Description

Technical Field

[0001] This utility model relates to the field of sintering metallurgical equipment technology, and in particular to an energy-saving sintering high-efficiency combustion-supporting and gas-permeable device. Background Technology

[0002] Sintering generally refers to the process of bonding solid particles together at high temperatures, causing grain growth, reducing porosity (pores) and grain boundaries, and through mass transfer, resulting in volume shrinkage, increased density, and ultimately a dense polycrystalline sintered body with a specific microstructure. Commonly used sintering equipment includes belt sintering machines, pusher kilns, and tunnel kilns. The sintering process includes steps such as raw material preparation, forming, sintering, and cooling. During sintering, parameters such as atmosphere, temperature, and time must be strictly controlled to obtain the desired microstructure and properties.

[0003] Chinese patent document CN202021860915.7 discloses a sintering permeability device, which can improve the permeability of the sintering process and improve the sintering effect. This utility model includes a support frame, a permeability mechanism, and a height adjustment mechanism. The permeability mechanism is mounted on a machine frame. The support frame spans the sintering zone to be processed. Diagonal braces are provided on both sides of the support frame. Each diagonal brace is equipped with a height adjustment mechanism. The height adjustment device includes a hydraulic cylinder, a push rod, and a support roller. The base of the hydraulic cylinder is fixed to the diagonal brace. The piston rod of the hydraulic cylinder pushes against the push rod and moves along the diagonal brace. The support roller spans across the diagonal braces on both sides of the machine frame and contacts the push rod. The support roller supports the permeability mechanism and adjusts the position and height of the working end of the permeability mechanism. This utility model is simple, practical, reliable, and stable, applicable to both large and small sintering machines, and improves production efficiency.

[0004] However, the above-mentioned patent has certain defects in use. During the sintering process, since the sintering material is solid particles, when the venting device of the device is perforated, it will cause the sintering material to loosen. This will cause some raw materials to diffuse and fly during the exhaust sintering process, thereby reducing the sintering quality and causing pollution to the working environment.

[0005] To address these issues, an energy-saving sintering high-efficiency combustion-supporting and permeable device is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology and solve the problem that the material will loosen and spread after the material is punched on the sintering trolley, this utility model provides an energy-saving sintering high-efficiency combustion-supporting and air-permeable device.

[0007] This utility model is achieved using the following technical solution:

[0008] An energy-saving sintering high-efficiency combustion-supporting and ventilation device includes a workbench and support legs. The support legs are provided in four places and are respectively fixed around the lower end of the workbench. The upper end of the workbench is provided with a mounting seat, which is fixed on the workbench. There are two mounting seats, and ventilation devices are provided on the mounting seats. The ventilation devices are used to puncture and ventilate the material on the sintering trolley.

[0009] The ventilation device includes a rotating shaft that passes through the mounting bases. Keys are provided at both ends of the rotating shaft and are integrated with the rotating shaft. Rotating frames are provided on both sides of the rotating shaft. Mounting rings are provided at both ends of the rotating frames and are integrated with the rotating frames. One end of the rotating frame passes through the rotating shaft, and the other end is provided with a rotating roller.

[0010] The rotating roller is provided with multiple ventilation rods, which are evenly and equidistantly fixed on the rotating roller. The rotating roller is rotatably connected to the mounting ring through shaft pins on both sides, and a limiting block is provided on the outer wall of the shaft pin.

[0011] Spray pipes are provided between the rotating frames. The spray pipes are fixed to the rotating frames by mounting plates. The lower surface of the spray pipes is provided with multiple spray heads, and the upper surface of the spray pipes is provided with water inlets.

[0012] A pressure roller is also provided between the rotating frames. The axis of the pressure roller is on the same horizontal line as the axis of the rotating roller. The pressure roller is rotatably mounted between the rotating frames via a pivot pin.

[0013] The end of the venting rod is provided with an external thread, and the venting rod is threadedly connected to the rotating roller.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. By setting pressure rollers and spray pipes on the side of the ventilation device, the spray pipes can pre-wet the material, increase the adhesion and weight between the materials, thereby reducing the flying of the material after punching, while the pressure rollers can slightly compact the material, further suppressing the flying of the material.

