Description

Technical Field

[0002] The reaction tank has the characteristics of high heating or cooling rate, high temperature resistance, corrosion resistance, hygiene, no environmental pollution, no need for boiler automatic heating and easy use. It is widely used in petrochemical industry.

[0003] At present, cooling reaction tanks for petrochemical stirring are of great significance in the processing of petroleum products. Although the cooling reaction tanks used for chemical stirring in the prior art can also meet the needs of petroleum processing technology in daily work, the volume of the reaction tank is a fixed structure, and the amount of petroleum to be reacted each time is not exactly the same, which leads to different heights of the petroleum added each time, and the height of the cooling or stirring mechanism inside the reaction tank is fixed. In this way, when a small amount of petroleum is added for cooling reaction, the lower end of the cooling mechanism or stirring mechanism can cool the added petroleum, while the upper end of the cooling mechanism or stirring mechanism is not filled with petroleum, so the cooling medium inside the cooling mechanism cannot cool the petroleum, thereby reducing the efficiency of the cooling reaction and limiting the effective utilization rate of the cooling medium.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cooling reaction tank for stirring in a petrochemical industry, comprising a stirring barrel 1 and a controller 30. A liquid level gauge 29 is installed on the inner wall of the stirring barrel 1, and the liquid level gauge 29 is electrically connected to the controller 30. A protective cover 2 is installed on the outside of the stirring barrel 1, and a movable sleeve 3 is provided between the stirring barrel 1 and the protective cover 2. Both sides of the movable sleeve 3 are in contact with the stirring barrel 1 and the protective cover 2. A plurality of drainage springs 28 are evenly distributed and spirally wound around the surface of the stirring barrel 1. The two ends of each drainage spring 28 are connected to the protective cover 2 and the movable sleeve 3 through a drainage component 7. The bottom of the side of the protective cover 2 is connected to an air intake component 4, the upper end of the side of the protective cover 2 is connected to a first exhaust pipe 5, and an exhaust component 6 is provided above the movable sleeve 3.

[0035] The air intake assembly 4 includes an air intake pipe 41, one end of which is connected to the protective cover 2. An air intake valve 42 is installed inside the air intake pipe 41. The air intake pipe 41, the air intake valve 42, the exhaust assembly 6 and the first exhaust pipe 5 are interconnected. The air intake valve 42 is electrically connected to the controller 30.

[0036] The exhaust assembly 6 includes an air collecting pipe 63, the interior of which is sheathed with a number of evenly distributed air outlet pipes 62. Both ends of the air outlet pipes 62 pass through an exhaust valve 61, which is electrically connected to the controller 30. The bottom of the air outlet pipe 62 is connected to the exhaust valve 61, which is installed inside the movable sleeve 3. The bottom of the exhaust valve 61 passes through the movable sleeve 3. The movable sleeve 3, the exhaust valve 61, the air outlet pipe 62 and the air collecting pipe 63 are interconnected.

[0037] The drainage assembly 7 includes a plurality of connecting tubes 71, a permeable cotton pad 74 and a drainage rod 75, a water collecting pipe 72 and a water inlet pipe 73. The bottom of the connecting tube 71 is connected to the movable sleeve 3, the top of the connecting tube 71 is connected to the water collecting pipe 72, one end of the water inlet pipe 73 is connected to the water collecting pipe 72, and the other end of the water inlet pipe 73 extends to the outside of the movable sleeve 3. The permeable cotton pad 74 and the drainage rod 75 are sleeved inside the connecting tube 71. The permeable cotton pad 74 is connected to one end of the drainage rod 75. The other end of the drainage rod 75 passes through the movable sleeve 3 or the protective cover 2 and is connected to the drainage spring 28.

