Description

Technical Field

[0001] This invention relates to the field of mixing and stirring equipment technology, and more specifically, to a plant growth regulator processing device. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] Plant growth regulators (also known as plant growth modulators) are a class of chemical substances that are artificially synthesized and can regulate plant growth and development. They are widely used in agricultural production to regulate crop growth processes, increase yield, and improve quality.

[0004] Catalytic reactions are a common process in the synthesis and preparation of plant growth regulators. Many plant growth regulators require catalysts to complete chemical reactions such as esterification, condensation, and addition. Solid catalysts are widely used in the industrial production of plant growth regulators due to their advantages such as ease of separation and recovery, reusability, and low corrosiveness to equipment. Furthermore, mixing devices used for processing plant growth regulators typically include a mixing tank, a stirring motor mounted on the tank, and a stirring shaft driven by the motor. The stirring shaft is equipped with stirring blades, and its rotation stirs and mixes the reactants within the tank.

[0005] In the preparation process of plant growth regulators using solid catalysts, to facilitate catalyst recovery and reuse, the solid catalyst is typically placed in a porous filter assembly (such as a filter box or catalyst basket) fixedly installed inside a mixing tank. These filter assemblies have pores in their walls, allowing liquid materials from the mixing tank to enter and exit the filter assembly and come into contact with the catalyst, while the solid catalyst is retained inside the filter assembly. However, because the installation position of the filter assembly within the mixing tank is fixed, only the liquid materials near the filter assembly can fully contact the catalyst inside, while areas farther away from the filter assembly do not receive equal catalytic reaction opportunities. This may lead to inconsistent catalytic reaction processes in different areas of the tank, limiting the overall catalytic efficiency. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a plant growth regulator processing device to at least solve the technical problem that it is difficult to achieve uniform catalytic contact throughout the entire tank due to the limited distribution range of the catalyst in existing plant growth regulator processing devices.

[0007] The objective of this invention is achieved through the following technical solution: This invention provides a plant growth regulator processing device, comprising: Mixing tank; A stirring mechanism includes a stirring shaft extending into the mixing tank; the stirring shaft is configured to rotate about its own axis, and a stirring component located within the mixing tank is provided on the stirring shaft.

[0010] Optionally, the bracket is provided with a limiting groove located below the transmission screw and extending along the axial direction of the transmission screw, the limiting groove penetrating the upper and lower surfaces of the bracket; The movable seat passes through the limiting groove and connects to the filter cylinder, and the movable seat and the limiting groove are in sliding fit.

[0011] Optionally, the transmission screw is a reciprocating screw.

[0012] Optionally, the axial length of the filter cylinder is not less than the axial length of the stirring component.

[0013] Optionally, there may be multiple filter cylinders, which are arranged sequentially and evenly along the circumference of the stirring shaft.

[0014] Optionally, a rotating shaft is coaxially arranged inside the filter cartridge, and the rotating shaft is configured to rotate about its own axis. The rotating shaft is equipped with an agitator located inside the filter cylinder.

[0015] Optionally, the movable seat has an axially extending cavity inside; the top end of the rotating shaft extends into the cavity and is rotatably connected to the inner top wall of the cavity. The outer wall of the rotating shaft is coaxially fitted with a transmission gear located in the cavity; The side wall of the movable seat has an opening that communicates with the cavity, and part of the transmission gear is exposed outside the cavity through the opening; The bracket is provided with a radially extending rack, which meshes with the transmission gear.

Simultaneously, a transmission mechanism drives the filter cartridge to perform reciprocating linear motion radially along the stirring shaft. This creates a dynamic sweeping motion within the horizontal cross-section of the mixing tank, with its trajectory covering the annular area from the outer edge of the stirring component to the inner wall of the mixing tank. In this way, the solid catalyst inside the filter cartridge can fully contact the liquid material at different radial and height positions within the mixing tank, significantly improving the uniformity and efficiency of the catalytic reaction.

[0022] Example 1

[0023] The inventors of this invention have discovered that, in the catalytic reaction of plant growth regulators using solid catalysts, existing mixing devices typically place the solid catalyst within a porous filter assembly fixedly installed inside the mixing tank 10. Because the filter assembly's installation position within the mixing tank 10 is fixed, only the liquid material near the filter assembly can fully contact the catalyst inside, while areas far from the filter assembly struggle to obtain equal catalytic reaction opportunities. This results in inconsistent catalytic reaction processes in different areas of the tank, limiting the overall catalytic efficiency.

