Description

Technical Field

[0001] The utility model relates to the field of purification, and more specifically, to an impurity purification device for a leveling agent. Background Art

[0002] Leveling agent is a commonly used coating additive, and its English professional name is Leveling Agent. Leveling agent mainly acts on the coating system, by reducing the surface tension of the coating and improving its fluidity, so as to form a flat, smooth and uniform coating film during the drying and film-forming process, and reduce surface defects such as ripples, orange peel, brush marks, pinholes, shrinkage holes and other problems; in the preparation process of leveling agent, after the raw materials are dissolved and the polymerization reaction is completed, it is usually necessary to go through a filtering step to remove unreacted impurities, by-products in the polymerization process, and solid particles that may be generated in the polymerization process, so as to ensure the purity and uniformity of the leveling agent solution.

[0003] Existing leveling agent impurity purification devices usually filter the leveling agent through a filter. After filtering for a period of time, solid matter accumulates on the stainless steel filter, which will lead to a decrease in the filtration rate and a cumbersome cleaning of these impurities, thereby reducing production efficiency to a certain extent.

[0028] Furthermore, the reset mechanism includes a plurality of slide rods 13, one end of which is slidably connected to the box body 1, and the other end of the slide rod 13 is fixedly connected to the storage box 7. A spring 14 is sleeved on the slide rod 13, and the two ends of the spring 1 are respectively in contact with the storage and the inner wall of the box body.

[0029] Furthermore, one end of the discharge pipe 8 away from the storage box 7 is flush with the lifting slot 10 .

[0030] Furthermore, a limiting mechanism for limiting the storage box 7 is provided on the box body 1 , and the limiting mechanism can fix the storage box 7 at the lower end of the inner cavity of the box body 1 after it is filled.

[0031] Furthermore, the limiting mechanism includes a limiting rod 15 fixedly connected to the collection box 5, the limiting rod includes a rod body and a spherical part, two clamping blocks 16 are slidably connected to the box body 1, and a mounting groove 17 is provided on the box body 1 for the clamping block 16 to be inserted and moved, and a spring 18 is installed in the mounting groove 17, and the two ends of the spring 18 are respectively abutted against the clamping block 16 and the inner wall of the mounting groove, and a driving rod 19 is slidably connected to the box body 1, and the two ends of the driving rod 19 are respectively inserted into the mounting grooves 17 on both sides and abut against the clamping block 16, and the ends of the driving rod 19 and the clamping block 16 abutting against each other are provided with inclined surfaces that fit each other.

[0033] Furthermore, the scrapers 6 on both sides are processed with guide slopes 22 on the sides close to each other.

[0034] Working principle: when it is necessary to purify the leveling agent with impurities, pour the leveling agent into the box 1 through the feed port 2, and the funnel will guide the leveling agent to the filter plate 4, and the filter plate 4 will filter the leveling agent. The filtered leveling agent will fall into the storage box 7. As the raw materials in the storage box 7 increase, the storage box 7 will slowly sink. In this process, the storage box 7 will drive the driven gear to rotate through the rack 11, and the driven gear will drive the bidirectional screw 9 to rotate. The bidirectional screw 9 will then drive the scrapers 6 on both sides to move along the thread tracks of their left-handed thread segments and right-handed thread segments. During the movement of the scraper 6, the impurities on the filter plate 4 will be scraped off and pushed into the collection boxes 5 on both sides for storage to prevent impurities from clogging the filter plate 4. The filter holes on the collection box 5 will allow the leveling agent that has entered by mistake to continue to flow into the storage box 7.

[0035] As the storage box 7 continues to descend, the limit rod 15 will push open the two side clamps 16 during the descent process until the spherical body on the limit rod 15 moves to the bottom of the two clamps 16. At this time, the two side clamps will gather toward the middle under the action of spring 2 18, and then the storage box 7 can be controlled to prevent position deviation by limiting the spherical body. When all the raw materials are filtered, the raw materials are discharged through the discharge pipe 8, and then the collection boxes 5 on both sides are pulled out to clean the impurities, and then the driving rod 19 is pushed inward. Under the action of the guide slope 22, the driving rod 19 can drive the two side clamps 16 to separate outward, thereby releasing the limit rod 15. At this time, the storage box 7 will rise under the action of spring 14, thereby driving the two side scrapers 6 to gather toward the middle and reset, and the end of the discharge pipe 8 away from the storage box 7 is flush with the lifting slot 10 to prevent the user from being accidentally injured during the rising process of the discharge pipe 8.

[0036] The purification device arranged in this way can automatically remove impurities on the filter plate 4 to prevent impurities from clogging the filter plate 4 and reducing the filtering efficiency. A detachable collection box 5 is also arranged on both sides of the filter plate 4 to store impurities scraped off by the scraper 6, which is convenient for cleaning the impurities. In addition, this process does not require the installation of electric drive equipment such as motors, thereby reducing energy consumption.

[0037] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
