Description

Technical Field

[0001] This utility model relates to bulk material loading and unloading equipment, specifically to a non-powered dust removal device for bulk material loading and unloading. Background Technology

[0002] Currently, most bulk material handling equipment on the market is equipped with external dust collection systems to prevent dust from flying everywhere during loading and unloading. Non-powered bulk material handling equipment that does not require dust collectors is still in its early stages of development in China, mainly used for loading bulk materials such as grain, fertilizer, and chemical raw materials onto ships or trucks (ports, docks, factories, etc.). Currently, some bulk material handling operations lack dust collection equipment, resulting in a dirty and chaotic environment and significant material loss during loading and unloading. Others are equipped with dust collection systems, but these systems require frequent maintenance, and replacing filter elements is time-consuming and expensive. The dust collector fans also consume a lot of electricity, leading to high energy consumption, inefficiency, and high loading and unloading costs.

[0003] Similar problems have hindered bulk material transportation; high dust removal system costs increase the logistics costs of bulk material transportation. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a non-powered dust removal device for bulk material loading and unloading.

[0005] The purpose of this utility model is achieved through the following technical solution: a non-powered dust removal device for bulk material loading and unloading, comprising a cylinder and an upper cover plate. The cylinder includes a lower cone and an upper cylinder. The upper cover plate is provided with a feed inlet, and the bottom of the lower cone is a discharge outlet. A pneumatic double-gate unloading device is provided at the feed inlet. The pneumatic double-gate unloading device includes a connecting base, in which a gate frame is fixed. Two gates are provided in the gate frame. The gates can move in the track of the connecting base. The two gates are respectively connected to cylinders. The cylinders are fixed to the upper cover plate by cylinder brackets. A dust removal adjustment device is provided inside the cylinder. The dust removal adjustment device includes an outer cone and an inner cone. A screw is provided in the outer cone and the inner cone. A lower adjusting rotor is sleeved on the screw. A guide cover is provided below the feed inlet to divide the material into two streams.

[0007] A further improvement of this utility model is that an inspection door is also provided on the side wall of the upper cylinder.

[0008] A further improvement of this utility model is that a connecting bracket is also provided on the upper cover plate.

[0009] A further improvement of this utility model is that a rotary level switch is also provided on the upper cover plate.

[0010] A further improvement of this utility model is that a pilot-operated speed control valve is provided on the cylinder.

[0011] This utility model has the following advantages compared with the prior art: 1.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Elements and features described in one embodiment of this utility model can be combined with elements and features shown in one or more other embodiments. It should be noted that, for clarity, representations and descriptions of components and processes unrelated to this utility model and known to those skilled in the art are omitted in the description. 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.

[0016] A non-powered dust removal device for bulk material loading and unloading is made entirely of wear-resistant material. It includes a cylindrical body and an upper cover plate 3. The cylindrical body comprises a lower cone 1 and an upper cylindrical body 2, which are bolted together. The upper cover plate 3 has a feed inlet, and the bottom of the lower cone 1 is a discharge outlet. A pneumatic double-gate unloading device is installed at the feed inlet. The pneumatic double-gate unloading device includes a connecting base 4, in which a gate frame 5 is fixed. Two gates 6 are installed within the gate frame 5. The gates 6 can move within the track of the connecting base 4. The two gates 6 are respectively connected to a pneumatic... Cylinder 7 is fixed to the upper cover plate 3 by cylinder bracket 8. Cylinder 7 is equipped with pilot-operated speed regulating valve 18. The cylinder extends and retracts according to the electrical signal of the material level switch to control the feed rate and flow rate of the feed inlet. A dust removal regulating device is provided inside the cylinder to control the discharge flow rate and flow rate of the hopper. The dust removal regulating device includes an outer cone 9 and an inner cone 10. A screw 11 is provided in the outer cone 9 and the inner cone 10. A lower regulating rotor 12 is sleeved on the screw 11. A guide cover 13 is provided below the feed inlet to divide the material into two streams.

[0017] The upper cylinder 2 has a glass viewing window 14 on its side wall, allowing people to see the changes in the material level in the hopper with the naked eye; the cylinder 2 also has an inspection door 15 on its side wall, so that if you want to check the condition inside the equipment, you don’t have to remove the whole equipment from the machine, as the equipment itself has an inspection door that you can open to check.

[0018] The upper cover plate 3 is also equipped with a connecting bracket 16. The hopper is vertically hung on the boom of the ship loader through one hinge point on the left and one hinge point on the connecting bracket. Alternatively, the hopper can be fixed on the translation platform through several hinge points on the connecting bracket. The upper cover plate 3 is also equipped with a rotary level switch 17, which can detect the material level of the hopper.

[0019] During bulk material loading and unloading, the non-powered dust removal equipment is connected to the feeding belt conveyor via a connecting bracket. A pneumatic double-gate device opens the material gate, and the transported bulk material is poured into the equipment through the inlet. The material flow is first divided into two streams by a guide hood; the V-shaped inclined surface of the guide hood automatically separates the two streams, which continue to slide down along the two inclined surfaces of the V-shape. Then, they continue to slide down along the outer inclined surface of the outer cone of the dust removal regulating device. The material flow hits the inclined surface of the lower cone of the cylinder, where it is buffered and slowed down, resulting in a significant reduction in flow velocity. The material flow continues to slide down the inclined surface of the outer cone, and is further obstructed and its velocity reduced by passing through the gap between the outer cone and the lower cone of the cylinder. After passing through the gap, the material flow converges again from all directions along the inclined surface of the lower cone, forming a hollow material flow in which dust is trapped. The material flow and dust are finally loaded together into the ship or truck. The entire dust removal process is fully mechanized, requiring no power, thus achieving energy saving and cost reduction.

[0020] Different bulk materials have different sizes and shapes, so it is necessary to adjust the dust removal device inside the hopper to adjust the size of the gap through which the material flows, thereby reducing the flow rate and volume of the material and ensuring the best dust removal effect.

[0021] If the discharge speed of the cylinder is less than the feed speed, the material level can be seen gradually rising inside the upper cylinder through the glass viewing window. When the material level reaches the upper limit set by the level switch, the level switch sends an electrical signal, and the pneumatic double gate above, driven by the cylinder, closes the material gate slightly, thereby reducing the feed speed at the inlet. When the material level inside the upper cylinder falls below the upper limit, the pneumatic double gate actuates again, opening the material gate wider, thereby increasing the feed speed at the inlet, thus regulating the material level inside the upper cylinder in real time and preventing material blockage.

[0022] This invention achieves dust removal by adjusting the mechanical dust removal device inside the equipment, eliminating the need for power and thus achieving energy saving.

[0023] Finally, it should be noted that although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present invention as defined by the appended claims. Furthermore, the scope of the present invention is not limited to the specific embodiments of the processes, apparatus, means, methods, and steps described in the specification.
