Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to an oil tank for a sheet metal cleaning machine. Background Technology

[0002] In automobile production, sheet metal cleaning is a crucial pretreatment process. Its main function is to provide a clean and contamination-free metal surface for subsequent critical processes such as stamping, welding, and painting. Problems caused by incomplete cleaning are often hidden and only manifest later, with extremely high repair costs; therefore, its importance cannot be ignored.

[0003] However, the oil tanks used in existing sheet metal cleaning machines often fail to effectively purify the returned oil, resulting in a high level of impurities in the supplied cleaning oil. This leads to frequent clogging of the filter elements in the cleaning machine's filtration system, shortening their lifespan. Furthermore, the high cost of the filter elements in the cleaning machine's filtration system adds significant procurement costs for OEMs. Utility Model Content

[0004] To address the aforementioned issues, this application provides an oil tank for a sheet metal cleaning machine that not only effectively ensures the cleanliness of the cleaning oil but also has low operating costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An oil tank for a sheet metal cleaning machine includes an oil tank body, a first partition and a second partition that sequentially divide the internal space of the oil tank body into a dirty oil tank, an intermediate oil tank and a clean oil tank in one direction.

[0007] The first partition plate is provided with an oil passage hole, and a filter component is provided at the oil passage hole;

[0008] The second partition is provided with a first overflow port;

[0009] A filter pipe is provided between the intermediate oil tank and the clean oil tank, and a first oil pump and a first filter are provided on the filter pipe.

[0010] Furthermore, the first filter is located outside the tank body.

[0011] Furthermore, the inlet end of the filter pipe extends to the bottom of the intermediate oil tank, and the outlet end of the filter pipe extends to the bottom of the clean oil tank.

[0012] Furthermore, the filter component includes a first adsorption device and a filter element, wherein the first adsorption device is located on the inlet side of the oil passage, and the filter element is located on the outlet side of the oil passage.

[0013] Furthermore, the filter element includes two frame plates, and a filter screen is disposed between the two frame plates.

[0014] Furthermore, a mounting bracket is provided above the first adsorption device, and the mounting bracket is connected to the first adsorption device via a pull rod. An avoidance hole is provided on the upper side of the oil tank body, and the first adsorption device extends downward through the avoidance hole into the interior of the oil tank body. The mounting bracket blocks the avoidance hole.

[0015] Furthermore, a second oil pump and a second filter are provided on the oil supply line used to connect the oil tank and the cleaning components of the cleaning machine.

[0016] Furthermore, the intermediate oil tank is equipped with several second adsorption devices.

[0017] Furthermore, the first partition is provided with a second overflow port.

[0018] Furthermore, heaters are installed in the dirty oil tank, intermediate oil tank, and clean oil tank, and a temperature sensor is installed in the clean oil tank.

[0019] The beneficial effects of this utility model are:

[0020] 1. The oil tank of the sheet metal cleaning machine provided in this application is divided into a dirty oil tank, an intermediate oil tank, and a clean oil tank by a first partition and a second partition. A filter component is installed at the oil passage hole of the first partition between the dirty oil tank and the intermediate oil tank. By setting the first partition, large impurities can be allowed to settle in the dirty oil tank, achieving a primary impurity removal effect. By setting the filter component at the oil passage hole, large iron filings and lint brought in by the sheet metal can be adsorbed and blocked, achieving a secondary impurity removal effect and improving the filtration and cleaning effect.

[0021] 2. The oil tank of the sheet metal cleaning machine provided in this application uses a first oil pump to draw oil from the intermediate oil tank, and after passing through the first filter of the bypass, it returns to the clean oil tank, thus realizing the third impurity removal.

[0022] 3. The sheet metal cleaning machine oil tank provided in this application embodiment has a first overflow port at the upper end of the second partition. On the one hand, in the event of an accident with the second oil pump or a mismatch between the inlet and outlet oil flow rates causing the oil level in the clean oil tank to be too high, the cleaning oil can be returned to the intermediate oil tank from the first overflow port, preventing the cleaning oil from overflowing. On the other hand, the second partition can separate the intermediate oil tank and the clean oil tank, preventing the cleaning oil in the clean oil tank from mixing with the cleaning oil in the intermediate oil tank or the dirty oil tank, thereby ensuring its cleanliness.

