Description

Technical Field

[0001] This utility model relates to the field of oil cooler technology, and in particular to an air-cooled oil cooler with the effect of preventing oil sludge blockage. Background Technology

[0002] An oil cooler is a device used to lower the oil temperature in a hydraulic system, maintaining the oil temperature at a suitable level to ensure the normal operation of the equipment. Air-cooled oil coolers are widely used in hydraulic systems due to their high efficiency, environmental friendliness, and energy saving.

[0003] However, during long-term use, existing oil coolers will produce a lot of grease in the high-temperature oil. This grease can easily block the oil flow channels, thus affecting the cooling efficiency of the cooler. Utility Model Content

[0004] This invention proposes an air-cooled oil cooler with anti-oil sludge clogging effect, aiming to solve the problem in traditional technology where high-temperature oil produces a lot of oil sludge that blocks the oil flow channels, thus affecting the cooling efficiency of the cooler.

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

[0006] An air-cooled oil cooler with anti-oil sludge clogging effect, comprising:

[0007] A housing, the top of which is connected to an oil inlet pipe;

[0008] A filter is installed inside a housing. The filter's inlet is connected to the inside of the housing, and its outlet is connected to an oil delivery pipe, which is installed at the bottom of the housing.

[0009] An anti-clogging component includes a filter cylinder, a rotating shaft, and spiral blades. The filter cylinder is connected to the oil pipeline. The rotating shaft is coaxially rotatably connected inside the filter cylinder. Spiral blades are coaxially fixedly connected to the rotating shaft. The edges of the spiral blades abut against the inner circumference of the filter cylinder.

[0010] The cooler body contains a cooler core, and the oil supply pipe is connected to the cooler body at the end away from the housing. The anti-clogging component is located inside the cooler body.

[0011] Preferably, a pressure relief pipe is connected to the housing, and a pressure relief valve is installed on the pressure relief pipe.

[0012] Preferably, the filter screen is coaxially and slidably connected to the outer periphery of the oil pipeline, and a buffer spring is fixedly connected between the filter screen and the outer periphery of the oil pipeline.

[0013] Preferably, a connecting frame is fixedly connected to the bottom of the housing, and the end of the connecting frame away from the housing is fixedly connected to the outside of the cooler body.

[0014] Preferably, a collecting blade is coaxially fixedly connected to the spiral blade near the cooler body. The collecting blade is arc-shaped, and the center of the arc is located on the side facing the direction of rotation.

[0015] Preferably, an elastic strip is fixedly connected to the outer periphery of the collecting blade, and the side of the elastic strip away from the collecting blade abuts against the inner periphery of the filter cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, the spiral blades on the filter screen cylinder rotate under the action of oil flow, and their outer circumference continuously sweeps across the inner surface of the filter screen cylinder, thereby preventing the filter screen cylinder from being blocked by oil stains in the high-temperature oil; at the same time, the collecting blades rotate accordingly to collect the oil stains in the high-temperature oil on the inner surface of the filter screen cylinder into the arc-shaped inner side of the collecting blades, further preventing the oil stains in the high-temperature oil from adhering to the filter screen cylinder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 An air-cooled oil cooler with anti-oil sludge clogging effect, comprising:

[0024] The housing 1 has an oil inlet pipe 2 connected to its top; the filter 5 is installed inside the housing 1, with its input end connected to the inside of the housing 1 and its output end connected to an oil delivery pipe 3, which is installed at the bottom of the housing 1; the oil enters the housing 1 through the oil inlet pipe 2, and then passes through the filter 5 before entering the oil delivery pipe 3.

[0025] The housing 1 is connected to a pressure relief pipe 4, and a pressure relief valve 41 is installed on the pressure relief pipe 4. When the oil pressure inside the housing 1 is too high, the pressure relief valve 41 in the pressure relief pipe 4 will automatically open to relieve the pressure inside the housing 1.

[0026] The anti-clogging component includes a filter cylinder 6, a rotating shaft 7, and spiral blades 8. The filter cylinder 6 is connected to the oil supply pipe 3. The rotating shaft 7 is coaxially rotatably connected inside the filter cylinder 6. The spiral blades 8 are coaxially fixedly connected to the rotating shaft 7, and the edges of the spiral blades 8 abut against the inner circumference of the filter cylinder 6. The cooler body 12 has a cooler core 13 installed inside it. The end of the oil supply pipe 3 away from the housing 1 is connected to the cooler body 12. The anti-clogging component is located inside the cooler body 12. The spiral blades 8 rotate under the action of oil flow. The outer circumference of the spiral blades 8 continuously sweeps across the inner surface of the filter cylinder 6, thereby effectively preventing the filter cylinder 6 from being clogged by oil sludge in the high-temperature oil.

[0027] A connecting frame 11 is fixedly connected to the bottom of the housing 1. The end of the connecting frame 11 away from the housing 1 is fixedly connected to the outside of the cooler body 12. The connecting frame 11 is used to improve the connection stability between the housing 1 and the cooler body 12.

[0028] The filter cylinder 6 is coaxially and slidably connected to the outer periphery of the oil pipeline 3. A buffer spring is fixedly connected between the filter cylinder 6 and the outer periphery of the oil pipeline 3. When the buffer spring is stretched, the filter cylinder 6 slides to expose more filtration area to maintain the filtration effect.

[0029] A collecting blade 9 is coaxially fixedly connected to the spiral blade 8 near the cooler body 12. The collecting blade 9 is arc-shaped, and the center of the arc is located on the side facing the direction of rotation. An elastic strip 10 is fixedly connected to the outer periphery of the collecting blade 9. The side of the elastic strip 10 away from the collecting blade 9 abuts against the inner periphery of the filter screen cylinder 6. The collecting blade 9 rotates with the spiral blade 8, thereby collecting the oil stains in the high-temperature oil on the inner surface of the filter screen cylinder 6 into the arc-shaped inner side of the collecting blade 9, further preventing the oil stains in the high-temperature oil from adhering to the filter screen cylinder 6.

[0030] The operating principle of this utility model is described as follows:

[0031] Oil enters the housing 1 through the oil inlet pipe 2. When the oil pressure in the housing 1 is too high, the pressure relief valve 41 in the pressure relief pipe 4 will open automatically to relieve the pressure in the housing 1 and discharge the oil, thus preventing the oil cooler from bursting.

[0032] After passing through the filter 5, the oil in the housing 1 is introduced into the oil supply pipe 3. Under the action of the oil flow, the spiral blades 8 on the filter screen cylinder 6 in the oil supply pipe 3 rotate. The outer periphery of the spiral blades 8 continuously sweeps across the inner surface of the filter screen cylinder 6, thereby effectively preventing the filter screen cylinder 6 from being blocked by oil stains in the high-temperature oil.

[0033] At the same time, the collecting blade 9 rotates to collect the oil stains in the high-temperature oil on the inner surface of the filter cylinder 6 into the arc-shaped inner side of the collecting blade 9, further preventing the oil stains in the high-temperature oil from adhering to the filter cylinder 6.

[0034] Driven by the oil, the filter cylinder 6 can slide to expose more of the filtration area, thus maintaining the filtration effect.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
