Description

Technical Field

[0001] This utility model belongs to the technical field of quenching oil filtration equipment, specifically relating to a quenching oil filtration device for a heat treatment furnace. Background Technology

[0002] Heat treatment is a metal hot working process that involves heating, holding, and cooling materials in a solid state to obtain the desired microstructure and properties. Quenching oil is a commonly used process oil in heat treatment, mainly used as a quenching medium, and is particularly suitable for the quenching process of alloy steel and small-section carbon steel.

[0003] Using quenching oil can not only achieve satisfactory hardening and hardenability, but also effectively prevent cracking and reduce deformation. However, long-term use of quenching oil can lead to the formation of carbon black and oxide scale. These substances act as adsorbents, adsorbing the additives in the quenching oil, thereby accelerating the deterioration of the quenching oil's performance. Therefore, regularly removing carbon black and oxide scale is crucial for the maintenance of quenching oil.

[0004] However, existing quenching oil filtration devices have the following shortcomings in use: First, the filter membrane and filter element are fixedly installed, and when replacing the filter membrane and filter element, they are often replaced as a whole. This not only makes the disassembly and replacement process inconvenient, but also makes it impossible to replace the more consumable parts according to the actual usage. Therefore, we propose a heat treatment furnace quenching oil filtration device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment furnace quenching oil filtration device to solve the problems existing in the background art.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A quenching oil filtration device for a heat treatment furnace includes a quenching tank, with support rods fixed at the four corners of the lower end of the quenching tank. A cooling tank is fixed at the lower end of each support rod. A circulating pump is placed behind the cooling tank. An inlet pipe connects the circulating pump to the cooling tank, and an outlet pipe connects the circulating pump to the quenching tank. An mounting plate is fixed at the upper end of the cooling tank. Drop pipes are connected to the lower end of the quenching tank and the upper end of the mounting plate, and the two drop pipes are located on the same central axis. A filter disc is provided between the two drop pipes. A support plate is provided between the filter disc and the cooling tank. A replacement component is provided inside the filter disc.

[0008] The replacement component includes a mounting plate, the filter plate has a cavity inside, the mounting plate is rotatably and sealed inside the cavity, the upper end of the mounting plate has a plurality of mounting holes, each mounting hole has a filter element installed inside, and any mounting hole is on the same central axis as the discharge pipe, the upper front side of the filter plate has a fan-shaped groove communicating with the cavity, and the upper side of the filter plate has a switch assembly inside.

[0009] Further specifying, the switch assembly includes a baffle plate, an annular groove is provided on the upper side of the filter disc, the baffle plate is rotatably sealed inside the annular groove, a through groove is provided on one side of the baffle plate, and a locking assembly is provided between the baffle plate and the filter disc.

[0010] Further specifying, the locking assembly includes a handle, which is rotatably mounted on the upper end of the cover plate. The upper end of the handle has a socket, and the socket contains a pin. The upper end of the filter disc has a slot that matches the pin.

[0011] Furthermore, the filter disc has an arc-shaped groove on its outer side that communicates with the cavity, and the filter disc has a number of evenly distributed locking blocks on its outer side.

[0012] Furthermore, the outer front end of the filter disc is provided with an H-shaped elastic clip, and any of the clips can engage with the H-shaped elastic clip.

[0013] The beneficial effects of this utility model are:

[0014] 1. The device filters quenching oil through the filter element inside the filter disc, effectively removing impurities from the oil and ensuring the quality and stability of the quenching oil. By rotating the mounting disc, any filter element can be easily rotated to the inlet of the feed pipe for filtration. When the filter element needs to be replaced, simply rotate the mounting disc again and rotate the used filter element to the fan-shaped groove for direct removal and replacement. There is no need to disassemble the entire filtration device, which greatly saves replacement time and cost.

[0015] 2. Operators can easily operate the switching components and replace the filter cartridge by simply pulling out the pin and grasping the handle to rotate the baffle. Meanwhile, the arc-shaped groove and locking block design makes rotating the installation disc easier, while the H-shaped elastic locking strip prevents the installation disc from rotating when not needed, ensuring the stability of the filtration process.

[0016] 3. The device adopts a modular design, with tight connections between various components that are easy to disassemble, facilitating maintenance and upgrades by staff. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figures 1-5As shown, a quenching oil filtration device for a heat treatment furnace includes a quenching tank 100, with support rods 101 fixed at the four corners of the lower end of the quenching tank 100. A cooling tank 102 is fixed at the lower end of each support rod 101. A circulation pump 103 is placed behind the cooling tank 102. An inlet pipe 104 connects the circulation pump 103 to the cooling tank 102, and an outlet pipe 105 connects the circulation pump 103 to the quenching tank 100. An mounting plate 106 is fixed at the upper end of the cooling tank 102. A discharge pipe 107 connects to both the lower end of the quenching tank 100 and the upper end of the mounting plate 106. The two discharge pipes 107 are located on the same central axis. A filter plate 109 is provided between the two discharge pipes 107. A support plate 108 is provided between the filter plate 109 and the cooling tank 102. A replacement component is provided inside the filter plate 109.

