[0035] The following is an explanation of the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0036] See also Figures 1 to 5 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the restrictive conditions for the implementation of the utility model, so they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model.

[0037] See also Figures 1 to 5 The utility model discloses a slag discharge door structure of an extraction tank and an extraction tank using the same, which can be used to improve the problem that the door body 220 at the slag discharge port of the existing extraction tank is complicated in the opening and closing process and is not easy to discharge slag quickly during use. Specifically, the slag discharge door structure of the extraction tank may include a positioning flange 100, a cover flange 200 and a rotating flange 300. Among them, the positioning flange 100 is connected to the tank body 10 of the extraction tank and is located at the end of the slag discharge cylinder of the extraction tank. The cover flange 200 is connected to the door body 220 for blocking the slag discharge door, and the cover flange 200 and the positioning flange 100 can be allowed to fit. When the cover flange 200 fits with the positioning flange 100, the rotating flange 300 is connected between the positioning flange 100 and the cover flange 200 to ensure that the cover flange 200 and the positioning flange 100 are tightly connected.

[0038] See also Figures 1 to 5In one embodiment, the positioning flange 100 includes a positioning portion 110 and a connecting portion 120, wherein the connecting portion 120 is fixedly connected to the tank body 10 of the extraction tank, and the positioning portion 110 is used to connect to the cover flange 200. The connecting portion 120 and the tank body 10 of the extraction tank can be connected by welding to improve the connection strength between the connecting portion 120 and the extraction tank. The positioning portion 110 can be an annular structure, or the positioning portion 110 can also be a plurality of gear teeth structures, i.e., fourth gear teeth, and the fourth gear teeth are evenly arranged on the periphery of the connecting portion 120.

[0039] A plurality of first gear teeth 210 are evenly arranged on the periphery of the cover flange 200, and the upper side surface of the first gear teeth 210 can be allowed to fit on the positioning portion 110. The rotating flange 300 is rotatably connected to the extraction tank, and a lower clamping portion 310 is arranged on the rotating flange 300. A plurality of second gear teeth 311 are evenly arranged on the lower clamping portion 310, and the number of the first gear teeth 210 and the second gear teeth 311 is set in equal proportion. It should be noted that the gap between the teeth of adjacent second gear teeth 311 is greater than the tooth width of the first gear teeth 210. Therefore, in the actual connection process, the rotating flange 300 is located at the first position, and the second gear teeth 311 on the cover flange 200 can be allowed to pass through the gap between the adjacent second gear teeth 311 on the rotating flange 300 and connect with the positioning flange 100. Then, the rotating flange 300 is driven to rotate, so that the rotating flange 300 is located at the second position, and the cover flange 200 is clamped between the lower clamping portion 310 and the positioning portion 110. By rotating the flange 300 , the cover flange 200 and the positioning flange 100 can be tightly connected.

[0040] Specifically, when the rotating flange 300 rotates to a position where the projection of the second gear teeth 311 and the first gear teeth 210 overlap, the clamping portion 310 limits the cover flange 200, and the rotating flange 300 realizes a fixed connection between the cover flange 200 and the positioning flange 100; when the rotating flange 300 rotates to a position where the projection of the second gear teeth 311 and the first gear teeth 210 are offset, the cover flange 200 can be disengaged from the rotating flange 300, that is, disengaged from the limit of the lower clamping portion 310, and the rotating flange 300 releases the fixed connection between the cover flange 200 and the positioning flange 100.

[0041] Furthermore, in order to improve the sealing effect between the cover flange 200 and the positioning flange 100 during the connection process, a sealing ring 400 may be provided between the positioning flange 100 and the cover flange 200. By providing the sealing ring 400 between the cover flange 200 and the positioning flange 100, the sealing effect of the device during actual use can be improved.

[0042] See also Figures 1 to 5In one embodiment, in order to ensure the rotation position of the rotating flange 300 during the rotation process, a plurality of guide pads 121 may be fixedly connected to the positioning flange 100 , and the guide pads 121 are fixedly connected to the periphery of the connecting portion 120 .

[0043] Meanwhile, the rotating flange 300 is also allowed to include an upper clamping portion 320, which is located above the positioning flange 100. A plurality of third gear teeth 321 are evenly arranged on the upper clamping portion 320, and the number of the third gear teeth 321 is the same as that of the guide pad 121, and is located on one side of the guide pad 121. When the rotating flange 300 is rotating, the third gear teeth 321 can limit the rotation of the rotating flange 300 through the guide pad 121.

