Description

Technical Field

[0001] This utility model relates to the field of steel pipe cleaning technology, specifically to a device for cleaning dust from the surface of steel pipes. Background Technology

[0002] Dust, oil, and soluble salts (such as chlorides and sulfides) on the surface of steel can form a barrier layer, hindering the chemical bonding between the coating and the metal substrate. Therefore, steel pipes need to be cleaned before coating. Currently, steel pipe cleaning mainly includes physical or chemical-mechanical combined processes. For non-high-precision coatings (such as epoxy powder), physical cleaning is generally sufficient to meet the requirements. Most physical cleaning devices are currently modular, requiring the steel pipe to pass through multiple independent mechanisms and be transported, resulting in a large footprint and numerous cleaning steps. Therefore, this invention proposes a steel pipe dust surface cleaning device. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A steel pipe dust surface cleaning device includes a frame and a cleaning mechanism, a sweeping mechanism and a dust removal mechanism arranged on the frame along the steel pipe's travel path. The cleaning mechanism is used to clean substances adhering to the surface of the steel pipe, the sweeping mechanism is used to brush the surface of the steel pipe, and the dust removal mechanism is used to blow air onto the surface of the steel pipe.

[0005] Furthermore, the cleaning mechanism includes two rotating shafts arranged parallel to each other vertically. The rotating shafts are rotatably mounted on the frame. Cleaning rollers are mounted on the rotating shafts. The two cleaning rollers form a channel for the steel pipe to pass through. Gears are mounted on the rotating shafts. The two gears mesh with each other. A first drive motor is mounted on the frame. The output shaft of the first drive motor is connected to one of the rotating shafts.

[0006] Furthermore, the cleaning mechanism includes a positioning frame mounted on a frame via a bracket, a cleaning ring coaxial with the channel is rotatably mounted inside the positioning frame, and cleaning bristles are arranged in a ring array on the inner side of the cleaning ring.

[0007] Furthermore, a positioning ring groove is constructed on the outer periphery of the cleaning ring, and at least three positioning wheels are installed in the positioning frame.

[0009] Furthermore, the dust removal mechanism includes a ventilation duct mounted on a frame, and multiple nozzles are mounted in a circular array on the ventilation duct.

[0010] Furthermore, the nozzle's air outlet is tilted towards the steel pipe, so that when the nozzle sprays air onto the steel pipe, it carries dust and moves it away from the steel pipe.

[0011] Furthermore, a support roller is rotatably mounted on the frame.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0015] like Figures 1-4As shown in the figure, an embodiment of the present invention provides a steel pipe dust surface cleaning device, including a frame 1 and a cleaning mechanism 2, a sweeping mechanism 3, and a dust removal mechanism 4 arranged on the frame 1 along the steel pipe's travel path. The cleaning mechanism 2 is used to clean the substances adhering to the steel pipe surface, the sweeping mechanism 3 is used to brush the steel pipe surface, and the dust removal mechanism 4 is used to blow air onto the steel pipe surface. The cleaning mechanism 2, sweeping mechanism 3, and dust removal mechanism 4 are arranged according to the steel pipe's travel path and are all installed on the frame 1. When cleaning the steel pipe, the cleaning mechanism 2 first removes the insulating material from the steel pipe surface. The steel pipe is treated with an anchor pattern to improve the adhesion of the coating during subsequent painting. Then, the surface cleaned by the cleaning mechanism 2 is brushed by the cleaning mechanism 3. The main purpose is to remove residual dust, abrasive and loose particles. Finally, the surface of the steel pipe is treated with compressed air by the dust removal mechanism 4 to complete the final dust removal work. It should be noted that the above-disclosed structures should be installed in a sealed housing and used together with a dust removal mechanism. The use of a sealed housing and a dust removal mechanism is a common technical means used by those skilled in the art, so it is not disclosed. As can be seen from the above-disclosed content, this utility model integrates the mechanisms required for each step of steel pipe cleaning, reducing the size of the device. It also processes the steel pipes step by step, including removing surface impurities, brushing, and spraying, thereby improving the cleaning effect and simplifying the entire steel pipe cleaning process, which is beneficial for completing the steel pipe cleaning work.

