[0002] A large amount of water is used in the rice processing process. Wetting softens the paddy rice, making it easier to husk and increasing the rice yield. Washing removes impurities and plant preservatives, including various substances such as rice husks and fine sand. Given the large amount of water used in rice processing, it is necessary to thoroughly filter the water to facilitate recycling and reuse, thus improving the utilization rate of water resources.

[0003] In the existing technology, when using a filter screen to filter impurities, rice contains a lot of impurities, the filter screen has a high filtration pressure, and the filter screen is very prone to clogging. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic drainage structure for rice processing equipment. This automatic drainage structure can separate impurities according to their density by diverting the flow, and collect different impurities separately to achieve a filtration effect, reduce the filtration pressure of the filter screen, and reduce the occurrence of clogging.

[0009] Water is introduced through the inlet until the water level inside the shell is higher than the diversion vertical baffle and the upper horizontal baffle, and then water is discharged through the outlet.

[0010] Preferably, the upper and lower ends of the diversion vertical baffle are flush with the upper horizontal baffle and the lower horizontal baffle, respectively. The filter screen includes an upper filter screen and a lower filter screen. The side of the upper filter screen is fixedly connected to the diversion vertical baffle, the upper horizontal baffle and the side wall of the housing.

[0031] Combination Figures 1 to 5 As shown, the automatic drainage structure of a rice processing equipment provided by this utility model includes a shell 1, a filter screen 2, a water inlet 31, and a water outlet 32.

[0032] Combination Figures 1 to 5 As shown, the housing 1 is provided with a diversion vertical baffle 11, an upper horizontal baffle 12, and a lower horizontal baffle 13. The two sides of the diversion vertical baffle 11 are fixedly connected to the inner wall of the housing 1. The upper horizontal baffle 12 and the lower horizontal baffle 13 are distributed vertically and vertically on one side of the diversion vertical baffle 11. The sides of the upper horizontal baffle 12 and the lower horizontal baffle 13 away from the diversion vertical baffle 11 are integrally formed and connected to the side wall of the housing 1. The filter screen 2 is fixedly assembled between the upper horizontal baffle 12 and the lower horizontal baffle 13. There is an inlet 31 and an outlet 32. The inlet 31 is opened on the side wall of the housing 1 near the diversion vertical baffle 11, and the outlet 32 ​​is opened on the side wall of the housing 1 between the upper horizontal baffle 12 and the lower horizontal baffle 13. Water enters through the inlet 31 until the water level in the housing 1 is higher than the diversion vertical baffle 11 and the upper horizontal baffle 12, and then water exits through the outlet 32.

[0033] In this embodiment, the flow is diverted by the vertical baffle 11. Impurities with lower density float to the surface and are concentrated above the upper horizontal baffle 12 under the action of the water flow, while impurities with higher density sink to the surface and are concentrated below the lower horizontal baffle 13 under the action of the water flow. This process removes a large number of impurities, and the filtration pressure of the filter screen 2 located between the upper horizontal baffle 12 and the lower horizontal baffle 13 decreases, thus reducing the probability of filter screen clogging.

[0034] In some embodiments, combined with Figure 2As shown, the upper and lower ends of the diversion vertical baffle 11 are flush with the upper horizontal baffle 12 and the lower horizontal baffle 13, respectively. The filter screen 2 includes an upper filter screen 21 and a lower filter screen 22. The side of the upper filter screen 21 is fixedly connected to the diversion vertical baffle 11, the upper horizontal baffle 12 and the side wall of the housing 1. The side of the lower filter screen 22 is fixedly connected to the diversion vertical baffle 11, the lower horizontal baffle 13 and the side wall of the housing 1. The impurities above the upper horizontal baffle 12 are mostly of lower density, and the impurities are not easily accumulated by filtering through the lower filter screen 21. The impurities below the lower horizontal baffle 13 are mostly of higher density, and the impurities are not easily accumulated by filtering through the upper filter screen 22. At the same time, the upper filter screen 21 and the lower filter screen 22 can be of different specifications to deal with impurities of different properties.

