Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of tungsten wire powder scraping, and specifically relates to an inner soot blowing box for tungsten wire powder scraping. Background Art
[0002] Tungsten wire is mainly used in electric light sources such as incandescent lamps and halogen tungsten lamps. Tungsten wire used as various illuminants in bulbs also needs to be doped with a small amount of potassium, silicon and aluminum oxides during the smelting process. This kind of tungsten wire is called doped tungsten wire, also known as 218 tungsten wire or non-drooping tungsten wire. Tungsten wire is generally drawn by various wire drawing dies.
[0003] During the tungsten wire production process, when the tungsten wire passes through the mold during hot drawing, the graphite powder previously applied on the surface of the tungsten wire will be scraped off, and the powder will naturally fall into the collection box under the mold.
[0004] As the process matures, the drawing speed and production length are gradually improved. The conventional method of the powder produced by demolding falling by its own gravity can no longer meet the requirements. After a long period of drawing production, the powder will accumulate between the tungsten wire and the mold, and usually requires manual observation and cleaning. If it is not cleaned in time, it will cause abnormal tungsten wire loop diameter, and in severe cases it will cause wire breakage during production. Utility Model Content
[0005] In order to solve the above problems, this paper proposes an internal ash blowing box for tungsten wire scraping powder, the internal ash blowing box includes a scraper box and an ash collecting box, the interior of the scraper box is longitudinally divided into scraper dividing panels, and tungsten wires are arranged on the left and right sides of the scraper box transversely penetrating the center of the scraper dividing panels. The bottom surface of the scraper box is connected with the ash collecting box through the lower ash port, and the scraper dividing panels are arranged on the inner side of the scraper box in a concave left and convex right manner. A scraper hole is arranged in the center of the scraper dividing panel, and air entrainment plates and ash guide plates are arranged on both sides of the scraper hole on the left side of the scraper dividing panel. The ash guide plates are outwardly expanded and arranged on both sides of the scraper hole, and an air entrainment plate is arranged between the ash guide plates on both sides. The rear end of the ash guide plate A main ash discharge port is provided at the bottom, the air ducting plate is arranged inwardly on both sides of the scraper hole, an air blowing port is provided above the air ducting plate, the air blowing port is connected with the top of the scraper box through a bent pipe, an air supply pipe is provided at the outer end of the air blowing port, an air pipe bracket is provided on the outer side of the air supply pipe, an air valve is provided at the outer end of the air supply pipe, and an auxiliary ash discharge port is provided below the scraper hole on the right side of the scraper dividing plate. Air blowing replaces the original natural falling method of powder, which can more quickly and reliably remove powder accumulation, blow away the accumulation between the tungsten wire and the mold, greatly improve product quality, effectively reduce the wire breakage rate, and automatically control the air blowing, save manual cleaning operations, and improve work efficiency.
[0006] The scraper box is in the shape of a rectangular shell, and inlet and outlet holes are arranged in the center of the left and right side surfaces of the scraper box. Rubber dust covers are arranged on the inner sides of the inlet and outlet holes. The diameter of the central through hole of the rubber dust cover is smaller than the diameter of the tungsten wire. An air blowing port is arranged through the upper surface of the scraper box, and an air pipe bracket is arranged aligned with the outer side of the center of the air blowing port. The air pipe bracket is vertically arranged on the upper surface of the scraper box. The scraper box can allow the tungsten wire to pass through the scraper hole and leave the scraped powder inside the scraper box to prevent it from polluting the environment, and the scraped dust is continuously blown off through the air blowing port inside the scraper box to prevent accumulation.
[0007] The shape of the ash collecting box is a rectangular shell with the same outer contour as the scraper box. An ash box air outlet cover is provided at the outer end of the ash collecting box. The surface of the ash box air outlet cover is provided with an anti-ash air grid. The dust blown down is collected by the ash collecting box to prevent it from splashing inside the scraper box, and the ash box air outlet cover can discharge the gas blown out of the air port from the ash collecting box to prevent pressure imbalance in the scraper box, and the anti-ash air grid can prevent dust from being blown out.
