Description

Technical Field

[0001] This utility model relates to a heating plate structure for an evaporator, belonging to the field of evaporator technology. Background Technology

[0002] Plate evaporators, as a highly efficient heat exchange device, play an indispensable role in waste heat recovery systems. They can achieve heat transfer between different media through heat transfer plates, effectively recovering and utilizing the energy in waste heat.

[0003] After the evaporator has been put into use, due to changes in actual operating conditions, it is necessary to increase the number of evaporator heating plates. Usually, after the equipment is shut down, the entire evaporator is disassembled, and then new heating plates are added. Finally, the evaporator is reassembled. This method of disassembling and reassembling the entire evaporator increases the time spent on adding heating plates and has certain problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heating plate structure for an evaporator, which solves the problem of low efficiency in the conventional method of adding heating plates in the prior art.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a heating plate structure for an evaporator, comprising:

[0006] The base is horizontally positioned.

[0007] The main support rod is horizontally mounted on the base, and there are two main support rods arranged vertically.

[0008] Several heating plates are arranged side-by-side between two main support rods, extending along the direction of the main support rods.

[0009] A support structure is installed on the base to support the heating plate.

[0010] The first slide rail is connected to the support structure, and its extension direction is the same as that of the main support rod.

[0011] The second slide rail is located at the end of the first slide rail, and the first slide rail and the second slide rail are inserted into each other.

[0012] A sliding sleeve is fitted onto the second slide rail, and the end of the heating plate facing the base abuts against the sliding sleeve.

[0013] The first and second slide rails are connected to form a track structure, and the sliding sleeve can slide along the extension direction of the track structure. The track structure is respectively set on both sides of the extension direction of the main support rod.

[0014] By adopting the above technical solution, when the evaporator needs additional heating plates, the additional heating plates are first stacked on the sliding sleeve, and then the sliding sleeve is pushed to slide along the extension direction of the second slide rail and the first slide rail, so that multiple stacked heating plates move at the same time, achieving the purpose of one-time installation. Moreover, there is no need to disassemble the connecting bolts and support frame. Compared with the method of disassembling the entire evaporator and re-installing the heating plates, this can improve construction efficiency and reduce the time spent on evaporator modification.

[0015] The present invention is further configured such that the supporting structure includes:

[0016] The back plate is vertically fixed to the base, and the ends of the main support rod and the first slide rail are detachably and fixedly connected to the back plate.

[0017] A clamping plate is positioned between the two main support rods, and the clamping plate is located on the side of the heating plate away from the back plate.

[0018] Fastening bolts are installed on the back plate, extending through the clamping plate. Nuts are threaded onto the fastening bolts and located on the sides of the back plate and clamping plate that are furthest apart from each other.

[0019] The reinforcing rod is detachably and fixedly installed at the end of the main support rod away from the back plate.

[0020] The nuts, once tightened on the fastening bolts, cause the back plate and clamping plate to apply pressure to several heating plates.

[0021] By adopting the above technical solution, the main support rod and the first slide rail are installed on the back plate, so that the heating plate can be supported after being stacked on the main support rod and the first slide rail, thus improving the stability of the heating plate.

[0022] The present invention is further configured such that: a first pulley groove is provided on the side of the first slide rail and the second slide rail facing the heating plate; a plurality of first pulleys extending along the direction of the first slide rail are rotatably arranged in the first pulley groove; the outer curved surface of the first pulley extends to the outside of the first pulley groove and abuts against the inner side of the sliding sleeve; a second pulley groove is provided on the inner side of the sliding sleeve along the extension direction; a plurality of second pulleys are rotatably arranged in the second pulley groove; the outer curved surface of the second pulley extends to the inside of the sliding sleeve and abuts against the outer side of the track structure.

[0023] By adopting the above technical solution, since the sliding sleeve can slide on the first and second slide rails, and the sliding sleeve has sliding friction with the first and second slide rails, the sliding sleeve will wear out severely when subjected to load. By setting the rotating first and second pulleys, the friction between the sliding sleeve and the first and second slide rails can be changed to rolling friction, thereby reducing the wear of the sliding sleeve and improving its service life.

[0024] The present invention is further configured such that: an auxiliary support rod is hinged to the end of the second slide rail away from the first slide rail, and the end of the auxiliary support rod away from the second slide rail is detachably and fixedly connected to the base.

[0025] By adopting the above technical solution, after the second slide rail is connected to the first slide rail, the auxiliary support rod is flipped so that the movable end of the auxiliary support rod abuts against the base and is fixed with bolt fasteners, so that both ends of the track structure are fixed to the back plate and the base respectively, thus ensuring the stability of the track structure.

