Description

Technical Field

[0001] This invention relates to the field of crushing and separation technology, specifically to a crushing and separation device for waste electronic components. Background Technology

[0002] Waste electronic components are the components of electronic parts and small machines and instruments. They are often composed of several parts and can be used in similar products. With the rapid development of science, the amount of electronic component waste has also increased. In order to reduce the environmental impact of electronic component waste, the recycling of electronic components has been promoted. After recycling, electronic components need to be crushed and separated to obtain plastic powder and metal powder.

[0003] Existing waste electronic component crushing and separation devices struggle to ensure uniformity and efficiency in crushing waste electronic components of varying shapes and sizes, resulting in suboptimal crushing effects. Furthermore, the lack of effective guidance during material feeding leads to blockages and hinders smooth material flow. Initial screening lacks effective methods for separating plastic fragments and particles of different sizes, making preliminary plastic classification and collection difficult. Insufficient mixing of the crushed materials results in poor separation, failing to effectively separate plastic particles from metal powder. Metal powder collection lacks effective adsorption structures, leading to incomplete collection and low resource recovery rates. During collection, metal powder is easily dispersed, causing environmental pollution, significant powder loss, and low recovery rates, while also being inconvenient and hindering subsequent processing and recycling. Therefore, corresponding technical solutions are needed to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a waste electronic component crushing and separation device, which solves the technical problems.

A blower plate is fixedly installed at the bottom of the drive shaft, and air heads are fixedly distributed at the bottom of the blower plate; The air generated by the fan enters the blower plate through the channel and slot, and is then blown out by the fan head. The rotational relationship between the shaft collar and the drive shaft is used to achieve stable air delivery. The shaft cylinder stably supports the rotation of the drive shaft, and the control motor and drive shaft are used to drive and control the rotation adjustment of the blower plate.

[0009] Preferably, a collar is rotatably connected to the outside of the drive shaft, and crossbars are fixedly distributed on the outer side wall of the collar. A channel is opened inside one of the crossbars. Through slots are opened horizontally and downward in the collar and towards the lower end of the drive shaft and the inside of the blower plate. A fan is fixedly installed at the front end of the feeding and separating mechanism, and the inner end of the fan is connected to the outer end of the channel. Multiple crossbars are used to support the high-strength shaft collar, which in turn provides stable support for the drive shaft rotation and prevents it from wobbling.

[0010] Preferably, the feeding and separating mechanism has an opening on its side, an extension frame is fixed at the outer end of the opening, a metal powder collecting frame is provided below the outside of the extension frame, and the inner end of the metal powder collecting frame is fixed to the side of the plastic feeding port via a connecting plate. The metal powder collection frame is located below the outer end of the extension frame to collect metal powder.

[0011] Preferably, the upper and lower sides of the extension frame are provided with a pressing and blocking structure. The pressing and blocking structure includes an electric push rod device, a pressure plate and a push rod. The pressure plate is slidably connected to the upper and lower sides of the extension frame. The push rod is fixed at the middle of the outer end of the pressure plate. The electric push rod device is connected to the outer end of the push rod. The electric push rod device is fixed to the outer wall of the material feeding and separating mechanism. The electric push rod device has extension plates fixed on both sides, and an auxiliary rod is slidably connected through the inside of the extension plates. The auxiliary rod is fixed to the outer end of the pressure plate. The pressing and shielding structure is a double-unit structure located above and below the extension frame. The electric push rod device and push rod are used to adjust the position of the pressing plate by telescopic adjustment, so that the pressing plate slides and adjusts above and below the extension frame to seal and press against the upper and lower ends of the adsorption plate, avoiding material leakage during mixing and stirring in the separation process. The limiting sliding of the extension plate and auxiliary rod makes the telescopic adjustment of the pressing plate more stable.

[0012] Preferably, a metal powder telescopic adsorption structure is connected through the middle of the interior of the extension frame. The metal powder telescopic adsorption structure includes a ring plate frame, an adsorption plate, an electro-hydraulic device, and a limiting block. The limiting block is fixed at both ends of the interior of the extension frame. Limiting plates are fixed on both sides of the adsorption plate and are slidably connected to the interior of the limiting block.

When the adsorption plate extends into the interior, it is used to adsorb metal powder. After it is removed, it is used to release the metal powder through the cooperation of the pressure plate and collect it into the metal powder collection frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: by connecting the crushing toothed roller inside the crushing box, the drive system drives the movable shaft and the crushing toothed roller to rotate stably at high speed, so as to efficiently crush the waste electronic components entering the crushing box, effectively crush waste electronic components of different shapes and sizes, and improve the uniformity and efficiency of crushing.

[0014] By using a sloping feeding channel that is fixedly connected to the lower end of the crushing box, the crushed material can smoothly slide down to the feeding and separation mechanism by its own gravity, avoiding blockage during the feeding process and ensuring smooth feeding.

[0015] By fixing a plastic feeding port at the lower end of the feeding and separating mechanism and a filter plate at the upper end of the plastic feeding port, a preliminary screening function is achieved. Larger plastic fragments after crushing are intercepted and left in the feeding and separating mechanism for further separation, while smaller plastic particles fall into the plastic feeding port through the filter plate, thus achieving preliminary classification and collection of plastics.

[0016] By connecting the mixing structure through the middle of the upper end of the feeding and separation mechanism, the blowing plate and multiple blowers rotate stably, effectively stirring and mixing the crushed materials, resulting in better separation. The blower connected through the blowing plate and blowers above the blowers can blow air onto the materials in the feeding and separation mechanism from all directions, further improving separation efficiency and more effectively separating different materials, making the separation of plastic particles and metal powder more thorough and improving the separation effect.

