Description

Technical Field

[0001] This utility model relates to the field of paint production and processing, and in particular to an impurity filter in paint production and processing. Background Technology

[0002] In the paint production and processing industry, impurity filtration is a crucial step in ensuring the quality of paint products. Various impurities may be mixed into paints, such as incompletely dispersed pigment particles, fibers introduced during the production process, dust, and tiny solid impurities inherent in the raw materials.

[0003] Current methods for filtering impurities in paint production typically involve using filter bags or screens inside a filter canister. During filtration, increasing air pressure within the filter canister accelerates the flow of the paint, enabling faster filtration. However, since the filter canister only contains one filter bag or screen, the filtration efficiency is low when filtering large quantities of paint using only one filter bag or screen. Furthermore, the large internal space of the filter canister can lead to higher energy consumption when processing small quantities of paint, making it inconvenient.

[0004] Therefore, it is necessary to design a filter press for impurities in paint production and processing that can control the number of filter sleeves opening and closing according to the amount of paint, so as to adapt to different filtration needs, achieve high-efficiency filtration while reducing energy consumption. Utility Model Content

[0005] To overcome the shortcomings of existing impurity filtration methods in paint production and processing, which only have one filter bag or filter screen installed inside the filter tank, resulting in low filtration efficiency when filtering a large amount of paint, and potentially higher energy consumption when processing small amounts of paint due to the large internal space of the filter tank, this utility model provides an impurity filter for paint production and processing that can control the number of filter sleeves opening and closing according to the amount of paint, making it easy to adapt to different filtration needs and achieving high-efficiency filtration while reducing energy consumption.

[0006] The technical solution of this utility model is: a filter for impurities in paint production and processing, comprising a base frame, a booster pump, an air supply pipe, a filter barrel, a rotating rod, a cover, a rotating screw, a nut, a valve, and a filter assembly. The booster pump is connected to the front right side of the base frame, and the air supply pipe is connected to the booster pump. The filter barrel is connected to the upper part of the base frame, and the air supply pipe is connected to the filter barrel. The rotating rod is rotatably connected to the upper left side of the base frame, and the cover is connected to the lower right side of the rotating rod. The filter barrel is rotatably connected to the four sides (front, back, left, and right), and the upper part of each rotating screw is threadedly connected to a nut, which contacts the cover. A valve is provided on the front right side of the filter barrel, and a filter assembly capable of high-efficiency filtration is provided inside the filter barrel.

[0007] Furthermore, the filter canister has a structure that is wider at the top and narrower at the bottom.

[0008] Furthermore, it also includes a feed pipe, which is connected to the front side of the middle part of the filter barrel.

[0009] Furthermore, the filter assembly includes a filter sleeve, a support plate, a sleeve, a pressing rod, an extrusion element, an extrusion block, a connecting rod, and a spring. The lower inner side of the filter barrel is connected to the support plate, and multiple filter sleeves are connected to the upper side of the support plate. Multiple sleeves are connected to the support plate, and multiple locking grooves are opened on the upper inner side of the sleeve. Multiple sliding grooves are opened inside the sleeve, and the upper part of the sleeve is slidably connected to the pressing rod through the sliding groove. An extrusion element is connected to the lower side of the pressing rod, and a connecting rod is sleeved on the lower part of the sleeve. Multiple extrusion blocks are connected to the upper part of the connecting rod, and each extrusion block is in contact with an adjacent extrusion element. A spring is placed between each connecting rod and an adjacent sleeve.

[0010] Furthermore, all extrusion blocks are wedge-shaped.

[0011] Furthermore, it also includes a collection box, which is placed at the bottom of the base frame.

[0012] The beneficial effects are: by pressing the pressing rod, the connecting rod is forced to rotate by the squeezing of the extruder. When the pressing rod contacts the upper side of the filter sleeve, the pressing rod is released, causing the connecting rod to move upward and the filter sleeve to close. This allows the number of times the filter sleeve is opened and closed to be controlled according to the amount of coating, which is convenient to adapt to different filtration needs and achieves the effect of high-efficiency filtration while reducing energy consumption.

Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] A filter for impurities in paint production and processing, such as Figure 1 and Figure 2 As shown, the system includes a base frame 1, a booster pump 2, an air supply pipe 3, a filter barrel 4, a feed pipe 5, a rotating rod 6, a cover 7, a rotating screw 8, a nut 9, a valve 10, a collection frame 18, and a filter assembly. The booster pump 2 is connected to the front right side of the base frame 1, and the air supply pipe 3 is connected to the booster pump 2. The filter barrel 4 is connected to the upper part of the base frame 1. The filter barrel 4 has a structure that is wider at the top and narrower at the bottom, which facilitates material feeding. The air supply pipe 3 is connected to the filter barrel 4. The feed pipe 5 is connected to the front side of the middle part of the filter barrel 4. The rotating rod 6 is rotatably connected to the upper left side of the base frame 1. The cover 7 is connected to the lower right side of the rotating rod 6. The rotating screw 8 is rotatably connected to the front, rear, left, and right sides of the filter barrel 4. The upper part of the rotating screw 8 is threaded with a nut 9, and the nut 9 is in contact with the cover 7. The valve 10 is located on the front right side of the filter barrel 4. The collection frame 18 is placed at the bottom inside the base frame 1. The filter assembly is located inside the filter barrel 4.

[0022] like Figures 2-6 As shown, the filter assembly includes a filter sleeve 11, a support plate 111, a sleeve 12, a pressing rod 13, an extrusion piece 131, an extrusion block 14, a connecting rod 15, and a spring 16. The lower inner side of the filter barrel 4 is connected to the support plate 111, and nine filter sleeves 11 are connected to the upper side of the support plate 111. Nine sleeves 12 are connected to the support plate 111. Eight locking grooves 17 are opened on the upper inner side of the sleeve 12, and eight sliding grooves 19 are opened inside the sleeve 12. The pressing rod 13 is slidably connected to the upper part of the sleeve 12 through the sliding grooves 19. The extrusion piece 131 is connected to the lower side of the pressing rod 13. The connecting rod 15 is sleeved on the lower part of the sleeve 12. Four extrusion blocks 14 are connected to the upper part of the connecting rod 15. The extrusion blocks 14 are all wedge-shaped structures and each extrusion block 14 is in contact with the adjacent extrusion piece 131. A spring 16 is placed between each connecting rod 15 and the adjacent sleeve 12.

[0023] When using this device, first place the base frame 1 in the paint production and processing area, then connect the feed pipe 5 to the external conveying pipe to allow the paint to enter the filter tank 4 through the feed pipe 5 and into the filter sleeve 11. At the same time, start the booster pump 2 to allow gas to enter the filter tank 4 through the gas delivery pipe 3, applying a certain pressure to the filter tank 4, so that the paint can be discharged more quickly from the filter sleeve 11 onto the support plate 111, and then discharged from the bottom of the filter tank 4 into the collection frame 18. The paint is quickly filtered through multiple filter sleeves 11, improving production efficiency. During the pressurization process, if the pressure is too high, the valve 10 can be turned to open, allowing the gas to be discharged slowly from the valve 10 to avoid excessive air pressure inside the filter tank 4. When the amount of paint to be filtered is small, the nut 9 can be loosened by turning it, then the rotating screw 8 can be turned downwards, and then the cover 7 can be turned to open, driving the rotating rod 6 to rotate. Then the pressing rod 13 can be pressed, driving the extruder 131 to slide along the groove. The 19 moves downward, causing the extruder 131 to press the extrusion block 14, which in turn moves the extrusion block 14 downward along the slide groove 19. This causes the connecting rod 15 to move downward, and the spring 16 is compressed and contracts. When the extrusion block 14 disengages from the slide groove 19 on the sleeve 12, the extruder 131 forces the connecting rod 15 to rotate. When the pressing rod 13 contacts the upper side of the filter sleeve 11, the pressing rod 13 is released, the spring 16 returns to its original state, and the connecting rod 15 moves upward, causing the extrusion block 14 to engage with the locking groove 17, thus closing the filter sleeve 11. The number of times the filter sleeve 11 is opened and closed is controlled according to the amount of paint, so that the paint is discharged only from the open filter sleeve 11. This results in a shorter fluid flow path and lower fluid resistance, thus requiring less pumping pressure and reducing energy consumption. This allows the number of times the filter sleeve 11 is opened and closed to be controlled according to the amount of paint, making it easy to adapt to different filtration needs and achieve high-efficiency filtration while reducing energy consumption.
