Description

Technical Field

[0001] This utility model relates to the field of lithium phosphate processing technology, and more specifically, to a grinding device for lithium phosphate processing. Background Technology

[0002] Lithium phosphate is an inorganic compound with a wide range of applications. During its processing, grinding is often required. For example, application number "CN202211502995.2" proposes a grinding device for preparing battery-grade iron phosphate from waste lithium iron phosphate slag. This device includes a grinding box, fixed grinding blocks, and rotating grinding blocks. A feed hopper is fixedly connected to the left side of the upper surface of the grinding box, and a discharge port is fixedly connected to the lower surface. The fixed grinding blocks are placed on the inner wall of the grinding box via a buffer assembly. A first motor is fixedly connected to the upper surface of the grinding box, and a rotating shaft is fixedly connected to the output end of the first motor. The bottom end of the rotating shaft is located inside the grinding box and is equipped with an up-and-down adjustment assembly. This invention can simultaneously perform rotary grinding of waste lithium iron phosphate slag and compression, thereby improving the grinding quality. Furthermore, the mounting ring drives the fixed grinding blocks to reset downwards, causing the striking rod to impact the screening box, thus vibrating the screening box and preventing blockage of the screening holes, resulting in better screening of the ground iron phosphate.

[0003] However, although the above technical solutions can avoid clogging of the screening holes, the grinding box is in a semi-sealed state, which makes it very easy for the dust generated during the grinding process to be dispersed through the feed hopper and discharge port of the grinding box. This causes a large amount of fine dust to easily drift into the working environment, posing a threat to the health of operators and potentially polluting the surrounding environment and affecting the normal operation of other production equipment. Therefore, we propose a grinding device for lithium phosphate processing to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a grinding device for lithium phosphate processing, which solves the problem that although it can avoid clogging of the screening holes, the dust generated during the grinding process is very easy to drift through the feed hopper and discharge port of the grinding box because the grinding box is in a semi-sealed state. This causes a large amount of fine dust to easily drift into the working environment, posing a threat to the health of operators, and may also pollute the surrounding environment and affect the normal operation of other production equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A grinding device for lithium phosphate processing includes a grinding box. The grinding box has a first grinding groove and a second grinding groove on its upper and lower sides, respectively, with a connecting pipe running through them. A sloping groove runs through the lower end of the grinding box and is connected to the second grinding groove. A grinding mechanism is installed between the first and second grinding grooves. A feed inlet is installed at the upper end of the grinding box, with a sealing cap at its upper end. A discharge port is installed on one side of the sloping groove. A storage tank is installed on the side of the grinding box near the discharge port, and the storage tank and discharge port are vertically parallel. An annular groove is provided at the upper end of the grinding box, and this annular groove is parallel to the first grinding groove. Several liquid outlet holes run through the annular groove and the first grinding groove. A liquid injection pipe is installed through the upper side of one side of the grinding box and is connected to the annular groove.

[0007] Preferably, fixing plates are installed at the front and rear ends of the feed inlet near the injection pipe, and a fixing rod is fixedly installed between the fixing plates. The lower end of the sealing cover is movably installed between the fixing plates, and the rod body of the fixing rod is movably installed through the inside of the sealing cover. A torsion spring is installed between the sealing cover and the fixing rod.

[0008] Preferably, the grinding mechanism includes a first moving grinding block and a second moving grinding block. The first moving grinding block is movably installed inside the upper part of the second grinding tank, and a first stationary grinding block is fixedly installed inside the upper part of the second grinding tank. The first moving grinding block and the first stationary grinding block are engaged and connected.

[0009] Preferably, the second moving grinding block is movably installed inside the upper part of the first grinding tank, and the second stationary grinding block is fixedly installed inside the upper part of the first grinding tank, with the second moving grinding block and the second stationary grinding block being engaged and connected.

[0010] Preferably, a motor is installed at the lower end of the interior of the grinding box, and a rotating rod is movably installed between the second grinding groove and the inclined groove. The lower end of the rotating rod is connected to the output end of the motor, and the upper end of the rotating rod is connected to the first moving grinding block.

