Technical Field

[0001] The utility model relates to the field of rice washing devices, in particular to a rice washing device. Background Art

[0002] Glutinous rice balls are one of the representatives of traditional Chinese snacks. They are spherical foods made from glutinous rice flour. One of the raw materials of glutinous rice balls is glutinous rice flour. In the process of making glutinous rice flour, the glutinous rice needs to be washed to remove dust and possible mold on the surface of the glutinous rice.

[0003] The existing rice washing device generally uses a stirring method to wash the glutinous rice stored in the tank structure.

[0004] With regard to the above-mentioned related technologies, the existing rice washing device has the problem that the friction between the rice grains is relatively gentle when washing rice, and the mold adhered to the surface of the rice grains is not easy to be removed well during the mutual friction process. In addition, the existing tank structure is not convenient for continuous rice washing. Generally, the rice in the tank needs to be washed clean and then taken out before the subsequent batches of rice washing can be carried out. In summary, the existing rice washing device has the problem that it is not easy to fully wash the glutinous rice. Utility Model Content

[0012] The utility model is further configured such that the top end height of the annular frame is lower than the height of the water surface in the tank body.

[0013] The adoption of the technical solution is conducive to the collection of floating objects on the water surface in the tank.

[0014] The utility model is further configured that separating teeth are spaced and connected between the bottom end of the partition and the inner wall of the tank body along the length direction of the bottom of the partition.

[0015] By adopting the above technical solution, the problem of insufficient cleaning of rice grains caused by too many rice grains entering the conveying pipe in a short period of time can be avoided.

[0016] The utility model is further configured that a water inlet pipe is fixedly connected to the side wall of the tank body, and the inner diameter of the water inlet pipe is larger than the inner diameter of the drain pipe.

[0017] By adopting the above technical solution, it is easier to maintain a constant water level in the tank.

[0018] The utility model is further configured that a storage rack is fixedly connected to the outer wall of the top end of the tank body at one end close to the highest point of the inclined platform.

[0019] By adopting the technical solution, it is convenient for workers to pour rice from a rice bag or other rice containers into the tank body smoothly toward the highest point of the inclined platform.

[0020] The utility model is further configured that the annular frame is composed of multiple layers of annular bent rods of different heights connected to each other, and each layer of the multiple layers of the annular frame is parallel to each other and parallel to the top surface of the ramp.

[0021] By adopting the above technical solution, the situation in which the annular frame vibrates and pushes the rice grains in the reverse direction can be avoided.

[0023] By adopting the above technical solution, it is prevented that floating impurities in the filter are returned to the tank body under the action of water flow.

[0024] The utility model is further configured such that the volume of water flowing into the tank from the water inlet pipe in the same time is equal to the sum of the volumes of rice discharged from the rice discharge pipe and the water discharged from the discharge pipe, and the water level in the tank is lower than the top of the filter screen.

[0025] By adopting the above technical solution, the water level in the tank can be kept at a relatively constant state while the rice grains are continuously discharged, which is beneficial to cleaning the floating impurities in the tank.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model is provided with a double-layer tank structure, and a pump is provided at one end of the tank structure, and the mixture of rice and water is pumped into a pipeline by the pump. The rice grains rub against the pipe wall and collide with each other in the pipeline, and dust and mold on the surface of the rice grains are efficiently removed. The rice-water mixture is discharged from the pipeline outlet and enters the inverted cone-shaped screen, and the rice-water separation is efficiently achieved when the impact screen rotates. The cleaned rice grains are discharged from the rice discharge pipe, and the rice grains are efficiently cleaned, and the situation of mold residue on the rice grains is effectively prevented;

[0028] 2. The utility model arranges an inclined landslide structure in the tank body, arranges an annular frame structure that vibrates in the vertical direction on the landslide structure, and uses a vibration motor to drive the annular frame up and down to evenly break up the rice grains poured into the tank body, so that the rice grains can slide smoothly and evenly along the landslide to the inlet of the pump machine, effectively improving the efficiency of the pump machine for the rice-water mixture, thereby preventing the rice grains from being blocked at the bottom end of the partition;

[0029] 3. The utility model arranges a filter structure on the inner wall of the tank body. The vibration motor drives the annular frame to rise and fall, and the waves generated will beat the floating impurities in the water into the filter structure. While the up and down rise and fall of the annular frame has a dispersing effect on the rice grains, the waves generated by the movement of the annular frame can also send the floating impurities in the water into the annular filter, effectively cleaning the floating impurities in the water.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0040] The following describes an embodiment of the utility model based on its overall structure.

