Description

Technical Field

[0001] The 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 group of fixed jaw plates and a group of moving jaw plates to form a V-shaped structure to crush objects. During the moving jaw plate's moving crushing process, the material that has been crushed to a suitable size automatically falls through the V-shaped opening, and the material is automatically driven down by gravity. Although the material can be sorted and discharged 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 in a short period of time will generate a lot of heat. On the one hand, it is easy to cause the lithium battery to spontaneously combust during crushing.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 plate frame 20 is arranged, and the jaw plate frame 20 rotates around the connection between the frame 10 and the frame 10 to form an angle adjustment structure, a fixed jaw plate 21 is arranged on the jaw plate frame 20, and a movable jaw plate 22 forming a V-shaped crushing chamber therewith is arranged on one side of the fixed jaw plate 21, and the movable jaw plate 22 reciprocates around the connection between the jaw plate frame 20 and the jaw plate frame 20, and the jaw plate frame 20 rotates around the connection between the frame 10 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, and 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 is movably abutted 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-closed V-shaped crushing chamber is conducive to creating a low-temperature crushing environment, and tries to avoid 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, and the lithium battery slides into the V-shaped crushing chamber by gravity, and 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 a 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, the V-shaped crushing chamber is driven 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 full 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 flexibly 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 beneficial to synchronous rotation through a single drive, which is beneficial to reducing the setting of the drive device and is beneficial 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 penetrated 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 meshed 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, and the movable jaw plate 22 and the feed plate 30 are driven to rotate synchronously in both directions while the shaft 34 rotates;

[0051] The shaft 34 directly drives the movable jaw plate 22 to rotate, and at the same time, the driving gear 332 and the movable jaw plate 22 rotate in the same direction, the driving gear 332 meshes with the connecting gear 333 to rotate in the same direction, and the connecting gear 333 externally meshes with the driven gear 334, so that the driven gear 334 rotates in the opposite direction, and further drives the feed plate 30 to rotate in the opposite direction, thereby achieving the purpose of two-way rotation. During the crushing process, the inclination of the V-shaped crushing chamber can be slowed down, and the feed plate 30 can be driven to suspend feeding, thereby achieving the purpose of interval feeding and crushing.

[0052] like Figure 2 , Figure 3 and Figure 5 As shown, the movable jaw plate 22 is rotatably connected to the jaw plate frame 20 through a main bearing 221, a flywheel 222 is disposed at one end of the main bearing 221, and a fixing ring 11 movably connected to the flywheel 222 is disposed on the frame 10;

[0053] A buffer pad is fixedly disposed on the outer wall of the main bearing 221 , and the main bearing 221 rotates around the shaft 34 and movably abuts against the feed plate 30 to form a semi-closed structure.

[0054] The flywheel 222 and the main bearing 221 are driven externally to drive the movable jaw plate 22 to move, so that the movable jaw plate 22 continuously squeezes the lithium battery in the V-shaped crushing chamber 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 together. When the movable jaw plate 22 rotates to a suitable position, the main bearing 221 abuts against the feed plate 30 through the buffer pad to form a semi-closed structure, thereby stopping the feeding into the V-shaped crushing chamber, which is conducive to separating the materials for crushing.

[0056] like Figure 2 , Figure 4 and Figure 6 As shown, a blanking plate 25 is provided on the extension line of the fixed end of the fixed jaw plate 21, and a drainage groove 26 is provided on the blanking plate 25. The blanking plate 25 includes a fixed plate 251 and a partition plate 252. The partition plate 252 is a concave structure, and a fracture is provided at the connection between the fixed plate 251 and the partition plate 252;

[0057] The drainage groove 26 is in a funnel-shaped structure, and the length direction of the drainage groove 26 runs through the length direction of the fixing plate 251 , and the drainage groove 26 is connected to the fracture.

[0058] The unloading plate 25 is used to extend one end of the fixed jaw plate 21 to guide the unloading. At the same time, the drainage groove 26 on the unloading plate 25 is conducive to guiding the flow of waste liquid, facilitating the collection of waste liquid to achieve the purpose of solid-liquid separation, and further helps to reduce the possibility of reaction between electrolyte and broken lithium batteries, thereby reducing the 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, and 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 cooler.

[0060] By embedding the cold air channel 24 in 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 dispersion of cold air entering the V-shaped crushing chamber through the cold air channel 24 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 reduce 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 below the fracture of the blanking plate 25, and 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 liquid such as electrolyte during crushing, thereby reducing the possibility of explosion caused by the reaction between the electrolyte and the crushed lithium battery during the crushing process, and at the same time, it is beneficial to discharge the solid and liquid separately;

[0063] The waste liquid in the V-shaped crushing chamber enters the collecting pipe 28 through the liquid inlet 211 and the discharge pipe 27. When discharging, the waste liquid flowing to the unloading plate 25 enters the collecting pipe 28 through the fracture and is discharged together, thereby reducing the waste liquid 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, and 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 alternately, 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 rise and explosion when the lithium battery in the V-shaped crushing chamber is crushed, thereby further achieving the purpose of explosion prevention.

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

[0068] A fixed tooth plate 212 is provided on the fixed jaw plate 21 along the length direction, and a movable tooth plate 223 is provided on the movable jaw plate 22 along the length direction. The fixed tooth plate 212 and the movable tooth plate 223 are meshed with each other, and the liquid inlet 211 passes through the upper surface of the fixed tooth plate 212 .

[0069] The side guard plates 29 are used to surround and seal both sides of the movable jaw plate 22 and the fixed jaw plate 21, thereby facilitating the formation of a low-temperature crushing chamber;

[0070] During crushing, the movable jaw plate 22 reciprocates toward the fixed jaw plate 21, continuously squeezing and crushing the lithium batteries in the V-shaped crushing chamber, and rubbing the lithium batteries in the V-shaped crushing chamber through the fixed tooth plate 212 and the movable tooth plate 223, which helps to enhance the crushing effect.

The protection scope of the present application is defined by the claims.
