Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal equipment, in particular to pulse bag dust removal equipment capable of silencing. Background Art

[0002] The pulse bag dust collector is a dust removal device used to filter dust in the air. When the pulse bag dust collector is in use, it will suck the dust-containing air through the vacuum pump, and let the dust-containing air enter the dust filter space and be adsorbed by the dust filter bag to obtain filtered air. Secondly, the pulse bag dust removal equipment can also back-blow the dust filter bag with dust attached on the surface, so that the dust filter bag can be shaken and cleaned due to the impact of the airflow.

[0003] In the existing pulse bag dust removal equipment, the vacuum pump sucks the dust-containing air and allows the dust-containing air to enter the dust filter space so that the dust is filtered by the dust bag. The filtered air will be discharged to the outside after entering the suction pump. However, when the filtered air enters the suction pump, it will hit the inner wall of the space inside the suction pump due to the excessively fast flow rate, causing the suction pump to make noise and abnormal sounds, thereby causing the staff to be affected by the noise and abnormal sounds and unable to work normally.

[0029] refer to Figures 1 to 8 A silencing pulse bag dust removal device according to a preferred embodiment of the utility model will be described in detail below, wherein the silencing pulse bag dust removal device includes a device body 10, an air distribution component 20 and an air extraction component 30.

[0030] Specifically, the device body 10 includes a dust filter box 11 and a closed mounting plate 12. The dust filter box 11 forms an air intake space 102 and an air inlet 101 connected to the air intake space 102. The air containing dust is introduced into the air intake space 102 through the air inlet 101. The device body 10 also forms a dust filter space 103 connected to the air intake space 102. The closed mounting plate 12 is arranged on the inner wall of the dust filter space 103 to close the dust filter space 103. The closed mounting plate 12 forms a plurality of mounting through holes 1201.

[0031] The gas separation component 20 includes a plurality of gas separation components 21. The gas separation component 20 includes a plurality of gas separation components 21. The gas separation component 21 includes an air separation pipe 211 and a plurality of dust filter pipes 212. The plurality of dust filter pipes 212 are arranged on the air separation pipe 211, and the channel formed by the air separation pipe 211 is connected to the channel formed by the dust filter pipe 212. The channel formed by the dust filter pipe 212 forms at least one dust filter port 21201 away from the air separation pipe 211. The outer diameter of the dust filter port 21201 matches the inner diameter of the mounting through hole 1201. The dust filter pipe 212 is arranged on the closed mounting plate 12 in a manner that the dust filter port 21201 corresponds to the mounting through hole 1201, and the dust filter port 21201 is connected to the dust filter space 103. That is, the air separation pipe 211 is arranged on the closed mounting plate 12 through the dust filter pipe 212.

[0032] The gas separation component 20 further includes a dust filter 22 corresponding to the dust filter port 21201. The dust filter 22 includes a dust filter end 221. The dust filter end 221 is used to filter and absorb dust in the air, and the dust filter end 221 is arranged at the dust filter port 21201.

[0033] The exhaust component 30 is arranged in the dust filter box 11, and is used to suck air into the channel formed by each of the air distribution pipes 211, so that the air containing dust in the dust filter space 103 is filtered through the dust filter end 221 in each of the dust filter ports 21201, and the filtered air is discharged to the outside through the channel formed by each of the dust filter pipes 212, the channel formed by each of the air distribution pipes 211 and the exhaust component 30 in turn.

[0034] Those skilled in the art can understand that after the dust-containing air enters the dust filter space 103 from the air inlet 101 through the air inlet space 102, in the process of passing through the dust filter end 221 in each of the dust filter ports 21201 and entering the channel formed by the corresponding dust filter pipe 212, the dust in the dust-containing air will be filtered by the dust filter end 221 and adsorbed on the surface of the dust filter end 221 facing the dust filter space 103.

