Description

Technical Field

[0001] The utility model belongs to the technical field of gas-liquid-solid three-phase reaction kettles, and in particular relates to a stirring device for a gas-liquid-solid three-phase reaction kettle. Background Art

[0002] A reactor is a type of container for physical or chemical reactions, while a gas-liquid-solid three-phase reactor is a reactor for gas-liquid-solid three-phase reactions, which are widely used in the fields of petroleum, chemical industry, rubber, pesticides, medicine and food. The stirring device of a gas-liquid-solid three-phase reactor is a stirring component arranged inside a gas-liquid-solid three-phase reactor, which is mainly used to mix and stir the gas phase, solid phase and liquid phase raw materials inside the reactor.

[0003] Currently, the common gas-liquid-solid three-phase reactor stirring device is mainly composed of a stirring motor, a stirring shaft and a stirring blade. When in use, the stirring motor drives the stirring shaft to rotate so that the stirring blade rotates in the reactor body, thereby mixing and stirring the gas phase, solid phase and liquid phase raw materials in the reactor body.

[0004] However, most of the gas-liquid-solid three-phase reactor stirring devices in the prior art do not have the material shearing function and cannot perform shear mixing processing on the solid raw materials with larger volume or the liquid raw materials with higher viscosity in the reactor body. The larger solid raw materials or the liquid raw materials with higher viscosity will slow down the mixing efficiency of the gas-liquid-solid three-phase raw materials, resulting in poor stirring efficiency and sufficiency of the gas-liquid-solid three-phase reactor stirring device.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a gas-liquid-solid three-phase reactor stirring device. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, a gas-liquid-solid three-phase reaction kettle stirring device in one embodiment of the utility model includes: a kettle body 1, a shearing stirring mechanism 2, and a material turning and mixing mechanism 3.

[0031] like Figure 5As shown, a kettle cover 101 is fixedly mounted on the kettle body 1, and the kettle cover 101 cooperates with the kettle body 1 to form a mixing reaction cavity. The mixing reaction cavity provides a mixing reaction space for gas phase, liquid phase and solid phase raw materials.

[0032] like Figures 1 to 5 As shown, an air inlet pipe 102 is arranged in the kettle body 1. The gas phase raw materials to be mixed are transported through the air inlet pipe 102.

[0033] like Figure 1 As shown, one end of the air inlet pipe 102 located in the kettle body 1 is fixedly connected to the air distribution pipe 103. The gaseous raw material transported by the air inlet pipe 102 is guided and transported through the air distribution pipe 103.

[0034] Specifically, the air distribution pipe 103 is arranged below the material turning blade 302. By arranging the air distribution pipe 103 below the material turning blade 302, the material turning blade 302 can shear and assist in stirring and mixing the gas phase raw material discharged from the aeration element 104 to a certain extent.

[0035] like Figure 1 As shown, multiple groups of evenly distributed aeration elements 104 are fixedly connected below the air distribution pipe 103. The aeration elements 104 are used to transport and guide the gaseous raw materials transported in the air distribution pipe 103. At the same time, the aeration elements 104 are arranged below the air distribution pipe 103 to reduce the risk of blockage of the aeration elements 104.

[0036] like Figure 5 As shown, an exhaust pipe 105 is fixedly connected to one side of the kettle cover 101, and the exhaust pipe 105 is connected to the mixed reaction cavity. The air in the mixed reaction cavity is discharged through the exhaust pipe 105, so as to ensure the air pressure balance in the mixed reaction cavity.

[0037] like Figures 1 to 3 As shown, the shearing stirring mechanism 2 is rotatably assembled in the kettle body 1, and the shearing stirring mechanism 2 includes an active stirring shaft 201, which is rotatably assembled in the kettle body 1. The active stirring shaft 201 plays the role of assembling, fixing and rotating driving the slitting blade 202 and the stirring blade 209.

