Description

Technical Field

[0001] The utility model relates to the technical field of fixed installation of heat exchangers, and specifically relates to a heat exchanger control device. Background Technique

[0002] The shell-and-tube heat exchanger, also known as the tubular heat exchanger, is a shell-and-tube heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. The shell-and-tube heat exchanger is composed of components such as a shell, a heat transfer tube bundle, a tube sheet, a baffle plate, and a tube box. The shell is mostly cylindrical, with a tube bundle installed inside. The two ends of the tube bundle are fixed on the tube sheet. For the two hot and cold fluids for heat exchange, one flows inside the tube, called the tube-side fluid; the other flows outside the tube, called the shell-side fluid. The existing shell-and-tube heat exchangers are generally fixed and installed by bolts. Although the installation is relatively firm, it is not convenient for subsequent disassembly, inspection, and maintenance. At the same time, the vibration generated during use after installation is likely to loosen the parts inside the shell-and-tube heat exchanger, thereby affecting the service life of the shell-and-tube heat exchanger. Therefore, we introduce a new heat exchanger control device.

[0003] A heat exchanger control device disclosed in the existing patent (publication number: CN220103847U) includes a bottom plate. Four buffer mechanisms are fixedly connected to the upper end of the bottom plate. Fixed blocks are fixedly connected to the upper ends of the four buffer mechanisms. Longitudinal two fixed blocks are fixedly connected with a limiting mechanism at the upper ends. A heat exchanger body is fixedly installed at the upper ends of the two limiting mechanisms. Hoisting rings are fixedly connected to the upper left side and the upper right side of the outer surface of the heat exchanger body. Connecting blocks are fixedly connected to the front part and the rear part of the left end and the front part and the rear part of the right end of the bottom plate. By setting the limiting mechanism, it is connected to the two hoisting rings on the heat exchanger through a hoisting device, the heat exchanger body is lifted and placed into the two limiting seats, the lower part of the heat exchanger body is closely attached to the cushion, and then the screw is rotated by turning the handle. The screw drives the clamping block through the movable sleeve to clamp and limit the heat exchanger body, so that the inner wall of the clamping block is closely attached to the outer surface of the heat exchanger body, so that the heat exchanger body is convenient for installation and subsequent disassembly, inspection, and maintenance.

[0004] However, the above technical solution still has certain defects. During the process of fixing the heat exchanger, the clamping block clamps the heat exchanger by rotating multiple groups of screws. This fixing method requires manual use of a rotating wrench to rotate multiple groups of screws, resulting in the fixing work of the heat exchanger being time-consuming. And it is not easy to control the clamping force of the clamping block on the heat exchanger manually, which is likely to cause the heat exchanger to be damaged by excessive clamping force. For this reason, a heat exchanger control device is proposed. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a heat exchanger control device to solve the technical problems raised in the above background.

[0006] To achieve the above object, the present utility model provides the following technical solution: A heat exchanger control device includes a fixing mechanism, and the inner wall of the fixing mechanism is sleeved with a heat exchanger main body;

[0007] The fixing mechanism includes two groups of brackets. The inner wall of each group of brackets is respectively fixedly connected with a group of air bags. The side wall of each group of brackets is respectively fixedly connected with a group of sleeves. The inner wall of each group of sleeves is respectively slidably sleeved with a group of pistons. The side wall of the piston is fixedly connected with a connecting rod extending outside the sleeve. An electric push rod is fixedly connected between the two connecting rods. The side wall of the sleeve is communicated with the air bag through a pipeline.

[0008] As a preferred technical solution of the heat exchanger control device of the present utility model, the bottom ends of the two groups of brackets are fixed with a buffer mechanism. The buffer mechanism includes a base. The two sides of the base are respectively fixedly connected with a group of guide rods. The outer walls of each group of guide rods are respectively slidably sleeved with two groups of sliders.

[0009] As a preferred technical solution of the heat exchanger control device of the present utility model, the top end of the slider is hinged with a top rod, and the two top rods on the same side are distributed in a V shape.

[0010] As a preferred technical solution of the heat exchanger control device of the present utility model, the top ends of multiple groups of top rods are hinged with a support plate, and the support plate is fixedly connected to the bottom ends of the two groups of brackets.

[0011] As a preferred technical solution of the heat exchanger control device of the present utility model, the bottom end of the support plate is fixedly connected with multiple groups of buffer springs, and the bottom ends of the buffer springs are fixedly connected to the top end of the base.

[0012] As a preferred technical solution of the heat exchanger control device of the present utility model, two groups of friction plates are fixedly connected to the positions on both sides of the top end of the base. The bottom end of each group of sliders is respectively slidably sleeved with a group of friction blocks, and the friction blocks are slidably attached to the top end of the friction plate.

[0015] 1. In the present utility model, by placing the heat exchanger main body inside two sets of brackets, two sets of airbags are sleeved on the outer wall of the heat exchanger main body. Then, an electric push rod is used to push a piston to inject air into the airbags, so that the airbags collide, and the heat exchanger main body is wrapped by the airbags, thereby achieving rapid fixation of the heat exchanger main body. Moreover, through the cooperation of the electric push rod and the airbags, overextrusion of the heat exchanger main body is avoided. To a certain extent, the airbags can play a role in shock absorption and buffering, further reducing the probability of damage to the heat exchanger.

