Description

Technical Field

[0001] This utility model relates to the technical field of lotus root processing, and in particular to a lotus root cleaning, sorting and extraction device. Background Technology

[0002] Lotus root is the underground rhizome of the lotus flower, a perennial aquatic plant belonging to the genus Nelumbo of the family Nymphaeaceae. It is a common and nutritious aquatic vegetable, with seven-hole and nine-hole varieties being the most common. Seven-hole lotus roots have a higher starch content and less water content, making them glutinous rather than crisp, and are suitable for soups; nine-hole lotus roots have a higher water content, making them crisp, tender, and juicy, and are suitable for cold dishes or stir-fries.

[0003] The existing announcement number is CN220777333U, which discloses a lotus root cleaning device. The device includes a cleaning tank with multiple equally spaced legs fixed to the bottom. An inlet is located at the top of the tank, and an outlet is located at the bottom; the inlet and outlet are not vertically aligned. The tank contains a stirring mechanism and a brush structure. Lotus roots are placed into the inlet and rotated within the tank by the stirring mechanism for cleaning. This invention utilizes a stirring mechanism to rotate the lotus roots within the tank, and the brush structure effectively cleans the surface of the lotus roots. The cleaned lotus roots are then discharged from the outlet, achieving rapid cleaning of the lotus roots. The device is simple in structure and highly efficient in cleaning.

[0004] While the aforementioned mechanism can move the lotus roots within the washing tank, allowing them to rotate and be cleaned with a brush, the water sprayed through the nozzles causes a mixture of water and sediment to accumulate at the bottom after washing. Since the discharge port is located at the bottom and the lotus roots are discharged via the mechanism, sediment from the surrounding turbid wastewater re-adheres onto the lotus roots as they move towards the discharge port due to water flow and collisions. Simultaneously, some sediment particles that haven't settled are discharged along with the lotus roots due to the pushing force of the lever. This results in some sediment remaining on the surface of the washed lotus roots, requiring a second cleaning and thus reducing the overall cleaning effectiveness. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lotus root washing, sorting, and extraction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A lotus root washing, sorting, and extraction device includes a cylindrical body. One end of the cylindrical body is connected to a feed inlet. A rod is rotatably connected to the cylindrical body. Multiple sets of round rods are connected to one and the other ends of the rod. Multiple sets of discs are connected inside the cylindrical body, each set rotatably connected to the rod. One end of each set of discs is inclined, with a certain gap between its highest point and the inner wall of the cylindrical body. Some of the discs have cavities at one end. Filter screens are connected above two sets of cavities. A drain outlet is provided at one end of the cylindrical body and communicates with the corresponding cavity. A discharge outlet is provided at one end of the cylindrical body and communicates with the bottom of the inner cavity. A hot air blower is installed at one end of the cylindrical body, and a pipe assembly is connected to one end of the hot air blower. Two sets of holes are provided at one end of the cylindrical body, and both sets of holes communicate with the pipe assembly.

[0007] Preferably, one end of the cylinder is connected to a water outlet pipe, which is connected to a corresponding cavity. One end of the water outlet pipe is connected to a box, and a mesh plate is inserted into the box. One end of the box is equipped with a pump body, which is connected to the box body at one end and to a pipe body at the other end. The pipe body penetrates the cylinder and is connected to multiple sets of nozzles in the part inside the cylinder. All sets of nozzles are inclined.

[0008] Preferably, a motor is installed at one end of the cylinder, and the output end of the motor is connected to the rod body through a coupling. An opening is provided at one end of the cylinder, and a block is inserted into the opening. One end of the block is in contact with a corresponding disc, and a bolt is threaded to one end of the block. The bolt is threaded to the opening.

[0009] Preferably, a door is hinged to one end of the box body.

[0010] Preferably, a water inlet valve is connected to one end of the housing.

[0011] Preferably, a drain valve is connected to one end of the housing.

[0012] Preferably, an observation window is embedded at one end of the cylinder.

