Description

Technical Field

[0001] This utility model belongs to the field of filtration equipment, and specifically relates to a filter that is easy to discharge sewage. Background Technology

[0002] Filters are widely used in metallurgy, power, petrochemical, environmental protection, agriculture, and water conservancy, filtering wastewater through filter cartridges installed inside. Existing filters typically lack drain outlets, allowing impurities to accumulate inside over time, causing blockages and affecting filtration efficiency. Furthermore, the filter cartridge, as a separate component, is usually bolted to the filter. However, because bolted connections are rigid, they often loosen over time, leading to filter instability and impacting filtration effectiveness. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a filter that facilitates sewage discharge, featuring a sewage outlet for convenient sewage removal.

[0004] Another objective of this invention is to provide a filter that facilitates sewage discharge and has a stable filtration structure.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides a filter that facilitates sewage discharge, comprising:

[0007] The main housing contains a filter chamber. The side wall of the main housing has an inlet and an outlet connected to the filter chamber. The filter chamber contains a filter element, and the inlet and outlet are separated by the filter element. The bottom of the main housing has a drain outlet connected to the filter chamber.

[0008] A pressing structure, the pressing structure including a pressing member, the pressing member pressing against the filter element.

[0009] Furthermore, the main housing is also provided with a pressure gauge port for installing a pressure gauge. This port allows for the installation of a pressure gauge, which can display the pressure inside the filter in real time, thus enabling staff to determine whether drainage is necessary based on the pressure readings.

[0010] Furthermore, the main housing includes a head, a tube body, and a base plate. The head is connected to the top of the tube body, and the base plate is connected to the bottom of the tube body. Both the head and the tube body are provided with manhole flanges on their edges, and the manhole flanges are detachably connected by lifting rings.

[0011] Furthermore, the lifting ring includes a mounting base, a rotating shaft, a connecting rod, a locking buckle, and a ring body. The mounting base is fixed to the side wall of the pipe body and has a shaft hole. The rotating shaft passes through the shaft hole and is rotatably connected to the mounting base. One end of the connecting rod is connected to the rotating shaft, and the other end is threadedly connected to the locking buckle. The locking buckle is fastened to the end cap, and the ring body is connected to the end of the locking buckle away from the connecting rod. Through this structural arrangement, the locking buckle can rotate threadedly on the connecting rod, achieving locking and releasing between the end cap and the pipe body.

[0012] Furthermore, the pipe body is welded to the chassis, and both the end cap and the pipe body are welded to the manhole flange.

[0013] Furthermore, the filter element includes a filter element body, a filter element fixing plate, and a filter element pressure plate. The inlet and outlet are located on opposite sides of the filter element fixing plate. The filter element fixing plate is sealed to the inner wall of the main housing. The filter element body is mounted on the filter element fixing plate, and the filter element pressure plate is mounted on the top of the filter element body. The clamping element is a spring, and the clamping structure also includes a top plate, which is fixedly connected to the inner wall of the main housing. One end of the spring abuts against or connects to the filter element pressure plate, and the other end abuts against or connects to the top plate. In this application, the filter element fixing plate can separate the inlet and outlet, thereby preventing sewage from flowing directly out of the outlet without passing through the filter element. By setting a spring as a clamping element, even if the filter element shifts in position due to prolonged use, the spring can always press the filter element pressure plate against the filter element body using an elastic soft connection, thereby preventing the filter element from loosening and improving the stability of the filtration structure.

[0014] Furthermore, the filter element body is a filter bucket with an open top, and the filter element fixing plate has a ring structure. The outer ring of the filter element fixing plate is slidably and sealingly connected to the inner wall of the main housing, while the inner ring is connected to the filter element body. The filter element fixing plate can slide relative to the main housing, allowing the filter bucket to move up and down within the main housing. A spring provides a soft connection and shock absorption effect.

[0015] Furthermore, the filter element pressure plate is provided with through holes, which allows the filter barrel to communicate with the water inlet. Wastewater enters the filter barrel from the water inlet through the through holes on the filter element pressure plate, and then enters the filter chamber after being filtered by the wall of the filter barrel, and then flows out from the water outlet.

