Description
Technical Field
[0001] This utility model belongs to the field of yam powder processing technology, specifically relating to a high-efficiency yam cleaning device. Background Technology
[0002] Before being processed into powder, yams need to be thoroughly cleaned to remove surface dirt, sand, and other impurities. Traditional cleaning equipment includes a cleaning tank containing nine rotating brush rollers arranged in a front-to-back direction. These rollers form an open-top, arc-shaped cleaning trough inside the tank. Driven by a power unit, the brush rollers rotate in the same direction and at the same speed. A high-pressure water spray pipe is located at the top of the cleaning tank, and a discharge door is located on the rear side wall. The high-pressure water spray pipe is connected to tap water. After the yams are poured into the cleaning tank, they rotate under the influence of the nine brush rollers. The high-pressure water spray pipe wets the yams, while the brush rollers scrub them. The yams rub against each other, removing the dirt from their surface. The dirt is carried downwards by the washing water and flows into the bottom of the cleaning tank, where it is discharged as wastewater. After cleaning, the discharge door is opened, and the cleaned yams are pushed out. The following disadvantages exist in the use of this cleaning equipment: 1) The muddy water after cleaning is not recycled, resulting in high water consumption; 2) Each time the yams to be cleaned are loaded into the cleaning tank, manual operation is always performed after the yams are pushed out, resulting in low loading efficiency; 3) A single high-pressure water spray pipe is used, and the high-pressure water cannot achieve large-area uniform spraying and rinsing; 4) A large number of yams are cleaned in the cleaning tank formed by nine brush rollers. Although the yams are constantly tumbling and rubbing to clean, the yams in the middle are difficult to be brushed by the brush rollers, resulting in poor cleaning effect for some yams. Utility Model Content
[0003] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a high-efficiency yam cleaning device with low water consumption, uniform water spraying, high cleaning efficiency and good cleaning effect.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-efficiency yam cleaning device, including a cleaning tank, with nine brush rollers arranged along the front-to-back direction inside the cleaning tank. The nine brush rollers form an open-top, arc-shaped cleaning trough inside the cleaning tank. The rear side wall of the cleaning tank is provided with a discharge port and a discharge gate for opening and closing the discharge port. A central brush roller located inside the cleaning trough is driven between the front and rear side walls of the cleaning tank. A power mechanism is provided on the front side of the cleaning tank for driving the central brush roller and the nine brush rollers to rotate in the same direction. A circulating water tank is provided at the bottom of the cleaning tank. A high-pressure water spray pipe is provided at the top of the cleaning tank. The inlet of the high-pressure water spray pipe is connected to the circulating water tank through an inlet pipe. A water pump and a first solenoid valve located above the water pump are provided on the inlet pipe. A tap water pipe is connected to the upper part of the inlet pipe. A booster pump and a second solenoid valve are provided on the tap water pipe. Both the first and second solenoid valves are connected to a PLC controller through control lines.
[0005] The central brush roller includes a stainless steel tube with a sealed rear end and an open front end. Several fine water spray holes are opened on the stainless steel tube. A spiral brush is fixed on the stainless steel tube. A rotary joint is provided at the front end of the stainless steel tube. The rotary joint is connected to the water inlet pipe through a connecting pipe. The connection position between the connecting pipe and the water inlet pipe is between the first solenoid valve and the second solenoid valve.
[0006] A filter screen is installed at the front of the circulating water tank, and a water pump is installed inside the circulating water tank at the front of the filter screen.
[0007] The discharge port is a semi-circular ring, and the discharge port is connected to the rear end of the cleaning tank at the bottom of the central brush roller.
[0008] The high-pressure water spray pipeline includes a diagonal support rod fixed on the top of the cleaning tank, two longitudinal main pipes spaced apart on the diagonal support rod and arranged in the front-back direction, the two longitudinal main pipes are connected by several transverse branch pipes, the middle of the foremost longitudinal main pipe is connected to the water inlet pipe, and several rotating nozzles are opened at the bottom of the two longitudinal main pipes and all the transverse branch pipes.
