Description

Technical Field

[0001] This utility model belongs to the field of raw lacquer processing technology, specifically relating to a continuous raw lacquer filtration device. Background Technology

[0002] Existing raw lacquer processing technologies mainly employ static filtration or simple mechanical separation methods, such as multi-layer filter screen filtration, centrifugal separation, or sedimentation for impurity removal. These methods generally suffer from low efficiency, easy clogging, and frequent manual intervention. Traditional equipment is difficult to operate continuously, and manual cleaning of residues is still required after filtration. Furthermore, its effectiveness in separating fine impurities is limited, affecting the purity of raw lacquer and production efficiency.

[0003] Authorization announcement number "CN217490019U" discloses a continuous raw lacquer filtration device, including a frame. The device is characterized by: an inclined frame mounted on the frame; a feeding hopper at the lower end of the inclined frame and a partition at the higher end, with a discharge hole on the partition; guard rods on both sides of the inclined frame; a rotating drum rotatably mounted between the guard rods; one end of the rotating drum communicating with the feeding hopper and the other end communicating with the discharge hole on the partition; a three-pronged plate fixedly mounted on the end of the rotating drum communicating with the discharge hole; a motor driving the three-pronged plate to drive the rotating drum to rotate; a spiral lifting blade inside the rotating drum; and filter holes on the side wall of the rotating drum. This application adopts a continuous feeding and continuous filtration working mode, which can be applied to different feeding and harvesting speeds. Filtration, separation, and lacquer collection are carried out simultaneously, greatly improving production efficiency.

[0004] The above-mentioned new type can be applied to different feeding and cutting speeds, and filtration, separation and paint collection are carried out simultaneously, which greatly improves production efficiency. However, when the raw paint is continuously filtered, impurities will be blocked on the filter screen. As the impurities increase, the filter screen will become clogged, which is not conducive to the continuous filtration of raw paint by the device. It is necessary to stop the filtration work at regular intervals to clean the filter screen. Utility Model Content

[0005] The purpose of this invention is to provide a continuous raw lacquer filtration device, which aims to solve the problem in the prior art where impurities are blocked on the filter screen during continuous filtration of raw lacquer, and the increased amount of impurities will clog the filter screen, which is not conducive to continuous filtration of raw lacquer and requires periodic filtration to be stopped to clean the filter screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A continuous lacquer filtration device, comprising:

[0008] Raw lacquer filter cylinder;

[0009] The feed inlet is located at the upper end of the raw lacquer filter cylinder;

[0010] A liquid material filtration mechanism includes a material conveying screen, a rotating sleeve, a rotating rod, an auger, filter holes, a motor mounting slot, a drive motor, a rotating base plate, and a slag outlet. The material conveying screen is fixedly connected to one side of the raw lacquer filter cylinder. The rotating sleeve is located at one side of the material conveying screen. The rotating rod is rotatably connected inside the rotating sleeve. The auger is fixedly connected to the outer surface of the rotating rod. The filter holes are located on the outer surface of the auger. The motor mounting slot is fixedly connected to one side of the raw lacquer filter cylinder.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1-5 The present invention provides the following technical solution:

[0029] A continuous lacquer filtration device, comprising:

[0030] Raw lacquer filter cartridge 1;

[0031] Feed inlet 2 is located at the upper end of the raw lacquer filter cylinder 1;

[0032] The liquid material filtration mechanism includes a material conveying screen 3, a rotating sleeve 4, a rotating rod 5, an auger 6, a filter hole 7, a motor fixing slot 9, a drive motor 10, a rotating base plate 11, and a slag outlet 14. The material conveying screen 3 is fixedly connected to one side of the raw lacquer filter cylinder 1. The rotating sleeve 4 is located at one side of the material conveying screen 3. The rotating rod 5 is rotatably connected inside the rotating sleeve 4. The auger 6 is fixedly connected to the outer surface of the rotating rod 5. The filter hole 7 is located on the outer surface of the auger 6. The motor fixing slot 9 is fixedly connected to one side of the raw lacquer filter cylinder 1. The drive motor 10 is fixedly connected inside the motor fixing slot 9. The other side of the rotating rod 5 is fixed to the output end of the drive motor 10. The rotating base plate 11 is fixedly connected to the lower end of the raw lacquer filter cylinder 1. The raw lacquer filter cylinder 1 is in an inclined state, and one side of the inlet 2 is higher than one side of the material conveying screen 3. The slag outlet 14 is located at one side of the raw lacquer filter cylinder 1.