[0038] like Figure 1 As shown, a stirring motor 205 is fixedly mounted above the kettle cover 101, and the output shaft of the stirring motor 205 is drivingly connected to the active stirring shaft 201. The stirring motor 205 provides power, and the active stirring shaft 201 is driven to rotate by controlling the operation of the stirring motor 205, so as to facilitate mixing and stirring the raw materials in the kettle body 1.

[0039] like Figures 1 to 3As shown, multiple groups of evenly distributed cutting blades 202 are fixedly mounted on the outer side of the active stirring shaft 201. The multiple groups of cutting blades 202 rotate to shear and assist in mixing the solid raw materials with larger volume or the liquid raw materials with higher viscosity in the kettle body 1.

[0040] like Figures 1 to 3 As shown, both sides of the active stirring shaft 201 are rotatably mounted with a driven stirring shaft 203. The driven stirring shaft 203 plays the role of assembling, fixing and rotating the double-toothed slitting blade 204 and the mixing blade 210.

[0041] like Figures 1 to 3 As shown, multiple sets of evenly distributed double-toothed slitting blades 204 are fixedly mounted on the outer side of the driven stirring shaft 203, and the multiple sets of double-toothed slitting blades 204 are arranged in cooperation with the slitting blade 202. The multiple sets of double-toothed slitting blades 204 and the slitting blade 202 cooperate with each other to shear and assist in mixing the solid raw materials with a larger volume or the liquid raw materials with a higher viscosity in the kettle body 1.

[0042] like Figure 1 to Figure 2 As shown, a gear box 206 is fixedly mounted on the top of the kettle body 1, and the gear box 206 is fixedly connected to the inner wall of the kettle cover 101, and the active stirring shaft 201 and a pair of driven stirring shafts 203 are both rotatably connected to the gear box 206. The gear box 206 is used to assemble and limit the active stirring shaft 201 and the pair of driven stirring shafts 203. At the same time, the gear box 206 serves as a closed operating space for the driven gear 207 and the transmission gear 208, thereby reducing the adverse effects of gas phase, liquid phase or solid phase raw materials on the operation of the driven gear 207 and the transmission gear 208.

[0043] like Figure 3 As shown, one end of a pair of driven stirring shafts 203 located in the gear box 206 is fixedly connected with a driven gear 207. The driven stirring shafts 203 are driven to rotate by driving the driven gear 207.

[0044] like Figure 3 As shown, a transmission gear 208 is meshed between a pair of driven gears 207, and the transmission gear 208 is sleeved on the outer side of the active stirring shaft 201. The transmission gear 208 plays a role in transmitting the power of the active stirring shaft 201. Through the mutual meshing of the driven gear 207 and the transmission gear 208, the pair of driven stirring shafts 203 can rotate in the opposite direction to the active stirring shaft 201.

[0045] like Figures 2 to 3As shown, multiple groups of stirring blades 209 are fixedly mounted on the outer side of the active stirring shaft 201, and the multiple groups of stirring blades 209 are staggered with the slitting blades 202. The gas phase, liquid phase and solid phase raw materials in the kettle body 1 are stirred and mixed by the multiple groups of stirring blades 209 rotating with the rotation of the active stirring shaft 201.

[0046] like Figures 2 to 3 As shown, a pair of driven stirring shafts 203 are fixedly equipped with multiple sets of mixing blades 210 on the outside, and the multiple sets of mixing blades 210 are staggered with the double-toothed cutting blades 204. The multiple sets of mixing blades 210 rotate along with the rotation of the driven stirring shafts 203 to assist in stirring and mixing the gas phase, liquid phase and solid phase raw materials in the kettle body 1.

[0047] Specifically, the multi-component cutting blade 202, the double-toothed cutting blade 204, the stirring blade 209 and the mixing blade 210 can be tilted, which can not only facilitate shearing of the gas phase raw materials, but also generate turbulence in the raw materials in the mixed reaction cavity during the stirring process, thereby improving the mixing effect of the raw materials in the mixed reaction cavity.

