Abstract
Description
Technical Field
[0001] This application relates to the field of dust collection technology, and in particular to a dust collection device for molten iron tapping. Background Technology
[0002] In the metallurgical industry, a large amount of high-temperature dust is generated during the tapping of molten iron. This dust not only pollutes the environment but also poses a serious threat to the health of operators. Currently, metallurgical enterprises generally use technologies such as wet dust removal and baghouse dust collection for dust treatment. However, these methods have problems such as low efficiency and easy equipment damage when dealing with high-temperature and high-humidity dust. In recent years, with increasingly stringent environmental protection requirements, the development of efficient and durable dust collection devices has become an urgent need for the industry.
[0003] Among the existing technologies, commonly used dust collection methods all have some drawbacks. Wet dust collection systems consume a lot of energy during the dust collection process and are prone to causing secondary pollution. Electrostatic dust collection methods require more expensive equipment compared to other dust collection methods, and their cost-effectiveness is questionable. Baghouse dust collection methods are prone to damage under high temperature conditions and have a short service life.
[0004] Therefore, this application proposes a dust collection device for molten iron tapping. Utility Model Content
[0005] This application proposes a molten iron tapping dust collection device to solve the problems mentioned in the background art. This molten iron tapping dust collection device, by setting up a cooling mechanism, water tank, water pump, water supply pipe, diversion pipe, atomizing water nozzle, water inlet, and No. 1 cover, uses atomized water sprayed at high speed to cool down the high-temperature dust. It can efficiently handle high-temperature dust at low cost, reduce environmental pollution, and the cooled dust does not damage subsequent equipment, greatly improving the practicality of the device.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] A dust collection device for molten iron tapping includes an operation box. The operation box contains a molten iron collection structure, and its top is equipped with a dust collection structure. The dust collection structure contains a primary filtration structure. A cyclone separator is connected to one side of the dust collection structure. A cooling mechanism is located at the top of the cyclone separator. The cooling mechanism includes a water tank, which is fixedly connected to the top of the cyclone separator. A water pump is installed inside the water tank, and a water supply pipe is fixedly connected to the outlet of the water pump, extending into the dust collection structure. A distribution pipe is connected to the bottom of the water supply pipe, and multiple evenly installed atomizing water nozzles are fixedly connected to the surface of the distribution pipe, extending into the interior of the distribution pipe. A water inlet is connected to the top of the water tank, and a No. 1 cap is threaded onto the outside of the water inlet. A separation mechanism is located inside the cyclone separator, and a dust collection structure is located at the bottom of the cyclone separator. An inspection structure is located on the surface of the cyclone separator.
[0008] In a preferred embodiment, the molten iron collection structure includes a molten iron collection box, which is installed at the bottom of the inside of the operating box. A molten iron conveying trough is fixedly connected to one side of the operating box and extends into the inside of the operating box.
[0009] After the molten iron is generated, it is transported through the molten iron conveying trough and flows into the molten iron collection box for centralized collection. The molten iron collection box is located inside the operating box and is isolated from the outside, which ensures the safety of the personnel and improves the practicality of the device.
[0010] In a preferred embodiment, the dust collection structure includes a dust collection cover, which is fixedly connected to the top of the control box. A dust conveying cylinder is fixedly connected to the top of the dust collection cover, and the dust conveying cylinder is in communication with the control box.
[0011] When molten iron enters the molten iron collection box, it generates a large amount of high-temperature dust. The high-temperature dust is collected by the dust collection cover and then transported by the dust conveyor to the next step of the operation, which greatly increases the work efficiency and thus improves the practicality of the device.
[0012] In one preferred embodiment, the primary filtration structure includes a filter plate, which is slidably connected to the dust collection cylinder. A baffle is fixedly connected to one side of the filter plate, and a pull ring is fixedly connected to one side of the baffle.