[0038] The air inlet valve 42 and the exhaust valve 61 can be used to adjust the air pressure difference between the interior of the cavity and the upper and lower sides of the movable sleeve 3 under the control of the controller 30, so that the position of the movable sleeve 3 can be automatically changed so that the height of the movable sleeve 3 is the same as the height of the oil injected into the mixing barrel 1, and then the surface of the mixing barrel 1 is quickly cooled down with the cooperation of the cooling gas input at the air inlet component 4 and the cooling liquid drained from the surface of the drainage spring 28, thereby effectively improving the cooling efficiency; and the cooling liquid outside the protective cover 2 can be drained to the surface of the drainage spring 28 through the drainage component 7 and flowed along the surface of the mixing barrel 1, and finally flowed out of the protective cover 2 with the cooperation of the drainage component 7 at the bottom of the drainage spring 28. With the cooperation of the drainage spring 28, not only can the cooling liquid flow along the surface of the mixing barrel 1, increasing the contact area between the cooling liquid and the mixing barrel 1 and improving the heat absorption efficiency of the cooling liquid, but also the cooling liquid can spirally move along the drainage spring 28, increasing the contact time of the cooling liquid with the mixing barrel 1.

[0039] like Figure 3 As shown, the inner diameter of the connecting tube 71 is the same as the inner diameter of the movable sleeve 3, the outer diameter of the permeable cotton pad 74 is adapted to the inner diameter of the connecting tube 71, and the outer diameter of the drainage rod 75 is smaller than the inner diameter of the connecting tube 71;

[0040] Several connecting tubes 71 can be connected to the water inlet pipe 73 through the water collecting pipe 72, so that water can be injected into multiple connecting tubes 71 at the same time through a water supply pipeline, so that they can be drained through multiple drainage springs 28 at the same time to improve the cooling efficiency. The penetrating cotton pad 74 can ensure that the cooling liquid inside the connecting tube 71 can be transferred to the surface of the drainage rod 75 and flow to the surface of the drainage spring 28.

[0041] like Figure 5 As shown, a sealing cover 8 is installed on the top of the protective cover 2, the top of the sealing cover 8 is connected to a feed pipe 9, and the bottom of the mixing barrel 1 is connected to a discharge pipe 10. The feed pipe 9, the mixing barrel 1 and the discharge pipe 10 are interconnected.

[0042] like Figure 5 As shown, a transmission rod 12 is installed at the bottom of the inner cavity of the mixing barrel 1 through a positioning assembly 11. A plurality of sliding plates 13 and a return spring 14 are sleeved inside the transmission rod 12. The sliding plates 13 and the return springs 14 are alternately arranged. The bottom of the return spring 14 is connected to the bottom of the inner cavity of the transmission rod 12.

[0043] The sliding plate 13 can be used to evenly separate the multiple return springs 14, leaving gaps between adjacent return springs 14, so that sufficient oil around the adjacent mounting sleeves 17 and the stirring rods 18 can be stirred by the stirring rods 18. At the same time, under the elastic recovery action of the return springs 14, the sliding plate 13 and the slider 16 can drive the mounting sleeves 17 and the stirring rods 18 to move and reset as a whole.

[0044] like Figure 5 As shown, the positioning assembly 11 includes a positioning shaft 111, which is fixedly connected to the mixing barrel 1, a positioning sleeve 112 is sleeved on the upper end of the positioning shaft 111, and a ball 113 is clamped on the top of the positioning shaft 111, and the ball 113 is in contact with the positioning sleeve 112;

[0045] The bottom of the transmission rod 12 can be restricted by the positioning component 11 so that it is connected to the mixing barrel 1, ensuring that the bottom of the transmission rod 12 remains stable when it rotates. At the same time, with the cooperation of the ball 113, the friction strength between the transmission rod 12 and the positioning component 11 can be effectively reduced, which not only reduces the heat generated by friction, but also reduces the consumption of power source by friction.

[0046] like Figure 6 As shown, a slide groove 15 is provided on the side of the transmission rod 12, a slider 16 is clamped inside the slide groove 15, a mounting sleeve 17 is sleeved on the outside of the transmission rod 12, and an agitating rod 18 is mounted on the outside of the mounting sleeve 17. Both ends of the slider 16 pass through the slide groove 15 and are fixedly connected to the sliding plate 13 or the mounting sleeve 17 respectively;

[0047] Through the slide groove 15, the sliding plate 13 inside the transmission rod 12 can be connected to the mounting sleeve 17 outside the transmission rod 12 with the cooperation of the slider 16. At the same time, with the cooperation of the slide groove 15 and the slider 16, the mounting sleeve 17 and the stirring rod 18 as a whole can maintain a synchronous movement effect with the sliding plate 13 and the return spring 14 as a whole.

