Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder processing, specifically relating to a device for cleaning sludge from the inner wall of a hydraulic cylinder after honing. Background Technology

[0002] As the core actuator in a hydraulic system, the hydraulic cylinder requires precision machining processes such as honing during its manufacturing to ensure the dimensional accuracy and surface quality of its inner wall.

[0003] However, after honing, a large amount of sludge, metal shavings, and abrasive particles often remain on the inner wall of the cylinder. If the cleaning is not thorough, it will directly affect the performance and life of the cylinder, and may even lead to hydraulic system failure.

[0004] Currently, when using high-pressure water guns to clean the inner walls of hydraulic cylinders, the waste liquid is directly discharged after cleaning, which pollutes the environment and increases operating costs. Even if some equipment is equipped with a simple filtration device, it can only filter large particles and cannot remove fine impurities and floating oil in the waste liquid. If it is directly recycled, it will cause secondary pollution to the inner walls of the hydraulic cylinder. Furthermore, the lack of a heating function for the cleaning agent means that the room temperature cleaning agent has limited ability to dissolve and remove sludge, resulting in a significant decrease in cleaning effect.

[0005] Therefore, we propose a device for cleaning sludge from the inner wall of a hydraulic cylinder after honing to solve the above problems. Utility Model Content

[0006] In response to the current industry practice of using high-pressure water guns to clean the inner wall of hydraulic cylinders, which cannot effectively filter the cleaning agent, cannot be directly recycled, lack a heating function for the cleaning agent, and have limited ability to dissolve and remove sludge at room temperature, resulting in a significant decrease in cleaning effect, this utility model provides a device for cleaning sludge from the inner wall of hydraulic cylinders after honing.

[0007] The solution adopted by this utility model to solve its technical problem is: a device for cleaning the sludge on the inner wall of a cylinder after honing, including a frame, a rinsing box, a heating water tank, a high-pressure water pump, a filter circulation treatment unit, and at least one high-pressure water gun. The rinsing box is fixedly installed on the top of the frame, and its inner bottom is used to place the cylinder to be cleaned. The heating water tank, high-pressure water pump, and filtration and circulation treatment unit are respectively installed in the frame. The liquid extraction end of the high-pressure water pump is connected to the liquid outlet of the heating water tank through the liquid extraction pipe. The liquid outlet end of the high-pressure water pump and the liquid inlet end of the water gun are connected through the liquid outlet hose. One end of the rinsing tank is open, allowing the cleaning agent inside the rinsing tank to flow into the filtration circulation unit. The outlet of the filtration circulation unit is connected to the inlet of the heating water tank.

[0008] Preferably, a baffle plate is welded and fixed to the open end of the rinsing box, and the baffle plate has a liquid outlet hole.

[0009] Preferably, the filtration circulation process includes a filter box for coarse filtration of the cleaning agent and a filter sedimentation tank for secondary filtration and sedimentation. The filter box is fixedly installed on the left side of the baffle plate to receive the cleaning agent flowing out of the outlet hole. The bottom outlet hole of the filter box is connected to the inlet of the filter sedimentation tank through a return pipe. The outlet of the filter sedimentation tank is connected to the inlet of the heating water tank through a pipe.

[0010] Preferably, it also includes a steel belt oil separator, which is positioned above the filtration and sedimentation tank, with its oil-removing steel belt submerged below the liquid surface of the filtration and sedimentation tank to remove floating oil from the liquid surface.

[0011] Preferably, the rinsing tank is inclined to guide the cleaning agent to flow into the outlet hole of the baffle plate.

[0012] Preferably, there are two high-pressure water guns, both of which are connected to the high-pressure water pump via a liquid outlet hose, and can be used independently to rinse the sludge on the inner wall of the oil cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The waste liquid after cleaning is first coarsely filtered through a filter box to remove large particles such as metal shavings, and then enters a filter sedimentation tank for secondary filtration and sedimentation to remove fine impurities. At the same time, a steel belt oil remover is used to remove floating oil on the liquid surface, ensuring that the purified cleaning agent meets the recycling standards, greatly reducing the amount of new cleaning agent to be added, reducing operating costs, and avoiding environmental pollution caused by direct discharge of waste liquid.

[0014] 2. By setting up a heating water tank, this utility model can heat the cleaning agent to a suitable temperature, enhance its ability to dissolve and peel off oil sludge, effectively solve the problem of poor cleaning effect of room temperature cleaning agents, and improve the cleanliness and cleaning efficiency of the inner wall of the oil cylinder.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1-3 This utility model provides a technical solution for a device for cleaning sludge from the inner wall of a hydraulic cylinder after honing: Example 1: according to Figure 1-3 As shown, it includes a frame 8, a rinsing tank 1, a heating water tank 3, a high-pressure water pump 7, a filtration and circulation treatment unit, and at least one high-pressure water gun 6. The frame 8 is made of thickened steel and has a painted layer on its outer surface. The overall welded shape of the frame 8 is designed as a right-angled trapezoidal structure.

