Description

Technical Field

[0001] This invention relates to the field of water pumping equipment technology, and in particular to a yellow water extraction mechanism for a microbial fermentation tank of strong-aroma baijiu. Background Technology

[0002] Yellow water is a brownish-yellow, slightly viscous, turbid liquid produced during the solid-state fermentation of baijiu. It contains a large amount of nitrogenous compounds, reducing sugars, and aromatic substances such as alcohols, aldehydes, acids, and esters, as well as beneficial microbial flora. Yellow water can be used for blending baijiu, maintaining cellars, cultivating artificial cellar mud, and mixing mash for fermentation in cellars.

[0003] To facilitate the recycling of yellow water, a yellow water storage tank is pre-dug at the bottom of the fermentation tank. A cover with a filtration function is installed above the yellow water storage tank, and a connecting pipe is vertically installed inside the yellow water storage tank to connect to it. In the existing technology, the yellow water is extracted by connecting the connecting pipe to the extraction mechanism (pump) through a pipe joint, and then the yellow water is extracted by the extraction device. However, in actual production activities, due to the different sizes of fermentation tanks, the size of the yellow water storage tank and the size of the connecting pipe used are also different. In the existing technology, the pipe joint of the extraction mechanism is often of a single size. If it is necessary to perform water extraction operations on storage tanks of different sizes, it is necessary to change the matching joint according to the size of the connecting pipe. It can be seen that the existing extraction mechanism has a single pipe joint size, which cannot meet the needs of connecting pipes of different sizes, and therefore cannot meet the needs of extracting yellow water from yellow water storage tanks of different specifications, resulting in low flexibility of use. Summary of the Invention

[0004] In view of the problems existing in the yellow water extraction mechanism of the microbial fermentation tank of strong-aroma baijiu, the present invention proposes a yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu to solve such problems.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a yellow water extraction mechanism for a microbial fermentation tank of strong-aroma baijiu, comprising an extraction unit and a docking unit, wherein the docking unit comprises a sleeve component with a circular tube structure, a main drive component threadedly connected to the sleeve component, a fixing component rotatably connected below the main drive component and extending to the inside of the sleeve component, a docking component inserted into the inside of the sleeve component, and a secondary drive component threadedly connected to the upper end of the sleeve component; The docking component includes a sleeve inserted into the sleeve component, a conical head fixedly disposed at the lower end of the sleeve, the conical head having a conical structure that is thinner at the bottom and thicker at the top, multiple sets of auxiliary rods equally disposed on the outer wall of the sleeve, with the top of the auxiliary rods extending outward to the outside of the sleeve component, a connecting shaft disposed at the top of each set of auxiliary rods, the connecting shaft extending upward into the secondary drive component, and a sealing sleeve disposed on the outer wall of the conical head.

[0006] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the sleeve component includes a lower sleeve located at the lower end, a lower threaded pipe opened on the outer wall of the upper end of the lower sleeve, and the main drive component is threadedly connected to the lower threaded pipe, as well as multiple sets of inclined grooves equally opened on the lower sleeve.

[0007] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the sleeve component further includes an upper sleeve disposed at the top of the lower sleeve, an upper thread formed on the outer wall of the lower end of the upper sleeve, and a secondary drive component threadedly connected to the upper thread, as well as multiple sets of clearance grooves formed on the upper thread, and multiple sets of auxiliary rods correspondingly inserted into the multiple sets of clearance grooves.

[0008] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the upper end of the inclined trough is provided with a guide edge that slopes inward from the outer wall of the lower sleeve, and a guide block is provided below the inclined trough, with the top of the guide block being smooth and sloping inward.

[0009] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the main driving component includes a main collar sleeved on the lower threaded pipe, a main lever arranged laterally on the side of the main collar, and a limiting ring arranged at the lower end of the main collar, and the top end of the fixing component is sleeved on the limiting ring.

[0010] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the fixing component includes a connecting ring sleeved on the lower end of the limiting ring, multiple sets of fixing rods equally distributed around the connecting ring, a sliding groove opened in the fixing rod, a limiting shaft set in the sliding groove and fixedly connected to the inclined groove, and a clamping block set at the end of the fixing rod.

