2results about How to "Normal work does not affect" patented technology

The utility model discloses a lathe cutting fluid spraying device which comprises a main body, a spraying mechanism and a spraying head switching mechanism, the main body comprises a box body and a lathe machining table fixedly installed on the inner wall of the box body, and a lathe driving box is fixedly installed at the upper end of the lathe machining table; the lathe machining device has the beneficial effects that the gear motor and the driving gear drive the movable toothed plate to move, the movable toothed plate, the fixing plate, the T-shaped connecting plate and the electric push rod are arranged to drive the mounting plate to move, the position of the spraying head is adjusted, and the spraying head can be conveniently and rapidly mounted. According to the spraying assembly, the spraying heads of different models can be switched to adapt to machining of parts of different specifications, and due to the fact that each set of spraying heads is symmetrically provided with two spraying heads, when one spraying head is blocked or damaged, the other spraying head of the same model can be rapidly started, normal work of the spraying assembly is guaranteed, and normal proceeding of cutting machining is not affected.

This invention discloses a HVAC duct filter and cleaner, belonging to the technical field of HVAC duct components. It includes an oblique tee, a stainless steel filter screen, a sealing base, a cleaning valve, and a drain pipe assembly. The oblique tee has a neck on its inner side; a retaining edge is provided near the input end of the neck; the stainless steel filter screen has a cylindrical structure, with one end installed to the neck and the other end fitting against the retaining edge; the other end of the stainless steel filter screen connects to the inclined end of the oblique tee; the sealing base includes a pipe seat body screwed to the inclined end of the oblique tee, and the front end of the pipe seat body is integrally formed with a guide ring seat that fits against the inner wall of the stainless steel filter screen; the stainless steel filter screen fits against the end of the pipe seat body; the cleaning valve includes a cavity seat screwed to the lower end of the pipe seat body. This HVAC duct filter and cleaner uses flow pressure to achieve online cleaning of the stainless steel filter screen, and the discharge of impurities from the flow medium will not affect the normal operation of the HVAC system.
