Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal washing technology, specifically a flow guiding device for solving coal overflow in a hydrocyclone. Background Technology
[0002] The core objective of coal washing and processing is to utilize the differences in physical and chemical properties between coal and impurities to remove impurities such as gangue and pyrite from raw coal through mechanical methods, thereby improving coal quality. This process not only reduces ash and sulfur content but also reduces inefficient transportation and pollutant emissions, while simultaneously achieving the resource utilization of coal gangue.
[0003] In the coal washing and processing process, the density is usually properly proportioned for washing and separation into three products: fine, medium, and gangue. During production, problems such as coal particle size, impurities, or blockage of downstream equipment may cause material overflow or spillage. Once the overflow port is blocked, a large amount of water and medium will be lost, resulting in waste of the medium. In addition, a large area of water and coal accumulation will be generated, requiring sanitation treatment and increasing unnecessary workload. Therefore, this application proposes a flow guiding device to solve the above problems by addressing coal overflow in the hydrocyclone. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the shortcomings of the prior art, this utility model provides a flow guiding device to solve the problem of coal overflow in a hydrocyclone, thus solving the technical problems mentioned in the background.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a flow guiding device for solving coal overflow in a hydrocyclone, comprising a collection box, the collection box being installed at the top of a distribution box, and an assembly port being provided at the lower end of the collection box, and the overflow box opening at the top of the distribution box extending through the assembly port into the collection box, a flow guiding box being connected to one side of the collection box, and the other end of the flow guiding box being positioned directly above the arc screen, and the flow guiding box being inclined, with the end of the flow guiding box corresponding to the arc screen being the lower side.
[0008] Preferably, the bottom sidewall of the collector box is inclined, and the side of the bottom sidewall of the collector box that connects to the guide box is the lower side.
[0009] Preferably, the height of the three edge plates of the collector box is higher than 20cm, and the height of the two side edge plates of the guide box is higher than 10cm.
[0010] Preferably, the flow guide box is constricted at one end corresponding to the arc-shaped screen.
[0011] Preferably, the length of the flow guide box is adjusted according to the distance between the flow collector box and the downstream equipment.
[0012] Preferably, the overflow box opening is provided with three overflow slots, and the three overflow slots are distributed on both sides of the overflow box opening and on the side facing the overflow box.
[0013] (III) Beneficial Effects
[0014] The beneficial effects of this utility model are as follows:
[0015] This flow guiding device for solving coal overflow in hydrocyclones uses a collection box and a flow guiding box to guide the overflow liquid and coal slurry from the overflow box to the downstream arc screen. The overflow material can directly enter the downstream equipment along the flow guiding channel, effectively avoiding the occurrence of large amounts of water and media leakage. At the same time, the arc screen is used to screen the water and media in the overflow material for secondary recycling, avoiding the waste of water or other media. Attached Figure Description

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] like Figure 1-3As shown, this utility model provides a technical solution: a flow guiding device for solving coal overflow in a hydrocyclone, including a collection box 1. The bottom sidewall of the collection box 1 is inclined, and the side of the bottom sidewall of the collection box 1 connected to the flow guiding box 4 is the lower side. This arrangement ensures that the overflowing liquid and coal slurry flow to the flow guiding box 4. The collection box 1 is installed at the top of the distribution box 2, and an assembly port is opened at the bottom of the collection box 1. The overflow box port 3 at the top of the distribution box 2 extends into the collection box 1 through the assembly port. The flow guiding box 4 is connected to one side of the collection box 1. The liquid and coal slurry in the distribution box 21 overflow through the overflow channel of the overflow box port 3. The overflowing liquid and coal slurry enter the collection box 1 and flow into the flow guiding box 4. The overflowing material can directly enter the downstream equipment through the flow guiding box 4. The end of the flow guiding box 4 corresponding to the arc screen 5 is constricted. This arrangement ensures that the overflowing liquid and coal slurry flow to the downstream equipment. The relatively wide front section of the guide box 4 ensures smooth material transport, while the constricted rear section concentrates the material for downstream equipment. The length of the guide box 4 is adjusted according to the distance between the collecting box 1 and the downstream equipment. The other end of the guide box 4 is positioned directly above the arc screen 5, and the guide box 4 is tilted to ensure automatic material flow. The end of the guide box 4 corresponding to the arc screen 5 is lower. The height of the three edge plates of the collecting box 1 is higher than 20cm, and the height of the two side edge plates of the guide box 4 is higher than 10cm. The overflow box 3 has three overflow slots, which are distributed on both sides of the overflow box 3 and on the side facing the collecting box 4. This arrangement prevents the overflow liquid and coal slurry from flowing out from the side of the overflow box 3 away from the guide box 4, thus avoiding obstruction of the overflow liquid and coal slurry by the overflow box 3.
[0022] The operational steps for this application are as follows:
[0023] The liquid and coal slurry in the diversion box 2 will overflow through the overflow trough of the overflow box 3. After overflowing, the liquid and coal slurry will enter the collection box 1 and flow into the guide box 4. The overflow material can directly enter the downstream equipment through the guide box 4. The arc screen 5 can screen and separate the water or other media in the overflow material for secondary recycling.
