Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a hydraulic system cooling device. Background Technology

[0002] In the fields of industrial production and machinery operation, common hydraulic system cooling devices are key components to ensure the stable operation of equipment. Their working principle is based on a precise and orderly process, which aims to efficiently reduce the temperature of hydraulic oil and ensure that the hydraulic system is always in a suitable operating temperature range.

[0003] In existing technologies, common hydraulic system cooling devices filter air through a filter assembly before blowing it onto a heat exchanger to cool the circulating hydraulic oil. However, in actual use, when the filter plates accumulate a lot of dust, the airflow decreases, causing a sharp drop in heat exchange efficiency. Furthermore, if the replacement process is lengthy, the hydraulic system continues to operate and generate heat during this time, while the cooling device cannot function properly, leading to a continuous rise in hydraulic oil temperature. If this situation is not addressed promptly, excessively high oil temperatures can damage critical components such as seals and hydraulic pumps in the hydraulic system, affecting the normal operation and lifespan of the equipment. Therefore, an improved hydraulic system cooling device is needed to solve these problems. Utility Model Content

[0004] To overcome the problem that when the filter assembly is maintained or the filter plate is replaced, it will affect the cooling and heat dissipation of the hydraulic oil, causing the hydraulic oil temperature to accumulate and not be cooled down in time, thus affecting the normal operation of the equipment.

[0005] The technical solution of this utility model is as follows: a hydraulic system cooling device, including a mounting base plate, a first fixed box fixedly connected to the mounting base plate, a converter valve body disposed outside the first fixed box, a first connecting pipe fixedly connected between the first fixed box and the converter valve body, a sliding frame slidably connected to the first fixed box, a sealing assembly disposed on the first fixed box, a pre-filter plate disposed on the sliding frame, a dust filter plate disposed on the sliding frame, an activated carbon filter plate disposed on the sliding frame, a centrifugal fan fixedly connected to the mounting base plate, a second connecting pipe fixedly connected between the centrifugal fan and the first fixed box, a heat exchange assembly disposed on the mounting base plate, and a refrigeration box body disposed between the heat exchange assembly and the centrifugal fan.

[0006] Preferably, the first fixed box has a storage groove at the relative position of the sliding frame, and the sliding frame is slidably connected to the groove.

[0007] Preferably, the sealing assembly includes a first fixed seat fixedly connected to a first fixed box, a connecting bracket disposed on the first fixed seat, a first fixed rod fixedly connected to the connecting bracket and the first fixed seat, a rotating block slidably connected to the first fixed rod, a connecting pull rod fixedly connected to the rotating block, a first rotating seat rotatably connected to the connecting pull rod, a second rotating seat rotatably connected to the connecting bracket and the first fixed seat, a tension spring fixedly connected between the first rotating seat and the second rotating seat, a sliding rod slidably connected to the connecting bracket, a threaded rod threadedly connected to the connecting bracket, a knob fixedly connected to the threaded rod, a connecting frame fixedly connected to the sliding rod, and a sealing gasket fixedly connected to the connecting frame. The threaded rod is rotatably connected to the connecting frame, and the sliding rod is fixedly connected to the connecting frame. Pulling the connecting pull rod causes the rotating block to rotate, and rotating the knob causes the threaded rod to rotate, which in turn causes the connecting frame to move.

[0008] Preferably, the rotating block has a matching groove at a position relative to the first fixed rod, and the rotating block is slidably connected to the first fixed rod through the groove.

[0009] Preferably, the connecting frame has a limiting groove at the relative position of the threaded rod, and the threaded rod is rotatably connected to the groove.

[0010] Preferably, the heat exchange assembly includes a heat exchange box body fixedly connected to the mounting base plate, a first motor fixedly connected to the heat exchange box body, a rotating disk fixedly connected to the output end of the first motor, a second fixed rod fixedly connected to the rotating disk and slidably connected to the sliding rack on the heat exchange box body, a connecting block fixedly connected to the sliding rack, a rotating gear meshing with the sliding rack, and a guide vane fixedly connected to the rotating gear. The guide vane is rotatably connected to the heat exchange box body, and the second fixed rod is slidably connected to the connecting block. The first motor drives the rotating disk to rotate, and when the rotating disk rotates, it engages with the connecting block through the second fixed rod, causing the connecting block to slide.

