Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and specifically discloses a wastewater treatment device for meat cake processing. Background Technology

[0002] Meat cake is a traditional specialty cake food, and meat cakes from different regions have their own unique characteristics in terms of raw materials, methods, and taste. During the processing of meat cakes, a large amount of wastewater is generated in the core processes such as washing the raw materials, making the meat cakes, and cleaning the equipment. The conventional treatment method is to first pre-treat the production wastewater to remove suspended solids and oily substances, and then carry out biochemical treatment. Through the treatment of hydrolysis acidification tanks and biological contact oxidation tanks, the organic pollutants in the wastewater are decomposed into inorganic substances, and finally, a biofilm deep purification treatment is carried out.

[0003] Suspended solids are usually pretreated using air flotation, which utilizes the adhesion and buoyancy between air bubbles and pollutants such as colloidal particles and suspended solids in wastewater to remove these pollutants from the water.

[0004] However, the bubbles generated by the air flotation method are prone to collision and breakage. After the bubbles break, the attached particles are scattered back into the wastewater, affecting the effect of air flotation in removing pollutants from the wastewater. In addition, some colloidal particles and suspended solids are prone to precipitate together with large particulate impurities, affecting the air flotation treatment effect of pollutants such as colloidal particles and suspended solids.

[0005] Therefore, existing wastewater treatment equipment cannot meet the needs of actual use, so there is an urgent need for improved technologies to solve the above problems. Summary of the Invention

[0009] Preferably, a sealing plate is slidably connected inside the jet box, a spring three is fixedly connected to the lower end of the sealing plate, and the end of the spring three away from the sealing plate is in movable contact with the inner bottom wall of the treatment box.

A sealing groove is opened on the side wall of the jet box, and the upper stop block is slidably engaged with the sealing groove. A lower stop block is fixedly connected to the inner bottom wall of the treatment box, and the upper stop block and the lower stop block are in movable contact.

[0010] Preferably, a push rod is fixedly connected to the upper end of the sealing plate at the position corresponding to each jet protrusion. A breathable membrane is sleeved on the outside of the push rod, and a slip ring is provided inside the breathable membrane. The slip ring is slidably connected to the push rod. A second ear plate is fixedly connected to the outer wall of the slip ring. An ear plate is fixedly connected to the outer wall of the push rod above the slip ring.

A second connecting rod is hinged to the second ear plate, and the other end of the second connecting rod is hinged to the first connecting rod. A fixing ring is also fixedly connected to the outside of the push rod. A spring is fixedly connected between the fixing ring and the slip ring.

[0011] Preferably, the material turning assembly includes a material turning component, a separation box, and a filter screen. One end of the separation box is fixedly connected to the air inlet pipe, and the material turning component is fixedly connected to the side wall of the separation box.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of structures such as baffles and sealing plates, the baffles and sealing plates can rotate and stir, driving the wastewater to flow, so that large particulate impurities and pollutants such as suspended solids and colloidal particles are agitated and separated. When the suspended solids and colloidal particles are pretreated by air flotation, the baffles and sealing plates can remain stationary, forming multiple radially closed guiding channels, reducing the collision and breakage of bubbles, and improving the pretreatment effect of suspended solids, colloidal particles and other pollutants.

[0014] 2. By setting up the jet convex ball, since the upper and lower ends of the jet convex ball are conical arc surfaces and the middle is wider and the ends are narrower, the generated bubbles have a certain distance between them, which reduces bubble collision and reduces the contact area between the bubbles and the jet convex ball, allowing the bubbles to separate from the jet convex ball more quickly. On the one hand, this avoids the formation of large bubbles, which would cause the buoyancy to rise too quickly, resulting in insufficient surface tension and easy breakage. On the other hand, it reduces the contact time between the bubbles and the surface of the jet convex ball, avoiding the adhesion and breakage of the bubbles.

[0015] 3. By setting up structures such as top rods and breathable membranes, the air outlets of the air jet ball can be cleaned intermittently, avoiding the blockage of the air jet ball from affecting bubble generation, and also avoiding uneven bubble size, which would make the bubbles easy to break.

