Description

Technical Field

[0001] This utility model relates to the field of paraffin separation technology, and in particular to a separation device for the production of lightweight liquid paraffin. Background Technology

[0002] Light liquid paraffin is usually obtained from petroleum refining and is a common raw material used in industries such as lubricants, cosmetics, and pharmaceuticals. Its production process involves multiple separation steps, the main purpose of which is to separate liquid waxes with low melting points and viscosity from petroleum. In the traditional production of light liquid paraffin, cooling crystallization or solvent dewaxing methods are often used to precipitate high-melting-point paraffins, thereby obtaining light liquid paraffin.

[0003] In existing technologies, such as the "Liquid Paraffin Separation Device" with announcement number CN218077529U, a separation tank is provided, which has an inlet and an outlet, a liquid outlet at the bottom, and a heating component on the outer wall of the tank. A stirring component is also provided inside the tank, and an exhaust pipe is connected to the outlet. While this technology can ensure uniform heating of the material in the separation tank, improving separation effect and efficiency, and the vertical scraper not only acts as a stirrer but also cleans the inner wall of the tank, it shares a common drawback with traditional methods: traditional wax crystal separation technology typically uses a cooling crystallization method, where high-melting-point paraffin is crystallized at low temperatures to separate and remove solid wax crystals. However, this method has the following drawbacks: First, strict temperature control is required. Rapid cooling results in excessively fine wax crystal particles, making effective separation from the liquid wax difficult and affecting the purity of the liquid wax. Conversely, slow cooling leads to excessively large wax crystals, reducing the fluidity of the wax liquid and easily causing blockage of the outlet pipe or slowing down the wax liquid flow rate, thus affecting production efficiency.

[0014] The beneficial effects of this utility model are:

[0015] 1. Through the set crushing component, high melting point paraffin wax is first put into the inside of the separation cylinder. Then, it is slowly cooled to form crystalline wax. At this time, the agitator on the rotating shaft works in conjunction with the crushing cylinder to agitate the wax crystals. During the agitation process, the wax crystals continuously hit the crushing cylinder, which causes large wax crystals to break into multiple small wax crystals. In this way, the liquid wax attached to the wax crystals is fully discharged, thereby improving the purity of the liquid wax. At the same time, it is also convenient for the output of wax crystals in the later stage and avoids blockage. By adopting natural cooling, there is no need for precise temperature control, which reduces the complexity of the production process. Moreover, without relying on temperature control, the production process is less affected by temperature, which improves stability and avoids changes in product quality caused by temperature fluctuations.

[0016] 2. Through the set separation components, after the wax crystals are crushed, the wax crystals and liquid paraffin can be effectively separated. At the same time, the liquid wax can be quickly output. During the output, by rotating the screw, the stop block is moved away from the bottom of the filter plate. At this time, the liquid wax is filtered by the filter plate. It first enters the inside of the diversion box from the inside of the inlet, and then is output from the inside of the outlet to the inside of the conical cylinder. Then it is quickly output from the inside of the outlet pipe, thereby promoting the rapid output of liquid wax. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] Such as this utility model Figures 1 to 6 The diagram shows a separation device for producing lightweight liquid paraffin, including a separation cylinder 1, a conical cylinder 2 fixedly connected to the bottom of the separation cylinder 1, a crushing component for crushing wax crystals inside the separation cylinder 1, the crushing component including a rotating shaft 8 rotatably connected inside the separation cylinder 1, multiple actuating paddles 9 fixedly connected to the outside of the rotating shaft 8, multiple connecting frames 11 fixedly connected in a ring at equal intervals to the outside of the top of the rotating shaft 8, a crushing cylinder 12 fixedly connected to the bottom of the connecting frame 11 away from the rotating shaft 8, the crushing cylinder 12 being located between the rotating shaft 8 and the inner wall of the separation cylinder 1, the conical cylinder 2 containing a separation component for separating wax crystals from liquid wax, the separation component including a filter plate 14 fixedly connected to the bottom of the separation cylinder 1, and a stop block 16 installed at the bottom of the filter plate 14;

[0029] The set crushing component first puts high melting point paraffin wax into the separation cylinder 1 during use. Then, it slowly cools to form crystalline wax. At this time, the agitator 9 on the rotating shaft 8 works with the crushing cylinder 12 to agitate the wax crystals. During the agitation, the wax crystals continuously hit the crushing cylinder 12, which causes large wax crystals to break into multiple small wax crystals. In this way, the liquid wax attached to the wax crystals is fully discharged, thereby improving the purity of the liquid wax. At the same time, it also facilitates the output of wax crystals in the later stage and avoids blockage. By adopting natural cooling, there is no need for precise temperature control, which reduces the complexity of the production process. Moreover, without relying on temperature control, the production process is less affected by temperature, which improves stability and avoids changes in product quality caused by temperature fluctuations.

