Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a cement clinker rapid cooling device. Background Art

[0002] The main function of the clinker cooler is to provide an appropriate clinker cooling rate to improve the quality of cement and the grindability of clinker. After the clinker is rapidly cooled, it does not have time to complete crystallization, and part of it is in a glass phase. Even if the other part crystallizes, the grains are finer than those obtained by ordinary cooling rates. This kind of clinker can be made into cement with a higher grade. At the same time, thermal stress and cracks will be generated in the particles of the clinker after rapid cooling, making it easier to grind.

[0003] Grate cooler is an important main equipment in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker. At the same time, it provides hot air for rotary kiln and decomposition furnace, and is the main equipment for heat recovery in the burning system.

[0004] At the feeding end of the grate cooler, due to the influence of factors such as the gravity of the material and the rapid change of the temperature of the material, the material is easily accumulated at the feeding end of the grate cooler. If it is not handled in time, it will easily cause blockage, and the kiln will be shut down for treatment, causing economic losses.

[0005] For this reason, we propose a cement clinker rapid cooling device to solve the existing problems. Utility Model Content

[0006] The utility model aims to provide a cement clinker rapid cooling device in view of the problems existing in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cement clinker rapid cooling device, comprising a machine body, a discharge hopper, a feed port, a microporous plate and a movable plate, wherein a microporous plate is fixed at the lower end of the interior of the machine body, and the upper surface of the microporous plate is designed as a downward inclined slope, and a movable plate is elastically mounted on the upper surface of the microporous plate, and a vibration motor is fixed on the movable plate.

[0008] Preferably, a feed inlet is provided at the upper end of one side of the machine body, and an air inlet is provided at the lower end of the same side of the machine body;

[0009] A chamber is formed between the microporous plate and the body, and the air inlet is connected to the chamber;

[0010] The upper surface of the machine body is provided with various air outlets, and a filter plate is fixed to the bottom opening of the air outlet by bolts.

[0011] Preferably, springs are respectively installed on the movable plate by bolts, and each of the springs is respectively fixed to the microporous plate and the body by bolts;

[0012] The movable plate is located below the feed port, and the movable plate also has a microporous structure.

[0013] Preferably, a discharge hopper is installed at the end surface of the machine body;

[0014] The discharging hopper is connected to the machine body, and a discharging port is provided at the bottom end of the discharging hopper.

[0015] Preferably, a leg is installed on the lower surface of the body, and a cushion is glued to the lower surface of the leg;

[0016] There are four supporting legs in total, and the positions of the four supporting legs are distributed in a rectangular array on the lower surface of the body.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] During the use of the cement clinker rapid cooling device of the utility model, the cement clinker to be cooled is introduced into the machine body through the feed port, and at this time, the external cold air source is connected through the air inlet, and the cold air enters the lower part of the machine body through the microporous plate and enters the upper part of the machine body. The cold air enters the cement clinker on the microporous plate, forming a state in which the cement clinker particles and the cold air are completely mixed, which is called a fluidized state. In the fluidized state, the cement clinker is fully in contact with the cold air, thereby cooling the cement clinker;

[0019] The wind that has undergone heat exchange carries the heat and is discharged through the exhaust port into the external recovery pipeline. The hot air is used as combustion air to reduce the fuel consumption of the firing system, thereby recycling the heat.

[0020] The cooled cement clinker enters the discharge hopper under the action of the slope of the microporous plate and is finally discharged through the discharge port;

[0021] When cement clinker enters the machine body, most of the cement clinker falls onto the movable plate. At this time, the vibration motor drives the movable plate to vibrate. Under the vibration action and the blowing action of wind, the material can be prevented from accumulating at the feeding end of the grate cooler.

[0022] The utility model can quickly cool cement clinker in a fluidized state and prevent materials from being accumulated at the feeding end of the grate cooler, thereby preventing the grate cooler from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS
