Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of high mint processing, and more specifically to a crystallization equipment for improving menthol out-of-brain rate. BACKGROUND

[0002] Menthol, also known as menthol, is a terpenoid organic compound with the chemical formula C10H20O. Menthol is extracted from the leaves and stems of mint, white crystals, and is the main component of mint and peppermint essential oil. There are generally two isomers of menthol (D and L types), and natural menthol is mainly the left-handed isomer (L-menthol). Here, menthol generally refers to racemic menthol (DL-menthol). Menthol can be used as a fragrance in toothpaste, perfume, beverage and candy. It is used as a stimulant in medicine, acting on the skin or mucous membrane, and has a cooling and itching effect.

[0003] The patent file with patent number CN204319822U discloses a menthol crystallization device, which comprises a crystallization chamber, a temperature compensation device, a temperature sensor and a controller. The inner side of the wall of the crystallization chamber is provided with a heat preservation layer. A box body is fixed at the bottom of the crystallization chamber. A ventilation opening is formed at the top of the crystallization chamber. An air exchange fan is installed at the ventilation opening. A reverse tapered crystallization barrel is arranged above the box body in the crystallization chamber. A discharge port and a discharge valve are arranged at the lower end of the reverse tapered crystallization barrel. A pipeline is further arranged in the box body. Refrigerant is arranged in the pipeline and the box body. The temperature compensation device is vertically distributed on the four walls of the crystallization chamber in a ring shape. The temperature distribution of the temperature sensor in the crystallization chamber is a detection signal. The signal is processed by a computer to control the temperature compensation device. The heat preservation and temperature compensation effect is good. The discharge is convenient. The structure is simple. The work is stable and reliable.

[0004] The traditional menthol crystallization device has certain disadvantages in use. In use, the traditional menthol crystallization device puts the mint crude oil into an iron bucket and buries it in ice blocks to reduce the temperature to below 0℃. The menthol is separated from the mint crude oil as a crystalline body, and then the oil is filtered out. The operation steps are complicated, and manual separation of the mint oil is required, which reduces the efficiency of the menthol crystallization and separation operation. Secondly, the single filter screen structure design of the traditional menthol crystallization device makes it easy for small particles of menthol to be discharged together, thereby reducing the menthol out-of-brain rate of the menthol crystallization device. At the same time, the traditional menthol crystallization device does not have an auxiliary cooling structure. When the menthol crystallization device is used, the user needs to constantly add ice blocks for cooling operation. The function is single, and the melting of the ice blocks will affect the menthol crystallization efficiency. SUMMARY

[0021] The present application has the following advantages:

[0022] 1. By setting the sliding clamping seat and the lifting frame, the crystallization equipment for improving menthol yield can complete the separation and discharge operation of multiple groups of menthol at one time, improving the discharge efficiency of menthol. When operating, the user opens the sealed upper cover, pours the menthol oil into the inner sleeve box, pours the ice into the cooling box, makes the ice bury the inner sleeve box, and makes the temperature in the inner sleeve box drop below 0℃. The menthol is separated from the menthol crude oil as a crystalline body. The user starts the hydraulic rod, and the hydraulic rod drives the lifting frame to move up through the two ends of the lifting frame. When the lifting frame moves up, the lifting frame pulls several groups of inner sleeve boxes up at the same time by using the butt joint clamping rod. Secondly, the butt joint of the butt joint clamp and the strip-shaped clamping groove makes the outer sleeve box and the cooling box in a relative fixed state. When the lifting frame pulls several groups of inner sleeve boxes up at the same time, it is convenient to separate the inner sleeve box and the outer sleeve box. The lower end of the inner sleeve box is provided with a filter. After the inner sleeve box is separated, the two groups of filter screen structures in the filter can separate the menthol oil and the menthol. The user can discharge the menthol oil in the outer sleeve box by opening the valve on the liquid discharge pipe. When the inner sleeve box is separated and moved up, the two groups of gears are driven to rotate by the motor and the chain structure at the same time. The rotation of the gears can drive the sliding clamping seat by the driving rack, so that the sliding clamping seat drives several groups of inner sleeve boxes to translate through the lifting frame, so as to move several groups of inner sleeve boxes out, separate the inner sleeve box and the cooling box, and finally take down the inner sleeve box by using the splicing clamping groove of the butt joint clamping rod. The menthol taking operation is more convenient. The setting of the sliding clamping seat and the lifting frame makes the crystallization equipment have an automatic separation structure, and improves the use effect.

