Abstract

A mechanical pump sound-proof shield which belongs to the machinery equipment manufacturing field, is a box provided with holes, comprises a box board(1) composed of double-surfaced board (11)clamped with an sound panel(12); a cushion(3) fixed and connected with the bottom box board(1); a fan(5) opposite to an air vent(7)used for the wind intake and wind exhaust on the shield, and is fixed and provided with a mechanical pump(4)fixed on the cushion(3)through the bracket(6); a silencer plate(9) covered outside the air vent(7)and corresponding to the fan(5) is fixed with the box board(1); an air deflector(10) opened on the top connected with the silencer plate(9) outside the silencer plate and forms a hollow cavity with the silencer plate(9) is provided with a plurality of through-holes(8).The present utility model has the advantages of small size, obvious lowering noise, various vibration reducing effect.

Description

The mechanical pump sound-insulating cover
Technical field
The utility model belongs to machinery and makes the field, particularly vacuum equipment manufacturing field.
Background technique
Mechanical pump is the necessary air extractor of vacuum system, and traditional mechanical pump noise is big, vibrations are violent, and is incompatible with the environmental requirement of laboratory, semi-conducting material and device production department.The someone has developed special low noise, low vibrating machine pump for this reason, compares with traditional mechanical pump, and these low noises, low vibrating machine pump pumping efficiency descend, and price will go up about ten times.In order to carry out the noise reduction damping with lower cost to mechanical pump when keeping traditional mechanical pump work efficient, people adopt various measures that mechanical pump is carried out sound insulation and handle.Method commonly used at present is that interrupter-type is handled, and promptly whole vacuum system is closed with sound arrester, with the blocking-up noise.But it is bigger that sound arrester in the past not only takes up room, and noise reduction and damping effect are unsatisfactory, cause using scope to be restricted.
The model utility content
The purpose of this utility model is will provide that a kind of volume is little, good damping effect, assurance soundproof effect, do not reduce the totally-enclosed sound-insulating cover of mechanical pump of pumping efficiency simultaneously.
The utility model is a porose casing, it is characterized in that: it includes the beam affixed with the bottom boxboard, respectively with casing on be used for the vent of air intake and air-out relative, by support and the fan that is fixed on the mechanical pump Joint on the beam, cover on outer corresponding with fan and affixed with the boxboard baffler of vent, the boxboard of casing is made of the panel, acoustic board, the panel that stack gradually together.
Described baffler by with the acoustical panel that has a plurality of through holes of panel Joint, its upper shed, to cover on acoustical panel outer with acoustical panel is affixed and constitute the air guide sleeve formation of a cavity with it.
The utility model not only volume is less relatively, and can realize good noise and vibration dampening effect under the situation that does not reduce pumping efficiency.
Description of drawings
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the front view of acoustical panel 9;
Fig. 3 is the sectional drawing of boxboard 1.
Embodiment
See Fig. 1,2, boxboard 1 passes through the affixed formation casing of bolt with aluminum alloy frame 2, damping pad 3 is affixed with the boxboard 1 of bottom, mechanical pump 4 is positioned at damping pad 3 tops and affixed with it, be respectively applied for air intake and air-out, affixed by motor-driven fan 5 by support 6 and mechanical pump 4, be used for the centrifugal cutter of the fan 5 of air intake over against mechanical pump 4 motor rear ends, vent 7 on the box side is relative with fan 5, outside the vent 7 relative with fan 5, have with boxboard 1 and pass through the affixed baffler of bolt, baffler is by acoustical panel 9 that has a plurality of through holes 8 and top edge opening, it is outer affixed and constitute air guide sleeve 10 formations of a cavity with it with the former to be buckled in the former, top boxboard 1 has affixed with it handle 13, and the exhaust tube 14 of mechanical pump 4 is stretched toward the casing outside by the hole on the boxboard 1.
See Fig. 3, boxboard 1 constitutes by stacking gradually acoustic board 12, the panel 11 that together panel 11, sound absorbing material make.The material of panel 11 can use wood, plastic board or sheet metal.The material of air guide sleeve 10 can be sound absorbing materials such as wood or foamed plastics.
When mechanical pump 4 work, noise is by boxboard 1 blocking of three-decker, air-flow circulates by intake grill and exhaust port under the effect of fan 5, the casing internal air pressure is not increased because of mechanical pump 4 exhausts, thereby the pumping efficiency that has guaranteed mechanical pump 4 does not reduce, simultaneously, after air communication is crossed through hole 8 rectifications of acoustical panel 9, further reduce the noise that air-flow produces through air guide sleeve 10; The vibrations that mechanical pump 4 and fan 5 produce discharge by damping pad 3, reach effectiveness in vibration suppression.

Claims (2)
