Description

Technical Field

[0001] The utility model relates to the technical field of filter frameworks, and more specifically to a low-resistance bag filter framework structure. Background Art

[0002] Bag filter is a kind of equipment for gas filtration and purification. It is often composed of several filter bags combined into a group, and several groups into one device. Bag filter is mainly composed of filter bags and their frames, shells, cleaning devices, ash hoppers and ash discharge valves.

[0003] When the existing bag filter is used, when filtering the gas through the filter bag, the gas first enters the filter tube, then enters from the open filter bag, and disperses to the surroundings, flowing from the inside of the filter bag to the outside to achieve filtration, impurities remain in the filter bag, and the purified gas flows to the outside.

[0004] However, in actual use, as the gas passes through the filter cartridge and enters the filter bag, it will exert a strong impact on the filter bag, and the bottom of the filter bag is usually flat, which will produce greater resistance and easily cause the filter bag to rupture, affecting the service life of the filter bag. Utility Model Content

[0005] The utility model provides a low-resistance bag filter skeleton structure, which aims to solve the problem that when the existing bag filter is in use, gas will produce impact force on the filter bag, generate greater resistance, cause damage to the filter bag, and shorten the service life of the filter bag.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-resistance bag filter skeleton structure, including a frame, a plurality of supporting skeletons are arranged at the bottom of the frame, a fixed frame is arranged inside the frame, a plurality of filter bags are arranged inside the fixed frame, the bottoms of the plurality of filter bags are all located inside the supporting skeleton, a movable component is arranged between the fixed frame and the frame, and the movable component is used to protect the filter bags; the movable component includes a connecting frame, the connecting frame is located outside the fixed frame and is fixedly connected to the fixed frame, a movable groove is opened on the inner wall of the frame, the connecting frame is located inside the movable groove, a plurality of telescopic rods are arranged on both sides of the connecting frame, and one end of the plurality of telescopic rods is connected to the inner wall of the movable groove; springs are sleeved on the outer sides of the plurality of telescopic rods, and the two ends of the plurality of springs are respectively connected to the surface of the connecting frame and the inner wall of the movable groove.

[0007] The adoption of the above technical solution is helpful to reduce the resistance experienced by the filter bag and prevent the filter bag from being damaged.

[0008] In a preferred embodiment, a plurality of T-shaped baffles are provided inside the fixed frame, a plurality of filter bags are provided with mounting frames on top, the plurality of mounting frames are located on the top of the fixed frame, and the mounting frame is flush with the T-shaped baffles and the fixed plate; a fixing plate is provided on the top of two sides of the fixed frame, and a supporting plate is provided on the top of the other two sides of the fixed frame, and the two supporting plates are perpendicular to the fixed plates; two fixing plates are provided with two card slots on the surfaces, movable plates are hinged on the tops of the two support plates, movable plates are provided on the tops of the two movable plates, and clamping rods are provided on the bottoms of the two movable plates, and the bottoms of the two clamping rods pass through the surface of the movable plate and are clamped with the card slots.

[0009] The adoption of the above technical solution is conducive to fixing the filter bag and improving the stability of the filter bag.

[0010] In a preferred embodiment, a plurality of threaded holes are provided on the bottom surface of the frame and the surfaces of the plurality of support frames, a screw is provided between each of the threaded holes, and the plurality of support frames are connected to the frame by screws.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model arranges a moving assembly and a supporting frame, and places the filter bag inside the supporting frame. Since the bottom of the supporting frame is conical, the resistance to the filter bag can be preliminarily reduced. When the filter bag is subjected to resistance, power is generated on the fixed frame, so that the fixed frame drives the connecting frame to swing inside the moving groove on the inner wall of the frame, so that the spring and the telescopic rod are compressed or stretched. Through the elasticity of the spring, a rebound power can be generated on the connecting frame, and the fixed frame can be driven to repeatedly swing along the inside of the frame, which can further reduce the resistance to the filter bag, avoid damage to the filter bag, and increase the service life of the filter bag.

[0014] 2. The utility model sets a fixed plate and a supporting plate, rotates the movable plate on the supporting plate, makes the movable plate and the installation frame on the top of the filter bag in a vertical state, then presses the movable plate on the top of the movable plate to engage the two clamping rods at its bottom with the clamping grooves on the surface of the fixed plate, thereby limiting the two ends of the installation frame, fixing the filter bag, and improving the stability of the filter bag.

