The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the chain type automatic turning dust collector of the present invention includes a frame 10, a main rotating motor 20, a driven wheel 30, a conveying net 40, filter cotton 50, a new cotton roll 60, an old cotton roll 70, a filtering device 80 and a pressure sensing control system 90.

The main rotating motor 20 and the filter unit 80 are fixed to the frame 10. The driven wheel 30, the new cotton roll 60 and the old cotton roll 70 are rotatably mounted on the frame 10, and the new cotton roll 60 and the old cotton roll 70 are located on two opposite sides of the filtering device 80. The conveying net 40 is sleeved on the main rotating motor 20 and the driven wheel 30. The two ends of the filter cotton 50 are respectively wound on the new cotton roll 60 and the old cotton roll 70. The filter cotton 50 is filled in the conveying net 40 as a filter layer to form a filter surface. The filter device 80 is provided with an air inlet 81, an air outlet 82, and an inspection door 83. The filtering surface is located in the filtering device 80 and between the air inlet 81 and the air outlet 82. The inspection door 83 is located between the air inlet 81 and the filtering surface. The pressure sensing control system 90 includes a differential pressure gauge, and the air inlet 81 and the air outlet 82 are respectively provided with a differential pressure gauge. The two sides of the filtering surface are also respectively provided with a differential pressure gauge.

The filter cotton 50 is made of glass fiber filter cotton and active carbon filter cotton.

The glass fiber filter cotton is made of glass fibers with different thicknesses and lengths through a special processing technology. The glass fiber has stable performance, high temperature resistance, high efficiency, large capacity and long service life, and is widely applied to primary filters, high temperature resistant filters and high efficiency filters of general ventilation systems, and places and environments with high requirements on air filtration. And only glass fibers are sufficient under certain special circumstances.

The activated carbon filter cotton refers to filter cotton which is obtained by subjecting synthetic fibers to carbon soaking and glue adding treatment, and is obtained by specially processing carbon raw materials, wherein the sources of the carbon raw materials are mostly taken from petroleum products, coal mines or wood raw materials. In the manufacturing process, the carbon raw material is crushed and then heated (activated) at a high temperature of 500-1800 DEG F (260-582 ℃) to generate large and small pores, and the large and small pores are called macropores and micropores. The size and distribution of the holes determine the strength of the pollutant removing capability of the carbon fiber. In the embodiment, the internal surface area of the honeycomb/granular carbon fiber can reach 400-1200 square meters per gram, namely, the surface area of a particle of yellow bean-like activated carbon can reach 360 plateaus, and the honeycomb/granular carbon fiber has strong adsorption efficiency.

The chain type automatic turnover dust remover also comprises a slag scraping plate, and the slag scraping plate is positioned above the filter cotton 50.

When the chain type automatic turnover dust remover is used, waste gas enters the filtering device 80 from the air inlet 81, and the waste gas is filtered by the filtering surface. Because the two sides of the filtering surface are respectively provided with the differential pressure meters, the differential pressure between the two differential pressure meters sets the fluctuation range. When the waste gas containing grease, dust and particles passes through the filter cotton 50, most of the grease, dust and particles in the waste gas are trapped on the filter cotton 50 and are repeatedly filtered and trapped, so that the trapped matters on the filter cotton 50 are more and more, the transmittance of the filter cotton 50 is smaller and smaller, and the pressure difference between two sides of the filter cotton 50 is more and more. When the pressure difference exceeds the set range, the alarm of the electric control system sounds, and meanwhile, a slag scraping plate in the device is started, and the trapped objects on the filter cotton 50 are scraped back and forth to restore normal work.

After the filter cotton 50 is used for a long time, impurities in the waste gas are slowly embedded into the inner gap of the filter material, when the alarm cannot be eliminated even though the residue is scraped repeatedly, and at the moment, when the differential pressure of the differential pressure gauge of the air inlet 81 and the air outlet 82 exceeds a set range, the alarm of the electric control system makes a sound, a driver of the device starts a rotating wheel, the rotating wheel is rotated to a set clamping position, the old filter cotton 50 is rolled out of a filter surface, and the new filter cotton 50 is pulled into a filter section for automatic replacement.

A current sensor is arranged at a control switch of a motor and is realized through a PLC (programmable logic controller) electric control system according to the output value of current, when the current of the motor is reduced to a certain value (the value can be adjusted), the filter cloth can be automatically updated, a capacitance type differential pressure transmitter is adopted for measuring the pressure difference △ P between the front and the back of a conveying net 40, the output signal of the transmitter is sent to a PLC input module to be set and compared in a programmable controller, when the pressure difference △ P is larger than the set value in an automatic state, the system automatically starts a filter cloth replacing motor to automatically replace the filter cloth, when the pressure difference △ P is larger than the set value in a manual state, the system automatically alarms, a silencer is arranged on an electric cabinet, the silencer can be silenced after a silencing key is arranged, and if the silencer.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the scope of the claims of the present invention.
