Description

Technical Field

[0001] This utility model relates to the field of raisin cleaning technology, and specifically to a raisin cleaning device. Background Technology

[0002] Raisins, a popular dried fruit, are prone to accumulating dust and sand on their surface during the harvesting, drying, dehydration, and subsequent processing of grapes. Inadequate cleaning not only affects the taste and appearance of the raisins but may also pose potential health risks to consumers. To meet this demand, various raisin cleaning devices have emerged on the market.

[0003] The existing cleaning device mainly includes a cleaning tank, a spray assembly, and a conveying mechanism. By injecting clean water into the cleaning tank, the raisins are tumbled and soaked in the water using a conveyor belt, while high-pressure water jets are sprayed from the top spray head to rinse the surface of the raisins.

[0004] However, existing raisin cleaning equipment uses a one-time water rinsing mode in actual use. The spray components continuously spray fresh water, and the wastewater after cleaning is directly discharged through the drain outlet. It cannot be recycled, resulting in a large waste of recyclable water resources and increasing the cost of production water. Utility Model Content

[0005] The purpose of this invention is to provide a raisin cleaning device to solve the problem that existing raisin cleaning devices use a single-use water rinsing mode, which does not allow for water recycling, resulting in water waste and increased production water costs.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a raisin washing device, including a support frame, on which a shell and a soaking tank are provided. The tops of the shell and the soaking tank are open, and the side walls of the shell and the soaking tank are fixedly connected to each other. A rotating cylinder is rotatably connected inside the shell. Several sieve holes are evenly distributed on the rotating cylinder, and both ends of the rotating cylinder are open. A driving component for driving the rotating cylinder to rotate is provided on the support frame. One end of the rotating cylinder rotatably extends through the shell into the soaking tank. The rotating cylinder is inclined towards one side of the soaking tank. A spiral plate is provided on the inner wall of the rotating cylinder. A water tank is provided at the bottom of the support frame. A water supply pipe is connected to one side of the water tank. One end of the water supply pipe is connected to the soaking tank. A water pump is provided on the water supply pipe. A drain pipe is connected to one side of the shell. One end of the drain pipe is connected to the water tank. The ends of the drain pipe and the water supply pipe connected to the water tank are respectively located on opposite sides of the water tank. A partition is detachably connected inside the water tank. The partition is located between the drain pipe and the water supply pipe.

[0007] The working principle of this utility model is as follows: A raisin washing device, when raisins need to be washed, firstly, the raisins fall into the soaking tank via a conveyor belt. At the same time, a water pump delivers clean water from the side of the water tank near the water supply pipe to the soaking tank through the water supply pipe until the water level in the soaking tank reaches the height that can completely submerge the extended end of the rotating drum, thus soaking the raisins. Then, the rotating drum is driven by the drive assembly to rotate inside the shell. The spiral plate on the inner wall of the rotating drum moves the raisins from the soaking tank to the other end. The raisins tumble and collide inside the rotating drum. With the help of the sieve holes on the rotating drum, only impurities and water are allowed to pass through, thus separating the raisins from the impurities. The washed water and impurities enter the interior of the shell through the sieve holes and are then discharged into the water tank near the drain pipe side of the shell for sedimentation. Because the partition divides the water tank into a sedimentation zone and a clear water zone, the sewage discharged into the water tank from the drain pipe first enters the sedimentation zone and settles naturally under gravity. The clear water that has been clarified at the top slowly overflows from the top of the partition to the clear water zone. The water in the clear water zone is pumped back to the soaking tank through the water supply pipe, thus realizing the recycling of water.

[0008] The beneficial effects of this utility model are as follows: the partition divides the water tank into a sedimentation zone (near the drain pipe) and a clear water zone (near the water supply pipe). After the sewage carrying impurities is discharged into the sedimentation zone through the drain pipe, the mud and sand in the sewage naturally settle to the bottom of the sedimentation zone under the action of gravity, preventing impurities from directly entering the clear water zone with the water flow. After the clear water in the sedimentation zone is settled and clarified, it will slowly overflow from the top of the partition to the clear water zone, and then be recycled through the water supply pipe and water pump.

