Description

Technical Field

[0001] This invention relates to the field of multi-stage wastewater treatment technology, specifically to a carbon source treatment device and wastewater treatment method for brewing wastewater. Background Technology

[0002] Brewing wastewater is a major waste product of the brewing process. It encompasses rinsing wastewater, cooling water, and pit water generated during brewing. Rich in polysaccharides, organic acids, ethanol, glycerol, and other organic matter, it is characterized by high concentrations of organic matter, ammonia nitrogen, and suspended solids. Currently, the utilization rate of brewing wastewater is relatively low, and effective utilization methods are lacking. However, direct discharge without utilization or treatment will cause serious environmental harm.

[0003] To this end, Chinese Patent Application Publication No. CN120589822A discloses a wastewater purification device for brewing, which uses two sets of screen plates with different movement modes. When one set of screen plates is working, the other set of screen plates descends below the inclined plate for cleaning. While keeping the screen plates working, the screen plates are cleaned to filter out fruit residue and grain husks in the wastewater, while yeast mud and diatomaceous earth, due to their smaller particle size, pass through the screen for the next stage of treatment.

[0004] While alternating the lifting and lowering of the screen plates can effectively clean them, brewing wastewater contains a large amount of scum. As the screen plates move downwards, the scum can pass through and accumulate at the last stage of the screen, affecting the wastewater treatment effect. Summary of the Invention

[0015] A wastewater treatment method includes the following steps:

[0016] S1. Brewing wastewater is introduced into the treatment tank. The scum is guided to gather in the accumulation area through the protrusions of the scum grid, and the particles below the water surface are intercepted by the screen plate.

[0017] S2. Periodically activate the collection device to collect scum from the accumulation area and maintain the passability of the scum grid.

[0018] The advantages of this invention compared to the prior art are:

[0019] 1. This invention achieves efficient collection of scum from brewing wastewater through a treatment tank, scum grid, and collection device. This prevents scum from spreading indiscriminately, avoids screen blockage, and improves the efficiency of subsequent wastewater treatment. It solves the problem of scum accumulation at the screen in traditional brewing wastewater treatment equipment, which affects wastewater treatment efficiency. During the treatment process, the collection device on the treatment tank is periodically activated to collect the scum from the accumulation area, thus removing it. The support rods of the scum grid ensure its stability in the wastewater, and the wastewater at the bottom can quickly pass through the scum grid and be intercepted by the screen to remove suspended particles. This achieves efficient scum removal and efficient wastewater flow, effectively preventing scum accumulation from affecting screen operation and subsequent wastewater treatment, and improving the overall efficiency of carbon source treatment of brewing wastewater.

[0020] 2. This invention achieves the function of automatically dumping scum after collection. Combined with a conveyor belt, the scum is transported to a designated location, improving the automation level of scum collection and solving the problems of traditional scum collection requiring interruption of wastewater treatment and being inefficient. When the pallet rotates to a vertical position, a limit block prevents it from continuing to rotate, ensuring the pallet remains stably vertical. At this point, the scum on the pallet is accurately dumped onto the conveyor belt, which transports the scum away from the treatment tank. After dumping, the lifting component controls the pallet to move down to the designated position, maintaining its vertical position during the descent until the pallet is completely submerged below the liquid surface, preventing the pallet from pressing scum from the accumulation area into the water and causing scum leakage.

[0021] 3. This invention realizes the functions of driving the pallet to flip and reset, thereby improving the efficiency of pallet state switching. During operation, after the scum gathers in the accumulation area, the lifting component drives the first support to move upward. The pallet remains horizontal and receives the scum under the restriction of the limit block. When it continues to move upward to the conveyor belt, the flipping component controls the pallet to rotate around the first support until it reaches a vertical position. During this process, the force provided by the rotation of the pallet dumps the scum onto the conveyor belt. Attached Figure Description

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1-3 A carbon source treatment device for brewing wastewater includes a treatment tank 1, a screen plate 11 on one side of the treatment tank 1, a scum grid 2 inside the treatment tank 1, a support rod 21 at the bottom of the scum grid 2 connected to the bottom of the treatment tank 1, the scum grid 2 has a protrusion 22 extending toward the screen plate 11, and the protrusion 22 forms an accumulation area for collecting scum; a collection device 3 is provided on the treatment tank 1 for collecting the scum gathered in the accumulation area.

