Description

Technical Field

[0001] The utility model belongs to the technical field of blood cell analyzers, and specifically relates to a hydraulic buffer type high pressure homogenizer. Background Art

[0002] High-pressure homogenizer is also called "high-pressure fluid nano-homogenizer". It can make the material in suspension state flow through a cavity with a special internal structure (high-pressure homogenization cavity) at high speed under ultra-high pressure (up to 60,000 psi), so that the material undergoes a series of changes in physical, chemical, and structural properties, and finally achieves a homogenization effect.

[0003] The high-pressure homogenizer is mainly composed of a high-pressure homogenization chamber and a pressurizing mechanism. The interior of the high-pressure homogenization chamber has a specially designed geometric shape. Under the action of the pressurizing mechanism, the high-pressure solution quickly passes through the homogenization chamber, and the material will be simultaneously subjected to mechanical forces such as high-speed shearing, high-frequency oscillation, cavitation, and convection impact, as well as corresponding thermal effects. The mechanical forces and chemical effects caused by this can induce changes in the physical, chemical and structural properties of the material macromolecules, ultimately achieving a homogenizing effect.

[0004] Traditional high-pressure homogenizers usually use a plunger pump to push the liquid through the homogenizing valve at high pressure to achieve the homogenization effect. However, during the operation of the plunger pump, due to the high-speed flow and pressure changes of the liquid, hydraulic impact force may be generated, which may cause damage to the plunger pump body and related components.

[0005] To this end, we proposed a hydraulic buffer high-pressure homogenizer, which can not only add liquid quantitatively to improve the uniformity of the liquid, but also effectively reduce the movement speed of the plunger pump body and reduce the impact of hydraulic impact force.

DETAILED DESCRIPTION

[0027] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0028] like Figure 1-4 As shown, the technical solution adopted by the utility model is as follows: a hydraulic buffer high-pressure homogenizer, comprising a liquid-carrying shell 1 and a homogenizing box 2, a first conical shell 3 connected to the liquid-carrying shell 1 is arranged at the bottom, the first conical shell 3 is wide at the top and narrow at the bottom, a suction-type buffer assembly is arranged inside the first conical shell 3, and an introduction pipe 4 is arranged at the bottom of the first conical shell 3;

[0029] The homogenizing box 2 is internally provided with a piston pump channel 5, a second conical shell 6, a homogenizing valve 7 and a derivation pipe 8 which are interconnected. The piston pump channel 5 is connected with the inlet pipe 4, and a piston pump body 9 is arranged inside the piston pump channel 5. The second conical shell 6 is narrow on the left and wide on the right, and a push-in buffer assembly is arranged inside the second conical shell 6.

[0030] Its working principle is: firstly, the liquid to be uniformly distributed enters the liquid bearing housing 1, and then the plunger pump body 9 is moved in the plunger pump channel 5 through the external oil pump. When moving to the left, Figure 2 As shown, at this time, when the plunger pump body 9 moves, internal pressure is generated, and this internal pressure causes suction to be generated. The suction causes the push-in buffer assembly inside the second conical shell 6 to move left to seal the second conical shell 6, and the suction causes the suction buffer assembly inside the first conical shell 3 to move downward to open the first conical shell 3, thereby allowing liquid to enter the plunger pump channel 5. At the same time, the push-in buffer assembly moves left to seal the second conical shell 6 to offset the hydraulic suction, reduce the movement speed of the plunger pump body 9, avoid hydraulic impact force, and cause damage. At the same time, when the liquid enters the plunger pump channel 5, the plunger pump body 9 moves to the right, thereby generating thrust, and the thrust causes the buffer assembly to move right to open the second conical shell 6, thereby allowing the liquid to enter the homogenizing valve 7 for homogenization. At the same time, the thrust generated causes the suction buffer assembly to move upward, thereby sealing the first conical shell 3, thereby offsetting the hydraulic thrust, reducing the movement speed of the plunger pump body 9, and avoiding hydraulic impact force, thereby causing damage. The device can not only add liquid quantitatively and improve the uniformity of liquid, but also effectively reduce the movement speed of the plunger pump body 9 and reduce the impact of hydraulic impact force.

[0031] Among them, the suction buffer assembly includes a filter plate 10 arranged inside the liquid-carrying shell 1, a first through hole is opened in the center of the filter plate 10, a first movable rod 11 is movably arranged inside the first through hole, a first limiting disk is installed on the top of the first movable rod 11, a first conical block 12 is installed at the position of the first movable rod 11 located inside the first conical shell 3, and a first spring 13 is sleeved on the first movable rod 11, and the first spring 13 is located between the first limiting disk and the filter plate 10.

[0032] When the plunger pump body 9 moves to the left, the suction force generated causes the first conical block 12 to drive the first movable rod 11 to move downward on the filter plate 10, thereby squeezing the first spring 13. Figure 2 As shown, at this time, the first conical housing 3 opens, allowing the liquid to enter the plunger pump channel 5. When the plunger pump body 9 moves to the right, a thrust is generated, such as Figure 3 As shown, the first conical block 12 drives the first movable rod 11 to move upward on the filter plate 10, thereby stretching the first spring 13. At this time, the first conical block 12 seals the first conical shell 3, thereby reducing the entry of gas, thereby offsetting the hydraulic thrust, reducing the movement speed of the plunger pump body 9, and avoiding hydraulic impact force and damage.

