[0002] "Hydrocarbons" are a series of substances composed of carbon and hydrogen elements mixed in different proportions. The lighter part is called light hydrocarbons. The main component of natural gas is C1 methane, containing a small amount of C2 ethane. The main components of liquefied petroleum gas are C3 propane and C4 butane. They are gaseous at room temperature and pressure and are called gaseous light hydrocarbons. When converting normal alkanes to isoalkanes, the reaction needs to be carried out under certain reaction conditions and in the presence of a catalyst. When preparing the catalyst used to convert normal alkanes to isoalkanes, mixing equipment is required to mix deionized water, a phosphorus source, and other auxiliary materials.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figures 1 to 6 As shown, the catalyst mixing device for light hydrocarbon isomerization of the present invention comprises a mixing tank body 1, a bottom plate 5 and a swing assembly 6. The mixing tank body 1 is placed on the bottom plate 5, and the swing assembly 6 is placed between the mixing tank body 1 and the bottom plate 5 to connect the mixing tank body 1 and the bottom plate 5.

[0031] A stirring assembly is provided on the mixing tank 1, such as Figure 5 As shown, the stirring assembly includes a rotating rod 15 and a first power device 10. The first power device 10 is a reduction motor. The first power device 10 is placed on the outer periphery of the mixing tank body 1 in the longitudinal direction. The output end of the first power device 10 is fixedly connected to one end of the rotating rod 15. The other end of the rotating rod 15 is inserted into the mixing tank body 1. A plurality of mixing blades 16 are evenly distributed on the rotating rod 15.

[0032] The swing assembly 6 includes a rotating plate 603, the mixing tank body 1 is fixed to the rotating plate 603, the rotating shaft 601 is extended on both sides of the width direction of the rotating plate 603, the bottom plate 5 is provided with support plates 602 corresponding to the two rotating shafts 601, the rotating shaft 601 is rotatably connected to the support plates 602, a cam 604 is provided between the rear end of the rotating plate 603 and the bottom plate 5, the cam 604 is in contact with the rotating plate 603, and a second power device 11 is provided on the bottom plate 5 corresponding to the cam 604. The second power device 11 is a reduction motor, such as Figure 1 、 Figure 2 and Figure 4 shown.

[0033] The stirring assembly, including the rotating rod 15, the first power device 10, and the evenly distributed mixing blades 16, effectively improves the mixing efficiency of the materials within the mixing tank 1, thereby promoting the isomerization reaction. The second power device 11 in the swing assembly 6 drives the cam 604 to rotate, causing one end of the rotating plate 603 to swing up and down, further improving the mixing efficiency and the mixing effect.

[0034] The bottom plate 5 is provided with a relief groove 7 corresponding to the cam 604. Figure 1 and Figure 4 As shown, the bottom of cam 604 is inserted into a relief groove 7. By designing relief groove 7, direct contact and wear between cam 604 and base plate 5 are reduced, extending the service life of the device. Furthermore, relief groove 7 acts as a buffer structure, reducing the impact of cam 604 on base plate 5 during swinging, thereby reducing noise.

[0035] A support block 9 is provided on the rotating plate 603 corresponding to the mixing tank body 1. The shape of the contact surface between the support block 9 and the mixing tank body 1 is adapted to the shape of the mixing tank body 1. Figure 3 As shown, the support block 9 conforms to the shape of the mixing tank 1, providing better support, increasing the stability of the entire device and reducing vibration and displacement during operation. Furthermore, the conforming support block 9 more evenly distributes the weight of the mixing tank 1 and the forces generated during operation, avoiding excessive localized stress concentration.

[0036] Four legs 8 are evenly distributed across the bottom of the base plate 5. These legs 8 provide more even support, increasing the stability of the entire device, especially when under load. Furthermore, during operation, the legs 8 help reduce vibration, maintaining smooth operation. Furthermore, the legs 8 adapt to uneven or non-uniform ground conditions, ensuring device stability.

