Description

Technical Field

[0001] The utility model relates to the technical field of grading screens, in particular to a grading screen which is convenient for cleaning and recycling. Background Art

[0002] In the process of feed production, it is necessary to clean out the mixed flour and material blocks in the finished product. Impurities refer to large particles or small particles that do not meet the requirements. Impurities in the liquid must be filtered out, and a pile of materials must be graded and processed. According to the particle size segment, the materials are divided into multiple specifications for reuse. In order to improve the screening efficiency and effect, multi-stage screening equipment will be used to process it.

[0003] When using traditional multi-stage screening equipment, the material is first poured onto the first screen. After a certain amount has been poured out, the waste screened by the first screen will slide along the surface of the first screen into the waste bin, and the remaining material will fall on the surface of the second screen. After another screening, the coarse material with larger particles will enter the coarse material bin along the surface of the second screen, and then the fine material will fall from the holes of the second screen into the fine material bin, thereby realizing the graded recycling of the material. However, it was found in actual use that when the staff was pouring the material, they only observed it with the naked eye and then poured the material onto the screen. At this time, the amount of material was difficult to control. When too much was poured, it would cause material accumulation and increase the workload of the screening equipment, affecting the use effect and work efficiency of the screening equipment.

When the screen body 1 is used for screening and recycling of feed materials, the materials are first poured into the feed hopper 81, and then the screen body 1 is started to make the screen body 1 run, and the vibration motor 2 is started for use, and at this time, the servo motor 82 on one side of the feed hopper 81 is started, and the rotation of the servo motor 82 will drive the connecting rope 84 on the winding disk 83 to extend, thereby making the feed hopper 8 The cover plate 85 on 1 rotates and opens the bottom of the feed hopper 81 to an appropriate size. At this time, the material will be dumped onto the first screen 4. After a certain amount is poured out, the above operation is repeated, and the cover plate 85 is closed to suspend the material dumping. At this time, the waste screened by the first screen 4 will fall into the waste bin 10, and the rest will fall on the second screen 5. Then, after another screening, the coarse material with larger particles will enter the coarse material bin 6 along the surface of the second screen 5, and then the fine particles will fall from the holes of the second screen 5 into the fine material bin 7, thereby realizing the graded recycling of the material. At this time, when the screening device is in use, the material can be dumped more reasonably and efficiently for screening, thereby being more suitable for the power use of the screening device, not easily causing excessive accumulation of materials, and improving the use effect and work efficiency of the screening device.

The two side surfaces of the feed hopper 81 are respectively fixedly connected with protective plates 88, and the cross-section of one side of the protective plate 88 is arc-shaped. Through the setting of the protective plate 88, the material in the feed hopper 81 is more concentratedly poured onto the surface of the first screen 4 when pouring, and it is not easy for the material to be dispersed and leaked out of the screen body 1.

The rotation of the servo motor 82 will drive the connecting rope 84 on the winding disk 83 to extend, thereby causing the cover plate 85 on the feed hopper 81 to rotate, and open the bottom of the feed hopper 81 to an appropriate size. At this time, the material will be poured onto the first screen 4. After a certain amount of material has been poured out, repeat the above operation, close the cover plate 85 to pause the material. The material is dumped, and the waste material screened by the first screen 4 will fall into the waste bin 10, and the rest will fall on the second screen 5. Then, after another screening, the coarse material with larger particles will enter the coarse material bin 6 along the surface of the second screen 5, and then the fine material will fall from the holes of the second screen 5 into the fine material bin 7, thereby realizing the graded recycling of the material. At this time, when the screening device is in use, it can dump the material for screening more reasonably and efficiently, so as to be more suitable for the power use of the screening device, and it is not easy to cause excessive accumulation of materials, thereby improving the use effect and work efficiency of the screening device.
