[0001] The utility model relates to the technical field of metallurgical solid waste, in particular to a magnetic attraction moving device of a kiln car. Background Art

[0002] The production of reduced iron powder uses iron oxide scale or high-purity iron concentrate powder produced in the steel rolling process as raw materials, and solid carbon (coke powder or low-sulfur anthracite) as a reducing agent. The reducing agent and iron oxide scale powder are charged into a silicon carbide refractory tank in a concentric circle distribution method. Driven by the kiln car, it is sent to the tunnel kiln for high-temperature reduction to form sponge iron, and then refined through crushing, secondary reduction, powder cake crushing, screening, batching and other processes.

[0003] After the silicon carbide refractory tank is pulled out of the tunnel kiln, the unloading operation is carried out through the equipment above the operating platform. The unloading section includes lifting the cover, cleaning the reducing agent in the inner chamber, pulling out the reduced iron, cleaning the reducing agent in the outer chamber, and then the loading operation is carried out through the equipment above the operating platform. The loading section includes placing the mold, loading the reducing agent in the inner chamber, loading the iron oxide powder, loading the reducing agent in the outer chamber, and buckling the cover. The kiln car needs to stop 9 times during the whole unloading and loading process. Traditionally, each kiln car is connected to each other and moved by the winch. Since the operation time of each section is different, it cannot be guaranteed that the parking position and parking time of each kiln car meet the requirements of the corresponding section, resulting in low work efficiency.

Based on the embodiments 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.

[0018] like Figure 1-2 As shown, the magnetic attraction moving device of the kiln car includes a slide rail 1, a sliding trolley 3, a motor 5, a reducer 6, a wire trough 21, and an electromagnet assembly 7;

[0019] The slide rail 1 is arranged parallel to the operating platform 2, and a plurality of sliding trolleys 3 are slidably provided on the slide rail 1. The plurality of sliding trolleys 3 are arranged one by one corresponding to each working section 4 of the operating platform 2. A motor 5, a reducer 6, and an electromagnet assembly 7 are fixed in sequence at the top of the sliding trolley 3 along its moving direction.

[0020] The function of the electromagnet assembly 7 is to fix the kiln car 8 of the corresponding section 4 when the electromagnet 7.2 is energized, and the kiln car 8 is driven to move along the kiln car track 9 under the drive of the motor 5. At the same time, the moving distance of the kiln car 8 in the section 4 is controlled by starting and stopping the motor 5. The silicon carbide refractory tanks 10 loaded on the kiln car 8 are arranged in rows. When the first row of silicon carbide refractory tanks 10 on the kiln car 8 reaches the operating port 11 of the operating platform 2, the operating device on the top of the operating platform 2 probes down through the operating port 11. After completing the corresponding operation, the motor 5 is started, and the kiln car 8 moves forward by a row of silicon carbide refractory tanks 10, which controls the kiln car 8. A row of silicon carbide refractory tanks 10 are arranged on and below the car 8 to operate the section 4. Each section 4 has an operator who only needs to control the motor 5 and equipment of his section 4, thereby reducing misoperation and simplifying the difficulty of operation. The moving range of the kiln car 8 can be accurately controlled. Each section of the kiln car 8 is independently arranged. The time and parking position of each kiln car 8 in each section 4 do not interfere with each other and do not affect each other. The work efficiency is high. Even if the previous section 4 is slow and the next section 4 is fast, the kiln car 8 of the next section 4 only needs to stop and wait, and the controllability is high.

[0021] The top of the sliding trolley 3 between the reducer 6 and the electromagnet assembly 7 is rotatably connected with a rotating shaft 12 through a bearing seat. The rotating shaft 12 is arranged perpendicular to the moving direction of the sliding trolley 3. The output end of the motor 5 is transmission-connected to the output end of the reducer 6. The output end of the reducer 6 is transmission-connected to the rotating shaft 12. The specific transmission connection method is chain transmission. A driving gear 13 is fixedly connected to the rotating shaft 12, and the driving gear 13 is meshed with the rack 14 at the top of the slide rail 1.

[0022] The electromagnet assembly 7 comprises a shell 7.1, an electromagnet 7.2, a guide rod 7.3 and a sliding rod 7.4. The electromagnet 7.2 is slidably arranged inside the shell 7.1. An opening 15 matching the electromagnet 7.2 is provided on one side of the shell 7.1. Two sliding rods 7.4 are fixed on the other side of the shell 7.1. A first positioning block 16 is fixed on the end of the sliding rod 7.4. A support plate 17 is slidably arranged between the two sliding rods 7.4. A spring 18 is sleeved on the sliding rod 7.4 between the support plate 17 and the shell 7.1. Two guide rods 7.3 are movably penetrated on the support plate 17 between the two sliding rods 7.4. One end of the guide rod 7.3 penetrates the shell 7.1 and is fixedly connected to the outer wall of the electromagnet 7.2. A second positioning block 19 is fixed on the other end of the guide rod 7.3.

[0023] After the electromagnet 7.2 is energized, it moves toward the kiln car 8 under the action of the sliding rod 7.4 and the guide rod 7.3 until it sucks the outer wall of the kiln car 8, so that the sliding trolley 3 and the kiln car 8 are connected as a whole. Under the driving action of the motor 5, the sliding trolley 3 drives the kiln car 8 to move. When the silicon carbide refractory tanks 10 on the entire kiln car 8 complete the operation of the section 4, the sliding trolley 3 moves to the rear end of the section 4, and the electromagnet 7.2 is powered off. Under the action of the elastic force of the spring 18, the electromagnet 7.2 moves away from the kiln car 8, and the motor 5 is reversed. Under the action of the motor 5, the sliding trolley 3 moves to the front end of the section 4, and the next kiln car 8 can be moved into the section 4.

[0024] A vertically arranged bracket 20 is fixed to the top of the sliding trolley 3, and a wire trough 21 is fixed to the top of the bracket 20. The other end of the wire trough 21 is connected to the wiring port 22 of the operating platform 2. Above the operating platform 2 is equipment that cooperates to complete the operation of each work section 4. The power supply used by the equipment is used to power the magnetic suction moving device of each work section 4 using the wire trough 21, specifically including power supply for the motor 5 and the electromagnet 7.2.

[0025] The specific operation process of this embodiment is as follows:

[0026] Each section 4 is provided with a magnetic attraction moving device. When the kiln car 8 arrives at the corresponding section 4, the corresponding magnetic attraction moving device is started to attract the outer wall of the kiln car 8 through the electromagnet assembly 7, and the motor 5 and the reducer 6 are started. The reducer 6 drives the driving gear 13 to rotate, and the driving gear 13 is meshed with the rack 14, driving the sliding trolley 3 to slide along the slide rail 1;

[0027] The kiln car 8 is equipped with multiple rows of silicon carbide refractory tanks 10. When one row of silicon carbide refractory tanks 10 is operated on the section 4, the motor 5 is started to move the kiln car 8 forward by the distance of one row of silicon carbide refractory tanks 10, and the operation of the section 4 is performed on the next row of silicon carbide refractory tanks 10;

[0028] Each section 4 controls a single motor 5, and each kiln car 8 is not related to each other, so that each section 4 has a corresponding kiln car 8 to perform corresponding operations, thereby improving production efficiency;

[0029] After the operation of the kiln car 8 of the current section 4 is completed, the electromagnet assembly 7 of the magnetic attraction moving device of the section 4 loses power, the kiln car 8 is released, and the magnetic attraction moving device of the next section 4 moves to the position of the kiln car 8 to fix it, and this cycle repeats until the operation of all sections 4 is completed and the winch is used to move it into the tunnel kiln.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
