Description

Technical Field

[0001] The invention relates to the technical field of cyclone separators, in particular to a cyclone separator for collecting powder coatings. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigments, fillers and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. Powder coatings are divided into two categories: thermoplastic and thermosetting. The coating film of thermoplastic powder coating has poor appearance and poor adhesion to metal. Thermosetting powder coating uses thermosetting synthetic resin as film-forming material. In the production of powder coating, a cyclone separator is required to separate impurities in the coating.

[0003] A cyclone separator is a device that separates gas-solid systems or liquid-solid systems. It relies on the tangential airflow to form a spiral airflow inside the separator. The rotating motion of the airflow causes the larger inertial centrifugal force to throw the powder coating particles to the outer wall to separate them. During the operation of the existing cyclone separator, powder is easily accumulated on the inner wall of the separator. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A cyclone separator for collecting powder coatings, comprising a shell and a bracket fixedly mounted on the outside of the shell, the shell being located inside the bracket, a feed pipe being fixedly connected to the outside of the shell, the feed pipe being located above the bracket, and a motor being fixedly connected to the top of the shell; A connecting assembly is fixedly connected to the bottom of the shell, and a collecting cylinder is fixedly connected to the bottom of the connecting assembly; The discharging assembly is fixedly mounted inside the housing, and the output end of the motor is fixedly connected to the discharging assembly; The shell includes a cylinder, the outer side of the cylinder is fixedly connected to the bracket, the outer side of the cylinder is fixedly connected to the feed pipe, the feed pipe is connected to the cylinder, and the bottom of the cylinder is fixedly connected to a conical cylinder. The inner wall of the conical cylinder is provided with a spiral plate, which allows the airflow with powder coating to enter the interior of the cylinder tangentially through the feed pipe. Under the guidance of the spiral plate, the airflow flows along the spiral plate. Due to the action of centrifugal force, the dust particles with higher density in the airflow are thrown to the inner wall of the conical cylinder, and then the dust slides down along the inner wall of the conical cylinder, and the purified gas is discharged along the discharge assembly. The presence of multiple spiral plates extends the movement path of the airflow and dust in the separator, increases the chance of dust colliding with the inner wall, thereby improving the separation efficiency. At the same time, multiple spiral plates can make the airflow evenly distributed in the conical cylinder, avoiding the airflow being concentrated in a certain area, thereby ensuring that the entire separator cross-section can effectively perform gas-solid separation, improving the processing capacity of the separator and the stability of the separation effect. There are multiple spiral plates evenly distributed inside the conical cylinder, and the inner wall of the conical cylinder is provided with spiral grooves. When the airflow makes a spiral motion in the conical cylinder, the dust particles thrown to the inner wall of the conical cylinder by centrifugal force will fall into the spiral grooves. Due to the spiral shape of the guide grooves, the dust particles will move downward along the groove spiral under the combined action of gravity and airflow, and finally be guided to the ash discharge port for discharge. By setting the spiral grooves, the spiral guide grooves provide a clear flow path for the dust particles, so that the dust can move more smoothly to the ash discharge port, reducing the accumulation and back mixing of dust on the inner wall of the conical cylinder, and improving the efficiency and stability of ash discharge. A circular hole is provided in the middle of the top of the cylinder, and the discharge assembly is located inside the circular hole, and the discharge assembly passes through the cylinder through the circular hole and extends to the inside of the cylinder. The top of the cylinder is fixedly connected to a support plate, and the top of the support plate is fixedly connected to the motor.

