Description

Technical Field

[0001] This invention relates to the field of automatic preparation equipment for sealing mud, specifically an automatic preparation system for sealing mud used in the production of baijiu (Chinese liquor). Background Technology

[0002] In the process of baijiu production, cellar mud plays a very important role. The sealing mud can effectively ensure the stability of the fermentation environment of baijiu, provide good moisture retention, and also provide assistance to the fermenting baijiu for microorganisms. The current method of preparing sealing mud is to use high-quality loess, which is crushed, filtered to remove stones and sand, and then dried to obtain clean loess powder. Then it is put into a cellar mud mixer to mix functional bacterial liquid and nutrient liquid until it is evenly mixed and fermentation is carried out to complete the preparation of sealing mud.

[0003] According to the existing Chinese patent CN116286235A, an automatic preparation device and its operation method for sealing mud in baijiu production belong to the technical field of baijiu cellar mud preparation equipment. It includes a mud conveyor belt, a spray pipe, belt-type spiral stirring blades, spiral stirring and conveying blades, a mud mixing container, a mud unloading handle, and a mud unloading port. The mud mixing container has an opening at the top and a mud unloading port on the bottom right side. The discharge end of the mud conveyor belt is installed above the mud mixing container. The spray pipe is located on the front and rear sides of the top of the mud mixing container. The belt-type spiral stirring blades and spiral stirring and conveying blades are arranged in two horizontal pairs, arranged from top to bottom in the mud mixing container and rotatably connected to it. Both the belt-type spiral stirring blades and spiral stirring and conveying blades are connected to a power mechanism. This invention can reduce the labor intensity in the sealing mud preparation process, improve the stability and uniformity of the sealing mud quality, facilitate quality control and production standardization, and improve the utilization rate of the sealing mud.

[0004] According to the existing Chinese patent CN219356066U, a pit sludge mixing machine relates to the field of mixing machine technology. The pit sludge mixing machine includes a support frame, a hopper, a mixing mechanism, and a power mechanism. The hopper is connected to the support frame and has a water inlet assembly inside. The mixing mechanism is located inside the hopper and includes two sets of vertically parallel spiral blades with opposite inclination directions. The power mechanism is connected to the support frame and drives the two sets of spiral blades. This invention improves the mixing effect by connecting the power mechanism to the mixing mechanism. The mixing mechanism includes two sets of spiral blades arranged inside the hopper and rotating in opposite directions. While breaking up the pit sludge, the two sets of spiral blades drive the pit sludge upwards or downwards, forming a circulation. The water inlet assembly injects water into the hopper. The water and the broken pit sludge are mixed under the circulating mixing of the two sets of spiral blades.

[0005] As disclosed in the aforementioned patent, the structure of existing mud mixing equipment is the same as that of the aforementioned equipment. It performs mixing by setting up a stirring shaft. However, in actual production, we know that when the existing mud mixing equipment feeds yellow clay (mostly using belt conveyors for feeding), the yellow clay falling into the mixing tank will raise a large amount of dust. The dust flying around the factory area will have a significant impact on the air environment and equipment. If dust collection equipment is installed in the factory for dust removal and adsorption, the collected yellow clay dust still needs to be manually cleaned and removed after a certain amount is collected, or manually removed and put into the mixing tank for remixing. Although the dust removal effect can be achieved, the operation is very cumbersome and requires many manual steps.

[0006] Therefore, it is necessary to provide an automated system for preparing sealing mud for baijiu production to solve the above-mentioned technical problems. Summary of the Invention

[0020] (III) Beneficial Effects

[0021] This invention provides an automated system for preparing sealing mud for baijiu (Chinese liquor) production. Compared with existing technologies, it has the following advantages:

[0022] 1. The automatic preparation system for sealing mud in baijiu production provided in this application can effectively prevent dust generation by adsorbing the dust through a dust removal component when a lot of dust is generated from the yellow clay during feeding. After the dust removal and adsorption are completed, the system can use a moving mechanism and a water spray component to spray the bacterial solution into the mixing tank. At the same time as spraying, the dust filter part of the dust removal component can be cleaned. The bacterial solution washes down the filtered dust into the mixing tank. Compared with traditional baijiu mud mixing equipment, this system avoids dust generation. Compared with traditional dust removal equipment, it eliminates the need for frequent manual cleaning of the adsorbed dust. It can automatically wash after adsorption is completed, and the washed-down dust can be mixed. This greatly saves the steps of manual operation, saves manpower, and is more convenient to use.

