Description

Technical Field

[0001] The utility model belongs to the field of industrial lubricating oil filtration and relates to a fire-resistant oil processing device, in particular to a fire-resistant oil filtering processing device. Technical Background

[0002] Phosphate ester fire-resistant oil is a hydraulic oil that must be used in the speed control system of power companies. Phosphate ester fire-resistant oil is expensive, polluting the environment and toxic. When the generator set is running, it must be ensured that the indicators of phosphate ester fire-resistant oil meet the operating oil standards. Therefore, it is essential to use a fire-resistant oil filter to maintain and treat it. However, after filtering, the residual oil in the filter of the oil filter on the market cannot be discharged into the oil system as much as possible, which not only causes waste to the power generation company, but also causes pollution and poisoning to the environment when replacing the large amount of residual oil in the filter element. Therefore, how to discharge the residual oil in the filter and the filter element into the oil system as much as possible when replacing the filter element is an urgent problem to be solved. Utility Model Content

[0003] In order to solve the above technical problems existing in the background technology, the utility model provides a fire-resistant oil filtering and processing device which has low working intensity, reduces leakage of residual oil in fire-resistant oil and effectively improves working efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A fire-resistant oil filtering and processing device, characterized in that: the fire-resistant oil filtering and processing device includes an oil filter circuit, a filter and an oil drain circuit; the filter is arranged on the oil filter circuit; the filter is connected to the oil drain circuit; the flow direction of the fire-resistant oil in the oil filter circuit is opposite to the flow direction of the fire-resistant oil in the oil drain circuit.

[0006] The fire-resistant oil filtering and processing device further comprises an oil inlet valve, a check valve and a first valve; the oil inlet valve, the first valve, the filter and the check valve are arranged in sequence from front to back on the oil filtering oil path.

[0007] The fire-resistant oil filtering and processing device also includes an oil pump; the oil inlet valve is connected to the first valve through the oil pump; the oil discharge circuit includes a first oil discharge pipe; the filter is connected to the oil pump through the first oil discharge pipe; and a second valve is provided on the first oil discharge pipe.

[0008] The oil drain circuit comprises a second oil drain pipe, the first oil drain pipe is connected with the second oil drain pipe through an oil pump; and a third valve is arranged on the second oil drain pipe.

[0009] The fire-resistant oil filtering and processing device further comprises an oil outlet valve; the filter and the oil outlet valve are sequentially arranged on the oil filter oil path from front to back; the filter is connected with the oil outlet valve through the oil discharge oil path.

[0010] The advantages of the utility model are:

[0011] The utility model provides a fire-resistant oil filtering and processing device, including an oil filter oil circuit, a filter and an oil discharge oil circuit; the filter is arranged on the oil filter oil circuit; the filter and the oil discharge oil circuit are connected; the flow direction of the fire-resistant oil in the oil filter oil circuit is opposite to the flow direction of the fire-resistant oil in the oil discharge oil circuit. During operation, the filter is turned on, and the fire-resistant oil passes through the oil filter oil circuit to filter the fire-resistant oil. After the oil filtering work is completed, the filter is ensured to be immobile (that is, the filter is not removed or the filter element is removed from the filter), so that the oil discharge oil circuit works. Since the flow direction of the fire-resistant oil in the oil discharge oil circuit is opposite to the flow direction of the fire-resistant oil in the oil filter oil circuit, the fire-resistant oil in the filter flows back until the fire-resistant oil in the filter is discharged as completely as possible. That is, the utility model combines the oil inlet and the oil discharge port of the filter into one, and by changing the flow direction of the fire-resistant oil, the fire-resistant oil can be filtered and discharged without removing the filter or the filter element, which greatly simplifies the operation, reduces the work intensity, reduces the leakage of residual oil in the fire-resistant oil, and also improves the work efficiency of fire-resistant oil treatment.

[0017] See also Figure 1The utility model provides a fire-resistant oil filtering and processing device, including an oil filter oil circuit, a filter 4 and an oil drain oil circuit; the filter 4 is arranged on the oil filter oil circuit; the filter 4 is connected with the oil drain oil circuit; the flow direction of the fire-resistant oil in the oil filter oil circuit is opposite to the flow direction of the fire-resistant oil in the oil drain oil circuit. During operation, the filter 4 is turned on, and the fire-resistant oil passes through the oil filter oil circuit to filter the fire-resistant oil. After the oil filtering work is completed; ensure that the filter 4 does not move (that is, the filter 4 is not removed or the filter element is removed from the filter 4), so as to promote the operation of the oil drain oil circuit. Since the flow direction of the fire-resistant oil in the oil drain oil circuit is opposite to the flow direction of the fire-resistant oil in the oil filter oil circuit, the fire-resistant oil in the filter 4 flows back until the fire-resistant oil in the filter 4 is discharged as completely as possible. That is, the utility model combines the oil inlet and the oil drain of the filter 4 into one, and by changing the flow direction of the fire-resistant oil, it is finally possible to filter and drain the fire-resistant oil without removing the filter 4 or the filter element, which greatly simplifies the operation and improves the work efficiency.

At this time, the fire-resistant oil to be filtered and processed enters the filter 4 after passing through the oil inlet valve 1 and the first valve 6 in sequence, and is filtered and processed by the filter 4 before being discharged through the check valve 5; when the fire-resistant oil in the filter 4 needs to be discharged, the valve of the oil filter oil circuit is closed, the oil discharge oil circuit is opened, and the fire-resistant oil in the filter 4 is extracted by an additional pump, so that the flow direction of the fire-resistant oil in the oil filter oil circuit is opposite to the flow direction of the fire-resistant oil in the oil discharge oil circuit, and the oil discharge is completed.

[0019] In order to further simplify the structure of the fire-resistant oil filtering and processing device provided by the utility model (i.e., to reduce the number of oil pumps), the fire-resistant oil filtering and processing device provided by the utility model also includes an oil pump 3; the oil inlet valve 1 is connected with the first valve 6 through the oil pump 3; the oil discharge circuit includes a first oil discharge pipe; the filter 4 is connected with the oil pump 3 through the first oil discharge pipe; and the first oil discharge pipe is provided with a second valve 7.

Exemplarily, the oil discharge circuit includes a second oil discharge pipe, the first oil discharge pipe is connected with the second oil discharge pipe through the oil pump 3; and the second oil discharge pipe is provided with a third valve 8.