[0035] Specifically, the air extraction component 30 includes an air extraction member 31, at least one air extraction main pipe 32 and a silencer component 33. The silencer component 33 includes a silencer body 331 and a plurality of shock-isolating silencers 332, and the silencer body 331 forms a silencer space 33101. The plurality of shock-isolating silencers 332 are arranged in the silencer space 33101. The air extraction member 31 is arranged in the dust filter box 11, and the air extraction member 31 has an air extraction pipe 311 for sucking filtered air, and one end of the channel formed by the air extraction pipe 311 forms an air suction port, and the channel formed by the air extraction pipe 311 is connected to the silencer space 33101 through the air suction port. One end of the channel formed by each of the air distribution pipes 211 is connected to the channel formed by the air extraction main pipe 32, and the silencer space 33101 of the silencer body 331 is connected to the channel formed by the air extraction main pipe 32 through a pipeline.

[0036] It can be understood by those skilled in the art that the dust-containing air passes through each of the dust filter ends 221 from the dust filter space 103 to filter the dust, and then enters the channel formed by the air distribution pipe 211 through the channel formed by the corresponding dust filter pipe 212 in turn. The filtered air in the channel formed by each of the air distribution pipes 211 will flow into the channel formed by the exhaust main pipe 32, and enter the silencing space 33101 through the pipe between the silencing space 33101 of the silencing body 331 and the exhaust main pipe 32. At the same time, since the seismic isolation and silencer 332 is provided in the silencing space 33101, the flow rate of the filtered air entering the silencing space 33101 will be slowed down by the seismic isolation and silencer 332, and the filtered air with slowed flow rate will be sucked in by the air inlet of the exhaust pipe 311 and discharged to the outside from the exhaust port of the exhaust member 31.

[0037] It is worth mentioning that the filtered air is blocked by the seismic isolation and silencer 332 to slow down the flow rate, thereby preventing the filtered air from hitting the inner wall of the space inside the vacuum element 31 at too fast a speed and causing the vacuum element 31 to emit noise and abnormal sounds, thereby achieving the purpose of silencing and preventing the staff from being affected by the noise and abnormal sounds and being unable to work normally.

[0038] Preferably, the vibration-isolating and sound-absorbing component 332 is implemented to include sound-absorbing cotton.

[0039] It should be noted that, since both the air intake space 102 and the dust filter space 103 are cavities, when noise enters the air intake space 102 and the dust filter space 103, a cavity effect is generated, and the noise is enhanced. At the same time, when the inner wall of the air intake space 102 and the inner wall of the dust filter space 103 are vibrated, the noise generated by the vibration will also enter the air intake space 102 and the dust filter space 103 to generate a cavity effect, and the noise is enhanced.

[0040] It is worth mentioning that, due to the presence of a large number of pores inside the seismic isolation and silencer 332, when the vibration and noise generated by the operation of the air extraction member 31 are transmitted to the silencer body 331 through the air extraction pipe 311, the vibration and noise generated by the vibration will be absorbed by the pores of the seismic isolation and silencer 332 in the silencer space 33101 and weakened to a predetermined degree, thereby preventing the vibration from being transmitted to the air inlet 101 and the dust filter space 103 and generating noise, thereby preventing the noise from being enhanced in the air inlet space 102 and the dust filter space 103 due to the cavity effect, so as to achieve the purpose of silencing. At the same time, the noise generated by the vibration is prevented from being transmitted from the air extraction member 31 to the air inlet 101 and the dust filter space 103 due to the cavity effect. That is to say, when the vibration and noise generated by the operation of the exhaust member 31 are transmitted to the seismic isolation and silencer 332 in the silencer space 33101 of the silencer body 331 through the exhaust pipe 311, they will be absorbed by the seismic isolation and silencer 332 and weakened to a predetermined degree, so that when the vibration and noise generated by the vibration are transmitted to the air intake space 102 and the dust filter space 103, the cavity effect is avoided to achieve the purpose of silencer.

[0041] Specifically, the silencer component 33 also includes at least one air guide 333. One end of the air guide 333 is arranged on the silencer body 331, and the air guide 333 penetrates into the silencer space 33101 without passing through the silencer body 331, and an opening is formed on the surface of the silencer body 331 and located at the place where the air guide 333 is arranged on the silencer body 331. The opening is connected to the channel formed by the air guide 333. A plurality of seismic isolation silencers 332 are arranged on the outside of the air guide 333 and located in the silencer space 33101. A plurality of air vents 33301 connected to the silencer space 33101 are provided on the surface of the air guide 333, and the air vents 33301 are connected to the channel formed by the air guide 333.

