Description

Technical Field

[0001] The utility model relates to the field of cement production equipment, in particular to a raw material mill cyclone with an ash discharge mechanism. Background Art

[0002] The raw mill cyclone inlet flat section has serious dust accumulation, with a thickness of 0.6-1.5 meters and a weight of about 20 tons. The pressure difference between the inlet and outlet is 1200-1400 Pa, which poses a safety hazard. In order to solve the dust accumulation problem at the raw mill cyclone inlet flat section in the existing technology, personnel are usually organized to perform manual cleaning during shutdown. After many manual dust cleaning operations, it is found that this method is not only time-consuming and labor-intensive, but also that more dust will reappear in a short time after cleaning, and the effect is not good. Therefore, in order to solve the above problems, it is necessary to improve the existing raw mill cyclone structure. Utility Model Content

[0003] The purpose of the utility model is to provide a raw mill cyclone with an ash discharge mechanism to solve the problem of serious ash accumulation in the inlet flat section of the existing raw mill cyclone.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A raw mill cyclone with an ash discharge mechanism comprises a raw mill cyclone, wherein ash hoppers are evenly arranged at the bottom of the flat inlet section of the raw mill cyclone, the discharge port of the ash hopper is connected to a rotary discharger through an ash discharge chute, and the discharge port of the rotary discharger is connected to a chute.

[0006] An ash hopper is set at the bottom of the flat section of the raw mill cyclone inlet. In this way, the ash that would originally accumulate at the bottom of the raw mill cyclone inlet will flow into the ash discharge chute along the ash hopper, and then enter the chute through the rotary discharger, which effectively solves the problem of serious ash accumulation in the flat section of the raw mill cyclone inlet.

[0007] As a further preference of the present invention, there are four ash hoppers, which are respectively connected to four ash discharge chutes, and there are two rotary dischargers, which are grouped into two and are respectively connected to two rotary dischargers.

[0008] This can disperse the ash discharge and prevent too much ash from entering the same ash discharge chute and causing blockage problems.

[0009] As a further preference of the present invention, a material level switch is provided at the rotary feeder.

[0010] The material level switch is interlocked with the rotary feeder to automatically start and stop. After the material level switch receives the signal, the rotary feeder will run for 2 minutes to prevent air leakage in the rotary feeder.

[0011] As a further preferred embodiment of the present invention, a material guiding transition slope is provided at the connection between the ash hopper and the bottom of the flat section of the raw mill cyclone inlet.

[0012] In this way, when the ash falls around the ash hopper inlet, it will enter the ash hopper along the material guide transition slope, which can further solve the ash accumulation problem.

[0013] As a further preferred embodiment of the present invention, air outlet nozzles are evenly arranged on the top of the ash discharge chute, and the air outlets of the air outlet nozzles are arranged obliquely downward along the ash discharge direction.

[0014] The air outlet nozzle installed on the top of the ash chute can blow air to the bottom plate of the ash chute at regular intervals to prevent the ash chute from being blocked due to excessive slope and excessive ash.

[0015] As a further preferred embodiment of the present invention, a middle support rod is evenly provided in the middle of the ash discharge chute, and the middle support rod is correspondingly arranged to the air outlet nozzle.

[0016] When the gas comes into contact with the bottom plate of the ash chute during blowing, the ash chute will shake, which will affect the air tightness of the connection between the equipment and also affect the service life. In order to reduce the impact of this shaking, a middle support rod is set up to better support the ash chute and maintain its stability.

[0017] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0018] 1. An ash hopper is set at the bottom of the flat section of the raw mill cyclone inlet. In this way, the ash that would originally accumulate at the bottom of the raw mill cyclone inlet flat section will flow into the ash discharge chute along the ash hopper, and then enter the chute through the rotary discharger, which effectively solves the problem of serious ash accumulation in the raw mill cyclone inlet flat section.

[0019] 2. Disperse ash discharge to prevent excessive ash from entering the same ash chute and causing blockage.

[0020] 3. The air outlet nozzle installed on the top of the ash chute can blow air to the bottom plate of the ash chute at regular intervals to prevent the ash chute from being blocked due to excessive slope and excessive ash.

[0021] 4. When the gas contacts the bottom plate of the ash chute during blowing, the ash chute will shake, which will affect the air tightness of the connection between the equipment and also affect the service life. In order to reduce the impact of this shaking, a middle support rod is set up to better support the ash chute and maintain its stability. BRIEF DESCRIPTION OF THE DRAWINGS
