Description

Technical Field

[0001] The utility model relates to the technical field of a sintering machine loosening device, in particular to a sintering material layer loosening device. Background Art

[0002] Modern sintering is all thick material layer, high negative pressure sintering, which has high requirements on the air permeability of the sintering material layer. However, sintering is often affected by changes in external conditions, the air permeability of the sintering material layer deteriorates, the sintering negative pressure increases, and the terminal temperature decreases, resulting in a decrease in the final sintering quality. In order to improve the air permeability of the sintering material layer and ensure the quality and output of the sintered ore, an improved loosening device is used to improve the air permeability of the sintering material layer.

[0003] To this end, the patent specification with publication number CN206069959U discloses a loosening device for improving the gas permeability of the sintering material layer, including a loosening roller, loosening teeth, a rotating shaft, a driving system, a lifting system and a supporting platform; the loosening roller is provided with 2 to 6 rows of loosening teeth, the loosening roller is connected to the bearing fixing sleeve through the rotating shaft, and the bearing fixing sleeve is connected to the rotating driving system; the bearing fixing sleeve at the end of the loosening roller is provided with a sensor, and the lifting system is connected to the bearing fixing sleeve; the upper part of the lifting system is provided with a lifting drive system, and the lifting drive system and the lifting system are fixed on the supporting platform. This device can increase the gas permeability of the sintering mixture, optimize the distribution of fuel in the mixture, increase the output of sintered ore, and reduce the sintering solid fuel consumption. The above device has good gas permeability, but there are still some problems:

[0004] 1. Most of the loosening devices of the sintering layer have good ventilation effect, but the loosening rod may not be used when a large amount of sintering material falls.

[0005] 2. Most of the loosening devices for sintering layers have good use effects, but the loosening rods may be unstable when they are suspended in the air. Utility Model Content

[0010] When in use, the sintering material is evenly distributed on the sintering locomotive through the round roller and the nine-roller. As the sintering locomotive moves from the head to the tail of the sintering machine, it covers the entire sintering machine table. When passing through the igniter, the fuel on the upper part of the material layer is ignited and starts to burn. Under the suction force of the main exhaust fan, the sintering process from top to bottom of the material layer is completed.

The bottom end of the suspension spring is fixed with a spring ear, and the bottom end of the loosener main plate is fixed with a base spring. When started, a very strong vibration will be generated, so that the loosener main plate will drive the loosening rod to move up and down to shake off the sintered material and increase its internal air permeability.

[0012] Preferably, the suspension springs are symmetrically distributed at the top of the main plate of the loosener, the base springs are evenly distributed at the top of the fixed plate, and several base springs are designed to be fixed at the bottom end of the main plate of the loosener, so as to increase the stability and improve the vibration effect.

[0013] Preferably, the outer thread of the threaded rod is connected to an internal threaded sleeve, a first hinged seat is fixed to the top of the internal threaded sleeve, a hinged rod is hinged inside the first hinged seat, and a second hinged seat is hinged to the top of the hinged rod.

[0014] Preferably, the threaded rod is threadedly connected to the internal threaded sleeve, and the first hinge seat and the hinged rod are in an articulated structure, so that the loosening rod can still achieve the effect of loosening the sintered material when it cannot shake.

[0016] Preferably, the fixing sleeve and the limiting block are in a snap-fitting structure, and the sliding rod and the sliding sleeve are in a sliding connection, so that the loosening rod can be more stable without affecting the loosening of the material.

When a loosening rod is pressed and cannot loosen the material, it is only necessary to turn on the motor to rotate the threaded rod and drive the fixed plate to rise and fall, so that the loosening rod can still loosen the sintered material when it cannot shake, thereby realizing that the loosening rod can still loosen the material when it is pressed.

[0019] By setting up an auxiliary structure, the main plate of the loosener is designed to be connected to the suspension spring through the spring ears fixed on both sides of the top and suspended inside the limit frame, and one is installed in the middle position of the top of the main plate of the loosener. When started, it will generate very strong vibration, so that the main plate of the loosener will drive the loosening rod to move up and down to shake the sintered material, thereby increasing the air permeability inside, and a number of base springs are designed to be fixed at the bottom end of the main plate of the loosener, so that it not only increases the stability effect, but also improves the vibration effect, thereby further improving the loosening effect of the sintered material;

[0020] By setting a limiting structure, the limit block is hexagonal in design and fixed to the loosening rod, the fixing sleeve and the limit block are engaged with each other, a fixing sleeve is designed to be installed at one end of the loosening rod, and a sliding rod is fixed to the bottom end of the fixing sleeve, the limit block and the sliding sleeve are slidingly connected, a stabilizing spring is arranged inside the sliding sleeve and fixed to the bottom end of the sliding rod, and the sliding sleeve is fixed to the bottom end inside the sintering locomotive, so that when the sintering material is dropped, the loosening rod will move downward due to the pressure of the sintering material, and because the other end of the loosening rod will vibrate continuously, it will be easier for the stabilizing spring to rebound, and the loosening rod can be more stable without affecting the loosening of the material, thereby reducing the chance of the loosening rod tilting.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Embodiment 1

