Description

Technical Field

[0001] The present invention relates to the technical field of chemical refrigeration, and more specifically to a chemical raw material refrigeration device for chemical industry. Background Art

[0002] Chemical process refers to chemical technology or chemical production technology, which is the method and process of converting raw materials into products mainly through chemical reactions, including all measures to achieve this transformation. In order to make the raw materials meet the state and specifications required for chemical reactions, different raw materials need to undergo various pretreatments such as purification, concentration, mixing, emulsification or crushing according to specific circumstances. The pretreated raw materials react under certain temperature, pressure and other conditions to achieve the required reaction conversion rate and yield. Through chemical reactions, the target product or its mixture is obtained. The mixture obtained by the chemical reaction is separated, and by-products or impurities are removed to obtain products that meet the composition specifications. When using or storing chemical raw materials today, some chemical raw materials are in a fluid state, and the chemical raw materials need to be cooled first, and then the cooled chemical raw materials can be used and collected. Currently, the chemical raw materials are directly cooled by contacting with low-temperature inert gas, which is a slow cooling method, and thus the overall production efficiency is slow; When chemical raw materials are cooled, gases will evaporate. If the gases are directly discharged into the environment, they will affect the people or the environment around them. If the chemical raw materials are sealed, rapid refrigeration processing cannot be carried out. Summary of the invention

[0027] In the embodiment of the present application, when the rotating shaft 604 rotates, the blade group 605 is driven to rotate. The gas generated by the rotation of the blade group 605 enters the rotating square cylinder 608 through the conical cylinder 601, and enters the stirring mechanism 7 through the rotating square cylinder 608, so that the chemical raw materials in the cooling cylinder 2 can be refrigerated, and the upper part of the rotating shaft 604 is connected to the square connecting rod 609, and the square connecting rod 609 is connected to the rotating square cylinder 608 through the sealing plate 610. The rotating shaft 604 is connected to the rotating square cylinder 608 through the connecting bracket 606 and the lower connecting plate 607, so that the rotating shaft 604, the rotating square cylinder 608 and the square connecting rod 609 rotate synchronously, the rotating square cylinder 608 will drive the stirring mechanism 7 to rotate, and the stirring mechanism 7 can perform stirring work, and stirring will also improve the refrigeration effect. The sealing plate 610 separates the interior of the rotating square cylinder 608, so that the stirring mechanism 7 below the sealing plate 610 is exhausted, and the exhaust mechanism 8 above the sealing plate 610 is exhausted, and the two will not affect each other.

[0028] Reference Figure 6 , Figure 7 as well as Figure 8 The stirring mechanism 7 includes an outer exhaust cylinder 701 fixedly connected to the rotating square cylinder 608, the inner exhaust cylinder 702 is movably connected inside the outer exhaust cylinder 701, the side of the inner exhaust cylinder 702 away from the rotating square cylinder 608 is fixedly connected to a magnetic plate 706, the side of the magnetic plate 706 away from the inner exhaust cylinder 702 is provided with an electromagnet 707, the side of the electromagnet 707 is fixedly connected to the inside of the outer exhaust cylinder 701, the magnetic plate 706 is in contact with the electromagnet 707, the exhaust holes in the inner exhaust cylinder 702 and the exhaust holes in the outer exhaust cylinder 701 are staggered, the top and bottom ends of the side of the inner exhaust cylinder 702 away from the magnetic plate 706 are fixedly connected to a movable plate 703, and a limiting hole is provided inside the movable plate 703 A fixing rod 704 is movably connected in the limiting hole of the movable plate 703, and a supporting spring 705 is sleeved on the side of the fixing rod 704. The movable plate 703 and the fixing rod 704 are both located in the rotating square cylinder 608, one side of the fixing rod 704 is fixedly connected to the inner side of the rotating square cylinder 608, and the other side of the fixing rod 704 is fixedly connected to the side of the square connecting rod 609. The supporting spring 705 is located between the square connecting rod 609 and the movable plate 703. A avoiding hole for the movement of the inner exhaust cylinder 702 is provided on the side of the rotating square cylinder 608. When the electromagnet 707 is energized to make the inner exhaust cylinder 702 move toward the square connecting rod 609, the exhaust hole in the inner exhaust cylinder 702 is connected with the exhaust hole in the outer exhaust cylinder 701.

