Description

Technical Field

[0001] This utility model relates to the field of graphite heat exchanger technology, specifically a modular graphite heat exchanger that can be quickly disassembled and assembled. Background Technology

[0002] A graphite heat exchanger is a heat exchange device made of impermeable graphite as the base material. The existing graphite heat exchanger mainly consists of a shell, multiple graphite heat exchange blocks, and two end caps. The shell is a whole, the graphite heat exchange blocks are located in the temporal part of the shell, and the end caps are connected to the shell. This has some shortcomings.

[0003] The outer casing is a single piece and cannot be disassembled. This makes it inconvenient to remove the graphite heat exchanger when replacing it later. Furthermore, the connection between the outer casing and the end cover is secured by multiple bolts and nuts, which require multiple turns to secure. Disassembly also requires removing multiple bolts and nuts, which is very troublesome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a modular graphite heat exchanger that can be quickly assembled and disassembled, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a modular graphite heat exchanger that can be quickly disassembled and assembled, comprising two shells, two fixing plates fixed to the outer side walls of the shells, and arc-shaped plates fixed to the left and right sides of the shells, the arc-shaped plates and the fixing plates being fixedly connected, a screw is provided above the fixing plate, and two connecting plates are rotatably connected to the outer side walls of the screw, the bottom of the connecting plates being fixedly connected to the top of the fixing plate above;

[0006] A movable cylinder is screwed to the outer wall of the screw, and multiple fixing blocks are fixed to the outer wall of the movable cylinder. The top of the fixing plate has a through-hole that runs vertically through it. The bottom of the fixing block passes through the through-hole. A movable pressing block is fixed to the right side of the fixing block. Multiple fixing pressing blocks are fixed to the bottom of the fixing plate below. End caps are provided on both the left and right sides of the housing. Multiple rotating rods are rotatably connected inside the end caps.

[0007] Two rotating arc-shaped extrusion blocks are fixed to the outer wall of the rotating rod. Multiple perforations are opened on the left side of the arc plate. Two fixed arc-shaped extrusion blocks are fixed on the side of the arc plate near the shell, outside the perforations. Two baffles are fixed to the inner wall of the shell. Multiple baffle rods are fixed between the two baffles. Baffles are fixed to both ends of the baffles. The baffles and the baffle rods are fixedly connected to the shell. Multiple graphite heat exchange blocks are provided inside the two shells.

[0008] Preferably, a gear ring is rotatably connected to the outer wall of the end cap, and a gear is fixed to the end of the rotating rod away from the housing, with the gear ring and the gear meshing together.

[0009] Preferably, a worm is provided on the outer side of the end cap, and two connecting blocks are rotatably connected to the outer side wall of the worm. The connecting blocks are fixedly connected to the end cap. A worm wheel is rotatably connected to the side of the gear ring away from the housing, and the worm and the worm wheel are meshed together.

[0014] This invention provides a modular graphite heat exchanger that can be quickly assembled and disassembled. Compared with the prior art, it has the following advantages:

[0015] 1. This modular graphite heat exchanger, which can be quickly assembled and disassembled, uses a screw, a moving cylinder, a fixed block, a moving extrusion block, a fixed extrusion block, a rotating rod, a rotating arc-shaped extrusion block, and a fixed arc-shaped extrusion block to place the graphite heat exchange block between two shells. Then, the two shells are joined together, and the fixed block and the moving extrusion block pass through the through-hole. Rotating the screw moves the moving cylinder, the fixed block, and the moving extrusion block, which in turn presses against the fixed extrusion block. This fixes the two fixed plates and the two shells together. Next, the two end caps are joined to the shells, and the rotating rod passes through the through-hole. Rotating the rotating rod moves the rotating arc-shaped extrusion block, which in turn presses against the fixed arc-shaped extrusion block. This fixes the end caps and arc plates together without the need to rotate multiple bolts and nuts, making installation and disassembly very convenient.

[0016] 2. This modular graphite heat exchanger, which can be quickly disassembled and assembled, is equipped with a worm gear, worm shaft, gear ring, and gears. Rotating the worm shaft causes the worm gear to rotate, which in turn causes the gear ring to rotate. The gear ring then causes the gears to rotate, which in turn causes multiple rotating rods to rotate. This allows multiple rotating rods to rotate simultaneously, further facilitating the installation and disassembly of the end cover. Attached Figure Description

[0023] Please see Figures 1-4This utility model provides a technical solution: a modular graphite heat exchanger that can be quickly disassembled and assembled, comprising two shells 1, two fixing plates 9 fixed to the outer side wall of the shell 1, and arc-shaped plates 30 fixed to both the left and right sides of the shell 1, the arc-shaped plates 30 and the fixing plates 9 being fixedly connected, a screw 14 is provided above the fixing plate 9, two connecting plates 15 are rotatably connected to the outer side wall of the screw 14, the bottom of the connecting plates 15 is fixedly connected to the top of the upper fixing plate 9, a movable cylinder 13 is screwed to the outer side wall of the screw 14, multiple fixing blocks 12 are fixed to the outer side wall of the movable cylinder 13, a through-hole 17 is opened at the top of the fixing plate 9, the bottom of the fixing block 12 passes through the through-hole 17, a movable pressing block 11 is fixed to the right side of the fixing block 12, and multiple fixing pressing blocks 10 are fixed to the bottom of the lower fixing plate 9, end caps 5 are provided on both the left and right sides of the shell 1, and multiple rotating rods 26 are rotatably connected inside the end caps 5. Two rotating arc-shaped extrusion blocks 23 are fixed to the outer wall of the 6. Multiple perforations 20 are opened on the left side of the arc plate 30. Two fixed arc-shaped extrusion blocks 22 are fixed on the side of the arc plate 30 near the shell 1 outside the perforations 20. Two baffle strips 19 are fixed to the inner wall of the shell 1. Multiple baffle rods 28 are fixed between the two baffle strips 19. Both ends of the baffle strips 19 are fixed. Two limiting blocks 27 are fixed to the bottom of the upper fixing plate 9. Two limiting holes 29 are opened on the top of the upper fixing plate 9. The limiting blocks 27 are inserted into the limiting holes 29, which can restrict the movement of the two shells 1. Sealing gaskets 16 are fixed to the opposite sides of the upper and lower fixing plates 9 to increase the sealing baffle 21. The baffle 21 and the baffle rods 28 are fixedly connected to the shell 1. Multiple graphite heat exchange blocks 18 are provided inside the two shells 1. This eliminates the need to use multiple bolts and nuts for fixed connection, which is simple and convenient.

[0024] Furthermore, a gear ring 25 is rotatably connected to the outer wall of the end cap 5, and a gear 2 is fixed to the end of the rotating rod 26 away from the housing 1. The gear ring 25 and the gear 2 mesh with each other, allowing multiple rotating rods 26 to rotate simultaneously. A worm 6 is provided on the outer side of the end cap 5, and two connecting blocks 7 are rotatably connected to the outer wall of the worm 6. The connecting blocks 7 are fixedly connected to the end cap 5. A worm wheel 4 is rotatably connected to the side of the gear ring 25 away from the housing 1.

In this way, the end cap 5 and the arc plate 30 are installed and fixed together without the need for multiple bolts and nuts for installation and fixation, which is simple and quick.
