Description

Technical Field

[0001] This invention relates to the field of rice processing technology, specifically to a rice washing and rinsing device with a water flow washing structure. Background Technology

[0002] Rice washing and cleaning devices are essential equipment in rice processing, primarily used to remove impurities, dust, and excess starch from the surface of rice to ensure the cleanliness and quality of the final product. These devices typically consist of an inlet, a washing tank, a water pump, a screen, and an outlet. The washing tank is the core component, using water flow to achieve cleaning. The water pump provides the necessary water flow, while the screen filters out impurities and excess water, ensuring the washed rice is clean and free of impurities. In operation, the rice to be washed enters the washing tank through the inlet. The water pump draws clean water into the tank, creating a water flow. Under the impact of this flow, impurities and excess starch on the rice surface are effectively removed, while the water flow also carries away impurities, causing them to settle at the bottom of the tank. The screen at the bottom of the washing tank blocks impurities, ensuring the washed rice is not contaminated. The washed rice is finally discharged through the outlet to enter subsequent processing stages.

[0003] For example, the rice processing and cleaning device disclosed in the authorization announcement number CN222220467U includes: a cleaning tank, one side of which is connected to an inlet and an outlet, and a spray washing mechanism embedded on one side of the cleaning tank. The mechanism feeds rice from the inlet onto the surface of the bottom plate, and water flows through the nozzle to spray high-pressure water to wash the rice on the bottom plate surface. Dust in the rice flows into the tank with the water through the filter holes. It can be seen that the existing rice washing technology and cleaning operation methods are basically the same, that is, under the impact of water flow, impurities and excess starch on the surface of rice are washed away. However, in the above technical solution, the movement of water flow is mainly concentrated in the upper layer, and the rice particles at the bottom of the cleaning tank cannot fully contact the impact of water flow. Some areas may be impacted more strongly, while other areas may be relatively weaker. This means that the rice at the bottom cannot be effectively cleaned, resulting in the residue of impurities and starch. In addition, there is a long time interval between the discharge of rice water during and after the cleaning process. The long water level not only increases the cleaning cycle, but also causes the re-sedimentation of impurities in the water, reducing the efficiency of subsequent cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a rice washing and rinsing device with a water flow cleaning structure. A water pump pumps clean water into a cage-type high-pressure vortex water curtain assembly through a rotary joint. A sprocket drive assembly drives the driven rice slurry and the cage-type high-pressure vortex water curtain assembly to rotate. The rotating cage-type high-pressure vortex water curtain assembly sprays clean water to various positions of the rice material in the washing drum, realizing the function of simultaneously rotating and spraying to agitate the rice material. During the washing process, a stepped liquid discharge structure is used for liquid replacement and waste discharge. After the washing is completed, a flap-type pneumatic discharge assembly opens to discharge the rice material in the washing drum, thereby solving the problems mentioned in the background art.

[0009] Preferably, the cage-type high-pressure vortex water curtain assembly includes an upper liquid inlet head rotatably installed at the center of the partition, a hollow vertical pipe installed at the bottom of the upper liquid inlet head, a lower liquid storage head installed at the bottom of the hollow vertical pipe, and a plurality of C-shaped nozzles arranged in a ring array between the outer walls of the hollow vertical pipe and the lower liquid storage head. The outer wall of the C-shaped nozzles is provided with a plurality of equally spaced spray holes along the Z-axis direction. The driven rice slurry is connected to the upper liquid inlet head through a three-gear transmission structure. The top end of the upper liquid inlet head is fixedly connected to the bottom end of the liquid outlet pipe of the rotary joint.

[0010] Preferably, the top of the upper liquid inlet head is integrally formed with several equally spaced arc-shaped ribs, and a gap is provided between two adjacent arc-shaped ribs.

[0011] Preferably, the three-gear transmission structure consists of a primary gear, a secondary gear shaft, and a tertiary gear ring. The primary gear is installed at the top of the driven rice slurry turner, the secondary gear shaft is rotatably installed at one edge of the top of the partition plate, and the tertiary gear ring is fixed to one end of the surface of the upper liquid inlet head. The primary gear, the secondary gear shaft, and the tertiary gear ring mesh sequentially, and the motor drives the driven rice slurry turner and the primary gear to rotate through a sprocket transmission structure.

