[0004] However, in the prior art, although the above patent has the above technical advantages, the disadvantage is that some fluids may be mixed with more impurities. When they flow in the shell and tube heat exchanger, the impurities in the fluid are easy to stick to the inner wall of the shell or the fluid outlet. When the impurities accumulate at the fluid outlet for a long time, it may cause the subsequent fluid to be difficult to flow out of the heat exchanger. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model adopts the following technical solution to solve the technical problems: an anti-blocking shell and tube heat exchanger, comprising an outer jacket, the inner wall of the outer jacket is fixedly connected with an inlet pipe 1, the outside of the inlet pipe 1 is provided with an inlet pipe 2, the bottom end of the inlet pipe 2 is fixedly connected with an inner jacket, the outer surface of the inner jacket is fixedly connected with the inner surface of the outer jacket, the inner surface of the outer jacket is rotatably connected with a rotating sleeve, the inner and outer walls of the rotating sleeve are rotatably connected with a sealing ring, the outer surface of the rotating sleeve is fixedly connected with a swing mechanism, stirring rods are evenly distributed on the inner wall of the rotating sleeve, the inner wall of the inner jacket is fixedly connected with an outlet pipe 2, the inner wall of the outer jacket is fixedly connected with an outlet pipe 1, the inner wall of the outlet pipe 1 is slidably connected with an anti-blocking mechanism, fluid 1 and fluid 2 flow out from the outlet pipe 1 and the outlet pipe 2 respectively through the anti-blocking mechanism, and the operator can rotate the anti-blocking mechanism at any time.

[0006] Preferably, the anti-blocking mechanism includes a lifting tube, the top end of which is rotatably connected to a baffle rod, a through groove is provided on the outside of the baffle rod, and the through groove is opened in the wall of the lifting tube. Rotating the lifting tube causes the baffle rod to rotate to break up possible accumulated sediment, and the sediment then flows out from the through groove or around the top end of the lifting tube.

[0007] Preferably, a clamping plate is fixedly connected to the bottom end of the lifting tube, and the outer surface of the clamping plate is slidably connected to the inner surface of the outlet pipe one. An anti-blocking mechanism is also provided inside the outlet pipe two. Before rotating the anti-blocking mechanism, the clamping plate is pulled out of the outlet pipe one or the outlet pipe two.

[0008] Preferably, the swing mechanism includes a fixed rod, the outer surface of the fixed rod is slidably connected to a first connecting belt, the outer surface of the first connecting belt is fixedly connected to a rotating rod, the outer surface of the rotating rod is threadedly connected to a first telescopic tube, and the end of the first telescopic tube away from the first connecting belt is fixedly connected to a motor, and when the motor is activated, the first telescopic tube rotates.

[0010] Preferably, the inner surface of the second connecting belt is slidably connected to the outer surface of the fixed rod, the outer surface of the rotating rod is fixedly connected with a telescopic block, and the top of the telescopic block is also fixedly connected to the outer surface of the rotating rod. When the rotating rod rotates the rotating sleeve between the outer sleeves toward the direction of the first connecting belt through the first connecting belt and the fixed rod, the second connecting belt is driven and pulls up the rotating rod, and the length of the telescopic block becomes longer.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model is provided with an anti-blocking mechanism, and the operator can rotate the anti-blocking mechanism at any time. First, the card plate is pulled out from the outlet pipe 1 or the outlet pipe 2, and then the card plate is rotated to drive the lifting pipe to rotate, so that the baffle rod at the top rotates, and the baffle rod breaks up the sediment that may be accumulated at the inner opening of the outlet pipe 1 and the outlet pipe 2. The sediment then flows out from the through groove or the surroundings of the top of the lifting pipe through the outlet pipe 1 and the outlet pipe 2, thereby solving the problem that when the debris in the fluid accumulates at the outlet pipe opening, it affects the fluid flow out of the heat exchanger.

[0013] 2. The utility model provides a swing mechanism, and the motor works to make the first telescopic tube rotate. The first telescopic tube and the second telescopic tube are connected by a toothed belt, so that the second telescopic tube rotates with the first telescopic tube and has the same direction. Since the front end of the first telescopic tube is threadedly connected to the rotating rod, when the first telescopic tube no longer moves on the rotating rod, the rotating rod rotates with the first telescopic tube. Since the thread on the rotating rod is in opposite directions to the thread on the rotating rod, the rotating second telescopic tube is contracted without driving the rotating rod to rotate. At this time, the rotating rod rotates the rotating sleeve between the outer sleeves in the direction of the first connecting belt and the fixed rod. The sealing ring provided at the connection between the rotating sleeve and the outer sleeve can prevent fluid from overflowing. At this time, the second connecting belt is driven and the rotating rod is pulled up, so the length of the telescopic block becomes longer, and the stirring rod on the inner wall of the rotating sleeve stirs the fluid to prevent impurities from settling, thereby solving the problem that the fluid in the impurities is easy to adhere to the inner wall of the sleeve.

