Description

Technical Field

[0001] This utility model belongs to the technical field of ship loader equipment, specifically relating to a buffer dust suppression device at the head of a ship loader. Background Technology

[0002] Ship loaders mainly consist of a telescopic chute, lifting equipment, and control devices. Currently, most ship loaders rely on material falling freely from the telescopic chute to the loader head without any buffering or dust suppression devices. They depend entirely on a large dust collection system to collect dust from the loader head. While this can mitigate dust generation at the loader head to some extent, it is uneconomical, and dust may still occasionally overflow from the loader head due to high instantaneous output or during the movement of the loading head. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a buffer dust suppression device for the head of a ship loader.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a dust suppression buffer device for the head of a ship loader, comprising an outer cylinder, an outer soft cylinder connected to the upper end of the outer cylinder and an inner soft cylinder located circumferentially inside the outer soft cylinder, a dustproof soft cylinder provided circumferentially outside the lower end of the outer cylinder, an inner cylinder connected to the inner soft cylinder on the circumferentially inside the outer cylinder, a buffer conical cylinder extending to the lower end of the outer cylinder connected to the lower end of the inner cylinder, a variable diameter buffer cavity formed between the interior of the inner cylinder and the interior of the buffer conical cylinder, and a pressure-reducing cone located between the inner cylinder and the buffer conical cylinder within the variable diameter buffer cavity, a buffer straight cylinder for inserting into the material connected to the lower end of the buffer conical cylinder, the buffer straight cylinder not exceeding the lower end of the dustproof soft cylinder and connected to the variable diameter buffer cavity.

[0005] In the aforementioned ship loader head buffer dust suppression device, the outer cylinder is conical in shape and the diameter of the upper end of the outer cylinder gradually increases from the lower end to the upper end.

[0006] In the aforementioned ship loader head buffer dust suppression device, the inner cylinder and the outer cylinder are coaxially arranged and the upper end of the inner cylinder is fixedly connected to the upper end of the outer cylinder. The inner cylinder is conical and the diameter of the upper end of the inner cylinder gradually increases from the lower end to the upper end.

[0007] In the aforementioned ship loader head buffer dust suppression device, the buffer conical cylinder is coaxially and fixedly connected to the inner cylinder. The diameter of the upper end of the buffer conical cylinder connected to the inner cylinder is equal to the diameter of the lower end of the inner cylinder, and the diameter of the buffer conical cylinder gradually decreases from the upper end to the lower end.

[0008] In the aforementioned ship loader head buffer dust suppression device, the pressure-reducing cone is fixedly installed between the center of the inner cylinder and the center of the buffer cone-shaped cylinder. The pressure-reducing cone has a structure that is smaller at the top and larger at the bottom, and the pressure-reducing cone has a pressure-reducing cone surface on its circumferential outer side.

[0009] In the aforementioned ship loader head buffer dust suppression device, the inner cylinder has an inner conical surface located on the outer periphery of the pressure reducing cone surface and being smaller at the top and larger at the bottom, and the buffer conical cylinder has a buffer conical surface located on the outer periphery below the pressure reducing cone and being larger at the top and smaller at the bottom.

[0010] In the aforementioned ship loader head buffer dust suppression device, the buffer straight cylinder has a constant diameter structure and the diameter of the buffer straight cylinder is equal to the diameter of the lower end of the buffer conical cylinder.

[0011] In the aforementioned dust suppression device for the head of a ship loader, the lower end of the dustproof flexible cylinder extends to the inner circumferential side of the middle part of the dustproof flexible cylinder.

[0012] In the aforementioned dust suppression device for the head of a ship loader, the dustproof soft cylinder is formed by several dustproof soft curtains arranged circumferentially on the lower outer side of the outer cylinder.