[0016] 4. By incorporating components such as the tipping mechanism and separation chamber, the wastewater at the bottom can be agitated, separating large particles from suspended solids and colloidal particles. On the other hand, it causes suspended solids and colloidal particles to rise, improving their adhesion to air bubbles. Large particles can be collected separately in the separation chamber, preventing them from causing suspended solids and colloidal particles to settle again, thus affecting the adhesion of pollutants such as suspended solids and colloidal particles to air bubbles.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] Please see Figure 1-14As shown, the present invention is a wastewater treatment device for meat cake processing, including a treatment tank 1, a support rod 7, and an air inlet pipe 13. The air inlet pipe 13 is rotatably connected to the bottom of the treatment tank 1. An air jet assembly 3 and a material turning assembly 4 are fixedly connected to the air inlet pipe 13. The air jet assembly 3 is used to spray gas into the wastewater to form bubbles, thereby adsorbing suspended solids and colloidal particles in the wastewater and bringing the suspended solids and colloidal particles to the top of the treatment tank 1. The suspended solids and colloidal particles are scraped off by a scraper structure. The scraper structure is a conventional technology in the field and will not be described in detail here. The material turning assembly 4 is used to turn the suspended solids and colloidal particles at the bottom of the treatment tank 1 upward, so that the suspended solids and colloidal particles are initially separated from large particulate impurities, and the suspended solids and colloidal particles can be more effectively adsorbed by the bubbles and carried upward.

[0022] The two ends of the support rod 7 are fixed to the inner wall of the processing box 1, and the connecting rod 6 is rotatably installed in the middle position. The lower end of the connecting rod 6 is rotatably connected to the air intake pipe 13, and the connection is provided with a one-way ratchet structure. The one-way ratchet structure allows the connecting rod 6 to rotate in one direction only with the air intake pipe 13. The one-way ratchet structure is also the prior art in this field. The flow stabilizing component 5 is provided below the support rod 7.

[0023] The flow stabilizing assembly 5 includes a baffle plate 17 and a sealing plate 2. The baffle plate 17 is fixed to the outside of the connecting rod 6. A rotating groove 18 is provided at the edge of the baffle plate 17. A shaft 19 is rotatably connected inside the rotating groove 18. The sealing plate 2 is sleeved on the outside of the shaft 19, and a torsion spring is installed between the sealing plate 2 and the baffle plate 17. One end of the sealing plate 2 is provided with a bent part 22, which movably abuts against the baffle plate 17. When it is necessary to effectively separate suspended solids, colloidal particles and other large particulate impurities in the wastewater, the air inlet pipe 13 rotates, which drives the baffle plate 17 to rotate through the connecting rod 6, thereby driving the wastewater flow and accelerating the separation of suspended solids, colloidal particles and other large particulate impurities. The separation efficiency of impurities is improved, and the suspended solids and colloidal particles at the bottom are turned upward. When it is necessary to maintain the stable flow of wastewater as much as possible, the baffle 17 cannot rotate with the air inlet pipe 13. The cooperation between the baffle 17 and the sealing plate 2 can guide the water flow, so that the bubbles can flow along the guide space between the baffle 17 and the sealing plate 2, which minimizes the chaotic flow and rise of the bubbles and reduces the collision and breakage between the bubbles. Because after the bubbles break, the attached particles are scattered back into the wastewater, which affects the effect of removing pollutants from the wastewater. It can also form a stable flow state, reduce the intensity of turbulence, and reduce the damage of the water flow shear force to the bubbles.

[0024] The spoiler 17 is provided with a mounting groove 20, and a magnet 21 is fixedly connected inside the mounting groove 20. The bent part 22 is provided with a mounting groove 24, and a magnet 23 is fixedly connected inside the mounting groove 24. The setting of magnet 21 and magnet 23 can make the bent part 22 of the sealing plate 2 fit tightly with the side wall of the spoiler 17, thereby sealing the adjacent spoilers 17 in the radial direction, forming multiple independent flow channels, reducing the influence of the external lateral water flow on the bubbles when the bubbles flow upward in the flow channels, and preventing the bubbles from being broken by the shear force of the water flow.

[0025] It also includes a motor 8 and a connecting pipe 16. The bottom end of the treatment box 1 is fixedly connected to a bottom column 9 and rotatably connected to a gear 10. The outside of the air inlet pipe 13 is fitted with a gear 2 12, which meshes with the gear 10. When the motor 8 starts, it drives the gear 10 and gear 2 12 to mesh and drive the air inlet pipe 13 to rotate. When the air inlet pipe 13 drives the jet assembly 3 on it to rotate, it can make the bubbles more evenly distributed inside the wastewater, improve the adhesion effect of bubbles with suspended solids, colloidal particles and other pollutants. When the jet assembly 3 rotates, the centrifugal force makes it easier for the bubbles to detach from the jet assembly, which will further reduce the breakage of bubbles, thereby improving the pretreatment effect of wastewater. When the air inlet pipe 13 rotates, it will also drive the turning assembly 4 to rotate, thereby turning the suspended solids, colloidal particles and other pollutants at the bottom of the treatment box 1 upward, which is conducive to the adhesion of bubbles with suspended solids, colloidal particles and other pollutants.

