The application relates to the technical field of low-voltage electrical apparatus, in particular to a circuit breaker, which comprises a protective shell, an arc extinguishing assembly, a moving contact for connecting an anode and a static contact for connecting a cathode; an arc extinguishing chamber is formed in the protective shell, the arc extinguishing chamber is divided into a first region and a second region; the first region is close to a tripping position of the moving contact, and the second region is close to the static contact; the arc extinguishing assembly comprises a first group of arc extinguishing fins arranged in the first region and a second group of arc extinguishing fins arranged in the second region; the number of the first group of arc extinguishing fins is less than that of the second group of arc extinguishing fins; when in the tripping position, an electric arc at the moving contact is transferred to the first group of arc extinguishing fins. The application optimizes the structure of the first group of arc extinguishing fins by improving the transfer efficiency of the electric arc on the moving contact, thereby effectively enhancing the utilization rate of the arc extinguishing fins.

The utility model discloses a kind of anti-blocking plastic particle raw material mixing devices, it is related to plastic particle production field, its technical solution main point is: including the columnar mixing tank of top opening, the upper portion of the mixing tank is provided with lifting platform driven by reciprocating mechanism, so that lifting platform can be under the action of reciprocating mechanism along the small amplitude lifting motion of mixing tank vertical direction, the top of lifting platform is provided with power device for driving the rotation of stirring paddle located below it, feeding assembly is also installed on lifting platform, effect is through reciprocating mechanism driving lifting platform along the small amplitude lifting motion of mixing tank vertical direction, to drive the small amplitude up-down movement of stirring paddle and feeding assembly, when encountering plastic particle of larger viscosity or easy to cake, the small amplitude up-down movement of stirring paddle can increase the impact force and shear force to these particles, to avoid the blockage of stirring cavity due to particle accumulation.

The application discloses a kind of production device of recycled asphalt mixture and preparation method thereof, it is related to asphalt production equipment technical field, including mixing tank, feeding assembly, feeding port, storage tank and liquid conveying assembly;Mixing tank is equipped with stirring assembly with stirring shaft and spray pipe, and is equipped with discharge pipe at bottom;Feeding assembly includes conveying cylinder, screw conveying piece and reciprocating slideable sliding cylinder and feeding pipe;Feeding port is equipped with radially extending feed opening, and both sides inclined baffle strip forms gradually narrowing feeding opening from outside to inside.Working time, feeding pipe reciprocating sweep cooperation radial gradient feeding makes material feeding quantity and stirring intensity adaptation, solid-liquid component synchronous mixing.The application can avoid material accumulation in weak stirring zone, improve mixing uniformity and mixing efficiency, realize multi-component accurate proportioning and continuous production, improve the road performance of recycled asphalt mixture, and is suitable for efficient recycling of waste asphalt pavement material.

The invention discloses degradable small-leaf broadleaf holly leaf antibacterial wet toilet paper and a preparation method thereof.The wet toilet paper comprises a fiber paper base material capable of being dispersed and degraded and functional liquid medicine evenly loaded on the fiber paper base material, the functional liquid medicine only contains a small-leaf broadleaf holly leaf extract with the concentration being 12.5-25 mg / mL and purified water, the water content of the product is controlled to range from 60% to 65%, and the water content of the product is controlled to range from 20% to 30%. The antibacterial rate on various common pathogenic bacteria is greater than or equal to 95%, the pH value is 5.5-6.5, and the antibacterial agent is mild and non-irritant; according to the preparation method, the high-activity small-leaf broadleaf holly leaf extract is prepared through a specific process, a base material is subjected to accurate soaking and extrusion dehydration by adopting optimized liquid-paper ratio, temperature and time parameters, then folding and slitting are performed, and finally strict sterile packaging is performed, so that the high-activity small-leaf broadleaf holly leaf extract is obtained. Therefore, the environment-friendly wet toilet paper product which is natural and pure in component, good in antibacterial effect, safe and comfortable to use and biodegradable is obtained.
