Warehouse bottom material-flushing resisting method and control device

Abstract

The invention relates to a method for preventing material from being scoured at reservoir bottom and a control device thereof. The method is that: the device for preventing material from being scoured at reservoir bottom is arranged at the blanking end of an electromagnetic vibrating machine; two sides of a connecting rod are provided with baffles of a baffle A and a baffle B, the baffle A is positioned at the blanking end of the electromagnetic vibrating machine and the baffle B is arranged on a material weighing scale and is overweighed than the baffle A. Gaps are positioned between the baffle A, the baffle B and the electromagnetic vibrating machine and the material weighing scale, powder materials can be evenly spilled on the material weighing scale through the gaps when blanking; when scouring material, the force is acted on the baffle B to lead the baffle B to be uplifted and the baffle A falls off due to the function of the connecting rod, thus preventing materials from being continued to flood; with the disappearance of scouring status, the baffle B falls down and the baffle A is uplifted due to the function of the connecting rod, therefore, the materials can flood and blank normally. The invention has the advantages of simple structure, reliable operation, high testing precision, high production efficiency, realizing manual monitoring, reducing labor intensity of workers, protecting the health of workers, guaranteeing stable production process, reducing the cleaning time of material scouring at reservoir bottom, improving follow-up working output, maintaining ratio and increasing chemical qualified rate of raw materials.

Description

technical field [0001] The invention relates to a storage bottom anti-scouring material method and a control device in the cement production process. The invention belongs to the technical field of cement building materials. Background technique [0002] In the cement production process, the batching accuracy of materials must be accurate, so when using powder batching, it is necessary to use a warehouse to store powdery materials. The general storehouse is a cylindrical structure, and a feed opening is opened at the bottom of the storehouse. An electric vibrator is equipped under the feeding port, and the material is fed at a uniform speed through vibration; a weighing scale is equipped under the electric vibrating machine, which is used to measure the weight of the material to make the ingredients accurate; the weighing scale is equipped with a conveying equipment, in the transportation of materials. When using powder materials, due to the certain fluidity of the powder...

Problems solved by technology

[0003] However, some materials have relatively strong powder fluidity, especially the high temperature in the storage warehouse is difficult to dissipate, making the powder extremely dry. When the material is discharged through the discharge port, it is easy to cause rushing, and a large amount of powder gushes out, causing equipment damage. Unable to operate and stop production; the bottom of the warehouse is full of dust, which affects the working environment, increases the work intensity of workers, and damages the health of workers; causes economic losses
