Description

Technical Field

[0001] The utility model relates to a noise elimination and reduction device, in particular to a green and environment-friendly noise elimination and reduction device for high-pressure air exhaust of a filter press. Background Art

[0002] The high-efficiency slime filter press is an intermittent pressure filtration device, mainly used for the solid-liquid separation of various suspensions. It relies on the pressing device to press the filter plates tightly, then pumps the suspension into the filter chamber, and separates the solid particles and liquid materials through the filter cloth. The basic filtration process includes pressing the filter plates, feeding, squeezing, back blowing, high-pressure unloading, loosening the filter plates, pulling the plates, and discharging. Among them, the squeezing process of the filter press is to squeeze the filter cake by pressing high-pressure gas into the diaphragm plate, so as to further reduce the moisture remaining in the filter cake and discharge the filtrate outside the machine. This process lasts for 20S. After 20S, the high-pressure gas starts to unload, that is, the high-pressure gas in the diaphragm plate is emptied. The emptying process is to discharge all the high-pressure gas with a pressure of 0.6 - 0.8MPa and a volume of 5 - 8 in a short time (to reduce the exhaust noise, the exhaust valve is closed slightly to reduce the exhaust volume, and the exhaust time is about 30S). Due to the short time, large gas pressure and large volume, the emptying process will generate deafening and unbearable noise, which will damage the hearing, stimulate the nervous system, and affect all organs of the body in the long term, bringing harm to the human body.

The upper and lower ends of the vertical partition plate are respectively fixed outside the upper horizontal partition plate and in the middle of the lower horizontal partition plate. The diversion holes are distributed on the horizontal partition plates and the vertical partition plate. The reflux plate is fixed radially on the inner side end of the silencing cylinder and is distributed between the horizontal partition plates.

[0013] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] As Figures 1 to 4As shown in the figure, a noise reduction device for the high-pressure air exhaust of a green and environment-friendly filter press includes a silencing cylinder 1, a flange 2, an air inlet channel 3, a transverse partition 4, a vertical partition 5, a diversion hole 6, a reflux plate 7, a cover plate 8, a stainless steel mesh 9, an exhaust hole 10, and a shockproof bracket 11. The bottom end of the silencing cylinder 1 is connected to the flange 2. The air inlet channel 3 is axially communicated with the silencing cylinder 1 through the middle of the flange 2. The transverse partitions 4 are alternately fixed radially at the inner end of the silencing cylinder 1 from left to right. The upper and lower ends of the vertical partition 5 are respectively fixed to the outside of the upper transverse partition 4 and the middle of the lower transverse partition 4. The diversion holes 6 are distributed on the transverse partitions 4 and the vertical partition 5. The reflux plate 7 is radially fixed to the inner end of the silencing cylinder 1 and is distributed between the transverse partitions 4. The cover plate 8 seals the top end of the silencing cylinder 1. The stainless steel mesh 9 is fixed to the bottom end of the cover plate 8. The exhaust holes 10 are distributed at the top of the side end of the cover plate 8 and the silencing cylinder 1, and the exhaust holes 10 correspond to the stainless steel mesh 9. The shockproof bracket 11 is installed on the side end of the silencing cylinder 1.

[0015] The shockproof bracket 11 includes a fixed cylinder 12, shock-absorbing cotton 13, a bracket 14, and a fixed base 15. The inner end of the fixed cylinder 12 is fixed with the shock-absorbing cotton 13, and the fixed cylinder 12 is sleeved on the side end of the silencing cylinder 1 through the shock-absorbing cotton 13. The bracket 14 is fixed to the side end of the fixed cylinder 12. The fixed base 15 is fixed to the bottom end of the bracket 14.

[0016] When the silencing cylinder 1 vibrates, it is transmitted to the shock-absorbing cotton 13 supported by the fixed cylinder 12.

[0017] The working principle of the present utility model: The exhaust valve of the high-efficiency slime filter press fixes the silencing cylinder 1 through the flange 2. The silencing cylinder 1 forms a support with the ground through the shockproof bracket 11. When high-pressure gas enters the interior of the silencing cylinder 1 through the air inlet channel 3, the gas is divided through the diversion holes 6 among the channels formed by the transverse partitions 4 and the vertical partition 5, and the reflux gas formed by the cooperation of the reflux plate impacts, overlaps, interferes with, and cancels each other, reducing the impact force. The divided gas finally passes through the stainless steel mesh 9 and is discharged through the exhaust holes 10. At the same time, the vibration transmitted by the gas in the silencing cylinder 1 is absorbed by the shock-absorbing cotton 13 made of the fixed cylinder 12. The exhaust noise of the high-efficiency slime filter press is reduced, and the production efficiency is improved.

[0018] The above is the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principle and spirit of the present utility model, the changes, modifications, substitutions, and variations made to the implementation manners still fall within the protection scope of the present utility model.
