Description
Technical Field
[0001] This utility model relates to the field of enamel-lined reactor technology, and in particular to the stirring mechanism of an enamel-lined reactor. Background Technology
[0002] Enameled reactors, as a type of corrosion-resistant and high-temperature-resistant reaction equipment, are widely used in industries such as chemical, pharmaceutical, and food. Their stirring mechanism is the core component that ensures the full reaction of materials and improves product quality.
[0003] Currently, in existing enamel-lined reactors, the stirring height of the stirring shaft is mostly fixed and cannot be adjusted according to actual production needs. This fixed-height stirring method easily creates stirring blind zones between adjacent stirring blades in the vertical direction, preventing sufficient mixing. This leads to differences in the degree of reaction within the reactor, affecting not only the overall stirring effect but also potentially reducing the quality stability of the final product, making it difficult to meet the requirements of industrial production for uniform material mixing.
[0004] Therefore, a stirring mechanism for an enamel-lined reactor is provided to address the aforementioned issues. Utility Model Content
[0005] This invention provides a stirring mechanism for an enamel-lined reactor to solve the technical problem of the lack of height adjustment design for the stirring shaft.
[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:
[0007] This utility model provides a stirring mechanism for an enamel-lined reactor, including a base fixed to the top of the reactor; and a stirring shaft, wherein the portion of the stirring shaft located inside the reactor is fixed with multiple blades, and the multiple blades are distributed at equal intervals along the vertical direction.
[0008] A protective shell is fixed to the top of the base, and a transmission part is provided inside the protective shell. The transmission part is connected to a motor fixed to the outside of the protective shell. The transmission part is connected to a stirring shaft. The motor drives the transmission part, which in turn drives the stirring shaft to rotate.
[0009] The protective shell is equipped with a lifting mechanism, which is used to drive the stirring shaft to move up and down.
[0010] The protective shell is provided with a lubrication mechanism for lubricating the transmission part. The transmission part includes a sleeve shaft and a connecting shaft, both of which are rotatably mounted inside the protective shell. A first bevel gear and a second bevel gear are respectively fixedly sleeved on the sleeve shaft and the connecting shaft, and the first bevel gear meshes with the second bevel gear. The end of the connecting shaft is fixed to the output shaft of the motor. A square shaft is fixed to the top of the stirring shaft, and a square groove is formed at the center of the sleeve shaft. The square shaft is connected to the square groove. The lifting mechanism includes a telescopic component. The telescopic component is fixedly mounted on the outer wall of the protective shell. A top plate is fixed to the output end of the telescopic component. A rotating shaft is rotatably mounted in the middle of the top plate, and the bottom end of the rotating shaft is fixed to the square shaft.
[0011] Preferably, a guide sleeve is fixed inside the base, and the stirring shaft is connected to the guide sleeve.
[0012] Preferably, the lubrication mechanism is located below the top plate; the lubrication mechanism includes a cylinder fixedly installed on the top of the protective shell; a piston is fitted inside the cylinder, and a movable column is fixed on the top of the piston. The movable column is slidably fitted with a guide hole opened on the top of the cylinder, and a top plate is fixed on the top of the movable column. The top plate is elastically connected to the top of the cylinder by a spring. A first one-way valve and a second one-way valve are fixedly installed at the bottom of the cylinder. The first one-way valve and the second one-way valve are respectively connected to an oil outlet pipe and an oil inlet pipe.
[0013] Preferably, a nozzle is installed at the bottom end of the oil outlet pipe, and the nozzle is located at the top of the second bevel gear.
[0014] Preferably, the spring is sleeved on the movable column, and the two ends of the spring abut against the bottom surface of the top plate and the top surface of the cylinder, respectively.
[0015] Preferably, an oil storage tank is provided at the bottom of the protective shell, and the bottom end of the oil inlet pipe extends into the oil storage tank.
[0016] Preferably, the protective shell has a side opening on one side, and a sealing plug is installed on the side opening.
[0017] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0018] The positive and progressive effects of this utility model are as follows:
[0019] The stirring mechanism of the enamel-lined reactor mentioned above can drive the stirring shaft to move up and down by setting a lifting mechanism on the protective shell, thereby changing the height position of the stirring shaft and its blades inside the reactor. This design can avoid the problem of insufficient stirring of materials between adjacent blades in the vertical direction, significantly improve the stirring effect of materials, and ensure the sufficiency and consistency of material reaction.

