In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-2The utility model provides an embodiment: a sintering batching room silo anti-sticking device, comprising a sintering silo 1, a double-row backflush pipe 2, a compressed air dehydrator 4, and a vibrating device 5. The sintering silo 1 is a conical structure. The sintering silo 1 is used as a container for mainly storing and processing sintering materials. The conical structure is conducive to the flow and discharge of materials. A vibrating device 5 is arranged on the conical end of the bottom of the sintering silo 1. Double-row backflush pipes 2 are arranged at different heights on the circumference of the conical end of the sintering silo 1. The double-row backflush pipes 2 are located on the circumference of the conical end of the sintering silo 1 and are used to provide compressed air to backflush the inner wall of the silo to prevent material adhesion. Compressed air is used as a power source to backflush the inside of the silo. An outlet pipe is provided at the other end of the exhaust backblowing pipe 2, and a pneumatic valve 3 is provided on the outlet pipe. A compressed air dehydrator 4 is provided at the other end of the outlet pipe. The compressed air dehydrator 4 is used to purify the compressed air, ensure the dryness of the backblowing gas, and prevent the influence of moisture on the raw materials in the silo. When the compressed air passes through the dehydrator, its temperature is reduced to below the dew point, and the water vapor condenses into liquid water in the condenser, and then is discharged through the drain port, thereby achieving the purpose of dehydration. An inlet pipe is provided on the compressed air dehydrator 4, and the outlet pipe and the inlet pipe are set at different heights. The outlet on the right side of the drainer is 20 cm higher than the inlet on the left side. Setting the outlet pipe at a higher position than the inlet pipe can effectively prevent the reflux or mixing of gas or liquid. This design ensures that the gas or liquid flows along the predetermined path without backflow or mixing, thereby maintaining the stability and performance of the system. The setting of the air outlet pipe being higher than the air inlet pipe can promote the smooth discharge of gas. Due to the effect of gravity, the outlet is higher than the inlet, which can make the gas flow to the outlet more easily, thereby improving efficiency and preventing gas backflow. A valve is provided on the compressed air dehydrator 4, and the valve controls the opening or closing of the dehydration port of the compressed air dehydrator 4. Compressed air is widely used in steel plants. The compressed air is connected from the left side of the drainer and discharged from the right side. The water is regularly discharged from the lower cone section valve to discharge the water and eliminate the influence of the compressed air source on the moisture content of the raw materials in the silo. There is also a valve on the base. There is a material trough, which is arranged corresponding to the opening at the bottom of the conical end of the sintering silo 1 for dropping the material. The bottom end of the compressed air dehydrator 4 is arranged in a conical structure, and a dehydration port is opened at the bottom of the conical end. A backblowing nozzle is arranged at the top of the double-row backblowing pipe 2, and the backblowing nozzle is arranged toward the inner wall of the sintering silo 1. The backblowing nozzle is arranged toward the inner wall to ensure that the backblowing gas directly impacts the inner wall of the silo, more effectively removes the material adhering to the inner wall, improves the cleaning effect, and can ensure that the backblowing gas evenly covers all parts of the inner wall of the silo to avoid dead corners, thereby more thoroughly removing the adhering material.

[0023] Example 2: Please refer to Figure 3 , based on Example 1, it also has the following structure:

[0024] The vibration device 5 includes a shell, which provides external protection and a supporting structure for the vibration device 5 to ensure the stability and safety of the vibration device 5. The base and the vibrator generate mechanical vibrations, which are transmitted to the sintering silo 1 to promote the uniform distribution and flow of materials in the silo to avoid sticking to the inner wall of the silo. The shock-absorbing spring buffers the vibration and impact generated by the vibration device 5, reduces the transmission of vibration to the surrounding environment or other equipment, protects the equipment and reduces vibration noise. A protective groove is provided on the shell, and a plurality of shock-absorbing springs are provided on the protective groove. A connecting plate 501 is provided on the top of the shock-absorbing spring, and the connecting plate 501 connects the top of the shock-absorbing spring to the conical end of the sintering silo 1 to ensure the effective connection between the vibration device 5 and the silo. The connecting plate 501 is circumferentially connected to the conical end of the sintering silo 1. A vibration ring is sleeved on the bottom of the conical end. The vibration ring connects the vibrator to the sintering silo 1 and transmits the vibration force into the silo. The vibration ring is connected to the vibrator and driven by the drive motor 502. The drive motor 502 provides power to drive the vibrator to generate the required mechanical vibration. The bottom of the vibrator is fixedly connected to the base. A number of hydraulic rods and springs are arranged between the base and the shell. The hydraulic rods and springs form a shock-absorbing and buffering system between the base and the shell to further reduce vibration transmission and protect the equipment. The opening size of the protective groove does not exceed the circumference of the bottom of the conical end of the sintering silo 1. It is used to fix the sintering silo 1. By limiting the opening size of the protective groove, it can be ensured that the groove fits tightly with the bottom of the sintering silo 1, effectively fixing the sintering silo 1 in its position, and enhancing the stability and safety of the system. The tight fit of the protective groove can reduce the shaking or instability of the silo that may be caused by vibration during operation, thereby reducing the vibration impact on other components of the system and improving the reliability and durability of the system. By fixing the sintering silo 1, the wear and damage of the equipment that may be caused by the movement or shaking of the silo can be reduced, thereby reducing the maintenance and repair costs and extending the service life of the equipment. When in use, the driving motor 502 drives the vibrator, and the vibrator transmits kinetic energy to the vibration ring, which is driven in conjunction with the double-row backflush pipe 2. At the same time, the shock-absorbing spring and the connecting plate 501 dampen and support the sintering silo 1, and shake the material in the silo to prevent it from sticking to the inner wall of the silo.

[0025] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