[0023] 2. During the mixing process, this application can evenly spray the bacterial solution into the loess, making the mixing of loess and bacterial solution more uniform, improving the quality of mixing, reducing the probability of some loess not being mixed with bacterial solution, ensuring uniform fermentation of loess in the later stage, and because the dust raised by the loess can be effectively collected and mixed into the loess for continued use, it effectively saves loess and avoids loess scattering and loss.

[0024] 3. After the mixing and stirring are completed and the materials are discharged, this application can also use a moving mechanism and a water spraying component to evenly spray the clean water in the bacterial liquid tank into the mixing tank for automatic cleaning, without the need for manual cleaning, which is convenient to use.

[0025] 4. Because the water source switching of the spray component is mechanically linked to the opening and closing of the cover, the water source can be automatically switched to the bacterial solution tank when the cover is opened. Then, the rotation of the stirring component causes the ribbon stirring shaft to rotate, and the moving spray component sprays clean water evenly on all sides of the mixing tank. The rotation of the ribbon stirring shaft also ensures that the water is sprayed evenly. The mechanical linkage ensures the timeliness of water source switching, eliminating the need for separate electrical control equipment and reducing the probability of switching delays.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figures 1 to 15 and Figure 17 This invention provides a technical solution: an automatic preparation system for sealing mud in baijiu production, comprising a stirring tank 1, a stirring assembly 101 installed in the stirring tank 1, a cover plate 102 rotatably connected to the bottom of the stirring tank 1 via a pivot pin, the cover plate 102 being in contact with the bottom surface of the stirring tank 1, and the cover plate 102 further comprising two electric push rods 1021 symmetrically rotatable on its two outer walls via pivot pins, the upper ends of the electric push rods 1021 being rotatably connected to the outer wall of the stirring tank 1 via pivot pins, the electric push rods 1021 being extended when the cover plate 102 is opened, thereby causing the cover plate 102 to rotate open, and the electric push rods 1021 being retracted when the cover plate 102 is closed, thereby pulling the cover plate 102 closed;

[0047] A dust removal component 2 for removing dust during the feeding of yellow mud is fixed on the outer wall of the mixing tank 1. A frame 3 is provided on one side of the mixing tank 1, and a water tank 4 is fixed on the frame 3. A bacterial liquid tank 401 and a clear water tank 402 are formed on the water tank 4. A water supply pipe 5 is connected to the outer wall of the water tank 4, and a water spray component 6 is installed at the end of the water supply pipe 5. The water spray component 6 is slidably connected to the top of the frame 3. A moving mechanism 7 for driving the water spray component 6 to reciprocate is also installed on the frame 3. The input end of the moving mechanism 7 is fixed to the mixing component 101. The output end of the moving mechanism 7 is fixed to the water spray assembly 6. The water spray assembly 6 can automatically clean the dust removal assembly 2 during movement. The water supply pipe 5 has a first state connected to the bacterial liquid tank 401 and a second state connected to the clean water tank 402. An automatic switching assembly 8 for switching the first and second states of the water supply pipe 5 is also installed on the frame 3. The input end of the automatic switching assembly 8 is connected to the cover plate 102. When the cover plate 102 is open, the water supply pipe 5 is in the first state. When the cover plate 102 is closed, the water supply pipe 5 is in the second state.

