Description

Technical Field

[0001] This utility model relates to the field of skid-mounted compressor technology, specifically a skid-mounted device for hydraulic oil-driven compressor pressurization and re-injection. Background Technology

[0002] Skid-mounted equipment refers to a set of equipment where all parts are fixed to a common base. The base is usually made of channel steel or I-beams, and can be moved and installed using pry bars, hence the name "skid-mounted" equipment. Skid-mounted equipment is mostly small, but with the widespread use of large and medium-sized lifting equipment and the development of transportation systems, the proportion of large and medium-sized skid-mounted equipment is constantly increasing.

[0003] For example, the announcement number CN216767691U discloses a compressor skid-mounted structure, including a skid-mounted assembly, including a placement box and a shield plate disposed on the top of the placement box; and a protective assembly disposed inside the skid-mounted assembly, including a first integrated plate, a drying plate disposed on the top of the first integrated plate and a placement platform disposed on the top of the drying plate.

[0004] The device described in the above application is equipped with protective components and skid-mounted components. By mounting the compressor on a placement platform, the internal drying plate absorbs moisture from the gas. By setting the first integrated plate and the placement platform, the compressor is not directly installed at the bottom of the placement box. This alleviates the problems of some skid-mounted compressors where the working environment was not considered during the compressor installation process, resulting in the compressor casing being in a humid environment for a long time, causing corrosion. At the same time, the humid environment can easily cause circuit aging and poor contact. However, when the skid-mounted compressor is working, the compressor cylinder will experience a sharp increase in temperature due to piston friction and air compression. Excessive temperature will cause abnormal wear of the equipment, reduce its service life, and easily cause safety hazards. Therefore, there is an urgent need in the market to develop a skid-mounted device for hydraulic oil-driven compressor pressurization and reinjection to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a skid-mounted device for boosting and reinjecting hydraulic oil into a compressor, in order to solve the problem mentioned in the background art that when the skid-mounted compressor is working, the temperature of the compression cylinder will rise sharply due to piston friction and air compression. The excessively high temperature will cause abnormal wear of the equipment, reduce its service life, and easily cause safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a skid-mounted device for boosting and reinjecting hydraulic oil-driven compressors, comprising a control box, an air accumulator, a cylinder, and a radiator mounted on a base. A heat dissipation shroud is fixedly mounted on the outside of the cylinder, and cooling water is disposed inside the heat dissipation shroud. A heat dissipation pipe is disposed inside the radiator, with one end of the heat dissipation pipe connected to the heat dissipation shroud. A water pump is disposed on the base, and the end of the heat dissipation pipe away from the heat dissipation shroud is connected to the input end of the water pump. An outlet pipe is disposed at the output end of the water pump and connected to the heat dissipation shroud. A cooling fan is disposed inside the radiator.

[0007] The above technical solution utilizes a heat sink to enclose the cylinder and injects cooling water inside the heat sink. The cooling water flows between the radiator and the heat sink via a water pump, and the radiator cools the cooling water. The cooling water is then used to dissipate heat from the cylinder, thereby controlling the cylinder's operating temperature, preventing overheating, improving the stability of the compressed air operation, avoiding abnormal wear caused by excessive cylinder temperature, and extending the service life.

[0008] In a preferred embodiment, the present invention can be further configured such that: both ends of the hydraulic cylinder are provided with connectors, an oil pump is fixedly installed on the base, and the oil pump is connected to the hydraulic cylinder through an oil pipe.

[0009] Through the above technical solution, the oil pump operates in both forward and reverse directions to deliver oil to the hydraulic cylinder.

[0011] In a preferred embodiment, the present invention can be further configured such that: one end of the cylinder is fixedly connected to a converter head, the converter head is respectively connected to an intake pipe and an exhaust pipe, the intake end of the intake pipe is fixedly connected to a filter head, and the output end of the exhaust pipe is connected to an air storage tank through an air pipe.