[0013] In the aforementioned ship loader head buffer dust suppression device, a first annular cavity is formed between the inner circumferential side of the outer cylinder and the outer circumferential side of the inner cylinder, and the first annular cavity is connected to a second annular cavity between the inner circumferential side of the outer soft cylinder and the outer circumferential side of the inner soft cylinder.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: the material enters the variable diameter buffer chamber through the inner soft cylinder, is buffered by the internal pressure reducing cone, and then is buffered again by the buffer cone cylinder. Finally, the material is discharged through the buffer straight cylinder. At the same time, the buffer straight cylinder can be inserted into the material to achieve a dust reduction effect.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-2 As shown, a dust suppression device for the head of a ship loader includes an outer cylinder 1, an outer flexible cylinder 2 connected to the upper end of the outer cylinder 1, and an inner flexible cylinder 3 located circumferentially inside the outer flexible cylinder 2. A dustproof flexible cylinder 4 is provided circumferentially outside the lower end of the outer cylinder 1. Preferably, the dustproof flexible cylinder 4 is formed by a plurality of dustproof soft curtains 41 arranged circumferentially outside the lower end of the outer cylinder 1, which block dust. The outer cylinder 1 is provided circumferentially inside the inner flexible cylinder 3. The inner cylinder 5 is connected to the outer cylinder 1, and a buffer conical cylinder 6 extending to the lower outer side of the outer cylinder 1 is connected to the lower end of the inner cylinder 5. A variable diameter buffer cavity 7 is formed between the interior of the inner cylinder 5 and the interior of the buffer conical cylinder 6. The variable diameter buffer cavity 7 contains a pressure-reducing cone 8 located between the inner cylinder 5 and the buffer conical cylinder 6. The lower end of the buffer conical cylinder 6 is connected to a buffer straight cylinder 9 for inserting into the material. The buffer straight cylinder 9 does not extend beyond the lower end of the dustproof soft cylinder 4 and is connected to the variable diameter buffer cavity 7. Both the outer soft cylinder 2 and the inner soft cylinder 3 are made of canvas. The material enters the variable diameter buffer cavity 7 through the inner soft cylinder 3, is buffered by the pressure-reducing cone 8, and then is buffered again by the buffer conical cylinder 6. Finally, the material is discharged through the buffer straight cylinder 9. At the same time, the buffer straight cylinder 9 can be inserted into the material to achieve a dust reduction effect.

[0020] In this embodiment, the outer cylinder 1 is conical and its diameter gradually increases from the upper end to the lower end. The inner cylinder 5 is coaxially arranged with the outer cylinder 1 and its upper end is fixedly connected to the upper end of the outer cylinder 1. The inner cylinder 5 is also conical and its diameter gradually increases from the upper end to the lower end.

[0021] Furthermore, the buffer conical cylinder 6 is coaxially and fixedly connected to the inner cylinder 5. The diameter of the upper end of the buffer conical cylinder 6 connected to the inner cylinder 5 is equal to the diameter of the lower end of the inner cylinder 5, and the diameter of the buffer conical cylinder 6 gradually decreases from the upper end to the lower end. Obviously, the inner cylinder 5 has a structure that is smaller at the top and larger at the bottom, and the buffer conical cylinder 6 has a structure that is larger at the top and smaller at the bottom. The two are connected to form a variable diameter buffer cavity 7 inside.

[0022] Furthermore, the pressure-reducing cone 8 is fixedly disposed between the center of the inner cylinder 5 and the center of the buffer conical cylinder 6. The pressure-reducing cone 8 has a structure that is smaller at the top and larger at the bottom, and the pressure-reducing cone 8 has a pressure-reducing cone surface 81 on the outer circumference. The pressure-reducing cone 8 can be a conical cylinder or a square cone cylinder. By fixing the pressure-reducing cone 8 between the center of the inner cylinder 5 and the center of the buffer conical cylinder 6, the pressure-reducing cone surface 81 plays a buffering role when the material falls.

[0023] The inner cylinder 5 has an inner conical surface 51 located on the outer periphery of the pressure-reducing conical surface 81, which is smaller at the top and larger at the bottom. The buffer conical cylinder 6 has a buffer conical surface 61 located on the outer periphery of the pressure-reducing conical surface 8, which is larger at the top and smaller at the bottom. The material falling from the direction of the pressure-reducing conical surface 81 is subjected to secondary buffering through the buffer conical surface 61.

[0024] To achieve dust suppression, the lower end of the dustproof flexible cylinder 4 extends to the inner circumferential side of the middle part of the dustproof flexible cylinder 4, and the buffer straight cylinder 9 has a constant diameter structure, with its diameter equal to the diameter of the lower end of the buffer conical cylinder 6. The buffer straight cylinder 9 can be inserted into the material to achieve dust suppression.

[0025] Preferably, a first annular cavity 11 is formed between the inner cylinder 1 (circumferentially inward) and the inner cylinder 5 (circumferentially outward), and the first annular cavity 11 is connected to a second annular cavity 21 between the outer flexible cylinder 2 (circumferentially inward) and the inner flexible cylinder 3 (circumferentially outward). The airflow generated after the material falls can enter the second annular cavity 21 through the first annular cavity 11.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0027] Although this document frequently uses terms such as outer cylinder 1, first annular cavity 11, outer soft cylinder 2, second annular cavity 21, inner soft cylinder 3, dustproof soft cylinder 4, dustproof soft curtain 41, inner cylinder 5, inner cylinder conical surface 51, buffer conical cylinder 6, buffer conical surface 61, variable diameter buffer cavity 7, pressure reducing cone 8, pressure reducing cone surface 81, and buffer straight cylinder 9, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
