Description

Technical Field

[0001] The utility model relates to the technical field of cationic light-curing varnish processing, in particular to a precise filtering device for cationic light-curing varnish. Background Art

[0002] Cationic photocuring is a common curing technology, widely used in coatings, glues, inks and other fields. It uses cationic curing agents combined with ultraviolet light to achieve rapid curing of materials. It uses ultraviolet light to excite the photoinitiator in the cationic curing agent, so that the positive ions generated by its branching react with the monomer to form a cross-linked structure, thereby achieving the curing of the material. Cationic photocuring varnish is a synthetic resin containing a cationic initiator.

[0003] For example, the utility model with application number CN201921534268.8 discloses an electric clamp-type cold cutting flying saw machine, which is suitable for an electric clamp-type cold cutting flying saw machine. Through the driving gear, the driven gear, the No. 1 motor, the No. 1 flying saw gear and the No. 2 flying saw gear, the flying saw gear can be flexibly moved up and down, and the quantitative flying saw is realized by utilizing the interval between the No. 1 flying saw gear and the No. 2 flying saw gear, thereby improving the mass production and flexibility of an electric clamp-type cold cutting flying saw machine. However, similar to the cold cutting flying saw machine in the above-mentioned document, there is no corresponding structure to assist the saw machine to work while stably displacing. When the equipment is operating, it does not have a structural setting for automatic feeding, and is lacking in overall efficiency and practicality.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a precision filtering device for cationic light-curing varnish is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] like Figures 1 to 5 As shown, a precision filtering device for cationic light-curing varnish comprises a filter cabinet 1 and a filter assembly 4, a lifting assembly 2 is vertically installed on the inner walls on the left and right sides of the filter cabinet 1, and a secondary filter tube assembly 3 is connected to the side of the lifting assembly 2 close to the vertical central axis of the filter cabinet 1, the filter assembly 4 is installed in the inner center of the secondary filter tube assembly 3, and a rotary valve 5 is installed on the top of the secondary filter tube assembly 3, the filter assembly 4 comprises a delivery pipe 401, a filter mesh tube 402, a spiral plate 403 and a cleaning brush 404, the bottom of the delivery pipe 401 is connected to the filter mesh tube 402 of the same diameter, and the surfaces of the delivery pipe 401 and the filter mesh tube 402 are connected to the spiral plate 403, and a cleaning brush 404 is installed on the edge of the side of the spiral plate 403 away from the delivery pipe 401 and the filter mesh tube 402, and the spiral plate 403 and the inner diameter structure of the secondary filter tube assembly 3 They match each other, and the cleaning brush 404 is distributed on the edge surface of the entire spiral plate 403. A discharge assembly 6 is installed on the top of one side of the secondary filter tube assembly 3, and a drain valve 7 is installed on the bottom of one side of the filter cabinet 1. By connecting the entire filter assembly 4 with the rotary valve 5, the entire filter assembly 4 has the axial rotation activity in the vertical direction inside the secondary filter tube assembly 3 under the operation of the rotary valve 5. At the same time, the solidified varnish can be transported to the inside of the filter mesh tube 402 through the delivery pipe 401, and the varnish inside the filter mesh tube 402 is thrown out by centrifugal force during the rotation process, thereby performing primary filtration. At the same time, with the rotation of the delivery pipe 401 and the filter mesh tube 402, the spiral plate 403 will also rotate synchronously, and lift the impurities settled at the bottom of the secondary filter tube assembly 3, so that the discharge assembly 6 can extract and discharge them.

[0026] The lifting assembly 2 includes a guide rod 201, a lifting slider 202 and a docking frame 203. The lifting slider 202 is slidably installed on the surface of the guide rod 201, and the docking frame 203 is installed on the side of the lifting slider 202 close to the secondary filter tube assembly 3. The secondary filter tube assembly 3 includes a long filter tube 301, a first filter screen 302, a second filter plate 303 and an assembly frame 304. The middle section of the long filter tube 301 is provided with a first filter screen 302, and the bottom center of the secondary filter tube assembly 3 is provided with a second filter plate 303. The assembly frame 304 is symmetrically installed on the left and right sides of the lifting slider 202. The mounting frame 304 and the docking frame 203 are structurally detachable, and the long filter tube 301 and the first filter screen 302 are an integrated fixed structure. Through the use of the structure of the lifting component 2, on the one hand, by utilizing the operation of the lifting slider 202, the secondary filter tube assembly 3 structurally connected to it through the docking frame 203 can be vertically lifted and lowered inside the filter cabinet 1. On the other hand, through the detachable structure between the mounting frame 304 and the docking frame 203, the entire secondary filter tube assembly 3 equipped with the filter assembly 4 can be taken out of the filter cabinet 1 as a whole through the use of the lifting component 2.

