Description

Technical Field

[0001] The invention relates to the field of dust treatment, and in particular to an anti-blocking device for a plastic powder exhaust pipe. Background Art

[0002] In industrial production processes such as plastic product processing and powder spraying, due to the special physical properties of plastic powder such as fine particle size, strong electrostatic adsorption and low melting temperature, traditional gas-solid separation devices are prone to scaling of the filter material surface and powder compaction on the inner wall of the pipeline during long-term operation. The air flow processing system containing plastic powder generally has the technical problem of pipeline blockage.

[0003] A Chinese patent application with authorization publication number CN212701037U discloses a pulsed back-flushing filter cartridge dust removal device, comprising a dust collection barrel and a top cover. A rotating motor is fixedly connected to the bottom inner wall of the dust collection barrel, and one end of the output shaft of the rotating motor is fixedly connected to an electric push rod. One end of the piston rod of the electric push rod is fixedly connected to a support plate. Both ends of the top outer wall of the support plate are fixedly connected to an L-shaped support plate, and one side outer wall of the L-shaped support plate is fixedly connected to a connecting block. One side outer wall of the connecting block is fixedly connected to a brush plate, and one end of the outer wall of the brush plate is fixedly connected to a brush. When removing dust from the filter cartridge, the device uses the rotating motor to drive the support plate to rotate, thereby driving the L-shaped support plate, the brush plate, and the brush to rotate. The brush plate is used to clean dust adhering to the inner wall of the dust collection barrel, and the brush is used to clean the bottom of the top cover and the filter screen, causing dust to fall into the bottom of the dust collection barrel.

[0004] Due to the special physical properties of plastic powder, such as strong electrostatic adsorption and low melting temperature, the brush of this device or a similar device is in constant contact with the rotating filter cartridge during use. During long-term operation, the plastic powder adheres firmly to the filter cartridge and the brush surface due to its strong electrostatic adsorption force. This not only seriously affects the filtration efficiency of the filter cartridge and causes a significant increase in the operating resistance of the equipment, but also causes local temperature rise due to heat accumulation. Once it approaches the melting temperature of the plastic powder, there is a risk of melting and agglomeration. On the other hand, frequent friction between the brush and the filter cartridge will not only accelerate the wear of the brush and reduce its cleaning effect, but may also generate static electricity due to friction, further aggravating the adsorption of plastic powder and even causing static sparks, posing a serious threat to safe production. In the long run, it will not only reduce the overall operating efficiency of the equipment and significantly increase maintenance costs, but may also cause equipment failures, which will have a significant impact on the continuity and safety of production.

At the same time, the evaporation of the droplets absorbs heat, preventing the local temperature from being too high, reducing the accumulation of dust due to electrostatic adsorption and the risk of melting and agglomeration due to heat, and improving production safety, stability and efficiency.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] Example 1, as Figure 1-Figure 3 As shown, a plastic powder exhaust pipe anti-clogging device includes a cylinder 1 and two exhaust pipes 2. A pipe body 2 5 is installed through the middle of the top of the cylinder 1, and a pipe body 1 3 is installed through the upper side of the outer surface of the cylinder 1. The two exhaust pipes 2 are fixedly connected to the pipe body 1 3 and the pipe body 2 5 respectively through flanges. A connecting seat 6 is fixedly installed in the middle of the inner cavity of the cylinder 1, and a storage member 7 is fixedly installed at the bottom end of the connecting seat 6. A liquid supply pipe 4 is installed through the bottom end of the storage member 7. The bottom end of the pipe body 2 5 passes through the connecting seat 6 and is connected to the inner cavity of the storage member 7. A rotating mechanism 9 is provided in the storage member 7. An atomizing mechanism 8 is provided on the connecting seat 6 and located outside the pipe body 2 5. The inner cavity of the second tube body 5 is tapered and wide at the top and narrow at the bottom. The upper side of the inner cavity of the storage element 7 is tapered and wide at the top and narrow at the bottom. The lower side of the inner cavity of the storage element 7 is disc-shaped and wide at the middle and narrow at the top and bottom. The end surface of the second tube body 5 passes through the connecting seat 6 and extends to below the highest water level line of the inner cavity of the storage element 7. During the implementation of this embodiment, the two exhaust pipes 2 are fixedly connected to the second pipe body 5 and the first pipe body 3 respectively through flanges. The exhaust pipe 2 connected to the second pipe body 5 is the air inlet pipe, and the exhaust pipe connected to the first pipe body 3 is the exhaust outlet pipe. When in use, water is injected into the storage unit 7 through the liquid supply pipe 4. The highest water level in the storage unit 7 should be above the outlet on the lower surface of the second pipe body 5. When the plastic dust is blown into the second pipe body 5 through the exhaust pipe 2 connected to the second pipe body 5, the wind blows the upper half of the rotating mechanism 9, so that the rotating mechanism 9 rotates to generate a cyclone. The inertia of the centrifugal force generated by the cyclone is used to throw the plastic dust entering the second pipe body 5 toward the inner surface of the second pipe body 5. In this way, the synergistic effect of the atomized water mist sprayed by the atomizing mechanism 8 is used to wet the plastic dust to induce liquid bridge condensation. When the liquid droplets come into contact with the plastic dust particles, the dust particles will attract and adhere to each other, and gradually agglomerate into a larger sediment. In this process, the particle size of the dust particles increases significantly, and the mass also increases accordingly, making it have a stronger sedimentation tendency. The sediment with an increased volume flows into the storage member 7 and is more easily mixed with the water in the storage member 7. During the rotation of the upper half of the rotating mechanism 9, the lower half thereof stirs the water in the storage part 7. The centrifugal force generated by the stirring of the rotating mechanism 9 causes the water in the storage part 7 to form a vortex. The center of the vortex is empty, causing the lower surface of the tube body 2 5 to leak out of the water in the storage part 7. In this way, the sediment flowing out of the tube body 2 5 is separated from the air flow. The sediment flows into the water in the storage part 7 and dissolves in the water. The air flow is blown onto the water in the storage part 7 and encounters resistance, then turns upward and flows through the tube body 1 3 into the exhaust pipe 2 connected to the tube body 1 3 before being discharged outward. The atomization effect produced by the atomization mechanism 8 can effectively reduce the probability of frictional electrification of plastic dust and accelerate the dissipation of static electricity. The atomized droplets can transfer the charge when in contact with the charged dust. At the same time, the droplets evaporate and absorb heat, preventing the local temperature from being too high, and reducing the accumulation of dust due to electrostatic adsorption and the risk of melting and agglomeration due to heat.