[0012] Preferably, the C-shaped nozzle is made of stainless steel and has a length of 1.5 meters to 2 meters.

[0013] Preferably, the flap-type pneumatic discharge assembly includes a cylinder platform installed on one side of the outer wall of the washing drum, a cylinder hinged to the bottom of the cylinder platform, and an end plate fixed on one side of the outer wall of the washing drum. The end of the end plate away from the washing drum is hinged with a bent arm, and the end of the bent arm away from the washing drum is hinged to the bottom of the piston rod of the cylinder through a fisheye joint. The other end of the bent arm is hinged with a gate plate, which is located below the lower liquid storage head.

[0014] Preferably, the stepped drainage structure includes a collection pipe located below the feed chute, an upper solenoid valve and a lower solenoid valve installed on the outer wall of the collection pipe near the washing drum, and a drainage pipe installed at the end of the upper and lower solenoid valves away from the collection pipe. The end of the drainage pipe extends into the interior of the washing drum and is fitted with a filter disc.

[0015] Preferably, the sprocket drive structure includes a drive sprocket mounted on the top of the motor output shaft, a driven sprocket fixed to one end of the driven rice paste surface, and a chain mounted between the driven sprocket and the drive sprocket.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This rice washing and rinsing device with a water flow washing structure is equipped with a washing drum, a cage-type high-pressure vortex water curtain assembly, a driven rice slurry turning assembly, an upper and lower stepped liquid discharge structure, a gate-type pneumatic discharge assembly, and other mutually cooperating structures. An external water pump pumps clean water into the cage-type high-pressure vortex water curtain assembly through a rotary joint under high pressure. A sprocket drive assembly drives the driven rice slurry turning assembly and the cage-type high-pressure vortex water curtain assembly to rotate. The rotating cage-type high-pressure vortex water curtain assembly sprays clean water onto various positions of the rice material in the washing drum, achieving the function of simultaneously rotating and spraying while agitating the rice material. During the washing process, the upper and lower stepped liquid discharge structure replaces the liquid and discharges waste. After washing, the gate-type pneumatic discharge assembly... The pneumatic discharge assembly opens, allowing the rice in the washing drum to be discharged. The cage-type high-pressure vortex water curtain assembly is designed to spray clean water evenly onto all parts of the rice in the washing drum under high pressure. Due to the uniform distribution of water flow, it ensures that every grain of rice is fully impacted and cleaned. The sprocket-driven cage-type high-pressure vortex water curtain assembly and the driven rice slurry also keep the rice in the washing drum dynamically turning during the washing process. The continuous turning of the rice during this process not only increases the contact area with the water flow, but also effectively breaks the stickiness between the rice grains, making it easier to wash away impurities. Under the effect of dynamic disturbance, the cleaning effect is significantly improved, ensuring that the rice is thoroughly cleaned during the washing process.

[0017] Secondly, the stepped drainage structure used in the cleaning process allows for liquid replacement and waste discharge simultaneously. This means that old wastewater and impurities can be discharged promptly during and after cleaning, preventing a decline in cleaning effectiveness due to wastewater accumulation and maintaining the continuity and efficiency of the cleaning process while reducing cleaning time. Finally, after cleaning, the design of the flap-type pneumatic discharge assembly allows the rice in the washing drum to be discharged quickly, effectively reducing the complexity of manual operation. Furthermore, after rapid discharge, the device can quickly prepare for the next round of cleaning, further improving production efficiency. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1 to 4 The present invention includes a washing drum 1, a partition 5 integrally formed at one end inside the washing drum 1, a feeding structure installed on the outer wall of the washing drum 1 below the partition 5, a cage-type high-pressure vortex water curtain assembly 6 rotatably installed at the center of the bottom end of the partition 5, and a rotary joint 4 installed at the center of the top end of the washing drum 1. The bottom end of the rotary joint 4 is connected to the top end of the cage-type high-pressure vortex water curtain assembly 6. The rotary joint 4 is used to realize fluid transportation, so that the cage-type high-pressure vortex water curtain assembly 6 maintains the smooth flow of external water while rotating, thereby obtaining stable water pressure and flow rate and ensuring uniform cleaning effect.

