The inner distribution plate is then horizontally engaged inside the main support tank. When the inner distribution plate is pushed downwards to the limiting groove position, the top spring causes one end of the insertion side block to extend from the opening of the movable side groove. This extended end is then inserted into the limiting groove, securing the inner distribution plate. Finally, the top of the connecting bottom pipe is aligned with the bottom of the main support tank, causing the sealing ring to engage inside the sealing groove, creating a seal. This is achieved through a fixed connecting ring. After being fixedly connected to the bottom mounting ring by threads, it forms an integral sealed installation. After the top of the main support tank is fixedly connected to the material inlet pipe, the material enters the interior of the main support tank through the pipe. Under the guidance of the internal guide plate, it falls downward into the position between the vertical baffle and the guide inclined plate. Then, through the water at the bottom, it enters the other side of the vertical baffle and pushes the falling material into the discharge side hole. Finally, the material is guided into the interior of the heat exchanger for recycling through the discharge connecting pipe on the side. The split structure facilitates subsequent disassembly, replacement, and maintenance. At the same time, the combination of the separate flushing circulation structure makes the return of material more efficient and comprehensive. Attached Figure Description

The inner distribution plate 18 is horizontally snapped into the main support tank 1. When the inner distribution plate 18 is pushed downwards to the limiting inner groove 23, the top spring 21 causes one end of the insertion side block 22 to extend from the opening of the movable side groove 20. This extended end is then inserted into the limiting inner groove 23, thus fixing the inner distribution plate 18. Finally, the top of the connecting bottom pipe 5 is connected to the bottom of the main support tank 1, thus sealing the ring. The 14-clamp fitting is set inside the sealing end groove 13 to form a sealing effect. After being fixedly connected to the bottom mounting ring 3 by the fixing ring 6, an overall sealed installation operation is formed. After the top of the main support tank 1 is fixedly connected to the material inlet pipe, the material enters the main support tank 1 through the pipe. Under the guidance of the internal guide top plate 15, it falls downward into the position between the vertical partition 16 and the guide inclined plate 17. Then, through the water at the bottom, it enters the other side of the vertical partition 16 and pushes the falling material into the discharge side hole 12. Finally, the material is guided into the heat exchanger for recycling through the side discharge connecting pipe 10.