[0016] like Figures 1-4 As shown, in some embodiments, the cleaning mechanism 2 includes two vertically parallel rotating shafts 201, which are rotatably mounted on the frame 1. Cleaning rollers 202 are mounted on the rotating shafts 201, and the two cleaning rollers 202 form a channel for the steel pipe to pass through. Gears 203 are mounted on the rotating shafts 201, and the two gears 203 mesh with each other. A first drive motor 204 is mounted on the frame 1, and the output shaft of the first drive motor 204 is connected to one of the rotating shafts 201 through a coupling. During the rotation of the rotating shaft 201 by the first drive motor 204, the two cleaning rollers 202 will rotate synchronously due to the meshing of the two gears 203. However, the two cleaning rollers 202 rotate in opposite directions. As the cleaning rollers 202 rotate, they contact the steel pipe, breaking the oxide layer on the surface of the steel pipe, thereby causing the oxide layer to fall off. At the same time, anchor patterns are formed on the surface of the steel pipe. The channel enclosed by the two cleaning rollers 202 can fully contact the outer periphery of the steel pipe.

[0017] like Figures 1-4As shown, in some embodiments, the cleaning mechanism 3 includes a positioning frame 301 mounted on the frame 1 via a bracket 306. A cleaning ring 303 coaxial with the channel is rotatably mounted inside the positioning frame 301. Cleaning bristles 304 are arranged in a ring array on the inner side of the cleaning ring 303. The cleaning bristles 304 are made of nylon. The continuously rotating cleaning ring 303 brushes the steel pipe after it has been treated by the cleaning roller 202, brushing off the damaged oxide layer from the steel pipe, thus performing a second cleaning step on the steel pipe.

[0018] like Figures 1-4 As shown, in some embodiments, the outer periphery of the sweeping ring 303 is provided with a positioning ring groove, and at least three positioning wheels 302 are installed in the positioning frame 301. The positioning wheels 302 are located in the positioning ring groove and are in rolling connection with the positioning ring groove. Due to the cooperation between the positioning ring groove and the positioning wheels 302, the sweeping ring 303 can only perform circular motion, and the three positioning wheels 302 form a support and limit for the sweeping ring 303. During the rotation of the sweeping ring 303, the positioning wheels 302 also rotate to reduce friction. Of course, bearings can also be used to install the sweeping ring 303 on the positioning frame 301.

[0019] like Figures 1-4 As shown, in some embodiments, a second drive motor 307 is installed on the frame 1. The second drive motor 307 is connected to the cleaning ring 303 via a pulley structure 305. The pulley mechanism includes two pulleys and a transmission belt. The two pulleys are respectively installed on the output shaft of the cleaning ring 303 and the second drive motor 307. The transmission belt is sleeved on the two pulleys. With the cooperation of the pulley structure 305, the second drive motor 307 can smoothly drive the cleaning ring 303 to rotate, thereby completing the cleaning action on the steel pipe through the cleaning bristles 304.

[0020] like Figures 1-4 As shown, in some embodiments, the dust removal mechanism 4 includes a ventilation pipe 401 mounted on the frame 1. Multiple nozzles 402 are mounted in a circular array on the ventilation pipe 401. The air outlets of the nozzles 402 are inclined towards the steel pipe. When the air from the nozzles 402 sprays onto the steel pipe, it carries the dust away from the steel pipe. The ventilation pipe 401 has a connector for connecting a compressed air source through a hose. The air source enters the ventilation pipe 401 through the hose and is then sprayed out through the nozzles 402. The compressed air blows directly onto the surface of the steel pipe and carries the dust towards the cleaning mechanism 3, thereby completing the third step of cleaning the steel pipe.

[0021] like Figures 1-4 As shown, in some embodiments, a support roller 5 is rotatably mounted on the frame 1. The purpose of the support roller 5 is to support the steel pipe throughout the device, thereby keeping the steel pipe in a horizontal state and maintaining stability.

[0022] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
