[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This utility model discloses a polymer material internal mixer, such as Figures 1-5 As shown, it includes a workbench 1, a catalytic burner 10, and a machine body 2 fixedly installed on the left side of the outer top surface of the workbench 1 for processing polymer materials.

[0024] A processing box 3 is fixedly installed on the right side of the outer top surface of the workbench 1, and an exhaust fan 4 is fixedly installed on the outer top surface of the processing box 3. The exhaust fan 4 uses the centrifugal force generated by the rotation of the impeller to throw out the gas and form a low-pressure zone to draw in the gas. The exhaust fan 4 is powered by an external power source.

[0025] The inlet of the exhaust fan 4 is fixedly installed with a connecting pipe 5, and the connecting pipe 5 is fixedly connected to the bottom right side of the outer surface of the treatment box 3. The bottom right side of the outer surface of the body 2 is fixedly installed with a conveying pipe 6 with a valve, and the conveying pipe 6 is fixedly connected to the treatment box 3.

[0026] The exhaust fan 4 uses the centrifugal force generated by the rotation of the impeller to throw out the gas, forming a low-pressure zone. The exhaust gas and dust generated during the operation of the internal mixer are then drawn into the treatment box 3 through the conveying pipe 6 for treatment.

[0027] A fixed pipe 9 is fixedly installed at the outlet of the exhaust fan 4, and a three-way ball valve 8 is fixedly installed at the end of the fixed pipe 9 away from the exhaust fan 4. This three-way ball valve 8 is a T-type three-way ball valve 8, with one end being the inlet and the other end being divided into two outlets. The fixed pipe 9 is fixedly connected to the inlet of the three-way ball valve 8.

[0028] One outlet of the three-way ball valve 8 is fixedly installed with a return pipe 7 equipped with a valve, and the other outlet of the three-way ball valve 8 is fixedly installed with a transmission pipe 1003 equipped with a valve. The return pipe 7 is fixedly connected to the body 2. The three-way ball valve 8 changes the position of the through hole by rotating the ball to realize the distribution of the medium. In the initial state of the ball, the exhaust gas flows from the fixed pipe 9 to the return pipe 7. After rotation, the exhaust gas can flow from the fixed pipe 9 to the transmission pipe 1003.

[0029] The exhaust fan 4 uses the centrifugal force generated by the rotation of the impeller to throw out the gas, forming a low-pressure zone that draws in the dust and exhaust gas inside the machine body 2. The exhaust gas and dust will then enter the treatment box 3 through the conveying pipe 6 to filter the dust mixed in the exhaust gas. The filtered exhaust gas will then enter the return pipe 7 through the connecting pipe 5 and the fixed pipe 9, and then re-enter the machine body 2 through the return pipe 7, thus circulating and filtering the exhaust gas and dust to effectively filter the dust mixed in the exhaust gas.

[0030] The catalytic burner 10 is fixedly installed on the right side of the outer top surface of the workbench 1. The catalytic burner 10 uses a catalyst to reduce the activation energy required for the complete oxidation of organic matter, thereby efficiently decomposing pollutants at a lower temperature.

[0031] An air inlet 1002 is fixedly installed on one side of the outer surface of the catalytic burner 10, and an air outlet 1001 is fixedly installed on the other side of the outer surface of the catalytic burner 10. The end of the transmission pipe 1003 away from the three-way ball valve 8 is fixedly connected to the air inlet 1002. The ball of the three-way ball valve 8 is rotated to change the position of the through hole, so that the exhaust gas after circulation filtration can enter the transmission pipe 1003 and enter the interior of the catalytic burner 10 along the transmission pipe 1003. The catalyst placed in the catalytic burner 10 can activate the exhaust gas, and the electric heating component inside the catalytic burner 10 can heat the exhaust gas to decompose the pollutants in the exhaust gas. The decomposed medium will be discharged through the air outlet 1001.

[0032] A sealing plate 301 is fixedly installed on one side of the outer surface of the treatment box 3 at the opening by bolts. The sealing plate 301 can be disassembled by rotating the bolts. The interior of the treatment box 3 has four slots 302, which are arranged at equal intervals. Each of the four slots 302 has a mounting frame 303 inserted inside. The upper and lower sides of the outer surface of the four mounting frames 303 are hollow.

[0033] Two of the four mounting frames 303, located at the top, have filter plates 305 pasted inside. The other two mounting frames 303, located at the bottom, have activated carbon plates 304 fixed inside with bolts. The activated carbon plates 304 are made of activated carbon. Two filter plates 305, made of metal mesh, are positioned above the two activated carbon plates 304. When dust-laden exhaust gas passes through the filter plates 305, the dust particles, being larger than the filter holes, are trapped, achieving dust filtration. The exhaust gas then passes through the filter holes of the filter plates 305 and comes into contact with the activated carbon plates 304 located below them. The porous structure of the activated carbon plates 304 physically adsorbs pollutants, thus performing preliminary treatment of the exhaust gas.