Furthermore, the lubrication mechanism does not need to be equipped with an independent power drive component. Instead, it uses the lifting mechanism to drive the top plate to move up and down, pushing the top plate of the lubrication mechanism and thus providing power for the lubrication process, without the need for manual operation and control.

[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0030] like Figures 1-6As shown, the stirring mechanism of the enamel-lined reactor includes a base 4 fixed to the top of the reactor 1; it also includes a stirring shaft 2, the portion of the stirring shaft 2 located inside the reactor 1 having multiple blades 3 fixed thereon, and the multiple blades 3 being distributed at equal intervals along the vertical direction.
[0031] The top of the base 4 is fixed with a protective shell 5. A transmission part 9 is provided inside the protective shell 5 and the transmission part 9 is connected to a motor 7 fixed to the outside of the protective shell 5. The transmission part 9 is connected to the stirring shaft 2. The motor 7 drives the transmission part 9, which in turn drives the stirring shaft 2 to rotate.
[0032] The protective shell 5 is provided with a lifting mechanism 8, which is used to drive the stirring shaft 2 to move up and down.
[0033] The protective shell 5 is provided with a lubrication mechanism 10, which is used to lubricate the transmission part 9.
[0034] When the reactor 1 is processing materials, the transmission unit 9 is driven by the motor 7, which in turn drives the stirring shaft 2 to rotate. The stirring shaft 2 stirs the materials through the blades 3 on it. During the above process, the lifting mechanism 8 drives the stirring shaft 2 to move up and down, changing the height position of the stirring shaft 2 and its blades 3 in the reactor 1, which facilitates stirring at different height positions in the reactor 1 and improves the stirring effect.
[0035] The lubrication mechanism 10 can lubricate the transmission part 9, reducing wear on the transmission part 9 during continuous operation.
[0036] like Figure 2 As shown, a guide sleeve 6 is fixed inside the base 4, and the stirring shaft 2 is connected to the guide sleeve 6.
[0037] The guide sleeve 6 provides guidance and limit for the up and down movement of the stirring shaft 2. The stirring shaft 2 is cylindrical, and the inner ring of the guide sleeve 6 is circular. This design will not affect the rotation of the stirring shaft 2.
[0038] In practical implementation, the inner ring of the guide sleeve 6 is equipped with balls, which roll and rub against the stirring shaft 2 to reduce the frictional resistance during the up-and-down movement and rotation of the stirring shaft 2.
[0039] like Figure 3 As shown, the transmission part 9 includes a sleeve shaft 901 and a connecting shaft 904. Both the sleeve shaft 901 and the connecting shaft 904 are rotatably mounted inside the protective shell 5. A first bevel gear 902 and a second bevel gear 903 are respectively fixedly sleeved on the sleeve shaft 901 and the connecting shaft 904, and the first bevel gear 902 meshes with the second bevel gear 903. The end of the connecting shaft 904 is fixed to the output shaft of the motor 7.
[0040] like Figures 2-4 As shown, a square shaft 201 is fixed at the top of the stirring shaft 2, and a square groove is provided at the center of the sleeve shaft 901. The square shaft 201 is connected to the square groove.
[0041] When the motor 7 drives the connecting shaft 904 and the second bevel gear 903 to rotate together, the first bevel gear 902 and the sleeve shaft 901 rotate through the meshing transmission between the second bevel gear 903 and the first bevel gear 902. The sleeve shaft 901 drives the square shaft 201 and the stirring shaft 2 to rotate together, thereby driving the stirring shaft 2.
[0042] The stirring shaft 2 is connected to the square hole on the sleeve shaft 901 through the square shaft 201. When the stirring shaft 2 moves up and down, the square shaft 201 and the square hole slide together and always maintain a cooperative connection. When the stirring shaft 2 is adjusted to any height, it will be driven by the motor 7 and the transmission part 9 to make the stirring shaft 2 rotate.
[0043] like Figure 2 As shown, the lifting mechanism 8 includes a telescopic component 801; the telescopic component 801 is fixedly installed on the outer side wall of the protective shell 5, and a top plate 802 is fixed to the output end of the telescopic component 801. A rotating shaft 803 is rotatably installed in the middle of the top plate 802, and the bottom end of the rotating shaft 803 is fixed to the square shaft 201.
