Description

Technical Field

[0001] This utility model relates to the field of oil filtration technology, and in particular to a multi-tank combination structure for oil filtration. Background Technology

[0002] Oil filtration is used to filter and reuse the coolant recovered from the processing equipment. The filter tank contains a filter element; considering the strength of the filter element and the overall size of the equipment, the filter tank cannot be too large. To increase the coolant throughput, the number of filter tanks must be increased, forming a multi-tank combination. The top of the filter tank has an oil outlet; all the clean oil discharged from these outlets must be collected and sent to a clean oil tank for later use. Existing multi-tank combinations often use a structure with the bottom of the tanks fixed and the top independent, which has poor stability. To address this drawback, a structure exists where the top is connected and sealed by a large cover plate. However, this structure requires lifting equipment to hoist the entire cover plate and open all the tanks at once for maintenance, which is very inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-tank combination structure for oil filtration that solves or partially solves the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multi-tank assembly structure for oil filtration includes a lower plate and an upper plate that are parallel to each other. A plurality of hollow tanks are arranged in an array between the lower and upper plates. The lower part of each tank is placed in an oil tank. A plurality of through openings are provided on the upper plate corresponding to the tanks, and the top of each tank is located within one of the openings. A plurality of oil collection pipes are provided below the upper plate, and a plurality of oil inlet holes are provided on each oil collection pipe corresponding to the tanks. The structure also includes a plurality of tank covers for sealing the tanks and a plurality of caps for sealing the oil inlet holes. Both the tank covers and the caps are connected to the upper plate by screws or bolts. Each tank cover is connected to a cap via a U-shaped pipe.

[0006] Preferably, the lower plate, upper plate, and tank body are welded into a single structure.

[0007] Preferably, a flange is welded to both the opening and the oil inlet, and the tank cover and cap are both connected to the flange by screws.

[0008] Preferably, each end face of the oil collection pipe is connected to an oil outlet pipe.

[0009] Preferably, the tank is arranged in two rows of six units each between the lower plate and the upper plate.

[0010] Preferably, a filter plate is provided on the top of each tank, and the filter plate is fixed to the tank by screws.

[0011] Preferably, one end of the oil collection pipe is provided with a gas pipe connecting to the oil collection pipe.

[0012] The beneficial effects of this invention are: the combination of upper and lower plates better fixes the tank body; the tank cover and cap are set separately, which can be opened independently without the aid of lifting equipment, simplifying the maintenance process; a flange is welded to both the opening and the oil inlet, which facilitates assembly and improves the overall and uniform performance of the structure, and the sealing performance is better.