[0048] like Figure 8As shown, the interior of the transmission rod 12 is sleeved with a pushing assembly 19, and a positioning block 27 is installed inside the transmission rod 12, which is located outside the pushing assembly 19 and at the top of the slide 15. The top of the transmission rod 12 passes through the sealing cover 8 and is fixedly sleeved with a transmission gear 20. The interior of the transmission rod 12 is fixedly sleeved with a positioning block 21 located at the top of the pushing assembly 19, and a rotating plug 22 is sleeved inside the positioning block 21.

[0049] The rotating plug 22 can be installed inside the transmission rod 12 through the positioning block 21 to facilitate the communication between the second exhaust pipe 23 and the transmission rod 12. At the same time, with the cooperation of the positioning block 21 and the rotating plug 22, the transmission rod 12 can be driven to rotate with the cooperation of the transmission gear 20 to avoid the rotation of the transmission rod 12 affecting the second exhaust pipe 23.

[0050] like Figure 4 As shown, the top of the rotary plug 22 is connected to a second exhaust pipe 23, the other end of the second exhaust pipe 23 is connected to the first exhaust pipe 5, a first solenoid valve 24 is installed inside the second exhaust pipe 23, the outside of the second exhaust pipe 23 is connected to a diffuser pipe 25 located between the first solenoid valve 24 and the outlet pipe 62, a second solenoid valve 26 is installed inside the diffuser pipe 25, and both the first solenoid valve 24 and the second solenoid valve 26 are connected to the controller 30 via wireless transmission;

[0051] The gas input by the air intake assembly 4 and after absorbing heat can be guided to the interior of the rotary plug 22 or the air diffusion pipe 25 through the second exhaust pipe 23. Then, under the control of the controller 30, the cooperation of the first solenoid valve 24 and the second solenoid valve 26 can change the flow rate of the gas entering the air diffusion pipe 25 and the interior of the rotary plug 22 through the second exhaust pipe 23.

[0052] like Figure 8 As shown, the pushing assembly 19 includes a pushing sleeve rod 191, a connecting sleeve rod 192 and a pushing rod 193. The pushing sleeve rod 191 is sleeved inside the transmission rod 12, the connecting sleeve rod 192 is sleeved inside the pushing sleeve rod 191, and the pushing rod 193 is sleeved inside the connecting sleeve rod 192. An air storage tank 194 is provided on the top of the pushing rod 193. The bottoms of the inner cavities of the pushing sleeve rod 191 and the connecting sleeve rod 192 are fixedly sleeved with a first limit block 195, and the tops of the outer surfaces of the pushing sleeve rod 191, the connecting sleeve rod 192 and the pushing rod 193 are fixedly sleeved with a second limit block 196.

[0053] The continuously input gas can push the pushing assembly 19 downward under the limitation of the transmission rod 12 through the pushing assembly 19, and with the cooperation of the first limit block 195, the second limit block 196 and the positioning block 27, the overall length of the pushing sleeve rod 191, the connecting sleeve rod 192 and the pushing rod 193 is increased, which ensures that the sliding plate 13 and the return spring 14 are pressed downward as a whole through the pushing assembly 19, and the influence of the slide groove 15 can be avoided through the pushing assembly 19.

[0054] like Figure 8 As shown, the second limit block 196 and the first limit block 195 located between the pushing sleeve rod 191 and the connecting sleeve rod 192 respectively follow the pushing sleeve rod 191 and the connecting sleeve rod 192 to move and contact each other, the second limit block 196 and the first limit block 195 located between the connecting sleeve rod 192 and the pushing rod 193 respectively follow the connecting sleeve rod 192 and the pushing rod 193 to move and contact each other, the second limit block 196 located outside the pushing sleeve rod 191 follows the pushing sleeve rod 191 to move downward and eventually contacts the top of the positioning block 27, the bottom of the pushing rod 193 passes through the connecting sleeve rod 192 and contacts the sliding plate 13, and the air storage tank 194 is connected to the second exhaust pipe 23 through the transmission rod 12;

