Description

Technical Field

[0001] The utility model relates to the technical field of extruded board recycling, in particular to a device for recycling roughened waste materials of extruded boards. Background Art

[0002] Extruded board is a rigid foam plastic board made of polystyrene resin supplemented with polymer, which is injected with catalyst while heating and mixing, and then extruded to produce continuous closed-cell foaming. It has an independent closed bubble structure inside and is an environmentally friendly thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, super anti-aging (almost no aging after long-term use), and low thermal conductivity.

[0003] At present, when existing rapid boards are recycled, they are mostly crushed by hammer mills and knife mills and then recycled. However, a large amount of dust will be generated in the specific crushing process, which has an adverse effect on the operating environment and personnel health. The current solution is to install an air pump in the device to absorb the generated dust downwards, but the dust will be absorbed by the filter plate on the air inlet of the air pump. The blockage will reduce the suction force of the air pump and cause some dust to float outward. Therefore, it is necessary to redesign the device for recycling extruded board roughening waste in view of the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 , a device for recycling waste materials of extruded board roughening, comprising a recycling box 1, the upper end of the recycling box 1 is in an open state, a recycling groove 2 is opened on the side wall of the recycling box 1, a door panel 3 is rotatably connected to the recycling groove 2, the recycling groove 2 is communicated with the inside of the recycling box 1, two sets of knife-type crushing rollers 7 are rotatably connected in the recycling box 1, and the positions are symmetrical to each other, a reciprocating screw 9 is rotatably connected to the inner wall of the recycling box 1, the reciprocating screw 9 is connected to a scraper 13 through a connecting mechanism, an air pump 8 is fixedly connected to the side wall of the recycling box 1, an air inlet of the air pump 8 is communicated with the inside of the recycling box 1, a filter plate 12 is installed at the air inlet of the air pump 8, and the scraper 13 is slidably connected to the outer wall of the filter plate 12;

[0021] With the help of the setting of the filter plate 12, dust can be prevented from directly entering the air pump 8 and causing damage to the operation of the air pump 8. With the help of the rapid sliding of the scraper 13, the dust attached to the outer wall of the filter plate 12 can be quickly scraped off, thereby avoiding dust clogging to reduce the suction force of the air pump 8, improving the dust suction force, and preventing dust from drifting outward.

[0022] Reference Figure 2 and Figure 3 , the connecting mechanism includes a screw sleeve 14 threadedly connected to the threaded section of the reciprocating screw 9, a scraper 13 fixedly connected to the outer wall of the screw sleeve 14, two groups of limit blocks 11 are fixedly connected to the outer wall of the reciprocating screw 9, and the positions are symmetrical, the spacing between the two groups of limit blocks 11 is consistent with the diameter of the filter plate 12, the inner wall of the recovery box 1 is fixedly connected to the limit rod 10, the screw sleeve 14 is slidably connected to the outer wall of the limit rod 10, the outer wall of the recovery box 1 is rotatably connected to the transmission wheel 14 and the transmission wheel 2 5, the transmission wheel 14 and the transmission wheel 2 5 are connected by a transmission belt 6, the transmission wheel 14 is coaxially fixedly connected to the reciprocating screw 9, the transmission wheel 2 5 is coaxially fixedly connected to the adjacent knife-type crushing roller 7, and the radius of the transmission wheel 2 5 is greater than the radius of the transmission wheel 1 4;

[0023] With the cooperation of the transmission wheel 1 4 and the transmission wheel 2 5, the reciprocating screw 9 can be synchronously driven to rotate through the rotation of the knife-type crushing roller 7. The transmission wheel 1 4 is set to be smaller than the radius of the transmission wheel 2 5, so that the reciprocating screw 9 is accelerated when driven to rotate, thereby realizing the rapid scraping of the scraper 13.

[0024] In the utility model, the specific function of the device is: when using the device, the extruded board roughening waste can be cut by rotating two sets of knife-type crushing rollers 7, and the air pump 8 is started during the cutting process. The suction force generated by the air pump 8 can make the dust generated during cutting float downward, thereby avoiding adverse effects on the operating environment and personnel health. During the rotation of the knife-type crushing roller 7, the transmission wheel 1 4 and the transmission wheel 2 5 can be used to synchronously drive the reciprocating screw 9 to rotate, and then the screw sleeve 14 on the thread drives the scraper 13 to slide back and forth on the outer wall of the filter plate 12. During the sliding, the dust attached to the outer wall of the filter plate 12 can be scraped off, thereby avoiding the dust adsorbed on the outer wall of the filter plate 12, resulting in a reduction in the adsorption force of the air pump 8, thereby ensuring that the dust does not float upward.
