Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery crushing, and in particular to an explosion-proof jaw crusher for crushing lithium batteries. Background Art

[0002] Traditional jaw crushers usually use a set of fixed jaw plates and a set of moving jaw plates to form a V-shaped structure to crush objects. During the moving jaw plate's moving crushing process, the material crushed to a suitable size automatically falls through the V-shaped opening, and gravity drives the material to automatically descend. Although it can sort and discharge the material to a certain extent, in the crushing of waste lithium batteries, due to the presence of electrolyte, the crushed materials will stick together and are not easy to separate, affecting the separation and recovery of the various components of the lithium battery.

[0003] In addition, the conventional vertical V-shaped opening causes the material to be concentrated to the V-shaped opening due to gravity during crushing. When the material is concentrated at the lower end for crushing, a large amount of crushing will generate a lot of heat in a short period of time. On the one hand, it is easy to cause the lithium battery to spontaneously combust during crushing. On the other hand, the accumulated material will also increase the crushing pressure in the same area of ​​the jaw plate, affecting the crushing effect. Summary of the Invention

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figure 1 As shown, the present invention provides an explosion-proof jaw crusher for crushing lithium batteries, including a frame 10, on which a jaw frame 20 is provided. The jaw frame 20 rotates around the connection between it and the frame 10 to form an angle adjustment structure, a fixed jaw 21 is provided on the jaw frame 20, and a movable jaw 22 is provided on one side of the fixed jaw 21 to form a V-shaped crushing chamber therewith. The movable jaw 22 reciprocates around the connection between it and the jaw frame 20, the jaw frame 20 rotates around the connection between it and the frame 10 to form an angle adjustment, and the V-shaped crushing chamber rotates synchronously to form a material discharge buffer structure.

[0040] A feed plate 30 is provided at the feed end of the fixed jaw plate 21. The feed plate 30 rotates in the opposite direction to the V-shaped crushing chamber around the connection between the feed plate 30 and the fixed jaw plate 21, and the feed plate 30 movably abuts against one end of the movable jaw plate 22 to form a spaced feeding structure.

[0041] A water cooling pipe 23 is provided on the fixed jaw plate 21, and a cold air channel 24 is provided at the fixed end of the movable jaw plate 22. The cold air guided out from the cold air channel 24 enters the V-shaped crushing chamber and forms a low-temperature circulating gas atmosphere with the cooperation of the water cooling pipe 23.

[0042] The present invention adopts a rotating form to form a jaw crushing mechanism with an interval feeding structure. During crushing, the V-shaped crushing chamber is rotated to slow down the crushing process, expand the contact between the low-temperature jaw plate and the material, and reduce the heat generated during crushing. At the same time, the semi-enclosed V-shaped crushing chamber is conducive to creating a low-temperature crushing environment, and minimizes the thermal runaway and explosion in the V-shaped crushing chamber, thereby achieving the purpose of explosion-proof crushing.

[0043] By rotating the jaw plate frame 20, closed feeding is achieved, and the purpose of interval feeding is realized, which is beneficial to reducing the possibility of combustion and explosion. At the same time, the V-shaped crushing chamber is slowed down, which is beneficial to expanding the contact between the lithium battery and the inner wall of the V-shaped crushing chamber, and the lithium battery shell is cooled as much as possible, thereby reducing the heat generated in the crushing process, and further achieving the purpose of avoiding combustion and explosion as much as possible.

[0044] like Figure 1 and Figure 2As shown, the feed plate 30 is coaxially arranged on the extension line of the fixed jaw plate 21. The lithium battery slides into the V-shaped crushing chamber by gravity. The fixed jaw plate 21 rotates around the axis to tilt the V-shaped crushing chamber to form a material discharge buffer structure, and the feed plate 30 is coaxially reversed to form a closed structure.

[0045] A feed hopper 31 located on a feed plate 30 is provided on the frame 10 , and a baffle 32 is provided on one side of the feed plate 30 . The baffle 32 movably abuts against the discharge end of the feed hopper 31 to form a sealing structure.

[0046] The lithium battery slides into the V-shaped crushing chamber through the feed plate 20. During crushing, the rotating fixed jaw plate 21 drives the baffle 32 to close the discharge port of the feed hopper 31, thereby achieving the purpose of interval feeding. At the same time, it drives the V-shaped crushing chamber to tilt, which is conducive to slowing down the V-shaped crushing chamber, reducing the pressure at the discharge port of the V-shaped crushing chamber, and expanding the contact surface of the lithium battery in the V-shaped crushing chamber to achieve the purpose of sufficient crushing.

