Description

Technical Field

[0001] The present invention relates to the technical field of gas purification, in particular to a gas purification device for mechanical processing. Background Art

[0002] Mechanical processing refers to the process of changing the shape, size or performance of a workpiece through mechanical equipment in the factory. There will be a large amount of waste gas generated during workpiece processing in the mechanical processing workshop. The main function of the gas purification device is to remove harmful gases, dust and oil mist generated during the workpiece processing process to ensure the safety of the working environment and the normal operation of the equipment. The gas purification device can effectively improve the mechanical processing environment, protect the health of operators, extend the life of equipment, and meet environmental protection requirements.

[0003] The patent with publication number CN210699366U discloses a gas purification device, including a purification box and a filter plate, wherein the outer surface of the purification box is provided with a reaction gas inlet and an air outlet hole, wherein the filter plate comprises a lower filter plate, the bottom of the lower filter plate is fixed to the bottom of the inner cavity of the purification box, the top of the lower filter plate is fixed to the right side surface of the inner cavity of the purification box, and the reaction gas inlet is located between the two connection points between the lower filter plate and the purification box. In the gas purification device, the gas enters from the reaction gas inlet and passes through the lower plate holes opened inside the lower filter plate and enters the interior of the purification box. The lower filter plate can filter larger particles in the gas, and then the spray pipe sprays and washes the gas located inside the purification box to further reduce the solid particles in the gas, thereby preventing a large number of solid particles in the gas from adhering to the outside of the gas adsorption cotton layer.

[0004] However, the current gas purification device has the following problems: when the gas purification device is in use, since the gas purification device is in the process of purifying the air in the machining workshop, a large amount of workshop dust is easily attached to the dust filter screen in the equipment, which in turn causes a large amount of dust particles and metal particles to adhere to the screen surface, resulting in poor air purification effect. Therefore, we propose a gas purification device for machining. Summary of the invention

[0014] The present invention provides a gas purification device for mechanical processing, which has the following beneficial effects: (1) The present invention comprises a cylinder shell, an air suction hood, an air pump, a round cover, a mesh frame, an activated carbon plate, a heat dissipation shell, a servo motor, a screw, a round straight tube, a scraper and a V-shaped frame in combination with a U-shaped rod.

During the downward movement of the scraper, the scraper scrapes off the dust particles and metal particles on the mesh surface of the mesh frame, thereby preventing a large amount of dust particles and metal particles from adhering to the mesh surface of the mesh frame, resulting in poor air purification effect.

[0015] (2) The present invention sets an anti-adhesion device so that the cross bar, L-shaped frame and arc plate cooperate with the sponge block. The arc plate drives the sponge block to move downward. During the downward movement of the sponge block, the sponge block wipes the spiral groove of the screw, so that a large amount of dust particles and metal particles will not accumulate in the spiral groove of the screw, thereby preventing a large amount of dust particles and metal particles from accumulating in the spiral groove of the screw, causing the screw to be easily damaged by aging.

[0016] (3) The present invention sets an anti-adhesion device so that the square plate, the slide rod, the rubber pad and the circular plate cooperate with the spring. The rubber pad contacts the cylinder shell during the downward movement.

The arc-shaped spring piece slides on the mesh surface of the mesh frame, and the mesh surface of the mesh frame vibrates, so that the dust in the gaps of the mesh surface is shaken off, thereby preventing a large amount of dust from remaining in the gaps of the mesh surface of the mesh frame, resulting in poor air dust purification effect of the mesh surface of the mesh frame.

[0018] (5) The present invention arranges the amplitude device so that the ring block and the inclined plate cooperate with the pad. When the pad moves downward, the vibration on the thin rod is transmitted to the pad, and the pad transmits the vibration to the scraper, so that the scraper vibrates to scrape off the dust particles and metal particles on the mesh surface of the screen frame, thereby preventing the dust particles and metal particles on the mesh surface from being difficult to scrape off cleanly, resulting in poor mesh surface air intake effect.

Under the elastic force of the spring 169, the arc plate 163 will not hit the cylinder shell 1 when moving downward, so as to prevent the arc plate 163 from hitting the cylinder shell 1 when the equipment is in use, thereby avoiding the problem that the arc plate 163 hits the cylinder shell 1 when the gas purification device purifies the air, causing the arc plate 163 to be easily damaged.