[0024] In response, at least one embodiment of the present invention provides a plant growth regulator processing apparatus, including a mixing tank 10, a stirring mechanism 20, and a catalytic unit 30. The mixing tank 10 is used to contain the reaction materials required for the processing of plant growth regulators. The stirring mechanism 20 includes a stirring shaft 22 extending into the mixing tank 10, the stirring shaft 22 being configured to rotate about its own axis, and a stirring component 23 located within the mixing tank 10 is provided on the stirring shaft 22. The stirring component 23 rotates synchronously with the stirring shaft 22 to stir and mix the reaction materials within the mixing tank 10.

[0025] The catalytic unit 30 includes a support 31, a filter cartridge 32, and a transmission mechanism 33. The support 31 is fixedly connected to the stirring shaft 22, allowing the support 31 to rotate synchronously with the stirring shaft 22 around its own axis. The filter cartridge 32 contains a solid catalyst (not shown in the figure) and extends axially along the stirring shaft 22; that is, the length direction of the filter cartridge 32 is parallel to the axial direction of the stirring shaft 22. The filter cartridge 32 is located between the stirring component 23 and the inner wall of the mixing tank 10; that is, the filter cartridge 32 is positioned radially outside the stirring component 23 to avoid interference with the stirring component 23 during movement. The transmission mechanism 33 is mounted on the support 31, and the number of transmission mechanisms 33 corresponds one-to-one with the number of filter cartridges 32; that is, each filter cartridge 32 is equipped with one transmission mechanism 33. The transmission mechanism 33 is configured to output reciprocating linear motion radially along the stirring shaft 22. The filter cartridge 32 is connected to the output end of the transmission mechanism 33.

[0026] The processing apparatus provided in this embodiment of the invention fixes the support 31 to the stirring shaft 22, allowing the axially extending filter cylinder 32 to revolve around the stirring shaft 22 with the support 31. Simultaneously, the transmission mechanism 33 drives the filter cylinder 32 to reciprocate linearly along the stirring shaft 22 in a radial direction. This results in the filter cylinder 32 forming a dynamic sweeping motion within the horizontal cross-section of the mixing tank 10, with its trajectory covering the annular area between the outer edge of the stirring component 23 and the inner wall of the mixing tank 10. In this way, the solid catalyst inside the filter cylinder 32 can fully contact the liquid material at different radial and height positions within the mixing tank 10, significantly improving the uniformity and efficiency of the catalytic reaction and effectively solving the technical problem of limited catalyst distribution range in the prior art.

[0027] The embodiments and examples of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] For ease of description, in this embodiment of the invention, the axial direction of the stirring shaft 22 is defined as axial, and the direction perpendicular to this axis is defined as radial. The mixing tank 10 is generally cylindrical, extending axially; the stirring shaft 22 is located at the central axis of the mixing tank 10 and is coaxial with the mixing tank 10. "Radially inner side" refers to the side radially closer to the stirring shaft 22, and "radially outer side" refers to the side radially away from the stirring shaft 22. All orientations in this invention are relative positions and do not limit the scope of the invention.

[0029] like Figure 1 As shown, at least one embodiment of the present invention provides a plant growth regulator processing apparatus, including a mixing tank 10, a stirring mechanism 20, and a catalytic unit 30. The mixing tank 10 is used to contain the reaction materials required for the processing of plant growth regulators. The mixing tank 10 is generally cylindrical in shape extending along the axial direction, with a feed inlet 11 at the top and a discharge outlet 12 at the bottom. The reaction materials are fed into the mixing tank 10 through the feed inlet 11 and discharged through the discharge outlet 12 after processing.

[0030] The stirring mechanism 20 includes a stirring motor 21, a stirring shaft 22, and a stirring component 23. The stirring motor 21 is fixedly mounted on the top of the mixing tank 10. The upper end of the stirring shaft 22 is connected to the stirring motor 21, and the stirring motor 21 drives the stirring shaft 22 to rotate around its own axis. The lower end of the stirring shaft 22 extends axially into the interior of the mixing tank 10. The stirring component 23 is fixedly mounted on the part of the stirring shaft 22 located inside the mixing tank 10. The stirring component 23 rotates synchronously with the stirring shaft 22 to stir and mix the reactants in the mixing tank 10. The stirring component 23 can be a conventional form such as a spiral stirring blade or a paddle stirring blade, and this embodiment of the invention does not limit this.