[0009] Option 2, a preferred embodiment of the basic option, includes a motor fixedly connected to a support frame. A rotating shaft is rotatably connected inside the housing. A gear ring is provided on the outer side of the rotating drum. A gear for meshing with the gear ring is provided on the rotating shaft. A belt is provided between the rotating shaft, which rotatably extends through the housing, and one end of the shaft and the motor's electric shaft. The drive assembly uses a motor to drive the gear ring on the outer side of the rotating drum to rotate via a belt, rotating shaft, and gear. The structure is simple and stable, providing reliable power to the rotating drum and ensuring its rotational speed and stability.

[0010] Option 3, a preferred embodiment of the basic option, features sliders on both sides of the partition, a groove on the inner wall of the water tank, and the sliders slidably connected to the groove. A sliding rod is located on one side of the partition and slidably connected to the water tank. Two through-slots are located at the bottom of the water tank, on opposite sides of the partition, and each through-slot can be detachably fitted with a cover. When sediment accumulates at the bottom of the water tank, the corresponding cover can be opened to directly discharge the impurities from the through-slot, reducing the workload of cleaning the water tank and preventing long-term accumulation of impurities.

[0011] Option 4, a preferred embodiment of Option 3, involves hinged one end of the cover to the bottom of the water tank and bolted the other end to the bottom of the water tank. A sealing rubber body is provided on one side of the cover embedded in the through groove to seal the groove. This connection method facilitates opening and closing the cover, while the sealing rubber body effectively prevents water leakage from the water tank, ensuring its airtightness and normal operation.

[0012] Option 5, which is a preferred option of the basic option, is that a spray pipe is connected to the water supply pipe, and a nozzle is provided at one end of the spray pipe. The nozzle is located on the side of the rotating drum away from the soaking tank. The spray pipe and nozzle connected to the water supply pipe can spray and clean the raisins on the side of the rotating drum away from the soaking tank, which further improves the cleaning effect of the raisins and can more thoroughly rinse the surface of the raisins to remove residual impurities.

[0013] Option 6, which is a preferred option of the basic option, is provided with a filter screen at the top of the partition; the filter screen at the top of the partition can filter the water flowing back into the water tank from the drain pipe, thereby improving the cleanliness of the circulating water.

A rotating drum 4 is rotatably connected inside the shell 2. Several sieve holes are evenly distributed on the rotating drum 4, and both ends of the rotating drum 4 are open. A drive assembly for driving the rotating drum 4 to rotate is provided on the support frame 1. The drive assembly includes a motor 14, which is fixedly connected to the support frame 1. A rotating shaft 11 is rotatably connected inside the shell 2. A gear ring 12 is provided on the outer side of the rotating drum 4. A gear 13 for meshing with the gear ring 12 is provided on the rotating shaft 11. A belt 15 is provided between the rotating shaft 11, which rotatably passes through the shell 2 and extends to one end of the shell 2 and the electric shaft of the motor 14.

[0017] One end of the rotating drum 4 rotates through the shell 2 and extends into the soaking tank 3. The rotating drum 4 is tilted towards one side of the soaking tank 3. A spiral plate 5 is provided on the inner wall of the rotating drum 4. A water tank 6 is provided at the bottom of the support frame 1. A water supply pipe 7 is connected to one side of the water tank 6. One end of the water supply pipe 7 is connected to the soaking tank 3. A water pump 8 is provided on the water supply pipe 7. A drain pipe 9 is connected to one side of the shell 2. One end of the drain pipe 9 is connected to the water tank 6. The ends of the drain pipe 9 and the water supply pipe 7 connected to the water tank 6 are located on opposite sides of the water tank 6. A partition 10 is detachably connected inside the water tank 6. A filter screen 24 is provided on the top of the partition 10. The partition 10 is located between the drain pipe 9 and the water supply pipe 7. Slider blocks 16 are provided on both sides of the partition 10. A sliding groove 17 is opened on the inner wall of the water tank 6. The slider 16 is slidably connected to the sliding groove 17. A sliding rod 18 is provided on one side of the partition 10. The sliding rod 18 is slidably connected to the water tank 6. A sealing structure is provided between the sliding rod 18 and the water tank 6. The sealing structure is a packing seal. The bottom of the water tank 6 is provided with two through slots, which are located on both sides of the partition plate 10. Each through slot is detachably connected to a cover 20. One end of the cover 20 is hinged to the bottom of the water tank 6, and the other end is bolted to the bottom of the water tank 6. The side of the cover 20 that is embedded in the through slot 19 is provided with a sealing rubber body 21 for sealing the through slot 19. A spray pipe 22 is connected to the water supply pipe 7. One end of the spray pipe 22 is threadedly connected to a nozzle 23. The nozzle 23 is located on the side of the rotating drum 4 away from the soaking tank 3. The nozzle 23 is flat and needs to be cleaned or replaced regularly.

