Description

Technical Field

[0001] This utility model relates to the field of steel smelting equipment technology, and in particular to an effective and energy-saving blast furnace smelting additive conveying device. Background Technology

[0002] In the iron and steel smelting industry, blast furnace smelting is a key step in converting additives such as iron ore, coke, and limestone into molten iron. The additives usually need to be transported from the storage area to the blast furnace feed port by a conveying device. This process faces the following technical challenges.

[0003] The temperature of blast furnace feed can reach 200-500℃. When traditional belt conveyors are in continuous contact with high-temperature materials, the conveyor belt is prone to aging, deformation or even breakage, resulting in frequent replacement of equipment parts, increased maintenance costs and downtime. The viscosity of high-temperature materials increases, making them easy to adhere to the surface of the conveyor belt, causing material to slip or the conveying volume to be unstable. At the same time, the high-temperature environment may also cause the conveyor belt drive system to malfunction, affecting the overall production process.

[0004] In existing technologies, some conveying devices use spray water for cooling, but the wastewater is discharged directly without recycling, resulting in a large waste of water resources. According to statistics, a medium-sized blast furnace can convey and add thousands of tons of material per day. If a non-circulating cooling system is used, the daily water consumption can reach tens of tons. In addition, high-temperature materials will generate dust, particles and other impurities during the conveying process. After being mixed into the cooling water, they can easily clog the nozzles, water pumps and pipes, resulting in a decrease in cooling effect and requiring frequent shutdowns for cleaning and maintenance.

[0005] Therefore, how to provide an effective and energy-saving blast furnace smelting additive conveying device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide an effective and energy-efficient blast furnace smelting feed conveying device. This invention utilizes cooling nozzles installed inside the conveyor belt to provide real-time cooling of high-temperature materials and the conveyor belt, preventing damage due to high-temperature aging. Simultaneously, a closed-loop water circulation system is constructed using a collection tray, recovery pipe, and water tank to filter and reuse the cooled wastewater, significantly reducing water consumption and operating costs. Furthermore, the detachable filter plates and shock-absorbing support legs further enhance the device's ease of maintenance and operational stability, contributing to efficient and energy-saving production in the steel smelting industry.

[0007] An efficient and energy-saving blast furnace smelting additive conveying device according to an embodiment of the present invention includes a conveyor frame and a water tank. A conveyor belt is installed inside the conveyor frame. A bracket is fixedly installed on one side of the bottom of the conveyor frame. The water tank is fixedly installed at the bottom of the conveyor frame via the bracket. Several sets of collection trays are fixedly installed on the inner wall of the conveyor frame and inside the conveyor belt. A branch pipe is installed on the inner wall of the conveyor frame and above each set of collection trays. Several sets of cooling nozzles are installed on the top of the branch pipe. A water outlet is provided at the front end of each collection tray. A recovery pipe is installed on the side wall of the conveyor frame and connected to each set of water outlets. The end of the recovery pipe is inserted into the water tank. A water supply pipe is provided on the side wall of the conveyor frame and above the recovery pipe. Each set of branch pipes is connected to the water supply pipe. The end of the water supply pipe is located inside the water tank.

[0008] Furthermore, a water pump is installed inside the water tank, and the water delivery pipe is connected to the output end of the water pump built into the water tank.

[0009] Furthermore, rollers are provided at both ends of the inner side of the conveyor frame, and the conveyor belt is sleeved and installed on the two sets of rollers.

[0010] Furthermore, a filter plate is detachably installed inside the collection tray, and one side of the filter plate extends through the conveyor frame, with a filter screen installed inside the filter plate.

[0011] Furthermore, the inner wall of the collection tray has a slot, and the filter plate is inserted into the slot.

[0012] Furthermore, a handle is provided at one end of the filter plate, and one side of the handle is located outside the conveyor frame.