[0028] The replacement component includes a mounting plate 200, a filter plate 109 with a cavity 201 inside, the mounting plate 200 being rotatably sealed inside the cavity 201, a number of mounting holes 202 being provided at the upper end of the mounting plate 200, a filter element 203 being installed inside each mounting hole 202, and any mounting hole 202 being on the same central axis as the discharge pipe 107, a fan-shaped groove 204 communicating with the cavity 201 being provided on the front side of the upper end of the filter plate 109, and a switch assembly being provided on the upper side inside the filter plate 109.

[0029] The quenching tank 100 can be filled with quenching oil; the support rod 101 can support the quenching tank 100; the cooling tank 102 can store the processed quenching oil; the circulating pump 103 can provide power for the flow of quenching oil; both the inlet pipe 104 and the outlet pipe 105 can transport quenching oil; the discharge pipe 107 can facilitate the direct entry of quenching oil into the cooling tank 102; the filter plate 109 can filter the quenching oil, thereby filtering out impurities in the quenching oil;

[0030] The installation hole 202 can be used to install filter element 203. By rotating the installation plate 200, any filter element 203 can be rotated to the opening of the discharge pipe 107. When the used filter element 203 is rotated to the fan-shaped groove 204, the staff can directly remove the filter element 203. This not only makes it easier to replace the filter element 203, but also does not affect the filtration of quenching oil.

[0031] When the feed pipe 107 and the filter element 203 are located on the same vertical axis, the filter element 203 can filter the flowing quenching oil.

[0032] The switch assembly can control the opening or closing of the sector groove 204. When the sector groove 204 is open, it is easier for the staff to replace the filter element 203. At the same time, the material discharge pipe 107 will be closed to prevent the quenching oil from flowing.

[0033] Initially: The switching assembly keeps the discharge pipe 107 in the closed state to prevent quenching oil from flowing out of the upper discharge pipe 107;

[0034] After the switch assembly is started: the discharge pipe 107 will be opened, and the quenching oil will enter the cooling tank 102 from top to bottom through the upper discharge pipe 107, the filter element 203 and the lower discharge pipe 107.

[0035] When replacing filter element 203: Restart the switch assembly to open the sector groove 204 and close the discharge pipe 107. Then, after rotating the mounting plate 200, the filter element 203 that needs to be replaced can be replaced through the mounting hole 202.

[0036] In this embodiment, the material discharge pipe 107 is closed by the switch assembly to prevent the quenching oil from flowing out. At the same time, the rotating mounting plate 200 drives the various mounting holes 202 and filter elements 203 to rotate, thereby facilitating the replacement of the filter elements 203 by the staff from inside the fan-shaped groove 204. This replacement method is not only convenient and quick, but also allows for targeted replacement, saving costs.

[0037] Example 2:

[0038] like Figures 1-5 As shown, based on Embodiment 1, other components of a heat treatment furnace quenching oil filtration device are further described. The switching assembly includes a baffle plate 300, an annular groove 301 is provided on the upper side of the filter disc 109, the baffle plate 300 is rotatably sealed inside the annular groove 301, a through groove 302 is provided on one side of the baffle plate 300, and a locking assembly is provided between the baffle plate 300 and the filter disc 109.

[0039] The locking assembly includes a handle 303, which is rotatably mounted on the upper end of the baffle plate 300. The upper end of the handle 303 has a socket 304, and the socket 304 has a pin 305 inside. The upper end of the filter disc 109 has a slot 306 that matches the pin 305.

[0040] An arc-shaped groove 307 communicating with the cavity 201 is provided on the outer side of the filter disc 109, and several evenly distributed locking blocks 308 are provided on the outer side of the filter disc 109.

[0041] The filter disc 109 has an H-shaped elastic clip 309 at its outer front end, and any clip 308 can engage with the H-shaped elastic clip 309.

[0042] In this embodiment, the operator can release the lock between the baffle plate 300 and the filter plate 109 by pulling out the pin 305, so that the baffle plate 300 can be rotated by grabbing the handle 303.

[0043] Since there is a through groove 302 on one side of the baffle plate 300, when the area of ​​the through groove 302 moves to the opening of the discharge pipe 107, the discharge pipe 107 will be in an open state to allow the quenching oil to flow down. At this time, the filter element 203 can filter the quenching oil. When the area of ​​the through groove 302 moves out of the opening of the discharge pipe 107, the baffle plate 300 will block the opening of the upper discharge pipe 107, thereby closing the discharge pipe 107 and preventing the quenching oil from flowing down.

[0044] The pin 305 can be inserted into the socket 304 and the slot 306 to lock the baffle 300 and the filter plate 109, thus preventing the baffle 300 from rotating and affecting the flow of quenching oil.

[0045] The arc-shaped groove 307 facilitates the exposure of each locking block 308, allowing the operator to rotate the mounting plate 200 through each locking block 308, thereby replacing the filter element 203 aligned with the inlet of the discharge pipe 107.

[0046] The H-shaped elastic retaining strip 309 can hold the retaining block 308 in place, thus preventing the mounting plate 200 from rotating and affecting the filtration of the quenching oil.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
