[0023] In this example, the anti-wear mechanism also includes a push rod 11, and the push rod 11 is fixedly installed on the side of the baffle 10 away from the tooth block 9. A spring 12 is sleeved on the outer side of the push rod 11 in the chamber. A baffle rod 13 is provided on one side of the top of the connecting block 5, and the lower end of the baffle rod 13 passes through the connecting block 5 and is connected to a baffle 2 15. A spring 2 16 is sleeved on the outer side of the baffle rod 13 between the baffle 2 15 and the bottom of the connecting block 5. A through hole adapted to the push rod 11 is provided on the side wall of the baffle rod 13, and a through groove adapted to the push rod 11 is provided at one end of the connecting block 5. The upper ends of the two baffle rods 13 are connected by a connecting rod 14, and a pull ring is provided in the middle of the top of the connecting rod 14.

It is easy to use and more practical. In this example, the fixing mechanism includes a fixing seat 17, which is symmetrically arranged above the connecting block 5 on one side of the boiler body 1. A transmission cavity is opened inside the fixing seat 17, and a rotating drum 19 is rotatably installed in the transmission cavity. A gear 20 is sleeved on the outer side of the rotating drum 19, and an L rod 18 is provided on the top of the connecting block 5. A slot connected to the transmission cavity is opened on one side of the fixing seat 17, and a plurality of tooth grooves meshing with the gear 20 are opened on the top of the L rod 18. A spring 21 and a limit block 22 are provided in the rotating drum 19, and the limit block 22 is located on the opposite outer side of the two connecting blocks 5. One end of the limit block 22 passes through the side wall of the connecting block 5 to form a limit groove 24, and one end of the limit block 22 is rotatably connected to a transmission rod 23, and one end of the transmission rod 23 is connected to a push handle. Through the fixing mechanism, the connecting block 5 can be easily and quickly disassembled and installed to replace the connecting block 5. In this example, the connecting shaft of the local gear 6 is rotatably connected to the connecting block 5 through a bearing, the two ends of the spring 12 are respectively fixedly connected to the baffle 10 and the inner wall of the chamber, and the two ends of the spring 2 16 are respectively fixedly connected to the connecting block 5 and the baffle 2 15, so that the elastic force of the spring 12 can be used to provide power for the reset movement of the push rod 11 and the tooth block 9. The installation of the spring 2 16 can reset and limit the blocking rod 13 so that the blocking rod 13 blocks the push rod 11. In this example, the combination of the connecting rod 14 and the blocking rod 13 is in an inverted U shape, the isolation plate 3 is arc-shaped, and the through hole is located below the push rod 11, so as to synchronously drive the two blocking rods 13 to move up and down, and the shape of the isolation plate 3 can be adapted to the water-cooled wall tube body 2. In this example, the rotating drum 19 and the transmission rod 23 are rotatably connected to the fixed seat 17 and the limit block 22 respectively through bearings. The limit groove 24 is a hexagonal prism structure. The two ends of the spring three 21 are fixedly connected to the limit block 22 and the inner wall of the rotating drum 19 respectively to limit the rotating drum 19 and prevent it from rotating, thereby limiting the gear 20 and allowing the gear 20 to be connected and fixed to the L rod 18.

[0024] The working principle of the utility model is as follows: when in use, by using a hook-like tool, the pull ring is hooked and pulled up, so that the pull ring drives the connecting rod 14, and then drives the two connected baffles 13 to move up synchronously, and at the same time, the baffle 13 will drive the baffle plate 15 below and cooperate with the connecting block 5 to squeeze the spring 16, and at the same time, the through hole on the baffle 13 is moved up to be opposite to the push rod 11, and then the guide plate 8 is adjusted according to the impurity material flowing upward through the bottom of the boiler body 1 or flowing downward through the upper part of the boiler body 1. When flowing upward, the guide plate 8 can be pushed to drive the fixed block 7 and the local gear 6 to rotate downward, and at the same time, the rotation of the local gear 6 will cause its teeth to rotate. The extrusion pushes the tooth block 9 to move in the direction away from the local gear 6. At the same time, the tooth block 9 will push the baffle 10 to drive the push rod 11 to move. At the same time, the baffle 10 will squeeze the spring 12, and the end of the push rod 11 away from the baffle 10 will pass through the through hole and insert into the through groove. When the teeth of the extruded tooth block 9 are misaligned with it, the baffle 10 will push the tooth block 9 to reset under the elastic force of the spring 12, so that the tooth block 9 is meshed with the local gear 6. At the same time, the end of the push rod 11 close to the baffle rod 13 will move out of the through hole, and the reciprocating movement is continuously carried out until the guide plate 8 is adjusted to a suitable angle position, and the force applied to the pull ring can be released to make the baffle 12 15 drives the blocking rod 13 to move down and reset under the elastic force of the spring second 16, so that the through hole moves down and is dislocated from the push rod 11, so that the blocking rod 13 blocks one end of the push rod 11, and the position of the guide plate 8 can be restricted and fixed. It is convenient and quick to use and has strong practicality. When the connecting block 5 needs to be disassembled, the push handle can be pushed to drive the transmission rod 23, and then the transmission rod 23 pushes the limit block 22 to move into the rotating drum 19. At the same time, the limit block 22 will squeeze the spring third 21 until the limit block 22 is completely moved into the rotating drum 19, and then the connecting block 5 can be pulled out to drive the L rod 18 to move out of the slot, and then the force applied to the push handle can be released to reset the limit block 22 and insert it. The corresponding limit groove 24 is inserted into the corresponding limit groove 24. When installing the connecting block 5, the above disassembly steps can be repeated. After the limit block 22 is moved into the rotating drum 19, one end of the L rod 18 is inserted into the slot so that the tooth groove on the bar engages with the gear 20, and the gear 20 is driven to drive the rotating drum 19 to rotate until the L rod 18 is fully inserted into the slot. The thrust of the spring three 21 is released to insert the limit block 22 into the limit groove 24, so as to realize the limit fixation of the rotating drum 19, thereby realizing the connection and fixation between the L rod 18 and the gear 20, thereby completing the installation and fixation of the connecting block 5, and the connecting block 5 can be conveniently disassembled or installed to facilitate its replacement, which is more practical.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
