DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a filtering device for milking equipment, comprising a filtering device body, the filtering device body comprising a filtering tank 1, a filter pressure assembly 2, a filter suction assembly 3 and a positioning mechanism 4, a top plate 5 is welded on the top of the filtering tank 1, an air pump 14 is placed on the surface of the top plate 5, one end of the air pump 14 is connected to an air supply pipe 37, and the air pump 14 is connected to the filter suction assembly 3 part through the air supply pipe 37, the filter suction assembly 3 is welded to the side of the filtering tank 1, and a reduction gear box 1 is screwed on the surface of the filtering tank 1 5. A filter press assembly 2 is inserted into the interior of the reduction gear box 15. A lifting rod 31 is welded to the top of the filter press assembly 2. A filter press plate 7 is welded to the bottom of the lifting rod 31. A positioning mechanism 4 is installed at the bottom of the inner side of the filter tank 1. The filter press plate 7 is used to press on the surface of the positioning mechanism 4 after moving down. A suction tank 6 is installed in the middle of the suction filter assembly 3, and a gear 25 is integrally formed at the end of the suction filter assembly 3. An injection pipe 9 is connected to the side of the filter tank 1. The injection pipe 9 is used to communicate with the pipe part of the milking equipment. The filtering device is used to filter the milk squeezed out by the milking equipment, and promote the filtering efficiency through the two schemes of pressure filtration and suction filtration.

[0029] When the present invention is used, the milk squeezed out from the milking equipment is transported to the inside of the filter tank 1 along the injection pipe 9, and then the external filter press assembly 2 can be started. After the filter press assembly 2 is running, the internal filter press plate 7 can be driven to move downward until it contacts the top of the milk and applies downward pressure. At this time, pressure can be provided from the inside to promote the milk to be filtered and discharged outward along the bottom filter membrane 11. At the same time, with the help of the transmission structure at the bottom of the filter press assembly 2, the operation of the suction filter assembly 3 is controlled, and then with the help of the suction effect of the suction filter assembly 3 itself, the milk inside the filter tank 1 is sucked out from the surface of the filter membrane 11 until it flows into the inside of the suction tank 6, and the filtered milk sucked out each time can be discharged through the discharge pipe 35 at the bottom. A positioning mechanism 4 is arranged inside the filter tank 1. In cooperation with the positioning mechanism 4, after each filtration of the milk, the inner side of the filter membrane 11 can be scraped and cleaned with the help of the lifting movement of the positioning mechanism 4.

[0030] In this embodiment, the side of the filter tank 1 is provided with a first filter port 10, an air blowing port 12 and a slag discharge port 13, a filter membrane 11 is laid inside the first filter port 10, the air blowing port 12 is provided at the bottom of the first filter port 10, and the air blowing port 12 and the slag discharge port 13 are on the same horizontal plane. The first filter port 10, the air blowing port 12 and the slag discharge port 13 are all in an arc-shaped structure as a whole, the bottom of the filter tank 1 is in a closed state, and the ends of the air blowing port 12 and the slag discharge port 13 are separated from each other.

[0031] Specifically, the injection pipe 9 is arranged above the surface of the filter tank 1. Therefore, in the initial state, after the filter press assembly 2 is operated to control the filter press plate 7 to move up, the injection pipe 9 can be automatically opened. At this time, the external milk is transported from the injection pipe 9 to the inside of the filter tank 1 and can directly fall into the space between the positioning mechanism 4 and the filter press plate 7 for accumulation. Subsequently, after the filter press assembly 2 drives the filter press plate 7 to move down, a downward extrusion force can be applied to the batch of filter tanks 1 to achieve the effect of filtration, and the milk is discharged from the first filter port 10 at the bottom through the filter membrane 11. When cleaning is performed subsequently, the high-pressure airflow provided by the air pump 14 at the top enters and exits the interior from the blowing port 12, and then the bottom of the filter press plate 7 which is aligned with the blowing port is blown, so that the milk with residues and impurities at the bottom of the filter press plate 7 can be discharged from the residue discharge port 13, and the impurities scraped off the filter membrane 11 are also blown out.

[0032] In this embodiment, the filter press assembly 2 includes a motor 22, a screw rod 23 and a filter press plate 7. The output end of the motor 22 is plugged with a screw rod 23, and the surface of the screw rod 23 is sleeved with a lifting bracket 30. The top edge of the filter press plate 7 is integrally formed with a first cover plate 20. The bottom of the reduction gear box 15 is plugged with a linkage shaft 24, and the bottom end of the linkage shaft 24 is keyed with a gear 25. The screw rod 23 passes through the interior of the reduction gear box 15, and the screw rod 23 is transmission-connected with the linkage shaft 24 through the gear set built into the reduction gear box 15. A lifting rod 31 is welded on the top of the filter press plate 7, and the top end of the lifting rod 31 is integrally formed with the bottom of the lifting bracket 30. The outer shell of the motor 22 is screwed to the bottom of the reduction gear box 15. The surface of the filter press plate 7 is also welded with a third cover plate 32. The first cover plate 20 is used to cover the surface of the filter membrane 11, and the third cover plate 32 is used to cover the outlet end of the injection pipe 9. A downward squeezing force is applied to the milk from the inner top through the filter press assembly 2, and suction is also performed from the outer side. The inner and outer sides cooperate with each other to effectively improve the internal filtering efficiency of the milk. The above-mentioned inner and outer auxiliary filtering processes can be completed by only a single power device, which reduces the equipment cost and further improves the filtering efficiency.