[0036] This invention achieves efficient collection of scum from brewing wastewater through a treatment tank 1, a scum grid 2, and a collection device 3. This avoids the random spread of scum, prevents clogging of the screen plate 11, and improves the efficiency of subsequent wastewater treatment. It solves the problem of scum accumulation at the screen plate 11, which affects wastewater treatment efficiency in traditional brewing wastewater treatment equipment. During operation, brewing wastewater enters the treatment tank 1. As the wastewater flows within the tank, the screen plate 11 performs preliminary treatment, causing scum to float. The scum grid 2 is fixed to the treatment tank 1 by support rods 21. Its protrusions 22 extending towards the screen plate 11 guide the scum, causing it to gradually accumulate towards the protrusions 22, while the rest of the scum grid 2 maintains unobstructed water flow. During the treatment process, the collection device 3 on the treatment tank 1 is periodically activated to collect the scum from the accumulation area, thus removing the scum. The support rod 21 of the scum grid 2 ensures its stability in the wastewater, and the wastewater at the bottom can quickly pass through the scum grid 2 and be intercepted by the screen plate 11 to remove suspended particles in the wastewater. This achieves efficient cleaning of scum and efficient flow of wastewater, effectively preventing scum accumulation from affecting the operation of the screen plate 11 and subsequent wastewater treatment, and improving the overall efficiency of carbon source treatment of brewing wastewater.

[0037] Reference Figures 1-3 The collection device 3 includes a first support 31, a conveyor belt 32, and a lifting assembly 33. A tray 311 is rotatably mounted on the first support 31. The conveyor belt 32 is located on the side of the scum grid 2 away from the protrusion 22. The lifting assembly 33 is mounted on the scum grid 2 and is used to control the first support 31 to move up and down in the vertical direction. The treatment tank 1 is provided with a flipping mechanism 4 for controlling the rotation of the tray 311. The first support 31 is provided with a limiting block for restricting the rotation of the tray 311 between the horizontal and vertical states. When the lifting assembly 33 drives the first support 31 to move up to the conveyor belt 32, the flipping mechanism 4 drives the tray 311 to flip to the vertical state.

[0038] This invention achieves the function of automatically dumping scum after collection, and transports the scum to a designated location with the help of the conveyor belt 32, thereby improving the automation level of scum collection and solving the problems of traditional scum collection requiring interruption of wastewater treatment and low efficiency. During operation, the protrusions 22 of the scum grid 2 gather the scum in the wastewater to the accumulation area. The lifting assembly 33 is activated, driving the first support 31 to rise vertically. The pallet 311 on the first support 31 moves upward to the accumulation area. At this time, the pallet 311 remains horizontal under the constraint of the limiting block to receive the scum. After the pallet 311 has borne the scum, the lifting assembly 33 continues to drive the first support 31 to move upward to the conveyor belt 32. The tilting mechanism 4 on the treatment tank 1 is activated, controlling the pallet 311 to rotate from a horizontal to a vertical position. When the pallet 311 rotates to a vertical position, the limiting block prevents it from rotating further, ensuring that the pallet 311 remains stably in a vertical position. At this time, the scum on the pallet 311 is accurately poured onto the conveyor belt 32, which transports the scum away from the treatment tank 1. After pouring, the lifting assembly 33 controls the pallet 311 to move down to a designated position, maintaining the pallet 311 in a vertical position during the descent until it is completely submerged below the liquid surface, preventing the pallet 311 from pressing the scum in the accumulation area into the water and causing scum leakage. Once the pallet 311 has moved down below the liquid surface, the tilting mechanism 4 drives the pallet 311 to rotate in the opposite direction, and the limiting block again restricts the pallet 311 to return to a horizontal position, ready for the next scum collection. The limiting block allows the rotation angle of the pallet 311 to be controllable, avoiding component damage or pouring deviation caused by excessive rotation. Furthermore, the cooperation between the lifting assembly 33 and the tilting mechanism 4 achieves fully automated scum collection.

[0039] Reference Figures 2-4 The flipping mechanism 4 includes a flipping component 41 and a reset component 42. The flipping component 41 and the reset component 42 are respectively disposed on the upper and lower sides of the scum grid 2. The flipping component 41 is used to rotate the horizontal support plate 311 to the vertical position, and the reset component 42 is used to rotate the vertical support plate 311 to the horizontal position.

