Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a filtration device for a mechanical drainer. Background Technology

[0002] A mechanical drain is a device that uses mechanical principles to drain water. It mainly consists of a shaft, an impeller, and a pump body. When the motor starts, the shaft drives the impeller to rotate, creating pressure and flow rate, drawing water from the pump body and then discharging it through pipes. Mechanical drains are widely used in equipment such as air conditioners, refrigerators, and washing machines to drain condensate or other liquids generated during operation. However, existing mechanical drains often lack efficient filtration devices, allowing impurities and particulate matter to easily enter the drain pipes, causing blockages or affecting drainage efficiency. Furthermore, the filtration devices are often difficult to remove and clean completely, leading to poor filtration performance after prolonged use and potential blockages that can affect the operation of the water distributor.

[0003] In the prior art, the authorized announcement number is CN215862915U. A gas drainer includes a drainer body, a base installed at the bottom of the drainer body, a level gauge installed on one side of the upper end of the drainer body and the level gauge is connected to the inside of the drainer body, a temperature controller installed on the other side of the upper end of the drainer body and the temperature controller is electrically connected to the temperature sensor inside the drainer body, and a water inlet is installed on one side of the upper end of the drainer body and a water inlet valve is installed on the water inlet.

[0004] The aforementioned patents lack efficient filtration devices, which makes it easy for impurities and particulate matter to enter the drainage pipes, causing blockages or affecting drainage efficiency. At the same time, the filtration devices are often not easy to disassemble and clean as a whole, resulting in poor filtration effect after long-term use and possible blockage of the filtration device, which may affect the operation of the water distributor. Therefore, we need to propose a filtration device for mechanical drainers. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] This utility model provides: a filtration device for a mechanical drainer, such as... Figure 1-5 As shown, the filter includes a filter bucket 1 and a lid 2 bolted to the top of the filter bucket 1. An upper connecting pipe 3 is sealed to the upper surface of the lid 2, and a lower connecting pipe 7 is sealed to the bottom of the filter bucket 1. A sealing strip 24 is fixedly installed on the lower surface of the lid 2, and a sealing groove 23 corresponding to the sealing strip 24 is opened on the upper surface of the filter bucket 1. The lid 2 is bolted to the filter bucket 1, which makes it easy to remove the filter bucket 1 as a whole for cleaning. When the lid 2 and the filter bucket 1 are connected, the sealing strip 24 on the lower surface of the lid 2 will be inserted into the sealing groove 23 on the upper surface of the filter bucket 1, thereby improving the sealing performance of the connection between the filter bucket 1 and the lid 2, and thus ensuring the stability of the water entering and leaving the filter bucket 1.

[0026] Preferably, a removable and washable filter assembly is provided inside the filter tank 1 and located on the lower surface of the tank cover 2. The filter assembly includes a fine filter cartridge 10, a medium filter cartridge 11, a coarse filter cartridge 12, a connecting module, and a limiting module. Two sets of limiting modules are provided. The coarse filter cartridge 12 is positioned on the lower surface of the tank cover 2 via the limiting modules. The medium filter cartridge 11 and the fine filter cartridge 10 are sequentially fitted onto the outer arc surface of the coarse filter cartridge 12 via the connecting modules. The fine filter cartridge 10, the medium filter cartridge 11, and the coarse filter cartridge 12 are made of stainless steel or corrosion-resistant synthetic materials. It has good durability and corrosion resistance. The coarse filter cartridge 12 is used to intercept larger particles, while the fine filter cartridge 10 and the medium filter cartridge 11 are used to intercept fine impurities. Although the medium filter cartridge 11 can slide slightly between the fine filter cartridge 10 and the coarse filter cartridge 12, the distance between the fine filter cartridge 10 and the coarse filter cartridge 12 is fixed. This ensures that a certain amount of particles and impurities can exist between the fine filter cartridge 10, the medium filter cartridge 11 and the coarse filter cartridge 12, thereby achieving efficient filtration of the drain and preventing impurities from clogging the drain.

[0027] Furthermore, the connecting module includes a limiting block 14, an extension plate 17, and a spring plunger 18. Two sets of each of the limiting block 14, extension plate 17, and spring plunger 18 are provided. Two sets of extension plates 17 are symmetrically arranged on the upper surface of the coarse filter cartridge 12, and two sets of spring plungers 18 are fixedly arranged on the lower surface of the corresponding extension plates 17. Both sets of limiting blocks 14 are located below the corresponding spring plungers 18. The limiting block 14 is a convex block, and the outer arc surfaces of the fine filter cartridge 10, the middle filter cartridge 11, and the coarse filter cartridge 12 are all provided with limiting grooves 19 corresponding to the limiting block 14. The upper surfaces of both sets of limiting blocks 14 are provided with positioning holes 16 corresponding to the spring plungers 18. The corresponding surfaces of both sets of limiting blocks 14 are... An operating rod 15 is fixedly connected. The limiting block 14 passes sequentially through the limiting groove 19 on the side of the coarse filter cylinder 12, the middle filter cylinder 11, and the fine filter cylinder 10 from inside the coarse filter cylinder 12. The limiting groove 19 on the inside of the fine filter cylinder 10 does not penetrate the fine filter cylinder 10. Therefore, when the limiting block 14 is inserted into the bottom of the limiting groove 19 on the inside of the fine filter cylinder 10, the limiting block 14 will be unable to move further. Then, the spring plunger 18 on the lower surface of the extension plate 17 is inserted into the positioning hole 16 on the upper surface of the limiting block 14, thereby limiting the limiting block 14. The fine filter cylinder 10, the middle filter cylinder 11, and the coarse filter cylinder 12 are connected by the limiting block 14. The limiting block 14 is a protrusion to ensure the stability of the connection.

[0028] Furthermore, the limiting module includes limiting posts 13, threaded rods 20, limiting rings 21, and support plates 22. Two sets of limiting posts 13 are symmetrically arranged on the upper surface of the coarse filter cylinder 12, and two sets of limiting rings 21 are respectively fixedly arranged on the upper surface of the corresponding limiting posts 13. Both sets of limiting posts 13 penetrate the upper surface of the lid 2. The support plate 22 is fixedly arranged on the upper surface of the lid 2. The threaded rod 20 is threaded through the corresponding support plate 22. The support plate 22 is set in several groups, so that the threaded rod 20 is supported by several sets of support plates 22 to ensure the stability of the threaded rod 20 during rotation. The threaded rod 20 penetrates the corresponding limiting ring 21. The limiting posts 13 on the upper surface of the coarse filter cylinder 12 slide through the lid 2, and then the threaded rod 20 is rotated to move. The threaded rod 20 enters the center of the corresponding limiting ring 21, thereby limiting the limiting ring 21 and thus locking the coarse filter cylinder 12 onto the lower surface of the lid 2.

[0029] Specifically, the upper surface of the upper connecting pipe 3 is connected to the inlet pipe 4 via two sets of upper flanges 6, and the upper surface of the inlet pipe 4 is sealed with a stop valve 5; the lower surface of the lower connecting pipe 7 is sealed with a set of lower flanges 8, and the lower surface of the lower flanges 8 is connected to the outlet pipe 9 via another set of lower flanges 8. The start and stop of the water inlet is controlled by the stop valve 5, and the water inlet is sealed with the stop valve 5. Then, the water enters the filter tank 1 through the inlet pipe 4 and the upper connecting pipe 3. The filtered water enters the drainer through the lower connecting pipe 7 and the outlet pipe 9, thereby efficiently filtering the drainer and preventing impurities from clogging it.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
