Description

Technical Field

[0001] The utility model relates to the technical field of line developing section filtering, in particular to a DES line developing section filtering device. Background Art

[0002] The developing section of the DES line protects the bottom layer by exposing and developing the photosensitive material (also known as pressed dry film) on the surface of the film, and then performs etching to remove the film and finally obtain a permanent pattern. The film is developed, acid-etched, cleaned, roughly stripped and finely stripped through the DES production line, where the roughly stripped film and finely stripped film are respectively carried out in the first stripping film section and the second stripping film section.

[0003] In the current prior art, the existing DES line development section uses 100 mesh, 200 mesh and 300 mesh filter screens for filtration. The finer the filter mesh, the smaller the impurities filtered. The finer the filter mesh, the greater the adhesion between the impurities after filtration, and a layer will be formed on the surface of the filter. When flushing with water later, it is easy for fine impurity particles to remain on the surface of the fine mesh. If a brush is used for cleaning, the bristles on the brush surface are larger than the size of the filter mesh holes, which can easily cause the filter mesh holes to be squeezed and expanded, affecting the size of the filter mesh holes and making the filtering effect worse.

[0004] To this end, the utility model provides a DES line developing section filtering device. Utility Model Content

[0005] To this end, the technical problem to be solved by the utility model is to overcome the problem in the prior art that impurities are easily left in the fine filter plate after cleaning, and the bristles of the brush are larger than the filter holes between the filter screens, which can easily cause the filter holes on the surface of the fine filter screen to be enlarged, affecting the size of the filter screen holes and making the filtering effect worse.

[0006] In order to solve the above technical problems, the utility model provides a DES line developing section filtering device, comprising: a drying and heating box and a pull-out box movably sleeved on the inner wall surface of the drying and heating box, an air induction plate is fixedly connected to the inner wall surface of one side of the pull-out box, a blower is detachably installed on the bottom surface of the other side of the drying and heating box, and a heating rod is fixedly installed on the inner wall surface of the bottom of the drying and heating box and at the edge of the output end of the blower;

[0007] A filter drying and cleaning unit is provided on the inner wall surface of the other side of the pull-out box, and the filter drying and cleaning unit includes an overlapping limit strip fixedly connected to the inner wall surface of one side of the pull-out box, and a plurality of groups of elastic threads are fixedly connected to the inner surface of the overlapping limit strip, and a overlapping platform is fixedly connected to one end of the plurality of groups of elastic threads, and a lower swing positioning plate is provided on one side surface of the pull-out box and on the bottom surface of the elastic threads, and an upper swing limit strip movably overlapped on the edge position of one side of the top of the overlapping platform is fixedly connected to the outer top edge position of the overlapping limit strip, and a multi-mesh filter plate is movably sleeved inside the overlapping platform.

[0008] In an embodiment of the utility model, the number of the air guide plates and the overlapping limit strips is set to multiple groups, and the multiple groups of the air guide plates and the overlapping limit strips are interlaced and sleeved with each other.

[0009] In one embodiment of the utility model, the top surface of the lower swing positioning plate is movably overlapped on the bottom surface of the overlapping platform, and the number of the upper swing limiting strips is arranged in a plurality of groups.

[0010] In one embodiment of the utility model, filter positioning strips are symmetrically and fixedly connected to the inner walls of both sides of the overlapping platform, and the surface of the multi-mesh filter plate is movably overlapped on the inner wall surface of the filter positioning strip.

[0011] In one embodiment of the present invention, a filter screen is provided on the bottom surface of the pull-out box, and an exhaust screen is provided on the top surface of the pull-out box and at one side edge.

[0012] In one embodiment of the utility model, a limited overlap platform is fixedly connected to the front side of the drying and heating box and located at the bottom edge of one side, and the bottom surface of the pull-out box is movably overlapped on the top surface of the limited overlap platform.

[0013] In one embodiment of the utility model, a return air pipe is fixedly connected to the top surface of the drying and heating box, and the other end of the return air pipe is arranged at the edge of the air inlet of the blower.

[0014] In one embodiment of the utility model, a filter sponge layer is movably sleeved on the inner wall surface of the return air pipe.