[0031] The catalytic unit 30 is disposed inside the mixing tank 10 and is used to carry the solid catalyst and ensure sufficient contact between the catalyst and the liquid material. The catalytic unit 30 includes a support 31, a filter cartridge 32, and a transmission mechanism 33. The support 31 is fixedly connected to the stirring shaft 22, so that the support 31 can rotate synchronously with the stirring shaft 22. The support 31 extends radially in a slender plate-like structure, with its thickness direction along the axial direction and its width direction along the circumferential direction, so as to avoid the support 31 obstructing the material falling into the feed inlet 11.

[0032] The filter cartridge 32 contains a solid catalyst (not shown in the figure). The solid catalyst can be a solid acid catalyst, a supported metal catalyst, or any other solid catalyst suitable for regulating auxin synthesis reactions in plants. The filter cartridge 32 is generally a hollow cylindrical structure with filter holes on its outer wall that communicate with its interior. The pore size should be smaller than the minimum particle size of the solid catalyst to prevent catalyst particles from leaking from the filter cartridge 32. For example, the diameter of the filter holes can be from 0.5 mm to 2 mm, depending on the particle size of the catalyst.

[0033] The filter cylinder 32 extends along the axial direction of the stirring shaft 22, that is, the axis of the filter cylinder 32 is parallel to the axis of the stirring shaft 22. The filter cylinder 32 is located between the stirring component 23 and the inner wall of the mixing tank 10, that is, the filter cylinder 32 is radially positioned on the outer side of the stirring component 23 and the inner side of the inner wall of the mixing tank 10, so that the filter cylinder 32 will not interfere with the stirring component 23 during the revolution and radial movement of the support 31.

[0034] The transmission mechanism 33 is mounted on the support 31. The number of transmission mechanisms 33 corresponds one-to-one with the number of filter cartridges 32, meaning each filter cartridge 32 is equipped with one transmission mechanism 33. The input end of the transmission mechanism 33 is driven by the stirring shaft 22 to obtain rotational power from the stirring shaft 22. The transmission mechanism 33 is configured to convert the rotational motion output from the stirring shaft 22 into a reciprocating linear motion along the radial direction of the stirring shaft 22, and output this reciprocating linear motion to the filter cartridge 32. This design eliminates the need for a separate power source for the transmission mechanism 33.

[0035] The filter cartridge 32 is connected to the output end of the transmission mechanism 33, so that when the stirring shaft 22 rotates, the filter cartridge 32 can revolve around the stirring shaft 22 with the support 31 and simultaneously make reciprocating linear motion along the radial direction of the stirring shaft 22.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the transmission mechanism 33 may adopt a specific structural form in which a bevel gear and a transmission screw 332 are coupled.

[0037] Specifically, a main bevel gear 40 is fixedly installed at the inner top of the mixing tank 10. The main bevel gear 40 is coaxially arranged with the stirring shaft 22, that is, the axis of the main bevel gear 40 coincides with the axis of the stirring shaft 22. The main bevel gear 40 is fixedly installed at the inner top of the mixing tank 10 and remains stationary relative to the mixing tank 10, not rotating with the stirring shaft 22. A through hole is opened in the center of the main bevel gear 40, through which the stirring shaft 22 passes. There is a gap between the stirring shaft 22 and the main bevel gear 40, or a rotational engagement through a bearing, so that the stirring shaft 22 can rotate freely without driving the main bevel gear 40 to rotate.

[0038] The transmission mechanism 33 includes a secondary bevel gear 331, a transmission screw 332, and a movable base 333. The transmission screw 332 is rotatably mounted on the bracket 31 and extends radially along the stirring shaft 22. One end of the transmission screw 332 is mounted on the bracket 31 near the stirring shaft 22 via a bearing seat, and the other end is mounted on the bracket 31 away from the stirring shaft 22 via a bearing seat. The transmission screw 332 can rotate freely about its own axis. The secondary bevel gear 331 is coaxially fixed to the transmission screw 332.

