Description

Technical Field

[0001] The utility model relates to the technical field related to glass fiber reinforced plastic products, in particular to an assembleable large-diameter glass fiber reinforced plastic washing tower. Background Art

[0002] Fiberglass scrubber towers are typically constructed by connecting pipes formed using a winding process or hand-layup tube sections. However, most existing scrubbers are monolithic structures. When using the winding process, the entire structure is already manufactured at the factory. Because the tower pipes are formed in one step, larger diameters and lengths are subject to shipping restrictions, resulting in higher costs.

[0003] Some of the existing washing towers have begun to be gradually disassembled and connected through multiple longitudinally arranged cylinders. However, during the transportation and installation process, they are still large in size, and the assembly requires the assistance of a large crane. During the installation process, it is not easy to align, and multiple workers need to make repeated adjustments. The positioning is cumbersome and the installation is inconvenient.

DETAILED DESCRIPTION

[0021] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] refer to Figure 1 A large-diameter fiberglass washing tower that can be assembled includes a cylinder 11 and a cylinder cover 12. There are several cylinders 11. In this embodiment, there are three cylinders 11. The lower end surface of the lowermost cylinder 11 is sealed to form the bottom. The uppermost cylinder 11 is connected to the cylinder cover 12, and the two cylinders 11 are detachably connected.

[0024] like Figure 3 As shown, the cylinder 11 is composed of a plurality of tube segments 111 , which are arc-shaped segments. The plurality of tube segments 111 are arranged in a circular array with the axis of the cylinder 11 as the center, thereby forming the cylinder 11 , and the tube segments 111 are detachably connected to each other.

[0025] A stop piece 116 and a limiting groove 115 are respectively provided on both sides of the circumference of the pipe segment 111, and any pipe segment 111 has the same setting, which is convenient for connecting two pipe segments 111. The stop piece 116 of one pipe segment 111 and the limiting groove 115 of the other pipe segment 111 are clamped together. When connecting, it is convenient to position and combine so that it can be guided and limited during assembly, while reducing the amount of error, which is more conducive to bolt fixation on the flange surface to form a complete cylinder 11. The joint position of the inner wall of the pipe segment is glued together by 4 layers of 300g chopped strands of mat, 6 layers of 400g glass fiber cloth and resin to ensure the strength of the connection.

[0026] like Figure 4 As shown, flanges 113 are provided on both sides of the tube segments 111 along the axial direction to facilitate the connection of the upper and lower tube segments 111. During assembly, the upper and lower tube segments 111 can be directly connected first, and then assembled into a washing tower, without having to assemble them into the cylinder 11 before connection. The combination methods are diverse and easier to assemble. Each section of the cylinder 11 is positioned by a flange designed in the form of male and female, and bolts are set and fixed at intervals of 150-200mm. The joints on the inner wall of the cylinder 11 are glued with 4 layers of 300g chopped strand mat, 6 layers of 400g glass fiber cloth and resin.

[0027] Reinforcing ribs 112 are provided on the end faces of any pipe segments 111 to ensure the strength of the pipe segments 111 themselves, thereby ensuring its stability. The reinforcing ribs 112 of any pipe segments 111 are all located at the same position. After installation, the reinforcing ribs 112 on the pipe segments 111 in the same vertical direction are in the same straight line, ensuring the combined connection and improving the strength of use. The pipe segments 111 are produced in batches, which is convenient for replacement of damage before assembly and reduces accidents.

[0028] like Figure 2 As shown, the cylinder cover 12 is connected to the uppermost cylinder body 11. In the uppermost cylinder body 11, positioning buckles 114 are provided on the end faces of several pipe segments 111. The cylinder body 11 may be provided with connectors connected to the positioning buckles 114. After the cylinder cover 12 and the cylinder body 11 are connected, they are connected and fixed by the connectors and the positioning buckles 114, which facilitates the combination to form a complete tower structure.

[0029] The cylinder cover 12 includes a plurality of tower top segments 121 , which are evenly divided. The number of the tower top segments 121 is the same as the number of the segments 111 of the single-layer cylinder 11 , which facilitates size matching.

[0030] The tower top segment 121 is wedge-shaped, and a top ring 13 is provided in the center of the cylinder cover 12, which passes through the top and bottom. The top ring 13 can form an air inlet and outlet. The top ring 13 is connected to all the tower top segments 121 during installation, which facilitates positioning and assembly and improves the connection strength. At the same time, a retaining ring 14 is provided above the tower top segment 121 to further ensure the connection strength.

[0031] Tower top segment 121 is similar to segment 111, with side flanges 124 on both sides. A retaining groove can be provided on one side for combined connection, enhancing joint strength and providing guidance and positioning during assembly. This reduces misalignment and facilitates bolting on the flange surfaces, forming a complete annular structure. The inner wall seams of the segments are bonded using four layers of 300g chopped strand mat, six layers of 400g fiberglass cloth, and resin.

[0032] The tower top fragment 121 is also provided with a top reinforcement rib 122 to ensure its own strength.

[0033] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