[0047] During feeding, the lithium batteries first enter the feed hopper 31 and slide along the feed plate 30 into the V-shaped crushing chamber. When there are enough lithium batteries in the V-shaped crushing chamber, the fixed jaw plate 21 is rotated to drive the baffle 32 to movably abut against the bottom of the feed hopper 31 to form a partition, thereby suspending the feeding and achieving the purpose of interval feeding. The baffle 32 is rotated by the fixed jaw plate 21, which is conducive to synchronous rotation through a single drive, which is conducive to reducing the setting of the drive device and is also conducive to synchronous control.

[0048] like Figure 3 and Figure 5 As shown, a swing assembly 33 is provided on the frame 10, and the swing assembly 33 is connected to the movable jaw plate 22 through a shaft 34, and the shaft 34 is passed through the movable jaw plate 22 and the feed plate 30 to form a coaxial bidirectional rotation structure;

[0049] Among them, the swing assembly 33 includes a driving motor 331, a driving gear 332, a connecting gear 333 and a driven gear 334. The output shaft of the driving motor 331 is fixedly connected to the shaft 34 through a coupling, and the outer wall of the shaft 34 is fixedly penetrated into the driving gear 332. The driven gear 334 is sleeved on the outer wall of the shaft 34 and fixedly connected to the feed plate 30. The two ends of the connecting gear 333 are respectively engaged with the inner wall of the driving gear 332 and the outer wall of the driven gear 334.

[0050] The shaft 34 is controlled to rotate by the driving motor 331, driving the jaw plate frame 20 to rotate as a whole. When the shaft 34 rotates, the movable jaw plate 22 and the feed plate 30 are driven to rotate synchronously in both directions.

[0051] The shaft rod 34 directly drives the movable jaw plate 22 to rotate, and the driving gear 332 rotates with the movable jaw plate 22. The driving gear 332 is connected with the connecting gear 333 to rotate in the same direction, and the connecting gear 333 is connected with the driven gear 334 to rotate in the opposite direction, thereby driving the feeding plate 30 to rotate in the opposite direction, so as to achieve the purpose of bidirectional rotation. During the crushing process, the V-shaped crushing cavity is inclined and slowed down, and the feeding plate 30 is temporarily stopped to discharge, so as to achieve the purpose of interval discharging and crushing.

[0052] As shown in Figure 2 , Figure 3 and Figure 5 , the movable jaw plate 22 is rotatably connected with the jaw plate frame 20 through the main bearing 221, one end of the main bearing 221 is provided with a flywheel 222, and the fixed ring 11 is movably connected with the flywheel 222 on the frame 10.

[0053] The outer wall of the main bearing 221 is fixedly provided with a buffer pad, and the main bearing 221 rotates around the shaft rod 34 and is movably abutted with the feeding plate 30 to form a semi-closed structure.

[0054] The flywheel 222 and the main bearing 221 are driven by external driving to drive the movable jaw plate 22 to move, so that the movable jaw plate 22 continuously extrudes the lithium battery in the V-shaped crushing cavity and cooperates with the fixed jaw plate 21 to achieve the purpose of crushing.

[0055] During the rotation of the fixed jaw plate 21, the movable jaw plate 22 is driven to rotate, and when the movable jaw plate 22 rotates to the appropriate position, the main bearing 221 is abutted with the feeding plate 30 through the buffer pad to form a semi-closed structure, so as to stop the continuous feeding in the V-shaped crushing cavity, which is beneficial to the interval discharging and crushing.

[0056] As shown in Figure 2 , Figure 4 and Figure 6 , the fixed jaw plate 21 is provided with a discharging plate 25 on the extension line of the fixed end, and the discharging plate 25 is provided with a flow guide groove 26. The discharging plate 25 includes a fixed plate 251 and a partition plate 252. The partition plate 252 is in a concave structure, and the fixed plate 251 is provided with a fracture at the connection with the partition plate 252.

[0057] The flow guide groove 26 is in a funnel structure, and the length direction of the flow guide groove 26 penetrates the length direction of the fixed plate 251. The flow guide groove 26 is connected with the fracture.

