Connecting rod assemblies 34 are hinged between the side ends of one end of each enclosing plate 231 in the sliding direction in each filtering part 23, the four connecting rod assemblies 34 are slidably arranged on the circular guide rail 33, and when the central shaft of the circular guide rail 33 is coincident with the central shaft of the rotating shaft of the air passage rotor 22, the connecting rod assemblies 34 can roll along the circumference of the circular guide rail 33; the connecting rod assembly 34 comprises two push-pull connecting rods 341 with one ends hinged on the two surrounding plates 231 in a one-to-one correspondence manner, the other ends of the two push-pull connecting rods 341 are jointly hinged with a hinge joint 342, a rolling shaft 343 is horizontally rotatably arranged on the hinge joint 342, the rolling shaft 343 is arranged in a rolling manner along the arc guide rail 333, and when the rolling shafts 343 of the two connecting rod assemblies 34 are positioned in the two avoidance guide rails 332 in a one-to-one correspondence manner and the annular guide rails 33 move up and down along with the driving frame 32, the avoidance guide rails 332 can avoid the rolling shafts 343 positioned in the two avoidance guide rails to vertically move.
In the production working process of the quicklime slaker, the dust intercepting and filtering mechanism 2 has two states, namely a dust removing working state and a rotary transposition state, and the whole dust removing working process is explained in detail by combining the two states.
In the dust removal working state, the four filter parts 23 are in a positive cross state, only one filter part 23 butted with the diversion bin 121 is in an actual dust removal state, the filter part 23 positioned right below the filter part 23 in the actual dust removal state is completely immersed in the water layer of the box 11, and the other two filter parts 23 are in horizontal positions and are also immersed in the water layer of the box 11, but are close to the liquid level. During operation, on the one hand, the filtering parts 23 in the actual dust removing state will remove dust from the introduced dust-containing steam, on the other hand, in this state, the cleaning driving mechanism 3 is in a continuous working state, under the reciprocating driving of the power part 31, the driving frame 32 will drive the circular ring guide rails 33 to do synchronous lifting motion therewith, the rolling shafts 343 in the two filtering parts 23 in the vertical direction are distributed in the two avoidance guide rails 332 in a one-to-one correspondence manner, so that the avoidance guide rails 332 can actively avoid the rolling shafts 343 to form vertical movement interference, the circular ring guide rails 33 will drive the rolling shafts 343 in the two filtering parts 23 in the horizontal position by the two circular arc guide rails 333 one-to-one, thereby driving the connecting rod assemblies 34 in the two filtering parts 23 in the horizontal position to do vertical constant amplitude swinging, and driving the two surrounding plates 231 in the reciprocating reverse sliding along the respective sliding grooves 2213 by the connecting rod assemblies, and during sliding, the rolling rollers 233 passively rotate under the resistance of the surrounding water layer, in addition, the rolling rollers 233 on the two surrounding plates can actively avoid the rolling shafts 343 to form vertical movement interference, the rolling shafts 233 can actively contact with each other, thus the dust can actively dissolve in the water layer, and the dust can be dissolved in the dust layer, and the dust can be actively deposited in the water layer.
Meanwhile, the two filter parts 23 at the horizontal position are cleaned by dust layers, and the rotary transposition motor 21 drives the air passage rotor 22 to rotate ninety degrees each time, namely, one of the two filter parts 23 at the horizontal position is cleaned for the first time, the other is cleaned for the second time, the filter part 23 cleaned for the second time is just at a vertical downward position in the suspension process of the rotary transposition in the last step, the filter part 23 is completely immersed in a water layer at the position, dust substances in the water layer are obviously easy to be deposited in the filter part 23 at the position again in a small amount, so that the cleanliness of the position switched to a dust removing state in the next rotation can be ensured through the second cleaning, and therefore, the efficient dust removing effect is maintained.
In the rotating transposition state, when the dust collection operation of the filtration parts 23 at the dust collection butting position is carried out for a certain time, dust gradually gathers in the rectangular channel, the air channel gradually becomes too narrow so as to influence the normal circulation of steam, and in addition, the dust accumulated on the bristles of the filtration rotating roller 233 gradually reaches saturation, so that the air channel rotor 22 is required to be driven to intermittently rotate by the rotating transposition motor 21, each filtration part 23 is enabled to rotationally shift by a quarter circle around the central axis of the air channel rotor 22 in the circumferential direction, the filtration parts 23 which finish dust collection can be conveniently cleaned, and meanwhile, the filtration parts 23 to be subjected to dust collection can be replaced; in the present embodiment, when the power unit 31 is in the suspended state, the connecting rod assembly 34 in the horizontal filter unit 23 is in the swing balanced state, and the four rolling shafts 343 are in the state of rolling along the circumference of the circular guide 33 when the circular guide 33 rotates with the air passage rotor 22, when the cleaning driving mechanism 3 is in the suspended state, the rotary transposition motor 21 can be started to transpose the four filter units 23, and after transposition is completed, the cleaning driving mechanism 3 can be restarted to continue cleaning.
Compared with the existing quicklime slaker with a dust removing function, the quicklime slaker with the dust removing function adopts a mode of directly introducing dust-containing steam into a water tank to carry out wet dust removal, in the dust removing structure provided by the invention, four interception and filtration components 23 which can be intermittently rotated are arranged as dust removing filter structures, in the actual dust removing working process, one interception and filtration component 23 is always in a dust removing working state, two interception and filtration components 23 are in a cleaning state, the interception and filtration structure arranged on the interception and filtration components 23 slows down the speed of steam circulation, the time of filtering and dust removing is prolonged, the contact area with steam is increased, the dust removing efficiency is greatly improved, in addition, the dust removing effect is greatly improved by rotating and rotating transposition, and the automatic cleaning is combined, so that the cleaning of the interception and filtration dust removing effects of the interception and filtration components 23 in the next dust removing process can be completed, and meanwhile, the accumulated dust substances can be transferred and released into a water layer through cleaning, so that the dust substances can be directly contacted with water instead of the existing mode of indirectly contacted with water through steam flow, and the full and efficient cleaning of dust can be ensured; in summary, the digester provided by the invention adopts the filter structure with improved design to intercept and filter dust, and realizes dust removal and filtration in a mode of matching with rotation transposition and synchronous cleaning with the dust removal process, so that the dust removal efficiency is improved, the dust removal effect is enhanced, and the high-efficiency dust removal sustainability is ensured.