[0015] The above technical solution of the utility model has the following advantages compared with the prior art:

[0016] The utility model discloses a DES line developing section filtering device. After filtering the impurities inside the DES line, the multi-mesh filter plates of 100 mesh, 200 mesh and 300 mesh are disassembled from the inside of the filtering device, and are washed from the back of the multi-mesh filter plates with a small amount of water through a water pipe. Under the promotion of the water source, most of the impurities adhering to the surface of the multi-mesh filter plates are washed down first by reverse washing, and then the multi-mesh filter plates with impurities remaining on the surface are clamped to the inside of the lap table for fixing, the pull-out box is moved to the inner wall of the drying and heating box, the entrance of the drying and heating box is closed, the heating rod is energized for continuous heating, and the outside air is intermittently guided into the inside of the drying and heating box in a pulsed manner in conjunction with the blower, so as to achieve the effect of continuously and intermittently impacting the airflow in a pulsed manner, and each impact will impact and push the front airflow for a second time, thereby accelerating the airflow movement speed.

[0017] The utility model discloses a filtering device for the developing section of a DES line. When the hot air flow flows at a high speed, the hot air flow will be briefly stagnant between the lap joint table and the air induction plate because the air flow is changing its path and direction. Then, under the impetus of the subsequent air flow, the hot air flow will be mixed with the previously briefly stagnant air flow. The mixed air flow will be briefly expanded, and then the air flow will generate an upward driving force on the lap joint table, so that the lap joint table will swing upward on one end of the elastic wire. In addition, the blower blows air in a pulsed manner, and the air flow will have a certain periodic stagnation. When the air flow blows the lap joint table, there will be a brief weak window period in the air flow. By utilizing the lap joint table itself, the lap joint table can be effectively controlled. The gravity will cause it to fall and hit the surface of the lower hem positioning plate. The slight impact force generated by the impact will be transmitted to the surface of the multi-mesh filter plate, causing the impurities that are being continuously dried on the multi-mesh filter plate to be separated from the surface of the multi-mesh filter plate little by little during the vibration, so that the impurities are detached from the surface of the multi-mesh filter plate, thereby achieving the effect of continuously and intermittently impacting the airflow in a pulsed manner. The expansion of the airflow generated by each impact will lift the bottom surface of the lap table, causing the fall to produce impact vibration. After the top surface of the lap table is impacted, the suddenly expanded airflow will accelerate the fall of the lap table and impact the impurities on the surface of the multi-mesh filter plate, thereby accelerating the scattering effect.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 6 As shown, a DES line developing section filtering device of the utility model comprises: a drying and heating box 11 and a drawer box 12 movably sleeved on the inner wall of the drying and heating box 11, a blower 112 is detachably mounted on the bottom surface of the other side of the drying and heating box 11, a heating rod 115 is fixedly mounted on the inner wall of the bottom of the drying and heating box 11 and at the edge of the output end of the blower 112; an air induction plate 123 is fixedly connected to the inner wall of one side of the drawer box 12; a filter drying and cleaning unit is arranged on the inner wall of the other side of the drawer box 12, and the filter drying and cleaning unit The management unit includes an overlapping limit strip 122 fixedly connected to the inner wall surface of one side of the pull-out box 12, a plurality of groups of elastic threads a3 are fixedly connected to the inner surface of the overlapping limit strip 122, an overlapping platform a4 is fixedly connected to one end of the plurality of groups of elastic threads a3, a lower swing positioning plate a1 is provided on one side surface of the pull-out box 12 and on the bottom surface of the elastic threads a3, an upper swing limit strip a2 movably overlapped on one side edge of the top of the overlapping platform a4 is fixedly connected to the outer top edge of the overlapping limit strip 122, and a multi-mesh filter plate a6 is movably sleeved inside the overlapping platform a4.

