Description

Technical Field

[0001] This invention relates to the field of chain conveyor equipment, and in particular to a chain conveyor equipment used in the pretreatment stage of industrial solid waste. Background Technology

[0002] In the pretreatment of industrial solid waste, solid waste materials are usually characterized by complex composition (containing lumps, granules, dust, and a small amount of attached liquid), large differences in physical properties (high hardness, uneven moisture content), and flexible conveying path requirements. Traditional chain plate conveying equipment has the following problems in practical applications: Traditional chain plates have a flat or simple groove structure on their surface. Dust in solid waste is easy to accumulate in the gaps of the chain plate, and attached liquids (such as residual washing water after solid waste pretreatment) are easy to remain on the surface of the chain plate. Long-term use will lead to chain plate corrosion, jamming, and even contamination of solid waste materials to be processed later. Traditional chain plates and supporting structures are mostly fixed by welding or bolts. When the supporting components need to be replaced due to wear or corrosion, a large number of bolts need to be disassembled or welded points need to be cut. The operation is cumbersome and time-consuming, resulting in long downtime for equipment maintenance and affecting the continuous operation of the pre-processing production line. For irregularly shaped solid waste, traditional flat chain conveyors lack effective limiting structures. During the conveying process, they are prone to slippage due to equipment vibration or turning (if forced to turn), which not only causes material loss, but may also lead to equipment blockage or safety accidents. Summary of the Invention

[0003] Based on this, it is necessary to provide a chain plate conveyor for use in the pretreatment stage of industrial solid waste, which addresses the above-mentioned technical problems. The chain plate body and the support component adopt a slotted connection structure, eliminating the need for bolts or welding fixation. The support component can be quickly disassembled and assembled during maintenance, avoiding the cumbersome operation of traditional fixed structures and improving equipment maintenance efficiency.

[0004] This invention provides a chain conveyor device for use in the pretreatment stage of industrial solid waste, comprising a basic conveying section and a path turning section connected end to end, wherein both the basic conveying section and the path turning section include multiple chain plate bodies and supporting components; The two ends of the chain plate body are respectively connected to the pins of the chain through two connecting shafts. The side of the chain plate away from the chain forms a concave groove. The support member is used to be engaged in the groove. The surface of the support member is concave, and a through hole is opened in the concave part.

[0005] In one embodiment, the chain plate body includes a connector, a positioning frame, and a positioning tube; the positioning frame is disposed between two connectors, the middle part of the positioning frame is configured as a through opening, the positioning tube is fixed to the bottom end of the connector, and one end of the connecting shaft is fixedly installed inside the positioning tube.

[0006] In one embodiment, the support member includes a snap-fit ​​connector and a support plate; the support plate is disposed between two snap-fit ​​connectors, the upper surface of the support plate is configured as an arc-shaped concave portion in the middle, the lower surface of the arc-shaped concave portion is located within the through opening, and the arc-shaped concave portion has multiple through holes.

[0007] In one embodiment, the two snap-fit ​​connectors are respectively snapped into the two connectors. A support member is installed on the side of the connector away from the snap-fit ​​connector. When the snap-fit ​​connector is snapped into the connector, the connector is bent away from the snap-fit ​​connector under force. After the snap-fit ​​connector is snapped into the connector, the connector returns to its original position under the support of the support member.

[0008] In one embodiment, the connector includes a first end plate, a second end plate, and a first bent plate; one side of the first end plate is connected to the positioning frame, the positioning tube is fixed to the bottom of the first end plate, the first end plate is located directly below the second end plate, the first bent plate is located on the side of the first end plate connected to the fixing frame, the first end plate and the second end plate are connected by the first bent plate, and the first bent plate is elastic.

[0009] In one embodiment, a mounting cavity is formed between the first end plate, the second end plate, and the first bent plate, and the support member is installed in the mounting cavity.

[0010] In one embodiment, a first slot is provided on the side of the first end plate facing the second end plate, and a second slot is provided on the side of the second end plate facing the first end plate. The support member includes a rod and a spring. The two ends of the spring are respectively connected to the two rods, the central axes of the two rods coincide, and the two rods are respectively inserted into the first slot and the second slot.

[0011] In one embodiment, the snap-fit ​​connector includes a third end plate and a second bent plate; the two third end plates are directly opposite each other, with one side of the lower third end plate connected to the support plate, and the second bent plate is located on the side of the third end plate connected to the support plate. The two third end plates are connected by the second bent plate, and the inner surface of the second bent plate is used to fit against the outer surface of the first bent plate.

[0012] In one embodiment, a cover plate is provided at the connection between the lower third end plate and the support plate, the lower surface of the cover plate is used to fit against the outer surface of the positioning tube, and a flat plate is connected to the top of the upper third end plate, the flat plate being located directly above the second end plate.

