Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a partition plate structure of a heat exchanger. Background Art

[0002] The shell and tube heat exchanger is a partition-type heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. In order to slow down the flow rate of the heat exchange fluid in the heat exchanger, a partition plate structure is often set in the heat exchanger to increase the flow of the fluid. The partition plate divides the interior of the heat exchanger into multiple independent flow channels to ensure that different working media flow in their respective channels and prevent the two media from mixing.

[0003] However, it still has the following disadvantages in actual use:

[0004] A partition plate structure of a heat exchanger with a publication number of CN220583178U is retrieved, comprising a flow partition, a rotation area and a flow port are provided at the bottom of the flow partition, and a flow member that rotates under the action of a fluid is arranged in the rotation area; the utility model arranges a transmission member that rotates synchronously under the transmission of the flow member between two first brackets, and two second brackets are provided with a plurality of evenly distributed flow-breaking members and a guide member that cooperates with the transmission member to drive the flow-breaking members to reciprocate, the fluid acts on the flow member in the rotation area through the flow port, drives the flow member to rotate, drives the transmission member to rotate under the transmission of the flow member, and drives the flow-breaking member to reciprocate under the cooperation of the guide member and the transmission member, thereby changing the flow-breaking position of the flow-breaking member, so that the fluid flows at multiple angles along the direction of movement, which is beneficial to improving the heat exchange efficiency.

[0005] However, when the above device is used, dirt or sediment may accumulate in the paths between the partitions, affecting the heat exchange efficiency of the heat exchanger. It is necessary to regularly clean the heat exchanger to remove the accumulation. The existing cleaning method involves manually washing the partitions, which requires disassembling the heat exchanger, which is troublesome. Utility Model Content

The existing cleaning method involves manually washing the partition plates, which requires disassembling the heat exchanger, which is rather troublesome.

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

[0008] The utility model is a partition plate structure of a heat exchanger, comprising:

[0009] A main body mechanism, the main body mechanism comprising a partition plate;

[0010] The telescopic mechanism includes a rotating frame rotatably connected to the outer wall of one side of the output end of the partition plate, the inner wall of the rotating frame is provided with a mounting groove, the inner wall of the mounting groove is fixedly connected with a fixed block equidistantly around the circumference, the inner wall of the mounting groove is movably connected with an annular spring, the annular spring passes through the fixed block, and the inner wall of the fixed block is provided with a corresponding groove.

[0011] Furthermore, a pipe box is fixed to the outer wall of the partition plate with screws;

[0012] Furthermore, the outer wall of the annular spring is movably connected with a connecting rod between two adjacent fixed blocks, and the outer wall of the connecting rod is fixedly connected with a cleaning rack, and the cleaning rack is in contact with the outer wall of the partition plate;

[0013] Furthermore, it also includes a rotating mechanism, the rotating mechanism includes a motor fixedly connected to the outer wall of the pipe box, and the output end of the motor passes through one side of the pipe box and is fixedly connected to a screw rod;

[0014] Furthermore, the outer wall of the screw rod is rotatably connected to an engagement sleeve, and the outer wall of the circumference of the end of the engagement sleeve is fixedly connected to an extrusion frame;

[0015] Furthermore, it also includes a limiting mechanism, the limiting mechanism includes a connecting spring symmetrically fixedly connected to the circumferential outer wall of the engagement sleeve on one side close to the extrusion frame, the end of the connecting spring is fixedly connected to a limiting block, and the limiting block coincides with the corresponding groove;

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The utility model regularly turns on the motor to drive the screw rod to rotate, and the screw rod drives the engagement sleeve to rotate with the screw rod and move linearly along the screw rod. The engagement sleeve moves linearly to approach the rotating frame, and the engagement sleeve drives the extrusion frame to contact the connecting rod in a relaxed state, and pushes the connecting rod outward and stretches the annular spring. The connecting rod drives the cleaning frame to move outward to expand the cleaning range. The rotation of the engagement sleeve drives the rotating frame to rotate, and the rotating frame drives the expanded cleaning frame to rotate to clean the partition plate, thereby reducing the cleaning steps and saving time and effort.

[0018] 2. Based on the first beneficial effect, when the engaging sleeve drives the extrusion frame to push the connecting rod, the limit block that rotates with the engaging sleeve contacts the fixed block, and the rotating limit block is stuck in the corresponding grooves of the two symmetrical fixed blocks. The limit block is rotated clockwise so that it is always stuck in the corresponding groove, so that the rotation of the limit block drives the fixed block to rotate, thereby realizing the rotation of the rotating frame. When stopping cleaning, the limit block is rotated in the opposite direction to move out of the corresponding groove, so that the limit block is separated from the fixed block, and the annular spring of the rotating frame stops rebounding to return the connecting rod to its position, thereby ensuring the normal circulation of the partition plate.

[0035] The annular spring 205 is supported by the rotating frame 201, one end of the annular spring 205 is fixed by the fixing block 202, and the connecting rod 206 is returned to its original position by the rebound of the annular spring 205;

[0036] The outer wall of the annular spring 205 is located between two adjacent fixed blocks 202 and is movably connected with a connecting rod 206. The outer wall of the connecting rod 206 is fixedly connected with a cleaning frame 207. The cleaning frame 207 is in contact with the outer wall of the partition plate 102.

[0037] The cleaning frame 207 is driven to move by the connecting rod 206 to expand the cleaning range;

[0038] The rotating mechanism 3 includes a motor 301 fixedly connected to the outer wall of the pipe box 101, and an output end of the motor 301 passes through one side of the pipe box 101 and is fixedly connected to a screw rod 302;

[0039] The motor 301 provides power to the screw rod 302;

[0040] The outer wall of the screw rod 302 is rotatably connected to a meshing sleeve 303, and the outer wall of the circumference of the end of the meshing sleeve 303 is fixedly connected to an extrusion frame 304;

[0041] The screw rod 302 drives the engagement sleeve 303 to rotate and move linearly, the engagement sleeve 303 drives the extrusion frame 304 to move, and the extrusion frame 304 pushes the connecting rod 206;

[0042] Working principle: The motor 301 is turned on regularly to drive the screw rod 302 to rotate. The screw rod 302 drives the engagement sleeve 303 to rotate with the screw rod 302 and move linearly along the screw rod 302.

[0043] This step reduces the cleaning steps, saving time and effort.

[0044] See also Figure 1-4 As shown, this embodiment is based on the above embodiment 1 and also includes:

The limit block 402 is rotated clockwise to always be inserted into the corresponding grooves 203, so that the limit block 402 rotates and drives the fixed block 202 to rotate, thereby rotating the rotating frame 201. When the cleaning stops, the limit block 402 is rotated in the opposite direction to move out of the corresponding groove 203, so that the limit block 402 is separated from the fixed block 202, and the rotating frame 201 stops the annular spring 205 to rebound and return the connecting rod 206 to its original position;