[0023] 2、By setting the filter, in the use of the crystallization equipment for improving menthol yield, the double filtering structure of the filter can be used for double filtering operation according to the thickness of menthol, so as to avoid the discharge of small particle menthol, improve the menthol yield of the crystallization equipment, and the double filtering operation of menthol can be realized by using the filter screen and the arc filter screen. The filter screen and the arc filter screen have different filter hole sizes, the filter hole of the filter screen is larger than that of the arc filter screen, so that the filter screen and the arc filter screen constitute a double filtering structure, which can avoid the outflow of small particle menthol without reducing the filtering speed. When the arc filter screen and the filter screen are disassembled and cleaned, the filter screen can be taken out first, and then the arc filter screen is taken out, and the residual menthol is cleaned. At the same time, the arc structure of the arc filter screen can prolong the filtering time of the arc filter screen, avoid the blockage of the arc filter screen in a short time, and make the small particle menthol accumulate in the middle of the arc filter screen. By setting the filter, the use of the filter screen and the arc filter screen can effectively reduce the loss of small particle menthol and improve the yield.

[0024] 3、By setting the refrigeration pipe, in the use of the crystallization equipment for improving menthol yield, the refrigeration pipe is provided to have an active refrigeration structure in the cooling box. When operating, the user can guide the refrigerant into the refrigeration pipe by using the compressor to cool the ice block in the cooling box, so that the ice block can maintain a low temperature for a long time. In addition, the user can open the drain pipe to discharge the melted ice block in the cooling box. In addition, the upper end of the sliding holder is provided with a cylindrical mounting groove, which can be used to install the hydraulic rod. When the sliding holder moves on the driving rack, the abutment between the limiting clamping strip and the limiting sliding groove can avoid the falling of the sliding holder, and improve the safety of the sliding holder and the lifting frame during operation.

The number of inner boxes 8 and outer boxes 9 is several sets, with the outer box 9 fixedly installed inside the cooling box 1. The inner box 8 is movably fitted inside the outer box 9. A filter element 16 for separating menthol is fixedly installed on the lower outer surface of the inner box 8. A lifting frame 7 for driving the inner box 8 to move up and down is movably installed on the upper end of the cooling box 1. Hydraulic rods 6 are installed at the lower part of the outer surfaces of both ends of the lifting frame 7, and sliding seats 5 are fitted onto the outer surfaces of the hydraulic rods 6. The sliding seats 5 are movably connected to the outer surfaces of both ends of the cooling box 1. A drain pipe 2 for discharging menthol oil is provided on the outer surface of one end of the outer box 9.

[0035] The inner casing 8 and the lifting frame 7 are fixed together by a docking rod 10. The upper middle part of the inner casing 8 is provided with a docking seat 14 for use with the docking rod 10. A sealing cover 15 is installed on the upper side of the inner casing 8 near the docking seat 14. When the user lifts the inner casing 8 with the hydraulic rod 6 through the lifting frame 7, the inner casing 8 can be quickly separated by the use of the docking rod 10 and the docking seat 14, making it convenient for the user to take out the menthol inside the inner casing 8.

[0036] The outer surface of the outer sleeve box 9 is provided with a strip-shaped clamping groove 13 at the lower part of both sides, and the inner side of the cooling box 1 is fixedly provided with a butt joint clamp 25 matched with the strip-shaped clamping groove 13. The butt joint clamp 25 and the strip-shaped clamping groove 13 are spliced and fixed, and the relative fixed state between the outer sleeve box 9 and the cooling box 1 is achieved by the butt joint of the butt joint clamp 25 and the strip-shaped clamping groove 13. When the hoisting frame 7 pulls the inner sleeve boxes 8 upwards, the inner sleeve boxes 8 and the outer sleeve box 9 are separated.

