Dust remover, asphalt station and control method of asphalt station

Abstract

The invention provides a dust remover, an asphalt station and a control method of the asphalt station. The dust remover comprises: a dust removal box; an air inlet duct, which is communicated with thedust removal box; a valve body, which is arranged in the air inlet duct and used for opening or closing the air inlet duct; a temperature detection device, which is arranged in the air inlet duct andused for detecting the inner temperature of the air inlet duct; and a controller, which is electrically connected with the valve body and the temperature detection device and is used for controllingthe opening or closing of the valve body according to a detection result of the temperature detection device. According to the dust remover provided by the invention, the controller can control the opening or closing of the valve body according to the inner temperature of the air inlet duct detected by the temperature detection device so as to ensure that the temperature of gas entering the dust removal box is within a preset range and to prevent a cloth bag or the dust remover from being burnt due to too high temperature; cooling effect on the interior of the dust remover is stable and reliable, auxiliary tools do not need to be additionally arranged, and human intervention is not needed; and in addition, such a structure also avoids cost increase caused by adding an air inlet valve on the dust remover.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a dust collector, an asphalt plant and a control method for the asphalt plant. Background technique [0002] At present, the dust collectors in the asphalt station use cold air valves or bypass valves to realize the entry of cold air, thereby reducing the temperature of the exhaust gas and preventing the burning of the bag and dust collectors. However, the disadvantages of this method are as follows: 1. It is necessary to add a special air inlet valve structure; 2. The high-temperature exhaust gas does not completely stop entering the dust collector or fan. If it is human negligence and timely measures are not taken, it will cause serious impact; 3. Cold air valve The amount of cold air entering is limited, and its cooling effect is limited after the exhaust gas temperature exceeds 200 degrees Celsius. Contents of the invention [0003] The present invention aims...
