Description

Technical Field

[0001] This invention relates to the field of condenser technology, and more particularly to a shell-and-tube condenser. Background Technology

[0002] In the field of chemical production, reflux condensation is commonly used to return reactants to the reactor for further reaction. Shell-and-tube condensers can condense the vapors that evaporate during the reaction, thereby improving product yield.

[0003] Existing shell-and-tube condensers have the following problems in use: 1. These condensers are not easy to install quickly and securely, resulting in low operational flexibility. 2. The vibration damping effect is poor during operation, making them susceptible to damage. Unstable cooling medium pressure during water exchange causes vibration, which can lead to collisions between the base and the condenser shell, damaging the equipment and reducing its lifespan. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shell-and-tube condenser.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shell-and-tube condenser includes a base. The base has a groove on its top and through holes on both sides. A crossbar is movably installed in each of the through holes. A mounting block is fixedly installed at the end of each crossbar that is close to the other. A shell-and-tube condenser body is located between the two mounting blocks. Each mounting block has a buffer cavity, and two sliding rods are fixedly installed in each buffer cavity. The top of each mounting block has a movable hole communicating with the buffer cavity. A buffer rod is movably installed in any one of the movable holes. Two sliding sleeves are slidably fitted onto any one of the sliding rods. A buffer plate adapted to the shell-and-tube condenser body is fixedly installed at the top of each buffer rod. A buffer connecting rod is rotatably installed between each sliding sleeve and its corresponding buffer rod. The bottom of each mounting block... Each component is fixedly equipped with a connecting plate, and each connecting plate has a movable hole. A movable block is movably installed on each of the two movable holes. A rotating rod is rotatably installed on one inner wall of the groove, and two metal blocks are fixedly installed thereon. A worm gear is rotatably installed on each of the two metal blocks. A worm wheel and a connecting rod are fixedly sleeved on each of the two rotating rods. The two connecting rods are rotatably connected to the corresponding movable blocks. The two worm gears are respectively meshed with the corresponding worm wheels, and the ends of the two worm gears that are close to each other are fixedly sleeved with second bevel teeth. A round rod is rotatably installed on the bottom of the base. A first bevel tooth that meshes with the two second bevel teeth is fixedly sleeved on the top of the round rod. End caps are fixedly installed at both ends of the shell-and-tube condenser body, and a water outlet pipe is fixedly installed on the top. A condensate outlet and a gas inlet pipe are fixedly installed on both sides, respectively.

[0007] Preferably, two slots are provided on the top of each of the two mounting blocks, and matching slots are fixedly installed on both sides of the bottom of the shell-and-tube condenser body.

[0008] Preferably, a crank handle is fixedly installed at the bottom end of the round rod.

[0009] Preferably, a return spring is sleeved on each of the two crossbars, with one end of the two return springs fixed on the corresponding crossbar and the other end fixed on the inner wall of the corresponding through hole.

[0010] Preferably, a second buffer spring is sleeved on each buffer rod, one end of the second buffer spring is fixed on the corresponding buffer rod, and the other end is fixed on the inner wall of the corresponding movable hole, and a first buffer spring is fixedly sleeved on each sliding rod and the corresponding sliding sleeve.

[0011] Preferably, protective shells are fixedly installed on both sides of the base.

[0012] Preferably, mounting ears are fixedly installed at all four corners of the bottom of the base.

[0013] Preferably, a fixing rod is fixedly installed at the bottom of the base, and a rotating hole is opened on the fixing rod. A rotating rod is rotatably installed in the rotating hole, and a metal rotating rod is fixedly sleeved on the rotating rod. A limit block is fixedly installed on the side of the metal rotating rod near the crank handle. Multiple limit grooves that are adapted to the limit blocks are opened at equal intervals around the round rod at the bottom of the crank handle. A torsion spring is sleeved on the rotating rod, with one end of the torsion spring fixed on the rotating rod and the other end fixed on the inner wall of the rotating hole.