[0029] During operation, after filtering out the impurities inside the DES line display, remove the 100-mesh, 200-mesh and 300-mesh multi-mesh filter plates a6 from the inside of the filtering device, and rinse them from the back of the multi-mesh filter plate a6 with a small amount of water through a water pipe. Since the impurities will preferentially adhere to the positive surface of the filter when filtering, most of the impurities adhering to the surface of the multi-mesh filter plate a6 will be preferentially rinsed off under the push of the water source during reverse flushing, and then the multi-mesh filter plate a6 with impurities remaining on the surface will be clamped to the inside of the lap table a4 for fixation, and the pull-out box 12 will be moved to the drying and heating box On the inner wall of 11, the entrance of the drying and heating box 11 is closed, and the heating rod 115 is powered on for continuous heating, and the blower 112 is used to intermittently guide the outside air into the drying and heating box 11 in a pulsed manner, so as to achieve the effect of continuously and intermittently impacting the airflow in a pulsed manner. Each impact will have a secondary impact and push on the front airflow, thereby accelerating the speed of the airflow. When the wind source flows inside the drying and heating box 11, it will drive the heat source on the surface of the heating rod 115 to blow, and the airflow carrying the heat source will flow inside the drawer box 12, such as Figure 4 As shown, when the airflow is flowing, the overlapping platform a4 and the air induction plate 123 increase the path of the flowing airflow, so that the hot airflow can continuously contact and heat the multi-mesh filter plate a6 on the surface of the overlapping platform a4;

[0030] When thermal air flows at high speed, Figure 4As shown, there will be a section of downward flow path that fits the bottom surface of the lap platform a4 and the top surface of the air guide plate 123. When the hot air flow flows between the lap platform a4 and the air guide plate 123, the air flow will be briefly stagnant in the process of changing its path and direction, and then, under the impetus of the subsequent air flow, it will mix with the previous briefly stagnant air flow. The mixed air flow will expand briefly. Since the air guide plate 123 is fixed to the inner wall of the drying and heating box 11 and will not swing as a whole, the air flow will generate an upward driving force on the lap platform a4. Since the lap platform a4 is fixedly connected to the surface of the lap limit strip 122 by the elastic wire a3, and the elastic wire a3 is made of elastic material, it will swing and deform at a small angle when encountering external force, so that the lap platform a4 swings upward on one end of the elastic wire a3, and the blower 112 blows air in a pulsed form, the air flow will have a certain stage, so that the air flow will be blown When the overlapped platform a4 is in the window period of airflow weakness, the overlapped platform a4 will fall by its own gravity and hit the surface of the lower hem positioning plate a1. The slight impact force generated by the impact will be transmitted to the surface of the multi-mesh filter plate a6, so that the impurities on the multi-mesh filter plate a6 that are being dried continuously are separated from the surface of the multi-mesh filter plate a6 little by little during the vibration, and then the hot air flow is used to accelerate the separation speed. After the impurities are completely dried, the impurities are separated from the surface of the multi-mesh filter plate a6 under the continuous impact and are cleaned up under the drive of the hot air flow, achieving the effect of continuous and intermittent impact on the airflow in a pulsed manner. The expansion of the airflow generated by each impact will lift the bottom surface of the overlapped platform a4, and the fall will produce impact vibration. After the top surface of the overlapped platform a4 is impacted, the suddenly expanded airflow will accelerate the falling of the overlapped platform a4 and impact the impurities on the surface of the multi-mesh filter plate a6, thereby accelerating the scattering effect.

[0031] Further, such as Figures 1 to 6As shown, the number of the air induction plates 123 and the overlap limit strips 122 is set in multiple groups, and the multiple groups of air induction plates 123 and the overlap limit strips 122 are interlaced and sleeved with each other, the top surface of the lower swing positioning plate a1 is movably overlapped on the bottom surface of the overlap platform a4, the number of the upper swing limit strips a2 is set in multiple groups, the inner wall surfaces on both sides of the overlap platform a4 are symmetrically fixedly connected with the filter positioning strips a5, the surface of the multi-mesh filter plate a6 is movably overlapped on the inner wall surface of the filter positioning strip a5, and the bottom surface of the drawer box 12 is provided with a filter screen plate 121, An exhaust mesh plate 124 is provided on the top surface of the pull-out box 12 and at one side edge position, a limited overlap platform 111 is fixedly connected to the front side of the drying and heating box 11 and at one side bottom edge position, the bottom surface of the pull-out box 12 is movably overlapped on the top surface of the limited overlap platform 111, a return air pipe 113 is fixedly connected to the top surface of the drying and heating box 11, the other end of the return air pipe 113 is provided at the edge of the air inlet of the blower 112, and a filter sponge layer 114 is movably sleeved on the inner wall surface of the return air pipe 113.

