[0022] Please see Figs. 1 to 3 A pressure filter for ultraviolet absorbers includes a housing 1, a fixed cylinder 2 is installed through the upper end face of the housing 1, a first motor 3 is installed on the upper end face of the fixed cylinder 2, the output end of the first motor 3 passes through the upper end face of the fixed cylinder 2 and is equipped with a screw rod 301, a mesh 201 is opened through the outer wall of the section of the fixed cylinder 2 inside the housing 1, and a feed pipe 202 that passes through the bottom of the housing 1 is connected to the bottom of the fixed cylinder 2.

[0023] A conveyor 5 is installed below the feed pipe 202. The outer wall of the conveyor belt of the conveyor 5 is mesh-like. A fixed frame 6 is installed on the upper end face of the conveyor 5. An electric push rod 601 is installed on the upper end face of the fixed frame 6. The output end of the electric push rod 601 passes through the upper end face of the fixed frame 6 and is installed with a mounting frame 602. A pressure roller 603 is installed inside the mounting frame 602. A mesh plate 501 is installed between the front and rear end faces inside the conveyor 5, located inside the conveyor belt and directly below the pressure roller 603.

[0024] In this embodiment: the ultraviolet absorber that needs to be impurity removed is fed into the fixed cylinder 2 through the feed pipe, and the first motor 3 is started through the operation panel, so that the screw rod 301 rotates to transport and squeeze the ultraviolet absorber. The ultraviolet absorber squeezed out from the impurities falls into the bottom of the box 1 through the mesh 201 and flows into the conveying cylinder 4 through the pipe. The impurities in the fixed cylinder 2 are squeezed out from the discharge pipe 202 by the pressure filter of the screw rod 301, and fall onto the conveyor belt of the conveyor 5. The conveyor belt in the conveyor 5 transports the filter residue. At the same time, the electric push rod 601 is started, which can push the mounting frame 602 and the pressure roller 603 to move down, further pressing the filter residue. The ultraviolet absorber remaining in the filter residue falls into the collection box 701 through the discharge pipe 7 for collection, and facilitates the discharge of the filter residue.

[0025] By starting the second motor 401, the screw conveyor 402 rotates to transport the ultraviolet absorber, which is then further filtered by the filter screen. The filtered filter residue is then transported by the screw conveyor 402 and discharged from the slag discharge pipe, thus facilitating the automatic discharge of the filter residue. The filtered ultraviolet absorber falls into the collection box 404 through the discharge pipe 403 for collection.

[0026] As a technical optimization of this utility model, the left side wall of the box 1 is connected to the conveying cylinder 4 through a pipe, the bottom of the conveying cylinder 4 is installed with a filter screen, and the left side wall is equipped with a second motor 401. The output end of the second motor 401 passes through the outer side wall of the conveying cylinder 4 and is equipped with a spiral conveying rod 402.

[0027] In this embodiment: by starting the second motor 401, the screw conveyor 402 can be driven to rotate to convey impurities.

[0028] As a technical optimization of this utility model, a slag discharge pipe is connected to the bottom of the left side wall of the conveying cylinder 4, and a discharge pipe 403 is installed on the bottom end face. A collection box 404 is set below the discharge pipe 403.

[0029] In this embodiment, by setting up a discharge pipe 403, it is convenient to discharge the filtered ultraviolet absorber into the collection box 404 for collection.

[0030] As a technical optimization of this utility model, a scraper that abuts against the outer wall of the conveyor belt is installed on the right end of the bottom surface inside the conveyor 5, and a discharge pipe 7 is connected to the bottom. A receiving box 701 is set below the discharge pipe 7.

[0031] In this embodiment: by setting a scraper, when the conveyor belt of the conveyor transports the filter residue, it is easy to remove the filter residue on the conveyor belt. By setting a receiving box 701, it is easy for the discharge pipe 7 to discharge the filtered impurities into the receiving box 701 for collection.

[0032] As a technical optimization of this utility model, the outer wall of the fixed cylinder 2 is connected to the feed pipe located above the box body 1.

[0033] In this embodiment: by setting up a feed pipe, it is convenient to pass the ultraviolet absorber into the fixed cylinder 2 for pressure filtration.

[0034] As a technical optimization of this utility model, multiple support legs are installed at the bottom of the box 1, the conveyor 5, and the conveying cylinder 4.

[0035] In this embodiment, multiple support legs are provided to facilitate the support of the box 1, the conveyor 5, and the conveyor cylinder 4.

[0036] Working principle: First, connect the device to an external power source and an external control panel. Then, feed the UV absorber that needs to be purified into the fixed cylinder 2 through the feed pipe. Start the first motor 3 through the control panel to rotate the screw rod 301 and transport the UV absorber. Since the port of the discharge pipe 202 is narrowed (the size of the feed pipe is larger than the size of the discharge pipe 202, that is, the speed at which the UV absorber is added to the fixed cylinder 2 is greater than the speed at which the filter residue is discharged from the discharge pipe 202), the screw rod 301 transports the UV absorber while squeezing it. The UV absorber squeezed out from the impurities falls into the bottom of the box 1 through the mesh 201 and flows into the conveying cylinder 4 through the pipe. The impurities in the fixed cylinder 2 are squeezed out from the discharge pipe 202 by the pressure of the screw rod 301 and fall onto the conveyor belt of the conveyor 5.

[0037] By starting the second motor 401, the screw conveyor 402 rotates to transport the ultraviolet absorber, which is then further filtered by the filter screen. The filtered residue is then discharged from the slag discharge pipe via the screw conveyor 402, and the filtered ultraviolet absorber falls into the collection box 404 through the discharge pipe 403 for collection.

[0038] When the filter residue falls onto the conveyor belt of conveyor 5, the conveyor belt inside conveyor 5 transports the filter residue. At the same time, the electric actuator 601 is activated, which can push the mounting frame 602 and the pressure roller 603 to move down, further pressing the filter residue. This allows the residual ultraviolet absorber in the filter residue to fall into the collection box 701 through the discharge pipe 7 for collection. Finally, the filter residue is discharged after being removed by the scraper when the conveyor belt of conveyor 5 transports it.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
