Description

Technical Field

[0001] This utility model belongs to the field of brewing wastewater treatment technology, specifically relating to an automatic diversion device for leachate from the bottom of a sauce-flavored liquor cellar. Background Technology

[0002] Cellar bottom water (also known as yellow water) is a byproduct produced during the solid-state fermentation of Maotai-flavor liquor. Maotai-flavor liquor is made from crushed sorghum, using daqu (large koji), bran koji, and saccharifying enzymes (or dry yeast) in a certain proportion as saccharifying and fermenting agents in fermentation pits. The leachate produced during the fermentation process of Maotai-flavor liquor in the fermentation pits is the cellar bottom water. The composition of cellar bottom water is complex. In addition to small molecules of alcohols, aldehydes, acids, and esters, it also contains abundant sugars, proteins, and a large number of long-term domesticated microorganisms. In addition to a high ethanol content (generally around 3%), conventional cellar bottom water also contains ethyl acetate, acetic acid, propanol, propionic acid, and some higher alcohols and higher acids, which are irritating substances, resulting in a strong irritating and unpleasant odor. During the brewing process, it is often necessary to discharge the leachate from the dripping process. If the leachate is discharged directly without treatment, it will cause great environmental pollution. Utility Model Content

[0003] This invention provides an automatic diversion device for the leachate from the bottom of a liquor cellar, which can solve the problem of directly discharging the leachate without treatment.

[0004] To achieve the above objectives, this solution provides an automatic diversion device for leachate from the bottom of a Maotai-flavor liquor cellar, comprising a treatment tank and a water pump. The treatment tank is connected to a diversion pipe for recovering leachate. A fixed plate is fixedly installed in the treatment tank, and a motor is fixedly installed on the fixed plate. A rotating plate is rotatably installed in the treatment tank, and a rotating barrel is fixedly installed on the rotating plate. The output shaft of the motor is fixedly connected to the rotating plate. Filter holes are provided on the rotating barrel, the rotating plate, and the fixed plate. The water pump is connected to the diversion pipe.

[0005] The principle of this solution is as follows: First, the lees are placed in a rotating tank. Then, the motor is started so that the output shaft of the motor drives the rotating tank to rotate. This causes the leachate in the lees to be thrown out of the lees due to centrifugal force. The leachate then falls from the filter holes on the rotating plate and the fixed plate to the bottom of the treatment tank. Then, the water pump is turned on, and the leachate enters the water pump through the guide pipe for subsequent treatment.

[0006] The beneficial effects of this solution are: by setting up a recycling tank, the leachate in the distiller's grains is separated and recycled through a diversion pipe, thus avoiding direct discharge that would pollute the environment.

[0007] Furthermore, it also includes a recycling frame that matches the rotating drum, the recycling frame having filter holes and lifting lugs.

[0008] Beneficial effects: The recycling bin is placed inside the rotating drum, and then the lees are put into the recycling bin. After centrifugal separation, the recycling bin is removed by the lifting lugs, and the lees can be recycled.

[0009] Furthermore, both the fixed plate and the rotating plate are inclined downwards along the circumference from the center, and the bottom of the treatment tank is inclined, with the lowest point of the bottom of the treatment tank connected to the guide pipe.

[0010] Beneficial effect: The inclined setting facilitates the absorption of leachate by the guide pipe.

[0011] Furthermore, the treatment tank is also equipped with a water inlet pipe, which is connected to a cleaning nozzle.

[0012] Beneficial effects: After the leachate is separated and the lees are discharged, the inside of the treatment tank is cleaned through the cleaning nozzle.

[0013] Furthermore, it also includes a preheating tank, which is equipped with a heating pipe, and the preheating tank is connected to the water pump through a pipeline.

[0014] Beneficial effects: The leachate is pumped into the preheating tank by a water suction pump and heated by a heating tube. The heating control temperature is set at 85-95℃, and the temperature is fed back by a thermometer.

[0015] Furthermore, it also includes a separation tower, which is equipped with Hastelloy mesh ring packing and is connected to a preheater via a pipeline.

[0016] Beneficial effects: After preheating, the permeate enters the separation tower, where it comes into uniform contact with the Hastelloy mesh packing and flows downwards. The separation tower distills the permeate to extract alcohols and organic compounds, reducing subsequent wastewater treatment costs. At the same time, the extracted alcohols and organic compounds can be used as raw materials to prepare high-value-added products such as olefins, realizing a resource utilization approach.

[0017] Furthermore, it also includes a controller that is electrically connected to the water pump and motor, the preheating tank and the separation tower.

[0018] Beneficial effects: When the lees enter the recycling box, the controller controls the motor to rotate, which in turn causes the permeate to undergo centrifugal separation. After centrifugal separation is completed, the controller controls the water pump to draw in the permeate and introduce it into the preheating tank for preheating. After preheating, the controller controls the permeate to enter the separation tower for extraction of alcohol organic matter.