[0032] During operation, when the multi-mesh filter plate a6 is put into the overlapping platform a4, the filter positioning strip a5 is used to clamp the bottom edge positions of the multi-mesh filter plate a6. The thickness of the filter positioning strip a5 is used to leave a cavity between the multi-mesh filter plate a6 and the overlapping platform a4. When the airflow hits the surface of the multi-mesh filter plate a6, the airflow will pass through the surface of the multi-mesh filter plate a6 into the cavity, and then flow along the cavity and the top surface of the multi-mesh filter plate a6 to be discharged. When the hot airflow passes through the surface of the multi-mesh filter plate a6, the airflow will take away the residual water vapor on the surface of the multi-mesh filter plate a6 and The moisture inside the impurities achieves the effect of drying the multi-mesh filter plate a6 both inside and outside at the same time, thereby accelerating the drying speed of the impurities. As the hot air flow continues to accumulate inside the drying and heating box 11, the return air pipe 113 is used to guide the hot air flow accumulated inside the drying and heating box 11. When the air flow passes through the filter sponge layer 114, the filter sponge layer 114 is used to effectively filter out the impurities and water vapor inside the air flow. The blower 112 is used to absorb a portion of the hot air discharged from the return air pipe 113, and it is redirected into the drying and heating box 11 to make secondary use of the hot air.

[0033] Working principle: After filtering the impurities inside the DES line display, remove the 100-mesh, 200-mesh and 300-mesh multi-mesh filter plates a6 from the inside of the filtering device, and rinse them from the back of the multi-mesh filter plate a6 with a small amount of water through a water pipe. The reverse flushing will preferentially rinse off most of the impurities on the surface of the multi-mesh filter plate a6, and then the multi-mesh filter plate a6 with impurities remaining on the surface is clamped to the inside of the lap table a4 for fixation, and the pull-out box 12 is moved to the inner wall of the drying and heating box 11, and the entrance of the drying and heating box 11 is closed and sealed. The heating rod 115 is energized for continuous heating, and the machine is started. The outside air is intermittently guided into the drying and heating box 11 in a pulsed manner in conjunction with the blower 112. When the wind source flows inside the drying and heating box 11, it will drive the heat source on the surface of the heating rod 115 to blow, and the airflow carrying the heat source flows inside the pull-out box 12, such as Figure 4 As shown, when the airflow is flowing, the overlapping platform a4 and the air induction plate 123 increase the path of the flowing airflow, so that the hot airflow can continuously contact and heat the multi-mesh filter plate a6 on the surface of the overlapping platform a4;

[0034] When the hot air flows at a high speed, the hot air will be temporarily stagnant between the overlapping platform a4 and the air guide plate 123 because the air flow is changing its path and direction. Then, under the impetus of the subsequent air flow, it will mix with the previous briefly stagnant air flow. The mixed air flow will expand briefly, and then the air flow will generate an upward driving force on the overlapping platform a4. Since the overlapping platform a4 is fixedly connected to the surface of the overlapping limit strip 122 by the elastic wire a3, and the elastic wire a3 is made of elastic material, it will swing and deform at a small angle when encountering external force, so that the overlapping platform a4 swings upward on one end of the elastic wire a3, and the blower 112 is in the form of pulses to blow one by one. The air flow will stagnate at certain stages when blowing the overlapping platform a4, so that the air flow will have a short weak window period when blowing the overlapping platform a4, and will fall by the gravity of the overlapping platform a4 itself, thereby hitting the surface of the lower hem positioning plate a1, and the slight impact force generated by the impact will be transmitted to the surface of the multi-mesh filter plate a6, so that the impurities that are being continuously dried on the multi-mesh filter plate a6 are separated from the surface of the multi-mesh filter plate a6 little by little during the vibration, and then the hot air flow is used to promote the separation speed. After the impurities are completely dried, they are separated from the surface of the multi-mesh filter plate a6 under the continuous impact and are cleaned up under the drive of the hot air flow.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
