Description

Technical Field

[0001] This utility model relates to the field of blowers, and in particular to a device for reducing the oil temperature of blower oil stations. Background Technology

[0002] A blower mainly consists of the following six parts: motor, air filter, blower body, air chamber, base (also serving as oil tank), and oil drip nozzle. The blower operates by the eccentric rotation of an offset rotor within the cylinder, causing volume changes between the blades in the rotor slots to draw in, compress, and expel air. During operation, the pressure difference of the blower automatically delivers lubricant to the oil drip nozzle, dripping it into the cylinder to reduce friction and noise, while also preventing backflow of gas within the cylinder. This type of blower is also known as a vane blower.

[0003] In existing technologies, the lubricating oil in blowers absorbs a significant amount of heat during lubrication, especially during high-load operation, where its temperature rises considerably. Excessive lubricating oil temperature can lead to reduced lubrication effectiveness and even oil deterioration, affecting the normal operation of the equipment. Therefore, devices are needed to cool the lubricating oil in the blower oil station. Currently, most blower oil stations use plate heat exchangers to cool the lubricating oil. High-temperature lubricating oil is passed into the plate heat exchanger, followed by cooling water. The heat is removed from the lubricating oil through heat exchange, achieving cooling. However, during prolonged use, impurities in the lubricating oil and scale formed by the cooling water can enter the plate heat exchanger, causing blockages. This leads to poor backflow of cooling water and lubricating oil, reducing the heat exchange and cooling efficiency. Furthermore, direct recirculation of cooling water into the plate heat exchanger can cause pressure buildup, further affecting the smoothness of water circulation. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the filtration mechanism, in conjunction with the plate heat exchanger, allows lubricating oil and cooling water to pre-enter the plate heat exchanger via the oil inlet pipe and water inlet pipe, respectively, through the first and second connecting pipes. This pre-filters allow the lubricating oil and cooling water to enter the filter box separately. The coarse and fine filter screens installed in the filter box provide dual filtration of impurities in the lubricating oil and scale in the cooling water, preventing clogging of the plate heat exchanger due to impurities and scale. Once the lubricating oil and cooling water enter the plate heat exchanger through the hot and cold medium inlets, respectively, the plate heat exchanger cools the lubricating oil in the blower oil station through heat exchange. This is further enhanced by the circulation mechanism. The use of this system allows the cooling water in the plate heat exchanger to be discharged into the storage tank through the return water pipe for collection, temporary storage, and natural cooling, avoiding direct circulation of the cooling water. This reduces the internal pressure of the plate heat exchanger. After closing the second valve and opening the first valve, the cooling water in the storage tank is pumped out through the pump body and then pumped back into the plate heat exchanger through the delivery pipe for reuse, thus achieving the purpose of circulating the cooling water and avoiding waste of water resources. After cooling, the lubricating oil will flow back to the blower oil station through the return oil pipe for reuse, thereby improving the heat exchange and cooling effect of the lubricating oil and ensuring the smooth circulation of lubricating oil and cooling water when cooling through the plate heat exchanger.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 - Figure 5 As shown, the device for reducing the oil temperature of the blower oil station includes a water tank 1. A plate heat exchanger 2 is fixedly connected to the top surface of the water tank 1, and a return water pipe 3 connects the cold medium outlet of the plate heat exchanger 2 and the water tank 1. A first connecting pipe 5 and a second connecting pipe 7 are fixedly connected to the hot medium inlet and cold medium inlet of the plate heat exchanger 2, respectively. A filter mechanism 9 is provided at one end of the first connecting pipe 5 and the second connecting pipe 7, respectively. The filter mechanism 9 includes a filter box 18, a concave plate 21, a sealing box cover 24, a bottom plate 25, a screw 29, a coarse filter screen 32, and a fine filter screen 33. The concave plate 21 is fixedly connected to the top surface of the filter box 18, and the screw 29 is movably connected to the concave plate. On the top surface of 21, the screw 29 is also movably connected to the sealing box cover 24 through the rotating block 30 at the bottom end, and the bottom plate 25 is fixedly connected to the bottom surface of the sealing box cover 24. The coarse filter screen 32 and the fine filter screen 33 are respectively fixedly connected to the bottom surface of the bottom plate 25 through the insert strip 34 on the top surface. The right side wall of the water storage tank 1 is also provided with a circulation mechanism 10, and the circulation mechanism 10 includes a pump body 13, a delivery pipe 14, a T-shaped pipe 15 and a second valve 17. The input end of the pump body 13 is fixedly connected to the outlet 12 on the right side of the water storage tank 1, and the delivery pipe 14 is fixedly connected to the output end of the pump body 13. The bottom end of the T-shaped pipe 15 and the delivery pipe 14 are fixedly connected to the second valve 17.

