Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof and fireproof coating production, in particular to a slurry feeding structure for waterproof and fireproof coating production. Background Art
[0002] Waterproof and fire-retardant coatings are applied to the surface of materials or filled into materials to improve their waterproof and fire-retardant properties. The film layer formed after the waterproof and fire-retardant coatings are cured has certain elongation, elasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, fire prevention and protection.
[0003] Common waterproof and fire-retardant coatings, such as foaming sealants, are produced by placing a variety of raw materials into a mixing barrel for mixing and preparing a slurry. After the mixing and preparation is completed, the finished slurry is poured into a paint barrel for canning to obtain a finished waterproof and fire-retardant coating.
[0004] However, in the process of pouring the waterproof and fire-retardant coating production slurry, a common method of pouring is to pour the coating slurry directly into the coating bucket through a feeding funnel. However, during the pouring process, the slurry is prone to become congested and accumulate on the filter screen in the feeding funnel due to its thickness, resulting in slow feeding or even blockage. In addition, the particles or agglomerates in the slurry are prone to cause unsmooth slurry feeding, affecting the operational reliability of the mixing barrel during the waterproof and fire-retardant coating slurry feeding process. In addition, the existing feeding funnel is often exposed, resulting in the slurry being easily directly in contact with the air over a large area during the feeding process, and thus the slurry is prone to being contaminated or even deteriorating, affecting the later storage time of the waterproof and fire-retardant coating slurry. Utility Model Content
[0005] In view of the above-mentioned technical problems existing in the production of existing waterproof and fire-retardant coatings, the utility model provides a slurry feeding structure for producing waterproof and fire-retardant coatings.
[0006] A slurry discharge structure for producing waterproof and fire-retardant coatings comprises a stirring barrel for discharging slurry for producing waterproof and fire-retardant coatings, a discharge port being provided at one end of the stirring barrel, a discharge funnel being hingedly provided on the discharge port via a preset connecting piece, a filter being provided in the discharge funnel, and a valve being provided at one end of the discharge funnel, an isolation cover being provided on the open end of the discharge funnel, a material guide port being provided at one end of the isolation cover close to the discharge port, a servo motor being provided on the isolation cover, a rotating shaft of the servo motor being passed through a preset through hole on the isolation cover, and a stirring mechanism being provided in the rotating shaft of the servo motor inside the isolation cover, and the coating slurry filtered and retained on the surface of the filter being scraped by the stirring mechanism.
[0007] Furthermore, a partition net is arranged in the material guide port, and the mesh diameter of the partition net is larger than the mesh diameter of the filter screen.
[0008] Furthermore, the stirring mechanism includes a connecting rod, a stirring blade and a scraper. The connecting rod is fixedly connected to one end of the servo motor shaft, and the stirring blade is arranged on one end of the connecting rod.
[0009] Furthermore, a slot is provided on one side wall of the stirring blade, the installation end of the scraper is clamped in the slot on the side wall of the stirring blade, and one end of the scraper is in contact with the surface of the filter screen.
[0010] Furthermore, the covering surface of the isolation cover and the discharge funnel is set to be open, and a sealing ring is provided at the covering portion of the isolation cover and the discharge funnel.
[0011] Furthermore, the connecting part includes a hinged bar and a baffle, one end of the hinged bar is arranged in the discharge port, and the other end of the hinged bar is fixedly connected to a side wall of the discharge funnel, and the baffle is arranged on both side walls of the discharge funnel, and one end of the baffle is fixedly connected to the side wall of the hinged bar.
[0012] Furthermore, a screw is threadedly connected to one side wall of the baffle, and the tail end of the screw is threadedly connected to a screw hole preset on the wall of the isolation cover ring.
[0013] Beneficial effects of the utility model:
[0014] 1. The finished waterproof and fire-retardant coating slurry is poured out from the mixing barrel, and then poured into the discharge funnel along the discharge port at the hinged strip, and blocked by the baffle to prevent slurry leakage, so that the slurry is introduced through the guide port of the isolation cover, and preliminarily filtered through the partition net, so as to filter out large particles of impurities in the slurry, and then the slurry introduced into the discharge funnel is filtered through the filter net for the second time, so as to filter out small particles of impurities or agglomerates, and then the connecting rod is driven to rotate by the servo motor shaft, so that the stirring blade rotates accordingly, so as to stir the slurry deposited on the upper layer of the filter net, stir the slurry to make it thin, facilitate filtering and discharge, and prevent the slurry from being blocked, and then drive the scraper to rotate, and the scraper is abutted against the surface of the filter net, so as to squeeze and disperse the agglomerates filtered on the filter net, so that the slurry is discharged smoothly and the filter net is blocked, thereby improving the operation reliability of the mixing barrel in the process of discharging the waterproof and fire-retardant coating slurry.
[0015] 2. By setting the isolation cover on the discharge funnel and fixing the working position of the isolation cover through screw threads installed in conjunction with the baffle, it is convenient for the later installation and disassembly of the isolation cover. At the same time, the sealing ring is abutted against the connection between the isolation cover and the discharge funnel to improve the sealing of the connection between the two. Then, the isolation cover is set on the open end of the discharge funnel to reduce the contact area between the paint slurry and the air during the discharge process, thereby reducing the possibility of the slurry being contaminated or even deteriorated, and extending the later storage time of the waterproof and fire-retardant paint slurry.