[0029] In the embodiment of the present application, the low-temperature inert gas entering into the rotating square cylinder 608 will enter into the outer exhaust cylinder 701. When the electromagnet 707 is not energized, the exhaust holes in the inner exhaust cylinder 702 and the exhaust holes in the outer exhaust cylinder 701 are staggered with each other, and the gas cannot be discharged, and the chemical raw materials in the cooling cylinder 2 cannot enter into the outer exhaust cylinder 701. At this time, the chemical raw materials can be stored or stirred. When the electromagnet 707 is energized, the inner exhaust cylinder 702 moves toward the square connecting rod 609, and the exhaust holes in the inner exhaust cylinder 702 are connected with the exhaust holes in the outer exhaust cylinder 701, so that the low-temperature inert gas can be discharged. The warm inert gas is discharged into the cooling cylinder 2 to refrigerate the chemical raw materials. The present application can freely select the working state according to different situations. In addition, it should be noted that the four sides of the square connecting rod 609 are connected to the fixed rod 704, and the four sides of the rotating square cylinder 608 are also provided with an external exhaust cylinder 701. The square connecting rod 609 has the same structure as the four sides of the rotating square cylinder 608. The present application uses inert gas to be delivered into the rotating square cylinder 608. The inert gas can avoid reacting with the chemical raw materials. The inert gas of the present application only plays a role of heat exchange, and the inert gas can be selected according to the type of chemical raw materials.

[0030] Reference Figure 2 , Figure 5 and Fig. 9 The exhaust mechanism 8 includes an upper connecting plate 801 fixedly connected to the top of the rotating square cylinder 608, a vacuum cylinder 802 is fixedly connected to the top of the side of the rotating square cylinder 608, a gas hole is opened at the bottom of the vacuum cylinder 802, the upper connecting plate 801 rotates in the sealing cover plate 3, and the upper connecting plate 801 and the sealing cover plate 3 are in a sealed state, a sealing cone cylinder 803 is fixedly connected to the top of the sealing cover plate 3, the sealing cone cylinder 803 covers and seals the upper connecting plate 801, a gas main pipe 804 is fixedly connected to the top of the sealing cone cylinder 803, a reversing valve 805 is fixedly connected to the side of the gas main pipe 804 away from the sealing cone cylinder 803, the two ends of the reversing valve 805 away from the side of the gas main pipe 804 are respectively fixedly connected to the first branch pipe 806 and the second branch pipe 807, and the side of the first branch pipe 806 is fixedly connected to the vacuum pump 808.

