Principle characteristics and maintenance of reciprocating feeder

2012-02-22 11:39:23 Reciprocating feeder principle characteristics and maintenance link address: http://www.hnshusongji.com/xwdt129.html Reciprocating feeder consists of frame, bottom plate, transmission platform, and hopper , Gate, roller, when the motor is activated, the inclined bottom plate is dragged by the elastic coupling, reducer, and crank connecting mechanism to make a linear reciprocating motion on the inserting roller, and the coal is uniformly discharged to the transportation machinery or other screening On the equipment, coal or other loose granular and powdery materials with small abrasiveness and low viscosity are uniformly discharged from the feeding equipment to the receiving equipment. The main features of the feeder: reliable work, long life, light weight, small size, convenient maintenance, simple structure, reliable operation, convenient adjustment and installation, closed frame structure, greatly improved the rigidity of the frame, and installed a limited moment The hydraulic coupling can be started at full load and has overload protection. It adopts the advanced design of plane secondary enveloping toroidal mule rod reducer. It has large load-bearing capacity and high transmission efficiency. There are seams between the side liner, the inclined liner and the bottom plate. Adjustable, can more accurately control the size of the remaining seam, greatly reduce the leakage, and use double push rods to balance the love of the whole machine, the transmission is stable, and the torsion phenomenon of the bottom plate is eliminated when the bottom plate is reciprocated. The bottom plate is used for vertical ribs. The three-way long idler support ensures the rigidity of the bottom plate and eliminates the defects of bending and deformation of the bottom plate of the existing reciprocating feeder. Working principle: When the motor is started, the inclined bottom plate is dragged by the elastic coupling, reducer, and crank connecting mechanism to make a linear reciprocating motion on the inserting roller, and the coal is uniformly discharged to the transportation machinery or other screening equipment. K-type reciprocating feeder has two types: with funnel, with regulating valve and without funnel, without regulating valve. This machine is suitable for mines and coal preparation plants. The coal is evenly loaded onto the loading conveyor or other screening and storage devices through the coal bunker. Routine maintenance: Before the feeder is operated, there should be enough raw coal in the coal bunker to avoid direct impact on the bottom plate when coal is loaded into the bunker. After continuous work every month, check whether the mechanical parts are loose and other abnormal phenomena. If the normal phenomenon occurs, it should be checked and repaired immediately. The thickness of the bottom liner directly in contact with coal must be repaired or replaced if its thickness is greater than one-half of the original thickness; the rotating parts need to be inspected after six months of continuous operation. The parts must maintain normal coordination. If there is any abnormality, repair or replace it immediately, check the reducer every six months, and clean the rolling bearing and the box or replace the lubricating oil.
