Cooling is often required in the production process of chemical raw materials, and some chemical raw materials have high temperature requirements during preparation and production. It is necessary to cool down the production equipment and chemical raw materials. At present, the most common cooling method is to cool the production equipment or chemical raw materials by circulating coolant. That is, chemical cooling equipment achieves the purpose of cooling by indirectly contacting the chemical raw materials with coolant.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0034] like Figures 1 to 6 As shown, the chemical raw material cooling device designed in this invention includes a support column 2, a cooling vessel 3, and a controller 5. The cooling vessel 3 includes a cooling vessel body 17 and a vessel cover 16. The support column 2 is fixed to the bottom of the cooling vessel body 17. The device also includes:
[0035] The feed inlet 10 is located on the top of the vessel lid 16;
[0036] The feed pipe 14 is fixed to the feed inlet 10;
[0037] The discharge port 24 is located at the bottom of the cooling vessel body 17. An electric control valve is provided in the discharge port 24 to control the opening and closing of the discharge port 24.
[0038] Cooling plate 19 is located inside cooling vessel body 17. There is one or more cooling plates 19. A feed port 21 is opened in the cooling plate 19. The feed ports 21 on adjacent cooling plates 19 are staggered. A cavity 20 is opened in the cooling plate 19. An air outlet 26 is opened at the bottom of the cooling plate 19. The cavity 20 is connected to the air outlet 26.
[0039] The belt shaft 7 has one end fixedly connected to the cooling plate 19, and the other end of the belt shaft 7 passes through the cooling vessel body 17. The belt shaft 7 and the cooling vessel body 17 are connected by a bearing at the contact point.
[0040] Motor 4 is located on one side of the cooling vessel body 17 and is fixed to the motor support frame 9. It is controlled by controller 5.
[0041] Pulley 8 is fixed to the output shaft of motor 4;
[0042] Belt 6 is fitted onto belt shaft 7 and pulley 8;
[0043] A rotating shaft 27 is installed at the end of the cooling plate 19 away from the belt shaft 7. One end of the rotating shaft 27 is fixedly connected to the cooling plate 19, and the other end of the rotating shaft 27 away from the belt shaft 7 passes through the cooling vessel body 17. The contact point between the rotating shaft 27 and the cooling vessel body 17 is connected by a bearing.
[0044] Air cooler 1, controlled by controller 5, is located on one side of cooling vessel 3. Air cooler 1 has an air inlet 11 connected to first air supply pipe 12. First air supply pipe is connected to second air supply pipe 13. Second air supply pipe 13 passes through hollow rotating shaft 27 and is connected to cavity 20 of cooling plate 19. Second air supply pipe 13 is rotatably connected to rotating shaft 27.
[0045] Specifically, before the chemical raw materials need to be cooled, the air cooler 1 is first started by the controller 5. The air cooler 1 absorbs external air and cools it. The cooled air is then delivered to the first air supply pipe and the second air supply pipe 13 through the air supply port 11. The cooled air then enters the cavity 20 and enters the cooling vessel 17 through the air outlet 26 to pre-cool the cooling vessel 17 and the cooling plate 19. The pre-cooling time is set according to the volume of the cooling vessel 17. The overall pre-cooling time is controlled to be 20-30 minutes. During the pre-cooling process, the controller 5 controls the electric control valve to close and closes the feed pipe 14 through the sealing plug to maintain the pre-cooling effect.
[0046] Among them, the air cooler 1 is existing technology and will not be discussed in detail here.
[0047] Secondly, after precooling, when the chemical raw material needs to be cooled, the sealing plug is removed from the feed pipe 14, and then the chemical raw material to be cooled is fed into the feed port 10. At the same time, the motor 4 is started by the controller 5. The rotation of the motor 4 drives the pulley 8 to rotate, and the rotation of the pulley 8 drives the belt shaft 7 to rotate through the belt 6, thereby causing the cooling plate 19 to rotate. During the rotation of the cooling plate 19, it can come into contact with the chemical raw material falling from the feed pipe 14. In this process, the agglomerates in the chemical raw material can be homogenized. The homogenized chemical raw material can then fully contact the cooled air. This improves the cooling effect of chemical raw materials. At the same time, when the cooled air enters the cooling vessel 17 through the air outlet 26 and the cooling plate 19 rotates, the rotating cooling plate 19 can cause the cooling air discharged from the air outlet 26 to disperse in the cooling vessel 17. The dispersed cooling air can fully contact the falling chemical raw materials, increasing the contact area between the cooling air and the chemical raw materials, and further improving the cooling effect of the chemical raw materials. After the chemical raw materials are cooled, the electric control valve in the discharge port is opened by the controller 5, and the chemical raw materials are collected at the discharge port 24 and enter the next production process, such as mixing and processing.