[0016] 2. In the present utility model, when vibration occurs, the buffer spring is compressed, and the friction blocks slide between the friction plates, thereby buffering the vibration and consuming the impact force, making the buffering effect better. Also, it avoids the phenomenon of the buffer spring bouncing repeatedly after being vibrated, thus preventing the heat exchanger main body from shaking up and down continuously after being vibrated.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0026] The embodiments of the present utility model will be described below according to its overall structure.

[0027] A heat exchanger control device, as Figures 1 to 5 shown, includes a fixing mechanism 2, and a heat exchanger main body 3 is sleeved on the inner wall of the fixing mechanism 2;

[0028] The fixing mechanism 2 includes two groups of brackets 201. A group of air bags 202 are respectively fixedly connected to the inner walls of each group of brackets 201. A group of sleeves 203 are respectively fixedly connected to the side walls of each group of brackets 201. A group of pistons 204 are respectively slidably sleeved on the inner walls of each group of sleeves 203. A connecting rod 205 extending outside the sleeve 203 is fixedly connected to the side wall of the piston 204. An electric push rod 206 is fixedly connected between the two connecting rods 205. The side wall of the sleeve 203 is communicated with the air bag 202 through a pipeline.

[0029] By placing the heat exchanger main body 3 inside the two groups of brackets 201, and then extending the electric push rod 206, the two connecting rods 205 are pushed to both sides, so that the two connecting rods 205 push the two pistons 204 to slide inside the two groups of sleeves 203. During the sliding process of the piston 204, the air inside the sleeve 203 is pushed through the pipeline into the air bag 202, causing the air bag 202 to expand, so that the air bag 202 tightly sleeves on the outer wall of the heat exchanger main body 3, and the heat exchanger main body 3 is fixed inside the bracket 201. The extension stroke of the electric push rod 206 can be set in advance to avoid excessive expansion of the air bag 202, and the air bag 202 has a certain elasticity, so as to play a certain buffering effect.

[0030] Please refer specifically to Figure 1 , Figure 2 and Figure 3 , a buffer mechanism 1 is fixed at the bottom ends of the two groups of brackets 201. The buffer mechanism 1 includes a base 101. A group of guide rods 102 are respectively fixedly connected to both sides of the base 101. Two groups of sliders 103 are respectively slidably sleeved on the outer walls of each group of guide rods 102. A top rod 104 is hinged to the top end of the slider 103. The two top rods 104 on the same side are distributed in a V shape. A plurality of top rods 104 are hinged to a support plate 105. The support plate 105 is fixedly connected to the bottom ends of the two groups of brackets 201. A plurality of buffer springs 106 are fixedly connected to the bottom end of the support plate 105. The bottom ends of the buffer springs 106 are fixedly connected to the top end of the base 101. Two groups of friction plates 108 are fixedly connected to the positions near both sides of the top end of the base 101. A group of friction blocks 107 are respectively slidably sleeved on the bottom ends of each group of sliders 103. The friction blocks 107 slide and fit on the top ends of the friction plates 108. Two groups of spring pieces 109 are fixedly connected to the top end of the friction block 107. The top ends of the spring pieces 109 are fixedly connected to the side walls of the sliders 103.

[0031] When being vibrated again, the force received by the heat exchanger main body 3 during the vibration process is transmitted downward to the pallet 105, causing the pallet 105 to push multiple sets of ejector rods 104 and compress the buffer springs 106. During this process, the ejector rods 104 push the sliders 103 to slide on the outer wall of the guide rods 102, causing the sliders 103 to drive the friction blocks 107 to move, and making the friction blocks 107 slide and rub on the top of the friction plates 108. The buffering and consumption of the vibration received by the heat exchanger main body 3 are achieved by the resilience of the buffer springs 106 and the frictional force between the friction blocks 107 and the friction plates 108. Compared with the prior art where the vibration is buffered solely by the elastic deformation of the buffer springs 106, the phenomenon that the heat exchanger shakes up and down repeatedly after being vibrated is avoided, and the vibration is buffered more effectively.

[0032] During use, by placing the heat exchanger main body 3 inside two sets of brackets 201, the two sets of air bags 202 are sleeved on the outer wall of the heat exchanger main body 3. Then, the electric push rod 206 is used to push the piston 204 to inject air into the air bags 202, so that the air bags 202 collide, and the heat exchanger main body 3 is wrapped by the air bags 202, thus realizing the rapid fixation of the heat exchanger main body 3. Moreover, the cooperation of the electric push rod 206 and the air bags 202 avoids the over extrusion of the heat exchanger main body 3. To a certain extent, the air bags 202 can play a role in shock absorption and buffering, further reducing the probability of damage to the heat exchanger. The parts not involved in this device are the same as or can adopt the prior art to be realized.
