Detailed Description

In order to make the technical field better understand the solution of the present invention, the present invention will be further described in detail with reference to the following embodiments.

As shown in fig. 2, the novel steel brush magnetic force pig that this patent provided links together front end bowl type leather cup 3, permanent magnet 5 and rear end bowl type leather cup 3 by central skeleton 6 in order, and central skeleton 6 plays a holistic effect of linking, and the front end of central skeleton 6 is connected with wire rope cover 1, and the front surface of front end bowl type leather cup 3 foremost is equipped with anticollision head 2, all installs wire brush 4 directly over every permanent magnet 5. The steel wire rope sleeve 1 has the function that the ball collecting device can be used for pulling out the ball collecting barrel of the pipe cleaner after the pipe cleaning operation is finished; the anti-collision head 2 is used for playing a role of buffering when the pipe cleaner collides with the blind plate, so that the blind plate is prevented from being damaged by collision; the both ends of novel steel brush magnetic force dredging pipe ware all are equipped with bowl type leather cup 3, front end bowl type leather cup 3 and rear end bowl type leather cup 3 mainly play sealed effect, guarantee that the dredging pipe ware is airtight in the pipeline, pipeline pressure differential around the pressure effect produces, guarantee the operation of dredging pipe ware, and be equipped with two front end bowl type leather cups 3 in the place ahead of permanent magnet 5, anterior two bowl type leather cups have better sealing performance and support ability for a bowl type leather cup, the gesture of dredging pipe ware is incorrect when crossing elbow and deformation point, a sealed leather cup probably has gas leakage phenomenon, and this phenomenon can be avoided to two leather cups. The permanent magnet 5 is used for magnetizing the steel wire brush 4 above the permanent magnet by utilizing the magnetic field intensity of the permanent magnet, so that the rigidity and the supporting capability of the steel wire brush 4 are increased, the pipe cleaning capability of the steel wire brush 4 is improved, the steel wire brush 4 can conduct the magnetism of the permanent magnet 5, a closed magnetic field loop is established, impurities on the pipe wall are scraped, and ferromagnetic impurities in the pipeline are adsorbed.

Novel steel brush magnetic force pig is equipped with front and back two sets of permanent magnet 5 and wire brush 4 between 6 front end bowl type leather cup 3 of central skeleton and rear end bowl type leather cup 3, and the width size of permanent magnet 5 and wire brush 4 increases, among the original 610 pig, the width of permanent magnet and wire brush is 80mm and 50mm respectively, and novel steel brush magnetic force pig, when being used for clearing up the pipeline that the pipe diameter is 610mm, the width of permanent magnet 5 is about 136mm, the width of wire brush 4 is about 136mm, increased the scraping area of pig to the pipe wall, can show the effect of promoting the dredging pipe. When two sets of permanent magnets 5 are installed, the N/S level of the front permanent magnet close to the steel wire rope sleeve 1 is arranged outwards, the S/N level of the rear permanent magnet far away from the steel wire rope sleeve 1 is arranged outwards, so that a magnetic field generated between the two sets of permanent magnets 5 in the front and the rear generates a closed magnetic field loop through the conduction of the steel wire brush 4 above the magnetic field loop and the pipe wall, the magnetic field intensity and the magnetic field area of the permanent magnets 5 are equivalently amplified, and the adsorbability of ferromagnetic impurities in the pipeline is greatly improved. The impurity amount of the novel steel brush magnetic pipe cleaner for cleaning the impurities in the pipeline at one time is 5-10 times of that of the common rigid brush magnetic pipe cleaner.

Install directly over permanent magnet 5 steel brush 4, and the material optional use 65Mn spring steel of steel brush 4, have very strong magnetic conductivity, steel brush 4 is by the rigidity reinforcing after the magnetization, increased the scraping ability to the pipe wall, the support ability of novel steel brush magnetic force dredging pipe ware has been improved simultaneously, for this dredging pipe ware stability and centering nature of operation all provide the powerful guarantee in the pipeline, avoid bowl type leather cup 3's eccentric wear phenomenon, the strong support ability of steel brush 4 also lets heavy dredging pipe ware save the supporting wheel structure, can simplify heavy magnetic force dredging pipe ware's structure.
