Description

Technical Field

[0001] The present invention relates to the technical field related to wastewater treatment, and in particular to wastewater filtering equipment for producing A2 type β-casein high-calcium condensed milk. Background Art

[0002] A2 β-casein high-calcium condensed milk is a dairy product made from milk containing only A2 β-casein, which is concentrated to enhance the calcium content. It is mainly used to meet the nutritional needs of people with sensitive digestion and those who need calcium supplementation, while reducing gastrointestinal discomfort.

[0003] In the production process of A2 β-casein high-calcium condensed milk, raw milk inspection and cooling are essential steps. However, these two steps generate flushing wastewater. This wastewater contains a certain amount of milk fat particles and A2 β-casein residues. From a chemical composition perspective, A2 β-casein has a high nitrogen content, while milk fat also contains a significant amount of phosphorus. If this wastewater is discharged directly into natural water bodies without effective treatment, it will cause a series of serious environmental problems. First, nitrogen and phosphorus levels in the water body will quickly exceed the standard, providing ample nutrients for the proliferation of algae, leading to explosive algal blooms and other phenomena, seriously disrupting the ecological balance of the water body and affecting its appearance and normal use. Second, the decomposition of milk fat requires a large amount of oxygen, which can cause a sharp drop in dissolved oxygen levels in the water body, resulting in hypoxia. This hypoxia can endanger the survival of aquatic organisms such as fish, even leading to mass mortality, and in turn devastating the entire aquatic ecosystem.

[0004] After searching, announcement number CN213112791U discloses a wastewater filtration mechanism for titanium dioxide production with slag-water separation and filtration functions, including: passing the wastewater from the first water inlet pipe into the slag-water separation box, separating the slag and water in the wastewater through the coarse filter mesh plate, and driving the auger to rotate by the motor to stir the slag and water in the slag-water separation box to avoid blockage. The wastewater after filtering out the slag enters the filter tower, and deeply filters the wastewater through the fine filter mesh plate. The suspended particulate impurities in the wastewater are then adsorbed by the activated carbon adsorption plate. Finally, the valve on the drain pipe is opened to discharge the filtered wastewater, and the cleaning pipe is connected to the external water source. The inside of the filter tower can be cleaned by spraying through the cleaning nozzle.

[0005] However, in actual use, as the filtration process continues, a large amount of impurity particles will inevitably accumulate on the filter. These accumulated particles will gradually form an obstruction layer, seriously affecting the normal filtration function of the filter. Specifically, the filtration rate is significantly slowed down, and the wastewater that could originally pass through the filter quickly now takes longer to complete the filtration process. What is more serious is that when too many impurity particles accumulate on the filter, it will cause the filter to be clogged, making it impossible for the wastewater to pass through the filter smoothly, resulting in a significant reduction in the efficiency of the entire filtration system, or even failure to work normally, causing great trouble to wastewater treatment. Summary of the Invention

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a wastewater filtration device for the production of A2 type β-casein high-calcium condensed milk, comprising: a filter box, the inner side of which is sealed with a filter cartridge, and the outer side is connected in sequence with an inlet pipe, a cleaning pipe and a drain pipe; a driving component for providing power to the filter cartridge is provided on the outer side of the filter box; wastewater enters through the water inlet pipe, is filtered by the filter cartridge, and enters its inner cavity, and finally flows out from the cleaning pipe and the drain pipe respectively; as the filter cartridge continuously rotates, the wastewater output into the cleaning pipe realizes continuous backwashing and clearing of the filter part of the filter cartridge.

[0008] Furthermore, a dirt storage pipe connected to the water inlet pipe is fixedly installed on the side of the filter box, and the top of the dirt storage pipe is slidably connected to the outer side of the filter cartridge.

[0009] Furthermore, a filter element with the same filter diameter as the filter cartridge is fixedly installed at the end of the drain pipe.

[0010] Furthermore, the first driving component includes: fan blades, which are movably installed in the cleaning pipe, and the fan blades and the rotating shafts of the filter cartridge are fixedly installed with pulleys, and the pulleys are connected by belt transmission.

