Description

Technical Field

[0001] This application relates to the field of baijiu wastewater purification technology, and in particular to a baijiu production wastewater degradation and recycling device. Background Technology

[0002] In the solid-state fermentation and distillation production of baijiu, the yellow water formed after the fermentation of the mash in the fermentation pit enters the distillation process along with the mash. The discarded mash after distillation contains a large amount of high-concentration organic wastewater, which is carried by incompletely transformed grain residues such as sorghum and rice husks, fermentation by-products, and mud residues generated from cleaning the bottom of the fermentation pit. These waste residues have high water retention capacity due to their rich content of rice husk fiber, grain residue fragments, and colloidal organic matter. The acidic wastewater containing residual alcohol, organic acids, soluble sugars, and amino acids needs to be purified before it can be discharged in compliance with standards. Traditional treatment methods for solid waste residue rich in rice husk fiber and grain residue generated after distillation generally involve simple grid interception or large-aperture screen filtration followed by direct transport to landfill or open-air composting. This extensive disposal method not only causes the high concentration of organic wastewater carried in the waste residue to be lost disorderly with leachate, resulting in a huge waste of water resources, but also, due to the high water retention capacity of the waste residue, the composting process is prone to generating foul odors and secondary pollution, making it impossible to effectively extract and reuse the liquid resources in the waste residue, thus restricting the green circular economy benefits of liquor production. Summary of the Invention

[0007] Preferably, the bottom of the circular tube is provided with at least four connecting shafts, which are arranged in a circular array at the bottom of the circular tube, and a toothed ring is also provided on the outer side of the circular tube; A rack engages with the outer side of the gear ring, and the two ends of the rack are respectively fixed to two feed hoppers.

[0008] Preferably, a turntable is fixedly installed inside the upper part of the circular tube. The turntable is coaxial with the circular tube and is shaped like a frustum. A transmission rod passes through the middle of the turntable. The transmission rod includes a vertical part and a horizontal part. The horizontal part of the transmission rod is located below the connecting shaft.

[0009] Preferably, a sleeve is connected to the side wall of the support, a piston is embedded in one end of the sleeve, a one-way valve is provided on the piston, and the end of the piston away from the sleeve is connected to the feed hopper; A three-way connector is provided between the two sleeves, and a one-way valve is provided between the sleeve and the three-way connector.

[0010] Preferably, the transmission rod has an internal cavity, one of the joints of the three-way connector is connected to the internal cavity of the transmission rod, and the horizontal part of the transmission rod has a spray hole that is connected to the internal cavity.

[0011] Preferably, at least four flow-guiding protrusions are provided, which are evenly distributed along the upper surface of the disk, and the flow-guiding protrusions have a frustum-shaped structure.

[0012] Preferably, a stirring rod is provided at the lower part of the connecting shaft, the stirring rod and the connecting shaft are at an angle of 90°, and the stirring rod is symmetrically arranged on both sides of the connecting shaft.

[0013] Preferably, the outer wall of the tank is provided with a slide rail, the feed hopper is slidably connected to the slide rail, the bottom of the feed hopper is provided with a discharge port, and the bottom discharge port of the feed hopper is provided with a slide valve. Compared with the prior art, this application has at least the following advantages:

[0014] In the above solution, a mechanical pressure filtration and dewatering mechanism consisting of a feeding hopper, hydraulic cylinder, and filter plate solves the core problem of the traditional extensive disposal mode. This mechanism uses a hydraulic cylinder to drive the feeding hopper to actively and forcefully squeeze the waste residue laterally, efficiently destroying its fiber water-holding structure, forcibly separating the sealed high-concentration organic wastewater and exporting it through the filter plate, thus achieving deep dewatering. This not only eliminates the disorderly loss of leachate and water pollution from the source, but also effectively curbs the odor and secondary pollution generated by subsequent composting due to the significantly reduced water content of the dewatered waste residue. At the same time, the centrally collected wastewater creates conditions for subsequent resource recycling processes, improving resource utilization.

[0015] In the above scheme, the diversion component set on the connecting shaft can actively intercept and impact the waste liquid flow thrown from the side outlet of the feed hopper. After impacting the guide protrusion and the disc, the water flow is forcibly dispersed and broken into smaller droplets and water splashes, which increases the specific surface area and turbulence of the waste liquid, thereby significantly accelerating the mixing and reaction speed of the subsequently added reagents with the waste liquid and improving the treatment efficiency.