[0040] This invention realizes the flipping and resetting functions of the drive plate 311, thereby improving the efficiency of the plate 311's state switching. During operation, after the scum gathers in the accumulation area, the lifting component 33 drives the first support 31 upwards. The plate 311, restrained by the limiting block, remains horizontal to receive the scum. As it continues to move upwards to the conveyor belt 32, the flipping component 41 controls the plate 31 to rotate around the first support 31 until it reaches a vertical position. During this process, the force provided by the rotation of the plate 311 dumps the scum onto the conveyor belt 32. After dumping, the lifting component 33 drives the first support 31 downwards. When the plate 311 moves to the lower side of the scum grid 2, the resetting component 42 controls the plate 311 to rotate in the opposite direction, and the limiting block resets the plate 311 to a horizontal position.

[0041] Reference Figures 3-5 The overturning assembly 41 includes an extension plate 411 and a side plate 412. The extension plate 411 is connected to the support plate 311. The first support 31 is provided with a receiving groove 312 for accommodating the extension plate 411. The side plate 412 is located on the side of the conveyor belt 32 near the scum grid 2. During the upward movement of the first support 31 and the support plate 311, the extension plate 411 on the support plate 311 rotates under the pressure after contacting the side plate 412.

[0042] This invention realizes the mechanically triggered flipping function of the pallet 311, achieving the effect of flipping without additional power and simplifying the structure. It can automatically control the flipping of the pallet 311 when it moves to the conveyor belt 32. During operation, after the scum gathers in the accumulation area, the lifting component 33 drives the first support 31 and the pallet 311 to move vertically upward. The pallet 311 remains horizontal to receive the scum. As the first support 31 continues to move upward to the conveyor belt 32, the extension plate 411 on the pallet 311 contacts the side plate 412 on the side of the conveyor belt 32. During the continuous upward movement, the side plate 412 exerts a squeezing effect on the extension plate 411. The extension plate 411 drives the pallet 311 to rotate around the first support 31 until the limiting block on the first support 31 restricts the pallet 311 to stop in a vertical position. The scum on the pallet 311 is poured onto the conveyor belt 32. At this time, the extension plate 411 connected to the pallet 311 is located in the receiving groove 312 of the first support 31, so as to avoid the extension plate 411 affecting the rotation of the pallet 311.

[0043] Reference Figures 5-8 The first bracket 31 is provided with a rotating shaft 313, a support 314 and a tension spring 315; the rotating shaft 313 is fixedly connected to the support plate 311, and a connecting block 3131 is fixedly sleeved on the rotating shaft 313; the support 314 is provided on the first bracket 31, and an extension rod 3141 is provided on the support 314; the rotating shaft 313 is rotatably connected to the support 314; the two ends of the tension spring 315 are respectively hinged to the extension rod 3141 and the connecting block 3131.

[0044] This invention achieves the function of stabilizing the horizontal or vertical state of the pallet 311, thereby improving the stability of the pallet 311 during lifting and lowering. During operation, when the pallet 311 is in a horizontal state, the tension spring 315 is in an extended state. Through the cooperation of the extension rod 3141 and the connecting block 3131, the elastic force of the tension spring 315, in conjunction with the limiting block, keeps the pallet 311 in a horizontal state, ensuring that the pallet 311 does not shake when receiving scum from the accumulation area. When the lifting assembly 33 moves the first support 31 to the conveyor belt 32, the flipping mechanism 4 drives the tray 311 to rotate. The tray 311 drives the rotating shaft 313 to rotate around the support 314. The connecting block 3131 on the rotating shaft 313 rotates synchronously and pulls the tension spring 315 to stretch and deform it. When the extension direction of the extension rod 3141 is parallel to the stretching direction of the tension spring 315, the tension spring 315 has the maximum elastic force. Then the tray 311 continues to rotate, and the component force of the tension spring 315 changes to drive the tray 311 to rotate in the horizontal direction. After the tray 311 rotates to the horizontal state, the state of the tray 311 is maintained.

[0045] Reference Figure 2 and Figure 9 The lifting assembly 33 includes a guide rail 331, a vertical rod 332, and a connecting rod 333. The guide rail 331 is mounted on the scum grid 2, and a slider 3311 is slidably mounted on the guide rail 331. The vertical rod 332 is connected to the first support 31, and the two ends of the connecting rod 333 are hinged to the vertical rod 332 and the slider 3311, respectively. The treatment tank 1 is provided with a linear drive assembly 34 for driving the slider 3311 to move along the guide rail 331.