[0016] Furthermore, a sealing ring is provided between the filter element fixing plate, the filter element pressure plate and the filter element body to prevent sewage from flowing into the outlet from the gap between the three.

[0017] Furthermore, the filter element includes a filter element body and a central water outlet rod. The filter element body has a through hole running vertically through it, and the central water outlet rod is disposed within the through hole. A mounting plate is disposed within the main housing. The water inlet is located on the upper side of the mounting plate, and the water outlets are located on the lower side of the mounting plate. The filter element body is fixed to the mounting plate, and the mounting plate has a water outlet hole. The lower end of the central water outlet rod is directly opposite the water outlet hole. The clamping component uses fastening bolts, and the clamping structure also includes a filter element fixing cover. The filter element fixing cover is fixed to the upper end of the filter element body, and the fastening bolts pass through the filter element fixing cover and are threadedly connected to the central water outlet rod. In this application, the filter element fixing cover can seal the upper end of the central water outlet rod, and the fastening bolts can press the central water outlet rod from the upper end, thereby preventing the central water outlet rod from moving and improving the stability of the filtration structure.

[0018] Furthermore, the central outlet rod has a hollow structure and a through hole communicating with the filter element body. Wastewater enters the filter chamber, is filtered by the filter element body, enters the central outlet rod, and then flows into the outlet through the outlet hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are: it is equipped with a drain outlet and a pressing structure, so that the impurities filtered out by the filter element can be discharged through the drain outlet, thereby avoiding filter clogging; in addition, the pressing structure can press the filter element tightly, thereby preventing the filter element from loosening and improving the stability of the filtration structure.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To achieve the above objectives, the technical solution of this utility model is as follows:

[0031] See Figure 1-8 As shown, this embodiment provides a filter that facilitates sewage discharge, comprising:

[0032] The main housing 1 has a filter chamber 11 inside. The side wall of the main housing 1 has an inlet 13 and an outlet 12 that are connected to the filter chamber 11. The filter chamber 11 has a filter element 2 inside. The inlet 13 and the outlet 12 are separated by the filter element 2. The bottom of the main housing 1 has a drain outlet 14 that is connected to the filter chamber 11.

[0033] The pressing structure 3 includes a pressing element 31, which presses against the filter element 2.

[0034] In this embodiment, the impurities filtered out by the filter element 2 can be discharged through the drain port 14, thereby avoiding filter clogging; in addition, the pressing structure 3 can press the filter element 2 tightly, thereby preventing the filter element 2 from loosening and improving the stability of the filtration structure.

[0035] Furthermore, the main housing 1 is also provided with a pressure gauge port 15 for installing a pressure gauge. The pressure gauge port 15 can be used to install a pressure gauge, which can display the pressure inside the filter in real time, so that the staff can easily determine whether sewage needs to be discharged based on the pressure.

[0036] Furthermore, the main housing 1 includes a head 16, a pipe body 17, and a base 18. The head 16 is connected to the top of the pipe body 17, and the base 18 is connected to the bottom of the pipe body 17. Both the head 16 and the pipe body 17 have manhole flanges 19 on their edges, and these manhole flanges 19 are detachably connected by a lifting ring 4. Compared to the traditional bolt connection method, this application uses a lifting ring 4 to connect the head 16 and the pipe body 17, which facilitates disassembly and allows for easy opening of the filter for replacement and maintenance.

[0037] Further, see Figure 8 The lifting ring 4 includes a mounting base 41, a rotating shaft 42, a connecting rod 43, a locking buckle 44, and a ring body 45. The mounting base 41 is fixed to the side wall of the pipe body and has a shaft hole 46. The rotating shaft 42 passes through the shaft hole and is rotatably connected to the mounting base 41. One end of the connecting rod 43 is connected to the rotating shaft 42, and the other end is threadedly connected to the locking buckle 44. The locking buckle 44 is fastened to the end cap, and the ring body 45 is connected to the end of the locking buckle 44 away from the connecting rod 43. Through the above structure, the locking buckle 44 can rotate threadedly on the connecting rod 43, realizing the locking and releasing between the end cap and the pipe body.