[0033] In a specific embodiment of this utility model, a rotating base plate 11 is located at the lower end of the raw lacquer filter cylinder 1 to support the entire device. One side of the rotating base plate 11 can rotate up and down. One end of the rotating rod 5 rotates inside the rotating sleeve 4, while the other end passes through the side wall of the raw lacquer filter cylinder 1 and is fixed to the output end of the drive motor 10. During the raw lacquer filtration process, the rotating base plate 11 rotates the material screen 3 used for lacquer discharge to the lower end of the device. Then, raw lacquer is injected into the raw lacquer filter cylinder 1 through the feed inlet 2. Since the slag outlet 14 is located further back from the feed inlet 2, the raw lacquer will not flow out of the slag outlet 14 after flowing into the raw lacquer filter cylinder 1. At the same time, the drive motor 10 is started to drive the rotating rod 5 and the auger 6 to rotate. The raw lacquer liquid flows through the filter holes 7 on the surface of the auger 6 to the lower end of the material screen 3 and flows out of the raw lacquer filter cylinder. The lacquer is collected within the filter cylinder 1. Fixed impurities in the lacquer cannot pass through the filter holes 7 and are blocked by the blades of the auger 6. As the auger 6 rotates, the solid impurities are pushed upwards and collected. This device has two outlets during lacquer filtration: a material feed screen 3 and a slag outlet 14. The lacquer liquid flows towards the material feed screen 3 through the slightly inclined lacquer filter cylinder 1, while solid impurities move towards the slag outlet 14 under the rotation of the auger 6 and eventually fall out of the slag outlet 14, continuously filtering the lacquer. Through the synergistic effect of the inclined lacquer filter cylinder 1 and the rotating auger 6, the liquid and solid are separated simultaneously. The lacquer liquid flows to the lower material feed screen 3 due to gravity and is discharged through the lacquer outlet 12, while the solid impurities are blocked by the blades of the auger 6 and automatically discharged through the higher slag outlet 14 via a reverse spiral. This process can continuously complete filtration and slag discharge without interrupting operation, significantly improving production efficiency and reducing the need for manual intervention.

[0034] Please refer to the details. Figures 1-5 A paint outlet 12 is provided on one side of the feed mesh 3, and a feed plate 13 is fixedly connected to one side of the feed mesh 3.

[0035] In this embodiment: the paint outlet 12 is opened on one side of the feed screen 3. Raw paint liquid flows out through the paint outlet 12 and filters out fixed impurities. The feed plate 13 is set on one side of the feed screen 3 for guiding the flow and collecting the filtered raw paint liquid into the collection device.

[0036] Please refer to the details. Figures 1-5 The lower end of the rotating base plate 11 is rotatably connected to the side support plate 20 via a rotating shaft, and the lower end of the side support plate 20 is fixedly connected to the support base plate 15.

[0037] In this embodiment: the support base plate 15 is the bottom support plate of the device, which is used to support the whole device. The connection between the side support plate 20 and the rotating base plate 11 is provided with a rotation. The side support plate 20 is sleeved on the outside of the rotating shaft and rotates around the rotating shaft. The orientation of the outlet on one side of the raw lacquer filter cylinder 1 can be controlled by the rotation connection. When filtering raw lacquer, the opening on one side of the material screen 3 can be made to face downwards. When it is necessary to clean the impurities remaining in the auger 6, the slag outlet 14 is rotated downwards and then clean water is injected to clean the residual impurities.

[0038] Please refer to the details. Figures 1-5 A cylinder fixing cylinder 19 is fixedly connected to the upper end of the supporting base plate 15. A telescopic cylinder 18 is fixedly connected inside the cylinder fixing cylinder 19. A sliding rod 17 is fixedly connected to the extended end of the telescopic cylinder 18. The sliding rod 17 is in contact with the lower end of the rotating base plate 11.

