Description

Technical Field

[0001] The utility model belongs to the technical field of water pitcher filtering, and in particular relates to an intercepting filtering device. Background Art

[0002] Water tanks are widely used in industry. They are mainly made of stainless steel and are processed through multiple processes to obtain a cylindrical tank body. Depending on the purpose of the water tank, its volume often varies greatly. For example, the tank body for industrial water storage is mostly a large tank body to meet the water needs of production and processing.

[0003] When pumping water into the water tank for storage, it is necessary to install a filtering device on the top of the water tank. The most common method is physical filtration, which is to install a filter to intercept dirt and other substances in the water, thereby avoiding serious pollution of the water tank and blockage of the pipe system on the water tank.

[0004] During operation, especially when there is a large amount of dirt in the water, the filter structure on the water tank can be easily and quickly clogged by solids and other substances, which can reduce its filtering speed. Therefore, in actual use, the filter structure needs to be disassembled and cleaned regularly.

[0005] However, in actual use, the purpose of the water tank is different, and the water quality stored in it is often different. For example, in the use of a water tank with a large amount of scale precipitation, a large amount of scale solids precipitated can easily quickly block the filter holes on the filter structure and adhere to the filter hole structure and cannot be separated, resulting in an extremely slow filtration speed. At the same time, the frequency of disassembly and cleaning is greatly increased.

[0006] As a result, in actual use, the solid matter attached to and blocked on the filter structure cannot be detached, resulting in a slow water flow rate, seriously affecting the normal use of the water tank. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide an intercepting and filtering device.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] An interception and filtering device comprises an external fixed mounting ring seat, an internal flip seat is rotatably connected inside the external fixed mounting ring seat, and a plurality of filter bag filtering mechanisms are assembled and connected on the internal flip seat;

[0010] The interception and filtering device also includes a pushing mechanism for pushing the inner flip seat to flip, the pushing mechanism includes a support fixedly connected to the top edge of the inner flip seat, the pushing mechanism also includes a pushing cylinder, the piston rod of the pushing cylinder is fixedly connected to a push rod, the bottom of the push rod is fixedly connected to a push ring, the support is fixedly connected to a connecting pin, and the push ring is sleeved on the connecting pin;

[0011] After a long period of filtration, the filtered impurities attached to the filter mechanism of the filter bag cannot fall off and are attached to the filter hole structure. The pushing mechanism pushes the inner flip seat to flip and swing, and the blocked impurities attached to the filter hole structure are shaken off.

[0012] Preferably, both ends of the inner flip seat are respectively fixedly connected with pins rotatably connected to the outer fixed mounting ring seat;

[0013] The inner flip seat abuts against the inner side wall of the outer fixed mounting ring seat.

[0014] Preferably, the filter bag filtering mechanism comprises a plurality of filter bags, the filter bag comprises a filter bag body, a sealed storage bag is integrally formed at the bottom of the filter bag body, and the storage bag is in a curved shape.

[0015] Preferably, a rectangular sleeve is integrally formed on the top of the filter bag body, a rectangular mounting through hole is opened on the inner flip seat, the rectangular sleeve is lined in the rectangular mounting through hole, and the rectangular sleeve is fastened to the rectangular mounting through hole by a connecting screw.

[0016] Preferably, an annular mounting flange is welded on the outer side wall of the outer fixed mounting ring seat, and the annular mounting flange is fixedly mounted on the inner side wall of the water tank.

[0017] Preferably, an annular groove is provided on the outer side wall of the annular mounting flange, and a sealing gasket is clamped in the annular groove.

[0018] Preferably, a plurality of spring return mechanisms cooperating with the pushing mechanism are fixedly connected to the inner flip seat;

[0019] When the inner turning seat is turned over, it is reset by the spring reset mechanism.

[0020] Preferably, the spring return mechanism comprises spring seat plates respectively fixedly connected to the top of the inner flip seat and the outer fixed mounting ring seat, and a connecting spring is fixedly connected between the spring seat plates;

[0021] When the inner flip seat flips, the connecting spring is lifted up and bent to pull, and then flips and resets under the elastic restoring force of the connecting spring.

