The utility model can make fuel and air (or oxygen) meet in air inlet passage and mix and spiral input to annular gas cavity along guide groove, realize better premixing effect.

The utility model provides a kind of mixed material flow guide sorting device, including the inclined rod being arranged with the conveying direction of conveying belt certain angle, two ends of inclined rod are connected with support rod respectively, and the bottom end of support rod is fixedly connected on support surface, multiple flow guides are fixed below the area corresponding to conveying mechanism of inclined rod, and any two adjacent flow guides are parallel and have same interval;The connecting line formed by the gravity center of multiple flow guides is parallel to inclined rod, and the board surface of flow guide is parallel to the conveying direction of conveying belt, and the direct discharge into waste bin by flow guide sorting is achieved to the off-falling lining plate and other larger blockiness impurities, to avoid the impurities into kiln head material bin to cause plugging.

This utility model relates to the field of facial mask liquid production technology, specifically a mixing device for facial mask liquid production. It includes a hopper and an injection pipe. A stirring mechanism is installed inside the hopper, and a retaining element is installed at its upper part to initially retain the facial mask liquid entering from the injection pipe in a storage area. A pre-stirring rod is installed on the stirring mechanism to pre-mix a small amount of facial mask liquid in the storage area. As the amount of facial mask liquid injected into the storage area increases, the pre-mixed facial mask liquid overflows from the retaining element into the stirring area. This utility model, with its retaining element, pre-stirring rod, and storage area, allows for a smaller amount of facial mask liquid injected into the storage area. The pre-stirring rod can pre-stir to achieve high mixing effect and efficiency. When the facial mask liquid overflows from the storage area into the stirring area, the stirring mechanism can perform a secondary overall stirring of the pre-mixed facial mask liquid concentrated in the stirring area, further ensuring mixing uniformity. Furthermore, because the individual pre-mixing and overall stirring are continuous, the mixing efficiency is also improved.

The utility model provides a kind of raw material premixing anti-settling device, it is related to foaming agent production technical field, and it includes: mixing tank;The lower part of the mixing tank is fixedly connected with multiple groups of support rods in annular array shape;The top surface of mixing tank is provided with cover plate;The top surface of cover plate is bolted and fixedly connected with driving motor;Driving motor rotating shaft lower part is coaxially fixedly connected with transmission rotating shaft;The lower part of transmission rotating shaft is fixedly connected with anchor type paddle.When the situation of instantaneous feeding amount is too large appears, the impact force of raw material to baffle increases momentarily at this time, makes control baffle to turn down, then makes resistance material baffle to turn up by a series of transmission, channel flow cross section reduces in turn, directly limit raw material passing speed, solved the problem that when a large amount of raw material is poured into feed hopper at a time, it is easy to cause instantaneous feeding amount to be larger due to the action of gravity, excessive raw material surges into mixing tank in short time, makes the local raw material concentration in mixing tank too high.

This utility model discloses a low-NOx gas burner, including a burner shell and a burner head disposed at the front end of the burner shell. One end of the burner head has an air inlet, and a premixer is disposed inside the burner head. The premixer includes a first sleeve and a second sleeve arranged coaxially in a ring, forming a premixing chamber. Several swirl blades are evenly distributed along the center of the outer side of the first sleeve near the air inlet. This utility model avoids gas diffusion and leakage during premixing by placing the premixer inside the burner head. Furthermore, the premixing chambers one and two of the premixer perform dual premixing of the gas and combustion air. The swirl blades one and two are arranged in opposite directions, causing bidirectional rotation and agitation between the combustion air and the gas, resulting in more uniform premixing and more complete combustion, thereby reducing the content of nitrogen oxides.
