Description

Technical Field

[0001] The utility model relates to an evaporator, in particular to a middle partition connecting device of an evaporator. Background Art

[0002] During the evaporator's heating process, a partition is installed to divide the space within the shell into two parts to improve heat exchange efficiency. The design of this partition plays a crucial role. Due to the large diameter and numerous internal components of the evaporator, it is usually not possible to transport it as a whole. Therefore, a large amount of welding and splicing work must be completed on-site. How to complete this work with the least amount of effort on-site becomes a key issue.

[0003] Problems:

[0004] 1. After the partitions are pressed and formed, it is difficult to ensure that the partitions are fully aligned due to the influence of the mold and the manufacturing process;

[0005] 2. Out-of-roundness in large-diameter equipment (when steel plates are rolled into cylinders, the theoretical roundness cannot be guaranteed due to welding deformation and other factors, but "out-of-roundness" is allowed within a certain range) results in gaps at the interface between the partitions and the cylinder. To compensate for these gaps, the positions of the different layers of partitions must be moved, causing the partitions to become misaligned. Utility Model Content

[0006] In order to solve the defects of the above-mentioned prior art, the utility model provides an evaporator middle partition connecting device, which can partially stagger the partition blocks with the help of horizontal connecting plates and effectively adjust the gap between the partition and the equipment.

[0007] To achieve the above technical objectives, the present invention adopts the following technical solutions: an evaporator intermediate partition connecting device, comprising a connecting plate and an auxiliary component, wherein the connecting plate is used to be welded between two adjacent intermediate partitions to eliminate the misalignment of the two adjacent intermediate partitions, and the auxiliary component is provided with two clamping claw structures for clamping the two adjacent intermediate partitions for pre-positioning;

[0008] The auxiliary component also includes a chain and two adjusting parts, which are respectively connected to the two clamping structures. The two adjusting parts are both provided with universal balls. The ends of the chain are connected to the universal balls, so that the two clamping structures can be clamped at different positions of the connecting plate, so that the connecting plate can be pre-positioned on the middle partition.

[0009] The clamping structure includes a first clamping plate, a second clamping plate, and a connecting bolt, the nut end of the connecting bolt is fixed to the second clamping plate, the stud is threadedly connected to the first clamping plate and fastened with a nut; positioning cylinders are respectively fixed on the opposite surfaces of the first clamping plate and the second clamping plate, and a number of cylindrical blind holes are opened on both side surfaces of the connecting plate, and the two positioning cylinders can be positioned in the two opposite cylindrical blind holes so that the clamping structure clamps the connecting plate.

[0010] The adjusting member includes an adjusting stud and an adjusting sleeve. The adjusting stud is fixed to the first clamping plate. The adjusting sleeve is threadedly connected to the adjusting stud. When the adjusting sleeve is rotated, the total length of the adjusting member can be adjusted.

[0011] A universal ball base is fixed on the outer end surface of the adjusting sleeve. The universal ball is arranged in the universal ball base, and the universal ball is fixedly connected to the chain.

[0012] In summary, the present invention has achieved the following technical effects:

[0013] The utility model adopts the method of adding a transverse connecting plate, which can accept a certain amount of misalignment of the upper and lower layers of partitions in each horizontal direction and ensure that they fit the "out-of-round" cylinder wall;

[0014] The utility model solves the problems of deformation caused by the division of large partitions into blocks and the inability to align during assembly.

[0015] The utility model reduces a large amount of correction and alignment work at the equipment installation site, and allows a certain amount of "misalignment" between the upper and lower partitions in various directions in the horizontal direction to compensate for the influence caused by the out-of-roundness of the cylinder.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0028] Example:

[0029] Figure 1 This is a schematic diagram of the middle partition of the evaporator. Figure 2 This is a schematic diagram of the effect conversion. Figure 3 This is a schematic diagram of the state where multiple intermediate partitions are connected using connecting plates. Figure 4 The present invention is a schematic diagram of an evaporator intermediate partition connection device, comprising a connecting plate 2 and an auxiliary component 3. The connecting plate 2 is used to be welded between two adjacent intermediate partitions 1 to eliminate the misalignment of the two adjacent intermediate partitions 1. The auxiliary component 3 is provided with two clamping structures for clamping the two adjacent connecting plates 2 for pre-positioning.

[0030] like Figure 3 As shown, when two adjacent intermediate partitions are butt-welded, the out-of-roundness of the evaporator cylinder and the errors between the two adjacent intermediate partitions can cause misalignment between them. Therefore, the provision of a connecting plate in the present invention eliminates this misalignment and eliminates gaps, reducing the extensive correction and alignment workload at the equipment installation site. This allows for a certain amount of horizontal misalignment between the upper and lower partitions to compensate for the out-of-roundness of the cylinder. The width of the connecting plate is greater than that of the partition, allowing for the partitions to move left and right, forward and backward, and rotate in plane.

[0031] like Figure 4 As shown, the auxiliary component 3 also includes a chain 310 and two adjusting members, and the two adjusting members are respectively connected to the two clamping structures. The two adjusting members are both provided with a universal ball 309, and the end of the chain 310 is connected to the universal ball 309, so that the two clamping structures can be clamped at different positions of the connecting plate 2, so that the connecting plate 2 is pre-positioned on the middle partition 1.

