Description

Technical Field

[0001] This utility model relates to the field of general machinery, and in particular to a conveying device for material distribution using an external small coal hopper. Background Technology

[0002] In industrial production, coal serves as a core energy source and raw material, and the stability of its allocation and transportation directly impacts production efficiency. Current coal transportation largely relies on fixed belt conveyors and single-bucket elevators. These devices are mostly integrated designs, with fixed hoppers and conveying paths, enabling only directional transport of a single material along a single path. In scenarios requiring multi-coal blends, such as thermal power generation, coking, and coal chemical industries, multiple independent conveying devices must operate in parallel, or manual assistance must be used to switch material channels to meet different blending requirements. As industrial production demands increasing precision in material blending and flexibility in production processes, the structural limitations of traditional conveying devices are becoming increasingly apparent. They struggle to adapt to the diverse allocation needs under complex operating conditions, necessitating a flexible, expandable, and precisely controllable conveying solution.

[0003] The core defects of the existing technology are: the existing hopper and conveying structure are fixed, there is no external expansion and multi-channel confluence design, it is impossible to realize the synchronous allocation of multiple coal types, the material ratio is simple, and the switching and material control accuracy is poor, making it difficult to adapt to complex ratio scenarios. Utility Model Content

[0004] The purpose of this utility model is to provide an external small coal hopper material mixing and conveying device, which aims to solve the problems mentioned above, such as the fixed hopper and conveying structure of the existing technology, the lack of external expansion and multi-channel confluence design, the inability to achieve synchronous mixing of multiple coal types, the single material ratio, and the poor switching and material control accuracy, making it difficult to adapt to complex mixing scenarios.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An external small coal hopper material handling and conveying device includes:

[0007] A fixed bracket, which consists of three fixed frames;

[0008] The main hopper is installed inside the fixed bracket;

[0009] External coal hoppers are installed on the outside of the main hopper, and there are three sets of external coal hoppers;

[0010] A quick-change mechanical joint is installed between the main hopper and the external coal hopper;

[0011] A multi-port manifold is installed on the lower side of the main hopper.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of this utility model, an auxiliary support arm is installed between the fixed bracket and the external coal hopper.

[0014] In one embodiment of this utility model, reinforcing ribs are installed on the outer side of the main hopper.

[0015] In one embodiment of this utility model, an anti-stick liner is installed on the inner side of the main hopper.

[0016] In one embodiment of this utility model, the input end of the multi-port manifold is fixedly connected to the external coal hopper via a feeding pipe.

[0017] In one embodiment of this utility model, the output end of the multi-port manifold is fixedly connected to the upper side of the screw feeder, and the inner side of the screw feeder is equipped with screw blades.

[0018] In one embodiment of this utility model, an annular sealing ring is installed at the connection between the multi-port manifold and the screw feeder.

[0019] In one embodiment of this utility model, a gate valve is installed at both the input and output ends of the multi-port manifold.

[0020] Compared with existing technologies, the beneficial effects of this utility model are reflected in the following aspects: By adding three sets of external coal hoppers to the outside of the main hopper, different types of coal materials can be carried simultaneously, expanding the supply sources and thus improving the diversity of material allocation. Quick-change mechanical joints connect the main hopper and the external coal hoppers, enabling rapid disassembly and switching of hoppers and adapting to multiple coal types for rotation, meeting flexible proportioning needs. Multi-channel manifolds coordinate the material conveying of the main hopper and each external coal hopper, achieving centralized convergence and precise mixing of materials from multiple paths, solving the problem of complex proportioning and mixing. A stable connection between the multi-channel manifold and the external coal hoppers ensures smooth material conveying, avoids leakage and loss, and ensures sufficient supply of proportioning raw materials. The multi-channel manifold is equipped with gate valves at the input and output ends, allowing independent control of the on / off state of each channel and precise regulation of material flow, improving proportioning accuracy. The screw feeder, combined with the rotating screw blades, enables quantitative material output and stable control of the supply, ensuring accurate and consistent proportioning. The annular sealing ring seals the connection between the multi-port manifold and the screw feeder, preventing material leakage and air ingress, avoiding proportion deviations, and further enhancing the accuracy of mixing.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the shape, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] It should be noted that the existing material mixing and conveying device for external small coal hoppers has the following core defects: the existing technology has a fixed hopper and conveying structure, without external expansion or multi-channel confluence design, making it impossible to achieve synchronous mixing of multiple coal types, resulting in a single material ratio, poor switching and material control accuracy, and difficulty in adapting to complex mixing scenarios. To address this, a material mixing and conveying device for external small coal hoppers is proposed, comprising a fixed support 10, which consists of three fixed frames; a main hopper 20, installed inside the fixed support 10; external coal hoppers 30, installed outside the main hopper 20, with three sets of external coal hoppers 30; a quick-change mechanical joint 40, installed between the main hopper 20 and the external coal hoppers 30; and a multi-channel confluence joint 50, installed below the main hopper 20.