[0041] Embodiment 1

[0042] A rice washing device, such as Figure 1-8As shown, it includes a tank body 1, the cross section of the tank body 1 is annular, and the center is rotatably connected to an inverted cone-shaped filter cartridge 7, one end of the tank body 1 is fixedly connected to two mutually symmetrical partitions 2, specifically, the cross sections of the two partitions 2 are symmetrical to each other with the diameter of the cross section of the tank body 1 in the same plane as the symmetry axis, the bottom end of the partition 2 does not contact the inner wall of the tank body 1, and a gap is left between the bottom end of the partition 2 and the inner wall of the tank body 1 for the purpose of allowing rice grains to enter the pump 5 at a slow speed, so that the rice grains sucked by the pump 5 can be mixed in the delivery pipe 6 to form a rice-water mixture with a suitable rice content, and a pump 5 for extracting the rice-water mixture is provided between the inner sides of the two partitions 2 at the bottom end of the tank body 1. A first mounting platform 3 is fixedly connected between the two partitions 2, a first motor 4 for driving a pump 5 is mounted on the first mounting platform 3, an output end of the first motor 4 is connected to a power input shaft on the pump 5 through a transmission shaft, an output port of the pump 5 is connected to a delivery pipe 6, specifically, the delivery pipe 6 is a galvanized pipe, an inner wall of the filter cartridge 7 is provided with annularly arranged impact plates 8, an outlet of the delivery pipe 6 is inclined toward the impact plate 8 at the top of the filter cartridge 7, the rice-water mixture sprayed from the outlet of the delivery pipe 6 will rush toward the impact plate 8, thereby driving the filter cartridge 7 to rotate smoothly, a rice discharge pipe 9 is connected to the bottom end of the filter cartridge 7, and a drain pipe 11 is connected to the bottom end of the center of the tank body 1.

[0043] See also Figure 1-5 The bottom of the tank body 1 is provided with an inclined platform 12 between the outer sides of the two partitions 2. The part of the inclined platform 12 away from the partition 2 is higher than the part close to the partition 2. The rice grains poured into the tank body 1 can slide downward on the inclined platform 12 due to their own gravity, and then the rice grains in the tank body 1 away from the pump 5 can also move smoothly to the position where they can be pumped up by the pump 5, which effectively improves the efficiency of the pump 5 in extracting the mixture of rice grains and water. The top of the inclined platform 12 is arranged in a ring-shaped interval with vertically upward fixed columns 13. The multiple fixed columns 13 are slidably connected with an annular frame 14 in the vertical direction, and vertical springs are arranged in the fixed columns 13. Specifically, the annular The frame 14 is fixedly connected with a vertical sliding column, and the bottom end of the sliding column is slidably connected to the fixed column 13. The top of the annular frame 14 is connected with at least one second mounting platform 15, and a second motor 16 is installed on the second mounting platform 15. The output end of the second motor is connected with an eccentric block. When the second motor 16 is working, the eccentric block connected to its output end causes the annular frame 14 to vibrate in the vertical direction as a whole. Under the elastic force of the spring in the fixed column 13, the annular frame 14 can continue to maintain a state of up and down vibration, which plays a role in breaking up the rice grains in the tank body 1, and effectively preventing the rice grains from agglomerating after being poured into the tank body 1 and blocking the inlet of the pump 5.

[0044] See also Figure 1-4The outer wall of the top of the tank body 1 is fixedly connected with a storage rack 19 at one end near the highest point of the inclined platform 12. An open rice bag or a container containing rice grains can be temporarily placed on the storage rack 19, so that the staff can pour the rice in the rice bag or other containers containing rice into the tank body 1 smoothly toward the highest point of the inclined platform 12.