[0009] The right side of the cleaning box is equipped with a feeding mechanism, which includes a motor reducer, a worm gear, a worm wheel, and a tray. The tray is vertically set close to the right side of the cleaning box. The upper left side of the tray is rotatably connected to the top right side of the cleaning box via a hinge. The worm wheel is mounted on the hinge shaft of the hinge, and the hinge shaft is fixedly connected to the tray. The output shaft of the motor reducer is connected to the worm gear drive, and the worm gear meshes with the lower part of the worm wheel for transmission.
[0010] Compared with the prior art, the working principle and beneficial effects of this utility model using the above technical solution are as follows: 1) A circulating water tank is added, and a drainage pipe and a drainage valve are provided on the outside of the circulating water tank; a pumping area is set on the front side of the circulating water tank, and the pumping area is separated from the washing water drop area by a filter screen to filter the mud and sand in the water, so that the water pumped out by the pump has less mud and sand.
[0011] 2) A central brush roller is installed inside the cleaning tank. The central brush roller rotates in the same direction as the nine individual brush rollers. The front end of the central brush roller is connected to the water inlet pipe via a rotary joint and connecting pipe. During cleaning, high-pressure water is introduced and sprayed outwards through fine nozzles to clean the yams in the center of the cleaning tank. Simultaneously, a power mechanism drives the central brush roller to rotate at high speed, and the outer roller brushes of the central brush roller scrub the surface of the yams in contact with it. The power mechanism for the central brush roller can be separate or shared with the power mechanism of the nine individual brush rollers. The power mechanism is already present in existing conventional equipment and will not be described further.
[0012] 3) The high-pressure water spray pipeline is rectangular in shape and is located directly above the cleaning tank, which increases the coverage area. The two longitudinal main pipes simultaneously supply water to all the transverse branch pipes. The water pressure sprayed from each rotating nozzle is basically similar, resulting in uniform water spray and better cleaning effect.
[0013] 4) When not in use, the motor reducer drives the tray downwards via a worm gear and worm wheel, folding it to fit against the right side of the washing tank, saving space. When in use, the motor reducer starts, rotating the tray upwards to a horizontal position. Workers place the yams onto the tray, filling it completely. The motor reducer is then restarted, causing the tray to rotate upwards and to the left. The yams slowly fall into the washing tank, to the right of the central brush roller. After about half the yams have fallen, the motor reducer is stopped, and the central brush roller is started. The rotating central brush roller moves the yams on the right side to the left side of the washing tank. The motor reducer is then restarted, driving the tray upwards until all the yams are in the washing tank. The motor reducer then reverses, rotating the tray downwards to a horizontal position. The water pump, power mechanism, and booster pump are then activated to clean the yams. During the cleaning process, workers place the yams onto the tray. This saves loading time and improves work efficiency.
[0014] 5) The yam cleaning process is as follows: First, open the first solenoid valve and close the second solenoid valve. Start the water pump and power mechanism. The central brush roller and nine bristle rollers rotate in the same direction, tumbling and cleaning the yams in the cleaning tank. The cleaning tank has virtually no dead corners. The water pump draws filtered water from the circulating water tank and sprays it evenly onto the yam surface through fine nozzles and rotating spray heads. Combined with the rotating brushes, this greatly improves the cleaning effect and efficiency. Initially, the water pump draws turbid water from the circulating tank for preliminary cleaning of the yams. The PLC controller sets the water pump to work for a period of time (e.g., 5 minutes). The PLC controller then stops the water pump, opens the second solenoid valve, closes the first solenoid valve, and starts the booster pump. The booster pump draws tap water (clean water) for a secondary deep cleaning of the yams. After the booster pump works for a period of time (e.g., 3 minutes), the yam cleaning operation is complete. The PLC controller then stops the water pump, closes the second solenoid valve, and shuts down the power mechanism. Then open the discharge door, start the power mechanism, and the central roller brush rotates. Since the brush on the outer circle of the central roller brush is spirally arranged, the yam can be driven to move backward during the rotation of the central roller brush. There is a receiving sieve on the rear side wall of the washing box located below the discharge port. The yam is automatically discharged from the discharge port and falls onto the receiving sieve.
