Description

Technical Field

[0001] The invention relates to the technical field of micro jet homogenizing chambers, and more particularly to an ultra-high pressure micro jet nano material homogenizing and crushing device. Background Art

[0002] A homogenizer is a device that uses ultra-high pressure micro-jets to disperse and crush tissues in the field of biotechnology. It is widely used in fine industries such as biomedicine, food chemicals, and daily chemical care products. It can achieve nano and micro level material grades after dispersion and crushing, and the material distribution is uniform. Therefore, the dispersion and crushing structure used in the homogenizer has also become an important component that determines the uniformity of the material.

[0003] The existing utility model patent with authorization announcement number CN219482456U discloses a micro-jet homogenizing chamber and a homogenizer. The homogenizing chamber includes an outer shell, a first retaining member, a second retaining member and an interactive body. The outer shell includes a first shell and a second shell. A groove is opened on the second shell. The groove is pressed against the first shell through the second retaining member, the interactive body and the first retaining member in sequence. The upper part of the interactive body is narrow and the lower part is wide. The upper part and the groove form a third diversion channel and a fourth diversion channel. A collision channel is provided between the upper part and the lower part, and a confluence channel is provided at the lower part. The third diversion channel and the fourth diversion channel are both connected to the confluence channel through the collision channel. The first retaining member is provided with a channel, which is respectively connected to the inlet channel, the third diversion channel and the fourth diversion channel. The second retaining member is provided with a channel so that the confluence channel is connected to the outlet channel.

[0004] In the micro-jet homogenizing chamber of the above-mentioned homogenizer, a first retaining member, a second retaining member and an interactive body are arranged, and a diversion channel and a collision channel located in the middle of the interactive body are arranged on both sides of the interactive body, so that the material collides and breaks in the collision channel, and is homogenized and output under the action of ultra-high pressure to complete the collision crushing and uniform output of the material. However, the overall structure of the interactive body is to perform collision crushing in the middle collision channel, and can only perform crushing once. It is easy for the crushed particles to fail to achieve the expected uniform crushing at the nanometer or micron level, and the collision channels still need to be aligned, otherwise the material is likely to form agglomeration in the interactive body. In this regard, the present invention provides a processor for uniformly dispersing and crushing materials to improve the degree of crushing of materials. Summary of the invention

The sealing rings 91 are respectively sleeved outside the feed pipe 31 and the discharge pipe 41 to form a seal under the action of the sealing ring 91, and the support ring 92 is used to press the sealing ring 91 into the processing chamber 11 when the pre-tightening nut 1 32 locks the feed pipe 31, and to press the sealing ring 91 into the processing chamber 11 when the pre-tightening nut 2 42 locks the discharge pipe 41, so as to form a tight seal. A homogenizing chamber 12 is formed between the feed pipe 31, the discharge pipe 41 and the impact ring 2, and the crusher 5 is arranged in the homogenizing chamber 12. An impact channel 6 is formed between the crusher 5 and the feed pipe 31 and the discharge pipe 41. A confluence channel 7 connected to the impact channel 6 is formed in the crusher 5, so that when the nanomaterial of the ultra-high pressure microjet is pumped into through the feed pipe 31, the nanomaterial is impact-crushed by the impact channel 6 and the confluence channel 7, and is evenly distributed and then pumped out through the discharge pipe 41.

[0036] The crusher 5 includes a support body 51 and a protrusion 52. The protrusions 52 are respectively arranged on both sides of the support body 51. One end of the protrusion 52 on one side extends into the feed pipe 31, and one end of the protrusion 52 on the other side extends into the discharge pipe 41. The impact flow channel 6 is opened on the protrusion 52. The impact flow channel 6 on one side of the protrusion 52 is connected to the feed pipe 31, and the impact flow channel 6 on the other side of the protrusion 52 is connected to the discharge pipe 41. The impact flow channel 6 adopts two opening methods. The first opening method is to open a plurality of protrusions in a circular array along the axis of the protrusion 52, and the second opening method is to open a through hole along the axis of the protrusion 52. For the first opening method, a slow flow cavity 8 is also opened on the side of the protrusion 52 facing the support body 51, and the slow flow cavity 8 is connected to the impact flow channel 6 and the converging flow channel 7 respectively. When the nanomaterial is pumped in at high speed through the feed pipe 31 and passes through the impact channel 6, a force is formed to push the support body 51 along the axial direction of the homogenization chamber 12, pushing the support body 51 to move slightly along the axis, and after the material is extruded and crushed through the impact channel 6, it is further homogenized and crushed through the converging channel 7, and finally pumped out from the discharge pipe 41 after being extruded and crushed and homogenized through the impact channel 6 that is connected to the discharge pipe 41. In this regard, when passing through the impact channel 6 and the converging channel 7, the material will undergo multiple collisions and extrusion crushing, thereby achieving the crushing and uniform distribution of the material.

