Description

Technical Field

[0001] This utility model relates to the field of loading and unloading auxiliary equipment, and in particular to a safe unloading device for bulk materials. Background Technology

[0002] Currently, most bulk material silo unloading devices are simple, manually operated opening mechanisms. While inexpensive, they must be opened manually or with tools. If the device malfunctions, large amounts of material can bury workers inside, causing asphyxiation. Motor-controlled opening mechanisms, because they do not meet corrosion and explosion-proof safety requirements, can only be installed externally, which in turn results in the silo's airtightness and insulation failing to meet standards. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the material silo unloading device is a simple manual opening device, which poses a safety hazard. The motor is installed outside the material silo, which causes the airtightness and heat preservation of the material silo to fail to meet the standards. This utility model provides a safe unloading device for bulk materials.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A safe unloading device for bulk materials includes a corrosion-resistant and explosion-proof servo electric device, a telescopic rod, a discharge port cover, and an insulated and airtight door for the outer discharge port of the silo. The corrosion-resistant and explosion-proof servo electric device is installed on the inner side of the outer wall of the silo. An inclined discharge channel is provided on the outer wall of the silo. The upper end of the inclined discharge channel is located on the inner side of the outer wall of the silo, and the lower end is located on the outer side of the outer wall of the silo. A discharge port cover is provided at the upper end. The discharge port cover is connected to the corrosion-resistant and explosion-proof servo electric device through the telescopic rod. The extension length of the telescopic rod is controlled by the corrosion-resistant and explosion-proof servo electric device. When the telescopic rod is extended to its maximum length, the discharge port cover covers the entire upper end. When the telescopic rod is extended to its minimum length, the upper end is not covered. An insulated and airtight door for the outer discharge port of the silo is provided at the lower end.

[0006] Furthermore, the inclined angle of the inclined discharge channel is 45°.

[0007] Furthermore, the number of inclined discharge channels can be one, two, or more.

[0008] Furthermore, the discharge port cover plate is tightly fitted with the upper port to form the first layer of heat-insulating and airtight door.

[0009] Furthermore, the insulated and airtight door at the outlet of the warehouse forms a second layer of insulated and airtight door with the lower port. A hinge door is provided on the insulated and airtight door at the outlet of the warehouse, which can be opened electrically or manually.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model has high safety. It avoids the risk of workers being buried by bulk materials during close-range manual operation, resulting in suffocation and personal injury accidents;

[0012] 2. The insulation and airtightness of the bulk material silo of this utility model are greatly improved. It adopts a corrosion-resistant and explosion-proof servo electric device, which is installed inside the bulk material silo. The discharge port cover plate and the discharge port form the first layer of insulation and airtight door, and a second layer of insulation and airtight door is installed on the outside of the material silo.

[0013] 3. The electric actuator of this utility model has strong expandability. The motor power unit adopts a corrosion-resistant and explosion-proof servo electric actuator, which can accurately control the extension distance and can be connected to remote control devices and Internet of Things systems.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0020] Example:

[0021] Reference Figures 1 to 4 This embodiment describes a safe unloading device for bulk materials.

[0022] One, two, or more 45° discharge channels are opened on the outer wall of the bulk material silo. Corrosion-proof and explosion-proof servo electric device 1 is installed on the inner side of the outer wall 7 of the bulk material silo. The corrosion-proof and explosion-proof servo electric device 1 is connected to the discharge port cover plate 3 through the telescopic rod 2. The telescopic length of the telescopic rod 2 is controlled and fixed by the program. When it is extended to the longest length, the discharge port cover plate 3 can completely cover the upper port. When it is extended to the shortest length, the lower port can be fully exposed.

[0023] Specifically, when the anti-corrosion and explosion-proof servo electric device 1 drives the telescopic rod 2 to retract, the discharge port cover 3 moves accordingly. When the discharge port cover 3 does not cover the upper port, the upper port is in an open state. At this time, the hinge door 6 of the insulated and airtight door 5 of the warehouse discharge port also opens, and the material begins to flow, thus realizing the discharge function.

[0024] Specifically, when the anti-corrosion and explosion-proof servo electric device 1 drives the telescopic rod 2 to extend, the discharge port cover 3 moves accordingly. When the discharge port cover 3 covers the entire upper port, the upper port is closed and the material stops flowing. After all the material in the discharge channel has been discharged, the hinge door 6 of the insulated and airtight door 5 of the warehouse can be closed to realize the function of stopping the discharge.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