[0032] See also Figure 1-6 The utility model provides a loosening device for a sintering material layer, comprising a sintering locomotive 1, a limit frame 2 and a loosening device main body plate 5. The limit frame 2 is fixed inside one side of the sintering locomotive 1, nine rollers 10 are arranged at one end of the sintering locomotive 1, a baffle 4 is fixed inside one side of the limit frame 2, a loosening device main body plate 5 is arranged at the bottom end of the auxiliary structure 3, a fixed plate 6 is arranged below the loosening device main body plate 5, a loosening rod 8 is fixed inside one side of the loosening device main body plate 5, a round roller 11 is arranged above the nine rollers 10, a vibrator 12 is installed on the top of the loosening device main body plate 5, and a lifting structure 6 is arranged at the bottom end of the fixed plate 6. The lifting structure 7 comprises a threaded rod 701, an internal threaded sleeve 702, a first hinged seat 703, a hinged rod 704 and a second hinged seat 705. The threaded rod 701 is rotatably connected to the bottom end inside the limit frame 2. The outer side of the threaded rod 701 is threadedly connected to the internal threaded sleeve 702. The top of the internal threaded sleeve 702 is fixed with the first hinged seat 703. The interior of the first hinged seat 703 is hinged with the hinged rod 704. The top of the hinged rod 704 is hinged with the second hinged seat 705. The threaded rod 701 is threadedly connected to the internal threaded sleeve 702. The first hinged seat 703 and the hinged rod 704 are in a hinged structure.

[0033] The working principle of a loosening device for a sintered material layer based on Example 1 is that the threaded rod 701 is rotated by a motor and drives the internal threaded sleeve 702 to move back and forth. The loosening devices of most sintering machines use the shaking of the loosening rod 8 to prevent the sintered material from being connected all the time. However, when most of the sintered material falls down, the loosening rod 8 is suppressed, making it impossible to loosen the material. Therefore, a second hinge seat 705 is fixed to the bottom end of the fixed plate 6, and a first hinge seat 703 is fixed to the top end of the internal threaded sleeve 702, and the first hinge seat 703 and the second hinge seat 705 are hinged together through a hinge rod 704. When the threaded rod 701 rotates, the internal threaded sleeve 702 will drive the device to move up and down. When the loosening rod 8 is suppressed and cannot loosen the material, you only need to turn on the motor to make the threaded rod 701 rotate and drive the fixed plate 6 to rise and fall, so that the loosening rod 8 can still loosen the sintered material when it cannot shake.

[0034] Embodiment 2

[0035] This embodiment also includes: auxiliary structures 3 are provided at both ends of the limit frame 2, the auxiliary structures 3 include suspension springs 301, spring ears 302 and base springs 303, the suspension springs 301 are provided at both ends of the limit frame 2, the bottom end of the suspension springs 301 is fixed with spring ears 302, the bottom end of the loosener main plate 5 is fixed with base springs 303, the suspension springs 301 are symmetrically distributed at the top end of the loosener main plate 5, and the base springs 303 are evenly distributed at the top end of the fixed plate 6.

[0036] In this embodiment, one side of the suspension spring 301 is fixed on both sides of the inside of the limit frame 2, and the other side is fixed on the top of the loosening device main plate 5 through the spring ear 302. Most of the loosening devices have good use effects, but the loosening effect of some feeding devices may not be so elastic, so we design the loosening device main plate 5 to be connected with the suspension spring 301 through the spring ears 302 fixed on both sides of the top and suspended inside the limit frame 2, and a 12 is installed in the middle position of the top of the loosening device main plate 5. When 12 is started, a very strong vibration will be generated, so that the loosening device main plate 5 will drive the loosening rod 8 to move up and down to shake off the sintered material and increase the air permeability inside it. However, only having the suspension spring 301 will be a little unstable, so a number of base springs 303 are designed to be fixed on the bottom of the loosening device main plate 5, which not only increases the stability effect, but also improves the vibration effect.

[0037] Embodiment 3

[0038] This embodiment also includes: a limiting structure 9 is provided on one side of the loosening rod 8, and the limiting structure 9 includes a fixed sleeve 901, a limit block 902, a slide rod 903, a stabilizing spring 904 and a sliding sleeve 905. The fixed sleeve 901 is installed on one side of the loosening rod 8, and the interior of the fixed sleeve 901 wraps the limit block 902. The bottom end of the fixed sleeve 901 is fixed with a slide rod 903, and the bottom end of the slide rod 903 is fixed with a stabilizing spring 904. The outer side of the stabilizing spring 904 is provided with a sliding sleeve 905. The fixed sleeve 901 and the limit block 902 are in a snap-fitting structure, and the slide rod 903 and the sliding sleeve 905 are in a sliding connection.

[0039] In this embodiment, the limit block 902 is hexagonal in design and fixed with the loosening rod 8, and the fixing sleeve 901 and the limit block 902 are engaged with each other. Most of the loosening devices loosen the sintered material by shaking the loosening rod 8 to increase the air permeability inside. However, since the loosening rod 8 of the upper part of the device is 30 cm shorter than the loosening rod 8 of the lower part, the rear part of the loosening rod 8 of the device is suspended, so that when the sintered material is dropped, the loosening rod 8 may be tilted. Therefore, in order to reduce the occurrence of this problem, we design a fixing sleeve 901 to install A slide bar 903 is installed at one end of the loosening rod 8, and the bottom end of the fixed sleeve 901 is fixed with the slide bar 903, the limit block 902 is slidably connected with the slide sleeve 905, a stabilizing spring 904 is arranged inside the slide sleeve 905 and is fixed to the bottom end of the slide bar 903, and the slide sleeve 905 is fixed to the bottom end inside the sintering locomotive 1, so that when the sintering material is dropped, the loosening rod 8 will move downward due to the pressure of the sintering material, and because the other end of the loosening rod 8 will vibrate continuously, it will be easier for the stabilizing spring 904 to rebound, and the loosening rod 8 will be more stable without affecting the loosening of the material.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
