Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, and more specifically, to a powder coating impurity screening device. Background Technology

[0002] Powder coating production is a process that uses physical and mechanical treatment to produce fine and uniform granular powder from specific chemical substances. It features environmental protection, high efficiency, and energy saving, and is widely used in building materials, home appliances, automobiles and other fields. The production process of powder coating mainly includes raw material preparation, premixing, melt extrusion, cooling and grinding, sieving and finished product packaging. Among these steps, sieving powder coating requires the use of screening devices to remove impurities.

[0003] However, existing technologies have some problems: existing powder coating impurity screening devices directly pour powder coating into the device for screening, causing some of the agglomerated raw materials to be screened out as impurities, reducing the utilization rate of raw materials and causing resource waste. Therefore, we propose a powder coating impurity screening device. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a powder coating impurity screening device.

[0005] According to a first aspect of the present invention, a powder coating impurity screening device is provided, comprising a support, a filter cylinder fixedly connected to the support, a filter plate fixedly connected inside the filter cylinder, a conical plate fixedly connected to the bottom of the filter cylinder, a scraping component disposed inside the filter cylinder, a feed pipe fixedly connected to the filter cylinder, a mixing tank fixedly connected to the feed pipe, a feeding component disposed inside the mixing tank, a feed hopper fixedly connected to the mixing tank, and a screening component disposed below the filter cylinder.

[0006] Optionally, the scraping assembly includes a conical sleeve, which is fixedly connected inside the filter cylinder. A first motor is fixedly connected to the conical sleeve, and the output end of the first motor is connected to a rotating shaft via a coupling.

[0007] Optionally, a scraper is fixedly connected to the outer wall of the rotating shaft, the scraper is in contact with the filter plate, and a brush is fixedly connected to one end of the rotating shaft, the brush being in contact with the conical plate.

[0008] Optionally, the feeding assembly includes a second motor, which is fixedly connected to the mixing tank, and the output end of the second motor is connected to a mixing shaft via a coupling.

[0009] Optionally, a crushing roller is fixedly connected to the outer wall of the stirring shaft, the crushing roller is disposed inside the stirring tank, and a screw rod is fixedly connected to one end of the stirring shaft, the screw rod being rotatably connected inside the feed pipe.

[0010] Optionally, the screening assembly includes a vibrator, a screening cylinder is fixedly connected to the vibrator, a spring is provided between the screening cylinder and the vibrator, a screen is fixedly connected inside the screening cylinder, and the screening cylinder is provided with a coarse material inlet and a fine material inlet.

[0011] According to one embodiment of this disclosure, the feeding assembly breaks up the agglomerated powder, improving the raw material utilization rate. After the second motor is started, it drives the stirring shaft to rotate, which in turn drives the crushing roller to rotate, thereby breaking up the agglomerated powder so that it can pass through the filter plate, improving the raw material utilization rate. When the second motor drives the stirring shaft to rotate, it also drives the screw rod to rotate, so that the powder coating can be conveyed from the feeding pipe to the filter cylinder at a uniform speed, avoiding a large amount of powder directly entering the filter cylinder and causing the filter plate to be blocked.

[0012] This utility model is equipped with a filter plate and a scraping assembly. The filter plate is used to perform preliminary filtration of powder coating, removing large particulate impurities, which can significantly improve screening efficiency, protect equipment and improve product quality. The first motor starts and drives the rotating shaft to rotate. After the rotating shaft rotates, it drives the scraper to rotate, further dispersing the powder coating and accelerating the filtration speed. At the same time, it can scrape the filter plate to prevent the filter plate from clogging. Meanwhile, when the first motor drives the rotating shaft to rotate, the brush plate rotates and scrapes off the powder adhering to the conical plate.

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1-5 As shown, a powder coating impurity screening device includes a support 1, which is welded from multiple sets of stainless steel pipes. The main function of the support 1 is to support the entire device and ensure its stable operation.

[0026] Furthermore, a filter cylinder 2 is fixedly connected to the support 1, a filter plate 3 is fixedly connected inside the filter cylinder 2, and a conical plate 4 is fixedly connected to the bottom of the filter cylinder 2. The filter plate 3 is used to perform preliminary filtration of the powder coating, removing large particulate impurities, which can significantly improve screening efficiency, protect equipment and improve product quality. The conical plate 4 facilitates the conveying of the filtered powder coating to the screening component 9 for further screening.

[0027] Furthermore, a scraping assembly 5 is provided inside the filter cylinder 2. The scraping assembly 5 includes a conical sleeve 51, which is fixedly connected inside the filter cylinder 2. A first motor 52 is fixedly connected to the conical sleeve 51, and the output end of the first motor 52 is connected to a rotating shaft 53 through a coupling.

