Description

Technical Field

[0001] The utility model relates to the technical field of powder coatings, in particular to a drying device for powder coatings. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.

[0003] A Chinese patent discloses a drying device for powder coating production, with the authorization announcement number CN219776212U. The water vapor generated during drying in this patented technology rises and enters the air outlet box, and then leaves the drum from the through holes of the filter plate. A small amount of water vapor is adsorbed on the bottom of the filter plate and condenses into water droplets. At this time, the second motor is started, and the threaded rod rotates, driving the slider, the slide plate and the brush plate to move back and forth along the slide groove. The brush plate contacts the bottom of the filter plate, scrapes off the water droplets, and makes them fall into the collection box, thereby minimizing the probability of water droplets falling into the powder coating and improving the drying efficiency.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing drying device transports the powder coating into a tank body, heats the tank body to evaporate the water in the powder coating, and then when taking out the dry powder coating, the powder inside the tank body needs to be manually taken out. Since there is a lot of powder, the taking out process takes a lot of time, which affects the subsequent drying efficiency of the powder. Utility Model Content

[0005] The technical problem to be solved by the utility model is that in the prior art, after the water in the powder coating is evaporated, when taking out the dry powder coating, the powder in the tank needs to be taken out manually. Since there is a lot of powder, the taking out process takes a lot of time. For this reason, we propose a drying device for powder coating.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a drying device for powder coating, comprising a bottom bracket, the top of the bottom bracket is rotatably connected to a tank body, a control cabinet is installed on one side of the bottom bracket, a DC motor is installed at one end of the bottom bracket, a heating device is installed inside the bottom bracket, an auger is fixedly connected to the inside of the tank body, and a feeding pipe is rotatably connected to one end of the tank body.

[0007] Preferably, both sides of the bottom bracket are fixedly connected with heat insulation plates.

[0008] Preferably, the top of the bottom bracket is rotatably connected to four extension plates via a rotating shaft, and the inside of the bottom bracket and the top of the extension plate are rotatably connected to a pulley.

[0009] Preferably, a round rod is fixedly connected to one side of the bottom bracket, a connecting plate is rotatably connected to the surface of the round rod, a threaded rod is internally threadedly connected to the extension plate, a sliding groove is provided on one side of the connecting plate, and the surface of the threaded rod is slidably connected to the inside of the sliding groove.

[0010] Preferably, two limiting grooves are provided on the surface of the tank body, and the pulley is slidably connected to the inside of the limiting grooves.

[0011] Preferably, the height of the pulley is higher than the height of the central axis of the tank body.

[0012] Preferably, a water pipe is installed inside the feeding pipe.

[0013] Preferably, the diameter of the water pipe is smaller than the inner diameter of the feeding pipe, and the feeding pipe is parallel to the water pipe.

[0014] Technical effects and advantages of the utility model:

[0015] In the utility model, the user delivers the powder coating to be dried to the inside of the tank body through the feeding pipe, controls the DC motor to start through the control cabinet, drives the tank body to rotate counterclockwise, and at the same time the heating device heats the tank body to make the tank body evaporate the moisture of the powder coating inside. When the tank body rotates counterclockwise, the auger on the inner wall of the tank body drives the powder inside the tank body to move backward to prevent the powder from falling from the inside of the tank body. After the powder coating is dried, the DC motor is controlled by the control cabinet to rotate in the opposite direction to drive the tank body to rotate clockwise.

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a drying device for powder coating, comprising a bottom bracket 1, the top of the bottom bracket 1 is rotatably connected to a tank body 2, a control cabinet 3 is installed on one side of the bottom bracket 1, a DC motor 4 is installed on one end of the bottom bracket 1, a heating device 5 is installed inside the bottom bracket 1, an auger 6 is fixedly connected inside the tank body 2, and a feeding pipe 7 is rotatably connected to one end of the tank body 2. The user delivers the powder coating to be dried to the inside of the tank body 2 through the feeding pipe 7, and controls the DC motor 4 to start the heating device 5 through the control cabinet 3. The tank body 2 rotates counterclockwise, and the heating device 5 heats the tank body 2, so that the tank body 2 evaporates the moisture of the powder coating inside. When the tank body 2 rotates counterclockwise, the auger 6 on the inner wall of the tank body 2 drives the powder inside the tank body 2 to move backward to prevent the powder from falling from the inside of the tank body 2. After the powder coating is dried, the control cabinet 3 controls the DC motor 4 to rotate in the opposite direction to drive the tank body 2 to rotate clockwise. The auger 6 inside the tank body 2 drives the powder coating to move to the outlet of the tank body 2, which is convenient for quick unloading and improves the efficiency of subsequent drying.

[0024] Reference Figure 4 As shown, in this embodiment: both sides of the bottom bracket 1 are fixedly connected with insulation plates 8. The user turns on the heating device 5 through the control cabinet 3. When heating the tank body 2, the insulation plates 8 on both sides of the bottom bracket 1 can effectively prevent the heat generated by the heating device 5 from being lost too quickly, thereby increasing the heating speed of the tank body 2 and preventing nearby staff from being scalded.

