Description

Technical Field

[0001] The invention relates to a glass fiber gluing device and a gluing method for manufacturing a sulfuric acid storage tank body, belonging to the technical field of processing and manufacturing equipment and methods of sulfuric acid storage tanks. Background Art

[0002] Sulfuric acid storage tanks are stationary equipment in coke oven gas purification areas. They are used to store sulfuric acid products in the sulfuric acid production process and also to store sulfuric acid supplied to the ammonium sulfate production process. During sulfuric acid storage, due to prolonged exposure to the open air and corrosion from stored sulfuric acid, the tanks need to be replaced after a period of use. The main raw materials used in the tanks are glass fiber and a bonding adhesive made from unsaturated polyester and vinyl ester. The glass fiber is then bonded layer by layer to the tank mold. The glass fiber bonding device is particularly important in the tank manufacturing process. The feeder rack and glass fiber bonding tank used for glass fiber bonding are simple in structure. After passing through the feeder rack, the glass fiber directly passes through the bonding pressure rod in the bonding tank, where it is bonded. After bonding, it is squeegeed by a squeegee before entering the next production process. This bonding device has been in use for many years, resulting in excessive and uneven bonding of the glass fiber. This not only wastes the adhesive but also affects the quality of the tank. Therefore, it is imperative to develop a device and method for uniform glass fiber distribution and bonding. Summary of the Invention

The gluing device and method can perform gluing operations on glass fibers, and the gluing is uniform. The gluing process is simple, fast and safe, and can provide reliable technical support for manufacturing sulfuric acid storage tanks at production sites, thereby ensuring the quality of the sulfuric acid storage tanks.

[0004] The technical solution to the above technical problems is:

[0005] A glass fiber glue dipping device for making sulfuric acid storage tanks, which consists of a glass fiber support high wire frame and a glass fiber glue dipping platform. The glass fiber support high wire frame includes four wire frame legs, four horizontal connecting rods, a high cross rod, a low cross rod and a plurality of wire threading iron rings.

The two ends of the high cross rod are respectively connected to the upper ends of the rear parts of the two square frames, and the two ends of the low cross rod are respectively connected to the middle of the front parts of the two square frames. A plurality of wire threading iron rings are evenly distributed along the length direction of the support rod. The glass fiber glue dipping stand includes a rectangular stand, a glue dipping pool, a glue dipping roller, a wire pressing rod, an incoming wire distribution frame, and an outgoing wire distribution frame. The glue dipping pool is placed on the rectangular stand. The roller shaft of the glue dipping roller is installed on the two side walls of the glue dipping pool.

[0007] The above-mentioned glass fiber glue dipping device for making sulfuric acid storage tanks, the said inlet distribution frame and outlet distribution frame are respectively composed of an upper horizontal bar, a middle horizontal bar, a lower horizontal bar and a separating vertical bar. The upper horizontal bar, the middle horizontal bar and the lower horizontal bar are placed horizontally and parallel in the vertical direction. The two ends of the multiple separating vertical bars pass through the middle horizontal bar and are vertically connected to the upper horizontal bar and the lower horizontal bar respectively. The multiple separating vertical bars are evenly distributed between the upper horizontal bar and the lower horizontal bar.

DETAILED DESCRIPTION

[0024] The glass fiber glue dipping device of the present invention consists of two parts: a glass fiber support wire frame and a glass fiber glue dipping stand.

[0025] Figure 1 It is shown that the fiberglass support wire frame includes four wire frame legs 1, four horizontal connecting rods 2, a high cross support rod 3, a low cross support rod 4 and multiple wire threading iron rings 5.

[0026] The four wire rack legs 1 and the four horizontal connecting rods 2 respectively form two identical parallel and opposite square frames. The two ends of the high cross support rod 3 are respectively connected to the upper end of the rear of the two square frames, and the two ends of the low cross support rod 4 are respectively connected to the middle of the front of the two square frames. A plurality of wire threading iron rings 5 are evenly installed on the high cross support rod 3 along the length direction.

[0027] Figure 1 The diagram shows that the high horizontal support rod 3 is 130-160 cm from the ground, the low horizontal support rod 4 is 20-40 cm from the ground, and 6-10 threading iron rings 5 are welded on the high horizontal support rod 3 at even intervals. The glass fiber is divided into two layers. The upper glass fiber passes through the threading iron rings 5 on the high horizontal support rod 3, and the lower glass fiber evenly passes through the low horizontal support rod 4, and then converges to the glass fiber glue table for glueing.

[0028] Figure 2 It is shown that the glass fiber glue dipping stand includes a rectangular stand 6, a glue dipping pool 7, a glue dipping roller 8, a wire pressing rod 9, a scraper 10, a glue dripping reflux trough 11, an input wire distribution rack 12, and an output wire distribution rack 13.

[0029] There are four supporting legs under the rectangular stand 6, and the glue pool 7 is placed on the rectangular stand 6. The roller shaft of the glue roller 8 is installed on the two side walls of the glue pool 7. When the glue roller 8 rotates, the glue in the glue pool 7 can be stained onto the glue roller 8.

[0030] Two pressing rods 9 are placed parallel to each other in front and behind the glue roller 8, and the two ends of the two pressing rods 9 are fixedly connected to the upper edges of the two side walls of the glue pool 7. The glass fiber passes under the two pressing rods 9 and around the upper part of the glue roller 8 for glueing.

[0031] A scraper 10 is installed between the pressure rod 9 in front of the glue roller 8 and the glue roller 8. The two ends of the scraper 10 are fixed to the two side edges of the glue pool 7. The length of the scraper 10 matches the length of the glue roller 8, and the front end of the scraper 10 is opposite to the roller surface of the glue roller 8. The glue roller 8 rotates to pick up glue from the glue pool 7. The scraper 10 scrapes off the excess glue on the glue roller and flows it into the glue pool. The glass fiber is glued from the glue roller 8 after scraping the glue. By adjusting the gap between the scraper 10 and the glue roller 8, the thickness of the glue on the glue roller 8 can be controlled to ensure the gluing effect.

[0032] The incoming distribution frame 12 and the outgoing distribution frame 13 are respectively fixed at both ends of the glue pool 7 . A glue reflux trough 11 is placed below the outgoing distribution frame 13 to collect the glue dripping from the glass fiber and return it to the glue pool 7 .

[0033] Figure 2 The incoming distribution rack 12 and the outgoing distribution rack 13 are shown to be composed of an upper horizontal bar, a middle horizontal bar, a lower horizontal bar, and vertical separator bars. The upper, middle, and lower horizontal bars are arranged horizontally and parallel to each other in the vertical direction. The ends of the multiple vertical separator bars pass through the middle horizontal bar and are vertically connected to the upper and lower horizontal bars. The multiple vertical separator bars are evenly distributed between the upper and lower horizontal bars.

[0034] The glass fiber enters the glass fiber support line frame in two layers. The upper glass fiber passes through the threading iron ring 5 on the high cross support rod 3 and enters the line-leveling hole of the upper cross bar and the middle cross bar of the glass fiber glue-in feed distribution frame 12. The lower glass fiber evenly passes through the low cross support rod 4 of the support line frame and enters the line-leveling hole between the middle cross bar and the lower cross bar of the distribution frame 12. After gathering the viscose, it enters the distribution frame 13 for uniform distribution.