[0013] After the dust enters the dust collection cylinder, some larger dust particles are filtered and adsorbed by the filter plate, which reduces the separation load of the subsequent cyclone separator. Pulling the pull ring can pull out the baffle, and the filter plate moves with the baffle, making it easy to replace the filter plate and thus improving the practicality of the device.
[0014] In a preferred embodiment, the separation mechanism includes a trapezoidal cylinder, which is fixedly connected to the inner wall of the cyclone separator. The bottom of the trapezoidal cylinder is connected to a secondary separation cylinder, and the bottom of the secondary separation cylinder is connected to an exhaust pipe, which extends to the outside of the cyclone separator. The bottom of the exhaust pipe is fixedly connected to a dust discharge pipe, which extends to the inside of the exhaust pipe.
[0015] After cooling, the dust enters the cyclone separator through the dust conveyor. During rotation, the dust particles are thrown against the inner wall of the cyclone separator and eventually fall down due to their own gravity. The gas and some of the separated particles enter the trapezoidal cylinder. After flowing into the secondary separation cylinder, the flow path decreases sharply and the flow velocity increases, which further increases the centrifugal force inside the secondary separation cylinder, causing the remaining dust particles to separate from the gas. Finally, the gas flows out through the exhaust pipe, and the remaining dust falls to the bottom of the cyclone separator through the dust discharge pipe, completing the separation and thus improving the practicality of the device.
[0016] In a preferred embodiment, the dust collection structure includes a dust collection pipe, which is fixedly connected to the bottom of the cyclone separator. The dust collection pipe extends into the interior of the cyclone separator, and the holes in the dust collection pipe correspond to the dust discharge pipe. A No. 2 cap is externally threaded to the bottom end of the dust collection pipe.
[0017] By opening the second cover, the separated dust particles fall to the bottom of the cyclone separator and can then be collected outside through the dust collection pipe, thus improving the practicality of the device.
[0018] In a preferred embodiment, the inspection structure includes an inspection door, which is hinged to the surface of the cyclone separator, and a handle is fixedly connected to the surface of the inspection door.
[0019] By pulling the handle, the inspection door can be opened, making it easy to observe the extent of damage to the internal components of the cyclone separator, facilitating timely maintenance, maintaining good working efficiency of the device, and thus improving the practicality of the device.
[0020] In a preferred embodiment, the dust collection cover is made of high-temperature resistant stainless steel, and the outer surface of the operating box has a heat insulation film made of polyurethane.
[0021] High-temperature resistant stainless steel can withstand continuous high temperatures, increasing the service life of the equipment. A layer of polyurethane heat insulation film is installed on the outside of the control box to protect the staff and prevent their safety from being affected, thereby improving the practicality of the equipment.
[0022] The beneficial effects of this application are:
[0023] 1. This iron tapping dust collection device, by setting up a cooling mechanism, water tank, water pump, water supply pipe, diversion pipe, atomizing water nozzle, water inlet, and No. 1 cover, facilitates the collection of high-temperature dust. The water pump is turned on, and water from the water tank is transported through the water supply pipe to the dust collection cylinder. The water is then diverted to both ends of the water supply pipe and finally sprayed out through multiple diversion pipes to cool the high-temperature dust flowing through the dust collection cylinder. When the water tank is low on water, the No. 1 cover can be opened, and water can be added through the water inlet to maintain a sufficient water supply. This mechanism utilizes the high-speed spraying of atomized water to cool the high-temperature dust, efficiently treating high-temperature dust at low cost, reducing environmental pollution, and ensuring that the cooled dust does not damage subsequent equipment, greatly improving the practicality of the device.
[0024] 2. This iron tapping dust collection device, by setting a primary filtration structure, filter plate, baffle, and pull ring, can reduce the separation load of the cyclone separator. After the dust enters the dust conveying cylinder, some larger dust particles are filtered and adsorbed by the filter plate, so as to reduce the separation load of the subsequent cyclone separator. Pulling the pull ring can pull out the baffle, and the filter plate moves with the baffle, which facilitates the replacement of the filter plate and greatly improves the practicality of the device.