[0026] The air intake pipe 13 is internally fitted with a connecting pipe 16, which is used to connect to the external air supply structure. The bottom of the treatment box 1 is also fixedly connected with a drain valve 11, a slag discharge valve 14, and a branch pipe fitting 15. The drain valve 11 and the slag discharge valve 14 are used to discharge wastewater and pollutant slag, respectively. The connecting pipe 16 is fixedly connected to the branch pipe fitting 15, which is used to support and fix the connecting pipe 16. The output end of the motor 8 is fixedly connected to the gear 10.

[0027] The jet assembly 3 includes a jet box 35, a sealing plate 36, and jet convex balls 30. The jet box 35 is fixedly connected to and communicates with the outer wall of the air intake pipe 13. Multiple jet convex balls 30 are fixedly connected to the upper surface of the jet box 35. The upper and lower ends of the jet convex balls 30 are conical arc surfaces, wider in the middle and narrower at both ends. The wider middle and narrower at both ends ensure that there is a certain distance between the generated bubbles, reducing bubble collision and reducing the contact area between the bubbles and the jet convex balls 30, so that the bubbles separate from the jet convex balls 30 more quickly. On the one hand, this avoids the formation of large bubbles, which would cause the buoyancy to rise too quickly, resulting in insufficient surface tension and easy breakage. On the other hand, it reduces the contact time between the bubbles and the surface of the jet convex balls 30, preventing the bubbles from adhering to and breaking.

[0028] A sealing plate 36 is slidably connected inside the jet box 35. A spring 33 is fixedly connected to the lower end of the sealing plate 36. The end of the spring 33 away from the sealing plate 36 is in movable contact with the inner bottom wall of the treatment box 1. An arc-shaped plate 33 is fixedly connected to the upper end of the sealing plate 36. An upper stop block 29 is fixedly connected to the side wall of the sealing plate 36 at the arc-shaped plate 33. A sealing groove 34 is opened on the side wall of the jet box 35. The upper stop block 29 is slidably engaged with the sealing groove 34. A lower stop block 28 is fixedly connected to the inner bottom wall of the treatment box 1, and the upper stop block 29 and the lower stop block 28 are in movable contact. When the jet box 35 rotates, it can drive the sealing plate. When the upper stop 29 on the sealing plate 36 rotates, and the lower stop 28 contacts the sealing plate 36, the mutual compression will cause the upper stop 29 to drive the sealing plate 36 to move upward inside the jet box 35. Then, under the action of the spring 353, it moves downward to reset. During the upward movement, the sealing plate 36 will drive the push rod 37 to move upward, thereby pushing out the contaminants attached to the jet nozzle on the jet ball 30, avoiding the blockage of the jet ball 30 from affecting the generation of bubbles. At the same time, it achieves the cleaning of the jet nozzle of the jet ball 30, avoiding uneven bubble size and easy breakage of the generated bubbles.

[0029] It should be noted that only one connection structure of the push rod 37 is shown in Figure 11 for the purpose of showing the whole view more concisely and for easy viewing. The upper end of the sealing plate 36 is fixedly connected to the push rod 37 at the position corresponding to each jet ball 30. The push rod 37 is covered with a breathable membrane 38. The breathable membrane 38 is provided with a slip ring 45 inside. The slip ring 45 is slidably connected to the push rod 37. The outer wall of the slip ring 45 is fixedly connected with a second ear plate 54. The outer wall of the push rod 37 is fixedly connected with a first ear plate 41 above the slip ring 45. The bottom edge of the breathable membrane 38 is fixedly connected with a fixing buckle 43. The first ear plate 41 is hinged to a first connecting rod 42. The other end of the first connecting rod 42 is hinged to the fixing buckle 43. The second ear plate 54 is hinged to a second connecting rod 44. The other end of the second connecting rod 44 is hinged to the first connecting rod 42. The outside of the push rod 37 is also fixedly connected with a fixing ring 39. A first spring 40 is fixedly connected between the fixing ring 39 and the slip ring 45.

