[0028] The trumpet-shaped inlet slot 2 is arranged as a rounded table, the bottom end diameter of the trumpet-shaped inlet slot 2 is the same as the inner diameter of the variable-diameter radial hole 3; the opening inclination of the trumpet-shaped inlet slot 2 is set as α, the radial cutting surface inclination of the first inclined surface connecting area 7 and the second inclined surface connecting area 9 is set as β and β', respectively, the bevel hole angle of the bevelled swirl hole 10 is set as γ, and the angle values of α, β, β' and γ and the diameters of the variable-diameter radial hole 3, the variable-diameter transverse hole 8 and the bevelled swirl hole 10 are all adjustable values;

[0029] The opening inclination α of the trumpet-shaped inlet slot 2 is 20°-80°, the radial cutting surface inclinations β and β' of the first inclined surface connecting area 7 and the second inclined surface connecting area 9 can be the same or different, and the range is set to 5°-35°, and the bevel hole angle γ of the bevelled swirl hole 10 is 5°-60°.

[0030] The variable-diameter transverse hole 8 is connected to the variable-diameter radial hole 3 by penetrating the first flow slot 5 position of the core body 1, and the bevelled swirl hole 10 is provided with an outlet at the bottom end of the core body 1 by penetrating the second flow slot 6 position of the core body 1, and a plurality of variable-diameter transverse holes 8 and bevelled swirl holes 10 are arranged in a circular array along the longitudinal center line of the core body 1; the core body 1, the connecting column 4, the first inclined surface connecting area 7 and the second inclined surface connecting area 9 are integrally formed;

[0031] When a plurality of core bodies 1 are connected, the inner diameter of the matched reaction sleeve 11 is slightly larger than the outer diameter of the core body 1. The inner core body 1 itself does not need to be fixed with threads, but is fixed by other inner and outer threads matched with the reaction sleeve 11; adjacent core bodies 1 are uniformly assembled into the reaction sleeve 11 in a head-to-tail series manner, the inner wall of both ends of the reaction sleeve 11 is fixedly provided with a sealing washer 12 and an inner and outer thread for fixed sealing, and the sealing washer 12 is made of a compatible material;

[0032] A maintenance method of a detachable swirl mixing core, the maintenance method comprising the following three steps:

[0033] S1 disassembly of the swirl mixing core, the nuts fixed at both ends of the reaction sleeve 11 matched with the swirl mixing core are disassembled, and the reaction sleeve 11 can be poured out to pour out all the internal swirl mixing cores; or a solid rod of a corresponding size can be used to push out the swirl mixing cores from the other end of the reaction sleeve 11;

The inlet and outlet ends of the reaction sleeve 11 can be connected in a movable manner, preferably by snap-fit ​​connection or threaded connection.

[0036] In the above embodiments, the core body and the reaction sleeve can be made of different materials, such as stainless steel, Harbin alloy, ceramic, glass, silicon carbide, plastic or other polymer materials; the material of the matching core body can be the same as or different from that of the reaction sleeve.

[0037] In addition, the core body can be manufactured using traditional precision machining equipment, or it can be manufactured using special equipment such as 3D printing, laser processing, or other special equipment.

[0038] The specific implementation method is as follows:

[0039] This invention provides a detachable vortex mixing core, which can be mainly divided into four states in daily operation and use: normal use, disassembly, cleaning and maintenance, and reassembly (including replacement of mixing core components). The invention will be further described below with reference to the accompanying drawings:

[0040] Example 1, Regular Use:

[0041] like Figure 1 As shown, the funnel-shaped inlet groove 2, from top to bottom according to the fluid direction, is used for fluid input. Then the fluid converges into the variable diameter radial hole 3 and disperses laterally into several variable diameter transverse holes 8. The fluid reaches the connecting column 4 through the first overflow groove 5 and the first inclined surface connecting area 7, and enters the inner wall of the core body 1 through several oblique vortex holes 10 via the second oblique surface connecting area 9 and the second overflow groove 6. It then flows out through the oblique vortex hole 10 outlet at the bottom of the core body 1.