[0039] In some embodiments of the present invention, the secondary bevel gear 331 is fixed to one end of the transmission screw 332 near the stirring shaft 22. The secondary bevel gear 331 meshes with the primary bevel gear 40. Since the primary bevel gear 40 is stationary, when the support 31 revolves with the stirring shaft 22, the secondary bevel gear 331 revolves with the support 31. During the revolution, the secondary bevel gear 331 rolls along the tooth surface of the stationary primary bevel gear 40, thereby causing the secondary bevel gear 331 to rotate around its own axis, and thus driving the transmission screw 332 to rotate synchronously.

[0040] The movable seat 333 is threadedly engaged with the transmission screw 332. That is, the movable seat 333 has an internal thread hole that matches the external thread of the transmission screw 332. The transmission screw 332 passes through the internal thread hole, and the movable seat 333 can slide along the axial direction of the transmission screw 332.

[0041] The bracket 31 is provided with limiting grooves 311 corresponding to the transmission mechanism 33. The limiting grooves 311 are located below the transmission screw 332 and extend along the axial direction of the transmission screw 332. The limiting grooves 311 penetrate the upper and lower surfaces of the bracket 31. The movable seat 333 passes through the corresponding limiting groove 311 and connects to the corresponding filter cartridge 32. The outer wall of the movable seat 333 and the inner wall of the limiting groove 311 are in sliding fit. The limiting grooves 311 guide and prevent the movable seat 333 from rotating with the transmission screw 332, so that the movable seat 333 can only perform reciprocating linear motion along the axial direction of the transmission screw 332.

[0042] When the lead screw 332 rotates, based on the principle of threaded transmission, the moving seat 333 will move along the axial direction of the lead screw 332. The lead screw 332 can be a regular lead screw or a reciprocating lead screw. When the lead screw 332 is a reciprocating lead screw, the lead screw 332 can drive the moving seat 333 to automatically reverse direction during continuous unidirectional rotation, realizing reciprocating linear motion, without the need for reverse rotation of the lead screw 332 or the setting of an additional reversing mechanism. In some embodiments of the present invention, the lead screw 332 is preferably a reciprocating lead screw to accommodate the continuous unidirectional rotation of the stirring shaft 22.

[0043] The filter cartridge 32 is connected to the lower end of the movable base 333. Specifically, the upper end of the filter cartridge 32 is connected to the lower end of the movable base 333, and the main body of the filter cartridge 32 extends downward along the axial direction. The filter cartridge 32 and the movable base 333 can be fixedly connected or detachably connected.

[0044] In some embodiments of the present invention, the filter cartridge 32 and the movable base 333 are detachably connected. The detachable connection can be made by means including, but not limited to, snap-fit ​​connection, flange connection, etc. The detachable connection facilitates the replacement of the filter cartridge 32, the replenishment of the catalyst, and the cleaning and maintenance of the filter cartridge 32.

[0045] In some embodiments of the present invention, the axial length of the filter cylinder 32 is not less than the axial length of the stirring member 23, that is, the axial extension range of the filter cylinder 32 at least covers the axial working range of the stirring member 23. Thus, when the liquid material flows axially under the drive of the stirring member 23, the liquid material flowing through the filter cylinder 32 can be fully acted upon by the stirring member 23, minimizing the possibility of unstirred liquid material directly contacting the catalyst through the filter cylinder 32, thereby further improving the uniformity of the catalytic reaction.

[0046] The working process of the plant growth regulator processing device provided in Embodiment 1 of the present invention will be described below with reference to the accompanying drawings.

[0047] In the initial state, the filter cartridge 32 is located in the initial position along with the support 31, for example... Figure 1 As shown, the drive screw 332 and the moving seat 333 are stationary, and the filter cartridge 32 is pre-filled with a solid catalyst. The operator feeds the reaction material of the plant growth regulator into the mixing tank 10 through the feed inlet 11 at the top of the mixing tank 10.

