Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically to an impurity filtration device for fireproof and heat-insulating coatings. Background Technology

[0002] Coatings are liquid or solid materials that are applied to the surface of an object to form a protective, decorative, or special-function film (such as corrosion resistance, fire resistance, and heat insulation). They are mainly composed of film-forming substances (such as resins and oils), pigments, solvents, and additives. They are applied to the surface of a substrate through processes such as brushing, spraying, and roller coating, and after drying, they form a uniform and continuous thin film. Fire-retardant and heat-insulating coatings have special properties, and their core function is to delay the spread of fire and block heat transfer.

[0003] During the production process of fireproof and heat-insulating coatings, some particulate impurities often exist in the raw materials. The presence of these impurities will affect the quality and performance of the coating, so it is necessary to use an impurity filtration device to filter them.

[0004] Currently, most common paint impurity filtration devices adopt a single-stage filtration structure, relying solely on a single filter screen to filter the paint. This method cannot perform stratified filtration of impurities of different particle sizes in the paint, resulting in poor filtration efficiency and difficulty in effectively removing impurities of various sizes from the paint, thus affecting the product quality of fireproof and heat-insulating coatings. In addition, existing filtration devices have shortcomings in paint feeding design, which can easily lead to uneven feeding when the paint enters the filtration device. Excessive paint flow in some areas not only increases the load on the filter screen but may also cause impurities to accumulate locally on the filter screen, reducing filtration efficiency and affecting the overall filtration effect. Moreover, the existing device structure is relatively fixed, which is quite inconvenient in terms of impurity cleaning. When the filter screen is clogged with impurities, the cleaning process often requires a lot of time and effort to disassemble the device, which increases labor costs and reduces production efficiency, making it difficult to meet the needs of continuous and high-efficiency production.

[0005] Therefore, it is necessary to propose an impurity filtration device for fireproof and heat-insulating coatings. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an impurity filtration device for fireproof and heat-insulating coatings. This device is capable of uniformly distributing the coating, achieving multi-stage filtration, and is easy to clean. It solves the problems existing in the prior art, improves the production quality and efficiency of coatings, and resolves the issues raised in the background art.

[0007] This utility model provides the following technical solution: a device for filtering impurities in fireproof and heat-insulating coatings, comprising a filter box and a bottom frame:

[0008] The bottom of the filter box is provided with a bottom frame, and three sets of sliding grooves are provided on the side of the filter box;

[0009] Filter plates are inserted into the interior of the three sets of chutes. A feeding frame is fixedly connected to the upper side of the filter box. A feeding pipe is fixedly connected to the outside of the feeding frame. Four sets of triangular dividing plates are fixedly connected inside the feeding frame. The four sets of triangular dividing plates are arranged in a square at equal intervals.

[0010] Preferably, the three sets of filter plates have different sizes of filter holes, and the three sets of filter plates are arranged from top to bottom in descending order of filter hole size, and the three sets of filter plates are inclined at 30°.

[0011] Preferably, the lower end of the filter box is provided with a slot, the upper end of the bottom frame is fixedly connected with a plug, the plug is inserted into the interior of the slot, and the lower end of the bottom frame is fixedly connected with a discharge pipe.

[0012] Preferably, side blocks are fixedly connected to both sides of the lower end of the filter box, and connecting grooves are provided on both sides of the side blocks. Side blocks are fixedly connected to both sides of the upper end of the bottom frame, and insert rods are fixedly connected to both sides of the upper surface of the side blocks.

[0013] Preferably, the insert rod is inserted into the interior of the connecting groove, and a nut is threaded onto the outer surface of the upper end of the insert rod, with the lower surface of the nut fitting against the upper surface of the side block.

[0014] Preferably, the upper end of the filter box is provided with a second slot, and a top cover is inserted into the second slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This fire-retardant and heat-insulating coating impurity removal device uses three sets of filter plates, arranged with filter holes from largest to smallest and from top to bottom, inserted into the chute during impurity filtration. The coating is fed into the feed frame through the feed pipe, where it is evenly distributed in a square arrangement and falls into the filter box, passing sequentially through the three sets of filter plates at a 30° angle. Due to the filter holes being arranged from largest to smallest, multi-stage filtration is achieved. The filtered impurities can be cleaned by removing the filter plates, opening the top cover, and disassembling the bottom frame. This structure effectively distributes the incoming coating evenly, preventing any impact on the filtration effect. Combined with multi-stage filtration of the fire-retardant and heat-insulating coating, it effectively removes impurities of various sizes from the coating, improving the filtration effect and quality. The device is also detachable, facilitating cleaning and ensuring effective impurity filtration. Attached Figure Description
