Description

Technical Field

[0001] This invention relates to the field of conveying equipment, specifically a chain-type bucket conveyor structure. Background Technology

[0002] Chain bucket conveyors are continuous conveying equipment that uses a traction chain to drive a series of interconnected buckets for material transport. They are widely used in the slag removal systems of circulating fluidized bed boilers, pulverized coal boilers, and waste incinerators. In these applications, the bucket conveyors need to directly receive and transport high-temperature waste residue with temperatures typically between 200℃ and 800℃, strong abrasiveness, and a wide particle size distribution. This type of waste residue often contains unburned carbon particles, molten agglomerates, and sharp-edged particles, which places stringent requirements on the high-temperature resistance, wear resistance, and operational reliability of the conveying equipment.

[0003] In the existing chain bucket conveyor structure, the buckets circulate along the guide rail with the traction chain. At the feeding end, they receive high-temperature waste residue and convey it forward. At the unloading end, the buckets are unloaded by the sprocket and return empty. This achieves continuous conveying. During the conveying process, the buckets are directly subjected to the contact heat transfer of high-temperature materials, the impact of falling materials, and sliding wear. The service conditions are harsh. As the operating time increases, the accumulation of damage caused by thermal fatigue and wear on the buckets is inevitable, and they need to be replaced as a whole periodically.

[0004] However, in long-term practical engineering applications, the existing chain bucket conveyor structure has revealed the following obvious shortcomings: First, traditional buckets are usually fixed to the chain accessories by welding or riveting, which is complicated in terms of disassembly and assembly, and the downtime for maintenance during replacement is long, labor-intensive, and costly, which seriously restricts the economic efficiency and maintenance efficiency of the equipment.

[0005] Secondly, the traditional scale bucket structure is simple and the air-cooling effect is not high. Moreover, the high-temperature waste residue is densely packed inside the bucket due to gravity. The heat can only be slowly dissipated through natural convection and radiation of the bucket wall, which makes it difficult to form effective forced convection heat dissipation. As a result, the scale bucket is in the high-temperature working range for a long time. The continuous heat accumulation effect not only aggravates the strength decay and creep tendency of the scale bucket material at high temperature, but also induces weld cracking or deformation due to thermal stress concentration, further accelerating the degradation process of scale bucket performance and shortening the overall service life of the equipment.

[0006] In summary, the existing chain bucket conveyor structure has obvious deficiencies in terms of quick-release maintenance of the buckets and heat dissipation and cooling capabilities. Structural optimization and improvement are urgently needed to enhance the ease of maintenance and service life of the equipment under high-temperature and heavy-load conditions. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a chain-type bucket conveying structure, including a chain conveying assembly, a number of buckets are fixedly connected at equal intervals on the chain conveying assembly, the buckets move in a cycle and continuously convey high-temperature waste residue to the upper left, the buckets are provided with thin plate buckets that can be quickly disassembled, and the thin plate buckets and the buckets are together provided with a separating mechanism for separating waste residue.

[0008] The thin plate hopper is equipped with a ventilation component for cooling the thin plate hopper that is conveying high-temperature waste residue. The ventilation component cools the thin plate hopper by increasing the bottom area of ​​the thin plate hopper and guiding external airflow through the bottom of the thin plate hopper.

[0009] The separating mechanism includes several steel bars that are interspersed inside the scale bucket and the thin plate bucket. The steel bars are divided into upper and lower groups, with the spacing between the upper group of steel bars being larger than that between the lower group of steel bars, thereby separating waste slag blocks of various diameters in the vertical direction.

[0010] High-temperature waste slag conveying operations are carried out by utilizing the quick-release installation of thin plate hoppers, the ventilation and cooling of thin plate hoppers, and the separation of waste slag blocks.

[0011] Preferably, the ventilation assembly includes several heat dissipation fins fixedly installed at the bottom of the thin plate hopper, with the heat dissipation fins arranged at equal intervals on the left and right sides.

[0012] Preferably, there is a gap between the bottom of the heat dissipation fins and the sump, and the heat dissipation fins are placed in the front-to-back direction so that the airflow carries away the heat in the sump when it flows along the heat dissipation fins.

[0013] Preferably, the upper part of the thin plate bucket is open, and the thin plate bucket gradually narrows from top to bottom, and the upper opening of the thin plate bucket matches the upper part of the scale bucket, so that when the thin plate bucket is put into the scale bucket, it is stuck in the upper part of the scale bucket.