[0048] During operation, a belt conveyor transports the loess to the mixing tank 1. A large amount of dust is generated during material feeding, so the dust removal component 2 is activated to absorb the dust and prevent it from scattering. After feeding, the dust removal component 2 is stopped, and the mixing component 101 is driven to mix the loess. Simultaneously, the moving mechanism 7 moves the water spray component 6 back and forth. This back-and-forth movement of the water spray component 6 draws in the bacterial solution from the clear water tank 402 and sprays it evenly into the mixing tank 1, ensuring the loess and bacterial solution are evenly mixed. During spraying, the water spray component 6 automatically... The dust filtered by the dust removal component 2 is flushed to achieve automatic cleaning, eliminating the need for manual cleaning of the dust removal structure, saving manpower and making it more convenient to use. When the cover plate 102 is opened to discharge materials after mixing, the water source of the water spray component 6 is switched from the clean water tank 402 to the bacterial liquid tank 401 at the same time as the cover is opened. After the material is discharged, the stirring component 101 is driven to work. At this time, the water spray component 6 sprays clean water evenly into the stirring tank 1 for automatic cleaning, further saving manpower and eliminating the need for manual cleaning. Moreover, the switching of the water source and the opening and closing of the cover plate 102 are mechanically linked to ensure the timeliness and stability of the switching.

[0049] The stirring assembly 101 includes a ribbon stirring shaft 1011 and a motor 1012. The ribbon stirring shaft 1011 is rotatably connected to the inner wall of the stirring tank 1 via bearings. One end of the ribbon stirring shaft 1011 extends through the stirring tank 1 to the outer wall of the stirring tank 1. A motor 1012 is fixed to the outer wall of the stirring tank 1. The motor 1012 is a geared motor 1012. The output end of the motor 1012 is fixed to the end of the ribbon stirring shaft 1011. During stirring, the motor 1012 drives the ribbon stirring shaft 1011 to rotate, stirring the loess mud raw material in the stirring tank 1, so that the loess and bacterial solution are fully mixed. The motor 1012 stops working when the stirring ends. When the cover plate 102 is opened to discharge the material, the motor 1012 is driven to rotate again, causing the ribbon stirring shaft 1011 to rotate and disturb the material so that the material can be discharged smoothly. It should be emphasized that when the motor 1012 rotates, the water spray component 6 sprays a certain amount of water into the mixed material. A small amount of water will not affect the material. The water content of the bacterial solution can be adjusted to ensure that the material will not be affected when a certain amount of water is added again during mixing and discharge, until the material is completely discharged. Then the motor 1012 continues to rotate, the ribbon stirring shaft 1011 idles, and the water spray component 6 sprays clean water evenly into the mixing tank 1 to clean the inner wall of the mixing tank 1 and the ribbon stirring shaft 1011.

[0050] The dust removal assembly 2 includes a dust collection hood 21, which is fixed above the mixing tank 1. An air pump 22 is fixed to the outer wall of the dust collection hood 21. The air inlet of the air pump 22 is connected to the dust collection hood 21, and the air outlet of the air pump 22 is connected to a connecting box 23 via a rigid air supply pipe. The connecting box 23 has openings at the top and bottom. A filter screen 24 is fixed to the upper end of the inner wall of the connecting box 23. A first rotating shaft 25 is rotatably connected to the lower end of the outer wall of the connecting box 23 via a bearing. The bottom of the first rotating shaft 25... A sealing plate 26 is fixed, which contacts the bottom of the connecting box 23. A torsion spring 27 is sleeved on the outer side of the first rotating shaft 25. One end of the torsion spring 27 is fixed to the outer wall of the first rotating shaft 25, and the other end of the torsion spring 27 is fixed to the outer wall of the connecting box 23. A blocking block 28 is also fixed on the outer wall of one side of the connecting box 23. The sealing plate 26 is pressed against the outer wall of the blocking block 28 under the action of the rebound force of the torsion spring 27. A vertical rod 29 is fixed to the end of the sealing plate 26 away from the connecting box 23.

[0051] When dust removal is in operation, the air pump 22 is driven to work, so that the dust is sucked into the air pump 22 at the dust collection hood 21 and then enters the connecting box 23 through the rigid air delivery pipe. When feeding, the water spray component 6 is located at the end position above the mixing tank 1. Therefore, when dust removal is in operation, the bottom opening of the connecting box 23 is sealed by the sealing plate 26. Thus, the air containing dust enters the inside of the connecting box 23 and overflows from the filter screen 24 above. The dust is blocked on the filter screen 24, achieving the filtration effect.