[0027] The discharge assembly 6 includes an external valve pipe 601, a connecting hose 602, a fixed pipe 603 and an adjusting suction pipe 604. One end of the external valve pipe 601 is connected to the connecting hose 602, and the end of the connecting hose 602 away from the external valve pipe 601 is installed with the fixed pipe 603, and the end of the fixed pipe 603 away from the connecting hose 602 is connected to the adjusting suction pipe 604. The adjusting suction pipe 604 is arranged inside the upper end of the secondary filter tube assembly 3, and the fixed pipe 603 passes through one side of the upper end of the secondary filter tube assembly 3. Through the retractable and bendable structural characteristics of the connecting hose 602, unnecessary structural interference between the external valve pipe 601 and the fixed pipe 603 installed on the side of the long filter tube 301 is avoided due to the driving of the lifting assembly 2 and the lifting and lowering adjustment of the secondary filter tube assembly 3. The adjusting suction pipe 604 can point its open end toward the surface of the spiral plate 403 as much as possible, so as to extract the floating impurities lifted up by the surface of the rotating spiral plate 403 in the most real time.

[0028] In summary, if Figures 1 to 5 As shown, when the precise filtering device for the cationic light-curing varnish is used, the rotary valve 5 is first connected to the upstream feeding device, and the drain valve 7 at the bottom of the side of the filter cabinet 1 is connected to the downstream storage device by a pipeline structure, and then the external valve pipe 601 is connected to the external extraction device, and finally the curing varnish to be filtered is transported to the inside of the filter mesh pipe 402 connected to the bottom of the delivery pipe 401 through the rotary valve 5;

[0029] At this time, under the rotation of the rotary valve 5, the entire filter assembly 4 will perform a uniform axial rotation inside the secondary filter tube assembly 3. As the entire structure rotates, the solidified varnish inside the filter mesh tube 402 will be separated from the filter mesh tube 402 by the centrifugal force generated by the rotation of the structure, and will be filtered by the filter mesh tube 402 for the first level.

[0030] The filtered varnish will then enter the interior of the secondary filter tube assembly 3, and will be filtered twice under the action of the first filter screen 302 and the second filter plate 303 in the middle and bottom of the long filter tube 301, so as to filter the varnish to the greatest extent. After that, the varnish will enter the interior of the filter cabinet 1, and then under the operation of the drain valve 7, the varnish will be transported to the interior of the downstream storage device;

[0031] During the entire process of the filter assembly 4 rotating and filtering the varnish, the spiral plate 403 will lift the impurities accumulated inside the secondary filter tube assembly 3. At the same time, during the rotation of the spiral plate 403, the cleaning brush 404 on the edge surface of the spiral plate 403 will clean the surface of the first filter screen 302 to prevent excessive impurities from adhering to the surface of the first filter screen 302 and causing blockage.

[0032] As the spiral plate 403 rotates, the impurities are lifted to the level of the varnish, that is, the top of the entire filter assembly 4. As the external pumping device operates, the top of the spiral plate 403 is lifted to above the level of the varnish through the transmission of the connecting hose 602, the fixed pipe 603 and the regulating suction pipe 604, and the impurities on the surface are extracted by the adsorption force.

[0033] When it is necessary to maintain and process the secondary filter tube assembly 3 and the filter assembly 4, the secondary filter tube assembly 3 connected to the assembly frame 304 and the docking frame 203 is structurally lifted along the surface of the guide rod 201 by the operation of the lifting slider 202 until it is lifted to the top of the filter cabinet 1. Then, the structural disassembly of the docking frame 203 and the assembly frame 304 is utilized to structurally separate the secondary filter tube assembly 3 from the lifting assembly 2, so that the secondary filter tube assembly 3 and the filter assembly 4 can be taken out as a whole from the inside of the filter cabinet 1 and maintained.

[0034] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
