Description

Technical Field

[0001] This utility model relates to the field of grain processing equipment technology, and in particular to a wheat impurity removal device. Background Technology

[0002] Wheat is a general term for plants of the genus Triticum, a cereal crop widely cultivated around the world. Wheat grains are one of the staple foods for humans. After being ground into flour, they can be used to make bread, steamed buns, biscuits, noodles and other foods. After fermentation, they can be made into beer, alcohol, spirits or biomass fuel. Currently, impurity removal devices are required in the wheat processing process.

[0003] Existing impurity removal devices have poor targeting capabilities. Most devices rely on a single screen structure, which can only separate large particles of stone or light straw that are significantly different in size from wheat grains. They are unable to effectively intercept fine impurities such as mud and dust smaller than wheat grains. These small impurities can easily penetrate ordinary screens and mix with wheat, resulting in a large amount of fine impurities remaining after removal. This fails to meet the purity requirements of subsequent processing. Furthermore, the conveying and screening processes are prone to blockages. The conveying channels from wheat inlet to screening are mostly cylindrical structures, lacking a uniform feeding mechanism. This makes it easy for wheat to accumulate and clump at the inlet or guide point. At the same time, the screen holes are easily blocked by adhered wheat or fine impurities, requiring frequent shutdowns for cleaning. This not only interrupts the operation process and reduces efficiency, but in severe cases, the accumulation can also cause equipment jams and malfunctions, increasing equipment maintenance costs.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1 Reference Figures 1-4 The first embodiment of this utility model provides a wheat impurity removal device, including a body 1, a processing chamber inside the body 1, a spiral blade 2 that penetrates the top of the body 1 and is used for pushing the material at the top of the processing chamber, and a coarse filter screen 4 that can move up and down is slidably connected to the bottom of the spiral blade 2.

[0019] An installation groove 5 is provided inside the processing cavity. A cylinder 6, which is fixedly connected to the circumference of the coarse filter screen 4, is slidably connected inside the installation groove 5. Multiple arc-shaped notches 7 are provided at the bottom end of the cylinder 6. A pulley 8, which slides in contact with the arc-shaped notches 7, is fixedly connected to the bottom end of the installation groove 5.

[0020] A fine filter 10 is slidably connected inside the processing chamber and rises and falls synchronously with the coarse filter 4. The fine filter 10 is located below the coarse filter 4. A collection box 15 is slidably connected to the bottom of the processing chamber. A corrugated pipe 12 is fixedly connected to the bottom end of the fine filter 10. A discharge pipe 11 that penetrates the machine body 1 is fixedly connected to the bottom end of the corrugated pipe 12.

[0021] The bottom end of the spiral blade 2 is provided with a groove 3, and a slider 17 is slidably connected in the groove 3. The bottom end of the slider 17 is fixedly connected to the top end of the coarse filter screen 4. The top end of the cylinder 6 is slidably in contact with an arc plate 18. A spring 19 for pushing the arc plate 18 is provided in the mounting groove 5.

[0022] During use, after placing the device stably, ensure that the impurity collection box 15 has been pushed into the bottom of the processing chamber of the machine body 1, and that the corrugated pipe 12 and the discharge pipe 11 are properly connected. The staff pours the wheat to be impurities removed into the feed pipe 16 at the top of the machine body 1. The feed pipe 16 is connected to the spiral blade 2, which can guide the wheat to fall accurately into the conveying area of ​​the spiral blade 2, avoiding the spillage of the feed.

[0023] Start the drive motor at the top of the gantry 20. The output of the drive motor drives the spiral blades 2 to rotate. During the rotation, the spiral blades 2 continuously push the wheat falling into the feed pipe 16 downward. Compared with the traditional straight cylinder feeding structure, the continuous pushing of the spiral blades 2 can effectively prevent wheat from accumulating and clumping in the conveying process, solve the conveying blockage problem from the source, and ensure that the wheat enters the screening area evenly.

