Description

Technical Field

[0001] The present invention relates to the technical field of multi-stage wastewater treatment, in particular to a wastewater purification device for brewing. Background Art

[0002] The wastewater generated in the winemaking process mainly includes the following categories. Its sources and components vary depending on the brewing process, such as beer, liquor and wine. The wastewater contains suspended matter, which mainly includes grain husks, pomace, yeast mud and diatomaceous earth. Diatomaceous earth is a recyclable resource and can be recycled when treating winemaking wastewater.

[0003] An existing patent application, CN116969533A, is titled "A Process for Treating Brewery Wastewater," comprising a treatment tank, the upper right portion of which is recessed downward to form a discharge trough. A filter plate is mounted in the middle of the tank's inner cavity, and an air separation structure is disposed below the filter plate. The air inlet of the air separation structure extends to the left side of the treatment tank. A transmission structure is movably sleeved on the air separation structure, and the output end of the transmission structure passes upward through the filter plate and extends above the filter plate. A bottom cleaning structure abuts the upper end of the filter plate and is in transmission connection with the output end of the transmission structure. A liquid pusher structure is mounted on the output end of the transmission structure, and a reset structure is connected to the upper portion of the liquid pusher structure. The reset structure is fixed to the upper left side of the treatment tank, and a discharge structure is disposed on the bottom surface of the discharge trough. This process can simultaneously ensure the filtering effect of the filter plate and the scum cleaning effect, and achieves a linkage effect, resulting in energy-saving and improved practicality.

[0004] In the prior art, when a filter plate is used to filter scum in wastewater, some residue will adhere to the water-proximal end of the sieve plate after a period of time. When these residues clog the sieve plate, a mechanical structure is used to drive a brush body for cleaning. This will cause the unloading structure to squeeze the waste residue into the sieve holes, causing blockage. It takes a lot of time to stop the machine and use a high-pressure water gun to flush.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1, reference Figure 1-8 A wastewater purification device for brewing wine includes a treatment box 1 and an upper water outlet 4 and a lower water outlet 6 located on both sides of the treatment box 1. An inclined plate 21 is installed at the middle position of the inner side of the treatment box 1, and the bottom position of the inclined plate 21 matches the position of the upper water outlet 4. A slot 11 is opened on the inclined plate 21, and a group of filter units are arranged in two adjacent slots 11.

[0028] The filter unit includes a first sieve plate 8 and a second sieve plate 30, and the size of the second sieve plate 30 is the same as that of the first sieve plate 8. A plurality of grooves 9 are evenly arranged on the upper end of the second sieve plate 30 and the first sieve plate 8 near the water, and a plurality of through-type sieve holes 10 are evenly arranged on the inner side of the grooves 9. A sieve 31 is arranged on the inner side of the sieve hole 10, and the sieve 31 in the sieve hole 10 is symmetrically arranged at the end positions on both sides of the sieve hole 10.

[0029] A sedimentation box 2 is fixedly installed on one side of the treatment box 1, and the sedimentation box 2 and the upper water outlet 4 are located on the same side of the treatment box 1. A partition 23 is fixed horizontally inside the sedimentation box 2, and the internal atmosphere of the sedimentation box 2 is divided into two independent spaces above and below through the partition 23. A through hole is opened on the side wall of the sedimentation box 2 below the partition 23, and the bottom of the sedimentation box 2 is connected with the inside of the treatment box 1 through the through hole.

[0030] When multiple first sieve plates 8 are located above the inclined plate 21, multiple second sieve plates 30 are located below the inclined plate 21, and when the first sieve plate 8 or the second sieve plate 30 is located below the inclined plate 21, multiple slots 11 are all located below the inclined plate 21, and a top cap 7 is fixedly installed on the top of the first sieve plate 8 and the second sieve plate 30. The lower end of the top cap 7 has the same inclination as the inclined plate 21, and the upper part of the top cap 7 is arc-shaped. When the first sieve plate 8 or the second sieve plate 30 is located below the inclined plate 21, the top cap 7 and the upper end surface of the inclined plate 21 fit each other.