[0011] Furthermore, the internal sealing movable sleeve of the sewage storage pipe is provided with a detection seat pushed by a spring, and a valve plate assembly is installed in the middle of the cleaning pipe and above the fan blades. The regulating piston cylinder fixed in the cleaning pipe is used to realize the connection / disconnection of the valve plate assembly; the regulating piston cylinder and the inner cavity of the sewage storage pipe are connected by the regulating pipe.

[0012] Furthermore, a reset piston rod pushed by a spring is sealed on the inner side of the regulating piston cylinder, a guide groove is provided on the outer side of the middle part of the regulating piston cylinder, and a connecting piston arm fixed to the valve plate assembly is fixedly installed on the end of the reset piston rod. When the reset piston rod moves, the valve plate assembly is connected / disconnected by the connecting piston arm; the end of the connecting piston arm is movably sheathed with a detection piston rod pushed by a spring, and the detection piston rod is sealed with the inner cavity of the regulating piston cylinder.

The clean, filtered wastewater smoothly enters the filter cartridge and is then discharged in an orderly manner through a drain pipe on the other side, completing the initial wastewater purification process.

[0018] After the filter cartridge's exterior has completed filtering, some large impurities will adhere to the cartridge's surface. The top of the sewage pipe scoops these large impurities, eventually dropping them into the pipe's interior, achieving initial collection and separation. For particles clogged on the outside of the filter cartridge, when the cartridge rotates to the cleaning drain, purified wastewater from the interior is discharged through the drain, clearing the clogged particles through backflushing. This ultimately achieves real-time backflushing and clearing, ensuring the long-term stability and filtration efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] For example 1, please refer to Figure 1 and Figure 2 It can be seen that the filter box 1 serves as the main support of the entire component, and the internal sealing movable sleeve is equipped with a filter cartridge 5, and a driving component for rotating the filter cartridge 5 is provided on the outside of the filter box 1, such as a motor 4 fixed on the outside of the filter box 1 and arranged coaxially with the filter cartridge 5. The motor 4 can drive the filter cartridge 5 to rotate continuously.

[0024] A water inlet pipe 101 is fixedly installed on the side of the filter box 1. The water inlet pipe 101 is generally connected to a water pump. The water pump is used to suck the wastewater generated during the production of A2 type β casein high calcium condensed milk and transport it to the inside of the filter box 1 through the water inlet pipe 101. During this process, the wastewater first passes through the filter cartridge 5, and the outer side of the filter cartridge 5 is used to effectively filter the wastewater. The filtered impurities are placed on the outside of the filter cartridge 5, and the filtered pure wastewater enters the inside of the filter cartridge 5. Figure 2 It can be seen that a drain pipe 102 is fixedly installed on the side of the filter box 1 and arranged symmetrically with the water inlet pipe 101. The purified waste water in the filter cartridge 5 can be discharged outward from the drain pipe 102. In order to clean the particulate matter accumulated on the outer side of the filter cartridge 5, Figure 2 It can be seen that the side of the filter box 1 is fixedly installed with a sewage pipe 3 connected to the water inlet pipe 101, and the top of the sewage pipe 3 is slidably connected to the outer side of the filter cartridge 5. The advantage of this arrangement is that when the filter cartridge 5 rotates clockwise, the direction reference Figure 2 The impurities gathered on the outer side of the filter cartridge 5 are shoveled by the dirt storage pipe 3 and separated from the filter cartridge 5. Finally, the impurities fall into the dirt storage pipe 3 under gravity and are collected, preventing the accumulation of impurities on the outer side of the filter cartridge 5 and affecting the filtration efficiency.

[0025] Not only that, from Figure 1 and Figure 2 As can be seen in the figure, a cleaning drain pipe 103 is fixedly installed on the bottom of the outer side of the filter box 1, located between the drain pipe 102 and the water inlet pipe 101. The cleaning drain pipe 103 is connected to the inner cavity of the filter box 1 and is generally connected to a sewage tank or the inlet of a water pump. After the water pump transports wastewater to the water inlet pipe 101, the wastewater is filtered by the filter cartridge 5 and discharged out of the drain pipe 102.

