[0041] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a grate furnace incineration fly ash collection and purification device, which includes upper and lower components 200, including a filter element 201 arranged on the dust collector 101, a driving member 202 arranged on the inner side of the dust collector 101, and a release member 203 arranged on the filter element 201. Through the interaction between the filter element 201, the driving member 202 and the release member 203, the dust collector 101 can partially shake off the fly ash accumulated during long-term operation.

[0042] Specifically, the filter element 201 includes a first pair of fixed plates 201a arranged on the dust collector 101, the first pair of fixed plates 201a is composed of two pairs of fixed plates, the first pair of fixed plates 201a is horizontally arranged at the upper side of the entire dust collector 101, and the dust collector 101 is provided with a guide groove 201b on one side of the position corresponding to the first pair of fixed plates 201a. There are several guide grooves 201b, which are used to guide and assist the fixed plates to move under force. A first pair of filter bags 201c are fixedly connected to the upper side of the first pair of fixed plates 201a, and several first pairs of filter bags 201c are arranged on the upper side of the first pair of fixed plates 201a, which are used to filter the flue gas, so that fly ash will remain thereon.

The first pair of filter bags 201c are sleeved on the outer side of the support frame 201d, and the support frame 201d is provided for the first pair of filter bags 201c. A pair of filter bags 201c have a supporting function inside, and the support frame 201d is fixedly connected to the first pair of fixed plates 201a, so that the support frame 201d can support and unfold the first pair of filter bags 201c and play an auxiliary guiding role in the movement. The first pair of bottom plates 201e are fixedly connected to the other side of the first pair of filter bags 201c. The first pair of bottom plates 201e and the first pair of fixed plates 201a are correspondingly arranged, so that it is convenient to make the entire first pair of filter bags 201c droop and unfold, so as to facilitate the filtering of fly ash from flue gas, and when the first pair of bottom plates 201e is moved, the first pair of filter bags 201c can be driven to move unidirectionally on the support frame 201d and the first pair of fixed plates 201a, so that the first pair of filter bags 201c can be folded and then unfolded, and the fly ash on the first pair of filter bags 201c can be shaken off.

[0043] Furthermore, the driving member 202 includes a first rotating gear 202a rotatably connected to the dust collector 101, the first rotating gear 202a can be driven by a motor, a second rotating gear 202b fixedly connected on the other side of the dust collector 101, a transmission belt 202c meshingly connected to the second rotating gear 202b and the outer side of the first rotating gear 202a, and a driving block 202d fixedly connected to the transmission belt 202c, the cross-section of the driving block 202d is a "T" structure, when the driving block 202d moves to the middle position of the transmission belt 202c, the length of the driving block 202d does not exceed the width of the transmission belt 202c, so that when the driving block 202d moves to one side, half of the distance will exceed the width range of the transmission belt 202c itself, and the first rotating gear 202a is driven by the motor, so that the transmission belt 202c rotates under the action of the first rotating gear 202a and the second rotating gear 202b, and the driving block 202d will move accordingly.

[0044] Furthermore, the release member 203 includes a first locking plate 203a fixedly connected to the first pair of bottom plates 201e, the first locking plate 203a is used to fix the first pair of bottom plates 201e, the first pair of bottom plates 201e is composed of two bottom plates, and the first fixing block 203b fixedly connected to the first locking plate 203a, so that the movement of the first fixing block 203b will drive the movement of the first locking plate 203a and the first pair of bottom plates 201e, and will also make the first pair of filter bags 201c on the first pair of bottom plates 201e fold and move synchronously, the first fixing block 203b is a rectangular structure, and a first entry groove 203c with a triangular structure is provided on the outer surface of the first fixing block 203b, and the first entry groove 203c can make The driving block 202d moves into it, and the first fixed block 203b is provided with an unlocking groove 203d from top to bottom. The unlocking groove 203d makes one side of the first fixed block 203b exposed, and has a certain inclined structure, which is adapted to the driving block 202d, so that it is convenient for the driving block 202d to move out of the first fixed block 203b from the first entry groove 203c through the unlocking groove 203d. A first spring 203e is fixedly connected to the bottom side of the unlocking groove 203d, and a first unlocking block 203f is fixedly connected to one side of the first spring 203e. The first unlocking block 203f is forced to move in the unlocking groove 203d, and a corresponding groove 203g is provided on one side of the first unlocking block 203f. The first unlocking block 203f can be realized when the driving block 202d is driven. When the moving block 202d moves into the first entry slot 203c, it resists the unlocking slot 203d, so that the driving block 202d can drive the first fixed block 203b and the first pair of bottom plates 201e to move, and can be forced to move downward so that the corresponding slot 203g corresponds to the unlocking slot 203d, so that the resistance is released, so that the driving block 202d moves out of the first fixed block 203b, so that the first fixed block 203b moves in the opposite direction with the first pair of bottom plates 201e and the first pair of filter bags 201c, and the top side of the first fixed block 203b is fixedly connected to the second spring 203h, and the first pair of fixed plates 201a is fixedly connected to the first extension block 203i, the first extension block 203i is fixedly connected to the second spring 203h, and the second spring 20 3h is fixedly connected between the first fixed block 203b and the first extension block 203i. When the first fixed block 203b moves upward with the driving block 202d, it will squeeze the second spring 203h. When the driving block 202d stops driving the first fixed block 203b, the reverse force of the second spring 203h will accelerate the reverse movement of the first pair of bottom plates 201e and the first pair of filter bags 201c, so that the first pair of filter bags 201c can be folded first and then unfolded, so that the fly ash on the first pair of filter bags 201c can be shaken off. A first buckling column 203j is fixedly connected to one side of the first extension block 203i. The first unlocking block 203f moves with the movement of the first fixed block 203b, thereby contacting the first buckling column 203j.In this way, the first buckling column 203j will squeeze the first unlocking block 203f on the first fixed block 203b to make the corresponding groove 203g correspond to the unlocking groove 203d, so that the resistance is released, so that the driving block 202d moves out of the first fixed block 203b, so that the first fixed block 203b moves in the opposite direction with the first pair of bottom plates 201e and the first pair of filter bags 201c.

