Abstract
Description
Technical Field
[0001] This utility model relates to the field of coke production technology, and more specifically, to a fine powder screening device. Background Technology
[0002] During the coke loading process, there are strict requirements for the quality of coke, including the proportion of coke powder. Coke powder is a fine particle produced during the coke production process, and its content has an important impact on the overall quality of coke. In the traditional coke loading process, the hopper usually adopts a single-layer grate. This design has limited effect on the separation of coke powder and coke particles when the coke falls, often resulting in uneven mixing of coke powder and coke particles in the coke after loading, which affects the quality of coke.
[0003] Therefore, there is an urgent need for a fine powder sieving device to solve the above problems. Utility Model Content
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a fine sieving device. By incorporating a primary sieving screen, a secondary sieving screen, and a primary feeding channel, this utility model can improve the sieving effect of coke during its descent, enabling better separation of coke powder and coke particles, thereby improving the quality of coke after loading and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fine powder screening device, comprising a coke powder bin and a coke bin, wherein the coke powder bin is disposed on one side of the coke bin, a feeding conveyor belt is disposed on the top of the coke powder bin, a dust cover is disposed on the side of the feeding conveyor belt near the coke bin, a primary powder screening screen is disposed at the bottom of the dust cover, a primary discharge channel is disposed at the bottom of one side of the primary powder screening screen, a guide plate is welded to the bottom between the primary discharge channel and the primary powder screening screen, a secondary discharge channel is disposed at the bottom of the guide plate, a secondary powder screening screen is fixedly installed on one side of the top of the secondary discharge channel, and a return channel is disposed between the secondary powder screening screen and the coke powder bin.
[0006] In a preferred embodiment, the primary discharge channel is connected to the top of the coke bin.
[0007] In a preferred embodiment, the secondary discharge channel is connected to the top of the coke bin.
[0008] In a preferred embodiment, the return channel is connected to the coke powder silo.
[0009] The technical effects and advantages of this utility model are as follows:
[0010] This invention, by incorporating a primary sieve, a secondary sieve, and a primary feeding channel, improves the screening effect of coke during its descent, enabling better separation of coke powder and coke particles, thereby enhancing the quality of the coke after loading.

[0012] The attached diagram is labeled as follows: 1. Coke powder bin; 2. Coke bin; 3. Feeding conveyor belt; 4. Feeding conveyor belt; 5. Primary sieve; 6. Primary discharge channel; 7. Guide plate; 8. Secondary discharge channel; 9. Secondary sieve; 10. Return channel. Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] As attached Figure 1 As shown, this utility model provides a fine powder screening device, including a coke powder bin 1 and a coke bin 2. The coke powder bin 1 is located on one side of the coke bin 2. A feeding conveyor belt 3 is provided on the top of the coke powder bin 1. A dust cover 4 is provided on the side of the feeding conveyor belt 3 near the coke bin 2. A primary powder screening screen 5 is provided at the bottom of the dust cover 4. A primary discharge channel 6 is provided at the bottom of one side of the primary powder screening screen 5. A guide plate 7 is welded to the bottom between the primary discharge channel 6 and the primary powder screening screen 5. A secondary discharge channel 8 is provided at the bottom of the guide plate 7. A secondary powder screening screen 9 is fixedly installed on one side of the top of the secondary discharge channel 8. A return channel 10 is provided between the secondary powder screening screen 9 and the coke powder bin 1.
[0015] The primary discharge channel 6 is connected to the top of the coke bin 2.
[0016] The secondary discharge channel 8 is connected to the top of the coke bin 2.
[0017] The return channel 10 is connected to the coke powder silo 1.
[0018] The specific implementation method is as follows: When using this utility model, the feeding conveyor belt 3 starts and transports coke. Then the coke enters the dust cover 4 and falls onto the primary sieve screen 5. At this time, the coke powder and a small amount of coke particles in the coke will pass through the primary sieve screen 5 and fall onto the secondary sieve screen 9. After being screened by the secondary sieve screen 9, the coke powder will fall into the return channel 10 and enter the coke powder bin 1 for collection. The coke particles that have been screened will enter the coke bin 2 for collection through the primary discharge channel 6 and the secondary discharge channel 8. This utility model can improve the screening effect of coke during the falling process, so that the coke powder and coke particles can be better separated, thereby improving the quality of coke after loading.
[0019] Working principle of this utility model:
[0020] Refer to the instruction manual appendix Figure 1 When using this utility model, by providing a primary sieve screen 5, a secondary sieve screen 9, and a primary feeding channel 6, this utility model can improve the sieving effect of coke during the falling process, so that coke powder and coke particles can be better separated, thereby improving the quality of coke after loading.
