Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quenching oil tank technology, and specifically relates to a multi-stage filtration device for quenching oil tank. Background Technology
[0002] Quenching oil baths are generally used in heat treatment processes. Workpieces are cooled by immersing them in the oil within the bath. After heat exchange between the oil and the workpiece, the oil temperature rises. To ensure the effectiveness of the heat treatment, the oil needs to be cooled. Typically, the oil is transported through oil pipes to a cooler for further cooling and then returned to the quenching oil bath for reuse.
[0003] Existing quenching oil tanks typically have only one oil outlet, with a single-point filter installed at the outlet. When this filter becomes clogged, it can easily cause slow oil flow, preventing the oil from cooling in time and affecting the heat treatment effect on the workpiece.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0005] The purpose of this invention is to provide a multi-stage filtration device for quenching oil tanks, thereby overcoming the defects in the prior art.
[0006] To achieve the above objectives, this utility model provides a multi-stage filtration device for a quenching oil tank, including an oil suction pipe, a primary filtration mechanism, a secondary filtration mechanism, and an oil outlet pipe. The oil suction pipe, primary filtration mechanism, and secondary filtration mechanism are installed inside the quenching oil tank. The oil suction pipe includes suction branch pipes, each with a primary filtration mechanism at its end. All suction branch pipes converge at the secondary filtration mechanism, which is connected to the oil outlet pipe. An oil pump is installed on the oil outlet pipe, which is also connected to an external cooler. A primary filter screen is installed at the inlet of the primary filtration mechanism, and a secondary filter screen is detachably installed at the outlet of the secondary filtration mechanism. The primary filter screen is a coarse filter screen, and the secondary filter screen is a fine filter screen. The primary and secondary filtration mechanisms form a multi-stage filtration system with both coarse and fine filters.
[0007] Preferably, in the technical solution, the primary filtration mechanism includes a primary filtration chamber and a primary filter screen. The primary filtration chamber has an intake port on its side, and a primary filter screen is fixedly installed at the intake port. The outlet of the primary filtration chamber is connected to the corresponding oil suction branch pipe.
[0008] Preferably, in the technical solution, the secondary filtration mechanism includes a secondary filtration chamber and a secondary filter screen. The secondary filtration chamber is connected to the oil suction branch pipe. An oil outlet chamber is provided inside the secondary filtration chamber and is connected to the oil outlet pipeline. A slot mechanism is provided at the inlet of the oil outlet chamber, and the secondary filter screen is pluggably connected to the slot mechanism.
[0009] Preferably, in the technical solution, the slot mechanism includes a front support plate, a rear support plate, a left limiting plate, a right limiting plate, and a slot. The front support plate and the rear support plate are provided at the oil outlet inlet, and the gap between the front support plate and the rear support plate forms a slot. The size of the slot matches the size of the secondary filter screen, and the secondary filter screen is pluggably connected to the slot. The left limiting plate and the right limiting plate are respectively provided on both sides of the front support plate and the rear support plate, and the two sides of the secondary filter screen are aligned with the ends of the left limiting plate and the right limiting plate, respectively.
[0010] Compared with the prior art, the present invention has the following beneficial effects: By incorporating multiple suction ports to improve oil intake efficiency, the primary and secondary filters form a multi-stage filtration system, reducing filter clogging and ensuring timely oil cooling without affecting the workpiece's heat treatment performance. The plug-in design of the secondary filter allows for easy removal and cleaning even if it becomes clogged. Attached Figure Description

Detailed Implementation
[0012] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0013] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0014] like Figure 1-6As shown, a multi-stage filtration device for a quenching oil tank includes an oil suction pipe 1, a primary filtration mechanism 2, a secondary filtration mechanism 3, and an oil outlet pipe 4. The oil suction pipe 1, the primary filtration mechanism 2, and the secondary filtration mechanism 3 are installed in a quenching oil tank 5. The oil suction pipe 1 includes oil suction branch pipes 10, and each oil suction branch pipe 10 is equipped with a primary filtration mechanism 2 at its end. All oil suction branch pipes 10 converge at the secondary filtration mechanism 3, which is connected to the oil outlet pipe 4. An oil pump is installed on the oil outlet pipe 4, and the oil outlet pipe 4 is connected to an external cooler. The primary filtration mechanism 2 and the secondary filtration mechanism 3 form a coarse and fine multi-stage filtration system.
[0015] The primary filtration mechanism 2 includes a primary filtration chamber 20 and a primary filter screen 21. The primary filtration chamber 20 has an intake port 22 on its side, and the primary filter screen 21 is fixedly installed at the intake port 22. The primary filter screen 21 is a coarse filter screen, and the outlet of the primary filtration chamber 20 is connected to the corresponding oil suction branch pipe 10.
[0016] The secondary filtration mechanism 3 includes a secondary filtration chamber 30 and a secondary filter screen 31. The secondary filtration chamber 30 is connected to the oil suction branch pipe 10. An oil outlet chamber 32 is provided inside the secondary filtration chamber 30, and the oil outlet chamber 32 is connected to the oil outlet pipe 4. A slot mechanism is provided at the inlet of the oil outlet chamber 32. The slot mechanism includes a front support plate 33, a rear support plate 34, a left limiting plate 35, a right limiting plate 36, and a slot 37. The front support plate 33 and the rear support plate 34 are provided at the inlet of the oil outlet chamber 32. The gap between the front support plate 33 and the rear support plate 34 forms a slot 37. The size of the slot 37 matches the size of the secondary filter 31. The secondary filter 31 is pluggably connected to the slot 37. The secondary filter 31 is a fine filter. Even if the secondary filter 31 is clogged, it can be disassembled and cleaned in time. The front support plate 33 and the rear support plate 34 are respectively provided with a left limiting plate 35 and a right limiting plate 36 on both sides. The two sides of the secondary filter 31 are aligned with the ends of the left limiting plate 35 and the right limiting plate 36, respectively.
[0017] During operation, the oil pump is turned on, drawing oil from the quenching oil tank 5 into the suction branch pipe 10 through the suction port 22. After being coarsely filtered by the primary filter screen 21 to remove large particles, the oil enters the suction branch pipe 10. From there, the oil flows into the secondary filter chamber 30, where it is finely filtered by the secondary filter screen 31 to remove small particles before entering the outlet chamber 32. The oil then flows through the outlet pipe 4 into the cooler for cooling. After cooling, the oil flows back into the quenching oil tank 5 via the return pipe for reuse. By setting multiple suction ports 22, the oil intake efficiency is improved. The primary and secondary filters 21 and 31 form a multi-stage filtration system, reducing filter clogging and ensuring timely cooling of the oil without affecting the heat treatment effect of the workpiece.