[0024] A slider 17 is slidably connected in the groove 3 at the bottom of the spiral blade 2. The bottom of the slider 17 is fixed to the top of the coarse filter screen 4. Therefore, when the spiral blade 2 rotates, it will drive the coarse filter screen 4 to rotate synchronously. The cylinder 6, which is fixed on the circumference of the coarse filter screen 4, rotates with the coarse filter screen 4 in the mounting groove 5. The pulley 8 at the bottom of the mounting groove 5 slides in contact with the arc-shaped notch 7 at the bottom of the cylinder 6. When the pulley 8 rolls from the concave area to the convex area of ​​the arc-shaped notch 7, it will push the cylinder 6 to move upward. The cylinder 6 drives the coarse filter screen 4 to rise synchronously. At the same time, the top of the cylinder 6 presses against the arc plate. 18. The arc plate 18 compresses the spring 19 in the mounting groove 5, and the slider 17 slides and rises synchronously along the slide groove 3. When the pulley 8 rolls from the raised area to the concave area of ​​the next arc-shaped notch 7, the spring 19 releases its elastic potential energy to push the arc plate 18 to reset. The arc plate 18 drives the cylinder 6 and the coarse filter screen 4 to descend and reset. This process is repeated. The coarse filter screen 4 vibrates up and down while rotating, achieving a vibration screening effect. This intercepts larger impurities in the wheat on the coarse filter screen 4, avoiding the use of additional vibration components and reducing equipment purchase and maintenance costs.

[0025] Example 2 Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the coarse filter screen 4 and the fine filter screen 10 are provided with a connecting rod 9 on their circumferential surfaces to achieve synchronous lifting and lowering; the circumferential surface of the cylinder 6 is provided with an annular groove 14; one end of the connecting rod 9 near the cylinder 6 is rotatably connected to the annular groove 14; the fine filter screen 10 is inclined; a guide plate 13 is fixedly connected in the processing cavity; the guide plate 13 is located between the fine filter screen 10 and the coarse filter screen 4.

[0026] The corrugated pipe 12 is located at the lower end of the fine filter screen 10, and the bottom end of the connecting rod 9 is fixedly connected to the circumferential surface of the fine filter screen 10 on the side close to the fine filter screen 10.

[0027] A feed pipe 16 is fixedly connected to the top of the machine body 1. The feed pipe 16 is sleeved with the spiral blade 2. A gantry 20 is fixedly connected to the top of the machine body 1.

[0028] A drive motor is fixedly connected to the top of the gantry 20, and the output end of the drive motor is fixedly connected to the top of the spiral blade 2. The gantry 20 is located at the top of the feed pipe 16.

[0029] During use, wheat filtered through the coarse filter 4 falls into the flow guide plate 13 in the processing chamber. The flow guide plate 13 guides the wheat to slide precisely onto the fine filter 10 below. Since the cylindrical cylinder 6 has an annular groove 14 on its circumference, and one end of the connecting rod 9 is rotatably connected to the annular groove 14, while the other end is fixed to the circumference of the fine filter 10, when the coarse filter 4 vibrates up and down, it will drive the fine filter 10 to vibrate up and down synchronously through the cylindrical cylinder 6 and the connecting rod 9. The fine filter 10 is set at an angle, which can accelerate the flow of wheat during vibration and prevent accumulation. At the same time, it separates the fine impurities smaller than wheat grains from the wheat. The fine impurities pass through the sieve holes of the fine filter 10 and fall into the collection box 15 below for centralized collection.

[0030] A corrugated pipe 12 is fixedly connected to the bottom of the lower end of the fine filter screen 10. The corrugated pipe 12 has a telescopic characteristic, which can adapt to the up and down vibration of the fine filter screen 10 and avoid the discharge channel from breaking or blocking due to vibration. The clean wheat after being screened by the fine filter screen 10 slides down the inclined fine filter screen 10 to the lower end, enters the corrugated pipe 12, and is then discharged from the machine body 1 through the discharge pipe 11 fixedly connected to the corrugated pipe 12, thus completing the entire process of wheat impurity removal.

[0031] After the operation is completed, turn off the drive motor, pull out the impurity collection box 15 from the bottom of the processing chamber, clean the small impurities collected inside, and clean the large particles of impurities intercepted on the coarse filter screen 4 to ensure smooth screening in the next use. After cleaning, push the impurity collection box 15 back to its original position to keep the equipment clean.

[0032] The remaining structure is the same as that in Example 1.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
