Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a dairy production wastewater treatment device. Background Art

[0002] A large amount of organic wastewater is generated in dairy production. Organic matter includes macromolecular proteins, fats, sugars, etc. These macromolecular organic matter easily aggregates in wastewater to form larger suspended matter. Therefore, in the treatment of organic wastewater from dairy production, these macromolecular suspended matter needs to be removed to prevent direct discharge that leads to environmental eutrophication and thus destroys the ecological balance.

[0003] After searching, a Chinese patent with announcement number: CN218146147U discloses an organic wastewater treatment device, including a wastewater treatment device body, a water inlet and a water outlet, wherein a water inlet is arranged on the upper side of one side of the wastewater treatment device body, and a first treatment chamber and a second treatment chamber are arranged inside the wastewater treatment device body, respectively, a filtering mechanism is arranged on one side of the first treatment chamber, and the filtering mechanism includes a mounting frame, a first filter plate, a second filter plate and an adsorption carbon layer, and the mounting frame is arranged between the first treatment chamber and the second treatment chamber.

DETAILED DESCRIPTION

[0030] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides a dairy production wastewater treatment device through improvement. The technical solution of the present invention is:

[0032] like Figures 1 to 8 As shown, an embodiment of the present invention provides a dairy production wastewater treatment device, including a filter cartridge 1 and a molecular sieve 2 and a partition 3 arranged inside the filter cartridge 1, the lower end of the filter cartridge 1 is connected to an output pipe 20 with a valve, and the upper end of the filter cartridge 1 is detachably mounted with a sealing cover 18, the upper end of the sealing cover 18 is inserted with an input pipe 19, and the interior of the partition 3 is provided with a suspended matter crushing device; the suspended matter crushing device includes a shell 4 inserted and fixed inside the partition 3, two pressurizing cylinders 5 are fixed to the inner side of the shell 4, the inner sides of the two pressurizing cylinders 5 are slidably connected with a slide cylinder 10, the upper ends of the two slide cylinders 10 are elastically connected with a slide rod 11 extending to the outside of the pressurizing cylinder 5, and the lower ends of the two slide rods 11 are fixed with a slide rod 11 slidably connected to the slide cylinder 10 The inner spring pressure plate 12, the lower ends of the two spring pressure plates 12 are connected with pressure springs 13, the lower ends of the two pressure springs 13 are respectively connected to the inner bottom ends of the two slide cylinders 10, one side of the lower end of the two pressure cylinders 5 is connected with a water inlet pipe 8 connected to the upper side of the partition 3, and the lower ends of the two pressure cylinders 5 are connected with a water outlet pipe 9, and a vibration crushing mechanism is arranged between the lower ends of the two water outlet pipes 9; a motor 6 is installed at the inner upper end of the outer shell 4, and a rotating shaft 7 is fixed to the driving end of the motor 6, and a reciprocating mechanism for driving the two slide bars 11 to move up and down alternately is arranged at the upper end of the rotating shaft 7, and a conducting mechanism is arranged at the lower end of the rotating shaft 7, which conducts the pressure cylinder 5 and the water outlet pipe 9 when the slide cylinder 10 is at the lowest point.

[0033] Furthermore, the reciprocating mechanism includes a rotating column 15 fixed to the upper end of the rotating shaft 7 and two sliding pins 14 fixed to one side of the upper ends of the two sliding rods 11. A guide groove 16 is provided on the outer side of the rotating column 15. The two sliding pins 14 are slidably connected to the inner side of the guide groove 16. The guide groove 16 includes two spiral inclined grooves 161, an upper arc groove 162 and a lower arc groove 163 (such as Figure 8 As shown in FIG. 1 ), the two ends of the upper arc groove 162 are respectively smoothly connected to the upper ends of the two spiral bevel grooves 161, and the two ends of the lower arc groove 163 are respectively smoothly connected to the lower ends of the two spiral bevel grooves 161, and the two spiral bevel grooves 161 are respectively located on opposite sides of the rotating column 15;

[0034] The reciprocating mechanism is used to drive the two slide bars 11 to move up and down alternately, so that the wastewater above the partition 3 can be alternately pumped into the inner side of the two pressure cylinders 5 for pressurization, and then the wastewater is alternately and quickly ejected to the inner side of the outlet pipe 9, thereby improving the crushing efficiency of suspended matter in the wastewater.