[0011] Preferably, a first rotating shaft is installed at the upper end of the first moving grinding block, and a second rotating shaft is installed at the lower end of the second moving grinding block. A connecting cylinder is sleeved on the outer side of the first and second rotating shafts. Limiting grooves are provided at the upper and lower ends of the first and second rotating shafts, and the upper and lower ends of the connecting cylinder are engaged and installed inside the limiting grooves.

[0012] Preferably, a first helical gear is installed at one end of the first rotating shaft and the second rotating shaft inside the connecting cylinder, and a second fixing rod is installed through one end of the connecting cylinder. A second helical gear is movably installed at one end of the second fixing rod inside the connecting cylinder, and the second helical gear is meshed with the first helical gear. The end of the second fixing rod away from the connecting cylinder is installed inside the first grinding groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) In this utility model, after the user pours the raw material into the No. 1 grinding tank through the feed port, it can be initially sealed by the sealing cover. Then, the grinding liquid is injected between the raw material and the No. 2 moving grinding block through the liquid injection pipe and the liquid outlet hole. This can not only assist the raw material in grinding, but also avoid the situation of dust overflow, and better protect the outside world. Then, through the cooperation between the No. 2 moving grinding block and the No. 1 moving grinding block, multi-stage grinding of the raw material can be achieved, further improving the grinding effect of the raw material.

[0015] (2) In this utility model, the cooperation between the first helical gear and the second helical gear makes the rotation direction between the first moving grinding block and the second moving grinding block opposite. Thus, strong shearing force and friction force can be generated through the opposite rotation, so as to more effectively crush and refine the raw material particles. Attached Figure Description

Several liquid outlet holes 9 are provided through the annular groove 8 and the first grinding groove 101. A liquid injection pipe 10 is installed through the upper part of one side of the grinding box 1. The liquid injection pipe 10 is connected to the annular groove 8.

[0025] like Figures 4 to 6As shown, in another embodiment of this utility model, fixing plates 6 are respectively installed at the front and rear ends of the feed inlet 3 near the injection pipe 10. A fixing rod 5 is fixedly installed between the fixing plates 6. The lower end of the sealing cover 4 is movably installed between the fixing plates 6, and the rod body of the fixing rod 5 is movably installed through the inside of the sealing cover 4. A torsion spring is installed between the sealing cover 4 and the fixing rod 5. The grinding mechanism 7 includes a first moving grinding block 703 and a second moving grinding block 705. The first moving grinding block 703 is movably installed in the second grinding tank 103. Inside the upper part of the first grinding tank 101, a stationary grinding block 704 is fixedly installed. A movable grinding block 703 is engaged with the stationary grinding block 704. A movable grinding block 705 is movably installed inside the upper part of the first grinding tank 101. A stationary grinding block 706 is fixedly installed inside the upper part of the first grinding tank 101. A movable grinding block 705 is engaged with the stationary grinding block 706. A motor 701 is installed inside the lower part of the grinding box 1. The second grinding tank 103 and the inclined groove 104 are connected... A rotating rod 702 is installed throughout the movement. The lower end of the rotating rod 702 is connected to the output end of the motor 701, and the upper end of the rotating rod 702 is connected to the first moving grinding block 703. A first rotating shaft 707 is installed on the upper end of the first moving grinding block 703, and a second rotating shaft 708 is installed on the lower end of the second moving grinding block 705. A connecting sleeve 710 is sleeved on the outer side of the first rotating shaft 707 and the second rotating shaft 708. Limiting grooves 709 are respectively provided at the upper and lower ends of the first rotating shaft 707 and the second rotating shaft 708. The upper and lower ends of the connecting sleeve 710 are respectively provided with limiting grooves 709. The locking mechanism is installed inside the limiting groove 709. One helical gear 711 is installed at one end of the first rotating shaft 707 and the second rotating shaft 708 inside the connecting cylinder 710. A second fixing rod 712 is installed through one end of the connecting cylinder 710. A second helical gear 713 is movably installed at one end of the second fixing rod 712 inside the connecting cylinder 710, and the second helical gear 713 is meshed with the first helical gear 711. The end of the second fixing rod 712 away from the connecting cylinder 710 is installed inside the first grinding groove 101.

