Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic coating equipment, in particular to a plastic coating steel pipe material recovery device. Background Art
[0002] There is a steel pipe plastic coating technology that places the heated steel pipe on a roller shaft, and drives the steel pipe to rotate by the rotation of the roller shaft. At the same time, hot-melt material is evenly spread on the top of the steel pipe, and the material falls on the steel pipe and melts when it encounters heat, forming a uniformly thick plastic coating layer on the surface of the steel pipe.
[0003] In the prior art, when spreading materials, as the steel pipe rotates, some materials will fall from the steel pipe, which will not only cause waste, but also the dust in the materials will float around and easily pollute the workshop environment and affect the health of employees. If the spraying is maintained for a long time, as the dust concentration in the air increases, there is also a risk of dust explosion. Utility Model Content

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0017] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0018] Example 1, please refer to Figure 1As shown, in the embodiment of the utility model, a plastic coated steel pipe material recovery device comprises a box body 1, a feed part 2 is provided on the top of the box body 1, and the feed part 2 is connected to the box body 1; a magnet screen 3 is arranged horizontally inside the box body 1, and the magnet screen 3 is arranged inside the box body 1, below the feed part 2. The device is placed just below the steel pipe to be coated with plastic. During coating, the material will fall into the feed part 2, and enter the connected box body 1 along the feed part 2, and fall through the magnet screen 3 in the box body 1, and the iron filings mixed in the material will be adsorbed by the magnet screen 3, thereby realizing filtering and recovery.
[0019] Example 2, please refer to Figure 1 , Figure 2 As shown, compared with Example 1, the difference is that the two ends of the magnet screen 3 are connected with a flip handle 301, and the flip handle 301 passes through the box body 1 and is located outside the box body 1. By turning the flip handle, the magnet screen 3 connected thereto can be driven to flip. When the plastic-coated material is recycled for a long time, the residual material on the magnet screen 3 accumulates and blocks the mesh, by flipping the magnet screen 3, the residual material on the magnet screen 3 can fall off under the influence of gravity and the vibration caused by the flipping, so as to prevent the magnet screen 3 from being blocked; the connection between the flip handle 301 and the magnet screen 3 is a movably connected connection through screws, and the flip handle 301 can be removed after loosening the screws. After removing the flip handles 301 at both ends, the magnet filter 3 can be taken out. When the recycling work is maintained for a long time, when too much iron filings accumulate on the magnet filter 3 and affect the passage of materials, the magnet filter 3 can be taken out for cleaning.
[0020] Furthermore, a movable buckle 302 is provided on the box body 1 next to the flip handle 301. When flipping is not required, the flip handle 301 can be buckled by the movable buckle 302, thereby restricting the magnetic screen 3 connected thereto so that it will not be affected and flip automatically when the material falls.
[0021] Example 3, please refer to Figure 1 , Figure 2 As shown, compared with the above embodiment, an air inlet 402 is respectively provided below the two ends of the magnet screen 3, and the air inlet 402 connects the inside and outside of the box 1. The air inlet 402 is connected to one end of the air inlet pipe 401 outside the box 1, and the other end of the air inlet pipe 401 is connected to the air extractor 4. A support frame 6 is provided below the air extractor 4. The position of the air extractor 4 is adjusted according to the position of the steel pipe to be coated with plastic, and the air inlet is aligned with the steel pipe to be coated with plastic, and then placed in the support frame 6 for fixing. The free plastic-coated dust in the air can be extracted by the air extractor 4 and sent into the inside of the box 1 through the air inlet pipe 401.
[0022] Example 4, please refer to Figure 1As shown, a discharge ramp 101 is provided at the bottom of the box body 1, and the discharge ramp 101 is located below the air inlet 402. The bottom of the discharge ramp 101 is connected to the discharge port 5, and the discharge port 5 is connected to the inside and outside of the box body 1. The material filtered by the magnetic screen will fall on the discharge ramp 101 and slide down along the discharge ramp 101 into the recovery bag; the two discharge ramps 101 are respectively arranged below the two air inlets 402, and the two air inlets 402 are respectively aligned with the two discharge ramps 101. The plastic-coated dust sucked in by the external vacuum pump 4 will fall on the discharge ramp 101, and under the action of the airflow generated during the inhalation, it will slide down along the discharge ramp 101 into the external recovery bag together with the material remaining on the discharge ramp 101.
[0023] For further information, see Figure 1 , Figure 2 As shown, a discharge port 5 is provided on the bottom surface of the box body 1, and the bottoms of the two discharge ramps 101 are connected to the discharge port 5, and the discharge port 5 is connected to the inside and outside of the box body 1. The plastic-coated material and dust will slide down the discharge ramp 101 and enter the external recycling bag from the discharge port 5.
[0024] Example 6, please refer to Figure 1 As shown, the bottom surface of the box body 1 is provided with a telescopic support leg 102. According to the height of the steel pipe to be plastic coated, the height of the box body 1 is adjusted by extending and retracting the telescopic support leg 102, so that the feed part 2 of the box body 1 is as close to the steel pipe to be plastic coated as possible, and then the screws on the telescopic support leg 102 are tightened to fix it, so as to catch the fallen plastic coated material to the maximum extent.
[0025] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
