Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, and in particular to a peat refining and dewatering device. Background Technology

[0002] Peat, also known as sphagnum moss or peat, is a loose organic matter deposit composed of incompletely decomposed plant remains, humus, and minerals, formed by biological and chemical processes in a waterlogged and oxygen-deficient environment. Freshly mined peat has a high moisture content, resulting in poor performance and increased transportation costs. Typical equipment performs refining and dehydration processes to reduce the moisture content of peat.

[0003] Chinese invention application (title: Dehydration Furnace for Peat Drying, application number: 202210358350.X, publication number: CN114485130A, publication date: 20220513) discloses a dehydration furnace for peat drying, including a crushing and dehydrating box and a drying box. The crushing and dehydrating box is fixedly connected to the drying box by support frames set on both sides. After wet coal enters the crushing and dehydrating box through the wet coal inlet, small pieces and small particles of coal fall into the drying box through the coal leakage port below the crushing and dehydrating box under the tumbling component for drying. Large pieces of coal are first cut by the spiral slicing blade on the main shaft. At the same time, the electric heating wire inside the rotating rod preheats the coal pieces, so that the moisture on the outer layer of the large coal pieces is pre-evaporated. The air inside the drying box and the conveyor belt are heated by the electric heating tube in the middle of the conveyor belt, which can dry and evaporate the internal moisture of the small pieces and small particles of coal falling into the conveyor line of the drying box. However, the dewatering furnace for peat drying relies on spiral slicing plates on the main shaft to cut the peat. If the pitch of the spiral slicing plates is too large, the crushing effect is poor; if the pitch of the spiral slicing plates is too small, they are prone to jamming and are inconvenient to clean.

[0043] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0044] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0045] Figure 1 This is a front view of the peat refining and dewatering device in the embodiment. Figure 2 for Figure 1 Sectional view along line AA. Figure 3 This is a three-dimensional structural diagram of the peat refining and dewatering device in the embodiment. Figure 1 . Figure 4 This is a three-dimensional structural diagram of the peat refining and dewatering device in the embodiment. Figure 2 .like Figure 1 and Figure 2 As shown, the peat refining and dewatering device includes a support frame 100, a rotary cutting unit 200, and a hot rotary dewatering unit 300. The rotary cutting unit 200 and the hot rotary dewatering unit 300 are arranged in a straight line on top of the support frame 100, with the output end of the rotary cutting unit 200 extending into the rotating part of the hot rotary dewatering unit 300. The axial centers of the rotating parts of the rotary cutting unit 200 and the hot rotary dewatering unit 300 coincide, and their axial centers form a certain angle with the horizontal direction, such as a suitable angle of 0.5° to 3°, allowing the peat to gradually shift from a higher to a lower position under gravity. The peat is first shredded at high speed by the rotating part of the rotary cutting unit 200 to reduce its volume, and then tumbled and dehydrated by the rotating part of the hot rotary dewatering unit 300.

[0046] Compared with the prior art, this embodiment uses an external rotary cutting unit to chop the peat, and the degree of chopping can be adjusted according to needs (such as adjusting the rotation speed), and it is easy to clean up when the peat accumulates.

[0047] The following provides a detailed description of each component in this embodiment.

[0048] like Figures 2-4 As shown, the rotary cutting unit 200 includes a U-shaped first base 210, a first motor 220, and a cylindrical rotary cutting housing 230 closed at one end. The U-shaped first base 210 is mounted on the support frame 100. The rotary cutting housing 230 is arranged horizontally, with its axial center making an angle of 0.5° to 3° with the horizontal direction; the axial center of the first motor 220 coincides with the axial center of the rotary cutting housing 230, and the two are respectively located on both sides of the groove width direction of the U-shaped first base 210. A rotary cutting shaft 240 is located at the axial center of the rotary cutting housing 230, with one end of the rotary cutting shaft 240 passing through the closed end of the rotary cutting housing 230 and connected to the power output end of the first motor 220. One or more cutter assemblies 250 are detachably mounted on a corresponding portion of the rotary cutting shaft 240 located inside the rotary cutting housing 230. The cutter assembly 250 consists of a blade retaining ring 251 and blades 252 evenly arranged circumferentially along the outer side wall of the blade retaining ring 251. A feed inlet 231 is located at the top of the end of the rotary cutting housing 230 adjacent to the first motor 220. The end of the rotary cutting housing 230 extends into the hot rotary dewatering unit 300. Thus, the peat added through the feed inlet 231 is shredded at high speed by the combined action of the first motor 220, the rotary cutting shaft 240, and the cutter assembly 250, resulting in a reduced volume. In this embodiment, the degree of pulverization can be controlled by adjusting the rotation speed of the first motor and the installation position and number of the cutting blade assembly; and when pulverized coal accumulates in the rotary cutting unit 200 and affects rotary cutting, the machine can be stopped quickly for corresponding processing.

[0049] Furthermore, such as Figures 2-4 As shown, to facilitate observation of the peat chopping degree, a U-shaped guide section 232 is formed near the open end of the rotary cutting shell 230. The end of the U-shaped guide section 232 extends into the hot rotary dewatering unit 300, and the cutter assembly 250 is hidden within the remaining part of the rotary cutting shell 230 except for the U-shaped guide section 232. In this embodiment, the peat chopping degree can be directly observed through the U-shaped guide section 232, facilitating timely adjustment.