[0026] Impurities will gather on the outside of the filter cartridge 5, but as the filter cartridge 5 continues to rotate, the impurities on the outside of the filter cartridge 5 are shoveled by the sewage storage pipe 3 and eventually fall into the inner cavity of the sewage storage pipe 3 for collection; after the impurities blocked in the filter cartridge 5 pass through the cleaning drain pipe 103, since the pure wastewater in the inner cavity of the filter cartridge 5 tends to be discharged toward the drain pipe 102 and the cleaning drain pipe 103, as the wastewater in the inner cavity of the filter cartridge 5 is discharged toward the cleaning drain pipe 103 through the filter cartridge 5, the pure wastewater is used to backwash the filtering part of the filter cartridge 5, thereby achieving real-time clearing of the filter cartridge 5 and ensuring that the filter cartridge 5 always maintains an efficient filtration state.

[0027] In this technology, Figure 1 and Figure 2As can be seen, a filter element 2 is secured to the end of the drain pipe 102 via a flange, and the filter diameter of the filter element 2 is the same as that of the filter cartridge 5. The advantage of this design is that, during prolonged use, friction between the filter box 1 and the filter cartridge 5 can cause a gap to form, causing some impurities to be unfiltered and discharged directly through the drain pipe 102. The provision of the filter element 2 ensures that the wastewater discharged from the drain pipe 102 is free of cream particles.

[0028] Example 2 provides another driving method, please refer to Figure 3 、 Figure 5 and Figure 6 It can be seen that a fan blade 13 is movably mounted in the middle of the cleaning pipe 103. When wastewater is discharged from the cleaning pipe 103, the wastewater can drive the fan blade 13 to rotate. A pulley 6 located on the outer side of the cleaning pipe 103 is fixedly mounted on the rotating shaft of the fan blade 13. Correspondingly, a pulley 6 located on the outer side of the filter box 1 is fixedly mounted on the rotating shaft of the filter cartridge 5. The two pulleys 6 are connected by a belt 600. In this way, when the fan blade 13 drives the pulley 6 to rotate, the belt 600 can drive the filter cartridge 5 to rotate synchronously.

[0029] Since the filter box 1 and the filter cartridge 5 need to be sealed by sliding, a gap will be generated between them due to wear during long-term contact, thus affecting the filtering effect. In order to reduce the wear between the two, the second embodiment of the present invention is to Figure 4-Figure 6 It can be seen that the internal sealing sleeve of the sewage pipe 3 is equipped with a detection seat 14, and the detection seat 14 is pushed by the spring and has a tendency to move towards the water inlet pipe 101. Correspondingly, a valve plate assembly 12 is installed in the middle of the cleaning pipe 103 and above the fan blade 13. The valve plate assembly 12 consists of two relatively staggered valve plates, of which the valve plate at the bottom is installed on the piston rod of the regulating piston cylinder 8. The regulating piston cylinder 8 is adjusted from Figure 5 It can be seen that it is fixed in the cleaning pipe 103 and is located below the valve plate assembly 12, and the regulating piston cylinder 8 and the inner cavity of the sewage pipe 3 are connected by the regulating pipe 11. Under normal conditions, the valve plate assembly 12 is in a closed state. At this time, the detection seat 14 is pushed upward by the spring, and no wastewater will flow in the cleaning pipe 103, and the fan blade 13 will not rotate. The filter cartridge 5 will not rotate at this time and will focus on filtering the wastewater input from the water inlet pipe 101. Combined Figure 7It can be seen that a reset piston rod 801 is sealedly installed on the inner side of the regulating piston cylinder 8, and the reset piston rod 801 tends to move toward the middle of the regulating piston cylinder 8 under the influence of a spring. A guide groove is provided on the outer side of the middle of the regulating piston cylinder 8, and a connecting piston arm 803 is fixedly installed on the end of the reset piston rod 801. The connecting piston arm 803 is fixedly connected to a valve plate in the valve plate assembly 12. When the reset piston rod 801 moves, the connecting piston arm 803 can drive the valve plate assembly 12 to be connected or disconnected. In addition, a detection piston rod 802 is movably mounted on the end of the connecting piston arm 803, which is pushed by a spring. The two ends of the spring are fixedly connected to the detection piston rod 802 and the connecting piston arm 803 respectively. The detection piston rod 802 is sealed with the inner cavity of the regulating piston cylinder 8. When the regulating tube 11 transports the medium into the inner cavity of the regulating piston cylinder 8, it pushes the detection piston rod 802 to move in the direction of the reset piston rod 801 and compresses the spring.