[0013] In one embodiment, a first inclined surface and a second inclined surface are respectively provided at the corners directly opposite the first end plate and the flat plate.

[0014] The aforementioned chain conveyor system, used in the pretreatment stage of industrial solid waste, first installs multiple chain plates one by one onto the chain pins via connecting shafts on both sides. Then, the support components are aligned with the concave grooves on the side of the chain plate away from the chain, and vertical pressure is applied to engage the support components, completing the assembly of a single chain plate unit. This process continues until all chain plate bodies are equipped with support components. The conveyor system is then started, and the chain, driven by the drive unit, circulates, synchronously moving the chain plate bodies and the engaged support components along a preset path. Industrial solid waste (such as construction waste blocks, smelting slag, etc.) is evenly fed onto the support components in the basic conveying section via a feeding device (such as a hopper or conveyor belt). Because the surface of the support components is concave, it provides circumferential restraint on the material, preventing material from being affected by equipment vibration. Slight tilting may cause slippage; if the solid waste contains dust (such as fly ash) or attached liquid (such as residual water in wet coal slag), it will naturally fall through the through holes in the recessed part of the support during the conveying process and fall into the dust or liquid collection device (such as receiving hopper or scraper conveyor) set below the equipment to prevent dust from escaping or liquid from stagnating and corroding the chain plate; after the equipment has been running for a certain period of time (such as wear of the support or blockage of the through holes), after stopping the machine, an upward pulling force can be applied directly to the support to make the support disengage from the slot of the chain plate body for separate cleaning (such as unblocking the through holes and wiping off residual materials) or replacement; if the chain plate body needs maintenance, the damaged chain plate body can be removed separately by disassembling the mating structure of the connecting shaft and the chain pin, without disassembling the entire conveying section, which greatly shortens the maintenance time. The chain plate body and the support component adopt a slotted connection structure, eliminating the need for bolts or welding fixation. The support component can be quickly disassembled and assembled during maintenance, avoiding the cumbersome operation of traditional fixed structures and improving equipment maintenance efficiency. The concave structure of the support component enables material limiting, adapting to irregular block solid waste and preventing slippage during conveying. The through-hole design allows for real-time discharge of dust and liquids, preventing chain plate corrosion and jamming caused by material accumulation, extending equipment service life, and reducing dust pollution to the workshop environment.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The following is combined with Figures 1 to 8 This invention describes a chain conveyor system used in the pretreatment stage of industrial solid waste.

[0020] like Figures 1 to 3As shown, in one embodiment, a chain conveyor device used in the pretreatment stage of industrial solid waste includes a basic conveying section 10 and a path turning section 20 connected end to end. Both the basic conveying section 10 and the path turning section 20 include multiple chain plate bodies 100 and support members 200. The two ends of the chain plate body 100 are respectively connected to the pins of the chain through two connecting shafts 30. The side of the chain plate away from the chain forms a concave groove. The support member 200 is used to engage in the groove. The surface of the support member 200 is concave, and a through hole 222 is provided in the concave part.

[0021] The aforementioned chain conveyor used in the pretreatment stage of industrial solid waste first installs multiple chain plate bodies 100 one by one onto the chain pins via connecting shafts 30 on both sides. Then, the support member 200 is aligned with the concave groove on the side of the chain plate body 100 away from the chain, and vertical pressure is applied to make the support member 200 snap into the groove, completing the assembly of a single chain plate unit until all chain plate bodies 100 are equipped with the support member 200. The conveyor is then started, and the chain circulates under the drive of the drive device, synchronously moving the chain plate bodies 100 and the snapped support members 200 along a preset path. Industrial solid waste (such as construction waste blocks, smelting slag, etc.) is evenly fed onto the support member 200 of the basic conveying section 10 through a feeding device (such as a hopper or conveyor belt). Because the surface of the support member 200 has a concave structure, it can form a circumferential limit on the material, preventing the material from being affected by equipment vibration. Slippage may occur due to movement or slight tilting; if the solid waste contains dust (such as fly ash) or attached liquid (such as residual water in wet coal slag), it will naturally fall through the through hole 222 in the recess of the support 200 during the conveying process and fall into the dust or liquid collection device (such as receiving hopper or scraper conveyor) set below the equipment to prevent dust from escaping or liquid from stagnating and corroding the chain plate; after the equipment has been running for a certain period of time (such as wear of the support 200 or blockage of the through hole 222), an upward pulling force can be directly applied to the support 200 after the machine is stopped, so that the support 200 can be disengaged from the slot of the chain plate body 100 for separate cleaning (such as unblocking the through hole 222 and wiping off residual materials) or replacement; if the chain plate body 100 needs maintenance, the damaged chain plate body 100 can be removed separately by disassembling the mating structure between the connecting shaft 30 and the chain pin shaft, without disassembling the entire conveying section, which greatly shortens the maintenance time. The chain plate body 100 and the support component 200 adopt a slot-and-click structure, eliminating the need for bolts or welding fixation. During maintenance, the support component 200 can be quickly disassembled and assembled, avoiding the cumbersome operation of traditional fixed structures and improving equipment maintenance efficiency. The concave structure of the support component 200 enables material limiting, adapting to irregular blocky solid waste and preventing slippage during conveying. The through hole 222 design allows for real-time discharge of dust and liquids, preventing chain plate corrosion and jamming caused by material accumulation, extending equipment service life, and reducing dust emission pollution to the workshop environment.

