Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation, and in particular to a flow trough iron removal device. Background Art

[0002] For the production of building gypsum, waste acid and carbide slag can be used to produce building gypsum, which can not only solve the pollution and harm caused by waste acid and carbide slag to the environment, but also realize the recycling and utilization of the two wastes. In the gypsum production sites and waste acid treatment sections of smelting enterprises, they have long been troubled by the high iron content in carbide slag, which affects the production quality of gypsum products.

[0003] The iron content in carbide slag is high, and the iron slag will precipitate and agglomerate in the slurry tank, causing serious wear and tear on the subsequent slurry conveying equipment. In order to reduce the damage to subsequent equipment, it is necessary to frequently stop the pump and clean the iron slag in the slurry tank, which is not only labor-intensive, but also seriously affects the stability of production.

[0004] In this regard, conventional methods are to install several magnetic bars in the slurry tank to absorb the iron slag, which has a certain iron removal effect. However, when the magnetic bars are full of iron slag, they need to be cleaned. When cleaning, the magnetic bars need to be taken out from the slurry tank one by one. Due to the complex installation structure and the cumbersome assembly and disassembly of the magnetic bars, the cleaning intensity is high and it takes a lot of time. In addition, it is difficult to clean the adhered iron slag in a centralized and unified manner. Summary of the invention

[0005] In order to solve the problems that conventional iron removal operations are cumbersome and iron removal facilities are inconvenient to clean, the utility model provides a flow chute iron removal device, in which a plurality of plastic sleeves are arranged in an iron removal box, each sleeve is provided with a magnetic rod, the magnetic rods are uniformly connected to each other, and a plurality of magnetic rods can be operated at the same time, thereby realizing convenient iron removal. At the same time, the cleaned iron slag can all fall to the bottom of the iron removal box and be cleaned uniformly.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A chute iron removal device is installed in front of a slurry tank and connected thereto, comprising an iron removal box and a magnetic bar group arranged in the iron removal box, so as to facilitate iron removal of the slurry flowing into the iron removal box. The front and rear ends of the iron removal box are respectively provided with a liquid inlet and a liquid outlet, so as to facilitate the inflow and outflow of the slurry. The bottom surface of the iron removal box is provided with an iron slag cleaning port with a flange plate, so as to facilitate centralized and unified cleaning of the iron slag.

[0008] There are multiple groups of magnetic rods, which improves the cleaning effect of iron slag. The multiple groups of magnetic rods are arranged equidistantly along the length direction of the iron removal box, and each group of magnetic rods includes a mounting plate, a plastic sleeve, a magnetic rod and an operating crossbar;

A plurality of the plastic sleeves with closed lower ends and open upper ends are threadedly connected to the installation plate, and the lower ends of the plastic sleeves extend downward into the iron removal box;

[0010] A magnetic rod is inserted into the plastic sleeve, which can protect the magnetic rod. A plurality of magnetic rods in the same magnetic rod group are connected and fixed by the operation cross bar.

The operation cross bar is horizontally arranged above the installation plate, and both ends of the operation cross bar abut against the top surface of the iron removal box and are detachably connected to the top surface of the iron removal box, improving the reliability of the installation of the operation cross bar.

[0011] Further, the iron removal box is a rectangular box structure, the iron slag cleaning port is tubular, the iron slag cleaning port is close to the liquid outlet, and a flange plate for opening and closing the iron slag cleaning port is bolted to the iron slag cleaning port. When the iron removal box is in normal use, the flange plate is in the installed state, and when cleaning the iron slag in the iron removal box, the flange plate is removed.

[0012] Further, the installation plate includes a flat plate and a plurality of installation sleeves arranged equidistantly on the flat plate. The flat plate is bolted to the top surface of the iron removal box, and the lower ends of the installation sleeves penetrate into the iron removal box, which is convenient for positioning the installation plate. A sealing sleeve with a "T" - shaped cross - section is sleeved outside the installation sleeve, and the sealing sleeve is in close fit with the iron removal box, avoiding the leakage of slurry.