[0039] In this embodiment: the telescopic cylinder 18 is equipped with an existing air source system (not shown in the figure, existing technology, and will not be described in detail here) during use. The cylinder fixing cylinder 19 is used to fix the telescopic cylinder 18. The telescopic cylinder 18 is installed at an angle. The sliding rod 17, which is fixed to the output end of the telescopic cylinder 18, is fixed to the other side of the rotating base plate 11. The telescopic cylinder 18 is extended and retracted to make the raw lacquer filter cylinder 1 rotate around the rotating shaft, thereby changing the height position of the material screen 3 and the slag outlet 14, so as to filter the raw lacquer and clean the inside of the raw lacquer filter cylinder 1 respectively.

[0040] Please refer to the details. Figures 1-5 A sliding groove 16 is provided on one side of the rotating base plate 11, and the sliding rod 17 slides in the sliding groove 16.

[0041] In this embodiment, the sliding rod 17 supports the rotating base plate 11 by sliding within the sliding groove 16. When the extension end of the telescopic cylinder 18 extends, the sliding rod 17 slides within the sliding groove 16 to adjust the distance difference generated when the raw lacquer filter cylinder 1 moves in a circular motion around the rotating shaft, thus avoiding motion interference.

[0042] Please refer to the details. Figures 1-5 A material blocking groove 8 is provided on one side of the filter hole 7.

[0043] In this embodiment: the material blocking groove 8 is opened on one side of the filter hole 7, making the filter hole 7 a funnel-shaped filter hole. Fixed impurities cannot pass through the filter hole 7 from the material blocking groove 8. When cleaning, the raw lacquer filter cylinder 1 is rotated so that the opening of the slag outlet 14 faces downward, and clean water enters and exits from the material feed screen 3. The clean water flushes out the fixed impurities blocked in the material blocking groove 8 from the filter hole 7 and discharges them from the slag outlet 14 into the raw lacquer filter cylinder 1.

[0044] The working principle and usage process of this utility model: The rotating base plate 11 is located at the lower end of the raw lacquer filter cylinder 1 to support the entire device. One side of the rotating base plate 11 can rotate up and down. One end of the rotating rod 5 rotates inside the rotating sleeve 4, and the other end passes through the side wall of the raw lacquer filter cylinder 1 and is fixed to the output end of the drive motor 10. When the raw lacquer is being filtered, the rotating base plate 11 rotates the material screen 3 used for discharging lacquer to the lower end of the device. Then, raw lacquer is injected into the raw lacquer filter cylinder 1 through the feed inlet 2. Since the slag outlet 14 is located further back from the feed inlet 2, the raw lacquer will not flow out from the slag outlet 14 after flowing into the raw lacquer filter cylinder 1. At the same time, the drive motor 10 is started to drive the rotating rod 5 and the auger 6 to rotate. The raw lacquer liquid flows through the filter holes 7 on the surface of the auger 6 to the lower end of the material screen 3 and flows out of the raw lacquer filter cylinder 1. The raw lacquer is collected inside the filter cylinder 1. Fixed impurities in the lacquer cannot pass through the filter holes 7 and are blocked by the blades of the auger 6. As the auger 6 rotates, the solid impurities are pushed upwards and collected. This device has two outlets during raw lacquer filtration: a material feed screen 3 and a slag outlet 14. The raw lacquer liquid flows towards the material feed screen 3 through the slightly tilted design of the filter cylinder 1, while solid impurities move towards the slag outlet 14 under the rotation of the auger 6 and eventually fall out of the slag outlet 14, continuously filtering the raw lacquer. Through the synergistic effect of the tilted design of the filter cylinder 1 and the rotating auger 6, the liquid and solid are separated simultaneously. The raw lacquer liquid flows to the lower material feed screen 3 due to gravity and is discharged through the lacquer outlet 12, while the solid impurities are blocked by the blades of the auger 6 and automatically discharged through the higher slag outlet 14 via a reverse spiral. This process can continuously complete filtration and slag discharge without interrupting operation, significantly improving production efficiency and reducing the need for manual intervention.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