[0014] Preferably, the bottom of the thin plate hopper has a wave structure, which separates and limits the waste slag accumulated on it.

[0015] Preferably, the thin plate bucket has an inclined plate structure on the front and rear sides, with the inclined plate structure on the front side extending out of the front side of the bucket and the inclined plate structure on the rear side extending out of the rear side of the bucket, so that the airflow is guided into the bottom of the thin plate bucket through the inclined plate structure.

[0016] Preferably, fixing blocks are fixedly installed on the left and right sides of the thin plate bucket, the fixing blocks are located at the front of the thin plate bucket, and a frame for embedding the fixing blocks is provided on the inner side of the bucket.

[0017] Preferably, the reinforcing bar has a stepped shaft structure, with one end of the reinforcing bar having a hexagonal truncated pyramid structure and the other end having a threaded structure.

[0018] Preferably, the upper set of reinforcing bars is inserted into the scale bucket and the thin plate bucket from front to back, and the lower set of reinforcing bars is inserted into the scale bucket and the thin plate bucket from back to front, so that the reinforcing bars are threaded onto the scale bucket.

[0019] Preferably, the upper set of steel bars is positioned at the front of the thin plate hopper by abutting and limiting, and the lower set of steel bars is positioned at the rear of the thin plate hopper by abutting and limiting, with the steel bars located in the right position in the thin plate hopper.

[0020] The beneficial effects of this invention are as follows: First, this invention uses a thin-plate bucket that can be quickly disassembled and installed inside the scale bucket to carry and transport high-temperature waste residue. When replacing it, there is no need to cut the entire scale bucket off the chain conveyor assembly; only the lower-cost thin-plate bucket needs to be quickly replaced, significantly shortening downtime and greatly reducing replacement costs. At the same time, the ventilation components set on the thin-plate bucket expand the bottom heat dissipation area and guide external airflow, achieving efficient air cooling of the thin-plate bucket. Several steel bars are used to separate waste residue blocks of different diameters into layers, making full use of the internal height space of the thin-plate bucket, alleviating the dense accumulation of high-temperature waste residue, accelerating the dissipation of heat inside the waste residue, thereby effectively ensuring the service life of the thin-plate bucket under high-temperature conditions and reducing the frequency of equipment downtime and replacement.

[0021] II. This invention employs two sets of stepped steel bars, one above the other, interlocking with each other in the scale bucket and the thin plate bucket. On one hand, the stepped structure at the ends of the steel bars limits and fixes the front and rear positions of the thin plate bucket, enabling rapid, weld-free installation and disassembly. On the other hand, because the spacing between the upper set of steel bars is greater than that between the lower set, large pieces of waste falling into the bucket are supported and suspended by the upper set of steel bars, while smaller pieces of waste fall through the gaps in the upper set into the lower set for further separation. This effectively achieves graded arrangement of waste in the vertical direction. This structure, by suspending some of the waste, reduces the direct contact area between the waste and the bottom of the thin plate bucket and the pressure of dense accumulation, alleviating the continuous heat conduction caused by waste accumulation on the thin plate bucket and extending its service life.

[0022] Third, this invention employs several heat dissipation fins fixedly installed at the bottom of the thin plate bucket, increasing the heat dissipation surface area at the bottom of the thin plate bucket. Compared with the natural heat dissipation method of the traditional scale bucket bottom being simply exposed to the air, it can effectively suppress the temperature rise of the thin plate bucket during the transportation process. In addition, with the help of the inclined plate structure set on the front and rear sides of the thin plate bucket, the external ambient airflow can be effectively guided through the bottom of the thin plate bucket, so that the cooling airflow flows directionally along the gaps of the heat dissipation fins, thereby carrying away the heat accumulated at the bottom of the thin plate bucket and further improving the cooling effect.

[0023] Fourth, the present invention adopts a thin plate bucket with a wave-shaped bottom. The wave-shaped surface forms multiple transverse partitions and friction limits for the waste slag accumulated inside. During the inclined conveying process of the scale bucket with the chain conveyor assembly, the wave structure can effectively suppress the large-scale sliding of the waste slag in the thin plate bucket, prevent the waste slag from causing excessive friction wear on the inner wall of the thin plate bucket due to sliding, and improve the wear resistance and service life of the thin plate bucket.

