Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying equipment, and relates to a material discharging device, in particular to an anti-blocking discharging device for fluffy materials. Background Art

[0002] A discharging device is an important equipment for material conveying, and it plays a crucial role in many fields such as construction, metallurgy, chemical industry, electric power, mines, etc. Fluffy materials refer to materials with a porous and fluffy structure, and their characteristics include large volume, low density, good fluidity, etc. When dealing with fluffy materials, special attention needs to be paid to their unique physical properties to ensure that the materials can maintain their original fluffy state during storage, transportation and discharging.

[0003] Due to the relatively large number of internal pores, fluffy materials have a larger volume and a lower density compared to materials of the same weight. The loose structure of fluffy materials makes them have good fluidity and are easy to flow in pipelines or containers.

[0004] In current industrial applications, although the fluffy material discharging devices meet the material handling requirements to a certain extent, there are still some significant drawbacks and deficiencies. When dealing with fluffy materials, these devices first face the difficulties of structural complexity and installation and debugging. Due to the particularity of fluffy materials, the discharging devices usually need to be designed more complexly to cope with the characteristics of good fluidity and easy blockage of the materials. This complexity not only increases the manufacturing and maintenance costs, but also makes the installation and debugging more cumbersome, affecting the overall working efficiency.

[0005] In terms of operation stability and reliability, the existing fluffy material discharging devices also expose some problems. Due to the large volume and low density of fluffy materials, uneven phenomena are likely to occur during the discharging process, resulting in material accumulation or blockage at the discharging port. In addition, some devices may have problems such as inflexible movement and jamming during operation, further affecting the discharging efficiency and the reliability of the equipment.

[0006] In terms of material handling efficiency and effect, the existing fluffy material discharging devices also have some limitations. For example, due to improper design or operation, some devices may have the problem of incomplete material discharging, resulting in material residue and waste. At the same time, the control of the discharging speed is also a difficult problem. For fluffy materials, too fast or too slow discharging speed may lead to material blockage or scattering, affecting the processing effect.

[0007] In terms of safety and environmental protection, the existing fluffy material unloading devices also have deficiencies. Since fluffy materials are prone to dust pollution during the unloading process, if the unloading device is not equipped with effective dust removal equipment or measures, it will have an adverse impact on the environment and the health of operators. In addition, some devices may neglect safety factors during design, such as randomly opening holes in the main beam of the unloading platform and having no anti-cutting rope measures for wire ropes passing through holes, which may lead to safety accidents.

[0008] From the perspective of usage cost and maintenance cost, the existing fluffy material unloading devices also have certain deficiencies. Some high-performance unloading devices have a high cost, increasing the equipment purchase cost. At the same time, due to their complex structure and many vulnerable parts, the maintenance costs of these devices are relatively high. This not only increases the operating costs of enterprises but also may affect the long-term stable operation of the equipment. Utility Model Content

[0009] To solve the above deficiencies in the existing technology, the present utility model aims to provide a fluffy material anti-blocking unloading device to achieve the purposes of improving the operation stability of the equipment, increasing the material processing speed of the equipment, reducing fine pollutants such as dust generated during material unloading, and at the same time reducing the equipment operation and maintenance costs.

[0010] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0011] A fluffy material anti-blocking unloading device includes a device main body and a power device. The device main body is hollow inside, with a feed inlet opened at the top and a discharge outlet opened at the bottom; a unloading mechanism is arranged inside the device main body, and the unloading mechanism includes a unloading rotating shaft and an adsorption tube; the unloading rotating shaft is a hollow tube shaft, movably sleeved outside the adsorption tube, and one end of the unloading rotating shaft far from the adsorption tube penetrates through one side of the device main body and is fixedly connected to the power output end of the power device; one end of the adsorption tube is sleeved inside the unloading rotating shaft and does not penetrate through the unloading rotating shaft, and the other end penetrates through and is fixed to the side of the device main body far from the power device and is communicated with an air compressor.

[0012] As a limitation of the present utility model, a plurality of unloading blocks are fixedly arranged along the circumference of the unloading rotating shaft, and adsorption holes are uniformly arranged along the axial direction of the unloading rotating shaft between every two unloading blocks.

[0013] By opening adsorption holes on the shaft body of the unloading rotating shaft and inserting an adsorption tube communicated with an air compressor inside it, the fluffy material can be adsorbed and unloaded during the unloading process. Through air pressure, the fluidity of the fluffy material is reduced, the unloading efficiency is improved, and at the same time, the large volume of the fluffy material is appropriately compressed through air pressure, avoiding the problem of material jamming in the equipment during the unloading process; and through the adsorption pressure generated inside the adsorption tube, the fine particulate pollutants such as dust or floating dust generated during the unloading of the fluffy material can be reduced.

[0014] As a further limitation of the present utility model, a filter element is provided in the middle of each adsorption hole, and the filter element is a filter net or a filter membrane.

[0015] By providing a filter element on the adsorption hole, it is possible to prevent some small-volume fluffy materials from being sucked into the adsorption pipe and affecting the discharging effect of the discharging device.

[0016] As another limitation of the present utility model, an air extraction groove is provided in the upper half of the adsorption pipe placed inside the discharging rotating shaft, and the opening length of the air extraction groove is matched with the number of adsorption holes opened along the length direction of the discharging rotating shaft.

