Description

Technical Field

[0001] The present invention relates to the technical field of chemical production equipment, and particularly relates to an intelligent drying device and method for the production and processing of chlorinated paraffin. Background Art

[0002] Chlorinated paraffin is an organic chloride prepared by introducing chlorine atoms into paraffin hydrocarbon molecules through a chlorination reaction.

[0003] In the production process, enterprises select an advanced process technology that combines thermal chlorination and photocatalysis to produce chlorinated paraffin. Specifically, the synergistic effect of thermal energy and photons is used to decompose chlorine molecules, thereby initiating a substitution reaction. During the production process, enterprises purchase chlorine gas and liquid paraffin externally and introduce the two into a reaction kettle for mixing and reaction. There are a total of 7 reaction kettles in series. After the reaction in the previous reaction kettle is completed, the chlorinated paraffin liquid flows into the subsequent reaction kettle for continued reaction. After the reaction is completed, the chlorinated paraffin liquid flows into a degassing kettle, and at this time, compressed air is introduced to blow away the HCl (hydrogen chloride) gas wrapped therein. After 2 hours of blowing treatment, a stabilizer is added.

[0004] During the production process of chlorinated paraffin, moisture may be absorbed from the air or generated during the reaction, so drying treatment is required. The drying treatment can effectively remove this moisture, thereby ensuring the purity and quality of the product. The specific operation is to send the chlorinated paraffin into a corresponding drying tank, and convey drying gas into the tank body to evaporate and discharge the moisture in the chlorinated paraffin. At the same time, the stirring device needs to be started to continuously stir the chlorinated paraffin during the drying process to ensure uniform heating. However, in actual operation, due to the large volume of the drying tank, there is still a large space in the tank after adding the chlorinated paraffin. This causes the drying gas to need to fill the entire tank body before it can be discharged, thereby prolonging the drying time. In addition, when the stirring device stirs the chlorinated paraffin, due to the relatively empty space in the tank body, some chlorinated paraffin is easily transferred to the relatively empty area in the tank body, resulting in insufficient stirring. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide an intelligent drying device and method for the production and processing of chlorinated paraffin, and the problem to be solved is that the internal volume of the drying tank for drying chlorinated paraffin is large, and there is still a large space after adding the chlorinated paraffin, resulting in the drying gas needing to fill the tank body before it can be discharged, prolonging the drying time.

[0042] Embodiment 1

[0043] An embodiment of the present invention discloses an intelligent drying device and method for the production and processing of chlorinated paraffin.

[0044] Embodiment 1

[0045] Refer to Figures 1-9, which is the first embodiment of the present invention, provides an intelligent drying device and method for the production and processing of chlorinated paraffin. This intelligent drying device for the production and processing of chlorinated paraffin includes a drying tank body 1. An adjusting device for stirring chlorinated paraffin is provided in the drying tank body 1. A drying device for drying chlorinated paraffin is also provided on the drying tank body 1. The adjusting device includes a lifting drive mechanism and a mixing mechanism. The drying device includes an intelligent drying box 2 fixedly installed on the drying tank body 1. A drying pipeline 201 for conveying drying gas is provided on the intelligent drying box 2. The two ends of the drying pipeline 201 are respectively fixedly connected with an air inlet pipe 202 and an exhaust pipe 203. And air filters 204 are provided at the ends of the air inlet pipe 202 and the exhaust pipe 203 located in the drying tank body 1. The lifting drive mechanism includes a lifting cover plate 3 driven by a hydraulic cylinder 4 and in clearance fit with the drying tank body 1. The lifting cover plate 3 slides axially along the drying tank body 1 and is located above the exhaust pipe 203 in the drying tank body 1. Symmetrically distributed positioning rods 301 are fixedly installed at the top end of the lifting cover plate 3. A hinge seat 302 is fixedly installed at the bottom end of the lifting cover plate 3. And a lifting frame 401 is fixedly installed at the end of the positioning rod 301 away from the lifting cover plate 3. The lifting frame 401 is fixedly connected with the piston rod of the hydraulic cylinder 4 and is located above the drying tank body 1. The drying tank body 1 is the core component of the entire device, used to accommodate chlorinated paraffin and carry out drying treatment. Legs for support are provided at the bottom. The intelligent drying box 2 can convey drying gas into the drying tank body 1 through the drying pipeline 201 to realize the drying of chlorinated paraffin. The air inlet pipe 202 and the exhaust pipe 203 are responsible for the drying gas entering and discharging, and the direction is unidirectional, with the gas entering from the bottom and exiting from the top. The air filters 204 are used to block chlorinated paraffin, so that when the drying gas circulates, chlorinated paraffin is not easily introduced into the drying pipeline 201. The lifting cover plate 3 can move up and down through the lifting frame 401 driven by the hydraulic cylinder 4, thereby controlling the actual gas volume in the drying tank body 1, and then shortening the time required for the drying gas to fill the drying tank body 1.