[0022] like Figure 1 and Figure 3 - Figure 5As shown, the plate heat exchanger 2 is fixedly connected to the top surface of the water storage tank 1. The heat medium inlet of the plate heat exchanger 2 is fixedly installed with a first connecting pipe 5, the heat medium outlet of the plate heat exchanger 2 is fixedly installed with a return oil pipe 4, and the cold medium inlet of the plate heat exchanger 2 is fixedly installed with a second connecting pipe 7. This ensures that high-temperature lubricating oil and low-temperature cooling circulating water can enter the plate heat exchanger 2 from the corresponding heat medium inlet and cold medium inlet on the plate heat exchanger 2 through the first connecting pipe 5 and the second connecting pipe 7, respectively, to achieve heat exchange and cooling treatment. The return oil pipe 4 allows the lubricating oil that has been cooled to be discharged from the heat medium outlet on the plate heat exchanger 2 and then returned to the blower oil station for use.

[0023] like Figure 1 and Figure 3 - Figure 5 As shown, there are two filter boxes 18, one upper and one lower. A discharge pipe 20 and an inlet pipe 19 are fixedly installed on the left and right side walls of the filter box 18, respectively. The first connecting pipe 5 is fixedly installed together with the discharge pipe 20 on the left side of the upper filter box 18. An oil inlet pipe 6 is also fixedly installed on the inlet pipe 19 on the right side of the upper filter box 18. The second connecting pipe 7 is fixedly installed together with the discharge pipe 20 on the left side of the lower filter box 18. Lubricating oil and cooling water can be pre-entered into the filter box 18 for filtration through the inlet pipe 19. The discharge pipe 20 can pass the filtered lubricating oil and cooling water into the plate heat exchanger 2 through the first connecting pipe 5 and the second connecting pipe 7, respectively.

[0024] like Figure 1 and Figure 3 - Figure 5 As shown, an inverted concave plate 21 is fixedly installed on the top surface of the filter box 18, and sliding openings 22 are respectively opened on the left and right side walls of the concave plate 21. The sliding openings 22 are used to cooperate with the slider 28 to achieve sliding operation. A screw hole 23 is opened on the top surface of the concave plate 21. The screw hole 23 is used to cooperate with the screw 29 to achieve threaded rotation operation.

[0025] like Figure 1 and Figure 3 - Figure 5As shown, screw 29 is threadedly connected to screw hole 23, and a rotating block 30 is fixedly installed at the bottom end of screw 29. A handwheel 31 is fixedly installed at the top end of screw 29. A groove 27 is opened on the top surface of the sealing box cover 24, and the rotating block 30 is movably installed in the groove 27. Slider blocks 28 are fixedly installed on the left and right side walls of the sealing box cover 24, and the sliders 28 are movably installed in the sliding opening 22. A base plate 25 is also fixedly installed on the bottom surface of the sealing box cover 24, and a set of symmetrical T-shaped slots 26 are opened on the bottom surface of the base plate 25. T-shaped inserts 34 are fixedly installed on the top surfaces of coarse filter screen 32 and fine filter screen 33, and are inserted into the slots 26 from right to left. After the lubricating oil and cooling water enter the filter box 18, they flow from right to left through the filter box 18. The coarse filter 32 and fine filter 33 installed on the left can perform dual filtration of impurities in lubricating oil and scale in cooling water, ensuring that impurities and scale do not enter the plate heat exchanger 2 and cause blockage, thereby improving the heat exchange and cooling effect of the plate heat exchanger 2 on lubricating oil. Rotating the handwheel 31 drives the screw 29 to rotate, so that the screw 29 drives the sealing box cover 24 upward through the rotating block 30 at the bottom end in the groove 27, and drives the coarse filter 32 and fine filter 33 to move out of the filter box 18 through the bottom plate 25. After the coarse filter 32 and fine filter 33 are pulled out from the bottom plate 25, the impurities and scale filtered out by the coarse filter 32 and fine filter 33 and the filter box 18 can be cleaned to avoid impurities affecting the filtration effect of the filtration mechanism 9 on lubricating oil and cooling water.

[0026] like Figure 2 As shown, an inlet 11 is fixedly installed on the top surface of the water storage tank 1, and a return water pipe 3 is fixedly installed between the inlet 11 and the cold medium outlet of the plate heat exchanger 2. An outlet 12 is fixedly installed on the right side wall of the water storage tank 1, and the outlet 12 is fixedly installed together with the output end of the pump body 13. A delivery pipe 14 is fixedly installed on the output end of the pump body 13, and a second valve 17 is fixedly installed at the top of the delivery pipe 14. A T-shaped pipe 15 is fixedly installed at the top of the second valve 17, and the left end of the T-shaped pipe 15 is fixedly installed together with the inlet pipe 19 on the right side of the filter box 18 below. A first valve 16 is fixedly installed at the right end of the T-shaped pipe 15, and the second valve 17 is fixedly installed at the top of the second valve 17. A water inlet pipe 8 is fixedly installed on the right end of valve 16. After the cooling water in the plate heat exchanger 2 is discharged, it will be discharged into the water storage tank 1 through the return water pipe 3 from the water inlet 11 for temporary storage and natural cooling. This avoids the cooling water from directly circulating into the plate heat exchanger 2 and causing pressure buildup. When using the cooling water in the water storage tank 1, the first valve 16 can be closed and the second valve 17 and pump body 13 can be opened. The pump body 13 will draw the cooling water in the water storage tank 1 through the water outlet 12 and deliver it to the T-shaped pipe 15 through the delivery pipe 14. Then, it will be filtered by the filter mechanism 9 and the second connecting pipe 7 and recirculated back into the plate heat exchanger 2 to cool the lubricating oil.