[0013] Further, the plastic sleeve is a cylindrical shape with a "凵" - shaped cross - section. The lower end of the plastic sleeve is at a certain distance from the bottom surface of the iron removal box. After the magnetic rod is taken out, the iron slag outside the plastic sleeve falls to the bottom of the iron removal box, and the existing interval can prevent the iron slag from being adsorbed again;

[0014] A limiting ring is arranged on the plastic sleeve, and a threaded section is arranged on the outer wall of the plastic sleeve below the limiting ring; the plastic sleeve is inserted into the installation sleeve, and the plastic sleeve is threadedly connected to the installation sleeve through the threaded section, and the limiting ring abuts against the upper part of the installation sleeve for limiting, which is convenient for restricting the installation position of the plastic sleeve.

[0016] A plurality of screw rods are arranged equidistantly on the operation cross bar, and each screw rod is threadedly connected with the magnetic rod. The magnetic rod is suspended in the plastic sleeve, preventing the weight of the magnetic rod from acting on the plastic sleeve.

Each group of magnetic rod groups contains a plurality of magnetic rods, and the arrangement direction of the plurality of magnetic rods is perpendicular to the flow direction of the slurry. This is equivalent to arranging the magnetic rods in a rectangular array in the iron removal box. The magnetic rods are evenly arranged and can fully contact the slurry, so that the slurry can be evenly, effectively and comprehensively iron-removed.

[0019] The mounting plate of the utility model is bolted to the top surface of the iron removal box, and multiple plastic sleeves are threadedly connected to the mounting plate. Through the mounting plate, multiple plastic sleeves can be conveniently installed in the iron removal box or removed from the iron removal box. A magnetic rod is inserted into each plastic sleeve, and the plastic sleeve plays a protective role for the magnetic rod. Multiple magnetic rods are connected together by an operating cross bar, and multiple magnetic rods can be conveniently installed in the iron removal box or removed from the iron removal box through the operating cross bar, which greatly facilitates the cleaning operation of iron slag.

[0020] When the utility model is used, the slurry passes through multiple magnetic bars arranged in an array in the iron removal box, and the iron slag in the slurry is adsorbed on the surface of the plastic sleeve by the magnetic bars, which can intercept the iron slag, reduce the amount of iron slag entering the next process, reduce the slag caking and agglomeration, and avoid frequent tank cleaning work and damage to subsequent equipment.

DETAILED DESCRIPTION

[0029] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0030] like Figure 1 to Figure 7 As shown, a launder iron removal device is installed in front of a slurry tank and is connected thereto. The slurry first passes through the launder iron removal device to effectively remove the iron slag therein, and then flows into the slurry tank.

[0031] The chute iron removal device comprises an iron removal box 1 and a magnetic bar group 2 arranged in the iron removal box 1. The iron removal box 1 is a rectangular box structure and can be used to contain slurry.

[0032] The iron removal box 1 is provided with a liquid inlet 3 and a liquid outlet 4 at both ends. The slurry enters the iron removal box 1 through the liquid inlet 3, and then the slurry is iron-removed by the magnetic bar group 2. The slurry after iron removal flows out through the liquid outlet 4 and flows to the slurry tank. The function of the magnetic bar group 2 is to adsorb and remove the iron slag contained in the slurry to prevent the iron slag from continuing to exist in the slurry.

[0033] In this embodiment, there are four groups of magnetic bar groups 2, which are arranged equidistantly along the length direction of the iron removal box 1, so as to achieve a uniform and comprehensive iron removal effect. Each group of magnetic bar groups 2 includes a mounting plate 5, a plastic sleeve 6, a magnetic bar 7 and an operating crossbar 8.