[0025] Reference Figure 4As shown, in this embodiment: the top of the bottom bracket 1 is rotatably connected to four extension plates 9 through a rotating shaft, and the inside of the bottom bracket 1 and the top of the extension plate 9 are rotatably connected to a pulley 10. When the user controls the DC motor 4 to start through the control cabinet 3 and drives the tank body 2 to rotate, the pulley 10 rotates along with the rotation of the tank body 2, reducing the friction between the tank body 2 and the bottom bracket 1, making the rotation of the tank body 2 smoother, while reducing the wear of the tank body 2 and increasing the service life of the tank body 2.

[0026] Reference Figure 2 As shown, in the present embodiment: a round rod 12 is fixedly connected to one side of the bottom bracket 1, a connecting plate 13 is rotatably connected to the surface of the round rod 12, a threaded rod 14 is internally threadedly connected to the extension plate 9, a slide groove 15 is provided on one side of the connecting plate 13, and the surface of the threaded rod 14 is slidably connected to the inside of the slide groove 15. The user releases the limit on the connecting plate 13 by rotating the threaded rod 14, so that the extension plate 9 can be rotated, and the angles of the extension plates 9 on both sides are adjusted, so that tank bodies 2 of different specifications can be loaded into the top of the bottom bracket 1, thereby meeting different production needs.

[0027] Reference Figure 4 As shown, in this embodiment: two limit grooves 11 are provided on the surface of the tank body 2, and the surface of the pulley 10 is slidably connected with the inside of the limit groove 11. When the user controls the DC motor 4 to start through the control cabinet 3 and drives the tank body 2 to rotate, the pulley 10 rolls inside the limit groove 11 to limit the tank body 2 and prevent the tank body 2 from moving forward and backward during the rotation.

[0028] Reference Figure 4 As shown, in this embodiment: the height of the pulley 10 is higher than the height of the central axis of the tank body 2. By making the height of the pulley 10 higher than the height of the central axis of the tank body 2, the tank body 2 can be prevented from tilting upward during rotation, thereby avoiding the danger of the tank body 2 falling.

[0029] Reference Figure 5 As shown, in this embodiment: a water pipe 16 is installed inside the feed pipe 7, and the DC motor 4 is controlled by the control cabinet 3 to rotate in the opposite direction, driving the tank body 2 to rotate clockwise, and the auger 6 inside the tank body 2 drives the powder coating to move to the outlet of the tank body 2 for unloading. After the unloading is completed, when it is necessary to dry the powder coating of other colors, water is injected into the inside of the tank body 2 through the water pipe 16 to clean the inner wall of the tank body 2 to prevent the residual powder coating from affecting the subsequent other color coatings.

[0030] Reference Figure 3 and Figure 5 As shown, in this embodiment: the diameter of the water pipe 16 is smaller than the inner diameter of the feeding pipe 7, and the feeding pipe 7 is parallel to the water pipe 16. By setting the diameter of the water pipe 16 smaller than that of the feeding pipe 7, clogging of the feeding pipe 7 when conveying powder coating can be avoided.

[0031] Working principle: The user delivers the powder coating to be dried to the inside of the tank body 2 through the feeding pipe 7, and controls the DC motor 4 to start through the control cabinet 3, driving the tank body 2 to rotate counterclockwise. At the same time, the heating device 5 heats the tank body 2, so that the tank body 2 evaporates the moisture of the powder coating inside. When the tank body 2 rotates counterclockwise, the auger 6 on the inner wall of the tank body 2 drives the powder inside the tank body 2 to move backward to prevent the powder from falling from the inside of the tank body 2. After the powder coating is dried, the DC motor 4 is controlled by the control cabinet 3 to rotate in the opposite direction. The tank body 2 is driven to rotate clockwise, and the auger 6 inside the tank body 2 drives the powder coating to move toward the outlet of the tank body 2. The heating device 5 is turned on through the control cabinet 3. When the tank body 2 is heated, the heat insulation plates 8 on both sides of the bottom bracket 1 can effectively prevent the heat generated by the heating device 5 from being lost too quickly, thereby increasing the heating speed of the tank body 2 and preventing nearby staff from being scalded. The DC motor 4 is controlled to start through the control cabinet 3. When the tank body 2 is driven to rotate, the pulley 10 rotates with the rotation of the tank body 2, thereby reducing the friction between the tank body 2 and the bottom bracket 1, making the rotation of the tank body 2 smoother and reducing the wear of the tank body 2. The limit of the connecting plate 13 is released by rotating the threaded rod 14, so that the extension plate 9 can rotate. By adjusting the angles of the extension plates 9 on both sides, tanks 2 of different specifications can be loaded into the top of the bottom bracket 1. The DC motor 4 is controlled to start through the control cabinet 3. When the tank body 2 is driven to rotate, the pulley 10 rolls inside the limit groove 11 to limit the tank body 2 and prevent the tank body 2 from moving forward and backward during the rotation. By raising the height of the pulley 10 to a height higher than The height of the central axis of the tank body 2 can prevent the tank body 2 from tilting upward during rotation. The DC motor 4 is controlled by the control cabinet 3 to rotate in the opposite direction, driving the tank body 2 to rotate clockwise. The auger 6 inside the tank body 2 drives the powder coating to move to the outlet of the tank body 2 for unloading. After unloading, when it is necessary to dry powder coatings of other colors, water is injected into the interior of the tank body 2 through the water pipe 16 to clean the inner wall of the tank body 2. The diameter of the water pipe 16 is set to be smaller than the feeding pipe 7 to avoid blockage of the feeding pipe 7 when conveying powder coating.
