Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to a waste gas treatment device for plastic pellet production. Background Technology

[0002] The recycling of waste plastics has become a trend. Recycling, washing, and granulating waste plastics is a way to turn waste into treasure and reuse resources. However, during the recycling and granulation process, when the temperature exceeds 200℃, the plasticizer and the low-boiling-point impurities inside will undergo oxidative decomposition, producing a large amount of harmful gases containing dust particles. Therefore, it is necessary to use it in conjunction with a waste gas treatment device for plastic granule production.

[0003] According to the patent application CN213995288U, a waste gas treatment device for plastic granule production is disclosed online, which includes an impurity separation chamber, an air inlet, an induced draft fan, a photolysis chamber, a low-temperature plasma purification chamber, a cyclone spray chamber, and air pipes. The air inlet is located on the top wall of the impurity separation chamber, and the induced draft fan is located at the end of the air inlet. The cyclone spray chamber has a cylindrical hollow cavity structure. The air pipes are evenly distributed at the connections between the impurity separation chamber and the photolysis chamber, the photolysis chamber and the low-temperature plasma purification chamber, and the low-temperature plasma purification chamber and the cyclone spray chamber. This utility model belongs to the field of plastic product processing technology, specifically referring to a waste gas treatment device for plastic granule production that adsorbs and discharges particulate impurities in the early stage, performs multi-stage purification on the discharged waste gas, and improves the purification efficiency.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model uses an induced draft fan to draw exhaust gas into the inlet for convenient subsequent purification. An impurity separation chamber allows an electromagnetic coil to adsorb impurity particles from the exhaust gas, and an electromagnetic valve controls the opening and closing of the filter port to discharge these particles. However, in actual use, the connection between the inlet and external equipment relies solely on a plug-in connection, which can easily lead to loosening or other unexpected situations. Furthermore, the device requires shutdown when discharging solid waste, affecting purification efficiency. Therefore, an improved exhaust gas treatment device for plastic granule production is needed to address these issues. Utility Model Content

[0032] Furthermore, the mounting assembly 81 includes a clamping platform 811, which is fixedly connected to the outside of the air inlet pipe 6. A button 812 is slidably connected inside the clamping platform 811, and a first spring 815 is fixedly connected inside the clamping platform 811. An elastic clamping block 814 is fixedly connected to the end of the first spring 815 away from the clamping platform 811, and a sliding rod 813 is fixedly connected to the end of the elastic clamping block 814 near the first spring 815, so as to facilitate the adjustment of the opening and closing degree of the elastic clamping block 814 to satisfy the limiting connection between the air inlet pipe 6 and the exhaust pipe of the plastic pellet production equipment.

[0033] Furthermore, the clamping platform 811 has a groove at the corresponding position of the slide bar 813, and the slide bar 813 is slidably connected inside the groove. The button 812 contacts the elastic clamping block 814, which makes the installation process more stable.

[0034] Furthermore, the adjustment assembly 82 includes a connecting platform 821, which is fixedly connected to the inside of the intake pipe 6.

[0036] Example 2:

[0037] Based on Embodiment 1, the prior art requires a shutdown operation when discharging solid waste, thus affecting purification efficiency. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 6-7Furthermore, in conjunction with Embodiment 1, the filter collection mechanism 9 includes a filter collection frame 91, which is movably connected inside the connecting box 7. A limiting box 92 is fixedly connected to the outside of the filter collection frame 91. A second spring 95 is fixedly connected inside the limiting box 92.

[0039] In actual operation, when this device is used, firstly, the air inlet pipe 6 is connected to the exhaust pipe of the plastic granule production equipment. The operator presses button 812, and the movement of button 812, in conjunction with the elastic clamp 814 and the first spring 815, causes the slide rod 813 to slide inside the clamping table 811, thereby adjusting the opening and closing degree of the elastic clamp 814. After connection, the set induced draft fan 2 works to draw in air, and the set photolysis chamber 3 works to carry out photo-oxidation catalytic reaction to decompose harmful gases. The set low-temperature plasma purification chamber 4 works to efficiently decompose pollutant molecules with low energy consumption. The cyclone spray chamber 5 purifies the gas by filtering solid impurities in the exhaust gas through the filter collection frame 91. When the filter collection frame 91 needs to be cleaned, the operator rotates the threaded rod 822. The rotation of the threaded rod 822, in conjunction with the limit rod 827, causes the movable frame 823 to move, which in turn causes the toothed plate 824 to move. In conjunction with the gear 826, the baffle 825 rotates inside the air inlet pipe 6. The operator pulls the sliding plate 96. The movement of the sliding plate 96, in conjunction with the second spring 95, causes the locking block 94 to move. In conjunction with the fixing block 93, the filter collection frame 91 is limited to the connecting box 7.