[0033] The first conical block 12 matches with the first conical shell 3 , where matching means that the first conical block 12 is also wide at the top and narrow at the bottom, and can seal the first conical shell 3 .

[0034] The push-in buffer assembly includes a fixed plate 14 arranged on the inner wall of the second conical shell 6, a second through hole is opened on the fixed plate 14, a second movable rod 15 is movably arranged inside the second through hole, a second limiting plate is installed at one end of the second movable rod 15, a second conical block 16 is installed at the other end of the second movable rod 15, and a second spring 17 is sleeved on the second movable rod 15, and the second spring 17 is located between the second conical block 16 and the fixed plate 14.

[0035] When the plunger pump body 9 moves to the left, the suction force generated causes the second conical block 16 to drive the second movable rod 15 to move to the left on the fixed plate 14, as shown in FIG. Figure 2 As shown, at this time, the second conical block 16 seals the second conical housing 6, thereby reducing the gas entering, thereby offsetting the hydraulic thrust, reducing the movement speed of the plunger pump body 9, avoiding hydraulic impact force, and being damaged. When the plunger pump body 9 moves to the right, the thrust generated is as shown in FIG. Figure 3 As shown, the second conical block 16 drives the second movable rod 15 to move rightward on the fixed plate 14, thereby squeezing the second spring 17, so that the second conical block 16 opens in the second conical housing 6, thereby homogenizing the liquid.

[0036] The second conical block 16 matches with the second conical shell 6 , where matching means that the second conical block 16 is also narrow and wide, and can seal the second conical shell 6 .

[0037] The working principle of the homogenizing valve 7 is as follows: when the liquid enters the homogenizing valve 7, it is subjected to high-speed shearing, impact and cavitation, which can break large particles in the liquid into small particles, making the liquid more uniform and delicate.

[0038] Specifically, there are usually one or more small channels in the homogenizing valve 7, and the liquid will be subjected to strong shear force when passing through these channels. At the same time, the liquid will also form a high-speed vortex in the homogenizing valve 7, which will produce an impact effect. In addition, in some cases, cavitation bubbles may also form in the liquid. When the cavitation bubbles burst, they will produce instantaneous high pressure and high-speed impact, further promoting the crushing and homogenization of particles.

[0039] Through the above process, the homogenizing valve 7 can effectively improve the homogenizing effect of the liquid, making the output liquid more stable and uniform. The working effect of the homogenizing valve 7 depends on factors such as its structural design, material selection, and operating conditions. Different types of homogenizing valves 7 may have different characteristics and applicable scopes, and need to be selected and optimized according to specific application requirements.

[0040] In the hydraulic buffer type high pressure homogenizer, the operation of the homogenizing valve 7 is closely related to the movement of the plunger pump body 9 and the coordinated action of other components. By reasonably controlling the operating parameters of the homogenizing valve 7, the liquid homogenizing effect can be precisely controlled.

[0041] It should be noted that the plunger pump body 9 is connected and driven by a hydraulic oil pump provided externally, and the hydraulic oil pump can drive the plunger pump body 9 to perform reciprocating motion, which belongs to the prior art and will not be elaborated on here.

[0042] A sealing cover (not shown in the figure) is arranged on the liquid bearing housing 1, and the sealing cover can prevent external dust from entering into the liquid and causing damage to the liquid.

[0043] The working principle of the utility model is: firstly, the liquid to be uniformly distributed enters the liquid bearing housing 1, and then the plunger pump body 9 is moved in the plunger pump channel 5 by the external oil pump. When moving to the left, Figure 2 As shown, at this time, when the plunger pump body 9 moves, internal pressure is generated, and this internal pressure causes suction to be generated. The suction causes the push-in buffer assembly inside the second conical shell 6 to move left to seal the second conical shell 6, and the suction causes the suction buffer assembly inside the first conical shell 3 to move downward to open the first conical shell 3, thereby allowing liquid to enter the plunger pump channel 5. At the same time, the push-in buffer assembly moves left to seal the second conical shell 6 to offset the hydraulic suction, reduce the movement speed of the plunger pump body 9, avoid hydraulic impact force, and cause damage. At the same time, when the liquid enters the plunger pump channel 5, the plunger pump body 9 moves to the right, thereby generating thrust, and the thrust causes the buffer assembly to move right to open the second conical shell 6, thereby allowing the liquid to enter the homogenizing valve 7 for homogenization. At the same time, the thrust generated causes the suction buffer assembly to move upward, thereby sealing the first conical shell 3, thereby offsetting the hydraulic thrust, reducing the movement speed of the plunger pump body 9, and avoiding hydraulic impact force, thereby causing damage. The device can not only add liquid quantitatively and improve the uniformity of liquid, but also effectively reduce the movement speed of the plunger pump body 9 and reduce the impact of hydraulic impact force.

[0044] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