[0034] The mounting plate 5 is arranged along the width direction of the iron removal box 1, and the mounting plate 5 is detachably arranged on the top surface of the iron removal box 1. Here, the mounting plate 5 includes a straight plate 51 and four mounting sleeves 52 equidistantly arranged on the straight plate 51, the straight plate 51 and the mounting sleeve 52 are welded and fixed together, and the lower end of the mounting sleeve 52 is inserted into the iron removal box 1, so that the position of the mounting plate 5 can be positioned.

[0035] Specifically, four holes are provided on the top surface of the iron removal box 1, and the holes and the mounting sleeves 52 are arranged one by one. When the mounting plate 5 is installed, the mounting sleeves 52 are inserted into the holes one by one, so that the mounting plate 5 is positioned, which is equivalent to restricting the mounting plate 5. Then, the straight plate 51 is connected to the top surface of the iron removal box 1 with bolts, so that the mounting plate 5 can be fixed on the top surface of the iron removal box 1. The bolts used for installing the straight plate 51 are not shown in the figure.

[0036] Since there is an insertion connection between the mounting sleeve 52 and the hole, to ensure the sealing performance of the iron removal box 1, a sealing sleeve 9 with a "T"-shaped cross-section is sleeved outside the mounting sleeve 52, and the outer wall of the lower end of the sealing sleeve 9 is in the shape of a circular truncated cone, which facilitates the embedding of the sealing sleeve 9 into the hole. After the mounting plate 5 is installed and fixed, the mounting plate 5 will squeeze the sealing sleeve 9, prompting the sealing sleeve 9 to closely fit with the iron removal box 1, and the hole is sealed through the sealing sleeve 9.

[0037] A plurality of plastic sleeves 6 with closed lower ends and open upper ends are threadedly connected to the mounting plate 5. Therefore, the plastic sleeve 6 is a cylindrical shape with a "U"-shaped cross-section. The plastic sleeve 6 is made of pvc material. The lower end of the plastic sleeve 6 extends downward into the iron removal box 1, and there is a certain distance between the lower end of the plastic sleeve 6 and the bottom surface of the iron removal box 1.

[0038] When the plastic sleeve 6 is installed, the plastic sleeve 6 is inserted through the mounting sleeve 52 and is threadedly connected to the mounting sleeve 52. Specifically, a threaded section 10 is provided on the outer wall of the plastic sleeve 6, and the threaded section 10 is processed by threading. The plastic sleeve 6 is threadedly connected to the mounting sleeve 52 through the threaded section 10. The length of the threaded section 10 only accounts for a small part of the entire length of the plastic sleeve 6. The purpose of this is to facilitate the installation of the plastic sleeve 6. The part without the threaded section 10 can be directly inserted into the mounting sleeve 52, and the part with the threaded section 10 is installed through a screwing operation.

[0039] To achieve the limit of the installation of the plastic sleeve 6, a limit ring 11 is provided on the plastic sleeve 6, and the limit ring 11 and the threaded section 10 are arranged vertically. During the process of screwing the plastic sleeve 6, until the limit ring 11 abuts against the upper part of the mounting sleeve 52, at this time the plastic sleeve 6 can no longer rotate, and the installation of the plastic sleeve 6 is completed. The purpose of using the mounting sleeve 52 is to increase the contact area between the plastic sleeve 6 and the flat plate 51, improve the stability of the installation of the plastic sleeve 6, and effectively cope with the impact of the slurry flowing into the iron removal box 1.

[0040] A magnetic rod 7 is inserted into each plastic sleeve 6, which is equivalent to the magnetic rod 7 being wrapped by the plastic sleeve 6 outside. The four magnetic rods 7 in the same magnetic rod group 2 are connected and fixed through an operation cross bar 8. Specifically, the operation cross bar 8 is horizontally arranged above the mounting plate 5, and four screw rods 12 are equidistantly arranged on the operation cross bar 8. Each screw rod 12 is threadedly connected to a magnetic rod 7, so that the magnetic rod 7 is detachable. By manually lifting and lowering the operation cross bar 8, the four magnetic rods 7 can be driven to move up and down, move out or move into the plastic sleeve 6 together.