[0048] Then, the stirring motor 21 is started, driving the stirring shaft 22 to rotate around its own axis. The rotation of the stirring shaft 22 causes the stirring component 23 to rotate synchronously, and the stirring component 23 stirs and mixes the reactants in the mixing tank 10. At the same time, the rotation of the stirring shaft 22 causes the support 31 to revolve synchronously. When the support 31 revolves, the secondary bevel gear 331 mounted on the support 31 revolves around the stirring shaft 22 along with the support 31. Since the main bevel gear 40 is fixedly mounted in the mixing tank 10 and maintains meshing with the secondary bevel gear 331, the secondary bevel gear 331 rolls along the tooth surface of the main bevel gear 40 during its revolution, causing the secondary bevel gear 331 to rotate around its own axis, thereby driving the transmission screw 332 to rotate synchronously.

[0049] When the drive screw 332 rotates, based on the principle of threaded transmission, the movable seat 333 will move axially along the drive screw 332, that is, radially along the stirring shaft 22. The movable seat 333 drives the filter cylinder 32 to move radially synchronously. When the drive screw 332 is a reciprocating screw, the drive screw 332 drives the movable seat 333 to automatically reverse direction during the continuous unidirectional rotation, so that the movable seat 333 drives the filter cylinder 32 to perform reciprocating linear motion in the radial direction, without the need to control the drive screw 332 to reverse. Thus, the motion of the filter cylinder 32 in the mixing tank 10 is a combination of two motions: one is the circular motion of the support 31 revolving around the stirring shaft 22, and the other is the reciprocating linear motion in the radial direction of the stirring shaft 22. After the two motions are superimposed, the filter cylinder 32 forms a dynamic sweeping motion in the horizontal section of the mixing tank 10, and its motion trajectory covers the annular area between the outer edge of the stirring component 23 and the inner wall of the mixing tank 10.

[0050] During the movement of the filter cartridge 32, the liquid material in the mixing tank 10 flows continuously under the action of the stirring component 23. Liquid material at different radial positions flows sequentially through the outer wall of the filter cartridge 32, enters the interior of the filter cartridge 32 through the filter holes, and undergoes a catalytic reaction after contacting the solid catalyst. Then, it flows out from the interior of the filter cartridge 32. Because the filter cartridge 32 continuously sweeps within the horizontal cross-section, liquid material at different radial and height positions in the mixing tank 10 has the opportunity to flow through the filter cartridge 32 and contact the catalyst, thereby achieving uniform distribution and catalytic contact of the catalyst throughout the entire tank.

[0051] Once the catalytic reaction is complete, turn off the stirring motor 21, stop the stirring shaft 22 from rotating, and stop the support 31 and filter cartridge 32 from moving. The processed reaction material is discharged from the outlet 12 at the bottom of the mixing tank 10. If it is necessary to replace the catalyst or clean the filter cartridge 32, the filter cartridge 32 can be removed from the moving base 333, cleaned, or the catalyst replaced and then reinstalled.

[0052] In some embodiments of the present invention, the number of filter cylinders 32 can be one or more. When there are multiple filter cylinders 32, they are arranged sequentially and uniformly along the circumference of the stirring shaft 22, that is, the circumferential angle between adjacent filter cylinders 32 is equal, so as to exert a catalytic effect at different circumferential positions of the mixing tank 10 simultaneously, thereby improving the catalytic efficiency. For example, when there are two filter cylinders 32, the two filter cylinders 32 are arranged 180° apart circumferentially; when there are three filter cylinders 32, the three filter cylinders 32 are arranged 120° apart circumferentially. Each filter cylinder 32 is correspondingly equipped with a transmission mechanism 33, and the structure and working principle of each transmission mechanism 33 are the same. The multiple filter cylinders 32 simultaneously revolve with the support 31 and reciprocate linearly in the radial direction, forming multiple dynamic sweeping points in the horizontal cross section of the mixing tank 10, further improving the uniformity and efficiency of the catalytic reaction.

[0053] Example 2

[0054] Based on Example 1, Example 2 of the present invention provides another plant growth regulator processing device.

[0055] Unlike Example 1, the inventors of this invention further discovered that when the catalyst in the filter cartridge 32 is a granular solid catalyst, the filter cartridge 32 remains stationary as it revolves with the support 31 and moves in a reciprocating linear motion along the radial direction. After the liquid material flows into the filter cartridge 32, it mainly contacts the catalyst near the filter holes, while the catalyst in the central area of ​​the filter cartridge 32 has difficulty making sufficient contact with the liquid material, resulting in a contact "dead zone". This leads to a reduction in the utilization rate of some catalysts and affects the overall efficiency of the catalytic reaction.

