A household range hood comprises a range hood body, an oil collecting box is detachably mounted at the bottom end of the range hood body, a bottom plate and an oil collecting groove are arranged at the bottom of the oil collecting box, and the oil collecting groove is obliquely formed above the bottom plate; an interlayer and a heating assembly mounted in the interlayer are arranged between the bottom plate and the oil collecting groove; an oil stain cleaning mechanism is arranged at the high end of the oil collecting tank; and an oil stain inflow cover is arranged at the lower end of the oil collecting groove, is of a funnel structure and is detachably connected with an oil stain storage tank. According to the household range hood disclosed by the utility model, through the arrangement of the heating assembly and the oil stain cleaning mechanism, oil in the oil collecting groove is softened firstly, and then the softened and cleaned oil stain flows to the lower part along the inclined oil collecting groove in cooperation with spraying of an oil stain cleaning agent and flows into the oil stain storage tank through the inflow port at the upper end of the oil stain inflow cover; the oil collecting box is regularly cleaned, and bacteria breeding caused by the fact that oil stains are more and more viscous and cannot be treated due to long-time accumulation is avoided.

The invention discloses a treatment system for synergistically removing odor substances and a new pollutant PFAS in water and a treatment method thereof. The treatment system comprises a pre-oxidation unit, an algae removal, adsorption and clarification unit, a membrane separation and concentration unit and a destruction unit which are connected in sequence. The pre-oxidation unit is provided with an oxidation pond with a transverse reciprocating dynamic aeration assembly, so that the ozone mass transfer efficiency is improved. The algae removal, adsorption and clarification unit enables a suspended carbon mud bed to periodically expand and contract through a pulse generator so as to strengthen adsorption. The membrane separation and concentration unit adopts a modified polyether sulfone conical-end filtering membrane and is matched with an online cleaning mechanism, so that PFAS is efficiently intercepted, and secondary pollution is avoided. The destroying unit is used for carrying out synergetic high-temperature incineration on the membrane separation concentrated water and the waste carbon mud, and PFAS is thoroughly decomposed at the temperature higher than or equal to 900 DEG C; by optimizing ozone aeration, pulse adsorption, fluorine-free membrane separation and collaborative incineration, efficient collaborative removal of odor substances and new pollutant PFAS and harmless treatment of waste are achieved, the system integration degree is high, the treatment effect is good, and the risk of secondary pollution is avoided.

This utility model relates to a thread grinding machine, including a base, a chuck and a tailstock for clamping workpieces, and a horizontally movable wheel frame. A grinding wheel spindle and a drive motor are mounted on the wheel frame. A material discharge hole is formed on the upper surface of the base between the chuck and the tailstock. A funnel-shaped material collection bin with openings at both the top and bottom is installed at the bottom of the material discharge hole. A cleaning brush adapted to the inner wall of the material collection bin is installed inside the bin. The cleaning brush is connected to the base via a horizontal slide, and one end of the cleaning brush is connected to the wheel frame. The cleaning brush moves synchronously with the wheel frame, cleaning debris adhering to the inner wall of the material collection bin. This utility model, by providing a material discharge hole on the base and installing a funnel-shaped material collection bin, utilizes the horizontal movement of the wheel frame to drive the synchronous movement of the cleaning brush, achieving periodic cleaning of the inner wall of the material collection bin, effectively avoiding equipment failure and reduced machining accuracy caused by debris accumulation.