[0045] When in use, the first rotating gear 202a is driven by the motor to realize the movement of the driving block 202d. When the driving block 202d moves into the first entry groove 203c of the first fixed block 203b, due to the setting of the first unlocking block 203f, the continuous upward movement of the driving block 202d will cause the first pair of bottom plates 201e and the first pair of filter bags 201c to move upward. When the first buckling column 203j on the first extension block 203i on the first pair of fixed plates 201a squeezes the first unlocking block 203f, under the action of the first spring 203e, the first unlocking block 203f It will move downward in the unlocking slot 203d in the first fixed block 203b, so that the corresponding slot 203g on the first unlocking block 203f will correspond to the unlocking slot 203d, so that the driving block 202d will move out of the first fixed block 203b. Under the action of the second spring 203h, the first fixed block 203b will accelerate the reverse movement with the first pair of bottom plates 201e and the first pair of filter bags 201c, so as to realize the rapid reverse movement of the first pair of filter bags 201c and shake off the accumulated fly ash. This process not only improves the efficiency of fly ash treatment, but also reduces the need for manual cleaning and reduces maintenance costs.

[0046] Example 3, reference Figures 1 to 11 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a grate furnace incineration fly ash collection and purification device, which includes a reverse component 300, including an opposing piece 301 arranged on the dust collector 101, an inverting piece 302 arranged on the opposing piece 301, and an unlocking piece 303 arranged on the inverting piece 302. Through the interaction between the opposing piece 301, the inverting piece 302 and the unlocking piece 303, part of the fly ash in the dust collector 101 will be shaken off in a direction opposite to the movement direction of the upper and lower components 200, and the fly ash is shaken off in different directions and at different times in the entire dust collector 101, thereby optimizing the fly ash removal process. The fly ash shaking off inside the dust collector 101 is no longer an action in a single direction or a single time point, but becomes a complex process in multiple directions and multiple time points. This design not only improves the efficiency of fly ash shaking off, but also reduces the secondary deposition of fly ash inside the dust collector 101, thereby improving the effect of fly ash collection and reducing the difficulty and cost of fly ash treatment.

[0047] Specifically, the opposing piece 301 includes a second pair of fixed plates 301a movably connected to the guide groove 201b, a second pair of filter bags 301b are sleeved on the outer side of the support frame 201d fixedly connected by the second pair of fixed plates 301a, and a second pair of bottom plates 301c fixedly connected to the bottom side of the second pair of filter bags 301b. The structure of the entire opposing piece 301 is the same as the corresponding structure in the upper and lower components 200, except that the moving direction of the opposing filter bags is opposite, and they can move from top to bottom.

[0048] Furthermore, the inverting member 302 includes a second locking plate 302a fixedly connected to the upper side of the second pair of fixed plates 301a, a second fixed block 302b fixedly connected to the second locking plate 302a, a second entry groove 302c provided on the second fixed block 302b, an unlocking groove 203d also provided on the second fixed block 302b, a second unlocking block 302d movably connected to the unlocking groove 203d, a first spring 203e is also provided on the second unlocking block 302d, a corresponding groove 203g is also provided on the second unlocking block 302d, and an unlocking groove 203d is also provided on the second fixed block 302b. The position of the entire second fixed block 302b is fixed on the upper side and opposite to the position of the first fixed block 203b, so the positions of other structures thereon are also opposite.

[0049] Furthermore, the unlocking member 303 includes a second extension block 303a fixedly connected to the second pair of base plates 301c, a second buckling column 303b fixedly connected to the second extension block 303a, and a third spring 303c fixedly connected between the second fixed block 302b and the second extension block 303a, and the third spring 303c moves in the opposite direction due to the squeezing force from top to bottom.

[0050] When in use, when the driving block 202d moves to the reverse position, it moves with the second unlocking block 302d and contacts the second buckling column 303b, which will cause the second unlocking block 302d to move into the unlocking slot 203d, so that the corresponding slot 203g corresponds to the unlocking slot 203d. At this time, the driving block 202d will move away from the second fixed block 302b. Under the action of the third spring 303c, the second fixed block 302b and the second pair of filter bags 301b on the second locking block will move in the reverse direction at an accelerated speed, realizing the reverse folding movement of the second pair of filter bags 301b first downward and then upward, and also accelerating the shaking off of fly ash on the second pair of filter bags 301b.

[0051] There are two lower funnels 101a on the entire dust collector 101, and each lower funnel 101a has two upper and lower components 200 and a reverse component 300. In this way, the entire fly ash shaking off is no longer an action in a single direction or a single time point, but becomes a complex process in multiple directions and multiple time points. This design not only improves the efficiency of fly ash shaking off, but also reduces the secondary deposition of fly ash inside the dust collector 101, thereby improving the fly ash collection effect and reducing the difficulty and cost of fly ash treatment.
