Description

Microporous homogeneous pump body

Technical Field

The invention relates to the technical field of high-pressure homogenizers, in particular to a homogenizing pump body with micropores, which is different from a common homogenizing valve structure homogenizer.

Background

The high-pressure homogenizer is also called as an ultra-high pressure nano homogenizer, and can make the material in suspension state flow through a containing cavity (the main flow design is a high-pressure homogenizing cavity, a collision cavity or a micro-channel cavity) with a special structure at high speed under the action of ultra-high pressure (up to 60000 psi) through a mechanical plunger or hydraulic pressure, so that the material is subjected to instant pressure loss, and the liquid flow causes a shearing effect through changing the direction, so that the material is subjected to a series of changes of physical, chemical, structural properties and the like, and finally the effects of reducing the particle size and increasing the uniformity are achieved.

The existing high-pressure homogenizer is mainly a pressure module, and the single-shaft motor drives a crankcase body and a synchronous wheel to link and drive a ceramic plunger to reciprocate. The biggest problem of single module is when the plunger reciprocating motion, when the plunger starts and moves to near the terminal point, the extrusion efficiency to the fluid in the high pressure through-hole board reduces, causes there is sine wave pulse between the high pressure, and especially at the super high pressure pulse is very big, causes the business turn over valve closing speed to change, causes high pressure homogenizer at during operation internal pressure very unstable, and the flow fluctuation is very big.

when the gap between the valve core 613 and the valve seat 612 needs to be adjusted, the handle sleeve 91 is driven to rotate by pulling the handle 92, and because the handle sleeve 91 is in threaded connection with the outer edge surface of the support sleeve 933, the handle sleeve 91 moves back and forth when rotating, so as to drive the T-shaped spring stacking rod 931 to rotate and push the T-shaped spring stacking rod 931 to move back and forth, meanwhile, one end of the T-shaped spring stacking rod 931 is inserted into the support ring 934, the spring stacking 932 is stressed and compressed, the spring stacking 932 drives the support ring 934 to rotate and push the support ring to move back and forth when rotating, the plane bearing 935 moves back and forth under the action of force, the copper cushion 936 moves back and forth, the copper cushion 936 mainly plays a buffering role, and because the copper cushion 936 is stressed to deform, so that the push rod 94 is prevented from being crushed, and the copper cushion 936 can push the push rod 94 to move back and forth when moving back and forth, thereby realizing the adjustment of the distance between the valve seat 612 and the valve core 613.

In order to ensure that the stacking spring 932 can smoothly rotate along with the T-shaped stacking spring bar 931, a certain gap exists between the stacking spring 932 and the inner wall of the support sleeve 933, and the inner diameter of the stacking spring 932 is smaller than that of the support ring 934, so that the T-shaped stacking spring bar 931 can be ensured not to contact with the inner side of the support ring 934, the T-shaped stacking spring bar 931 can conveniently rotate, and a certain gap also exists between the copper cushion 936 and the inner wall of the support sleeve 933, so that a certain space is reserved for deformation of the copper cushion 936.

When the ejector rod 94 moves forwards and backwards, the ejector rod 94 is required to be always on the same central axis with the pressurizing module 6, the ejector rod 94 is prevented from being vertically offset when moving forwards and backwards, so that the valve core 613 and the valve seat 612 are not opposite, the gap between the valve core 613 and the valve seat 612 is not inconsistent, some parts are large, some parts are small, the situation of poor uniformity is caused when materials pass through the gap between the valve seat 612 and the valve core 613, the materials are uneven, at least three guide rings 941 are arranged on the outer side of the ejector rod 94 along the axial direction of the materials, the three guide rings 941 are located between the ejector rod 94 and the supporting sleeve 933, the ejector rod 94 is slidably connected with the three guide rings 941, the guide rings 941 play a guide role, and the fact that the central axis of the ejector rod 94 is always on the same central axis with the pressurizing module 6 when moving forwards and backwards is guaranteed, the fact that the ejector rod 94 and the valve core 613 cannot be vertically offset is guaranteed, and the valve core 613 is prevented from being impacted on the inner side wall of the valve body 611 is avoided.