[0030] It should be noted that a one-way air valve and a damping hole are provided at the end of the adjusting piston cylinder 8 and in the chamber on the side of the reset piston rod 801 to ensure that when the reset piston rod 801 extends outward and compresses the spring, the air flow inside the adjusting piston cylinder 8 can be quickly discharged from the one-way air valve, and when the reset piston rod 801 is reset by the spring, the damping hole can limit its movement speed.

[0031] from Figure 6As can be seen in the figure, a one-way liquid flow valve 17 is installed at the top of the inner side of the cleaning pipe 103 and above the valve plate assembly 12. This one-way liquid flow valve 17 ensures that the medium in the filter cartridge 5 flows unidirectionally into the cleaning pipe 103. The advantage of this design is that under normal conditions, the valve plate assembly 12 is in the blocked state. At this time, the medium in the filter cartridge 5 does not flow into the cleaning pipe 103, and the filter cartridge 5 does not rotate, which also reduces the wear caused by relative sliding between the filter cartridge 5 and the filter box 1. Wastewater input from the water inlet pipe 101 is filtered by the filter cartridge 5 and discharged from the drain pipe 102. After a long period of filtration, the filter cartridge 5 will gradually become clogged, which will slow down the rate of filtration of wastewater in the water inlet pipe 101. The water pump continuously transports the medium into the water inlet pipe 101, causing the wastewater pressure in the water inlet pipe 101 to increase, thereby pushing the detection seat 14 downward. The medium in the detection seat 14 will be transported to the regulating piston cylinder 8 through the regulating pipe 11, and push the detection piston rod 802 to compress the spring, and finally push the connecting piston arm 803 and the reset piston rod 801 to move to the left. During this process, the connecting piston arm 803 will drive the valve plate assembly 12 to open it. At the same time, the detection piston rod 802 crosses the guide groove, and the medium in the inner cavity of the sewage storage pipe 3 is pressurized and transported to the cleaning drain pipe 103, thereby increasing the medium in the cleaning drain pipe 103. When the medium passes through the fan blade 13, it tends to push the fan blade 13 to rotate. As the fan blade 13 drives the filter cartridge 5 to rotate through the pulley 6 and the belt 600, the filtering position of the filter cartridge 5 changes. Afterwards, the medium in the water inlet pipe 101 can be filtered again through the filter cartridge 5. At the same time, the filtered wastewater is discharged from the drain pipe 102 and the cleaning drain pipe 103, and the fan blade 13 continues to rotate. As the wastewater in the water inlet pipe 101 is filtered by the filter cartridge 5, the pressure on the water inlet pipe 101 is relieved. Finally, the detection seat 14 is pushed upward by the spring. However, at this time, the reset piston rod 801 is damped, which slows down the reset speed, causing the wastewater filtered by the filter cartridge 5 to pass through the cleaning drain pipe 103 and backwash the filter cartridge 5 to clear the blockage, ensuring that the cleaning drain pipe 103 can fully clear the filter area of the filter cartridge 5. In this process, in order to ensure that the detection seat 14 is reset, a one-way valve 111 connected to the external water pool is fixedly installed at the top of the regulating pipe 11. Even after the detection piston rod 802 blocks the regulating piston cylinder 8, the one-way valve 111 can be used to transport the external water medium to the inner cavity of the sewage storage pipe 3, ensuring that the detection seat 14 can move upward and reset. On this basis, by controlling the aperture of the one-way valve 111 , the rate of delivering the medium into the inner cavity of the sewage storage pipe 3 can be achieved, thereby controlling the upward reset speed of the detection seat 14 .