[0019] Furthermore, it also includes a waterproof device, with the motor located within the waterproof device.

[0020] Beneficial effect: Prevents the permeate from washing over the motor and causing damage. Attached Figure Description

[0023] As attached Figure 1-2 As shown, An automatic drainage device for leachate from the bottom of a liquor fermentation cellar includes a treatment tank 1 and a suction pump 2. A drainage pipe 3 for recovering leachate is connected inside the treatment tank 1. A fixed plate 4 is fixedly installed inside the treatment tank 1, and a motor 5 is fixedly installed on the fixed plate 4. A rotating plate 6 is rotatably installed inside the treatment tank 1. Both the fixed plate 4 and the rotating plate are inclined downwards along the circumference from the center. The bottom of the treatment tank 1 is also inclined, and the lowest point of the bottom of the treatment tank 1 is connected to the drainage pipe 3. The inclined arrangement facilitates the absorption of leachate by the drainage pipe 3.

[0024] A rotating drum 7 is fixedly mounted on the rotating plate 6. The output shaft of the motor 5 is fixedly connected to the rotating plate 6. Filter holes are provided on the rotating drum 7, the rotating plate, and the fixed plate 4. The water pump 2 is connected to the guide pipe 3. A waterproof device 13 is also included, and the motor 5 is located inside the waterproof device 13. This prevents the permeable liquid from washing over the motor 5 and causing damage.

[0025] It also includes a recycling frame 8, which matches the rotating drum 7. The recycling frame 8 is equipped with filter holes and lifting lugs. The recycling frame 8 is placed inside the rotating drum 7, and then the lees are put into the recycling frame 8. After centrifugal separation, the recycling frame 8 is removed by the lifting lugs, thus enabling the recycling of the lees.

[0026] The treatment tank 1 is also equipped with a water inlet pipe 9, which is connected to a cleaning nozzle. After the leachate is separated and the lees are discharged, the inside of the treatment tank 1 is cleaned through the cleaning nozzle. The guide pipe 3 is detachably connected to the suction pump 2. At this time, the suction pump 2 can be removed, and the guide pipe 3 can be connected to the wastewater discharge pump to discharge the cleaning water. Then, the guide pipe 3 can be connected back to the suction pump 2.

[0027] The system also includes a preheating tank 11 and a separation tower 12. The preheating tank 11 is equipped with heating pipes and is connected to the suction pump 2 via a pipeline. The separation tower 12 is equipped with Hastelloy mesh ring packing and is connected to the preheater via a pipeline. The leachate is pumped into the preheating tank 11 by the suction pump 2 and heated by the heating pipes. The heating control temperature is set at 85–95°C, and temperature feedback is obtained through a thermometer. After preheating, the leachate enters the separation tower 12, where it flows downwards in uniform contact with the Hastelloy mesh ring packing. The separation tower 12 distills and extracts alcohols from the leachate, reducing subsequent wastewater treatment costs. Simultaneously, the extracted alcohols can be used as raw materials to prepare high-value-added products such as olefins, realizing a resource utilization pathway.

[0028] It also includes a controller, which is electrically connected to the water pump 2, the motor 5, the preheating tank 11, and the separation tower 12. When the lees enter the recovery frame 8, the controller controls the motor 5 to rotate, thereby causing the permeate to undergo centrifugal separation. After centrifugal separation is completed, the controller controls the water pump 2 to draw in the permeate and introduce it into the preheating tank 11 for preheating. After preheating is completed, the controller controls the permeate to enter the separation tower 12 for extraction of alcohol organic matter.

[0029] Specific operations: The recycling box 8 is placed inside the rotating drum 7, and then the lees are put into the recycling box 8. The controller then starts the motor 5, causing the output shaft of the motor 5 to drive the rotating drum 7 to rotate. This causes the leachate in the lees to be thrown out of the lees due to centrifugal force, and then falls from the filter holes on the rotating plate and the fixed plate 4 to the bottom of the treatment tank 1. Then the water pump 2 is turned on, and the leachate enters the water pump 2 through the guide pipe 3. The leachate is pumped into the preheating tank 11 by the water pump 2 and heated by the heating pipe. The heating control temperature is set to 85-95℃, and the temperature is fed back by a thermometer.

[0030] After preheating, the permeate enters the separation tower 12. The permeate comes into uniform contact with the Hastelloy mesh packing and flows downwards. The separation tower 12 distills the permeate to extract alcohols and organic compounds, reducing subsequent wastewater treatment costs. Simultaneously, the extracted alcohols and organic compounds can be used as raw materials to prepare high-value-added products such as olefins, realizing a resource utilization pathway. After the permeate separation is complete and the lees are discharged, the inside of the treatment tank 1 is cleaned using cleaning nozzles.