[0035] In some embodiments, combined with Figure 1 , Figure 2 As shown, at least two diversion vertical baffles 11 are distributed horizontally in parallel on the housing 1. The diversion vertical baffle 11 closest to the upper horizontal baffle 12 and the lower horizontal baffle 13 is fixedly connected to the upper filter screen 21 and the lower filter screen 22. The diversion distance is increased by setting multiple diversion vertical baffles 11, which makes it easier for impurities to be diverted vertically according to density, thus ensuring the diversion effect.

[0036] In some embodiments, combined with Figure 2 As shown, a rotating wheel 41 is rotatably mounted inside the housing 1. The rotating wheel 41 is located directly above the upper horizontal baffle 12. Water baffles are uniformly and fixedly connected around the rotating wheel 41. During the rotation of the rotating wheel 41, impurities floating on the water surface are gathered to one side, avoiding the reverse diffusion of impurities and ensuring the concentration effect of impurities.

[0037] In some embodiments, combined with Figure 2 As shown, a collection groove 42 is integrally formed inside the housing 1. The collection groove 42 is located directly below the lower horizontal baffle 13. The collection groove 42 is used to collect impurities that have settled to the bottom and prevents these impurities from spreading backward through the height difference.

[0038] In some embodiments, combined with Figure 2 As shown, the bottom plate inside the housing 1 is inclined, and the bottom plate inside the housing 1 is inclined downward on the side near the collection tank 42. Because the water flow has a poor effect on carrying impurities with a higher density, the inclined surface increases the concentration effect on impurities and prevents impurities from accumulating outside the collection tank 42.

[0039] In some embodiments, combined with Figure 3 As shown, the outer shell 1 is integrally formed with a vertical channel 43, which is connected to the collection tank 42. The bottom surface of the collection tank 42 is an inclined surface that slopes towards the vertical channel 43. The operator can remove the accumulated impurities through the vertical channel 43 to ensure the continuous collection capacity of the collection tank 42.

[0040] In some embodiments, combined with Figure 4 As shown, a drain window 44 is provided on the housing 1. The drain window 44 is located directly above the upper horizontal baffle 12. A sealing door is installed inside the drain window 44. Operators can remove impurities by opening the sealing door to avoid excessive accumulation of impurities directly above the upper horizontal baffle 12. At the same time, the sealed space helps to ensure the balance of water inflow and outflow.

[0041] In some embodiments, combined with Figure 5 As shown, the inlet 31 is connected in series with an L-shaped pipe 33. The inlet 31 is located below the water level, and the water outlet direction of the inlet 31 is directly opposite the diversion vertical baffle 11. The use of the L-shaped pipe 33 can ensure the water level difference when the inlet 31 is horizontal, thus ensuring the water intake capacity. The inlet 31 being located below the water level can reduce the splashing phenomenon caused by the height difference, thereby stabilizing the water flow and ensuring the diversion effect. Being directly opposite the diversion vertical baffle 11 can prevent impurities from crossing the diversion vertical baffle 11 without being diverted.

[0042] In some embodiments, combined with Figure 5 As shown, the outlet 32 ​​is connected in series with a U-shaped pipe 34. The horizontal height of the end of the U-shaped pipe 34 away from the outlet 32 ​​is higher than the horizontal height of the inlet 31. The U-shaped pipe 34 can automatically seal after the drainage stops, ensuring the airtightness of the shell 1. At the same time, the height difference can prevent the water level in the shell 1 from dropping and affecting the diversion effect.

[0043] Working process: Water flows into the housing 1 through the inlet 31 and rushes towards the diversion vertical baffle 11. Under the obstruction of the diversion vertical baffle 11, the water flow begins to be divided. The internal impurities pass over the diversion vertical baffle 11 according to their own density under the drive of the water flow. The impurities with lower density float up and pass over from above and concentrate above the upper horizontal baffle 12, while the impurities with higher density sink down and pass over from below and concentrate below the lower horizontal baffle 13. The water flow from above flows to the filter screen 2 away from the impurities, and the water flow from below flows to the filter screen 2 away from the impurities. The water flows through the filter screen 2 and is discharged through the outlet 32.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