[0048] like Figures 2 to 4 As shown, the material turning and mixing mechanism 3 is rotatably assembled in the kettle body 1, and the material turning and mixing mechanism 3 includes a pair of material turning shafts 301, which are rotatably assembled below the active stirring shaft 201. The pair of material turning shafts 301 play the role of assembling, fixing and rotating driving the multiple groups of material turning blades 302.

[0049] like Figures 2 to 4 As shown, the outer sides of a pair of material turning shafts 301 are fixedly equipped with multiple groups of evenly distributed material turning blades 302. The multiple groups of material turning blades 302 rotate to turn over the solid raw materials with a large volume or the liquid raw materials with a high viscosity deposited at the bottom of the kettle body 1, so that the double-toothed slitting blade 204 and the slitting blade 202 can fully shear the solid raw materials with a large volume or the liquid raw materials with a high viscosity at the bottom.

[0050] like Figures 2 to 4 As shown, a transmission control box 303 is rotatably mounted between a pair of material turning shafts 301, and the active stirring shaft 201 is rotatably connected to the transmission control box 303. The transmission control box 303 plays the role of assembling and limiting the pair of material turning shafts 301.

[0051] like Figures 2 to 4 As shown, the opposite sides of a pair of turning shafts 301 are rotatably connected with an assembly frame 304, and the assembly frame 304 is fixedly connected to the inner wall of the kettle body 1. The turning shaft 301 is supported and limited by the assembly frame 304, thereby improving the running stability of the turning shaft 301.

[0052] like Figures 2 to 4As shown, one end of the active stirring shaft 201 located in the transmission control box 303 is fixedly connected with a driving bevel gear 305. The driving bevel gear 305 plays the role of transmitting the power of the active stirring shaft 201.

[0053] like Figures 2 to 4 As shown, both sides of the driving bevel gear 305 are meshed with transmission bevel gears 306, and the transmission bevel gear 306 is fixedly connected to one end of the material turning shaft 301 located in the transmission control box 303. The mutual meshing of the driving bevel gear 305 and the transmission bevel gear 306 allows the material turning shaft 301 to rotate synchronously with the rotation of the active stirring shaft 201.

[0054] During specific use, gaseous, liquid or solid raw materials can be added into the kettle body 1 through the feeding pipe above the kettle cover 101. When the gaseous, liquid or solid raw materials need to be mixed and stirred, the active stirring shaft 201 is driven to rotate by controlling the operation of the stirring motor 205. During the rotation process, the active stirring shaft 201 drives the multi-component cutting blade 202 and the stirring blade 209 to rotate.

[0055] At the same time, a pair of driven stirring shafts 203 can rotate in the opposite direction of the active stirring shaft 201 as the active stirring shaft 201 rotates under the meshing action of the driven gear 207 and the transmission gear 208. The rotation of the pair of driven stirring shafts 203 drives the multiple sets of double-toothed slitting blades 204 and the mixing blades 210 to rotate, and the solid raw materials with a larger volume or the liquid raw materials with a higher viscosity in the kettle body 1 are sheared by the relative movement of the multiple sets of slitting blades 202 and the double-toothed slitting blades 204. The sheared raw materials are mixed and stirred by the rotation of the multiple sets of stirring blades 209 and the mixing blades 210.

[0056] In addition, during the rotation of the active stirring shaft 201, the turning shaft 301 rotates along with the rotation of the active stirring shaft 201 under the meshing action of the driving bevel gear 305 and the transmission bevel gear 306. The rotation of the turning shaft 301 drives multiple groups of turning blades 302 to rotate at the bottom of the kettle body 1, thereby turning the raw materials deposited at the bottom of the kettle body 1. This can not only improve the shearing effect of the larger solid-phase raw materials or the higher viscosity liquid-phase raw materials in the kettle body 1, but also assist in stirring and mixing the raw materials in the kettle body 1, thereby improving the stirring efficiency and sufficiency of the gas-liquid-solid three-phase reactor stirring device.
