The utility model belongs to the field of ore dressing relates to a kind of flotation machine ore separation box, including T-shaped partition, the T-shaped partition is installed in the ore separation box, and the ore separation box is divided into two parts of feed tank and distribution tank;The T-shaped partition includes vertical plate perpendicular to the bottom surface of the ore separation box and horizontal plate parallel to the bottom surface of the ore separation box and fixed on the top of the vertical plate;The length of the vertical plate is equivalent to the length of the ore separation box, the height of the vertical plate is not more than 1 / 2 of the height of the ore separation box;The length of the horizontal plate is equivalent to the length of the ore separation box.The technical scheme of the application can delay the flow rate of ore pulp, which is beneficial to uniform ore separation and improves the flotation effect;At the same time, the ore can be ground, and the bottom plate after modification will not be impacted by the ore pulp.

The utility model relates to the technical field of anti -wear D type ring, concretely is a kind of anti -wear D type ring device, including D type ring main body, be provided with anti -wear structure on D type ring main body, first protective shell is fixedly installed with multiple fixed frame of cooperation with connecting block, fixed frame and connecting block are all set with connecting hole, recess is set in the inside of connecting hole set in connecting block, first plug rod is movably installed in the inside of connecting hole, the one end of first plug rod is fixedly installed with clavus, the utility model is set through the setting of anti -wear structure, changes the mode for improving the wear resistance of D type ring main body by coating wear -resistant material on traditional D type ring main body, so that the wear -resistant mode of D type ring main body cannot be influenced by environment, the advantage of this structure is in that D type ring main body can be under the condition of good wear resistance, still cannot be influenced by environment, and this structure is not frequently replaced, so its maintenance and difficulty will be greatly reduced.

The commercial multifunctional integrated smoke hood for the canteen comprises an upper machine box and a lower machine box, a fan shell is installed in the upper machine box, a lifting block is fixedly connected to the surface of the rear side of the lower machine box, the lifting block is connected into a lifting groove in a sliding mode, the lifting groove is formed in the surface of a fixing structure, and the fixing structure is arranged in the lifting groove. The fixing structure is fixedly mounted in a wall surface through a mounting block, a driving motor is fixedly mounted at the upper end of the fixing structure, the output end of the driving motor is in transmission connection with a threaded screw rod, the surface of the threaded screw rod is in threaded connection with a lifting block, and a telescopic oil smoke pipe is mounted in the upper case in a penetrating manner; by means of the lifting groove and other structures, during use, the control panel controls the driving motor to drive the threaded lead screw to rotate, so that the lifting block ascends or descends in the lifting groove, and finally the upper case and the lower case are driven to move up and down so as to be suitable for users of different heights to use.

The present invention discloses a drilling tool for machining large workpieces, and relates to the technical field of machining tools, including a tool head, the top end of which is rotatably connected to a protective mechanism; the tool head includes a tool bar, the top end of which is rotatably connected to the inner wall of the protective mechanism, the protective mechanism includes a rotating sleeve, the rotation of which is connected to the outer wall of the tool bar, the top end of which is fixedly connected to a connector, and the inner wall of which is fixedly connected to a transmission rod. The present invention enables the protrusion to be pushed by the inclined groove when subjected to a large rotation resistance, so that the rotating seat moves upward, thereby compressing the pressure spring, so that the rotation force of the transmission rod cannot be transmitted to the tool bar, thereby preventing the side reaming tool and the main drilling tool from being forced to rotate when subjected to excessive resistance during hole opening, causing serious damage to the side reaming tool and the main drilling tool, thereby increasing the service life of the tool, reducing the use cost of the tool, and avoiding the tool from being stuck inside the workpiece when opening.

The invention discloses a digital sponge city rainwater collection and utilization device and an optimization method thereof, and belongs to the technical field of rainwater collection and utilization, the digital sponge city rainwater collection and utilization device and the optimization method thereof comprise a primary filtering assembly, a gravity assembly is arranged below the primary filtering assembly, and the gravity assembly is arranged below the primary filtering assembly; the gravity assembly can slide according to different weights of accumulated water in the primary filtering assembly; a rotatable flow stopping assembly is arranged below the gravity assembly, and a water storage assembly is arranged below the flow stopping assembly; one side of the water storage assembly is rotationally connected with a water diversion assembly, and the water diversion assembly can slide to be opened and closed. According to the rainwater collection device, rainwater collection can be conducted under the specified condition through the elastic force of the spring, only when the rainfall is too large, the rainwater can flow into the barrel body after water in the funnel reaches the specified weight, and therefore unnecessary rainwater collection can be prevented when the rainfall is small.
