[Problem] To improve dust collecting efficiency while reducing the pressure loss of a cyclone. [Solution] This cyclone 1 comprises: an outer cylinder 3 provided at the upper part of a revolving cylinder 2 and expanded in diameter downward; an inner cylinder 4 concentrically provided in the outer cylinder 3; a conical part 9 provided at the lower end of the outer cylinder 3 and contracted in diameter downward; a flow straightening member 5 which is provided in the space directly below the inner cylinder 4 and in which a plurality of planar flow straightening plates, each having a curved surface formed in at least the lower half thereof, is provided at equal angular intervals around the axis of the inner cylinder 4, the curved surface of each planar flow straightening plate being oriented in a direction opposite to the swirling flow flowing around the inner periphery of the inner cylinder 4; an inflow cylinder 6 provided in the tangential direction to the outer periphery of the outer cylinder 3; and a drop port 8 provided at the lower part of the revolving cylinder 2. An inner diameter D2 of the lower end of the outer cylinder 3 can be 1.1-2.2 times an inner diameter D1 of the upper end of the outer cylinder 3. The height of the outer cylinder 3 can be 0.8-1.6 times the inner diameter D1 of the upper end of the outer cylinder 3.

This utility model relates to the field of ball screw machining technology and discloses an adjustable ball screw cyclone milling fixing device, including a machine tool. The machine tool is equipped with a milling assembly for milling workpieces. A tray is fixedly connected to the worktable of the machine tool. A support platform is provided on the tray via a transverse component. Two symmetrical T-shaped guide rails are fixedly connected to the upper surface of the support platform. Two symmetrical slides are slidably connected to the two T-shaped guide rails. A fixing frame is fixedly connected to each of the two slides. Three-jaw chucks for clamping workpieces are rotatably connected to the opposite sides of the two fixing frames via bearings. This utility model can fix workpieces of different lengths by changing the position of the two three-jaw chucks, effectively fixing workpieces of various lengths from very short to quite long, without replacing the entire fixture or making complex resets. The structure is simple and easy to operate.

The optimized condenser is an indirect evaporative cooling system with a mechanism of placing the water film in the vicinity of the combined air directed on one side of the metal surface of the main cooling elements against the impact of the target air perpendicular to the other side of the surface of the said elements and the optimal direction of the target air flow in a venturi shape. This condenser has a weather diffuser in the upper area of the condenser that has valves that are equipped with A sprinkler nozzle consists of a body whose target air outlet is smaller than the target air intake opening. Inside the condenser, there are three types of cooling elements in the form of air passage profiles, the main elements have a curvature against the target airflow and a vertex behind the stream to avoid tornadoes, which are arranged horizontally and crosswise and on both sides of the wall The condenser, angled cooling elements resemble a staircase, and in the funnel area of the condenser body, there are cubic cooling elements. The cooling fins are also located in the form of floors with a small distance, in which the inlet air of the target is divergent and convergent and the side currents of the main axis are all distributed horizontally and vertically, and when colliding with the curved part of the main profiles that have a water film from the inside, the cooling action is performed.

The utility model belongs to the technical field of waste material conveying devices, and particularly relates to a waste material conveying device for a numerical control whirlwind milling machine tool, which comprises a support frame, two first rollers, a plurality of second rollers and a plurality of second rollers, the conveying belt is wound on the two first rollers to form a closed-loop structure; when any first roller rotates, the conveying belt moves along with the first roller, so that the other first roller is driven to rotate, and continuous conveying of waste materials is achieved. The two rubber strips are symmetrically arranged on the two sides of the conveying belt in a winding mode, the rubber strips are connected end to end so as to limit waste on the conveying belt, and the waste conveying device for the numerical control whirlwind milling machine effectively limits the moving range of the waste and prevents the waste from falling off from the two sides of the conveying belt by introducing the rubber strips.