[0042] In this embodiment, preferably, the air extraction pipe 311 is connected to the channel formed by the air guide member 333 in a manner that the air intake port corresponds to the opening of the air guide member 333 .

[0043] Those skilled in the art will appreciate that, during the process of forming a negative pressure at the air inlet of the exhaust pipe 311 and sucking the filtered air from the silencing space 33101 through the channel formed by the air guide 333 and the air vents 33301 in sequence, the filtered air enters the silencing space 33101 and is slowed down by the seismic isolation and silencer 332. At the same time, the filtered air with slowed down flow in the silencing space 33101 will flow into the channel formed by the air guide 333 from the plurality of air vents 33301, and will be sucked into the air inlet of the exhaust pipe 311 and discharged to the outside through the exhaust port of the exhaust piece 31.

[0044] Among them, since the surface of the air guide 333 is provided with a plurality of the air vents 33301 connected to the silencing space 33101, a negative pressure is formed at the air intake port of the exhaust pipe 311, and the flow rate of the filtered air sucked from the silencing space 33101 through the channel formed by the air guide 333 and the air vents 33301 in turn will be increased, so as to increase the flow rate of the filtered air discharged by the exhaust member 31, thereby avoiding the reduction in the flow rate of the filtered air sucked into the air intake port due to the seismic isolation and silencer 332 reducing the flow rate of the filtered gas.

[0045] In another variant embodiment, more preferably, one end of the channel formed by each of the air distribution pipes 211 is connected to the channel formed by the exhaust main pipe 32, one end of the pipe between the muffler body 331 and the exhaust main pipe 32 corresponds to the opening of the air guide 333, and the channel formed by the pipe is connected to the channel formed by the air guide 333. The other end of the pipe between the muffler body 331 and the exhaust main pipe 32 is connected to the channel formed by the exhaust main pipe 32. The air inlet of the exhaust pipe 311 is connected to the silencing space 33101.

[0046] Those skilled in the art will appreciate that the air filtered by the exhaust pipe 311 will enter the channel formed by the air distribution pipe 211 from the channel formed by each of the dust filter pipes 212, and will be merged into the channel formed by the exhaust main pipe 32 through the channel formed by each of the air distribution pipes 211, and will enter the channel formed by the air guide member 333 in the silencing space 33101 from the channel formed by the pipe between the exhaust main pipe 32 and the exhaust pipe 311, and will then enter the silencing space 33101 through a plurality of air vents 33301, so as to increase the flow rate of the filtered air that enters the silencing space 33101 at the same time and whose flow rate is slowed down by the seismic isolation and silencer 332.

[0047] Preferably, the muffler component 33 further includes two air guides 333. The air extraction pipe 311 is connected to the channel formed by one of the air guides 333 in a manner that the air inlet corresponds to the opening of one of the air guides 333. One end of the channel formed by each of the air distribution pipes 211 is connected to the channel formed by the air extraction main pipe 32, one end of the pipe between the muffler body 331 and the air extraction main pipe 32 corresponds to the opening of another air guide 333, and the channel formed by the pipe is connected to the channel formed by another air guide 333. The other end of the pipe between the muffler body 331 and the air extraction main pipe 32 is connected to the channel formed by the air extraction main pipe 32.

[0048] It is worth mentioning that, since the surface of the air guide 333 is provided with a plurality of the vents 33301 connected to the silencing space 33101, a negative pressure is formed at the air inlet of the exhaust pipe 311, and the flow rate of the filtered air sucked from the silencing space 33101 through the channel formed by one of the air guides 333 and the vents 33301 in turn will be increased. At the same time, the flow rate of the filtered air that enters the silencing space 33101 through the plurality of vents 33301 of another air guide 333 and is slowed down by the seismic isolation and silencer 332 will also be increased. This avoids the flow rate of the filtered air sucked into the air inlet being reduced due to the seismic isolation and silencer 332 reducing the flow rate of the filtered gas, thereby providing a guarantee for the flow rate of the filtered air discharged to the outside from the exhaust port of the air extraction member 31 per unit time.

