Description

Technical Field

[0001] This application relates to the field of lubrication equipment, and in particular to an oil-water separation tank device for a pipe cutting machine. Background Technology

[0002] Pipe cutting machines play a vital role in modern industrial production, especially in the processing of large-diameter steel pipes. Large-diameter steel pipes require high precision in both length and cut perpendicularity, making pipe cutting machines a common choice for many companies.

[0003] Currently, domestically produced large-diameter pipe cutting machines hold the steel pipe stationary while the cutting tool rotates and simultaneously feeds linearly to cut the pipe. Because of this type of machine, during pipe cutting, cooling water from the cutting tool enters the transmission box along the machine wall from the gap between the turntable and the tool box. As the transmission box gears cool the lubricating fluid, it flows back to the lubricating oil tank. Some of the water in the lubricating oil tank mixes with the lubricating oil and is pumped back into the gearbox for further processing.

[0004] Regarding the aforementioned technologies, if cooling water enters the gearbox along with the lubricating oil, it can easily affect the lubrication effect of the lubricating oil on the gearbox. Utility Model Content

[0005] In order to reduce the water in the lubricating oil and improve the lubrication effect, this application provides an oil-water separation tank device for a pipe cutting machine.

[0006] The oil-water separator tank device for a pipe cutting machine provided in this application adopts the following technical solution:

[0007] An oil-water separation tank device for a pipe cutting machine includes an oil storage tank. The oil storage tank has a separation chamber and an oil storage chamber. The oil storage tank is connected to a partition. The separation chamber and the oil storage chamber are separated by the partition. The separation chamber is used to communicate with the pipe cutting machine body, and the oil storage chamber is used to communicate with a pressure oil pump. The partition has a communication hole.

[0008] By adopting the above technical solution, when in use, the oil-water mixture enters the separation chamber, where it settles and separates into layers. As the liquid level rises, the lubricating oil in the upper layer enters the oil storage chamber through the connecting hole, thereby separating the lubricating oil from the water and minimizing the possibility of water following the lubricating oil into the oil pump and then into the gearbox, thus improving the lubrication effect of the lubricating oil on the gearbox.

[0009] Optionally, the separation chamber is connected to a drain pipe, which is located below the connecting hole. The drain pipe is connected to an opening and closing device for opening or closing the drain pipe. The oil storage tank is connected to a water level detection component for detecting the water level in the separation chamber.

[0010] The above-mentioned technical solution is typically used so that when the water level detection component detects that the water level in the separation chamber is close to the connecting hole, the opening and closing component opens the drain pipe, allowing the water in the lower layer to be discharged. This reduces the possibility of water entering the gearbox along with the lubricating oil, thereby improving the lubrication effect of the lubricating oil on the gearbox.

[0011] Optionally, the water level detection component includes an oil receiving tank and a float. The oil receiving tank is connected to the separation chamber, and the drain pipe is connected to the separation chamber through the oil receiving tank. The float is located inside the oil receiving tank and is used to float up and down with the water level. A distance sensor is connected to the top of the oil receiving tank. The opening and closing element is a first valve. The distance sensor is electrically connected to a controller, and the controller is electrically connected to the first valve. The distance sensor is used to detect the distance between the float and the top of the oil receiving tank and output a distance value. The controller is used to receive the distance value and compare it with a preset value range. When the distance value received by the controller is less than the minimum preset value, the controller controls the first valve to open. When the distance value received by the controller is greater than the maximum preset value, the controller controls the first valve to close.

[0012] By adopting the above technical solution, after the oil-water mixture enters the separation chamber and settles and separates into layers, the oil-water mixture enters the oil receiving tank. The water level in the oil receiving tank rises with the water level in the separation chamber, and the float rises with the water level. When the distance value received by the controller is less than the minimum preset value, the controller controls the first valve to open the drain pipe, so that the water in the separation chamber is discharged. This facilitates the timely discharge of water from the separation chamber and reduces the possibility of water entering the oil storage chamber. When the distance value received by the controller is greater than the maximum preset value, the controller controls the first valve to baffle the drain pipe, reducing the possibility of lubricating oil being discharged from the separation chamber.

