Description

Technical Field

[0001] The present invention relates to the technical field of evaporators, and in particular to an energy-saving heat exchange component of an evaporator for recovering waste mineral oil. Background Art

[0002] Waste mineral oil is extracted and refined from petroleum, coal, and oil shale. During the extraction, processing, and use processes, due to external factors, its original physical and chemical properties are changed, and it can no longer be used. If waste mineral oil is not properly treated, once a large amount of it enters the external environment, it will cause serious environmental pollution, damage the normal living environment of organisms, and have a physical effect of causing biological dysfunction. When the soil pores are relatively large, petroleum wastewater can also penetrate into the soil layer and pollute shallow groundwater. Most of the existing waste mineral oil treatment methods are to distill the waste mineral oil level by level through distillation, and then centrally treat the remaining solid waste residue.

[0003] In the prior art, the patent number is CN211739957U, and the name is an evaporator with efficient heat exchange, including: a refrigerant inlet, a tube box, heat transfer tubes, baffle plates, a refrigerant outlet, a shell, a heat medium inlet, a heat medium outlet, and a partition plate. The refrigerant inlet and the refrigerant outlet are respectively located on both sides of the tube box, the heat medium inlet and the heat medium outlet are respectively located on both sides of the shell, the tube box and the shell are connected and do not communicate with each other, the partition plate is located inside the tube box, the heat transfer tubes are located inside the shell and communicate with the tube box, and both ends of the baffle plate are respectively fixed on the shell and the heat transfer tubes; external fins are provided on the outer surface of the heat transfer tubes.

[0004] However, in the existing evaporator, fins are provided on the surface, and multiple groups of fins are stacked together. Since the distance between the fins is very close, it is difficult to remove the dust and impurities between the fins, which affects the heat dissipation effect of the fins. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy-saving heat exchange component of an evaporator for recovering waste mineral oil to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An energy-saving heat exchange component of an evaporator for recovering waste mineral oil, comprising:

[0007] A frame, a connecting frame is fixed on the surface of the frame, a tube bundle is arranged inside the frame, an extension block is fixed on the surface of the frame, a second moving rod is arranged inside the extension block, a first sleeved ring is arranged on the surface of the second moving rod, a vertical plate is fixed on the surface of the first sleeved ring, a second sleeved ring is arranged on the surface of the vertical plate, a screw rod is arranged inside the second sleeved ring, fins are arranged on the surface of the frame, first clamping grooves and second clamping grooves are formed on the surface of the fins, magnets are arranged on the surface of the first clamping grooves, and fixing rods are arranged inside the frame.

[0008] Preferably, a fixing plate is fixed on the surface of the frame. A support rod is fixed on the surface of the fixing plate. A cross bar is fixed on the surface of the support rod. A track rod is fixed on the surface of the support rod. A chute is formed on the surface of the track rod. An insertion rod is inserted into the chute and can move in the chute. An extension rod is fixed on the surface of the insertion rod. A first moving rod is inserted into the extension rod and can move inside the extension rod. A chute is fixed at one end of the first moving rod. The other end of the first moving rod is connected to a connecting plate. Both the chute and the connecting plate move along with the first moving rod.

[0009] Preferably, multiple groups of magnets are fixed on the surface of the connecting plate. The multiple groups of magnets are evenly distributed on the surface of the connecting plate. Extension blocks are fixed on the surfaces of the frame and the connecting frame. A slot is formed on the surface of the extension block. A second moving rod is inserted into the slot and can move inside the slot. An annular groove is formed on the surface of the second moving rod. A first sleeved ring is arranged outside the annular groove and is stuck in the annular groove. The second moving rod moves along with the first sleeved ring.

[0010] Preferably, a vertical plate is fixed on the surface of the first sleeved ring. A second sleeved ring is fixed at the middle position of the vertical plate. A screw rod is screwed on the surface of the frame. An annular groove is formed on the surface of the screw rod. The second sleeved ring is located in the annular groove on the surface of the screw rod and moves along with the screw rod, so that the first sleeved ring, the second moving rod and the vertical plate all move along with the screw rod.