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0033] See Figure 1 and Figure 2 A chain-type bucket conveying structure includes a chain conveying assembly 1, on which several buckets 2 are fixedly connected at equal intervals. The buckets 2 move in a cycle and continuously convey high-temperature waste residue to the upper left. A thin plate bucket 3 that can be quickly disassembled is provided on the buckets 2. The thin plate bucket 3 and the buckets 2 are together provided with a separating mechanism 4 for separating waste residue.

[0034] The chain conveyor assembly 1 in this embodiment adopts the power structure of existing conventional conveying equipment, which can circulate the scale bucket 2, and will not be described in detail here.

[0035] When conveying high-temperature waste residue, the chain conveyor assembly 1 drives several scale buckets 2 to rotate in a cycle. The scale buckets 2 drive the thin plate buckets 3 to move synchronously, so that the thin plate buckets 3 passing through the unloading point are discharged into the high-temperature waste residue by the unloading equipment. The continuously conveying thin plate buckets 3 continuously carry the high-temperature waste residue to the unloading point. When the thin plate buckets 3 reach the unloading point, the chain conveyor assembly 1 drives the thin plate buckets 3 to flip through the scale buckets 2, so that the high-temperature waste residue in the thin plate buckets 3 is discharged under the action of gravity. Then, the empty thin plate buckets 3 return to the feeding end along the return section. This cycle is repeated to realize continuous conveying operation.

[0036] During the process of conveying high-temperature waste residue in the thin plate hopper 3, the high-temperature waste residue on the thin plate hopper 3 can be separated and arranged by the separation mechanism 4, so that some of the large-diameter high-temperature waste residue is suspended, thereby reducing the direct contact area and dense accumulation pressure between the waste residue and the bottom of the thin plate hopper 3, alleviating the continuous heat conduction caused by the accumulation of waste residue on the thin plate hopper 3, and extending the service life of the thin plate hopper 3.

[0037] Since the thin plate bucket 3 is placed inside the scale bucket 2 in a quick and easy way, when replacing the thin plate bucket 3, it is not necessary to cut the entire scale bucket 2 off the chain transmission assembly 1. Only the lower-cost thin plate bucket 3 needs to be quickly replaced, which significantly shortens the downtime for maintenance and greatly reduces the replacement cost.

[0038] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The thin plate hopper 3 is equipped with a ventilation component 31 for cooling the thin plate hopper 3 that is conveying high-temperature waste residue. When the thin plate hopper 3 is conveying high-temperature waste residue, the ventilation component 31 cools the thin plate hopper 3 by expanding the bottom area of ​​the thin plate hopper 3 and guiding the external airflow through the bottom of the thin plate hopper 3. Compared with the natural heat dissipation method of the traditional scale hopper 2 where the bottom is simply exposed to the air, it can effectively suppress the temperature rise of the thin plate hopper 3 during the conveying process.

[0039] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The separating mechanism 4 includes several steel bars 41 that are interspersed inside the scale bucket 2 and the thin plate bucket 3. The steel bars 41 are divided into upper and lower groups. The spacing between the upper group of steel bars 41 is larger than that between the lower group of steel bars 41, thereby separating waste slag blocks of various diameters in the vertical direction.

[0040] When high-temperature waste slag is fed into the thin plate hopper 3, the spacing of the upper group of reinforcing bars 41 is larger than that of the lower group of reinforcing bars 41. This allows large pieces of waste slag falling into the thin plate hopper 3 to be supported and suspended by the upper group of reinforcing bars 41, while smaller pieces of waste slag pass through the gaps in the upper group and fall into the lower group for further separation. This effectively achieves the graded arrangement of waste slag in the vertical direction, reduces the direct contact area between the waste slag and the bottom of the thin plate hopper 3 and the pressure of dense accumulation, alleviates the continuous heat conduction caused by the accumulation of waste slag on the thin plate hopper 3, and extends the service life of the thin plate hopper 3.

[0041] To facilitate the installation and connection of the thin plate bucket 3 inside the scale bucket 2, the present invention designs the following structure: (See reference) Figure 3 and Figure 4 The upper part of the thin plate bucket 3 is open, and the thin plate bucket 3 gradually narrows from top to bottom. The upper opening of the thin plate bucket 3 matches the upper part of the scale bucket 2, so that when installing the thin plate bucket 3, the operator only needs to put the thin plate bucket 3 into the scale bucket 2, and the thin plate bucket 3 will be stuck in the upper part of the scale bucket 2 under the action of gravity.

