Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crusher, in particular to a special crusher for power lead-acid battery. BACKGROUND

[0002] Lead-acid battery is the largest production and the most widely used battery in the world. However, with the increasing use of batteries, a large number of waste batteries are generated, which contain a large amount of lead metal and electrolyte solution such as waste acid and waste alkali. Recycling and reusing the used lead-acid battery not only prevents environmental pollution, but also reuses the recyclable part and saves resources.

[0003] In the recycling process of lead-acid battery, the crushing process is a very important link, and the main equipment is a crusher. The crushing effect of the crusher often determines the recovery rate of the whole process.

[0004] At present, in the lead-acid battery recycling industry, the battery types are mainly divided into dry battery car batteries and automobile starting type batteries. Since the dry battery car battery is small in size and easy to crush, the automobile starting type battery is often large in size due to use requirements. The existing crusher often has low crushing efficiency and is jammed due to the large size. In order to achieve the effect, two crushing or pre-cutting of the battery before crushing is often used. Although the crushing process is mature, two crushing is required, the supporting equipment is more, the process and control of the crushing process are complex, the space required for equipment installation is large, and due to the large power of a single crusher, the energy consumption is large, the enterprise equipment investment and operation cost are high. SUMMARY

[0005] The purpose of the present application is to provide a special crusher for power lead-acid battery, which can complete twice crushing of the battery by one operation, greatly simplify the process of the crushing process, reduce the supporting equipment, effectively reduce the energy consumption and enterprise equipment investment and operation cost, and has high crushing efficiency, good crushing effect and long service life of the equipment.

[0006] The above technical purpose of the present application is realized by the following technical scheme:

[0007] A special crusher for power lead-acid battery, comprising a base, a barrel is arranged on the base, an upper end of the barrel is provided with an upper cover, the upper cover is provided with a feeding port, a bottom of the barrel is provided with a discharging port, the barrel is a "T" shaped cylindrical structure with a larger diameter at the upper end than at the lower end, a rotary crushing mechanism is arranged in the barrel, and the rotary crushing mechanism is connected with a rotary driving mechanism outside the barrel.

[0008] By adopting the above technical scheme, the barrel with the "T"-shaped cylindrical structure can divide the crushing cavity into two parts with large upper part and small lower part, so that the large power battery entering the crusher from the feeding port is firstly pre-crushed (i.e. pre-cut) in the large space of the upper part, and the smaller material obtained after pre-crushing is further crushed in the small space of the lower part, thus effectively solving the problems of low crushing efficiency or jamming caused by the too large volume of the material, and the twice crushing of the battery can be completed through only one operation, which greatly simplifies the process of the crushing procedure, reduces the supporting equipment, and effectively reduces the energy consumption and enterprise equipment investment and operation cost.

[0009] Further, the rotating crushing mechanism comprises a central shaft rotationally connected with the upper cover and the bottom of the barrel respectively, a plurality of parallel rotor discs are fixed on the central shaft, and a plurality of pendulum mechanisms for crushing the material are circumferentially arranged on the rotor discs.

[0010] By adopting the above technical scheme, the central shaft is driven by the rotating driving mechanism to rotate at high speed, and the rotor discs are synchronously rotated at high speed, the pendulum mechanisms installed on the rotor discs are rotated at high speed, and the material entering the barrel is continuously crushed by the pendulum mechanisms in sequence, so that the crushing effect is achieved.

[0011] Further, the pendulum mechanism comprises a fixed pendulum fixedly connected with the bottom of the rotor disc and a movable pendulum rotationally connected with the top of the rotor disc, the movable pendulum is rotationally connected with the top of the rotor disc through a pin shaft, a torsion spring is sleeved on the pin shaft, one end of the torsion spring is fixedly connected with the movable pendulum, the other end of the torsion spring is fixedly connected with the rotor disc, and the movable pendulum is located directly above the fixed pendulum.

