Description

Technical Field

[0001] This utility model relates to the technical field of roasting ash treatment equipment, and in particular to a tubular chain conveyor device adapted for ash discharge. Background Technology

[0002] In industrial production, the ash generated after roasting and combustion processes needs to be collected, transported, and stored. In existing ash disposal operations, open belt conveyors and poorly sealed screw conveyors are often used for material transfer. Since roasting ash is usually in the form of fine powder, it is light and can fly around. When the above-mentioned conveying methods are used, a large amount of dust will be generated during the material feeding, conveying, and discharging stages. This not only wastes materials but also seriously pollutes the production site and the surrounding environment, posing a threat to the health of operators.

[0003] Furthermore, when ash needs to be transported from outdoor work areas to indoor storage silos, the transport path often involves both horizontal and vertical transitions. Traditional single conveying equipment is difficult to adapt to such complex path requirements. If multiple devices are combined, the transfer interfaces between the devices will become new dust leakage points, increasing the complexity and failure rate of the system, and requiring a large footprint. At the same time, existing conveying devices usually only have a single material displacement function and lack the ability to purify and treat fine particles that may be mixed in the ash, which will affect the quality of subsequent ash utilization.

[0004] Therefore, this utility model proposes a tubular chain conveyor device adapted for ash discharge to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing tubular chain conveyor devices adapted for ash discharge, such as the tendency to generate dust spillage and cause environmental pollution when conveying powdery materials, and the difficulty in achieving fully enclosed automated continuous conveying, this utility model aims to provide a tubular chain conveyor device adapted for ash discharge with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a tubular chain conveyor device adapted for ash discharge, including: an indoor bin, an outdoor bin, a supply mechanism and a conveying mechanism; and a dust collector installed in the outdoor bin.

[0007] The discharge end of the supply mechanism is connected to the inlet end of the dust collector, and the discharge end of the dust collector is connected to the inlet end of the conveying mechanism. By integrating the dust collector into the outdoor warehouse and using it as the connection hub between the supply mechanism and the conveying mechanism, a fully enclosed purification and transfer structure is formed.

[0008] Preferably, the supply mechanism includes a feed hopper, a supply chain, a pullback chain, a first supply motor, and a second supply motor. The supply chain and the pullback chain together form a closed loop for cyclic conveying. A portion of the supply chain passes through the bottom of the feed hopper, and another portion extends to the feed end of the dust collector.

[0009] Preferably, the conveying mechanism includes a lifting tube chain, a falling tube chain, a first conveying motor, and a second conveying motor. The lifting tube chain and the falling tube chain together form a closed loop for cyclic lifting, and the discharge end of the lifting tube chain is located above the indoor silo.

[0010] Preferably, the conveying mechanism has a base for temporarily collecting ash at the feed end of the lifting tube chain, and the second conveying motor is used to drive the movement of the lifting tube chain at the base.

[0011] Preferably, the conveying mechanism further includes a ash hopper and a tube, with the discharge end of the lifting tube chain located above the ash hopper, and the lower outlet of the ash hopper connected to the tube.

[0012] Preferably, the end of the cannula extends into the indoor compartment and points towards the center of the indoor compartment.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problem of open structure of existing ash discharge devices and easy dust overflow during the conveying process by setting up a supply mechanism, a conveying mechanism and an outdoor silo with an internal dust collector for closed connection. It achieves the technical effect of fully automated and fully enclosed conveying of ash from feeding to silo, effectively avoiding dust leakage and protecting the production environment.

[0015] 2. This utility model solves the problem of existing technology directly conveying ash containing impurities, which affects its utilization quality and wears down the equipment, by setting a dust collector at the transfer connection between the supply mechanism and the conveying mechanism to pre-purify the ash. This achieves the technical effect of improving the quality of ash, reducing the wear of subsequent conveying components, and extending the overall service life of the device.

[0016] 3. This utility model solves the problems of simple discharge method, difficult control of discharge position and easy generation of secondary dust in the prior art by setting ash hopper and insertion pipe at the discharge end of the conveying mechanism. It achieves the technical effect of accurately and centrally discharging ash to the center of the indoor warehouse, reducing dust in the unloading process and facilitating the uniform stacking of materials in the warehouse.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example:

[0025] Please refer to Figures 1 to 4 This utility model provides a tubular chain conveyor device adapted for ash discharge, which aims to solve the problem that existing ash discharge devices are prone to dust overflow when conveying powdery materials and are difficult to achieve fully enclosed automated continuous conveying.

[0026] like Figure 1 and Figure 2As shown, the ash-adaptive tubular chain conveyor includes an indoor silo 1, an outdoor silo 2, a supply mechanism 4 located on one side of the outdoor silo 2, and a conveying mechanism 3 connecting the outdoor silo 2 and the indoor silo 1. The indoor silo 1 is used for final storage of ash, and the outdoor silo 2 serves as a closed cavity for intermediate processing and transfer. The supply mechanism 4 is used to continuously transport external ash into the outdoor silo 2, and the conveying mechanism 3 is used to vertically lift and transport the ash processed by the outdoor silo 2 into the indoor silo 1. The supply mechanism 4 and the conveying mechanism 3 work together to form a fully enclosed conveying system from feeding to silo entry.

[0027] To solve the above-mentioned technical problems, the technical solution of this embodiment is that a dust collector 44 is fixedly connected inside the outdoor warehouse 2 by a bracket, and the dust collector 44 forms a purification function connection between the supply mechanism 4 and the conveying mechanism 3.