[0035] Furthermore, the conducting mechanism includes a driving pulley 101 fixed at the lower end of the rotating shaft 7, two circular cavities 102 (such as Figure 5As shown in the figure, a connecting hole 106 communicating with the inner side of the pressurizing cylinder 5 is provided at the position of the water outlet pipe 9 on the upper side of the two circular cavities 102, and a rotating plate 103 is rotatably connected to the inner side of the two circular cavities 102. A rotating plate hole 104 is provided at one side edge of the two rotating plates 103, and a driven pulley 105 located on the outer side of the pressurizing cylinder 5 is fixed to the lower side of the two rotating plates 103. The two driven pulleys 105 are connected to the driving pulley 101 through a synchronous belt, and the diameters of the driving pulley 101 and the driven pulley 105 are equal;

[0036] Through the conduction mechanism, the pressure cylinder 5 and the water outlet pipe 9 can be connected each time the slide cylinder 10 moves down to the lowest point, so that the high-pressure wastewater at the lower end of the inner side of the pressure cylinder 5 can be quickly sprayed to the inner side of the water outlet pipe 9 through the connecting hole 106 and the rotating plate hole 104 to crush the suspended matter. When the slide cylinder 10 is not at the lowest point, the pressure cylinder 5 and the water outlet pipe 9 are not connected, so that the wastewater pressure at the lower end of the inner side of the pressure cylinder 5 gradually increases, which is beneficial to increase the impact speed of the wastewater to the inner side of the water outlet pipe 9 and improve the crushing effect of the suspended matter.

[0037] Furthermore, a plurality of annular grooves 301 are formed on the inner sides of the two water outlet pipes 9, and connecting rods 302 are fixed on the inner sides of the two water outlet pipes 9, and a disc 303 is fixed on the outer sides of the two connecting rods 302 at the position corresponding to each annular groove 301;

[0038] When the wastewater flows into the inner side of the outlet pipe 9 rapidly, the wastewater and suspended matter can still hit the upper end surface of the disc 303 at a very high speed. After the collision, the suspended matter can be further crushed. The further crushed wastewater and suspended matter collide with the inner wall of the annular groove 301 at the corresponding position, and hit the suspended matter again. As the wastewater and suspended matter hit each disc 303 and the annular groove 301 in turn, the size of the suspended matter is greatly reduced and the size is more uniform, thereby improving the crushing effect of the suspended matter.

[0039] Furthermore, the vibration crushing mechanism includes two fixed pipes 204 fixedly connected to the lower ends of the two water outlet pipes 9, and two gear shafts 210 rotatably connected to the lower ends of the inner side of the housing 4. The lower ends of the two fixed pipes 204 are both provided with vibration pipes 201 (such as Figure 6As shown in the figure, a plurality of staggered vibration sheets 202 are fixed to the inner sides of the two vibration tubes 201, and a fixing ring 205 is fixed to the upper ends of the two vibration tubes 201. The two fixing rings 205 are rotatably connected to the outer sides of the two fixing tubes 204 through balls, and torsion springs 206 are fixed to the outer sides of the two fixing tubes 204. The lower ends of the two torsion springs 206 are fixedly connected to the outer sides of the two fixing rings 205, respectively. A convex block 207 is fixed to one side of the two fixing rings 205. A vibration wheel 208 is fixed to the upper ends of the two gear shafts 210. A plurality of toggling teeth 209 for toggling the convex block 207 are evenly fixed to the outer sides of the two vibration wheels 208, and a speed change driving mechanism is arranged between the two gear shafts 210.

[0040] Through the vibration crushing mechanism, when the wastewater flows through the vibration tube 201, the multiple vibration plates 202 in the vibration tube 201 can beat the wastewater at high frequency, causing a significant change in the water pressure in the area where the wastewater contacts the vibration plates 202, thereby forming a cavitation effect. The cavitation effect causes a large number of tiny bubbles to burst, and the burst bubbles can further break up the suspended matter, further reducing the size of the suspended matter, so that the suspended matter can be fully absorbed by the molecular sieve 2, thereby effectively preventing the molecular sieve 2 from being blocked by large-sized suspended matter.

[0041] Furthermore, the speed-changing drive mechanism includes a second motor 203 mounted at the bottom inner end of the housing 4 and two pinions 211 fixed to the outer sides of the two gear shafts 210. A large gear 212 is fixed to the driving end of the second motor 203. Both sides of the large gear 212 are meshed with the two pinions 211 through teeth.

