High-pressure cylinder applied to micro-jet homogenizer

Abstract

According to the high-pressure cylinder applied to the micro-jet homogenizer, the high-pressure cylinder is fixedly installed on the micro-jet homogenizer through the sleeve, the cylinder body penetrates through the assembly channel to be assembled in the sleeve, and the material conveying channel used for being communicated with the pressurization space is located in the cylinder body, so that the material conveying channel can be cleaned and maintained when the material conveying channel needs to be cleaned and maintained, and the material conveying channel is not required to be replaced. When the cylinder body with the material conveying channel is assembled on the sleeve or the damaged material conveying channel needs to be replaced, only the cylinder body with the material conveying channel needs to be pulled out of the assembly channel on the sleeve, and only the cylinder body with the material conveying channel needs to be pushed into the assembly channel on the sleeve during installation, so that convenient disassembly and assembly are realized, and meanwhile, the material conveying channel can be replaced. Due to the fact that the outer wall of the middle portion of the cylinder body is concaved inwards to form the receding part which keeps a distance with the inner wall of the assembly channel, when the cylinder body is pulled out of the assembly channel and pushed into the assembly channel, friction between the cylinder body and the inner wall of the assembly channel is reduced, and disassembly and assembly are more convenient. The utility model belongs to the technical field of microjet homogenizers.

Description

Technical Field

[0001] The utility model belongs to the technical field of micro-jet homogenizers, and in particular relates to a high-pressure cylinder applied to the micro-jet homogenizer. Background Art

[0002] A microfluidizer is a device that uses high-pressure microjet technology to achieve material homogenization, emulsification, crushing, and dispersion. Its working principle is mainly to pressurize the material to a higher pressure through a high-pressure pump, and then pass the material through a microchannel with a special internal structure at high speed. When the material passes through the microchannel at high speed, the pressure in the fluid drops sharply to form a supersonic flow rate. At this time, particle collisions, cavitation, leakage, shearing and other phenomena will occur in the fluid.

[0003] In conventional microfluidizers, the channel for inputting or outputting materials is generally a single material pipe directly fixed to the microfluidizer. Therefore, when the single material pipe needs to be maintained or replaced, it is difficult to remove the material pipe from the microfluidizer and inconvenient to install a new material pipe on the microfluidizer. Utility Model Content

[0004] The purpose of the utility model is to provide a high-pressure cylinder used in a micro-jet homogenizer to solve the technical problems described in the background art.

[0005] The high-pressure cylinder used in a micro-jet homogenizer includes a sleeve and a cylinder body, the sleeve is fixedly installed on the micro-jet homogenizer, an assembly channel is provided in the sleeve, and a material delivery channel is provided in the cylinder body that runs through both ends thereof, one end of the material delivery channel is used to be connected to a feed valve, and the other end of the material delivery channel is used to be connected to the pressurized space of the micro-jet homogenizer through a high-pressure pipeline, the cylinder body is assembled in the sleeve by penetrating the assembly channel, the outer periphery of both ends of the cylinder body protrudes outwardly with positioning support parts that contact the inner walls of both ends of the assembly channel, and the outer wall of the middle part of the cylinder body is recessed inward to have a avoidance part that keeps a distance from the inner wall of the assembly channel.

[0006] According to the technical solution, the utility model can achieve the following beneficial effects:

[0007] 1. Since the sleeve is fixedly mounted on the micro-jet homogenizer, and the cylinder body is assembled in the sleeve by passing through the assembly channel, and the feed channel used in conjunction with the pressurized space is located in the cylinder body, when the feed channel needs to be cleaned and maintained, or when a damaged feed channel needs to be replaced, it is only necessary to pull the cylinder body with the feed channel out of the assembly channel on the sleeve. When installing, it is only necessary to push the cylinder body with the feed channel into the assembly channel on the sleeve, thereby realizing convenient disassembly and installation;

[0008] 2. Because the outer wall of the middle part of the cylinder body is recessed inward to form a relief portion that keeps a distance from the inner wall of the assembly channel, when the cylinder body is pulled out of the assembly channel or when the cylinder body is pushed into the assembly channel, the friction between the cylinder body and the inner wall of the assembly channel is reduced, making it easier to disassemble and install;

[0009] 3. Positioning support parts protrude outward from the outer periphery of both ends of the cylinder body and contact the inner walls of both ends of the assembly channel, so that after the cylinder body is pushed into the assembly channel, the feed channel on the cylinder body can be positioned and aligned;

[0010] 4. Since the sleeve is mounted on the cylinder body, the conveying channel becomes a double-layer package, thereby making the conveying channel stronger.

[0011] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0012] In some embodiments, one end of the feed channel is provided with a first chamfer for hard sealing connection with the feed valve;

[0013] According to the technical solution, a first chamfer is provided around the outlet at one end of the material delivery channel, so that the feed valve can be hard-sealed with the material delivery channel.

