Description

Technical Field

[0002] In the wet processing of coffee, a large amount of clean water is needed to treat the coffee beans, such as washing away impurities attached to the surface of the coffee beans and peeling the peels by hydraulic pressure. However, wet processing causes waste of water resources and water treatment problems.

[0003] When existing cleaning equipment filters coffee bean processing water, the filter cylinder is easily blocked due to the large amount of peels, mucus and impurities mixed in the processing water. Some equipment can realize reverse flushing of the filter cylinder, and the reverse flow of cleaning water flows from the outside of the filter cylinder to the inside. Although it has a certain flushing effect, the flushing water is influx-type, the flushing water pressure is not high, and the flushing effect is poor.

[0043] The reversing assembly 2 includes a first rotating plate 21, which is rotatably connected to the support block 12. A first filter box 22 and a second filter box 23 are fixedly mounted on the first rotating plate 21. The first filter box 22 and the second filter box 23 are vertically arranged and not connected. Four through holes 24 distributed in an array are opened on the first rotating plate 21. The two through holes 24 on opposite sides are in the same group. The first filter box 22 and the second filter box 23 are connected to the water storage tank 13 or the drainage hole 14 through the through holes 24 of the corresponding groups. For example, when the first filter box 22 is connected to the water storage tank 13 through a group of through holes 24, the second filter box 23 is connected to the drainage hole 14 through another group of through holes 24. After the first rotating plate 21 rotates 90 degrees, the positions of the first filter box 22 and the second filter box 23 are switched. At this time, the first filter box 22 is connected to the drainage hole 14 through the through holes 24, and the second filter box 23 is connected to the water storage tank 13 through the through holes 24, thereby realizing the switching of the filter boxes in working and non-working.

[0044] A plurality of sleeves 25 are rotatably connected to the first rotating plate 21, and the plurality of sleeves 25 correspond to the plurality of through holes 24 one by one and their axes are colinear. The reversing assembly 2 also includes a first fixing ring 26 and a second fixing ring 27. The second fixing ring 27 is located directly above the first fixing ring 26. The first fixing ring 26 and the second fixing ring 27 are both rotatably matched with the fixing box 11. First flow exchange holes 28 and second flow exchange holes 29 are provided on both sides of the first filter box 22 and the second filter box 23. The plurality of first flow exchange holes 28 and the plurality of second flow exchange holes 29 are distributed in an array. The first flow exchange holes 28 penetrate the first fixing ring 26, and the second flow exchange holes 29 penetrate the second fixing ring 27. The first flow exchange holes 28 are at the same height as the inlet of the outlet pipe 16, and the second flow exchange holes 29 are at the same height as the outlet of the return pipe 17.

[0045] When a first flow exchange hole 28 on the first filter box 22 is connected to the water outlet pipe 16, the other first flow exchange holes 28 are blocked by the inner wall of the fixed box 11 and are in a closed state. At this time, a second flow exchange hole 29 on the second filter box 23 is connected to the return pipe 17, and the other second flow exchange holes 29 are blocked by the inner wall of the fixed box 11 and are in a closed state.

[0046] Reference Figures 5 to 10 The first filter box 22 and the second filter box 23 are both equipped with a cleaning assembly 3, and the cleaning assembly 3 includes two groups of support boxes 31. The tops of the first filter box 22 and the second filter box 23 are both equipped with two groups of support boxes 31. The two groups of support boxes 31 are connected to each other through the second connecting pipe 32. The support boxes 31 between the first filter box 22 and the second filter box 23 are not connected. An impeller 33 is rotatably connected in each support box 31, and the axis of the impeller 33 is colinear with the axis extension line of the corresponding sleeve 25. A third connecting pipe 34 is connected and installed on the support box 31, and a plurality of nozzles 35 are connected and installed on the third connecting pipe 34. The spraying direction of the nozzle 35 is perpendicular to the surface of the filter screen cylinder 4. There is a certain deflection angle between the connection between the third connecting pipe 34 and the support box 31 and the connection between the second connecting pipe 32 and the support box 31, so as to ensure that the water flow between the third connecting pipe 34 and the second connecting pipe 32 can drive the impeller 33 to rotate. The third connecting pipe 34 is connected to the corresponding second exchange hole 29, and a plurality of guide rods 36 are fixedly installed on the top of the impeller 33.

