Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder heat exchanger equipment, in particular to a vibration-proof powder heat exchanger. Background Art
[0002] Because powders are different from conventional fluids or gases, they are easy to absorb moisture, have high viscosity, and have poor fluidity inside the heat exchanger. They are prone to accumulation on the heat exchange plate components inside the heat exchanger, which can lead to poor discharge and material jamming. Based on this, powder heat exchangers usually have vibrators that can vibrate continuously around the heat exchanger to shake the material.
[0003] However, since powder heat exchangers are usually equipped with a variety of other equipment (such as thermometers, pressure gauges, etc.), when the vibrator continues to vibrate the heat exchanger, these vibrations will cause damage to the instruments and equipment. For example, structural resonance will occur in the instruments and equipment and the internal pipes, affecting the detection of the instruments and equipment, shortening the service life of the instruments and equipment and the internal pipes of the heat exchanger, etc.
[0004] Moreover, the continuous vibration will generate vibration noise, which will become the radiation source of the space where the heat exchanger is located (such as an indoor workshop), further causing resonance of other objects, causing harm to the workers' body and mind, as well as the surrounding environment.
