Description

Technical Field

[0001] The utility model relates to the technical field of oyster shell crushing and post-processing classification equipment, in particular to an oyster shell particle classifier, which can classify and screen materials and clear blocked materials. Background Art

[0002] Ring roller crushing equipment is the most commonly used device for oyster shell crushing. It mainly includes a shell, a ring roller grinder arranged on the bottom side of the shell, and a classifier arranged on the upper part of the shell. The ring roller grinder is used to crush the fed oyster shell material step by step, and then the crushed material is pumped out to the external powder collection equipment through gas extraction for collection. With the intervention of the classifier, the material that has not been crushed in place falls back to the ring roller grinder mechanism for re-crushing.

[0003] The existing oyster shell particle classifier mainly includes an exhaust pipe and an isolation cover arranged at the bottom of the exhaust pipe. The isolation cover is driven by a corresponding grading motor. The crushed material is directly extracted outward through the filter holes of the isolation cover, while the material that is not crushed is thrown out under the action of centrifugation and falls back to the ring roller abrasive mechanism for re-crushing. In the actual use of such an oyster shell particle classifier, there is a problem that is difficult to solve. The material that is not crushed is easy to form a blockage at the filter holes of the isolation cover. Since it is extremely difficult to set up a corresponding blockage clearing mechanism for the isolation cover during the rotation process, it is impossible to clear the material blocked on the isolation cover in time, which in turn affects the normal operation of the equipment. In many cases, the machine can only be shut down and the blockage can be cleared manually, which is very troublesome.

[0004] Therefore, the research purpose of this utility model is to design an oyster shell particle classifier that can effectively and automatically clear the materials blocked on the isolation cover in a timely manner without affecting the classification effect of the materials.

DETAILED DESCRIPTION

[0026] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0027] refer to Figure 1-6 , an oyster shell particle classifier, comprising:

[0028] The material extraction mechanism includes an exhaust pipe 2 connected to the top center of the corresponding pulverizer housing 1, and the exhaust pipe 2 is connected to an external exhaust fan;

[0029] The grading mechanism includes a grading motor 3 fixed to the top of the exhaust pipe 2. The output shaft end of the grading motor 3 is connected to a transmission shaft 4 extending to the lower side of the air inlet end of the exhaust pipe 2. A group of corresponding grading disks 5 are fixed to the transmission shaft 4 according to their height. The grading disk 5 located on the upper side is provided with a plurality of corresponding feeding holes 501. A plurality of corresponding isolation rods 6 are fixed between the peripheries of the grading disks 5, and adjacent isolation rods 6 are respectively arranged at intervals.

[0030] The blockage cleaning mechanism includes an iron pushing rod 8 which is laterally movably installed between two adjacent isolation rods 8 through an elastic member 7. The outer ends of the iron pushing rod 8 are respectively provided with pointed portions which can penetrate the gap between the two adjacent isolation rods 7. A corresponding electromagnet 9 is installed on the top of the shell 1 in a liftable manner. The electromagnet 9 is driven by a corresponding lifting drive mechanism 10. After the lifting drive mechanism 10 drives the electromagnet 9 downward, the electromagnet 9 is energized to form an adsorption force on the iron pushing rod 8 to drive the pointed portion of the iron pushing rod 8 to penetrate the gap between the two adjacent isolation rods 6 to clean the material stuck between the two adjacent isolation rods 6.

[0031] The present invention is additionally provided with a material blockage cleaning mechanism, which comprises an iron push rod 8 that is laterally movably installed between two adjacent isolation rods 6 via an elastic member 7, and the outer ends of the iron push rod 8 are respectively provided with a pointed portion that can penetrate the gap between the two adjacent isolation rods 6. During use, the electromagnet 9 can be regularly driven downward and energized by the lifting drive mechanism 10 to form an adsorption force on the iron push rod 8 that rotates through the position of the electromagnet 9, so as to drive the pointed portion of the iron push rod 8 one by one to penetrate the gap between the two adjacent isolation rods 6, thereby cleaning the material stuck between the two adjacent isolation rods. In this way, the material blocked on the isolation cover can be effectively and automatically cleared in a timely manner without affecting the grading effect of the material, thereby effectively ensuring the normal progress of the crushing and grading process.

[0032] After the transmission shaft 4 rotates at least one circle, the electromagnet 9 can be driven upward and reset and the power can be cut off through the lifting drive mechanism 10, so that the material between the two adjacent isolation rods 6 can be cleaned and the setting of the electromagnet 9 can be prevented from affecting the extraction process.

[0033] The transmission shaft 4 is fixedly connected to a group of corresponding guide sleeves 11 at positions corresponding to the iron pushing rod 8, and corresponding guide shafts 12 are respectively installed on the guide sleeves 11 in a transversely movably manner. The elastic member 7 is fixed between the guide sleeves 11 and the guide shafts 12, and the iron pushing rod 8 is fixed to the corresponding guide shafts 12.

[0034] The outer ends of the guide sleeves 11 are respectively fixed inwardly with corresponding elastic member mounting ring plates 13, and the inner ends of the guide shafts 12 are respectively provided with corresponding guide protrusions 14. The elastic member 7 is a coil spring, and the elastic member 7 is sleeved between the guide protrusions 14 and the elastic member mounting ring plates 13.

[0035] Through the intervention of the guide sleeve 11, the guide shaft 12, the elastic member mounting ring plate 13, the guide protrusion 14, and the coil spring 7, the movable installation of the iron push rod 8 can be effectively achieved while ensuring the structural stability, thereby effectively ensuring the practical effect of the present invention.

[0036] The lifting drive mechanism 10 uses a lifting drive cylinder, which is connected to an external pneumatic control system.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
