3results about How to "Solve uneven distribution" patented technology

The utility model discloses injection molding machine waste gas collecting device, including main body frame, shaking mechanism, flow regulating mechanism and adjusting auxiliary mechanism, the shaking mechanism includes processing jar, drive motor, support axle, connecting hose and adding pipe, the flow regulating mechanism includes adjusting pipe, inner rotary frame, threaded rod, thread bush, moving frame, layer whirlpool board and inner fixed frame, make processing jar do regular shaking movement through drive motor drive support axle, effectively solved the problem of uneven distribution of waste gas in traditional device, and this dynamic shaking design promotes the full mixing contact of waste gas and auxiliary agent, eliminates the airflow dead angle and stratification phenomenon in processing jar, adopts the accurate transmission design of threaded rod and thread bush, drives moving frame to do linear motion through the rotation of inner rotary frame, makes the clearance between layer whirlpool board and inner fixed frame accurate and adjustable, and this design solves the problem that the waste gas flow of traditional device is difficult to accurately regulate.

This invention discloses a spray air intake device for a tubular PECVD equipment, comprising a reaction chamber, and an air intake spray plate, a graphite boat, and an exhaust plate disposed within the reaction chamber. The air intake spray plate and the exhaust plate are respectively installed above and below the graphite boat, or respectively installed below and above the graphite boat. The air intake end of the air intake spray plate extends to the outside of the furnace opening and the outside of the furnace tail of the reaction chamber. The front end of the reaction chamber is provided with a furnace door flange, and the rear end of the reaction chamber is provided with a furnace tail flange, which has multiple exhaust ports. During the process, the process gas is transported into the reaction chamber through the air intake spray plate, flows downward through the graphite boat, enters the exhaust plate, and is finally discharged through the exhaust ports on the furnace tail flange. This invention features a compact structure, convenient operation, high safety, and high gas distribution uniformity, effectively reducing the waste of process gas.

This application relates to the technical field of precast concrete curing equipment, and discloses a temperature- and humidity-adjustable precast concrete temperature-controlled curing box, including a support ring plate. A curing box is fixedly connected to the upper surface of the support ring plate, and a support block is fixedly connected to the side of the curing box. A servo motor is fixedly connected to the upper surface of the support block, and a threaded rod is fixedly connected to the output end of the servo motor. An internal threaded cylinder is threadedly connected to the surface of the threaded rod, and a movable plate is fixedly sleeved on the surface of the internal threaded cylinder. The operation of the servo motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the movable plate to move through the internal threaded cylinder. The movement of the movable plate drives the second annular tube and the first annular tube to move respectively. When the second annular tube moves to the leftmost position, the servo motor drives the movable plate to move again through the internal threaded cylinder. The movement of the movable plate then drives the second annular tube and the first annular tube to move in opposite directions, which solves the problem of uneven steam distribution to a certain extent.
