Description

Technical Field

[0001] The invention belongs to the technical field of dairy product filtration, and in particular relates to a filtration device for processing lily dairy products. Background Art

[0002] Lily dairy products are a type of specialty food that combines lily with traditional dairy products. They have unique flavor and nutritional value. They are made by adding lily extract, lily powder or fresh lily granules to fresh cow's milk or goat's milk, and then undergoing blending, sterilization and other processes. For example, lily-flavored milk has the mellow milky aroma of milk and the sweetness and fragrance of lily, with a rich taste. Lily dairy products need to be filtered during the processing. For example, the patent with patent announcement number CN202605851U proposes an ultra-clean filtration device for liquid milk.

[0003] The centrifugal filter device can quickly separate large particles of impurities in lily dairy products, such as inadequately crushed lily tubers and fiber bundles, by virtue of the strong centrifugal force generated by high-speed rotation, and make them quickly settle to the edge or bottom of the centrifugal container, greatly shortening the impurity separation time and significantly improving production efficiency. Therefore, it is widely used in the lily dairy product filtration process. However, during the filtration process, since lily is rich in fiber, starch, protein and other components, these substances are very easy to accumulate locally on the filter after a long period of filtration. Since it is difficult to determine the approximate location of the filter blockage, the filter can only be fully backwashed with high-pressure water flow to clear the blocked area. However, long-term use of high-pressure water flow for flushing will cause the strong water pressure to destroy the physical structure of the filter, resulting in different pore sizes of the filter, which in turn affects the filtration accuracy of the filter.

[0014] Compared with the existing technology, the advantages of a filtering device for processing lily dairy products are: 1.

Through the provided water spray pipe, water outlet and micro water pump, after the viscosity of the lily dairy products is tested by the detection component, the lily dairy products adhering to the surface of the rotational viscometer can be automatically cleaned to avoid the problem that the remaining lily dairy products on the surface of the rotational viscometer will affect the accuracy of the next test result.