[0044] The telescopic component 801 is a pneumatic or hydraulic cylinder. The telescopic component 801 extends and retracts, causing the top plate 802 to move up and down. The top plate 802 then drives the rotating shaft 803, square shaft 201, and stirring shaft 2 below it to move up and down together, thereby adjusting the height of the stirring shaft 2 to stir materials at different heights and ensure the stirring effect.
[0045] The rotating shaft 803, which is fixed to the top of the square shaft 201, is rotatably connected to the top plate 802. When the stirring shaft 2 and the square shaft 201 rotate together, the rotating shaft 803 rotates with the stirring shaft 2. Through the above design, the height of the stirring shaft 2 can be adjusted without affecting the rotation of the stirring shaft 2.
[0046] like Figures 3-6As shown, the lubrication mechanism 10 is located below the top plate 802; the lubrication mechanism 10 includes a cylinder 1001 fixedly installed on the top of the protective shell 5; a piston 1010 is fitted inside the cylinder 1001, and a movable column 1002 is fixed on the top of the piston 1010. The movable column 1002 is slidably fitted with a guide hole opened on the top of the cylinder 1001, and a top plate 1003 is fixed on the top of the movable column 1002. The top plate 1003 is elastically connected to the top of the cylinder 1001 by a spring 1004. A first one-way valve 1008 and a second one-way valve 1009 are fixedly installed at the bottom of the cylinder 1001. The first one-way valve 1008 and the second one-way valve 1009 are respectively connected to an oil outlet pipe 1005 and an oil inlet pipe 1007.
[0047] The bottom end of the oil outlet pipe 1005 is equipped with a nozzle 1006, and the nozzle 1006 is located on top of the second bevel gear 903.
[0048] The spring 1004 is sleeved on the movable column 1002, and the two ends of the spring 1004 abut against the bottom surface of the top plate 1003 and the top surface of the cylinder 1001, respectively.
[0049] An oil storage tank is provided inside the bottom of the protective shell 5, and the bottom end of the oil inlet pipe 1007 extends into the oil storage tank.
[0050] like Figures 3-4 As shown, at this time, the telescopic component 801 in the lifting mechanism 8 is in a retracted state, and the stirring shaft 2 is lowered to the lowest position. The top plate 802 of the lifting mechanism 8 presses down on the top plate 1003, so that the top plate 1003, the movable column 1002 and the piston 1010 are pushed to the lowest position, while the spring 1004 is in a compressed state.
[0051] The lifting mechanism 8 drives the stirring shaft 2 and the top plate 802 to move upward together, separating the top plate 802 from the top plate 1003. The spring 1004 in the lubrication mechanism 10 pushes the top plate 1003, the movable column 1002, and the piston 1010 to move upward together, causing the cylinder 1001 to draw in oil. The lubricating oil in the oil storage tank at the bottom of the protective shell 5 enters the cylinder 1001 through the oil inlet pipe 1007 and the second one-way valve 1009. Subsequently, the lifting mechanism 8 drives the stirring shaft 2 and the top plate 802 to move downward together. The top plate 802 pushes the top plate 1003, and the top plate 1003, the movable column 1002, and the piston 1010 move downward together, compressing the spring 1004. The piston 1010 pushes the oil in the cylinder 1001, causing the oil to enter the oil outlet pipe 1005 through the first one-way valve 1008, and then spray out from the nozzle 1006 to provide lubricating oil for the second bevel gear 903.
[0052] The second bevel gear 903 rotates and meshes with the first bevel gear 902, allowing oil to enter between them for lubrication. Excess oil on the second bevel gear 903 drips into the oil reservoir, preventing waste.
[0053] Through the above design, the lubrication mechanism 10 automatically provides lubrication for the first bevel gear 902 and the second bevel gear 903 in the transmission part 9. The lubrication mechanism 10 drives the top plate 802 to move up and down with the help of the lifting mechanism 8, and pushes the top plate 1003 to provide power, thereby achieving lubrication. The lubrication mechanism 10 itself does not need to be driven by an additional power source.
[0054] like Figure 4 As shown, a side opening is provided on one side of the protective shell 5, and a sealing plug 501 is installed on the side opening.
[0055] The side port is used to add oil to the protective shell 5 or to remove oil through a suction tube, so as to replace the oil in the oil reservoir at the bottom of the protective shell 5; after the oil is replaced, the side port is sealed with a sealing plug 501.
[0056] This utility model is not limited to the above-described embodiments. Any changes made to its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