[0041] Since the magnetic bar 7 is arranged in the plastic sleeve 6, in order to avoid the weight of the magnetic bar 7 acting entirely on the plastic sleeve 6, the magnetic bar 7 needs to be suspended. Specifically, the two ends of the operating cross bar 8 are against the top surface of the iron removal box 1, that is, the cross section of the operating cross bar 8 is in a "[" shape, and the two ends of the operating cross bar 8 are bent vertically downward and against the top surface of the iron removal box 1. In this way, the magnetic bar 7 is carried by the operating cross bar 8, the weight of the magnetic bar 7 will be applied to the iron removal box 1, and the installed magnetic bar 7 is suspended in the plastic sleeve 6, that is, there is a gap between the lower end of the magnetic bar 7 and the lower end of the plastic sleeve 6, and the weight of the magnetic bar 7 does not act on the plastic sleeve 6.

[0042] In order to improve the reliability of the installation of the operating cross bar 8, the operating cross bar 8 and the top surface of the iron removal box 1 are detachably connected. Specifically, buckles 13 are respectively provided between the two ends of the operating cross bar 8 and the iron removal box 1 to connect, which can avoid the instability of the simple abutment of the ends of the operating cross bar 8, and the locking of the position of the operating cross bar 8 is achieved through the buckle 13.

[0043] The principle of the utility model is as follows: the iron removal box 1 equipped with the magnetic bar group 2 is arranged in front of the slurry tank, and after the slurry is introduced into the iron removal box 1 through the liquid inlet 3, the slurry flows through the four groups of magnetic bar groups 2, and finally flows into the slurry tank from the liquid outlet 4. During the flow of the slurry in the iron removal box 1, the slurry can be evenly and effectively iron-removed by the four groups of magnetic bar groups 2, and the iron slag therein will be adsorbed by the magnetic bar 7 and then gathered on the outer wall of the plastic sleeve 6, which is equivalent to intercepting the iron slag, thereby realizing the effective removal of the iron slag in the slurry and avoiding damage to subsequent equipment.

[0044] When the iron slag accumulated on the outer wall of the plastic sleeve 6 reaches a certain amount, the iron slag needs to be cleaned. Before cleaning, control the slurry to no longer enter the iron removal box 1, and also control the slurry to no longer flow out of the iron removal box 1, that is, the liquid inlet 3 and the liquid outlet 4 are both in a closed state. When cleaning, unlock the buckle 13, disconnect the restriction of the iron removal box 1 on the operating cross bar 8, manually lift the operating cross bar 8 upward, and then the four magnetic bars 7 connected to the operating cross bar 8 gradually move out of the plastic sleeve 6. After the iron slag loses its adsorption force, it falls from the outer wall of the plastic sleeve 6 and falls to the bottom of the iron removal box 1.

[0045] At the same time, a slag cleaning port 15 with a flange plate 14 is provided on the bottom surface of the iron removal box 1, and the slag cleaning port 15 is close to the liquid outlet 4. The slag cleaning port 15 is tubular, and a flange plate 14 for opening and closing the slag cleaning port 15 is bolted to the slag cleaning port 15. After the flange plate 14 is removed, the slag cleaning port 15 is opened, and the slurry in the iron removal box 1 and the cleaned slag flow out from the slag cleaning port 15 together, thereby intercepting and cleaning the slag.

[0046] After the chute iron removal device of the utility model is put into use, it is only necessary to clean the iron slag in the iron removal box 1 regularly, which reduces the number of unplanned chute cleaning times in the production process, greatly improves the production stability of the slurry tank, eliminates the impact on subsequent equipment, reduces the labor intensity of operators, reduces production costs, can bring certain economic and social benefits, and can be promoted and applied.

[0047] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