[0013] Furthermore, a drive motor is fixedly installed on the side wall of the conveyor frame, near the roller, and the drive motor is connected to the roller on one side for transmission.

[0014] Furthermore, a water inlet is provided on one side of the top of the water tank, and a dust cover can be detachably installed on the water inlet.

[0015] Furthermore, several sets of support legs are fixedly installed at the bottom of the conveyor frame, and the sets of support legs are equidistantly distributed at the bottom of the conveyor frame.

[0016] The beneficial effects of this utility model are:

[0017] 1. The circulating cooling system composed of a water tank, water supply pipe, branch pipe and cooling nozzles in this utility model can cool the high-temperature blast furnace feed and conveyor belt in real time. The cooling nozzles are evenly distributed on the inner side and above the conveyor belt. The sprayed water mist directly acts on the high-temperature material and the surface of the conveyor belt, effectively reducing the operating temperature of the conveyor belt, avoiding aging, deformation or breakage of the conveyor belt caused by long-term high temperature, and significantly extending the service life of the equipment.

[0018] 2. The detachable filter plate and filter screen design inside the collection tray of this utility model can effectively intercept dust, particles and other impurities in the cooling wastewater, prevent impurities from clogging the nozzles or water pumps, ensure the long-term stable operation of the water circulation system, and is more energy-efficient. The filter plate and the collection tray are connected by a slot, and the filter screen can be cleaned by easily pulling out the filter plate with the handle, which has low maintenance costs and is easy to operate.

[0031] like Figure 1-6 As shown, this utility model discloses an effective and energy-saving blast furnace smelting additive conveying device, including a conveyor frame 1 and a water tank 5. A conveyor belt 2 is installed inside the conveyor frame 1. A bracket 9 is fixedly installed on one side of the bottom of the conveyor frame 1. The water tank 5 is fixedly installed at the bottom of the conveyor frame 1 through the bracket 9. Several sets of collection trays 12 are fixedly installed on the inner wall of the conveyor frame 1 and inside the conveyor belt 2. A branch pipe 13 is installed on the inner wall of the conveyor frame 1 and above each set of collection trays 12. Several sets of cooling nozzles 14 are installed on the top of the branch pipe 13. A water outlet 16 is provided at the front end of the collection tray 12. A recovery pipe 4 is installed on the side wall of the conveyor frame 1 and connected to each set of water outlets 16. The end of the recovery pipe 4 is inserted into the water tank 5. A water supply pipe 3 is provided on the side wall of the conveyor frame 1 and above the recovery pipe 4. Each set of branch pipes 13 is connected to the water supply pipe 3. The end of the water supply pipe 3 is located in the water tank 5.

[0032] It is worth noting that a water pump is installed inside the water tank 5, and the water supply pipe 3 is connected to the output end of the water pump inside the water tank 5. This structural design allows the water in the water tank 5 to be transported to the water supply pipe 3 by the water pump, and then distributed to each branch pipe 13 through the water supply pipe 3, and finally sprayed out from the cooling nozzle 14 to achieve the cooling treatment of the conveyor belt 2 and the additives.

[0033] Rollers 10 are installed at both ends of the inner side of the conveyor frame 1, and the conveyor belt 2 is sleeved on the two sets of rollers 10. A drive motor 8 is fixedly installed on the side wall of the conveyor frame 1, close to the rollers 10, and the drive motor 8 is connected to one side of the rollers 10 for transmission. When the drive motor 8 starts, it drives the rollers 10 to rotate, thereby causing the conveyor belt 2 sleeved on the rollers 10 to circulate and realize the function of conveying the added material.

[0034] A filter plate 15 is detachably installed inside the collection tray 12, with one side of the filter plate 15 extending through the conveyor frame 1. A filter screen 18 is installed inside the filter plate 15. A slot 17 is provided on the inner wall of the collection tray 12, and the filter plate 15 is inserted into the slot 17. A handle 11 is provided at one end of the filter plate 15, with one side of the handle 11 located on the outside of the conveyor frame 1. This design allows the filter screen 18 to filter out impurities in the water during the water recycling process, preventing impurities from entering the water tank 5 and affecting the normal operation of the water pump. At the same time, the filter plate 15 can be easily pulled out of the slot 17 through the handle 11 for cleaning or replacement, ensuring the filtration effect.

