Description

Technical Field

[0001] This application relates to the field of filter bag holder technology, and in particular to a V-shaped filter bag holder with a sealing reinforcement structure. Background Technology

[0002] V-shaped filter bags are high-efficiency filtration devices that use V-shaped filter bags as the core filtration element. The V-shaped design of the filter bag expands the filtration area, and the special frame achieves precise fixation and sealing. They are widely used for the interception of impurities in liquids and gases.

[0003] When installing V-shaped filter bags, the bag opening is usually passed through the inlet of the frame, and the elastic sealing ring of the bag opening is aligned with the positioning groove at the top of the space. Since there is only one frame, the bag opening directly contacts the top of the frame, and there is no capping operation at the top of the bag opening. In actual use, if the bag opening tilts up, the sealing effect will be poor.

[0004] Therefore, those skilled in the art have provided a V-shaped filter bag holder with a sealing reinforcement structure to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a V-shaped filter bag holder with a sealing and reinforcing structure. Through a step-by-step operation of inserting the bag opening into the inlet, rolling it up to fit the frame, and pressing the sealing plate together, the top opening of the V-shaped filter bag can be stably fixed between the frame and the sealing plate.

[0006] The V-shaped filter bag holder with a sealing and reinforcement structure provided in this application adopts the following technical solution:

[0007] A V-shaped filter bag holder with a sealing reinforcement structure includes a filter bag holder body. The filter bag holder body includes a frame, three inlets extending through the upper end of the frame, and three triangular side plates fixed on both sides of the bottom end of the frame. A sealing plate is detachably attached to the upper end of the frame, and the sealing plate has three through holes that mate with the inlets. Several pressure grooves are formed on the upper surface of the frame, and several pressure posts that mate with the pressure grooves are fixed on the lower surface of the sealing plate. A limiting plate is fixed between two of the side plates, and a first clamping plate and a second clamping plate are slidably provided on the upper end of the limiting plate.

[0008] In this invention, by moving the first clamping plate and the second clamping plate closer together, a stable clamping can be formed on the bottom of the V-shaped filter bag. Combined with the fixing structure at the top, the filter bag is fixed in all directions on the filter bag frame body, which can prevent the filter bag from shifting or shaking due to fluid impact during the filtration process and extend the service life of the filter bag.

[0009] Preferably, there are three limiting plates, and the three limiting plates are located at the bottom of the three inlets respectively.

[0010] Preferably, the bottom end of the limiting plate is fixed with a T-shaped base, and the base is slidably connected with two sliding rods. The two sliding rods are respectively fixed with a sliding block and a movable block. The sliding block is fixedly connected to the first clamping plate, and the movable block is fixedly connected to the second clamping plate.

[0011] Preferably, a screw is rotatably connected to the bottom end of the base, and both the sliding block and the movable block are threadedly connected to the screw, with the screw having opposite thread directions on both sides of the base.

[0012] In this invention, the screw threads on both sides of the base are opposite in direction. Rotating the screws will cause the sliding block, movable block and clamping plate to move closer together. No additional tools are required, which simplifies the installation and adjustment process of the bottom of the V-shaped filter bag. It can not only quickly replace the filter bag, but also flexibly adjust the clamping force according to the filter bag specifications, thus improving work efficiency.

[0013] Preferably, each of the four corners of the sealing plate is fixed with a fixing plate, and the fixing plate is threadedly connected to the frame with bolts.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] ① This application, through a step-by-step operation of inserting the bag opening into the inlet, rolling and fitting it to the frame, and pressing the sealing plate together, can stably fix the top opening of the V-shaped filter bag between the frame and the sealing plate. The clear installation steps can reduce the difficulty of operation, ensure the accurate installation position of the bag opening, and lay a solid foundation for subsequent filtration operations.

[0016] ② By utilizing the cooperation between the bottom pressure column of the sealing plate and the upper pressure groove of the frame, the bag opening can be tightly pressed between the two, effectively improving the sealing performance between the upper end of the V-shaped filter bag and the frame. This fundamentally avoids gaps between adjacent filter bags due to poor sealing, ensuring no leakage or bypass of fluid during the filtration process and improving filtration efficiency.

[0022] 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.

