Description

Technical Field

[0001] The utility model belongs to the technical field related to heat exchangers, and particularly relates to a heat exchanger partition processing device. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers can be used as heaters, coolers, condensers, evaporators, reboilers, etc., and are widely used. The structure of a heat exchanger is not complicated. It is often used to heat low-temperature fluids or cool high-temperature fluids, to vaporize liquids into steam or to condense steam into liquids. A heat exchanger can be a unit device, such as a heater, cooler, and condenser. Conventional heat exchangers usually require a variety of partitions, such as partitions for auxiliary heat exchange pipes, or partitions installed at the ends of heat exchangers. As for square partitions, they have the following disadvantages in actual processing:

[0003] Usually, in the processing of heat exchanger baffles, the baffles are first cut into the required size. The baffles in this state cannot be used directly. Usually, the burrs on the corners need to be polished clean before they can be put into use. However, usually, there are burrs not only on the cut side, but also on the edges of the upper and lower surfaces. When dealing with such burrs, it is usually impossible to complete the processing in one go, which increases the processing time and the processing efficiency is insufficient.

[0004] Secondly, the thickness of the partitions at different positions is different. If it needs to be processed in one go, it is necessary to adapt it to the partitions of different thicknesses for deburring.

[0005] Finally, deburring is usually done by grinding, which usually produces sparks and flying chips, which can easily affect the surrounding environment. Utility Model Content

[0006] The purpose of the utility model is to provide a heat exchanger partition processing device, which solves the problems of not being able to remove all burrs on the edge of the partition at one time, not being able to adapt to deburring processing on partitions of different thicknesses, and sparks and waste chips generated during grinding processing splashing and affecting the surrounding environment by arranging a rotating shaft, a grinding roller, an upper grinding disc, a lower grinding disc, a motor, a grinding assembly, and a threaded section.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] A grinding roller is fixed on the outer periphery of the rotating shaft, a lower grinding disc is fixed on the outer periphery of the grinding roller, a threaded section is also arranged on the outer periphery of the rotating shaft above the grinding roller, and a grinding assembly is screwed onto the threaded section.

[0010] Furthermore, legs are fixed at four corners of the bottom of the workbench, and the area of ​​the workbench is larger than the area of ​​the partition.

[0011] Furthermore, the grinding assembly includes a threaded ring and an upper grinding disc, the threaded ring is threadedly connected to the threaded section, the upper grinding disc is located below the threaded ring and is sleeved on the outside of the grinding roller, and connecting rods distributed in a ring array are fixed between the upper grinding disc and the threaded ring.

[0012] Furthermore, the upper grinding disc is in an inverted truncated cone structure, the lower grinding disc is in a truncated cone structure, and the upper grinding disc is located above the lower grinding disc, and the upper grinding disc and the lower grinding disc have the same size and are symmetrically distributed.

[0013] Furthermore, the outer peripheral surface of the grinding roller also contacts the side edge of the partition, the outer curved surface of the upper grinding disc contacts the edge of the upper surface of the partition, and the outer curved surface of the lower grinding disc contacts the edge of the lower surface of the partition.

[0014] Furthermore, a collecting hopper is fixed to one side of the vertical plate, and an end of the collecting hopper contacts the side surface of the partition plate.

[0016] Furthermore, a motor is fixed to the upper end of the horizontal plate located above, and the output shaft of the motor is fixedly connected to the upper end of the rotating shaft.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that all burrs on the edge of the partition cannot be removed at one time by arranging a rotating shaft, a grinding roller, an upper grinding disc, a lower grinding disc and a motor; the motor is used to drive the rotating shaft to rotate, and the outer periphery of the grinding roller contacts the partition, and the lower grinding disc and the upper grinding disc also rotate accordingly, the grinding roller grinds and removes burrs on the side of the partition, and the upper grinding disc rotates to grind the edge of the upper surface of the partition, and the lower grinding disc grinds the edge of the lower surface of the partition, and then the mounting frame is controlled to drive the rotating shaft, grinding roller and other components to move along the edge of the partition, so that the deburring process can be completed at one time.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1-7 As shown, the utility model is a heat exchanger baffle processing device, including a workbench 1, a mounting frame 2, a collecting hopper 3, a motor 4 and a rotating shaft 5. A support table 102 is fixed on the upper surface of the workbench 1, and a baffle is placed on the support table 102. A mounting frame 2 is also placed on the workbench 1 on one side of the support table 102. The mounting frame 2 includes two horizontal plates 201 and a vertical plate 202 fixed between the two horizontal plates 201, and bearings 2011 are fixed on the opposite surfaces of the two horizontal plates 201. The rotating shaft 5 is connected to the two bearings 211 for common rotation.

[0033] The workbench 1 supports the partition through the support table 102, and the mounting frame 2 is placed on the workbench 1 to assist in deburring the partition. The mounting frame 2 is composed of a horizontal plate 201 and a vertical plate 202. The rotatable shaft 5 is installed between the two horizontal plates 201 with a bearing 2011. The outer ring of the bearing 2011 is fixed to the horizontal plate 201, and the inner ring of the bearing 2011 is fixed to the shaft 5.

