Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a rotary kiln which is easy to clean and has high sealing performance. Background Art

[0002] Rotary kiln is a thermal equipment for calcining, roasting or drying granular and powdery materials. It is mainly used for calcining cement clinker in cement industry, calcining granular and powdery materials in refractory and ceramic industries, and drying various raw materials in the above industries. It is widely used for drying, dehydrating and roasting materials in chemical industry.

[0003] The rotary furnace can rotate forward and reverse, and has fast and slow drive devices. There is an extreme position for both forward and reverse rotation: the extreme position for forward rotation is the slag pouring position, and the extreme position for reverse rotation is the copper casting completion position. For the convenience of operation, oxidation, reduction, insulation, feeding, etc. are also set. When the furnace is feeding, pouring slag, oxidizing, and reducing, fast drive is used; when casting, slow drive is used. At the same time, in order to avoid accidents caused by sudden power outages when the rotary furnace is in a non-insulation position, an accident drive motor is also set to ensure that the rotary furnace safely rotates to the insulation position.

[0004] During the use of the rotary kiln, materials often stick to the wall, so a cleaning brush needs to be installed in the rotary kiln to clean the inner wall of the rotary kiln; however, in the prior art, the roller of the cleaning brush extends out of the outside of the furnace body and is connected to the driving member, and the roller of the cleaning brush is rotatably connected to the furnace body through a sealed bearing.

The guide columns 2211 are slidably connected to the guide grooves, and are used to guide and support the movement of the arc-shaped plates 221, thereby improving the operating stability of the entire device.

[0071] like Figures 3 to 5 As shown, the driving assembly includes a sleeve 214 , a lifting unit 215 and a driving unit 216 .

[0072] Among them, the sleeve 214 is slidably sleeved on the outer side of the shaft body; specifically, a plurality of equally spaced guide grooves are opened on the outer circumferential surface of the shaft body, and a guide slider slidably connected to the guide groove is fixedly provided on the inner circumferential surface of the sleeve 214; the guide groove and the guide slider cooperate to guide the movement of the sleeve 214, and have high stability.

[0073] The lifting unit 215 connects the sleeve 214 and the arc plate 221 ; the driving unit 216 is used to drive the sleeve 214 to slide horizontally along the shaft, thereby driving the lifting assembly to drive the arc plate 221 to move vertically.

[0076] The driving unit 216 drives the sleeve 214 to move horizontally, thereby driving the travel groove 2151 to slide horizontally, and then driving the circular gear 2153 and the ball screw 2154 to rotate, and then driving the first vertical sleeve 2155 to slide vertically and drive the arc plate 221 to rise or fall.

[0077] Specifically, the driving unit 216 includes a first horizontal sleeve 2161 , a first guide rod 2162 , an electromagnet sheet 2163 , and a third magnet block 2164 .

[0078] The first horizontal sliding sleeve 2161 is located in the guide sliding groove and is fixed to one end of the guide sliding block; one end of the first guide rod 2162 is fixedly connected to the second sealing plate 213, and the other end is slidably connected to the first horizontal sliding sleeve 2161, and the electromagnet sheet 2163 is installed at this end; the third magnet block 2164 is installed at the bottom of the first horizontal sliding sleeve 2161, and cooperates with the electromagnet sheet 2163 to drive the sleeve 214 to move.

[0080] In addition, in this embodiment, the driving unit 216 further includes a second horizontal sleeve 2165 , a second guide rod 2166 and a first cylindrical spring 2167 .

[0083] The working principle of this device is as follows:

[0084] In the initial state, the third magnet block 2164 is attracted to the electromagnet sheet 2163, and the arc plate 221 is closed (eg Figure 3 When the inside of the furnace body 1 needs to be cleaned, the magnetism of the electromagnet sheet 2163 is weakened by the control unit, and the sleeve 214 moves in a direction away from the electromagnet sheet 2163 under the action of the first cylindrical spring 2167, thereby driving the rack 2152 to drive the circular gear 2153 and the ball screw 2154 to rotate, thereby driving the first vertical sleeve 2155 to move vertically and drive the arc plate 221 to rise and unfold the scraper to fit the inner wall of the furnace body 1 (as shown in FIG. Figure 4 As shown), the driving member 3 is then started to drive the cleaning brush 2 to rotate to clean the inner wall of the furnace body 1.

[0085] It should be noted that, in this embodiment, sealing gaskets are provided between the sliding contact surfaces of the guide posts 2211 and the guide grooves where the four arc plates 221 are connected end to end, and between the contact surfaces of the arc sealing plates 25 and the arc plates 221 .