[0021] Example 2: This example describes the specific operation process and coordination effect of the atomizing mechanism 8 and the rotating mechanism 9 based on Example 1. Specific examples Figure 4-Figure 6 As shown, the rotating mechanism 9 includes a supporting seat 92 and a plurality of air flow holes 91. The plurality of air flow holes 91 are arranged in a circular array on the side of the top of the connecting seat 6 away from the middle. The bottom end of the supporting seat 92 is fixedly mounted with a plurality of support rods 921 fixedly connected to the bottom end of the inner cavity of the storage element 7. A rotating shaft 93 is rotatably mounted in the middle of the top end of the supporting seat 92. A connecting ring 94 is coaxially fixedly connected to the lower side of the outer surface of the rotating shaft 93. A plurality of stirring plates 941 are fixedly installed in an annular array on the outer surface of the connecting ring 94. A vortex vane 95 is coaxially fixedly connected to the upper side of the outer surface of the rotating shaft 93. When the wind sweeps the plastic powder into the tube body 2 5, the wind blows the vortex vanes 95 to rotate. The centrifugal force generated by the rotation of the vortex vanes 95 throws the plastic dust in the tube body 2 5 to the inner surface of the tube body 2 5. As the atomizing mechanism 8 works, the water in the storage element 7 is atomized and sprayed into the tube body 2 5 to mix with the plastic powder. During the rotation of the vortex blades 95, the rotating shaft 93 drives the multiple stirring plates 941 installed in a circular array on the outer surface of the connecting ring 94 to rotate. The multiple connecting rings 94 rotate in the storage part 7, causing the water stored in the storage part 7 to form a vortex. At this time, the centrifugal force generated by the rotation of the water in the storage part 7 diverges along the upper outer surface of the inner cavity of the storage part 7 toward a point away from the center, thereby preventing the water in the storage part 7 from submerging the water outlet opening of the tube body 2 5. In this way, the sediment flowing out of the tube body 2 5 is separated from the airflow. The sediment flows into the water in the storage part 7 and dissolves in the water. The airflow blows onto the water in the storage part 7, encounters resistance, turns upward, and floats out through the multiple airflow holes 91 and is guided to the outside world by the tube body 1 3. As the multiple 841 rotate, when the sediment falls into the storage part 7, it flows with the vortex, preventing the sediment from floating on the water surface in the storage part 7 to prevent the sediment from mixing with the water later.

[0022] Specifically, the atomizing mechanism 8 includes an upper liquid ring seat 81 and a water pump 82. The water pump 82 is fixedly mounted on the side of the top of the connecting seat 6 away from the middle. The output end of the water pump 82 is fixedly connected to an upper water pipe 2 84. The input end of the water pump 82 is fixedly connected to an upper water pipe 1 83. The end of the upper water pipe 1 83 away from the water pump 82 passes through the outer surface of the storage member 7 and extends to the lower side of the inner cavity of the storage member 7. The upper liquid ring seat 81 is sleeved on the outer surface of the tube body 5. A plurality of support rods 811 are installed in a rectangular array at the bottom end of the upper liquid ring seat 81. The ends of the plurality of support rods 811 away from the upper liquid ring seat 81 are fixedly connected to the top of the connecting seat 6. The end of the upper water pipe 84 away from the water pump 82 penetrates the inner cavity of the upper liquid ring seat 81. A plurality of atomizing nozzles 85 are installed in a circular array on the side of the upper liquid ring seat 81 close to the second pipe body 5. The output ends of the plurality of atomizing nozzles 85 respectively penetrate the inner cavity of the second pipe body 5. Start the water pump 82, which transports the water in the storage unit 7 to the inner cavity of the upper liquid ring seat 81 through the upper water pipe 1 83 and the upper water pipe 2 84, and atomizes the water entering the upper liquid ring seat 81 through multiple atomizing nozzles 85 in the upper liquid ring seat 81 and sprays it into the pipe body 2 5 to mix with the plastic powder.

[0023] It should be noted that the specific installation method of the water pump 82 used in the present invention, the circuit connection method and the control method are all conventional designs and will not be elaborated in detail in the present invention.