[0012] By adopting the above technical scheme, when the pendulum mechanism rotates at a high speed with the rotor disc, the fixed pendulum and the movable pendulum in the pendulum mechanism continuously collide with the material in the barrel, thereby continuously crushing the material, at the same time, the fixed pendulum fixedly connected with the rotor disc in the pendulum mechanism rotates synchronously with the rotor disc, the movable pendulum rotationally connected with the rotor disc in the pendulum mechanism rotates around the pin shaft relative to the rotor disc and the fixed pendulum to the side opposite to the rotating direction of the rotor disc under the action of inertia, when the movable pendulum rotates, one end of the torsional spring is synchronously rotated, so that the torsional spring continuously accumulates elastic force, until the inertia force and the elastic force are equal, the movable pendulum rotates synchronously with the rotor disc, at this time, the fixed pendulum and the movable pendulum are in a crossing state, the greater the rotating speed of the rotor disc, the greater the inertia force, the greater the rotating angle of the movable pendulum around the pin shaft, the smaller the rotating speed of the rotor disc, the smaller the inertia force, the smaller the rotating angle of the movable pendulum around the pin shaft, therefore, when the rotary driving mechanism controls the rotor disc to rotate in a fast-slow-fast-slow cycle manner at a certain frequency, the movable pendulum reciprocally rotates around the pin shaft relative to the rotor disc under the action of the inertia force and the force of the torsional spring, so that the crossing angle of the fixed pendulum and the movable pendulum is in a cycle rotating state of increasing-decreasing-increasing-decreasing, the crossing angle of the fixed pendulum and the movable pendulum is in a cycle change of increasing-decreasing-increasing-decreasing, in this process, the fixed pendulum and the movable pendulum continuously shear the material entering between the fixed pendulum and the movable pendulum, so that the material is further crushed, and the crushing effect is greatly improved.

[0013] The application further provides that the lower end surface of the movable pendulum extending from the rotor disc is attached to the upper end surface of the fixed pendulum extending from the rotor disc.

[0014] By adopting the above technical scheme, the lower end surface of the movable pendulum extending from the rotor disc is attached to the upper end surface of the fixed pendulum extending from the rotor disc, so that when the fixed pendulum and the movable pendulum shear the material, there is no gap between the lower end surface of the movable pendulum extending from the rotor disc and the upper end surface of the fixed pendulum extending from the rotor disc, thereby ensuring that the material is fully sheared, and the shearing effect is better.

[0015] The application further provides that the inner wall of the barrel is fixedly provided with a plurality of counter-hammers at equal intervals in the circumferential direction, the bottom surface of the counter-hammer is attached to and fixedly connected with the inner wall of the barrel, the two side surfaces of the counter-hammer are symmetrically inclined to form a wedge shape, the end of the movable pendulum away from the rotation center is attached to the inner wall of the barrel, and the circumferential diameter of the end of the fixed pendulum is not more than the circumferential diameter of the wedge-shaped end formed by the two side surfaces of the counter-hammer.

[0016] By adopting the technical scheme, the counter-hammer is arranged to collide with the movable pendulum continuously when the movable pendulum rotates with the rotor disc, on one hand, the vibration generated in the collision is utilized to shake down the material adhered to the inner wall of the barrel or clamped between the adjacent rotor discs, thereby avoiding the problem that the material is clamped between the adjacent two rotor discs and cannot be broken, and ensuring that the movable pendulum always has good shearing effect, on the other hand, when the rotating driving mechanism controls the rotor disc to rotate at a constant speed, the movable pendulum and the fixed pendulum rotate synchronously with the rotor disc, at this time, the movable pendulum rotates reversely relative to the rotor disc and the fixed pendulum under the action of inertial force and is in a crossing state with the fixed pendulum, at this time, the torsional spring accumulates a certain spring force and reaches a balance state with the inertial force borne by the movable pendulum, when one end of the movable pendulum collides with the counter-hammer, under the impact of the collision force, the movable pendulum starts to rotate around the pin shaft in the direction opposite to the direction in which the rotor disc rotates, at this time, the crossing angle between the movable pendulum and the fixed pendulum continues to increase, the torsional spring continues to accumulate the spring force, and after the movable pendulum is separated from the counter-hammer, under the action of the rebound force of the torsional spring, the movable pendulum starts to rotate around the pin shaft relative to the rotor disc and the fixed pendulum in the same direction as the direction in which the rotor disc rotates, at this time, the crossing angle between the movable pendulum and the fixed pendulum continuously decreases, with the continuous rotation of the rotor disc, the movable pendulum collides with the next counter-hammer again, the crossing angle between the movable pendulum and the fixed pendulum increases again, and so on, the crossing angle between the fixed pendulum and the movable pendulum changes in a cycle mode of continuously increasing-decreasing-increasing-decreasing, thereby continuously shearing the material entering between the fixed pendulum and the movable pendulum, so that the material is further broken, and the rotating driving mechanism only needs to control the rotor disc to rotate at a constant speed, thereby greatly simplifying the control process of the rotating driving mechanism and effectively reducing the cost of the equipment.

[0017] Further provided in the application is that a rubber pad is arranged on the surface of the end of the movable pendulum in contact with the counter-hammer.

[0018] By adopting the technical scheme, the rubber pad can protect the movable pendulum, thereby reducing the probability that the movable pendulum is damaged due to collision, greatly improving the practical service life of the equipment, and effectively reducing the noise generated by the collision between the movable pendulum and the counter-hammer.

