The invention relates to a multi-pipe air inlet air mixing cabin which comprises a shell, an indoor air inlet pipe set, an outdoor air inlet pipe set and down draught preventing valve plates. An air mixing region and a mixed air outlet are formed in the shell, holes allowing indoor air inlet pipes and outdoor air inlet pipes to be inserted are formed in the shell, the indoor air inlet pipe set comprises the indoor air inlet pipes, the outdoor air inlet pipe set comprises the outdoor air inlet pipes, one end of each indoor air inlet pipe and one end of each outdoor air inlet pipe are arranged in the air mixing region, the other end of the corresponding indoor air inlet pipe and the other end of the corresponding outdoor air inlet pipe are arranged outside the shell, all the ends, in the air mixing region, of the indoor air inlet pipes and all the ends, in the air mixing region, of the outdoor air inlet pipes are provided with the down draught preventing valve plates, the down draught preventing valve plates are connected and fixed to the indoor air inlet pipes and the outdoor air inlet pipes through hinges, and the hinges are located in the centers of openings of the indoor air inlet pipes and the centers of openings of the outdoor air inlet pipes. Air inlet amount is disintegrated through multi-pipe air inlet, and control over air mixing proportions and air mixing temperature is facilitated; the problems of air leakage and down draught can be solved through the tiny air inlets and the down draught preventing valve plates.

The invention relates to the field of processing of road asphalt concrete and discloses cold recycling equipment for road asphalt concrete. The cold recycling equipment comprises a storage mechanism of waste asphalt concrete, a water storage mechanism, a cement storage mechanism, a foamed asphalt storage mechanism, a mixing box and a collecting box, wherein the foamed asphalt storage mechanism comprises a heating tank and a foaming mechanism; the foaming mechanism comprises a pipe body which comprises an entering section, a mixing section and a discharging section from top to bottom; the mixing section comprises a water pipe communicated to the water storage mechanism, a water pump is mounted on the water pipe, the water pipe is of an L-shaped structure, the vertical section of the water pipe and the axis of a first liquid pipe are located on the same straight line, a mixing platform is slidably connected to the outer side of the water pipe, and the end part of the mixing platform is slidably connected to the side wall of the entering section. The constant temperature water enters the asphalt and the contact time of the constant temperature water and the asphalt is prolonged, so that the foaming rate of the asphalt is improved.

The invention provides a proportional feed mixing equipment for construction engineering, comprising: a base, a mixing tank and a water inlet; a group of mixing tanks is fixedly connected to the top of the base; a group of mixing tanks is fixedly connected to the inner central axis of the mixing tank The stirring shaft; the right end face of the mixing bucket is fixedly connected with a group of the gearbox; the power input shaft of the gearbox is fixedly connected with a group of the hybrid motor; the power output shaft of the gearbox A set of stirring shafts is fixedly connected coaxially; a set of mixing outlets is provided on the left lower end surface of the mixing barrel. The mixing effect and mixing efficiency are improved by adopting the spiral blade-like mixing blade and the fixed mixing paddle; by setting two sets of reclaiming wheels and adjusting the reclaiming speed through the speed of the retrieving wheels, the mixing ratio can be controlled accurately, and the mixing ratio can be precisely controlled and further improved. The material is uniform and prevents the uneven mixing caused by the accumulation of materials.

The invention discloses a single-side ventilation device for forming the airflow organization of an air pool and a control method thereof. Round; the two vertical planes of the ventilation duct are respectively parallel to the two walls at the corner of the room where it is installed; the air supply port at the top of the ventilation duct is connected to an external air supply device; the top of the room is also provided with an exhaust device , the exhaust device communicates with the room. The device of the present invention reduces the amount of mixing with indoor polluted air or hot air, and improves the quality of the air supply; the formed cold air pool has a wider coverage, and uses the air supply port and the two side walls of the corner to form a double-sided attached jet The unique air supply method can maximize the effect on the entire work area, thus ensuring the freshness of the air in all work areas, so that the air quality and temperature and humidity in the work area can meet the comfort requirements.

The invention discloses a piston ring manufacturing equipment, the structure of which comprises a raw material box, a hinge, a box door, a ring outlet, a supporting foot, a manufacturing host, and an operation panel. The front surface is connected, and the left end of the ring outlet is installed on the lower right end of the manufacturing machine by embedding. The flow of raw materials is controlled by a solenoid valve, and the mixing ratio of raw materials can be accurately controlled, and then the raw materials are filtered and screened by the screening mechanism. The materials are excluded to make the raw materials more delicate, so that the manufactured piston rings are more detailed, and then the raw materials are heated and stirred by the stirring mechanism to make the stirring more sufficient, and then the materials are pushed into the heat setting mechanism by the booster mechanism to shape the piston ring , the shape stability of the piston ring can be improved by heat setting, and the piston ring will then be stronger and more stable.