[0030] The diameter of the push rod 37 is smaller than the diameter of the air nozzle of the jet ball 30, making it easier for the top of the push rod 37 to be pushed into the air nozzle. However, precisely because the diameter of the push rod 37 is smaller than the diameter of the air nozzle of the jet ball 30, when the push rod 37 pushes out the contaminants from the air nozzle, it cannot completely cover the air nozzle, causing some contaminants to fall into the air box 35, affecting the subsequent air jet effect. Therefore, this application further incorporates a mechanism that allows the push rod to work in conjunction with the connecting rod 42, the connecting rod 44, and the spring 40. In the initial state, the spring 40 pushes the slip ring 45 upward, causing the slip ring 45 to rotate outward via the connecting rod 44. The connecting rod 42 expands the breathable membrane 38. When the top rod 37 moves upward, it moves the opened breathable membrane 38 into the air outlet of the air jet ball 30. Since the diameter of the air outlet is small, the breathable membrane 38 will contract under the pressure of the air outlet. At this time, the breathable membrane 38 will completely cover the air outlet, and then push out the blockage in the air outlet.

[0031] The permeable membrane 38 allows the push rod 37 to clean the air outlet of the air jet ball 30. When the permeable membrane 38 opens, it can completely cover the air outlet, pushing the contaminants outward and preventing them from falling into the air jet box 35. The permeable membrane 38 also allows airflow, and when cleaning contaminants, it can also spray gas outward to form bubbles, which does not affect the pretreatment of wastewater. Furthermore, when the gas is sprayed outward, it can also push the contaminants outward, providing auxiliary cleaning for the push rod 37 and reducing the amount of contaminants entering the air jet box 35.

[0032] The material turning assembly 4 includes a material turning component 27, a separation box 47, and a filter screen 46. One end of the separation box 47 is fixedly connected to the air inlet pipe 13. The material turning component 27 is fixedly connected to the side wall of the separation box 47. The material turning component 27 has a lifting surface 50 and a lifting surface 49. The lifting surface 50 is an outwardly convex arc surface, and the lifting surface 49 is an inwardly concave arc surface. The end of the lifting surface 49 is close to the upper opening of the separation box 47 and its height is higher than the upper opening of the separation box 47. Because large particulate impurities will also cause some suspended solids and colloidal particles to settle together during sedimentation, the suspended solids and colloidal particles are at the bottom of the treatment box 1, which prevents these suspended solids and colloidal particles from effectively adhering to the air bubbles. When the material turning component 27 rotates, it agitates the wastewater at the bottom, which on the one hand can... This allows large particulate impurities to separate from suspended solids and colloidal particles. On the other hand, it causes suspended solids and colloidal particles to tumble upwards, improving their adhesion to air bubbles. Furthermore, the convex arc-shaped surface of the lifting surface 50 can guide the contaminants at the bottom, allowing them to effectively tumble upwards along the lifting surface 50. The concave arc-shaped surface of the lifting surface 49 can lift the tumbled contaminants even higher, making it easier for air bubbles to adhere to the contaminants. Since the end of the lifting surface 49 is close to the upper opening of the separation box 47, large particulate impurities can tumble along the concave arc-shaped surface and enter the separation box 47 for separate collection, preventing them from causing suspended solids and colloidal particles to settle again.

[0033] A rotating rod 26 is rotatably connected inside the separation box 47. A filter screen 46 is sleeved on the outside of the rotating rod 26. A spring 48 is fixed between the filter screen 46 and the separation box 47. One end of the rotating rod 26 passes through the separation box 47 and is fixedly connected to a gear 32. A mating part 25 is fixedly connected to the inner bottom wall of the processing box 1. A gear 31 is fixedly connected to the mating part 25. The gear 31 and the gear 42 are meshed. A sliding groove 55 is opened on the inner bottom wall of the separation box 47. A baffle 52 is slidably connected in the sliding groove 55. A spring 4 is fixed between the baffle 52 and the sliding groove 55. A discharge port 51 is provided on the side wall of the separation box 47.

