Abstract
The utility model relates to a pressure filter auxiliary device for the gaseous amortization of pressure filter unloading is fallen and is fallen the noise, specifically is the pressure filter device of falling and falls. The problem of the big and filter plate filter cloth in case the damage lacks the protection of pressure filter atmospheric noise is solved. The filter press noise reduction device comprises a box body and a silencer, wherein a mounting plate is vertically fixed on an input pipe of the silencer, a mounting hole is formed in the top of the box body, the mounting plate covers the mounting hole and is fixed with the top of the box body through a bolt, the silencer is fixed to the top of the box body, one end of the silencer, located in the box body, of the silencer input pipe is located outside the box body, and exhaust holes are formed in the side wall of the lower portion of the box body. The utility model discloses not only realize that the gaseous noise of pressure filter unloading is eliminated, in case damaged at the filter plate filter cloth of pressure filter moreover, play the guard action to the material along with the discharge in the lump to prevent to pollute the operation space, can discern through the exhaust hole again convenient and fast whether the filter plate filter cloth appears damaged.
Description
Technical Field
The utility model relates to a pressure filter auxiliary device for the gaseous amortization of pressure filter unloading is fallen and is fallen the noise, specifically is the pressure filter device of falling and falls.
Background
The quick-opening filter press is intermittent dewatering equipment, and the working process of the quick-opening filter press comprises the main links of oil cylinder pressing, feeding, squeezing, emptying, back flushing, oil cylinder loosening and pulling plate discharging. Wherein, the working medium of the squeezing link is compressed air which is supplied by an air compressor. When the diaphragm plate works, compressed air continuously enters the inside of the diaphragm plate, and the pressure reaches about 1 Mpa. After the link is finished, the squeezed gas stored in the partition plate instantly gushes out in the emptying stage, namely, the pressure container (with the volume about 3-5 m for heavy year and even larger) is vented, the noise volume is large, the duration is long, and the physical and mental health of post operators is harmed. Meanwhile, once the filter cloth of the filter plate is damaged in the using process, the air can be discharged to pollute, materials are discharged to an operation space along with the air, the problem of messy and poor production environment is caused, the cleaning pressure of field operation personnel is increased, and the occupational hazard risk is increased.
Disclosure of Invention
The utility model provides a big and the filter plate filter cloth of pressure filter unloading gas noise in case the damaged problem that lacks the protection provides a device of making an uproar falls in pressure filter.
The utility model discloses an adopt following technical scheme to realize: device of making an uproar falls in pressure filter, including box and (purchase outward) muffler, the vertical fixation has the mounting panel on the input tube of muffler, and open at the box top has the mounting hole, and the mounting panel covers on the mounting hole and fixes with the box top with the bolt to make the muffler be fixed in the box top and make the amortization one end of muffler be located the box, outside the mouth of pipe of muffler input tube was located the box, it has the exhaust hole to open on the lateral wall of box lower part. When the pressure filter is used, the emptying gas discharge port of the pressure filter is connected with the pipe orifice of the input pipe of the silencer through a pipeline, when the pressure filter operates to the emptying link in the working state, high-pressure gas enters the box body to realize primary silencing through the silencer, secondary dilatation silencing is realized through the box body expansion, and the high-pressure gas is discharged through the exhaust hole at the lower part of the box body. Thus, after twice silencing, the recognizable noise is extremely limited, and basically no influence is caused to post operators. Meanwhile, once the filter plate and the filter cloth of the filter press are damaged, the box body plays a role in protecting materials discharged along with the air-release gas, and the operation space is prevented from being polluted. Whether the filter plate and the filter cloth are damaged or not can be effectively judged by observing whether the material is discharged from the exhaust hole or not, so that the related maintenance activities can be timely and accurate.
The utility model discloses filled non-pressure filter silencing device's blank, its structural design is reasonable, accords with the maintenance requirement when wasing and dismantling, not only realizes that the gaseous noise of pressure filter unloading is eliminated, in case damaged at the filter plate filter cloth of pressure filter moreover, plays the guard action to the material along with the gaseous discharge in the lump of unloading to prevent to pollute the operation space, can discern through the exhaust hole again convenient and fast whether the filter plate filter cloth is damaged appearing simultaneously.