[0037] The converging flow channel 7 is opened in the support body 51, and the converging flow channel 7 includes a rectifying section 71, a diverting section 72 and a flow section 73. The rectifying section 71 is opened along the radial direction of the support body 51, and the flow section of the rectifying section 71 is rectangular, and the flow section of the slow flow chamber 8 is circular. The opening length of the rectifying section 71 is greater than the diameter of the slow flow chamber 8, so that when the material enters the rectifying section 71 through the slow flow chamber 8 during homogenization and crushing, a homogenous diversion is formed in the rectifying section 71, so that the material completely fills the rectifying section 71, and the diverting section 72 is connected with the rectifying section 71 and opened perpendicular to the rectifying section 71. A plurality of diverting sections 72 are arranged in an array along the length direction of the rectifying section 71, and are symmetrically arranged along both sides of the rectifying section 71, and the opening depth of the diverting section 72 is less than the opening depth of the rectifying section 71, so that after the material fills the rectifying section 71, it is diverted through the diverting section 72 The compression, the end of the diverter section 72 away from the rectifying section 71 is connected to the through-flow section 73, the through-flow section 73 is opened along the axial direction of the support body 51, and the support body 51 is also provided with a confluence groove 74 for connecting the through-flow section 73 and the diverter section 72. The confluence groove 74 is arranged in parallel with the rectifying section 71, and the opening depth of the through-flow section 73 is the same as the opening depth of the confluence groove 74, so that after the diversion and crushing of the diverter section 72, the flow enters the confluence groove 74 for homogeneous confluence, and after confluence, it passes through the through-flow section 73 into the confluence groove 74 on the side of the support body 51 facing the discharge pipe 41, and after filling the confluence groove 74, it enters the rectifying section 71 after further homogenization and crushing by the diverter section 72, and is homogenously pumped out from the impact flow channel 6 on the protrusion 52 on the side facing the discharge pipe 41, thereby realizing multiple homogenization and crushing of the material in the support body 51, thereby improving the efficiency of homogenizing and crushing the material.

[0038] The crusher 5 and the impact ring 2 are both made of polycrystalline diamond, so that they can remain unchanged in an ultra-high pressure working environment, thereby maintaining the structural stability of the impact channel 6 and the converging channel 7, thereby achieving the effect of stable crushing of the material.

[0039] A shell 10 is also provided outside the valve body 1 , and a liquid inlet 101 and a liquid outlet 102 are connected to the shell 10 . The liquid inlet 101 and the liquid outlet 102 are used to provide cooling liquid. The feed pipe 31 and the discharge pipe 41 extend from the shell 10 and are located in the shell 10 .

[0040] By arranging the impact ring 2 in the processing chamber 11, the feeding mechanism 3 and the discharging mechanism 4 in the jet structure form a homogenizing chamber 12 with the impact ring 2 after installation, so that when the crusher 5 is installed in the homogenizing chamber 12, an impact channel 6 is formed between the crusher 5 and the feeding mechanism 3 and the discharging mechanism 4, and a confluence channel 7 connected to the impact channel 6 is opened on the crusher 5, so that when the nanomaterial is pumped in, the nanomaterial passes through the impact channel 6 and the confluence channel 7 to achieve ultra-high pressure impact crushing, and enters the discharging mechanism 4 through the impact channel 6 and the confluence channel 7 to be uniformly pumped out. When the material is pumped in, it can be smoothly crushed through the converging flow channel 7 and the impact flow channel 6. Due to the structural setting of the impact flow channel 6 and the crusher 5, the material will undergo multiple collisions, extrusions and crushing during the period from pumping in to pumping out, so as to achieve uniform distribution of the crushed material, and can be smoothly pumped out along the discharging mechanism 4 through the converging flow channel 7 and the impact flow channel 6, thereby realizing multiple collisions and crushing of the material, improving the degree of material crushing and preventing it from being united in the processor.

[0041] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