[0032] In the process of implementation, in order to prevent the medium transported from the sewage pipe 3 to the cleaning pipe 103 from being insufficient to rotate the fan blade 13, the fan blade 13 is rotated by the combination of the Figure 6It can be seen that the outer bottom of the sewage storage pipe 3 is connected to the cleaning discharge pipe 103 by a sewage connection pipe 10, and the sewage connection pipe 10 is located above the fan blade 13. Under normal circumstances, a sealing ring frame 15 pushed upward by a spring is movably installed at the bottom of the inner cavity of the sewage storage pipe 3, and the sealing ring frame 15 blocks the sewage connection pipe 10. When the filter cartridge 5 is blocked and the filtration is not smooth, the detection seat 14 will be caused to move downward. If the fan blade 13 does not start normally during the downward movement of the detection seat 14, the detection seat 14 will move further downward and eventually push the blocking ring frame 15 downward. When the detection seat 14 passes the blocking ring frame 15, the wastewater in the inner cavity of the sewage pipe 3 will be directly transported to the cleaning pipe 103 through the sewage connection pipe 10, which will cause the medium pressure in the cleaning pipe 103 to increase. Because the one-way liquid flow valve 17 has a one-way flow blocking function, the wastewater will only move downward and push the fan blade 13 to rotate. The rotation of the fan blade 13 will eventually cause the filter cartridge 5 to rotate synchronously. The rotation of the filter cartridge 5 will cause the filtration position to change. When the filtration position changes, the wastewater in the water inlet pipe 101 is filtered by the filter cartridge 5, thereby reducing the pressure in the inner cavity of the sewage pipe 3. The detection seat 14 is pushed upward by the spring, and the blocking ring frame 15 blocks the end of the sewage connection pipe 10 again. In this way, the fan blade 13 is guaranteed to have a stronger rotation driving force. Subsequently, the fan blades 13 drive the filter cartridge 5 to further rotate according to the above content until the reset piston rod 801 pushes the connecting piston arm 803 and drives the valve plate assembly 12 to reset.

[0033] During this process, if the filter element 2 is blocked due to the gap between the filter box 1 and the filter cartridge 5, the waste water in the water inlet pipe 101 can only be discharged outward through the cleaning pipe 103, which causes the detection seat 14 to continue to press downward, Figure 6 It can be seen that when the sealing ring frame 15 moves downward, the regulating pipe 11 can be sealed synchronously. At this time, the inner cavity of the sewage pipe 3 will not transport the medium to the regulating piston cylinder 8 through the regulating pipe 11. Afterwards, as the reset piston rod 801 is pushed by the elastic force, there is a tendency to reset the valve plate assembly 12. Figure 1 、 Figure 5 and Figure 7 It can be seen that the end of the reset piston rod 801 is fixedly mounted with an alarm bell 9 located outside the cleaning drain pipe 103. Correspondingly, a protrusion 601 is fixedly mounted on the outside of the belt 600. When the reset piston rod 801 is extended, the alarm bell 9 is relatively far away from the protrusion 601. When the reset piston rod 801 is retracted, the alarm bell 9 moves closer to the protrusion 601. As the protrusion 601 rotates with the belt 600, it can strike the alarm bell 9, causing the alarm bell 9 to sound. Since the wastewater in the water inlet pipe 101 cannot be discharged normally from the drain pipe 102 at this time, the sound of the alarm bell 9 can alert technicians to check and maintain the sealing of the filter box 1 and the filter cartridge 5.

[0034] Example 3 is a supplement to Example 2. Please refer to Figure 5 and Figure 6 It can be seen that a detection component 16 for detecting the position of the sealing ring frame 15 is fixedly installed at the bottom of the sewage storage pipe 3, and an electromagnetic valve 7 is electrically connected to it. The electromagnetic valve 7 can make the wastewater in the cleaning pipe 103 flow out to the cleaning connecting pipe 701 and the sewage output pipe 702 respectively. Under normal circumstances, when the sealing ring frame 15 does not contact the detection component 16, the electromagnetic valve 7 is in a power-off state, the cleaning connecting pipe 701 and the cleaning pipe 103 are connected, and the cleaning connecting pipe 701 can discharge the blocked particles in the filter cartridge 5 to the vicinity of the water pump inlet. When the blocking ring frame 15 contacts the detection component 16, causing the detection component 16 to start the solenoid valve 7, the cleaning drain pipe 103 and the sewage output pipe 702 are connected. At this time, the sewage output pipe 702 can discharge the wastewater in the cleaning drain pipe 103 into the sewage pool. The reason is that when the blocking ring frame 15 descends, the impurity particles accumulated in the sewage pipe 3 can be discharged outward from the cleaning drain pipe 103. By controlling the solenoid valve 7, the filtered impurity particles can be output outward.
