Description

Technical Field

[0001] This utility model belongs to the field of screw conveyor maintenance technology, and in particular relates to a lubrication and maintenance component for screw conveyor shafts. Background Technology

[0002] Screw conveyors, as core equipment for conveying bulk materials, are widely used in mining, chemical, and grain processing industries. The fitting accuracy between the shaft and bearing housing directly determines the operational stability of the equipment. In actual working conditions, the shaft is in a state of high-speed rotation for a long time, and the bearing housing needs to continuously maintain sufficient and highly fluid lubricating oil to reduce friction loss and prevent overheating and wear of components.

[0003] However, existing lubrication systems for screw conveyors generally suffer from poor low-temperature adaptability. When the equipment operates in cold regions or low-temperature workshops, the lubricating oil is prone to viscosity increase or even solidification during transport due to the low ambient temperature. Even if some systems have heating structures on the outside of the oil pipeline, this only ensures the fluidity of the lubricating oil within the pipeline. After entering the bearing housing, the lubricating oil comes into contact with the low-temperature bearing housing and shaft, causing rapid heat loss and a sudden drop in temperature. This leads to solidification or decreased fluidity, resulting in insufficient lubrication, causing bearing jamming, accelerated shaft wear, and other malfunctions. In severe cases, shutdown for maintenance is required, significantly reducing production efficiency and failing to meet the demands of efficient and stable operation in modern production. Therefore, there is an urgent need to improve existing systems and provide a lubrication and maintenance component for screw conveyor shafts. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a lubrication and maintenance component for the shaft of a screw conveyor that is reasonably designed, simple in structure, and has anti-solidification function, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lubrication and maintenance assembly for a screw conveyor shaft, comprising:

[0007] A frame, wherein a bearing seat is fixedly installed inside the right end of the frame, and an output shaft is installed on the bearing seat;

[0008] The insulated oil tank is fixedly installed on the upper right side of the frame and below the right end of the output shaft. A small oil pump is fixed on the front outer wall of the insulated oil tank. A first pipe is fixedly connected between the input end of the small oil pump and the oil outlet of the insulated oil tank. A second pipe is fixedly connected between the output end of the small oil pump and the oil inlet of the bearing seat.

[0009] A thermal insulation component is adhesively sleeved on the outer side of the middle part of the second connecting pipe, and a one-way valve is installed at the end of the second connecting pipe near the bearing seat;

[0010] The control components include a controller and an oil level sensor fixed to the top of the insulated oil tank.

[0011] In a preferred embodiment, an annular groove is provided on the outer wall of one end of the bearing housing, and a heating component is installed in the groove.

[0012] In a preferred embodiment, the heating assembly includes an annular heating element, positioning hoops, and a positioning mechanism. The annular heating element is composed of two semi-circular heating elements of the same size and is fixedly installed in the retention groove. Positioning hoops are symmetrically arranged on the upper and lower sides of the annular heating element. The two positioning hoops are connected by the positioning mechanism. The positioning hoops are made of heat-insulating material.

[0013] In a preferred embodiment, the positioning mechanism includes a bolt and a nut adapted to the bolt.

[0014] In a preferred embodiment, an oil injection pipe is embedded and fixed at the upper rear of the insulated oil tank, and a cap is threaded on the outer side of the top end of the oil injection pipe, and the top opening of the oil injection pipe is sealed by the cap.

[0015] In a preferred embodiment, the insulation component specifically includes an insulation surface layer and a heat insulation sleeve. The insulation surface layer is made of insulation cotton and is located between the second connecting pipe and the heat insulation sleeve.

[0016] In a preferred embodiment, both the heating component and the oil level sensor are electrically connected to the controller. The controller has a temperature control unit inside, which is electrically connected to the annular heating element. The outer wall of the controller has a temperature adjustment knob electrically connected to the temperature control unit, used to regulate the heating temperature of the annular heating element.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the solution of this utility model:

[0019] This screw conveyor shaft lubrication and maintenance component not only has a heat insulation component on the outside of the second connecting pipe, but also a heating component on the outside of the bearing housing end. Utilizing a wrap-around positioning clamp in conjunction with an annular heating plate, it can maintain the temperature of the bearing housing in a targeted manner, preventing the lubricating oil from solidifying due to sudden heat dissipation after entering the bearing housing. This ensures the fluidity of the lubricating oil after entering the bearing housing, significantly reducing shaft wear, bearing jamming, and other faults caused by lubrication failure, and extending the service life of the screw conveyor. It is especially suitable for long-term stable operation in cold regions or low-temperature workshops, effectively solving the industry pain point of lubricating oil easily solidifying in low-temperature environments.

[0020] The oil level sensor facilitates the monitoring of the reserve oil level inside the insulation oil tank, enabling timely replenishment. Furthermore, the small oil pump, first connecting pipe, and second connecting pipe facilitate the automatic addition of lubricating oil to the bearing housing. The one-way valve prevents lubricating oil backflow, ensuring stable and smooth filling. Attached Figure Description

[0033] The control components include a controller 18 and an oil level sensor 19 fixed to the top of the insulated oil tank 9.

