Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal processing technology, and in particular to an intelligent coal washing and screening device. Background Technology
[0002] Coal processing is a series of physical and chemical treatments of mined raw coal. Its core is to remove impurities such as ash and sulfur through physical methods such as crushing, screening and washing, or to transform raw coal into products with better quality and wider applications through chemical conversion processes such as coking, gasification and liquefaction.
[0003] In the coal processing industry, washing and beneficiation are key steps to improve coal quality and remove impurities. However, existing coal washing technologies and equipment mostly employ a single-stage separation process. For some coals containing complex impurities or with uneven particle size distribution, a single-stage washing process is insufficient to completely remove harmful substances such as ash and sulfur, resulting in substandard coal product quality and affecting subsequent combustion efficiency and environmental performance.
[0004] Therefore, this utility model provides an intelligent coal washing and beneficiation device. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an intelligent coal washing and beneficiation device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent coal washing and screening device, including a base plate and a support frame, and a sorting component, wherein the sorting component includes a stirring component rotatably connected to the support frame, the stirring component having threaded blades fixedly connected inside, and a coal discharge pipe fixedly connected to the top outer side of the stirring component.
[0007] An impurity discharge assembly includes a hopper fixedly connected to the bottom of the agitator.
[0008] In a preferred embodiment, the outer side of the stirring element is provided with a through hole.
[0009] In a preferred embodiment, the mixing element is internally fixedly connected to a coal crushing channel.
[0010] In a preferred embodiment, the outer side of the threaded blade is in contact with the coal crushing flow channel.
[0011] In a preferred embodiment, a waste discharge pipe is fixedly connected to the bottom end of the hopper.
[0012] In a preferred embodiment, a pulverized coal flow pipe is fixedly connected to the bottom outer side of the agitator.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] This invention uses a stirring assembly to drive the spiral blades to rotate. During the rotation, the spiral blades crush and stir the coal, while simultaneously pushing the coal upwards. Higher density impurities in the coal sink and enter the hopper through the through-holes. The crushed coal is discharged through the crushed coal flow channel, the crushed coal circulation pipe, and the coal discharge pipe, while the impurities are discharged through the waste discharge pipe. This design achieves simultaneous coal crushing and impurity separation, improving the continuity and efficiency of coal processing. Through the spiral propulsion of the spiral blades and the screening effect of the through-holes, the separation of coal and impurities is more thorough, and the crushed coal has a more uniform particle size, which is convenient for subsequent processing.

[0023] 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.
[0024] like Figure 1 - Figure 3As shown, this embodiment provides a technical solution: an intelligent coal washing and screening device, including a base plate 1 and a support frame 2, and a sorting component 3. The sorting component 3 includes a stirring element 31 rotatably connected to the support frame 2. A threaded blade 32 is fixedly connected inside the stirring element 31. A coal discharge pipe 35 is fixedly connected to the top outer side of the stirring element 31. A through hole 33 is opened on the outer side of the stirring element 31. A crushed coal flow channel 34 is fixedly connected inside the stirring element 31. The outer side of the threaded blade 32 contacts the crushed coal flow channel 34. A crushed coal flow pipe 36 is fixedly connected to the bottom outer side of the stirring element 31.
[0025] The base plate 1 serves as the fundamental support structure of the entire device, bearing all key components such as the support frame 2, the sorting component 3, and the impurity discharge component 4, thus ensuring the stability and robustness of the entire device. The main function of the support frame 2 is to fix and support the agitator 31 in the sorting component 3, ensuring that the agitator 31 can rotate effectively in the appropriate position. Through its rotation, the agitator 31 agitates and crushes the coal, thereby separating the coal from impurities and providing the necessary power for coal transportation. The coal processed by the agitator 31 is discharged through the coal discharge pipe 35 for subsequent collection and processing. When the agitator 31 rotates, the spiral blades 32 further crush and agitate the coal using their spiral structure, while simultaneously pushing the coal upwards along the agitator 31. The device ensures that coal can smoothly enter the crushed coal flow channel 34. The through hole 33 serves as a channel for coal to flow inside the mixing element 31, allowing coal to smoothly enter the crushed coal flow channel 34, thus ensuring smooth coal flow and processing. The crushed coal flow channel 34 serves as a conveying channel for crushed coal, guiding the crushed coal to the crushed coal flow pipe 36, and finally discharging it through the coal discharge pipe 35. The crushed coal flow pipe 36 connects the crushed coal flow channel 34 and the coal discharge pipe 35, guiding the crushed coal from the crushed coal flow channel 34 to the coal discharge pipe 35, ensuring that the coal can be smoothly discharged from the device for subsequent collection and processing. Through these carefully designed components and channels, the entire device can efficiently complete the mixing, crushing, separation and discharge of coal, ensuring a smooth and efficient coal processing process.
[0026] like Figure 2 and Figure 4 As shown, the impurity discharge assembly 4 includes a hopper 41 fixedly connected to the bottom end of the agitator 31, and a waste discharge pipe 42 fixedly connected to the bottom end of the hopper 41.
[0027] The main function of the impurity discharge assembly 4 is to collect and discharge impurities separated from the coal. The hopper 41 is responsible for collecting the impurities separated from the bottom of the agitator 31, ensuring that the impurities can be effectively collected. This design not only facilitates the impurity collection process but also effectively prevents impurities from accumulating inside the device, thereby avoiding the negative impact of impurity accumulation on the washing and beneficiation effect. In addition, the waste discharge pipe 42 is responsible for discharging the collected impurities from the device, ensuring that the impurities can be smoothly removed from the system.
[0028] Working principle:
[0029] like Figure 1 - Figure 4 As shown:
[0030] In operation: First, coal enters the mixing element 31 through the feed inlet, located at the front of the device for easy coal input. The mixing element 31 is driven to rotate by an external power device, such as an electric motor or other type of drive equipment, ensuring continuous and stable rotation. As the mixing element 31 rotates, the spiral blades 32 also begin to rotate. The spiral blades 32 have a helical structure, which effectively crushes and mixes the coal during rotation. The purpose of crushing and mixing is to make the coal finer for easier subsequent processing and use. Inside the mixing element 31, the coal moves upward along the mixing element 31 under the push of the spiral blades 32. This process not only achieves coal crushing and mixing but also causes impurities in the coal to gradually sink due to density differences and other factors through gravity and centrifugal force. These sinking impurities enter the hopper 41 through the through hole 33 at the bottom of the mixing element 31. The hopper 41 is a device for collecting impurities, located below the mixing element 31, specifically for collecting and storing the impurities from the through hole 33. The coal is initially separated from the impurities by this method. As the agitator 31 continues to rotate, the crushed coal, driven by the threaded blades 32, enters the crushed coal flow channel 34 through the through hole 33. The crushed coal flow channel 34 is a specially designed channel to guide the crushed coal to the crushed coal flow pipe 36. The crushed coal flow pipe 36 is a connecting channel that transfers the crushed coal from the agitator 31 to the coal discharge pipe 35. The coal discharge pipe 35 is the outlet of the device, used to discharge the crushed coal from the device, thus realizing the smooth transportation and discharge of the crushed coal. At the same time, the hopper 41 collects the impurities separated from the bottom of the agitator 31. The hopper 41 not only collects impurities but also has a storage function, allowing the impurities to accumulate in it. When the impurities accumulate to a certain extent, they are discharged from the device through the waste discharge pipe 42. The waste discharge pipe 42 is a pipe specifically designed to discharge impurities, ensuring that the impurities can be smoothly discharged from the device. In this way, the collection and discharge process of impurities is completed, ensuring the clean and efficient operation of the device.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