[0015] In summary, this utility model is based on sound principles. It adds a central brush roller, improves the high-pressure water spray pipeline, and adds a circulating water tank and water pump to the existing yam cleaning equipment. It uses circulating water for preliminary cleaning and then uses clean water for deep cleaning, thus saving water. The feeding mechanism allows workers to load the yams into trays during the cleaning process, making the feeding in the upper cleaning tank faster and significantly improving work efficiency and cleaning effect.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0022] like Figures 1-5 As shown, the yam high-efficiency cleaning device of this utility model includes a cleaning tank 1. Nine brush rollers 2 are arranged along the front-to-back direction inside the cleaning tank 1, forming an open-topped, arc-shaped cleaning trough 3. A discharge port 4 and a discharge gate 5 for opening and closing the discharge port 4 are provided on the rear side wall of the cleaning tank 1. A central brush roller 6 located inside the cleaning trough 3 is driven between the front and rear side walls of the cleaning tank 1. A device on the front side of the cleaning tank 1 is provided to drive the central brush roller 6 and the nine brush rollers 2 to rotate in the same direction. The power mechanism of the cleaning tank 1 includes a circulating water pool 7 at the bottom and a high-pressure water spray pipe at the top. The inlet of the high-pressure water spray pipe is connected to the circulating water pool 7 via an inlet pipe 8. The inlet pipe 8 is equipped with a water pump 9 and a first solenoid valve 10 located above the water pump 9. A tap water pipe 11 is connected to the upper part of the inlet pipe 8. A booster pump 12 and a second solenoid valve 13 are installed on the tap water pipe 11. Both the first solenoid valve 10 and the second solenoid valve 13 are connected to a PLC controller (not shown in the figure) via control lines.
[0023] The central brush roller 6 includes a stainless steel tube with a sealed rear end and an open front end. Several water spray holes are opened on the stainless steel tube. A spiral brush is fixed on the stainless steel tube. A rotary joint 14 is provided at the front end of the stainless steel tube. The rotary joint 14 is connected to the water inlet pipe 8 through a connecting pipe 15. The connection position between the connecting pipe 15 and the water inlet pipe 8 is between the first solenoid valve 10 and the second solenoid valve 13.
[0024] A filter screen 16 is provided on the front side of the circulating water tank 7, and a water pump 9 is installed in the circulating water tank 7 on the front side of the filter screen 16.
[0025] The discharge port 4 is a semi-circular ring, and the discharge port 4 is connected to the rear end face of the cleaning tank 3 at the bottom of the central brush roller 6.
[0026] The high-pressure water spray pipeline includes a diagonal support rod 17 fixed on the top of the cleaning tank 1, two longitudinal main pipes 18 spaced apart on the diagonal support rod 17 and arranged in the front-back direction, the two longitudinal main pipes 18 are connected by several transverse branch pipes 19, the middle of the foremost longitudinal main pipe 18 is connected to the water inlet pipe 8, and several rotating nozzles 20 are opened at the bottom of the two longitudinal main pipes 18 and all the transverse branch pipes 19.
[0027] A feeding mechanism is provided on the right side of the cleaning tank 1. The feeding mechanism includes a motor reducer 21, a worm gear 22, a worm wheel 23, and a tray 24. The tray 24 is vertically arranged close to the right side of the cleaning tank 1. The upper left side of the tray 24 is rotatably connected to the top right side of the cleaning tank 1 via a hinge. The worm wheel 23 is mounted on the hinge shaft 25 of the hinge. The hinge shaft 25 is fixedly connected to the tray 24. The output shaft of the motor reducer 21 is connected to the worm gear 22 for transmission. The worm gear 22 and the lower part of the worm wheel 23 mesh for transmission.
[0028] The working principle and beneficial effects of this utility model are as follows: 1) A circulating water tank 7 is added, and a drainage pipe 28 and a drainage valve 29 are provided on the outside of the circulating water tank 7; a water pumping area is set on the front side of the circulating water tank 7, and the water pumping area is separated from the washing water drop area by a filter screen 16 to filter the mud and sand in the water, so that the water pumped out by the water pump 9 has less mud and sand.
