Opposite vertical plates 27 are provided on the top surface of the support plate 26. The vertical plates 27 are provided with sliding grooves 28. The filter belt mechanism is slidably arranged in the sliding grooves 28. The vertical plates 27 are used to provide support when the filter belt mechanism is completely moved out of the housing 1. The frame 3 is arranged on the side surface of the housing 1. A moving mechanism is arranged at the top of the frame 3. A second electric push rod 17 is arranged at the bottom of the moving mechanism. The telescopic end of the second electric push rod 17 is provided with a second U-shaped frame 25. A second rotating shaft 15 is rotatably arranged in the middle of the second U-shaped frame 25. One end of the second rotating shaft 15 is rotatably connected to the second U-shaped frame 25, and the other end passes through the second U-shaped frame 25 and is driven by a second motor 10. A brush barrel 11 is sleeved on the second rotating shaft 15. Brush hairs 12 are arranged on the brush barrel 11. A debris collection box 13 is arranged below the filter belt mechanism. The controller 20 is arranged on the top surface of the frame 3 and is electrically connected to the filter belt mechanism, the first motor 5, the second motor 10, the first electric push rod 7, the second electric push rod 17 and the moving mechanism. The controller 20 uses a low-power microprocessor with the model of STM32-L0.

[0025] When the filtering and impurity removing device is working, coconut juice is poured into the housing 1 from the feed hopper 2. After being filtered by the filter belt mechanism, the coconut juice continues to flow down to the bottom inside the housing 1, and the solid impurities will be isolated at the top by the filter belt mechanism. After a predetermined time, the controller 20 activates the filter belt mechanism, and the filter belt mechanism transfers the solid impurities from the opening 33 to the outside of one side of the housing 1. Finally, the solid impurities fall into the impurity collection box 13 to complete the filtering and impurity removing operation of the coconut juice. When the filter belt mechanism is blocked or damaged, the controller 20 activates the first motor 5 and the first electric push rod 7. The first motor 5 rotates to drive the first rotating shaft 9 to rotate, and the first rotating shaft 9 rotates to drive the first electric push rod 7 to rotate. At the same time, the telescopic end of the first electric push rod 7 extends, so as to drive the first U-shaped frame 8 to move. The first U-shaped frame 8 moves to drive the filter belt mechanism to move out of the housing 1 along the sliding groove 28 from the opening 33. Then, the moving mechanism and the second motor 10 are activated. The moving mechanism drives the second electric push rod 17 to move, and the second electric push rod 17 moves to drive the second U-shaped frame 25 to move. At the same time, the second motor 10 rotates to drive the second rotating shaft 15 to rotate, the second rotating shaft 15 rotates to drive the brush barrel 11 to rotate, and the brush barrel 11 rotates to drive the bristles 12 to rotate, so that the bristles 12 clean the filter belt mechanism, remove the blockage, and at the same time clean the filter belt mechanism. The filter belt mechanism can be completely moved out of the housing 1, which is convenient for the maintenance and replacement operations of the filter belt mechanism.

[0026] Preferably, the filter belt mechanism includes rotating rollers 29, sliding rods 19 and a filter belt 18. A plurality of the rotating rollers 29 are arranged between the two sliding rods 19. The sliding rods 19 are slidably arranged in the sliding grooves 28, and the filter belt 18 is sleeved on the plurality of rotating rollers 29.

[0027] When the filter belt mechanism is working, first insert the sliding rod 19 into the sliding groove 28 from the opening 33, and then move along the sliding groove 28 to the inner wall side of the housing 1. The coconut juice falls onto the top surface of the filter belt 18 from above. The coconut juice can pass through the filter belt 18 and fall into the bottom of the housing 1, while the solid impurities are isolated on the top surface by the filter belt 18, playing a role in filtering and impurity removing. After the filter belt 18 is used for a period of time, start the rotating roller 29. The rotating roller 29 rotates to drive the filter belt 18 to move, and the solid impurities accumulated on the top surface of the filter belt 18 can be removed; when the filter belt 18 is blocked, start the rotating roller 29. The rotating roller 29 rotates to drive the filter belt 18 to move, and the blocked part of the filter belt 18 can be moved outside the housing 1 for easy handling and problem elimination.

[0028] Preferably, the moving mechanism includes a lead screw 4, a third motor 16 and a moving block 6. The lead screw 4 is rotatably arranged on the top of the frame 3, one end of which is rotatably connected to the housing 1, and the other end passes through the frame 3 and is driven by the third motor 16. The third motor 16 is arranged on the side of the frame 3. The second motor 10 is a stepping motor that can accurately control the rotation angle. The moving block 6 is arranged on the lead screw 4.

[0029] When the filter belt 18 becomes blocked or damaged, the first motor 5 and the first electric push rod 7 are started, and the filter belt 18 can be moved out of the housing 1. Then, the moving mechanism is started, and the third motor 16 rotates to drive the lead screw 4 to rotate. The rotation of the lead screw 4 drives the moving block 6 to move along the direction of the lead screw 4, thereby driving the second electric push rod 17 to move, facilitating the cleaning of the filter belt 18.

[0030] Preferably, it further includes a impurity removing mechanism. The impurity removing mechanism includes a rubber partition 30, a third rotating shaft 31, and a fourth motor 32.

One end of it is rotatably connected to the housing 1, and the other end passes through the housing 1 and is driven by a fourth motor 32. The fourth motor 32 is arranged on the side of the housing 1. The fourth motor 32 is a stepping motor that can precisely control the rotation angle, and the rubber partition 30 is fixedly arranged on the third rotating shaft 31.

[0031] After the filter and impurity removing device works for a period of time, solid impurities will accumulate on the filter belt 18. At this time, the fourth motor 32 is started. The rotation of the fourth motor 32 drives the third rotating shaft 31 to rotate. The rotation of the third rotating shaft 31 drives the rubber partition 30 to rotate. Then, the rotating roller 29 is started. The rotation of the rotating roller 29 drives the filter belt 18 to move, so as to take the solid debris on the top surface of the filter belt 18 out of the housing 1 through the opening 33. Then, the fourth motor 32 is restarted to reset the rubber partition 30, and the rubber partition 30 closes the opening 33.

[0033] By opening the discharge valve 24, the coconut juice can be discharged from the discharge pipe 23, and the discharge amount and discharge time of the coconut juice can be controlled. By adjusting the opening degree of the discharge valve 24, the fine adjustment of the coconut juice flow rate can be realized to meet different production requirements.

[0034] Preferably, it further includes a bearing 34. The bearing 34 is arranged on the side of the housing 1, and the end of the lead screw 4 away from the third motor 16 is rotatably connected to the bearing 34.

[0035] The bearing 34 is arranged on the side of the housing 1, which can stably support the lead screw 4 and prevent it from shifting or shaking during rotation.

[0036] Preferably, an inclined part 22 is arranged at the bottom inside the housing 1, and the lower part of the inclined part 22 is located on one side of the discharge pipe 23.

[0037] The coconut juice is affected by gravity in the housing 1 and flows along the inclined portion 22 towards the side of the discharge pipe 23, which helps to accelerate the flow rate of the coconut juice, reduce the residence time in the housing 1, and thus improve the filtration efficiency.

[0038] Preferably, it further includes support legs 21, and a plurality of the support legs 21 are arranged on the bottom surface of the housing 1.

[0039] The support legs 21 provide support for the housing 1 to ensure that the filtering device remains stable during operation and prevent the device from shaking or tilting.
