Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to an intelligent coal preparation production device. Background Art

[0002] In the coal industry, coal preparation is a key link in improving coal quality and achieving efficient and clean utilization of coal. With the rapid development of modern industry and increasingly stringent environmental protection requirements, traditional coal preparation technology and equipment are facing many challenges, making the research and development of intelligent coal preparation production equipment an inevitable trend.

[0003] Traditional coal preparation processes rely heavily on manual operation and simple mechanical coordination, which has many drawbacks. In the coal transportation and feeding process, the lack of precise control means can easily lead to unstable coal flow, which not only affects the continuity of subsequent coal preparation processes, but may also cause equipment failure and production stagnation due to coal accumulation or insufficient supply. For example, in some old coal preparation plants, the feeder can only roughly adjust the feeding speed, which is difficult to adapt to the dynamic changes of different types of coal and production needs. Coal frequently blocks the transportation pipeline or silo, which seriously reduces production efficiency and increases equipment maintenance costs and manual cleaning workload.

[0004] As an important part of the coal preparation process, the crushing process is difficult for traditional crushers to achieve precise crushing particle size control when facing raw coal of different hardness and uneven particle size distribution. Operators often adjust the crusher parameters based on experience, which not only leads to uneven particle sizes of coal products after crushing, and cannot meet the market demand for coal of specific particle sizes, but also easily causes energy waste and excessive wear of equipment. For example, when crushing coal with higher hardness, if the speed and gap of the crusher hammer are set unreasonably, large pieces of coal may not be fully crushed, while small pieces of coal may be over-crushed, which reduces the utilization rate of coal resources, accelerates the wear of key components such as hammers and liners, and increases the frequency of equipment maintenance and replacement costs. This patent is to provide an intelligent coal preparation production device to alleviate the existing problems in the prior art in the coal transportation and feeding links, which lack some control means, easily lead to unstable coal flow, not only affect the continuity of subsequent coal preparation processes, but also may cause equipment failure and production stagnation due to coal accumulation or insufficient supply.

[0032] In this embodiment, the crushing mechanism can be used to crush the coal into a suitable size, which is convenient for the subsequent separation of the quality of the selected coal.

[0033] In one embodiment, for the third conveyor belt 30, a plurality of fixed bars 31 are arranged on the surface of the third conveyor belt 30, an opening for conveying coal is arranged at one end of the crusher housing 7, and an outlet for outputting coal is arranged at the bottom of the crusher housing 7.

[0035] In this embodiment, by setting stabilizing blocks 37 on both sides of the thick lead screw 34, the stability of the thick lead screw can be increased when it rotates.

[0036] In one embodiment, for the fitting block 19, the fitting block 19 is fixedly connected to the fixing frame 15, and a plurality of groups of crushing hammers 23 for crushing coal are arranged inside the crusher housing 7.

[0037] In this embodiment, by fixing the fitting block 19 on the inner wall of the fixing frame 15, the size of the baffle can be controlled when adjusting the baffle.

[0038] In one embodiment, for the second supporting frame 6 , one end of the second supporting frame 6 is provided with a transverse plate which can transport the coal to the inside of the crusher casing 7 .

[0039] In this embodiment, during the process of transporting coal, the coal can be directly transported to the inside of the crusher casing 7 through the first conveyor belt 4, which further increases the overall intelligence.

[0040] In one embodiment, for the anti-blocking box 2, holes for conveying coal into the interior are arranged on the top of the anti-blocking box 2, holes for conveying coal to the surface of the first conveyor belt 4 are arranged on the side of the anti-blocking box 2, and multiple groups of connecting rods 22 for fixing are arranged on the side of the baffle 24.

[0041] In this embodiment, the anti-blocking box 2 is provided to ensure that in the process of transporting coal, the problem of inaccurate weighing caused by the huge amount of coal transported can be prevented.

[0042] The working principle of the intelligent coal preparation production device in the present invention is that first, the coal is transported to the hole above the anti-blocking box 2, and the appropriate amount of coal is accurately input according to the actual production needs. At this time, the cam 13 starts to rotate, and its periodic motion law causes the sliding rod 12 to slide upward, and the compression spring 10 is compressed. Then, the sliding rod 12 transmits the shaking force to the shaking plate 8. Through this periodic shaking, the coal is effectively prevented from accumulating in the anti-blocking box 2 and causing blockage, ensuring the smooth passage of coal.

[0043] Subsequently, the coal of suitable size is smoothly transported to one end under the rotation drive of the first conveyor belt 4, and smoothly slides into the crusher housing 7. In this link, the staff accurately adjusts the position relationship of the first sliding column 16, the second sliding column 17 and the third sliding column 18 according to the specific specifications and texture requirements of the required coal products, and drives the slider 20 to move precisely on the screw rod by rotating the threaded screw rod 21, so as to finely control the gap size between the baffle 24 and the crushing hammer 23. When the crushing hammer 23 rotates at a high speed, the large pieces of coal are crushed into coal fragments that meet the predetermined standards under the action of its strong impact and crushing force, and these coal fragments then fall from the bottom of the crusher housing 7 to the surface of the second conveyor belt 25.

[0044] On the second conveyor belt 25, with the help of the transmission power of the second rotating roller 29, the second conveyor belt 25 runs stably, and at the same time, the first rotating roller 28 on the other side thereof cooperates with the transmission to transfer the coal accurately from the second conveyor belt 25 to the surface of the third conveyor belt 30. Afterwards, the coal falls into the sorting pool 27 along with the transmission of the third conveyor belt 30.

[0045] In the sorting tank 27, after sufficient sedimentation and floating process, the clean coal floats above the specific coal floating solution due to its low density, while impurities with high density such as gangue settle to the bottom of the sorting tank 27. At this time, the fixed bar 31 located on the third conveyor belt 30 plays a driving role, pushing the clean coal to the side of the sorting tank 27 with a specific hole for subsequent collection and processing. At the same time, the coarse screw 34 rotates, driving the threaded moving plate 35 to rotate, and then driving the sorting bar 36 to clean and collect the gangue at the bottom of the sorting tank 27. After the sedimentation process is completely completed, the third conveyor belt 30 is started, and the clean coal flows out from the upper opening of the sorting tank 27 and enters the next production process, while the gangue is discharged from the lower opening and transported to a special processing area, thereby realizing intelligent and efficient sorting and processing of coal materials.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