[0022] Preferably, a cylinder barrel of the push cylinder is fixedly connected to a cylinder barrel mounting seat, and a plurality of long connecting screws are fixedly assembled and connected to the cylinder barrel mounting seat, and the long connecting screws are fastened to the top of the external fixed mounting ring seat.

[0023] The utility model has the following beneficial effects:

[0024] 1. To shake off the dirt on the filter hole, the push rod-push ring is pushed by the push cylinder to press against the connecting pin. At this time, the inner flip seat is flipped at an appropriate angle (the flip angle is determined by the gap between the push ring and the connecting pin) under the contact pressure. During the flipping process, the filter bag filter mechanism keeps swinging. During the swinging process, a large amount of materials attached to and blocked on the filter holes of the filter bag filter mechanism are continuously detached, thereby releasing the filter hole structure, thereby improving the filtering effect and the water flow rate. This method intervenes in the filter bag filter mechanism in a simple and effective way to ensure that it maintains high-efficiency filtering.

[0025] 2. A sealed storage capsule is formed integrally at the bottom of the filter bag body. The storage capsule is curved in shape. The purpose of forming the storage capsule integrally at the bottom of the filter bag body is to store the impurities that are shaken off.

[0026] Through the filter bag design, during the flipping process of the inner flip seat, the soft filter bag body (the filter bag body is loaded with filtered impurities, and the filtered impurities are loaded on the filter holes) has a certain weight and will follow the violent swing. During the swinging process, the impurities loaded on the filter holes, such as water alkali, are quickly detached, thereby realizing a large-area release of the filter hole structure.

[0037] Example 1

[0038] like Figure 1-5 As shown, an interception and filtering device includes an external fixed mounting ring seat 1, an annular mounting flange 3 (which abuts against the inner wall of the water tank mouth to form a seal) is welded on the outer wall of the external fixed mounting ring seat 1, and the annular mounting flange 3 is fixedly mounted on the inner wall of the water tank. Specifically, according to the existing method, a connecting plate is welded on the annular mounting flange 3, and the fastening installation is achieved by the connecting screws on the connecting plate.

[0039] At the same time, in order to improve the sealing, according to the existing sealing ring sealing method, an annular groove 32 is opened on the outer side wall of the annular mounting flange 3, and a sealing gasket 31 is clamped in the annular groove 32.

[0040] The outer fixed mounting ring seat 1 is rotatably connected with an inner flip seat 2, and a plurality of filter bag filtering mechanisms are assembled and connected on the inner flip seat 2. During operation, water is filtered from each filter bag filtering mechanism.

[0041] The inner flip seat 2 rotates in the following manner:

[0042] Pins rotatably connected to the outer fixed mounting ring seat 1 are welded on the left and right side walls of the inner flip seat 2 (a matching pin through hole is provided on the outer fixed mounting ring seat 1); in a horizontal state, the inner flip seat 2 contacts the inner side wall of the outer fixed mounting ring seat 1 and maintains a certain sealing performance.

[0043] In actual operation, a gasket can be installed on the inner wall of the outer fixed mounting ring seat 1 (staggered at the location of the pin), and when the inner flip seat 2 is in a horizontal state, the gasket contacts the matching ring groove of the inner flip seat 2 to maintain sealing.

[0044] At the same time, the intercepting and filtering device also includes a pushing mechanism 5 for pushing the inner flip seat 2 to flip (the pushing mechanism 5 is located at the top front side of the inner flip seat 2), the pushing mechanism 5 includes a support 53 fixedly connected to the top edge of the inner flip seat 2 (fixed at the top front side of the inner flip seat 2), the pushing mechanism 5 also includes a pushing cylinder 51, the piston rod of the pushing cylinder 51 is fixedly connected to a push rod 54, the bottom of the push rod 54 is fixedly connected to a push ring 541, the support 53 is fixedly connected to a connecting pin, and the push ring 541 is sleeved on the connecting pin.