[0032] The clamping structure includes a first clamping plate 301, a second clamping plate 302, and a connecting bolt 304. The nut end of the connecting bolt 304 is fixed to the second clamping plate 302, and the stud is threadedly connected to the first clamping plate 301 and fastened with a nut 305; the opposite surfaces of the first clamping plate 301 and the second clamping plate 302 are respectively fixed with positioning cylinders 303, and a number of cylindrical blind holes are opened on both side surfaces of the connecting plate 2. The two positioning cylinders 303 can be positioned in the two opposite cylindrical blind holes, so that the clamping structure clamps the connecting plate 2.

[0033] The clamping is kept stable in the form of positioning cylinder 303 and cylindrical blind hole. The two clamps are clamped on the connecting plate 2 and the connecting bolt 304 is tightened. Under the action of positioning cylinder 303 and cylindrical blind hole, the clamp will not fall off by itself, with good safety performance and easy use.

[0034] The adjusting member includes an adjusting screw 306 and an adjusting sleeve 307. The adjusting screw 306 is fixed to the first clamping plate 301, and the adjusting sleeve 307 is threadedly connected to the adjusting screw 306. When the adjusting sleeve 307 is rotated, the total length of the adjusting member can be adjusted. A universal ball base 308 is fixed to the outer end surface of the adjusting sleeve 307. The universal ball 309 is disposed within the universal ball base 308 and is fixedly connected to the chain 310.

[0035] The chain is a flexible component that can be pulled in any direction and is easy to use.

[0036] The cylindrical blind holes of the connecting plate 2 of the present invention are aligned in pairs on the front and back sides, with a total of two rows. The number of rows is determined by the size of the waveform of the middle partition. Due to the misalignment of the two adjacent middle partitions, some of the cylindrical blind holes may be pressed by the middle partition. At the same time, the cylindrical blind holes are blind holes, and even if they are pressed, there will be no gaps. In this case, the pressed cylindrical blind holes cannot be used. Therefore, the total length is lengthened or shortened using an adjusting member, which allows one of the clamping claw structures to be clamped in the cylindrical blind hole at the remaining position, successfully pre-positioning the connecting plate. The utility model is provided with a universal ball, which allows the two clamping claw structures to change direction and angle at will, and with the cylindrical clamping, the clamping claw structure can be rotated to change position.

[0037] Working principle:

[0038] Make the partition in pieces;

[0039] Figure 1 The middle partition is a flat, corrugated three-dimensional shape. Figure 2 The left side is a schematic diagram showing that the original structure must maintain precise alignment, and the right side is a schematic diagram after adding the connecting plate of the present invention, and the right side shows an ideal state.

[0040] When two adjacent middle partitions have misaligned sides, first weld the bottom and one side of one middle partition to the bottom and side of the evaporator cylinder, then weld another middle partition to one side of the first middle partition until the bottom row is welded.

[0041] Take multiple connecting plates 2, weld the middle position of one side to the upper side of the first row of partitions, and weld the multiple connecting plates 2 to each other;

[0042] Take a connecting plate 2 and place it on the upper edge of the second row of partitions, ensuring that the side edges are aligned with the evaporator cylinder. Use at least three auxiliary components 3 to pre-position the connecting plate with the connecting plate in the lower row on both sides. Position the clamping structure in the cylindrical blind hole corresponding to the corrugated groove of the partition. If the cylindrical blind hole corresponding to the other connecting plate is pressed by the partition, loosen the adjustment sleeve, position the clamping structure in the cylindrical blind hole next to it, and tighten the adjustment sleeve. Once at least three auxiliary components 3 are installed, the pre-positioning of the connecting plate is complete.

[0043] Take the middle partition and place it on the connecting plate in the second row. After adjusting the position, you can move it left and right, front and back, or rotate it in a plane. Align the side edges of the connecting plate and the middle partition with the evaporator cylinder. Then weld the connecting plate, the first row of partitions, and the second row of partitions. Complete the welding of the second row in sequence. When welding the last partition in the second row, you can butt one side of the partition with the previous partition. Then, slightly rotate the partition with the butted edge as the axis so that the other side of the partition is butted with the inner wall of the evaporator cylinder. Complete the welding. Remove the auxiliary components.

[0044] Weld the remaining partitions in sequence.

[0045] Figure 5 This is a schematic diagram of the middle partition moving forward and backward. At this time, the waveforms of the two connected partitions are no longer aligned, but there is a connecting plate. The upper partition can move forward and backward at the position of the connecting plate to connect with the left and right partitions or the inner wall of the cylinder;

[0046] Figure 6 This is a schematic diagram of the middle partition moving left and right. At this time, the waveforms of the two connected partitions are no longer aligned, but there is a connecting plate. The upper partition can move forward and backward at the position of the connecting plate to connect with the left and right partitions or the inner wall of the cylinder;

[0047] At the same time, the partition can also dock one side with the previous partition, and then rotate with the docking side as the axis so that the other side can dock with the rear partition or the inner wall of the cylinder to ensure that there is no gap.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