[0027] It should be noted that this utility model is a device for reducing the oil temperature of a blower oil station. When cooling the lubricating oil in the blower oil station, the second valve 17 is closed and the first valve 16 is opened. After high-temperature lubricating oil and cooling water are supplied to the plate heat exchanger 2 through the oil inlet pipe 6 and the water inlet pipe 8, the high-temperature lubricating oil and cooling water will enter the filter box 18 through the inlet pipe 19 on the right side of the upper and lower filter boxes 18 respectively. The cooling water in the water inlet pipe 8 will first enter through the T-shaped pipe 15 and then enter the filter box 18. After the lubricating oil and cooling water have entered the filter box 18 respectively, the coarse filter screen 32 and the fine filter screen 33 installed in the filter box 18 will... The system filters out large and small impurities in the lubricating oil and large and small scale in the cooling water. The filtered lubricating oil and cooling water are discharged through the discharge pipe 20 installed on the left side of the filter box 18. High-temperature lubricating oil enters the plate heat exchanger 2 through the first connecting pipe 5 from the hot medium inlet, while cooling water enters the plate heat exchanger 2 through the second connecting pipe 7 from the cold medium inlet. When the high-temperature lubricating oil and low-temperature cooling water enter the plate heat exchanger 2 together, according to the principle of heat exchange, the low-temperature cooling water absorbs heat from the high-temperature lubricating oil. After the heat is absorbed, the high-temperature lubricating oil... The temperature of the heat exchanger itself will decrease to cool the lubricating oil in the blower oil station. After cooling, the lubricating oil will flow back to the blower oil station through the return oil pipe 4 installed at the hot medium outlet of the plate heat exchanger 2 for use. The cooling water discharged through the cold medium outlet of the plate heat exchanger 2 will be discharged into the water storage tank 1 through the water inlet 11 installed on the top surface of the water storage tank 1 via the return water pipe 3, avoiding direct circulation of cooling water into the plate heat exchanger 2. This reduces the pressure inside the plate heat exchanger 2 and allows the cooling water with a certain temperature to be temporarily stored and recycled in the water storage tank 1 for natural cooling. When not in use, the cooling water can be cooled by external inlet... When the cooling water is transported by the water pipe 8, the first valve 16 can be closed and the second valve 17 and pump body 13 can be opened. The pump body 13 will draw the cooling water in the water storage tank 1 through the outlet 12 and transport it to the T-shaped pipe 15 through the delivery pipe 14 installed on the output end. Then, it will enter the plate heat exchanger 2 through the filter mechanism 9 and the second connecting pipe 7 to cool the lubricating oil. This can prevent the plate heat exchanger 2 from being blocked by impurities and scale, thereby improving the heat exchange and cooling effect of the lubricating oil and ensuring the smooth circulation of lubricating oil and cooling water when cooling through the plate heat exchanger 2.

[0028] To prevent the filter box 18, coarse filter screen 32, and fine filter screen 33 from becoming clogged with impurities, thus affecting the filtration effect on lubricating oil and cooling water, the impurities filtered out of the filter box 18 can be cleaned periodically. This is done by rotating the handwheel 31 on the top surface of the inverted concave plate 21 of the upper and lower filter boxes 18. The handwheel 31 will drive the screw 29 to rotate within the screw hole 23 on the top surface of the concave plate 21 and move it upwards. The screw 29 will also drive the rotating block 30 installed at the bottom to rotate within the groove 27 on the top surface of the sealing cover 24, and through the rotating block 30, drive the sealing cover 24 to move upwards. During this movement, the sliders 28 installed on both sides of the sealing cover 24 will move within the concave plate 21. The filter slides through the sliding openings 22 on both sides until the base plate 25 installed on the bottom surface of the sealed cover 24 pulls the coarse filter 32 and fine filter 33 out of the filter box 18. Then, the coarse filter 32 and fine filter 33 are pulled out from the bottom surface of the base plate 25, so that the inserts 34 installed on the top surface of the coarse filter 32 and fine filter 33 can be removed from the slots 26 opened on the bottom surface of the base plate 25. This allows the coarse filter 32 and fine filter 33 to be disassembled, cleaned, or replaced, and the impurities in the filter box 18 to be cleaned. The cleaning operation is simple and convenient, ensuring the filtration effect of the filter mechanism 9 on the lubricating oil and cooling water during long-term use, preventing the plate heat exchanger 2 from becoming clogged, and ensuring the heat exchange efficiency of the plate heat exchanger 2.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