[0013] The beneficial effects of this utility model are as follows: 1. Through the coordinated operation of the motor, disc, and rod, the operator first feeds the lotus root to be processed into the device through the inlet, starts the motor, and drives the rod to rotate. The continuous agitation of the rod causes the lotus root to tumble within the cylinder, preventing localized accumulation and ensuring that each section of lotus root is fully contacted during the cleaning process. Simultaneously, the pump is activated, drawing out the cleaning solution and delivering it through a pipe to the nozzle. The cleaning solution is sprayed through the nozzle to rinse the surface of the tumbling lotus root, removing mud, sand, and impurities. These impurities fall into the cavity through a filter. The operator can monitor the cleaning status in real time through the observation window and adjust the cleaning time according to the degree of dirt on the lotus root, resulting in a relatively good cleaning effect. After the cleaning process is completed, the bolts are loosened, and the block is removed. At this time, the gap between the plate and the inner wall of the cylinder, which was originally blocked by the block, opens. Under the pushing action of the round rod, the lotus root flows down the inclined plate surface and into the plate below through the gap. The inclined plate can, to a certain extent, prevent too much cleaning liquid from falling into the lower layer with the lotus root. Even if it falls in, it will fall into the cavity through the filter screen and eventually be discharged through the drain. This can, to a certain extent, prevent mud and sand from flowing with the lotus root and achieve a better cleaning effect. 2. Through the coordinated operation of the pump body, tank, and screen, during the lotus root cleaning process, after the cleaning solution sprayed from the nozzles rinses the lotus roots while they are being turned, the wastewater carrying mud, sand, debris, and other impurities naturally falls and flows into the cavity through the filter screen above the tray. It then flows into the tank through the outlet pipe. The tank can intercept small impurities such as mud particles and lotus root peel fragments in the wastewater. The filtered cleaning solution is purified within the tank, restoring it to a clean state, which to a certain extent ensures the cleaning effect during recycling. The purified cleaning solution is then pumped back for reuse, making it widely applicable. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figures 1 to 5A lotus root washing, sorting, and extraction device includes a cylinder 1 with an inlet 2 connected to one end. Lotus roots are fed into the cylinder 1 through the inlet 2. A rod 4 is rotatably connected to the cylinder 1, and the rod 4 drives a round rod 6 to rotate, turning the lotus roots. Multiple sets of round rods 6 are connected to one and the other ends of the rod 4. The inclination angle of the round rods 6 is the same as that of the discs 5. Multiple sets of discs 5 are connected inside the cylinder 1, and each set of discs 5 is rotatably connected to the rod 4. One end of each set of discs 5 is inclined, and there is a gap between the highest point and the inner wall of the cylinder 1 to a certain extent to avoid excessive washing liquid. The lotus root flows into the next process. The round rod 6 moves the lotus root and it falls through the gap to the next process. Some of the discs 5 have cavities 7 at one end. The cleaning liquid falls into the cavity 7 through the filter screen 8. The filter screen 8 is connected to the top of the two sets of cavities 7. The cylinder 1 has a drain outlet 18 at one end, which is connected to the corresponding cavity 7 to drain the residual cleaning liquid. The cylinder 1 has a discharge outlet 19 at one end, which is connected to the bottom of the inner cavity of the cylinder 1. The lotus root flows out from the discharge outlet 19 for subsequent sorting. A hot air blower 20 is installed at one end of the cylinder 1. The model of the hot air blower 20 can be selected according to the actual situation. The appropriate method is selected based on the actual situation. One end of the hot air blower 20 is connected to the pipe assembly 21, which draws in outside air. After heating, the air is sprayed into the cylinder 1 through the pipe assembly 21 and the orifice 22 to dry the lotus root. One end of the cylinder 1 has two sets of orifices 22, both of which are connected to the pipe assembly 21. The lotus root is injected into the cylinder 1 through the feed inlet 2. The motor 3 is started, which drives multiple sets of round rods 6 to rotate through the rod body 4. The rotation of the round rods 6 turns the lotus root. The pump body 14 delivers the cleaning solution through the pipe body 15 to the nozzle 16 to rinse the lotus root. After rinsing for a period of time, the block 24 is extracted. Driven by the round rod 6, the lotus root flows into the lower plate 5 through the gap between the plate 5 and the cylinder 1. The hot air blower 20 draws in outside air, heats it, and sprays it into the cylinder 1 through the pipe group 21 and the hole 22 to dry the lotus root. The round rod 6 drives the lotus root to roll until it falls from the gap onto the bottom plate 5. Driven by the two sets of round rods at the bottom, it falls from the gap to the bottom of the cylinder 1 and flows out from the discharge port 19 for subsequent sorting. This process saves time by removing the lotus roots one by one and improves processing efficiency to a certain extent.

