Description

Technical Field

[0001] The utility model relates to the technical field of waste circuit board recycling, and specifically relates to a waste circuit board crushing and automatic sorting powder device. Background Art

[0002] Waste circuit boards, also known as used circuit boards, refer to the circuit boards that have been discarded in computers, communications, and other electronic devices. Waste circuit boards have high recycling value because they contain a large amount of precious metals and noble metals (such as gold, silver, copper, palladium, etc.). The recycling and treatment of waste circuit boards is an important environmental protection and economic measure. Through reasonable recycling and utilization, environmental pollution can be greatly reduced, while resource recycling can be achieved, creating economic value. The recycling and treatment methods include high-temperature melting method, chemical treatment method, biological treatment method, physical method, etc. Among them, the physical method can utilize the differences in physical properties such as the density, particle size, conductivity, magnetic permeability, and surface characteristics of materials, and separate the metal and non-metal parts of the waste circuit board through processes such as crushing, grinding, and sorting.

[0003] For example, the existing patent publication number CN217940304U provides a waste circuit board crushing and automatic sorting powder device, which relates to the technical field of waste circuit board recycling. To solve the problems that when taking larger waste circuit boards in the existing crushing and screening device, the operation is very inconvenient, it is not easy to clean the large waste circuit boards on the screen, and the large waste circuit boards are also easy to block the screen mesh holes, reducing the screening efficiency of the device. A fixed ring is fixed at the upper end inside the processing box. The bottom of the fixed ring is fixedly arranged with vibration springs in an array. The lower ends of the vibration springs are fixed with a vibration ring. The inner wall of the vibration ring is fixedly provided with a funnel-shaped screen frame. The lower inner wall on both sides of the funnel-shaped screen frame is provided with a rotating plate. The rotating plate is rotationally connected with the funnel-shaped screen frame through a torsion spring. A material taking window is embedded along the lower end of the rotating plate on the front side of the processing box. The material taking window is matched with a collection box. A vibration mounting plate is fixed along the lower part of the vibration ring on the inner wall of the processing box.

[0004] In the above solution, through the mutual cooperation between the collection box and the winding motor, the larger circuit board crushing blocks that cannot sink above the screen are collected and crushed again, increasing the crushing and sorting effect of the device on the circuit board. In this process, inserting and removing the collection box and the collection process of the circuit board fragments need to be coordinated with the opening and closing of the winding motor, which requires more operation steps, and it is not easy to observe the accumulation degree of the fragments on the screen plate. Therefore, it is not easy to control the interval of taking fragments by the collection box.

[0005] Therefore, a waste circuit board crushing and automatic sorting powder device is proposed for the above problems. Summary of the Utility Model

[0006] In order to make up for the shortcomings of the existing technology, a waste circuit board crushing and automatic powder sorting device is proposed to solve the problems that the insertion and removal of the collection box and the opening and closing of the reeling motor are required to cooperate with each other during the collection of circuit board fragments, which requires more operating steps, and the accumulation state of the fragments on the screen plate is not easy to observe, so it is not easy to control the interval between the collection box and the fragments.

The auger body continues to rotate to discharge the debris that does not meet the standard. When the collection box is about to reach the collection upper limit, the debris in the collection box only needs to be discharged into the crushing device in the shell for re-crushing, and the process of inserting the collection box into the device at intervals is omitted, thereby increasing the practicality of the device.

[0016] 2. In the utility model, the motor body provides a rotational output force to the auger body through the connection between its output shaft and the auger body, and the motor bracket for mounting the motor body is installed at one end of the auger mounting sleeve, so that the vibration generated during the rotation of the motor body can make the inclined screen plate have a vibration effect as a whole, thereby preventing debris from accumulating on the inclined surface.

One end of the springs 13 on both sides is vertically fixed to the top and bottom surfaces of the auger mounting sleeve 21 respectively. The circuit board debris that is crushed and gradually sinks in the shell 1 is filtered through the inclined screen plate 2, and the debris that meets the screening standard continues to sink to the sorting step, and the debris that does not meet the standard moves along the inclined surfaces on both sides of the inclined screen plate 2 to the inside of the auger mounting sleeve 21. The auger body 3 is installed inside the inclined screen plate 2 with the cooperation of the fixed cross plate 31. After the debris sinks into the inclined screen plate 2, it is discharged from the discharge sleeve 23 through the transfer ring 22 under the rotation of the auger body 3 inside. The shell 1 limits the position of the inclined screen plate 2 through the mutual cooperation between the spring 13 on the limit frame 12 and the auger mounting sleeve 21, so that the inclined screen plate 2 as a whole can vibrate upward within a certain range;

[0028] like Figure 4 and Figure 5As shown, a motor bracket 24 is fixedly connected to the lower side of one end of the auger mounting sleeve 21. The motor body 4 is mounted on the top of the motor bracket 24 through the bracket. The output shaft of the motor body 4 is fixedly connected to the shaft rod of the auger body 3. The auger mounting sleeve 21 mounts the motor body 4 through the motor bracket 24. The motor body 4 provides a rotational output force for the auger body 3.

The auger body 3 is installed inside the inclined sieve plate 2 through the cooperation of the fixed cross plate 31. After the debris sinks into the inclined sieve plate 2, it is discharged from the feeding sleeve 23 through the transfer ring 22 under the rotation of the auger body 3 inside it. Among them, the housing 1 limits the position of the inclined sieve plate 2 through the mutual cooperation between the spring 13 on the limit frame 12 and the auger mounting sleeve 21, so that the whole inclined sieve plate 2 can vibrate upward within a certain range. The auger mounting sleeve 21 mounts the motor body 4 through the motor bracket 24. The motor body 4 provides a rotational output force for the auger body 3. During the startup process of the motor body 4, the generated vibration can make the inclined sieve plate 2 as a whole have a certain vibration force. The inclined wall guiding frames 5 guide and collect the debris discharged from the feeding sleeves 23, so that the debris finally converges inside the collection box 61. When the debris in the collection box 61 accumulates to a certain amount, it is removed from the box body frame 6, and the debris in the collection box 61 is discharged into the housing 1 again to lose the inside of the device and is crushed again.
