[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0042] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0043] Example 1, referring to Figure 1 and Figure 2 The first embodiment of the present invention provides a municipal solid waste incineration fly ash treatment device, which includes an ash discharge unit 100 and an ash removal unit 200.

[0044] The ash removal unit 100 includes an air inlet pipe 101 and an air outlet pipe 102, a junction pipe 103 disposed between the air inlet pipe 101 and the air outlet pipe 102, and an ash accumulation chamber 104 disposed at the bottom of the junction pipe 103.

[0045] The dust removal unit 200 includes a drive assembly 201 disposed outside the manifold 103, an installation assembly 202 disposed inside the manifold 103 and connected to the drive assembly 201, and a filter assembly 203 disposed on the installation assembly 202.

[0046] The drive assembly 201 includes a drive shaft 201a rotatably disposed in the manifold 103, a support plate 201b disposed on the manifold 103, and a drive motor 201c disposed on the support plate 201b and connected to the drive shaft 201a. The mounting assembly 202 is made of a cross-shaped component disposed at the end of the drive shaft 201a. The filter assembly 203 is made of filter plates mounted at the end of the cross-shaped component, with gaps between the multiple filter plates.

[0047] The process is as follows: the drive motor 201c drives the mounting assembly 202 and the filter assembly 203 to rotate in the manifold 103. When the filter assembly 203 rotates through the connection between the inlet pipe 101 and the outlet pipe 102 and the manifold 103, it filters the fly ash that enters and passes through the inlet pipe 101. At the same time, the filtered fly ash can fall off as the filter assembly 203 rotates and finally fall from the gap in the filter assembly 203 into the ash collection chamber 104 for storage. When the filter assembly 203 passes through the connection between the inlet pipe 101 and the outlet pipe 102 and the manifold 103, the fly ash will pass through the filter assembly 203 plate in the opposite direction, performing a reverse cleaning of the filter assembly 203 and increasing the service life of the filter assembly 203.

[0048] Example 2, refer to Figures 2-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: the mounting assembly 202 includes a mounting shaft 202a rotatably disposed inside the manifold 103 and connected to the drive assembly 201, four support tubes 202b disposed on the mounting shaft 202a, and a connecting column 202c elastically disposed in the support tubes 202b, the connecting column 202c being connected to the inside of the support tubes 202b by a spring; the filter assembly 203 is connected to the connecting column 202c, wherein the mounting shaft 202a is fixed to the drive shaft 201a.

[0049] The filter assembly 203 has four components, which are respectively connected to four connecting posts 202c. The filter assembly 203 includes a mounting bracket 203a disposed at the end of the connecting post 202c, an arc-shaped mounting frame 203b disposed on the outside of the mounting bracket 203a, and a filter screen 203c disposed on the mounting frame 203b. There is a gap between each two adjacent mounting frames 203b.

[0050] The filter screen 203c rotates through the connection between the air inlet pipe 101 and the manifold 103, as well as the connection between the air outlet pipe 102 and the manifold 103. The drive motor 201c drives the drive shaft 201a and the mounting shaft 202a to rotate, thereby driving the four mounting frames 203b to rotate. When the mounting frames 203b pass through the connection between the air inlet pipe 101 and the air outlet pipe 102 and the manifold 103, the filter screen 203c will filter the fly ash that enters and passes through the air inlet pipe 101.

[0051] Furthermore, the ash removal unit 200 also includes a sliding component 204 disposed on the filter component 203; the ash discharge unit 100 is provided with a limiting component 205, which cooperates with the sliding component 204.

[0052] The limiting component 205 includes a sliding groove 205a disposed at both ends of the manifold 103, an arc-shaped frame 205b disposed in the manifold 103 and connected to the sliding groove 205a, protrusions 205c disposed at equal intervals in the arc-shaped frame 205b, and an extrusion plate 205d disposed in the sliding groove 205a and located on one side of the air inlet pipe 101.

[0053] The sliding component 204 includes a limiting block 204a disposed at the bottom of the mounting frame 203b, the limiting block 204a being inserted into the sliding groove 205a; the limiting block 204a cooperates with the extrusion plate 205d and the protrusion 205c, and the contact surface is an inclined surface.