[0037] The top of the mixing tank 1 is provided with a liquid inlet and a sealing cover 2. Figure 3As shown, a sealing plug 12 is provided at the bottom of the sealing cap 2. The sealing cap 2 and the sealing plug 12 provide a dual sealing mechanism, ensuring that liquid does not leak from the liquid inlet during the mixing process, protecting the working environment and the safety of the operator. Furthermore, the provision of the sealing cap 2 simplifies the opening and closing of the liquid inlet, improving work efficiency.

[0038] The outer diameter of the sealing plug 12 is designed to form an interference fit with the inner diameter of the liquid inlet. This interference fit ensures close contact between the sealing plug 12 and the liquid inlet, forming an effective seal and preventing liquid or gas leakage, thereby improving overall sealing performance. Furthermore, under vibration or operating pressure, the interference fit increases friction between the sealing plug 12 and the liquid inlet, preventing the sealing plug 12 from loosening and ensuring long-term sealing reliability.

[0039] A handle 13 is provided on the top of the sealing cover 2. Figure 3 As shown, the handle 13 provides a convenient place to hold and operate, making it easier for the user to open and close the sealing cover 2. At the same time, in an emergency situation where the sealing cover 2 needs to be opened or closed quickly, the handle 13 can serve as a clear holding point, reducing operation time and thus improving safety.

[0040] A transparent observation window is provided on the sealing cover 2 so that the operator can observe the situation of the material in the tank without opening the sealing cover 2.

[0041] The sealing cover 2 is provided with a plurality of exhaust holes 14, such as Figure 3 As shown, vent 14 is connected to mixing tank 1. Vent 14 regulates the internal pressure of the mixing tank, preventing excessive pressure increases or decreases due to material reactions or temperature changes during operation, thereby protecting the tank from pressure damage. Furthermore, when the internal pressure of the tank increases, vent 14 acts as a safety valve, preventing overflow or splashing of the liquid in the tank due to excessive pressure, thereby ensuring safe operation.

[0042] A discharge pipe 4 is provided at the lower portion of one end of the mixing tank 1 away from the first power device 10. Figure 3 As shown, a discharge pipe 4 is connected to the mixing tank body 1 and a valve 3 is provided on the discharge pipe 4. The design of the discharge pipe 4 facilitates cleaning and maintenance of the interior of the tank body, as it makes it easier to remove materials remaining at the bottom of the tank. The valve 3 can control the discharge of materials, allowing the operator to open or close the discharge process at any time as needed. When the discharge operation is not in progress, closing the valve 3 can prevent material leakage, ensuring a clean production environment and full utilization of materials. Secondly, by controlling the opening and closing of the valve 3, the accidental ejection of materials due to excessive pressure in the tank can be prevented, thereby improving the safety of the operation.

[0043] Working process: First, pull the sealing cover 2 upward to separate the surface of the sealing plug 12 from the mixing tank body 1, then add the catalyst preparation raw materials used in the isomerization of light hydrocarbons into the mixing tank body 1, then start the first power device 10, the first power device 10 rotates to drive the rotating rod 15 and the mixing blades 16 to rotate, thereby mixing the raw materials inside the mixing tank body 1, and then start the second power device 11. The rotation of the second power device 11 can drive the cam 604 to rotate through the output shaft, and the rotation of the cam 604 can make the rotating plate 603 and the cam One end of the rotating plate 604 abuts against it and swings up and down. At this time, the other end of the rotating plate 603 is rotatably connected to the support plate 602 through the rotating shaft 601, so that the rotating plate 603 can drive the mixing tank body 1 to swing up and down around the rotating shaft 601. At this time, the raw materials inside the mixing tank body 1 can be shaken back and forth, and the rotation of the rotating rod 15 and the mixing blades 16 are combined to stir and mix the raw materials inside the mixing tank body 1, thereby improving the mixing efficiency of the light hydrocarbon isomerization catalyst. By opening the valve 3, the light hydrocarbon isomerization catalyst mixed inside the mixing tank body 1 can be discharged through the discharge pipe 4.

[0044] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