[0047] The two ends of the filter screen cylinder 4 are open, the filter screen cylinder 4 fits through the sleeve 25, the top of the filter screen cylinder 4 is threadedly matched with the impeller 33, the bottom of the filter screen cylinder 4 is fixed to the sleeve 25 by bolts or limit pins, and the filter screen cylinder 4 is in the first filter box 22 or the second filter box 23; the filtered treated water enters the support box 31 from the return pipe 17 through the second exchange hole 29 and the third connecting pipe 34 to drive the impeller 33 to rotate, and enters another support box 31 from the second connecting pipe 32 to drive the impeller 33 to rotate and flow into the corresponding third connecting pipe 34, the rotation of the impeller 33 drives the filter screen cylinder 4 to rotate, and at the same time the treated water in the third connecting pipe 34 is sprayed from the nozzle 35 to the surface of the filter screen cylinder 4, thereby realizing the reverse flushing of the filter screen cylinder 4, and the flushing effect is good.

[0048] In order to further improve the flushing effect of the nozzle 35 and the rotation effect of the filter screen drum 4, a booster pump is installed on the return pipe 17 to increase the pressure of the returned treated water, thereby increasing the water flow rate.

[0049] Reference Figure 1 , Figure 2 , Fig. 9 , Figures 11 to 13The cleaner also includes a transmission assembly 5, which includes a rotating box 51 and a second rotating plate 52. The rotating box 51 is mounted on the fixed box 11 and is rotatably connected to the fixed box 11. The second rotating plate 52 is located at the top of the fixed box 11 and is rotatably connected to the fixed box 11. The support box 31 is fixedly connected to the second rotating plate 52. A top plate 53 is slidably connected to the rotating box 51, and a plurality of buoyancy columns 54 are fixedly installed on the top plate 53. A plurality of first elastic members 55 are arranged in the rotating box 51. One end of the first elastic member 55 is fixedly connected to the buoyancy column 54, and the other end is fixedly connected to the rotating box 51. A guide pipe 56 that slidably cooperates with the buoyancy column 54 is fixedly installed on the second rotating plate 52. The bottom of the guide pipe 56 is rotatably cooperated with the impeller 33 and is connected to the top of the filter screen cylinder 4. When the filter screen cylinder 4 is blocked, excess water to be treated enters the guide pipe 56 from the top of the filter screen cylinder 4 to push the buoyancy column 54 up.

[0050] The transmission assembly 5 also includes a plurality of push rods 57 and a plurality of arc blocks 58. The push rods 57 are fixedly mounted on the bottom of the top plate 53, and the arc blocks 58 are fixedly mounted on the top of the fixed box 11. The plurality of push rods 57 and the plurality of arc blocks 58 are distributed in an array, and the number of the push rods 57 and the arc blocks 58 corresponds to the number of the filter screen cylinders 4. The top of the arc block 58 is an inclined surface 59. A plurality of inclined plates 510 distributed in an array about the rotating axis of the rotating box 51 are fixedly mounted on the outer side of the rotating box 51, and the inclination direction of the inclined plate 510 is opposite to the inclination direction of the inclined surface 59. A ratchet 511 is installed at the rotating connection between the rotating box 51 and the fixed box 11, so as to control the rotating box 51 to rotate only in one direction on the fixed box 11. Along the rotation direction of the rotating box 51, the height of the inclined surface 59 gradually decreases.

