The invention discloses a cooling liquid filtering device for machining. The device comprises a shell. A liquid inlet hopper is arranged at the front end of the shell. The lower portion of the liquid inlet hopper is connected with a liquid inlet pipe. The shell is divided by a partition plate into a front cavity and a rear cavity. The upper portion inside the front cavity is provided with an inclined outer pipe body. A filter net is arranged in the middle inside the front cavity. An inner net pipe is fixed in the outer pipe body through rib strips. A pipe base is arranged in the rear cavity. A channel is arranged in the pipe base. A rotating rod penetrates in the channel and is provided with a small spiral stirring blade and a large spiral stirring blade. A discharge hopper is arranged in the rear cavity. A conveyer is arranged below the discharge hopper. The device has the advantages that cooling liquid and metal impurities are good in separation effect and high in separation efficiency in the whole process, metal impurities and cooling liquid can be effectively separated, cooling liquid can be recycled, environmental pollution can be effectively reduced, the effect of environmental protection is achieved, and the device can save the machining cost.

The invention discloses a high-cleanliness desulfurization and denitrification dust removal device with a circulating synergistic function, and relates to the technical field of desulfurization and denitrification, the high-cleanliness desulfurization and denitrification dust removal device comprises a dust removal assembly, a cooling assembly, a denitrification tower, a bag-type dust remover and a desulfurization tower, the dust removal assembly, the denitrification tower, the bag-type dust remover and the desulfurization tower are fixedly connected with the ground, and the dust removal assembly is connected with the cooling assembly through a pipeline. The end, away from the dust removal assembly, of the cooling assembly is fixedly connected with the denitration tower through a pipeline, the end, away from the cooling assembly, of the denitration tower is connected with the bag-type dust collector through a pipeline, and the end, away from the denitration tower, of the bag-type dust collector is communicated with the desulfurization tower through a pipeline. Separation of the heavy metal impurities is achieved through the electric conduction difference between the heavy metal impurities and conventional impurities, collection and removal circulation is achieved in the whole separation process, and the dust removal rate is increased to a great extent. Independent separation of the heavy metal impurities simplifies subsequent impurity classification treatment steps on one hand, and also provides a basis for secondary recycling on the other hand.
