Description

Technical Field

[0001] This utility model relates to the field of storage bin technology, specifically to a storage bin for lining material of a medium-frequency furnace. Background Technology

[0002] After the furnace lining material is produced, it needs to be stored in a storage silo. When it needs to be packaged, the furnace lining material needs to be discharged from the storage silo into the packaging bag. When a packaging bag is full of furnace lining material, the valve needs to be manually closed or the electronic valve needs to be closed using a controller. This means that the valve needs to be opened and closed frequently during the packaging process. If the valve is opened and closed manually, the process is cumbersome. If the electronic valve is opened and closed using a controller, an additional controller is required. It is impossible to achieve periodic intermittent discharge of furnace lining material without manual control or controller operation of the valve. Summary of the Invention

[0003] The purpose of this invention is to address the problem in existing technologies that cannot achieve periodic and intermittent discharge of furnace lining material without manual control or valve manipulation by a controller, and to provide a medium-frequency furnace lining material storage bin.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a medium-frequency furnace lining storage bin, comprising a bin body, a motor installed at the bottom of the bin body, the motor being connected to and driving a gear via a rotating shaft, a turntable attached to and rotatably connected to the bottom of the bin body, gear discs meshing with the gears being installed around the turntable, a plurality of arc-shaped holes being formed on the turntable, the plurality of arc-shaped holes forming a virtual ring, and a plurality of material discharge ports being formed at the bottom of the bin body, the distribution positions of the plurality of material discharge ports corresponding to the movement trajectory of the arc-shaped holes.

[0005] In the above scheme, the inside of the silo is used for material storage. When the arc-shaped hole and the discharge port are separated, the discharge port is blocked by the turntable, thereby preventing the furnace lining material from falling out of the discharge port. After the furnace lining material enters the silo, it can accumulate inside the silo.

[0006] When it is necessary to discharge the furnace lining material from the silo, the motor is started. The motor drives the gear to rotate, and the gear drives the gear plate and turntable to rotate. As the turntable rotates, the overlapping part of the arc-shaped hole and the discharge port changes continuously. When the arc-shaped hole and the discharge port are connected, the furnace lining material can fall out through the discharge port, thus realizing the discharge of the furnace lining material.

[0007] When the arc-shaped hole rotates to a position separated from the material discharge port, the furnace lining material stops being discharged. Workers use this gap to remove the packaging bag containing the furnace lining material, replace the empty furnace lining material, and wait for the next discharge. This eliminates the need for manual or controller-controlled valve rotation and closure.

[0008] Preferably, the number of arc-shaped holes is a positive integer multiple of the material discharge port, and the multiple arc-shaped holes are distributed at equal angular intervals, and the multiple material discharge ports are distributed at equal angular intervals.

[0009] In the above scheme, when one discharge port is connected to any arc-shaped hole, the other discharge ports can also be connected to the corresponding arc-shaped holes, thus ensuring that multiple discharge ports discharge material at the same time.

[0010] Preferably, a T-shaped slider is installed on the top of the turntable, and an annular groove is provided at the bottom of the chamber for the T-shaped slider to slide.

[0011] In the above scheme, the T-shaped slider sliding in the annular groove can limit the turntable, allowing it to rotate around the center. At the same time, the T-shaped slider installed in the annular groove can hold the turntable in place, preventing it from falling.

[0012] Preferably, the bottom of the hopper is fitted with a mounting box via a connecting plate, and the motor is installed inside the mounting box.

[0013] In the above scheme, the mounting box can protect the motor, thereby preventing furnace lining material from entering the motor.

[0014] Preferably, the top end of the rotating shaft is rotatably connected to the bottom of the chamber body via a bearing seat.

[0015] In the above scheme, the shaft can be supported and rotated stably by rotating within the bearing housing.

[0016] Preferably, a discharge hopper is detachably installed at the bottom of the hopper, and the motor and the turntable are located inside the discharge hopper;

[0017] The discharge hopper is equipped with multiple ear plates, which are bolted to the hopper body.

[0018] In the above scheme, the discharge hopper can collect the furnace lining material falling from multiple discharge ports, so that the furnace lining material falls from the bottom of the discharge hopper, thereby changing the single-point discharge from the discharge port to the single-point discharge from the discharge hopper. The bottom of the bin body is provided with multiple threaded holes for bolt thread connection. After the bolt passes through the through hole of the ear plate, it is threaded into the threaded hole. The discharge hopper is detachably installed at the bottom of the bin body, which can realize the switching between single-point discharge and multi-point discharge of furnace lining material.

[0019] Preferably, the top side of the silo body is provided with a feed inlet.

[0020] In the above scheme, the feed port is used to facilitate the addition of furnace lining material into the silo body.

[0021] Preferably, the hopper body is equipped with a plurality of support legs for supporting the hopper body.

