Technical Field

[0001] The utility model relates to the technical field of pipeline filters, in particular to a food processing pipeline filter which is easy to clean. Background Art

[0002] Food processing pipeline filters are an indispensable and important equipment in the food processing industry. During the food processing process, liquid raw materials, semi-finished products and finished products are often mixed with impurities, particulate matter, microorganisms and other pollutants when they are transmitted in the pipeline, affecting the quality and safety of food. Food processing pipeline filters use precise filter media such as stainless steel mesh and filter elements to effectively intercept and remove these pollutants to ensure the purity of food fluids.

[0003] In actual use, it is necessary to unscrew the threaded cap on the filter cartridge and then remove the filter element for cleaning. Cleaning is quite laborious and requires stopping the conveying of liquid raw materials before cleaning, which is inconvenient. Therefore, we propose a food processing pipeline filter that is easy to clean. Utility Model Content

[0023] See also Figure 1-2 The utility model provides a technical solution: a food processing pipeline filter that is easy to clean, comprising a filter bin 1, an inlet pipe 2 and an outlet pipe 3. The interior of the filter bin 1 is cylindrical, and the inlet pipe 2 and the outlet pipe 3 are connected to the side surfaces on both sides of the filter bin 1 and are aligned with each other. At the same time, on both sides of the surface of the filter bin 1 on the sides of the inlet pipe 2 and the outflow pipe 3, there are also sewage pipes 5 and flushing pipes 4 that are symmetrical to the outflow pipe 3 and the outflow pipe 3. The sewage pipe 5 and the flushing pipe 4 are aligned with each other and connected to the interior of the filter bin 1.

[0024] Solenoid valves 6 are installed on the inlet pipe 2, the outlet pipe 3, the flushing pipe 4 and the sewage pipe 5. The solenoid valves 6 are respectively connected to the inside of the inlet pipe 2, the outflow pipe 3, the flushing pipe 4 and the sewage pipe 5, so as to realize the control of the open or closed state of the solenoid valves 6.

[0025] A rotating plate 8 is rotatably installed inside the filter chamber 1 through a rotating rod 81, and the rotating rod 81 is rotatably connected to the inside of the filter chamber 1 through a waterproof bearing. A servo motor 7 is installed on the outer surface of the filter chamber 1 at the end of the rotating rod 81. The servo motor 7 is transmission-connected to the rotating rod 81. When in use, the servo motor 7 can drive the rotating rod 81 to rotate the rotating plate 8 to a required angle and lock it.

[0026] Two guide cylinders 82 are fixedly passed through the surface of the rotating plate 8 in the horizontal direction. The two guide cylinders 82 are respectively connected between the inflow pipe 2 and the outflow pipe 3, the flushing pipe 4 and the sewage pipe 5, and the guide cylinders 82 on the side of the outflow pipe 3 and the flushing pipe 4 are fixed with filter screens 821. When in use, the inflow pipe 2 and the outflow pipe 3 are connected to the conveying pipe of the liquid food raw material through flanges, and the liquid raw material can flow in from the inflow pipe 2 and flow out from the outflow pipe 3. The flushing pipe 4 and the sewage pipe 5 are respectively connected to the clean water supply pipe and the drainage pipe through flanges, so that the liquid raw material can flow in from the left side, pass through the inside of the guide cylinder 82, and be filtered by the filter screen 821 on the left side thereof. Then it is discharged from the outflow pipe 3 on the left. When the filter 821 needs to be cleaned, all the solenoid valves 6 are closed first, and then the servo motor 7 is controlled to drive the rotating plate 8 and the guide cylinder 82 to rotate 180 degrees, so that the positions of the two guide cylinders 82 are swapped, and then the filter 821 and the guide cylinder 82 that need to be cleaned can be rotated to the bottom and connected between the flushing pipe 4 and the sewage pipe 5, while the clean filter 821 and the guide cylinder 82 are rotated to the top and connected between the inflow pipe 2 and the outflow pipe 3. Then the solenoid valve 6 is opened, and clean water flows from the left to the right to flush the filter 821. Finally, the sewage is discharged from the sewage pipe 5 on the right, and the filter 821 above can continue to achieve the purpose of filtering the liquid raw materials.

[0027] In order to prevent impurities left over from filtration from leaking out during rotation, the device can be installed vertically, with the inlet pipe 2 and the drain pipe 5 facing upward, and the outlet pipe 3 and the flushing pipe 4 facing downward. At the same time, rubber bosses 9 are fixed inside the filter bin 1 at the ends of the inlet pipe 2, the outflow pipe 3, the flushing pipe 4 and the drain pipe 5. The outer edge of the rubber boss 9 is provided with an inclined edge, and the inlet pipe 2, the outflow pipe 3, the flushing pipe 4 and the drain pipe 5 are connected to the inner circle of the rubber boss 9, so that when the guide cylinder 82 rotates so that the end is close to the inlet pipe 2, the outflow pipe 3, the flushing pipe 4 or the drain pipe 5, it can first be guided by the inclined edge, and then the end of the guide cylinder 82 can be smoothly pressed against the surface of the rubber boss 9, thereby maintaining a sealed connection with the inlet pipe 2, the outflow pipe 3, the flushing pipe 4 or the drain pipe 5.

[0028] During use, the inflow pipe 2 and the outflow pipe 3 are connected to the conveying pipe of the liquid food raw material through flanges, so that the liquid raw material can flow in from the inflow pipe 2 and flow out from the outflow pipe 3. The flushing pipe 4 and the sewage pipe 5 are respectively connected to the clean water supply pipe and the drainage pipe through flanges, and the solenoid valve 6 and the servo motor 7 are connected to the industrial control equipment. When filtering the liquid food raw materials, the solenoid valve 6 on the inflow pipe 2 and the outflow pipe 3 is opened, and the liquid raw material flows in from the right inflow pipe 2, passes through the inside of the guide cylinder 82, and is filtered by the filter screen 821 to leave impurities, and then flows out from the left outflow pipe 3. When the filter screen 821 needs to be cleaned after being used for a period of time, all the solenoid valves 6 can be closed first, and the servo motor 7 can be controlled to drive the rotating plate 8 to rotate 180 degrees, drive the two guide cylinders 82 to rotate and exchange positions with each other, so that the guide cylinder 82 containing impurities on the right side of the filter screen 821 is rotated to the bottom and connected between the flushing pipe 4 and the sewage pipe 5. , and the conduit originally connected between the flushing pipe 4 and the sewage pipe 5 is rotated to the upper side to connect between the inflow pipe 2 and the outflow pipe 3. After all the solenoid valves 6 are opened, the liquid raw material can flow in from the inflow pipe 2 and be filtered by the filter screen 821 in the upper guide cylinder 82 and discharged from the outflow pipe 3. At the same time, clean water flows in from the flushing pipe 4, and flushes the filter screen 821 in the lower guide cylinder 82 in the opposite direction of the filtration, and discharges the sewage from the sewage pipe 5. After flushing for a period of time, the solenoid valves 6 of the flushing pipe 4 and the sewage pipe 5 are closed, and the above operation can be repeated, alternating between using the filter screen 821 in different guide cylinders 82 for filtering, and flushing and cleaning the other filter screen 821. In order to prevent the impurities filtered and retained in the guide cylinder 82 from leaking out when the guide cylinder 82 is rotated to change its position, the device can be installed vertically, with the inflow pipe 2 and the sewage pipe 5 facing upward, and the outflow pipe 3 and the flushing pipe 4 facing downward.
