Description

TECHNICAL FIELD

[0001] The utility model relates to a field of unloading ash, specifically to an automatic double -deck unloading ash device. BACKGROUND

[0002] In the current steel industry, as a key material discharge equipment, the performance and stability of double -deck unloading ash valve directly affect the efficiency and safety of production line. After investigation, the mainstream double -deck unloading ash valve on the market, whether it is heavy hammer type or pneumatic type, generally adopts the plug valve as auxiliary component. However, there are a series of common defects in the cooperation of these double -deck unloading ash valves and plug valves, which seriously restricts its application effect.

[0003] Firstly, the plug valve mainly undertakes isolation and maintenance function in the double -deck unloading ash valve system, and does not participate in the daily unloading ash linkage. The plug valve includes a valve body, a plug and a fixed frame, the valve body is fixed at the bottom end of the silo, the fixed frame is located at one side of the bottom of the silo and connected with the valve body, the plug is slidably connected between the valve body and the fixed frame, and a driving assembly is arranged on the side of the fixed frame away from the valve body. The fixed frame is a frame structure, due to the structural limitation of the plug valve and the influence of the use frequency, after multiple opening and closing operations, air leakage phenomenon is prone to occur between the valve body and the plug. This air leakage not only reduces the unloading efficiency, but also may cause material leakage, and further causes environmental pollution problem.

[0004] Secondly, the upper valve flap of the double -deck unloading ash valve often faces the difficulty of closing with material when closing. That is, when the material is still flowing, the upper valve flap is forced to close, causing the material to directly impact the rubber sealing surface, causing damage to the sealing surface. Once the sealing surface is damaged, air leakage problem comes, which seriously affects the normal use of the unloading ash valve and the stability of the system.

[0005] In addition, the traditional double -deck unloading ash valve usually adopts time control to open and close the upper flap valve flap, to adjust the material quantity. However, due to the instability and unpredictability of material flow, this time control method is often difficult to accurately control the material quantity in the upper valve body. When the material is too much, the upper valve flap is easy to be stuck by the material, causing unsmooth unloading, and even affecting the normal operation of the whole production line. Therefore, this time control feeding method has great risk and instability. INVENTION CONTENTS

Figure 1 Even after multiple opening and closing operations, good sealing effect can be maintained, and the occurrence of air leakage is significantly reduced. Not only is the ash discharging efficiency improved, but also material leakage and environmental pollution problems are effectively avoided, the bottom of the plug valve and the double-layer ash discharging valve 1 are provided with a buffer silo 7, the buffer silo 7 is used for temporarily storing the material flowing out of the plug valve, which not only reduces the direct impact of the material on the double-layer ash discharging valve 1, but also improves the efficiency and stability of ash discharging, the total amount of the material is limited by the buffer silo 7, and the opening and closing of the upper valve flap is controlled at a fixed time, so that the closing operation is performed after the material flow stops, thereby avoiding the direct impact of the material on the rubber sealing surface, effectively prolonging the service life of the sealing surface and improving the stability and reliability of the double-layer ash discharging valve 1.

[0023] Further, the side of the buffer silo 7 away from the valve body 2 is an inclined surface, the inclined surface being located below the fixed frame 4, the inclined surface of the buffer silo 7 facilitating the flow and discharge of the material and reducing the accumulation and blockage of the material in the buffer silo 7, and when the material flows out between the plug plate 3 and the valve body 2, the inclined surface of the buffer silo 7 receives and downwardly guides the outflowing material.