[0033] In one embodiment, an auxiliary support arm 11 is installed between the fixed bracket 10 and the external coal hopper 30.

[0034] In one embodiment, a reinforcing rib 21 is installed on the outer side of the main hopper 20. The reinforcing rib is fixed to the outer wall of the main hopper and forms a rigid connection with the main hopper body. By increasing the thickness of the hopper wall and its equivalent strength, the deformation resistance of the main hopper when carrying materials is improved, and the hopper is prevented from bulging or cracking due to long-term load.

[0035] In one embodiment, an anti-stick liner 22 is installed on the inner side of the main hopper 20. The anti-stick liner is tightly fitted to the inner wall of the main hopper. Its smooth surface reduces the adhesion between the coal and the inner wall of the hopper, allowing the material to slide smoothly under the action of gravity, avoiding accumulation and blockage in the main hopper, and ensuring feeding efficiency.

[0036] In one embodiment, the input end of the multi-port manifold 50 is fixedly connected to the external coal hopper 30 via a feeding pipe 51.

[0037] In one embodiment, the output end of the multi-port manifold 50 is fixedly connected to the upper side of the screw feeder 52. The screw feeder 52 is equipped with a screw blade 53 on its inner side. The screw blade introduces the mixed material into the screw feeder through the manifold. When the screw blade rotates, it cooperates with the inner wall of the feeder to push the material evenly to the output end, thereby realizing the quantitative conveying of the material and ensuring a stable supply of the proportioned material.

[0038] In one embodiment, an annular sealing ring 54 is installed at the connection between the multi-port manifold 50 and the screw feeder 52. The annular sealing ring is embedded in the connection gap between the two and fills the gap through its own elastic deformation, preventing material leakage from the connection during the conveying process. At the same time, it prevents outside air from entering and affecting the material ratio accuracy, ensuring the sealing of the material conveying.

[0039] In one embodiment, a gate valve 55 is installed at both the input and output ends of the multi-port manifold 50.

[0040] In one embodiment, see Figure 1 and Figure 2 The auxiliary support arm 11 is connected to the fixed bracket 10 and the external coal hopper 30 at both ends, respectively. The gravity generated when the external coal hopper 30 carries materials is distributed to the fixed bracket 10. Through the rigid connection of the three, the installation stability of the external coal hopper 30 is enhanced, providing a stable structural foundation for the subsequent material to be conveyed through the feeding pipe 51, and avoiding the impact of the shaking of the external coal hopper 30 on the stability of material conveying.

[0041] In one embodiment, the material stored in the external coal hopper 30 enters the feeding pipe 51 under the action of gravity. The feeding pipe 51 serves as a connecting channel, guiding the material from each external coal hopper 30 to the multi-channel manifold 50. With the fixed connection between the feeding pipe 51 and the two, it is ensured that the material from multiple paths can be accurately channeled into the multi-channel manifold 50, achieving the initial concentration of different coal types and preparing for subsequent proportioning adjustments.

[0042] In another embodiment, see Figure 3 The slide gate valve 55 is installed at the input and output ends of the multi-port manifold 50. The slide gate valve at the input end can individually control the amount of material entering the manifold through the feed pipe 51 from the corresponding external coal hopper 30. The slide gate valve at the output end regulates the total output of the mixed material. By adjusting the opening and closing degree of each slide gate valve, the precise proportioning and total amount control of multiple coal types in the confluence process can be achieved, ultimately meeting the requirements of complex material proportioning.

[0043] In summary, the material conveying device for material distribution using an external small coal hopper of this utility model can flexibly realize the synchronous supply and precise distribution of multiple coal types through the coordinated action of the external coal hopper 30, the multi-channel manifold 50, the feeding pipe 51 and the slide valve 55, meet the needs of complex material proportioning scenarios, and improve the diversity and accuracy of material distribution.

[0044] Working Principle: The fixed support structure forms a stable support structure through three fixed frames. The main hopper is installed inside to carry the basic coal material. Three sets of external coal hoppers are assembled on the outside through quick-change mechanical joints to achieve simultaneous storage of multiple coal types. The auxiliary support arm distributes the load of the external coal hoppers to the fixed support. The reinforcing ribs on the outside of the main hopper improve the overall structural stability and prevent deformation or shaking when the material is loaded. The anti-stick lining plate inside the main hopper reduces coal adhesion and ensures smooth material feeding. The material in each external coal hopper is directionally conveyed to the multi-way manifold under the main hopper through the feeding pipe, realizing the centralized convergence of multi-path material. The gate valves at the input and output ends of the multi-way manifold control the feed rate of each coal type and the total output of the mixture, respectively. The converged material is introduced into the screw feeder, where the rotation of the screw blades achieves quantitative conveying. The annular sealing ring at the connection ensures a leak-proof seal. Finally, through the coordinated operation of all components, flexible proportioning and precise conveying of multiple coal types can be achieved to meet the needs of complex material blending scenarios.