[0042] Through the variable speed drive mechanism, the vibration wheel 208 can be driven to rotate at a higher angular velocity, so that the moving bump 207 can be pushed more times per unit time, thereby increasing the number of positive and negative rotations of the vibration tube 201 and the multiple vibration plates 202 inside it, and increasing the vibration frequency of the vibration tube 201 and the vibration plate 202, thereby increasing the intensity of the cavitation effect and improving the crushing effect of suspended matter in the wastewater.

[0043] Furthermore, one-way valves are provided on the inner sides of the two water inlet pipes 8, and the conducting directions of the two one-way valves are both directed to the inner side of the pressurizing cylinder 5;

[0044] Through the action of the one-way valve, the waste water in the space above the partition 3 can only flow into the inner side of the pressurizing cylinder 5 through the water inlet pipe 8 and cannot flow in the opposite direction, thereby ensuring that the pressure of the waste water inside the pressurizing cylinder 5 does not decrease.

[0045] Furthermore, the upper ends of the two slide cylinders 10 are provided with a plurality of air holes 17 (such as Figure 5 shown);

[0046] Through multiple air holes 17, when the pressure spring 13 pushes the slide 10 to move downward quickly to push the wastewater to the inside of the outlet pipe 9, the air between the pressure cylinder 5 and the slide 10 can circulate quickly with each other, preventing the gas from not flowing and generating air pressure, which will reduce the speed of the slide 10 moving downward, and prevent the flow rate of the wastewater to the inside of the outlet pipe 9 from being slowed down.

[0047] Working principle: when in use, the wastewater from dairy production is introduced into the space above the partition 3 inside the filter cartridge 1 through the input pipe 19, and then the large-sized suspended matter in the space above the partition 3 is crushed into small-sized suspended matter by the suspended matter crushing device and then transferred to the space below the partition 3, and then the small-sized suspended matter in the wastewater is adsorbed by the molecular sieve 2, so that the organic impurities in the wastewater can be filtered and treated, and the treated water is discharged through the output pipe 20;

[0048] When the suspended matter crushing device is in operation, the motor 16 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the rotating column 15 of the reciprocating mechanism to rotate, and the rotating column 15 drives the guide groove 16 on its outer side to rotate. Since the two spiral bevel grooves 161 are respectively located on the opposite sides of the rotating column 15, the upper arc groove 162 and the lower arc groove 163 can respectively cooperate with the two sliding pins 14 at the same time. As the rotating column 15 rotates, when the sliding pin 14 slides into the inner side of the upper arc groove 162 through the spiral bevel groove 161, the sliding pin 14 drives the sliding rod 11 to move up to the highest point. When the sliding pin 14 slides into the inner side of the lower arc groove 163 through the spiral bevel groove 161, the sliding pin 14 drives the sliding rod 11 to move down to The lowest point, therefore, with the continuous rotation of the rotating column 15, the two sliding bars 11 can be driven to move up and down alternately. When the sliding bar 11 moves up, the spring pressure plate 12 pulls the sliding cylinder 10 up, so that the waste water in the space above the partition 3 is sucked into the inner lower end of the pressure cylinder 5 through the water inlet pipe 8. When the sliding bar 11 moves down, it compresses the pressure spring 13 through the spring pressure plate 12. Since the waste water is incompressible, when the pressure spring 13 is compressed, the sliding cylinder 10 will not move downward. The sliding cylinder 10 can transfer the pressure from the pressure spring 13 to the waste water below it, thereby increasing the water pressure of the waste water at the inner lower end of the pressure cylinder 5. As the rotating shaft 7 rotates, the rotating shaft 7 The lower end drives the driving pulley 101 of the conducting mechanism to rotate synchronously. Since the diameters of the driving pulley 101 and the driven pulley 105 are equal, when the driving pulley 101 rotates, the two driven pulleys 105 are driven to rotate synchronously through the synchronous belt, thereby driving the two rotating plates 103 to rotate synchronously. When the rotating shaft 7 and the rotating column 15 rotate one circle, the two rotating plates 103 also rotate one circle. Therefore, whenever the guide groove 16 on the outer side of the rotating column 15 drives one of the slide bars 11 to move down to the lowest point, the rotating plate hole 104 on the side of the rotating plate 103 close to the slide bar 11 can be aligned with the connecting hole 106, so that the rotating plate hole 10 4 and the connecting hole 106 connect the inner side of the pressurizing cylinder 5 with the outlet pipe 9. At the moment of connection, under the action of huge water pressure, the wastewater at the lower end of the inner side of the pressurizing cylinder 5 can quickly flow into the inner side of the corresponding outlet pipe 9. When more wastewater flows into the inner side of the outlet pipe 9 with a smaller inner diameter at a very high speed, the suspended matter formed by the aggregation of macromolecular organic matter in the wastewater will collide and squeeze with the upper end of the outlet pipe 9, so that the suspended matter can be crushed and the size of the suspended matter can be reduced, so that the small-sized suspended matter can be more fully absorbed by the molecular sieve 2, effectively avoiding the large-sized suspended matter from clogging the molecular sieve 2, and improving the treatment effect of dairy wastewater;