[0011] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the fixing rod extends downward into the inclined groove, the clamping block is attached to the inner wall of the sleeve component, and the clamping block is parallel to the sleeve component. At the same time, multiple sets of transversely arranged limiting strips are vertically distributed on the inner side of the clamping block.

[0012] As a preferred embodiment of the yellow water extraction mechanism for the microbial fermentation tank of strong-aroma baijiu described in this invention, the auxiliary driving component includes a secondary collar threadedly connected to the upper sleeve, a secondary lever laterally disposed on the outside of the secondary collar, and a connecting groove opened on the bottom surface of the secondary lever, with the connecting shaft extending into the connecting groove.

Furthermore, by setting the main drive component and the fixing component, the docking unit is firmly fixed to the yellow water pipe, which fully ensures the connectivity between the docking unit and the yellow water pipe. In addition, the main drive component and the fixing component can also adaptively adjust the fixing range according to the actual size of the yellow water pipe, so that the docking unit can be fixed on yellow water pipes of different sizes and specifications, further enhancing the flexibility of use. Furthermore, by setting up a docking component and a secondary drive component to assist the conical head in docking with the yellow water pipe, and setting a sealing sleeve on the outer wall of the conical head, the secondary drive component will push the conical head into the yellow water pipe through the docking component during use. During the pushing process, the sealing sleeve located on the outer wall of the conical head will deform at the connection between the conical head and the yellow water pipe under the action of the pushing force of the secondary drive component and the reverse force of the yellow water pipe, thereby sealing and filling the gap between the two and strengthening the sealing performance of the connection.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Reference Figures 1 to 8This invention provides an embodiment of a yellow water extraction mechanism for a microbial fermentation tank of strong-aroma baijiu. The mechanism includes an extraction unit 1 and a docking unit 2. The docking unit 2 includes a sleeve component 21 with a circular tube structure, a main drive component 22 threadedly connected to the sleeve component 21, a fixing component 23 rotatably connected below the main drive component 22 and extending its bottom end into the sleeve component 21, a docking component 24 inserted into the sleeve component 21, and a secondary drive component 25 threadedly connected to the upper end of the sleeve component 21. The extraction unit 1 is a common extraction device. The docking unit 2 is used to dock with a yellow water pipe 3. The sleeve component 21 is directly sleeved on the outside of the yellow water pipe 3. The main drive component 22 pushes the fixing component 23 to fix the yellow water pipe 3 to the yellow water pipe 3, and the secondary drive component 25 pushes the docking component 24 to dock the docking component 24 with the yellow water pipe 3. Reference Figure 6 and Figure 7 The docking component 24 includes a sleeve 241 inserted into the sleeve component 21, a conical head 242 fixedly disposed at the lower end of the sleeve 241, the conical head 242 having a conical structure that is thinner at the bottom and thicker at the top, multiple sets of auxiliary rods 243 equally distributed on the outer wall of the sleeve 241, with the top of the auxiliary rods 243 extending outward to the outside of the sleeve component 21, a connecting shaft 244 disposed at the top of each set of auxiliary rods 243, the connecting shaft 244 extending upward into the auxiliary drive component 25, and a sealing sleeve 245 disposed on the outer wall of the conical head 242. The conical head 242 is the part that docks with the yellow water pipe 3, and its conical structure includes multiple straight sections in the vertical direction. The diameter of the conical head 242 allows it to accommodate different sizes of yellow water pipes 3 for connection. The auxiliary rod 243 and connecting shaft 244, through their connection with the secondary drive component 25, enable the secondary drive component 25 to move synchronously with the connection component 24, resulting in a tighter connection between the connection component 24 and the yellow water pipe 3. The sealing sleeve 245 on the outer wall of the conical head 242 deforms at the connection point between the conical head 242 and the yellow water pipe 3 when the secondary drive component 25 pushes the conical head 242 into the yellow water pipe 3, under the combined force of the pushing force of the secondary drive component 25 and the opposing force of the yellow water pipe 3. Figure 8 As shown in the figure, this seals and fills the gap between the two, thus strengthening the sealing of the connection between them.

