Description

Technical Field

[0001] This utility model relates to the field of graphite heat exchanger technology, specifically a graphite heat exchanger with temperature compensation. Background Technology

[0002] Graphite heat exchangers are heat exchange devices made of impermeable graphite as the base material. Graphite heat exchangers are the most widely used and typical chemical unit equipment in graphite equipment. In the existing technology, when cleaning a graphite heat exchanger that is blocked, it is inconvenient to add the cleaning agent into the inside of the graphite heat exchanger, which makes the cleaning convenience less than ideal.

[0003] For example, patent publication number CN220454383U specifically describes a graphite heat exchanger, belonging to the technical field of graphite heat exchanger technology. Its key technical features include a graphite heat exchanger body, with a stabilizing mechanism externally positioned to move the body. The stabilizing mechanism is further supported by a support component to increase its stability. In use, the graphite heat exchanger body is placed on top of a semi-circular plate. The weight of the graphite heat exchanger body causes the support plate and guide rod to descend. As the support plate descends, the semi-circular plate... The outer wall of the circular plate contacts the outer wall of the arc-shaped plate, causing one end of the arc-shaped plate to rotate. This allows the arc-shaped plate to clamp the graphite heat exchanger body, preventing it from falling during movement. By setting up a support assembly, the stabilizing mechanism is prevented from moving when the graphite heat exchanger body is removed from its interior, thus facilitating the removal of the graphite heat exchanger body. However, this also presents a problem: when cleaning a clogged graphite heat exchanger, it is inconvenient to add cleaning agent inside, making the cleaning process less than ideal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a graphite heat exchanger with temperature compensation, which solves the problem that it is inconvenient to add cleaning agent to the inside of the graphite heat exchanger when cleaning it when it is clogged, making the cleaning process less convenient.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a graphite heat exchanger with temperature compensation, comprising a heat exchanger body, an end cap at one end of the heat exchanger body, a compensation mechanism on the end cap, and an automatic dosing mechanism at the bottom of the heat exchanger body.

[0006] The automatic dosing mechanism includes a base, inside which are two mixing chambers. Each mixing chamber has two storage chambers connected to one side. A first one-way valve is provided between the storage chambers and the mixing chambers. A piston plate is provided inside each mixing chamber. A piston rod is fixedly connected to the end of the piston plate. A connecting rod is rotatably connected to the end of the piston rod. Movable rods are rotatably connected to the ends of the two connecting rods. A rocker arm is rotatably connected to the movable rod. A driven wheel is rotatably connected to the end of the rocker arm. A driving wheel is provided on the top of the driven wheel. A belt is sleeved between the driving wheel and the driven wheel. A drive motor is fixedly connected to the end of the driving wheel. A drain pipe is provided on one side of the top of each of the two mixing chambers. A switch valve and a second one-way valve are provided on the drain pipe.

[0007] Preferably, the two mixing tanks are symmetrically arranged inside the base, and the two mixing tanks are connected to the inside of the heat exchanger body through a drain pipe, so that the cleaning liquid mixed inside the mixing tank can be sent into the inside of the heat exchanger body.

[0008] Preferably, the piston plate is slidably connected to the inner wall of the mixing chamber, and the side surface of the piston plate is provided with multiple sealing rings, which can increase the sealing effect between the piston plate and the inner wall of the mixing chamber.

[0009] Preferably, the top end of the rocker arm is rotatably connected to an eccentric part of one side surface of the driven wheel, and the bottom end of the rocker arm is rotatably connected to the movable rod through a bearing, so that when the driven wheel rotates, it can drive the movable rod to rise and fall through the rocker arm.

[0010] Preferably, the storage box is equipped with an addition tube, and the end of the addition tube is threaded with a tube cap, which allows for convenient addition of cleaning agent and water to the inside of the storage box, preventing insufficient cleaning agent and water.

[0011] Preferably, both the driving wheel and the driven wheel are rotatably connected to the inner wall of the base, and the output shaft of the drive motor is connected to the driven wheel via the driving wheel and a belt, so that the drive motor can drive the driven wheel to rotate.

[0012] Preferably, the compensation mechanism includes multiple guide rods, the ends of which are fixedly connected to the ends of the heat exchanger body. Each guide rod has an installation thread, and a pressure cap is threadedly connected to the guide rod via the installation thread. A compensation spring is provided at the bottom of the pressure cap, which can provide temperature compensation for the seal on the heat exchanger body and improve the sealing effect.

[0013] This invention provides a graphite heat exchanger with temperature compensation. Compared with the prior art, it has the following advantages:

[0014] 1. This temperature-compensated graphite heat exchanger, by opening the switch valve, drives the motor to move the piston plate. During the reciprocating movement of the piston plate, the piston plate pulls back to draw the cleaning agent and clean water inside the storage tank into the mixing tank. The piston plate pushes to mix the cleaning agent and clean water to form a cleaning liquid, which is then pushed into the drain pipe. This process is repeated continuously to send the cleaning liquid into the heat exchanger body, eliminating the need for manual addition and improving the convenience of cleaning.

