The utility model belongs to the technical field of peanut oil processing, and particularly relates to a filtering device for peanut oil processing, which comprises a filtering charging barrel, the top of the filtering charging barrel is fixedly connected with a top cover, a grading filtering assembly is arranged in the filtering charging barrel, the grading filtering assembly comprises three filtering discs and a sealing rubber strip, and the sealing rubber strip is arranged in the filtering charging barrel. According to the peanut oil filtering device, peanut oil is filtered for multiple times through the three filtering discs which are distributed in a step shape from top to bottom, and the mesh number of the filtering holes in the bottoms of the three filtering discs is gradually increased, so that the effects of filtering the peanut oil step by step and separating material residues are achieved; the driving box is started to control the three oil pressing plates to move downwards on the inner sides of the three filtering discs, so that the oil pressing plates extrude material residues filtered out by the filtering nets at the bottoms of the filtering discs from the upper side, full utilization of the material residues is facilitated, and the filtering effect on peanut oil is improved.

The invention provides a foaming device and method for bubble mixed light soil production, and relates to the technical field of foaming devices.The foaming device for bubble mixed light soil production comprises a supporting table, and a machining pipeline is fixedly installed in the supporting table; a discharging assembly used for receiving and discharging materials is fixedly installed at the upper end of the processing pipeline, and a set of mixing assemblies used for improving contact between the materials and gas are arranged in the processing pipeline. A discharge threaded blade is arranged on a rod body of a driving rotating rod and located in a discharge barrel, so that materials entering the discharge barrel can be discharged upwards in sequence through the discharge threaded blade, falling of the materials is achieved, the time of the materials in a receiving barrel can be controlled while it can be guaranteed that the materials can fall through the structure, and the discharging efficiency of the materials is improved. And foaming and discharging of the materials can be achieved in time according to the proportion requirement, so that the efficiency in the foaming process is improved.

The invention discloses a coal bunker lower-locking-opening multi-coal-discharging-opening device, and belongs to the technical field of coal bunker coal discharging. The coal bunker lower-locking-opening multi-coal-discharging-opening device comprises a lower-locking-opening coal leakage platform assembly, the lower-locking-opening coal leakage platform assembly comprises a coal leakage platform, and a plurality of coal leakage openings are formed in the coal leakage platform; a coal leakage nozzle coal falling assembly is mounted at each coal leakage port, each coal leakage nozzle coal falling assembly comprises a coal leakage nozzle, and a plurality of spaced spokes are fixedly mounted at an opening of each coal leakage nozzle; the intervals of all the spaced spokes are sequentially increased or decreased by taking the coal leakage platform as the center; a rotary coal sweeping assembly is installed in the center of the coal leakage platform and comprises a main coal sweeping rotary rod, the main coal sweeping rotary rod is driven by a motor fixedly installed at the bottom of the coal leakage platform to rotate, and a plurality of auxiliary coal sweeping straight rods are vertically fixed to the lower portion of the main coal sweeping rotary rod. By means of the rotary coal sweeping assembly, coal briquettes clamped and blocked on the coal leakage nozzles with the small intervals of the spokes can be swept, a series of problems caused by coal briquette accumulation and the like are effectively avoided, and therefore it is guaranteed that the coal briquettes normally fall to the bottom of a coal bunker.

A piston installation tool, relating to the field of engine technology, is used to install a piston assembly into a cylinder liner. It includes an upper guide sleeve and a lower guide sleeve coaxially disposed below it. The upper guide sleeve has an upper through hole extending through both ends along its axial direction, the upper through hole comprising at least two axially connected guide hole segments, each guide hole segment being tapered. The lower guide sleeve has a lower through hole extending through both ends along its axial direction, the lower through hole being cylindrical, with the lower guide hole segment connected to the lower through hole. An operating window is provided on the upper guide sleeve, communicating with the upper through hole, the lower end of the operating window not exceeding the connection point between the guide hole segment and the lower through hole. This application can reduce tool height and production costs; simultaneously, it can adjust and reset piston rings, preventing piston rings from dislodging from the ring groove and improving yield.