[0018] A water supply pipe is installed on the side of water tank 6 near the water supply pipe 7. An electric shut-off valve is mounted on the water supply pipe. A level gauge is installed on the inner wall of the water tank near the water supply pipe, and the level gauge is electrically connected to a PLC controller. The electric shut-off valve is also electrically connected to the PLC controller. Clean water is injected into water tank 6 through the water supply pipe near the water supply pipe 7. The level gauge monitors the water level in water tank 6 in real time and transmits the data to the PLC controller. When the water level reaches a preset standard, the PLC controller automatically closes the electric shut-off valve on the water supply pipe, stopping the water supply.

[0019] The implementation method of this embodiment is as follows: When it is necessary to clean the raisins, the raisins first fall into the soaking tank 3 via a conveyor belt. At the same time, the water pump 8 delivers clean water from the side of the water tank 6 near the water supply pipe 7 to the soaking tank 3 through the water supply pipe 7 until the water level in the soaking tank 3 reaches the height that can completely submerge the extended end of the rotating drum 4, thus soaking the raisins. Then, the motor 14 is started, and the motor shaft of the motor 14 drives the rotating shaft 11 to rotate via the belt 15. The gear 13 on the rotating shaft 11 meshes with the gear ring 12 on the outer side of the rotating drum 4, thereby driving the rotating drum 4 to rotate inside the housing 2. The spiral plate 5 on the inner wall of the rotating drum 4 moves the raisins from the soaking tank 3 to the other end. The raisins tumble and collide inside the rotating drum 4, cooperating with the rotating drum 4. The sieve holes only allow impurities and water to pass through, thus separating the raisins from the impurities. After washing, the water and impurities enter the interior of the shell 2 through the sieve holes, and then are discharged into the water tank 6 near the drain pipe 9 on one side of the shell 2 for sedimentation. At the same time, as the raisins move away from the soaking tank 3 in the rotating drum 4 (moving to the middle position of the rotating drum 4), the spray pipe 22 connected to the water supply pipe 7 sprays the raisins tumbling inside the rotating drum 4 for a second time to clean them, further cleaning the raisins. The wastewater after spraying also enters the shell 2 through the sieve holes of the rotating drum 4, and finally flows into the water tank 6 with the drain pipe 9. The raisins that have been washed twice are then discharged from the opening of the rotating drum 4 away from the soaking tank 3 by the spiral plate 5, completing the washing process.

[0020] Since the partition 10 divides the water tank 6 into a sedimentation zone and a clear water zone, the sewage discharged into the water tank 6 from the drain pipe 9 first enters the sedimentation zone and settles naturally under gravity. The clear water that has been clarified at the top slowly overflows from the top of the partition 10 to the clear water zone. At the same time, the filter screen 24 filters the water. The water in the clear water zone is pumped back to the soaking tank 3 and the spray pipe 22 by the water supply pipe 7, so as to realize the recycling of water.

[0021] After the device has been running for a period of time, when a certain amount of mud and sand accumulates at the bottom of the sedimentation zone of water tank 6, first unscrew the bolts at one end of the cover 20, flip the cover 20 downward around the hinge end to open it, and the mud, sand and impurities and water at the bottom of the sedimentation zone are discharged through the channel. Then, push the partition 10 along the slide 17 through the sliding rod 18 to discharge the impurities at the bottom of the clear water zone and sedimentation zone from the channel. After cleaning, close the cover 20 and tighten the bolts again to ensure that the sealing rubber body 21 seals the channel.