[0016] In the above scheme, by setting up a linkage design of feeding hopper, rack, gear ring and circular tube, the horizontal reciprocating linear motion of feeding hopper is automatically converted into the revolution motion of diversion component and connecting shaft. This motion conversion mechanism makes the disc, guide protrusion and stirring rod make compound motion in the tank, constantly changing position and angle, eliminating the stirring dead zone, realizing full-area dynamic stirring of liquid in the tank from the upper water flow breaking to the bottom sludge stirring, and the mixing effect surpasses the traditional device of static or single-direction stirring.

[0017] In the above scheme, by setting up a combination of a circular pipe, a transmission rod, a flow assembly, and a sleeve, piston, and transmission rod, compressed air is generated by the piston driven by the feed hopper and injected into the rotating transmission rod to form microbubble aeration. This not only further enhances liquid mixing, but the generated bubbles also help to adhere flocs, realizing integrated solid-liquid separation of mixing reaction and dissolved air flotation, and improving sludge removal rate.

[0018] In the above scheme, the intermittent and quantitative automatic addition of the agent is achieved by using the synchronous control of the opening and closing of the baffle in the moving feed hopper. The added agent first falls on the rotating frustum-shaped turntable and is initially dispersed under the action of centrifugal force. Then it is sprayed by the airflow from the pneumatic system to achieve secondary dispersion. This multi-stage dispersion mechanism effectively prevents the agent from clumping or the local concentration from being too high, ensuring that the agent diffuses rapidly and evenly in the waste liquid, improving the agent utilization rate, and avoiding incomplete reaction.

[0022] The following is a detailed description of a wastewater degradation and recycling device for liquor production provided in this application, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this application.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4The present application provides an embodiment of a wastewater degradation and recycling device for liquor production, which includes a tank 1 and a storage box 101 on top. The storage box 101 has a discharge port at the bottom center. The tank 1 also includes a dehydration component, which includes a feeding hopper 2, a hydraulic cylinder 201 and a connecting rod 202. The feeding hopper 2 is slidably disposed on the side of the tank 1. The hydraulic cylinder 201 is installed between the feeding hopper 2 and the tank 1. The connecting rod 202 is installed on the side between the two feeding hoppers 2. A baffle 2011 is also provided between the two feed hoppers 2. Both sides of the baffle 2011 are provided with hollow holes, and the upper surface of the baffle 2011 is attached to the bottom surface of the storage box 101. A filter plate 102 is fixedly installed on the side wall of the tank body 1. The filter plate 102 is embedded in the inside of the feed hopper 2. The feed hopper 2 has an outlet at one end that extends through to the inside of the tank body 1. The top of the feeding hopper 2 has an opening for feeding. In actual production, when processing the solid waste residue rich in rice husk fiber and grain residue produced after the distillation of liquor, a set of hydraulic cylinders 201 on the side of the tank 1 drives the feeding hopper 2 to move horizontally. For example, when the hydraulic cylinder 201 on the left side of the tank 1 extends, it drives the feeding hopper 2 on the left side to move away from the tank 1, so that the opening of the feeding hopper 2 on the left side is fully exposed to the outside, making it easy to fill the waste residue inside. At this time, the feeding hopper 2 on the right side moves into the tank 1. The right side wall of the feeding hopper 2 on the right side keeps approaching the filter plate 102. Using the squeezing force generated by the hydraulic cylinder 201, the waste residue inside the feeding hopper 2 is squeezed and its internal water-holding structure is destroyed. The pressure destroys its fiber network structure and releases the internal sealed wastewater, allowing the waste liquid to pass through the filter plate 102 and flow into the tank 1, thereby reducing the water content in the waste residue and making the subsequent treatment of the waste residue more convenient. By pre-filling the storage tank 101 with chemicals, such as flocculants or chemicals to neutralize the acidity and alkalinity of the waste liquid, as the left feed hopper 2 moves horizontally to the left, the left feed hopper 2 drives the baffle 2011 to move horizontally. The moving path of the hollow hole set on the baffle 2011 is located directly below the discharge port of the storage tank 101. When the hollow hole on the baffle 2011 coincides with the discharge port at the bottom of the storage tank 101, the chemicals in the storage tank 101 can pass through the hollow hole of the baffle 2011 under the action of gravity and enter the tank 1, thereby achieving the effect of automatically releasing the chemicals. As the left feed hopper 2 moves further, the discharge port at the bottom of the storage box 101 is closed again. At this time, the waste residue in the right feed hopper 2 is in a pressurized state, and the liquid in the waste residue continues to seep out. At this time, the whole device is in a static state, which allows the agent and the waste liquid to react fully. At this time, the waste residue to be treated can also be continuously filled into the fully open left feed hopper 2, waiting for the next dehydration cycle, thus achieving good working efficiency. After sedimentation, the upper clear liquid can be discharged through the upper liquid outlet pipe set on the side of tank 1, and the flocculent material generated after flocculation and sedimentation can be discharged through the sewage pipe at the bottom of the side of tank 1, so as to achieve the recycling of water resources in waste liquid.

