DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0019] The coal slime drying device of the utility model embodiment is described below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 2 As shown, the coal slime drying device according to the embodiment of the utility model may include a drying box 10, a conveyor belt 30, a pressure roller 40 and a drying mechanism.

[0021] An inlet 11 and an outlet 12 are respectively disposed on both sides of the drying box 10 , a support plate 20 is disposed inside the drying box 10 , and mounting frames 21 are disposed on both sides of the support plate 20 .

[0022] The conveyor belt 30 can be slidably mounted on the outer side of the support plate 20, and two driving rollers 31 symmetrically arranged on the inner side of the conveyor belt 30 are respectively arranged on the mounting frame 21, and driving components 311 are arranged on the driving rollers 31. A rolling seat 32 is arranged in the middle of the conveyor belt 30, and baffles 33 and chains 34 are arranged on both sides of the rolling seat 32 in sequence.

[0023] It can be understood that the two baffles 33 can block the coal slime on the inner rolling seat 32 so that all the coal slime can be rolled by the pressing roller 40 .

[0024] It should be noted that the driving component 311 described in this embodiment can be a reduction motor, a servo motor, etc. The driving component 311 can drive the driving roller 31 connected thereto to rotate, and the two driving rollers 31 can rotate synchronously and in the same direction, so that the two driving rollers 31 can drive the conveyor belt 30 to transport the coal slime to the outlet 12.

[0025] The pressure roller 40 is movably connected to the inner walls of the drying box 10 on both sides through the rotating shafts 41 on both sides. The pressure roller 40 is arranged on the upper side of the conveyor belt 30 and abuts against the rolling seat 32. The outer side of the rotating shaft 41 is sleeved with a sprocket 42 meshing with the corresponding chain 34. The rotating shaft 41 is arranged above the baffle 33.

[0026] It is understandable that, when the baffle 33 rotates with the conveyor belt 30 , the chain 34 drives the sprocket 42 on the rotating shaft 41 , so that the sprocket 42 can drive the pressure roller 40 to rotate.

[0027] It should be noted that at least two pressing rollers 40 described in this embodiment are arranged side by side, the number of pressing rollers 40 can be set as needed, and the conveyor belt 30 can drive multiple pressing rollers 40 to rotate synchronously during the transmission process, thereby improving the rolling effect on the coal slime, ensuring the uniform thickness of the coal slime, and accelerating the drying of the coal slime.

[0028] The drying mechanism includes a hot air pipe 51 and a heating element 52 , wherein one end of the hot air pipe 51 extends into the interior of the drying box 10 through a through hole 13 on the drying box 10 , and the heating element 52 is detachably arranged in an installation cavity 401 inside the pressure roller 40 .

[0029] It should be noted that the other end of the hot air duct 51 described in this embodiment can be connected to an external heating device, so that the hot air duct 51 can pass hot air into the drying box 10, and the heating element 52 can be a resistance heater, an electromagnetic induction heater, a steam heater, etc. The heating element 52 can heat the pressure roller 40.

[0030] Specifically, in the actual process of drying the coal slime, the relevant personnel first throw the coal slime from the inlet 11 onto the rolling seat 32 , and the coal slime moves toward the outlet 12 under the conveyance of the conveyor belt 30 .

[0031] As the coal slime moves in the drying box 10, the hot air duct 51 heats and dries the coal slime, and at the same time, the pressing roller 40 rotates along with the conveyor belt 30. The pressing roller 40 can crush the coal slime, and the thickness of the coal slime after crushing is consistent, thereby ensuring the uniformity and stability of the coal slime during the drying process, allowing the coal slime to be fully exposed to the hot air inside the drying box 10, ensuring that the coal slime is thoroughly dried, and the drying quality of the coal slime is guaranteed, thereby improving the efficiency and reliability of the entire coal slime drying process.

[0032] After being dried, the coal slime can be discharged from the drying box 10 through the outlet 12 .

[0033] In one embodiment of the present invention, Figure 2 As shown, a plurality of rolling grooves 321 are evenly arranged on the outer surface of the rolling seat 32 , and a rolling wheel 411 matching with the rolling grooves 321 is arranged on the pressure roller 40 .

[0034] It can be understood that the provided rolling groove 321 can increase the contact area of ​​the rolling wheel 411 with the coal slime, which helps to fully roll the coal slime.

[0035] In one embodiment of the present invention, Figure 1 As shown, a heat conducting layer 402 and a contact layer 403 are sequentially arranged outside the mounting cavity 401 .

[0036] It should be noted that the heat conductive layer 402 described in this embodiment may be a ceramic coating, a special coating (such as a polytetrafluoroethylene coating), a metal heat conductive layer 402, etc. The provided heat conductive layer 402 can ensure that the pressure roller 40 is uniformly heated as a whole.

[0037] It should be noted that the contact layer 403 described in this embodiment can directly contact the coal slime, and the contact layer 403 can be made of materials such as stainless steel, nickel alloy, special coating (such as polytetrafluoroethylene), ceramics, etc. These materials can effectively avoid adhesion to the coal slime during the hot pressing process of the coal slime, ensuring the use effect and life of the pressing roller 40.

[0038] In one embodiment of the present invention, Figure 1 As shown, a scraper 60 is disposed on one side of the pressure roller 40, and the scraper 60 is disposed on the inner wall of the drying box 10, and the scraper 60 is disposed on the side of the pressure roller 40 away from the inlet 11. It can be understood that the scraper 60 can scrape off the coal slime remaining on the pressure roller 40.

[0039] In summary, the coal slime drying device of the embodiment of the utility model can crush the coal slime transported on the conveyor belt through the introduced pressure roller, so as to control the thickness of the coal slime. This process ensures the uniformity and stability of the coal slime during the drying process, so that the coal slime can be fully exposed to the hot air, ensuring that the coal slime is thoroughly dried. The drying quality of the coal slime is guaranteed, thereby improving the efficiency and reliability of the entire coal slime drying process.