[0037] The filter 16 comprises an arc-shaped filter screen 17, a splicing frame 18 and a filter screen 19. The filter screen 19 is spliced and installed at the inner side of the upper end of the splicing frame 18, and the arc-shaped filter screen 17 is spliced and installed at the inner side of the lower end of the splicing frame 18. When the inner sleeve box 8 moves upwards, the filter screen 19 and the arc-shaped filter screen 17 can perform double filtering operation on menthol. The filter holes of the filter screen 19 and the arc-shaped filter screen 17 are different in size, and the filter holes of the filter screen 19 are larger than those of the arc-shaped filter screen 17, so that the filter screen 19 and the arc-shaped filter screen 17 form a double filtering structure, which can prevent small particles of menthol from flowing out without reducing the filtering speed.

[0038] The outer surface of the arc-shaped filter screen 17 is in an arc-shaped structure. The arc-shaped filter screen 17, the filter screen 19 and the splicing frame 18 are fixed by butt joint with a splicing clamping frame 30. The splicing clamping frame 30 is installed in a clamping groove type structure. When the arc-shaped filter screen 17 and the filter screen 19 are disassembled and cleaned, the filter screen 19 can be taken out first from top to bottom, and then the arc-shaped filter screen 17 is taken out. The residual menthol on the arc-shaped filter screen 17 is cleaned. Meanwhile, the arc-shaped structure of the arc-shaped filter screen 17 can prolong the filtering time of the arc-shaped filter screen 17, avoid the arc-shaped filter screen 17 from being blocked in a short time, and make small particles of menthol accumulate in the middle part of the arc-shaped filter screen 17.

[0039] The outer surface of the cooling box 1 is fixedly provided with two drive racks 4 matched with the sliding clamping seat 5 at both ends. The sliding clamping seat 5 and the drive rack 4 are driven by a gear 22. When the inner sleeve box 8 is separated by moving upwards, the rotation of the gear 22 can drive the sliding clamping seat 5 together with the drive rack 4, so that the sliding clamping seat 5 drives the inner sleeve box 8 to move through the hoisting frame 7, thereby moving the inner sleeve box 8 out of the cooling box 1, and facilitating the user to take out the inner sleeve box 8.

[0040] The side edge of the sliding clamping seat 5 is provided with two sliding grooves 23 matched with the drive rack 4. The inner side of the sliding groove 23 is fixedly provided with two limiting clamping strips 24. The upper and lower ends of the drive rack 4 are provided with limiting sliding grooves 21 matched with the limiting clamping strips 24. The upper middle part of the sliding clamping seat 5 is provided with a cylindrical mounting groove 20. When the sliding clamping seat 5 moves on the drive rack 4, the butt joint between the limiting clamping strips 24 and the limiting sliding grooves 21 can avoid the sliding clamping seat 5 from falling off.

[0041] The inner side of the cooling box 1 is fixedly provided with a refrigeration pipe 26, and the middle of the rear end of the cooling box 1 is fixedly provided with a compressor 27. The user can guide the refrigerant into the refrigeration pipe 26 by using the compressor 27, so as to cool the ice blocks in the cooling box 1.

[0042] The outer surface of one end of the docking rod 10 is provided with a splicing slot 28 matched with the docking seat 14, and the outer surface of the other end of the docking rod 10 is provided with a docking ring 29 matched with the lifting frame 7.

[0043] The upper part of the front end of the cooling box 1 is fixedly provided with a water inlet pipe 11, and the lower part of the front end of the cooling box 1 is fixedly provided with a drain pipe 3. The lower end of the cooling box 1 is fixedly provided with a plurality of support frames 12.