[0011] Preferably, the heat exchanger body has a limiting groove at the relative position of the sliding rack, and the sliding rack is slidably connected to the groove.

[0012] Preferably, the connecting block has a groove for fitting at the relative position of the second fixed rod, and the second fixed rod is slidably connected to the groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. The incoming airflow is replaced by the converter valve body. Two sets of first fixed boxes alternately perform filtration. While one set is being maintained and replaced, the other set can maintain the smoothness of the filtration process, ensuring that the airflow remains of high quality throughout the process. This avoids airflow interruption or quality degradation due to equipment maintenance, and also effectively improves the reliability of the entire system and reduces the risk of system downtime caused by equipment failure.

[0015] 2. When the cold air enters the heat exchange box, it is guided by the sliding rack and the oscillating guide vanes, which ensure that the cold air is evenly distributed into the heat exchange box for heat exchange. This avoids the problem of concentrated cold air entering, which could cause a sharp drop in temperature in some areas while other areas may become too hot due to insufficient cold air.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 - Figure 8This utility model provides an embodiment of a hydraulic system cooling device, including a mounting base plate 1, a first fixed box 21 fixedly connected to the mounting base plate 1, a converter valve body 22 disposed outside the first fixed box 21, a first connecting pipe 23 fixedly connected to the first fixed box 21 and the converter valve body 22, a sliding frame 24 slidably connected to the first fixed box 21, a sealing assembly disposed on the first fixed box 21, a pre-filter plate 25 disposed on the sliding frame 24, a dust filter plate 26 disposed on the sliding frame 24, an activated carbon filter plate 27 disposed on the sliding frame 24, a centrifugal fan 28 fixedly connected to the mounting base plate 1, a second connecting pipe 29 fixedly connected between the centrifugal fan 28 and the first fixed box 21, and a heat exchanger disposed on the mounting base plate 1. The components, including the refrigeration box body 210 located between the heat exchange components and the centrifugal fan 28, are used in a system where the first fixed box 21 is sealed by a sealing component. The centrifugal fan 28 draws in outside air through the converter valve body 22 and the first connecting pipe 23 into the first fixed box 21. As the air passes through the three-layer sliding frame 24, larger impurities are filtered by the pre-filter plate 25, dust is filtered by the dust filter plate 26, and fine particles are filtered by the activated carbon filter plate 27. The air is then transported to the refrigeration box body 210 via the second connecting pipe 29. The refrigeration box body 210 utilizes a common technology in this field. During use, the low-temperature, low-pressure refrigerant inside the evaporator of the refrigeration box body 210 absorbs heat from the air, causing the air temperature to drop rapidly. Simultaneously, the refrigerant changes from a liquid to a gaseous state, completing the heat absorption process. Subsequently, the gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor, enters the condenser to release heat and turns back into a liquid state, and repeats the cycle to continuously cool the air entering the refrigeration box. The cooled air then enters the heat exchange components for further cooling and temperature exchange. When one side of the filter plate gradually becomes clogged, the air is replaced by periodically activating the converter valve body 22, allowing the air to enter the other set of first fixed boxes 21 through the first connecting pipe 23 on the other side for filtration. After the sealing components connected to the first set of first fixed boxes 21 are adjusted to release the restriction on the sliding frame 24, the sliding frame 24 is removed and replaced with the corresponding filter plate.

