This application relates to the technical field of potato processing equipment, and more specifically, to a potato impurity removal and pulping device. In the potato impurity removal and pulping device provided in this application embodiment, a vertical rotating shaft drives a fan-shaped spreading plate to evenly spread the pulp into a thin layer on the upper surface of a circular screen plate. Combined with the directional cleaning function of a synchronously rotating brush, impurities can move synchronously circumferentially with the brush, preventing them from accumulating on the circular screen plate and clogging the screen holes. Using the above structural design, by integrating a rotating impurity removal mechanism below the crushing chamber, continuous crushing and impurity removal operations are achieved. Furthermore, the crushing and impurity removal operations can be carried out continuously without interruption, and there is no need to stop the machine to clean the circular screen plate during this process, thereby greatly improving the potato pulping efficiency.

The invention discloses a rotary kiln discharge screening device, which is used for coarse and fine screening of discharge materials of a rotary kiln, and comprises a conical screen structure rotating around the horizontal center line of a movable cylinder, and a fine material discharge port and a coarse material discharge port which are arranged at the lower part of a static cylinder; the conical screen structure is arranged on the outer side of the annular plate on the outer side of the movable cylinder, when the rotary kiln runs, the conical screen rotates around the horizontal center line of the movable cylinder, and dynamic screening of discharging materials of the rotary kiln is achieved; the conical screen spiral blades are intermittently welded to the inner side of the conical screen, so that fine materials discharged by the rotary kiln are evenly screened out at the fan ring opening of the conical screen, and coarse materials discharged by the rotary kiln are smoothly and stably screened out at an outlet in the right portion of the conical screen; through the special structural design of the fan ring base plate of the conical screen, the change of the shape of the cross section of the screen is kept continuous, the thermal stress concentration area is reduced, meanwhile, thermal expansion displacement is fully considered in the design of the screen, and long-time stable screening of discharged materials of the rotary kiln at the high temperature of 1050 DEG C is achieved.

The utility model discloses an atomizing spray head, which comprises a sleeve and a spray head, the top of the sleeve is communicated with a connecting pipe, the spray head is in threaded connection with one end, far away from the connecting pipe, of the sleeve through a threaded piece, a filter screen is detachably connected in the connecting pipe, a dredging assembly is arranged in the sleeve, and the dredging assembly can dredge the water flow flowing into the connecting pipe. When the flow rate of the adjusted water flow is small, a spring rebounds to drive a fixing plate to move towards one end close to the filter screen, and a round plate is driven to approach the filter screen through a fixing rod while the fixing plate moves; impurities and particulate matters blocked in the meshes of the filter screen are ejected out through the ejector pin, so that the meshes of the filter screen are dredged, the impurities and particulate matters blocked in the meshes can be dredged by adjusting the water flow, the operation is relatively convenient, and the problem that a spray head needs to be disassembled and assembled for cleaning and dredging during blockage is avoided.

The utility model provides a grading screening machine for low-carbon ferrochrome products, which belongs to the technical field of low-carbon ferrochrome production and comprises a material storage component, a support, a frame fixedly mounted in the middle of the support and a material collecting box mounted in the middle of the frame. The screening assembly comprises a supporting piece fixedly installed at the upper end of the frame body, a connecting piece connected to the upper end of the supporting piece in a threaded mode, a screening box rotationally installed on the side wall of the connecting piece, a screening plate fixedly connected to the inner side of the screening box and a feeding frame connected to the middle position of the end of the screening box in an inserted mode. The low-carbon ferro-chrome screening device has the advantages that the storage assembly and the screening assembly are used in cooperation, so that materials on the screening plate move sufficiently, the problems of material accumulation and screening hole blocking are avoided, the screening efficiency is improved, low-carbon ferro-chrome products with different particle sizes can be rapidly and accurately separated, the screening box can be conveniently adjusted and maintained, and the screening efficiency is improved. And the continuity and the stability of the whole screening process are ensured.

The invention discloses equipment for agricultural non-point source pollution control, which comprises a box body, a sieve plate is assembled at one end in the box body, a mixing box is assembled at the top of the other end in the box body, a connecting shaft extending into the box body is assembled at the bottom of the mixing box, and a spraying rod is assembled at the periphery of the connecting shaft; a cleaning mechanism is slidably arranged on the side, away from the connecting shaft, of the screen plate, and collecting mechanisms are arranged on the two sides of the screen plate. Through cooperation of the cleaning mechanism and the collecting mechanism, in the using process, when a scraper carries out movable cleaning work on a screen plate, agricultural films and other impurities on the screen plate can be pushed by the scraper to one side of the screen plate, then after the scraper moves to the position of a collecting box, an extension rod can be pushed to move in the direction of a through groove, and then a blocking plate moves into the through groove; and the agricultural film and other impurities are pushed to enter the collecting box and then move into the collecting box to be collected under the action of water flow.