[0013] Optionally, a guide rod is connected inside the oil tank, with the top of the guide rod positioned near the distance sensor, and the float is slidably sleeved on the guide rod.

[0014] By adopting the above technical solution, when the water level in the oil tank rises, the float moves along the guide rod and gradually approaches the distance sensor, so that the distance sensor can detect the distance between the float and the top of the oil tank.

[0015] Optionally, the separation chamber is connected to a return oil pipe, and the separation chamber is connected to the pipe cutting machine body through the return oil pipe. A guide and a first filter are connected inside the separation chamber. The guide is used to guide the oil-water mixture discharged from the return oil pipe to the first filter, and the first filter is used to filter impurities in the oil-water mixture.

[0016] By adopting the above technical solution, the oil-water mixture discharged from the return oil pipe enters the first filter element through the guide element. The first filter element performs preliminary filtration of impurities in the oil-water mixture, thereby reducing impurities in the oil-water mixture and facilitating the recovery of lubricating oil.

[0017] Optionally, the flow guide is a guide plate, which is located above the connecting hole. The first filter element is provided in a plurality of manners. The first filter element includes a first filter barrel with an opening at the top. The plurality of first filter barrels are all connected to the guide plate. The guide plate is used to guide the oil-water mixture into the plurality of first filter barrels.

[0018] By adopting the above technical solution, the oil-water mixture is discharged to the guide plate through the oil return pipe, and enters the first filter barrel along the top of the guide plate for filtration. The filtered oil-water mixture enters the separation chamber, and the first filter element is provided in several ways, thereby accelerating the filtration efficiency of the oil-water mixture and improving the filtration effect.

[0019] Optionally, a baffle is connected to the top of the guide plate, the baffle being used to prevent the oil-water mixture at the top of the guide plate from entering the separation chamber.

[0020] By adopting the above technical solution and adding a baffle, the amount of oil-water mixture that has not passed through the first filter element directly enters the separation chamber, thereby reducing impurities in the separation chamber.

[0021] Optionally, the guide plate has several mounting holes, and each of the first filter barrels is respectively inserted into each mounting hole. A support plate is connected to the top of the first filter barrel, and the support plate contacts the top of the guide plate. A handle is connected to the top of the support plate.

[0022] By adopting the above technical solution, when there are impurities in the first filter canister, the operator can remove the first filter canister from the installation hole, which makes it easier for the operator to clean or replace the first filter canister. A handle is also added to make it easier for the operator to pick up the first filter canister.

[0023] Optionally, the oil storage chamber is connected to an oil inlet pipe, and the oil inlet pipe is connected to a second filter barrel, which is located inside the oil storage chamber.

[0024] By adopting the above technical solution, the oil-water mixture is allowed to stand and separate into layers in the separation chamber. The upper layer of lubricating oil enters the oil storage chamber through the connecting hole. The lubricating oil in the oil storage chamber enters the oil inlet pipe through the second filter barrel. The second filter barrel further filters the lubricating oil, thereby further reducing impurities in the lubricating oil and facilitating the recovery of the lubricating oil.

[0025] Optionally, the second filter can be detachably connected to the oil inlet pipe.

[0026] By adopting the above technical solution, the second filter can be detachably connected to the oil inlet pipe, which facilitates cleaning and replacement of the second filter can.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During use, the oil-water mixture enters the separation chamber, where it settles and separates into layers. As the liquid level rises, the lubricating oil in the upper layer enters the oil storage chamber through the connecting hole. When the water level detection component detects that the water level in the separation chamber is close to the connecting hole, the first valve opens the drain pipe, allowing the water in the lower layer to be discharged. This reduces the amount of water entering the oil pump and improves the lubrication effect of the lubricating oil.