[0011] Preferably, multiple groups of fins are provided. The multiple groups of fins are attached to the surface of the tube bundle. Two first card slots are formed on one side surface of the fin. Magnets are fixed on the inner walls of the first card slots. The end of the fixing rod is inserted into the slot and can move in the slot. Multiple groups of fins are arranged outside the fixing rod. Two second card slots are formed on the other side of the fin.

[0012] Preferably, a second holding ring and a first pushing ring are fixed on the surface of the second moving rod. The first pushing ring and the second holding ring are respectively located at both ends of the fixing rod. Both the second holding ring and the first pushing ring are located in the slot. And a limiting plate is fixed on the surface of the frame and is located at the end of the slot. When the fixing rod moves in the slot and reaches the end of the slot, the surface of the fixing rod abuts against the surface of the limiting plate.

[0013] Preferably, the second moving rod is inserted into the fixing rod and the fixing rod can move on the surface of the second moving rod. After the fixing rod moves, it abuts against the surfaces of the first pushing ring and the second holding ring. An adjusting slot is formed on the end surface of the fixing rod. A force-bearing rod is inserted into the adjusting slot and can move in the adjusting slot. After the second holding ring moves along with the second moving rod, the surface of the second holding ring abuts against the surface of the force-bearing rod, causing the force-bearing rod to move in the adjusting slot.

[0014] Preferably, a transverse groove is formed inside the fixed rod. An adjusting rod is arranged in the transverse groove. The end of the adjusting rod is connected to the end of the stress rod. The adjusting rod moves along with the stress rod. A holding block is fixed on the surface of the adjusting rod. There are multiple groups of holding blocks. The diameter of one side of the holding block is larger than that of the other side. A force - applying block is inserted into the surface of the fixed rod. There are multiple groups of force - applying blocks. The force - applying blocks can expand and contract on the surface of the fixed rod.

[0015] Preferably, after the holding block moves along with the adjusting rod, the surface of the holding block abuts against the surface of the force - applying block, causing the force - applying block to move on the surface of the fixed rod. Since the first card slot on the surface of the fin is stuck on the surface of the fixed rod, after the force - applying block on the surface of the fixed rod moves, it abuts against the surface of the first card slot, making the fin stable on the surface of the fixed rod.

[0016] Preferably, a spring is arranged on the surface of the adjusting rod. One end of the spring is connected to the inner wall of the transverse groove, and the other end is connected to the surface of the holding block. The spring has a pulling force on the holding block, causing the stress rod at the end of the adjusting rod to approach the surface of the second moving rod. When the adjusting rod moves, the spring is stretched.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When it is necessary to clean the dust and impurities on the surface of the fin in the present invention, by moving the second moving rod, the first pushing ring on the surface of the second moving rod abuts against the fixed plate, causing the fixed plate to drive the fin to move out from the surface of the tube bundle. The support rod is fixed by the fixed plate. By pushing the first moving rod through the sliding groove, the first moving rod moves inside the extension rod. After the first moving rod drives the connecting plate to move, the connecting plate abuts against the surface of the fin. The magnet on the surface of the connecting plate adsorbs on the surface of the fin. After the fin continues to move, the second card slot on the surface of the fin is stuck on the surface of the cross bar. After screwing the screw rod, the fixed plate is disengaged from the inside of the first card slot. Through the adsorption of the magnet and the limit of the cross bar stuck in the second card slot, the fin can move on the surface of the cross bar, and the distance between multiple groups of fins can be increased, facilitating the cleaning of the dust and impurities on the surface of the fin. And since the magnet on the surface of the connecting plate is composed of multiple strips, the contact area between the magnet and the fin is small, reducing the friction force and facilitating the movement of the fin on the surface of the magnet.

