Abstract
Description
Technical Field
[0001] This utility model relates to the field of bentonite drying technology, and more specifically, to a rotary device for drying bentonite. Background Technology
[0002] Bentonite, also known as bentonite, soapstone, or bentonite rock, is a non-metallic mineral with montmorillonite as its main mineral component. Montmorillonite has a 2:1 crystal structure consisting of two silicon-oxygen tetrahedra sandwiching a layer of aluminum-oxygen octahedra, giving it unique physical and chemical properties. Bentonite is relatively moist after mining and requires drying.
[0003] A search revealed that utility model patent CN216308474U discloses a rotary device for drying bentonite. The rotary device includes: a base plate and support frames symmetrically arranged on the upper surface of the base plate; two rotating wheels rotatably connected to each support frame; a cylinder rotatably connected between the two rotating wheels; a stirring component comprising a support rod, a stirring rod, and a sleeve; one end of the support rod being fixedly connected to the inner wall of the cylinder; vertical rods arranged in an equidistant array on the support rod; the sleeve being installed at the lower end of the vertical rods; the stirring rod being fixedly connected to the bottom end of the sleeve; and a limiting component comprising a ring fixedly connected to the inner wall of the cylinder. This patent allows the stirring rod, fixed to the sleeve, to stir the bentonite inside the cylinder during rotation, breaking up clumps of clay and achieving a better drying effect.
[0004] However, the above-mentioned patent still has the following shortcomings: the position of the stirring rod is fixed, which makes it difficult to ensure that the bentonite will come into contact with the stirring rod, thus failing to guarantee the effect of crushing the bentonite; and the bentonite will generate a certain amount of dust when discharged, which will affect the surrounding environment if not treated. Therefore, we have proposed a rotary device for drying bentonite. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rotary device for drying bentonite.
[0006] To solve the above problems, the present invention adopts the following technical solution:

A rotary furnace cylinder is rotatably connected to the inner sides of the two rotating frames. A support column is fixedly connected to the top surface of the supporting inclined platform. A feed top cover is fixedly connected to the top of the support column. The end face of the feed top cover is rotatably connected to the top of an electric heating coil. A dust extraction mechanism is provided at the end of the supporting inclined platform. A blower mechanism and a feeding mechanism are provided at the end of the feed top cover. An electric heating coil is sleeved on the outer side of the rotary furnace cylinder. Multiple spiral plates are fixedly connected to the inner wall of the rotary furnace cylinder. Two connecting columns are fixedly connected to the bottom of the end face of the feed top cover. A support plate is fixedly connected to the ends of the two connecting columns. A third motor is fixedly mounted on the support plate. A rotating rod is fixedly connected to the output shaft of the third motor.

[0008] As a preferred embodiment of this utility model, the dust collection mechanism includes two support rods fixedly connected to one end of the support sloping platform, a filter box fixedly connected to the top of the two support rods, a sealing door hinged to the side of the filter box, a filter screen fixedly fitted inside the filter box, a dust collection pipe fixedly fitted to one end of the filter box, a dust collection hood fixedly connected to the end of the dust collection pipe, and an exhaust pump fixedly installed at the other end of the filter box, with the input end of the exhaust pump extending into the inner cavity of the filter box.
[0009] As a preferred embodiment of this utility model, the feeding mechanism includes a feeding cylinder fixedly sleeved on the feeding top cover, a storage cylinder fixedly connected to the top surface of one end of the feeding cylinder, a preheating cylinder fixedly connected to the outer side of the storage cylinder, a plurality of exhaust holes opened on the top surface of the preheating cylinder, an air guide pipe fixedly sleeved on the side of the preheating cylinder, the end of the air guide pipe being connected to the output end of the exhaust pump, a first motor fixedly installed on the end face of the feeding cylinder, the output shaft of the first motor extending into the inner cavity of the feeding cylinder and fixedly connected to a spiral conveying rod, the side of the spiral conveying rod being in contact with the inner wall of the feeding cylinder, and the end of the feeding cylinder being fixedly sleeved into the inner cavity of the rotary kiln cylinder.
[0010] As a preferred embodiment of this utility model, the blower mechanism includes a blower tube fixedly sleeved in the middle of the feed top cover, a filter cotton fixedly sleeved at one end of the blower tube, a blower fan fixedly installed in the inner cavity of one end of the blower tube, and multiple electric heating tubes fixedly installed in the inner cavity of the other end of the blower tube.
[0011] As a preferred embodiment of this utility model, a second gear is fixedly sleeved on the outer side of the rotary furnace cylinder, a second motor is fixedly installed on the side of one of the rotating frames, and a first gear is fixedly sleeved on the output shaft of the second motor, with the first gear and the second gear meshing with each other.
[0012] As a preferred embodiment of this utility model, a control panel is fixedly installed on the side of the supporting inclined platform.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] (1) In this utility model, the bentonite to be dried is introduced into the inner cavity of the rotary furnace cylinder by the feeding mechanism. At the same time, the third motor drives the rotating rod and the crushing knife to rotate. When the bentonite enters the inner cavity of the rotary furnace cylinder, it falls onto the crushing knife. The crushing knife completely crushes the bentonite to ensure the quality of subsequent drying of the bentonite. When the rotary furnace cylinder rotates, it drives the spiral plate to rotate. The spiral plate stirs the bentonite to ensure that the bentonite is completely dried.
[0015] (2) In this utility model, when bentonite falls from the bottom of the rotary kiln, the suction pump is used to generate suction force in the dust hood. The suction force of the dust hood is used to draw the dust generated when the bentonite falls into the inner cavity of the filter box. The filter screen is used to filter and intercept the dust, thus realizing the function of treating the dust generated when the bentonite falls. The filtered hot air enters the inner cavity of the preheating cylinder through the air guide pipe, which generates heat on the storage cylinder and preheats the bentonite in the inner cavity of the storage cylinder, thus realizing the recovery and utilization of the residual hot air from the drying of bentonite.

[0041] Working Principle: In operation, the bentonite to be dried is first placed into the inner cavity of the storage cylinder 29, allowing it to enter the inner cavity of the feeding cylinder 28. The first motor 31 is started, driving the screw conveyor 32 to rotate. The screw conveyor 32 pushes the bentonite into the inner cavity of the rotary furnace cylinder 3. Simultaneously, the third motor 12 is started, driving the rotating rod 13 and the crusher 14 to rotate. The crusher 14 crushes the bentonite entering the inner cavity of the rotary furnace cylinder 3. Additionally, the second motor 35 is started, driving the first gear 36 to rotate. The meshing transmission between the first gear 36 and the second gear 37 drives the rotary furnace cylinder 3 to rotate, causing the bentonite inside the rotary furnace cylinder 3 to rotate and gradually move forward and downward.

Fan 26 draws outside air into the inner cavity of the blower 24, and the air is heated by heating element 25, allowing the hot air to enter the inner cavity of the rotary furnace 3 for drying the bentonite. Then, as the bentonite moves within the rotary furnace 3, it is agitated by spiral plate 38 to ensure the quality of the drying process. The dried bentonite is discharged from the bottom of the rotary furnace 3. Finally, the exhaust pump 22 is activated to draw air from the inner cavity of the filter box 17, using the filter... The negative pressure inside the chamber 17 causes the suction pipe 19 and the suction hood 20 to generate suction. The suction of the suction hood 20 is used to draw the dust generated when the bentonite falls into the inner chamber of the filter chamber 17. The filter screen 21 filters and traps the dust.