[0055] The gas storage tank 194 can increase the original amount of gas entering the transmission rod 12, thereby increasing the gas pushing the pushing assembly 19, and can give priority to pushing the pushing rod 193, so that the pushing rod 193 or the connecting sleeve rod 192 is sequentially pulled out from the inside of the connecting sleeve rod 192 or the inside of the pushing sleeve rod 191, and then the pushing assembly 19 is lengthened with the cooperation of the positioning block 27 and the corresponding first limit block 195 and the second limit block 196, so that it pushes the sliding plate 13 downward and squeezes the return spring 14 to increase its elastic recovery performance. At the same time, with the cooperation of the slide groove 15 and the slider 16, the mounting sleeve 17 and the stirring rod 18 can be driven to move downward as a whole, ensuring that multiple mounting sleeves 17 and stirring rods 18 are completely inside the oil to be processed.

[0056] Working principle and usage process:

[0057] The oil to be processed is added to the mixing barrel 1 through the feed pipe 9. After the filling is completed, the level gauge 29 monitors the oil level and transmits the monitoring result to the controller 30 so that it controls the opening degree of the air inlet valve 42 and the exhaust valve 61. Therefore, the cooling gas input between the mixing barrel 1 and the protective cover 2 through the air inlet pipe 41 can be diverted to the upper and lower sides of the movable sleeve 3 under the action of the pressure difference between the upper and lower sides. The movable sleeve 3 is pushed to the same level as the oil. At the same time, the input cooling gas can cool the mixing barrel 1 and remove the heat inside the oil.

[0058] The cooling liquid is input into the water collecting pipe 72 through the water inlet pipe 73, and is dispersed by the water collecting pipe 72 so as to enter the interior of the multiple connecting pipes 71 and penetrate the surface of the drainage rod 75 through the permeable cotton pad 74 under the action of gravity. Then, it continues to flow to the surface of the drainage spring 28 under the action of gravity. Finally, under the cooperation of gravity and the drainage effect of the drainage spring 28, the cooling liquid slowly spirals downward along the drainage spring 28 on the surface of the mixing barrel 1, thereby taking away most of the heat on the surface of the mixing barrel 1, and finally flows to the outside of the protective cover 2 through the bottom of the drainage spring 28 and the drainage component 7 inside the protective cover 2;

[0059] Since cold air is continuously inputted into the air inlet pipe 41, and with the cooperation of the exhaust valve 61 and the air inlet valve 42, the gas which continuously enters and absorbs heat flows into the interior of the second exhaust pipe 23 through the collecting pipe 63 and the air outlet pipe 62, and under the control of the first solenoid valve 24 and the second solenoid valve 26 by the controller 30, the first solenoid valve 24 and the second solenoid valve 26 are opened to the required size, and the flow rate of the first solenoid valve 24 is greater than the flow rate of the second solenoid valve 26, and then the gas which continuously enters the interior of the second exhaust pipe 23 can enter the interior of the transmission rod 12 and the top of the pushing assembly 19 through the first solenoid valve 24, the second exhaust pipe 23 and the rotary plug 22. Since the continuous input of gas will push the pushing assembly 19 downward, The movement of the pressing assembly 19 can increase its elastic recovery performance by squeezing the return spring 14 downward through the sliding plate 13, and the movement of the sliding plate 13 can drive the mounting sleeve 17 and the stirring rod 18 to move downward as a whole under the cooperation of the slide groove 15 and the slider 16, and make the stirring rod 18 completely inside the oil. When the amount of oil increases, the first solenoid valve 24 and the second solenoid valve 26 are controlled to make the flow rate of the first solenoid valve 24 smaller than that of the second solenoid valve 26, and the pushing assembly 19 can be pushed upward through the sliding plate 13 under the elastic recovery action of the return spring 14, and then the gas inside the transmission rod 12 and the top of the pushing assembly 19 is discharged through the rotary plug 22, the second exhaust pipe 23, the first solenoid valve 24, the air diffusion pipe 25 and the second solenoid valve 26.