[0005] Preferably, the discharging assembly includes a middle cylinder, which is fixedly connected to the cylinder body, the middle cylinder is located inside the circular hole, the output end of the motor is fixedly connected to the rotating shaft, the rotating shaft is located in the middle of the middle cylinder, the bottom of the middle cylinder is fixedly connected to a fixed pipe, the fixed pipe is located inside the conical cylinder, and the outer side of the rotating shaft is fixedly connected to a connecting rod. After the airflow enters the interior of the cylinder body from the feed pipe, it forms a spiral downward rotating airflow under the guidance of the spiral plate. The outer vortex gas will continuously squeeze the gas at the bottom of the separator during the downward flow, causing the gas pressure at the bottom to increase, while the gas pressure at the middle cylinder is relatively low, thus forming a spiral flow in the conical cylinder. The pressure difference from the bottom to the top. Under the action of this pressure difference, part of the gas begins to flow upward from the center of the conical cylinder, forming an internal vortex, so that the airflow is discharged. The airflow passes through multiple staggered fixed rings and fixed plates, and the direction of the airflow will change, resulting in a complex flow pattern. The dust in the airflow will form local vortices and circulations between the fixed rings and the fixed plates, and the dust content in the discharged airflow will be reduced, thereby achieving gas purification and improving dust removal efficiency. The connecting rod is fixedly connected to the middle cylinder, and the outer side of the rotating shaft is fixedly connected with a fixed plate. There are multiple fixed plates, and the inner wall of the middle cylinder is fixedly connected with a fixed plate. The filter plate is located at one end of the middle tube close to the fixed tube, and the top of the filter plate is fixedly connected with a reset spring, and the end of the reset spring away from the filter plate is fixedly connected to the fixed ring. The fixed tube is conical in design, and a slide groove is provided on the inner wall of the fixed tube. A guide block is provided in the middle of the fixed tube. The guide block is magnetic, and the magnetism between the guide block and the rotating plate is the same. Under the action of the pressure difference, the airflow enters the interior of the middle tube through the gap between the guide block and the fixed tube, and the airflow passes through the filter plate to perform preliminary filtration on the discharged airflow. At the same time, the external power supply of the motor works, and the motor drives the rotating rod to rotate, and the rotating rod drives the rotating plate to rotate, so that the rotating plate is close to the guide block. Under the mutual repulsive force between the guide block and the rotating plate, the guide block moves upward inside the chute through the slider, so that the ball knocks the filter plate to prevent the filter plate from being blocked. The guide block is conical in shape, and a slider is fixedly connected to the outside of the guide block. There are multiple sliders, and the multiple sliders are evenly distributed with the guide block as the center. The slider is located inside the chute, and the guide block is slidably connected to the chute through the slider. The top of the guide block is fixedly connected with a ball, and the ball is located in the gap between the guide block and the filter plate.

[0006] Preferably, the connecting assembly includes an intermediate cylinder, the top of the intermediate cylinder is fixedly connected to the bottom of the conical cylinder, the bottom of the intermediate cylinder is fixedly connected to a cylinder, the inner wall of the cylinder is provided with a threaded groove, the cylinder is threadedly connected to the top outer side of the collecting cylinder through the threaded groove, the top of the cylinder is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating rod, the motor is connected to an external power supply to work, the motor drives the rotating rod to rotate, the rotating rod drives the rotating plate to rotate, and then the rotating plate drives the dust into the interior of the collecting cylinder, and the rotation of the rotating plate can more effectively guide the dust from the separator body to the collecting cylinder, prevent dust from accumulating on the inner wall of the intermediate cylinder, keep the channel unobstructed, thereby improving the dust collection efficiency of the entire cyclone separator, and at the same time avoid excessive wear and corrosion of the separator cylinder wall and other components due to dust accumulation, thereby extending the overall service life of the cyclone separator, the rotating rod is rotatably connected to the intermediate cylinder, and the rotating rod The cam is fixedly provided with a toothed plate on the outside of the cam and is magnetic. The cam is located inside the cam and has multiple cams, which are evenly distributed around the cam. A groove is provided on the inner wall of the cam and there are two grooves, which are symmetrically arranged around the cam. A compression spring is fixedly connected to the inner wall of the groove. The motor is connected to an external power supply to operate. The motor drives the cam to rotate, and the cam drives the cam to rotate, so that the cam contacts the protrusion on the side wall and is squeezed. The compression spring is compressed, and the protrusion moves on the inner wall of the groove in the direction away from the rotating plate, so that the rotating plate rotates smoothly. When the cam stops rotating, the protrusion is reset under the elastic force of the compression spring. At this time, the rotating plate stops rotating under the limit of the protrusions on both sides. The inner wall of the groove is slidably connected with a protrusion, and the protrusion is fixedly connected to one end of the compression spring away from the groove.

[0007] The present invention provides a cyclone separator for collecting powder coatings. It has the following beneficial effects: 1. The cyclone separator for collecting powder coatings extends the movement path of airflow and dust in the separator by setting up multiple spiral plates, increases the chance of dust colliding with the inner wall, and thus improves the separation efficiency.