[0023] 4. The oil tank of the sheet metal cleaning machine provided in this application embodiment can perform three purification treatments on the cleaning oil, effectively ensuring the cleanliness of the cleaning oil and thus ensuring the cleaning effect of the sheet metal.

[0024] 5. The oil tank of the sheet metal cleaning machine provided in this application embodiment does not require frequent filter replacement compared with the traditional oil tank of the cleaning machine, which effectively reduces the cost of use while ensuring the purification effect of the cleaning oil.

[0042] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0043] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0044] like Figure 1 and Figure 2 As shown, an oil tank for a sheet metal cleaning machine includes an oil tank body. A first partition 13 and a second partition 14 are disposed within the oil tank body. The first partition 13 and the second partition 14 sequentially divide the internal space of the oil tank body in one direction into a dirty oil tank 151, an intermediate oil tank 152, and a clean oil tank 153. According to... Figure 1 In the coordinate system shown, the first partition 13 and the second partition 14 divide the internal space of the oil tank body into a dirty oil tank 151, an intermediate oil tank 152 and a clean oil tank 153 in a direction from left to right.

[0045] As one specific implementation, the fuel tank body in this embodiment includes a main tank body 11 and a cover plate 12 located at the upper opening of the main tank body 11.

[0046] The first partition 13 is provided with an oil passage hole 131, and a filter element is provided at the oil passage hole 131. The cleaning oil in the dirty oil tank 151 needs to be filtered by the filter element before it can enter the intermediate oil tank 152.

[0047] A filter pipe is provided between the intermediate oil tank 152 and the clean oil tank 153, and the intermediate oil tank 152 is connected to the clean oil tank 153 through the filter pipe. A portion of the filter pipe is located outside the oil tank body, and a first oil pump 24 and a first filter 25 are provided on the filter pipe, with the first filter 25 located outside the oil tank body.

[0048] As one specific implementation method, such as Figure 2 and Figure 8 As shown, the filter pipe in this embodiment includes an oil inlet pipe 21, an oil outlet pipe 22, and a first connecting pipe 23 for connecting the oil inlet pipe 21 and the oil outlet pipe 22. Both the oil inlet pipe 21 and the oil outlet pipe 22 are located inside the oil tank, while the first connecting pipe 23 is located outside the oil tank. Figure 1 In the coordinate system shown, one end of the oil inlet pipe 21 and the oil outlet pipe 22 are both fixedly mounted on the right side plate of the oil tank body by welding. The other end of the oil inlet pipe 21 extends into the intermediate oil tank 152, and the other end of the oil outlet pipe 22 extends into the clean oil tank 153. The first oil pump 24 and the first filter 25 are both mounted on the first connecting pipe 23, and the first oil pump 24 is located upstream of the first filter 25. For example, both the oil inlet pipe 21 and the oil outlet pipe 22 include a horizontal part and a vertical part, and the horizontal part and the vertical part are smoothly transitioned.

[0049] Furthermore, the inlet end of the oil inlet pipe 21 extends to the bottom of the intermediate oil tank 152. In this way, the cleaning oil containing more impurities at the bottom of the intermediate oil tank 152 can be extracted and filtered and purified separately, thereby ensuring the cleanliness of the cleaning oil in the intermediate oil tank 152 and avoiding large fluctuations in the cleanliness of the cleaning oil in the intermediate oil tank 152.

[0050] Furthermore, the outlet end of the oil outlet pipe 22 extends to the bottom of the clean oil tank 153. This reduces the disturbance to the cleaning oil in the clean oil tank 153 when the cleaning oil flows back to the clean oil tank 153.

[0051] The first oil pump 24 draws cleaning oil from the intermediate oil tank 152, filters it through the first filter 25, and then returns it to the clean oil tank 153. Since the first filter 25 is located outside the oil tank, it can be easily disassembled and cleaned.

[0052] Preferably, the first filter 25 is a bag filter with strong dirt-holding capacity and long replacement cycle, in order to reduce operating costs. The bag filter is existing technology and can be obtained through external purchase; its internal structure will not be described in detail here.

[0053] Furthermore, a first overflow port 141 is provided on the upper end of the second partition 14.