[0015] 2. This temperature-compensated graphite heat exchanger uses a compensating spring fitted onto a guide rod, and then a pressure cap screwed onto the guide rod. The pressure cap presses the compensating spring, which in turn compensates for the temperature of the seal on the heat exchanger body, thus improving the sealing effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3This utility model provides a technical solution: a graphite heat exchanger with temperature compensation, including a heat exchanger body 1. The heat exchanger body 1 exchanges heat through the graphite tube wall, thereby achieving a good heat exchange effect. One end of the heat exchanger body 1 is provided with an end cap 3, and the end cap 3 is provided with a compensation mechanism 4. The bottom of the heat exchanger body 1 is provided with an automatic dosing mechanism 2. The cleaning agent can be fully mixed by the automatic dosing mechanism 2, and then the mixed cleaning solution is sent into the interior of the heat exchanger body 1 without manual addition, thus improving the convenience of cleaning.

[0023] The automatic dosing mechanism 2 includes a base 201, inside which are two mixing tanks 202, and attached... Figure 2The top cover of the mixing tank 202 is not shown, but it is for easy observation of the internal structure. Each mixing tank 202 has two storage tanks 203 connected to one side. The two storage tanks 203 are used to store cleaning agent and water respectively, facilitating mixing to create a cleaning solution. Each storage tank 203 is equipped with an addition pipe, the end of which is threaded with a cap, allowing for easy addition of cleaning agent and water to the storage tank 203, preventing insufficient cleaning agent and water. A first one-way valve 204 is provided between the storage tank 203 and the mixing tank 202. The first one-way valve 204 prevents water and cleaning agent from flowing back into the storage tank 203. 02 is equipped with a piston plate 205, which is slidably connected to the inner wall of the mixing chamber 202. Multiple sealing rings are provided on the side surface of the piston plate 205 to enhance the sealing effect between the piston plate 205 and the inner wall of the mixing chamber 202. A piston rod 209 is fixedly connected to the end of the piston plate 205, and a connecting rod 210 is rotatably connected to the end of the piston rod 209. Movable rods 211 are rotatably connected to the ends of the two connecting rods 210, and a rocker arm 212 is rotatably connected to the movable rod 211. A driven wheel 213 is rotatably connected to the end of the rocker arm 212, and the top of the rocker arm 212 is eccentric to one side surface of the driven wheel 213. The rocker arm 212 is rotatably connected to the movable rod 211 via a bearing at its bottom end, allowing the driven wheel 213 to rotate and drive the movable rod 211 to rise and fall via the rocker arm 212. A drive wheel 214 is located at the top of the driven wheel 213, and a belt 215 is sleeved between the drive wheel 214 and the driven wheel 213. A drive motor 216 is fixedly connected to the end of the drive wheel 214. Both the drive wheel 214 and the driven wheel 213 are rotatably connected to the inner wall of the base 201. The output shaft of the drive motor 216 is connected to the driven wheel 213 via the drive wheel 214 and the belt 215, enabling the drive motor 216 to drive the driven wheel 213. It can drive the driven wheel 213 to rotate. Each of the two mixing tanks 202 has a drain pipe 206 on one side of its top. The two mixing tanks 202 are symmetrically arranged inside the base 201. The two mixing tanks 202 are connected to the heat exchanger body 1 through the drain pipe 206, so that the cleaning liquid mixed inside the mixing tank 202 can be sent into the heat exchanger body 1. The drain pipe 206 is equipped with a switch valve 208 and a second check valve 207. The second check valve 207 can prevent the cleaning liquid inside the mixing tank 202 from flowing back from the drain pipe 206 into the mixing tank 202.

[0024] Please see Figure 1 and Figure 4The compensation mechanism 4 includes multiple guide rods 401, the ends of which are fixedly connected to the ends of the heat exchanger body 1. The guide rods 401 are provided with mounting threads 402, and a pressure cap 403 is threadedly connected to the guide rods 401 through the mounting threads 402. A compensation spring 404 is provided at the bottom of the pressure cap 403. The compensation spring 404 can be sleeved on the guide rods 401, and then the pressure cap 403 can be screwed on the guide rods 401. The pressure cap 403 presses the compensation spring 404, and the compensation spring 404 plays a temperature compensation role on the seal of the heat exchanger body 1, thereby improving the sealing effect.

[0025] During operation, opening the switch valve 208 activates the drive motor 216, which in turn drives the drive wheel 214 to rotate. The drive wheel 214 then drives the belt 215 to rotate, which in turn drives the driven wheel 213 to rotate. The driven wheel 213 then drives the rocker arm 212 to rotate, which in turn drives the movable rod 211 to move up and down continuously. The movable rod 211 then drives the connecting rod 210 to move, which in turn drives the piston rod 209 to reciprocate. The piston rod 209 then drives the piston plate 205 to move. During this reciprocating motion, the piston plate 205 pulls back, drawing the cleaning agent and water from the storage tank 203 into the mixing tank 202. The piston plate 205 then pushes the cleaning agent and water together to form a cleaning solution, which is then pushed into the drain pipe 206. This process is repeated continuously, continuously delivering the cleaning solution into the heat exchanger body 1. This eliminates the need for manual addition, improving the convenience of cleaning.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
