[0002] In equipment such as extruder temperature control systems, cooling water is commonly used to cool the equipment. However, impurities or scale in the cooling water can easily cause frequent blockages in the heating elements of the temperature control system. This is especially problematic for compact temperature control devices, where cleaning requires shutdown and disassembly, taking up to several hours and severely impacting production efficiency, while also posing a risk of burns from high temperatures. Furthermore, ordinary pipeline filters have limited filtration effectiveness and cannot meet the high water quality requirements of some applications, while professional water purification equipment is expensive, complex to install, and has a low water recovery rate, making it unsuitable for decentralized equipment layouts.

[0003] On the other hand, in equipment such as gearboxes or hydraulic stations, lubricating oil or hydraulic oil is easily contaminated and deteriorated due to high temperature and harsh working conditions. Traditional oil changing methods are difficult to operate, labor-intensive, and costly, and lack effective online filtration and cooling methods, which leads to increased equipment wear and shortened oil life.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] According to an embodiment of the present invention, a filtration device is provided, comprising: a filter housing 4, the filter housing 4 being internally divided into a water filtration chamber and an oil filtration chamber; the water filtration chamber being provided with at least one water filtration layer 7, and the water filtration chamber being connected to an inlet 5 and an outlet 9; the oil filtration chamber being provided with an oil filtration device 10, the oil filtration device 10 being provided with an oil inlet 14, an oil outlet 15, and an oil filter element 12; wherein the oil filtration chamber is surrounded by the water filtration chamber, so that the fluid flowing through the water filtration chamber exchanges heat with the oil filtration chamber.

[0024] By employing the above configuration, and placing the oil filter chamber inside and surrounding the water filter chamber, simultaneous filtration and heat exchange of both water and oil media are achieved within the same device. This effectively utilizes cooling water to cool the oil, extending its service life, while saving space and cost associated with external cooling equipment. The water filter layer 7 and the oil filter element 12 are independently configured to avoid cross-contamination, balancing filtration efficiency with system compactness, thus solving the technical problem of low operating efficiency in related filtration equipment.

[0025] like Figure 2 As shown, in the filtration device of this embodiment, the oil filtration device 10 is fixed inside the filter housing 4 by a positioning bracket; the positioning bracket includes a lower bracket; the oil filtration device 10 is located above the lower bracket, so that the oil filtration device 10 is spaced apart from the filter housing 4 on all sides.

[0026] The lower support of the positioning bracket supports the oil filtration device 10, ensuring full contact between the oil filtration chamber and the water filtration chamber, thus enhancing heat exchange efficiency. The spaced arrangement between the oil filtration device 10 and the filter housing 4 prevents vibration transmission and improves the operational stability of the device.

[0027] like Figure 2 As shown, in the filtration device of this embodiment, the oil filtration device 10 has a sealed outer shell 13, and the oil filtration chamber is located inside the sealed outer shell 13; the lower support includes a support plate 121 and a connecting plate 122; one end of the connecting plate 122 is connected to the bottom of the filter housing 4, and the connecting plate 122 is connected to the support plate 121; the sealed outer shell 13 is disposed on the support plate 121. In this way, the sealed outer shell 13 ensures the oil circuit is sealed, preventing oil-water mixing. The support plate 121 and the connecting plate 122 form a stable support structure, facilitating installation and maintenance.

[0028] like Figure 3 As shown, in the filtration device of this embodiment, the oil inlet 14 and the oil outlet 15 are arranged on opposite sides of the oil filtration device 10; or, the oil inlet 14 and the oil outlet 15 are arranged on the same side of the oil filtration device 10.

[0029] Specifically, having the inlet and outlet ports on opposite sides can extend the oil path and improve the filtration effect.

[0034] With the above setup, the multiple water filtration layers 7 filter the water step by step, improving the water purification effect; the multiple oil filter elements 12 can be used in parallel to adapt to different levels of oil pollution.

[0035] like Figure 1 As shown, in the filtration device of this embodiment, the oil filter element 12 includes, along the oil path direction, a coarse filter element, a medium filter element, and a fine filter element with gradually increasing filtration precision. In this way, the three-stage filter elements (coarse, medium, and fine) capture impurities of different particle sizes, extending the filter element life and improving oil cleanliness.

[0036] like Figure 1 As shown, in the filtration device of this embodiment, a plurality of positioning baffles 6 are provided on the inner wall of the water filtration chamber; the plurality of positioning baffles 6 are welded inside the filter housing 4, and the plurality of positioning baffles 6 are used to fix the water filtration layer 7.

[0037] With the above settings, the positioning baffle 6 precisely limits the water filter layer 7, preventing the filter layer from shifting or deforming due to water flow impact, and ensuring filtration uniformity.

[0038] like Figure 1As shown, in the filtration device of this embodiment, both ends of the filter housing 4 are sealed by flanges 3 and blind plates 1, and the blind plate 1 is connected to the flanges 3 by locking bolts 8; a sealing ring 2 is provided between the blind plate 1 and the flanges 3. In this way, the flanges 3, blind plates 1, locking bolts 8 and sealing ring 2 together form a detachable sealing structure, which facilitates opening the cover for cleaning or replacement of filter media, making maintenance convenient and the seal reliable.

[0039] The temperature control system of this embodiment includes the above-mentioned filter device. Each of the filter devices is connected in parallel to the pipeline of the temperature control system, and all of them can be connected on and off.

[0040] The temperature control system in this embodiment adopts a dual-device parallel setup with one device in use and one on standby, enabling uninterrupted switching and maintenance, greatly improving the continuous operation efficiency of the system, and is particularly suitable for high-availability scenarios such as extruder temperature control.

[0041] The assembly relationship and working principle of the filtration device in this embodiment are as follows: Sealing connection: The upper and lower blind plates 1, sealing rings 2 and upper and lower flanges 3 are connected together by locking bolts 8 to ensure that the filter is leak-free.