[0048] Meanwhile, compared with the existing technology of using water cooling to cool chemical raw materials, the present invention uses cooling air to cool chemical raw materials, which can directly contact the chemical raw materials that need to be cooled, and its cooling effect is better.
[0049] It should be noted that in order for the motor 4 to operate normally, the motor 4 needs to be fixed by the motor support frame 9. The motor support frame 9 is existing technology and will not be described in detail. At the same time, because the material inlets 21 are staggered in this invention, the chemical raw materials falling from the feed pipe can be prevented from falling directly into the discharge outlet 24, which would affect the cooling effect of the chemical raw materials.
[0050] Furthermore, when cooling chemical raw materials, the feed pipe 14 is in the open state, so there is no need to worry about the cooling vessel 17 being damaged due to excessive cooling air pressure and the inability to dissipate heat. When maintenance of the cooling vessel 17 is required, the lid 16 can be opened.
[0051] As a preferred embodiment of the present invention: the upper surface of the cooling plate 19 is provided with an annular groove 22, the distance between adjacent cooling plates 19 is greater than the sum of the radii of the two cooling plates 19, and the annular groove 22 is used to hold chemical raw materials.
[0052] Furthermore, when the chemical raw material falls from the feed pipe 14 onto the cooling plate 19, the cooling plate 19 is provided with an annular groove 22, which can receive the chemical raw material. When the chemical raw material falls onto the annular groove 22, the pre-cooled cooling plate 19 can cool the chemical raw material on the annular groove 22, while increasing the contact time between the chemical raw material and the cooling air. Then, after the annular groove 22 receives the chemical raw material, it can prevent all the chemical raw material falling into the cooling vessel 17 from accumulating at the bottom of the cooling vessel 17, thus preventing insufficient cooling of the chemical raw material. Moreover, during the rotation of the cooling plate 19, the chemical raw material received on the annular groove 22 can be shaken off. During the shaking process, the chemical raw material can be further contacted with the cooled air, improving the cooling effect of the chemical raw material.
[0053] To improve the contact time between chemical raw materials and cooling air, this invention requires controlling the rotation speed and angle of the cooling plate 19. Therefore, this invention uses a frequency converter to control the rotation frequency of the motor 4 to 5-10 times per minute. A reducer is connected to the output shaft of the motor 4, and the controller 5 and the reducer control the rotation angle of the motor 4 within the range of 0-90 degrees. This allows the cooling plate 19 to rotate 5-10 times per minute within this range. Specifically, the cooling plate 19 can rotate 30 degrees on the first rotation, 60 degrees on the second, and 90 degrees on the third, and then continue rotating 30, 60, and 90 degrees. Controlling the rotation frequency and angle of the motor 4 using a frequency converter, controller 5, and reducer is existing technology and will not be described in detail here. However, this method allows the chemical raw materials received on the annular groove 22 to be shaken into the cooling vessel 17 in batches, thereby increasing the contact time and contact area between the chemical raw materials and the cooling air, and further improving the cooling effect of the chemical raw materials.
[0054] As a preferred embodiment of the present invention: Specifically, in order to ensure that the annular grooves 22 on all the cooling plates 19 in the cooling vessel 17 can receive chemical raw materials, the diameter of the cooling plates 19 in the cooling vessel 17 decreases from top to bottom, so that the annular grooves 22 on each cooling plate 19 can receive chemical raw materials, further avoiding the accumulation of chemical raw materials at the bottom of the cooling vessel 17, which is not conducive to the heat dissipation of chemical raw materials.
[0055] It should be noted that as the diameter of the cooling plate 19 decreases from top to bottom, the lengths of the corresponding belt shaft 7 and rotating shaft 27 of the cooling plate 19 from top to bottom increase accordingly. The specific increase in length can be determined according to the actual volume of the cooling vessel body 17 during the actual production process, and is not specifically limited in this invention.
[0056] As a preferred embodiment of the present invention: Since the cooling plate 19 is made of copper, its instantaneous heat absorption capacity is better than that of aluminum alloy. When chemical raw materials are received on the annular groove 22, the copper cooling plate 19 can absorb the heat of the chemical raw materials in the annular groove 22, which is conducive to heat exchange between the chemical raw materials and the cooling plate 19. Moreover, after the annular groove 22 on the cooling plate 19 absorbs the heat of the chemical raw materials, the heat can be carried away by the cooling air continuously input into the cavity 20, thereby continuously absorbing heat and cooling the chemical raw materials received on the annular groove 22. Of course, the material of the cooling plate 19 can also be other materials with good heat absorption, such as aluminum metal.
