Description
Technical Field
[0001] This utility model relates to the field of dust collection technology, specifically a dust collection device for magnesium alloy polishing. Background Technology
[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements. Their characteristics include low density, high strength, high elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloys, and good resistance to corrosion from organic matter and alkalis. The main alloying elements include aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. Magnesium-aluminum alloys are the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. They are mainly used in aerospace, transportation, chemical, and rocket industries. The dust generated during the polishing process of magnesium alloys is flammable and explosive. Traditional dust collection devices mostly collect dust in a simple way, but dust adhering to the surface of the filter cartridge can easily cause blockage and safety problems. In addition, traditional hammer vibration dust removal can easily generate sparks, which can also cause safety problems. This affects the working efficiency of the device, and dust accumulation in one space is not safe. Therefore, we propose a magnesium alloy polishing dust collection device. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a magnesium alloy polishing dust collection device. It completely eliminates mechanical friction sparks through the non-contact dust removal design of electromagnet-magnetic plate, and at the same time uses a sealing plate to separate a large amount of dust, effectively preventing the risk of magnesium powder explosion and significantly improving safety. It is particularly suitable for high-risk dust operation environments such as magnesium alloy polishing and can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnesium alloy polishing dust collection device, comprising a dust collection box and a fixing plate; Dust collection box: The air inlet on the front side is connected to one end of the conveying hose, and the other end of the conveying hose is connected to the air outlet of the dust collection hood. A box cover is hinged to the rear side of the top surface of the dust collection box. A negative pressure fan is fixedly installed on the surface of the box cover. A fixing plate is fixed inside the dust collection box. A filter cartridge is inserted into the through hole on the surface of the fixing plate. A cleaning unit is provided inside the dust collection box. A collection unit is provided at the bottom of the dust collection box. It also includes a controller, which is located on the surface of the dust collection box. The input end of the negative pressure fan is electrically connected to the output end of the controller, and the input end of the controller is electrically connected to the output end of an external power source.
[0005] The negative pressure fan is turned on to draw the dust generated during the polishing of magnesium alloy through the dust collection hood into the dust collection box, where the filter cartridge can filter the dust.
[0006] Furthermore, the cleaning unit includes a vibration motor, a bracket, a frame, springs, a linear motor, an electromagnet, and a magnetic plate. There are two linear motors, each fixed to the front and rear sides inside the dust collection box. The inner side of the linear motor's moving part is connected to the end of the frame. The inside of the frame is slidably installed with the bottom of the bracket. Springs are installed on both the front and rear sides inside the frame, with the inner ends of the springs connected to the surface of the bottom of the bracket. Electromagnets corresponding to the positions of the filter cartridges are evenly distributed on the top surface of the bracket. The magnetic plate is fixed to the bottom surface of the filter cartridge. Vibration motors are installed on both sides of the bottom surface of the bracket. The input ends of the vibration motors and linear motors are electrically connected to the output end of the controller. Starting the linear motors moves the bracket, and the electromagnets and magnetic plate magnetically attract and fix the filter cartridge. The vibration motors, in conjunction with the springs, cause the filter cartridge to vibrate at high frequency and micro-amplitude, thus solving the risk of metal friction sparks that are easily generated by traditional hammering, thereby ensuring the safety of the device.
[0007] Furthermore, the collection unit includes an inclined guide seat, a motor, a screw, a limiting frame, a sealing plate, a collection box, and a rubber strip. There are two inclined guide seats, each fixed to one of the left or right sides inside the dust collection box. There are also two motors, each fixed to one of the left or right sides of the dust collection box. The output shaft of each motor is connected to the outer end of the screw. A limiting frame is fixed to the top surface of the sealing plate, and the limiting frame is slidably installed in the limiting groove on the bottom surface of the inclined guide seat. The screw is threadedly connected to a screw hole on the surface of the sealing plate. A rubber strip is adhered to the inner side of the sealing plate. The collection box is slidably installed at the bottom of the dust collection box. The input end of the motor is electrically connected to the output end of the controller. Dust that falls during cleaning passes through the inclined guide seat and falls into the collection box for collection, facilitating cleaning. The motor driving the screw to rotate causes the two sealing plates to close in conjunction with the rubber strip, thereby increasing the sealing performance of the device.
[0008] Furthermore, it also includes a dust concentration sensor and a material level sensor. The dust concentration sensor is fixed on the left side of the dust collection box, and the material level sensor is installed on the front side of the collection box. The output terminals of the dust concentration sensor and the material level sensor are electrically connected to the input terminal of the controller. The dust concentration sensor can detect the dust concentration in the box, while the material level sensor can prevent the dust inside the collection box from accumulating too much and prevent overload discharge.
[0009] Furthermore, it also includes a clamping frame and a filter screen. The clamping frame is fixed to the bottom surface of the box cover, and the filter screen is inserted into the mesh groove on the surface of the dust collection hood. The clamping frame can fix the filter cartridge, while the filter screen can prevent larger impurities from entering the interior of the dust collection box.
[0010] Furthermore, it also includes alarm lights. There are two alarm lights, which are fixed to the rear side of the dust collection box, one on the left and one on the right. The input of the alarm lights is electrically connected to the output of the controller. The alarm lights can flash to alert personnel when a problem is detected.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This magnesium alloy polishing dust collection device has the following advantages: 1. The linear motor drives the support to move, and the filter cylinder is fixed by the magnetic attraction of the electromagnet and the magnetic plate. The vibration motor, together with the spring, makes the filter cylinder vibrate at high frequency and micro amplitude to solve the risk of metal friction sparks that are easy to occur by traditional hammering, thereby ensuring the safety of the device. 2. The dust that falls off is collected inside the collection box by the inclined guide seat, which makes it convenient for personnel to clean. The motor drives the screw to rotate, which allows the two sealing plates to close with the rubber strip, thereby increasing the sealing of the device. 3. The dust concentration sensor can detect the dust concentration inside the box, while the material level sensor can prevent excessive dust accumulation inside the collection box and prevent overload discharge.