[0049] When the wastewater flows into the inner side of the outlet pipe 9 quickly, the wastewater and the suspended matter can also hit the upper end surface of the disc 303 at a very high speed. After the collision, the suspended matter can be further crushed. The further crushed wastewater and the suspended matter collide with the inner wall of the annular groove 301 at the corresponding position, and the suspended matter is hit again. As the wastewater and the suspended matter hit each disc 303 and the annular groove 301 in turn, the size of the suspended matter is greatly reduced and the size is more uniform, thereby improving the crushing effect of the suspended matter.

[0050] The wastewater flowing through the outlet pipe 9 will continue to flow into the inner side of the vibration pipe 201 of the vibration crushing mechanism. The motor 203 of the variable speed drive mechanism drives the large gear 212 to rotate. The large gear 212 drives the two small gears 211 to rotate at a higher angular speed through the meshing of the teeth. The two small gears 211 drive the two gear shafts 210 of the vibration crushing mechanism to rotate at a high speed. The two gear shafts 210 respectively drive the two vibration wheels 208 to rotate synchronously. The two vibration wheels 208 respectively drive the multiple toggle teeth 209 on the outside to rotate at a high speed. When each toggle tooth 209 contacts the protrusion 207, it can give the protrusion 207 a positive rotation. 7 applies a thrust, and the protrusion 207 drives the fixing ring 205 to rotate a certain angle after receiving the thrust, and the fixing ring 205 drives the vibration tube 201 at the lower end to rotate a certain angle, and the vibration tube 201 drives the multiple vibration plates 202 inside thereof to rotate a certain angle. When the fixing ring 205 rotates, it can drive the lower end of the torsion spring 206 to rotate a certain angle, so that the torsion spring 206 generates elastic force. When the toggle tooth 209 is separated from the protrusion 207, the torsion spring 206 releases the elastic force, drives the fixing ring 205 to rotate in the reverse direction quickly to reset, and drives the vibration tube 201 to rotate in the reverse direction at the same time, and the vibration tube 201 drives the inner The multiple vibration plates 202 rotate in the opposite direction to reset. As the vibration wheel 208 drives the multiple toggle teeth 209 on the outside to rotate at a high speed, the multiple toggle teeth 209 can drive the fixed ring 205 and the vibration tube 201 to rotate forward and reverse at a very high frequency. The vibration tube 201 drives the multiple vibration plates 202 on the inside to rotate forward and reverse at a high frequency, which has a vibration effect. When wastewater flows through the inside of the vibration tube 201, the multiple vibration plates 202 vibrating at a high frequency can beat the wastewater. When the vibration plate 202 rotates quickly to one side, the side opposite to the rotation direction is quickly separated from the wastewater, so The pressure on the side where the vibration plate 202 is separated from the wastewater is greatly reduced. When the pressure is reduced to below the saturated vapor pressure of water, a large number of tiny bubbles will be generated in the water. When the vibration tube 201 and the vibration plate 202 rotate in the opposite direction, the side of the vibration plate 202 that was originally separated from the water is quickly squeezed with the water to break the bubbles. A large number of bubbles can burst, thereby forming a cavitation effect. A large number of burst bubbles can further break up the suspended matter and further reduce the size of the suspended matter, so that the suspended matter can be further fully absorbed by the molecular sieve 2, thereby effectively avoiding the molecular sieve 2 from being blocked by large-sized suspended matter.

[0051] The two slide bars 11 are driven to move up and down alternately by the reciprocating mechanism, so that the two pressure cylinders 5 can alternately draw in wastewater, and then squeeze the wastewater into the space below the partition 3, thereby improving the crushing efficiency of suspended matter in the wastewater.
