Description

Technical Field

[0001] The present application relates to the technical field of dust conveying, and in particular to a blue carbon dust conveying device. Background Art

[0002] In the existing technology, lignite can replace coke (metallurgical coke) and is widely used in chemical, smelting, gasification and other industries. It is superior to coke in the production of high-energy-consuming products such as metallic silicon, ferroalloys, ferrosilicon, silicon manganese, fertilizers, calcium carbide and so on. In order to make the lignite burn fully, it needs to be crushed into powder (i.e., lignite powder). During the crushing process, lignite will produce a large amount of lignite dust, which will flow with the air, not only causing the loss of lignite, but also polluting the air. Therefore, bag-type dust collectors are usually used to filter and recover the lignite dust. However, bag-type dust collectors are usually fixedly arranged, which makes it impossible to conveniently transport the filtered and recovered lignite dust. Utility Model Content

[0003] The problem to be solved by the present application is that although the existing bag-type dust collector can filter out and recover the lignite dust in the air, it does not have the problem of convenient transportation of the lignite dust.

[0004] In order to solve the above-mentioned technical problems, the present application provides a lignite dust conveying device, including a frame for supporting, a cyclone separator for air filtration operation is arranged on the upper part of the frame, a dust bucket connected to the cyclone separator for collecting lignite dust is arranged directly below the cyclone separator, and casters for easy walking are arranged at the lower part of the frame.

[0005] Since the conveying device of the present application is designed with a cyclone separator, a dust bucket and casters, it is possible to filter and recover the lignite dust in the air through the cyclone separator and the dust bucket, and to conveniently convey the lignite dust through the casters, thereby solving the problem that the bag-type dust collector used in the prior art can filter and recover the lignite dust in the air, but does not have the function of conveniently conveying the lignite dust.

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0013] The present application relates to a blue carbon dust conveying device, such as Figure 1-5 As shown, the conveying device includes a frame 3 for supporting, a cyclone separator 2 for air filtering operation is arranged on the upper part of the frame 3, and a dust bin 6 for collecting lignite dust is arranged directly below the cyclone separator 2 and is connected thereto. In order to facilitate the transportation operation of the dust bin 6, casters 5 for easy walking are arranged at the lower part of the frame 3, and in order to facilitate the user to push the conveying device for walking operation, a handrail 1 is also arranged on one side of the frame 3, and in order to perform disassembly and assembly operations of the cyclone separator 2 or the dust bin 6, a tool basket 4 for storing auxiliary tools is also arranged on the upper part of the frame 3.

[0014] The cyclone separator 2 includes a cyclone body 9, a cyclone inlet 8, and a cyclone outlet 7. The cyclone body 9 is arranged in a vertical direction, the cyclone inlet 8 is arranged in a vortex shape on one side of the top of the cyclone body 9, and the cyclone outlet 7 is arranged at the top center of the cyclone body 9. The cyclone body 9 is divided into a constant diameter section 10 and a variable diameter section 11. The constant diameter section 10 is arranged in the upper half of the cyclone body 9, and the variable diameter section 11 is arranged in the lower half of the cyclone body 9, so that the lignite dust entering the cyclone separator 2 can move downward in a spiral shape along the inner wall of the cyclone body 9, so that the lignite dust can accelerate its rotation after reaching the variable diameter section 11, thereby realizing the separation of air and lignite dust, so that the lignite dust is accumulated at the bottom of the cyclone body 9, and the separated air rises along the middle position of the bottom of the cyclone body 9 to the cyclone outlet 7, thereby realizing the collection operation of the lignite dust.

[0015] Since the dust bin 6 is arranged at the bottom of the cyclone separator 2 and is connected thereto, the lignite dust separated by the cyclone cylinder 9 will all be deposited inside the dust bin 6 under the action of its own gravity. In order to facilitate the observation of the amount of lignite dust accumulated inside the dust bin 6, the dust bin 6 can be made of transparent PVC material.

[0016] When in use, the cyclone outlet 7 of the cyclone separator 2 is connected to a negative pressure fan, which is used to extract the air containing the lignite dust in the lignite pulverizing equipment, so that the air containing the lignite dust enters the cyclone cylinder 9 along the cyclone inlet 8, so that the air moves downward along the inner wall of the cyclone cylinder 9 in a swirling manner, thereby moving from the constant diameter section 10 to the variable diameter section 11, so that most of the lignite dust is retained in the dust bin 6 at the bottom of the cyclone cylinder 9, while the air moves upward along the middle position of the cyclone cylinder 9, and then leaves through the cyclone outlet 7. After the dust bin 6 is full, take out the auxiliary tool from the tool basket 4, separate the cyclone separator 2 from the pulverizing equipment and the negative pressure fan, and then you can hold the handrail 1, and then use the casters 5 to push the cyclone separator 2 and the dust bin 6 on the upper part of the frame 3 to the lignite dust storage position, thereby realizing the convenient transportation operation after the lignite dust is collected.

[0017] It is to be understood that the present application is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application.