[0038] Furthermore, the pipe body 17 is welded to the chassis 18, and both the end cap 16 and the pipe body 17 are welded to the manhole flange 19.

[0039] Furthermore, the filter element 2 and the compression structure 3 of this application have multiple embodiments, specifically:

[0040] See Figure 1-4 In Embodiment 1, the filter element 2 includes a filter element body 21, a filter element fixing plate 22, and a filter element pressure plate 23. The inlet 13 and outlet 12 are located on opposite sides of the filter element fixing plate 22. The filter element fixing plate 22 is sealed to the inner wall of the main housing 1. The filter element body 21 is mounted on the filter element fixing plate 22, and the filter element pressure plate 23 is mounted on the top of the filter element body 21. The clamping member 31 is a spring, and the clamping structure 3 also includes a top plate 32, which is fixedly connected to the inner wall of the main housing 1. One end of the spring abuts against or connects to the filter element pressure plate 23, and the other end abuts against or connects to the top plate 32. In this embodiment, the filter element fixing plate 22 can separate the inlet 13 and the outlet 12, thereby preventing sewage from flowing directly out of the outlet 12 without passing through the filter element. By setting a spring as the clamping element 31, even if the filter element shifts in position due to long-term use, the spring can always press the filter element pressure plate 23 against the filter element body 21 using the elastic soft connection, thereby preventing the filter element from loosening and improving the stability of the filtration structure.

[0041] Furthermore, the filter element body 21 is a filter bucket with an open top, and the filter element fixing plate 22 has a ring structure. The outer ring of the filter element fixing plate 22 is slidably and sealingly connected to the inner wall of the main housing 1, and the inner ring is connected to the filter element body 21. The filter element fixing plate 22 can slide relative to the main housing 1, allowing the filter bucket to move up and down within the main housing 1. It is also softly connected by a spring, providing a shock absorption effect.

[0042] Furthermore, the filter element plate 23 is provided with through holes, which allows the filter barrel to communicate with the outlet 12. Wastewater enters the filter barrel from the inlet 13 through the through holes on the filter element plate 23, and then enters the filter chamber 11 after being filtered by the wall of the filter barrel, and then flows out from the outlet 12.

[0043] Furthermore, the bottom of the filter bucket is provided with a drain hole for sewage discharge. The drain hole is a through hole with several lower diameter holes, which allows the sewage that settles at the bottom of the filter bucket to enter the filter chamber 11 through the drain hole and then be discharged from the sewage outlet.

[0044] Furthermore, a sealing ring 24 is provided between the filter element fixing plate 22, the filter element pressing plate 23 and the filter element body 21 to prevent sewage from flowing into the outlet 12 through the gap between the three.

[0045] See Figure 5-7 In embodiment 2, the filter element 2 includes a filter element body 21 and a central water outlet rod 25. The filter element body 21 has a through hole running vertically through it, and the central water outlet rod 25 is disposed within the through hole. A mounting plate 5 is disposed within the main housing 1. An inlet 13 is located on the upper side of the mounting plate 5, and outlets 12 are located on the lower side of the mounting plate 5. The filter element body 21 is fixed to the mounting plate 5, which has an outlet hole 51. The lower end of the central water outlet rod 25 is directly opposite the outlet hole 51. The clamping member 31 uses fastening bolts. The clamping structure 3 also includes a filter element fixing cover 33, which is fixed to the upper end of the filter element body 21. The fastening bolts pass through the filter element fixing cover 33 and are threadedly connected to the central water outlet rod 25. In this embodiment, the filter element fixing cover 33 can seal the upper end of the central water outlet rod 25, and the fastening bolts can press the central water outlet rod 25 from the upper end, thereby preventing the central water outlet rod 25 from moving and improving the stability of the filtration structure.

[0046] Furthermore, the central outlet rod 25 has a hollow structure, and a through hole communicating with the filter element body 21 is provided on the central outlet rod 25. Wastewater enters the filter chamber 11, is filtered by the filter element body 21, enters the central outlet rod 25, and then flows into the outlet 12 through the outlet hole 51.

[0047] Furthermore, there are two drain outlets 14, located above and below the mounting plate 5 respectively, which can discharge sewage before and after filtration.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