[0029] 2. After the oil-water mixture enters the separation chamber and settles and separates into layers, the oil-water mixture enters the oil receiving tank. The water level in the oil receiving tank rises with the water level in the separation chamber, and the float rises with the water level. When the distance sensor detects that the distance between the top of the oil receiving tank and the float has decreased, the first valve opens and drains the water in the separation chamber. This allows the operator to drain the water in the separation chamber in a timely manner and reduces the possibility of water entering the oil storage chamber.

[0030] 3. The oil-water mixture is discharged to the top of the guide plate through the oil return pipe, and then enters the first filter barrel for filtration along the top of the guide plate. The filtered oil-water mixture enters the separation chamber, and the first filter element is provided in several places to accelerate the filtration efficiency of the oil-water mixture and improve the filtration effect.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses an oil-water separator tank device for a pipe cutting machine. (Refer to...) Figure 1 , Figure 2 and Figure 3 An oil-water separation tank device for a pipe cutting machine includes an oil storage tank 100 with an opening at the top. The oil storage tank 100 contains a separation chamber 200 and an oil storage chamber 300. A partition 110 is connected to the inner wall of the oil storage tank 100, and the partition 110 is vertically arranged with both ends connected to the inner wall of the oil storage tank 100 along its length. The separation chamber 200 and the oil storage chamber 300 are separated by the partition 110. The separation chamber 200 is equipped with a water level detection component 500, which is used to detect the water level within the separation chamber 200. The oil-water mixture enters the separation chamber 200, settles, and separates into layers. The upper layer of lubricating oil enters the oil storage chamber 300 through a connecting hole 111, thereby separating the oil-water mixture and improving the lubricating effect of the lubricating oil.

[0038] Reference Figure 1 and Figure 3 The top of the separation chamber 200 is connected to a return oil pipe 120, which is used to connect to the pipe cutting machine body. The bottom of the oil storage chamber 300 is connected to an oil inlet pipe 130, which is used to connect to the oil pump. The partition 110 has several connecting holes 111, which are located at the top of the partition 110 and are spaced apart along the length of the partition 110. The connecting holes 111 connect the separation chamber 200 and the oil storage chamber 300.

[0039] Reference Figure 1 and Figure 3A guide plate 210 is connected inside the separation chamber 200, and the guide plate 210 is located above the connecting hole 111. The guide plate 210 is horizontally arranged, and its length direction is consistent with the length direction of the oil tank 100. One end of the guide plate 210 in the length direction is connected to the inner wall of the oil tank 100, and the other end of the guide plate 210 in the width direction is connected to the inner wall of the oil tank 100. A baffle 211 is connected to the top of the guide plate 210. The baffle 211 is L-shaped, and both ends of the baffle 211 are connected to the inner wall of the oil tank 100.

[0040] Reference Figure 1 and Figure 3 The oil return pipe 120 has its oil outlet located above the guide plate 210. The guide plate 210 has two mounting holes 212, each containing a first filter element 400. The first filter element 400 includes a first filter barrel 410 and a magnetic rod 420. The first filter barrel 410 is vertically oriented with an opening at its top. The magnetic rod 420's length is aligned with the vertical direction, and its bottom end is connected to the inner wall of the bottom of the first filter barrel 410. The first filter barrel 410 has several first filter holes 411 on its circumference.

[0041] Reference Figure 3 and Figure 4 A support plate 412 is connected to the top of the first filter barrel 410. The support plate 412 is annular, and its central axis is collinear with that of the first filter barrel 410. A handle 413 is connected to the top of the support plate 412. A connecting groove 213 for placing the support plate 412 is provided on the inner wall of the mounting hole 212. The connecting groove 213 is annular. When the support plate 412 is embedded in the connecting groove 213, the top surface of the support plate 412 and the top surface of the guide plate 210 are on the same plane. The addition of the first filter element 400 reduces impurities in the mixture of lubricating oil and water, facilitates the recovery of lubricating oil, and the first filter barrel 410 is detachably connected to the guide plate 210, which facilitates cleaning and replacement of the first filter barrel 410.