[0028] Furthermore, a scraper 54 is fixedly connected to the outer wall of the rotating shaft 53, the scraper 54 is in contact with the filter plate 3, and a brush plate 55 is fixedly connected to one end of the rotating shaft 53, the brush plate 55 is in contact with the conical plate 4.

[0029] Specifically, the function of the conical sleeve 51 is to prevent the powder coating from accumulating on the first motor 52, and at the same time to disperse the powder coating for subsequent filtration. Meanwhile, the first motor 52 starts and drives the rotating shaft 53 to rotate. After the rotating shaft 53 rotates, it drives the scraper 54 to rotate, further dispersing the powder coating and accelerating the filtration speed. At the same time, it can scrape off the filter plate 3 to prevent the filter plate 3 from clogging. At the same time, when the first motor 52 drives the rotating shaft 53 to rotate, the brush plate 55 rotates to scrape off the powder adhering to the conical plate 4.

[0030] Furthermore, a feed pipe 6 is fixedly connected to the filter cylinder 2, and a mixing tank 7 is fixedly connected to the feed pipe 6. A feed assembly 8 is provided inside the mixing tank 7. The feed assembly 8 includes a second motor 81, which is fixedly connected to the mixing tank 7. The output end of the second motor 81 is connected to a mixing shaft 82 via a coupling.

[0031] Furthermore, a crushing roller 83 is fixedly connected to the outer wall of the stirring shaft 82, the crushing roller 83 is set inside the mixing tank 7, and a screw rod 84 is fixedly connected to one end of the stirring shaft 82, the screw rod 84 is rotatably connected inside the feed pipe 6.

[0032] Specifically, after the second motor 81 starts, it will drive the stirring shaft 82 to rotate. The rotation of the stirring shaft 82 will drive the crushing roller 83 to rotate, thereby breaking up the clumps of powder so that it can pass through the filter plate 3, improving the utilization rate of raw materials. When the second motor 81 drives the stirring shaft 82 to rotate, it will also drive the screw rod 84 to rotate, so that the powder coating can be conveyed at a uniform speed from the feed pipe 6 into the filter cylinder 2, avoiding a large amount of powder directly entering the filter cylinder 2 and causing the filter plate 3 to be blocked.

[0033] Furthermore, a feed hopper 10 is fixedly connected to the mixing tank 7, which is used to add raw materials to the device, and a screening component 9 is provided below the filter cylinder 2.

[0034] Furthermore, the screening component 9 includes a vibrator 91, a screening cylinder 92 fixedly connected to the vibrator 91, a spring 93 between the screening cylinder 92 and the vibrator 91, a screen 94 fixedly connected inside the screening cylinder 92, and a coarse material inlet 95 and a fine material inlet 96 provided on the screening cylinder 92.

[0035] Specifically, after the powder enters the screening cylinder 92 through the filter cylinder 2, the vibrator 91 drives the screening cylinder 92 and the screen 94 inside to vibrate at a high frequency. The powder is layered on the screen 94. Fine particles pass through the screen holes and finally flow out of the device through the fine material outlet 96, while coarse particles cannot pass through the screen 94 and finally flow out of the device through the coarse material outlet 95. The above screening process is a mature existing technology, and it is believed that those skilled in the art are already very familiar with it, so it will not be described in detail here.

[0036] The aforementioned powder coating impurity screening device breaks up agglomerated powder through the feeding assembly 8, thereby improving the raw material utilization rate. After the second motor 81 is started, it drives the stirring shaft 82 to rotate. The rotation of the stirring shaft 82 drives the crushing roller 83 to rotate, thereby breaking up the agglomerated powder and allowing it to pass through the filter plate 3, thus improving the raw material utilization rate. When the second motor 81 drives the stirring shaft 82 to rotate, it also drives the screw rod 84 to rotate, so that the powder coating can be uniformly transported from the feeding pipe 6 into the filter cylinder 2, avoiding a large amount of powder directly entering the filter cylinder 2 and causing the filter plate 3 to be blocked.

[0037] This utility model is equipped with a filter plate 3 and a scraping component 5. The filter plate 3 is used to perform preliminary filtration of powder coating, removing large particulate impurities, which can significantly improve screening efficiency, protect equipment and improve product quality. The first motor 52 starts and drives the rotating shaft 53 to rotate. After the rotating shaft 53 rotates, it drives the scraper 54 to rotate, further dispersing the powder coating and accelerating the filtration speed. At the same time, it can scrape the filter plate 3 to prevent the filter plate 3 from clogging. Meanwhile, when the first motor 52 drives the rotating shaft 53 to rotate, the brush plate 55 rotates to scrape off the powder adhering to the conical plate 4.

[0038] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