[0052] The water spray assembly 6 includes a movable component 61. The top of the frame 3 is slidably connected to the movable component 61 via a linear slide rail. A sleeve 62 is fixed to the top of the movable component 61. A piston 63 is slidably inserted into the inner wall of the sleeve 62. A T-shaped component 64 is fixed to one end of the piston 63. The T-shaped component 64 is slidably connected to the sleeve 62 via a sliding hole. A liquid inlet check valve 65 is fixed to the side wall of the sleeve 62 away from its open end. The end of the water supply pipe 5 is connected to the liquid inlet... A one-way valve 65 is connected to the sleeve 62. A liquid outlet one-way valve 66 is fixed to the end of the sleeve 62 away from its open end. A water spray pipe 67 is fixed to the liquid outlet end of the liquid outlet one-way valve 66. A crossbar 68 is fixed to the upper end of the moving part 61 near the stirring tank 1. The end of the water spray pipe 67 away from the liquid outlet one-way valve 66 is fixed to the outer wall of the crossbar 68. Multiple nozzles 69 are equidistantly connected to the end of the water spray pipe 67 near the crossbar 68. The nozzles 69 are fixed to the outer wall of the crossbar 68. The end of the movable component 61 furthest from the mixing tank 1 is rotatably connected to a second rotating shaft 610 via a bearing. A turntable 611 is fixed to the upper end of the second rotating shaft 610, and a drive column 612 is fixed to the turntable 611. The upper end of the drive column 612 is inserted into a transverse groove 641 at the end of the T-shaped component 64. A gear 613 is fixed to the bottom of the second rotating shaft 610, passing through the movable component 61. A rack 614 is fixed to the frame 3 at a position corresponding to the gear 613. 14 is meshed with gear 613. The water spray assembly 6 also includes a push assembly 615 mounted on the crossbar 68 for driving the sealing plate 26 to rotate and open. The push assembly 615 includes a drive bar 6151 rotatably connected to the outer wall of the crossbar 68 by a shaft pin. The outer wall of the drive bar 6151 is in contact with the outer wall of the crossbar 68. The side of the drive bar 6151 away from the crossbar 68 is arc-shaped. The drive bar 6151 is directly opposite the vertical bar 29.

[0053] When the stirring assembly 101 is working, it can synchronously drive the moving mechanism 7 to work, so that the water spray assembly 6 moves back and forth on the frame 3. When the water spray assembly 6 moves, the gear 613 is driven to rotate by the rack 614, which makes the second rotating shaft 610 rotate, thereby making the turntable 611 rotate. Through the drive column 612, the T-shaped part 64 slides back and forth, continuously pulling and pushing the piston 63. The piston 63 slides out of the sleeve 62, the liquid inlet check valve 65 opens and the liquid outlet check valve 66 closes. The liquid in the bacterial liquid tank 401 or the clear water tank 402 is sucked into the sleeve 62 through the water supply pipe 5. The piston 63 slides into the sleeve 62, the liquid outlet check valve 66 opens and the liquid inlet check valve 65 closes, pushing the liquid in the sleeve 62 from the water spray pipe 67 into the nozzle 69 and spraying it into the stirring tank 1.

[0054] As the water spray assembly 6 moves toward the side closer to the motor 1012, the drive bar 6151 gradually approaches the vertical rod 29 until its arc-shaped side abuts against the outer wall of the vertical rod 29. Then, as the drive bar 6151 moves, it pushes the vertical rod 29, causing the sealing plate 26 to rotate around the axis of the first rotating shaft 25. The sealing plate 26, the first rotating shaft 25, and the vertical rod 29 rotate simultaneously around the axis of the first rotating shaft 25. Simultaneously, the torsion spring 27 is twisted, causing the sealing plate 26 to separate from the blocking block 28. The sealing plate 26 opens the lower opening of the connecting box 23 until it reaches its maximum angle. Afterward, the drive bar 6151 continues to move, offsetting from the vertical rod 29. Then, under the rebound force of the torsion spring 27, the sealing plate 26 returns to its original position and abuts against the blocking block 28, sealing the bottom opening of the connecting box 23. This continues until the water spray assembly 6 reaches a position close to the motor 1012, then turns back and gradually moves away. During the process of motor 1012, the drive bar 6151 contacts the vertical rod 29. Due to the obstruction of the vertical rod 29, the drive bar 6151 will flip upward relative to the horizontal rod 68 to avoid the vertical rod 29. When the water spray assembly 6 moves to the side closer to motor 1012 again, the sealing plate 26 will open again. Each time the sealing plate 26 is opened, the nozzle 69 will spray bacterial liquid or clean water onto the filter screen 24. The bacterial liquid or clean water flows through the filter screen 24, carrying away the dust attached to the filter screen 24 and flowing into the connecting box 23. After each opening of the sealing plate 26, the bacterial liquid or clean water with dust will flow out into the mixing tank 1. This process is repeated continuously to automatically clean the filter screen 24. The cleaned loess dust will continue to enter the mixing and stirring work, which greatly saves manpower, is convenient to use, and reduces the loss of loess, thus saving the amount of loess used.

