Description
Technical Field
The invention belongs to the technical field of dust suppression and noise reduction, and particularly relates to a stone sawing dust suppression and noise reduction device and method for a circular saw.
Background
The quarry stone sawing process is a necessary process for forming stone slabs, and a combined diamond disk saw is generally used for sawing marble quarry stones or granite quarry stones into rough slabs with certain widths. The combined type diamond circular saw main shaft is of a cantilever type structure, a plurality of circular saw blades can be hung to saw a stone raw material, although the processing efficiency is improved by the aid of the processing mode, a large amount of dust is diffused in the sawing process of the raw material, and air quality of a workshop environment is affected. A large amount of dust enters the human body after passing through the respiratory tract of a human body, and can directly invade the lung of the human body, so that a large amount of skin tissues in the human body are adhered, and the human body health is seriously damaged.
Meanwhile, high-frequency noise during sawing exceeds 120dB (A), the influence on the sound environment in a workshop is caused (the regulation in GBZ/T189-2007 is that the upper limit of noise is not higher than 85dB in a workplace which is in contact with noise for 8 hours during work), people who work for a long time under the noise of the workshop are easy to generate symptoms such as fatigue, ears with singing, stomach pain, gastric acid and other gastrointestinal disorders, memory deterioration and the like, the auditory organs of the workers in the workshop are also seriously damaged, and the longer the working time is, the greater the damage degree is in the aspects of losing high-pitch frequency hearing, damaging the auditory valleys, influencing normal conversation of the workers in the workshop and the like. In addition, the contraction and release of the blood vessels of persons who are under noise in the workshop for a long time are easily affected, thereby causing hypertension and seriously damaging the cardiovascular system of workshop staff.
At present the raw materials saw cuts and only carries out the workshop through the mode of waterwheel watering and presses down dirt, does not produce the source to the dust and handles, and the thinner dust that produces when saw cutting still diffuses in the workshop, generally wears modes such as earplug to the workman to noise pollution and protects, but the effect is not good.
Disclosure of Invention
Aiming at the defects, the invention provides a stone sawing dust suppression and noise reduction device and method for a circular saw, which solve the problems of overhigh dust concentration diffused inside and outside a workshop and overhigh sawing noise which are not beneficial to ensuring the health of workers under the condition of ensuring the normal sawing operation of the circular saw in the workshop. Install to the saw blade department through the protection casing with collection dirt mechanism, locate to collect the processing to the dust at the source that saw cuts the dust and produce, and then reduce and fill the dust concentration in saw cutting the workshop, improve workshop environmental quality, help protecting the staff, reduce the harm that the dust caused to people's healthy. Through installing the sound barrier at workshop inner wall and hanging a door mechanism in the feed inlet department installation in workshop, saw cut the noise that produces and by sound barrier and hanging a door mechanism separation when transmitting to the external world, help weakening saw cut the influence of noise to staff outside the workshop, guarantee that staff's is healthy.

In the prior art scenario, in order to facilitate the transportation of the raw material 23 into the workshop 2, the feed inlet 22 of the workshop 2 is in a completely open state without any shielding. The staff operates circular saw 1 through switch board 9 outside workshop 2 to cut waste material 23. The noise generated by sawing directly passes through the feed opening 22 and adversely affects the workers outside the workshop 2, and the dust generated by sawing also passes through the feed opening 22 and spreads outside the workshop 2, thus affecting the health of the workers outside the workshop 2. In order to reduce the influence of noise and dust on workers, a suspension door mechanism is arranged at the feed port 22 to increase the degree of sealing of the workshop 2 and reduce the influence of noise and dust on the outside workers. The influence of the sawing noise on workers outside the workshop 2 is reduced by mounting sound barriers 7 on the inner walls of the workshop 2.