[0035] A water inlet 6 is located on one side of the top of the water tank 5, and a dust cover can be detachably installed on the water inlet 6. When the water level in the water tank 5 is low, the dust cover of the water inlet 6 can be opened to add water, ensuring the normal operation of the entire cooling circulation system. The dust cover prevents dust and other impurities from entering the water tank 5 and contaminating the water source.

[0036] Several sets of support legs 7 are fixedly installed at the bottom of the conveyor frame 1, and each set of support legs 7 is equidistantly distributed at the bottom of the conveyor frame 1. The configuration of the support legs 7 provides stable support for the entire conveying device, ensuring that the device will not shake or tilt during operation, thus guaranteeing the safety and stability of the conveying operation.

[0037] In actual use, first, place the entire conveying device in a suitable position using the support legs 7, ensuring the device is stable. Then, inject an appropriate amount of water into the water tank 5 through the water inlet 6 and install the dust cover. Next, start the drive motor 8, which drives the drum 10 to rotate, causing the conveyor belt 2 to begin circulating. At this time, blast furnace smelting additives can be placed on the conveyor belt 2, and as the conveyor belt 2 rotates, the additives are transported to the designated location.

[0038] During the conveying process, due to the high temperature in the factory area, in order to prevent the conveyor belt 2 from being damaged by high temperature, and also to reduce the temperature of the additives, the water pump in the water tank 5 is started. The water pump delivers the water in the water tank 5 to the branch pipe 13 through the water supply pipe 3, and then sprays it out from the cooling nozzle 14 at the top of the branch pipe 13 to cool down the conveyor belt 2 and the additives.

[0039] After cooling, the water falls into the collection tray 12, and after impurities are filtered out by the filter screen 18 in the filter plate 15, it flows into the recovery pipe 4 through the outlet 16 and finally flows back into the water tank 5, realizing the recycling of water resources and achieving the purpose of energy saving.

[0040] When the filter plate 15 needs to be cleaned or replaced, simply hold the handle 11 and pull the filter plate 15 out of the slot 17. The operation is simple and convenient.

[0041] This utility model presents an efficient and energy-saving blast furnace smelting additive conveying device. By installing cooling nozzles 14 to cool the conveyor belt 2 and the additives, the service life of the conveyor belt 2 is extended. Simultaneously, the cooled water is recycled back to the water tank 5 via the recovery pipe 4, saving water resources and achieving energy conservation. Furthermore, the detachable design of the filter plate 15 facilitates the cleaning and replacement of the filter screen 18, ensuring the normal operation of the entire device. The coordinated operation of all components improves the efficiency and safety of blast furnace smelting additive conveying.

[0042] As a preferred example of this application, the inner wall of the conveyor frame 1 is made of a high-temperature resistant material. This design effectively prevents high-temperature additives from damaging the conveyor frame 1 and extends its service life.

[0043] As a preferred example of this application, the surface of the conveyor belt 2 is provided with anti-slip texture. The anti-slip texture design can increase the friction between the additive and the conveyor belt 2, prevent the additive from slipping during the conveying process, and ensure the stability of the conveying operation.

[0044] As a preferred example of this application, the bottom of the support leg 7 is provided with a shock-absorbing rubber pad. The shock-absorbing rubber pad can reduce the vibration and noise generated during the operation of the device, thereby improving the comfort of the working environment.

[0045] As a preferred example of this application, the cooling nozzle 14 is an atomizing nozzle. The atomizing nozzle can spray water in a mist form, increasing the contact area between the water and the additive, and improving the cooling effect.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