DETAILED DESCRIPTION

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The presence of multiple spiral plates 22 prolongs the movement path of the airflow and dust in the separator, increases the chance of dust colliding with the inner wall, and thus improves the separation efficiency. At the same time, multiple spiral plates 22 can make the airflow evenly distributed in the conical cylinder 21, avoiding the airflow from concentrating in a certain area, thereby ensuring that the entire separator cross section can effectively perform gas-solid separation, improving the separator's processing capacity and the stability of the separation effect. The number of spiral plates 22 is large. A plurality of spiral plates 22 are evenly distributed inside the conical cylinder 21. A spiral groove 23 is opened on the inner wall of the conical cylinder 21. When the airflow makes a spiral motion in the conical cylinder 21, the dust particles thrown to the inner wall of the conical cylinder by the centrifugal force will fall into the spiral groove 23. Due to the spiral shape of the guide groove, the dust particles will move downward along the groove spiral under the combined action of gravity and airflow, and will eventually be guided to the ash discharge port for discharge. By setting the spiral groove 23, the spiral guide groove provides a clear flow path for the dust particles, so that the dust can move more smoothly to the ash discharge port , reducing the accumulation and back-mixing of dust on the inner wall of the conical cylinder, and improving the efficiency and stability of ash discharge. A circular hole 24 is opened in the middle of the top of the cylinder 27, and the discharge component 7 is located inside the circular hole 24. The discharge component 7 passes through the cylinder 27 through the circular hole 24 and extends to the inside of the cylinder 27. The top of the cylinder 27 is fixedly connected with a pillar 25. There are multiple pillars 25, and the multiple pillars 25 are evenly distributed with the discharge component 7 as the center. The top of the pillar 25 is fixedly connected with a support plate 26, and the top of the support plate 26 is fixedly connected to the motor 5.

[0015] The second embodiment, based on the first embodiment, see Figures 5 to 7As shown, the discharge assembly 7 includes a middle cylinder 72, the outer side of the middle cylinder 72 is fixedly connected to the inner wall of the spiral plate 22, the motor 5 is connected to an external power supply to work, the motor 5 drives the middle cylinder 72 to rotate through the rotating shaft 71, and the middle cylinder 72 drives the spiral plate 22 to rotate. The rotation of the spiral plate 22 can produce a certain pushing effect on the dust that has been separated on the inner wall of the conical cylinder 21, helping the dust to move to the bottom faster along the wall of the device, reducing the accumulation of dust on the inner wall of the conical cylinder 21, and preventing the dust from being entrained by the air flow again due to long-term residence, thereby ensuring the smoothness of ash discharge and improving the operating stability of the separator. The middle cylinder 72 is fixedly connected to the cylinder body 27, and the middle cylinder 72 is located inside the circular hole 24. The output end of the motor 5 is fixedly connected to the rotating shaft 71, and the rotating shaft 71 is located in the middle cylinder 7 2, the bottom of the middle cylinder 72 is fixedly connected to a fixed pipe 73, which is located inside the conical cylinder 21. The outer side of the rotating shaft 71 is fixedly connected to a connecting rod 74. After the airflow enters the interior of the cylinder 27 tangentially from the feed pipe 4, it forms a spiral downward rotating airflow under the guidance of the spiral plate 22. The outer vortex gas will continuously squeeze the gas at the bottom of the separator during the downward flow, causing the bottom gas pressure to increase, while the gas pressure at the middle cylinder 72 is relatively low. In this way, a pressure difference from the bottom to the top is formed in the conical cylinder 21. Under the action of this pressure difference, part of the gas begins to flow upward from the center of the conical cylinder 21, forming an inner vortex, so that the airflow is discharged. The airflow passes through multiple staggered fixing rings 76 and fixed plates The dust in the airflow will form local vortex and circulation between the fixing ring 76 and the fixing plate 75, and the dust content in the exhaust airflow will be reduced, thereby achieving gas purification and improving the dust removal efficiency. The connecting rod 74 is fixedly connected to the middle cylinder 72, and the outer side of the rotating shaft 71 is fixedly connected to the fixing plate 75. There are multiple fixing plates 75. The inner wall of the middle cylinder 72 is fixedly connected to the fixing ring 76. There are multiple fixing rings 76. Multiple fixing rings 76 and fixing plates 75 are staggered.

