Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to an anti-clogging waste battery crusher. Background Art

[0002] The recycling of used batteries generally requires processes such as crushing, magnetic separation, air separation, gravity separation, and screening. In the crushing process, in order to completely crush the used batteries, the batteries need to be roughly shredded and sheared first, and then sent to the crusher for fine crushing into granular materials. Both the rough shredding and fine crushing processes need to be carried out in an inert gas protection environment. In order to save the space occupied by the machine and reduce the transportation path and the complexity of transportation, the crusher in the prior art often adopts a shredding and crushing integrated mechanism. The shredded materials pass through a connecting channel and directly enter the crushing module for further crushing. Due to the small diameter of the connecting channel, during the operation of the machine, the residue after crushing may adhere to the channel wall and continue to accumulate in the channel, reducing the flow cross-sectional area. Over time, the channel will be blocked, thereby affecting the stable flow and transportation of the material and affecting the normal operation of the crusher. Therefore, it is necessary to manually dredge the channel regularly, and the manual dredging method will not only affect or destroy the inert gas protection environment in the shredding module and the crushing module, but also increase the work intensity of the workers. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides an anti-clogging waste battery crusher, which solves the problem that the connection channel of the shredding and crushing integrated mechanism in the prior art is easily blocked.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] Provided is a blockage-resistant waste battery crusher, which comprises a shredding module for coarse crushing, a connecting channel for conveying, and a pulverizing module for fine crushing, which are sequentially connected from top to bottom;

[0006] A high-pressure blowing device is arranged inside the connecting channel; the high-pressure blowing device comprises a blowing pipe, and a plurality of nozzles are connected to the blowing pipe; one end of the blowing pipe extends out of the connecting channel and is connected to an external high-pressure nitrogen source, and the blowing pipe wall is sealed and connected to the connecting channel wall; an electromagnetic valve electrically connected to the controller is installed on the blowing pipe located outside the connecting channel.

[0007] The beneficial effects of the utility model are as follows: the material roughly crushed by the shredding module can automatically fall to the connecting channel and then to the crushing module under the drive of gravity, which is simple to transport and has a short path. A high-pressure blowing device is arranged inside the connecting channel. By controlling the opening and closing of the solenoid valve by the controller, high-pressure nitrogen can be regularly blown into the connecting channel as an auxiliary driving force, forming an airflow shovel on the wall of the connecting channel to remove the attached residues, avoid continuous accumulation of residues, ensure continuous and stable material transportation, and effectively avoid residues blocking the connecting channel.

[0008] Furthermore, a section of the connecting channel close to the crushing module is a buffer zone, which is a bent structure; the blowing pipe is fixed to the starting end of the buffer zone. The buffer zone is set so that the shredding module and the crushing module are staggered and not on the same vertical line, which reduces the occurrence of the material in the crushing module bouncing to the shredding module above, and weakens the mutual influence of the two working modules.

[0009] Furthermore, the nozzles include long-nozzle nozzles and short-nozzle nozzles; a long-nozzle nozzle and a short-nozzle nozzle constitute a group of nozzles, and multiple groups of nozzles are evenly spaced and fixedly connected to the blowing pipe; the short-nozzle nozzle extends into the front section of the buffer zone, and the long-nozzle nozzle extends into the middle section of the buffer zone. The front section and the end of the bend of the buffer zone are both locations where blockage is prone to occur. At the same time, both long and short nozzles are set, and the blowing airflow is evenly distributed, evenly flushing the connecting channel to avoid the occurrence of blowing dead corners.

[0010] Furthermore, the blowing pipe located inside the connecting channel is at an acute angle to the horizontal line. The blowing pipe is placed obliquely so that the material falling on the blowing pipe continues to slide down, thereby preventing the material from being retained on the blowing pipe.

[0011] Furthermore, the shredding module includes at least two shredding shafts, and a plurality of blades are fixedly connected along the axial direction of the shredding shafts; the shredding shafts are connected to a motor, and the motor is electrically connected to a controller; the rotation directions of two adjacent shredding shafts are opposite, and the blades thereon are staggered.

[0012] Furthermore, a feed port is provided above the shredding shaft, and a feed valve for controlling the opening and closing of the feed port is provided on the feed port, and the feed valve is electrically connected to the controller; an oxygen detection sensor for monitoring oxygen concentration is provided inside the shredding module and the crushing module, and an air intake assembly for introducing inert gas is connected. When the oxygen detection sensor detects that the oxygen concentration is higher than the set value, the controller can control the feed valve and the motor to close, stop feeding, and stop the machine operation, so as to ensure that the oxygen concentration is always lower than the set value during operation to ensure safety.

[0013] Furthermore, a feed plate tilted downward is fixedly connected to the feed inlet, and the feed plate can change the material movement path and guide the battery to enter the middle of the two shredding shafts.

[0014] Furthermore, the crushing module includes a hammer assembly and multiple impact blocks, the hammer assembly is connected to the motor, and the motor is electrically connected to the controller; an arc screen is arranged below the hammer assembly; the multiple impact blocks are distributed in an arc shape and fixed to the side wall of the shell of the crushing module.

DETAILED DESCRIPTION

[0018] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0019] like Figure 1 As shown, the anti-clogging waste battery crusher of this solution includes a shredding module 10 for coarse crushing, a connecting channel 30 for conveying, and a crushing module 20 for fine crushing, which are sequentially connected from top to bottom. The material coarsely crushed by the shredding module 10 can automatically fall to the connecting channel 30 and then to the crushing module 20 under the drive of gravity, which is simple to convey and has a short path. This solution also includes a support frame 40 for supporting the shredding module 10, the connecting channel 30 and the crushing module 20.