[0054] Furthermore, the filtration component includes a first adsorption device and a filter element 32. The first adsorption device is located inside the dirty oil tank 151, directly opposite the oil passage 131, and located on the inlet side of the oil passage 131. The filter element 32 is located inside the intermediate oil tank 152, directly opposite the oil passage 131, and located on the outlet side of the oil passage 131. Preferably, the filter element 32 is a mesh filter element 32. The cleaning oil in the dirty oil tank 151 needs to pass through the first adsorption device, the oil passage 131, and the filter element 32 in sequence before entering the intermediate oil tank 152.

[0055] As one specific implementation method, such as Figure 3 As shown, the filter element 32 in this embodiment includes two frame clamps 321, and a filter screen 322 is disposed between the two frame clamps 321. The two frame clamps 321 are locked and fixed by a bolt assembly, and the filter screen 322 is clamped and fixed between the two frame clamps 321 under the locking action of the bolt assembly.

[0056] Furthermore, such as Figure 3 As shown, the oil tank body has insertion slots 163 with open tops on both sides of the filter element 32, and the two ends of the filter element 32 (according to...) Figure 1 The coordinate system shown represents the front and rear ends of the filter element 32, which are respectively inserted into the insertion slot 163.

[0057] Therefore, when it is necessary to replace or clean the filter element 32, simply pull the filter element 32 upwards to remove it.

[0058] In one specific embodiment, the first partition 13 in this embodiment is provided with curved plates 161 extending perpendicularly to the first partition 13 toward the intermediate oil tank 152 on both sides of the oil passage 131. Each curved plate 161 includes a first connecting portion, one end of which is fixedly connected to the first partition 13, and the other end of which is perpendicular to the first partition 13 and extends inward (with the opposite side of the two curved plates 161 as the inner side) to the first connecting portion. A vertical plate 162 is provided on the inner side of the first connecting portion (with the opposite side of the two curved plates 161 as the inner side) of the second connecting portion near the first partition 13. The area between the vertical plate 162 and the second connecting portion of the curved plate 161 is the insertion groove 163.

[0059] Furthermore, such as Figure 4 and Figure 5 As shown, a mounting bracket 311 is provided above the first adsorption device. A pull rod 312 is provided on the mounting bracket 311. The upper end of the pull rod 312 is detachably fixedly connected to the mounting bracket 311, and the lower end of the pull rod 312 is detachably fixedly connected to the first adsorption device. The cover plate 12 is provided with a clearance hole that allows the first adsorption device to pass through. The first adsorption device extends downward through the clearance hole into the interior of the oil tank body, and the mounting bracket 311 blocks the clearance hole.

[0060] When the first adsorption device extends into the oil tank and reaches the preset position, the mounting bracket 311 can be detachably and fixedly connected to the tank body, or the edge of the mounting bracket 311 can be directly overlapped and pressed against the edge of the clearance hole.

[0061] In one specific embodiment, the edge of the mounting bracket 311 is overlapped and pressed against the edge of the clearance hole.

[0062] In one specific embodiment, the first adsorption device in this embodiment includes two vertical plates 313. A plurality of magnetic rods 314 are evenly distributed vertically between the two vertical plates 313. The two ends of each magnetic rod 314 extend through the vertical plates 313 to the outer side of the plates 313 (with the opposite side of the two vertical plates 313 as the inner side). The vertical plates 313 have through holes for accommodating the magnetic rods. The magnetic rods 314 are strongly magnetic and capable of adsorbing iron impurities in the cleaning oil. The upper end of each vertical plate 313 is provided with a horizontally extending bent portion 3131. For example, the bent portion 3131 extends horizontally outward (with the opposite side of the two vertical plates 313 as the inner side). Two pull rods 312 are provided between the first adsorption device and the mounting frame 311. The lower end of one pull rod 312 is fixedly connected to the bent part 3131 of one side plate 313 by a locking nut 315, and the lower end of the other pull rod 312 is fixedly connected to the bent part 3131 of the other side plate 313 by a locking nut 315.

[0063] Furthermore, a first handle 3111 is provided on the upper side of the mounting bracket 311.

[0064] The purpose of this design is to allow the first adsorption device to be easily removed from the housing, thereby cleaning the iron impurities adsorbed on its upper part.

[0065] Furthermore, the lower edge of the oil passage 131 is at a distance from the bottom surface of the fuel tank. Preferably, the oil passage 131 is located in the upper middle part of the first partition 13, and the distance between the lower edge of the oil passage 131 and the bottom surface of the fuel tank is 1 / 3 of the height of the first partition 13.