[0030] A driven rice slurry 7 is rotatably installed at the bottom edge of the partition 5 on one side of the cage-type high-pressure vortex water curtain assembly 6. A sprocket drive assembly 8 for driving the cage-type high-pressure vortex water curtain assembly 6 and the driven rice slurry 7 to rotate is installed on the back of the washing drum 1.

[0031] Among them, the outer wall of the washing drum 1 below the feeding structure is equipped with an upper and lower stepped drainage structure 9 for filtering rice and discharging waste liquid, and the outer wall of the other side of the washing drum 1 is equipped with a flip-gate pneumatic discharge assembly 3 for discharging rice material at the bottom of the washing drum 1.

[0032] The staff can install a control panel on the outer wall of the washing drum 1 via a bracket. The control panel is electrically connected to the input end of the flap-type pneumatic discharge assembly 3, the upper and lower stepped liquid discharge structure 9, and the sprocket drive assembly 8. The staff can then control the liquid discharge, material discharge, and the rotation speed of the cage-type high-pressure vortex water curtain assembly 6 and the driven rice slurry 7 during the washing process via the control panel.

[0033] The feeding structure is a feeding chute 2 installed on the outer wall of one side of the washing drum 1. The discharge part of the feeding chute 2 is located below the partition plate 5. The feeding chute 2 and the upper and lower stepped liquid discharge structure 9 are located on the same side.

[0034] The sprocket drive assembly 8 includes a motor 801 mounted on the back of the washing drum 1, a sprocket transmission structure 802 mounted on the output shaft of the motor 801, and a three-gear transmission structure 803 for connecting the cage-type high-pressure swirling water curtain assembly 6 and the driven rice slurry 7.

[0035] Example 2, based on Example 1, is... Figure 5 , Figure 3 and Figure 7 The cage-type high-pressure vortex water curtain assembly 6 includes an upper liquid inlet head 601 rotatably installed at the center of the partition plate 5, a hollow riser 603 installed at the bottom of the upper liquid inlet head 601, a lower liquid storage head 602 installed at the bottom of the hollow riser 603, and a number of C-shaped nozzles 604 arranged in a ring array between the outer walls of the hollow riser 603 and the lower liquid storage head 602. The outer wall of the C-shaped nozzles 604 is provided with a number of equally spaced spray holes 605 along the Z-axis direction. The driven rice slurry 7 is connected to the upper liquid inlet head 601 through a three-gear transmission structure 803. The top of the upper liquid inlet head 601 is fixedly connected to the bottom of the liquid outlet pipe of the rotary joint 4. The top of the upper liquid inlet head 601 is integrally formed with a number of equally spaced arc-shaped ribs 6011, and a gap 6012 is provided between two adjacent arc-shaped ribs 6011.

[0036] The C-type nozzle 604 is made of stainless steel and is 1.5 to 2 meters long. After clean water enters the upper inlet head 601, hollow vertical pipe 603, and lower storage head 602, the clean water enters the C-type nozzle 604 through the gap 6012 between two adjacent arc-shaped ribs 6011. Then, the water flows through several vertical spray holes 605 and sprays them one by one onto the rice in the washing drum 1, thereby generating several high-pressure water jets to powerfully wash the rice. At this time, the high-pressure water jets effectively remove impurities and dirt from the surface of the rice, ensuring the cleanliness of the rice and improving product quality.