[0022] In the above scheme, the support legs can support the hopper body, thus facilitating the installation of the discharge hopper.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The medium-frequency furnace lining storage bin, driven by a motor, has an arc-shaped hole that periodically connects and isolates with the material discharge port, thereby achieving periodic intermittent discharge of the furnace lining material. When the bin is discharging material, the furnace lining material is stored in a packaging bag. When the bin is not discharging material, the staff can use the gaps in discharging to change the packaging bag for refilling.

[0025] 2. In this medium-frequency furnace lining storage bin, the number of arc-shaped holes is a positive integer multiple of the number of material discharge ports. Multiple arc-shaped holes are distributed at equal angular intervals, and multiple material discharge ports are distributed at equal angular intervals. When a material discharge port is connected to any arc-shaped hole, other material discharge ports can also be connected to the corresponding arc-shaped holes, thereby ensuring that multiple material discharge ports discharge material simultaneously.

[0026] 3. When multiple discharge points are required for the lining material storage bin of this medium-frequency furnace, multiple discharge points can be used to discharge the lining material, allowing it to fall into multiple packaging bags, thereby improving the discharge efficiency of the lining material. When single-point discharge is required, the discharge hopper can be installed at the bottom of the bin body to discharge the material at a single point, thus enabling the device to switch between multi-point discharge and single-point discharge.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Please refer to Figures 1 to 5 In this embodiment, a medium-frequency furnace lining storage bin includes a bin body 1. A motor 2 is installed at the bottom of the bin body 1. The motor 2 is connected to and drives a gear 4 via a rotating shaft 3. A turntable 5 is attached to and rotatably connected to the bottom of the bin body 1. Gear discs 6 that mesh with the gear 4 are installed around the turntable 5. Multiple arc-shaped holes 7 are opened on the turntable 5. The multiple arc-shaped holes 7 together form a virtual ring. Multiple material discharge ports 8 are opened at the bottom of the bin body 1. The distribution positions of the multiple material discharge ports 8 correspond to the movement trajectory of the arc-shaped holes 7.

[0035] In the above scheme, the inside of the silo 1 is used for material storage. When the arc-shaped hole 7 and the discharge port 8 are separated, the discharge port 8 is blocked by the turntable 5, thereby preventing the furnace lining material from falling out of the discharge port 8. After the furnace lining material enters the silo 1, it can accumulate inside the silo 1.

[0036] When it is necessary to discharge the furnace lining material from the bin 1, the motor 2 is started. The motor 2 can drive the gear 4 to rotate. The gear 4 drives the gear plate 6 and the turntable 5 to rotate. As the turntable 5 rotates, the overlapping part of the arc-shaped hole 7 and the discharge port 8 is constantly changing. When the arc-shaped hole 7 and the discharge port 8 are connected, the furnace lining material can fall out through the discharge port 8, realizing the discharge of the furnace lining material.

[0037] When the arc-shaped hole 7 rotates to be separated from the material discharge port 8, the furnace lining material will no longer be discharged. The staff can use this gap to remove the packaging bag containing the furnace lining material, replace the empty furnace lining material, and wait for the next discharge. This eliminates the need for manual or controller control of the valve opening and closing.

[0038] By driving the turntable 5 to rotate via the motor 2, the overlapping position of the arc-shaped hole 7 and the material discharge port 8 on the turntable 5 can be continuously changed, so that the furnace lining material at different positions in the arc-shaped hole 7 can fall out through the material discharge port 8, thereby avoiding the problem that all the furnace lining material above the material discharge port 8 falls out while the furnace lining material around the material discharge port 8 cannot fall out under the action of gravity.

[0039] It should be noted that the ratio of the discharge time to the non-discharge time in bin 1 during each cycle can be controlled by the length of the arc-shaped hole 7. The longer the arc-shaped hole 7 is, the greater the ratio of the discharge time to the non-discharge time. The duration of the entire cycle can be controlled by controlling the rotation speed of the output shaft of motor 2. When the output shaft of motor 2 rotates faster, the entire cycle is shorter, and when the output shaft of motor 2 rotates slower, the entire cycle is longer. Setting the turntable 5 to fit snugly against the bottom of bin 1 can prevent the furnace lining material from entering between the turntable 5 and bin 1 during the material dropping process.

[0040] In this embodiment, the number of arc-shaped holes 7 is a positive integer multiple of the material discharge ports 8. Multiple arc-shaped holes 7 are distributed at equal angular intervals, and multiple material discharge ports 8 are distributed at equal angular intervals. When a material discharge port 8 is connected to any arc-shaped hole 7, other material discharge ports 8 can also be connected to the corresponding arc-shaped hole 7, thereby ensuring that multiple material discharge ports 8 discharge material at the same time.