[0046] This invention achieves the function of driving the first support 31 to move vertically upwards and downwards through guide rail 331, upright rod 332, connecting rod 333, and linear drive assembly 34. The first support 31 is slidably engaged with the scum grid 2, allowing the first support 31 to move only in the vertical direction. The linear drive assembly 34 includes a rotary driver and a screw. The rotary driver is disposed on the outer wall of the treatment tank 1, and the screw is rotatably disposed on the guide rail 331 and threadedly connected to the slider 3311. The rotary driver is used to drive the screw to rotate. There are at least two guide rails 331 and screws, with two screws rotatably disposed on two guide rails 331 respectively. The two guide rails 331 are respectively disposed on both sides of the protrusion 22, and the two screws are connected by a drive shaft and a drive belt. The helical directions of the two screws are opposite. When the rotary driver drives one screw to rotate, that screw drives the other screw to rotate synchronously through the drive shaft, thereby controlling the two sliders 3311 to move simultaneously toward the protrusion 22. The slider 3311 pushes the upright 332 upward via the connecting rod 333, and the upright 332 drives the first support 31 and the support plate 311 upward. After the tilting is completed, the linear drive assembly 34 drives the two sliders 3311 to move away from the protrusion 22, and the connecting rod 333 pulls the upright 332 downward.

[0047] Reference Figure 3 , Figure 4 , Figure 10 and Figure 11 The reset assembly 42 includes a second bracket 421 and a movable frame 422; the second bracket 421 is connected to the support rod 21; the movable frame 422 is slidably mounted on the second bracket 421, and the movable frame 422 is provided with a push block 4221 for pushing the extension plate 411; the second bracket 421 is provided with a retraction assembly 43 for controlling the second bracket 421 to move in the horizontal direction.

[0048] The present invention achieves the function of driving the pallet 311 to rotate horizontally through the second bracket 421, the movable frame 422, and the retraction assembly 43. In the working state, when the pallet 311 moves down to the second bracket 421, the push block 4221 on the movable frame 422 contacts the extension plate 411 and squeezes the extension plate 411. Then, the retraction assembly 43 controls the movable frame 422 to move away from the protrusion 22, thereby pushing the pallet 311 to continue rotating to the horizontal state and controlling the pallet 311 to return to its original position.

[0049] Reference Figure 10 and Figure 11 The retraction assembly 43 includes a third bracket 431, a locking block 432, and a third elastic element 433. The third bracket 431 is mounted on the second bracket 421 and is slidably engaged with the second bracket 421. The third bracket 431 is provided with a first elastic element 4311, and both ends of the first elastic element 4311 are connected to the third bracket 431 and the movable frame 422, respectively. The locking block 432 is slidably mounted on the second bracket 421 and is provided with a second elastic element 4321, and both ends of the second elastic element 4321 are connected to the locking block 432 and the second bracket 421, respectively. Both ends of the third elastic element 433 are connected to the third bracket 431 and the second bracket 421, respectively. The second bracket 421 is provided with a linear actuator 423 for pushing the movable frame 422 to move.

[0050] The present invention achieves the function of controlling the retraction of the movable frame 422 through the third bracket 431, the locking block 432 and the third elastic element 433. When the pallet 311 moves down to the second bracket 421, the push block 4221 on the movable frame 422 contacts the extension plate 411 and squeezes the extension plate 411. At the same time, the push block 4221 is pressed, the first elastic element 4311 is compressed and contracts, the movable frame 422 moves down, and then the slot 4222 on the movable frame 422 separates from the block 432 on the second bracket 421, releasing the movement restriction of the block 432 on the third bracket 431. Under the elastic force of the third elastic element 433, the third bracket 431 moves away from the scum grid 2, further pushing the extension plate 411 on the pallet 311, so that the pallet 311 continues to rotate to a horizontal state, controlling the pallet 311 to reset. After the reset is completed, the third bracket 431 is pushed to reset again by the linear driver 423. When the block 432 is aligned with the slot 4222, it is inserted and engaged with the slot 4222 under the elastic force of the second elastic element 4321.

[0051] Reference Figure 10 and Figure 11 The third bracket 431 is provided with a protective shell 434 for protecting the third elastic element 433, and the protective shell 434 is slidably engaged with the second bracket 421.

[0052] This invention achieves the function of protecting the third elastic element 433 through the protective shell 434. To ensure that the support plate 311 can smoothly lift scum from the water surface after returning to a horizontal state, a rotational reset action needs to be performed underwater. Therefore, the reset assembly 42 needs to be installed underwater. To prevent the third elastic element 433 from being affected by debris in the water, the protective shell 434 is provided to isolate the third elastic element 433, thereby extending the service life of the parts and improving the stability of equipment operation.
