Embodiment Construction

[0016] Combine below figure 1 and figure 2 , the present invention is further described:

[0017] figure 1 The location distribution of the gravity filter tank 1, the water jet pipe 2, the filter 3 and the water jet 4 is disclosed in . One port of the water jet pipe 2 is set in the gravity filter tank 1, the other port is connected to the upper end of the water jet device 4, and the lower end of the water jet device 4 is connected to the recoil water pipe located in the sealed water tank 5 of the return pipe, and the gravity filter tank 1 The water jet pipe 2 between the water jet 4 is provided with a filter 3, and the filter 3 ensures that small plastic particles cannot enter the water jet 4.

[0018] figure 2 The structure of the filter is disclosed in , and the filter screen 3 is to filter the small plastic particles in the water jet pipe 2 to ensure that the small particles cannot enter the water jet. Filter 3 comprises two sections of filter connecting pipe 6, filt...

Abstract

The invention relates to a water-blaster blocking-preventing device of a gravity type filter. The water-blaster blocking-preventing device comprises a gravity type filter water bin (1), a water jetting pipe (2), a water-blaster (4) and a water return pipe sealing water box (5), wherein a port of the water jetting pipe (2) is arranged in the gravity type filter water bin (1), the other port of the water jetting pipe (2) is connected with the upper end of the water-blaster (4), and the lower end of the water-blaster (4) is connected with a backlashing water pipe and is positioned in the water return pipe sealing water box (5); the water-blaster blocking-preventing device is characterized in that the filter (3) is arranged on the water jetting pipe (2) arranged between the gravity type filter water bin (1) and the water-blaster (4), and the filter (3) guarantees that small plastic granules do not enter the water-blaster (4). The water-blaster blocking-preventing device provided by the invention has the advantages that the filter is additionally arranged on the front section of the water-blaster of the water jetting pipe of the gravity type filter, a condition that the small plastic granules do not enter the water-blaster is guaranteed, and the water-blaster is kept unobstructed.

Description

technical field [0001] The invention relates to an anti-clogging device in pipeline transportation, in particular to an anti-clogging device for a water ejector of a gravity filter in the sewage treatment of the iron concentrate dehydration process. Background technique [0002] In the field of iron ore concentrate pipeline transportation, the ore pulp transported to the terminal needs to be dehydrated. During the dehydration process, a large amount of sewage will be generated to be treated. The sewage treatment equipment usually used is a gravity filter. Due to the influence of the previous process, the sewage produced after dehydration treatment contains a large number of small plastic particles. These small plastic particles will block the ejector of the gravity filter after the sewage comes to the gravity filter, causing the gravity filter to Unable to recoil normally, the filtering effect of the gravity filter gradually decreases, and finally leads to unusability, which...