[0034] A grinding roller 501 is fixed to the outer periphery of the rotating shaft 5, a lower grinding disc 503 is fixed to the outer periphery of the grinding roller 501, a threaded section 504 is further provided on the outer periphery of the rotating shaft 5 above the grinding roller 501, and a grinding assembly 502 is screwed onto the threaded section 504;

[0035] The rotation of the rotating shaft 5 can drive the rotation of its external grinding roller 501 to grind and remove burrs on the side of the partition. At the same time, the upper grinding disc 5022 and the lower grinding disc 503 also rotate accordingly to grind the edges of the upper and lower surfaces of the partition respectively, thereby removing burrs.

[0036] The four corners of the bottom of the workbench 1 are fixed with legs 101, and the area of ​​the workbench 1 is larger than the area of ​​the partition; the legs 101 are used to support the workbench 1 so that it has a certain height. The area of ​​the workbench 1 must be larger than the area of ​​the partition because an auxiliary support mounting frame 2 is required to make it more labor-saving during operation. The top of the lower grinding disc 503 is flush with the bottom surface of the partition.

[0037] The grinding assembly 502 includes a threaded ring 5021 and an upper grinding disc 5022. The threaded ring 5021 is threadedly connected to the threaded section 504. The upper grinding disc 5022 is located below the threaded ring 5021 and sleeved outside the grinding roller 501. Connecting rods 5023 distributed in a ring array are fixed between the upper grinding disc 5022 and the threaded ring 5021.

[0038] In the grinding assembly 502, the threaded ring 5021 is connected to the upper grinding disc 5022 through a connecting rod 5023 to form a whole. When the threaded ring 5021 rotates and rises and falls on the threaded section 504, it will drive the upper grinding disc 5022 to rise and fall, thereby approaching or moving away from the lower grinding disc 503, so that it can be used for partitions of different thicknesses.

[0039] The upper grinding disc 5022 is an inverted truncated cone structure, the lower grinding disc 503 is a truncated cone structure, and the upper grinding disc 5022 is located above the lower grinding disc 503. The upper grinding disc 5022 and the lower grinding disc 503 are of the same size and are symmetrically distributed; the unique truncated cone structure design enables it to perform good grinding and deburring treatment on the edges of the upper and lower surfaces of the partition.

[0040] The outer peripheral surface of the grinding roller 501 also contacts the side edge of the partition, the outer curved surface of the upper grinding disc 5022 contacts the edge of the upper surface of the partition, and the outer curved surface of the lower grinding disc 503 contacts the edge of the lower surface of the partition;

[0041] Thus, the side surface and the edges of the upper and lower surfaces of the partition can be polished at one time, and the upper polishing disc 5022, the lower polishing disc 503 and the polishing roller 501 can be moved along the side of the partition.

[0042] A collecting hopper 3 is also fixed on one side of the vertical plate 202, and the end of the collecting hopper 3 contacts the side of the partition; the sparks and waste chips generated during grinding will splash in one direction, and the collecting hopper 3 only needs to be set in this direction, and the sparks and waste chips splashed by grinding will enter the collecting hopper 3 to avoid affecting the surrounding environment.

[0043] A handle 203 is fixed to a side of the vertical plate 202 away from the rotating shaft 5; the handle 203 is used to control the movement of the mounting frame 2, thereby driving the structure mounted thereon to move.

[0044] A motor 4 is fixed to the upper end of the horizontal plate 201 located at the top, and the output shaft of the motor 4 is fixedly connected to the upper end of the rotating shaft 5; the motor 4 can drive the rotating shaft 5 to rotate when it is working.

[0045] The specific working principle of the utility model is as follows: the partition is supported by the support table 102 on the workbench 1, and the threaded ring 5021 in the grinding assembly 502 is rotated to make it rise and fall on the threaded section 504 of the rotating shaft 5, thereby changing the distance between the upper grinding disc 5022 and the lower grinding disc 503, and the distance between the two corresponds to the thickness of the partition. The distance is changed to adapt to the thickness of the partition. At this time, the outer curved surface of the upper grinding disc 5022 contacts the edge of the upper surface of the partition, the outer curved surface of the lower grinding disc 503 contacts the edge of the lower surface of the partition, and the outer peripheral surface of the grinding roller 501 contacts the side of the partition; then the motor 4 works to drive the rotating shaft 5 rotates, and the rotation of the rotating shaft 5 can drive the rotation of its external grinding roller 501 to grind and remove burrs on the side of the partition. At the same time, the upper grinding disc 5022 and the lower grinding disc 503 also rotate accordingly to grind the edges of the upper and lower surfaces of the partition respectively, so as to remove burrs. Then, the handle 203 is held to control the mounting frame 2 to drive the rotating shaft 5, the grinding roller 501 and other components to move along the edge of the partition, so that the deburring process can be completed in one time. The sparks and waste chips generated during grinding will splash in one direction. A collecting hopper 3 is set in this direction, and the sparks and waste chips splashed by grinding enter the collecting hopper 3.

[0046] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