[0027] Please see Figure 1 - Figure 6In this embodiment, the first fixed box 21 has a storage groove at the relative position of the sliding frame 24. The sliding frame 24 is slidably connected to the groove. The groove stores and restricts the sliding of the sliding frame 24, preventing it from tilting during storage and affecting the airflow. The connected filter plate filters the air. The sealing assembly includes a first fixed seat 211 fixedly connected to the first fixed box 21, a connecting bracket 212 disposed on the first fixed seat 211, a first fixed rod 213 fixedly connected to the connecting bracket 212 and the first fixed seat 211, a rotating block 214 slidably connected to the first fixed rod 213, and a fixed block 214 fixedly connected to the rotating block 214. The following components are attached to block 214: a connecting rod 215, a first rotating seat 216 rotatably connected to the connecting rod 215, a second rotating seat 217 rotatably connected to the connecting bracket 212 and the first fixed seat 211, a tension spring 218 fixedly connected between the first rotating seat 216 and the second rotating seat 217, a sliding rod 219 slidably connected to the connecting bracket 212, a threaded rod 220 threadedly connected to the connecting bracket 212, a knob 221 fixedly connected to the threaded rod 220, a connecting frame 222 fixedly connected to the sliding rod 219, and a sealing gasket 223 fixedly connected to the connecting frame 222. The threaded rod 220 is rotatably connected to the connecting... On frame 222, sliding rod 219 is fixedly connected to connecting frame 222. Pulling connecting rod 215 drives rotating block 214 to rotate. Rotating knob 221 drives threaded rod 220 to rotate. The rotation of threaded rod 220 moves connecting frame 222. Sealing gasket 223 fits against first fixed box 21, sealing the sliding position of first fixed box 21 and restricting the sliding of sliding frame 24. This prevents air and dust from being sucked in from the gaps in the groove during filtration, and also prevents sliding frame 24 from moving during filtration, thus affecting the filter plate's filtration of air. Rotating block 214 has a suitable opening at the relative position of first fixed rod 213. The sliding groove is used, and the rotating block 214 is slidably connected to the first fixed rod 213 through the sliding groove. The sliding groove cooperates with the first fixed rod 213 to limit the sliding range of the rotating block 214 and prevent the rotating block 214 from sliding too much and disengaging from the connecting bracket 212, which would affect the restriction on the connection between the first fixed seat 211 and the connecting bracket 212. The connecting frame 222 has a limiting groove at the relative position of the threaded rod 220. The threaded rod 220 is rotatably connected to the groove. The groove restricts the connection between the threaded rod 220 and the connecting frame 222 and prevents the threaded rod 220 from disengaging from the connecting frame 222 when rotating, which would affect the subsequent adjustment of the sliding of the connecting frame 222.

[0028] Please see Figure 1 , Figure 2 , Figure 7 - Figure 8In this embodiment, the heat exchange assembly includes a heat exchange box body 31 fixedly connected to the mounting base plate 1, a first motor 32 fixedly connected to the heat exchange box body 31, a rotating disk 33 fixedly connected to the output end of the first motor 32, a second fixing rod 34 fixedly connected to the rotating disk 33, a sliding rack 35 slidably connected to the heat exchange box body 31, a connecting block 36 fixedly connected to the sliding rack 35, a rotating gear 37 meshing with the sliding rack 35, and a guide vane 38 fixedly connected to the rotating gear 37. The guide vane 38 is rotatably connected to the heat exchange box body 31, and the second fixing rod 34 is slidably connected to the connecting block 36. The first motor 32 drives the rotating disk 33 to rotate. When the rotating disk 33 rotates, it engages with the connecting block 36 through the second fixing rod 34, causing the connecting block 36 to slide. The guide vane 38 reciprocates. The movement guides the cold air entering the heat exchanger body 31, preventing the cold air from concentrating inside the heat exchanger body 31 and causing some areas of the heat exchanger to over-exchange heat while other areas experience insufficient heat exchange, thus affecting the overall heat exchange and cooling efficiency. The heat exchanger body 31 has a limiting groove at the relative position of the sliding rack 35, and the sliding rack 35 is slidably connected to the groove. The groove guides the sliding of the sliding rack 35, preventing it from tilting during sliding and affecting its meshing with the rotating gear 37. The connecting block 36 has an adaptation groove at the relative position of the second fixed rod 34, and the second fixed rod 34 is slidably connected to the groove. The sliding between the groove and the second fixed rod 34 restricts the movement of the second fixed rod 34, preventing it from disengaging from the connecting block 36 and affecting its ability to drive the sliding rack 35 to slide back and forth.

