Description

Technical Field

[0001] This utility model relates to the field of coolant filtration technology, specifically to a concentrated coolant composite filter device with a quickly replaceable filter screen. Background Technology

[0002] Coolant filtration devices are widely used in prefabricated substations, power equipment, industrial hydraulic systems, and other applications to remove particulate contaminants, moisture, and oxidation products from coolant, ensuring stable system operation.

[0003] When coolant is reused, it needs to be filtered by a filtration device. Most coolant filtration devices use a filter screen to filter particles inside the coolant. However, most filter screens have limited filtration efficiency and are not convenient for filtering both particles and metal impurities at the same time. Therefore, multiple filtrations are required, which is very inconvenient. Moreover, the filter screen inside most filtration devices is not easy to remove and replace.

[0004] There is an urgent need for a concentrated liquid-coolant composite filter device with a quickly replaceable filter screen to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a concentrated liquid coolant composite filter device with a quickly replaceable filter screen, in order to solve the problem of poor filtration effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concentrated liquid coolant composite filter device with a quickly replaceable filter screen, comprising a filter, a cooling water pipe fixedly connected to the top left side of the filter, a cooling plate installed on the outside of the cooling water pipe, a cooling fan fixedly installed at the front end of the cooling plate, a filter screen cylinder placed inside the filter, a threaded sleeve fixedly connected to the center of the bottom end of the filter screen cylinder, a threaded opening provided at the top of the filter, a drain pipe fixedly connected to the bottom end of the filter, a sealing cap screwed onto the outside of the threaded opening, an installation rod movably connected to the center of the bottom end of the sealing cap, a threaded rod fixedly connected to the bottom end of the installation rod, a limiting bracket fixedly connected to the inner wall of the filter screen cylinder, a magnetic rod placed inside the limiting bracket, a pull ring fixedly connected to the top end of the magnetic rod, and a handle fixedly connected to the top end of the sealing cap.

[0007] As a further technical solution of this utility model, the magnetic rods are provided in six groups, and the magnetic rods are distributed in a ring inside the filter cylinder.

[0008] As a further technical solution of this utility model, the sealing cover is threaded to the outside of the threaded opening, and the threaded rod is threaded to the inside of the threaded sleeve.

[0009] As a further technical solution of this utility model, the cooling plate is made of thermally conductive metal plate, and heat dissipation vents are uniformly opened inside the cooling plate.

[0010] As a further technical solution of this utility model, the cooling water supply pipe is distributed in a serpentine pattern, and the cooling water supply pipe is fixedly and continuously connected to the filter.

[0011] As a further technical solution of this utility model, a sealing ring is fixedly connected to the top of the filter cylinder, and the sealing ring is tightly fitted to the inner wall of the filter.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the concentrated liquid coolant composite filter device with quick-replaceable filter screen not only realizes the function of enhancing the filtration effect and the function of easy and quick disassembly and replacement of the filter screen, but also realizes the function of easy cooling and transportation.

[0013] (1) By setting up a filter screen, a magnetic rod, a sealing ring and a limiting bracket, the filter screen inside the filter can filter particulate impurities contained in the coolant. At the same time, the magnetic rod inside the filter screen can adsorb metal impurities mixed in the coolant. When the coolant passes through the filter screen, the filtration effect can be enhanced. When cleaning, simply hold the pull ring and remove the magnetic rod from inside the limiting bracket for cleaning. This structure realizes the function of facilitating enhanced filtration effect.

[0014] (2) By setting a sealing cover, handle, threaded opening, mounting rod, threaded rod and threaded sleeve, when replacing the filter screen, the operator holds the handle and rotates the sealing cover. When the sealing cover is removed from the filter screen, the filter screen can be directly taken out from the inside of the filter. Then, the operator holds the mounting rod and rotates it. After the threaded rod at the bottom of the mounting rod is unscrewed from the inside of the threaded sleeve, the filter screen can be disassembled and replaced. This structure realizes the function of easy and quick disassembly and replacement of the filter screen.