[0054] like Figure 5 As shown, the connection point between the air inlet pipe 101 and the manifold pipe 103 is designated as position one m, the top of the manifold pipe 103 is designated as position two n, the connection point between the air outlet pipe 102 and the manifold pipe 103 is designated as position three h, and the connection point between the manifold pipe 103 and the ash accumulation chamber 104 is designated as position four k. The system begins operation when the four mounting frames 203b are in four different positions. At position one (m), the limiting block 204a on the mounting frame 203b abuts against the extrusion plate 205d, compressing the spring. This causes the mounting frame 203b to separate from the inner wall of the manifold 103 at the connection point between the mounting frame 203b and the air inlet pipe 101. Fly ash then enters the manifold 103 through the gap between the mounting frame 203b and the air inlet pipe 101, passes through the filter screen 203c at position three (h), and exits through the air outlet pipe 102. As the mounting shaft 202a rotates, the mounting frame 203b at position one (m) will re-adhere to the inner wall of the manifold 103 after leaving the extrusion plate 205d. Upon reaching position three (h) after passing position two (n), a small amount of fly ash will escape from between the two mounting frames 203b. The fly ash is filtered out and falls from the filter screen 203c into the ash collection chamber 104 through the gap between the two mounting frames 203b. The limiting block 204a is located in the middle of the mounting frame 203b. The limiting block 204a will only contact the extrusion plate 205d when the mounting frame 203b is fully aligned with position 1m. Only then will the mounting frame 203b separate from the inner wall of the manifold 103. When the mounting frame 203b just enters position 1m, the fly ash will enter the manifold 103 through the gap between the two mounting frames 203b and the gap between the previous mounting frame 203b and the inner wall of the manifold 103. The full alignment of the mounting frame 203b with position 1m means that the mounting frame 203b completes the coverage of the connection between the air inlet pipe 101 and the manifold 103.

[0055] Furthermore, when the mounting frame 203b reaches position four k, the limiting block 204a abuts against the protrusion 205c, which squeezes the mounting frame 203b away from the inner wall of the manifold 103 and simultaneously compresses the first spring. After the limiting block 204a passes through the protrusion 205c, under the elastic force of the first spring, the mounting frame 203b quickly pops out and contacts the inner wall of the manifold 103, causing an impact, thereby shaking off the fly ash in the filter screen 203c, achieving a dust removal effect. There are multiple protrusions 205c, and the mounting frame 203b will undergo multiple vibrations when it passes through position four k. When the mounting frame 203b is fully aligned with position four k, the limiting block 204a will contact the first protrusion 205c. When the mounting frame 203b is not completely separated from position three h, the mounting frame 203b will not contact the protrusion 205c and vibrate.

[0056] The remaining structure is the same as that in Example 1.

[0057] The usage process is as follows: As the drive motor 201c works, the mounting frame 203b rotates in the manifold 103 along with the rotation of the drive shaft 201a and the mounting shaft 202a. The mounting frame 203b drives the filter plate to pass through position one m, position two n, position three h and position four k in sequence. Multiple mounting frames 203b can be distributed in the four positions. When the mounting frame 203b passes through position one m, it does not affect the entry of fly ash. When the mounting frame 203b enters position four k, it can clean the fly ash and increase the service life of the filter screen 203c.

[0058] Example 3, referring to Figure 6 and Figure 7 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the ash removal unit 200 further includes a compensation component 206. The compensation component 206 includes a receiving groove 206a disposed at the end of the mounting frame 203b, a sealing plate 206b slidably disposed in the receiving groove 206a, a connecting pipe 206c disposed in the mounting frame 203b and communicating with the receiving groove 206a, a piston 206d slidably disposed in the cylinder of the connecting pipe 206c, and a connecting rope 206e disposed between the piston 206d and the sealing plate 206b.

[0059] The sealing plate 206b mates with the adjacent mounting frame 203b; two connecting pipes 206c and two sliding assemblies 204 are provided, and the ends of the two connecting pipes 206c are respectively connected to the two sliding assemblies 204.

[0060] The sliding assembly 204 includes a mounting tube 204b disposed on the mounting frame 203b, a piston column 204c elastically disposed in the mounting tube 204b, the piston column 204c and the mounting tube 204b being connected by a spring, and a limiting block 204a disposed at the bottom of the piston column 204c; the limiting block 204a cooperates with the extrusion plate 205d and the protrusion 205c, and the contact surface is inclined; an expansion groove 205e is provided in the sliding groove 205a near the air outlet duct 102; one end of the arc-shaped frame 205b is connected to the expansion groove 205e.

[0061] Furthermore, the top area of ​​the limiting block 204a is larger than the bottom area of ​​the piston column 204c. The limiting block 204a cooperates with the mounting frame 203b. When the limiting block 204a is squeezed and moved, it will abut against the mounting frame 203b when it moves to the mounting frame 203b to limit the movement and prevent the spring from being squeezed and damaged.