[0014] In this invention, the shell-and-tube condenser is first placed on top of a base. Then, a metal rotating rod is pulled downwards, causing the limiting block to disengage from the limiting groove on the crank handle, thus removing the crank handle from its fixed position. Rotating the crank handle then drives the first bevel gear to rotate, which in turn drives the two second bevel gears, which in turn drive the two worm gears. These worm gears, in turn, drive the two worm wheels, which in turn drive the two connecting rods. These connecting rods pull two movable blocks to slide within movable holes, causing the two connecting plates to move towards each other, and consequently, the two mounting blocks to move towards each other. This causes the slots on the two mounting blocks to engage with the corresponding slots on the shell-and-tube condenser body, thus fixing the shell-and-tube condenser body in place. Finally, releasing the metal rotating rod allows it to reset under the action of a torsion spring, causing the limiting block to re-engage into the limiting groove on the crank handle, thus fixing the crank handle and the positions of the two mounting blocks.

[0015] During routine use of the shell-and-tube condenser, the condenser body presses against the bottom cooling buffer plate. This pressure, in turn, compresses the corresponding second buffer spring, and further compresses the two corresponding buffer linkages. These linkages then pull the corresponding sliding sleeves, causing the first buffer spring to exert its elastic force. This process effectively dampens the vibrations of the shell-and-tube condenser, increasing its service life. This invention features a simple structure and is easy to use. The described shell-and-tube condenser facilitates quick installation and fixation, provides excellent vibration damping, and further extends the condenser's lifespan. Attached Figure Description

Each of the two worm gears 20 meshes with the corresponding worm wheel 16 and has a second bevel tooth 30 fixedly sleeved at one end that is close to each other. A round rod 31 is rotatably installed at the bottom of the base 1. The top of the round rod 31 is fixedly sleeved with a first bevel tooth 29 that meshes with the two second bevel teeth 30. Both ends of the shell-and-tube condenser body 8 are fixedly installed with end caps 9, and a water outlet pipe 12 is fixedly installed on the top. A condensate outlet 10 and a gas inlet pipe 35 are fixedly installed on both sides respectively.

[0026] In this invention, two slots 7 are provided on the top of each of the two mounting blocks 3, and two matching slot blocks 11 are fixedly installed on both sides of the bottom of the shell-and-tube condenser body 8. The opposite movement of the two connecting plates 15 can drive the opposite movement of the two mounting blocks 3, so that the slots 7 on the two mounting blocks 3 respectively engage in the corresponding slots 11 on the shell-and-tube condenser body 8, thereby installing and fixing the shell-and-tube condenser body 8.

[0027] In this invention, a crank handle 32 is fixedly installed at the bottom end of the round rod 31, which facilitates the rotation of the round rod 31.

[0028] In this invention, a return spring 14 is sleeved on each of the two crossbars 13.

[0034] Reference Figure 1-6A shell-and-tube condenser includes a base 1. The top of the base 1 has a groove, and both sides have through holes. A crossbar 13 is movably installed in each of the two through holes. The ends of the two crossbars 13 closest to each other are fixed with mounting blocks 3 by bolts. A shell-and-tube condenser body 8 is located between the two mounting blocks 3, and each mounting block 3 has a buffer cavity 5. Two sliding rods 27 are fixedly installed in each of the two buffer cavities 5 by bolts. The top of each mounting block 3 has a movable hole 23 communicating with the buffer cavity 5. A buffer rod 22 is movably installed in any one of the movable holes 23. Two sliding sleeves 26 are slidably sleeved on each sliding rod 27. A buffer plate 21, adapted to the shell-and-tube condenser body 8, is fixedly installed at the top of each buffer rod 22 by bolts. A buffer connecting rod 24 is rotatably installed between each sliding sleeve 26 and the corresponding buffer rod 22 via bearings. The bottom of each mounting block 3 is fixed with bolts. The condenser is equipped with connecting plates 15, each with a movable hole 18. A movable block 17 is movably installed in each of the two movable holes 18. A rotating rod is rotatably installed on one side of the inner wall of the groove via a bearing, and two metal blocks are fixedly installed by bolts. A worm gear 20 is rotatably installed on each of the two metal blocks via a bearing. A worm wheel 16 and a connecting rod 19 are fixedly sleeved on each of the two rotating rods. The two connecting rods 19 are rotatably connected to the corresponding movable blocks 17. The two worm gears 20 are respectively meshed with the corresponding worm wheels 16, and the ends of the two worm gears 20 that are close to each other are fixedly sleeved with second bevel teeth 30. A round rod 31 is rotatably installed on the bottom of the base 1 via a bearing. A first bevel tooth 29 that meshes with the two second bevel teeth 30 is fixedly sleeved on the top of the round rod 31. End caps 9 are fixedly installed on both ends of the shell-and-tube condenser body 8 via bolts, and a water outlet pipe 12 is fixedly installed on the top via bolts. A condensate outlet 10 and a gas inlet pipe 35 are fixedly installed on both sides via bolts.

