When the motor drives the circulating fan blades 12 to rotate, the circulating fan blades 12 can promote the uniform dispersion of hot air in the ash bin body 1 on one hand, and can remove dust from suspended dust on the other hand, and simultaneously accelerate the hot air to flow rapidly towards the sliding screen 63.
The implementation principle of the pre-cooling system of the warehouse top dust remover 4 in the first embodiment of the application is as follows: the dry coal ash is stored in the ash storage body 1, the ash storage gasification system heats and stirs the dry coal ash, at the moment, the hot air in the ash storage body 1 rises, and the rising hot air reaches the sliding screen 63 after being filtered and dedusted by the filter plate 13 and the circulating fan blades 12. The heat in the hot air is conducted to the bending piece through the fixed cylinder 641, when the temperature of the hot air is lower than the set temperature range, the bending piece is not deformed, at the moment, the mesh holes on the sliding screen 63 are communicated with the mesh holes on the second ventilation screen 62, and the mesh holes on the first ventilation screen 61 are blocked by the sliding screen 63, so that the hot air lower than the set range flows to the dust remover 4 after entering the normal temperature chamber 3;
when the temperature of the hot air is between the set temperature range values, the bending piece stretches slightly, at the moment, the abutting point of the push rod 643 and the abutting rod 642 moves along the inclined guide surface 7 from the tip end of the abutting rod 642 to the direction close to the sliding screen 63, so that the abutting rod 642 and the sliding screen 63 are pushed to slide towards the direction close to the first ventilation screen 61, the mesh on the sliding screen 63 is in overlapping communication with the mesh on the first ventilation screen 61, the mesh on the sliding screen 63 is also in overlapping communication with the mesh on the second ventilation screen 62, and one part of the hot air is cooled and the other part of the hot air is not cooled; the two air flows are converged in the mixing chamber 10, after the temperature neutralization for a certain time, the neutralized air flows to the dust remover 4 rapidly under the action of the fan blades 11;
when the temperature of the hot air is higher than the set temperature range, the bending piece is heated and then stretched, so that the abutting rod 642 is pushed to lift and slide in the fixed cylinder 641, the sliding screen 63 is pushed to slide, the mesh on the sliding screen 63 is communicated with the mesh on the first ventilation screen 61, and the mesh on the second ventilation screen 62 is blocked by the sliding screen 63, so that the hot air higher than the set range enters the cooling chamber 2 and flows to the dust remover 4 after being cooled by the cooling component 5.
Embodiment two:
the difference between the second embodiment and the first embodiment is that, referring to fig. 5, the temperature-sensing driving member 644 includes a screw rod 17 rotatably installed in the fixed cylinder 641, a motor 16 for driving the screw rod 17 to rotate, and a temperature-sensing processor 15 installed on the outer side wall of the fixed cylinder 641, and the temperature-sensing processor 15 is electrically connected with the motor 16; the length direction of the screw rod 17 is consistent with the sliding direction of the abutting rod 642, and a threaded through hole for the screw rod 17 to penetrate through is formed in the big end of the abutting rod 642; a guide rod 18 is also installed in the fixed cylinder 641, the guide rod 18 is arranged in parallel with the screw rod 17, and the big end of the abutting rod 642 is slidably sleeved on the guide rod 18. The temperature sensing processor 15 can perform sensing identification on the temperature of the hot air, and the temperature sensing processor 15 can control the number of turns of the motor 16 rotating forward/backward according to the temperature of the hot air, so that the screw rod 17 is driven to rotate, the length of the abutting rod 642 extending out of the fixed cylinder 641 is adjusted, and the position adjustment of the sliding screen 63 is completed.
The implementation principle of the pre-cooling system of the warehouse top dust remover 4 in the second embodiment of the application is as follows: the motor 16 is zeroed first so that the lengths of the springs 8 on both sides of the sliding screen 63 are the same at normal temperature, and the push rod 643 contacts the inclined guide surface 7. When the hot air diffuses to the temperature sensing processor 15, the temperature sensing processor 15 firstly recognizes the temperature of the hot air, then transmits the signal to the motor 16 to drive the motor 16 to rotate fixedly, and the motor 16 drives the screw rod 17 to rotate, so that the abutting rod 642 stably stretches out of the fixed cylinder 641 under the combined action of the screw rod 17 and the guide rod 18, and the length of the abutting rod 642 stretching out of the fixed cylinder 641 is constant. In the process that the abutting rod 642 extends out of the fixed cylinder 641, the abutting rod 642 drives the sliding screen 63 to horizontally slide under the combined action of the pushing rod 643 and the inclined guide surface 7, so that the opening and closing of the air inlet of the cooling chamber 2 or the normal temperature chamber 3 are controlled, and hot air with excessive temperature enters the cooling chamber 2 and flows to the dust remover 4 for dust removal treatment after being cooled by the cooling component 5; the hot air with the heat resistance value lower than that of the dust remover 4 enters the normal temperature chamber 3 and flows to the dust remover 4 for dust removal treatment. Under the condition of ensuring that the dust remover 4 is not damaged, the energy waste caused by the fact that all hot air is cooled by the cooling component 5 is avoided as much as possible.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