The second holding ring 28 and the first pushing ring 27 are both located in the slot 21. And a limiting plate 25 is fixed on the surface of the frame 1. The limiting plate 25 is located at the end of the slot 21.

The second moving rod 16 is inserted into the fixed rod 20. The fixed rod 20 can move on the surface of the second moving rod 16. After the fixed rod 20 moves, it will abut against the surfaces of the first pushing ring 27 and the second holding ring 28. An adjustment slot 30 is formed on the end surface of the fixed rod 20. A force-bearing rod 29 is inserted into the adjustment slot 30. The force-bearing rod 29 can move in the adjustment slot 30. After the second holding ring 28 moves along with the second moving rod 16, the surface of the second holding ring 28 abuts against the surface of the force-bearing rod 29, causing the force-bearing rod 29 to move in the adjustment slot 30. A transverse slot 34 is formed in the fixed rod 20. An adjustment rod 33 is arranged in the transverse slot 34. The end of the adjustment rod 33 is connected to the end of the force-bearing rod 29.

Multiple groups of force-applying blocks 26 are provided. The force-applying block 26 can expand and contract on the surface of the fixed rod 20. After the holding block 32 moves along with the adjustment rod 33, the surface of the holding block 32 abuts against the surface of the force-applying block 26, causing the force-applying block 26 to move on the surface of the fixed rod 20. Since the first card slot 19 on the surface of the fin 35 is stuck on the surface of the fixed rod 20, after the force-applying block 26 on the surface of the fixed rod 20 moves and abuts against the surface of the first card slot 19, the fin 35 is stabilized on the surface of the fixed rod 20.

When the adjustment rod 33 moves, the spring 31 is stretched.

[0035] A vertical plate 18 is fixedly arranged on the surface of the first set of setting rings 17, and a second set of setting rings 23 is fixedly arranged at the middle position of the vertical plate 18. A screw rod 24 is screwed on the surface of the frame 1. A ring groove is arranged on the surface of the screw rod 24. The second set of setting rings 23 is located in the ring groove on the surface of the screw rod 24. The second set of setting rings 23 moves along with the screw rod 24, so that the first set of setting rings 17, the second moving rod 16 and the vertical plate 18 all move along with the screw rod 24. The screw rod 24 drives the second moving rod 16 to move in the slot 21 through the second set of setting rings 23 and the first set of setting rings 17.

One end of the fin 35 abuts against the surface of the tube bundle 3, playing a role in heat dissipation. When it is necessary to clean the dust and impurities on the surface of the fin 35, the second moving rod 16 moves. The first pushing ring 27 on the surface of the second moving rod 16 abuts against the fixed rod 20, so that the fixed rod 20 drives the fin 35 to move out of the surface of the tube bundle 3. The support rod 5 is fixed through the fixing plate 4. The first moving rod 11 is pushed through the sliding groove 9, so that the first moving rod 11 moves inside the extension rod 10. After the first moving rod 11 drives the connecting plate 13 to move, the connecting plate 13 abuts against the surface of the fin 35. The magnet 14 on the surface of the connecting plate 13 adsorbs on the surface of the fin 35. After the fin 35 continues to move, the second clamping groove 22 on the surface of the fin 35 is stuck on the surface of the cross bar 6. After the screw 24 is screwed, the fixed rod 20 is separated from the inside of the first clamping groove 19. Through the adsorption of the magnet 14 and the limit of the cross bar 6 stuck in the second clamping groove 22, the fin 35 can move on the surface of the cross bar 6, and the distance between multiple fins 35 can be increased, which is convenient for cleaning the dust and impurities on the surface of the fin 35. And because the magnet 14 on the surface of the connecting plate 13 is composed of multiple strips, the contact area between the magnet 14 and the fin 35 is small, so that the friction force is reduced, which is convenient for the fin 35 to move on the surface of the magnet 14.