[0022] like Figure 4As shown, in one embodiment, the chain plate body 100 includes a connector 110, a positioning frame 120 and a positioning tube 130; the positioning frame 120 is disposed between two connectors 110, the middle part of the positioning frame 120 is configured as a through opening 121, the positioning tube 130 is fixed to the bottom end of the connector 110, and one end of the connecting shaft 30 is fixedly installed in the positioning tube 130.

[0023] Specifically, the positioning tube 130 provides a precise installation reference for the connecting shaft 30, ensuring uniform clearance between the connecting shaft 30 and the chain pin, preventing jamming or chain wear caused by the shaking of the connecting shaft 30 during chain plate body 100 operation, and adapting to the heavy-duty conveying requirements of industrial solid waste; the through-hole 121 in the middle of the positioning frame 120 reduces the overall weight of the chain plate body 100 and the chain drive load, and provides space for the lower surface of the subsequent support 200, ensuring that the support 200 forms a compact structure with the chain plate body 100 after installation, avoiding interference with other components during conveying; the connector 110 provides a dedicated mating structure for the snap-fit ​​of the support 200, avoiding the design defects of traditional chain plates with a one-cut design, and improving the fitting accuracy between the chain plate body 100 and the support 200.

[0024] like Figure 5 As shown, in one embodiment, the support member 200 includes a snap-fit ​​connector 210 and a support plate 220; the support plate 220 is disposed between two snap-fit ​​connectors 210, the upper surface of the support plate 220 is configured with an arc-shaped concave 221 in the middle, the lower surface of the arc-shaped concave 221 is located in the through opening 121, and a plurality of through holes 222 are opened on the surface of the arc-shaped concave 221.

[0025] Specifically, the arc-shaped concave structure 221 of the support plate 220, compared to ordinary flat or right-angle concave structures, better conforms to the shape of blocky and granular solid waste (such as the irregular curved surface of construction waste blocks), with a larger contact area, further enhancing the material limiting effect. Even with high equipment vibration frequencies, it can effectively prevent material displacement or slippage. The design of multiple through holes 222 increases the discharge area of ​​dust and liquids, improving the discharge efficiency for wet solid waste (such as sludge cake) or high-dust solid waste (such as slag powder), reducing material residue on the surface of the support plate 220, and reducing the difficulty of subsequent cleaning. The corresponding design of the snap-fit ​​connector 210 and the connector 110 ensures that the support component 200 is accurately positioned when it snaps into the chain plate body 100, avoiding conveying imbalance caused by the offset of the support component 200, and extending the service life of the chain and chain plate.

[0026] like Figure 8As shown, in one embodiment, two snap-fit ​​connectors 210 are snapped into two connectors 110 respectively. A support member 300 is installed on the side of the connector 110 away from the snap-fit ​​connector 210. When the snap-fit ​​connector 210 snaps into the connector 110, the connector 110 is bent away from the snap-fit ​​connector 210 by force. After the snap-fit ​​connector 210 snaps into the connector 110, the connector 110 returns to its original position under the support of the support member 300.

[0027] Specifically, when the snap-fit ​​connector 210 is snapped in, the connector head 110 can be bent under force, reducing the force required during assembly (no need to use tools to strike), allowing a single worker to complete the installation of the support component 200, thus improving assembly efficiency; after snapping in, the support component 300 drives the connector head 110 to reset, ensuring that the connector head 110 and the snap-fit ​​connector 210 fit tightly together, preventing the support component 200 from loosening and falling off due to vibration during transportation; the elastic buffer of the support component 300 can absorb the impact force during snapping, preventing edge wear caused by hard contact between the connector head 110 and the snap-fit ​​connector 210, and extending the service life of the snap-fit ​​structure.

[0028] like Figure 6 and Figure 7 As shown, in one embodiment, the connector 110 includes a first end plate 111, a second end plate 112, and a first bent plate 113; one side of the first end plate 111 is connected to the positioning frame 120, the positioning tube 130 is fixed to the bottom of the first end plate 111, the first end plate 111 is located directly below the second end plate 112, the first bent plate 113 is located on the side of the first end plate 111 connected to the fixing frame, the first end plate 111 and the second end plate 112 are connected by the first bent plate 113, and the first bent plate 113 is elastic.