[0030] like Figures 1 to 6As shown, the crushing cylinder 12 has multiple holes arranged in a ring at equal intervals inside. The top of the filter plate 14 is fixedly connected with multiple arc-shaped plates 15 in a ring at equal intervals. The two sides of the arc-shaped plates 15 are knife-shaped. When the crushing cylinder 12 is inside the separation cylinder 1, the multiple holes inside the crushing cylinder 12 are located on one side of the multiple arc-shaped plates 15. The top of the separation cylinder 1 is fixedly connected with a motor 3. The top of the separation cylinder 1 is connected to a feed pipe 4. The bottom of the feed pipe 4 is connected to the top of the inside of the crushing cylinder 12. The output end of the motor 3 passes through the top of the separation cylinder 1 and is fixedly connected to the top of the rotating shaft 8.

[0031] The arc-shaped plate 15 and the holes inside the crushing cylinder 12 allow high-melting-point paraffin wax to be introduced into the crushing cylinder 12. Since the crushing cylinder 12 is stationary, the holes inside are located on one side of the arc-shaped plate 15. This blocks the holes, preventing a large amount of paraffin wax from entering the outside of the crushing cylinder 12. This ensures that wax crystals are formed only inside the crushing cylinder 12, facilitating subsequent crushing. When the paraffin wax cools and forms crystals, the motor 3 is activated, causing the rotating shaft 8 to rotate with the actuating paddle 9. Simultaneously, the connecting frame 11 rotates the crushing cylinder 12. At this time, the actuating paddle 9 will... The internal disturbance causes large pieces of wax crystals to impact the crushing cylinder 12, thus breaking them into smaller pieces. Simultaneously, the curved plate 15, with its knife-like edges, scrapes away any wax crystals adhering to the inner wall of the crushing cylinder 12 as it rotates, preventing this problem. Furthermore, the internal holes of the crushing cylinder 12 allow the curved plate 15 to further shred the wax crystals, preventing future blockages. It should be noted that in actual use, the separation cylinder 1 can be made of transparent plastic to facilitate observation of the alignment between the curved plate 15 and the internal holes of the crushing cylinder 12.

[0032] like Figures 3 to 6 As shown, multiple first actuating plates 10 are fixedly connected in a ring at equal intervals on the outside of the bottom of the rotating shaft 8. The first actuating plates 10 are arc-shaped, and the length of the first actuating plates 10 is equal to the length of the rotating shaft 8 from one side of the arc plate 15. The bottom of the first actuating plates 10 is in contact with the top of the filter plate 14. Multiple semi-circular holes 31 are opened at the bottom of the crushing cylinder 12.

[0033] With the first actuating plate 10 and the semi-circular hole 31, the rotation speed of the rotating shaft 8 is reduced after the crystal wax is broken. When the broken crystal wax sinks to the top of the filter plate 14, the first actuating plate 10 is actuated to push the crystal wax inside the crushing cylinder 12 out of the semi-circular hole 31, which facilitates the subsequent output of crystal wax. At the same time, by setting the first actuating plate 10 to be arc-shaped, the first actuating plate 10 can push the crystal wax from the inside to the outside, avoiding the problem of residue.

[0034] like Figures 3 to 6 As shown, multiple second actuating plates 13 are fixedly connected in a ring at equal intervals on the outside of the bottom of the crushing cylinder 12. The second actuating plates 13 are arc-shaped, and the length of the second actuating plates 13 is equal to the length of the distance between the outer wall of the crushing cylinder 12 and the inner wall of the separation cylinder 1. The bottom of the second actuating plates 13 is in contact with the top of the filter plate 14.

[0035] With the second actuating plate 13 in place, some crystal wax will be impacted between the inner wall of the crushing cylinder 12 and the separating cylinder 1 due to the holes inside the crushing cylinder 12. When the rotating shaft 8 rotates, the crushing cylinder 12 will rotate with the second actuating plate 13. The second actuating plate 13 is designed to be arc-shaped, which will push the crystal wax to the inner wall of the separating cylinder 1, thus facilitating the subsequent output.