[0024] In this embodiment, as Figures 2-6 As shown, the diameter of the perforated hole in the baffle 2011 is twice the diameter of the discharge port at the bottom of the storage box 101; This design ensures that the agent discharged from the bottom of the storage tank 101 can pass through the perforated holes on the baffle 2011 better, effectively preventing blockage and meeting the requirement of sufficient agent dispersion, which is conducive to the rapid and uniform diffusion of the agent into the waste liquid.

[0025] A support 3 is connected to the upper part of the inside of the tank 1. A circular tube 301 is rotatably connected to the middle of the support 3. A feed inlet is provided at the top of the circular tube 301. The feed inlet of the circular tube 301 and the feed inlet at the bottom of the storage box 101 are set on the same vertical line. A connecting shaft 302 is installed at the bottom of the circular tube 301. A diversion component is fixedly connected to the middle of the connecting shaft 302. The diversion assembly includes a disc 3021 and a guide protrusion 3022. The disc 3021 is fixedly installed on the side wall of the connecting shaft 302. The installation height of the disc 3021 is lower than the water outlet on the side of the feed hopper 2. The guide protrusion 3022 is located on the top of the disc 3021. The waste liquid inside the feed hopper 2 is discharged from the outlet on one side under the action of gravity. The trajectory of the waste liquid after leaving the feed hopper 2 is a parabolic trajectory. This trajectory intersects with the disc 3021 and the guide protrusion 3022, so that the waste liquid can impact the disc 3021 and the guide protrusion 3022. The waste liquid is blocked by the water flow on the water-facing surface of the guide protrusion 3022 and generates reflected turbulence. It also guides the water flow to disperse radially outward of the guide protrusion 3022, and the continuous water flow is broken and dispersed again after passing through the disc 3021. This process is beneficial to agitate the waste liquid inside the tank 1, form local turbulence, accelerate the mixing and reaction process of waste liquid and reagent, and improve the treatment efficiency. Furthermore, since the feed hopper 2 can be in a horizontal displacement state under the drive of the hydraulic cylinder 201, the position of the outlet on the side of the feed hopper 2 relative to the disc 3021 and the guide protrusion 3022 is constantly changing. This causes the impact angle of the waste liquid flow relative to the disc 3021 and the guide protrusion 3022 to continuously change, thereby dynamically adjusting the dispersion state and range of the water flow to achieve a better mixing effect.

[0026] At least four connecting shafts 302 are provided at the bottom of the circular tube 301. The four connecting shafts 302 are arranged in a ring at the bottom of the circular tube 301. A toothed ring 303 is also provided on the outer side of the circular tube 301. A rack 304 meshes with the outer side of the gear ring 303, and the two ends of the rack 304 are respectively fixed to the two feed hoppers 2; Through this structure, the multiple connecting shafts 302 and the disks 3021 on the circular tube 301 can work together to disperse the falling waste liquid from different directions. The key is that during the horizontal reciprocating motion of the feed hopper 2, the feed hopper 2 simultaneously drives the rack 304 to make horizontal linear motion. The rack 304 then drives the meshing gear ring 303 to rotate, which in turn drives the circular tube 301 to rotate. This linkage design realizes that the four connecting shafts 302 and the disks 3021 on them and the guide protrusions 3022 revolve around the axis of the circular tube 301, continuously changing their relative positions with the falling waste liquid. Combined with the horizontal movement of the feed hopper 2 itself, this compound motion can more effectively agitate the waste liquid inside the tank 1 throughout the entire tank, greatly accelerating the mass transfer and reaction process between the waste liquid and the reagent, thereby significantly improving the working efficiency of the entire device.

