Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

The invention discloses a closed furnace cover 21 type production device of large-crystal magnesium oxide, which is shown in figure 2 and comprises a hopper 1, a smelting furnace 2, an electrode 3, a cross arm 4, an upright post 5, smoke removing equipment, a filling mechanism 8 and a material conveying device 7.

The material conveying device 7 is specifically a spiral material conveying machine, the material conveying device 7 is arranged below the hopper 1, a feeding port of the material conveying device 7 is communicated with a discharging port of the hopper 1 in a welding mode, and raw materials in the hopper 1 directly fall into the material conveying device 7 under the action of gravity. The spiral material conveyer can convey raw materials at a constant speed by controlling the spiral material conveyer, and the material conveying speed of the spiral material conveyer is adjustable.

And a filling mechanism 8 is arranged between the screw conveyor and the smelting furnace 2, and is used for receiving the raw materials conveyed by the conveying device 7 and uniformly adding the raw materials into the smelting furnace 2.

Fig. 2 shows only a schematic representation of the filling mechanism 8, and with particular reference to fig. 3 and 4, the filling mechanism 8 comprises a support frame 81, a receiving tank 82, a scraper 83, a drive wheel 84 and a idler wheel 85.

The support frame 81 is fixed to the furnace body of the furnace 2. The supporting frame 81 is connected with the feeding device 7 by welding.

The receiving chute 82 is welded to the support frame 81. The receiving trough 82 includes a bottom plate 821 and a side wall plate 822. The base plate 821 is of a circular ring-shaped configuration and the side wall plate 822 is a circular plate configuration disposed along an outer edge of the base plate 821. Side wall plate 822 is located on the upper side of bottom plate 821, and bottom plate 821 is welded to side wall plate 822. The receiving chute 82 is located below the outlet of the feeding device 7 so that the material fed by the feeding device 7 falls directly onto the bottom plate 821.

The scraper 83 includes a plurality of scrapers 831 having different lengths and a support barrel 832. The support barrel 832 is of a cylindrical structure and its axis is disposed vertically. The support cylinders 832 pass through the hollow area of the base plate 821 with a gap between the support cylinders 832 and the inner edge of the base plate 821. An outward flange is integrally formed at the bottom end opening of the supporting barrel 832. The transition position of the wall of the supporting barrel 832 and the flanging is provided with a plurality of hollow blanking ports 8321, and the blanking ports 8321 are distributed at equal angles around the axis of the supporting barrel 832. The scrapers 831 are welded to the outer wall of the support barrel 832 and are equiangularly distributed around the support barrel 832. The included angle between the scraping plate 831 and the cylinder wall of the supporting cylinder 832 is an acute angle, and the included angle between each scraping plate 831 and the cylinder wall of the supporting cylinder 832 is consistent. The scraping plate 831 and the burring are respectively located on the upper and lower sides of the bottom plate 821. When the supporting cylinder 832 rotates around its axis, the scraper 831 scrapes the raw material on the bottom plate 821 into the gap, and the raw material falls from the gap and the blanking port 8321 into the melting furnace 2.

The support frame 81 rotatably supports a plurality of idlers 85. The axis of the idler 85 is horizontal and the idler 85 is distributed at equal angles around the axis of the furnace body. The idler 85 is used for supporting the scraper 83 so as to facilitate the rotation of the scraper 83, and particularly the idler 85 supports the flanging from the lower side.

The support frame 81 also rotatably supports a plurality of drive wheels 84, the drive wheels 84 being located below the bottom plate 821 and in contact with the support barrel 832. The plurality of drive wheels 84 are equiangularly distributed about the support barrel 832. When the external input power tends to drive the driving wheel 84 to rotate, the driving wheel 84 drives the scraper 83 to rotate, so that the scrapers with different lengths rotate and scrape the raw materials in the material receiving groove 82 into the smelting furnace 2. The structure or device for driving the driving wheel 84 to rotate belongs to the direct application of the prior art, and will not be described herein, and related matters are not shown in the drawings. Since the lengths of the scrapers 831 are different from each other, the raw material can be uniformly dropped into the melting furnace 2 from the gaps, thereby improving the quality of the product.

Referring to fig. 5, the furnace 2 is provided with a furnace cover 21, and the furnace cover 21 is located inside the support barrel 832. The furnace cover 21 is provided with an electrode 3 hole 211 and a smoking hole 212.

The electrode 3 holes 211 are provided in three and equiangularly distributed around the axis of the furnace 2, the electrodes 3 corresponding one-to-one to said electrode 3 holes 211. The electrode 3 extends into the furnace 2 through the electrode 3 hole 211. The electrode 3 is clamped to the cross arm 4. The cross arm 4 is provided with a plurality of rollers 41 through a bracket, the cross section of the upright post 5 is rectangular, and the rollers 41 are uniformly arranged on four sides of the upright post 5 respectively and slide by taking the upright post 5 as a track. Since the rollers 41 distributed on the four sides of the upright 5 can provide sufficient restraint, the swinging of the cross arm 4 can be avoided. The up-and-down movement of the cross arm 4 can be controlled through components such as a motor, a speed reducer, a twisted rope and the like, so that production operation is carried out, and the structure for driving the cross arm 4 to ascend and descend belongs to the prior art, and is not described in detail herein.

The smoke removing apparatus includes a cyclone 91, a smoke suction pipe 92, and a dust return pipe 93. The fume suction pipe 92 is communicated with the melting furnace 2 through a fume suction hole 212, and the other end of the fume suction pipe 92 is communicated with the cyclone dust collector 91. A large amount of smoke generated during smelting enters the cyclone dust collector 91 through the smoke suction pipe 92. The dust return pipe 93 is communicated with the dust hopper of the cyclone dust collector 91 and the material conveying device 7, so that the raw materials filtered and deposited by the cyclone dust collector 91 can enter the material conveying device 7 through the dust return pipe 93 and then be added into the smelting furnace 2 again, and the utilization rate of the raw materials is improved.

In summary, the present invention has the following advantages:

the invention belongs to closed smelting, the smelting smoke and dust cannot diffuse outside the furnace, and the smoke and dust generated during smelting is directly sucked into a cyclone dust collector 91. Not only the production environment is good, but also the surrounding environment is not damaged.

And secondly, the spiral material conveying machine and the filling mechanism 8 are utilized to ensure that the materials are discharged uniformly and timely, the product yield is high, and the product quality is good.

And thirdly, the cross arm 4 does not swing during operation, so that the yield is improved by 30 percent, and the proportion of high-quality products is improved by 40 percent.

And fourthly, when the invention is used for operation, one material placing worker is arranged for every three furnaces, and more than ten thousand yuan of wages can be saved for each furnace in one year.

And fifthly, the dust generated in the smelting process is not wasted, but can be reused, so that the cost is saved.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, extension, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