[0024] In this embodiment, the implementation scenario is specifically as follows: when the filter bag 4 is subjected to impact force, it drives the mounting frame 13 to shake inside the frame 1, causing the connecting frame 51 to slide inside the movable groove 52, causing the spring 53 to expand and contract, thereby reducing the resistance exerted on the filter bag 4.

[0025] For further information, please refer to the attached manual. Figure 2 , 35. A plurality of T-shaped baffles 12 are arranged inside the fixed frame 3, and a plurality of installation frames 13 are arranged on the tops of the filter bags 4. The plurality of installation frames 13 are located on the tops of the fixed frame 3, and the installation frames 13, the T-shaped baffles 12 and the fixed plates 6 are all flush with each other; a fixed plate 6 is arranged on the tops of two sides of the fixed frame 3, and a support plate 7 is arranged on the tops of the other two sides of the fixed frame 3, and the two support plates 7 are perpendicular to the fixed plates 6; two fixing plates 6 have two card slots 8 on the surfaces of the two fixing plates 6, and movable plates 9 are hingedly arranged on the tops of the two support plates 7, and movable plates 10 are arranged on the tops of the two movable plates 9, and clamping rods 11 are arranged on the bottoms of the two movable plates 10, and the bottoms of the two clamping rods 11 penetrate the surface of the movable plate 9 and are clamped with the card slots 8.

[0026] In this embodiment, the implementation scenario is specifically as follows: the installation frame 13 is placed between two T-shaped baffles 12, the installation frame 13 can be initially limited, and then the movable plate 9 is rotated to make the clamping rod 11 engage with the clamping slot 8, the installation frame 13 can be secondarily limited, and the filter bag 4 can be fixed.

[0027] For further information, please refer to the attached manual. Figure 2 A plurality of threaded holes are provided on the bottom surface of the frame 1 and the surfaces of the plurality of support frames 2 , a screw 14 is provided between each of the two threaded holes, and the plurality of support frames 2 and the frame 1 are connected by the screws 14 .

[0028] In this embodiment, the specific implementation scenario is: by removing the screws 14 between one of the supporting skeletons 2 and the frame 1, one of the supporting skeletons 2 can be removed separately.

[0029] Working principle: First, place the filter bag 4 between the two T-shaped baffles 12 inside the fixed frame 3, and make the installation frame 13 on the top of the filter bag 4 located on the top of the fixed frame 3. Since the bottom of the installation frame 13 contacts the surface of the frame 1, the filter bag 4 can be initially fixed. Then rotate the movable plate 9 on the top of the support plate 7 to make the movable plate 9 and the installation frame 13 in a vertical state. Then press the movable plate 10 on the top of the support plate 7 to drive the two clamping rods 11 at the bottom to clamp with the clamping grooves 8 on the surface of the fixed plate 6. The two ends of the installation frame 13 can be limited, and then the filter bag 4 can be fixed for a second time. The filter bag 4 can be fixed inside the fixed frame 3, which can improve the stability of the filter bag 4.

[0030] Then, multiple support frames 2 are installed on the bottom of the frame 1 through screws 14, so that the filter bag 4 is located inside the support frame 2, and the gas enters through the installation frame 13 on the top of the filter bag 4. Because the cross-section of the support frame 2 is set to be conical, the resistance of the gas to the filter bag 4 can be preliminarily reduced. Secondly, when the filter bag 4 is subjected to impact force, power is generated for the fixed frame 3, so that the fixed frame 3 drives the outer connecting frame 51 to slide up and down inside the moving groove 52 on the inner wall of the frame 1, so that the telescopic rod and the spring 53 are compressed or stretched. Through the elasticity of the spring 53, a rebound power can be generated for the connecting frame 51, which can drive the fixed frame 3 to move repeatedly inside the frame 1, thereby further reducing the resistance to the filter bag 4, avoiding the filter bag 4 from being directly subjected to impact force, and reducing the probability of damage to the filter bag 4. The utility model, through the support frame 2 set to be conical and the springs 53 on both sides of the connecting frame 51, can achieve secondary protection for the filter bag 4, reduce the resistance to the filter bag 4, and increase the service life of the filter bag 4.

[0031] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