[0036] like Figure 3 and Figure 6 As shown, multiple fine brushes are fixedly connected to the bottom of the second actuating plate 13 and the first actuating plate 10. A crystal outlet tube 17 is connected to one side of the separation cylinder 1. A plug 18 is threaded inside the crystal outlet tube 17. A pull rod 19 is fixedly connected to one side of the plug 18. Multiple holes are opened inside the filter plate 14. The size of the holes inside the filter plate 14 is smaller than the size of the holes inside the crushing cylinder 12.

[0037] Through the crystal outlet tube 17 and the holes in the filter plate 14, the liquid wax is released between the output crystal waxes. Since the holes in the filter plate 14 are smaller than the holes inside the crushing cylinder 12, the liquid wax passes through the inside of the filter plate 14, causing the liquid wax to remain on the top of the filter plate 14. When the liquid wax is completely output, the first actuating plate 10 and the second actuating plate 13 will push the liquid wax to the inner wall of the separation cylinder 1. At this time, the pull rod 19, using the thread action, pushes the plug 18 away from the inside of the crystal outlet tube 17, thereby causing the liquid wax to be output from the inside of the crystal outlet tube 17, which facilitates the collection of liquid wax. At the same time, the fine brushes at the bottom of the second actuating plate 13 and the first actuating plate 10 prevent the liquid wax from clogging the holes.

[0038] like Figures 1 to 3As shown, a diversion box 7 is fixedly connected to both sides of the separating cylinder 1. The top and bottom of the diversion box 7 near the separating cylinder 1 are respectively provided with an inlet 20 and an outlet 21. When the top of the stop block 16 contacts the bottom of the filter plate 14, the position of the stop block 16 corresponds to the position of the inlet 20. The bottom of the conical cylinder 2 is connected to an outlet pipe 5. A fixing column 22 is fixedly connected to the bottom of the conical cylinder 2. A screw 24 is threaded inside the fixing column 22. A protective cylinder 23 is rotatably engaged at the top of the screw 24. The top of the protective cylinder 23 is fixedly connected to the bottom of the stop block 16, and the bottom of the protective cylinder 23 is slidably engaged with the inside of the top of the fixing column 22.

[0039] By using the separation components, after the wax crystals are crushed, the wax crystals and liquid paraffin can be effectively separated, while also promoting the rapid output of liquid wax. During output, by rotating the screw 24, the screw thread causes the protective cylinder 23 to move away from the bottom of the filter plate 14, carrying the stop block 16. When the stop block 16 moves to one side of the distribution box 7, between the inlet 20 and the outlet 21, the liquid wax is filtered by the filter plate 14. It first enters the distribution box 7 from the inside of the inlet 20, and then exits from the inside of the outlet 21 into the conical cylinder 2, and then is rapidly output from the inside of the outlet pipe 5. This promotes the rapid output of liquid wax. At the same time, the protective cylinder 23 prevents the liquid wax from corroding the screw 24, thus allowing the screw 24 to be used for a long time.

[0040] like Figures 1 to 3 As shown, a fixed frame 6 is fixedly connected to the outside of the separating cylinder 1. A bracket 27 is fixedly connected to one side of the fixed frame 6. A drive wheel 26 is rotatably connected to the end of the bracket 27 away from the fixed frame 6 via a shaft. A fixed plate 28 is fixedly connected to the top of one end of the bracket 27. A driven wheel 25 is fixedly connected to the bottom of the screw 24. One side of the driven wheel 25 is connected to the outside of the drive wheel 26 via a belt. A rotating wheel 29 is fixedly connected to the top of the drive wheel 26 through the inside of the fixed plate 28 via a shaft. An insert rod 30 is slidably connected inside the rotating wheel 29. A positioning hole is opened on the top of the fixed plate 28. The bottom end of the insert rod 30 passes through the inside of the rotating wheel 29 and connects to the positioning hole on the top of the fixed plate 28.

[0041] The drive wheel 26 and the insert rod 30 facilitate the rotation and positioning of the screw 24. When outputting liquid wax, the insert rod 30 is first pulled out of the positioning hole of the fixed plate 28. Then, the rotating wheel 29 is rotated, which causes the drive wheel 26 to rotate with the driven wheel 25, thereby causing the screw 24 to rotate, thus facilitating the rapid output of liquid wax.
