Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a speed reducer oil change device for a planetary mixing equipment. Background Technology

[0002] The existing planetary mixer's reducer oil change device uses the reducer's existing oil pump to construct a circulating oil circuit, and uses the opening and closing of valves on the pipeline to perform oil discharge and oil filling operations. When filling oil, the oil level is visually checked to see if it is in place.

[0003] The device has the following problems: limited location: the method uses the reducer's own oil pump, so it is inconvenient to operate when the reducer is in a high position; relatively low degree of automation: the entire oil change process requires manual intervention; oil filling and draining share a single pipeline: there is a problem of new oil being contaminated. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a speed reducer oil change device for planetary mixers, which can solve the problem of inconvenient oil change caused by the excessively high position of the speed reducer in large mixers. At the same time, the oil filling and draining are separated into two pipelines, which can avoid the contamination of new oil by waste oil. The oil is transported in the pipeline without contacting the outside world, so it will not cause pollution to the environment.

[0005] The technical solution adopted in this utility model is:

[0006] A speed reducer oil changing device for a planetary mixer is characterized by comprising two automatic valves, which are respectively located at the oil inlet and oil outlet of the speed reducer oil tank.

The two automatic valves are respectively connected to an oil pump and a waste oil collection device. The oil pump is connected to an oil storage device. The control unit is included in the overall control system of the planetary mixer and is connected to the two automatic valves, the level detector, and the oil pump. A controller is installed in the planetary mixer, and the controller is electrically connected to the two automatic valves, the oil pump, and the level detector.

[0007] Preferably, in the planetary mixer's reducer oil changing device, one end of the automatic valve at the oil inlet is connected to the oil pump via a first pipeline, and the other end of the automatic valve at the oil outlet is connected to the waste oil collection device via a second pipeline.

[0008] Preferably, in the planetary mixer's reducer oil change device, a first valve is installed at the end of the first pipeline furthest from the automatic valve.

[0009] Preferably, in the planetary mixer's reducer oil change device, a second valve is provided at the end of the second pipeline furthest from the automatic valve.

[0010] Preferably, the reducer oil changing device of the planetary mixer further includes a mobile trolley, on which the oil pump, waste oil collection device and oil storage device are all placed.

[0011] Preferably, in the planetary mixer's reducer oil change device, the oil inlet of the reducer oil tank is located at the top of the reducer oil tank, and the oil outlet of the reducer oil tank is located at the bottom of the reducer oil tank.

[0012] Preferably, in the planetary mixing equipment, the reducer oil changing device includes a high level detector and a low level detector, with one end of the low level detector extending into the reducer oil tank near the bottom.

[0013] Advantages of this utility model:

[0017] The present invention will be further described below with reference to the specific accompanying drawings and embodiments.

[0018] like Figure 1-2 A speed reducer oil changing device for a planetary mixer includes two automatic valves 1, which are respectively located at the oil inlet and oil outlet of a speed reducer oil tank 2. A level detector is installed on the top of the speed reducer oil tank 2, with one end of the level detector extending into the interior of the speed reducer oil tank 2. The two automatic valves 1 are respectively connected to an oil pump 3 and a waste oil collection device 4. The oil pump 3 is connected to an oil storage device 5. A controller is installed in the planetary mixer, and the controller is electrically connected to the two automatic valves 1, the oil pump 3, and the level detector. The controller can be a PLC controller.

[0019] One end of the automatic valve 1 installed at the oil inlet is connected to the oil pump 3 through the first pipeline 6, and the other end of the automatic valve 1 installed at the oil outlet is connected to the waste oil collection device 4 through the second pipeline 7.

[0020] A first valve 8 is installed at the end of the first pipeline 6 that is away from the automatic valve 1.

[0021] A second valve 9 is installed at the end of the second pipeline 7 that is away from the automatic valve 1.

[0022] The reducer oil changing device of the planetary mixer also includes a mobile trolley 10, on which the oil pump 3, waste oil collection device 4 and oil storage device 5 are all placed.

[0023] The oil inlet of the reducer oil tank 2 is located at the top of the reducer oil tank 2, and the oil outlet of the reducer oil tank 2 is located at the bottom of the reducer oil tank 2.

[0024] The liquid level detector includes a high liquid level detector 11 and a low liquid level detector 12, with one end of the low liquid level detector 12 extending into the inside of the reducer oil tank 2 near the bottom.

[0025] Both the high liquid level detector 11 and the low liquid level detector 12 are manufactured by Kunshan Danrui Sensor Measurement and Control Technology Co., Ltd. The model of the high liquid level detector 11 is TSR1001-80, and the model of the low liquid level detector 12 is TSR1001-450.

[0026] The first pipeline 6 and the second pipeline 7 are both connected to the automatic valve 1 and led to the vicinity of the ground. The oil pump 3 pumps new oil into the reducer oil tank 2. The oil storage device 5 stores the reducer lubricating oil, and the waste oil collection device 4 collects the waste oil discharged from the reducer oil tank.

[0027] The operation process of this utility model:

[0028] 1. When the reducer needs an oil change, the operator opens the two automatic valves 1 on the oil inlet and oil outlet through the controller to discharge the waste oil in the reducer oil tank 2 into the waste oil collection device 4;

[0029] 2. After the waste oil is drained, the low level detection device 12 is triggered. The low level signal is fed back to the controller. The controller sends a signal to close the automatic valve 1 of the drain port and start the oil pump 3 to add new oil to the reducer oil tank 2.

[0030] 3. Once the oil level is sufficient, the high-level detection device 11 is triggered, and the high-level signal is fed back to the controller. The controller then sends a signal to close the oil pump 3 and the automatic valve 1 at the oil inlet, thus completing the oil change.

[0031] This utility model relates to a speed reducer oil changing device for planetary mixing equipment, which solves the problem of inconvenient oil changing caused by the excessively high position of the speed reducer in large mixing equipment. It is not limited by the position of the speed reducer and can still be operated relatively easily when the speed reducer is in a high position. The operation is simple and quick, with a high degree of automation and minimal human intervention, except for the initial oil draining and oil pump connection. The oil filling and draining are separated into two pipelines, which can avoid the contamination of the new oil by waste oil. The oil is transported in the pipeline and does not come into contact with the outside environment, so it will not cause pollution to the environment.

Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
