Description

Technical Field

[0001] The utility model belongs to the technical field of elongated horizontal shafted screw conveyors, and relates to an electric lubrication device for a screw hanging shaft mechanism of an elongated four-shaft screw conveyor. Background Art

[0002] A screw conveyor is a mechanical device that uses a motor to drive a screw to rotate, and materials are conveyed at fixed points under the thrust of screw blades relying on their own gravity and friction with the groove wall; an elongated horizontal screw conveyor refers to a screw conveyor whose conveying direction is parallel to the ground and has a long conveying stroke; an elongated horizontal screw conveyor refers to a horizontal screw conveyor with multi-section screws exceeding 30 meters; an elongated four-shaft horizontal screw conveyor is a screw conveyor with four sets of screws, which is mainly composed of a reduction motor, screw rotating shafts, screw blades, a U-shaped long trough, a long trough cover plate, a head bearing, a tail bearing, a screw hanging shaft mechanism, a motor coupling, a feeding hopper and a discharge port, and is a filter cake conveying equipment matched with a filter press.

[0003] The screw hanging shaft mechanism is mainly composed of seven parts: a hanger crossbeam, a square tube hanging rib, an oil injection assembly, an assembled outer shaft sleeve, a nylon inner shaft sleeve, an anti-drop chuck and a coupling rotating body. It is used to connect the screw rotating shafts on both sides thereof, and balances the screw rotating shafts on both sides by connecting them, so as to prevent the screw rotating shafts from deforming under the action of gravity due to overlong length; the oil injection assembly is composed of an oil injection hopper and an oil injection conduit, an oil outlet of the oil injection hopper is welded to one end of the oil injection conduit, and the other end of the oil injection conduit leads into the assembled outer shaft sleeve, so that lubricating oil can be input into the nylon shaft sleeve inside the assembled outer shaft sleeve.

[0004] Existing refueling and lubrication methods for the screw hanging shaft mechanism of an elongated four-shaft screw conveyor all have the following defects: due to the relatively large "size" of the elongated four-shaft screw conveyor, it is inconvenient to inject oil into the oil injection assembly in the middle part. When necessary, personnel need to stand into the screw conveyor to add lubricating oil into the oil injection assembly, which not only requires stopping the operation of the screw conveyor and delaying production, but also has certain potential safety hazards. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the defects of inconvenient oil injection lubrication and potential safety hazards in the existing screw hanging shaft mechanism of an elongated four-shaft screw conveyor, solve the corresponding technical problems, and provide an electric lubrication device for a screw hanging shaft mechanism of an elongated four-shaft screw conveyor.

[0006] The technical solution adopted by this utility model to solve the existing technical problems is: an electric lubrication device (hereinafter referred to as: electric lubrication device) for the screw shaft mechanism of an extended four-axis screw conveyor, mainly composed of five parts: an electric oil pump, an oil distribution assembly, a main oil pipe, branch oil pipes, and end connectors. The main oil pipe is characterized in that: one end is installed at the oil outlet of the electric oil pump, and the other end is installed on the main connector of the oil distribution assembly; one end of each of the four branch oil pipes is installed on one of the four branch connectors of the oil distribution assembly, and the other end is installed on one of the four end connectors; the four end connectors are respectively installed on the extended four-axis screw conveyor... The oil inlets are located on the four spiral shaft mechanisms of the machine. The electric oil pump can be started by buttons on the control panel. The electric oil pump provides power to deliver lubricating oil to each spiral shaft mechanism. Additionally, the oil distribution assembly is equipped with four branch ball valves. By opening or closing a specific branch ball valve, lubrication can be selectively applied to a particular spiral shaft mechanism. This electric lubrication device is installed entirely on the outer wall of the extended four-axis spiral conveyor casing. It allows for one-button operation to lubricate the spiral shaft mechanisms without shutting down the equipment, improving production efficiency. Furthermore, workers do not need to step into the extended four-axis spiral conveyor, eliminating safety hazards.

[0007] Furthermore, the electric oil pump is a 20171-2 type single-line damping throttling electric lubrication oil pump, which is equipped with an oil reservoir for storing lubricating oil; the electric oil pump is equipped with an oil outlet, one end of the main oil pipe is installed at the oil outlet of the electric oil pump, and the other end is installed on the oil distribution assembly, so that the electric oil pump is connected to the oil distribution assembly; the electric oil pump is also equipped with an operation panel, which can be used to control the start and stop of the electric oil pump by pressing the start button and the stop button. When the electric oil pump is started, it can output the lubricating oil in the oil reservoir.

[0008] Furthermore, the oil distribution assembly comprises four parts: a distribution block, branch ball valves, a main connector, and branch connectors. The distribution block is made of 100mm×50mm×50mm rectangular carbon steel through drilling. The distribution block has an internal elongated hole with an inner diameter of 16mm and a length of 90mm. An internal thread is provided at the hole opening, where a plug is installed. The distribution block also has a main oil inlet hole with an inner diameter of 16mm, which extends from the outside of the distribution block into the internal elongated hole, perpendicular to the direction of the hole. An internal thread is provided at the hole opening for installing the main connector. The distribution block also has four branch oil outlet holes with an inner diameter of 9mm. The external outlet of the self-distribution block leads to the elongated hole inside the block, perpendicular to the direction of the elongated hole. An internal thread is provided at the opening for installing branch ball valves. The branch ball valves are DN6 manual ball valves, with an internal thread at one end and an external thread at the other. The internal thread ends of the four branch ball valves are installed on the four branch oil outlet holes of the oil distribution assembly, and the external thread ends are installed with the branch connectors. The main connector is a PC12-03 quick connector, installed on the main oil inlet hole. The branch connectors are PC8-01 quick connectors, installed on the internal thread ends of the four branch ball valves. The function of the oil distribution assembly is to divide the lubricating oil input by the electric oil pump into four output paths.

[0009] Furthermore, the main oil pipe is a plastic hose with an outer diameter of 12mm. The two ends of the main oil pipe are respectively connected to the oil outlet of the electric oil pump and the main connector of the oil distribution assembly, for connecting the electric oil pump and the oil distribution assembly.

[0011] Furthermore, the end connector adopts a quick connector of model PC8-01. The electric lubrication device is equipped with four end connectors, which are respectively installed at the oil inlet of the screw shaft mechanism. The end connectors are also connected to branch oil pipes, which serve to direct the lubricating oil flowing out of the oil distribution assembly into the screw shaft mechanism along the branch oil pipes.

[0012] The electric lubrication device for the extended four-axis screw conveyor screw shaft mechanism provided by this utility model has the advantages of electric oil injection, convenient operation, and selectable branch oil injection. It is installed on the outer wall of the screw conveyor casing. The oil injection and lubrication can be performed at any time by operating the start button on the electric oil pump. The operation is convenient and does not require stopping the machine, which improves production efficiency. At the same time, it eliminates the need for workers to step into the screw conveyor, thus eliminating safety hazards. Moreover, the oil injection and lubrication of a specific screw shaft mechanism can be controlled by opening or closing the four branch ball valves, which improves convenience.
