Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter for color coated plate processing. Background Technique

[0002] The basic concept of color coated plate is that on a continuous unit, cold rolled strip steel and galvanized strip steel (electro galvanized and hot galvanized) are used as substrates. After surface pretreatment (degreasing and chemical treatment), one or more layers of liquid coatings are applied by roll coating method. The plate obtained after baking and cooling is the coated steel plate. Filters are needed to filter the air during the processing of color coated plates.

[0003] For example, a filter for color coated plate processing with the application number CN201911178257.5. By setting a replacement mechanism, the pull ring drives the limit shell to move out of the replacement box. At the same time, the limit shell drives the positioning block to slide inside the positioning groove, so as to limit the movement track of the limit shell. Then, a suitable air filter element can be selected according to the type of surrounding pollutants and snapped into the limit groove. Then, the limit shell is pushed into the replacement box. Multiple air filter elements can be added according to the filtration needs, and the distance between the air filter elements can be adjusted according to the needs, so as to control the filtration effect of the air filter element. Then, the air enters the replacement box through the air circulation port, is filtered by the air filter element and discharged. It can effectively replace the filter element quickly according to the type of surrounding pollutants and improve the convenience of filtration. By setting a fixing mechanism, the pull plate drives the lifting rod to move upward through the pull rod. Then, the lifting rod drives the positioning pin to slide inside the positioning slide hole through the connecting rod. Then, the top sealing plate is snapped into the groove at the top of the filter box body. Then, the pull plate is released, and the spring drives the positioning pin to extend into the positioning slide hole through the fixed clamping plate. Then, the positioning pin is snapped into the fixing hole, so as to fix the replacement box and the filter box body, effectively improving the convenience of fixing the replacement box and the filter box body.

[0004] However, there are still the following defects in this device and the existing technology: most of the suction range of the filter is carried out through a set of suction pipes, resulting in the whole device being unable to absorb the gas generated during the processing of color coated plates in a large range and quickly, reducing the overall filtration range and filtration efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0031] Please refer to Figure 1 ,the present utility model provides a technical solution for a filter for color - coated board processing, including a filter box body 1. Inside the filter box body 1, there is a fixedly connected mounting plate 2. At the upper end of the mounting plate 2, there is a fixedly connected fan 3 for sucking air. At the air suction port of the fan 3, there is a fixedly connected four - way pipe 4. At both ends of the four - way pipe 4, there are fixedly connected fixed side pipes 5. At the upper end of the four - way pipe 4, there is a fixedly connected air suction pipe 6. At the lower end of the mounting plate 2, there is a fixedly connected filtering mechanism 7 for filtering the gas generated during color - coated board processing. The air outlet of the fan 3 extends through the mounting plate 2 to the lower side of the mounting plate 2. Inside the fixed side pipe 5, there is a movably connected movable pipe 51. At the end of the movable pipe 51 away from the fixed side pipe 5, there are symmetrically distributed fixedly connected air suction branch pipes 52. The air suction branch pipes 52 can suck the horizontal gas, and the movable pipe 51 can also move inside the fixed side pipe 5, thus facilitating the overall suction and filtration of air in a larger range.

[0032] Refer to Figure 3, a sealing shaft sleeve 53 is fixedly connected to the outside of the movable pipe 51. The movable pipe 51 is movably connected to the fixed side pipe 5 through the sealing shaft sleeve 53. The sealing shaft sleeve 53 is adapted to the inner wall of the fixed side pipe 5. The movable pipe 51 moves inside the fixed side pipe 5 through the sealing shaft sleeve 53, so as to ensure that there is no air leakage during the movement of the movable pipe 51. An actuating cylinder 54 is fixedly connected to the outside of the filter box body 1. A connecting block 55 is fixedly connected to the movable end of the actuating cylinder 54. The connecting block 55 is fixedly connected to the movable pipe 51. The movable end of the actuating cylinder 54 is fixedly connected to the movable pipe 51 through the connecting block 55. The actuating cylinder 54 drives the movable pipe 51 to move inside the fixed side pipe 5 through the connecting block 55, so as to ensure that the position of the suction branch pipe 52 keeps changing, that is, the suction point keeps changing, increasing the overall suction range.

[0033] Refer to Figure 2 , inside the filtering mechanism 7, there are multiple groups of clamping frames 71 longitudinally and equidistantly fixed on the inner wall of the filter box body 1. An installation groove 72 is formed inside the clamping frame 71. A filter frame 73 is detachably connected inside the installation groove 72. A filter element 74 is fixedly connected inside the filter frame 73. An embedded handle 75 is arranged on the side wall of the filter frame 73. The clamping frame 71 is a rectangular frame structure with two hollow interiors. The clamping frame 71 is located below the installation plate 2. Multiple groups of clamping frames 71 longitudinally and equidistantly fixed on the inner wall of the filter box body 1 can fix multiple groups of filter frames 73 to achieve the overall combined filtration. At the same time, the filter frames 73 with different filter elements 74 can be replaced according to the actual situation to ensure the overall good filtration effect. A box door 11 is hingedly connected to the front end of the filter box body 1. A sealing groove 12 is formed on one side of the filter box body 1 close to the box door 11.

A fixed lock core 14 is fixedly connected to the outside of the box door 11. A fixed lock hole 15 adapted to the fixed lock core 14 is fixedly connected to the side wall of the filter box body 1. When the box door 11 is closed, the box door 11 needs to be attached to one side of the clamping frame 71, so as to ensure the overall good filtration effect, that is, the gas can only pass through the filter element 74. Exhaust holes 16 for discharging air are formed at the bottom ends of the four walls of the filter box body 1. The exhaust holes 16 are equidistantly distributed on the four walls of the filter box body 1. The exhaust holes 16 equidistantly distributed at the bottom ends of the four walls of the filter box body 1 can allow air to pass through, ensuring that the filtered air is quickly discharged through the exhaust holes 16 to complete the filtration.

[0034] Working principle: First, the fan 3 applies suction force to the fixed side pipe 5 and the suction pipe 6 through the four-way pipe 4. At the same time, the movable cylinder 54 drives the movable pipe 51 to move inside the fixed side pipe 5 through the connecting block 55, so as to ensure that the position of the suction branch pipe 52 is constantly changing, that is, the suction points are constantly changing, increasing the overall suction range. And the movable pipe 51 moves inside the fixed side pipe 5 through the sealing shaft sleeve 53, so as to ensure that there is no air leakage during the movement of the movable pipe 51. The fan 3 discharges the sucked gas to the filtering mechanism 7 for filtering, that is, the gas is discharged to the exhaust hole 16 through the filter element 74 in the filter frame 73 and returns to the air to complete the filtering. At the same time, multiple groups of clamping frames 71 fixed longitudinally and equidistantly on the inner wall of the filter box 1 can fix multiple groups of filter frames 73 to achieve the overall combined filtering. At the same time, the filter frames 73 with different filter elements 74 can also be replaced according to the actual situation to ensure the overall good filtering effect.