[0055] The moving mechanism 7 includes a reciprocating lead screw 71. The reciprocating lead screw 71 is rotatably connected to the frame 3 directly below the moving part 61 via a bearing. A moving block 72 is fitted on the outer side of the reciprocating lead screw 71. The top of the moving block 72 is fixed to the outer wall of the moving part 61. Synchronous pulleys 73 are fixed to the end of the reciprocating lead screw 71 and the output end of the motor 1012. A synchronous belt 74 is connected between the two synchronous pulleys 73. When the stirring operation is in progress, the output shaft of the motor 1012 rotates, driving the synchronous pulleys 73 to rotate, which causes the reciprocating lead screw 71 to rotate, thereby causing the moving block 72 to drive the moving part 61 to slide back and forth on the frame 3.

[0056] Example 2

[0057] Please see Figures 1 to 15The automatic switching component 8 includes a sliding bar 81. An inclined sliding bar 81 is slidably mounted on the frame 3, with its lower end facing the cover plate 102. A flip bar 82 is rotatably connected to the lower end of the sliding bar 81 via a pivot pin. Two connecting rods 83 are symmetrically fixed to the side of the cover plate 102 near the flip bar 82. The end of the flip bar 82 is rotatably connected to the two connecting rods 83 via a pivot pin. Two through holes 84 are symmetrically opened at the lower end of the water tank 4 near the sliding bar 81. The two through holes 84 are respectively connected to the bacterial solution tank 401 and the clear water tank 402. The outer wall of the water tank 4 near the through holes 84... Two connecting strips 85 are symmetrically fixed, and a sealing strip 86 is slidably nested between the two connecting strips 85. The sealing strip 86 is in contact with the outer wall of the water tank 4 by compression. A connecting port 87 is formed on the sealing strip 86, and the connecting port 87 corresponds to a through hole 84. The end of the water supply pipe 5 is fixed to the inner wall of the connecting port 87. An inclined plate 88 is fixed on the outer wall of the sealing strip 86. The inclined plate 88 has the same inclination angle as the sliding strip 81. A driving groove 89 is opened on the inclined plate 88. A pushing column 810 is fixed to the end of the sliding strip 81 and is inserted into the driving groove 89.

[0058] When the cover plate 102 is opened, the cover plate 102 rotates around the axis of its connection with the mixing tank 1, and the two connecting rods 83 rotate simultaneously, pushing the flip bar 82, which in turn pushes the sliding bar 81 to slide towards the side closer to the water tank 4, so that the pushing column 810 pushes the driving groove 89, so that the inclined plate 88 drives the sealing bar 86 to slide, so that the connecting port 87 on the sealing bar 86 slides and aligns with another through hole 84, and the remaining through hole 84 is blocked by the sealing bar 86, completing the switching of the water source at the end of the water supply pipe 5, so that the water supply pipe 5 switches from being connected to the bacterial liquid tank 401 to being connected to the clear water tank 402, and then the water spraying component 6 can draw the clear water from the clear water tank 402 and spray it out for cleaning. After the cover plate 102 is closed again, the sealing bar 86 can reset the connecting port 87 and align it with the through hole 84 on the bacterial liquid tank 401 again.
