Description

Technical Field

[0001] The utility model relates to the general field of crushing, grinding or pulverizing technology, and more specifically to an air flow grinding material taking mechanism for lithium iron phosphate processing. Background Art

[0002] Lithium iron phosphate is a lithium-ion battery electrode material, and lithium iron phosphate needs to be crushed by airflow mill during production. After the material enters the crushing chamber through the screw feeder, several relatively arranged nozzles spray out high-speed airflow impact energy, and the collision and friction generated by the rapid expansion of the airflow in the fluidized bed suspension boiling crush the material. During the crushing, sampling needs to be carried out through the material taking mechanism, which is convenient for the detection of lithium iron phosphate inside the airflow mill. The technical inspiration for the material taking mechanism was found;

[0003] At present, CN200920186032.X in the prior art discloses a material taking device for a jet mill. The utility model jet mill has an opening on the side wall of the material discharging pipe, and a material taking pipe is fixedly fitted in the opening. The open end of the material taking pipe is a material taking port, and the other end is closed, so that sampling is convenient, the particle size can be monitored at any time, and oxidation of powder can be prevented, which greatly reduces the work intensity of the operator.

[0004] The material taking mechanism takes materials through the pipeline. Since the grinding of lithium iron phosphate is not completed during the grinding process of the jet mill, the lithium iron phosphate taken out is likely to have different particle sizes. Therefore, after the material taking mechanism takes the materials, the lithium iron phosphate needs to be manually screened again to facilitate subsequent testing, which makes it impossible for the material taking mechanism to quickly screen the lithium iron phosphate during the material taking process, avoiding the removal of large particles of lithium iron phosphate.

[0005] The utility model can mainly solve the problem that the material taking mechanism cannot quickly screen the lithium iron phosphate during the material taking process. Utility Model Content

[0006] The utility model aims to solve the problem in the background, thereby providing an air flow grinding material taking mechanism for lithium iron phosphate processing.

[0012] Furthermore, both ends of the sliding rod are in the sliding groove inside the guide groove, the guide groove of the material guide groove is in a vertical arc shape, the sliding rod slides from bottom to top inside the guide groove through the sliding groove, and the connecting rod is a deformable material, such as rubber material.

[0013] Furthermore, the filter screen has a plurality of holes running through it, with a hole diameter of 0.1-0.3 cm, one end of the filter screen is connected to the outer wall of the rotating bearing, and the filter screen is movably wrapped around the outer side of the rotating bearing.

[0014] Furthermore, an opening is provided at one end of the cross bar close to the filter screen, the rotary bearing is rotatable 360 ​​degrees inside the cross bar, and the springs are located at both ends of the cross bar.

[0015] 1. When the baffle plate of the air flow grinding material taking mechanism for lithium iron phosphate processing slides upward, the baffle plate drives the sliding rod to slide through the connecting rod, and the sliding rod can slide in the sliding groove on the inner wall of the material guide groove.

Since the sliding track of the sliding rod is arc-shaped and upward, the filter screen is tilted and penetrates the inside of the guide groove as a whole, so that the lithium iron phosphate in the guide groove can be filtered through the filter screen when passing through the inside of the guide groove, so that the material taking mechanism can filter the lithium iron phosphate when taking the material, which is convenient for subsequent sampling and testing;

[0017] 3. After the baffle is manually slid downward, one end of the sliding rod cannot form an upward pulling force. Using the weight of the sliding rod, the sliding rod can slide downward inside the slide groove of the material guide trough.

[0029] Among them: the jet mill 101, the jet mill 101 is used in conjunction with a cyclone separator, a dust collector and an induced draft fan;

[0030] After the material enters the grinding chamber inside the jet mill 101, the impact energy of high-speed airflow is sprayed out by several relatively arranged nozzles, and the collision and friction force generated by the rapid expansion of the airflow and the suspension boiling of the fluidized bed grinds the material;

[0031] The guide trough 1 is hollow inside and inclined downward by 5-15 degrees;

[0032] The guide trough 1 is inclined downward by 5-15 degrees to facilitate the downward conveying and discharge of lithium iron phosphate powder;

[0035] Wherein: the lithium iron phosphate is crushed by the air flow mill 101. When the material needs to be taken out, the baffle 102 is manually slid upward, and the lithium iron phosphate powder inside the air flow mill 101 slides down through the inside of the material guide trough 1, and then the baffle 102 is manually slid downward, and the baffle 102 and the card slot are vertically nested and docked. When the baffle 102 slides into the inside of the material guide trough 1, the baffle 102 can form a seal on the inside of the material guide trough 1, thereby facilitating the taking out of the lithium iron phosphate powder inside the air flow mill 101;

[0036] Example 2: Refer to the attached manual Figure 1-7 , the difference between Example 2 and Example 1 is that a connecting rod 2 is embedded on one side of the baffle 102, a sliding rod 201 is slidably disposed on the side of the connecting rod 2 away from the baffle 102, a filter screen 202 is embedded on the side of the sliding rod 201, and sliding grooves are provided on both sides of the inner wall of the guide trough 1 close to one end of the airflow mill 101, a cross bar 3 is provided at the lower end of the sliding groove, a rotating bearing 301 is rotatably disposed inside the cross bar 3, and discs 302 are mounted on both ends of the rotating bearing 301, a spring 303 is elastically connected to the inner wall of the disc 302, and one end of the spring 303 is connected to the outer wall of the rotating bearing 301;

[0037] Wherein: the connecting rod 2 and the sliding rod 201, the two ends of the sliding rod 201 are in the sliding groove inside the sliding groove, the sliding groove of the guide groove 1 is vertically arc-shaped, the sliding rod 201 slides from bottom to top inside the guide groove 1 through the sliding groove, and the connecting rod 2 is a deformable material, such as rubber material;

[0038] The two ends of the sliding rod 201 are in the inner slide groove, and the slide groove of the guide groove 1 is vertically arc-shaped. Figure 3 As shown;

[0039] The connecting rod 2 is made of a deformable material, such as rubber, so that when the baffle 102 slides vertically, the baffle 102 can drive the sliding rod 201 to slide vertically in an arc through the connecting rod 2;

[0040] The filter screen 202 has a plurality of holes therein, the hole diameter of which is 0.1-0.3 cm. One end of the filter screen 202 is connected to the outer wall of the rotating bearing 301, and the filter screen 202 is movably wound around the outer side of the rotating bearing 301;
