Description

Technical Field

[0001] This invention relates to the field of shellfish cleaning, drying and sorting technology, specifically to a shellfish cleaning, drying and sorting device. Background Technology

[0002] Shellfish recovered from the sea often contain large amounts of solid impurities such as sea mud and sand, along with a large amount of turbid seawater. Without preliminary processing such as washing, drying, and sorting, the recovered shellfish will be difficult to process further. Traditionally, shellfish washing requires significant manpower, resources, and water waste, and the lack of secondary treatment or recycling of the processed impurities and wastewater easily leads to serious environmental pollution. Currently, although many devices have automated shellfish washing and sorting, they still do not treat the processed impurities and wastewater, and the sorting methods are too rigid, failing to effectively separate shellfish of different sizes.

[0003] CN214207019U discloses a shellfish sorting and cleaning device. The device has a support frame at the bottom of the sorting table, and a water collection tank at the bottom of the support frame. A driven roller is located between the front and rear sides of one end of the support frame, and a conveyor belt is mounted on the driven roller. The other end of the conveyor belt is mounted on a driving roller, which is rotatably connected to a receiving frame. The conveyor belt has an inclined structure, and its upper end is located on the receiving frame. A cleaning water pipe is located on the other side of the support frame. The cleaning water pipe has a U-shaped structure, and both ends are fixedly connected to the support frame. Multiple water outlet pipes connect the two sides of the cleaning water pipe. Multiple cleaning nozzles are evenly spaced along the length of the bottom of the water outlet pipe. A fixed bracket is located on the top of the receiving tank, and the driving roller is rotatably connected to the fixed bracket. A conveyor motor is also located on one side of the fixed bracket. Although the device can automate the cleaning and sorting of shellfish, it only collects the treated wastewater without further treatment. Moreover, the device's sorting of shellfish is too simplistic and cannot effectively sort shellfish of different sizes. Summary of the Invention

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a shellfish cleaning, drying and sorting device, including: a primary filter box 1, a clean water tank 2, a filter water tank 3, a drying box 4 and a sorting box 5. The primary filter box 1 is provided with a primary filter plate 13, a primary filter tank 17, a primary filter pipe 19 and a first conveyor 18. The primary filter plate 13 is installed above the primary filter tank 17 and connected to the first conveyor 18. The primary filter tank 17 is connected to the primary filter pipe 19. The shellfish after primary filtration are transported to the filter water tank 3 through the first conveyor 18.

[0044] like Figure 1 , Figure 9 and Figure 10As shown, the water filter box 3 is equipped with a water filter plate 31, a water filter tank 33, a water filter pipe 34, and a second conveyor 35. The water filter plate 31 is installed above the water filter tank 33 and connected to the second conveyor 35. The water filter tank 33 is connected to the water filter pipe 34. The filtered shellfish are transported to the drying box 4 through the second conveyor 35.

[0045] like Figure 1 , Figure 7 and Figure 8 As shown, the water purification tank 2 is equipped with a water purification device 21 and a water tank 22. The inlet of the water purification device 21 is connected to the primary filter pipe 19 and the filter pipe 34, and the outlet of the water purification device 21 is connected to the water tank 22.

[0046] like Figure 1 and Figure 9 As shown, the drying box 4 is equipped with a drying device 42 and a third conveyor 45. The drying device 42 is connected to the third conveyor 45, and the dried shellfish are transported to the sorting box 5 through the third conveyor 45.

[0047] like Figure 1 and Figure 13 As shown, the sorting box 5 is equipped with a primary sorting frame 52 and several sorting boxes 51. The sorting boxes 51 are installed in a drawer-type manner. The primary sorting frame 52 is installed above the first sorting box. Both the sorting box 51 and the primary sorting frame 52 are equipped with several rollers 511. The sorting boxes 51 are installed in the sorting box 5 according to the size of the gap between the rollers 511 from large to small, and the dried shellfish are sorted by the size of the gap between the rollers 511.

[0048] like Figure 4 and Figure 5 As shown, the primary filter box 1 is also equipped with a directional movable shaft 14, a primary filter plate motor 15, and a first electric pusher plate 16. The primary filter plate 13 is mounted on the directional movable shaft 14, and the primary filter plate motor 15 is connected to the primary filter plate 13. Under the control of the primary filter plate motor 15, the primary filter plate 13 makes a directional reciprocating motion along the directional movable shaft 14. The first electric pusher plate 16 is located on one side of the primary filter plate 13 and pushes the pre-filtered shellfish into the first conveyor 18.

[0049] like Figure 6 As shown, the primary filter plate 13 includes two layers of perforated filter mesh 131, with a perforation in the middle.

[0050] In this embodiment, the primary filter plate 13 in the primary filter box 1 reciprocates along the directional movable axis 14 according to the set parameters. The directional reciprocating motion generates vibration, and the perforated filter screen 131 shreds the large volume of sea mud and sand remaining in the recovered shellfish. The shredded sea mud and sand flow into the primary filter tank 17 along with the recovered seawater, and then enter the purified water tank 2 through the primary filter pipe 19. The shellfish after primary filtration are pushed into the first conveyor 18 by the first electric pusher plate 16 on one side of the primary filter plate 13.

[0051] like Figure 1 As shown, a high-pressure nozzle 181 is provided on the first conveyor 18. The high-pressure nozzle 181 is equipped with a high-pressure nozzle water pipe 182 and a first high-pressure water pump 183. The high-pressure nozzle water pipe 182 is connected to the water tank 22, and the clean water is pumped into the high-pressure nozzle 181 under the action of the first high-pressure water pump 183.