[0037] The three-gear transmission structure 803 consists of a primary gear, a secondary gear shaft, and a tertiary gear ring. The primary gear is mounted on the top of the driven rice slurry turner 7, the secondary gear shaft is rotatably mounted on one side edge of the top of the partition plate 5, and the tertiary gear ring is fixed to one end of the surface of the upper liquid inlet head 601. The primary gear, secondary gear shaft, and tertiary gear ring mesh sequentially. The motor 801 drives the driven rice slurry turner 7 and the primary gear to rotate through the sprocket transmission structure 802. When the sprocket drive assembly 8 is working, the rotational power of the motor 801 is transmitted through the sprocket transmission structure 802. The power is transmitted from the structure 802 to the three-gear transmission structure 803, which in turn drives the cage-type high-pressure vortex water curtain assembly 6 and the driven rice slurry 7 to rotate, thereby driving the rice to tumble and stir inside the washing drum. The coordinated use of the motor 801, the sprocket transmission structure 802, and the three-gear transmission structure 803 can provide a stable power output to the cage-type high-pressure vortex water curtain assembly 6 and the driven rice slurry 7, ensuring that the rice is evenly tumbled during the washing process, increasing the contact area with the water flow, and thus improving the washing effect.

[0038] The sprocket drive structure 802 includes a drive sprocket mounted on the top of the output shaft of the motor 801, a driven sprocket fixed to one end of the surface of the driven rice slurry 7, and a chain installed between the driven sprocket and the drive sprocket. The driven rice slurry 7 is used to assist in turning the rice, ensuring that the rice is turned evenly during the washing process and avoiding blind spots in the washing process.

[0039] In the three-gear transmission structure 803, the first-stage gear, the second-stage gear shaft, and the third-stage gear ring mesh sequentially. That is, the output shaft of the motor 801 drives the driven rice slurry 7 and the first-stage gear to rotate through the sprocket transmission structure 802. Then, the driven rice slurry 7 and the first-stage gear drive the upper liquid inlet head 601, the hollow riser 603, and the lower liquid storage head 602 to rotate through the second-stage gear shaft and the third-stage gear ring. At this time, the rotary joint 4 continuously supplies clean water into the upper liquid inlet head 601, the hollow riser 603, and the lower liquid storage head 602.

[0040] The flip-gate pneumatic discharge assembly 3 includes a cylinder platform 301 installed on one side of the outer wall of the washing drum 1, a cylinder 302 hinged to the bottom of the cylinder platform 301, and an end plate 303 fixed on one side of the outer wall of the washing drum 1. A bent arm 304 is hinged to one end of the end plate 303 away from the washing drum 1. The end of the bent arm 304 away from the washing drum 1 is hinged to the bottom end of the piston rod of the cylinder 302 through a fish-eye joint. A gate plate 305 is hinged to the other end of the bent arm 304. The gate plate 305 is located below the lower liquid storage head 602.

[0041] During discharge, the piston rod of cylinder 302 drives the bent arm 304 to deflect around end plate 303 through the fisheye joint, and then the gate 305 is flipped, so that the bottom of the washing drum 1 presents an opening for rice material discharge, so that the washed rice can be quickly discharged after washing; the flip-gate pneumatic discharge assembly 3 opens quickly and discharges rice rapidly, improving production efficiency, reducing waiting time, and making it easy for operators to discharge materials, reducing the complexity of manual operation.

[0042] Example 3, based on Example 2, by Figure 5 and Figure 8 The upper and lower stepped drainage structure 9 is provided to discharge the sewage and impurities generated during the cleaning process in a timely manner. The upper and lower stepped design reduces the resistance of liquid flow and reduces the risk of blockage of the drainage pipe. The upper and lower stepped drainage structure 9 includes a collection pipe 901 set below the feed chute 2, an upper solenoid valve 902 and a lower solenoid valve 903 installed on the outer wall of the collection pipe 901 near the washing drum 1, and a drainage pipe 904 installed at the end of the upper solenoid valve 902 and the lower solenoid valve 903 away from the collection pipe 901. The end of the drainage pipe 904 extends into the interior of the washing drum 1 and is equipped with a filter plate 905.

[0043] When the waste liquid in the washing drum 1 is discharged using the upper and lower stepped drainage structure 9, the operator opens the upper solenoid valve 902 and the lower solenoid valve 903, so that they are in the normally open state. Then, the wastewater in the upper and lower layers of the washing drum 1 is discharged through the drainage pipes 904 at the upper and lower positions, and flows into the collection pipe 901 through the upper solenoid valve 902 and the lower solenoid valve 903 and is discharged. During this process, the filter plate 905 installed at the end of the drainage pipe 904 away from the collection pipe 901 is used to block the rice from flowing out and to allow the waste liquid to pass through.