[0031] A connecting frame 12 is provided on one side of the lower end of multiple first sieve plates 8 and the second sieve plates 30, and the connecting frames 12 connected to the first sieve plates 8 and the second sieve plates 30 are located on different sides. A regulating structure is provided at the lower end of the connecting frame 12, which includes a first eccentric wheel 16, a second eccentric wheel 17, a first lifting plate 18, a second lifting plate 19, a transmission shaft 15 and a motor 20. The transmission shaft 15 is connected to the end of the output shaft of the motor 20, and the motor 20 is fixed to the outside of the processing box 1. The second lifting plate 19 is connected between the bottom of the connecting frame 12 at the lower end of the first sieve plate 8, and the first lifting plate 18 is connected between the bottom of the connecting frame 12 at the lower end of the second sieve plate 30. The first eccentric wheel 16 and the second eccentric wheel 17 are respectively fixed on the outside of the transmission shaft 15, and the first eccentric wheel 16 and the second eccentric wheel 17 are respectively located at the lower ends of the second lifting plate 19 and the first lifting plate 18.

[0032] When the first eccentric wheel 16 pushes the second lifting plate 19 to rise to the highest point, the second eccentric wheel 17 pushes the first lifting plate 18 to the lowest point.

[0033] After the winemaking wastewater is concentrated, it is slowly injected from the upper side of the treatment box 1, that is, the wastewater enters the inclined plate 21 from the upper position of the inclined plate 21. The positions of the first eccentric wheel 16 and the second eccentric wheel 17 are adjusted by the rotation of the motor 20, so that the first eccentric wheel 16 pushes the second lifting plate 19 upward. At this time, the upper end parts of the multiple first sieve plates 8 are located above the inclined plate 21, and the liquid level of the incoming wastewater does not exceed the upper end height of the first sieve plate 8. The multiple second sieve plates 30 are located below the inclined plate 21. At this time The top cap 7 fixed on the upper end of the second sieve plate 30 blocks the position of the lower end slot 11. Secondly, the size of the lower end area of ​​the first sieve plate 8 and the slot 11 match each other, and the wastewater will not pass through the slot 11 and flow below the inclined plate 21. At this time, the wastewater will pass through the sieve hole 10 opened in the groove 9 on one side of the first sieve plate 8. During the process of passing through, the screen 31 is fixed at the end position of the screen hole 10, and the screen 31 near the water end blocks a large amount of scum, and the blocked scum gathers in the groove 9 on one side of the first sieve plate 8, and the particles Smaller yeast sludge and diatomaceous earth particles will pass through the screen 31 and enter the sedimentation tank 2 for subsequent separation. The advantage of the groove 9 as a scum storage is that it can collect more scum at a time. At the same time, after the first sieve plate 8 completes its filtering task and moves to the bottom of the inclined plate 21, when the first sieve plate 8 contacts both sides of the slot 11 during movement, the scum is located on the inner side of the groove 9, so the scum will not be scraped off during the descent of the first sieve plate 8. After the motor 20 is started, the first sieve plate 8 descends to the lowest point, and the second sieve plate 30 rises to the highest point. The motor 20 is turned off. At this time, clean water is introduced under the inclined plate 21 in the opposite direction of the wastewater flow. The scum originally filtered by the first sieve plate 8 is now located at the far end. The clean water flow below gradually washes away the scum and is gradually discharged with the water flow. The second sieve plate 30 above continues to filter. The two sieve plates alternately perform cleaning and filtering work, effectively maintaining long-term stable operation of the equipment.

[0034] Example 2, reference Figure 1 The difference between this embodiment and embodiment 1 is that a guide structure is provided between the connecting frame 12 and the bottom of the processing box 1, and the guide structure includes a guide hole 13 and a guide rod 14. The guide hole 13 is opened at the bottom position of the connecting frame 12, and the guide rod 14 is installed at the bottom of the processing box 1, and the upper end of the guide rod 14 passes through the guide hole 13 and extends to the upper position of the connecting frame 12. The sizes of the guide rod 14 and the guide hole 13 match each other.

[0035] When the first eccentric wheel 16 cooperates with the second lifting plate 19, and the second eccentric wheel 17 cooperates with the first lifting plate 18, the first screen plate 8 and the second screen plate 30 are driven to move up and down in the slot 11. In order to ensure that the first screen plate 8 and the second screen plate 30 do not tilt sideways when moving, a guide rod 14 is vertically arranged at the bottom of the processing box 1, and a guide hole 13 is opened at the bottom of the L-shaped connecting frame 12. The top of the guide rod 14 is passed through the guide hole 13. In this way, the mutual cooperation between the guide hole 13 and the guide rod 14 can effectively ensure that the first screen plate 8 and the second screen plate 30 will not deflect during the lifting process.

