Description

Technical Field

[0001] The utility model relates to the technical field of experimental platforms, in particular to a multifunctional experimental platform for detecting silicon dioxide content in iron ore. Background Art

[0002] Iron ore is an important raw material for steel production enterprises. Natural ore (iron ore) is gradually separated from iron through crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. Iron ore is a mineral aggregate containing iron or iron compounds that can be economically utilized. Silicon content is the main technical indicator for iron ore quality control. Its determination methods include mass method, potassium fluorosilicate volumetric method, spectrophotometry, etc.

[0003] The laboratory bench is a table used by enterprises and institutions such as hospitals, schools, chemical plants, and scientific research institutes for experimental testing and storage of instruments. At present, most of the laboratory benches on the market are equipped with a liquid delivery pipe and a liquid collection box inside, so that the laboratory bench can collect waste liquid that cannot be directly dumped separately, and filter out the waste residue in the waste liquid through a filter. For example, a new multifunctional laboratory bench disclosed in Chinese patent announcement number CN207805670U, but because the filtered waste residue is accumulated on the filter, the waste liquid often cannot pass through the filter quickly due to the accumulation of waste residue on the filter. At the same time, when dumping the waste liquid, the waste liquid will contact the inner wall of the liquid delivery pipe, which causes the experimenter to clean the inner wall of the liquid delivery pipe after the experiment, which makes the laboratory bench more troublesome to clean. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. For example, at present, most of the experimental benches on the market are equipped with a liquid delivery pipe and a liquid collecting box inside, so that the experimental bench can collect waste liquid that cannot be directly dumped separately, and filter out waste residues in the waste liquid through a filter. However, since the filtered waste residues are accumulated on the filter, the waste liquid often cannot pass through the filter quickly due to the accumulation of too much waste residue on the filter. At the same time, when dumping the waste liquid, the waste liquid will contact the inner wall of the liquid delivery pipe, so the experimenter needs to clean the inner wall of the liquid delivery pipe after the experiment, which makes the cleaning of the experimental bench more troublesome. A multifunctional experimental bench for detecting the silicon dioxide content in iron ore is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A multifunctional experimental table for detecting silicon dioxide content in iron ore comprises a base, wherein the upper surface of the base is fixedly connected with a cabinet, the upper surface of the cabinet is fixedly connected with a table, the upper surface of the base is fixedly connected with a U-shaped column, the inner wall of the U-shaped column and the upper surface of the base are both fitted with a liquid collecting box, the left and right sides of the inner wall of the liquid collecting box are both fixedly connected with a slag collecting box, the front and rear sides of the inner wall of the liquid collecting box are both fixedly connected with a U-shaped plate, the inner wall of the U-shaped plate and the front and rear sides of the inner wall of the liquid collecting box are both fitted with an elastic filter screen, a first circular hole is opened inside the table, a first bearing is fixedly connected to the inner wall of the first circular hole, a liquid inlet pipe is fixedly connected to the inner wall of the first bearing, a first gear is fixedly connected to the surface of the liquid inlet pipe, a second circular hole is opened inside the table, a hand-cranked bracket is fixedly connected to the inner wall of the second circular hole, the hand-cranked bracket is meshed with the first gear, the left and right sides of the liquid inlet pipe are both fixedly connected with connecting columns, and a spherical block is fixedly connected to the bottom of the connecting column.

[0007] Preferably, the elastic filter screen includes a vertical plate, the inner wall of the U-shaped plate and the front and rear sides of the inner wall of the liquid collecting box are in contact with the surface of the vertical plate, the bottom of the vertical plate is fixedly connected with a spring, the bottom of the spring is in contact with the inner wall of the U-shaped plate, the left and right sides of the vertical plate are fixedly connected with a stainless steel filter screen, and the front and rear sides of the stainless steel filter screen are in contact with the inner wall of the liquid collecting box.

[0008] Preferably, the elastic force of the spring is greater than the sum of the gravity of the vertical plate and the stainless steel filter screen.

[0009] Preferably, the center of the vertical plate and the center of the liquid inlet pipe are on the same vertical line.

[0010] Preferably, the hand crank bracket includes a hand crank handle, the bottom of the hand crank handle is fixedly connected to a cylinder, the surface of the cylinder and the inner wall of the second circular hole are fixedly connected to a second bearing, the surface of the cylinder is fixedly connected to a second gear, and the second gear is meshed with the first gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model enables the user to rotate the liquid inlet pipe by rotating the hand-cranked bracket through the cooperation of the first gear and the second gear. At the same time, when the liquid inlet pipe rotates, the stainless steel filter on the elastic filter can be shaken up and down through the cooperation of the connecting column, the spherical block, the U-shaped plate and the elastic filter. At this time, the waste residue on the stainless steel filter can slide into the residue collecting box through the shaking, thereby preventing the waste liquid from being unable to pass through the stainless steel filter quickly due to the accumulation of a large amount of waste residue on the stainless steel filter.

[0014] (2) The utility model can fix the rubber isolation bag in the liquid inlet pipe through the cooperation of the support ring, the magnetic block and the positioning groove. Moreover, when the rubber isolation bag is fixed in the liquid inlet pipe, the rubber isolation bag can prevent the waste liquid from contacting the inner wall of the liquid inlet pipe when the user pours out the waste liquid. After the experiment is completed, the user can keep the inner wall of the liquid inlet pipe clean by replacing the new rubber isolation bag, thereby making the laboratory table more convenient to clean.