[0057] As a preferred embodiment of the present invention: an auger 15 is placed inside the feed pipe 14, one end of the auger 15 extends into the cooling kettle 3, and the other end of the auger 15 is connected to an external motor 4.
[0058] Furthermore, in order to enable the chemical raw materials to smoothly enter the cooling tank 3 through the feed pipe 14, an auger 15 is installed in the feed pipe 14. When the auger 15 is rotated by the external motor 4, it can transport the chemical raw materials in the feed pipe 14, reducing the probability of blockage in the feed pipe 14. At the same time, it can also break up some of the agglomerates in the chemical raw materials. Moreover, one end of the auger 15 extends into the cooling tank 3, where the auger 15 can be used as a stirring component, which is beneficial for the chemical raw materials to disperse in the cooling tank 3 and improve the cooling effect of the chemical raw materials.
[0059] As a preferred embodiment of the present invention: the cooling plate 19 includes a first cooling plate 1901, a second cooling plate 1902 and a third cooling plate 1903, wherein the air outlets 26 on the first cooling plate 1901, the second cooling plate 1902 and the third cooling plate 1903 are all connected to flexible hoses 25, and the length of the flexible hoses 25 is 1-2 cm longer than the distance between adjacent cooling plates.
[0060] Specifically, when the cooling plate 19 is rotating, the vent 26 will come into contact with the chemical raw materials, which may cause the chemical raw materials to enter the vent 26 and block the vent 26. To address this, the present invention connects a flexible hose 25 to the vent 26. The flexible hose 25 is in a swinging state as the cooling plate 19 rotates, which can reduce the amount of chemical raw materials entering the vent 26 and reduce the blockage of the vent 26. In order to further reduce the amount of chemical raw materials entering the vent 26, a filter screen can also be fixed at the end of the flexible hose 25 away from the vent 26.
[0061] Furthermore, since the length of the hose 25 is 1-2 cm longer than the distance between adjacent cooling plates, as the hose 25 rotates with the cooling plate 19, the hose 25 at the bottom of the upper cooling plate can tap the surface of the lower cooling plate and come into contact with the chemical raw materials. For example, in the present invention, the first cooling plate 1901 will tap the surface of the second cooling plate 1902 and come into contact with the chemical raw materials during rotation. During the tapping process, it can reduce the agglomeration of the chemical raw materials. At the same time, the tapping can cause the second cooling plate 1902 to vibrate, reducing the phenomenon of chemical raw materials adhering to the second cooling plate 1902. It should be noted that the number of cooling plates 19 in the present invention is not necessarily three, but is determined according to the volume of the cooling vessel 17.
[0062] As a preferred embodiment of the present invention: a hollow conical disk 23 is provided at the bottom of the cooling vessel body 17, and the bottom of the hollow conical disk 23 is connected to the discharge port 24.
[0063] By setting a hollow conical disk 23 at the bottom of the cooling vessel 17, it is helpful to quickly collect the chemical raw materials after they have cooled. In order to prevent the chemical raw materials accumulated in the hollow conical disk 23 from not cooling sufficiently, stirring blades can also be set in the hollow conical disk 23 and driven by a drive motor. The drive motor is controlled by the controller 5. The drive motor drives the stirring blades to rotate, thereby agitating the chemical raw materials in the hollow conical disk 23, which also helps to cool the chemical raw materials.
[0064] As a preferred embodiment of the present invention: a temperature sensor 18 is provided inside the cooling vessel 17, and the temperature sensor 18 is installed on the inner side wall of the cooling vessel 17.
[0065] During the pre-cooling and cooling of chemical raw materials in the cooling kettle, the temperature sensor 18 can transmit the temperature signal to the controller, so that the staff can know the temperature in the cooling kettle in real time. When the temperature in the cooling kettle reaches the temperature required for cooling of the chemical raw materials, the controller can control the electric valve to open. Of course, in order to know the real-time temperature of the chemical raw materials in the cooling kettle body 17, the number of temperature sensors 18 in the cooling kettle body 17 can be more than one. For example, temperature sensors 18 can be set in the middle of the cooling kettle body 17 or in the conical disk. Their signals are all transmitted to the controller, and then the average value of the temperature information obtained by all temperature sensors 18 is taken to know the average temperature of the chemical raw materials in the cooling kettle.
[0066] Meanwhile, the temperature inside the cooling vessel can be known in real time through the temperature sensor 18, and the chemical cooling equipment can be adjusted according to the actual situation, such as adjusting the pre-cooling time and the output wind speed of the air cooler.
[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