[0046] A feeding hopper 101 and a discharge port 102 communicating with the drying tank body 1 are respectively fixedly installed on the drying tank body 1. And the discharge port 102 is located at the bottom end of the drying tank body 1. A ring of column arrays 103 is fixedly installed at the end of the drying tank body 1 away from the discharge port 102. A hydraulic platform 104 for installing the hydraulic cylinder 4 is fixedly installed at the top end of the column 103. The feeding hopper 101 can add chlorinated paraffin into the drying tank body 1 through a pump body. A control valve is provided at the discharge port 102 for discharging the dried chlorinated paraffin. The column 103 provides stable support for the hydraulic cylinder 4 through the hydraulic platform 104 to ensure the stable operation of the lifting drive mechanism.

[0047] The intelligent drying box 2 is also provided with an intelligent control main body 205. An intake air sensor 206 and an exhaust air sensor 207 corresponding to the intake air pipe 202 and the exhaust air pipe 203 are respectively and fixedly installed on the drying tank body 1. The intake air sensor 206 and the exhaust air sensor 207 are both electrically connected to the intelligent control main body 205. The intake air sensor 206 and the exhaust air sensor 207 are respectively responsible for the real-time monitoring of the intake air pipe 202 and the exhaust air pipe 203. The intelligent control main body 205 can accurately control the flow rate and temperature of the drying gas to ensure the stability and efficiency of the drying process.

[0048] The mixing mechanism includes a driving screw rod 5 fixedly installed on the lifting frame 401. An outer rotating cylinder 6 is movably connected in the drying tank body 1. A threaded cavity 601 in threaded fit with the driving screw rod 5 is formed in the outer rotating cylinder 6. The outer rotating cylinder 6 is rotatably connected in the drying tank body 1 through a bearing 7. One end of the bearing 7 located in the drying tank body 1 is fixedly installed with a rotating shaft 8. A mixing paddle 9 for stirring chlorinated paraffin is fixedly installed at the end of the rotating shaft 8 away from the outer rotating cylinder 6. The driving screw rod 5 can be driven by the lifting frame 401 to move up and down in the outer rotating cylinder 6. When the outer rotating cylinder 6 moves up and down with the driving screw rod 5, due to the threaded cavity 601 and under the limitation of the bearing 7, it rotates in the drying tank body 1. The rotating shaft 8 can rotate synchronously with the outer rotating cylinder 6, and the mixing paddle 9 stirs the chlorinated paraffin to ensure that the chlorinated paraffin is evenly heated during the drying process.

[0049] One end of the driving screw rod 5 extending into the outer rotating cylinder 6 is rotatably installed with a guiding convex block 501. A guiding chute 602 for the limiting sliding of the guiding convex block 501 is formed in the outer rotating cylinder 6 and below the threaded cavity 601. The guiding convex block 501 can cooperate with the guiding chute 602, so that the driving screw rod 5 can move vertically along the axial direction of the outer rotating cylinder 6.