[0034] The filter screen 46 can filter and collect large particulate impurities, causing them to settle in the separation box 47. When the separation box 47 rotates, gear 31 meshes with gear 42, causing gear 42 to drive gear 31 to rotate. Gear 31 drives the filter screen 46 to swing through the rotating rod 26. When the filter screen 46 swings, it can shake off the impurities on the filter screen 46, reducing clogging and ensuring the filtration effect. On the other hand, it can shake off the large particulate impurities, suspended solids, colloidal particles and other pollutants inside the separation box 47 again, so that the suspended solids and colloidal particles can be separated from the large particulate impurities again. When the separation box 47 rotates, the baffle 52 extends outward from the slide 55 under the action of centrifugal force, thereby blocking the discharge port 51 and preventing the collected large particulate impurities from flowing out. After the pretreatment of suspended solids, colloidal particles and other pollutants is completed, the separation box 47 stops rotating, the baffle 52 retracts into the slide 55, and the discharge port 51 opens, so that the large particulate impurities inside the separation box 47 can be discharged.

[0035] Working principle: When motor 8 starts, it drives gear 10 and gear 2 to mesh and drive the air intake pipe 13 to rotate. At this time, no air is sprayed into the wastewater. When the air intake pipe 13 rotates, the air jet assembly 3 and the material turning assembly 4 rotate, and drive the baffle 17 on the connecting rod 6 to rotate, which stirs the wastewater, so that large particulate impurities can be separated from pollutants such as suspended solids and colloidal particles. When the baffle 17 rotates, it can drive the sealing plate 2 to rotate. When the sealing plate 2 rotates, due to the centrifugal force, the bent part 22 on the sealing plate 2 will overcome the force of magnet 1 21, magnet 2 23 and torsion spring, so that the bent part 22 will disengage from the baffle 17. The bent part 22 opens and rotates, which improves the stirring effect of the wastewater. At the same time, the sealing plate 2 will collide with the inner wall of the treatment tank 1, so that turbulence can be formed inside the wastewater, which further improves the stirring effect of the wastewater, so that large particulate impurities can be effectively separated from pollutants such as suspended solids and colloidal particles. Then, air is sprayed into the wastewater through the connecting pipe 16, the air inlet pipe 13 and the jet box 35 to form bubbles. At this time, the motor 8 drives the air inlet pipe 13 to rotate in the opposite direction. Due to the one-way ratchet structure, the connecting rod 6 cannot rotate at this time. Under the action of the torsion spring, the bent part 22 on the sealing plate 2 will fit against the outer wall of the baffle 17. At the same time, under the attraction of magnet 1 21 and magnet 2 23, the stability of the bent part 22 fitting against the outer wall of the baffle 17 is improved. Multiple radially closed independent guide channels are formed between the baffle 17 and the sealing plate 2. Since the air inlet pipe 13 drives the bottom jet box 35 and the material turning assembly 4 to rotate at this time, the guide channels can reduce the flow of wastewater in the middle and upper parts to form a stable flow and reduce the collision and breakage of bubbles when they flow and rise inside the guide channels. When the jet box 35 rotates, the bubbles are distributed more evenly inside the wastewater, improving the adhesion of bubbles to pollutants such as suspended solids and colloidal particles. Furthermore, due to the centrifugal force, the bubbles are more likely to detach from the jet ball 30, further reducing the breakage of bubbles. At the same time, the rotation of the jet box 35 can drive the sealing plate 36 to rotate. When the upper stop 29 and the lower stop 28 on the sealing plate 36 come into contact, the mutual compression will cause the upper stop 29 to drive the sealing plate 36 to move upward inside the jet box 35. Then, under the action of the spring 33, it moves downward to reset. During the upward movement of the sealing plate 36, it will drive the push rod 37 to move upward, thereby pushing out the pollutants attached to the jet nozzle on the jet ball 30, avoiding blockage of the jet nozzle of the jet ball 30, affecting the uniform generation of bubbles, and reducing the breakage of bubbles. When the tilting component 27 rotates, it can agitate the wastewater at the bottom. On the one hand, it can separate large particles of impurities from suspended solids and colloidal particles. On the other hand, it can cause suspended solids and colloidal particles to turn upward, improving the adhesion effect between suspended solids and colloidal particles and air bubbles. It can also guide large particles of impurities into the separation box 47, where they are collected separately, preventing them from causing suspended solids and colloidal particles to settle again. When the separator 47 rotates, gear 31 meshes with gear 42, causing gear 42 to drive gear 31 to rotate. Gear 31 drives the filter screen 46 to swing through the rotating rod 26. When the filter screen 46 swings, it can shake off the impurities on the filter screen 46, reduce clogging and ensure the filtration effect. On the other hand, it can shake off large particulate impurities, suspended solids, colloidal particles and other pollutants inside the separator 47 again, so that suspended solids and colloidal particles can be separated from large particulate impurities again, improving the pretreatment effect of suspended solids, colloidal particles and other pollutants.
