Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, specifically to a crushing device for plastic particle processing. Background Technology

[0002] In the plastic recycling industry, crushing is a crucial process for handling recycled plastic materials and scraps. A typical crushing unit includes a feed inlet, a crushing chamber composed of crushing rollers, and a screening screen. After crushing, qualified particles are discharged through the screen. However, existing crushing units suffer from severe dust pollution during the feeding process. When dry plastic particles are fed at high speed through the inlet and violently impact the crushing rollers, a large amount of dust is generated. This dust not only diffuses outwards from the feed inlet, polluting the workshop environment and harming employee health, but also results in material waste.

[0003] Existing methods include installing a central dust collection system in the workshop or adding dust collection hoods and bag filters next to the equipment. This method is a form of "passive collection," where dust has already spread throughout the workshop, resulting in low dust removal efficiency, large equipment footprint, and high energy consumption. Some solutions attempt to spray water directly at the feed inlet or inside the crushing chamber. This method has low water utilization, the spray angle and volume are difficult to control, and it can easily cause materials to become too wet and sticky, affecting crushing efficiency and screening effect. Furthermore, the generated dusty wastewater flows everywhere, is difficult to collect, and can easily cause secondary pollution.

[0004] To address this, a crushing device for plastic particle processing is proposed, which can proactively suppress the generation and dispersion of dust from the very beginning of material input, achieving clean, environmentally friendly, and efficient continuous production. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a crushing device for processing plastic particles, which can actively suppress the generation and dispersion of dust from the initial stage of material input, thereby achieving clean, environmentally friendly, and efficient continuous production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a crushing device for processing plastic particles, comprising a device body, a screening box at the bottom of the device body, a vibration device on the outside of the screening box, a screening plate installed at an incline on the upper half of the screening box, a second discharge port at the bottom of the screening box, a first discharge port on the outside of the screening box, a dust collection box at the top of the device body, a water storage box above the dust collection box, a wastewater box connected to the bottom of the dust collection box via a pipe, an exhaust fan connected to the outside of the dust collection box via an air supply pipe, a filter chamber connected above the exhaust fan, a water pump connected to the outside of the water storage box, a diversion pipe installed below the water pump, and an atomizing nozzle installed at the bottom of the diversion pipe.

[0007] To facilitate crushing: As a further improvement to the above technical solution: a drive motor is provided on the outside of the device body, and the output end of the drive motor is connected to a crushing roller via a synchronous belt. There are two crushing rollers, and the crushing rollers are driven by gears.

[0008] The beneficial effects of this improvement are: the drive motor drives a crushing roller to rotate via a belt, and after gear transmission, the two crushing rollers rotate relative to each other, which can crush the raw materials.

[0009] To facilitate vibration of the screening box: As a further improvement to the above technical solution: the vibration device includes a telescopic cylinder, which is installed on the outside of the screening box, and guide rods are installed on both sides of the screening box. Guide sleeves are sleeved on the guide rods, and helical springs are installed inside the guide sleeves.

[0010] As a further improvement to the above technical solution: a sliding groove is provided on the main body of the device near the screening box, and the screening box and the main body of the device are connected by the sliding groove to form a locking and sliding installation structure.

[0011] The beneficial effects of this improvement are as follows: the telescopic cylinder is the vibration source, the telescopic cylinder pushes the screening box to move along the slide, the guide rod, together with the guide sleeve and the helical spring, guides and limits the screening box, and at the same time the helical spring can facilitate the vibration of the screening box.

[0012] To facilitate the collection of atomized droplets: As a further improvement to the above technical solution: the dust collector box is inclined, and through holes are opened at equal intervals at the bottom of the dust collector box.

[0013] The beneficial effects of this improvement are: the inclined dust collection box can facilitate the downward movement of atomized droplets along the dust collection box, and the through holes can facilitate the entry of gas and dust into the interior of the dust collection box.

[0014] To increase coverage: As a further improvement to the above technical solution: the diversion pipe is inserted and fixed to the top of the inner side of the dust collector box.

[0015] As a further improvement to the above technical solution: the atomizing nozzles are evenly distributed at the bottom of the diversion pipe.

[0016] The beneficial effect of this improvement is that the equally spaced atomizing nozzles can form a uniform water curtain inside the dust collection box.

[0017] As a further improvement to the above technical solution: a drainage pipe is installed at the bottom of the wastewater box.

[0018] The beneficial effects of this utility model are as follows: 1. The telescopic cylinder pushes the screening box to move along the chute, and the screening plate performs screening. Qualified particles are discharged through discharge port 2, and unqualified particles are discharged through discharge port 1, ensuring the efficiency and effect of screening.