[0028] The operating principle of the present invention is now explained as follows: the lily dairy product is transported to the rotating tube 7 through the injection tube 9 by the external pump assembly, and then the lily dairy product is transported to the grid 101 through the rotating tube 7. When the lily dairy product is transported to the injection tube 9, the PLC controller 3 will control the detection pump 352 to work, and the detection pump 352 will transport the lily dairy product in the injection tube 9 to the detection tank 37. After the detection pump 352 has worked for two seconds, the PLC controller 3 will control the detection pump 352 to stop working, and control the small electric push rod 41 to drive the rotary viscometer 42 to move downward to the set position, so that the detection end of the rotary viscometer 42 extends into the lily dairy product. The viscosity of the lily dairy product is detected in the product (the rotary viscometer 42 is driven by a motor to rotate the rotor in the lily dairy product, so that the lily dairy product generates a shear force. The viscosity of the lily dairy product will hinder the movement of the rotor and generate a resistance proportional to the viscosity), and the detection result is transmitted to the PLC controller 3 (later, after the filtration device is finished working, the micro water pump 45 is used to transport the water flow to the water spray pipe 43 and spray it through the water outlet head 44, and the water outlet head 44 is used to clean the dairy product adhered to the surface of the rotary viscometer 42, and at the same time, the drain valve 39 is opened to allow the cleaned liquid to be transported to the injection pipe 9 and the rotating pipe 7 through the drain pipe 38, and then through the discharge pipe 1 02 and the discharge pipe 5 discharge the filter cartridge 4), after receiving the detection result, the PLC controller 3 will control the filter motor 8 to work (when the rotary viscometer 42 detects that the viscosity of the lily dairy product is high, it means that the fat content inside the lily dairy product is high, and it is necessary to control the filter motor 8 to work at a lower power to avoid excessive power of the filter motor 8 and excessive power and speed of the centrifugal filter device, which will cause the fat globules accumulated in the fat to rupture and free the fat, thereby causing product stratification and oil droplet problems. For example, when the rotary viscometer 42 detects that the viscosity of the lily dairy product is 800-1500mPa・s, the PLC controller 3 will control the filter motor 8 to work at a lower power to avoid excessive power of the filter motor 8 and excessive power and speed of the centrifugal filter device, which will cause the fat globules accumulated in the fat to rupture and release ... The filter motor 8 drives the grid 101 to filter the lily dairy product at a centrifugal speed of about 4000r / pm. When the rotation viscometer 42 detects that the viscosity of the lily dairy product is 1500-3200mPa・s, the PLC controller 3 will control the filter motor 8 to drive the grid 101 to filter the lily dairy product at a centrifugal speed of about 3000r / pm. The filter motor 8 drives the rotating tube 7 to rotate through the gear transmission assembly, and the rotating tube 7 drives the grid 101 to rotate. The grid 101 drives the internal lily dairy product to be centrifugally filtered. The filtered dairy product passes through the filter screen 15 and is discharged from the filter cartridge 4 through the discharge pipe 5 and the first control valve 6. In the process of rotating tube 7 driving grid frame 101 to rotate, under the action of centrifugal force, filter screen 15 and mouth frame 14 will move away from grid frame 101. When mouth frame 14 moves away from grid frame 101, it will drive conductive block 19 to move away from grid frame 101 and towards filter screen 15 through upper sliding plate 16. Conductive block 19 is always in contact with resistor plate 18 during movement. One end of resistor plate 18 close to filter screen 15 is electrically connected to conductive slide rail 53 on the upper side of corresponding arc plate 22. Conductive slide rail 53 on the upper side of corresponding arc plate 22 is electrically connected to PLC controller 3 through conductive slider 52 on the upper side of conductive frame 23. When filter screen 15 is not blocked or mesh size is enlarged, Under the action of the same centrifugal force, multiple filter screens 15 will drive multiple mouth frames 14 to move approximately the same distance away from the grid 101. The PLC controller 3 receives approximately the same current signal strength transmitted by each upper conductive slider 52. When a filter screen 15 is blocked, the permeability of the filter screen 15 will decrease. During the process of the rotating tube 7 driving the grid 101 to rotate and centrifuge, the resistance of dairy products passing through the filter screen 15 will increase. The increased resistance plus the centrifugal force will cause the mouth frame 14 connected to the filter screen 15 to move a farther distance away from the grid 101 during the rotation process. The mouth frame 14 will drive the conductive block 19 to move closer to the filter screen 15 through the upper sliding plate 16. The PLC controller 3 moves farther, thereby shortening the length of the resistor connected to the PLC controller 3 circuit. When the external voltage remains unchanged, the current signal strength transmitted to the PLC controller 3 circuit becomes larger. When the PLC controller 3 detects that the current signal strength of a certain upper conductive slider 52 exceeds the current strength of other upper conductive sliders 52 by five milliamperes, the PLC controller 3 will control the corresponding regulating valve 28 to open for 0.5 seconds through the corresponding lower conductive slider 52 and the conductive slide rail 53 within 0.01 seconds, and control the upper analysis block 25 in the corresponding analysis box 241 to be electrically connected to the external power supply. When the regulating valve 28 is opened, the space inside the corresponding analysis box 241 will be opened, and the corresponding piston block 242 will be opened under the action of the spring force. , will move in the direction close to the vertical pipe 27. When the regulating valve 28 is opened for 0.5 seconds, the piston block 242 will move to two-thirds of the distance in the analysis box 241. When the filter screen 15 on this side is detected to be blocked again during a single filtering operation, the piston block 242 will repeat the above steps and continue to move a corresponding distance in the direction close to the vertical pipe 27. After the second movement of the piston block 242, the two analysis blocks 25 and the two analysis plates 26 will be driven to contact. The upper analysis block 25 is electrically connected to the external power supply, and the upper analysis plate 26 will control the corresponding upper conductive slide rail 53 through the PLC controller 3 to be electrically connected to the external power supply after the filtering device stops filtering, thereby locating the position of the blocked filter screen 15. When the filtering device finishes working, the PLC controller 3 will control the servo motor 30 to work. The servo motor 30 will drive the threaded barrel 292 to rotate through the gear transmission component, drive the lifting tube 31 to move downward through the threaded cooperation, and control the lifting tube 31 to move back and forth up and down on the outside of the filter screen 15. At the same time, the water flow is transported to the lifting tube 31 through the water injection pipe 32 through the external pump assembly, and is transported to the cleaning pipe 33 through the lifting tube 31. At this time, the PLC controller 3 will control all the electric-controlled water spray heads 34 to open, so that the water flow flushes multiple filter screens 15 with a lower water pressure (0.5-1.5MPa). After the flushing work is carried out for one minute, the PLC controller 3 will close the other electric-controlled water spray heads 34, and at this time, the corresponding upper conductive slide rail 53 is electrically connected to the external power supply after the filtering device stops filtering. The corresponding upper conductive slide rail 53 transmits an electrical signal to the PLC controller 3 through the corresponding upper conductive slider 52. After receiving the electrical signal transmitted by the upper conductive slider 52, the PLC controller 3 will control A small number of electrically controlled water spray heads 34 in the area corresponding to the upper conductive slider 52 are turned on. Since the other electrically controlled water spray heads 34 are already closed, when the power of the external pump assembly remains unchanged and a small number of electrically controlled water spray heads 34 are turned on, the water pressure sprayed from the small number of water spray heads will increase (2-3 MPa), so that the blocked position of the filter screen 15 is flushed for one minute using a larger water pressure, so that the blocked foreign matter is discharged from the discharge pipe 102 and the discharge pipe 5. When the flushing work is completed, the PLC controller 3 will control the external pump assembly to stop, so that the flushing work is stopped. Similarly, when the corresponding filter screen 15 is damaged and the permeability increases, referring to the above principle, the lower conductive slide rail 53 at the corresponding position of the damaged filter screen 15 will continue to be energized. When the filtering work is completed, the lower conductive slide rail 53 at the corresponding position contacts the lower conductive slider 52 at the corresponding position, and the lower conductive slider 52 at the corresponding position will control the corresponding indicator light 51 to work through the PLC controller 3, so that the operator can quickly find the damaged filter screen 15 and replace it later. When the impurities on the surface of the filter screen 15 are cleaned, or the damaged filter screen 15 is replaced, the operator controls all the regulating valves 28 to open through the PLC controller 3, and controls the filter motor 8 to drive the grid frame 101 to rotate at a centrifugal speed of 7000r / pm. When the grid frame 101 drives the internal analysis box 241 to rotate at a centrifugal speed of 7000r / pm, the centrifugal force exerted on the piston block 242 inside the analysis box 241 is 500N, so that the centrifugal force exerted on the piston block 242 exceeds the elastic force of 400N of the spring between the piston block 242 and the analysis box 241. The piston block 242 will drive the two analysis blocks 25 to move together in the direction away from the analysis plate 26. After the filter motor 8 drives the grid frame 101 to rotate for ten seconds, the PLC controller 3 will control all the regulating valves 28 to close, and control the grid frame 101 to stop rotating. At this time, the air inside the analysis box 241 is in a closed state, and the piston block 242 will stop moving under the push of air pressure, thereby restoring the moved piston block 242 to its initial state.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