[0051] The cleaner also includes a plurality of electromagnets 6 and a plurality of armatures 7. The electromagnets 6 are fixedly mounted below the guide tube 56. The armatures 7 are plugged into the guide rods 36. The distance between the guide rods 36 and the guide tubes 56 is less than the height of the armatures 7 to prevent the armatures 7 from being separated from the guide rods 36. The armatures 7 are located directly below the electromagnets 6. When the filter screen cartridge 4 needs to be replaced, the blocking plate 110 is opened, and the stop pin or bolt between the filter screen cartridge 4 and the sleeve 25 is removed. The electromagnets 6 are energized, and the armatures 7 are moved upward and fixed to the electromagnets 6 under the action of the electromagnetic force, thereby fixing the impeller 33 and the guide tube 56. By rotating the bottom of the filter screen cartridge 4 from the sewage tank 19, the filter screen cartridge 4 is separated from the impeller 33 and drawn out from the sewage tank 19. The new filter screen cartridge 4 can be screwed and locked on the impeller 33 again, thereby realizing the replacement process and reducing the difficulty of replacement.

[0052] The cleaner also includes a push-up assembly 8, which includes an energy storage box 81. The energy storage box 81 is located below the inclined plate 510. The bottom of the energy storage box 81 is connected to the water storage tank 13. A push rod 82 is slidably connected to the energy storage box 81. The push rod 82 passes through the energy storage box 81. A connecting plate 83 is fixedly installed at the bottom of the push rod 82. The connecting plate 83 slides with the energy storage box 81. A second elastic member 84 is arranged in the energy storage box 81. One end of the second elastic member 84 is fixedly connected to the connecting plate 83, and the other end is fixedly installed with a floating plate 85. The floating plate 85 slides with the energy storage box 81. The top of the push rod 82 is rotatably connected to a roller 86.

[0053] When the working filter screen cylinder 4 is clogged, the water pressure in the water storage tank 13 increases, and the water enters the energy storage box 81 to push the floating plate 85 upward to compress the second elastic member 84 to store energy, providing power for the subsequent rotation of the transmission assembly 5. In order to further improve the energy storage effect, a pump body is installed on the first connecting pipe 15, and a pressure gauge is installed at the outlet of the pump body for pump pressure detection. The pump body continuously delivers the water to be treated into the water storage tank 13.

[0054] Reference Figure 2 and Fig.11 The cleaner also includes a photoelectric sensor 9, which includes a receiver 91 and a plurality of transmitters 92. The receiver 91 is fixedly mounted on the rotating box 51, and the transmitter 92 is fixedly mounted on the top plate 53. A transmitter 92 is distributed above each top rod 57, and the plurality of transmitters 92 are sequentially arranged in a clockwise or counterclockwise order, namely, 1, 2, 3 and 4. When the receiver 91 detects that the transmitter 92 has swapped positions (which can be distinguished by emitting different wavelengths), that is, the number of the transmitter 92 changes from an even number to an odd number or from an odd number to an even number, the reversing valve 18 is reversed, and the treated water in the outlet pipe 16 is sent into the return pipe 17, and the filter screen cylinder 4 after the switching position is backwashed. After the set time, the reversing valve 18 automatically switches back, and the treated water continues to be transported from the outlet pipe 16. The photoelectric sensor 9 of this embodiment does not need to be in a long-term open monitoring state. It is controlled to open by the pump pressure monitored by the pressure gauge. When the pump pressure reaches the set value, the photoelectric sensor 9 is turned on until it receives a signal from a group of transmitters 92 and obtains the corresponding number, and compares it with the number of the transmitter 92 stored last time. When the two numbers are different, the reversing valve 18 is opened, otherwise it is not opened.

[0055] Working principle: The pump body continuously and stably delivers the circulating water used in coffee processing from the first connecting pipe 15 into the water storage tank 13 and then into the filter screen cylinder 4 connected to the water storage tank 13. After being filtered by the filter screen cylinder 4, the circulating water enters the corresponding filter box (here, for the convenience of subsequent description, it is assumed to enter the first filter box 22). The circulating water in the first filter box 22 flows into the water outlet pipe 16 through the first flow exchange hole 28 to realize the filtration process.

