5results about How to "Thorough cleaning" patented technology

The invention discloses a chemical safety production dust removal device which comprises a connecting pipeline, a filtering pipeline, a dust discharging pipeline and a cloth bag piece, the cloth bag piece comprises an upper disc, a lower disc, a cloth bag sleeve and a spring arranged in the cloth bag sleeve and connected with the lower disc, the device is provided with a cleaning pipeline, the spring is driven to swing to assist in dust falling when high-pressure gas is blown in, and a driving device is arranged at the bottom of the dust discharging pipeline. A motor drives a cam to rotate, a cam guide groove and a connecting rod mechanism are used for driving a transverse pressing block to ascend, a spring is compressed through a jacking lower disc, the cam continues to rotate to enable the transverse pressing block to transversely move to give way, the spring is released downwards at the moment when pressure is relieved, and jacking impact and aftershock are generated to shake off dust. According to the invention, the instantaneous release oscillation of the spring is combined with airflow blowing, so that the problems of dust floating pollution and secondary attachment caused by traditional pure airflow back blowing are effectively avoided, the dust cleaning is more thorough, the dust cleaning force can be flexibly adjusted by adjusting the size of the cam, and the practicability is high.

The utility model discloses a pulse back blowing industrial air purification dust collector, the utility model discloses a purification box body, and the purification box body upper end is fixedly connected with the top box through screw no.

The utility model discloses a valve cover and contain its electromagnetic pulse valve, the valve cover includes valve cover body, the upper surface of valve cover body has the exhaust pipe outside, the exhaust pipe is used for discharging the air of valve cover chamber of electromagnetic pulse valve, the bottom of exhaust pipe with valve cover chamber is linked together, and the top of exhaust pipe constructs and has the exhaust outlet, to export the compressed air in valve cover chamber. Through separating exhaust pipe and valve cover body, the exhaust pipe is external on valve cover body, thus, the section area of exhaust passage increases, and the angle of exhaust passage is reduced, and the exhaust resistance is reduced, can effectively promote the output pressure rising rate of electromagnetic pulse valve.

The utility model discloses a kind of water conservancy and hydropower engineering river channel governance sludge treatment equipment, belong to sludge processing technical field;Including: the bottom cylinder rotated by external power drive;The smashing cylinder shell fixedly installed in the upper position of bottom cylinder;Located in the smashing cylinder shell, the smashing cutter group fixedly assembled with the middle shaft of bottom cylinder;And, located in the lower position of smashing cutter group, the split screen is assembled in the smashing cylinder shell;The integral internal space is divided into: the upper sludge broken area and the lower discharge area by the split screen.The utility model, sludge is fully broken and handled, and not easy to block outside discharge;Multi-layer horizontal blade and vertical blade cooperate operation, and sludge is broken from different directions, further guarantee processing effect, and improve the strength of smashing cutter group, more reliable;Multiple primary screens are set by rotating switching frame, to avoid big sundries influence;With the setting of fender, avoid sundries spilled by screening, and cleaning operation is more convenient, more thorough.

The utility model provides a roller cone box assembling auxiliary device which comprises a square overturning frame formed by welding 100 mm channel steel and a supporting frame composed of two triangular supports and a cross beam, and bases of the triangular supports are fixed to a working face through foundation bolts. Fan-shaped rotating plates are symmetrically arranged below the two sides of the square overturning frame and synchronously rotate with a cone box rotating shaft through shaft holes, and the other end of the rotating shaft is connected to a bearing seat at the top of a triangular support through a spherical roller bearing. The driving mechanism is composed of a worm and gear assembly and a hand wheel, a worm gear is fixed to the extending end of the rotating shaft, and a worm mounting base is provided with a radial adjusting bolt to optimize the meshing clearance. According to the additional function design, 15-degree indexing locking holes in the edge of the fan-shaped rotating plate are matched with spring buckles for positioning; and an anti-skid rubber pad and a hand wheel anti-skid texture sleeve on the inner side of the overturning frame improve the operation stability. The device integrates rotation, transmission and positioning functions through a modular structure, and meets the precise rotation control requirement of the heavy cone box.