[0042] See Figure 3 , Figure 4 and Figure 5 The thin plate bucket 3 has fixed blocks 32 on both sides. The fixed blocks 32 are located at the front of the thin plate bucket 3. The inner side of the scale bucket 2 is provided with a frame 33 for embedding the fixed blocks 32. When the thin plate bucket 3 is snapped into the scale bucket 2, the fixed blocks 32 are located in front of the frame 33. Then, the thin plate bucket 3 is pushed backward, so that the thin plate bucket 3 drives the fixed blocks 32 to be embedded into the frame 33, thereby making the thin plate bucket 3 and the scale bucket 2 simply connected together.

[0043] See Figure 3 , Figure 4 , Figure 5 and Figure 6 The reinforcing bar 41 has a stepped shaft structure, with one end of the reinforcing bar 41 having a hexagonal truncated pyramid structure and the other end having a threaded structure. The upper set of reinforcing bars 41 passes through the scale hopper 2 and the thin plate hopper 3 from front to back, and the lower set of reinforcing bars 41 passes through the scale hopper 2 and the thin plate hopper 3 from back to front, so that the reinforcing bars 41 are threadedly connected to the scale hopper 2. The upper set of reinforcing bars 41 is abutted and limited on the front side of the thin plate hopper 3, and the lower set of reinforcing bars 41 is abutted and limited on the rear side of the thin plate hopper 3. The reinforcing bars 41 are located in the right position in the thin plate hopper 3.

[0044] Subsequently, a set of upper steel bars 41 are inserted from front to back through the scale bucket 2 and the thin plate bucket 3. Then, the set of steel bars 41 are rotated so that the steel bars 41 are threaded onto the rear side plate of the scale bucket 2, and the stepped structure of the set of steel bars 41 abuts against the front side of the thin plate bucket 3, thereby limiting the front side of the thin plate bucket 3. Then, a set of lower steel bars 41 are inserted from back to front through the scale bucket 2 and the thin plate bucket 3, on the same principle, thereby limiting and fixing the front and rear positions of the thin plate bucket 3, realizing the rapid installation of the thin plate bucket 3 without welding.

[0045] When the high-temperature waste falls into the thin plate hopper 3, large pieces of waste are supported and suspended by the upper group of steel bars 41, while small pieces of waste pass through the gaps in the upper group and fall into the lower group for further separation. Even smaller pieces of high-temperature waste pass through the lower group of steel bars 41 again and fall into the thin plate hopper 3. This effectively achieves the graded arrangement of waste in the vertical direction. By suspending part of the waste, this structure reduces the direct contact area between the waste and the bottom of the thin plate hopper 3 and the pressure of dense accumulation, which alleviates the continuous heat conduction caused by the accumulation of waste on the thin plate hopper 3 and extends the service life of the thin plate hopper 3.

[0046] It should be noted that in actual working conditions, the high-temperature waste slag falls into the thin plate hopper 3 in a disordered accumulation state, and the particle size distribution of the waste slag is extremely uneven and often accompanied by melting and adhesion. The upper set of steel bars 41 can only support and suspend some of the larger blocky waste slag, and cannot perform precise particle size screening or grading of the waste slag. The waste slag falling into the lower set of steel bars 41 and the bottom of the thin plate hopper 3 is still a mixture of particles of different sizes. The core function of the steel bars 41 is to increase the porosity of the waste slag accumulation by suspending large pieces of material, reduce the dense contact area between the waste slag and the bottom of the thin plate hopper 3, thereby alleviating the local heating pressure caused by direct heat transfer at the bottom of the thin plate hopper 3, rather than performing strict screening, separation or particle size classification of the high-temperature waste slag.

[0047] When the thin plate hopper 3 moves to the unloading point for tipping and unloading, the high-temperature waste residue inside the thin plate hopper 3 first slides down to the left side of the thin plate hopper 3 under the action of gravity. As the thin plate hopper 3 is further tipped, the high-temperature waste residue slides down along the left side of the thin plate hopper 3. Since the steel bar 41 in this invention is located on the right side of the thin plate hopper 3, the steel bar 41 will not obstruct the unloading of the high-temperature waste residue.

