[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-4 As shown,

[0023] The water coal slurry pipeline magnetic filter comprises a pipeline body 1, a plurality of filter rods 2 are fixedly installed in the pipeline body 1, the inside of the filter rod 2 is a hollow structure, a top cover 3 is fixedly installed at one end of the pipeline body 1, a plurality of magnetic rods 4 corresponding to the filter rod 2 are inserted into the top cover 3, and the magnetic rod 4 is inserted into the inside of the filter rod 2.

[0024] As a preferred implementation manner, a plurality of insertion holes (not shown in the figure) corresponding to the magnetic rod 4 are arranged on the top cover 3. It can be understood that the magnetic rod 4 can be pulled out from the inside of the filter rod 2 by arranging the insertion hole. When the magnetic rod 4 is inserted into the inside of the filter rod 2, a gap exists between the magnetic rod 4 and the filter rod 2, so that the magnetic rod 4 can be pulled out under the action of an external force. Since the magnetic force for adsorbing metal impurities does not need to be too strong, the magnetic force provided by the magnetic rod 4 to the filter rod 2 is sufficient to enable the filter rod 2 to adsorb metal impurities.

[0025] As a preferred implementation manner, one end of the magnetic rod 4 is inserted into the inside of the filter rod 2, the other end of the magnetic rod 4 extends to the outside of the top cover 3 and is fixedly connected with a support 5, and the magnetic rod 4 can move up and down in the inside of the filter rod 2. It can be understood that the magnetic rod 4 can move up and down in the inside of the filter rod 2 by arranging the insertion hole. When the magnetic rod 4 is pulled out, the filter rod 2 loses the magnetic force, so that the metal impurities fall off, thereby facilitating the cleaning of the metal impurities. The support 5 is arranged to facilitate the pulling out of the magnetic rod 4.

[0026] As a preferred implementation manner, the top cover 3 is arranged on the top surface of the pipeline body 1, and a feeding port 6 and a discharging port 7 are arranged at the front end and the rear end of the pipeline body 1 respectively. The arrangement of the feeding port 6 and the discharging port 7 enables the filter to form a pipeline type filtering structure, and the filtering efficiency is greatly improved.

[0027] As a preferred implementation manner, a plurality of fixing rings 8 are fixedly installed at the top end of the top cover 3, a plurality of fasteners 9 are arranged on the top outer wall of the pipeline body 1 and correspond to the plurality of fixing rings 8, and the fixing ring 8 and the fastener 9 are fixedly connected through bolts. The fixing ring 8 and the fastener 9 are arranged to enable the top cover 3 to be fixedly connected to the pipeline body 1, and to enable the top cover 3 to be detachably installed, thereby achieving better use effect.

[0028] As a preferred implementation manner, a connecting block 10 is arranged between the magnetic rod 4 and the support 5, the magnetic rod 4 and the connecting block 10 are fixedly connected, and the connecting block 10 and the support 5 are fixedly connected. The connecting block 10 is arranged to limit the magnetic rod 4.

[0029] As a preferred embodiment; the material of the filter stick 2 is stainless steel, and the material of the magnetic stick 4 is magnet; so that the magnetic force on the magnetic stick 4 can be transmitted to the filter stick 2, so that the filter stick 2 has magnetic force adsorption metal impurities.

[0030] As a preferred embodiment; the filter stick 2 is arranged in the inner circumference of the pipeline body 1. The purpose of this design is: the filter stick 2 can be evenly laid on each position in the pipeline body 1, which can better adsorb metal impurities.

[0031] The working principle of the utility model is: during filtration, the slurry can enter from the feed inlet 6 and be discharged from the discharge outlet 7, when passing through the filter stick 2, the metal impurities in the slurry will be adsorbed by the filter stick 2, after a period of filtration, the feeding can be stopped, then the magnetic stick 4 is pulled out, so that the filter stick 2 loses magnetism, the metal impurities automatically fall off, and then the cleaning work of the metal impurities can be completed by washing with clean water, in the process, the metal impurity treatment time is shorter, thereby effectively ensuring the filtration efficiency of the filter.

[0032] It should be pointed out that the main problem existing in the prior art is: when the filter screen is full of metal impurities, the metal impurities on the filter screen need to be cleaned, generally, the filter screen needs to be disassembled for cleaning, but this not only wastes manpower, but also takes a long time to install and disassemble, thereby reducing the filtration efficiency.

[0033] Therefore, after the improvement of the present application, the metal impurities in the slurry are filtered by the filter, which not only has good filtration effect, but also is convenient for cleaning the metal impurities, saves time and effort, is convenient and fast, and effectively improves the filtration efficiency of the slurry, and has high practicality.

[0034] The above embodiments only describe the preferred embodiments of the utility model, and do not limit the scope of the utility model, and various deformations and improvements of the technical scheme of the utility model made by ordinary engineering technicians in the art without departing from the design spirit of the utility model shall fall within the protection scope determined by the claims of the utility model.