[0026] The present invention is further configured such that: a support plate is fixedly provided on both sides of the sliding sleeve in the extension direction; a threaded screw with its end extending to the outside of the base is rotatably provided on the base; a threaded sleeve is threaded on the threaded screw; and the threaded sleeve is fixedly connected to the support plate.

[0027] By adopting the above technical solution, when the sliding sleeve moves to the side of the second slide rail away from the first slide rail, the sliding sleeve part will be suspended. At this time, the suspended part of the sliding sleeve is supported by the connection of the threaded sleeve and the threaded screw, and the support plate is fixed to the sliding sleeve and the threaded sleeve respectively. At this time, when multiple heating plates are suspended on the sliding sleeve, the stability of the sliding sleeve can still be guaranteed, and the structural deformation of the sliding sleeve can be avoided, which further improves the reliability of the sliding sleeve.

[0028] The present invention is further configured such that an abutment plate is fixedly provided at the end of the sliding sleeve facing the heating plate and away from the first slide rail.

[0029] By adopting the above technical solution, the abutment plate can limit the end of the heating plate, preventing the sliding sleeve from slipping off the heating plate.

[0030] The beneficial effects of this utility model are as follows: When the evaporator needs additional heating plates, the clamping plate is first removed, and then the additional heating plates are stacked on the sliding sleeve. Then, the sliding sleeve is pushed to slide along the extension direction of the second slide rail and the first slide rail, so that multiple stacked heating plates move at the same time, achieving the purpose of one-time installation. Other support structures do not need to be disassembled. Compared with the traditional method of disassembling the entire evaporator and re-installing heating plates, this can further improve construction efficiency. Attached Figure Description

[0037] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0038] like Figure 1-3As shown, a heating plate structure for an evaporator includes a base 10, main support rods 14, heating plates 16, a first slide rail 20, a second slide rail 21, a sliding sleeve 22, and a support structure. The base 10 is placed horizontally on a mounting surface. The support structure is detachably and fixedly connected to the base 10. The main support rods 14 are horizontally arranged on the base 10, and two main support rods 14 are arranged vertically. Both main support rods 14 are fixed to the base 10 through the support structure. Several heating plates 16 are arranged between the two main support rods 14, and the heating plates 16 are arranged side by side along the extension direction of the main support rods 14. The heating plates 16 are provided with mating grooves for cooperating with the main support rods 14. The mating grooves and the main support rods 14 are inserted to form a limiting structure that restricts the rotation of the heating plates 16. At the same time, the support structure also supports the heating plates 16. The first slide rail 20 is connected to the support structure, and the extension direction of the first slide rail 20 is the same as the extension direction of the main support rods 14. The second slide rail 21 is located at the end of the first slide rail 20. A connector 32 is fixedly installed on the side of the first slide rail 20 facing the second slide rail 21. A connector groove 33 is opened at the connection end of the second slide rail 21 and the first slide rail 20. The connector 32 can be inserted into the connector groove 33 to form a connector structure, allowing the first slide rail 20 and the second slide rail 21 to be connected. A sliding sleeve 22 is fitted onto the second slide rail 21, and the end of the heating plate 16 facing the base 10 abuts against the sliding sleeve 22. After the first slide rail 20 and the second slide rail 21 are connected, a track structure is formed. The sliding sleeve 22 can slide along the extension direction of the track structure, that is, the sliding sleeve 22 can slide on the first slide rail 20 and the second slide rail 21. The track structure is respectively located on both sides of the extension direction of the main support rod 14.

[0039] like Figure 1 and Figure 4As shown, the support structure includes a back plate 11, fastening bolts 12, clamping plate 13, and reinforcing rod 15. The back plate 11 is vertically fixed to the base 10. The ends of the main support rod 14 and the first slide rail 20 are detachably and fixedly connected to the back plate 11. The end of the first slide rail 20 extends through the back plate 11 to the outside of the base 10. The end of the first slide rail 20 that extends through the back plate 11 is L-shaped and fixed to the back plate 11 with bolts. The main support rod 14 is directly fixed to the back plate 11 with bolts, and the main support rod 14 can also be welded to the back plate 11. The clamping plate 13 is disposed between the two main support rods 14, and the clamping plate 13 is located on the side of the heating plate 16 away from the back plate 11. The clamping plate 13 can slide on the main support rods 14. Fastening bolts 12 are mounted on the back plate 11, extending through the clamping plate 13. Nuts are threaded onto the fastening bolts 12, located on the sides of the back plate 11 and clamping plate 13 furthest from each other. The tightening direction of the nuts presses the clamping plate 13 towards the back plate 11. After the nuts are tightened on the fastening bolts 12, the back plate 11 and clamping plate 13 apply pressure to the heating plates 16. A reinforcing rod 15 is detachably fixed to the end of the main support rod 14 furthest from the back plate 11.

