Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a steel pipe internal spraying equipment based on polyurethane insulation technology. Background Technology

[0002] The application of polyurethane insulation technology to steel pipe insulation is based on the excellent properties of polyurethane material. Polyurethane is a polymer material that is mainly produced by the polymerization reaction of isocyanate and polyol under the action of a catalyst. In steel pipe insulation, after the polyurethane raw materials are mixed, they are applied to the surface of the steel pipe by pouring or spraying. When the polyurethane foams and cures on the surface of the steel pipe, it forms a tight insulation layer.

[0003] Currently, when applying polyurethane insulation to steel pipes, the steel pipes need to be cleaned and pre-treated to ensure the cleanliness of the pipe surface. Based on the insulation requirements, polyurethane raw materials such as isocyanate and polyols need to be accurately weighed. During the mixing process, appropriate amounts of catalysts, foaming agents, and other additives need to be added, and the mixture must be thoroughly mixed at a suitable temperature and stirring speed to ensure uniform reaction. The mixed polyurethane raw materials are then injected into molds pre-set around the steel pipe using a pouring device. A spraying device is then used to directly spray the raw materials onto the steel pipe surface. While existing equipment is convenient for spraying the surface of the steel pipe, it is not convenient for spraying the interior of the steel pipe according to insulation requirements, resulting in significant limitations during the spraying process.

[0036] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0037] like Figures 1-4As shown, this embodiment proposes a steel pipe internal spraying device based on polyurethane insulation technology, including a spraying plate 1, a placement seat 2, anti-fall components, a spraying box 3, a pushing seat, an outer spraying ring 4, an inner spraying ring 5, and spraying components. The placement seat 2 is fixedly connected to the top of the spraying plate 1, and an anti-slip pad 15 is fixedly connected to the top of the placement seat 2. The anti-slip pad 15 has a placement groove for placing steel pipes, which facilitates the stable placement of steel pipes of different specifications. Two anti-fall components are provided, which are respectively set on both sides of the placement seat 2. The spraying box 3 is slidably set on the placement seat 1. On one side of seat 2, a push seat is set between spray box 3 and spray plate 1. Spray outer ring 4 is set on one side of spray box 3. Spray inner ring 5 is located inside spray outer ring 4. Multiple spray nozzles are opened on both spray outer ring 4 and spray inner ring 5 to facilitate all-round spraying of polyurethane for insulation on the outside and inside of steel pipe. Spray assembly is set between spray outer ring 4 and spray inner ring 5. A feed port is opened at the top of spray box 3. A box cover 14 is detachably installed at the feed port. Opening the box cover 14 on spray box 3 allows the mixed polyurethane raw material to enter spray box 3.

[0038] Specifically, the spraying assembly includes a delivery pump 6, a connector 7, and a connecting pipe 8. The delivery pump 6 is installed on the outer wall of the spraying box 3. The input end of the delivery pump 6 is connected to the spraying box 3 and extends into the inner bottom of the spraying box 3. The connector 7 is located on one side of the spraying box 3. Multiple connecting rods 16 are fixedly connected between the connector 7 and the spraying box 3 to provide stable support for the connector 7. The output end of the delivery pump 6 is connected to the connector 7. Multiple connecting pipes 8 are provided, and the multiple connecting pipes 8 are fixedly connected between the connector 7 and the outer spraying ring 4 and the inner spraying ring 5, respectively.

[0039] When the delivery pump 6 is started, the polyurethane raw material mixed in the spray box 3 can enter the outer spray ring 4 and the inner spray ring 5 through the connector 7 and multiple connecting pipes 8 respectively. This allows the outer spray ring 4 and the inner spray ring 5 to spray polyurethane raw material all over the outside and inside of the steel pipe through multiple spray nozzles, thereby improving the spraying effect on the steel pipe.

[0040] Specifically, the anti-fall component includes a support frame 9, a damping spring 10, and an anti-fall plate 11. The support frame 9 is fixedly connected to the top of the spray plate 1. There are two damping springs 10, which are symmetrically installed on the support frame 9. The anti-fall plate 11 is fixedly connected between the two damping springs 10, and the anti-fall plate 11 has a groove that matches the steel pipe.

[0041] When the steel pipe is placed on the placement seat 2, the damping spring 10 will apply force to the anti-fall plate 11, so that the anti-fall plate 11 makes stable contact with the steel pipe through the groove. This allows the two anti-fall plates 11 to stably clamp and position steel pipes of different specifications, thereby improving the stability of placing and spraying steel pipes of different specifications.

[0042] Specifically, the push base includes a mounting frame 12 and an electric cylinder 13. The mounting frame 12 is fixedly connected to the top of the spray plate 1, and the electric cylinder 13 is installed on the top of the mounting frame 12. The output end of the electric cylinder 13 is fixedly connected to the spray box 3. Two sliding blocks are symmetrically connected to the bottom of the spray box 3. The spray plate 1 is provided with a sliding groove for the sliding blocks to slide.

[0043] When the electric cylinder 13 is started, it pushes the spray box 3, which can move the spray box 3 on the spray plate 1 through two sliding blocks. This allows the delivery pump 6, connector 7, connecting pipe 8, outer spray ring 4, and inner spray ring 5 to move, thereby enabling the outer spray ring 4 and inner spray ring 5 to spray the outside and inside of the steel pipe in all directions.

[0044] In this embodiment, the mixed polyurethane raw material is first fed into the spraying box 3 through the inlet, and the steel pipe to be sprayed is placed on the placement seat 2. The two anti-fall plates 11 stably clamp and position the steel pipe. Then, the electric cylinder 13 is started, which pushes the spraying box 3, causing the spraying box 3 to drive the delivery pump 6, connector 7, connecting pipe 8, outer spraying ring 4 and inner spraying ring 5 to gradually approach the steel pipe. At the same time, the delivery pump 6 is started, so that the polyurethane raw material in the spraying box 3 enters the outer spraying ring 4 and inner spraying ring 5 through the connector 7 and multiple connecting pipes 8 respectively, thereby enabling all-round spraying of the outside and inside of the steel pipe.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
