Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically to a filtering device for grain grinding juice. Background Technology

[0002] In the field of grain processing technology, filtering the juice from grain milling is a crucial step. The juice produced after grain milling often contains a large number of impurities, such as grain particles and fibers. If these impurities are not effectively filtered, they will seriously affect the quality and taste of the grain mill juice, and may even adversely affect subsequent processing steps and the quality of the final product.

[0003] The inventors discovered that at least the following problems remain unresolved in existing technologies: Traditional filtration equipment often employs a static filtration method, where the ground juice is directly poured into the filter screen. This method easily leads to impurities in the ground juice accumulating on one side of the filter screen, causing blockages, reducing filtration efficiency, and even requiring frequent cleaning or replacement of the filter screen, increasing production costs and operational complexity. While filter screen cleaning mechanisms are available on the market, these mechanisms are prone to interference with the filter screen's vibration mechanism, resulting in limited effectiveness.

[0004] Therefore, we propose a filtering device for grain grinding juice that can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filtering device for grain grinding juice, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtering device for grain grinding juice, comprising a filter housing, a filter screen horizontally arranged at the upper part of the filter housing, a fixing frame fixedly connected to the outer side of the filter screen, a material guiding funnel slidably connected to the upper end of the inner side of the filter housing, material guiding holes equidistantly opened on the inner wall of the bottom end of the material guiding funnel, and an adjustment structure for adjusting the filtering position of the grinding juice, and a driving mechanism for driving the filter screen to vibrate.

[0007] As an optional solution to the technical solution of this application, the adjustment mechanism includes a servo motor and a connecting sleeve. The connecting sleeve horizontally penetrates the middle of the lower end of the filter housing and is fixedly connected to the filter housing. A lead screw is fixedly connected to the shaft end of the servo motor, and the lead screw is threadedly connected to the connecting sleeve.

[0008] As an optional solution to the technical solution of this application, the driving mechanism includes a cam and an adjusting block. Limiting blocks are fixedly installed on the middle of the front and rear sides and the left and right sides of the fixed frame. Limiting grooves are vertically opened on the inner walls of the front and rear sides and the left and right sides of the filter housing. The four sets of limiting blocks on the outside of the fixed frame are slidably connected to the four sets of limiting grooves on the inner wall of the filter housing. A positioning block is fixedly installed on the side of the filter housing away from the servo motor. A spring is provided above the positioning block. The end of the lead screw away from the servo motor is fixedly connected to the cam. The bottom end of the adjusting block is fixedly connected to the upper surface of a set of the limiting blocks. The top end of the adjusting block abuts against the outside of the cam.

[0009] As an optional solution to the technical solution of this application, the positioning block has a vertically penetrating and slidably connected limit rod in the middle, the top end of the limit rod is fixedly connected to the bottom side of the limit block, and the spring is sleeved on the outside of the limit rod.

[0010] As an optional solution to the technical solution of this application, the material guide hole is placed above the filter screen, and the size of the material guide funnel is matched with that of the filter screen, and a discharge pipe is installed through the middle of the bottom end of the filter housing.

[0011] As an optional solution to the technical solution of this application, the servo motor is fixedly connected to the upper part of one side of the filter housing, and the lead screw is rotatably connected to both sides of the filter housing through bearings.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By controlling the servo motor to work, the lead screw and connecting sleeve can drive the guide funnel to move back and forth on the upper side of the inner side of the filter housing, thereby adjusting the position of the guide funnel and making the grinding juice discharged from the guide funnel evenly distributed on the surface of the filter screen, avoiding the accumulation of impurities in the grinding juice on one side of the filter screen, which would affect the filtration effect of the filter screen. At the same time, the lead screw can drive the cam to rotate. Through the combination of the adjusting block, spring and positioning block, the cam can cause the filter screen inside the fixed frame to vibrate during the reciprocating rotation, further improving the filtration effect of the filter screen on the grinding juice.

[0017] Please see Figures 1-2 This utility model provides a technical solution: a filtering device for grain grinding juice, including a filter housing 1, a filter screen 11 horizontally arranged at the upper part inside the filter housing 1, a fixing frame 12 fixedly connected to the outer side of the filter screen 11, a guide funnel 13 slidably connected to the upper end of the inner side of the filter housing 1, and also includes an adjustment structure for adjusting the filtering position of the grinding juice, and a driving mechanism for driving the filter screen 11 to vibrate. The adjustment mechanism includes a servo motor 17 and a connecting sleeve 15. The connecting sleeve 15 horizontally passes through the middle of the lower end of the filter housing 1 and is fixedly connected to the filter housing 1. A lead screw 16 is fixedly connected to the shaft end of the servo motor 17. The lead screw 16 is threadedly connected to the connecting sleeve 15. The servo motor 17 is fixedly connected to the upper side of one side of the filter housing 1, and the lead screw 16 is rotatably connected to both sides of the filter housing 1 through bearings.

