Abstract
The utility model discloses a vacuum pump installation structure of woodwork processing center. The vacuum pump installation structure comprises a vacuum pump and a whistle box, wherein the vacuum pump is located in the whistle box, a plurality of noise silencing chambers are arranged in the whistle box, the noise silencing chambers are mutually communicated, and gas generated on an air outlet ofthe vacuum pump can silence noise repeatedly among a plurality of noise silencing chambers, thereby effectively lowering exhaust noise of the vacuum pump and enabling operating staffs to work under quieter environment.
Description
Technical field
The utility model relates to a kind of wood working machine, particularly a kind of vacuum pump mounting structure of carpenter's machining center.
Background technique
The suction that existing wood working machine adopts vacuum pump to produce is mostly realized adsorbing plank, is absorbed functions such as wood chip, cooling, so vacuum pump has obtained using very widely in wood working machine.But there is the excessive shortcoming of exhaust noise in use in vacuum pump, and the operating personnel damages hearing easily as working under noisy environment for a long time on every side.
The model utility content
At above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model provides a kind of novel evacuated pump mounting structure, this structure can effectively be eliminated the noise that vacuum pump produces, and the operating personnel can relatively quietly be worked under the environment at one.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of vacuum pump mounting structure of carpenter's machining center, comprise a vacuum pump, described vacuum pump is provided with intake grill and exhaust outlet, described intake grill is connected with a filter, also comprise a Sound Attenuator, described Sound Attenuator base plate is provided with first dividing plate, leave the slit between the top of described first dividing plate and the described Sound Attenuator cover plate, described Sound Attenuator cover plate is provided with second partition, leave the slit between described second partition lower end and the described Sound Attenuator base plate, described Sound Attenuator inwall, first baffle surface, the second partition surface is equipped with sound absorbing material, form first anechoic chamber between described first dividing plate and the adjacent Sound Attenuator side plate, form second anechoic chamber between described first dividing plate and the second partition, form the 3rd anechoic chamber between described second partition and the adjacent Sound Attenuator side plate, described vacuum pump is fixed on described first anechoic chamber's base plate, the exhaust outlet of described vacuum pump is facing to described first dividing plate, also be provided with an attachment hole on the described Sound Attenuator side plate, described attachment hole position is corresponding with described filter intake grill position.
Based on above-mentioned major technique feature, the right and left side plate of described Sound Attenuator is equipped with ventilated port, on the described ventilated port fan is housed.
Based on above-mentioned major technique feature, described vacuum pump is connected with frequency variator.
Technique scheme has following beneficial effect: the vacuum pump mounting structure that adopts carpenter's machining center of this structure, the gas that the vacuum pump exhaust outlet is got rid of at first enters in first anechoic chamber, enter second anechoic chamber by the slit between first dividing plate and the Sound Attenuator cover plate then, enter the 3rd anechoic chamber by the slit between second partition and the Sound Attenuator base plate again, be discharged to the Sound Attenuator outside then.Owing to be equipped with sound absorbing material on the surface of the inwall of Sound Attenuator and first dividing plate, second partition, the gas that the vacuum pump exhaust outlet produces can carry out noise reduction repeatedly between first anechoic chamber, second anechoic chamber and the 3rd anechoic chamber, thereby can effectively reduce the exhaust noise of vacuum pump, the operating personnel can quietly be worked under the environment at one.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view.
Fig. 2 is that the B-B of Fig. 1 is to sectional view.
Embodiment
Engaging accompanying drawing below is described in detail preferred embodiment of the present utility model.
The vacuum pump mounting structure of this carpenter's machining center comprises a vacuum pump 11 as shown in Figure 1, 2, the intake grill of vacuum pump 11 is connected with an end of a filter 12, the other end of filter 12 is connected with a suction pipe 15, and the exhaust outlet of vacuum pump 11 is connected with a baffler 13.This vacuum pump mounting structure also comprises a Sound Attenuator, the base plate 22 of Sound Attenuator is provided with first dividing plate 26, the cover plate 21 of Sound Attenuator is provided with between the top of second partition 25, the first dividing plates 26 and the cover plate 21 and is provided with the slit, is provided with the slit between the lower end of second partition 25 and the base plate 22.Form first anechoic chamber 31 between first dividing plate 26 and the Sound Attenuator side plate 23, form second anechoic chamber 32 between first dividing plate 26 and the second partition 25, form the 3rd anechoic chamber 33 between second partition 25 and the Sound Attenuator side plate 24, be equipped with sound absorbing material 27 on the surface of the inwall of Sound Attenuator and first dividing plate 26, second partition 25.Vacuum pump 11 is positioned at first anechoic chamber 31, and the exhaust outlet of baffler 13 also has an attachment hole facing to first dividing plate 26 on the Sound Attenuator side plate, and suction pipe 15 stretches out outside the Sound Attenuator by this attachment hole.
Adopt the vacuum pump mounting structure of this mode, the gas of being got rid of by the outlet of baffler 13 enters in first anechoic chamber 31 along the C direction, enter second anechoic chamber 32 by the slit between first dividing plate 26 and the Sound Attenuator cover plate 21 then, enter the 3rd anechoic chamber 33 by the slit between second partition 25 and the Sound Attenuator base plate 22 again, be discharged to the Sound Attenuator outside at last.Owing to be equipped with sound absorbing material 27 on the surface of the inwall of Sound Attenuator and first dividing plate 26, second partition 25, the gas that the vacuum pump exhaust outlet produces can carry out noise reduction repeatedly between first anechoic chamber 31, second anechoic chamber 32 and the 3rd anechoic chamber 33, thereby can effectively reduce the exhaust noise of vacuum pump, the operating personnel can quietly be worked under the environment at one.
Respectively be provided with two air outlet holes 41 on the Sound Attenuator sidewall 23,24, have fan 42 on the air outlet hole 41, the blowing direction of fan 42 is consistent with the air-out direction C direction of exhaust outlet.Can accelerate the velocity of discharge of gas in the Sound Attenuator by the blowing of fan 42, the gas that vacuum pump is produced is got rid of fast, avoids occurring in the Sound Attenuator the too high problem of temperature because ventilation is smooth.
More than the vacuum pump mounting structure of carpenter's machining center that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
