In order to improve the effect of gas filtration and prevent the gas filter from being blocked by foreign matters and not being capable of working normally in work, the invention provides the gas filter which can be used for effectively cleaning the filter, improves the filtering effect and lightens the workload of workers.
Referring to fig. 1 to 2, the gas filter provided by the present invention mainly includes a main pipe 1, a filtering pipe 2, and a foreign matter collecting device 3, wherein the filtering pipe 2 is communicated with the main pipe 1, the foreign matter collecting device 3 is disposed below the filtering pipe 2, a filtering structure 21 and a cleaning component are disposed in the filtering pipe 2, the filtering structure 21 is mainly used for filtering gas, and the cleaning component is used for cleaning the filtering structure 21, so that the filtering structure 21 is prevented from being excessively long in use time, and foreign matters adhere to the filtering structure 21, thereby affecting the filtering effect of the filtering structure 21; a baffle plate 11 is arranged in the main pipeline 1, the baffle plate 11 is contacted with the end part of the filtering structure 21, a gas inlet 12 is arranged on the baffle plate 11 and used for inputting gas from the main pipeline 1 into the filtering structure 21 in the filtering pipeline 2 for filtering, a baffle plate 23 is arranged on the baffle plate 11 and used for controlling the on-off of the gas inlet 12, in the invention, as shown in figure 2, the filtering structure 21 comprises a solid part 211 which is positioned at the upper part and can block the gas from flowing and a filtering part 212 which is positioned at the lower part and can filter the gas; the cleaning assembly of the present invention mainly comprises a blowing device 216 and a driving device 215, wherein the blowing device 216 is used for introducing compressed air into the filtering pipeline 2, so that the outside of the compressed air filtering structure 21 is blown into the inside to blow off foreign matters attached to the filtering structure 21, and the driving device 215 can control the filtering structure 21 to move up and down to control the opening and closing of the baffle plate 23.
Specifically, the driving device 215 controls the filter structure 21 to move up and down in the filter pipe 2 so as to control the opening and closing of the baffle plate 23, and the operating principle is that the baffle plate 23 is arranged on the partition plate 11, and when the driving device 215 controls the filter structure 21 to move up, the filter structure 21 lifts up the baffle plate 23 so as to open the baffle plate 23; when the driving device 215 controls the filter structure 21 to move downwards, the filter structure 21 does not exert an ejecting force on the baffle plate 23, so that the baffle plate 23 is closed due to self weight.
Thus, when the filter structure 21 in the filter tube 2 needs to be cleaned, referring to fig. 2, the filter structure 21 moves downward in the filter tube 2 by the driving of the driving device 215, the baffle 23 is closed to block the gas from entering the filter structure 21, the solid portion 211 blocks the gas in the filter structure 21 from leaking, the baffle 23 cooperates with the solid portion 211 to form a closed space inside the filter tube 2, the air blowing device 216 blows the compressed air from outside to inside of the filter structure 21 to blow off the foreign matters attached to the filter structure 21, and the foreign matters collecting device 3 collects the blown off foreign matters, as can be understood, the installation position of the air blowing device 216 shown in fig. 1 to 4 is located between the outer surface of the filter structure 21 and the inner surface of the filter tube 2, so that the compressed air can be ensured to enter and exit the inner surface of the filter structure 21, and the attached foreign matters on the filter structure 21 can be blown off
It should be noted that, the structure shown in fig. 1 and fig. 2 is only one specific embodiment of the present invention, and in the present invention, an air extraction device may be installed, and the air extraction device may be installed at any position in the foreign matter collecting device 3, so long as the air extraction device 216 blows the foreign matter attached to the filter structure 21, and the air extraction device may extract the blown foreign matter out of the filter pipe 2 and into the foreign matter collecting device 3. The mounting position of the baffle 23 is just one embodiment of the present invention, and the baffle 23 may be mounted at the end of the solid portion 211 near the partition 11.
It should be noted that, in the present invention, the positional relationship between the filtering conduit 2 and the main conduit 1 may be not only as shown in fig. 1 and 2, but also may be vertically disposed.
In the gas filter of the present invention, one end of the main pipe 1 is a gas inlet 13, and the other end is a gas outlet 14, as shown in fig. 1 to 2, the partition 11 blocks communication between the gas inlet 13 and the gas outlet 14, after entering the gas inlet 13 of the main pipe 1, the gas cannot directly enter the gas outlet 14 because of the blocking of the partition 11, so as to enter the filtering pipe 2 through the gas inlet 12 arranged on the partition 11 for filtering, and the filtered gas flows to the gas outlet 14. It can be seen that the partition 11 serves as a primary function of isolating the communication between the gas inlet 13 and the gas outlet 14.
In addition, as a specific embodiment of the present invention, there is a gap between the outer surface of the filtering structure 21 and the inner surface of the filtering pipe 2, because the filtering structure 21 mainly functions to filter the gas inputted into the main pipe 1, the filtering structure 21 works to filter the gas when the gas enters the filtering pipe 2, but because the gas has fluidity and air pressure to maintain a certain flow path, if the filtering structure 21 is closely attached to the filtering pipe 2, the gas in the central part may not be filtered, preferably, there is a gap between the outer surface of the filtering structure 21 and the inner surface of the filtering pipe 2, so that the filtering range can be increased and the filtering efficiency can be enhanced.