[0026] When grinding the raw materials is required, the user starts the motor 701. The motor 701 then drives the rotating rod 702 and the first moving grinding block 703 to rotate. The first moving grinding block 703 then drives the first rotating shaft 707 and its corresponding first helical gear 711 to rotate. The first helical gear 711 then drives the second helical gear 713 to rotate. The second helical gear 713 then drives the upper first helical gear 711 to rotate. The upper first helical gear 711 then drives the second rotating shaft 708 and the second moving grinding block 705 to rotate, thus making the rotation angles of the first moving grinding block 703 and the second moving grinding block 705 opposite. The user can then open the sealing cover 4 through the first fixing rod 5 to add the raw materials. After the raw materials are added, the process is complete. Then, the torsion spring can push the sealing cover 4 to perform the sealing work. At the same time, the second moving grinding block 705 throws the raw material outward by the centrifugal force when rotating, allowing the raw material to enter the grinding gap between the second moving grinding block 705 and the second stationary grinding block 706 for sealing. Then, the grinding liquid enters the interior of the annular groove 8 through the injection pipe 10. The grinding liquid inside the annular groove 8 then flows towards the gap through the liquid outlet 9 to assist in the grinding of the raw material. After the initial grinding, the raw material and grinding liquid can fall along the first grinding groove 101 and the connecting pipe 102 into the space between the first moving grinding block 703 and the first stationary grinding block 704 for secondary grinding. Finally, the ground raw material can fall along the inclined groove 104 and the discharge port 105 into the interior of the storage box 2 for recycling.

[0027] The gaps between the first moving grinding block 703 and the first stationary grinding block 704, and between the second moving grinding block 705 and the second stationary grinding block 706, are all set to narrow from top to bottom, thereby improving the overall grinding efficiency and grinding effect.

[0028] The inside of each liquid outlet hole 9 is equipped with a filter screen to prevent splashing of raw materials during the initial grinding process from entering the liquid outlet hole 9 and causing blockage. This allows the grinding liquid to flow more stably along the liquid outlet hole 9.

[0029] The working principle of a grinding device for lithium phosphate processing:

[0030] In use, when grinding the raw materials is required, the user starts the motor 701. The motor 701 then drives the rotating rod 702 and the first moving grinding block 703 to rotate. The first moving grinding block 703 then drives the first rotating shaft 707 and its corresponding first helical gear 711 to rotate. The first helical gear 711 then drives the second helical gear 713 to rotate. The second helical gear 713 then drives the upper first helical gear 711 to rotate. The upper first helical gear 711 then drives the second rotating shaft 708 and the second moving grinding block 705 to rotate, thus making the rotation angles of the first moving grinding block 703 and the second moving grinding block 705 opposite. The user can then open the sealing cover 4 through the first fixing rod 5 to add the raw materials. After the grinding is completed, the torsion spring can push the sealing cover 4 to perform the sealing work. At the same time, the second moving grinding block 705 uses the centrifugal force during rotation to throw the raw material outward, allowing the raw material to enter the grinding gap between the second moving grinding block 705 and the second stationary grinding block 706 for sealing. Then, the grinding liquid enters the interior of the annular groove 8 through the injection pipe 10. The grinding liquid inside the annular groove 8 then flows towards the gap through the liquid outlet 9 to assist in the grinding of the raw material. After the initial grinding, the raw material and grinding liquid can fall along the first grinding groove 101 and the connecting pipe 102 into the space between the first moving grinding block 703 and the first stationary grinding block 704 for secondary grinding. Finally, the ground raw material can fall along the inclined groove 104 and the discharge port 105 into the interior of the storage box 2 for recycling.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