[0033] Specifically, after starting the motor 22, the motor 22 drives the screw rod 23 to rotate, and the screw rod 23 passes through the threaded sleeve at the end of the lifting bracket 30, thereby driving the lifting bracket 30 and the lifting rod 31 to move vertically. The filter press plate 7 at the end can apply downward pressure to the milk flowing into the filter tank 1 during the lifting movement, and with the help of this pressure, the milk can be accelerated to be discharged from the surface of the filter membrane 11 to the first filter port 10 on the outside. A third covering plate 32 is provided on one side of the top of the filter press plate 7. Therefore, after the filter press plate 7 moves to the top of the injection pipe 9, the milk transported by the milking equipment can be injected into the interior of the filter tank 1 from the injection pipe 9. When the filter press plate 7 moves to the bottom of the injection pipe 9 and starts to squeeze the milk, the injection pipe 9 can be blocked to prevent the milk from continuing to flow into the top of the filter press plate 7.

[0034] In this embodiment, the suction filter assembly 3 includes a suction tank 6, a guide channel 19 and a suction filter channel 18. The suction filter channel 18 is provided with a second filter port 16 and a cleaning channel 17, and the rear ends of the second filter port 16 and the cleaning channel 17 are both connected to the interior of the guide channel 19. The top of the guide channel 19 is connected to an air supply pipe 37, and a one-way valve 38 is installed at the bottom of the air supply pipe 37. The second filter port 16 is connected to the first filter port 10, and the cleaning channel 17 is connected to the air blowing port 12. A piston plate 29 is installed inside the suction tank 6, and a piston rod 28 is inserted on one side of the piston plate 29. A transmission rod 27 is welded to the end of the piston rod 28, and a rack 26 is welded to the end of the transmission rod 27. The rack 26 is meshed with the gear 25. The bottom of the suction tank 6 is connected to a discharge pipe 35, and a solenoid valve 36 is installed on the surface of the discharge pipe 35. By means of the double-layer channel structure in the suction filter assembly 3 and in cooperation with the positioning mechanism 4 on the inner side, the channel at the bottom for cleaning can be automatically blocked during the process of pressure filtration and suction filtration, thereby ensuring that the milk can be filtered smoothly. When cleaning, the collected residues can be centrally processed by cooperating with the downward movement of the positioning mechanism 4, and the filtering channel part can be blocked, so that the two processes of cleaning and filtering are automatically switched without interfering with each other.

[0035] Specifically, after starting the motor 22, the linkage shaft 24 at the bottom of the other side will be driven to rotate through the reduction gear box 15. The linkage shaft 24 can control the translational movement of the transmission rod 27 through the gear 25 at the bottom and the rack 26. After the translation of the transmission rod 27, the piston rod 28 and the piston plate 29 are driven to translate inside the suction tank 6, so that the suction treatment can be performed inside the suction tank 6. During the suction process, the milk inside the filter tank 1 will pass through the filter membrane 11 from the outside and enter the first filter port 10 and the second filter port 16 in turn, flow into the inside of the guide channel 19, and then flow into the inside of the suction tank 6 for storage. After completing a single filtering and suctioning, the solenoid valve 36 at the bottom is opened to discharge the milk inside the suction tank 6 from the discharge pipe 35.

[0036] In this embodiment, the positioning mechanism 4 includes a positioning plate 8 and a second covering plate 21, the second covering plate 21 is welded to one side of the bottom of the positioning plate 8, a protrusion 33 is inserted on the surface of the positioning plate 8, and a spring rod 34 is welded to the bottom of the positioning plate 8. The bottom of the spring rod 34 is inserted into the bottom end of the inner wall of the filter tank 1, and the second covering plate 21 is used to cover the inner side of the air port 12. The positioning plate 8 fits with the bottom surface of the filter plate 7 through the protrusion 33 on the surface. After each filtration is completed, self-cleaning treatment can be performed, which simplifies the difficulty of later cleaning, ensures that the filtration equipment always maintains high efficiency, and can quickly and automatically discharge the collected residue after completing the cleaning of the filter membrane 11, with a higher degree of automation.

[0037] Specifically, during the pressing process, the spring rod 34 supports the positioning plate 8 so that the second covering plate 21 at the bottom blocks the inner side of the blowing port 12, so that the squeezed milk will not pass through the cleaning channel 17 and flow back to the interior of the filter tank 1 from the blowing port 12. After the pressing is completed, the bottom edge of the filter press plate 7 scrapes over the surface of the filter membrane 11 to scrape off the impurities adhering to the filter membrane 11, and as the filter press plate 7 continues to move downward, it is finally pressed on the protrusion 33. At this time, the positioning plate 8 can be moved downward and covered on the surface of the filter membrane 11 with the help of the first covering plate 20. In this state, the solenoid valve 36 is closed, the air pump 14 is started, and the high-pressure airflow is injected along the air supply pipe 37 and the guide channel 19, which can be blown into the blowing port 12 from the cleaning channel 17, and then the milk containing impurities is blown out from the slag discharge port 13 from the gap between the filter press plate 7 and the positioning plate 8, thereby achieving the purpose of cleaning.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