[0027] Furthermore, refer to Figure 4 The sleeve component 21 includes a lower sleeve 211 located at the lower end, a lower threaded tube 213 opened on the outer wall of the upper end of the lower sleeve 211, and a main drive component 22 threadedly connected to the lower threaded tube 213, as well as multiple sets of inclined grooves 214 equally opened on the lower sleeve 211. The main drive component 22 can move vertically on the sleeve component 21 through threaded engagement with the lower threaded tube 213, while the inclined grooves 214 are used to install the fixing rod 232.

[0028] Furthermore, refer to Figure 4 The sleeve component 21 also includes an upper sleeve 212 disposed at the top of the lower sleeve 211, an upper thread 215 formed on the outer wall of the lower end of the upper sleeve 212, and a secondary drive component 25 threadedly connected to the upper thread 215, as well as multiple sets of clearance grooves 216 formed on the upper thread 215, and multiple sets of auxiliary rods 243 correspondingly inserted into the multiple sets of clearance grooves 216. The secondary drive component 25 can make vertical displacement on the upper sleeve 212 through the threaded engagement with the upper thread 215, while the clearance grooves 216 are used to make way for the connecting shaft 244.

[0029] Furthermore, refer to Figure 5 The upper end of the inclined groove 214 is provided with a guide edge 2141 that slopes inward from the outer wall of the lower sleeve 211. The lower part of the inclined groove 214 is provided with a guide block 2142, and the top of the guide block 2142 is smooth and slopes inward. The inclined arrangement of the guide edge 2141 and the guide block 2142 can limit the initial state of the fixing rod 232, so that the fixing rod 232 always extends towards the axis of the sleeve component 21 in an inclined posture.

[0030] Furthermore, refer to Figure 3 The main drive component 22 includes a main collar 221 sleeved on the lower threaded tube 213, a main lever 222 laterally disposed on the side of the main collar 221, and a limiting ring 223 disposed at the lower end of the main collar 221. The top end of the fixing component 23 is sleeved on the limiting ring 223. The main collar 221 is connected to the fixing component 23 through the limiting ring 223. The main drive component 22 and the fixing component 23 do not interfere with each other in the circumferential direction. However, the main drive component 22 is threadedly connected to the lower sleeve 211 through the lower threaded tube 213 in the vertical direction. Therefore, the main drive component 22 can drive the fixing component 23 to move in the vertical direction, thereby realizing the action of driving the fixing component 23 to perform limiting clamping. The main lever 222 is used to assist the main drive component 22 in rotation adjustment.

[0031] Furthermore, refer to Figure 3The fixing component 23 includes a connecting ring 231 sleeved on the lower end of the limiting ring 223, multiple sets of fixing rods 232 evenly distributed around the connecting ring 231, a sliding groove 233 formed in the fixing rod 232, a limiting shaft 234 set in the sliding groove 233 and fixedly connected in the inclined groove 214, and a clamping block 235 set at the end of the fixing rod 232. The fixing component 23 is rotatably connected to the lower part of the main drive component 22 through the connecting ring 231, and can move vertically with the main drive component 22 without affecting the rotation of the main drive component 22. The vertically moving connecting ring 231 will synchronously push the fixing rod 232 to move, and the limiting shaft 234 will move vertically. 4. Since it is set in the inclined groove 214, the limiting shaft 234 and the connecting ring 231 can insert the fixing rod 232 into the inclined groove 214 in an inclined posture. When the connecting ring 231 moves downward, it will push the fixing rod 232 downward in an inclined manner and towards the axis of the sleeve component 21. The four sets of fixing rods 232 move synchronously and eventually form an inward clamping action. When the extraction work is performed, the sleeve component 21 is put on the yellow water pipe 3, so that the yellow water pipe 3 is located between the four sets of fixing rods 232. At this time, the fixing rods 232 that are clamped inward will clamp the yellow water pipe 3 located in the sleeve component 21, thereby making the docking unit 2 and the yellow water pipe 3 tightly connected.