As shown in fig. 1 and 2, as a specific embodiment of the present invention, the filter structure 21 in the present invention is a cylindrical structure, and in addition to this, the filter structure 21 in the present invention may also be other structures, for example, a filter layer is disposed transversely in the filter structure 21 in the cylindrical structure, so that a better filtering effect can be achieved.
In the present invention, the driving device 215 is used as a device capable of driving the filter structure 21 to move up and down, as shown in fig. 1 to 2, one end of the driving device 215 is connected to the bottom outer surface of the filter structure 21, and the other end is connected to the bottom inner surface of the filter pipe 2. The driving device 215 pushes the filtering structure 21 to move up and down, the upper part of the filtering structure 21 passes through the partition plate 11, the opening at the upper part of the filtering structure 21 is communicated with the gas input port 12, the opening at the upper part of the solid part 211 is communicated with the gas input port 12, two baffles 23 are arranged on the gas input port 12 on the partition plate 11, when the two baffles 23 are mutually connected, the gas input port 12 is closed, when the two baffles 23 are mutually far away, the gas input port 12 is opened, in addition, the driving device 215 also simultaneously controls the position of the solid part 211 on the filtering structure 21, when the gas is required to be filtered, the driving device 215 is used for driving the filtering structure 21 to move upwards, the baffles 23 are opened, the solid part 211 moves upwards, and the gas inlet 13 is communicated with the gas outlet 14 through the filtering part 212 on the filtering structure 21; when the filter structure 21 needs to be cleaned, the driving device 215 is used for driving the filter structure 21 to move downwards, the baffle 23 is closed, and the solid part 211 moves downwards to block the channel between the filter structure 21 and the gas outlet 14, so that a closed space is formed in the filter pipeline 2.
Next, as another embodiment of the present invention, as shown in fig. 3 to 4, one end of the baffle 23 is hinged to the solid portion 211 of the filtering structure 21, and the other end of the baffle 23 is slidably connected to the partition 11, for example, by a slider rail connection manner, at the gas inlet 12. When the gas inlet 12 is opened, the solid part 211 moves upwards under the driving of the driving device 215, the baffle plates 23 rotate around the solid part 211, and simultaneously, along with the movement of the solid part 211, the baffle plates 23 move outwards along the track on the baffle plate 11, so that the gas inlet 12 is opened; similarly, when the gas inlet 12 is closed, the solid part 211 moves downward and the baffle plate 23 rotates around the solid part 211 under the driving of the driving device 215, and at the same time, as the solid part 211 moves, the baffle plate 23 moves along the track on the partition plate 11, the two baffle plates 23 move inward at the same time and approach each other, so that the gas inlet 12 is closed. Preferably, the driving device 215 in the present invention may be a cylinder, and it is understood that the cylinder is a cylindrical metal member guiding the piston to reciprocate linearly in the cylinder, and the gas is compressed by the piston in the cylinder to raise the pressure. In the invention, the cylinder makes a linear reciprocating motion by utilizing the gas in the pipeline, and when the filter structure 21 needs to be cleaned, the piston in the cylinder retracts to drive the air fluctuation in the filter structure 21 so that the foreign matters attached to the filter structure 21 fall off from the filter structure 21.
It should be noted that, the driving device 215 in the present invention may be other driving devices, such as a motor, so long as the filtering structure 21 can move up and down in the filtering pipeline 2.
Further preferably, the filtering pipe 2 and the foreign matter collecting device 3 in the invention can be connected through a connecting flange, and the foreign matter collecting device 3 can be conveniently replaced or maintained by a worker by using the connecting flange. However, the connection flange is only a preferred embodiment of the present invention for connecting the filter tube 2 and the foreign matter collecting device 3, and other connection methods, such as screw connection, tube connection, etc., may be used.
In the invention, the filter structure 21 can be detachably connected, and in the invention, because the driving device 215 needs to drive the filter structure 21, the driving device 215 also plays a role of fixedly connecting the filter structure 21 in the filter pipeline 2, and the driving device 215 and the filter structure 21 can be detachably connected and can be replaced after the service life of the filter structure 21 is reached, so that the effect of the filter pipeline 2 on gas filtration is not affected.
In addition, as a specific embodiment of the present invention, the bottom of the filtering structure 21 is provided with the through hole 213, the through hole 213 is communicated with the foreign matter collecting device 3 through the corrugated tube 214, and the driving device 215 needs to drive the filtering structure 21 to move up and down in the filtering pipeline 2, so that the corrugated tube 214 is selected as a connecting tube to be communicated with the foreign matter collecting device 3 in order to match the movement of the filtering structure 21, and the corrugated tube 214 has elasticity, so that the filtering structure can be matched with the driving device 215 better. It will be appreciated that the use of bellows 214 to connect the filter structure 21 and the foreign matter collection device 3 is only one preferred embodiment of the present invention, and that other connection means may be used, as long as on the one hand it cooperates with the drive device 215 and on the other hand it is in communication with the foreign matter collection device 3.