[0017] The adsorption pipe is fixed to the equipment main body and will not rotate with the discharging rotating shaft. By opening an air extraction groove in the upper half of the adsorption pipe, it is possible to generate a suction force on the discharged material from the adsorption holes of the discharging rotating shaft when the discharging rotating shaft feeds, so that the material is more tightly adsorbed on the discharging rotating shaft. Subsequently, when the discharging rotating shaft rotates to the lower side of the adsorption pipe through the power device, the suction force of the adsorption hole disappears, so that the material naturally falls off from the discharging rotating shaft and flows out from the discharge port.

[0018] As the third limitation of the present utility model, the power device is a rotating motor.

[0019] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects obtained by the present utility model are:

[0020] (1) The present utility model relates to a discharging device for preventing blockage of fluffy materials. By opening adsorption holes on the shaft body of the discharging rotating shaft and inserting an adsorption pipe communicated with an air compressor inside it, it is possible to adsorb and unload fluffy materials during the discharging process, reduce the fluidity of fluffy materials through air pressure, improve the discharging efficiency, and at the same time appropriately compress the large volume of fluffy materials through air pressure, avoiding the problem of easy material jamming during the discharging process; and through the adsorption pressure generated in the adsorption pipe, it is possible to reduce the fine particle pollutants such as dust or floating dust generated during the unloading process of fluffy materials.

[0021] (2) The present utility model relates to a discharging device for preventing blockage of fluffy materials. By providing a filter element on the adsorption hole, it is possible to prevent some small-volume fluffy materials from being sucked into the adsorption pipe and affecting the discharging effect of the discharging device.

[0022] (3) The utility model relates to an anti-blocking discharging device for fluffy materials. The adsorption pipe is fixed on the equipment main body and will not rotate with the discharging rotating shaft. An air extraction groove is opened in the upper half of the adsorption pipe, which can enable the discharging rotating shaft to generate suction on the discharged materials from the adsorption holes of the discharging rotating shaft during feeding, so that the materials are more tightly adsorbed on the discharging rotating shaft. Then, when the discharging rotating shaft rotates to the lower side of the adsorption pipe through the power device, the suction of the adsorption holes disappears, so that the materials naturally fall off from the discharging rotating shaft and flow out from the discharge port.

[0023] In summary, the utility model provides an anti-blocking discharging device for fluffy materials, achieving the purpose of improving the operation stability of the equipment, enhancing the material processing speed of the equipment, reducing fine pollutants such as dust generated during material unloading, and at the same time reducing the equipment operation and maintenance costs.

[0024] The utility model is applicable to the anti-blocking discharging process of fluffy materials and is used for unloading fluffy materials. Brief Description of the Drawings

[0030] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and understanding the present utility model and are not used to limit the present utility model.

[0031] Embodiment An anti-blocking discharging device for fluffy materials

[0032] As Figures 1 to 3As shown in the figure, this embodiment includes a device main body 1 and a power device 5. The device main body 1 is hollow inside, with a feeding port 2 opened at the top and a discharging port 3 opened at the bottom. A discharging mechanism 4 is arranged inside the device main body 1. The discharging mechanism 4 includes a discharging rotating shaft 403 and an adsorption pipe 404. The discharging rotating shaft 403 is a hollow pipe shaft, movably sleeved outside the adsorption pipe 404. One end of the discharging rotating shaft 403 far from the adsorption pipe 404 penetrates through one side of the device main body 1 and is fixedly connected to the power output end of the power device 5. One end of the adsorption pipe 404 is sleeved inside the discharging rotating shaft 403 and does not penetrate through the discharging rotating shaft 403. The other end penetrates through and is fixed to the side of the device main body 1 far from the power device 5 and is communicated with an air compressor.

[0033] A plurality of discharging blocks 402 are fixedly arranged along the circumferential direction of the discharging rotating shaft 403. Adsorption holes 402 are uniformly arranged along the axial direction of the discharging rotating shaft 403 between every two discharging blocks 402.

[0034] A filter element is arranged in the middle of each adsorption hole 402. The filter element is a filter net or a filter membrane.

[0035] An air extraction groove 405 is arranged in the upper half of the adsorption pipe 404 placed inside the discharging rotating shaft 403. The opening length of the air extraction groove 405 is matched with the number of adsorption holes 402 opened along the length direction of the discharging rotating shaft 403.

[0036] The power device 5 is a rotating motor.

[0037] When using this embodiment, first start the air compressor to make an air pressure difference be generated between the inside and the outside of the discharging mechanism 4. After the fluffy material enters the feeding port 2, it is adsorbed between two discharging blocks 401 on the discharging rotating shaft 403 through the suction force generated by the air extraction groove 405 and the adsorption holes 402. Subsequently, start the motor device 5 to make the discharging rotating shaft 403 rotate towards the discharging port 3 of the device main body 1. When the part of the discharging rotating shaft 403 carrying the fluffy material turns to the discharging port, the adsorption holes 402 turn to the back of the air extraction groove 405, and the adsorption force on the adsorption holes 402 disappears. The fluffy material is separated from the discharging rotating shaft under its own gravity and falls out from the discharging port 3.

[0038] It should be noted that in addition to providing the adsorption force, the air compressor can also collect fine particle impurities such as dust and floating dust during the discharging process of the fluffy material. The impurities pass through the adsorption holes 402 and are separated from the fluffy material by the filter element arranged in the adsorption holes 402. Then they enter the air extraction groove 405 and flow towards the air compressor along the air flow direction. Therefore, a collection bin can be added between the air compressor and the device main body 1 to collect fine particle impurities such as dust and floating dust.

[0039] It should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