[0044] The crystallization equipment for improving the menthol outflow rate can complete the separation and discharge operation of a plurality of groups of menthol at one time, thereby improving the discharge efficiency of menthol. When in operation, the user opens the sealing upper cover 15, pours the menthol oil into the inner sleeve box 8, and pours the ice blocks into the cooling box 1, so that the ice blocks bury the inner sleeve box 8, and the temperature in the inner sleeve box 8 is reduced to below 0℃. The menthol crystals are separated from the menthol crude oil. The user starts the hydraulic rod 6, so that the hydraulic rod 6 drives the lifting frame 7 to move upward through the two ends of the lifting frame 7. When the lifting frame 7 moves upward, the lifting frame 7 pulls a plurality of groups of inner sleeve boxes 8 upward through the docking rod 10. The docking of the docking clamp 25 and the strip-shaped slot 13 makes the outer sleeve box 9 and the cooling box 1 in a relative fixed state. When the lifting frame 7 pulls a plurality of groups of inner sleeve boxes 8 upward, the inner sleeve box 8 and the outer sleeve box 9 are separated. The lower end of the inner sleeve box 8 is provided with a filter 16. After the inner sleeve box 8 is separated, the two groups of filter screen structures in the filter 16 can separate the menthol oil and the menthol. The user opens the valve on the drain pipe 2 to discharge the menthol oil in the outer sleeve box 9. When the inner sleeve box 8 is separated, the two groups of gears 22 are driven to rotate through the motor and chain structure. The rotation of the gears 22 drives the sliding seat 5 through the driving rack 4, so that the sliding seat 5 drives a plurality of groups of inner sleeve boxes 8 to move through the lifting frame 7, thereby moving the plurality of groups of inner sleeve boxes 8, separating the inner sleeve box 8 and the cooling box 1, and finally taking down the inner sleeve box 8 through the splicing slot 28 of the docking rod 10, so that the menthol is more convenient to take. The sliding seat 5 and the lifting frame 7 make the crystallization equipment have an automatic separation structure, thereby improving the use effect.

[0045] By setting the filter 16, in the use of the crystallization equipment for improving menthol outflow rate, the double filtering structure of the filter 16 can be used to double filter the menthol according to its thickness, so as to avoid the small particle menthol from flowing out and improve the menthol outflow rate of the crystallization equipment. In operation, the filter screen 19 and the arc-shaped filter screen 17 can be used to double filter the menthol. The filter holes of the filter screen 19 and the arc-shaped filter screen 17 are different in size, and the filter holes of the filter screen 19 are larger than those of the arc-shaped filter screen 17, so that the filter screen 19 and the arc-shaped filter screen 17 form a double filtering structure. In this way, the small particle menthol can be prevented from flowing out without reducing the filtering speed. When the arc-shaped filter screen 17 and the filter screen 19 are disassembled and cleaned, the filter screen 19 can be taken out first from top to bottom, and then the arc-shaped filter screen 17 is taken out. The residual menthol on the arc-shaped filter screen 17 can be cleaned. Meanwhile, the arc-shaped structure of the arc-shaped filter screen 17 can prolong the filtering time of the arc-shaped filter screen 17 and prevent the arc-shaped filter screen 17 from being blocked in a short time, so that the small particle menthol is accumulated in the middle of the arc-shaped filter screen 17. By setting the filter 16 and using the filter screen 19 and the arc-shaped filter screen 17, the loss of small particle menthol can be effectively reduced, and the menthol outflow rate can be improved.

[0046] By setting the refrigeration pipe 26, in the use of the crystallization equipment for improving menthol outflow rate, the refrigeration pipe 26 is set to have an active refrigeration structure in the cooling box 1. In operation, the user can use the compressor 27 to guide the refrigerant into the refrigeration pipe 26 to cool the ice in the cooling box 1, so that the ice can maintain a low temperature for a long time. Then, the user can open the drain pipe 3 to discharge the melted ice in the cooling box 1. The upper end of the sliding bracket 5 is provided with a cylindrical mounting groove 20, which can be used to install the hydraulic rod 6. When the sliding bracket 5 moves on the driving rack 4, the abutment between the limiting clamping strip 24 and the limiting sliding groove 21 can prevent the sliding bracket 5 from falling off, thereby improving the safety of the sliding bracket 5 and the lifting frame 7 in operation.
