The present application relates to the technical field of flue gas purification equipment, and discloses a smoke purifier for laser processing of energy storage batteries, including a pre-stage filter, the pre-stage filter is connected to a suction head, the pre-stage filter filters out larger particles in the smoke, the pre-stage filter includes a shell, the middle part of the shell is provided with a filter element, the filter element is arranged horizontally, one side of the shell is connected to the suction head, the other side of the shell is connected to a branch pipe, and the filter element is arranged between the branch pipe and the suction head. In the smoke purifier for laser processing of energy storage batteries, a pre-stage filter is arranged near the suction head, and larger smoke is filtered out by the pre-stage filter in time to avoid the accumulation of smoke in the pipeline. Secondly, during backblowing, backblowing and vibration are carried out simultaneously to enhance the backblowing effect, and the smoke that falls off due to backblowing can be blown to one side for accumulation or blown out directly without falling into the pipeline.

The application discloses a separated cutting fluid filtering module for a machine tool and a processing method, relates to the technical field of cutting fluid filtering, and comprises a support frame which is detachably connected to the outside of the machine tool, a filtering processing shell is fixedly connected inside the support frame, a liquid inlet valve for liquid inlet is arranged at the top of the filtering processing shell, a liquid outlet valve for liquid outlet is arranged outside the filtering processing shell, and a filtering plate for filtering is fixedly connected inside the filtering processing shell; the fixedly-connected communication rod is driven to rotate by a first gear, and then the communication rod drives the connecting head at the top of the filtering plate to rotate, so that the dust suction heads on the multiple communication frames comprehensively suck dust on the filtering plate; when the communication frame rotates, the rotationally-connected poking frame rotates together; the poking frame is engaged with the meshing teeth arranged inside the protection ring through the first bevel gear fixedly connected at one end, so that the poking frame continuously rotates, the position of the metal dust suction head on the filtering plate is pushed, and the cleaning effect is provided.

The utility model discloses a high-precision pulse back-blowing silicon powder filtering device. The device comprises a filter shell, a back-blowing assembly, a filtering assembly and an ash discharging device, and a back-blowing pipeline central gas distribution structure is adopted, so that the back-blowing effect is enhanced, and the service life of equipment is prolonged. And the shell is additionally provided with a purging opening, and the outer wall surface is additionally provided with a bin wall vibrator, so that the powder flowability is improved, the silicon powder is prevented from being stacked and bridged, and the silicon powder is ensured to be discharged smoothly. The filter element and the pattern plate are both of a double-end fixing structure, the structural stability is effectively guaranteed, and filter element damage and sealing failure caused by impact vibration of blowback airflow are prevented. A high-precision sintered metal filter element is adopted as a filter element, reduction tail gas, emptying tail gas or replacement gas is purified, it is guaranteed that no other impurities are introduced, and the product discharging quality is guaranteed. Intercepted silicon powder particles can still be recycled as system byproducts, and the good expectation of reducing cost and improving efficiency is achieved.

The utility model discloses a vacuum filtration blowback device and a vacuum dryer, which belong to the technical field of chemical equipment and comprise a gas pipeline module and a filtration module, the gas pipeline module comprises a main gas pipeline and two auxiliary gas pipelines; the bottom of the gas main pipeline is inserted into the filtering module; one ends of the two auxiliary gas pipelines are communicated with the main gas pipeline, and the other ends are respectively communicated with the vacuum pump and the gas source; and a valve is arranged at the other end of each gas auxiliary pipeline. According to the utility model, the valve is arranged on the vacuumizing pipe, so that the pressure drop loss is reduced, the back flushing effect is improved, the gas pipeline module and the filtering module of the vacuum filtering and back flushing device are convenient to disassemble and assemble through the modular design, and the cleaning difficulty of the filtering module and the operation difficulty in the equipment maintenance process are reduced.