[0050] The mixing mechanism further includes a limiting guide rail 10 fixedly installed in the drying tank body 1 and below the lifting cover plate 3. One end of the rotating shaft 8 passing through the limiting guide rail 10 is fixedly connected to the mixing paddle 9. Sliders 11 are respectively slidably connected to both ends of the limiting guide rail 10. Conical stoppers 12 are fixedly installed on the sliders 11. Symmetrically distributed connecting rods 13 are also provided between the limiting guide rail 10 and the lifting cover plate 3. The bottom end of the connecting rod 13 is hinged to the corresponding slider 11, and the bottom end of the connecting rod 13 is hinged to the lifting cover plate 3 through a hinge seat 302. The limiting guide rail 10 can cooperate with the rotating shaft 8 to further realize the stable support and accurate guiding of the mixing paddle 9. The slider 11 can transmit and convert the lifting movement of the hinge seat 302 connected to the lifting cover plate 3 through the connecting rod 13 into a horizontal linear movement along the limiting guide rail 10. The conical stoppers 12 can move closer to each other through the sliders 11, thereby compressing the space for the mixing paddle 9 to stir and mix, making the stirring more sufficient.

[0051] Arc grooves corresponding to the rotating shaft 8 are provided on the inner sides of the conical blocks 12. A smooth arc surface is provided on the outer sides of the conical blocks 12 and above the mixing paddle 9. The arc grooves of the conical blocks 12 can avoid interfering with the rotation of the rotating shaft 8. The smooth arc surface of the conical blocks 12 makes it difficult for chlorinated paraffin to adhere during the stirring process, enabling the chlorinated paraffin to be fully mixed during the drying process.

[0052] One end of the feeding hopper 101 extending into the drying tank body 1 is located between the conical blocks 12. The design of the feeding hopper 101 can ensure that the chlorinated paraffin does not contact the conical blocks 12 during the feeding process and can be evenly distributed throughout the drying tank body 1.

[0053] When drying chlorinated paraffin during production and processing, the chlorinated paraffin is sent into the drying tank body 1 through the feeding hopper 101 by a pump body. The hydraulic cylinder 4 is driven to lower the lifting cover plate 3, thereby controlling the actual gas volume in the drying tank body 1, and then shortening the time required for the drying gas to fill the drying tank body 1 to prepare for the drying operation. The intelligent drying box 2 conveys the drying gas to the drying tank body 1 through the drying pipeline 201. The gas enters the drying tank body 1 from the bottom through the air inlet pipe 202 and is discharged from the drying tank body 1 after being filtered by the air filter 204 of the exhaust pipe 203. During this process, the mixing device in the adjusting device is used for stirring, and the dried chlorinated paraffin is discharged through the discharge port 102.

[0054] During the drying operation, the drying gas in the drying tank body 1 adopts a one-way flow of entering from the air inlet pipe 202 and exiting from the exhaust pipe 203, with the gas flowing in from the bottom and out from the top. The intelligent control main body 205 monitors the flow rate and temperature of the drying gas in real time through the air inlet sensor 206 and the exhaust sensor 207, and automatically adjusts the drying parameters, thereby realizing the intelligent operation of the device.

[0055] During the process of the hydraulic cylinder 4 driving the lifting cover plate 3 to descend, the transmission screw 5 moves up and down in the outer rotating cylinder 6 driven by the lifting frame 401, and is mutually matched with the guiding convex block 501 and the guiding chute 602 through rotational connection, enabling the transmission screw 5 to move vertically along the axial direction of the outer rotating cylinder 6 and be in threaded cooperation with the threaded cavity 601 in the outer rotating cylinder 6. This causes the outer rotating cylinder 6 to rotate in the drying tank body 1 under the restriction of the bearing 7 and drives the mixing paddle 9 connected to the rotating shaft 8 to rotate synchronously to stir the chlorinated paraffin, ensuring that the chlorinated paraffin is evenly heated during the drying process.