[0058] The discharging plate 25 extends one end of the fixed jaw plate 21 to guide the discharging. The flow guide groove 26 on the discharging plate 25 is beneficial to guiding the flow direction of the waste liquid, facilitating the collection of the waste liquid, achieving the purpose of solid-liquid separation, and further reducing the possibility of reaction between the electrolyte and the crushed lithium battery, thereby reducing the risk of explosion.

[0059] like Figure 2 As shown, an air inlet matching the cold air channel 24 is opened on the movable jaw plate 22. One end of the cold air channel 24 is connected to the V-shaped crushing chamber to form a low-temperature crushing chamber. The other end of the cold air channel 24 passes through the outer wall of the movable jaw plate 22 and is connected to the air conditioner.

[0060] By building the cold air channel 24 into the feed end of the movable jaw plate 22, it is beneficial to keep the air inlet always located at the opening of the V-shaped crushing chamber. When the opening of the V-shaped crushing chamber is closed, the escape of cold air from the cold air channel 24 into the V-shaped crushing chamber can be reduced. The cold air is guided into the V-shaped crushing chamber through the air inlet, thereby creating a low-temperature crushing environment, which is beneficial to reducing the situation where a large amount of heat is generated during crushing and causes combustion and explosion, thereby achieving the purpose of explosion prevention.

[0061] like Figure 4 As shown, a drain pipe 27 is provided in the fixed jaw plate 21, and a liquid inlet 211 is opened on the upper surface of the fixed jaw plate 21. One end of the drain pipe 27 is connected to the liquid inlet 211, and the other end of the drain pipe 27 has a liquid collecting pipe 28 extending to the bottom of the blanking plate 25. The liquid is discharged through the liquid collecting pipe 28.

[0062] By setting multiple groups of liquid inlets 211 at equal intervals on the surface of the fixed jaw plate 21, it is beneficial to guide the discharge of waste liquids such as electrolyte during crushing, thereby reducing the possibility of explosion caused by the reaction between electrolyte and crushed lithium batteries during the crushing process, and at the same time facilitating the separate discharge of solid and liquid;

[0063] The waste liquid in the V-shaped crushing chamber enters the collecting pipe 28 through the liquid inlet 211 and the drain pipe 27. When discharging, the waste liquid flowing to the discharge plate 25 enters the collecting pipe 28 through the fracture and is discharged together, thereby reducing the waste liquid from being discharged along with the crushed lithium batteries.

[0064] like Figure 2 and Figure 4 As shown, the length direction of the water cooling pipe 23 is parallel to the length direction of the fixed jaw plate 21 to form a low-temperature fixed jaw plate 21. The material slides onto the fixed jaw plate 21 and enters the low-temperature crushing chamber for double cooling treatment.

[0065] The water cooling pipe 23 and the drain pipe 27 are arranged in an interlaced manner, and the water cooling pipe 23 is located above the drain pipe 27 in the fixed jaw plate 21 .

[0066] The material on the fixed jaw plate 21 is cooled by the water cooling pipe 23, and at the same time, cold air enters the V-shaped crushing chamber to cool the V-shaped crushing chamber. The double cooling method controls the temperature increase and explosion when the lithium battery in the V-shaped crushing chamber is crushed, thereby further achieving the purpose of explosion prevention.

[0067] As shown in Figure 2 , Figure 4 and Figure 5 , the side guard 29 is fixed on the jaw frame 20, and the side guard 29 connects the movable jaw 22 and the fixed jaw 21 to form a semi-enclosed structure.

[0068] Wherein, the fixed jaw 21 is provided with a fixed tooth plate 212 along the length direction, and the movable jaw 22 is provided with a movable tooth plate 223 along the length direction, the fixed tooth plate 212 and the movable tooth plate 223 are engaged, and the liquid inlet 211 penetrates the upper surface of the fixed tooth plate 212.

[0069] The two sides of the movable jaw 22 and the fixed jaw 21 are enclosed by the side guard 29, so as to facilitate the formation of a low-temperature crushing cavity.

[0070] During crushing, the movable jaw 22 reciprocates towards the fixed jaw 21 to continuously crush the lithium battery in the V-shaped crushing cavity, and the lithium battery in the V-shaped crushing cavity is rubbed by the fixed tooth plate 212 and the movable tooth plate 223, so as to enhance the crushing effect.