[0036] Example 3, reference Figure 1 and Figure 3 The difference between this embodiment and embodiment 1 and embodiment 2 is that a medicine box 3 is fixedly installed above the sedimentation box 2, and flocculant is pre-filled in the medicine box 3. A spherical groove 28 is provided between the medicine box 3 and the upper water outlet 4. A sphere 27 is rotatably provided on the inner side of the spherical groove 28. A round rod 25 is vertically installed on the upper end of the sphere 27. A movable plate 5 is fixedly installed on the lower end of the sphere 27, and a distance is set between the movable plate 5 and the bottom of the upper water outlet 4. A connecting rope 26 is installed on the round rod 25, and a baffle 29 is fixedly installed on the other end of the connecting rope 26, and the baffle 29 can be flipped and set at the bottom of the medicine box 3. The medicine box 3 is equipped with a leakage hole 22 for leaking materials, and when the baffle 29 is in the initial state, the baffle 29 covers the leakage hole 22. An elastic column 24 is connected between the top of the round rod 25 and the inner wall of the medicine box 3.

[0037] The yeast mud and diatomaceous earth entering the sedimentation tank 2 are mixed together, and the diatomaceous earth can be recycled after being processed. It is necessary to separate the diatomaceous earth from the yeast mud.

[0038] To this end, a deflectable movable plate 5 is provided on the inner side of the upper water outlet 4. When the movable plate 5 is impacted by the water flow, it will deviate to the side away from the treatment box 1. When the movable plate 5 is deflected, it drives the upper sphere 27 to rotate inside the spherical groove 28, and the diameter of the sphere 27 is larger than the diameters of the upper and lower ports of the spherical groove 28. At this time, the round rod 25 at the upper end of the sphere 27 will deflect toward the side close to the treatment box 1 along with the sphere 27. During the deflection process, the connecting rope 26 at the upper end of the round rod 25 will lift one side of the baffle 29 covering the multiple leakage holes 22, so that the flocculant inside the medicine box 3 can enter the sedimentation box 2 from the leakage hole 22. During this process, the falling coagulant will continue to mix with the flowing water.

[0039] Since the flocculation process is divided into a rapid mixing stage and a slow flocculation stage, when entering the flocculation stage, the wastewater stops being injected into the treatment box 1, and the movable plate 5 is not impacted by the water flow and will return to its initial position. In the initial state, the elastic member 24 and the connecting rope 26 are symmetrically arranged on both sides of the round rod 25. When the round rod 25 is deflected, the round rod 25 will compress the elastic member 24. After the external force on the movable plate 5 is removed, under the tension of the elastic member 24, the movable plate 5 returns to its initial position, and the baffle 29 is reset and blocks the leakage hole 22. The elastic member 24 can use a spring with an elastic recovery effect.

[0040] Replacing the traditional stirring structure and adding flocculants during the inflow of wastewater can also achieve the effect of sufficient mixing. At the same time, after the material is stratified in the later stage, compared with the traditional stirring structure, this structure does not form an obstruction in the stratified material. In this way, after the two stages of flocculation are completed, it is easy to remove the stratified material and the cleaning operation of the stirring equipment is eliminated.