[0056] As the impurities in the circulating water gradually increase, the mesh of the filter screen cartridge 4 is gradually blocked, the filtering efficiency is reduced, and the water pressure in the filter screen cartridge 4 gradually increases. The circulating water in the water storage tank 13 enters the energy storage box 81 to push the floating plate 85 up, while the push rod 82 cannot rise due to the action of the inclined plate 510, causing the second elastic member 84 to be continuously compressed. At the same time, the circulating water in the filter screen cartridge 4 enters the guide tube 56 from the top to push the buoyancy column 54, the top plate 53 and the top rod 57 to rise, and the first elastic member 55 is gradually compressed.

[0057] When the pump pressure reaches the first set pressure threshold, the pump body continues to transport circulating water to keep the pump pressure stable, and the bottom of the push rod 57 rises to above the arc block 58. At this time, the rotation limit of the rotating box 51 is released, the photoelectric sensor 9 is turned on, and the push rod 82 rises under the action of water pressure and the elastic force of the second elastic member 84, thereby pushing the inclined plate 510 to drive the rotating box 51, the top plate 53, the second rotating plate 52, the push rod 57, the support box 31 and the reversing assembly 2 to rotate. The push rod 57 rotates to above the inclined surface 59, and the filter screen cartridge 4 in the first filter box 22 rotates from the water storage tank 13 to communicate with the drain hole 14 and relieves the pressure on the filter screen cartridge 4. At this time, the filter screen cartridge 4 in the second filter box 23 is connected to the water storage tank 13, and the circulating water in the water storage tank 13 quickly enters the filter screen cartridge 4 of the second filter box 23 for filtration.

[0058] As the filter screen cartridge 4 in the first filter box 22 continues to release pressure, the first elastic member 55 pushes the top plate 53 and the top rod 57 down, and the top rod 57 continues to push the reversing assembly 2 to rotate under the action of the inclined surface 59 until it is limited by the next arc block 58. At the same time, as the circulating water enters, the filter screen cartridge 4 in the second filter box 23 is subjected to water squeezing force, prompting the reversing assembly 2 to rotate until the receiver 91 detects the position switch of the transmitter 92. At this time, the filter screen cartridge 4 in the first filter box 22 is aligned with the axis of the drain hole 14, and the pump body reduces the delivery pressure to the second set threshold value to prevent the buoyancy column 54 in the second filter box 23 from being lifted up again, causing the position of the filter screen cartridge 4 to be continuously switched.

[0059] After the positions of the first filter box 22 and the second filter box 23 are interchanged, the first flow exchange holes 28 on the second filter box 23 are connected to the outlet pipe 16, and the other first flow exchange holes 28 are in a blocked state. The second flow exchange holes 29 on the first filter box 22 are connected to the return pipe 17, and the other second flow exchange holes 29 are in a blocked state.

[0060] When the receiver 91 detects that the transmitter 92 has exchanged positions, the reversing valve 18 changes direction to send the circulating water in the outlet pipe 16 into the return pipe 17 and increase the pressure through the booster pump, and then enters the support box 31 from the return pipe 17 through the second reversing hole 29 on the first filter box 22 and the third connecting pipe 34 to drive the impeller 33 to rotate, and enters another support box 31 from the second connecting pipe 32 to drive the impeller 33 to rotate, and then flows into the corresponding third connecting pipe 34. The rotation of the impeller 33 drives the filter screen cylinder 4 to rotate. At the same time, the circulating water in the third connecting pipe 34 is sprayed from the nozzle 35 to the surface of the filter screen cylinder 4, thereby automatically backwashing the filter screen cylinder 4 with good flushing effect. The flushed circulating water is discharged from the bottom of the filter screen cylinder 4 through the drain hole 14 and the sewage box 19. After the set time, the reversing valve 18 automatically switches back, and the circulating water continues to be transported from the outlet pipe 16. Through the above-mentioned circulation process, the blocked filter screen cylinder 4 can be automatically detected, switched and cleaned, reducing the maintenance difficulty of the filter cleaner.