[0035] In this invention, two mounting blocks 3 each have two slots 7 on their tops. The bottom sides of the shell-and-tube condenser body 8 are bolted with matching locking blocks 11. A crank handle 32 is bolted to the bottom of the round rod 31. Return springs 14 are sleeved on both crossbars 13, with one end fixed to the corresponding crossbar 13 and the other end fixed to the inner wall of the corresponding through hole. A second buffer spring 28 is sleeved on any buffer rod 22, with one end fixed to the corresponding buffer rod 22 and the other end fixed to the inner wall of the corresponding movable hole 23. Any sliding rod 27 is fixedly sleeved with the corresponding sliding sleeve 26. A first buffer spring 25 is connected. Protective shells 6 are fixedly installed on both sides of the base 1 by bolts. Mounting ears 2 are fixedly installed at the four corners of the bottom of the base 1 by bolts. A fixing rod 4 is fixedly installed at the bottom of the base 1 by bolts. A rotating hole is opened on the fixing rod 4. A rotating rod 34 is rotatably installed in the rotating hole through a bearing. A metal rotating rod 33 is fixedly sleeved on the rotating rod 34. A limit block is fixedly installed on the side of the metal rotating rod 33 near the crank handle 32 by bolts. Multiple limit grooves that are adapted to the limit blocks are opened at equal intervals around the round rod 32 at the bottom of the crank handle 32. A torsion spring is sleeved on the rotating rod 34. One end of the torsion spring is fixed on the rotating rod 34, and the other end is fixed on the inner wall of the rotating hole.

[0036] In this invention, the shell-and-tube condenser body 8 is first placed on top of the base 1. Then, the metal rotating rod 33 is pulled down, causing the limiting block to disengage from the limiting groove on the crank handle 32, thus removing the crank handle 32 from its fixation. Rotating the crank handle 32 then drives the first bevel gear 29 to rotate. The first bevel gear 29 drives the two second bevel gears 30 to rotate, which in turn drives the two worm gears 20 to rotate. The two worm gears 20 drive the two worm wheels 16 to rotate, which in turn drives the two connecting rods 19 to rotate. The two connecting rods 19 pull the two movable blocks 17 in a haptic motion. Sliding within the moving hole 18 causes the two connecting plates 15 to move towards each other, which in turn causes the two mounting blocks 3 to move towards each other. This allows the slots 7 on the two mounting blocks 3 to engage with the corresponding slots 11 on the shell-and-tube condenser body 8, thus installing and fixing the shell-and-tube condenser body 8. Then, by releasing the metal rotating rod 33, the metal rotating rod 33 is reset by the torsion spring on the rotating rod 34, causing the limiting block to re-engage in the limiting groove on the crank handle 32, thus fixing the crank handle 32 and fixing the position of the two mounting blocks 3.

[0037] During routine use, the shell-and-tube condenser body 8 is subjected to shock absorption and cushioning by pressing against the bottom cooling buffer plate 21. The buffer plate 21 compresses the corresponding second buffer spring 28, and the buffer plate 21 also compresses the two corresponding buffer connecting rods 24. The buffer connecting rods 24 then compress the corresponding sliding sleeves 26, which in turn pull the corresponding first buffer spring 25. This process increases the service life of the shell-and-tube condenser body 8. This invention has a simple structure and is easy to use. The described shell-and-tube condenser is easy to install and fix quickly, and has good shock absorption and cushioning effects, thus extending the condenser's service life.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