[0052] In this embodiment, high-pressure nozzles 181 are provided on both sides of the first conveyor 18 to spray clean water to clean the shellfish after initial filtration according to the set parameters, and then the shellfish enter the water filter tank 3.

[0053] like Figure 10 As shown, the water filter tank 3 is also equipped with a second electric pusher plate 32, which is located on one side of the water filter plate 31 to push the filtered shellfish into the second conveyor 35.

[0054] In this embodiment, the shellfish entering the filter tank 3 discharge the washed wastewater and fine impurities into the filter tank 33 on the filter plate 31, and then flow into the clean water tank 2 through the filter pipe 34. After being washed, the shellfish are pushed onto the second conveyor 35 by the second electric pusher plate 32 on one side of the filter plate 31 and transported to the drying box 4.

[0055] In addition, in this embodiment, the filter pipe 34 is equipped with a second high-pressure water pump 36, which pumps the filtered water into the water purification device 21 under the action of the second high-pressure water pump 36.

[0056] like Figure 8 As shown, the water purification tank 2 is also equipped with a filter cake outlet 23. The water purification device 21 includes a filter 211 and a filter cake tank 212. The filter 211 is connected to the filter cake tank 212. The filtered filter cake is discharged from the water purification device 21 through the filter cake tank 212 and discharged from the water purification tank 2 through the filter cake outlet 23. The filter cake outlet 23 adopts an openable structure and is opened when the device is running.

[0057] In this embodiment, the pre-filtered seawater, sea mud, and sea sand, as well as the filtered wastewater and fine impurities, enter the clean water tank 2 through the pre-filter pipe 19 and the filter pipe 34. After being filtered by the filter 211 in the water purification device 21, the clean water flows into the water tank 22 and is then transported to the high-pressure nozzle 181 through the high-pressure nozzle water pipe 182 under the action of the first high-pressure water pump 183, thereby saving resources and protecting the environment. The filtered filter cake is discharged through the filter cake tank 212 and the filter cake outlet 23 for recycling. The filter cake outlet 23 should be open when the device is running and can be closed when the device is not running.

[0058] like Figure 10As shown, the drying chamber 4 is also equipped with a steam conduit 43 and a condenser 44. The condenser 44 is installed on the steam conduit 43. One end of the steam conduit 43 is connected to the drying device 42, and the other end is connected to the water filter pipe 34. The drying device 42 includes a heating plate 421 and a spiral channel 422. The heating plate 421 is cylindrical and encloses the spiral channel 422 inside.

[0059] In this embodiment, the cleaned shellfish enter the drying device 42 through the drying box inlet 41 and move along the spiral channel 422. Heating plates 421, arranged around the shellfish, dry them according to set parameters. Due to the heating, the moisture on the shellfish turns into water vapor and is discharged through the steam pipe 43. The vapor is then liquefied into water by the condenser 44. Since the steam pipe 43 is connected to the water filter pipe 34, the liquefied water also flows through the water filter pipe 34 into the clean water tank 2. The dried shellfish are discharged from the spiral channel 422, fall into the third conveyor 45, and are then transported to the sorting box 5 by the third conveyor 45.

[0060] like Figure 13 , Figure 14 and Figure 15 As shown, the sorting box 51 is also equipped with a wall panel 513 and a rotary motor 512. Several fixed shafts 514 are mounted on the wall panel 513. Roller shafts 511 are connected to the fixed shafts 514. The rotary motor 512 is connected to the roller shafts 511 via belts 515, and the roller shafts 511 are also connected to each other via belts. The roller shafts 511 rotate under the control of the rotary motor 512. The bottom part of the sorting box 51 is hollowed out, and the position of the hollowed-out portion corresponds to the distribution position of the roller shafts 511.

[0061] In this embodiment, the initial sorting frame 52 adopts a 12-axis structure, and the sorting boxes 51 are all of uniform size, with a total of five layers. The first four layers use sorting boxes with 14, 16, 18, and 21 axes respectively, while the last layer has no rollers 511 and the bottom is not hollowed out. When the device starts operating, the rollers 511 in the sorting boxes 51 begin to rotate according to the set parameters. After the dried shellfish are sorted on the initial sorting frame 52, the largest shellfish are first selected, and the remaining shellfish fall into the 14-axis sorting box in the first layer. Since the 14-axis rollers are arranged more densely than the 12-axis rollers, another batch of shellfish is sorted out, and the remaining shellfish fall into the sorting box in the next layer to continue the sorting process. In other embodiments, the sorting boxes 51 can be selected according to the size of the shellfish being sorted, and the gap between the rollers 511 in different sorting boxes 51 is set differently.

[0062] In addition, in this embodiment, the primary filter box 1 is also equipped with an operating table 11 and a CNC circuit board 12. The operating table 11 is connected to the CNC circuit board 12, and the operating table 11 sets the operating parameters of the device through the CNC circuit board 12. In this embodiment, the primary filter box 1 is opened, the collected shellfish are poured into the primary filter box 1, and the movement speed of the primary filter plate 13 in the primary filter box 1, the water spraying speed of the high-pressure nozzle 181, the temperature of the heating plate 421 in the drying box 4, the rotation speed of the rollers 511 in each sorting box 51 in the sorting box 5, and the movement speed of each conveyor are set on the operating table 11. Then the device starts to operate.

[0063] The above description is merely a preferred embodiment of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the protection scope of the present invention.