At the same time, the motor 63 is connected to the external power supply to work, and the motor 63 drives the rotating rod 64 to rotate. The rotating rod 64 drives the rotating plate 65 to rotate, so that the rotating plate 65 is close to the guide block 710. Under the mutual repulsion between the guide block 710 and the rotating plate 65,The guide block 710 moves upward inside the chute 79 via the slider 711, causing the ball 712 to strike the filter plate 78 to prevent the filter plate 78 from being blocked. The guide block 710 is conical in shape, and a slider 711 is fixedly connected to the outside of the guide block 710. There are multiple sliders 711, and the multiple sliders 711 are evenly distributed around the guide block 710. The slider 711 is located inside the chute 79, and the guide block 710 is slidably connected to the chute 79 via the slider 711. The top of the guide block 710 is fixedly connected to the ball 712, and the ball 712 is located in the gap between the guide block 710 and the filter plate 78.

[0016] The third embodiment, based on the first and second embodiments, see Figures 8 and 9 As shown, the connecting assembly 6 includes an intermediate cylinder 61, the top of the intermediate cylinder 61 is fixedly connected to the bottom of the conical cylinder 21, the bottom of the intermediate cylinder 61 is fixedly connected to a cylinder 62, the inner wall of the cylinder 62 is provided with a threaded groove 66, the cylinder 62 is threadedly connected to the outer side of the top of the collecting cylinder 3 through the threaded groove 66, the top of the cylinder 62 is fixedly connected to a motor 63, the output end of the motor 63 is fixedly connected to a rotating rod 64, the motor 63 is connected to an external power supply to work, the motor 63 drives the rotating rod 64 to rotate, the rotating rod 64 drives the rotating plate 65 to rotate, and then The rotating plate 65 drives the dust into the interior of the collecting cylinder 3. The rotation of the rotating plate 65 can more effectively guide the dust from the separator body to the collecting cylinder 3, prevent the dust from accumulating on the inner wall of the intermediate cylinder 61, keep the channel unobstructed, thereby improving the dust collection efficiency of the entire cyclone separator, and at the same time avoid excessive wear and corrosion of the separator cylinder wall and other components due to dust accumulation, thereby extending the service life of the cyclone separator as a whole. The rotating rod 64 is rotatably connected to the intermediate cylinder 61. The rotating rod 64 is vertically arranged to the intermediate cylinder 61, and the rotating rod 64 passes through the middle tube 61, and the outer side of the rotating rod 64 is fixedly connected with a rotating plate 65, which is magnetic and is located inside the middle tube 61. There are multiple rotating plates 65, and the multiple rotating plates 65 are evenly distributed with the rotating rod 64 as the center.

The inner wall of the groove 67 is fixedly connected with a compression spring 68. The motor 63 is connected to an external power supply to work, and the motor 63 drives the rotating rod 64 to rotate. 4 drives the rotating plate 65 to rotate, so that the rotating plate 65 contacts and squeezes the protrusion 69 on the side wall, thereby compressing the compression spring 68. The protrusion 69 moves along the inner wall of the groove 67 in a direction away from the rotating plate 65, so that the rotating plate 65 rotates smoothly. When the rotating rod 64 stops rotating, the protrusion 69 returns to its original position under the elastic force of the compression spring 68. At this time, the rotating plate 65 stops rotating under the limit of the protrusions 69 on both sides. The inner wall of the groove 67 is slidably connected to the protrusion 69, and the protrusion 69 is fixedly connected to the end of the compression spring 68 away from the groove 67.

[0017] During use, after the airflow enters the interior of the cylinder 27 tangentially from the feed pipe 4, it forms a spiral downward rotating airflow under the guidance of the spiral plate 22. During the downward flow, the outer vortex gas will continuously squeeze the gas at the bottom of the separator, causing the bottom gas pressure to increase, while the gas pressure at the middle cylinder 72 is relatively low. In this way, a pressure difference from the bottom to the top is formed in the conical cylinder 21. Under the action of this pressure difference, part of the gas begins to flow upward from the center of the conical cylinder 21, forming an inner vortex, thereby discharging the airflow.

[0018] At the same time, the air flow flows along the spiral plate 22. Due to the action of centrifugal force, the dust particles with higher density in the air flow are thrown to the inner wall of the conical cylinder 21, and then the dust slides down along the inner wall of the conical cylinder 21. The motor 63 is connected to an external power supply and works. The motor 63 drives the rotating rod 64 to rotate, and the rotating rod 64 drives the rotating plate 65 to rotate.