[0017] By using a metal powder telescopic adsorption structure installed inside the extension frame at the outer end of the side opening of the feeding and separation mechanism, the electro-hydraulic device pushes the adsorption plate to telescopically move within the extension frame via a hydraulic rod. The adsorption plate can adsorb the metal powder within the extension frame, further improving the metal powder collection effect, enabling more thorough collection of metal powder, and increasing the resource recycling rate.

[0018] By using a pressing and shielding structure set above and below the extension frame at the outer end of the side opening of the feeding and separating mechanism, an automated electric push rod device pushes the pressure plate towards the extension frame before metal powder collection, sealing and pressing the pressure plate, reducing the flying of metal powder, improving the environmental quality of metal powder collection, reducing metal powder loss, and increasing the recovery rate; and by setting a metal powder collection frame, the metal powder falls into the metal powder collection frame, which can be easily collected, facilitating subsequent processing and recycling.

The electric push rod device 381 and push rod 385 are used to adjust the position of the pressure plate 382, ​​so that the pressure plate 382 is slidably adjusted above and below the extension frame to seal and press against the upper and lower ends of the adsorption plate 372, so as to avoid material leakage during mixing and stirring in the separation process. The limiting sliding of the extension plate 383 and the auxiliary rod 384 makes the pressing plate 382 more stable in its telescopic adjustment.

[0029] Specifically, the extension frame is internally connected to a metal powder telescopic adsorption structure 37. The metal powder telescopic adsorption structure 37 includes a ring plate frame 371, an adsorption plate 372, an electro-hydraulic device 373, and a limiting block 375. The limiting block 375 is fixed to both ends of the extension frame. Limiting plates 376 are fixed to both sides of the adsorption plate 372. The limiting plates 376 are slidably connected to the inside of the limiting block 375.

The hydraulic rod 374 is fixed to the middle of the outer end of the adsorption plate 372. Limiting rods 377 are fixed to both ends of the outer side of the adsorption plate 372. The limiting rods 377 are slidably connected to the inside of the ring plate frame 371. The ring plate frame 371 is fixed to the outer side of the feeding and separating mechanism 31 in a frame-like structure. The electric hydraulic device 373 and the hydraulic rod 374 are used to extend and retract to adjust the position of the adsorption plate 372. When the adsorption plate 372 extends into the interior, it is used to adsorb metal powder. After it is removed, it is used to release the metal powder through the cooperation of the pressure plate 382 and collect it into the metal powder collection frame 33.

[0030] Working principle: Move the waste electronic component crushing and separation device to a suitable working position, and move and position the device by pushing the push rod frame 22 on the vehicle body 2 and using the moving wheels 21 at the bottom corner of the vehicle body 2; The waste electronic components to be processed are put into the crushing box 1 through the feed port 12 at the upper side of the crushing box 1; Start the drive motor 14, which drives the drive shaft disk 141 to rotate. The drive shaft disk 141 drives the fixed shaft disk 142 to rotate via a belt, which in turn drives the movable shaft 11 to rotate stably within the shaft seat 112. The crushing toothed roller 111 in the middle of the movable shaft 11 then rotates at high speed to crush the waste electronic components that have entered the crushing box 1. The crushed material, relying on its own gravity, slides smoothly into the feeding separation mechanism 31 through the feeding channel 3, which is fixed at the lower end of the crushing box 1 in an inclined channel, thus avoiding blockage during the feeding process and ensuring smooth feeding. After the material enters the feeding and separation mechanism 31, the filter plate 321 at the upper end of the plastic feeding port 32 plays a preliminary screening role. The plastic powder falls into the plastic feeding port 32 through the filter plate 321, realizing the preliminary classification and collection of plastic. The control motor 34 is started, which drives the drive shaft 343 to rotate inside the shaft cylinder 342. The blower plate 361 fixed at the bottom of the drive shaft 343 rotates stably accordingly. The blowers 362 fixedly distributed at the bottom of the blower plate 361 effectively stir and mix the material in the feeding and separating mechanism 31. At the same time, the blower 36 is started. The air generated by the blower 36 enters the blower plate 361 through the channel 352 located inside a crossbar 35, the horizontal and downward passage inside the shaft ring 351 and the through groove 3510 opened inside the blower plate 361, and is then blown out from all directions by the blowers 362 to separate the material by blowing air, further improving the separation efficiency and making the plastic powder and metal powder more thoroughly separated. Start the electro-hydraulic device 373, which pushes the adsorption plate 372 to extend and retract within the extension frame via the hydraulic rod 374; the adsorption plate 372 extends into the feeding and separating mechanism 31 to adsorb the metal powder inside. Before collecting metal powder, the electric push rod device 381 is activated. The electric push rod device 381 pushes the pressure plate 382 to move towards the extension frame through the push rod 385. The pressure plate 382 slides and adjusts above and below the extension frame, so that the pressure plate 382 stably seals and presses the adsorption plate 372, reducing the flying of metal powder, improving the environmental quality of metal powder collection, and reducing the loss of metal powder. The electric hydraulic device 373 is restarted, and the adsorption plate 372 containing metal powder is moved out of the extension frame by the hydraulic rod 374. With the cooperation of the pressure plate 382 of the pressing and shielding structure 38, the adsorption plate 372 releases the metal powder, which falls into the metal powder collection box 33 below the outside of the extension frame, facilitating the subsequent processing and recycling of the metal powder.
