and a homogenization valve core 43 is provided between the first axial opening 412 and the pressure adjusting shaft 42; The homogeneous valve core 43 has two sets of inwardly recessed valve surfaces 431 at one end facing the pressure regulating shaft 42. Each of the two sets of valve surfaces 431 has an inner stepped collision ring surface 432, which is recessed towards the inside of the homogeneous valve core 43. The pressure regulating shaft 42 has an outwardly protruding flange 421 at one end facing the homogeneous valve core 43. An inner step cleaning unit 422 is formed in the flange 421. The inner step cleaning unit 422 is recessed towards the inside of the pressure regulating shaft 42 and is in the same axis as the vertical line of the inner step collision annular surface 432. The inner step cleaning unit 422 has at least one inner inclined groove 4221. The inner inclined groove 4221 is located between the flange 421 and the pressure regulating shaft 42, and a cleaning shaft 4222 that can move along its long axis is slidably installed inside the inner inclined groove 4221.

[0023] In the above scheme, on the one hand, the homogenization effect detection unit 5 detects the microbial content and composition of the pure water flowing out from the homogenization valve seat 41, and on the other hand, it determines whether there is microbial growth inside the homogenizer and whether the residue after the last homogenization has been cleaned based on the detected microbial content and composition of the water.

[0024] On the other hand, when it is detected that there are residues from the previous homogenization inside the homogenizer that have not been cleaned, the cleaning shaft 4222, which can slide along the long axis of the inner inclined groove 4221 to the inner step collision ring 432, can clean the residues adhering to the side wall of the inner step collision ring 432. Compared with the existing technology that only uses pure water and cleaning liquid to repeatedly replace the homogenizing valve core 43 for cleaning, it can effectively improve the cleaning efficiency of materials with excessive viscosity.

[0025] Preferably, the inner step cleaning unit 422 includes: a rotating shaft 4223, a conical roller 4224, a linear rack 4225, a conical spiral structure 4228, a first bevel gear 4226, and a second bevel gear 4226. The center of the pressure adjusting shaft 42 has a cleaning unit mounting cavity 423 axially connected to the inner inclined groove 4221. The second bevel gear 4226 is located at the end of the cleaning unit mounting cavity 423 away from the cleaning shaft 4222. The second bevel gear 4226 is connected to a drive source outside the pressure adjusting shaft 42. The first bevel gear 4226 meshes with the second bevel gear 4226, causing the first bevel gear... The rotating shaft 4223 in the middle of the wheel 4226 has a tendency to rotate axially. The conical roller 4224 is directly or indirectly arranged at one end of the rotating shaft 4223 away from the second bevel gear 4226, so that it has the ability to rotate. The conical spiral structure 4228 is fixedly arranged on the curved surface of the conical roller 4224. The curved surface of the conical roller 4224 is arranged parallel to the cleaning shaft 4222. The straight rack 4225 is fixedly arranged on the cleaning shaft 4222 and meshes with the conical spiral structure 4228, so that the cleaning shaft 4222 has the tendency to move back and forth along the curved surface of the conical roller 4224.

[0026] In the above solution, the second bevel gear 4226 is directly driven to rotate by an external drive source. Then, the rotation shaft 4223 and the conical roller 4224 are driven to rotate by the cooperation of the second bevel gear 4226 and the first bevel gear 4226. Then, the rotation of the conical roller 4224 drives the linear rack 4225 to slide back and forth along the helical direction of its conical helical structure 4228, so that the cleaning shaft 4222 can slide back and forth along its inclined direction. The side wall of the inner step collision ring 432 can be cleaned repeatedly without disassembling the average valve body 4, thereby further improving the overall cleaning efficiency.

[0027] On the other hand, by using the cleaning unit mounting cavity 423 and its independently installed drive device to drive the movement of the cleaning shaft 4222, the situation where the pressure regulating shaft 42 and the cleaning shaft 4222 move synchronously can be avoided.

[0028] Preferably, a sealing cap 4229 is fixedly provided at one end of the cleaning shaft 4222 that faces the inner step collision ring 432, and a cleaning element 4220 is provided between the sealing cap 4229 and the linear rack 4225, and the cleaning element 4220 is circumferentially arranged on the outer wall of the cleaning shaft 4222.

[0029] In the above scheme, the sealing cover 4229 prevents the material in the material flow chamber a411 from entering the cleaning unit installation chamber 423. At the same time, the circumferentially distributed cleaning components 4220 can clean the side walls around the inner step collision ring surface 432 to improve the cleaning effect.

[0030] Preferably, the cleaning unit mounting cavity 423 has a guide slope 4230 that guides the movement direction of the cleaning shaft 4222, and the guide slope 4230 is parallel to the curved surface of the conical roller 4224.

[0031] In the above scheme, the movement direction of the cleaning shaft 4222 is limited by the setting of the guide slope 4230, so as to prevent the cleaning shaft 4222 from deviating from the cleaning angle during the movement.

[0032] In one embodiment, the homogenization effect detection unit 5 is specifically a spectrophotometer detection device.

[0033] The above scheme uses a spectrophotometer to set up a homogenization effect detection unit 5, which simultaneously detects and determines whether there is microbial growth inside the homogenizer and whether the residue from the previous homogenization has been cleaned.

[0034] Preferably, the high-pressure pump head 3 includes: a pump head body 31, a first one-way valve 32, a second one-way valve 33, a first valve ball 35, a second valve ball 35, a plunger rod 36, and a material flow chamber b37. The pump head body 31 is provided with at least one material flow chamber 411b. The first one-way valve 32 is located at the lower end of the material flow chamber b37. The first valve ball 35 is connected to the liquid outlet of the first one-way valve 32. The second one-way valve 33 is located at the upper end of the material flow chamber b37.

An axially extending plunger mounting cavity 38 is provided between the second one-way valve 33 and the first one-way valve 32. The plunger rod 36 is sealed and assembled in the plunger mounting cavity 38.

[0035] Preferably, a heat exchanger 6 is fitted around the outer periphery of the connecting pipe between the averaging valve body 4 and the homogenization effect detection unit 5. The heat exchanger 6 has an outlet at its upper end and an inlet at its lower end.