[0034] The outer top surface of the machine body 2 is provided with a feed port 205, which can feed the polymer material to be processed into the machine body 2 through the feed head.

[0035] A support frame 202 is fixedly installed on the rear side of the outer surface of the machine body 2, and an electric push rod 203 is fixedly installed on the top surface of the support frame 202. The electric push rod 203 is located directly above the feed inlet 205. A baffle 204 is fixedly installed at the output end of the electric push rod 203, and the baffle 204 extends into the inside of the feed inlet 205. The electric push rod 203 is provided with the power required for operation by an external power source, and the electric push rod 203 can push the baffle 204 to rise and fall. When the baffle 204 descends into the inside of the feed inlet 205, it can block the feed inlet 205.

[0036] The outer surface of the machine body 2 has a discharge port 2021 on the front side, and a sealing door 201 is fixedly connected to the outer surface of the machine body 2 on one side of the discharge port 2021 by bolts. The sealing door 201 can block the discharge port 2021. With the baffle 204 blocking the inlet 205, the inside of the machine body 2 can become a sealed environment. The sealing door 201 can be easily disassembled and assembled by rotating the thread.

[0037] A protective box 206 is fixedly installed on the left side of the outer surface of the body 2. Two gears 208 are rotatably connected inside the protective box 206 and the two gears 208 are meshed. The protective box 206 can protect the two meshing gears 208, thereby preventing external factors from affecting the normal rotation of the two gears 208.

[0038] A motor 207 is fixedly installed on one side of the outer surface of the protective box 206. The motor 207 is installed on the outside of the protective box 206 by bolts, and the output end of the motor 207 extends into the inside of the protective box 206. The output end of the motor 207 is fixedly connected to one of the gears 208. The motor 207 is powered by an external power source, and the motor 207 can drive one of the gears 208 to rotate, thereby causing the two gears 208 to rotate in opposite directions.

[0039] The machine body 2 has two irregularly shaped rotors 209 rotatably connected inside. The two rotors 209 are meshing rotors 209, and two gears 208 are fixedly connected to the two rotors 209 through rotating shafts. When the two gears 208 rotate, they can drive the two rotors 209 to rotate, so as to mix the polymer material put into the machine body 2. The two rotating meshing rotors 209 squeeze and rub the polymer material under high temperature and high pressure through tooth meshing.

[0040] The working principle of this utility model is as follows: the electric push rod 203 drives the baffle 204 to rise, pulling the baffle 204 out of the feed port 205 of the machine body 2. Then, the operator puts the polymer material to be processed into the machine body 2 through the feed port 205. After all the polymer material is put in, the electric push rod 203 drives the baffle 204 to fall down until the baffle 204 falls into the feed port 205 to block the feed port 205. Then, the heating system of the machine body 2 heats the inside of the machine body 2. At this time, the motor 207 drives one of the gears 208 to rotate, so that the two meshing gears 208 drive the two irregularly shaped rotors 209 to rotate, so as to squeeze and rub the polymer material.

[0041] After the polymer material processing is completed, the valves of the conveying pipe 6 and the return pipe 7 are opened. The exhaust fan 4 uses the centrifugal force generated by the impeller rotation to throw out the gas, forming a low-pressure zone that draws in the exhaust gas and dust that fills the machine body 2. The exhaust gas and dust will enter the treatment box 3 through the conveying pipe 6. When the exhaust gas containing dust passes through the filter plate 305, the dust particles are intercepted because their diameter is larger than the filter holes, thus achieving the effect of dust filtration. The exhaust gas will pass through the filter holes of the filter plate 305 and come into contact with the activated carbon plate 304 located below the filter plate 305. The porous structure of the activated carbon plate 304 physically adsorbs the pollutants to perform preliminary treatment of the exhaust gas. The filtered exhaust gas will then enter the return pipe 7 through the connecting pipe 5 and the fixed pipe 9, and then re-enter the machine body 2 through the return pipe 7, thus circulating and filtering the exhaust gas and dust.

[0042] After circulating filtration for a period of time, the ball of the three-way ball valve 8 is rotated to change the position of the through hole, so that the exhaust gas can flow from the fixed pipe 9 to the transmission pipe 1003 and enter the interior of the catalytic burner 10 along the transmission pipe 1003. The catalyst placed in the catalytic burner 10 can reduce the activation energy of the exhaust gas. The electric heating component inside the catalytic burner 10 can heat the exhaust gas to decompose the pollutants in the exhaust gas. The decomposed medium will be discharged through the outlet 1001. Finally, the sealing door 201 is disassembled for unloading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