[0015] (3) By setting up a cooling water pipe, a cooling plate, a cooling fan and a heat dissipation port, the coolant can enter the interior of the filter through the cooling water pipe. The cooling water pipe is relatively long. During the process of the coolant passing through the cooling water pipe, the cooling plate and the cooling fan can cool the cooling water pipe to ensure that the temperature of the coolant will not be too high when it enters the filter. This structure realizes the function of convenient cooling and transportation. Attached Figure Description

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

[0022] Please see Figure 1-4 An embodiment of this utility model provides a concentrated coolant composite filter device with a quick-replaceable filter screen, comprising a filter 1, a cooling water pipe 4 fixedly connected to the top left side of the filter 1, a cooling plate 5 installed on the outside of the cooling water pipe 4, a cooling fan 6 fixedly installed at the front end of the cooling plate 5, a filter screen cylinder 2 placed inside the filter 1, a threaded sleeve 16 fixedly connected to the center of the bottom end of the filter screen cylinder 2, a threaded opening 9 provided at the top of the filter 1, a drain pipe 10 fixedly connected to the bottom end of the filter 1, a sealing cap 7 screwed onto the outside of the threaded opening 9, an installation rod 3 movably connected to the center of the bottom end of the sealing cap 7, a threaded rod 15 fixedly connected to the bottom end of the installation rod 3, a limiting bracket 14 fixedly connected to the inner wall of the filter screen cylinder 2, a magnetic rod 12 placed inside the limiting bracket 14, a pull ring 13 fixedly connected to the top end of the magnetic rod 12, and a handle 8 fixedly connected to the top end of the sealing cap 7.

[0023] There are six sets of magnetic rods 12, which are arranged in a ring inside the filter cylinder 2. A sealing ring 11 is fixedly connected to the top of the filter cylinder 2, and the sealing ring 11 is tightly attached to the inner wall of the filter 1.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the filter screen 2 inside the filter 1 can filter particulate impurities contained in the coolant. At the same time, the magnetic rod 12 inside the filter screen 2 can adsorb metallic impurities mixed in the coolant. When the coolant passes through the filter screen 2, the filtration effect can be enhanced. When cleaning, simply hold the pull ring 13 and remove the magnetic rod 12 from inside the limiting bracket 14 for cleaning.

[0025] The sealing cap 7 covers the outside of the threaded opening 9 in a threaded connection, and the threaded rod 15 is embedded inside the threaded sleeve 16 in a threaded connection.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, when replacing the filter cartridge 2, the operator holds the handle 8 and rotates the sealing cover 7. When the sealing cover 7 is removed from the filter cartridge 2, the filter cartridge 2 can be directly taken out from the inside of the filter 1. Then, the operator holds the mounting rod 3 and rotates it. After the threaded rod 15 at the bottom of the mounting rod 3 is unscrewed from the inside of the threaded sleeve 16, the filter cartridge 2 can be disassembled and replaced.

[0027] The cooling plate 5 is made of thermally conductive metal plate. The cooling plate 5 has heat dissipation vents 17 evenly distributed inside. The cooling water pipes 4 are distributed in a serpentine pattern and are fixedly connected to the filter 1.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the coolant can enter the interior of the filter 1 through the cooling water pipe 4. The cooling water pipe 4 is relatively long. During the process of the coolant passing through the cooling water pipe 4, the cooling plate 5 and the cooling fan 6 can cool the cooling water pipe 4 to ensure that the temperature of the coolant does not become too high when it enters the filter 1.

[0029] Working principle: Coolant can enter the interior of filter 1 through cooling water pipe 4. Cooling water pipe 4 is relatively long. During the process of cooling water pipe 4, cooling plate 5 and cooling fan 6 can cool the cooling water pipe 4. The filter screen 2 inside filter 1 can filter particulate impurities contained in the coolant. At the same time, the magnetic rod 12 inside the filter screen 2 can adsorb metal impurities mixed in the coolant. The filtration effect is enhanced when the coolant passes through the filter screen 2. When cleaning, hold the pull ring 13 and directly remove the magnetic rod 12 from the limit bracket 14 for cleaning. When replacing the filter screen 2, the operator holds the handle 8 and rotates the sealing cover 7. When the sealing cover 7 is removed from the filter screen 2, the filter screen 2 can be directly taken out from the interior of filter 1. Then, hold the installation rod 3 and rotate it. After the threaded rod 15 at the bottom of the installation rod 3 is unscrewed from the inside of the threaded sleeve 16, the filter screen 2 can be disassembled and replaced. The filtered coolant is discharged through drain pipe 10 to complete the filtration process.
