Description

Technical Field

[0001] The utility model relates to the technical field of smoke hoods, in particular to a dust suction smoke hood for ferrosilicon alloy casting. Background Art

[0002] Ferrosilicon is an ferroalloy composed of silicon and iron. It is a commonly used deoxidizer and alloy additive in the steelmaking industry. Due to the strong chemical affinity between silicon and oxygen, ferrosilicon can be used as a strong deoxidizer in the steelmaking process for precipitation and diffusion deoxidation to improve the quality of steel. In addition, ferrosilicon can also be used as an alloying element additive and is widely used in the production of steel products such as low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is also commonly used as a reducing agent in ferroalloy production and the chemical industry. Since a large amount of smoke will be generated during the smelting and casting process of ferrosilicon, this smoke not only pollutes the environment, but also harms the health of workers. Therefore, dust hoods are needed to effectively collect and treat these smoke.

[0003] A smoke hood is provided directly above each casting area. However, in the actual production process, not all casting areas will carry out casting operations. Therefore, using a mobile dust hood for smoke removal can avoid unnecessary waste of resources. However, the existing mobile dust hood is installed with universal wheels for easy movement, resulting in insufficient stability when smoke removal operations are required. It is easy to shake, thereby affecting work efficiency.

[0004] In view of the above problems, the utility model provides a dust extraction hood for ferrosilicon alloy casting. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] See also Figure 1-Figure 5 In order to solve the problem that the existing mobile dust hood is equipped with universal wheels for easy movement, which leads to insufficient stability and easy shaking when the smoke and dust removal operation is required, thus affecting the work efficiency, the following preferred technical solutions are provided:

[0024] A dust collecting hood for ferrosilicon alloy casting comprises a mounting support 1 and a mounting frame 2 fixedly connected to the upper end of the mounting support 1, a hood body 3 is fixedly connected to one end of the mounting frame 2 away from the mounting support 1, the hood body 3 is welded by 6mm steel plate and 120-type channel steel, and a fire-resistant layer is laid on the surface, a smoke exhaust pipe 4 is connected to the upper end of the hood body 3, an opening control box 5 is installed on one side of the hood body 3 for adjusting a valve, and the dust collecting effect is adjusted by the opening of the valve, a universal wheel 6 and a supporting mechanism 7 are fixedly connected to the lower end of the mounting support 1, and the supporting mechanism 7 comprises a motor 71 installed in the internal channel of the fixed mounting support 1, a threaded rod 72 is fixedly connected to the output end of the motor 71, a movable block 73 is threadedly sleeved on the outer wall of the threaded rod 72, a middle connecting block 74 is fixedly connected to the lower end of the movable block 73, a support plate 75 is fixedly connected to the lower end of the middle connecting block 74, and a suction cup assembly 76 is fixedly connected to the lower end of the support plate 75.

[0025] The movable block 73 is slidably connected to the internal channel of the mounting support 1, and the diameter of the middle block 74 is larger than the inner diameter of the internal channel of the mounting support 1. When the middle block 74 fits the bottom plate of the mounting support 1, the universal wheel 6 is supported on the ground.

[0026] Specifically, when the universal wheel 6 is supported on the ground, the device can be moved through the universal wheel 6. At this time, the middle block 74 is in contact with the bottom plate of the mounting support 1. When the device needs to be stably used for smoking and dust removal operations, the motor 71 is started, and the motor 71 is used to drive the threaded rod 72 to rotate. When the threaded rod 72 rotates, the movable block 73 drives the support plate 75 to move downward through the middle block 74 until the suction cup assembly 76 supports the ground. The suction cup assembly 76 is used to ensure that the device will not shake, and the smoking and dust removal are stable. This solves the problem that the existing mobile dust hood is installed with universal wheels for the convenience of movement, which leads to insufficient stability and easy shaking when smoking and dust removal operations are required, thereby affecting work efficiency. When it is necessary to move again, it is only necessary to use the motor 71 to drive the threaded rod 72 to rotate in the opposite direction, drive the suction cup assembly 76 to move up, and make the universal wheel 6 support the ground again.

[0027] The suction cup assembly 76 includes an upper disk body 761, one end of which is fixedly connected to the support plate 75, and a lower disk body 762 arranged at the lower end of the upper disk body 761, the lower end of the upper disk body 761 is fixedly connected to a sealing block 763, the upper end of the lower disk body 762 is provided with a sealing opening 764, the sealing opening 764 is connected to the inner cavity of the lower disk body 762, and elastic elements 765 are fixedly connected to both sides of the sealing block 763, and one end of the elastic element 765 away from the sealing block 763 is fixedly connected to the inner wall of the sealing opening 764, the shape of the sealing block 763 is a truncated cone, the maximum diameter of the sealing block 763 is larger than the inner diameter of the sealing opening 764, and the minimum diameter of the sealing block 763 is smaller than the inner diameter of the sealing opening 764.

[0028] Specifically, when the suction cup assembly 76 supports the ground, the sealing block 763 is compressed to block the sealing port 764, and the lower disk body 762 is used to discharge the internal air and adsorb to the ground. When the device needs to move the suction cup assembly 76 upward, the upper disk body 761 will drive the sealing block 763 to gradually separate from the sealing port 764. Since the maximum diameter of the sealing block 763 is larger than the inner diameter of the sealing port 764, and the minimum diameter of the sealing block 763 is smaller than the inner diameter of the sealing port 764, the external gas will enter the lower disk body 762 at this time, releasing the adsorption of the lower disk body 762, and the conversion efficiency of the supporting component is high, and the operation is extremely convenient.