[0029] Specifically, the elastic first bending plate 113 provides controllable deformation capability for the connector 110, which can meet the bending requirements when the snap-fit ​​connector 210 is snapped in, and can also reduce the dependence on the support 300 through its own elasticity to reduce the loosening of the snap-fit ​​due to the failure of the support 300. The vertically aligned layout of the first end plate 111 and the second end plate 112 forms a symmetrical snap-fit ​​space, so that the force of the snap-fit ​​connector 210 after it is snapped in is distributed to the two end plates, avoiding deformation of the connector 110 due to excessive local stress (such as warping of the second end plate 112). The first end plate 111 also connects the positioning frame 120 and the positioning tube 130, reducing the number of connection nodes of the chain plate body 100, reducing the risk of processing errors, and improving assembly accuracy.

[0030] In one embodiment, a mounting cavity 114 is formed between the first end plate 111, the second end plate 112, and the first bent plate 113, and the support member 300 is installed in the mounting cavity 114.

[0031] Specifically, the mounting cavity 114 provides a semi-enclosed installation environment for the support component 300, which can effectively prevent dust and debris in industrial solid waste from entering the interior of the support component 300, avoid the support component 300 from losing its elasticity due to impurities, and ensure the long-term effective operation of the support component 300; the mounting cavity 114 integrates the support component 300 with the connector 110, without external protruding structures, to prevent materials (such as long strips of solid waste) from snagging on the support component 300 during the conveying process, and prevent equipment blockage or material damage; the mounting cavity 114 is embedded inside the connector 110, without occupying additional space in the conveying path, ensuring that the overall structure of the equipment is compact and adaptable to the needs of narrow workshop layouts.

[0032] In one embodiment, the first end plate 111 has a first slot 1111 on the side facing the second end plate 112, and the second end plate 112 has a second slot 1121 on the side facing the first end plate 111. The support member 300 includes a rod 310 and a spring 320. The two ends of the spring 320 are respectively connected to the two rods 310, the central axes of the two rods 310 coincide, and the two rods 310 are respectively inserted into the first slot 1111 and the second slot 1121.

[0033] Specifically, the insertion of the rod 310 into the slot provides axial guidance for the spring 320, preventing the spring 320 from shifting during extension and retraction (such as lateral bending), ensuring that the support 300 is subjected to uniform force, and avoiding support failure caused by excessive stress on one side.

[0034] In one embodiment, the snap-fit ​​connector 210 includes a third end plate 211 and a second bent plate 212; the two third end plates 211 are vertically aligned, one side of the lower third end plate 211 is connected to the support plate 220, and the second bent plate 212 is located on the side of the third end plate 211 connected to the support plate 220. The two third end plates 211 are connected by the second bent plate 212, and the inner surface of the second bent plate 212 is used to adhere to the outer surface of the first bent plate 113.

[0035] Specifically, the close fit between the second bent plate 212 and the first bent plate 113 increases the contact area between the snap-fit ​​connector 210 and the connector 110, resulting in a higher load-bearing capacity of the snap-fit ​​structure, making it suitable for conveying heavy industrial solid waste (such as steelmaking slag blocks). The upper and lower facing third end plate 211 forms a multi-layered stress structure with the first and second end plates of the connector 110, dispersing the material pressure into multiple stress points, avoiding local stress concentration (such as cracking at the edge of the first end plate 111), and extending the service life of the components. The arc-shaped structure of the second bent plate 212 is perfectly compatible with the first bent plate 113, with no sharp corner interference during the snap-fit ​​process, improving assembly and operational stability.

[0036] In one embodiment, a cover plate 214 is provided at the connection between the lower third end plate 211 and the support plate 220. The lower surface of the cover plate 214 is used to fit against the outer surface of the positioning tube 130. A flat plate 213 is connected to the top of the upper third end plate 211. The flat plate 213 is located directly above the second end plate 112.

[0037] Specifically, the plate 213 is located directly above the second end plate 112, which can block the connection gap between the second end plate 112 and the snap connector 210, preventing material debris (such as cement residue) from entering the gap and causing the snap connector to jam, thus reducing the cleaning frequency; the plate 213 can also help support the edge of the material (such as the cantilevered part of a long strip of solid waste), preventing the support 200 from tilting due to the drooping of the material edge, and improving the overall load-bearing stability of the support 200.

[0038] In one embodiment, a first inclined surface 1122 and a second inclined surface 2131 are respectively provided at the corners directly opposite to the first end plate 111 and the flat plate 213.

[0039] Specifically, the beveled design provides space for subsequent disassembly between the card connector 210 and the connector 110.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
