Description

Technical Field

[0001] The utility model relates to the technical field of industrial equipment, in particular to a non-jacketed bottom-heating extraction tank. Background Art

[0002] The extraction tank is a kind of leaching extraction equipment often used in the pharmaceutical industry. By putting the material and solvent into the inside of the container, the temperature, pressure and other conditions are changed to allow the solvent to enter the material. Then, by stirring, the solvent extracts the active ingredients in the material to the outside, thereby obtaining the corresponding extract solvent, and then performing solid-liquid separation.

[0003] Most of the current extraction tanks are jacketed. By setting an interlayer on the inner wall of the tank, a steam pipe is spirally set in the interlayer for heating, and the heating effect is good. However, in actual use, when the total amount of solid and liquid materials is small, the steam in the upper part of the tank is in an empty flow state, resulting in heat energy waste. At the same time, when the steam pipe is damaged, it is inconvenient to repair. Usually, it is necessary to use cutting equipment to cut the outer interlayer of the tank, and then weld it after the repair is completed. This is not only troublesome, but also affects the strength during subsequent use. In addition, during use, it is also very troublesome to discharge and collect the slag. For this reason, a non-jacketed bottom heating extraction tank is specially provided to solve the above problems. Utility Model Content

[0026] The embodiment of the present application provides a non-jacketed bottom-heating extraction tank, which solves the problem that when the total amount of solid and liquid materials in the existing jacketed extraction tank is small, the steam in the upper part of the tank body wastes heat energy, and when the steam pipe is damaged, it is inconvenient to repair and it is very troublesome to discharge and collect the slag.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The embodiment of the utility model discloses a jacket-free bottom-heating extraction tank.

[0029] According to the attached Figure 1-3 As shown, it includes an extraction tank body 1, which includes a non-interlayer explosion-proof tank 11. A stirring rod 13 is rotatably provided inside the non-interlayer explosion-proof tank 11. A feed port 12 is provided at the top of the non-interlayer explosion-proof tank 11. A support 15 is fixedly provided on the top of the non-interlayer explosion-proof tank 11. A drive motor 14 is fixedly installed on the top of the support 15. The output end of the drive motor 14 is fixedly installed with the stirring rod 13. A support frame 16 is fixedly installed on the outer surface of the bottom end of the non-interlayer explosion-proof tank 11, and a lifting drive cylinder 27 is fixedly installed inside the support frame 16.

[0030] During use, the material is fed into the non-interlayer explosion-proof tank 11 through the feed port 12, and the driving motor 14 is started to drive the stirring rod 13 to rotate, so that the solvent and the material are fully mixed to extract the extract.

[0031] An integrated bottom cover 2 is installed at the bottom of the extraction tank body 1. The integrated bottom cover 2 includes a cover body 21, a drain pipe 22, a steam coil 24, a slag filter basket 25 and a lifting drive cylinder 27.

[0032] The cover body 21 is movably inserted into the bottom of the extraction tank body 1, and the lifting drive cylinder 27 is installed on both sides of the bottom of the extraction tank body 1. The cover body 21 is rotatably connected to the output end of the lifting drive cylinder 27, and the output end of the lifting drive cylinder 27 is fixedly installed with a connecting seat 28. The two sides of the bottom end of the cover body 21 are fixedly welded with a rotating shaft 29, and the end of the rotating shaft 29 is rotatably connected to the connecting seat 28.

[0033] The cover 21 is driven up and down by the lifting drive cylinder 27 so that the cover 21 can be inserted and pulled out from the bottom of the non-interlayer explosion-proof tank 11. After being pulled out, the cover 21 is rotated about the rotating shaft 29 so that the cover 21 is turned to one side, which facilitates the cleaning of the slag on the top of the cover 21.

[0034] The drain pipe 22 is fixedly arranged at the bottom of the cover body 21. The internal thread of the drain pipe 22 is connected to a seal 23. The top of the seal 23 is movably inserted into the inner bottom of the cover body 21. The seal 23 includes a set of threaded rods and sealing plugs installed at the ends of the threaded rods. By rotating the threaded rods, the sealing plugs are pulled downward from the bottom of the cover body 21. At this time, the leachate is discharged outward from the drain pipe 22. The threaded rods are rotated in the opposite direction so that the sealing plug is inserted into the bottom of the cover body 21 for sealing.

[0035] The steam coil 24 is arranged inside the cover body 21, and steam circulation pipes 210 are installed on both sides of the cover body 21. The two ends of the steam coil 24 are respectively connected to two groups of steam circulation pipes 210. The upper part of the steam circulation pipe 210 is an ascending spiral, and the lower part of the steam circulation pipe 210 is a horizontal spiral, thereby increasing the contact area between the steam coil 24 and the internal solvent and improving the heating speed. At the same time, when the steam coil 24 is damaged, the cover body 21 can be directly removed for maintenance, and the maintenance difficulty is low.

[0036] The slag filter basket 25 is movably inserted into the top of the cover body 21. A support ring 26 is fixedly welded inside the cover body 21. The outer edge of the top of the slag filter basket 25 is against the top of the support ring 26. The slag filter basket 25 is used to receive solid waste slag, which is convenient for centralized slag discharge.