[0019] Second, during the raw material crushing process, the water pump, in conjunction with the atomizing nozzle, forms an atomized water curtain. The exhaust fan draws air into the dust collection box, and the dust on the top of the device enters the dust collection box and comes into contact with the atomized water droplets. Wastewater flows into the wastewater box, and the remaining gas is filtered through the filter chamber before being discharged. This method can conveniently and quickly collect dust and prevent dust from escaping.

[0020] Third, the dust collection box, in conjunction with the water curtain, can collect most of the dust, reducing the burden on the filter chamber and thus effectively increasing its service life. Attached Figure Description

A screening plate 21 is installed at an angle on the upper half of the screening box 2, and a second discharge port 23 is located at the bottom of the screening box 2. A first discharge port 22 is installed on the outside of the screening box 2. A dust collector 3 is installed at the top of the device body 1, and a water storage box 31 is located above the dust collector 3. A wastewater box 32 is connected to the bottom of the dust collector 3 via a pipe. An exhaust fan 33 is connected to the outside of the dust collector 3 via an air supply pipe. A filter chamber 34 is connected above the exhaust fan 33. A water pump 35 is connected to the outside of the water storage box 31, and a diversion pipe 36 is installed below the water pump 35. An atomizing nozzle 37 is installed at the bottom of the diversion pipe 36. A drive motor 11 is installed on the outside of the device body 1, and the output end of the drive motor 11 is connected to a crushing roller 12 via a synchronous belt. There are two crushing rollers 12, and they are driven by gears. The drive motor 11 drives one crushing roller 12 to rotate via a belt. After gear transmission, the two crushing rollers 12 rotate relative to each other, which can crush the raw materials. The vibration device includes a telescopic cylinder 24, which is installed on the outside of the screening box 2. Guide rods 25 are installed on both sides of the screening box 2. Guide sleeves 26 are fitted onto the guide rods 25, and helical springs 27 are installed inside the guide sleeves 26. A sliding groove is provided on the device body 1 near the screening box 2, and the screening box 2 and the device body 1 are connected by the sliding groove to form a locking and sliding installation structure. The telescopic cylinder 24 is the vibration source. The telescopic cylinder 24 pushes the screening box 2 to move along the sliding groove. The guide rods 25, in conjunction with the guide sleeves 26 and the helical springs 27, guide the screening box 2. In addition to the limiting position, the helical spring 27 can facilitate the vibration of the screening box 2. The dust collection box 3 is inclined and has through holes at equal intervals at the bottom. The inclined dust collection box 3 can facilitate the downward movement of atomized droplets along the dust collection box 3. The through holes can facilitate the entry of gas and dust into the interior of the dust collection box 3. The diversion pipe 36 is inserted and fixed to the top of the inner side of the dust collection box 3. The atomizing nozzles 37 are evenly distributed at the bottom of the diversion pipe 36. The evenly distributed atomizing nozzles 37 can form a uniform water curtain inside the dust collection box 3. The bottom of the wastewater box 32 is equipped with a drainage pipe.

[0029] The working principle of this utility model is as follows: When using this device, the raw material enters the interior of the device body 1 through the top of the device body 1. The drive motor 11 drives the crushing roller 12 to rotate and crush the raw material. The crushed raw material falls onto the screen plate 21 inside the screen box 2. The telescopic cylinder 24 pushes the screen box 2 to move along the slide groove. The guide rod 25, together with the guide sleeve 26 and the spiral spring 27, guides and limits the screen box 2. At the same time, the spiral spring 27 facilitates the vibration of the screen box 2. The screen plate 21 screens the crushed raw material. Qualified particles are discharged through the discharge port 23, and unqualified particles are discharged through the discharge port 22. During the raw material crushing process, the water pump 35 pumps water from the storage box 3. Water in unit 1 is pumped to atomizing nozzle 37, where atomized water droplets move inside dust collection box 3. Exhaust fan 33 draws air from inside dust collection box 3, creating negative pressure inside. Dust on the top of unit 1 enters dust collection box 3 and comes into contact with atomized water droplets. The mass of the atomized water droplets in contact with dust increases, causing them to collect along dust collection box 3 and flow into wastewater box 32. The remaining gas and atomized water droplets are transported into filter chamber 34 by exhaust fan 33 for filtration and then discharged. This method can conveniently and quickly collect dust, preventing dust from escaping. With dust collection box 3 and water curtain, most dust can be collected, reducing the burden on filter chamber 34 and thus effectively increasing the service life of filter chamber 34.