[0042] Reference Figure 1 and Figure 3 The water level detection component 500 includes an oil receiving tank 510 and a float 520. The oil receiving tank 510 is vertically arranged, and a connecting pipe 511 is connected to the bottom of the oil receiving tank 510. The other end of the connecting pipe 511 is connected to the bottom of the separation chamber 200, and a second valve 512 is connected to the connecting pipe 511. A drain pipe 140 is connected to the bottom of the oil receiving tank 510, and the drain pipe 140 is connected to the separation chamber 200 through the oil receiving tank 510. A return pipe 513 is connected to the top of the oil receiving tank 510, and the other end of the return pipe 513 is connected to the separation chamber 200. The connection point between the return pipe 513 and the separation chamber 200 is located above the connecting hole 111.

[0043] Reference Figure 3A guide rod 530 is connected to the inner wall of the oil receiving tank 510. The length direction of the guide rod 530 is consistent with the vertical direction. A float 520 is slidably sleeved on the guide rod 530 and is used to float up and down with the water surface. A distance sensor, which is an infrared distance sensor, is connected to the top of the oil receiving tank 510. The distance sensor is electrically connected to a controller, which is a microcontroller. The controller is electrically connected to the first valve 141. The distance sensor is used to detect the distance between the float 520 and the top of the oil receiving tank 510 and outputs the distance value. The controller is used to receive the distance value and compare it with a preset value range. When the distance value is less than the minimum preset value, the controller controls the first valve 141 to open; when the distance value is greater than the maximum preset value, the controller controls the first valve 141 to close. When the water level in the separation chamber 200 rises and approaches the connecting hole 111, the water level in the oil receiving tank 510 rises accordingly and causes the float 520 to float. When the distance value received by the controller is less than the minimum preset value, the controller opens the first valve 141, so that the water in the separation chamber 200 and the oil receiving tank 510 are discharged, thereby reducing the water in the separation chamber 200 and reducing the amount of water entering the oil storage chamber 300.

[0044] Reference Figure 1 and Figure 2 A second filter barrel 310 is provided inside the oil storage chamber 300. The end of the oil inlet pipe 130 furthest from the oil pump passes through the inner wall of the oil storage chamber 300 and is located within the oil storage chamber 300. Several second filter holes 311 are formed around the periphery of the second filter barrel 310. A nut 312 is connected to one end of the second filter barrel 310 along its length; the nut 312 is threaded onto the oil inlet pipe 130, which communicates with the second filter barrel 310. The addition of the second filter barrel 310 further reduces impurities in the lubricating oil and improves the lubrication effect.

[0045] The implementation principle of the oil-water separation tank device for a pipe cutting machine according to an embodiment of this application is as follows: The oil-water mixture flows through the return oil pipe 120 to the top of the guide plate 210. The oil-water mixture enters the first filter tank 410 along the guide plate 210. After filtration, the oil-water mixture enters the separation chamber 200. The oil-water mixture settles and separates in the separation chamber 200. The second valve 512 is opened, allowing the liquid in the separation chamber 200 to enter the receiving tank 510. As the liquid level in the separation chamber 200 rises, the upper layer of lubricating oil enters the oil storage chamber 300 through the connecting hole 111. At the same time, the water level in the receiving tank 510 rises along with the water level in the separation chamber 200. The rise in the water level in the receiving tank 510 causes the float ball 520 to float. When the distance value detected by the distance sensor is less than the minimum preset value, the controller opens the first valve 141, allowing the water in the separation chamber 200 and the receiving tank 510 to be discharged. When the distance value is greater than the maximum preset value, the controller closes the first valve 141. This reduces the amount of water in the separation chamber 200 and minimizes the entry of water into the oil reservoir 300, thereby improving the lubrication effect of the lubricating oil. The lubricant in the oil reservoir 300 is pumped into the gearbox via an oil pump to lubricate the gearbox.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