Detailed Implementation
[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0032] Reference Figure 1-3 A dust collection device for molten iron tapping includes an operation box 1. The operation box 1 contains a molten iron collection structure 2, which includes a molten iron collection tank 21. The molten iron collection tank 21 is installed at the bottom of the operation box 1. A molten iron conveying trough 22 is fixedly connected to one side of the operation box 1, and the molten iron conveying trough 22 extends into the interior of the operation box 1. After molten iron is generated, it is conveyed through the molten iron conveying trough 22 and flows into the molten iron collection tank 21 for centralized collection. The molten iron collection tank 21 is located inside the operation box 1, isolated from the outside, ensuring the safety of personnel and thus improving the practicality of the device.
[0033] Reference Figure 1-4 The top of the control box 1 is equipped with a dust collection structure 3, which includes a dust collection cover 31 and is fixedly connected to the top of the control box 1. A dust conveying cylinder 32 is fixedly connected to the top of the dust collection cover 31 and is connected to the control box 1. When molten iron enters the molten iron collection box 21, a large amount of high-temperature dust will be generated. The high-temperature dust is collected by the dust collection cover 31 and transported by the dust conveying cylinder 32 for the next operation, which greatly increases the work efficiency and improves the practicality of the device.
[0034] Reference Figure 1-4 The dust collection structure 3 is equipped with a primary filtration structure 4, which includes a filter plate 41. The filter plate 41 is slidably connected to the dust collection cylinder 32. A baffle 42 is fixedly connected to one side of the filter plate 41, and a pull ring 43 is fixedly connected to one side of the baffle 42. After the dust enters the dust collection cylinder 32, some larger dust particles are filtered and adsorbed by the filter plate 41, so as to reduce the separation load of the subsequent cyclone separator 9. Pulling the pull ring 43 can pull out the baffle 42, and the filter plate 41 will move with the baffle 42, which makes it convenient to replace the filter plate 41, thereby improving the practicality of the device.
[0035] Reference Figure 1 , 23 and 5, a cyclone separator 9 is connected to one side of the dust collection cylinder 32. A cooling mechanism 5 is provided at the top of the cyclone separator 9. The cooling mechanism 5 includes a water tank 51, which is fixedly connected to the top of the cyclone separator 9. A water pump 52 is installed inside the water tank 51. A water supply pipe 53 is fixedly connected to the outlet of the water pump 52. The water supply pipe 53 extends into the interior of the dust collection structure 3. A diversion pipe 54 is connected to the bottom of the water supply pipe 53. Multiple evenly installed atomizing water nozzles 55 are fixedly connected to the surface of the diversion pipe 54. The atomizing water nozzles 55 extend into the interior of the diversion pipe 54. A water inlet 56 is connected to the top of the water tank 51. A No. 1 cover 57 is threadedly connected to the outside of the water inlet 56.
[0036] Reference Figure 1-2 The cyclone separator 9 is internally equipped with a separation mechanism 6, which includes a trapezoidal cylinder 61. The trapezoidal cylinder 61 is fixedly connected to the inner wall of the cyclone separator 9. The bottom of the trapezoidal cylinder 61 is connected to a secondary separation cylinder 62, and the bottom of the secondary separation cylinder 62 is connected to an exhaust pipe 63. The exhaust pipe 63 extends to the outside of the cyclone separator 9, and the bottom of the exhaust pipe 63 is fixedly connected to a dust discharge pipe 64, which extends into the interior of the exhaust pipe 63. The cooled dust enters the cyclone separator 9 through the dust conveying cylinder 32. Inside, during rotation, particulate dust is thrown against the inner wall of the cyclone separator 9 and eventually falls down due to its own gravity. Gas and some of the separated particles enter the trapezoidal cylinder 61 and flow into the secondary separation cylinder 62. The flow path decreases sharply and the flow velocity increases, which further increases the centrifugal force inside the secondary separation cylinder 62, causing the remaining dust particles to separate from the gas. Finally, the gas flows out through the exhaust pipe 63, and the remaining dust falls to the bottom of the cyclone separator 9 through the dust discharge pipe 64, completing the separation and thus improving the practicality of the device.