[0031] In the embodiment of the present application, the gas in the cooling cylinder 2 will enter the vacuum cylinder 802 and the sealing cone cylinder 803 through the gas hole below the vacuum cylinder 802. After the gas in the sealing cone cylinder 803 passes through the gas main pipe 804, it can be controlled by the reversing valve 805 to be discharged from the first branch pipe 806 or the second branch pipe 807. When less inert gas is precipitated, it can be discharged through the second branch pipe 807, and the vacuum pump 808 does not need to be started, which has the effect of energy saving. When more inert gas is precipitated or the chemical raw materials themselves produce more gas, the reversing valve 805 controls the gas main pipe 804 to be connected with the first branch pipe 806. At this time, the vacuum pump 808 will evacuate gas to quickly extract the gas to ensure the stability of the air pressure in the cooling cylinder 2 The working principle of the present invention is as follows: the chemical raw materials to be cooled are added into the cooling cylinder 2 through the inflow pipe 4. After the chemical raw materials are added, the servo motor 603 is started to drive the rotating shaft 604 to rotate. When the rotating shaft 604 rotates, it drives the blade group 605 to rotate. When the rotating shaft 604 rotates, it drives the connecting bracket 606 and the square connecting rod 609 to rotate synchronously. When the connecting bracket 606 rotates, it drives the rotating square cylinder 608 to rotate through the lower connecting plate 607. When the blade group 605 rotates, gas is generated. The gas generated by the blade group 605 enters the rotating square cylinder 608 through the conical cylinder 601, and enters the stirring mechanism 7 through the rotating square cylinder 608. When the servo motor 603 is started, the electromagnet 707 in the stirring mechanism 7 is energized. After the electromagnet 707 is energized, a magnetic repulsion force is generated between the electromagnet 707 and the magnetic plate 706. Under the action of the magnetic repulsion force, the magnetic plate 706 drives the inner exhaust tube 702 to move. After the inner exhaust tube 702 moves, the exhaust hole in the inner exhaust tube 702 is connected with the exhaust hole in the outer exhaust tube 701, and the movement of the inner exhaust tube 702 drives the moving plate 703 to move and compress the supporting spring 705. When the exhaust hole in the inner exhaust tube 702 is connected with the exhaust hole in the outer exhaust tube 701, the low-temperature inert gas entering the stirring mechanism 7 will be discharged through the outer exhaust tube 701, and the outer exhaust tube 701 and the inner exhaust tube 702 will rotate with the rotating square tube 608 to improve the refrigeration effect. When the chemical raw materials are only stored or stirred in the cooling cylinder 2, the electromagnet 707 is not energized. At this time, there is no magnetic repulsion between the magnetic plate 706 and the electromagnet 707, and the support spring 705 will reset to make the magnetic plate 706 contact the electromagnet 707. At this time, the exhaust holes in the inner exhaust cylinder 702 and the exhaust holes in the outer exhaust cylinder 701 are staggered to prevent the raw materials in the cooling cylinder 2 from entering the outer exhaust cylinder 701. When the servo motor 603 is started, the exhaust holes in the inner exhaust cylinder 702 and the outer exhaust cylinder 701 are staggered. The exhaust holes in the inner exhaust cylinder 702 and the outer exhaust cylinder 701 can be staggered at any time to discharge inert gas and prevent chemical raw materials from entering. When the servo motor 603 is not started, the exhaust holes in the inner exhaust cylinder 702 and the exhaust holes in the outer exhaust cylinder 701 are in a staggered state before the raw materials are added. When the outer exhaust cylinder 701 rotates with the rotating square cylinder 608, the inner exhaust cylinder 702 will also move outward under the action of force, further preventing the inner exhaust cylinder 702 from moving into the rotating square cylinder 608 and connecting the exhaust holes of the two. After the low-temperature inert gas is discharged from the outer exhaust cylinder 701, the low-temperature inert gas enters the chemical raw material. After the chemical raw material is refrigerated, the low-temperature inert gas becomes hot inert gas and precipitates from the chemical raw material. The precipitated gas enters the vacuum cylinder 802 through the gas hole below the vacuum cylinder 802, and enters the sealed cone cylinder 803 through the rotating square cylinder 608 and the upper connecting plate 801. After the gas in the sealed cone cylinder 803 passes through the gas main pipe 804, the reversing valve 805 can be used to control whether it is discharged from the first branch pipe 806 or the second branch pipe 807. When less inert gas is precipitated, it can be discharged through the second branch pipe 807. The vacuum pump 808 does not need to be started, which has an energy-saving effect. When more inert gas is precipitated or the chemical raw material itself produces more gas, the reversing valve 805 controls the gas main pipe 804 to be connected with the first branch pipe 806. At this time, the vacuum pump 808 will evacuate gas to quickly extract the gas to ensure that the air pressure in the cooling cylinder 2 is stable.

[0032] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