[0044] A clamping area is formed between the upper clamping portion 320 and the lower clamping portion 310, and the positioning portion 110 and the first gear 21 are allowed to be clamped in the clamping area. Therefore, when the rotating flange 300 rotates a certain angle, the clamping limit of the positioning portion 110 and the first gear 210 can be released or executed.

[0045] Furthermore, a first wedge block 340 is provided on the lower clamping portion 310 of the rotating flange 300, and the first wedge block 340 is located on the second gear tooth 311, and a second wedge block 350 is provided on the first gear tooth 210. The first wedge block 340 and the second wedge block 350 are in opposite directions and can be matched. Therefore, when the rotating flange 300 is rotating, the rotating flange 300 rotates a distance between teeth, so that the rotating flange 300 overlaps or staggers with the cover flange 200. And, by the mutual matching between the first wedge block 340 and the second wedge block 350, the connection strength between the cover flange 200 and the positioning flange 100 is improved.

[0046] See also Figure 1 In one embodiment, a first driving member 230 and a second driving member 330 are further provided. The first driving member 230 is used to drive the cover flange 200 to separate or close the positioning flange 100, and the second driving member 330 is used to drive the rotating flange 300 to rotate.

[0047] For example, in one embodiment, the first driving member 230 includes a telescopic cylinder 231, a first connecting frame 232, and a rotating frame 233. The cylinder body of the telescopic cylinder 231 is hingedly arranged with the tube body of the extraction tank, and the lever of the telescopic cylinder 231 is hingedly arranged with one end of the rotating frame 233. The first connecting frame 232 is fixedly connected to the tank body 10 of the extraction tank, and the middle part of the rotating frame 233 is pivotally connected to the first connecting frame 232. The other end of the rotating frame 233 is connected to the cover flange 200. Therefore, after the rotating flange 300 is released from the constraints of the cover flange 200 and the positioning flange 100, it is allowed to drive the cover flange 200 to separate from the positioning flange 100 through the telescopic cylinder 231.

[0048] And, in one embodiment, the second driving member 330 includes a rotating cylinder 331 and a second connecting frame 332. The second connecting frame 332 is fixedly connected to the tank body 10 of the extraction tank, and the rotating cylinder 331 is located on the second connecting frame 332. The rotating flange 300 is drivingly connected to the rotating cylinder 331, so that the rotating flange 300 is driven to rotate by the rotating cylinder 331.

[0049] See also Figure 1 In one embodiment, the extraction tank disclosed in the utility model further includes a liquid outlet pipe assembly 11 and a steam backflush assembly 12, and the liquid outlet pipe assembly 11 and the steam backflush assembly 12 are respectively connected to the tank body 10 of the extraction tank. Therefore, in actual use, the extract is fed into the feeding hole at the top of the extraction tank, and then a solvent is added for extraction. After the extraction is completed, the liquid is discharged through the liquid outlet pipe assembly 11. After the liquid is discharged, the steam backflush assembly 12 is used to fluff up the medicinal materials in the liver, which is helpful for unloading.

[0050] In summary, the utility model discloses a slag discharge door structure of an extraction tank and an extraction tank using the same. When the cover flange 200 and the positioning flange 100 are fitted, the rotating flange 300 is connected between the positioning flange 100 and the cover flange 200 to ensure a tight connection between the cover flange 200 and the positioning flange 100. At the same time, since the gap between the teeth of the adjacent second gear teeth 311 is greater than the tooth width of the first gear teeth 210, in the actual connection process, the second gear teeth 311 on the cover flange 200 can be allowed to pass through the gap between the adjacent second gear teeth 311 on the rotating flange 300 to connect with the positioning flange 100. The rotating flange 300 is driven to rotate so that the cover flange 200 and the positioning flange 100 are quickly and tightly connected. On the contrary, the cover flange 200 and the positioning flange 100 can be quickly separated.

[0051] Therefore, the problem that the door 220 at the slag discharge port of the existing extraction tank is complicated to open and close during use and is not easy to quickly discharge slag can be effectively improved. Therefore, the utility model effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
