Description
Technical Field
The utility model relates to a mechanical equipment cooling device field specifically is a cold quick-witted equal wind device of comb.
Background
The important link in cement production is two-grinding and one-burning. The primary burning refers to the burning of clinker, and the clinker needs to be cooled after being burnt. In the production process, the clinker temperature is high and reaches 1250 ℃, air for each fan needs to be adjusted after entering the grate cooler, and the air using amount for pressure is different from that for different air chambers, so that the air using amount is required to be adjusted and controlled, and the aim of effectively cooling the clinker is fulfilled.
At present, most of air for cooling and controlling clinker is based on the principle that a fixed air duct of a fan is utilized, the air volume and the pressure are adjusted through frequency conversion or a valve, but the air for different air-inflating beams in the same air duct cannot be effectively controlled, the uneven air pressure and the air volume cannot reach the pressure of different air-inflating beams to be quickly and effectively adjusted, so that the problem that a grate bed material layer in a key process link in the production process is blown through or cannot be blown through is caused, the clinker cooling effect is poor, the temperature of secondary air is unstable and fluctuates greatly, and the normal calcination of a kiln is influenced.
The air draft main pipe of the traditional air equalizing device is generally positioned at one side, the upper part or the middle part of the air equalizing box body, each branch air inlet pipe is positioned at the middle part of the air equalizing device, and dust at the bottom of the air equalizing device is easy to accumulate to influence ventilation. In the air inlet pipeline, dust runs at a high speed, the air speed is rapidly reduced when the dust reaches the air equalizing box body, most of coarse-medium-fine dust and ultrafine dust with a large specific gravity can rapidly settle under the action of gravity and gather at the bottom of the air equalizing device and further accumulate upwards, the limited space of the air equalizing box body is occupied, the air equalizing box body cannot normally work, and therefore dust is required to be frequently cleaned or discharged.
Therefore, an air equalizing device capable of adjusting air pressure and preventing dust deposition and good ventilation is needed to supply air to different air charging beams of an air chamber so as to achieve the purpose of quickly cooling clinker and recovering waste heat.
SUMMERY OF THE UTILITY MODEL

The project starts from the existing practical production flow, and ventilation pipelines are independently arranged through different air-filled beam air pipes of air chambers. Aiming at the problems that the existing air pipes have dust accumulation, the operation stability of the device is influenced and the ash removal is inconvenient, the air equalizing device is designed and comprises a main air pipe, air distributing pipes and air collecting boxes, the main air pipe is connected to the air collecting boxes through the air distributing pipes, the air collecting boxes are arranged in air chambers, an inlet is connected with the air distributing pipes, an outlet is connected with an air inlet of an air charging beam of a grate cooler, the air charging beam of the grate cooler is arranged below, and a valve and a pressure gauge are arranged in an air distributing pipeline.
The main air pipeline and the air distribution pipeline are connected through flanges quickly to form a three-way structure, and the diameter of the main air pipe is larger than that of the air distribution pipe. The pressure of cooling air can be effectively ensured to be adjusted through the pressure gauge arranged on each air distribution pipeline to adjust and control the valve on the air distribution pipeline, air adjustment for different air filling beams is rapidly carried out, and clinker is rapidly cooled without blowing through.
The side surface of the air gathering box is provided with a 400-400 mm inspection door, the internal accumulated material condition can be quickly inspected, the lower bottom of the air gathering box is provided with a material cleaning hole, and the internal accumulated dust can be quickly discharged.
The main air pipe and the air distribution pipe are square pipelines, the diameter of the main air pipe is 400mm, and the diameter of the air distribution pipeline is 280 mm.