[0020] A high-pressure blowing device 60 is arranged inside the connecting channel 30; the high-pressure blowing device 60 includes a blowing pipe 64, and a plurality of nozzles 63 are connected to the blowing pipe 64; one end of the blowing pipe 64 extends out of the connecting channel 30 and is connected to an external high-pressure nitrogen source 61, and the wall of the blowing pipe 64 is sealed and connected to the wall of the connecting channel 30; a solenoid valve 62 electrically connected to the controller is installed on the blowing pipe 64 located outside the connecting channel 30. The controller can be an industrial controller with a PLC element. By controlling the opening and closing of the solenoid valve 62 by the controller, high-pressure nitrogen can be sprayed into the connecting channel 30 at a fixed time as a boosting force, forming an air flow shovel on the wall of the connecting channel 30 to remove the attached residue, avoid continuous accumulation of residue, ensure continuous and stable material transportation, and effectively avoid residue blocking the connecting channel 30. Automatic control can avoid affecting the nitrogen protection environment during manual dredging, reduce the labor intensity of manual work, and the sprayed nitrogen can be left in the shredding module 10 and the crushing module 20 as a protective gas to assist in reducing the oxygen content inside the machine.

[0021] As an embodiment of the utility model, a section of the connecting channel 30 close to the crushing module 20 is a buffer zone 31, and the buffer zone 31 is a bent structure; the blowing pipe 64 is fixed to the starting end of the buffer zone 31. The buffer zone 31 is set so that the shredding module 10 and the crushing module 20 are staggered and not on the same vertical line, which reduces the occurrence of the material in the crushing module 20 bouncing toward the shredding module 10 above, and weakens the mutual influence of the two working modules. It also has a certain deceleration effect on the material, which can prevent the material from directly performing free fall motion, resulting in excessive final velocity and excessive impact.

[0022] like Figure 2 As shown, when the utility model is implemented, the nozzle 63 preferably includes a long nozzle 631 and a short nozzle 632. A long nozzle 631 and a short nozzle 632 constitute a group of nozzles 63, and multiple groups of nozzles 63 are evenly spaced and fixedly connected to the blowing pipe 64; the short nozzle 632 extends into the front section of the buffer zone 31, and the long nozzle 631 extends into the middle section of the buffer zone 31. The nozzle shape of the nozzle 63 is preferably matched with the curved shape of the bend of the buffer zone 31 to avoid direct contact with the bend wall. The front section and the end of the bend of the buffer zone 31 are both locations where blockage is prone to occur. At the same time, two types of long and short nozzles 63 are set, and the high-pressure airflow can reach all positions from the front section to the end of the bend of the buffer zone 31, and the evenly distributed nozzles 63 make the blowing airflow evenly distributed, evenly flush the connecting channel 30, and avoid the occurrence of blowing dead corners.

[0023] Preferably, the blowing pipe 64 located inside the connecting channel 30 is at an acute angle to the horizontal line. The blowing pipe 64 is placed at an angle so that the material falling on the blowing pipe 64 continues to slide down, avoiding the material from being retained on the blowing pipe 64.

[0024] In one embodiment of the utility model, the shredding module 10 includes at least two shredding shafts 11, and a plurality of blades are fixedly connected along the axial direction of the shredding shafts 11; the shredding shafts 11 are connected to a motor, and the motor is electrically connected to a controller; the rotation directions of two adjacent shredding shafts 11 are opposite, and the blades thereon are staggered. The motor drives the shredding shafts 11 to rotate, and when the two adjacent shredding shafts 11 move toward each other, the staggered blades thereon can shred the entire battery, and the motor can be automatically turned on or off by the controller. The shredding shafts 11 can be two or four, two in a group, and the shredding shafts 11 in the same group rotate toward each other.

[0025] A feed port is provided above the shredding shaft 11, and a feed valve 12 for controlling the opening and closing of the feed port is provided on the feed port, and the feed valve 12 is electrically connected to the controller; the shredding module 10 and the crushing module 20 are both provided with an oxygen detection sensor for monitoring the oxygen concentration, and are connected with an air intake assembly 50 for introducing an inert gas. When the oxygen detection sensor detects that the oxygen concentration is higher than the set value, the controller can control the feed valve 12 and the motor to close, stop feeding, and stop the machine operation to ensure that the oxygen concentration is always lower than the set value during operation to ensure safety. The battery can be transported from a low place to the feed port by a conveyor crawler. The oxygen detection sensor can be a zirconium oxide detector probe. A feed plate 13 tilted downward is fixedly connected to the feed port. The feed plate 13 can change the material movement path and guide the battery into the middle of the two shredding shafts 11.

[0026] The crushing module 20 includes a hammer assembly 21 and a plurality of impact blocks 22. The hammer assembly 21 is connected to a motor, and the motor is electrically connected to a controller. An arc screen 23 is arranged below the hammer assembly 21. The plurality of impact blocks 22 are distributed in an arc shape and fixed to the side wall of the shell of the crushing module 20. The motor can drive the hammer assembly 21 to rotate at a high speed. The material is impacted by the hammer assembly 21 rotating at a high speed and is crushed. The material obtains kinetic energy from the hammer assembly 21 and rushes toward the impact block 22 and the screen 23 at a high speed. The materials collide with each other and are crushed multiple times. When the particle size is smaller than the gap of the screen 23, the material is squeezed out of the gap, thereby obtaining a finished material of the required particle size. A discharge port is arranged at the bottom of the shell of the crushing module 20. The discharge port can also be provided with a valve for controlling the opening and closing. After the finished material falls to the bottom of the shell, a conveyor belt can be used to output the finished material.

[0027] In summary, this solution can automatically and regularly spray high-pressure nitrogen into the connecting channel through the control of the controller to avoid continuous accumulation of residues, ensure continuous and stable material transportation, and effectively prevent residues from blocking the connecting channel.