[0028] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The structure will be described in detail below:

[0029] The supply mechanism 4 includes a feed hopper 41, a supply chain 42, a return chain 43, a first supply motor 45, and a second supply motor 46. The feed hopper 41 is used to receive external roasting ash to be conveyed. The first supply motor 45 and the second supply motor 46 are fixed to the frame of the supply mechanism 4 by bolts and jointly drive the supply chain 42 and the return chain 43 to circulate. The supply chain 42 and the return chain 43 together form a closed loop for circulatory conveying. A part of the supply chain 42 passes through the lower part of the feed hopper 41, and its discharge end extends into the interior of the outdoor silo 2 and is connected to the feed end of the dust collector 44 by a flange sealing connection.

[0030] The dust collector 44 pre-purifies the roasting ash conveyed by the supply chain 42 to remove fine particles. The purified ash is discharged from the discharge end of the dust collector 44 under gravity and falls into the feed end of the conveying mechanism 3. The feed end of the conveying mechanism 3 is a base for temporarily collecting ash, which is located directly below the discharge end of the dust collector 44. This structure, which integrates the dust collector 44 into the outdoor silo 2 and makes it the connecting hub between the supply mechanism 4 and the conveying mechanism 3, ensures that the ash can be effectively purified before it is transferred from horizontal conveying to vertical lifting. The entire transfer process is completed in the enclosed space of the outdoor silo 2, effectively preventing dust leakage.

[0031] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0032] As a preferred embodiment, please refer to Figure 3The conveying mechanism 3 includes a lifting pipe chain 33, a return pipe chain 34, a first conveying motor 31, and a second conveying motor 32. The first conveying motor 31 and the second conveying motor 32 are respectively fixedly installed on the frame at both ends of the conveying mechanism 3, and together drive the lifting pipe chain 33 and the return pipe chain 34 to circulate. The lifting pipe chain 33 and the return pipe chain 34 together form a closed loop for cyclic lifting. The second conveying motor 32 is used to drive the lifting pipe chain 33 at the base to move and lift the ash collected in the base upward. The first conveying motor 31 drives the lifting pipe chain 33 to turn at the top.

[0033] As another preferred embodiment, in order to achieve precise delivery of ash into indoor chamber 1, please refer to... Figure 1 and Figure 3 The conveying mechanism 3 also includes an ash hopper 35 and a tube 36. The ash hopper 35 is fixed below the discharge port at the head of the conveying mechanism 3 by welding or bolting. It is used to collect the ash discharged from the discharge end of the lifting tube chain 33. The ash hopper 35 has a funnel-shaped structure that is wider at the top and narrower at the bottom. Its lower outlet is fixedly connected to the inlet end of the tube 36. The end of the tube 36 extends into the inner chamber 1 and points to the center of the inner chamber 1, thereby ensuring that the ash can be concentrated and stably sent into the designated area inside the chamber.

[0034] Working principle: When using, first confirm that the interface between the indoor chamber 1 and the outdoor chamber 2 is without gaps and well sealed, that the connection between the lifting pipe chain 33, the falling pipe chain 34 and the ash hopper 35 of the conveying mechanism 3 is stable, and that the supply pipe chain 42 and the pull-back pipe chain 43 of the supply mechanism 4 are not stuck. Then pour the roasted ash to be conveyed into the feed hopper 41 of the supply mechanism 4, ensuring that the ash does not exceed the rated capacity of the feed hopper 41. Start the first supply motor 45 and the second supply motor 46. The first supply motor 45 and the second supply motor 46 output power to drive the supply pipe chain 42 and the pull-back pipe chain 43 to run along the preset track. The supply pipe chain 42 drives the ash in the feed hopper 41 to be smoothly conveyed towards the outdoor chamber 2 through the internal conveying blades. The first supply motor 45 and the second supply motor 46 simultaneously drive the pull-back pipe chain 43 to run in the opposite direction. The pull-back pipe chain 43 pulls the conveying blades in the supply pipe chain 42 back to the second supply motor 46, completing the circulation of the conveying blades inside the supply pipe chain 42 and the pull-back pipe chain 43.

[0035] After the ash is transported to the outdoor chamber 2 through the supply chain 42, the first supply motor 45 will transport the roasted ash from the bottom into the dust collector 44. The dust collector 44 pre-purifies the roasted ash to remove fine particles. The pre-treated ash falls into the second conveyor motor 32 of the conveying mechanism 3 under gravity. The second conveyor motor 32 temporarily collects the ash to prevent it from scattering. The first conveyor motor 31 and the second conveyor motor 32 are started. The first conveyor motor 31 and the second conveyor motor 32 simultaneously drive the conveying blades inside the lifting chain 33 and the falling chain 34 to rotate. The bottom of the first conveyor motor 31 is connected to the top of the insertion tube 36 through the ash collection hopper 35, which transfers the ash transported by the lifting chain 33 to the first conveyor motor 31. The ash falls from the bottom opening of the first conveyor motor 31 into the ash collection hopper 35, and then slides along the ash collection hopper 35 into the insertion tube 36 until the ash reaches the center of the indoor chamber 1.

[0036] The outdoor compartment 2 is designed to enclose the connection between the dust collector 44, the second conveyor motor 32, and the first supply motor 45, to prevent dust leakage or air ingress in the connection area, ensure the overall sealing of the device, and realize the cyclic conveying and processing of ash.