[0050] like Figures 1-4As shown, the hot cyclone dehydration unit 300 includes an open-end roller 310, an open heating cylinder 320, a second motor 330, and a second base 340. The heating cylinder 320 is horizontally mounted on the support frame 100, with its axial center coinciding with the axial center of the rotary cutting shell 230. Near the open ends of the heating cylinder 320, there is an annular support portion 321, and a bushing (not shown) is provided on the inner surface of the annular support portion 321. The roller 310 has the same axial length as the heating cylinder 320. The roller 310 is arranged coaxially with the heating cylinder 320 inside the heating cylinder 320, and the outer walls at both ends of the roller 310 contact the bushings on the annular support portions 321 on both sides. The end of the U-shaped guide portion 232 extends into the input start end of the adjacent roller 310. Several electric heating elements 350, such as heating rods, are arranged in the annular area surrounded by the drum 310, the heating cylinder 320, and the annular support portions 321 at both ends of the heating cylinder 320. The electric heating elements 350 are arranged on the inner wall of the heating cylinder 320 so as not to affect the rotation process of the drum 310. The second motor 330 and the second base 340 are located near the other end of the heating cylinder 320 away from the rotary cutting shell 230. The second base 340 is arranged on the support frame 100, and the second motor 330 is arranged on the second base 340. The power output end of the second motor 330 is provided with a hot rotating shaft 360. The other end of the hot rotating shaft 360 is connected to the output end of the adjacent drum 310 by a Y-type connecting frame 370, and the axial center of the hot rotating shaft 360 coincides with the axial center of the drum 310. Therefore, the operation of the second motor 330 can drive the drum 310 to rotate, further causing the shredded peat inside the drum 310 to tumble and gradually move towards the output end of the drum 310; the electric heating element 350 generates heat and gradually transfers it to the drum 310 and the tumbling peat, causing the moisture to evaporate and thus achieving peat dehydration, that is, reducing the moisture content of the peat to below a preset value, such as a moisture content of less than 10%; the dehydrated peat is removed from the output end of the drum 310; and, by controlling the rotation speed and axial length of the drum 310, the dwell time of the peat inside the drum 310 can be adjusted.

[0051] Furthermore, in this embodiment, in order to increase the heating area of ​​the peat when it tumbles inside the drum 310, the inner wall of the drum 310 is uneven; and the uneven inner wall can also slow down the movement speed of the peat inside the drum 310 and prolong the dwell time.

[0052] Furthermore, such as Figure 2 and Figure 3 As shown, a baffle ring 311 is provided on the inner wall of the input start end of the drum 310 to reduce the phenomenon of mud moving out from the input start end of the drum 310; thus, limited by the baffle ring 311, the mud can only move from the input start end of the drum 310 to the output end.

[0053] Furthermore, in this embodiment, to prevent the roller 310 from shifting due to a lack of fixation at the input end, such as... Figure 2 and Figure 3 As shown, the input start end face of the roller 310 is flush with the end face of the corresponding heating cylinder 320. At the same time, three stop blocks 322 are detachably provided on the end face of the heating cylinder 320. The stop blocks 322 extend along the radial direction of the heating cylinder 320 and abut against the input start end face of the roller 310. Thus, the stop blocks 322, the hot rotating shaft 360, and the second motor 330 cooperate to fix the axial position of the roller 310.

[0054] Furthermore, such as Figure 2 As shown, a plurality of ejection assemblies are evenly spaced along the circumferential direction on the side wall of the roller 310 corresponding to the end of the rotary cutting housing 230. Each ejection assembly has a spring 312 arranged in the radial direction of the roller 310 and a wedge block 313 disposed on the free end of the spring 312. The inclined surface of the wedge block 313 faces the output end of the roller 310. Thus, the mud falling from the end of the U-shaped guide section 232 will first fall onto the wedge block 313, causing the spring 312 to undergo instantaneous compression deformation. When the spring 312 recovers its deformation, it will push the mud off the wedge block 313, which is beneficial for mud dispersion. At the same time, since the inclined surface of the wedge block 313 faces the output end of the roller 310, the accumulation of mud at the wedge block 313 can be reduced, and the ejection direction of the mud can be roughly directed towards the output end of the roller 310. Furthermore, the ejection assemblies arranged in a ring at intervals can also prevent the mud from moving towards the input beginning of the roller 310.

[0055] Furthermore, such as Figures 1-4 As shown, an air cylinder 380 is also provided on the outside of the heating cylinder 320; the air cylinder 380 is arranged coaxially with the heating cylinder 320, and an air inlet 381 is provided at one end near the second motor 330; an air outlet pipe 382 is provided at one end of the air cylinder 380 near the rotary cutting shell 230, and the air blown out from the air outlet pipe 382 enters the drum 310; thus, on the one hand, the air cylinder can be used to isolate and protect the heating cylinder to prevent burns; on the other hand, the heat in the heating cylinder is used to simultaneously heat the air and then introduce it into the drum to accelerate the discharge of evaporated water vapor, accelerate the dehydration process, and at the same time reduce the impact of temperature fluctuations.

[0056] Furthermore, such as Figure 2 As shown, in order to improve the reliability of the connection between the drum 310 and the hot rotating shaft 360, a Y-shaped connecting frame 370 is also provided in the middle of the axial direction inside the drum 310. The hot rotating shaft 360 is extended and connected to each Y-shaped connecting frame 370. As a result, the number of connection points between the hot rotating shaft 360 and the drum 310 increases, and the operational stability is improved.

[0057] Furthermore, such as Figure 4 As shown, in order to facilitate the collection of dehydrated peat, a U-shaped discharge chute 390 is provided below the end of the heating cylinder 320; thus, the peat can be collected in the collection container below the support frame 100 through the U-shaped discharge chute 390.
