Description

Technical Field

[0001] This utility model relates to the field of calcined magnesia production technology, specifically a dust collection device for calcined magnesia production. Background Technology

[0002] Magnesia, also known as sintered magnesia, is produced by calcining magnesium hydroxide, which is obtained by reacting magnesite, magnesia, or seawater with lime slurry. It has a strong hydration ability and is mainly used to make alkaline refractory materials, such as magnesia bricks and magnesia-alumina bricks. Magnesia with more impurities is used to pave the bottom of steelmaking furnaces. Magnesia production requires the use of a feeding device, but the existing feeding device generates a lot of dust when feeding raw materials. If operators inhale the dust, it will cause harm in the long term. The collected dust floats inside the dust storage box and will also float out when the collected dust is cleaned, thus polluting the environment. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0020] Please see Figure 1 As shown, this utility model provides a dust collection device for the production of calcined magnesia, including a processing furnace 1. A feed pipe 2 is connected to the right side of the top of the processing furnace 1. An annular dust suction pipe 3 is provided above the feed pipe 2. A dust suction pump 6 is connected to the top of the annular dust suction pipe 3 through a pipe. The ash discharge pipe of the dust suction pump 6 is connected to a dust storage box 5. A water storage box 8 is placed at the bottom of the front of the processing furnace 1. A water pump 9 is connected to the top of the water storage box 8. The water outlet pipe of the water pump 9 is connected to an atomizing spray pipe 10. The water spraying part of the atomizing spray pipe 10 is embedded in the interior of the dust storage box 5.

[0021] This technical solution utilizes a water storage tank 8 and an atomizing nozzle 10. The atomizing nozzle 10 is embedded on one side of the dust storage box 5 to atomize and humidify the dust entering the dust storage box 5, allowing the dust to fall into the dust collection hopper 11 under the influence of gravity, preventing the dust from floating inside. Moreover, the dust is concentrated inside the dust collection hopper 11, which is convenient for later centralized cleaning. It will not float when being poured out, thus improving the efficiency of dust collection and cleaning. Example 2:

[0022] Based on Embodiment 1, this utility model is as follows: Figure 1 As shown, a shielding frame 7 is fixedly installed on the left side of the top of the processing furnace 1, and the shielding frame 7 covers the outside of the dust collection box 5.

[0023] Adopting such Figure 1 The technical solution shown involves welding and reinforcing the shielding frame 7 to the processing furnace 1, which forms a shielding structure at the front end of the dust storage box 5, ensuring the stability of the dust storage box 5 after it is installed on the processing furnace 1.

[0024] Secondly, in the technical solution, a positioning support frame 4 is fixedly installed on the top of the processing furnace 1 and on the left side of the feed pipe 2. The dust pump 6 is located on the top of the front of the positioning support frame 4 and is connected by a support plate. A dust collection hopper 11 is pulled out and installed inside the dust collection box 5. A sealing baffle is fixedly installed on the back of the dust collection hopper 11 and the sealing baffle is attached to the back of the dust collection box 5.

[0025] Its adoption is as follows Figure 1 The technical solution shown features a pull-out design inside the dust collection hopper 11 in the dust storage box 5, which facilitates centralized cleaning of dust. Moreover, after the dust enters the dust storage box 5, the water sprayed out by atomization can humidify the dust and cause it to fall into the dust collection hopper 11, preventing the dust from floating inside. Example 3:

[0026] This utility model is as follows Figures 1-4As shown, a diagonal brace 12 is fixedly installed on the left side of the front of the processing furnace 1. The upper end of the diagonal brace 12 is connected to the bottom of the shielding frame 7. A discharge pipe 13 is connected to the left side of the processing furnace 1. A bearing plate 14 is fixedly installed on the bottom of the front of the processing furnace 1. The top of the bearing plate 14 is connected to the bottom of the water storage tank 8.

[0027] Using the above technical solution, the inclined brace 12 mainly supports and reinforces the bottom of the shielding frame 7, while the bearing plate 14 supports the bottom of the water storage tank 8, ensuring the stability of the water storage tank 8 after it is placed in front of the processing furnace 1.

[0028] The working principle of this utility model is as follows: When feeding, a large amount of dust is generated and the dust floats upward. The dust pump 6 is started to drive the annular dust suction pipe 3 to absorb the floating dust. The dust is then transported to the inside of the dust storage box 5. The water pump 9 transports the water in the water storage tank 8 to the atomizing spray pipe 10 and atomizes it to spray out, which can humidify the floating dust inside. After being humidified, the dust falls into the inside of the dust collection hopper 11 due to gravity, preventing the dust from floating inside. Moreover, the dust is concentrated inside the dust collection hopper 11, which is convenient for centralized cleaning later.
