Description

Technical Field

[0001] This invention relates to the field of dry slag discharge buffer hopper technology, and more particularly to an online adjustment device for the graded discharge pipe of a dry slag discharge hopper elevator. Background Technology

[0002] The dry ash discharge buffer hopper uses an angled connection. In this case, there is a "dead corner" when the waste ash from boiler combustion passes through the buffer hopper. After a long period of accumulation, secondary combustion and coking of the accumulated ash will occur. During the ash flow process, it enters the bucket elevator box, causing hard damage, deformation, and tearing to the hopper. Secondly, the bucket elevator buffer hopper is connected to the box inlet at a non-90° angle. When the waste ash enters the bucket elevator hopper, it cannot be in the center of the hopper. Over time, this causes one side of the chain to be unbalanced, resulting in severe damage to the chain, head wheel, and bearings on the stressed side. It also makes it inconvenient to distinguish and discharge large and small particles of waste ash. Summary of the Invention

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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. Example

[0027] Reference Figures 1-3 According to embodiment 6, the first embodiment of the present invention provides an online adjustment device for the grading of the material discharge pipe of a dry slag discharge bucket elevator. This device includes a pipe body mechanism 100, a processing mechanism 200, and an adjustment mechanism 300.

[0028] The tube body mechanism 100 includes a discharge tube 101, an inlet 102 opened at one end of the discharge tube 101, an outlet 103 provided at the other end of the discharge tube 101, a partition channel 104 provided in the inner cavity of the discharge tube 101, and a fixing block 105 provided at one end of the discharge tube 101.

[0029] During use, the processing mechanism 200, installed in the discharge pipe 101 to separate large and small particles of material, includes a support component 201 disposed in the inner cavity of the discharge pipe 101 between the inlet 102 and the outlet 103, a drive component 202 disposed at one end of the support component 201, and a stirring component 203 that cooperates with the drive component 202 and is connected to the support component 201.

[0030] When the material falls from the inlet 102 into the discharge pipe 101, it first falls onto the stirring component 203. Under the action of the material's own weight, it presses the stirring component 203, causing the stirring component 203 to move towards the support component 201. This allows the drive component 202 on the support component 201 to effectively drive the moving stirring component 203 to rotate. At this time, the stirring component 203 will cause the material, so that small particles fall by their own weight, allowing them to sink to the bottom and be filtered out above the stirring component 203. Large particles remain above it. As the stirring component 203 continues to descend, the unfiltered large particles will be discharged through the separator 104.

[0031] Furthermore, the adjustment mechanism 300 is disposed in the discharge port 103 for adjusting the discharge amount. It includes a first barrier 301 disposed on one side of the inner surface of the discharge port 103, a second barrier 302 disposed on the other side of the inner surface of the discharge port 103 and cooperating with the first barrier 301, and an adjustment component 303 for adjusting the angle of the second barrier 302.

[0032] By adjusting component 303, the angle of the second barrier 302 can be changed, so that the opening between the second barrier 302 and the first barrier 301 is constantly changed, effectively changing and adjusting the drop point of the material when it is discharged from the bucket elevator slag hopper. Example

[0033] Reference Figures 1-4 6 is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the support component 201 includes a support block 201a fixed to the inner wall of the discharge pipe 101 and a support column 201b disposed on the top of the support block 201a; the drive component 202 includes a compression spring 202a fixed to one end of the support column 201b, a twisted rod 202b disposed on the support column 201b, and a connecting ring 202c penetrated by the twisted rod 202b.

[0034] Compared to Embodiment 1, the twisted rod 202b is further fitted inside the compression spring 202a, and the other end of the compression spring 202a is fixed to the outer surface of the connecting ring 202c. That is, when the material falls onto the stirring assembly 203 and increases in weight, the stirring assembly 203 presses down on the compression spring 202a through the connecting ring 202c. As the weight increases, the pressure on the compression spring 202a increases, causing the stirring assembly 203 to descend. When it is no longer under pressure, the compression spring 202a springs up again.

[0035] During use, the stirring assembly 203 includes a dispersing disk 203a with its bottom end penetrated by a support column 201b, a first guide rod 203b disposed on the top of the dispersing disk 203a, and a stirring component 203c disposed on the outer surface of the first guide rod 203b; wherein, the first guide rod 203b limits the connecting ring 202c, and both are limited to rotation, and a material discharge hole 203a-1 is provided on the outer surface of the dispersing disk 203a.