[0029] 2) A central brush roller 6 is installed inside the cleaning tank 3. The central brush roller 6 rotates in the same direction as the nine brush rollers 2. The front end of the central brush roller 6 is connected to the water inlet pipe 8 through a rotary joint 14 and a connecting pipe 15. During cleaning, high-pressure water is introduced and sprayed outward through the spray nozzles to clean the yam 26 in the middle of the cleaning tank 3 with high-pressure water. At the same time, the power mechanism drives the central brush roller 6 to rotate at high speed, and the roller brush on the outer circle of the central brush roller 6 brushes the surface of the yam 26 it contacts. The power mechanism of the central brush roller 6 can be set separately or shared with the power mechanism of the nine brush rollers 2. The power mechanism is in existing conventional equipment and will not be described in detail.
[0030] 3) The high-pressure water spray pipeline is rectangular in shape and is set directly above the cleaning tank 3, which increases the coverage area. The two longitudinal main pipes 18 simultaneously supply water to all the transverse branch pipes 19. The water pressure sprayed from each rotating nozzle 20 is basically similar, resulting in uniform water spray and better cleaning effect.
[0031] 4) When not in use, the motor reducer 21 drives the tray 24 to rotate downwards and fold into place with the right side of the cleaning tank 1 through the worm gear 22 and worm wheel 23, thus saving space. When this invention is in use, the motor reducer 21 starts and rotates the tray 24 upward to a horizontal position. The worker places the yams 26 onto the tray 24. Once full, the motor reducer 21 is restarted, and the tray 24 rotates to the upper left. The yams 26 on the tray 24 slowly fall into the right side of the central brush roller 6 in the washing tank 3. After about half of the yams 26 have fallen, the motor reducer 21 is stopped, and the central brush roller 6 is started. The central brush roller 6 rotates, driving the yams 26 on the right side to the left side of the washing tank 3. The motor reducer 21 is then started again, causing the tray 24 to continue rotating upward until all the yams 26 on the tray 24 have been poured into the washing tank 3. The motor reducer 21 then reverses, rotating the tray 24 downward to a horizontal position. The water pump 9, power mechanism, and booster pump 12 are then started to clean the yams 26. During the cleaning process, the worker places the yams 26 onto the tray 24. This saves loading time and improves work efficiency.
[0032] 5) The specific cleaning process for yam 26 is as follows: First, open the first solenoid valve and close the second solenoid valve 13. Start the water pump 9 and the power mechanism. The central brush roller 6 and the nine brush rollers 2 rotate in the same direction, performing a flipping cleaning of the yam 26 in the cleaning tank 3. The cleaning tank 3 has virtually no dead corners. The water pump 9 draws out the filtered water from the circulating water tank 7 and sprays it evenly onto the surface of the yam 26 through the fine spray holes and rotating nozzles 20. Combined with the rotating cleaning of the brushes, the cleaning effect and efficiency are greatly improved. Initially, the water pump 9 draws the turbid water filtered from the circulating tank to perform a preliminary cleaning of the yam 26. The PLC controller sets the water pump 9 to work for a period of time (e.g., 5 minutes). The PLC controller then stops the water pump 9, the second solenoid valve 13 opens, the first solenoid valve 10 closes, and the booster pump 12 starts. The booster pump 12 draws tap water (clean water) to perform a secondary deep cleaning of the yam 26. After the booster pump 12 works for a period of time (e.g., 3 minutes), the cleaning operation of the yam 26 is completed. The PLC controller stops the water pump 9, closes the second solenoid valve 13, and shuts down the power mechanism. Then, the discharge gate 5 is opened, the power mechanism is started, and the central roller brush rotates. Because the brush on the outer circle of the central roller brush is spirally arranged, the rotation of the central roller brush can drive the yam 26 to move backward. A receiving sieve 27 is provided on the rear side wall of the washing tank 1 below the discharge port 4. The yam 26 is automatically discharged from the discharge port 4 and falls onto the receiving sieve 27.
[0033] It should be emphasized that the PLC controller, first solenoid valve 10, second solenoid valve 13, water pump 9, booster pump 12, motor reducer 21, turbine, worm gear 22, and rotary nozzle 20 in this utility model are all existing mature technologies, and their specific structures will not be described in detail. The automatic control involved does not involve any new computer programs.
[0034] The above embodiments illustrate the basic principles and features of this utility model. However, the above descriptions are merely preferred embodiments and are not limited to these embodiments. Those skilled in the art, inspired by this patent, can make many modifications and improvements without departing from the spirit and scope of the claims, all of which fall within the protection scope of this utility model.