[0014] In some embodiments, the other end of the feed channel is provided with a second chamfer for hard-sealing connection with the high-pressure pipe;

[0015] According to the technical solution, a second chamfer is provided around the outlet of one end of the feed channel, so that the high-pressure pipe can be hard-sealed with the feed channel. In addition, the two ends of the feed channel can be clamped by the high-pressure pipe and the pressure relief valve to achieve a hard-sealed connection.

[0016] In some embodiments, the diameter of the assembly channel is greater than 64, the diameter of the positioning support portion is 64, and the diameter of the avoidance portion is 63;

[0017] According to the technical solution, the friction between the cylinder body and the inner wall of the assembly channel can be reduced while ensuring the strength of the outer wall of the feeding channel.

[0018] In some embodiments, the length of the cylinder is 146, and the length of the avoidance portion is 108;

[0019] According to the technical solution, the friction area between the cylinder body and the inner wall of the assembly channel can be reduced while ensuring that the feeding channel can be positioned and supported.

[0020] In some embodiments, a guide chamfer for guiding the cylinder into the assembly channel is arranged at the opening of both ends of the assembly channel, and a fillet for sliding on the guide chamfer is arranged on the outer periphery of both ends of the cylinder.

[0021] According to the technical scheme, during the process of pushing the cylinder into the assembly channel on the sleeve, the fillet on the cylinder is firstly slid on the guide chamfer, and then the outer periphery of the cylinder is also slid on the guide chamfer, so that the cylinder is guided into the assembly channel.

[0029] As Figures 1 to 3 shown, the present specific embodiment provides a high-pressure cylinder applied to a micro-fluid homogenizer, which comprises a sleeve 1 and a cylinder 2.

[0030] The sleeve 1 is fixedly installed on the micro-fluid homogenizer, and the sleeve 1 is provided with an assembly channel 11, and a guide chamfer 12 for guiding the cylinder 2 into the assembly channel 11 is arranged at the opening of both ends of the assembly channel 11.

[0031] The outer periphery of both ends of the cylinder body 2 is provided with rounded corners 26 for sliding on the guide chamfers 12. The cylinder body 2 is assembled in the sleeve 1 by passing through the assembly channel 11. The outer periphery of both ends of the cylinder body 2 protrudes outwardly with positioning support portions 22 that contact the inner walls of the assembly channel 11 at both ends. The outer wall of the middle portion of the cylinder body 2 is recessed inwardly to form an avoidance portion 23 that maintains a distance from the inner wall of the assembly channel 11. The diameter of the assembly channel 11 can be greater than 64 and can be infinitely close to 64. The diameter of the positioning support portion 22 is 64, and the diameter of the avoidance portion 23 is 63. The length of the cylinder body 2 is 146, and the length of the avoidance portion 23 is 108.

[0032] The cylinder body 2 is provided with a feed channel 21 extending through both ends thereof. One end of the feed channel 21 is provided with a first chamfer 24 for a hard-seal connection with the feed valve 3, and the other end of the feed channel 21 is provided with a second chamfer 25 for a hard-seal connection with the high-pressure pipe. This allows the feed channel 21 to be connected to the pressurized space of the microfluidizer via the high-pressure pipe 4. The high-pressure pipe and the pressure relief valve clamp both ends of the feed channel 21, thereby achieving a hard-seal connection.

[0033] The following is an instruction for using the high-pressure cylinder used in the microfluidizer.

[0034] When assembling the cylinder body 2, just push the cylinder body 2 with the feed channel 21 into the assembly channel 11 on the sleeve 1; in the process of pushing the cylinder body 2 into the assembly channel 11, the chamfer 26 on the cylinder body 2 slides on the guide chamfer 12 in advance, and then the outer periphery of the cylinder body 2 will also slide on the guide chamfer 12, thereby realizing the cylinder body 2 being introduced into the assembly channel 11. At the same time, the avoidance portion 23 does not contact or rub with the inner wall of the assembly channel 11; after the assembly of the cylinder body 2 is completed, the avoidance portion 23 remains free from contact or friction with the inner wall of the assembly channel 11, and the positioning support portions 22 protruding outward from the outer periphery of both ends of the cylinder body 2 contact the inner walls of both ends of the assembly channel 11 to support the cylinder body 2 and position the feed channel 21.

[0035] When disassembling the cylinder body 2 , the cylinder body 2 with the material delivery channel 21 can be pulled out from the assembly channel 11 on the sleeve 1 ; during the process of pulling the cylinder body 2 out of the assembly channel 11 , the avoidance portion 23 does not contact or rub against the inner wall of the assembly channel 11 .

[0036] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application.
