Detailed Description

For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings. It is noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example (b):

an exhaust pipe for a Roots blower is shown in figure 2 and comprises an exhaust pipe 1, an electromagnetic coil and a storage battery 2, wherein the storage battery 2 energizes the electromagnetic coil to enable the electromagnetic coil to adsorb iron chips on the inner wall of the exhaust pipe 1. Exhaust pipe one side be equipped with the filtering component who can dismantle the connection, filtering component can the gaseous departure of iron fillings year.

As shown in figure 5, one side of the filter assembly is provided with an annular scraper 3 which is contacted with the inner wall of the exhaust pipe 1, and the scraper 3 is detachably connected with the filter assembly. Scraper blade 3 can clear up the iron fillings on the 1 inner wall of blast pipe. The section of the scraper 3 is triangular, and the tip end of the scraper is contacted with the inner wall of the exhaust pipe 1, so that the structure ensures good cleaning effect.

As shown in fig. 2 and 4, the filter assembly includes four mounting frames 4 and four filter screen units 10, and the use positions of the filter screen units 10 can be changed, i.e., the use period of the filter screen is prolonged, and the cleaning times are reduced; and the filter screen unit 10 is convenient for reducing loss and prolonging the service life by changing the use position.

Filter screen unit 10 and mounting bracket 4, mounting bracket 4 and blast pipe 1 be can dismantle the connection, the structure of conveniently dismantling can reduce operating time, easy to assemble or clear up, raises the efficiency.

As shown in fig. 3 and 4, the mounting bracket 4 is provided with a square structure, and a connecting bolt 11 is arranged on one side of the mounting bracket 4. One end of the connecting bolt 11 is provided with an arc-shaped clamping plate 12 which is contacted with the exhaust pipe 1. The structure of the filtering component and the arrangement of the connecting bolt 11 are matched with the scraper 3 to be replaced, so that the device is suitable for exhaust pipes 1 of different sizes, and the application range of the device is widened.

As shown in fig. 4, the mounting frame 4 includes a frame 5, a cross 6, a back plate 7 and a front plate 8, a filter screen unit 10 is disposed between the back plate 7 and the front plate 8, and a fixing bolt 9 connected with the cross 6 is disposed on the front plate 7. The use position of the filter screen unit 10 can be changed by separating the fixing bolt 9 from the cross 6 and removing the front plate 8.

During the use, stretch into the blast pipe 1 with scraper blade 3 to fix mounting bracket 4 on blast pipe 1 through connecting bolt 11, and filter screen unit 10 contacts with blast pipe 1 one side this moment, prevents that iron fillings from spilling in the clearance of filter screen unit 10 and blast pipe 1. Then, the battery 2 energizes the electromagnetic coil on the inner wall of the exhaust pipe 1, so that the electromagnetic coil can have the effect of adsorbing iron filings. The tip of blast pipe 1 is provided with filter assembly, and the iron fillings that the roots's fan mix with when exhaust gas filters through filter assembly, and through the solenoid cooperation, adsorbs iron fillings on 1 inner walls of blast pipe.

After the iron scraps are adsorbed too much on the inner wall of the exhaust pipe 1, the mounting frame 4 is detached from the exhaust pipe 1 through the connecting bolt 11, the scraper 3 can clean the inner wall of the exhaust pipe 1 in the process, and the filter screen unit 10 can be directly cleaned after the scraper is detached.

When clearing up filter screen unit 10, the user can also demolish fixing bolt 9 and front bezel 8 from cross 6, can take off filter screen unit 10 this moment and clear up one by one, and the convenience is cleared up and is cleared up cleaner.

After the clearance, when installing filter screen unit 10 on mounting bracket 4, the user can freely change the position that filter screen unit 10 is located mounting bracket 4 center department, through this kind of assembled mode, can effectively reduce the loss of filter screen, extension filter assembly's life.