[0021] Example:

[0022] See also Figure 1 - Figure 5 The utility model provides a technical solution: an anti-blocking shell and tube heat exchanger, comprising an outer jacket 1, the inner wall of the outer jacket 1 is fixedly connected with an inlet pipe 1 2, an inlet pipe 2 3 is arranged outside the inlet pipe 1 2, an inner jacket 4 is fixedly connected to the bottom end of the inlet pipe 2 3, the outer surface of the inner jacket 4 is fixedly connected to the inner surface of the outer jacket 1, the inner surface of the outer jacket 1 is rotatably connected with a rotating sleeve 6, the inner and outer walls of the rotating sleeve 6 are rotatably connected with a sealing ring 5, the sealing ring 5 can prevent fluid from overflowing, the outer surface of the rotating sleeve 6 is fixedly connected with a swing mechanism 7, the inner wall of the rotating sleeve 6 is evenly distributed with stirring rods 8, the inner wall of the inner jacket 4 is fixedly connected with an outlet pipe 2 9, the outer The inner wall of the sleeve 1 is fixedly connected with an outlet pipe 10, and the inner wall of the outlet pipe 10 is slidably connected with an anti-blocking mechanism 11. Fluid 1 and fluid 2 flow out from the outlet pipe 10 and the outlet pipe 2 9 respectively through the anti-blocking mechanism 11. The operator can rotate the anti-blocking mechanism 11 at any time. The anti-blocking mechanism 11 includes a lifting pipe 12, and the top of the lifting pipe 12 is rotatably connected with a baffle rod 13. The outside of the baffle rod 13 is provided with a through groove 14, and the through groove 14 is opened in the wall of the lifting pipe 12. Rotating the lifting pipe 12 causes the baffle rod 13 to rotate to break up the possible accumulated sediment, and the sediment then flows out from the through groove 14 or around the top of the lifting pipe 12.

[0023] The bottom end of the lifting tube 12 is fixedly connected with a clamping plate 15, and the outer surface of the clamping plate 15 is slidably connected to the inner surface of the outlet pipe 10. The interior of the outlet pipe 2 9 is also provided with an anti-blocking mechanism 11. Before rotating the anti-blocking mechanism 11, the clamping plate 15 is pulled out from the outlet pipe 10 or the outlet pipe 2 9, and then the lifting tube 12 is rotated; the swing mechanism 7 includes a fixed rod 16, the outer surface of the fixed rod 16 is slidably connected with a first connecting belt 17, the outer surface of the first connecting belt 17 is fixedly connected with a rotating rod 18, the outer surface of the rotating rod 18 is threadedly connected with a first telescopic tube 20, and the end of the first telescopic tube 20 away from the first connecting belt 17 is fixedly connected with a motor 21. When the motor 21 works, the first telescopic tube 20 rotates. Since the front end of the first telescopic tube 20 is threadedly connected to the rotating rod 18, when the first telescopic tube 20 no longer moves on the rotating rod 18, the rotating rod 18 rotates with the first telescopic tube 20.

[0024] The outer surface of the first telescopic tube 20 is rotatably connected with a toothed belt 22, and the outer surface of the toothed belt 22 is rotatably connected with a second telescopic tube 23. The outer surface of the second telescopic tube 23 is threadedly connected with a rotating rod 24, and the outer surface of the rotating rod 24 is fixedly connected with a second connecting belt 25. The toothed belt 22 is meshed with both the first telescopic tube 20 and the second telescopic tube 23, so that the second telescopic tube 23 rotates with the first telescopic tube 20 and has the same direction. Since the thread on the rotating rod 24 is in opposite direction to the thread on the rotating rod 18, the second telescopic tube 23 is rotated to contract without driving the rotating rod 24 to rotate. The inner surface of the second connecting belt 25 is slidably connected with the outer surface of the fixed rod 16, and the outer surface of the rotating rod 18 is fixedly connected with a telescopic block 19, and the top of the telescopic block 19 is also fixedly connected with the outer surface of the rotating rod 24. When the rotating rod 18 rotates the rotating sleeve 6 between the outer sleeve 1 toward the direction of the first connecting belt 17 through the first connecting belt 17 and the fixed rod 16, the second connecting belt 25 is driven and the rotating rod 24 is pulled up, and the length of the telescopic block 19 becomes longer.

[0025] Working principle:

[0026] When in use, fluid 1 enters the outer sleeve 1 from the inlet pipe 1 2, and fluid 2 enters the inner sleeve 4 from the inlet pipe 2 3. When the two are exchanging heat, the motor 21 in the swing mechanism 7 works to rotate the first telescopic tube 20. The first telescopic tube 20 and the second telescopic tube 23 are connected by a toothed belt 22, and the toothed belt 22 is engaged with both the first telescopic tube 20 and the second telescopic tube 23. Then, the second telescopic tube 23 rotates with the first telescopic tube 20 and the direction is the same. Since the front end of the first telescopic tube 20 is threadedly connected to the rotating rod 18, when the first telescopic tube 20 no longer moves on the rotating rod 18, the rotating rod 18 rotates with the first telescopic tube 20. At this time, the rotating rod 18 The rotating sleeve 6 between the outer sleeves 1 is rotated toward the first connecting belt 17 through the first connecting belt 17 and the fixed rod 16. The sealing ring 5 arranged at the connection between the rotating sleeve 6 and the outer sleeve 1 can prevent the fluid from overflowing. At this time, the second connecting belt 25 is driven and the rotating rod 24 is pulled up, so that the length of the telescopic block 19 becomes longer. Since the thread on the rotating rod 24 is in opposite direction to the thread on the rotating rod 18, the rotating second telescopic tube 23 is contracted without driving the rotating rod 24 to rotate. The stirring rod 8 on the inner wall of the rotating sleeve 6 stirs the fluid to prevent impurities from settling. When the motor 21 controls the first telescopic tube 20 to reverse, the rotating sleeve 6 rotates toward the second connecting belt 25 in the same way as above.

[0027] Fluid 1 and fluid 2 flow out from outlet pipe 10 and outlet pipe 2 9 respectively through the anti-blocking mechanism 11. The operator can rotate the anti-blocking mechanism 11 at any time, first pull out the clamping plate 15 from outlet pipe 10 or outlet pipe 2 9, and then rotate the lifting pipe 12 to make the baffle rod 13 rotate to break up the possible accumulated sediment, and the sediment then flows out from the through groove 14 or around the top of the lifting pipe 12.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