[0016] 2. The threaded connection between the venting rod and the rotating roller allows the venting rod to be replaced. This design enables the device to adapt to various material types and sintering process requirements, thus enhancing the device's applicability. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an energy-saving sintering high-efficiency combustion-supporting and ventilating device includes a workbench 1 and support legs 2. Four support legs 2 are provided, respectively fixed around the lower end of the workbench 1 to ensure stability and prevent shaking or tilting during operation. The workbench 1 serves as the basic support platform for the entire device, placed above the sintering trolley to ensure sufficient and stable operating space. An mounting base 32 is provided at the upper end of the workbench 1 for mounting the ventilating device. Two mounting bases 32 are provided, each equipped with a ventilating device for perforating and ventilating the material on the sintering trolley.

[0025] The ventilation device includes a rotating shaft 3, which is inserted between mounting bases 32. Keys 31 are provided at both ends of the rotating shaft 3. The keys 31 are integrated with the rotating shaft 3. The design of the keys 31 facilitates power transmission. When the rotating shaft 3 rotates, the rotating frame 7 will also rotate. Rotating frames 7 are provided on both sides of the rotating shaft 3. Mounting rings 71 are provided at both ends of the rotating frame 7. The mounting rings 71 are integrated with the rotating frame 7. One end of the rotating frame 7 is inserted on the rotating shaft 3, and the other end is provided with a rotating roller 6.

[0026] The rotating roller 6 is provided with a plurality of ventilation rods 61, which are evenly and equidistantly fixed on the rotating roller 6. These ventilation rods 61 are used to puncture and ventilate the material on the sintering trolley. The rotating roller 6 is rotatably connected to the mounting ring 71 by the shaft pins on both sides. The outer side wall of the shaft pin is provided with a limiting block 63, which is located outside the rotating frame 7 to ensure that the rotating roller 6 rotates stably within a certain range without falling off.

[0027] Spray pipes 4 are provided between the rotating frames 7. The spray pipes 4 are fixed to the rotating frames 7 by mounting plates 42. The lower surface of the spray pipes 4 is provided with multiple spray heads 43. The spray heads 43 spray water mist evenly onto the surface of the material to pre-wet the material. The upper surface of the spray pipes 4 is provided with a water inlet 41, which is connected to an external water source to provide water to the spray pipes 4.

[0028] A pressure roller 5 is also provided between the rotating frames 7. The axis of the pressure roller 5 is on the same horizontal line as the axis of the rotating roller 6. The pressure roller 5 is used to slightly compact the material after the ventilation rod 61 is punched. The pressure roller 5 is rotatably installed between the rotating frames 7 through a shaft pin.

[0029] The end of the ventilating rod 61 is provided with an external thread 62. The ventilating rod 61 is threadedly connected to the rotating roller 6. The ventilating rod 61 adopts a threaded connection, which facilitates the replacement or adjustment of the length and density of the ventilating rod 61 to adapt to the ventilation requirements of different materials.

[0030] The working principle of this utility model is as follows: When in use, place the workbench 1 in the designated position above the material on the sintering trolley, ensuring that the material is evenly spread on the trolley, and connect the water source to the inlet 41 of the spray pipe 4 to prepare for pre-wetting treatment.

[0031] At the same time, the spray pipe 4 receives water through the water inlet 41, and the water mist is evenly sprayed onto the surface of the material from the spray head 43 to achieve pre-wetting treatment. Pre-wetting not only helps to release gas in the material, but also increases the stickiness and weight between materials, preparing for the subsequent air permeation process.

[0032] The trolley moves on the guide rail, and at this time the rotating roller 6 rotates on the rotating frame 7. The air-permeable rod 61 on the rotating roller 6 rotates with the rotating roller 6, and the material is evenly perforated and ventilated. The design of the air-permeable rod 61 makes the perforation process stable and uniform, and improves the air permeability of the material.

[0033] After the ventilation rod 61 is punched, the pressure roller 5 lightly compacts the material. The axis of the pressure roller 5 is on the same horizontal line as the axis of the rotating roller 6. It is rotatably installed between the rotating frame 7 through the shaft pin to ensure that the compaction process is stable and uniform. Light compaction helps to further promote gas flow and improve ventilation efficiency. It also helps the material to burn stably during the sintering process and further suppresses the scattering of the material.

[0034] After the permeability and slight compaction are completed, the sintering trolley enters the sintering chamber for sintering. Due to the improved permeability of the material, the gas exchange during the sintering process is more complete, and the combustion efficiency is improved.

[0035] Clean workbench 1 and the ventilation device to prepare for the next round of sintering.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