[0012] By using the above technical solution and the filter head, impurities in the air can be effectively prevented from entering the cylinder, and flammable and explosive gases in the air can be prevented from entering the cylinder, thus improving the protection effect of the cylinder and preventing flammable and explosive gases from entering the cylinder and causing an explosion, thereby improving safety.

[0013] In a preferred embodiment, the present invention can be further configured as follows: a first plug disc is provided inside the air intake pipe, a first connecting rod is fixedly connected to one side of the first plug disc, a first pressure plate is fixedly connected to one end of the first connecting rod away from the first plug disc, and a first spring is provided on one side of the first pressure plate.

[0025] Please see Figure 1 and Figure 2 An embodiment of this utility model provides a skid-mounted device for boosting and reinjecting hydraulic oil-driven compressors, comprising a control box 2, an air tank 3, a cylinder 9, and a radiator 14 mounted on a base 1. A heat sink 10 is fixedly mounted on the outside of the cylinder 9, and cooling water is provided inside the heat sink 10. A heat dissipation pipe 16 is provided inside the radiator 14, with one end of the heat dissipation pipe 16 connected to the heat sink 10. A water pump 15 is mounted on the base 1, and the end of the heat dissipation pipe 16 away from the heat sink 10 is connected to the input end of the water pump 15. A water outlet pipe 17 is provided at the output end of the water pump 15 and connected to the heat sink 10. A cooling fan 19 is provided inside the radiator 14.

[0026] Please see Figure 1 Both ends of the hydraulic cylinder 4 are equipped with connectors, and an oil pump 7 is fixedly installed on the base 1. The oil pump 7 is connected to the hydraulic cylinder 4 through an oil pipe.

[0027] Please see Figure 1 A hydraulic cylinder piston 5 is slidably connected inside the hydraulic cylinder 4, and a hydraulic rod 6 is fixedly connected to one side of the hydraulic cylinder piston 5. A pneumatic cylinder piston 18 is slidably connected inside the pneumatic cylinder 9, and a push-pull rod 8 is fixedly connected to one side of the pneumatic cylinder piston 18. The hydraulic rod 6 and the push-pull rod 8 are fixedly connected.

[0028] Please see Figure 1 One end of the cylinder 9 is fixedly connected to a converter head 11, and an intake pipe 12 and an exhaust pipe 20 are respectively connected to the converter head 11. The intake end of the intake pipe 12 is fixedly connected to a filter head 13, and the output end of the exhaust pipe 20 is connected to the air storage tank 3 through an air pipe.

[0029] Please see Figure 3 The intake pipe 12 is provided with a first stopper 21. A first connecting rod 22 is fixedly connected to one side of the first stopper 21. A first pressure plate 24 is fixedly connected to the end of the first connecting rod 22 away from the first stopper 21. A first spring 23 is provided on one side of the first pressure plate 24.

[0031] Working principle: During use, the oil pump 7 delivers hydraulic oil to the hydraulic cylinder 4, driving the cylinder piston 5 to reciprocate inside the hydraulic cylinder 4. The cylinder piston 5 drives the push-pull rod 8 to reciprocate via the hydraulic rod 6, thereby driving the cylinder piston 18 to reciprocate inside the cylinder 9. When the cylinder piston 18 is in the intake stroke, the first stopper 21 moves inward, and the second stopper 25 closes the exhaust pipe 20 passage, allowing air to enter the cylinder 9. When the cylinder piston 18 is in the compression stroke, the first stopper 21 closes the intake pipe 12 passage, and the second stopper 25 moves outward, allowing compressed air to enter the air storage tank 3 through the exhaust pipe 20 for compression, thus completing the air compression work. At the same time, the water pump 15 draws the cooled water from the heat dissipation pipe 16 and injects it into the heat dissipation cover 10 to cool the cylinder 9. The hot water will re-enter the heat dissipation pipe 16, be cooled by the cooling fan 19, and then be injected back into the heat dissipation cover 10, thus achieving continuous cooling of the cylinder 9.
