Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, in particular to a workshop dust removal device. Background Art
[0002] Ironmaking is the process of extracting metallic iron from iron-containing minerals (mainly iron oxides). There are mainly blast furnace method, direct reduction method, molten reduction method and plasma method. From a metallurgical point of view, ironmaking is the reverse behavior of iron rusting and gradual mineralization. Simply put, pure iron is reduced from iron-containing compounds. In actual production, pure iron does not exist, and what is obtained is iron-carbon alloy.
[0003] In the ironmaking workshop, there are various dusts that affect the workshop environment, and a dust removal device is needed to remove dust in the workshop. However, most of the dust in the workshop is recyclable iron filings, and traditional dust removal devices cannot recycle this part of the iron filings for reuse. Therefore, we propose a workshop dust removal device. Utility Model Content

DETAILED DESCRIPTION
[0026] See also Figure 1-4 The utility model provides a technical solution: a workshop dust removal device, including a dust removal frame 1 and a support block 2. The four corners of the bottom of the dust removal frame 1 are supported and fixed with supporting feet. There are four supporting feet with the same length to achieve lateral stable support for the dust removal frame 1.
[0027] The support block 2 is fixed at the lower part of the interior of the dust removal frame 1, and a filter screen 21 is fixed obliquely between the support block 2 and the upper inner wall of the dust removal frame 1. The filter screen 21 is tilted to the right, and a second ring frame 6 is fixed around the right outer surface of the dust removal frame 1. The inner circle of the second ring frame 6 is connected to the interior of the dust removal frame 1, and the left side of the dust removal frame 1 is directly connected to the outside, so that the second ring frame 6 acts as an air inlet, and the left side of the dust removal frame 1 is an air outlet.
[0028] A support groove 22 is provided on the surface of the support block 2 on the side of the filter 21, and a fan 3 is supported obliquely above the support block 2 through the support groove 22. The fan 3 is arranged parallel to the filter 21, and a through-hole 11 is provided on the surface of the dust removal frame 1 above the fan 3. The fan 3 passes through the through-hole 11 to the outside of the dust removal frame 1. When the fan 3 is started, air is blown toward the left side, so that air enters from the second ring frame 6 and is discharged from the left side after being filtered by the filter 21.
[0029] A first ring frame 5 connected to the interior of the dust removal frame 1 is fixed around the bottom surface of the dust removal frame 1 below the filter screen 21, a filter basket 51 is arranged below the first ring frame 5, and a ring plate 511 is fixed around the upper outer ring of the filter basket 51, the ring plate 511 is in contact with the bottom of the first ring frame 5, and the front and rear ends of the ring plate 511 are locked under the first ring frame 5 by hand-tightening bolts 512 to lock the filter basket 51, and the hand-tightening bolts 512 penetrate the ring plate 511 through the reserved holes on the surface of the ring plate 511, and then are screwed into the screw holes reserved on the lower surface of the first ring frame 5 to fix the ring plate 511 and the filter basket 51, and the dust left by the filter screen 21 falls due to gravity and can be directly collected inside the filter basket 51.
[0030] The first ring frame 5 has the same size as the second ring frame 6. In order to prevent airflow from entering the dust removal frame 1 from the filter basket 51 during dust filtering, a cover 7 is fixedly sleeved on the outer ring of the first ring frame 5 so that the filter basket 51 is located on the inner side of the cover 7. In addition, a rubber pad 71 is fixedly fitted on the inner surface of the cover 7. The rubber pad 71 contacts the outer surface of the first ring frame 5 to prevent slipping.
[0031] A group of conductive contacts 221 are arranged on one side surface of the support groove 22, and a group of conductive sheets 31 are arranged on both sides of the bottom of the fan 3, respectively. The conductive sheets 31 are arranged symmetrically with each other, and the two groups of conductive sheets 31 are electrically connected to the fan 3, so that the conductive contacts 221 are connected to the power supply. The upper surface of the fan 3, the middle position of the surface of the cover 7 and the lower part of the two sides of the ring plate 511 are fixed with handles 4. When in use, the cover 7 is first removed downward by using the handle 4, and then the cover 7 is put on the outer ring of the second ring frame 6, so that the rubber of the inner ring of the cover 7 is The rubber pad 71 is pressed against the outer surface of the second ring frame 6 and locked, blocking the second ring frame 6. After that, the fan 3 can be pulled out upward through the handle 4, and then turned over and inserted from the through-opening 11. The bottom of the fan 3 is supported in the support groove 22 again, so that the conductive contact 221 contacts with another set of conductive sheets 31 to make the fan 3 powered and work, so that the fan 3 can blow air downward and finally pass through the filter basket 51 for discharge, so that the airflow can blow down and clean the dust left on the lower surface of the filter 21, and finally collect it in the filter basket 51.
[0032] When in use, the conductive contact 221 is connected to a power source. Since the bottom of the fan 3 is supported in the support groove 22, a group of conductive sheets 31 on one side will contact the conductive contact 221, so that the fan 3 is powered and works, and the fan 3 blows air to the left, which will cause the air in the workshop to enter the dust removal frame 1 from the inner side of the second ring frame 6 on the right side, and then be filtered by the filter 21 to leave the dust on the right side surface of the filter 21, and then flow to the left side and be discharged. The dust adsorbed on the lower right surface of the filter 21 will fall under the action of gravity and be collected in the filter basket 51. When a period of use causes a lot of dust to accumulate on the lower right surface of the filter 21, the cover 7 can be pulled downward to remove it, and then it can be put on the outer ring of the second ring frame 6 on the right side (such as Figure 2 As shown), at this time, the fan 3 is pulled upward by the handle 4, turned over and inserted again from the through hole 11, and the bottom is supported in the support groove 22. At this time, the conductive contact 221 contacts with another group of conductive sheets 31 at the bottom of the fan 3 and keeps the power supply state. However, since the direction of the fan 3 is changed, the fan 3 will work to blow air to the right side. After passing through the filter screen 21, the airflow flows downward and passes through the filter basket 51, and the dust covered on the lower surface of the right side of the filter screen 21 is cleaned and blown off and finally collected in the filter basket 51. After that, the locking ring plate 511 and the hand screw bolt 512 of the filter basket 51 can be unscrewed, and the iron filings and dust collected in the filter basket 51 are poured out and collected, and then fixed under the first ring frame 5 again by the same method, and then the cover 7 sleeved on the outer ring of the second ring frame 6 is removed, and it is sleeved on the lower outer ring of the first ring frame 5 to fix it. Finally, the fan 3 is pulled out and turned over again for continuous dust removal.