[0041] For example, there are two material discharge ports 8 and two arc-shaped holes 7. The two material discharge ports 8 are distributed at 180° intervals, and the two arc-shaped holes 7 are distributed at 180° intervals. Since the two material discharge ports 8 and the two arc-shaped holes 7 are distributed at 180° intervals, when one arc-shaped hole 7 is connected to any one material discharge port 8, the other arc-shaped hole 7 is also connected to the other material discharge port 8 at the same time. This allows the two material discharge ports 8 to discharge material at the same time, and can fill multiple packaging bags at the same time.

[0042] For example, when there are four arc-shaped holes 7 and two material discharge ports 8, the four arc-shaped holes 7 are distributed at 90° intervals. When one arc-shaped hole 7 is connected to any one of the material discharge ports 8, the arc-shaped hole 7 that is 180° apart from this arc-shaped hole 7 can be connected to another material discharge port 8, and the two material discharge ports 8 can also be connected to discharge material at the same time.

[0043] In this embodiment, a T-shaped slider 9 is installed on the top of the turntable 5, and an annular groove 10 for the T-shaped slider 9 to slide is provided at the bottom of the chamber 1.

[0044] In the above scheme, the T-shaped slider 9 can slide in the annular groove 10 to limit the turntable 5, so that the turntable 5 can rotate around the center. At the same time, the T-shaped slider 9 installed in the annular groove 10 can hold the turntable 5 and prevent the turntable 5 from falling.

[0045] In this embodiment, the bottom of the silo body 1 is equipped with a mounting box 12 via a connecting plate 11. The motor 2 is installed inside the mounting box 12. The top of the rotating shaft 3 is rotatably connected to the bottom of the silo body 1 via a bearing seat. A feed inlet is provided on the top side of the silo body 1. A feed pipe 15 is installed on the feed inlet. A pipe cover 16 is installed on the feed pipe 15. Multiple support legs 14 are installed on the silo body 1 to support the silo body 1.

[0046] In the above scheme, the mounting box 12 can protect the motor 2, thereby preventing the furnace lining material from entering the motor 2. The mounting box 12 is provided with a ventilation port, and a filter screen is installed in the ventilation port. The ventilation port can ventilate and dissipate heat for the motor 2. The filter screen can prevent the furnace lining material from entering the mounting box 12 through the ventilation port. The rotating shaft 3 rotates in the bearing seat, which can support the rotating shaft 3 and make it rotate stably. The feed port is used to facilitate the addition of the furnace lining material into the bin 1. The feed pipe 15 can guide the furnace lining material. The pipe cover 16 can seal the bin 1, thereby preventing rainwater from entering the bin 1.

[0047] In this embodiment, a discharge hopper 13 is detachably installed at the bottom of the hopper 1, and the motor 2 and turntable 5 are located inside the discharge hopper 13.

[0048] Multiple ear plates 17 are installed on the discharge hopper 13, and the ear plates 17 are installed on the bin body 1 by bolts 18.

[0049] In the above scheme, the discharge hopper 13 can collect the furnace lining material falling from multiple discharge ports 8, so that the furnace lining material falls from the bottom of the discharge hopper 13, thereby changing the single-point discharge of the discharge port 8 to the single-point discharge of the discharge hopper 13. The bottom of the bin 1 is provided with multiple threaded holes for bolts 18 to be threaded. The bolts 18 pass through the through holes of the ear plate 17 and are threaded into the threaded holes. The discharge hopper 13 is detachably installed at the bottom of the bin 1, which can realize the switching between single-point discharge and multi-point discharge of the furnace lining material.

[0050] Operating procedure: When single-point discharge is required using the discharge port 8, place the packaging bag with its opening open below the discharge port 8. Start motor 2. The output shaft of motor 2 rotates, driving shaft 3 to rotate. Shaft 3 drives gear 4 to rotate, which in turn drives turntable 5 to rotate via gear disc 6. Turntable 5 causes T-shaped slider 9 to slide within annular groove 10. When the arc-shaped hole 7 on turntable 5 connects with the discharge port 8, the furnace lining material falls out from the arc-shaped hole 7 and the discharge port 8. When the arc-shaped hole 7 is separated from the discharge port 8, the packaging bag is exactly full. For furnace lining material, the workers remove the packaging bags filled with furnace lining material and replace them with packaging bags that are not filled with furnace lining material. They wait for the arc-shaped hole 7 to rotate again to connect with the discharge port 8 before discharging the material, thus achieving periodic intermittent discharge of the furnace lining material. When single-point discharge of the furnace lining material is required, the discharge hopper 13 is placed against the bottom of the silo body 1, and the bolt 18 is threaded into the threaded hole after passing through the through hole of the ear plate 17, thus installing the discharge hopper 13. This allows the furnace lining material to fall from the discharge port 8 and be discharged through the discharge hopper 13, achieving single-point discharge of the furnace lining material.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
