Description

Technical Field

[0001] The utility model relates to the technical field of classifying and refining, in particular to a classifying device for mixed refining. Background Art

[0002] Mixed refining is an important step in the papermaking process. Grinding is the finishing process of the machined surface by using abrasive particles coated or pressed on the grinding tool through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metallic materials, and different dry and wet raw materials should be mixed and refined during use. At the same time, the raw materials will be collected according to their size during the later collection process.

[0003] In the prior art, after searching, a grinder with a graded grinding function is disclosed in the patent number CN202122055744.1.

[0004] However, when the device is working, after the material slurry is diverted from the guide groove, the grinding disc is used in conjunction with the grinding groove to perform fine graded grinding on the large particles in the material, thereby improving the grinding accuracy and ensuring the product quality; through the setting of the blowing mechanism, the fan is used to blow air into the shell, and the ground powder is blown to the end of the first discharge port, filtered again through the screening net, and the fine powder is discharged through the other end of the first discharge port, and the remaining powder is discharged through the second discharge port. By grinding the dry material and blowing air through the blowing mechanism, the work of raw material classification and collection can be completed. However, if faced with wet raw materials, the device cannot meet the needs of graded refining, so there is an urgent need for a device that can grind both dry and wet materials.

All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1-4 The utility model provides a technical solution: a grading device for mixed refining, comprising: a grinder 1, a grading box 2 is provided at the lower side of the grinder 1, an upper grading frame 3 is provided inside the grading box, a lower grading frame 4 is provided at the lower side of the upper grading frame 3, elastic columns 5 are provided on both sides of the upper grading frame 3 and the lower grading frame 4, a fixed plate 6 is fixedly connected to the upper surface of the elastic column 5, the upper surface of the fixed plate 6 is fixedly connected to one end of a buffer 7, and the other end of the buffer 7 is fixedly connected to a rubber head 8.

[0025] The upper grading frame 3 and the lower grading frame 4 are both provided with circular holes, and the diameter of the circular holes in the upper grading frame 3 is larger than that of the circular holes in the lower grading frame 4. The mixed and refined raw materials are added to the grinder 1 from the feeding pipe installed on the grinder 1, so that the raw materials are mixed and refined by the grinder 1. After grinding, the raw materials enter the grading box 2 and fall into the upper grading frame 3 first. At this time, the elastic column 5 is reciprocated up and down, so that the elastic column 5 drives the fixed plate 6 to reciprocate up and down, and then the fixed plate 6 drives the rubber head 8 up and down through the buffer 7, so that the rubber head 8 hammers the lower surfaces on both sides of the upper grading frame 3, thereby causing the upper grading frame 3 to shake, and the raw materials with smaller particles continue to fall into the lower grading frame 4 through the upper grading frame 3. Similarly, the rubber heads 8 on both sides of the lower grading frame 4 repeatedly hammer the lower grading frame 4, so that the materials with smaller particles can be separated, and the separated materials enter the receiving box 11, thereby completing the function of grading and collection.

[0026] Example 2: On the basis of Example 1, the bottom of the grinder 1 is fixedly connected to one end of the discharge pipe 9, and the other end of the discharge pipe 9 is fixedly sleeved on the top of the grading box 2. The bottom of the grinder 1 is connected to the top of the grading box 2 through the discharge pipe 9, so as to facilitate the material to enter the grading box 2. A support column 10 is provided on one side of the discharge pipe 9. The support column 10 is fixedly connected between the grinder 1 and the grading box 2. The bottom of the grading box 2 is slidably connected to the receiving box 11. The support column 10 fixedly supports the grinder 1. A guide pipe 12 is provided between the upper grading frame 3, the lower grading frame 4 and the lower grading frame 4 and the receiving box 11. The guide pipe 12 is fixedly connected to the side wall of the grading box 2. The guide pipe 12 is fixedly installed in the grading box 2 to guide the graded raw materials to avoid splashing of the raw materials. The upper grading frame 3 and the lower grading frame 4 are fixedly connected to the side walls of the grading box 2 on both sides by fixing bolts 13. A door panel 14 is provided on one side of the fixing bolt 13. The door panel 14 and the grading box 2 are hinged by a hinge. Fixed plates 15 are fixedly connected on both sides of the inner wall of the grading box 2. The upper grading frame 3 and the lower grading frame 4 are fixedly installed in the grading box 2 by the fixing bolts 13. The door panel 14 is provided on one side of the upper grading frame 3 and the lower grading frame 4, so that the upper grading frame 3 and the lower grading frame 4 can be easily taken out by opening the door panel 14.