[0008] The scraper dividing plate is in the shape of an equilateral trapezoidal folding plate, and the corners of the scraper dividing plate are provided with transition arcs. The scraper dividing plate is longitudinally arranged inside the scraper box, and the upper and lower side edges of the scraper dividing plate are connected to the upper and lower surfaces inside the scraper box. An air ducting plate is provided between the left surface of the scraper dividing plate and the left inner surface of the scraper box. The scraper dividing plate is used to seal and separate the interior of the scraper box, thereby ensuring that most of the scraped dust falls on only one side, and there is a secondary ash outlet below the other side of the discharge to directly drop a small part of the dust moving outward. Since the tungsten wire is always moving outward, it will pull the dust to drop outward, and there will be no dust accumulation on one side of the discharge.
[0009] The ash guide plate is an obtuse-angled folded edge plate, one side of the ash guide plate is parallel to the bottom of the scraper box, and the other side of the ash guide plate is obliquely directed toward the upper side of the scraper hole. Main ash outlets are provided below the ends of the lower surfaces of the horizontal sides of the ash guide plates on both sides. The blown dust can be passed along the bottom of the ash guide plate through the main ash outlet into the ash collecting box, thereby ensuring that the dust can accurately fall into the ash collecting box, and the blown gas can also enter the ash collecting box together, ensuring the stability of the air duct inside the scraper box.
[0010] The air guide plate is an obtuse-angled folded plate, one side of the air guide plate is vertically arranged on both sides of the scraper hole, and the other side of the air guide plate is obliquely toward the bottom side of the scraper hole. The edge of the air guide plate is connected to the left surface of the scraper dividing plate. The upper end width of the air guide plates on both sides is the same as the width of the air blowing port, and the lower end width of the air guide plates on both sides is smaller than the width on both sides of the upper end of the ash guide plate. The gas blown out from the top can be guided to the lower side of the scraper port through the air guide plate, ensuring that the dust on the lower side of the scraper port can also fall smoothly.
[0011] The air outlet includes a flat air outlet nozzle and an air pipe. The air pipe is a bent circular tube. The outer surface of the air pipe is connected to the upper surface of the scraper box. One end of the air pipe passes through the upper surface of the scraper box, and the other end of the air pipe is connected to the flat air outlet nozzle. The flat air outlet nozzle is aligned above the scraper hole. The gas is evenly blown toward the scraper hole through the air outlet, ensuring the stability of the gas and a sufficient flow rate.
[0012] Beneficial effects:
[0013] Air blowing replaces the original natural powder falling method, which can remove powder accumulation more quickly and reliably, blow away the accumulation between the tungsten wire and the mold, greatly improve product quality, effectively reduce the wire breakage rate, and automatically control the air blowing, saving manual cleaning operations and improving work efficiency.
[0014] The scraper box allows the tungsten wire to pass through the scraper hole and the scraped powder will remain inside the scraper box to prevent it from polluting the environment. The scraped dust is continuously blown off through the air outlet inside the scraper box to prevent accumulation.
[0015] The dust blown down is collected by the ash collecting box to prevent it from splashing inside the scraper box, and the ash box air outlet cover can discharge the gas blown out from the air port from the ash collecting box to prevent pressure imbalance in the scraper box, and the anti-ash air grid can prevent dust from being blown out.
[0016] The scraper box is sealed and separated by a scraper dividing plate to ensure that most of the scraped dust falls on only one side. There is also a secondary ash outlet at the bottom of the other side of the discharge to directly drop a small part of the dust moving outward. Since the tungsten wire moves outward all the time, it will pull the dust outward, so there will be no dust accumulation on one side of the discharge.
[0017] The blown dust can be guided along the bottom of the ash guide plate through the main ash outlet into the ash collecting box, thereby ensuring that the dust can fall accurately into the ash collecting box, and the blown gas can also enter the ash collecting box together, ensuring the stability of the air duct inside the scraper box.
[0018] The air blown from above can be guided to the lower side of the scraper port through the air guide plate, ensuring that the dust on the lower side of the scraper port can also fall smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