[0062] When the limiting block 204a enters the expansion groove 205e, it will pop out under the elastic force of the second spring, and at the same time, it will suck in the connecting pipe 206c, causing the piston 206d to move. The sealing plate 206b will be pulled and retracted into the receiving groove 206a through the connecting rope 206e. When the limiting block 204a leaves the expansion groove 205e, the limiting block 204a will be squeezed and abut against the mounting frame 203b for limitation. At the same time, the piston column 204c will inject air from the mounting pipe 204b into the connecting pipe 206c and push the piston 206d to move, causing the connecting rope 206e to loosen. The sealing plate 206b is made of metal. Under the action of gravity, the sealing plate 206b will extend out of the receiving groove 206a or continue to retract into the receiving groove 206a. When it extends out of the receiving groove 206a, it will straighten the connecting rope 206e.

[0063] One end of the connecting pipe 206c is connected to the top of the mounting pipe 204b, and the inner diameter of the mounting pipe 204b is larger than the inner diameter of the connecting pipe 206c. The piston rod 204c can drive the piston 206d to move a longer distance by moving a small distance in the mounting pipe 204b.

[0064] like Figure 7As shown, the connection point between the air inlet pipe 101 and the manifold pipe 103 is designated as position one m, the top of the manifold pipe 103 is designated as position two n, the connection point between the air outlet pipe 102 and the manifold pipe 103 is designated as position three h, and the connection point between the manifold pipe 103 and the ash accumulation chamber 104 is designated as position four k. The system begins operation when the four mounting frames 203b are in their respective positions. At position one m, the limiting block 204a on the mounting frame 203b abuts against the extrusion plate 205d, compressing the spring one. This separates the mounting frame 203b from the inner wall of the manifold pipe 103 at the connection point between the air inlet pipe 101 and the manifold pipe 103. At this point, fly ash enters the manifold pipe 103 from the gap between the mounting frame 203b and the air inlet pipe 101, passes through the filter screen 203c at position three h, and is discharged from the air outlet pipe 102.

[0065] When the mounting frame 203b at position one m rotates with the mounting shaft 202a, it will re-fit against the inner wall of the manifold 103 after leaving the extrusion plate 205d, and simultaneously enter position two n. When the mounting frame 203b reaches position two n and enters position three h, the sealing plate 206b in the mounting frame 203b will extend under the action of gravity and contact the previous mounting frame 203b, eliminating the gap between them. When it just enters position three h, no fly ash will be discharged from the gap. When the mounting frame 203b is fully in position threeh, the limiting block 204a enters the expansion groove 205e. At this time, the sealing plate 206b retracts into the receiving groove 206a, and the gap between this mounting frame 203b and the previous mounting frame 203b opens, allowing the fly ash filtered in this mounting frame 203b to pass through the gap and enter the ash accumulation chamber 104. When the mounting frame 203b is fully in position threeh, it means that the mounting frame 203b completely covers the connection between the manifold 103 and the air outlet 102.

[0066] When the mounting frame 203b is fully in position 4k, the limiting block 204a contacts the arc frame 205b, and the limiting block 204a is compressed. At this time, the connecting rope 206e loosens, and the sealing plate 206b is compressed into the receiving groove 206a under the action of gravity. When the mounting frame 203b has just entered position 1m, fly ash will enter from the gap between the two mounting frames 203b and the gap between the previous mounting frame 203b and the inner wall of the manifold 103. In pipe 103, when the mounting frame 203b passes through position fourk, the limiting block 204a abuts against the protrusion 205c, which squeezes the mounting frame 203b to separate from the inner wall of the manifold 103. At the same time, the spring is compressed. After the limiting block 204a passes through the protrusion 205c, under the elastic force of the spring, the mounting frame 203b quickly pops out and contacts the inner wall of the manifold 103, and impacts it, thereby shaking off the fly ash in the filter screen 203c, achieving a dust removal effect.

[0067] The remaining structure is the same as that in Example 2.

[0068] The usage process is as follows: As the drive motor 201c operates, the mounting frame 203b rotates in the manifold 103 along with the rotation of the drive shaft 201a and the mounting shaft 202a. The mounting frame 203b drives the filter plate to pass through position one m, position two n, position three h, and position four k in sequence. Multiple mounting frames 203b can be distributed in all four positions. When the mounting frame 203b passes through position one m, it does not affect the entry of fly ash. When the mounting frame 203b enters position four k, it can clean the fly ash and increase the service life of the filter screen 203c. At the same time, the sealing plate 206b can extend to eliminate the gap between two mounting frames 203b when the mounting frame 203b just enters position three h, and can retract when the mounting frame 203b has fully entered position three h, without affecting the discharge of fly ash.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
