Abstract
Description
Technical Field
[0001] This utility model relates to the field of recycling device technology, specifically to a steel pipe spray powder recycling device. Background Technology
[0002] When applying anti-corrosion powder to steel pipes, some floating powder is generated. On the one hand, this powder will cause pollution in the surrounding environment; on the other hand, it will also be a waste if it is not recycled.
[0003] These powders are recovered using a steel pipe spraying powder recovery device.
[0004] The steel pipe spray powder recovery device includes a frame with a recovery container connected to the recovery pipe. A suction fan is installed in the middle of the recovery pipe, and the powder sucked up by the recovery pipe falls into the container, thus completing the absorption of powder peony.
[0005] In the existing technology, the steel pipe spraying powder recovery device directly recovers the powder, that is, no other measures are taken for the recovery of the powder. Because the solvent in the powder evaporates quickly, the powder is prone to deterioration, which affects the reuse of the powder. Summary of the Invention
[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a steel pipe spraying powder recycling device that reduces powder deterioration and facilitates powder reuse.
[0007] The technical solution of this utility model is implemented as follows: a steel pipe spray powder recovery device, including a frame, a recovery container connected to a recovery pipe on the frame, and a suction fan installed in the middle of the recovery pipe. Its features include: a humidification chamber, a grinding chamber, and a solvent tank. The solvent tank is connected to multiple nozzles via pipes. The multiple nozzles are arranged downwards inside the humidification chamber. The humidification chamber has a humidification chamber inlet and a humidification chamber outlet, which can humidify the materials entering it. The grinding chamber has a grinding chamber inlet and a grinding chamber outlet, which can grind the materials entering it. The recovery pipe also leads to the humidification chamber inlet, the humidification chamber outlet connects to the grinding chamber inlet, and the grinding chamber outlet connects to the recovery container.
[0008] Furthermore, two grinding discs are installed in the grinding chamber. These two grinding discs are a fixed grinding disc and a rotating grinding disc, respectively. A rotating motor is connected to the rotating grinding disc. The grinding discs have material leakage holes that run vertically through them. The material leakage holes on the fixed grinding disc are fixed material leakage holes, and the material leakage holes on the rotating grinding disc are rotating material leakage holes. The fixed grinding disc is in contact with the rotating grinding disc from the bottom and can grind the material. The fixed material leakage holes and the rotating material leakage holes are not vertically aligned.
[0009] Furthermore, the recycling container has a horizontally arranged partition in the middle, and a reflux pipe connecting the bottom of the recycling container to the solvent tank, with a reflux pump installed in the middle of the reflux pipe.
[0010] The beneficial effects of this utility model are: such a steel pipe spraying powder recycling device has the advantages of reducing powder deterioration and facilitating reuse. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0014] like Figure 1 As shown, a steel pipe spraying powder recovery device includes a frame 1, a recovery container 3 connected to a recovery pipe 2 on the frame, and a suction fan 4 installed in the middle of the recovery pipe. It is characterized by further including a humidifying chamber 5, a grinding chamber 6, and a solvent tank 7. The solvent tank is connected to multiple nozzles 51 by pipes. The multiple nozzles are arranged downwards inside the humidifying chamber. The humidifying chamber has a humidifying chamber inlet 52 and a humidifying chamber outlet 53, which can humidify the materials entering it. The grinding chamber has a grinding chamber inlet 61 and a grinding chamber outlet 62, which can grind the materials entering it. The recovery pipe leads to the humidifying chamber inlet, the humidifying chamber outlet connects to the grinding chamber inlet, and the grinding chamber outlet connects to the recovery container.
[0015] The above-described features of this invention allow for the initial spraying of a solvent, such as ethanol, with the powder during recycling to keep it moist and reduce deterioration. The powder is then pulverized and finally recycled, facilitating reuse and achieving the intended purpose of this invention.

[0017] Furthermore, two grinding discs are installed in the grinding chamber. These two grinding discs are a fixed grinding disc 63 and a rotating grinding disc 64. A rotating motor 66 is connected to the rotating grinding disc. Each grinding disc has a material leakage hole 65 that runs vertically through it. The material leakage hole on the fixed grinding disc is a fixed material leakage hole 651, and the material leakage hole on the rotating grinding disc is a rotating material leakage hole 652. The fixed grinding disc is in contact with the bottom of the rotating grinding disc and can grind the material. The fixed material leakage hole and the rotating material leakage hole are not vertically aligned.