[0056] When the hydraulic cylinder 4 drives the lifting cover plate 3 to reset and rise, the lifting motion of the hinge seat 302 connected to the lifting cover plate 3 is transmitted through the connecting rod 13 and converted into the horizontal linear motion of the slider 11 along the limit guide rail 10, so as to drive the tapered blocks 12 to approach each other, thereby compressing the space for the mixing paddle 9 to stir and mix, making the stirring more sufficient. And the arc grooves of the tapered blocks 12 can avoid interfering with the rotation of the rotating shaft 8 when approaching. The smooth arc surfaces on the tapered blocks 12 make it difficult for chlorinated paraffin to adhere during the stirring process, further enabling the chlorinated paraffin to be fully mixed during the drying process.

[0057] A method for using an intelligent drying device for the production and processing of chlorinated paraffin, comprising the following steps:

[0058] Step 1, when the device needs to be used, first send the chlorinated paraffin into the drying tank body 1 through the feed hopper 101 by means of a pump body to ensure that the chlorinated paraffin is evenly distributed throughout the tank body;

[0059] Step 2, then drive the lifting cover plate 3 to descend through the hydraulic cylinder 4, so as to control the actual gas volume in the drying tank body 1, thereby shortening the time required for the drying gas to fill the drying tank body 1 and preparing for the drying operation;

[0060] Step 3, send the drying gas from the intelligent drying box 2 to the drying tank body 1 through the drying pipeline 201. The gas enters the drying tank body 1 from the bottom through the air inlet pipe 202 and is discharged from the drying tank body 1 after being filtered by the air filter 204 of the exhaust pipe 203;

[0061] Step 4, during this process, the driving screw rod 5 moves up and down in the outer rotating cylinder 6 driven by the lifting frame 401, and through the action of the thread, drives the outer rotating cylinder 6 to rotate under the restriction of the bearing 7, and drives the mixing paddle 9 connected to the rotating shaft 8 to rotate synchronously to stir the chlorinated paraffin;

[0062] Step 5, when the hydraulic cylinder 4 drives the lifting cover plate 3 to reset and rise, drive the slider 11 to move horizontally along the limit guide rail 10 through the connecting rod 13, drive the tapered blocks 12 to approach each other, and compress the stirring space of the mixing paddle 9 to make the stirring more sufficient;

[0063] Step 6, after drying is completed, discharge the dried chlorinated paraffin through the discharge port 102.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention..

A method for using an intelligent drying device for the production and processing of chlorinated paraffin, which is applied to the intelligent drying device for the production and processing of chlorinated paraffin described in claim 8, and is characterized in that: Including the following steps: Step 1, when the device needs to be used, first, chlorinated paraffin is sent into the drying tank body (1) through the feeding hopper (101) by a pump body to ensure that the chlorinated paraffin is evenly distributed throughout the tank body; Step 2, then the hydraulic cylinder (4) is used to drive the lifting cover plate (3) to descend, so as to control the actual gas volume in the drying tank body (1), thereby shortening the time required for the drying gas to fill the drying tank body (1), and preparing for the drying operation; Step 3, the intelligent drying box (2) is used to convey the drying gas to the drying tank body (1) through the drying pipeline (201). The gas enters the drying tank body (1) from the bottom through the air inlet pipe (202) and is discharged from the drying tank body (1) after being filtered by the air filter (204) of the exhaust pipe (203); Step 4, during this process, the driving screw rod (5) moves up and down in the outer rotating cylinder (6) driven by the lifting frame (401), and through the thread action, drives the outer rotating cylinder (6) to rotate under the restriction of the bearing (7), and drives the mixing paddle (9) connected to the rotating shaft (8) to rotate synchronously to stir the chlorinated paraffin; Step 5, when the hydraulic cylinder (4) drives the lifting cover plate (3) to reset and rise, the connecting rod (13) is used to drive the slider (11) to horizontally move along the limiting guide rail (10), driving the conical stoppers (12) to approach each other, compressing the stirring space of the mixing paddle (9) to make the stirring more sufficient; Step 6, after drying is completed, the dried chlorinated paraffin is discharged through the discharge port (102).