[0034] Based on the above structure, an annular groove 4 is provided on the outer wall of one end of the bearing housing 3, and a heating component is installed in the groove 4.

[0035] In this embodiment, the opening of the retention slot 4 facilitates the installation of the heating component.

[0036] Based on the above structure, the heating assembly includes an annular heating element 5, a positioning hoop 6, and a positioning mechanism. The annular heating element 5 is composed of two semi-circular annular heating elements of the same model and size and is fixedly installed in the retention groove 4. The upper and lower sides of the annular heating element 5 are symmetrically provided with positioning hoops 6, and the two positioning hoops 6 are connected by the positioning mechanism. The positioning hoop 6 is made of heat insulation material.

[0037] In this embodiment, the use of a wrap-around positioning clamp 6 in conjunction with an annular heating element 5 can maintain the temperature of the bearing housing 3 in a targeted manner, preventing the lubricating oil from solidifying due to sudden heat dissipation after entering the bearing housing 3, ensuring the fluidity of the lubricating oil after entering the bearing housing 3, and significantly reducing failures such as shaft wear and bearing jamming caused by lubrication failure.

[0038] Based on the above structure, the positioning mechanism includes a bolt 7 and a nut 8 that is compatible with the bolt 7.

[0039] In this embodiment, the bolts 7 and nuts 8 are used to facilitate the installation of the positioning clamp 6. The positioning clamp 6 is made of thermal insulation material, which can reduce the heat dissipation of the annular heating element 5 to the outside.

[0040] Based on the above structure, an oil injection pipe 10 is embedded and fixed at the upper rear of the insulated oil tank 9. A cap 11 is threaded on the outer side of the top end of the oil injection pipe 10, and the top opening of the oil injection pipe 10 is sealed by the cap 11.

[0041] In this embodiment, the oil filling pipe 10 facilitates the filling of oil into the heat-insulating oil tank 9, and the cap 11 facilitates the sealing of the oil filling pipe 10.

[0042] Based on the above structure, the insulation component specifically includes an insulation surface layer 16 and a heat insulation sleeve 17. The insulation surface layer 16 is made of insulation cotton and is located between the second pipe 14 and the heat insulation sleeve 17.

[0043] In this embodiment, the use of the heat insulation component ensures the smooth flow of lubricating oil within the second pipe 14 and prevents it from solidifying at low temperatures.

[0044] Based on the above structure, the heating component and the oil level sensor 19 are both electrically connected to the controller 18. The controller 18 is equipped with a temperature control unit, which is electrically connected to the annular heating element 5. The outer wall of the controller 18 is equipped with a temperature adjustment knob 20, which is electrically connected to the temperature control unit, and is used to adjust the heating temperature of the annular heating element 5.

[0045] In this embodiment, the controller 18 and its internal temperature control unit and temperature adjustment knob 20 are used to facilitate reasonable control of the heating temperature of the annular heating element 5.

[0046] The working principle of this utility model is as follows:

[0047] In use, lubricating oil is first added to the heat-insulating oil tank 9 through the oil injection pipe 10, and the oil injection pipe 10 is sealed by tightening the cap 11. During the operation of the screw conveyor, the lubricating oil can be drawn out and transported to the internal oil cavity of the bearing seat 3 through the first pipe 13 and the second pipe 14 by opening the small oil pump 12 to achieve lubrication between the bearing seat 3 and the output shaft 2 of the equipment. The oil level sensor 19 is used to monitor the oil level in the heat-insulating oil tank 9 so as to add oil in time. Moreover, the one-way valve 15 can prevent the lubricating oil from flowing back and ensure the stability and smoothness of the filling.

[0048] This screw conveyor shaft lubrication and maintenance component not only features an insulation component on the outside of the second connecting pipe 14, using an insulation surface layer 16 and a heat insulation sleeve 17 to ensure smooth transmission of lubricating oil within the second connecting pipe 14, but also adds a heating component on the outside of the bearing housing 3 end. Utilizing a wrap-around positioning clamp 6 in conjunction with an annular heating element 5, it can maintain the temperature of the bearing housing 3 in a targeted manner, preventing the lubricating oil from solidifying due to sudden heat dissipation after entering the bearing housing 3. This ensures the fluidity of the lubricating oil after entering the bearing housing 3, significantly reducing shaft wear, bearing jamming, and other faults caused by lubrication failure, and extending the service life of the screw conveyor. It is especially suitable for long-term stable operation in cold regions or low-temperature workshops, effectively solving the industry pain point of lubricating oil easily solidifying in low-temperature environments. The controller 18 and its internal temperature control unit, along with the temperature adjustment knob 20, facilitate reasonable control of the heating temperature of the annular heating element 5.

[0049] It should be noted that this component is powered by an external power source.