[0048] To improve the heat dissipation effect of the thin plate hopper 3 when conveying high-temperature waste residue and to prevent the temperature of the thin plate hopper 3 from becoming too high, which would reduce its lifespan, the present invention designs the following structure: (See attached diagram) Figure 3 , Figure 4 and Figure 5The ventilation component 31 includes several heat dissipation fins 311 fixedly installed at the bottom of the thin plate bucket 3. The heat dissipation fins 311 are arranged at equal intervals on the left and right sides. The heat dissipation fins 311 increase the heat dissipation surface area at the bottom of the thin plate bucket 3. Compared with the natural heat dissipation method of the bottom of the traditional scale bucket 2 being simply exposed to the air, it can effectively suppress the temperature rise of the thin plate bucket 3 during the conveying process.

[0049] To further improve the heat dissipation effect of the thin-plate hopper 3 when conveying high-temperature waste residue, the present invention designs the following structure: (See reference) Figure 3 , Figure 4 , Figure 5 and Figure 6 The thin plate bucket 3 has an inclined plate structure on the front and rear sides, with the inclined plate structure on the front side extending out of the front side of the scale bucket 2 and the inclined plate structure on the rear side extending out of the rear side of the scale bucket 2. When the thin plate bucket 3 is transporting high-temperature waste residue, the airflow from the external environment can be guided into the bottom of the thin plate bucket 3 through the inclined plate structure. There is a gap between the bottom of the heat dissipation fin 311 and the scale bucket 2. The heat dissipation fin 311 is placed in the front-rear direction, so that the airflow can efficiently remove the heat in the thin plate bucket 3 when it flows along the heat dissipation fin 311.

[0050] It should be noted that the inclined plate structure set on the front and rear sides of the thin plate bucket 3 in this invention is only a passive airflow guiding component. Its working principle relies on the airflow flowing back and forth in the external environment being guided to the bottom area of ​​the thin plate bucket 3 through the inclined plate structure. Compared with the natural convection heat dissipation method where the bottom of the traditional scale bucket 2 is completely open and exposed to static air, it increases the chance of airflow contacting the heat dissipation fins 311, thereby relatively improving the heat dissipation efficiency. However, this structure does not have any active air supply device and does not have the function of forced suction or pressurized air intake. It cannot actively transport the external airflow to the bottom of the thin plate bucket 3. Therefore, the inclined plate structure is only a passive optimization of the traditional natural heat dissipation state, rather than an active forced air cooling method.

[0051] To prevent high-temperature waste residue from sliding within the thin-plate hopper 3 during transport, which would cause rapid wear and tear on the hopper 3 and reduce its service life, this invention designs the following structure: (See attached diagram) Figure 4 and Figure 5 The bottom of the thin plate bucket 3 has a wave structure, which separates and limits the waste slag accumulated on it.

[0052] When conveying high-temperature waste residue, the corrugated surface of the thin plate bucket 3 forms multiple transverse separations and friction limits for the waste residue accumulated inside it. During the inclined conveying process of the scale bucket 2 with the chain conveyor assembly 1, the corrugated structure can effectively suppress the large-scale sliding of the waste residue in the thin plate bucket 3, prevent the waste residue from causing excessive friction wear on the inner wall of the thin plate bucket 3 due to sliding, and improve the wear resistance and service life of the thin plate bucket 3.

[0053] Although this invention adds a replaceable thin-plate bucket 3, several heat dissipation fins 311, and two sets of upper and lower reinforcing bars 41 to the traditional conveying structure, which slightly increases the initial cost, the quick disassembly and assembly design of the thin-plate bucket 3 significantly shortens downtime for maintenance and reduces the cost of replacement parts per transaction. The suspended separation of large pieces of waste residue by the reinforcing bars 41 reduces the dense contact area between the waste residue and the bottom of the thin-plate bucket 3 and the continuous heat conduction, effectively extending the service life and replacement cycle of the thin-plate bucket 3. In addition, the passive heat dissipation optimization of the ventilation component 31 further slows down the high-temperature degradation rate of the material of the thin-plate bucket 3.

[0054] The combined effects of the above technologies reduce the frequency of maintenance, spare parts consumption, and downtime losses throughout the equipment's life cycle, and can quickly balance and offset the limited cost investment in the early stage, thereby achieving significant economic benefits in long-term operation. In addition, the thin plate hopper 3 and the steel bar 41, which are in direct contact with high-temperature waste residue, are all made of wear-resistant and high-temperature resistant materials to fully ensure their reliability under harsh working conditions.
