[0036] A sealing structure 80 for sealing the discharge port 30, comprising: a ring plate 800, the end of which is provided with a T-shaped groove 8000 in the circumferential direction; a threaded sealing joint arranged at the top of the ring plate 800 and threadedly connected with the discharge port 30, the threaded sealing joint comprising an upper threaded sleeve 802 and a sealing ring 808 arranged between the upper threaded sleeve 802 and a sealing sleeve 804; the sealing sleeve 804 is provided with a convex cover 8042 at the end thereof for sealing the discharge port 30, is fixed to the inner wall of the threaded sealing joint, and the inner wall thereof is provided with an adaptive groove 8040 in the circumferential direction; a sealing circular plate 806 is slidably connected with the T-shaped groove 8000 through a clamping rod 8060 arranged at the outer periphery thereof; a fixed rod 8062 is connected with the sealing circular plate 806 at one end and is provided with a leakage prevention structure at the other end, the leakage prevention structure comprising a spring 8064 sleeved on the fixed rod 8062, a plug 8066 arranged at the end of the fixed rod 8062, a clamping block 8068 arranged on the outer wall of the plug 8066 in the circumferential direction, and a sealing ring 8070 arranged at the end of the plug 8066 and abutting against the inner wall of the sealing sleeve 804, and the top of the sealing circular plate 806 is provided with a handle 8072 for rotating the sealing circular plate 806; when the sealing circular plate 806 is rotated, the leakage prevention structure is embedded in the adaptive groove 8040 to form a radial seal, and the clamping rod 8060 is axially locked along the T-shaped groove 8000 to realize bidirectional sealing of the discharge port 30.

[0037] Specifically, the case realizes reliable sealing through the dual effects of mechanical linkage and elastic compression, and the specific process is as follows:

[0038] S1, initial state

[0039] The sealing circular plate 806 is in an open position, the clamping rod 8060 is located at the entrance end of the T-shaped groove 8000, and the plug 8066 of the leakage prevention structure is separated from the inner wall of the sealing sleeve 804;

[0040] S2, rotation locking

[0041] The sealing circular plate 806 is rotated through the handle 8072 to drive the clamping rod 8060 to slide along the T-shaped groove 8000 until the clamping rod enters the horizontal segment axial locking position of the T-shaped groove;

[0042] S3, radial sealing

[0043] The end of the fixed rod 8062 is pushed into the matching groove 8040 of the sealing sleeve 804 by the rotating motion, and the spring 8064 is compressed to generate elastic force, which pushes the sealing ring 8070 to tightly adhere to the inner wall of the sealing sleeve 804;

[0044] S4, bidirectional sealing is formed

[0045] Axial sealing: the clamping rod 8060 is limited by the horizontal section of the T-shaped groove, preventing the sealing disc 806 from retreating;

[0046] Radial sealing: the elastic force of the spring 8064 makes the sealing ring 8070 tightly adhere to the matching groove 8040, thereby blocking the liquid leakage path.

[0047] It should be noted that when the internal pressure of the barrel 10 increases, the liquid pressure acts on the end surface of the plug 8066, further compressing the spring 8064, so that the contact pressure between the sealing ring 8070 and the sealing sleeve 804 increases, realizing self-tightening sealing.

[0048] Specifically, the axial locking force is converted by rotating motion, avoiding the problem of traditional threaded sealing that requires multiple turns to tighten, and the sealing speed is improved by more than 50%. At the same time, the spring 8064 provides initial pre-tightening force, and fluid pressure assists to enhance sealing, solving the problem that traditional sealing is prone to leakage at low pressure and failure at high pressure. In addition, the sealing ring 8070 and the plug 8066 can be quickly disassembled and replaced, and compared with the overall plug of the comparative file, the maintenance cost is reduced by 60%.

[0049] The inside of the barrel 10 is also provided with a material collecting port 90 extending to the top, one end of the material collecting port 90 is connected with a filter element 110; the filter element 110 includes a first filter membrane 1110, a second filter membrane 1102 and a third filter membrane 1104 which are sequentially stacked.

[0050] Working principle:

[0051] Firstly, inject the mixed liquid of mulberry leaves into the barrel 10 through the feeding port 50, and drive the driving gear 202 to engage and drive the transmission gear 102 by the driving device 200, so that the barrel interior is stirred; the mixed liquid flows through the filter 110 connected with the collecting port 90 under the action of centrifugal force, wherein the first filter membrane 1110, the second filter membrane 1102 and the third filter membrane 1104 intercept impurities and separate effective components in stages, and the filtrate is collected into the collecting port 90; after the extraction is completed, the filtering efficiency is enhanced by pressurizing through the pressurizing port 60, finally the handle 8072 on the rotary sealing circular plate 806 is rotated, the clamping rod 8060 is axially locked along the T-shaped groove 8000, meanwhile the plug 8066 of the leakage prevention structure is radially embedded into the adaptive groove 8040 under the action of the spring 8064, and the bidirectional sealing of the discharging port 30 is realized by cooperating with the sealing ring 8070, so that the leakage is prevented; the residue can be discharged from the discharging port 30 after the sealing is released, and the whole extraction process is completed.

[0052] The preferred embodiments of the utility model are described above only, and are not used for limiting the utility model, for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
