[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 This utility model provides a technical solution: an environmentally friendly plastic granulator, comprising: a granulator body 1; a waste gas collection assembly 2 disposed on the granulator body 1 for collecting waste gas generated at the feed end and discharge end of the granulator body 1; a treatment box 3 disposed on one side of the granulator body 1, including a dust removal chamber 3-1 and a reaction chamber 3-2, wherein the reaction chamber 3-2 contains a reaction solution; a dust removal assembly 4 disposed in the dust removal chamber 3-1 for dust removal of the waste gas; an aeration assembly 5 connected to the outlet end of the dust removal chamber 3-1, and the aeration end extending into the reaction solution in the reaction chamber 3-2; and an atomizing spray assembly 6 disposed in the reaction chamber 3-1. 2. The upper end of the granulator body 1 is inserted into the reaction solution in the reaction chamber 3-2. During use, the waste gas collection component 2 collects waste gas from the feed end and discharge end of the granulator body 1, effectively preventing the direct emission of a large amount of waste gas generated during the hot melting process of the plastic granulator. The collected waste gas enters the treatment box 3 and is dusted by the dust removal component 4 in the dust removal chamber 3-1. The dusted waste gas reacts with the reaction solution through the aeration component 5 and is fully contacted with the waste gas through the atomizing spray component 6, ensuring that the toxic gases in the waste gas fully react with the reaction solution, avoiding the problem of affecting the health of the staff and polluting the environment.

[0022] Specifically, the exhaust gas collection assembly 2 includes a collection hood 2-1 respectively installed at the feed end and discharge end of the granulator body 1. The granulator body 1 is provided with a cavity 2-2. A first collection channel 2-3 is provided between the cavity 2-2 and the collection hood 2-1. An exhaust fan 2-4 is provided at the air outlet end of the cavity 2-2. A second collection channel 2-5 is provided between the air outlet end of the exhaust fan 2-4 and the treatment box 3. The second collection channel 2-5 is connected to the dust removal chamber 3-1. When in use, the exhaust fan 2-4 is started to generate negative pressure at the collection hood 2-1, so that a large amount of exhaust gas generated during the hot melting process of the plastic granulator body 1 is collected. The exhaust gas passes through the collection hood 2-1, the first collection channel 2-3, the cavity 2-2, and the second collection channel 2-5 in sequence and enters the dust removal chamber 3-1 in the treatment box 3. This realizes the collection of exhaust gas at the feed end and discharge end of the granulator body 1, effectively preventing the direct emission of a large amount of exhaust gas generated during the hot melting process of the plastic granulator.

[0023] Specifically, the dust removal assembly 4 includes a bag filter 4-1 disposed within the dust removal chamber 3-1. The bag filter 4-1 includes a partition located at the upper end of the dust removal chamber 3-1, with several filter bag frames on the partition. Dust removal filter bags are installed on the filter bag frames. A blowpipe adapted to the several dust removal filter bags is disposed at the upper end of the dust removal chamber. One end of the blowpipe extends out of the dust removal chamber and is equipped with an electromagnetic pulse valve. A compressed air tank connected to the electromagnetic pulse valve is disposed on the processing box 3. An activated carbon adsorption plate 4-2 is disposed at the top of the dust removal chamber 3-1, and a collection box 4-3 is disposed at the bottom of the dust removal chamber 3-1. The collection box 4-3 is detachably and sealed to the bottom of the dust removal chamber 3-1. In use, the bag filter 4-1 filters large particulate impurities in the exhaust gas. The filtered impurities enter the collection box 4-3 for collection. At the same time, the filtered exhaust gas is adsorbed by the activated carbon adsorption plate 4-2, thus realizing dust removal of exhaust gas through the dust removal assembly 4.

[0024] Specifically, the aeration assembly 5 includes a connecting pipe 5-1 connected to the dust removal chamber 3-1. The connecting pipe 5-1 is connected to the top of the dust removal chamber 3-1, and the bottom of the connecting pipe 5-1 extends into the reaction solution and is equipped with an aeration nozzle 5-2. The bottom of the connecting pipe 5-1 is equipped with a separator screen 5-3 that wraps around the outside of the aeration nozzle 5-2. In use, when the dust-removed exhaust gas enters the connecting pipe 5-1, it is aerated through the aeration nozzle 5-2 and enters the reaction solution in the reaction chamber 3-2. The separator screen 5-3 separates the larger bubbles generated by the aeration nozzle 5-2, avoiding insufficient reaction of the exhaust gas in the larger bubbles. By separating the larger bubbles, the separator screen 5-3 increases the contact area between the exhaust gas and the reaction solution, improves the reaction efficiency between the exhaust gas and the reaction solution, and improves the effect of exhaust gas treatment.

[0025] Specifically, the atomizing spray assembly 6 includes a serpentine coil 6-1 located at the upper end of the reaction chamber 3-2. The bottom of the serpentine coil 6-1 is provided with several evenly distributed atomizing nozzles 6-2. The evenly distributed atomizing nozzles 6-2 ensure that the reaction solution sprayed from the atomizing nozzles 6-2 fully covers the upper end of the reaction chamber 3-2. The inlet end of the serpentine coil 6-1 extends into the reaction solution and is equipped with an upper water pump 6-3. During use, the upper water pump 6-3 is activated, allowing the reaction solution in the reaction chamber 3-2 to enter the serpentine coil 6-1 through the upper water pump 6-3 and be sprayed out through the atomizing nozzles 6-2. The atomizing nozzles 6-2 spray the reaction solution into contact with the exhaust gas, effectively ensuring that the toxic gases in the exhaust gas fully react with the reaction solution, making the reaction more thorough and avoiding problems such as affecting the health of workers and polluting the environment.

[0026] Working principle: When the granulator body 1 is in operation, the waste gas collection component 2 is first activated to collect waste gas from the feed end and discharge end of the granulator body 1. The collected waste gas enters the treatment box 3 and is dusted by the dust removal component 4 in the dust removal chamber 3-1. The dusted waste gas reacts with the reaction solution through the aeration component 5 and is fully contacted by the atomizing spray component 6 to achieve waste gas treatment.
