6results about How to "Reduce screening efficiency" patented technology

This utility model discloses a sand and gravel separator, specifically relating to the field of concrete production technology. It includes a collection box with an auger conveyor installed on one side. The bottom of the auger conveyor is connected to a discharge port. A screening machine is installed at the top of the collection box, with a feed port connected to its top. A cleaning component is installed inside the screening machine, and a feeding mechanism is installed inside the discharge port. The cleaning component includes a baffle plate fixedly connected to the inside of the screening machine. A first filter screen and a second filter screen are fixedly connected inside the screening machine by screws, with the second filter screen installed on one side of the first filter screen. By setting up the cleaning component and the feeding mechanism, this utility model allows for dual screening of sand and gravel by the first and second filter screens, effectively cleaning their surfaces, reducing clogging and improving screening efficiency, maintaining good separation performance, and minimizing sand and gravel accumulation and compaction inside the discharge port, ensuring smooth discharge of sand and gravel.

The utility model discloses a shavings screening machine for shaving board processing relates to shaving board processing technical field, including frame, spring, sieve, sieve plate, sieve pore and vibrating machine. The utility model discloses the cooperation of frame, spring, sieve, sieve plate, sieve pore, vibrating machine, prevent blocking device, turn over subassembly, rubber boss, drive belt and the sheath of using, the solution existing linear vibrating screen, since the shavings are mostly the flaky structure with certain puffy, its movement in the sieve mainly depends on the overall vibration of sieve, and the upper shavings are easily accumulated with the buffer and have poor mobility, and it is difficult to be fully shaken by sieve plate, leading to this part of shavings mobility can not be effectively screened, further influence screening effect, simultaneously, the edge of flaky shavings is easy to be stuck in sieve pore, in addition, the continuous extrusion of shavings to sieve pore in the vibration process, sieve pore is easily caused to be blocked, not only needs frequent shutdown cleaning for a period of time, also reduced screening efficiency.

The utility model provides efficient Chinese wolfberry impurity screening and separating equipment, and relates to the technical field of Chinese wolfberry separating equipment, the efficient Chinese wolfberry impurity screening and separating equipment comprises a screening box, the lower end face of the screening box is fixedly provided with four walking wheels, the right side of the upper end face of the screening box is provided with a feeding port, and the lower portion of a left side plate of the screening box is provided with a discharging plate. Firstly, an air suction pipe on the surface of a partition plate is externally connected with a fan, the air suction range is enlarged through an umbrella-shaped structure at the lower end of the air suction pipe, light impurities such as leaves are sucked out of a screening box, and meanwhile, a filter plate achieves separation of the Chinese wolfberry and small impurities through filter holes in the surface of the filter plate; the problems that existing screening equipment still has defects in the screening effect, the speed of the Chinese wolfberries entering a screening box cannot be controlled, and if the Chinese wolfberries contain many impurities and the speed of the Chinese wolfberries entering the screening box is high, the impurities in the Chinese wolfberries cannot be cleaned up are solved.

The utility model discloses a kind of screening treatment equipment for diatomite raw soil, including machine body, screen cylinder and sieve hole, the screen cylinder is set on the machine body upper end, and with the machine body movable connection, the number of sieve hole is several, and evenly set in the screen cylinder one week surface.The utility model is through the cooperation of machine body, screen cylinder, sieve hole, percussion assembly, rotating seat, beat plate, tension spring, extruding piece, fixed seat, extruding block, cleaning brush component, fixed plate, brush strip, rubber boss and support frame, to some extent, improve or solve the existing screen cylinder screening machine when using, since diatomite has certain viscosity and has not screened impurity, it is easy to adhere on sieve hole in screening process, leading to the blockage of part sieve hole, not only can reduce screening efficiency, make production speed slow down greatly, and need artificial frequent shutdown cleaning sieve hole, increase the problem of labor intensity.

The utility model relates to the technical field of mortar preparation, in particular to a vibrating screen for mortar preparation, which comprises a vibrating screen box and two fixing seats, two screen meshes are arranged in the vibrating screen box, and a plurality of mounting plates are arranged in the vibrating screen box; a convex shell is fixedly connected to one side of the mounting plate, and a sliding rod is fixedly connected to the interior of the convex shell; the vibrating screen has the advantages that the bottom of the screen mesh can be knocked through the knocking hammer when the vibrating screen works, the problem that when the screen mesh is blocked during working of the vibrating screen, manual shutdown is needed to clean the blocked screen mesh is solved, the working efficiency of the vibrating screen is improved, and the labor intensity of workers is reduced. And meanwhile, the crushing plate is matched with the vibrating screen to work to crush the caked materials on the screen, the effect of avoiding material waste and cost increase is achieved, the problem that when the vibrating screen works, the caked materials cannot be normally screened, and consequently the materials are wasted is solved, and the practical performance of the vibrating screen is improved.

The utility model belongs to drying equipment technical field, concretely relates to a device that controls powder drying, including the heating cylinder of area heating function, the top right side feed inlet department of heating cylinder is fixedly connected with the feed hopper, the right end middle part of heating cylinder is fixedly connected with drive motor, and the output shaft of drive motor extends to the inside of heating cylinder. The device that controls powder drying of the utility model, the powder that needs drying enters through the feed hopper, and then makes the screw hinge dragon rotation that sets up internally through drive motor drive, so that first sprocket drives second sprocket clockwise rotation through chain, and cooperate with the meshing of two gear, further make two rubbing rollers relative rotation, and carry out rubbing to the powder falling between two guide plates, and the powder of agglomeration falls on the screen together after rubbing, and the rotation of gear, still drive transmission column rotation, and cooperate with the setting of transmission channel and Z type rod, further cooperate the effect of connecting rod, make the screen in the discharge port move back and forth.