[0027] A turntable 305 is fixedly installed inside the upper part of the round tube 301. The turntable 305 is coaxial with the round tube 301 and is shaped like a frustum. A transmission rod 306 passes through the middle of the turntable 305. The transmission rod 306 includes a vertical part and a horizontal part. The horizontal part of the transmission rod 306 is located below the connecting shaft 302. A circular hole is provided at the top of the circular tube. The diameter of the circular hole is the same as the diameter of the hollow hole provided on the baffle 2011, which facilitates the release of the agent in the storage box 101 into the tank 1. During the falling process of the agent, the agent first contacts the turntable 305 and is dispersed radially outward by the guiding action of the inclined surface of the turntable 305. As the circular tube 301 rotates, it drives the turntable 305 to rotate synchronously. Under the action of friction, centrifugal force and inclined surface guidance, the agent is evenly thrown outward when it contacts the turntable 305, and the agent is further dispersed, thereby preventing the agent from accumulating into clumps directly below the circular tube 301. At the same time, due to the action of the disc 3021 and the guide protrusion 3022, the waste liquid flow is also dispersed in the cavity of the tank 1 to form turbulence. The dispersed reagent and the fully diffused water flow can fully and quickly come into contact in this dynamic environment, which greatly promotes the chemical process such as flocculation reaction and improves the treatment efficiency. In addition, the transmission rod 306 fixed on the turntable 305 will rotate together, and its horizontal part can penetrate into the liquid to mechanically stir the liquid in the lower layer of the tank 1, further promoting the uniform distribution of the agent in the wastewater and fully reacting with the suspended solids in the water.

[0028] A sleeve 4 is connected to the side wall of the support 3. A piston 401 is embedded in one end of the sleeve 4. A one-way valve 402 is provided on the piston 401. The end of the piston 401 away from the sleeve 4 is connected to the feed hopper 2. A three-way connector 403 is provided between the two sleeves 4, and a one-way valve is provided between the sleeve 4 and the three-way connector 403; When the feed hopper 2 moves horizontally, the piston 401 on one side is driven by the feed hopper 2 and extends into the sleeve 4. The air inside the sleeve 4 is squeezed into the three-way connector 403 and ejected. The three-way connector 403 is located above the turntable 305. The airflow ejected from the three-way connector 403 is used to further spray the powder on the turntable 305, so that the powder is diffused into the air and then falls evenly into the water inside the tank 1. This can avoid the problem of incomplete reaction caused by excessively high local concentration of the agent or uneven sedimentation, and is conducive to fully reacting with the waste liquid.

[0029] The transmission rod 306 has an internal cavity, one of the joints of the three-way connector 403 is connected to the internal cavity of the transmission rod 306, and the horizontal part of the transmission rod 306 has spray holes that are connected to the internal cavity. The transmission rod 306 is connected to the three-way connector 403, so that the air inside the sleeve 4 can be forced into the transmission rod 306. The rotating transmission rod 306 not only uses air jet to agitate the water flow, but also forms a full-coverage turbulent shear force in the tank 1 through its own mechanical rotation, breaking the stirring dead zone that exists in traditional static aeration, so that the flocculant can have all-round, high-frequency collision contact with colloidal particles and fine suspended matter in the wastewater, promoting the rapid growth of flocs in the dynamic environment and making the structure dense. Furthermore, as the transmission rod 306 rotates, the bubble group is forcibly cut and evenly dispersed into the entire tank 1, thereby greatly increasing the probability of the bubbles combining with pollutants. The buoyancy of the bubbles is used to continuously lift the combined flocs to the liquid surface to form a stable scum layer, realizing integrated and efficient solid-liquid separation of mixing reaction and dissolved air flotation. At least four flow guide protrusions 3022 are provided. The flow guide protrusions 3022 are evenly distributed along the upper surface of the disk 3021 and have a frustum-shaped structure. Four or more frustum-shaped guide protrusions 3022 can form a highly efficient dispersion array, which works synergistically to cut and splash the water flowing out of the outlet of the feed hopper 2 into finer droplets and water splashes, greatly increasing the specific surface area of ​​the water flow, thereby significantly accelerating the mixing and diffusion speed of the reagent and waste liquid, and improving the overall treatment effect.

[0030] A stirring rod 3023 is provided at the lower part of the connecting shaft 302. The stirring rod 3023 and the connecting shaft 302 have an angle of 90°. The stirring rod 3023 is symmetrically arranged on both sides of the connecting shaft 302. During the rotation of the circular tube 301, the connecting shaft 302 revolves around its axis. The connecting shaft 302 and the stirring rod 3023 below it act like a rotating paddle system, which strongly stirs the liquid in the lower part of the tank 1, especially in the area near the bottom, to prevent sludge deposition and ensure that the reagent is evenly diffused throughout the entire height of the tank, thus accelerating the reaction process.

[0031] The outer wall of the tank body 1 is provided with a slide rail 103, the feed hopper 2 is slidably connected to the slide rail 103, the bottom of the feed hopper 2 is provided with a discharge port, and the bottom discharge port of the feed hopper 2 is provided with a slide valve. The slide rail 103 installed on the tank body 1 ensures the stability and smoothness of the sliding of the feed hopper 2 and achieves precise positioning of the feed hopper 2. A slide valve is installed on the feed hopper 2 to discharge the dehydrated waste material on the feed hopper 2.
