Description

Technical Field

[0001] This utility model relates to the technical field of cement production, and in particular to an energy-saving and environmentally friendly grate cooler capable of recovering hot air. Background Technology

[0002] Cement production is the process of processing raw materials such as limestone and clay through a series of processes to finally produce cement. The grate cooler is an important main equipment in the clinker calcination system of a cement plant. Its main function is to cool and transport cement clinker, and at the same time provide hot air for rotary kilns and decomposition furnaces. It is the main equipment for heat recovery in the calcination system. The grate cooler is often needed in the process of cooling and transporting cement clinker.

[0003] Currently, traditional grate coolers introduce hot air into the rotary kiln through the grate cooler body for secondary use. This results in low heat recovery efficiency and affects system ventilation, which not only increases equipment maintenance costs but also easily leads to a decrease in cement clinker output and quality. Utility Model Content

[0004] Therefore, one objective of this utility model is to propose an energy-saving and environmentally friendly grate cooler that can recover hot air. The hot air is transmitted to a waste heat boiler through pipelines, thereby recovering the hot air in the grate cooler. This not only allows for the recycling of hot air but also saves energy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and environmentally friendly grate cooler capable of recovering hot air, comprising a grate cooler body, a pipe connected to one side of the grate cooler body, a sealing ring fitted on the outer side of the pipe, a filter plate fixed on the inner side of the pipe, a clamp fixed on the outer side of the pipe, a temperature control valve installed on the inner side of the clamp, a temperature alarm installed on the outer side of the pipe, a waste heat boiler connected to one end of the pipe, and a fixing frame installed below the pipe.

[0006] Preferably, the temperature control valve is fixedly connected to the pipeline by a clamp, and a sealing ring is fitted on the outer side of the grate cooler body.

[0007] Preferably, two sets of fixing frames are provided, and a pipe is fixed on the other side of the grate cooler.

[0008] Preferably, a temperature control valve and a waste heat boiler are fixedly connected to the two ends of the pipe, respectively, and the waste heat boiler is fixedly connected to the grate cooler body through the pipe.

[0009] Preferably, a temperature control valve and a grate cooler body are fixedly connected to the two ends of the pipe, respectively, and the pipe and the temperature control valve are fixed to the inside of the clamp.

[0010] Preferably, two sets of clamps are provided, and a temperature alarm is provided on the other side of the pipe.

[0011] Preferably, the pipeline is provided in two sets.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This energy-saving and environmentally friendly grate cooler can recover hot air. The pipeline can transport the hot air in the grate cooler body to the waste heat boiler for recycling. The sealing ring can increase the sealing between the pipeline and the grate cooler body. The filter plate can effectively reduce impurities in the pipeline, protect the waste heat boiler, and thus extend its service life. The temperature control valve can detect the temperature of the pipeline. When the detected temperature is too high, the flow rate can be adjusted by adjusting the valve opening to ensure that the pipeline temperature is maintained at a normal level. When the pipeline temperature is very high, a temperature alarm will be triggered to remind the staff, thereby protecting the safety of equipment and personnel. Finally, the waste heat boiler can convert the waste heat in the grate cooler body into heat energy for equipment heating, thereby reducing energy consumption. Attached Figure Description