[0049] Preferably, the muffled pulse bag dust removal device further includes a dust blowing assembly 40. The dust blowing assembly 40 is arranged in the dust filter box 11. The dust blowing assembly 40 can blow air into the channel formed by the air distribution pipe 211, and make the gas blown into the channel formed by the air distribution pipe 211 enter the channel formed by the dust filter pipe 212 and pass through the dust filter end 221 at the dust filter port 21201, so as to blow the dust on the surface of the dust filter end 221 into the dust filter space 103, so as to achieve the purpose of cleaning the dust on the surface of the dust filter end 221.

[0050] Specifically, the dust blowing assembly 40 includes a blower 41 and at least one air duct 42. The blower 41 is disposed on the dust filter box 11, and is connected to the channel formed by each of the air distribution pipes 211 through the channel formed by the air duct 42, so that the blower 41 can blow air into the channel formed by the air distribution pipe 211 through the channel formed by the air duct 42.

[0051] Preferably, the air extraction component 30 further includes an air extraction connection control member 34. The air extraction connection control member 34 is disposed on the air extraction pipe 311 in a manner that can control the opening and closing of the passage formed by the air extraction pipe 311.

[0052] It is worth mentioning that since the exhaust connection control part 34 can control the opening and closing of the channel formed by the exhaust pipe 311, when the blowing member 41 blows air into the channel formed by the air distribution pipe 211 through the channel formed by the air guide pipe 42, the channel formed by the exhaust pipe 311 can be disconnected, thereby preventing the gas blown into the channel formed by the air distribution pipe 211 from passing through the channel formed by the exhaust main pipe 32, the silencer space 33101, the channel formed by the air guide 333 and the channel formed by the exhaust pipe 311 in sequence and being discharged to the outside from the exhaust port of the exhaust member 31, so that the gas blown into the channel formed by the air distribution pipe 211 through the channel formed by the air guide pipe 42 by the blowing member 41 can smoothly enter the channel formed by the dust filter pipe 212 and pass through the dust filter end 221 at the dust filter port 21201, so as to blow the dust on the surface of the dust filter end 221 into the dust filter space 103, thereby achieving the purpose of cleaning the dust on the surface of the dust filter end 221.

[0053] Preferably, the exhaust connection control element 34 is implemented by, but not limited to, being selected from, a connection valve.

[0054] Preferably, the dust blowing assembly 40 further includes a dust blowing connection control member 43. The dust blowing connection control member 43 is arranged on the air duct 42 in a manner that can control the opening and closing of the channel formed by the air duct 42. When the dust blowing connection control member 43 blocks the connection of the channel formed by the air duct 42, the filtered air can smoothly pass through the channel formed by the dust filter pipe 212, the channel formed by the air distribution pipe 211, the channel formed by the exhaust main pipe 32, the silencing space 33101, the channel formed by the air guide 333 and the channel formed by the exhaust pipe 311, and be discharged from the exhaust port of the exhaust member 31 to the outside.

[0055] Preferably, the dust blowing connection control member 43 is implemented by, but not limited to, being selected from a connection valve.

[0056] Specifically, the gas separation component 21 further includes a pulse valve 213 corresponding to the dust filtering pipe 212 , and the pulse valve 213 is disposed on the dust filtering pipe 212 in a manner that can control the on-off of a channel formed by the dust filtering pipe 212 .

[0057] It is worth mentioning that when the dust filter pipe 212 is passed with gas, the pulse valve 213 can be used to block the channel formed by the dust filter pipe 212 connected to the channel formed by the gas distribution pipe 211, so that after the gas in the channel formed by the gas distribution pipe 211 is compressed to a predetermined state, the pulse valve 213 is instantly opened to connect the channel formed by the dust filter pipe 212 with the channel formed by the gas distribution pipe 211, and the compressed gas passes through the dust filter end 221 at the dust filter port 21201 at a predetermined speed to blow the dust on the surface of the dust filter end 221 into the dust filter space 103. At the same time, when the compressed gas passes through the dust filter end 221 at the dust filter port 21201 at a predetermined speed, the dust filter end 221 will be impacted by the compressed gas at a predetermined speed, so that the dust on the surface of the dust filter end 221 is impacted and falls off.

[0058] Specifically, the dust filter element 22 further includes a dust filter side portion 222. The dust filter side portion 222 is connected to the circumference of the dust filter end portion 221 in an enclosed manner and extends into the dust filter space 103 to form a ventilation space 2201 between the dust filter end portion 221 and the dust filter side portion 222.

[0059] It is understood by those skilled in the art that when the dust-containing air in the dust filter space 103 is subjected to the suction force of the dust filter port 21201, the dust-containing air in the dust filter space 103 will first enter the ventilation space 2201 through the dust filter side portion 222 to complete the first filtration of the dust-containing air, wherein the dust in the dust-containing air will be partially removed and adsorbed on the surface of the dust filter side portion 222. At the same time, when the first filtered air in the ventilation space 2201 is subjected to the suction force of the dust filter port 21201, it will enter the channel formed by the dust filter pipe 212 from the ventilation space 2201 through the dust filter end portion 221 at the dust filter port 21201, and completely filter the dust in the dust-containing air.

[0060] It is worth mentioning that, since the air containing dust in the dust filter space 103 is filtered by the dust filter side portion 222 and the dust filter end portion 221 successively, the dust content in the air will be more significantly reduced after the dust in the dust-containing air is filtered.

[0061] Among them, since the dust in the dust-containing air is filtered by the dust filtering side portion 222 and the dust filtering end portion 221 in sequence, the frequency of dust accumulation on the surface of the dust filtering end portion 221 requiring cleaning is reduced.

[0062] Preferably, the device body 10 further includes a plurality of bag-supporting members 13 , and the bag-supporting members 13 are used to stabilize the dust filtering side portion 222 .

[0063] Specifically, a plurality of the bag-supporting members 13 are disposed on the closed mounting plate 12, and each of the bag-supporting members 13 is attached to the circumferential surface of the dust filter side portion 222 to stabilize the dust filter side portion 222. In other words, the dust filter side portion 222 is stabilized by the bag-supporting members 13 to maintain the ventilation space 2201 formed between the dust filter side portion 222 and the dust filter end portion 221.

[0064] It is worth mentioning that when the compressed gas passes through the dust filter end 221 at the dust filter port 21201 at a predetermined speed, the dust filter end 221 will be impacted by the compressed gas at a predetermined speed, and the dust on the surface of the dust filter end 221 will fall off due to the impact. At the same time, the gas passing through the dust filter end 221 will enter the ventilation space 2201, and form an air pressure difference between the inner and outer sides of the dust filter side 222. The dust filter side 222 will shake due to the air pressure difference to shake the dust on the surface of the dust filter side 222 into the dust filter space 103. Among them, since the dust filter side 222 is stabilized by the bag support member 13, the dust filter side 222 is prevented from closing the ventilation space 2201 when it is shaken by the air pressure, thereby preventing the dust on the surface of the dust filter end 221 from being impacted and unable to fall into the dust filter space 103 due to the closure of the ventilation space 2201.

[0065] Specifically, the inner diameter of the inner wall of the air intake space 102 gradually decreases from close to the dust filtering space 103 to far away from the dust filtering space 103, and forms a dust collecting port 104 for collecting dust.

[0066] Preferably, the soundproof pulse bag dust removal equipment further includes a dust collecting member 50 for storing dust, and the dust collecting member 50 is located below the dust collecting port 104 .

[0067] It is worth mentioning that the dust that falls off from the dust filter end 221 and the dust filter side 222 and enters the dust filter space 103, after falling into the air intake space 102 due to gravity, will slide along the inner wall of the air intake space 102 toward the dust collecting port 104, and fall into the dust collecting part 50 through the dust collecting port 104 to complete the collection of dust. Since the inner diameter of the inner wall of the air intake space 102 gradually decreases from close to the dust filter space 103 to far away from the dust filter space 103, the dust can more smoothly slide to the dust collecting port 104 and enter the dust collecting part 50 due to gravity.

[0068] Preferably, the device body 10 further includes a guide member 14. The guide member 14 is disposed on the inner wall of the air intake space 102, and the guide member 14 spirally extends from the inner wall of the air intake space 102 close to the dust collecting port 104 to close to the dust filtering space 103, so that the air containing dust entering the air intake space 102 from the air intake port 101 can be guided by the dust collecting port 104 to enter the dust filtering space 103 after entering the air intake space 102, so that the process of the air containing dust entering the dust filtering space 103 is smoother.

The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
