Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a bag filter. Background Art

[0002] The bag filter is a new type of filtration system. Inside the bag filter, the filter bag is supported by a metal wire basket. The liquid flows in from the inlet, flows out from the outlet after being filtered by the filter bag, and the impurities are intercepted in the filter bag. It can be used continuously after replacing the filter bag.

[0003] After using for a period of time, the staff needs to clean or replace the filter bag. At this time, the staff needs to open the top cover and take out the whole filter bag from the container. The top cover of the bag filter is locked by the cooperation of nuts and bolts. Therefore, whether opening or closing the cover, the staff needs to loosen and tighten them one by one, which is cumbersome in operation and affects the overall work efficiency of the staff. For this reason, we propose a bag filter to solve the above problems. Summary of the Utility Model

A connecting shaft is inserted into the rotating block, and both ends of the connecting shaft are connected to the inner wall of a fixed block through bearings. The fixed block is connected to the top of the housing. A supporting block is connected to the top of the housing, and a hole is opened in the supporting block. A pull rod is inserted into the hole, and one end of the pull rod is connected to an embedded plate through a bearing. An installation groove adapted to the embedded plate is opened on the lower side of the top cover.

[0007] Preferably, moving blocks are symmetrically connected to the upper and lower ends of the side of the embedded plate, and guide rods are connected to the sides of the moving blocks. Guide grooves adapted to the guide rods are opened in the supporting block. Springs are connected to the sides of the moving blocks, and the other ends of the springs are connected to the inner wall of the supporting block.

[0008] Preferably, a connecting block is connected to the end of the pull rod away from the embedded plate, and the connecting block is arranged in a frame structure.

[0009] Preferably, a rubber ring is arranged below the top cover, and a sealing groove adapted to the rubber ring is opened at the top of the housing.

[0010] Preferably, a clamping groove adapted to the rubber ring is formed at the bottom end of the top cover. Positioning rods are symmetrically inserted on the sides of the top cover, and linkage blocks are connected to the mutually remote sides of the positioning rods. The mutually proximate sides of the positioning rods extend into the rubber ring, and positioning grooves adapted to the positioning rods are formed inside the rubber ring.

[0011] Preferably, a rubber sleeve is glued to the outer surface of the positioning rod, and the outer wall of the rubber sleeve is in close fit with the inner wall of the positioning groove.

[0012] Preferably, the support block is arranged in a Z-shaped structure, and the bottom end of the support block is connected to the side wall of the housing through bolts.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1-5 , a bag filter includes an outer shell 1, a top cover 2 is covered above the outer shell 1, and a rotating block 3 is connected to the side of the top cover 2. A connecting shaft 4 is inserted into the interior of the rotating block 3, and both ends of the connecting shaft 4 are connected to the inner wall of the fixed block 5 through bearings. The fixed block 5 is connected to the top end of the outer shell 1. A support block 6 is connected to the top end of the outer shell 1, and a hole is opened in the interior of the support block 6. A pull rod 7 is inserted into the hole, and one end of the pull rod 7 is connected to an embedded plate 9 through a bearing. An installation groove adapted to the embedded plate 9 is opened on the lower side of the top cover 2.

[0024] Furthermore, referring to Figure 4 , it can be known that the upper and lower ends of the side of the embedded plate 9 are symmetrically connected with moving blocks 10, and a guide rod 11 is connected to the side of the moving block 10. A guide groove adapted to the guide rod 11 is opened in the interior of the support block 6. A spring 15 is connected to the side of the moving block 10, and the other end of the spring 15 is connected to the inner wall of the support block 6. By providing the guide rod 11 and the guide groove, the stable movement requirement of the embedded plate 9 can be met. The spring 15 is sleeved on the outside of the guide rod 11. Through the connection of the guide rod 11, the tightness when the embedded plate 9 is engaged in the top cover 2 can be effectively ensured.

[0025] Furthermore, referring to Figure 4 , it can be known that one end of the pull rod 7 away from the embedded plate 9 is connected with a connecting block 8, and the connecting block 8 is arranged in a frame structure. By providing the connecting block 8 in a frame structure, it is convenient for the staff to pull the movement of the pull rod 7, thereby effectively improving the convenience during the use of the device.

[0026] Furthermore, referring to Figure 2 and Figure 3 , it can be known that a rubber ring 12 is provided below the top cover 2, and a sealing groove adapted to the rubber ring 12 is opened at the top end of the outer shell 1. By providing the rubber ring 12 and the sealing groove in a ring structure, the sealing performance during the connection between the outer shell 1 and the top cover 2 can be effectively ensured.

[0027] Furthermore, referring to Figure 5It can be known that a clamping groove adapted to the rubber ring 12 is opened at the bottom end of the top cover 2. Positioning rods 13 are symmetrically inserted on the side edges of the top cover 2. A linkage block 14 is connected to the side of the positioning rods 13 away from each other. One side of the positioning rods 13 close to each other extends into the rubber ring 12. A positioning groove adapted to the positioning rods 13 is opened inside the rubber ring 12. Through the mutual cooperation of the positioning rods 13 and the positioning groove, it is convenient for the staff to quickly disassemble and replace the damaged and deformed rubber ring 12.

[0028] Further, referring to Figure 5 It can be known that a rubber sleeve is glued to the outer surface of the positioning rod 13, and the outer wall of the rubber sleeve is closely attached to the inner wall of the positioning groove. The rubber sleeve is not shown in the figure. Through the connection of the rubber sleeve, the positioning effect between the positioning rod 13 and the rubber ring 12 can be effectively ensured.

[0029] Further, referring to Figure 4 It can be known that the support block 6 is arranged in a Z-shaped structure. The bottom end of the support block 6 is connected to the side wall of the housing 1 by bolts. Since the support block 6 is arranged in a Z-shaped structure and is combined with the setting of bolts, it is convenient for the staff to disassemble and assemble the support block 6 and the housing 1. When the spring 15 reaches the service life, it is convenient for the staff to remove the support block 6 for replacement, thereby effectively reducing the maintenance cost of this device.

[0030] Working principle: When this utility model is in use, the staff can first place this device at a suitable position, and then connect the corresponding pipeline to the housing 1 to realize the filtration operation of sewage. After using it for a period of time, the staff can first pull the connection block 8, so that the pull rod 7 connected to its side is simultaneously stressed and moves, so as to pull out the embedded plate 9 from the installation groove opened at the bottom end of the top cover 2. At this time, the limit on the top cover 2 can be released. Then the staff can rotate the top cover 2, so that the top cover 2 drives the rotating block 3 and the connecting shaft 4 to rotate under force, so as to open the opening of the housing 1. Then the staff can disassemble the filter bag of the housing 1 for cleaning and replacement. Immediately afterwards, the staff can install the maintained filter bag inside the housing 1, and then rotate the top cover 2 again to make it cover the top of the housing 1 again to realize the quick connection and disassembly operation between the housing 1 and the top cover 2. The above is the whole working principle of this utility model.