[0056] In this regard, such as Figure 3 As shown, in Embodiment 2 of the present invention, a rotating shaft 50 is coaxially disposed inside the filter cylinder 32. The rotating shaft 50 is configured to rotate about its own axis. Specifically, the rotating shaft 50 extends axially along the filter cylinder 32, and a stirring member 51 is provided at the portion of the rotating shaft 50 located inside the filter cylinder 32. The stirring member 51 is used to agitate the particulate catalyst inside the filter cylinder 32. For example, the stirring member 51 can be at least one of a stirring blade, a stirring rod, or a spiral protrusion, and is fixedly disposed on the outer wall of the rotating shaft 50.

[0057] Based on the above configuration, when the rotating shaft 50 rotates, the stirring component 51 rotates synchronously with the rotating shaft 50 to stir the granular catalyst inside the filter cylinder 32, so that the catalyst particles inside the filter cylinder 32 are constantly turned over, so that the catalyst particles in different positions can be exposed near the filter holes of the filter cylinder 32 and fully contact the liquid material flowing through the filter cylinder 32.

[0058] like Figures 3 to 5 As shown, in some embodiments of the present invention, the interior of the movable base 333 is provided with an axially extending cavity 334. The top end of the rotating shaft 50 passes through the top of the filter cartridge 32 and extends into the cavity 334, and is rotatably connected to the inner top wall of the cavity 334. Specifically, the inner top wall of the cavity 334 is provided with a mounting hole, in which a bearing is embedded. The top end of the rotating shaft 50 is inserted into the inner ring of the bearing and fixedly connected to the inner ring of the bearing, while the outer ring of the bearing is fixedly connected to the inner top wall of the cavity 334. In this way, the rotating shaft 50 can rotate freely relative to the movable base 333 about its own axis, while being axially fixed to the movable base 333. When the movable base 333 moves radially, it can drive the rotating shaft 50 to move synchronously.

[0059] A transmission gear 52 is coaxially sleeved on the outer wall of the rotating shaft 50, and the transmission gear 52 is located within the cavity 334. An opening 335 communicating with the cavity 334 is formed in the side wall of the movable seat 333, through which a portion of the transmission gear 52 is exposed outside the cavity 334. The opening 335 extends axially along the movable seat 333, and its axial dimension is greater than or equal to the thickness of the transmission gear 52. The circumferential dimension of the opening 335 is configured to allow a portion of the teeth of the transmission gear 52 to protrude from the opening 335, and the transmission gear 52 can rotate freely during radial movement with the movable seat 333, without its exposed portion interfering with the edge of the opening 335. The side wall of the movable seat 333 remains fully connected outside the opening 335, and the overall structural strength of the movable seat 333 is not affected.

[0060] A radially extending rack 53 is provided on the support 31, and the rack 53 is fixedly mounted on the support 31 and arranged parallel to the transmission screw 332. The portion of the transmission gear 52 exposed outside the cavity 334 through the opening 335 is engaged with the rack 53. When the moving seat 333 moves radially, the transmission gear 52 moves synchronously with the moving seat 333, rolling along the fixed rack 53 during the movement, thereby driving the transmission gear 52 to rotate around its own axis. The rotation of the transmission gear 52 drives the rotating shaft 50 to rotate synchronously, and the rotating shaft 50 drives the agitator 51 on it to rotate, and the agitator 51 continuously agitates the granular catalyst inside the filter cartridge 32.

[0061] Thus, in Embodiment 2 of the present invention, while the filter cylinder 32 revolves with the support 31 and performs reciprocating linear motion in the radial direction, the rotating shaft 50 and the agitating component 51 inside the filter cylinder 32 automatically rotate during the movement of the moving seat 333, continuously agitating the granular catalyst inside the filter cylinder 32. This achieves dynamic tumbling of the catalyst particles within the filter cylinder 32 without the need for an additional independent power source. This design ensures that catalyst particles at different positions within the filter cylinder 32 can continuously tumble, guaranteeing that all catalyst particles within the filter cylinder 32 are fully exposed to and in contact with the liquid material, further improving the catalyst utilization efficiency and the uniformity of the catalytic reaction.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