[0045] See also Figure 4-5 The top of the annular frame 14 is lower than the height of the water surface in the tank body 1, so as to avoid the top of the annular frame 14 frequently entering and exiting the water surface and splashing water, and to avoid the water in the tank body 1 spilling out from the opening on the top surface of the tank body 1. At the same time, it can also effectively avoid the top of the annular frame 14 frequently entering and exiting the water surface and generating bubbles, which is beneficial to the collection of floating objects on the water surface in the tank body 1. The annular frame 14 is composed of multiple layers of annular bent rods of different heights connected to each other. The layers of the multi-layer annular frame 14 are parallel to each other and are all parallel to the top surface of the inclined platform 12. The parallel annular frame 14 structure can better promote the rice grains to slide downward along the inclined platform 12 when vibrating up and down, and avoid the situation where the annular frame 14 vibrates and pushes the rice grains in the opposite direction.

[0046] See also Figure 1 , Figure 5 and Figure 8 The bottom end of the partition 2 and the inner wall of the tank body 1 are spaced apart and connected with partition teeth 18 along the length direction of the bottom of the partition 2. The partition teeth 18 can effectively prevent the rice grains from rushing into the inner sides of the two partitions 2 quickly, thereby preventing too many rice grains from entering the conveying pipe 6 in a short time and causing the problem of insufficient rice cleaning. The partition teeth 18 limit the rice grains from passing through the gap between the bottom end of the partition 2 and the inner wall of the tank body 1 too quickly, thereby preventing the rice grains from being contained in the rice-water mixture passing through the conveying pipe 6 too many rice grains and reducing the cleaning effect of the rice grains.

[0047] Embodiment 2

[0048] A rice washing device, such as Figure 1-8As shown, on the basis of the first embodiment, the difference from the first embodiment is that an annular filter screen 17 is fixedly connected to the inner wall of the tank body 1, and the height of the bottom end of the filter screen 17 is the same as the height of the water surface in the tank body 1 in a horizontal and calm state, so as to prevent the floating impurities in the filter screen 17 from returning to the tank body 1 under the action of the water flow. The water in the tank body 1 generates waves due to the vibration of the annular frame 14, and the waves knock the floating impurities on the water surface into the filter screen 17. Subsequently, it is only necessary to shovel out the impurities in the filter screen 17 to conveniently realize the automatic cleaning of the floating impurities on the water surface. 1 is fixedly connected to a water inlet pipe 10, the inner diameter of the water inlet pipe 10 is larger than the inner diameter of the drain pipe 11, so that the tank body 1 can more easily maintain a constant water level. The volume of water flowing into the tank body 1 from the water inlet pipe 10 in the same period of time is equal to the sum of the volumes of rice discharged from the rice discharge pipe 9 and the water discharged from the drain pipe 11. The water level in the tank body 1 is lower than the top of the filter screen 17, so that when the rice grains are continuously discharged, the water level in the tank body 1 can also be continuously maintained in a relatively constant state, which is conducive to cleaning the floating impurities in the tank body 1.

[0049] The working principle of the utility model is as follows: water is poured into the tank body 1 and the rice grains to be cleaned are poured into the highest point of the inclined platform 12, so that the water level in the tank body 1 is roughly maintained at the position of the bottom end of the filter screen 17, the second motor 16 and the first motor 4 work, and the annular frame 14 vibrates up and down to drive the rice grains in the tank body 1 to slide toward the bottom end of the partition 2 to avoid the rice grains from agglomerating in the tank body 1. At the same time, the waves generated by the up and down movement of the annular frame 14 carry the floating impurities on the water surface over the top of the filter screen 17, and the impurities are effectively collected by the filter screen 17, and the pump 5 pumps the rice grains through the bottom end of the partition 2 together with the water. The rice grains enter the conveying pipe 6, and the rice grains rub against the inner wall of the conveying pipe 6. At the same time, the rice grains in the conveying pipe 6 also rub against each other, so that the rice grains are efficiently cleaned. The mixture of the cleaned rice grains and the sewage is discharged from the output port of the conveying pipe 6, and the rice-water mixture rushes toward the impact plate 8 to rotate the filter cartridge 7. The rice-water mixture enters the filter cartridge 7 through the gap between the impact plates 8 and slides downward along the inner wall of the filter cartridge 7. Since the filter cartridge 7 is in a rotating state, the sewage is efficiently thrown out under the action of centrifugal force, and the cleaned rice grains are discharged along the rice discharge pipe 9 at the bottom of the filter cartridge 7, and the sewage is discharged from the tank body 1 along the drain pipe 11.

[0050] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