[0040] like Figure 4 and Figure 5 As shown, the first slide rail 20 has a first pulley groove 30 on the side facing the heating plate 16. Several first pulleys 31 extending along the direction of the first slide rail 20 are rotatably arranged within the first pulley groove 30. The outer curved surface of the first pulleys 31 extends to the outside of the first pulley groove 30 and abuts against the inner side of the sliding sleeve 22. The outer contour of the second slide rail 21 is the same as that of the first slide rail 20, and the side-by-side gap of the first pulleys 31 installed on the first slide rail 20 is the same as that on the second slide rail 21. A second pulley groove 34 is formed on the inner side of the sliding sleeve 22 along the extending direction. Several second pulleys 35 are rotatably arranged within the second pulley groove 34. The outer curved surface of the second pulleys 35 extends to the inside of the sliding sleeve 22 and abuts against the outer side of the track structure. An auxiliary support rod 27 is hinged to the end of the second slide rail 21 away from the first slide rail 20. The end of the auxiliary support rod 27 away from the second slide rail 21 is detachably and fixedly connected to the base 10.

[0041] like Figure 4As shown, support plates 24 are fixedly installed on both sides of the sliding sleeve 22 along its extension direction. The support plates 24 are fixed to the middle part of the sliding sleeve 22 and the end away from the first slide rail 20, respectively. A threaded screw 26 extending to the outside of the base 10 is rotatably installed on the base 10. A drive motor fixed to the base 10 can be optionally installed at one end of the threaded screw 26 extending outside the base 10. A threaded sleeve 25 is threadedly fitted on the threaded screw 26, and the threaded sleeve 25 is fixedly connected to the support plate 24. The drive motor drives the threaded screw 26 to rotate, and under the action of the threaded structure, the threaded sleeve 25 moves along the axial direction of the threaded screw 26, while driving the sliding sleeve 22 to move, thereby achieving the purpose of conveying the heating plate 16. An abutment plate 23 is fixedly installed at the end of the sliding sleeve 22 facing the heating plate 16 and away from the first slide rail 20. The abutment plate 23 can limit the end of the heating plate 16 to prevent the sliding sleeve 22 from slipping off the heating plate 16.

[0042] When the evaporator requires additional heating plates, such as Figure 2 As shown, first remove the reinforcing rod 15 and clamping plate 13, then stack the added heating plates 16 on the sliding sleeve 22. After the heating plates 16 are stacked, push the sliding sleeve 22 to slide along the extension direction of the second slide rail 21 and the first slide rail 20, so that the multiple stacked heating plates 16 move at the same time and are placed side by side with the old heating plates 16, achieving the purpose of one-time installation. Then, reinstall the reinforcing rod 15, clamping plate 13 and the nut for clamping the clamping plate 13 to clamp the 16. There is no need to disassemble the entire support structure. Compared with disassembling the evaporator as a whole and re-installing the heating plates, this can improve construction efficiency and reduce the time spent on evaporator modification.

[0043] By mounting the main support rod 14 and the first slide rail 20 on the back plate 11, the heating plate 16 can be supported after being stacked on the main support rod 14 and the first slide rail 20, thus improving the stability of the heating plate 16.

[0044] Since the sliding sleeve 22 can slide on the first slide rail 20 and the second slide rail 21, and the sliding sleeve 22 has sliding friction with the first slide rail 20 and the second slide rail 21, the sliding sleeve 22 will wear out severely when subjected to load. By setting the rotating first pulley 31 and the second pulley 35, the friction between the sliding sleeve 22 and the first slide rail 20 and the second slide rail 21 can be changed into rolling friction, thereby reducing the wear of the sliding sleeve 22 and improving its service life.

[0045] After the second slide rail 21 is connected to the first slide rail 20, the auxiliary support rod 27 is flipped so that the movable end of the auxiliary support rod 27 abuts against the base 10 and is fixed with bolt fasteners, so that both ends of the track structure are fixed to the back plate 11 and the base 10 respectively, ensuring the stability of the track structure.

[0046] When the sliding sleeve 22 moves to the side of the second slide rail 21 away from the first slide rail 20, part of the sliding sleeve 22 will be suspended. At this time, the suspended part of the sliding sleeve 22 is supported by the connection of the threaded sleeve 25 and the threaded screw 26, and the fixing of the support plate 24 to the sliding sleeve 22 and the threaded sleeve 25 respectively. At this time, when multiple heating plates 16 are suspended on the sliding sleeve 22, the stability of the sliding sleeve 22 can still be guaranteed, and the structural deformation of the sliding sleeve 22 can be avoided, which further improves the reliability of the sliding of the sliding sleeve 22.

Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
