Description

Technical Field

[0001] This utility model relates to the field of fiberglass grating production technology, specifically to a rapid curing device for fiberglass grating sand-filled layers. Background Technology

[0002] Fiberglass grating, also known as glass fiber reinforced plastic grating, is made by compounding and assembling resin as the matrix material and glass fiber as the reinforcing material through a specific molding process. Based on the different matrix materials (resins) used, it is classified into isophthalic acid grating, vinyl ester grating, and phenolic acid grating, etc.; based on the different molding methods, it is further classified into molded fiberglass grating and pultruded fiberglass grating. Molded fiberglass grating is made by interlacing glass fibers and casting resin into a single piece, exhibiting excellent corrosion resistance; pultruded grating is made by continuously impregnating fibers with resin, pultruding and heating to cure, continuously molding, and then assembling, resulting in higher strength.

[0003] For example, patent application number 201710336989.7 discloses a method for producing fiberglass grating with a sand-filled layer. This invention discloses a method for producing fiberglass grating with a sand-filled layer, including the following steps: mold preparation, matrix material preparation, fiberglass grating layering, setting a sand-filled reinforcing protective layer, applying an outer protective layer, curing, and finishing to form a fiberglass grating with a sand-filled layer. This invention has a complete and reasonable formula, low cost, and produces products with high strength, meeting customer needs, greatly enhanced internal and external bonding, and good corrosion resistance, wear resistance, and good toughness and elasticity. However, this method for producing fiberglass grating with a sand-filled layer does not use a dedicated device for curing the sand-filled layer.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a rapid curing device for fiberglass grating with sand sandwich layer. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-2 As shown, a rapid curing device for fiberglass grating with sand-filled layer includes a drying oven body 1. A support frame 101 is provided on the rear end surface of the drying oven body 1, and a telescopic cylinder 102 is fixedly installed through the front upper surface of the support frame 101. The advantage of this arrangement is that the telescopic cylinder 102 can push the sealing plate 103 to fit against the upper surface of the drying oven body 1 for sealing.

[0022] Furthermore, a sealing plate 103 is provided on the lower end surface of the telescopic cylinder 102, and a hot air pipe 104 is provided on the upper end surface of the sealing plate 103. An air outlet pipe 2 is provided on one side surface of the drying chamber body 1, and an exhaust fan 201 is installed on the inner surface of the air outlet pipe 2. The advantage of this arrangement is that, through the setting of the hot air pipe 104, the interior of the drying chamber body 1 can be heated after the sealing plate 103 is closed with the drying chamber body 1, and the internal fiberglass grating can be dried and heated to accelerate the curing of the sand-filled layer. At the same time, the hot and cold air discharged through the air outlet pipe 2 is filtered by the air filter element 204 before being discharged, avoiding the leakage of toxic air and causing air pollution.

[0023] Furthermore, a connecting ring 202 is provided on the front end surface of the air outlet duct 2, and a connecting shell 203 is spirally installed on the outer surface of the connecting ring 202. A rotating block 205 is provided on the outer surface of the connecting shell 203, and an air filter element 204 is installed on the inner wall surface of the connecting shell 203. The advantage of this arrangement is that the air filter element 204 can filter the blown air, and the air filter element 204 can be removed and replaced periodically through the connecting ring 202.

[0024] like Figures 3-4 As shown, a placement plate 3 is provided on the inner surface of the drying oven body 1, and support blocks 308 are provided on both sides of the upper surface of the placement plate 3. Support block 301 is provided in the middle of the upper surface of the placement plate 3, and telescopic cylinder 302 is provided on the upper surface of support block 301. The advantage of this arrangement is that, through the telescopic cylinder 302, the push plate 303 can be moved to make the contact plate 305 contact with different types of fiberglass gratings, clamp and fix them, and improve the adaptability of the device.

[0025] Furthermore, the front end surface of the telescopic cylinder 302 is provided with a push plate 303, and the rear end surface of the push plate 303 is provided with limit slide rods 304 on both sides. The limit slide rods 304 and the support block 308 are slidably connected. The advantage of this setting is that the pushing direction of the push plate 303 can be restricted by the limit slide rods 304, so as to avoid deviation when it comes into contact with the fiberglass grating.

[0026] Furthermore, a limiting slide rail 306 is slidably mounted through the front end surface of the push plate 303, and a contact plate 305 is provided on the front end surface of the limiting slide rail 306. A compression spring 307 is provided on the rear end outer surface of the limiting slide rail 306, and the compression spring 307 is fixedly connected to the push plate 303. The advantage of this arrangement is that by setting the compression spring 307, the compression of the fiberglass grating can be reduced, thus protecting it.

[0027] Working Principle: When using this fiberglass grating sand-filled layer rapid curing device, firstly, the fiberglass grating with pre-coated material is placed on the placement plate 3 installed on the inner surface of the drying chamber body 1. Then, the telescopic cylinder 302 is activated to push the push plate 303 inward, so that the contact plate 305 contacts the surface of the fiberglass grating. After the contact plate 305 presses backward to compress the spring 307, making the fit between the contact plate 305 and the fiberglass grating tighter. After fixing, the telescopic cylinder 102 on the upper surface of the support frame 101 is activated to move the sealing plate 103 downward until it is in contact with the upper surface of the drying chamber body 1 and the seal is completed. Then, hot air blown out through the hot air pipe 104 heats the inside of the drying chamber body 1, drying and heating the fiberglass grating inside, accelerating the curing of the sand-filled layer. At the same time, the exhaust fan 201 installed on the inner surface of the air outlet pipe 2 filters the air inside the drying chamber body 1 through the air filter element 204 and then discharges it. This is the working principle of the fiberglass grating sand-filled layer rapid curing device.