[0044] Example 4, based on Example 2, by Figure 9 It is provided that four equally spaced sector-shaped discs with internally threaded protrusions are installed on the inner wall of the upper liquid inlet head 601, and the I-shaped hollow pipe head at the upper end of the hollow riser 603 is bolted to the internally threaded protrusions at the upper end of the sector-shaped discs, so that the hollow riser 603 and the upper liquid inlet head 601 have a bolted quick-release structure based on bolts and sector-shaped discs, so as to facilitate the disassembly and assembly of 6 by the staff and subsequent inspection and maintenance.

[0045] When the upper end of the hollow riser 603 and the lower end of the upper liquid inlet head 601 are being disassembled and assembled, the flip-gate pneumatic discharge assembly 3 needs to be in the normally open state. Furthermore, in order to facilitate the workers to tighten the bolts at the connection between the hollow riser 603 and the upper liquid inlet head 601, the workers can also make hollow parts on the front and rear outer walls of the washing drum 1 that correspond to the height of the upper liquid inlet head 601, so that the wrench can easily enter the connection position of the hollow riser 603 and the upper liquid inlet head 601.

[0046] After the hollow riser 603 and the upper liquid inlet head 601 are disassembled, the hollow riser 603, the lower liquid storage head 602 and several C-shaped nozzles 604 can be taken out of the washing drum 1 together.

[0047] When using this embodiment, the entire cleaning device first needs to be inspected, including the washing drum 1, feed chute 2, rotary joint 4, sprocket drive assembly 8, cage-type high-pressure cyclone water curtain assembly 6, driven rice slurry turning 7, upper and lower stepped liquid discharge structure 9, and gate-type pneumatic discharge assembly 3. Ensure all components are operating normally, without leaks or abnormal noise, and check the water and power supply for proper functioning. During this process, the inlet of the rotary joint 4 needs to be connected to an external water pump via a water pipe. The external water pump then delivers clean water at high pressure through the water pipe and rotary joint 4 into the cage-type high-pressure cyclone water curtain assembly. In the cage-type high-pressure cyclone water curtain assembly 6, after confirming that the device is functioning normally, the rice to be washed is fed into the washing drum 1 through the feed chute 2. During this process, care should be taken to control the feeding speed to avoid excessive rice and overloading of the device. The rice level should be between one-third and two-thirds of the height of the washing drum 1. While feeding, the operator starts the high-pressure water pump and adjusts the flow and pressure of the clean water to ensure that the cage-type high-pressure cyclone water curtain assembly 6 generates sufficient water flow for washing. Once the rice and clean water are ready, the operator starts the sprocket drive assembly 8 in the device to operate. The sprocket drive assembly 8 drives the driven agitator. The rice slurry 7 and the cage-type high-pressure vortex water curtain assembly 6 rotate, causing the rice in the washing drum to tumble and agitate. The cage-type high-pressure vortex water curtain assembly 6 also sprays high-pressure water onto the rice pile during its rotation. During the washing process, the operator observes the washing effect to ensure the water flow is evenly sprayed to every corner, avoiding blind spots. During the washing process, old wastewater and impurities are discharged through the upper and lower stepped drainage structure 9 to ensure the water quality remains clean. In the final washing cycle, the rice in the washing drum 1... During the rice feeding process, the rotary joint 4 and the cage-type high-pressure vortex water curtain assembly 6 continuously supply clean water until the clean water covers the rice and the water volume meets the requirements of the next cooking process. At this time, the upper and lower stepped drainage structure 9 is in a normally closed state to prevent the clean water from flowing out. After the clean water is completely injected, the flap gate pneumatic discharge assembly 3 is opened to discharge the clean water and rice together for use by the subsequent cooking equipment. After the discharge is completed, the staff cleans and maintains the device, especially the washing drum 1 and the upper and lower stepped drainage structure 9, to ensure that there is no residual rice or dirt for the next use.
