Abstract
The utility model provides a defrosting mechanism used for an evaporator, comprising an evaporator coil and a frame fixedly arranged with the coil. A guide rod is respectively and fixedly arranged at four side angles of the evaporator which are parallel with the coil. A frost-shaving plate punctures and is vertically arranged on the guide rods and the coil. A threaded shaft is vertically and fixedly connected at the center of the frost-shaving plate. A nut provided with wheel teeth on a circle is arranged on the threaded shaft. A gear meshed with the wheel teeth of the nut is arranged on the output shaft of a motor, the motor is arranged on a machine frame which is fixedly connected with the frame. A nut position-limiting lifting-wheel is arranged on the machine frame corresponding to the gear. The utility model adopts the shaving plate mechanism to remove frost to satisfy a system work-condition requirement of preserving constant refrigeration and to enhance the work stability and efficiency of the system. Meanwhile, the utility model is characterized in that the defrosting effect is better; configuration and use cost is low; the automatic defrosting control requirement can be easily realized.
Description
Technical field
The utility model relates to the evaporimeter of refrigeration plant, is specifically related to a kind of Cryogenic air evaporimeter machinery defrosting structure.
Background technology
Be applied to freezer, technology is lower than 0 ℃ evaporimeter with leaving air temps such as cold airs, can when the frost layer reaches certain thickness, will have a strong impact on the heat exchange efficiency of evaporimeter in the surperficial frosting of coil pipe in the process of operation.Removing evaporimeter frosting at present generally is the method that adopts electrical heating, hot fluorine, hot ammonia and water spray, when carrying out defrost, need system to stop refrigerating operaton, thereby make by controlling temperature and produce fluctuation, the job stability of reduction system and operating efficiency, and when application scenario and technological requirement do not allow to be interrupted refrigeration, can only increase stand-by equipment, cause the system equipment investment to increase.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of system under uninterrupted refrigerating operaton operating mode, effectively removes the evaporimeter machinery defrosting structure of frosting.
The technical scheme that realizes above-mentioned purpose is: a kind of evaporimeter machinery defrosting structure, the framework that it includes evaporator coil and fixedly installs with coil pipe, four edges that are parallel to evaporimeter with coil pipe are set with guide post respectively, vertically be threaded onto and scrape white plate on guide post and the coil pipe, in the center of scraping white plate with scrape vertical linking to each other of white plate and be connected to leading screw, on its leading screw, be equipped with the nut of all belt wheel teeth of dish, be meshed with the gear teeth on the nut and be provided with the gear that is fixedly installed on the motor output shaft, on the frame that its motor is fixed in framework links to each other, the corresponding spacing top of the nut wheel that is provided with on frame with gear.
The utlity model has following advantage:
1, adopts the defrosting of scraper plate machinery, can satisfy the uninterrupted cooling condition requirement of system, improve the job stability and the operating efficiency of system.
2, by the operation of relay control setup time motor, be easy to realize automatic defrosting by designing requirement, can effectively improve the operating efficiency of evaporimeter.
3, simple in structure, energy savings, configuration and use cost are low, and defrosting effect is good.