[0027] By fixing the grading box 2 to the ground and then supporting the grinder 1 with support columns 10, it is convenient to mix and refine the raw materials through the grinder 1. After the mixing and refining is completed, the raw materials flow into the grading box 2 through the discharge pipe 9 at the bottom of the grinder 1, so that the raw materials are graded and collected by the upper grading frame 3 and the lower grading frame 4. A guide pipe 12 is provided between the upper grading frame 3, the lower grading frame 4 and the receiving box 11. The guide pipe 12 can prevent the splashing of materials during the grading process on the one hand and guide the materials on the other hand. Through holes are provided on both the upper grading frame 3 and the lower grading frame 4, and the diameter of the through holes provided on the upper grading frame 3 is larger than the diameter of the through holes provided on the surface of the lower grading frame 4, so that the raw material particles are graded. After the collection is completed, the fixing bolts 13 installed on both sides of the upper grading frame 3 and the lower grading frame 4 are removed and the door panel 14 is opened, so that the upper grading frame 3 and the lower grading frame 4 can be taken out. At the same time, the receiving box 11 can also be taken out through the sliding connection between it and the grading box 2, thereby completing the graded collection of the raw materials.

[0028] Embodiment 3: On the basis of embodiment 2, the upper surface of the fixed plate 15 is fixedly connected to the support platform 16, the lower surface of the support platform 16 is fixedly installed with a motor 17, the upper surface of the support platform 16 is fixedly connected to a sliding sleeve 18, the upper surface of the sliding sleeve 18 is fixedly connected to a limiting sleeve 19, the fixed plate 15 fixedly supports the support platform 16, and the support platform 16 fixedly supports the motor 17, the bottom of the elastic column 5 is sleeved in the sliding sleeve 18 and is slidably connected to the sliding sleeve 18, a spring 20 is fixedly connected between the lower surface of the elastic column 5 and the support platform 16, and the output end of the motor 17 passes through the support platform 16 and is connected to the sliding sleeve 18. One end of the T-shaped shaft 21 is fixedly connected, and the sliding sleeve 18 and the limiting sleeve 19 facilitate the sliding and limiting of the elastic column 5. The spring 20 is fixedly connected between the elastic column 5 and the upper surface of the support platform 16. The output end of the motor 17 passes through the top of the support platform 16 and is fixedly connected to the bottom end of the T-shaped shaft 21. The other end of the T-shaped shaft 21 is fixedly connected with a spiral piece 22. The inner ring surface of the elastic column 5 is fixedly sleeved with a sliding column 23, and the sliding column 23 is slidingly connected to the spiral piece 22. The top end of the T-shaped shaft 21 is fixedly connected with a spiral piece 22, and the spiral piece 22 is slidingly connected to the sliding column 23 fixedly sleeved in the elastic column 5.

[0029] The grinder 1 and the motor 17 are both electrically connected to the external terminal control device. The ground raw materials flow from the discharge pipe 9 into the grading box 2 and fall into the upper grading frame 3. At this time, by starting the motors 17 on both sides of the upper grading frame 3, the motor 17 drives the T-shaped shaft 21 fixedly connected to its output end to rotate under the driving action of the motor 17, and the T-shaped shaft 21 thereby drives the spiral piece 22 to rotate. Through the sliding connection between the spiral piece 22 and the slide post 23, the spiral piece 22 presses the slide post 23 to move downward, and the slide post 23 thereby drives the spring post 5 to move toward the bottom direction of the sliding sleeve 18 and the limit sleeve 19. During this process, the spring 20 is compressed. This process is a force storage process until the spiral piece 22 rotates to no longer contact the slide post 23. When the upper grading frame 3 is opened, the rubber heads 8 on both sides of the upper grading frame 3 impact the lower surfaces of the upper grading frame 3, and so on. The rubber heads 8 on both sides of the lower surface of the upper grading frame 3 repeatedly impact it, thereby screening the raw material particles. The raw materials with smaller particles pass through the upper grading frame 3 and fall into the lower grading frame 4. At this time, by starting the motors 17 on both sides of the lower grading frame 4, the rubber heads 8 on both sides of the lower grading frame 4 are repeatedly hammered, so that the materials with smaller particles continue to move downward and finally fall into the receiving box 11, thereby completing the classification and collection function.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
