[0030] Combined with appendix Figure 1 and2 This embodiment of an automatic pipe cleaning iron remover includes an iron remover housing 1, which is a long tubular structure with a first slurry inlet 1a and a cleaning liquid inlet 1b at the upper end and a second slurry inlet 1c at the lower end; a magnetic rod protective shell 2, disposed inside the iron remover housing 1, which is a hollow cylinder and coaxially arranged with the iron remover housing 1; a magnetic rod 3, disposed inside the magnetic rod protective shell 2, which is fixed relative to and coaxially arranged with the magnetic rod protective shell 2; and a driving structure 4, disposed on the iron remover housing 1 and used to control the rotation of the magnetic rod protective shell 2 and the magnetic rod 3 within the iron remover housing 1. The driving structure 4 is preferably disposed on... The upper end of the iron separator housing 1 is designed to prevent contamination by slurry. A spiral liner 5 is also provided inside the iron separator housing 1. The spiral liner 5 is fixed relative to the iron separator housing 1, and its inner circumference abuts against the magnetic rod protective shell 2. A spiral cavity 5a is formed between the spiral liner 5 and the magnetic rod protective shell 2. The spiral cavity 5a extends from one end of the iron separator housing 1 to the other end. The first slurry inlet 1a and the second slurry inlet 1c are both connected to the spiral cavity 5a. At least one end of the magnetic rod protective shell 2 is connected to a non-magnetic extension 6, which is at least partially located within the spiral liner 5.

[0031] The iron removal and filtration steps of this automatic pipeline cleaning iron remover are as follows: the slurry rotates and flows in the spiral cavity 5a between the spiral liner 5 and the magnetic rod protective shell 2. The slurry has a long contact time with the magnetic rod 3, which improves the filtration effect on magnetic substances in the slurry. The magnetic substances are adsorbed on the surface of the magnetic rod protective shell 2.

[0032] The cleaning steps of the iron removal filter of this automatic pipeline cleaning iron remover are as follows: cleaning fluid is introduced into the cleaning fluid port 1b, passing through the spiral cavity 5a between the magnetic rod protective shell 2 and the spiral liner 5, cleaning the cavity. At the same time, the drive structure 4 drives the magnetic rod protective shell 2 to rotate. The rotation direction of the magnetic rod protective shell 2 is the same as the spiral direction of the spiral cavity 5a. The surface of the magnetic rod protective shell 2 rubs against the spiral liner 5. The magnetic material adsorbed on the surface of the magnetic rod protective shell 2 is scraped to the non-magnetic extension 6 at the lower end of the magnetic rod protective shell 2 and then detaches from the magnetic rod protective shell 2.

[0033] This automatic pipeline cleaning iron separator has a simple structure and is easy to operate. During the iron removal and filtration process, the slurry has a long contact time with the magnetic rods, which improves the filtration effect on magnetic substances in the slurry.

[0035] As an optional embodiment of the present invention, the magnetic rod protective shell 2 is made of stainless steel.

[0036] As an optional embodiment of the present invention, the drive structure 4 includes a drive motor 41 and a reducer 42. The output shaft of the reducer 42 and the magnetic rod protective shell 2 are connected by a magnetic rod shaft 43. The transmission shaft of the reducer 42 is connected to the magnetic rod shaft 43 by a coupling and a key pin. The magnetic rod shaft 43 is welded to the magnetic rod protective shell 2. The drive motor 41 drives the magnetic rod protective shell 2 to rotate after being reduced in speed by the reducer 42.

[0037] As an optional embodiment of the present invention, the iron separator housing 1 is provided with a connecting seat 7 for mounting the drive structure 4. The connecting seat 7 is installed between the iron separator housing 1 and the drive structure 4. The connecting seat 7 is provided with a bearing 8 and a skeleton oil seal 9 that cooperate with the magnetic rod shaft 43, so that the magnetic rod shaft 43 can rotate and prevent slurry leakage.

[0038] As an optional embodiment of the present invention, the connecting seat 7 includes an upper connecting seat 71 and a lower connecting seat 72 that are detachably connected. The upper connecting seat 71 and the lower connecting seat 72 are connected by bolts. The upper connecting seat is connected to the drive structure 4, and the lower connecting seat 72 is connected to the magnetic rod protective shell 2. The connection position of the drive shaft of the reducer 42 and the magnetic rod shaft 43 is located inside the upper connecting seat 71. The drive structure 4 is installed on the upper connecting seat 71. The bearing 8 and the skeleton oil seal 9 are installed on the lower connecting seat 72 at one end near the upper connecting seat 71, so as to realize the modular installation and connection of the above components, improve the assembly efficiency, and facilitate later maintenance.