[0041] The working principle of the device is: After the winemaking wastewater is concentrated, it is slowly injected from the upper side of the treatment box 1, that is, the wastewater enters the inclined plate 21 from the upper position of the inclined plate 21. The positions of the first eccentric wheel 16 and the second eccentric wheel 17 are adjusted by the rotation of the motor 20, so that the first eccentric wheel 16 pushes the second lifting plate 19 upward. At this time, the upper end parts of the multiple first sieve plates 8 are located above the inclined plate 21, and the liquid level of the incoming wastewater does not exceed the upper end height of the first sieve plate 8. The multiple second sieve plates 30 are located below the inclined plate 21. At this time The top cap 7 fixed on the upper end of the second sieve plate 30 blocks the position of the lower end slot 11. Secondly, the size of the lower end area of ​​the first sieve plate 8 and the slot 11 match each other, and the wastewater will not pass through the slot 11 and flow below the inclined plate 21. At this time, the wastewater will pass through the sieve hole 10 opened in the groove 9 on one side of the first sieve plate 8. During the process of passing through, the screen 31 is fixed at the end position of the screen hole 10, and the screen 31 near the water end blocks a large amount of scum, and the blocked scum gathers in the groove 9 on one side of the first sieve plate 8, and the particles Smaller yeast sludge and diatomaceous earth particles will pass through the screen 31 and enter the sedimentation tank 2 for subsequent separation. The advantage of the groove 9 as a scum storage is that it can collect more scum at a time. At the same time, after the first sieve plate 8 completes its filtering task and moves to the bottom of the inclined plate 21, when the first sieve plate 8 contacts both sides of the slot 11 during movement, the scum is located on the inner side of the groove 9, so the scum will not be scraped off during the descent of the first sieve plate 8. After the motor 20 is started, the first sieve plate 8 descends to the lowest point, and the second sieve plate 30 rises to the highest point. The motor 20 is turned off. At this time, clean water is introduced under the inclined plate 21 in the opposite direction of the wastewater flow. The scum originally filtered by the first sieve plate 8 is now located at the far end. The clean water flow below gradually washes away the scum and is gradually discharged with the water flow. The second sieve plate 30 above continues to filter. The two sieve plates alternately perform cleaning and filtering work, effectively maintaining long-term stable operation of the equipment.

[0042] When the first eccentric wheel 16 cooperates with the second lifting plate 19, and the second eccentric wheel 17 cooperates with the first lifting plate 18, the first screen plate 8 and the second screen plate 30 are driven to move up and down in the slot 11. In order to ensure that the first screen plate 8 and the second screen plate 30 do not tilt sideways when moving, a guide rod 14 is vertically arranged at the bottom of the processing box 1, and a guide hole 13 is opened at the bottom of the L-shaped connecting frame 12. The top of the guide rod 14 is passed through the guide hole 13. In this way, the mutual cooperation between the guide hole 13 and the guide rod 14 can effectively ensure that the first screen plate 8 and the second screen plate 30 will not deflect during the lifting process.

[0043] The yeast mud and diatomaceous earth entering the sedimentation tank 2 are mixed together, and the diatomaceous earth can be recycled after being processed. It is necessary to separate the diatomaceous earth from the yeast mud.

[0044] To this end, a deflectable movable plate 5 is provided on the inner side of the upper water outlet 4. When the movable plate 5 is impacted by the water flow, it will deviate to the side away from the treatment box 1. When the movable plate 5 is deflected, it drives the upper sphere 27 to rotate inside the spherical groove 28, and the diameter of the sphere 27 is larger than the diameters of the upper and lower ports of the spherical groove 28. At this time, the round rod 25 at the upper end of the sphere 27 will deflect toward the side close to the treatment box 1 along with the sphere 27. During the deflection process, the connecting rope 26 at the upper end of the round rod 25 will lift one side of the baffle 29 covering the multiple leakage holes 22, so that the flocculant inside the medicine box 3 can enter the sedimentation box 2 from the leakage hole 22. During this process, the falling coagulant will continue to mix with the flowing water.

[0045] Since the flocculation process is divided into a rapid mixing stage and a slow flocculation stage, when entering the flocculation stage, the wastewater stops being injected into the treatment box 1, and the movable plate 5 is not impacted by the water flow and will return to its initial position. In the initial state, the elastic member 24 and the connecting rope 26 are symmetrically arranged on both sides of the round rod 25. When the round rod 25 is deflected, the round rod 25 will compress the elastic member 24. After the external force on the movable plate 5 is removed, under the tension of the elastic member 24, the movable plate 5 returns to its initial position, and the baffle 29 is reset and blocks the leakage hole 22. The elastic member 24 can use a spring with an elastic recovery effect.

[0046] Replacing the traditional stirring structure and adding flocculants during the inflow of wastewater can also achieve the effect of sufficient mixing. At the same time, after the material is stratified in the later stage, compared with the traditional stirring structure, this structure does not form an obstruction in the stratified material. In this way, after the two stages of flocculation are completed, it is easy to remove the stratified material and the cleaning operation of the stirring equipment is eliminated.
