[0002] The gas blower oil station heat exchanger is a plate heat exchanger. The cooling water contains small particles of sand and other debris, which causes the oil station heat exchanger to be frequently blocked, causing the gas blower oil temperature to overheat. If the oil station heat exchanger is to be cleaned, the gas blower needs to be switched and the oil station heat exchanger is not easy to clean.

[0003] The prior art has the following technical defects:

[0004] The above technical solution can filter the cooling water of the plate heat exchanger, but the filter device needs to be cleaned after long-term use, and the machine needs to be shut down for cleaning, and it cannot be cleaned without shutting down the machine. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cooling water filtering system for a heat exchanger of a gas blower oil station.

[0006] The utility model discloses a gas blower oil station heat exchanger cooling water filtration system, comprising a plate filter, the plate filter is connected to a water inlet pipe, the water inlet pipe is connected to a filtering device, the water inlet pipes on both sides of the filtering device are connected to water inlet branches, and valves are provided on the water inlet branches and the water inlet pipes on both sides of the filtering device.

[0007] Working process or working principle:

[0008] During operation, cooling water enters the filter device through the water inlet pipe for filtration and then returns to the plate filter. When the filter device needs to be cleaned, the passage can be cut off by a valve to allow the cooling water to enter the plate filter through the water inlet branch pipe, thereby achieving the goal of not stopping operation during cleaning.

[0009] The filtering device comprises a shell, which is provided with a water inlet and outlet connected to a water inlet pipe, a plurality of filter plates are arranged inside the shell, and a cleaning box is slidably connected to the lower part of the shell, and impurities blocked by the filter plates are precipitated and fall into the cleaning box, through which the accumulated impurities can be removed.

[0010] The bottom of the shell is provided with a drain port, and a drain valve is provided in the drain port. When cleaning, the cooling water in the shell can be discharged through the drain valve first, and then the impurities can be cleaned.

[0011] The filter plate is slidably connected in the shell, and three filter plates are arranged in parallel. The filter holes on the three filter plates shrink from right to left, and the filter holes shrink from right to left. Large impurities can be blocked by the first filter plate, thereby avoiding clogging of the small-pore filter plate and prolonging the cleaning time.

[0012] A handle is provided on the top of the filter plate, which facilitates loading and unloading. During assembly, a shift rod can be passed through the handles of the three filter plates to fix them.

[0013] The water inlet branch pipe is connected with a Y-type filter, which plays a temporary filtering role when the filter device is cleaned, thereby preventing impurities in the cooling water from flowing into the plate heat exchanger.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model can clean the filter device without stopping the machine, has a simple structure, high cleaning efficiency, and can be reassembled and used in a short time. BRIEF DESCRIPTION OF THE DRAWINGS
