Description

Technical Field

[0001] The present application relates to the technical field of extruders, and in particular to a plastic extruder with a waste gas treatment function. Background Art

[0002] A plastic extruder is a device that processes plastic powder or plastic granules into plastic tubes. It uses a screw of a specific shape to rotate in a heated barrel to extrude the plastic sent from the hopper forward, plasticize (i.e. melt) the plastic evenly, and extrude the plastic into continuous plastic layers or plastic tubes of various required shapes through a machine head and molds of different shapes.

[0003] In the current processing, plastics must be melted and then processed, which produces some harmful gases. Traditional plastic extruders allow the gases to diffuse into the air, affecting and endangering the health of workers. The existing waste gas treatment device extracts the waste gas from the plastic extruder. After a long period of work, a large amount of oily organic matter will adhere to the inside of the waste gas treatment device, and the oily organic matter in the waste gas is not easy to be cleaned.

At this time, the oil and other substances contained in the exhaust gas will be covered in the water droplets. The water droplets flow into the water channel and merge with the water in the water channel, so that the oil and other substances float on the water surface. The water flow in the water channel drives the movement of the oil and substances and makes them contact with the collection membrane. The collection membrane intercepts and adheres to the oil and substances, thereby facilitating the exhaust gas cleaning process.

[0010] Optionally, a driving fan is fixed to the inner side wall of the main pipe.

[0011] By adopting the above technical solution, a driving fan is fixed to the inner wall of the main pipe. When the driving fan is started, the exhaust gas in the exhaust pipe can enter the collection box more quickly, which is convenient for the subsequent cleaning process.

[0012] Optionally, limiting blocks are detachably connected to both sides of the collection membrane, a positioning block is fixed to the inner side wall of the water passage, and a limiting groove for passing the limiting block is opened on the positioning block.

[0015] By adopting the above technical solution, the locking block is inserted into the locking groove, and the collecting membrane is synchronously fixed in the locking groove during the insertion process, thereby completing the fixation of the collecting membrane, reducing the possibility of the collecting membrane detaching from the limiting block, and improving the stability of the collecting membrane.

[0016] Optionally, the cooling device includes a compressor, a condenser, a throttling tube, an evaporator, etc., and they are all fixed to the side wall of the collection box.

[0023] 1. Exhaust gas enters the collection box through the exhaust pipe. Under the action of the cooling device, the exhaust gas is cooled and condensed into small particles of water droplets. At this time, the oil and other pollutants contained in the exhaust gas will be wrapped in the water droplets. The water droplets flow into the water channel and merge with the water in the water channel, so that the oil and pollutants float on the water surface. The water flow in the water channel drives the oil and pollutants to move and contact with the collection membrane.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a plastic extruder with waste gas treatment function. Figure 1 , Figure 2 and Figure 3The plastic extruder with waste gas treatment function includes a machine body 1, which is used to process plastic raw materials. An exhaust pipe 2 is connected to the machine body 1, and the exhaust pipe 2 is used to discharge the waste gas generated inside the machine body 1 during the processing of the machine body 1. A collecting box 3 is fixed on the ground by bolts. The exhaust pipe 2 is connected to the collecting box 3. A cooling device 4 is arranged in the collecting box 3. The cooling device 4 is used to cool the waste gas and condense the waste gas into water droplets. A water passage 5 is fixed to the bottom of the collecting box 3 by bolts. The water passage 5 is used to collect the water droplets condensed by the waste gas, so as to facilitate its collection and treatment.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The exhaust pipe 2 includes a plurality of branch pipes 7 and a main pipe 8. The plurality of branch pipes 7 are all connected to the machine body 1, and the plurality of branch pipes 7 are evenly distributed along the length direction of the machine body 1. The plurality of branch pipes 7 are simultaneously connected to the main pipe 8, and the main pipe 8 is simultaneously connected to the collecting box 3, so that the branch pipes 7 can transfer the exhaust gas to the main pipe 8 and thus to the collecting box 3 after collecting the exhaust gas; at the same time, a driving fan 9 is fixed to the inner side wall of the main pipe 8 by bolts, and the rotation of the driving fan 9 can accelerate the transfer of the exhaust gas in the main pipe 8 and the branch pipe 7 to the inside of the collecting box 3, thereby facilitating the exhaust gas collection and treatment process.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A collecting membrane 6 is detachably connected to the water passage 5, and limiting blocks 10 are detachably connected on both sides of the collecting membrane 6. A plurality of positioning blocks 11 are fixed to the inner wall of the water passage 5. The plurality of positioning blocks 11 are grouped into two and are evenly distributed along the length direction of the water passage 5. A limiting groove 12 is provided on the positioning block 11, and the limiting groove 12 is used to penetrate the limiting block 10, so as to fix the position of the limiting block 10 and the position of the collecting membrane 6. Water is placed in the water passage 5, and the water can flow in the water passage 5. After the exhaust gas condenses into water droplets, it flows into the water passage 5 and moves driven by the water in the water passage 5. Since the oil will float on the water surface after the exhaust gas condenses, and the collecting membrane 6 is partially in contact with the water surface, during the movement of water in the water passage 5, the liquid carries the oil to move, so that the oil is transferred to the collecting membrane 6, thereby completing the collection and treatment of the exhaust gas.

[0034] Reference Figure 1 , Figure 2 and Figure 3The side wall of the limit block 10 is rotatably connected with a locking plate 13 through a rotating shaft. A plurality of locking blocks 14 are fixed on the end surface of the limit block 10 by an integrated molding method. A plurality of locking grooves 15 are provided on the side wall of the limit block 10. The plurality of locking grooves 15 correspond to the plurality of locking blocks 14 one by one. The locking blocks 14 are penetrated into the locking grooves 15, thereby fixing the collecting membrane 6 and completing the positioning of the collecting membrane 6; it is convenient to disassemble the collecting membrane 6 so as to clean the oil stains on the collecting membrane 6. At the same time, an installation guide surface 17 is provided at the end of the locking block 14, and the installation guide surface 17 facilitates the locking block 14 to penetrate into the locking groove 15, thereby facilitating the fixing process of the collecting membrane 6.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The cooling device 4 includes a compressor, a condenser, a throttling tube, an evaporator, etc., and its composition structure is an existing structure on the market, and they are all fixed to the side wall of the collecting box 3 by bolts, which is convenient for refrigerating the inside of the collecting box 3, so that the exhaust gas in the collecting box 3 is quickly condensed into water droplets, which are attached to the inner wall of the collecting box 3 and transferred to the water passage 5, which is convenient for the exhaust gas collection and treatment process; at the same time, a plurality of runners 16 are connected to the water passage 5 by a rotating shaft, and the plurality of runners 16 are evenly distributed in the water passage 5, and are driven to rotate by a motor placed outside the water passage 5. The motor shaft and the runner 16 shaft are connected by a gear transmission, so that after the motor is started, the motor shaft rotates to drive the runner 16 to rotate, thereby causing the water in the water passage 5 to flow, which is convenient for transferring the water collected in the collecting box 3 into water droplets condensed from the exhaust gas to the outside of the collecting box 3.

[0036] The implementation principle of a plastic extruder with a waste gas treatment function in an embodiment of the present application is as follows: the waste gas condenses into water droplets and flows into the water channel 5, and moves driven by the water in the water channel 5. Since the oil pollution will float on the water surface after the waste gas condenses, and the collection membrane 6 is partially in contact with the water surface, during the movement of water in the water channel 5, the liquid carries the oil pollution and transfers the oil pollution to the collection membrane 6, thereby completing the collection and treatment of the waste gas.