[0019] One end of the rinsing tank 1 is open, and a baffle plate 9 is welded and fixed to the open end of the rinsing tank 1. The baffle plate 9 has a liquid outlet hole 91. Under the action of the baffle plate 9, the waste liquid in the rinsing tank 1 is concentrated and flows out through the liquid outlet hole 91. The rinsing tank 1 is fixedly installed on the sloping top of the frame 8. Its inner bottom is used to place the oil cylinder to be cleaned. The rinsing tank 1 is set at an angle to guide the cleaning agent to flow to the liquid outlet hole 91 of the baffle plate 9.

[0020] The heating water tank 3, high-pressure water pump 7, and filter circulation treatment unit are respectively installed in the frame 8. The heating water tank 3 is made of 304 stainless steel and its maximum heating temperature is 80℃. The heating water tank 3 is designed to prevent dry burning. When the liquid level in the heating water tank 3 is low, the buzzer in the distribution box will sound a warning and the equipment will stop. By setting up the heating water tank 3, the cleaning agent can be heated to a suitable temperature, which enhances its ability to dissolve and peel off sludge, effectively solving the problem of poor cleaning effect of room temperature cleaning agents, and improving the cleanliness and cleaning efficiency of the inner wall of the oil cylinder.

[0021] The liquid extraction end of the high-pressure water pump 7 is connected to the liquid outlet of the heating water tank 3 through the liquid extraction pipe 12, and the liquid outlet end of the high-pressure water pump 7 and the liquid inlet end of the water gun 6 are connected through the liquid outlet hose 11.

[0022] The filtration and circulation process includes a steel belt degreasing machine 5, a filter box 2 for coarse filtration of the cleaning agent, and a filter sedimentation tank 4 for secondary filtration and sedimentation. The filter box 2 is fixedly installed on the left side of the baffle plate 9 to receive the cleaning agent flowing out of the liquid outlet 91. The liquid outlet 91 at the bottom of the filter box 2 is connected to the liquid inlet of the filter sedimentation tank 4 through the return pipe 10. The waste liquid after cleaning is first coarsely filtered by the filter box 2 to remove large particles such as metal debris, and then enters the filter sedimentation tank 4 for secondary filtration and sedimentation to remove fine impurities.

[0023] The steel belt oil separator 5 is installed above the filter sedimentation tank 4. Its oil-removing steel belt is immersed below the liquid surface of the filter sedimentation tank 4 to remove floating oil from the liquid surface, ensuring that the purified cleaning agent meets the recycling standards, greatly reducing the amount of new cleaning agent to be added, reducing operating costs, and avoiding environmental pollution caused by direct discharge of waste liquid. During use, the filter box 2 and the steel belt oil separator 5 should be cleaned at least once per shift to prevent impurities from accumulating and causing equipment damage.

[0024] The outlet of the filtration sedimentation tank 4 is connected to the inlet of the heating water tank 3 through a pipe, so that the cleaning agent after secondary filtration flows to the heating water tank 3.

[0025] In practical use, the oil sludge cleaning device for the inner wall of a honing cylinder of this utility model first adds sufficient cleaning agent to the heating water tank 3 to ensure that the liquid level is within a safe range to avoid dry burning. Then, the heating function of the heating water tank 3 is turned on to heat the cleaning agent to a preset suitable temperature (e.g., 50-80℃) to enhance the cleaning effect. During the heating process, the equipment will automatically monitor the liquid level. If the liquid level is too low, the buzzer will sound an alarm and the machine will automatically stop. Place the oil cylinder to be cleaned at the bottom of the flushing tank 1. After the cleaning agent reaches the required temperature, start the high-pressure water pump 7. The high-pressure water pump 7 will draw the heated cleaning agent from the heating water tank 3 and deliver it to the high-pressure water gun 6 through the liquid outlet hose 11. The operator holds the high-pressure water gun 6 and inserts the nozzle into the oil cylinder to be cleaned, aiming at the oil sludge on the inner wall of the oil cylinder for all-round, close-range spraying. The waste liquid generated during rinsing is guided by the inclined bottom of the rinsing tank 1 to flow towards the baffle plate 9 and into the filter box 2 through the liquid outlet 91. After coarse filtration, the liquid enters the filter sedimentation tank 4 through the return pipe 10. In the filter sedimentation tank 4, fine impurities further settle. At the same time, the steel belt degreasing machine 5 continues to work. Its steel belt, which is immersed in the liquid surface, absorbs and scrapes off the floating oil on the liquid surface, thereby achieving deep purification of the cleaning agent. The cleaning agent, after being filtered, settled, and purified by oil removal, flows back to the heating water tank 3 through a pipeline to replenish the water source and achieve recycling.

[0026] Example 2: Based on Example 1, the difference is as follows: there are two high-pressure water guns 6, and both high-pressure water guns 6 are connected to the high-pressure water pump 7 through the liquid outlet hose 11, and can be used independently to rinse the oil sludge on the inner wall of the oil cylinder.

[0027] Example 3: Based on Embodiment 1, the differences are as follows: a pad block is placed at the bottom of the rinsing tank 1. The pad block can be replaced according to the cylinder diameter. The top of the pad block has a groove to support the cylinder to be cleaned and prevent the cylinder from directly contacting the bottom of the rinsing tank 1. This device is suitable for a maximum cylinder diameter of Φ530mm and a maximum length of 3000mm.