[0045] Specifically, since the center of the push ring 541 is larger than the connecting pin, a large space is reserved after the push ring 541 is sleeved on the connecting pin. When the push cylinder 51 pushes, the push rod 54-push ring 541 touches the connecting pin. At this time, under the contact pressure, the inner flip seat 2 flips at an appropriate angle (the flip angle is determined by the gap between the push ring 541 and the connecting pin). During the flipping process, the filter bag filter mechanism continuously swings. During the swinging process, a large amount of material attached to and blocked on the filter hole of the filter bag filter mechanism is continuously detached, thereby releasing the filter hole structure, thereby improving the filtering effect and the water flow rate. In addition, this method intervenes in the filter bag filter mechanism in a simple and effective way to ensure that it maintains high-efficiency filtering.

[0046] Example 2

[0047] like Figure 1-5As shown, based on the structure of Example 1, the filter bag filtering mechanism of this embodiment includes a plurality of filter bags 4, wherein the filter bag 4 includes a filter bag body (the filter bag 4 body is a filter bag 4 with a filter hole structure made of materials such as nylon), and a sealed storage capsule 42 is integrally formed at the bottom of the filter bag body (it is made of elastic rubber material with high elasticity. During filtering, water is filtered from the filter holes on the filter bag body, and only a small amount of water is retained in the storage capsule 42), and the storage capsule 42 is curved (the storage capsule 42 is integrally formed at the bottom of the filter bag 4 body to store impurities that are shaken off).

[0048] At the same time, a rectangular sleeve 41 (made of plastic) is integrally formed on the top of the filter bag 4 body, and a rectangular mounting hole 21 is opened on the inner flip seat 2. The rectangular sleeve 41 is lined in the rectangular mounting hole, and the rectangular sleeve 41 is fastened to the rectangular mounting hole 21 by a connecting screw.

[0049] Through the above-mentioned structural design, during the flipping process of the inner flip seat 2, the filter bag 4 body with a soft texture (the filter bag 4 body is loaded with filtered impurities, and the filtered impurities are loaded on the filter holes) has a certain weight and follows the swing. During the swinging process, the impurities loaded on the filter holes, such as water alkali, are quickly separated, thereby realizing a large-area release of the filter hole structure.

[0050] Example 3

[0051] like Figure 1-5 As shown, based on the structure of Example 1, this embodiment has a plurality of spring reset mechanisms fixedly connected to the inner flip seat 2 and cooperating with the pushing mechanism 5; the spring reset mechanism is used to reset the inner flip seat 2 after it is flipped.

[0052] Specifically, the spring return mechanism is arranged at the rear side of the top of the inner flip seat 2 (the connecting line between the pins of the inner flip seat 2 is taken as the dividing line, and is located at the rear side of the dividing line).

[0053] Preferably, the spring return mechanism comprises spring seat plates 61 respectively fixedly connected to the top of the inner flip seat 2 and the outer fixed mounting ring seat 1, and a connecting spring 62 is fixedly connected between the spring seat plates 61;

[0054] During the turning process of the inner turning seat 2, the edge of the inner turning seat 2 pushes up the connecting spring 62 to bend and stretch. After turning, the cylinder is closed, and under the elastic restoring force of the connecting spring 62, the inner turning seat 2 turns back to a horizontal state, which is convenient for the next turning and swinging to remove the dirt on the filter bag 4.

[0055] Example 4

[0056] like Figure 1-5As shown, based on the structure of Example 1, this embodiment has a cylinder mounting seat 52 fixedly connected to the cylinder of the push cylinder 51, and a plurality of long connecting screws 521 are fixedly assembled and connected to the cylinder mounting seat 52, and the long connecting screws 521 are fastened to the top of the external fixed mounting ring seat 1. In the actual working process, the cylinder is set on the outside of the top of the tank body, and its piston rod is slidably connected to the tank top cover, and the long connecting screws pass through the tank top cover. Intervention can be achieved without opening the water tank cover.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