[0029] During operation, after the first fixed box 21 is sealed by the sealing gasket 223, the centrifugal fan 28 draws in external air through the converter valve body 22 and the first connecting pipe 23 into the first fixed box 21. As the air passes through the three-layer sliding frame 24, larger impurities are filtered by the pre-filter plate 25, dust is filtered by the dust filter plate 26, and finally fine particles are filtered by the activated carbon filter plate 27. The air is then transported to the refrigeration box body 210 via the second connecting pipe 29. The refrigeration box body 210 employs a common technique in the field. During operation, the low-temperature, low-pressure refrigerant inside the evaporator of the refrigeration box body 210 absorbs heat from the air, causing the air temperature to drop rapidly. Simultaneously, the refrigerant changes from a liquid to a gaseous state, completing the heat absorption process.Subsequently, the gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor, enters the condenser to release heat, and then reverts to a liquid state, repeating this cycle continuously to cool the air entering the refrigeration chamber. When the cooled air enters the heat exchanger body 31, the first motor 32 drives the rotating disk 33 to rotate. The rotation of the rotating disk 33 drives the second fixed rod 34 to rotate. The rotation of the second fixed rod 34, through its interaction with the connecting block 36, drives the sliding rack 35 to reciprocate. The sliding rack 35, through its interaction with the rotating disk 31... Gear 37 meshes, driving guide vane 38 to oscillate reciprocally to guide the cold air, preventing it from concentrating inside the heat exchanger body 31 and causing insufficient heat exchange in the outer areas. When external hydraulic oil enters the heat exchanger inside the heat exchanger body 31, it is cooled by contact with the cold air in the heat exchanger body 31 before being circulated out, thus completing the cooling process. When one filter plate gradually becomes clogged, the air is replaced by the periodically activated exchange valve body 22, which enters another set of filters through the first connecting pipe 23 on the other side. Filtering is performed inside a fixed box 21. Then, by pulling the connecting rod 215 connected to the first fixed box 21, the rotating block 214 is driven to rotate on the first fixed rod 213. As the rotating block 214 rotates, it causes the rotating block 214 on the other side to rotate, releasing the restriction on the connection between the connecting bracket 212 and the first fixed seat 211. The connecting bracket 212 is then removed, and the sliding frame 24 and the connected filter plate are taken out for replacement and maintenance. After completion, the sliding frame 24 and the filter plate are reinstalled inside the first fixed box 21, and then the connecting bracket 212 is placed back in place. After the first fixed seat 211 is mounted, the tension spring 218 provides tension to the first rotating seat 216, causing the connecting rod 215 to reset with the first rotating seat 216. This causes the rotating block 214 to rotate and then the rotating blocks 214 on both sides to press against each other, thus restricting the connection between the connecting bracket 212 and the first fixed seat 211. When the knob 221 is turned, the threaded rod 220 is rotated. When the threaded rod 220 rotates, it causes the connecting frame 222 to move. At the same time, the sealing gasket 223 moves towards the first fixed box 21 and seals the first fixed box 21 after it comes into contact with the first fixed box 21.

[0030] Through the above steps, the incoming airflow is replaced by the converter valve body 22, and the two sets of first fixed boxes 21 alternately perform the filtration work. While one set is being maintained and replaced, the other set can maintain the smoothness of the filtration work. This solves the problem that when the filter assembly is being maintained and the filter plate is being replaced, it will affect the cooling of the hydraulic oil, causing the hydraulic oil temperature to accumulate and not be cooled down in time, thus affecting the normal operation of the equipment.