[0037] Reference Figure 1-3 The bottom of the cyclone separator 9 is provided with a dust collection structure 7, which includes a dust collection pipe 71. The dust collection pipe 71 is fixedly connected to the bottom of the cyclone separator 9 and extends into the interior of the cyclone separator 9. The holes of the dust collection pipe 71 correspond to the dust discharge pipe 64. The bottom end of the dust collection pipe 71 is externally threaded with a second cover 72. By opening the second cover 72, the separated dust particles fall to the bottom of the cyclone separator 9 and can then fall to the outside through the dust collection pipe 71 for easy collection, thereby improving the practicality of the device.
[0038] Reference Figure 1-3The surface of the cyclone separator 9 is provided with an inspection structure 8, which includes an inspection door 81. The inspection door 81 is hinged to the surface of the cyclone separator 9, and a handle 82 is fixedly connected to the surface of the inspection door 81. By pulling the handle 82, the inspection door 81 can be opened, making it convenient to observe the degree of damage to the internal components of the cyclone separator 9, facilitating timely maintenance, maintaining good working efficiency of the device, and thus improving the practicality of the device.
[0039] Reference Figure 1-3 The dust collection cover 31 is made of high-temperature resistant stainless steel, and the outer surface of the control box 1 has a heat insulation film made of polyurethane. The high-temperature resistant stainless steel can withstand continuous high temperatures, which increases the service life of the device. The polyurethane heat insulation film on the outside of the control box 1 can protect the staff and prevent their safety from being affected, thereby improving the practicality of the device.
[0040] Working Principle: When the device is in use, molten iron is transported through the molten iron conveying trough 22 and flows into the molten iron collection tank 21 for centralized collection. Upon entering the molten iron collection tank 21, a large amount of high-temperature dust is generated. This high-temperature dust is collected by the dust collection cover 31 and then transported centrally through the dust conveying cylinder 32. After entering the dust conveying cylinder 32, larger dust particles are filtered and adsorbed by the filter plate 41 to reduce the separation load on the subsequent cyclone separator 9. The water pump 52 is turned on, and water from the water tank 51 is transported through the water pipe 53 to the dust conveying cylinder 32. The water is then split at both ends of the water pipe 53 and finally sprayed out as a mist through multiple diversion pipes 54 to cool the high-temperature dust flowing through the dust conveying cylinder 32. If the water tank 51 is short of water, one of the water pumps can be turned on. Water is added to the water tank 51 through the water inlet 56 via the cover 57 to ensure a sufficient water supply. After cooling, the dust enters the cyclone separator 9 through the dust conveyor 32. During rotation, the dust particles are thrown against the inner wall of the cyclone separator 9 and eventually fall down by their own gravity. The gas and some of the separated particles enter the trapezoidal cylinder 61 and flow into the secondary separation cylinder 62. The flow path decreases sharply and the flow velocity increases, which further increases the centrifugal force inside the secondary separation cylinder 62, causing the remaining dust particles to separate from the gas. Finally, the gas flows out through the exhaust pipe 63, and the remaining dust falls to the bottom of the cyclone separator 9 through the dust discharge pipe 64, completing the separation. After opening the second cover 72, the separated dust particles fall to the bottom of the cyclone separator 9 and can fall to the outside through the dust collection pipe 71 for easy collection.
[0041] Pulling handle 82 opens inspection door 81, allowing for easy observation of the extent of damage to internal components of cyclone separator 9, facilitating timely maintenance and maintaining good operating efficiency. High-temperature resistant stainless steel can withstand continuous high temperatures, increasing the service life of the device. A layer of polyurethane heat insulation film is installed on the outside of the control box 1 to protect the staff and prevent their safety from being compromised.
