Abstract
Description
Technical Field
[0001] This utility model relates to the field of phenolic resin crushing technology, and in particular to a phenolic resin crushing device. Background Technology
[0002] In the industrial processing of phenolic resin, crushing is a crucial step. In the past, most crushing equipment adopted a single crushing mechanism, such as the common roller crusher, which relies on the relative rotation of two rollers to squeeze the resin block; or the cutting crusher, which uses rotating blades to cut the material. The significant drawbacks of this type of equipment are poor crushing efficiency and environmental performance: when dealing with large-sized phenolic resin raw materials, the processing speed is slow and it is difficult to meet the needs of large-scale production; at the same time, the large amount of dust generated during the crushing process lacks effective collection methods, which not only pollutes the workshop environment and harms the respiratory health of workers, but also causes raw material loss and increases production costs.
[0003] To address the shortcomings of traditional equipment, improved crushing devices with dust collection functions have emerged on the market. Some devices have a fixed dust collection port installed on the top of the crushing chamber, which, together with a negative pressure fan, sucks the dust into the dust collection box. Other devices adopt a "fully enclosed crushing chamber + multi-directional dust collection port" design, setting multiple dust collection points at the feed inlet, the side wall of the crushing chamber, and the discharge outlet. Through fan linkage, a three-dimensional negative pressure field is formed, which effectively adsorbs dust during the crushing and transmission process, significantly reducing the dust concentration in the workshop and improving the safety of the working environment.
[0004] However, these improved devices still have limitations: First, the fixed dust suction port design is difficult to adapt to the feeding conditions of materials of different specifications. When large pieces of raw materials enter the crushing chamber quickly, the high concentration of dust generated instantly can easily escape from the dust suction blind zone due to airflow disturbance. Second, when the multi-dust suction port negative pressure system is running, it will interfere with the material conveying in the crushing chamber, causing resin fragments to stagnate in the chamber and affecting the smoothness of discharge. Third, when the equipment is running, the high-frequency vibration of the crushing components and the resonance of the dust suction fan will aggravate the overall vibration amplitude of the equipment, which will not only reduce the crushing accuracy, but may also cause the dust suction pipe connection to loosen, resulting in dust leakage and further shortening the service life of the equipment.

[0025] Working principle: Phenolic resin raw material enters the crushing chamber 301 through the feed pipe 302. The operator starts the first motor 303 and the second motor 307 through the control panel 5, which drive the first crushing roller 306 and the second crushing roller 310 to rotate in opposite directions. The gap between the two rollers is used to squeeze and shear the material, completing the initial crushing. The material after initial crushing falls to the bottom of the crushing chamber 301 under the action of gravity. At this time, the third motor 311 is started, driving the crushing blade 314 on the outside of the third rotating shaft 313 to rotate at high speed, performing secondary cutting and crushing on the material. The material is processed to the required particle size. The inclined design at the bottom of the crushing box 301 allows the crushed material to be discharged through the feeding pipe 317. After crushing, the operator opens the control valve 318, and the material enters the feeding pipe 317 from the bottom of the crushing box 301. At the same time, the fourth motor 319 is started, driving the screw feeder 320 to rotate and conveying the material along the feeding pipe 317 to the next process. The sealing cover 321 on the right side of the feeding pipe 317 can be opened during equipment maintenance or cleaning to facilitate the removal of residual material inside the pipe. During equipment operation, the first dust extraction fan 402 and the second... Simultaneously, the first vacuum fan 402 creates a negative pressure area near the feed pipe 302 through the first connecting pipe 403, promptly adsorbing the dust generated during the feeding process. The dust is collected into the dust collection box 401 through the second connecting pipe 404. The second vacuum fan 406 creates a negative pressure above the feed pipe 317 through the third connecting pipe 407, drawing the dust raised during the feeding process into the dust collection box 401 through the fourth connecting pipe 408. The sealing door 405 at the right end of the dust collection box 401 facilitates periodic opening for cleaning the collected dust. The rubber sealing ring ensures... To ensure the airtightness of the dust collection box 401 and prevent dust leakage, when the equipment is running, the vibration generated by the crushing component and the dust collection component is transmitted to the shock absorption component 2 through the support block 1. The damper 203 and the spring 204 between the first base 201 and the second base 202 work together. The damper 203 effectively absorbs high-frequency vibration energy, while the spring 204 buffers the impact force and reduces the vibration amplitude. The rubber support pad 206 at the lower end of the support leg 205 further isolates the transmission of vibration to the ground, ensuring the stability of the equipment operation and reducing the loosening of parts and noise caused by vibration.