[0066] The reason for this design is that the cleaning oil in the dirty oil tank 151 contains many impurities and has a lot of sediment at the bottom. Since the cleaning machine has a large flow rate, when the cleaning oil flows back into the dirty oil tank 151, it impacts and disturbs the impurities at the bottom of the dirty oil tank 151, making the cleaning oil even more turbid. The lower edge of the oil passage 131 is positioned a certain distance from the bottom surface of the oil tank to block the impurities stirred up at the bottom of the dirty oil tank 151, preventing excessive impurities from entering the intermediate oil tank 152 before the filter element can filter and purify them.

[0067] Furthermore, the intermediate oil tank 152 is equipped with several second adsorption devices 4.

[0068] In one specific embodiment, the second adsorption device 4 described in this example uses a magnetic filter, and the magnetic filter is detachably fixed to the bottom surface of the oil tank. The magnetic filter is existing technology and can be obtained externally; therefore, its internal structure will not be described in detail here. In another specific embodiment, two second adsorption devices 4 are provided inside the intermediate oil tank 152, and one of the second adsorption devices 4 is located on the side of the filter element 32 facing away from the first partition 13.

[0069] Furthermore, a second overflow port 132 is provided at the upper end of the first partition 13. When the filter component becomes clogged, causing the oil level in the dirty oil tank to be too high, the relatively clean oil in the upper part can enter the intermediate oil tank 152 through the second overflow port 132.

[0070] Furthermore, a second oil pump 53 and a second filter 54 are provided on the oil supply line connecting the oil tank and the cleaning component 9 of the cleaning machine. The inlet end of the oil supply line extends through the side wall of the oil tank and into the clean oil tank 153.

[0071] In one specific embodiment, the oil supply pipeline in this example includes an oil extraction pipe 51 and a second connecting pipe 52. The oil extraction pipe 51 is located inside the oil tank, and the second connecting pipe 52 is located outside the oil tank. Figure 1 In the coordinate system shown, one end of each oil extraction pipe 51 is fixedly mounted to the right side plate of the oil tank body by welding, and the other end of each oil extraction pipe 51 extends into the clean oil tank 153. The second oil pump 53 and the second filter 54 are both mounted on the second connecting pipe 52, with the second oil pump 53 located upstream of the second filter 54.

[0072] Preferably, the second filter 54 is a bag filter with strong dirt-holding capacity and long replacement cycle, in order to reduce operating costs. The bag filter is existing technology and can be obtained through external purchase; its internal structure will not be described in detail here.

[0073] Furthermore, a heater 6 is provided in each of the dirty oil tank 151, intermediate oil tank 152 and clean oil tank 153, and a temperature sensor 7 is provided in the clean oil tank 153 for detecting the temperature of the cleaning oil in the clean oil tank 153.

[0074] In this way, the temperature feedback from the temperature sensor 7 can be used to control the opening and operating power of the heaters 6 in the dirty oil tank 151, intermediate oil tank 152 and clean oil tank 153, thereby keeping the temperature of the cleaning oil supplied to the cleaning components 9 of the cleaning machine at 40°C, thus ensuring the best effect of the oil film.

[0075] In one specific embodiment, the dirty oil tank 151 is equipped with two heaters 6, the intermediate oil tank 152 is equipped with three heaters 6, and the clean oil tank 153 is equipped with one heater 6. The heaters 6 and the temperature sensor 7 are both located on the rear side plate of the oil tank body and extend through the rear side plate into the interior of the oil tank body.

[0076] Furthermore, the oil tank body is respectively equipped with a first liquid level sensor 81 for detecting the liquid level in the dirty oil tank 151 and a second liquid level sensor 82 for detecting the liquid level in the clean oil tank 153, so as to ensure the flow rate matching in the oil tank body.

[0077] In one specific embodiment, the first liquid level sensor 81 and the second liquid level sensor 82 described in this embodiment are both disposed on the top surface of the oil tank.

[0078] Furthermore, the bottom of the fuel tank is provided with casters 18, and the front side of the fuel tank is provided with a second handle 17 to facilitate pulling out the entire fuel tank for cleaning.

[0079] Other embodiments obtained by those skilled in the art based on the embodiments provided in this application by combining, splitting, or reorganizing the embodiments of this application do not exceed the protection scope of this application.

[0080] The above detailed embodiments have provided a detailed explanation of the purpose, technical solutions, and beneficial effects of the embodiments of this application. The above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