[0042] like Figure 3 As shown, this is a schematic diagram of the fluid flow channel in the device during normal use. The direction indicated by the arrow is the fluid channel. In the funnel-shaped inlet groove 2, due to the oblique cuts of several feed inlets at different angles, vortices can be formed either clockwise or counterclockwise.

[0043] like Figure 5As shown, during actual use, the vortex mixing core is sequentially loaded into the matched reaction sleeve 11. During actual use, multiple groups of core bodies 1 are loaded into the matched cylindrical reaction sleeve 11 in a manner of sequentially connecting the first end to the last end, and the sealing gasket 12 is used to ensure the sealing degree of the connection between the reaction sleeve 11 and the core body 1, and does not affect the fluid flow at the positions of the connecting column 4, the first flow slot 5 and the second flow slot 6. In the same matched reaction sleeve 11, core bodies 1 with different specifications of equal outer diameters α, β, β' and γ can be matched according to actual requirements.

[0044] Example 2, disassembly:

[0045] As shown in Figure 5 , during actual use, if scaling or blockage occurs and cleaning or maintenance is required, the nuts fixed at both ends of the vortex mixing core matched reaction sleeve 11 are disassembled, the reaction sleeve 11 is poured, and all the vortex mixing cores inside can be poured out. A solid rod of the corresponding size can also be used from one end of the reaction sleeve 11 to push the vortex mixing core out of the other end, thereby completing the disassembly process.

[0046] Example 3, cleaning and maintenance:

[0047] As shown in Figure 3 , special attention should be paid to whether there is scaling or blockage of solid foreign matter in the variable-diameter radial hole 3, the variable-diameter transverse hole 8 and the beveled vortex hole 10 during cleaning and maintenance. If scaling or blockage is found, the disassembled vortex mixing core can be placed in an ultrasonic cleaning tank for 10-20 minutes after being cleared with a matched metal filament, thereby completing the cleaning and maintenance.

[0048] Example 4, reassembly (including replacement of mixing core elements):

[0049] After cleaning and maintenance in Example 3, if it is found that some cores are severely blocked (additional maintenance treatment is required in addition to ultrasonic cleaning) and need to be replaced, or different specifications of vortex mixing cores need to be replaced according to actual conditions, reassembly is performed according to the installation steps in Example 1. According to the situation as shown in Figure 4 , select the appropriate mixing core. The core bodies 1 with different specifications of α, β, β' and γ produce different fluid disturbance effects during adjacent fluid flow after being connected, thereby achieving different use effects according to selection. Different specifications of variable-diameter cores can be used in combination, and a single core body 1 facilitates the acquisition of experience data. The operator can conveniently replace different specifications according to needs. The process opposite to the disassembly process in Example 2 is as follows: multiple groups of vortex mixing cores are loaded into the matched reaction sleeve 11 in a manner of sequentially connecting the first end to the last end, and the inlet and outlet ends can be connected in a movable manner, preferably clamping connection or threaded connection.

[0050] Example 5: A process for synthesizing easily clogged fine chemical intermediates:

[0051] In this invention, the core body 1 and the reaction sleeve 11 are combined to form a structure as shown in the figure. Figure 5 The microchannel reactor shown can be conveniently used in the synthesis process of fine chemical intermediates that are prone to clogging. Compared with the conventional Bayer Cascade microreactor mixer, which is completely disassembled, the maintenance operation time of the microreactor involved in this invention is reduced by at least 40%, or even up to 80%, from the discovery of possible clogging or scaling (such as a rapid increase in system pressure drop) to disassembly, cleaning and maintenance, possible replacement of mixing cores or units, and reassembly. This greatly improves the maintenance efficiency of process optimization or production process, and the technical requirements for operators are not high.

[0052] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.

[0054] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