[0019] Further provided in the application is that the pin shaft is located on the side of the diameter of the circumference of the rotor disc away from the rotation center, and the end of the movable pendulum close to the center of the rotor disc extends to the outer wall close to the center shaft.

[0020] By adopting the technical scheme, when the movable pendulum rotates around the pin shaft relative to the rotor disc, the end of the movable pendulum close to the center of the rotor disc continuously moves relative to the upper surface of the rotor disc, so that the material falling on the upper surface of the rotor disc is continuously pushed into the gap between the rotor disc and the inner wall of the barrel from the upper surface of the rotor disc, facilitating the full contact of the material with the movable pendulum and the fixed pendulum, effectively preventing the material from being accumulated on the rotor disc and causing the machine to be stuck, and realizing real-time automatic cleaning of the rotor disc without manual operation, thereby greatly reducing the labor cost.

[0021] Further provided in the application is that the pendulum mechanisms on the rotor discs are arranged in a staggered manner.

[0022] By adopting the technical scheme, the staggered arrangement can further improve the material breaking effect.

[0023] Further provided in the application is that the rotary driving mechanism comprises a rotary motor, the rotary motor is fixed outside the barrel through a motor support, a belt pulley is mounted on the output shaft of the rotary motor and the lower end of the rotating shaft, and the belt pulleys on the output shaft of the rotary motor and the central shaft are connected through a belt.

[0024] By adopting the technical scheme, when the rotary motor is started, the belt pulley on the output shaft of the rotary motor is synchronously rotated, the belt pulley on the output shaft of the rotary motor drives the central shaft to synchronously rotate through the belt when the belt pulley rotates, the central shaft drives the rotor disc fixedly connected thereto to synchronously rotate when the central shaft rotates, the rotor disc drives the pendulum mechanism to break the material in the barrel when the rotor disc rotates, and the rotary motor in the rotary driving mechanism and the central shaft are connected through the belt transmission, which not only has a simple structure, good stability and low noise, but also can prevent the weak parts from being damaged when the belt slips on the belt pulley, thereby playing a safety protection role and further ensuring the service life of the equipment.

[0025] The application has the following beneficial effects:

[0026] 1. The barrel with a "T"-shaped cylindrical structure can divide the breaking cavity into two parts with a large space in the upper part and a small space in the lower part, so that the large-sized power battery can be pre-broken (i.e., pre-cut) in the large space in the upper part after entering the breaking machine from the feeding port, and the smaller material obtained after pre-breaking can be further broken in the small space in the lower part, thereby effectively solving the problems of low breaking efficiency and machine sticking caused by the large volume of the material, and completing the twice breaking of the battery through only one operation, greatly simplifying the process of the breaking process, reducing the supporting equipment, and effectively reducing the energy consumption and enterprise equipment investment and operation cost.

[0027] 2. The pendulum mechanism in the application rotates with the rotor disc at high speed, the fixed pendulum and the movable pendulum in the pendulum mechanism constantly collide with the material in the barrel, thereby constantly breaking the material, at the same time, the fixed pendulum in the pendulum mechanism which is fixedly connected with the rotor disc rotates synchronously with the rotor disc, the movable pendulum in the pendulum mechanism which is rotatably connected with the rotor disc rotates around the pin shaft relative to the rotor disc and the fixed pendulum towards the side opposite to the rotor disc rotation direction under the action of inertia, the movable pendulum rotates to drive one end of the torsion spring to rotate synchronously, so that the torsion spring constantly accumulates elastic force, until the inertia force and the elastic force are equal, the movable pendulum rotates synchronously with the rotor disc, at this time, the fixed pendulum and the movable pendulum are in a crossed state, the greater the rotor disc speed, the greater the inertia force, the greater the rotation angle of the movable pendulum around the pin shaft, the smaller the rotor disc speed, the smaller the inertia force, the smaller the rotation angle of the movable pendulum around the pin shaft, therefore, when the rotary driving mechanism controls the rotor disc to rotate in the fast-slow-fast-slow cycle mode, the movable pendulum reciprocating rotates around the pin shaft relative to the rotor disc under the action of the inertia force and the torsion spring, thereby the crossing angle of the fixed pendulum and the movable pendulum is in the increasing-decreasing-increasing-decreasing cycle rotation state, the crossing angle of the fixed pendulum and the movable pendulum changes in the increasing-decreasing-increasing-decreasing cycle mode, in this process, the fixed pendulum and the movable pendulum constantly shear the material entering between the fixed pendulum and the movable pendulum, so that the material is further broken, greatly improving the breaking effect.