[0018] In this embodiment, one end of the cylinder 1 is connected to a water outlet pipe 9, which is connected to the corresponding cavity 7. The other end of the water outlet pipe 9 is connected to a housing 10, into which a mesh plate 17 is inserted. The mesh plate 17 filters the cleaning fluid flowing into the housing 10, intercepting sediment. The filtered cleaning fluid is then pumped out by a pump 14 for recycling. A pump 14 is installed at one end of the housing 10. The model of the pump 14 can be selected according to actual conditions. One end of the pump 14 is connected to the housing 10, and the other end is connected to a pipe 15. The pump 14 draws the cleaning fluid from the housing 10 and delivers it to the spray nozzle via the pipe 15. The cleaning solution sprays out from the nozzle 16, rinsing the lotus root. At the same time, the rod 4 drives the round rod 6 to rotate, turning the lotus root. This results in a relatively good cleaning effect. The cleaning solution falls into the cavity 7 through the filter screen 8 and flows into the box 10 through the water outlet pipe 9. The pipe 15 penetrates the cylinder 1 and is connected to multiple sets of nozzles 16 inside the cylinder 1. All sets of nozzles 16 are set at an angle, which provides a good rinsing effect on the lotus root. The cleaning solution is recycled through the pump body 14, pipe body 15, nozzles 16, filter screen 8, cavity 7, water outlet pipe 9, box 10, and screen plate 17, making it widely applicable to a certain extent. A motor 3 is installed at one end of the cylinder 1. The model of the motor 3 can be selected according to the actual situation. The output end of the motor 3 is connected to the rod 4 through a coupling. The motor 3 drives the rod 4 to rotate. A port 23 is opened at one end of the cylinder 1. A block 24 is inserted into the port 23. The block 24 seals the gap between the corresponding plate 5 and the cylinder 1, allowing the lotus root to be continuously cleaned. The cleaning process can be observed through the observation window 26. After cleaning, the bolt 25 is unscrewed, and the block 24 is moved. The lotus root is driven by the round rod 6 to fall from the gap between the cylinder 1 and the plate 5 for further processing. One end of the block 24 is in contact with the corresponding plate 5, and the other end of the block 24 is threaded with a bolt 25, which is threaded to the port 23. A door 11 is hinged to one end of the box 10. Opening the door 11 facilitates cleaning inside the box 10. A water inlet valve 12 is connected to one end of the box 10, through which cleaning solution is injected into the box 10. A drain valve 13 is connected to one end of the tank 10 to drain the liquid inside the tank 10. An observation window 26 is embedded in one end of the cylinder 1 to facilitate observation of the lotus root washing process.

[0019] The working principle of this embodiment is as follows: During use, the operator puts the lotus root to be processed into the cylinder 1 through the feed inlet 2, and simultaneously injects an appropriate amount of cleaning liquid through the water inlet valve 12 of the tank 10 to ensure that the liquid level meets the cleaning requirements. The motor 3 is started, and its output end drives the rod 4 to rotate via a coupling. Multiple sets of round rods 6 connected to both ends of the rod 4 rotate synchronously with the rod 4, continuously agitating the lotus root inside the cylinder to prevent local accumulation and ensure that each section of lotus root fully contacts the cleaning process. The pump 14 is turned on, drawing the cleaning liquid from the tank 10 and conveying it through the pipe 15 to multiple sets of inclined nozzles 16 inside the cylinder 1. The cleaning liquid is sprayed out through the nozzles 16, rinsing the surface of the agitated lotus root and removing mud, sand, impurities, and other dirt. After cleaning, the wastewater carrying impurities falls naturally, flowing through the filter screen 8 above the disc 5 into the cavity 7, and then discharged into the tank 10 through the outlet pipe 9. The mesh plate 17 inside the chamber 10 performs secondary filtration of the wastewater, removing tiny particulate impurities. The purified cleaning solution can be pumped back by the pump 14 for recycling, achieving water resource recycling to a certain extent. Operators can observe the lotus root cleaning process in real time through the observation window 26 on the cylinder 1, adjusting the cleaning time according to the degree of dirt to ensure cleaning effectiveness. After cleaning, the bolts 25 are loosened, and the block 24 inserted into the inlet 23 is pulled out, releasing the seal between the disc 5 and the inner wall of the cylinder 1, allowing the lotus root to proceed to the next process. The hot air blower 20 is started, drawing in and heating outside air. The hot air is then delivered through the pipe assembly 21 to the two sets of orifices 22, evenly spraying into the interior of the cylinder 1. Under the continuous turning action of the round rod 6, all parts of the lotus root surface fully contact the hot air, achieving drying. After drying, the lotus roots are pushed by the round rod 6 and fall sequentially along the inclined surface of the disc 5 through the gap between the disc 5 and the inner wall of the cylinder 1, eventually reaching the bottom of the inner cavity of the cylinder 1. They then slide along the inclined bottom surface to the discharge port 19 and are discharged, entering the subsequent sorting process. After the operation is completed, the residual wastewater in the box 10 can be drained through the drain valve 13, and the door 11 can be opened to clean the box 10 and the mesh plate 17 to ensure the cleanliness of the equipment for the next use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