[0018] In this technical solution, the servo motor 17 is controlled by a corresponding controller to drive the lead screw 16 to rotate. The lead screw 16 is threadedly connected to the connecting sleeve 15 at the lower end of the guide funnel 13. The guide funnel 13 is slidably connected to the filter housing 1. During the rotation of the lead screw 16, the guide funnel 13 can be driven to move back and forth left and right above the inner side of the filter housing 1, which can adjust the position of the guide funnel 13. The grinding juice discharged from the guide hole 14 at the bottom of the guide funnel 13 is evenly distributed on the surface of the filter screen 11, so as to avoid impurities in the grinding juice from accumulating on one side of the filter screen 11 and affecting the filtration effect of the filter screen 11.

[0019] In this embodiment, the drive mechanism includes a cam 2 and an adjusting block 26. Limiting blocks 21 are fixedly installed on the front and rear sides and the middle of the left and right sides of the fixed frame 12. Limiting grooves 22 are vertically opened on the inner walls of the front and rear sides and the left and right sides of the filter housing 1. The four sets of limiting blocks 21 on the outside of the fixed frame 12 are slidably connected to the four sets of limiting grooves 22 on the inner wall of the filter housing 1. A positioning block 24 is fixedly installed on the side of the filter housing 1 away from the servo motor 17. A spring 23 is provided above the positioning block 24. A limiting rod 25 is vertically passed through and slidably connected in the middle of the positioning block 24. The top of the limiting rod 25 is fixedly connected to the bottom side of the limiting block 21. The spring 23 is sleeved on the outside of the limiting rod 25. The end of the lead screw 16 away from the servo motor 17 is fixedly connected to the cam 2. The bottom end of the adjusting block 26 is fixedly connected to the upper surface of a set of limiting blocks 21. The top of the adjusting block 26 abuts against the outside of the cam 2.

[0020] In this technical solution, as the lead screw 16 drives the guide funnel 13 to move left and right inside the filter housing 1, it can drive the cam 2 to rotate back and forth. When the convex end of the cam 2 rotates and abuts against the top of the adjusting block 26, it slides through the limiting block 21 on the outside of the fixed frame 12 and the limiting groove 22 on the inner wall of the filter housing 1. The adjusting block 26 can push the filter screen 11 inside the fixed frame 12 to move downward. When the convex end of the cam 2 rotates away from the adjusting block 26, the elastic force of the spring 23 on the bottom side of the limiting block 21 can push the filter screen 11 inside the fixed frame 12 to move upward. Furthermore, the reciprocating rotation of the cam 2 can make the filter screen 11 inside the fixed frame 12 vibrate, further improving the filtration effect of the filter screen 11 on the ground juice.

[0021] In this embodiment, the bottom inner wall of the material guiding funnel 13 is provided with material guiding holes 14 at equal intervals. The material guiding holes 14 are placed above the filter screen 11, and the size of the material guiding funnel 13 matches that of the filter screen 11. A discharge pipe 18 is installed through the middle of the bottom of the filter housing 1.

[0022] In this technical solution, the grinding juice in the feeding funnel 13 can be evenly discharged to the surface of the filter screen 11 through the feeding holes 14 equidistantly opened at the bottom of the feeding funnel 13. Opening the valve inside the discharge pipe 18 can discharge the grinding juice filtered by the filter screen 11.

[0023] When using a grain grinding juice filtration device, a servo motor 17 is controlled by a corresponding controller to drive the lead screw 16 to rotate. The lead screw 16 is threadedly connected to the connecting sleeve 15 at the lower end of the guide funnel 13, and the guide funnel 13 is slidably connected to the filter housing 1. During the rotation of the lead screw 16, the guide funnel 13 can move back and forth left and right above the inner side of the filter housing 1, thereby automatically adjusting the position of the guide funnel 13. Through the guide holes 14 evenly spaced at the bottom of the guide funnel 13, the grinding juice in the guide funnel 13 can be evenly discharged to the surface of the filter screen 11 for filtration, preventing impurities in the grinding juice from accumulating on one side of the filter screen 11 and affecting the filtration effect of the filter screen 11. Meanwhile, the lead screw 16 can drive the cam 2 to rotate back and forth. When the convex end of the cam 2 rotates and abuts against the top of the adjusting block 26, it slides through the limiting block 21 on the outside of the fixed frame 12 and the limiting groove 22 on the inner wall of the filter housing 1. The adjusting block 26 can push the filter screen 11 inside the fixed frame 12 to move downward. When the convex end of the cam 2 rotates away from the adjusting block 26, the elastic force of the spring 23 on the bottom side of the limiting block 21 can push the filter screen 11 inside the fixed frame 12 to move upward. The cam 2 rotates back and forth, which can make the filter screen 11 inside the fixed frame 12 vibrate, further improving the filtration effect of the filter screen 11 on the grinding juice. Opening the valve inside the discharge pipe 18 can discharge the grinding juice filtered by the filter screen 11.