[0023] like Figure 1-4 As shown, this application discloses a V-shaped filter bag holder with a sealing reinforcement structure, including a filter bag holder body. The filter bag holder body includes a frame 1, three inlets 12 penetrating through the upper end of the frame 1, and three triangular side plates 9 fixed on both sides of the bottom end of the frame 1. The frame 1 is used to support the upper end of the filter bag. A sealing plate 2 is detachably attached to the upper end of the frame 1. The sealing plate 2 has three through holes 10 that cooperate with the inlets 12. Several pressure grooves 11 are formed on the upper surface of the frame 1. Several pressure posts 13 that cooperate with the pressure grooves 11 are fixed on the lower surface of the sealing plate 2. A limiting plate 3 is fixed between the two side plates 9. A first clamping plate 4 and a second clamping plate 6 are slidably provided on the upper end of the limiting plate 3.

[0024] By adopting the above technical solution: First step: Pass the top openings of the three V-shaped filter bags through the three inlets 12 respectively, and then roll the openings of the V-shaped filter bags from the inside out to the upper surface of the frame 1, so that the outer surface of the bag openings fits with the pressure groove 11 at the upper end of the frame 1. Then press the sealing plate 2 on the upper end of the frame 1, so that the pressure column 13 at the bottom end of the sealing plate 2 presses the bag openings into the pressure groove 11 until the openings of the V-shaped filter bags are pressed between the frame 1 and the sealing plate 2, thus installing the V-shaped filter bags;

[0025] Step 2: By cooperating with the pressure column 13 and the pressure groove 11, the bag opening is tightly attached between the sealing plate 2 and the frame 1, which improves the sealing effect between the upper end of the V-shaped filter bag and the frame 1 and avoids gaps between adjacent V-shaped filter bags.

[0026] Step 3: After the bag opening is installed, insert the bottom of the V-shaped filter bag between the first clamping plate 4 and the second clamping plate 6. Move the first clamping plate 4 and the second clamping plate 6 closer together until the bottom of the V-shaped filter bag is clamped, so that the V-shaped filter bag is installed on the filter bag frame body.

[0027] In order to clamp the bottom of the V-shaped filter bag in the three inlets 12, there are three limiting plates 3, which are located at the bottom of the three inlets 12 respectively.

[0028] To support the first clamping plate 4 and the second clamping plate 6, a T-shaped base 14 is fixed to the bottom of the limiting plate 3. The base 14 is slidably connected to two sliding rods 15. The two sliding rods 15 are respectively fixed with a sliding block 5 and a movable block 16. The sliding block 5 is fixedly connected to the first clamping plate 4, and the movable block 16 is fixedly connected to the second clamping plate 6. By moving the sliding block 5 and the movable block 16 on the two sliding rods 15 on the base 14, the first clamping plate 4 and the second clamping plate 6 are moved, thereby adjusting the position of the first clamping plate 4 and the second clamping plate 6.

[0029] To enable the first clamping plate 4 and the second clamping plate 6 to move and clamp the bottom of the V-shaped filter bag, a screw 17 is rotatably connected to the bottom of the base 14. The sliding block 5 and the movable block 16 are both threadedly connected to the screw 17. The screw 17 is located on both sides of the base 14 with opposite thread directions. The rotation of the screw causes the sliding block 5 and the movable block 16 to move in opposite directions. When the bottom of the V-shaped filter bag is inserted between the first clamping plate 4 and the second clamping plate 6, the screw is rotated to move the sliding block 5 and the movable block 16 closer together, which in turn moves the first clamping plate 4 and the second clamping plate 6 closer together to clamp the bottom of the V-shaped filter bag, facilitating the installation of the bottom of the V-shaped filter bag.

[0030] In order to fix the sealing plate 2 on the frame 1 and clamp the bag opening of the V-shaped filter bag, the four corners of the sealing plate 2 are fixed with fixing plates 8, and the fixing plates 8 are threadedly connected to the frame 1 with bolts 7; when the sealing plate 2 and the frame 1 clamp the bag opening of the V-shaped filter bag, the four bolts 7 can be tightened to connect with the frame 1, fix the sealing plate 2 and the frame 1, and clamp the V-shaped filter bag.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: The top openings of the three V-shaped filter bags are passed through the three inlets 12 respectively. Then, the openings of the V-shaped filter bags are rolled up from the inside to the outside onto the upper surface of the frame 1, so that the outer surface of the bag opening fits against the pressure groove 11 at the upper end of the frame 1. Then, the sealing plate 2 is pressed onto the upper end of the frame 1, so that the pressure column 13 at the bottom end of the sealing plate 2 presses the bag opening into the pressure groove 11 until the opening of the V-shaped filter bag is pressed between the frame 1 and the sealing plate 2, thus installing the V-shaped filter bag.
