Description

Technical Field

[0001] This utility model relates to the field of steel structure spraying technology, and in particular to an environmentally friendly spraying device for steel structure production. Background Technology

[0002] I-beams are commonly used steel structural components in construction engineering. Their cross-sectional shape is I-shaped, offering advantages such as light weight and high strength. Currently, during the processing of I-beams, rust prevention coatings are applied to their surfaces to prevent rust. Most existing steel structure coating equipment uses mechanical pressurized spraying, requiring multiple operators to perform the rolling spraying operation, increasing labor costs and reducing work efficiency. Furthermore, the harmful gases produced by the coatings can easily pollute the surrounding air, failing to meet the environmental protection and energy-saving requirements of steel structure coating equipment.

[0003] Publication No.: CN221016915U An environmentally friendly spraying device for producing steel structural components includes a conveying section, a spraying section, and a drying section. Guide rollers for restricting the movement of I-beams are rotatably installed at the two opposing ends of two connecting seats. Vertical pipes extend to both sides of the I-beams, and multiple spray nozzles for painting are installed at the bottom of each vertical pipe. Through the conveying and spraying sections, multiple electric rollers lift the I-beams and drive them to move horizontally. The guide rollers on both sides simultaneously press against the sides of the I-beams. Under the restriction of the guide rollers, the I-beams are unlikely to deviate, ensuring stable horizontal movement and facilitating stable spraying by the spray nozzles on both sides. Through the drying section, multiple drying lamps on both sides dry the sprayed I-beams, improving the drying speed of the paint and increasing processing efficiency.

[0004] For large steel structures, open-type spraying equipment is commonly used. The paint inside this equipment directly escapes to the outside, easily causing air pollution and potentially harming the human body if inhaled. Therefore, there is a need to propose an environmentally friendly spraying device for steel structure production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where paint inside the device directly escapes to the outside, easily causing air pollution and harming the human body when inhaled. Therefore, this invention proposes an environmentally friendly spraying device manufactured with a steel structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly spraying device for steel structure production includes a processing platform with an I-beam above it. A fixed mounting frame is fixedly installed at the top of the processing platform, and a spraying mechanism is installed at the top of the fixed mounting frame. A purification mechanism is also installed at the top of the fixed mounting frame. The purification mechanism includes a pair of interconnected suction hoods that are fixedly inserted through the fixed mounting frame. An air pump is fixedly installed at the top of the fixed mounting frame, and a purification box is fixedly installed at the top of the fixed mounting frame.

The other end of the air extraction pipe is connected to the suction hoods, and the other end of the air delivery pipe is connected to the bottom of the purification box. An air jet assembly is installed on the outer wall of the fixed mounting frame.

[0008] Used to absorb and treat paint mist inside the fixed mounting frame, preventing paint from directly escaping to the outside. When the air pump is started, the paint mist inside the fixed mounting frame is transported to the purification chamber through the air suction hood, air extraction pipe and air delivery pipe in sequence, so as to avoid paint mist from polluting the air and avoiding paint mist from affecting the health of the staff.

[0009] Preferably, a plurality of pairs of fixed partitions are fixedly installed inside the purification box, the air supply pipe is located below the fixed partitions, a plurality of air passage holes are opened on one side of the top of the pair of fixed partitions, the air passage holes on the fixed partitions located below are located away from the air supply pipe, the pair of fixed partitions are symmetrically arranged, and the purification box is filled with active adsorption material.

[0010] It is used to purify the paint mist absorbed into the purification chamber. The symmetrically arranged air vents make the paint mist transport path longer, which facilitates more thorough purification of the paint mist by the activated adsorption material.

[0011] Preferably, the jet assembly includes a jet main pipe fixedly installed on the outer wall of the fixed mounting frame, a guide pipe connected to the center of the jet main pipe, the other end of the guide pipe connected to the purification box, the end of the guide pipe being positioned above a pair of fixed partitions, and high-pressure nozzles being evenly connected to the bottom of the guide pipe at equal intervals.

[0012] It is used to quickly spray out purified air. The purified air is delivered to the jet main pipe through the air guide pipe, and then sprayed out through the high-pressure nozzle. The flowing gas facilitates the drying process of the I-beam.

[0013] Preferably, the spraying mechanism includes a main spraying pipe, which is fixedly installed on the top of the fixed mounting frame and is connected to the paint source. The main spraying pipe is connected to a pair of spraying tubes, which are fixedly inserted into the fixed mounting frame. The pair of spraying tubes are symmetrically fixedly installed on the inner side wall of the fixed mounting frame, and the pair of spraying tubes are connected to a plurality of spraying nozzles.

[0014] A pair of suction hoods are symmetrically arranged on both sides of the paint spraying main pipe;

[0015] Used for spraying H-beams, the paint source is delivered to a pair of spray pipes through the main spray pipe, and then sprayed onto the H-beams through the spray nozzles.

[0016] Preferably, the processing platform has a movable groove in the center, and several electric rollers are rotatably installed in the movable groove. I-beams are set above the electric rollers, and support legs are fixedly installed at the four corners of the bottom of the processing platform.

[0017] Used for conveying I-beams.

[0018] This utility model has the following beneficial effects:

[0019] 1. By setting up a purification mechanism and starting the air pump, the paint mist in the fixed mounting frame is transported sequentially to the purification chamber through the air suction hood, air extraction pipe and air delivery pipe. The symmetrically arranged air passages make the paint mist transport path longer, which facilitates more thorough purification of the paint mist by the active adsorption material, avoids paint from directly escaping to the outside, avoids paint mist from polluting the air, and avoids paint mist from affecting the health of the staff.

[0020] 2. By setting up an air jet assembly, the purified air is delivered to the main air jet pipe through the air guide pipe, and then the gas is sprayed out through the high-pressure nozzle. The flowing gas facilitates the drying process of the I-beam. Attached Figure Description