[0036] When the material falls onto the dispersing disc 203a and exerts its weight on the dispersing disc 203a, small particles of material will fall through the discharge hole 203a-1 into the discharge port 103, while large particles of material are blocked on the dispersing disc 203a, causing the weight of the dispersing disc 203a to continuously increase.

[0037] The inner surface of the first guide rod 203b is fixedly provided with a protrusion 203b-1, and the protrusion 203b-1 cooperates with the twist rod 202b, and the twist rod 202b can slide in the first guide rod 203b.

[0038] Furthermore, the stirring assembly 203 includes a first stirring paddle 203c-1, a second stirring paddle 203c-2, and a third stirring paddle 203c-3 respectively disposed on the outer surface of the first guide rod 203b. One end of the third stirring paddle 203c-3 is fixedly connected to a telescopic rod 203c-4, and one end of the telescopic rod 203c-4 is provided with a scraper 305c-5, which is in contact with the conical surface of the inner surface of the discharge pipe 101.

[0039] As the weight of the dispersing disc 203a increases, the first guide rod 203b descends due to its fixed connection with the first guide rod 203b. This causes the protrusion 203b-1 on the lower sleeve of the first guide rod 203b to engage with the spiral surface of the twisted rod 202b, allowing the first guide rod 203b to rotate on the connecting ring 202c along the spiral surface. This, in turn, causes the first stirring paddle 203c-1, the second stirring paddle 203c-2, and the third stirring paddle 203c-3 to rotate and stir. Through stirring, the small particles above continuously fall through the gaps between the large particles to the bottom, where they are filtered by the discharge hole 203a-1.

[0040] Meanwhile, the stirring of the third stirring paddle 203c-3 causes the scraper 305c-5 to rotate continuously via the telescopic rod 203c-4, scraping the conical surface of the inner surface of the discharge pipe 101 to prevent material from getting stuck and accumulating at the top. Also, because the telescopic rod 203c-4 is provided, it prevents the third stirring paddle 203c-3 from getting stuck when it rises and falls.

[0041] The remaining structure is the same as that in Example 1. Example

[0042] Reference Figures 2-5 This is the third embodiment of the present invention, which differs from the second embodiment in that the adjustment component 303 is used in a different way.

[0043] Compared to Embodiment 2, the adjustment component 303 further includes a handwheel 303a connected to the fixed block 105. One end of the handwheel 303a extending into the fixed block 105 is penetrated by a second guide rod 303b. One end of the second guide rod 303b extending into the inner surface of the discharge tube 101 is connected to a connecting rod 303c. The connecting rod 303c is connected to the outer surface of the second barrier 302 to control the rotation of the second barrier 302.

[0044] During use, the handwheel 303a and the fixed block 105 form a rotating structure, and the handwheel 303a and the second guide rod 303b are threadedly connected. The outer end of the second guide rod 303b is provided with a limit rod 303b-1, which can be limited to reciprocating sliding in the material discharge tube 101 through the limit rod 303b-1.

[0045] When the handwheel 303a is rotated, the handwheel 303a can be limited to rotate and engage with the second guide rod 303b. Since the second guide rod 303b is limited by the limiting rod 303b-1 and cannot rotate, the second guide rod 303b can only translate. Thus, the second guide rod 303b can drive one end of the connecting rod 303c to move through its own movement. Since the length of the connecting rod 303c remains unchanged, the other end of the connecting rod 303c can pull or push the second blocking member 302, thereby realizing the flipping of the second blocking member 302.

[0046] By flipping the second barrier 302, the angle and gap between the second barrier 302 and the first barrier 301 can be adjusted. This angle and gap can be used to adjust the drop point of the material entering the bucket elevator slag hopper at any time. The drop pipe between the buffer bucket and the bucket elevator box is vertically and straight. While ensuring the original cross-section of the drop pipe, the direction of the waste slag entering the bucket elevator box after boiler combustion is adjusted so that the waste slag enters the bucket along the center line of the bucket elevator hopper. This ensures that the bucket elevator chain, head shaft, and bearings are evenly stressed and experience uniform wear within the allowable range. At the same time, wear-resistant and high-temperature resistant plates are used to make the bucket elevator drop pipe to enhance its wear resistance.

[0047] The remaining structure is the same as that in Example 2.

[0048] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape, and proportions of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of the invention.