[0032] Furthermore, refer to Figure 3 The fixing rod 232 extends downward into the inclined groove 214. The clamping block 235 is attached to the inner wall of the sleeve component 21 and is parallel to the sleeve component 21. At the same time, multiple sets of horizontally arranged limiting strips are vertically distributed on the inner side of the clamping block 235. The two sides of the fixing rod 232 are attached to the guide edge 2141 and the guide block 2142 respectively. Therefore, due to the limitation of the two, the fixing rod 232 will move in an inclined posture under the limitation of the two. The multiple sets of horizontally arranged limiting strips on the clamping block 235 can increase the vertical friction between the clamping block 235 and the yellow water pipe 3.

[0033] Furthermore, refer to Figure 3The auxiliary drive component 25 includes an auxiliary collar 251 threaded onto the upper sleeve 212, an auxiliary lever 252 laterally disposed on the outside of the auxiliary collar 251, and a connecting groove 253 formed on the bottom surface of the auxiliary lever 252. The connecting shaft 244 extends into the connecting groove 253. The auxiliary lever 252 can drive the auxiliary collar 251 to rotate on the upper sleeve 212. The rotating auxiliary collar 251 can rotate and move vertically at the same time under the action of the thread. When the auxiliary drive component 25 rotates, it maintains the connection with the docking component 24 through the connecting groove 253. Through the cooperation between the connecting groove 253 and the docking component 24, the docking component 24 will only move vertically and will not rotate circumferentially. By pushing the docking component 24 to move vertically, the conical head 242 can be pushed closer to the yellow water pipe 3, thereby increasing the intimacy of the connection between the two.

[0034] Furthermore, refer to Figure 1 A connecting pipe 11 connects the extraction unit 1 and the docking unit 2. A water outlet 12 is provided on the side of the extraction unit 1. The water outlet 12 is used to extract yellow water and discharge it to the outside. An auxiliary pipe can be connected according to actual needs.

[0035] Furthermore, refer to Figure 3 The connecting pipe 11 is internally connected to the docking component 24, and the sleeve 241 is internally connected to the conical head 242. The connecting pipe 11 can extract and transport yellow water through the docking component 24.

[0036] In summary, during the extraction of yellow water, the fitting component 21 is fitted onto the yellow water pipe 3, and the conical head 242 is initially inserted into the yellow water pipe 3. Then, the main drive component 22 is rotated to drive the fixing component 23 to work. The fixing component 23 uses four sets of fixing rods 232 and corresponding clamping blocks 235 to hold the yellow water pipe 3 in a ring, thereby fixing the docking unit 2 to the yellow water pipe 3 as a whole. This fully ensures the connectivity between the docking unit 2 and the yellow water pipe 3. At the same time, the ringing range of the fixing component 23 can be adjusted according to the actual size of the yellow water pipe 3, thus enabling the docking unit 2 to be fixed on yellow water pipes 3 of different sizes and specifications, further enhancing the flexibility of use. After the docking unit 2 is fixed on the yellow water pipe 3, the docking component 24 is moved vertically inside the sleeve component 21 by rotating the secondary drive component 25. At this time, both the sleeve component 21 and the yellow water pipe 3 remain stationary. During the movement of the docking component 24, the conical head 242 of the conical structure will be further inserted into the yellow water pipe 3. During the insertion process, the sealing sleeve 245 will deform at the connection between the conical head 242 and the yellow water pipe 3 under the action of the pushing force of the secondary drive component 25 and the opposing force of the yellow water pipe 3 (e.g., Figure 8As shown), the gap between the two is sealed and filled to enhance the sealing of the connection. The conical head 242 of the conical structure has multiple diameters in the vertical direction, which allows the conical head 242 to meet the docking work of yellow water pipes 3 of different sizes. This enables the mechanism to meet the needs of extracting yellow water from yellow water storage tanks of different specifications. After the docking unit 2 completes the docking work, the extraction unit 1 is started to extract the yellow water. At this time, the extraction unit 1 will extract the yellow water in the fermentation tank through the connection of the connecting pipe 11, the docking unit 2 and the yellow water pipe 3, and discharge it outward through the outlet 12, thereby achieving the purpose of extracting yellow water.
