Description

Technical Field

[0001] This utility model relates to the field of graphite heat exchanger technology, and in particular to an easy-to-maintain graphite heat exchanger heat exchange component. Background Technology

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid. Graphite heat exchangers are heat exchangers whose heat transfer components are made of graphite. The graphite used to manufacture heat exchangers should be impermeable. Impermeable graphite and pressed impermeable graphite are commonly used. Graphite heat exchangers can be classified into three types according to their structure: block-hole type, shell-and-tube type, and plate type.

[0003] An existing easily replaceable and maintainable graphite heat exchanger (publication number: CN217900585U) has at least the following drawbacks: The device moves the insertion rod out by pulling the pull rod, which makes it easy to remove the limiting block from one end of the rotating shaft. This facilitates the replacement and maintenance of the graphite components. At the same time, the mounting plate can drain the condensate generated inside the heat exchanger body. However, during the heat exchange process, dirt and impurities easily accumulate inside the heat exchanger, which affects the use of the heat exchange components. It is not convenient to clean them separately, and the staff has to frequently disassemble and maintain the heat exchange components, which is cumbersome. In addition, the accumulated impurities inside can easily affect the drainage of condensate, making the operation inconvenient and ineffective. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-maintain graphite heat exchanger component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A maintainable graphite heat exchanger assembly includes a base plate, a heat exchanger body, and a graphite component. The heat exchanger body is mounted on the upper part of the base plate by fasteners. The graphite component is located inside the heat exchanger body. An inner groove is formed at the lower end of the heat exchanger body. A guide plate is fixedly installed inside the inner groove. A cleaning block is positioned above the guide plate. A fixing block is fixedly installed at one end of the cleaning block. A spring is fixedly installed between the lower end of the fixing block and the interior of the guide plate. A collection box is installed at the bottom of the guide plate. A filter plate is fixedly installed inside the collection box. A second filter plate is positioned below the first filter plate. A scraper is installed between the first filter plate and the second filter plate. The scraper is slidably connected to the interior of the collection box.

[0007] As a further embodiment of this utility model, a connecting block is fixedly provided at one end of the guide plate, a threaded rod is provided on one side of the scraper, the threaded rod is threadedly connected to the side wall of the collection box, an installation plate is fixedly installed on the outer wall of the collection box, a slot block is provided on one side of the installation plate, and a movable block is movably provided inside the installation plate.

[0008] As a further embodiment of this utility model, a second spring is fixedly installed between one end of the movable block and the inner wall of the mounting plate, and a positioning post is fixedly installed at the end of the movable block away from the second spring. The positioning post passes through the slot block and is embedded in the connecting block. The second filter plate is fixedly connected to the inner wall of the collection box, and a motor is installed on the upper end of the outer wall of the heat exchanger body by fasteners.

[0009] As a further embodiment of this utility model, a drive rod is provided below the motor, and a sealing box is provided at the end of the drive rod away from the motor. The sealing box is installed inside the heat exchanger body by fasteners. The motor is fixedly connected to one end of the drive rod through an output shaft. A bevel gear is fixedly provided at the bottom end of the drive rod, and the bevel gear passes through and connects to the upper end of the sealing box.

[0010] As a further embodiment of this utility model, a rotating rod is installed on one end of the graphite assembly near the first bevel gear via fasteners, and a second bevel gear is fixedly disposed on the rotating rod, the second bevel gear meshing with the first bevel gear. A limiting post is provided on the side of the graphite assembly away from the rotating rod, and the limiting post is connected to the graphite assembly via a rotating shaft.

[0011] As a further embodiment of this utility model, the limiting post is installed inside the heat exchanger body by fasteners, and a water outlet pipe is fixedly installed at the bottom of the collection box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. To facilitate maintenance of the graphite assembly, first install the guide plate inside the inner groove. Start the motor, causing it to drive the drive rod to rotate via the output shaft. The drive rod then drives bevel gear one to rotate, which in turn drives bevel gear two. With the cooperation of the limit post and the rotating shaft, the graphite assembly rotates inside the heat exchanger body, accelerating heat exchange efficiency. Under the elasticity of spring one, the cleaning block contacts the surface of the graphite assembly. Therefore, when the graphite assembly rotates, the cleaning block at the bottom maintains the surface of the graphite assembly, scraping off the dirt and impurities adhering to it. The fallen impurities enter the collection box through the guide plate. Filter plates one and two are used for double-layer interception and filtration of impurities. Finally, the condensate generated during heat exchange inside the heat exchanger body is discharged through the outlet pipe. The operator manually twists one end of the threaded rod to push the scraper to slide inside the collection box. The scraper cleans the filter holes on filter plates one and two, preventing clogging and ensuring proper condensate drainage. This reduces the hassle of frequent disassembly and maintenance, and facilitates subsequent processing of the collected impurities.

[0014] 2. When the collection box is full of dirt and impurities, the staff can pull the second spring outward. The elasticity of the second spring will cause the movable block to slide along the slot on the mounting plate, which will drive the positioning post to disengage from the slot block and the connecting block. Finally, the slot block will be pulled to disengage from the connecting block, thereby removing the collection box from the bottom of the guide plate. This makes it easier for the staff to handle the impurities inside the collection box separately, improving the convenience of use. Attached Figure Description

[0025] Reference Figures 1-6A maintenance-friendly graphite heat exchanger assembly includes a base plate 1, a heat exchanger body 2, and a graphite assembly 4. The heat exchanger body 2 is mounted on the upper end of the base plate 1 by fasteners. The graphite assembly 4 is located inside the heat exchanger body 2. An inner groove 805 is opened at the lower end of the heat exchanger body 2. A guide plate 101 is fixedly installed in the inner groove 805. A cleaning block 303 is arranged above the guide plate 101. A fixing block 106 is fixedly installed at one end of the cleaning block 303. A spring 302 is fixedly arranged between the lower end of the fixing block 106 and the inside of the guide plate 101. A collection box 3 is installed at the bottom of the guide plate 101. A filter plate 402 is fixedly installed inside the collection box 3. A filter plate 802 is arranged below the filter plate 402. A scraper 803 is installed between the filter plate 402 and the filter plate 802. The scraper 803 is slidably connected to the inside of the collection box 3.

[0026] In use, to facilitate maintenance of the graphite assembly 4, first install the guide plate 101 inside the inner groove 805, start the motor 202, and the motor 202 drives the drive rod 203 to rotate through the output shaft. The drive rod 203 drives the first bevel gear 104 to rotate, and the first bevel gear 104 drives the second bevel gear 105 to rotate. With the cooperation of the limiting post 102 and the rotating shaft, the graphite assembly 4 is driven to rotate inside the heat exchanger body 2, accelerating the heat exchange efficiency. Under the elasticity of the first spring 302, the cleaning block 303 abuts against the surface of the graphite assembly 4. Therefore, when the graphite assembly 4 rotates, the cleaning block 303 at the bottom maintains the surface of the graphite assembly 4. The process involves scraping off the dirt and impurities adhering to the graphite component 4. The fallen impurities enter the collection box 3 through the guide plate 101. Filter plate 1 402 and filter plate 2 802 are used for double-layer interception and filtration of impurities. Finally, the condensate generated in the heat exchanger body 2 is discharged through the water outlet pipe 8. The operator manually twists one end of the threaded rod 801 to push the scraper 803 to slide inside the collection box 3. The scraper 803 cleans the filter holes on filter plate 1 402 and filter plate 2 802 to prevent the filter holes from becoming blocked, which would affect the discharge of condensate. This reduces the tediousness of frequent disassembly and maintenance and makes it easier for the operator to process the collected impurities later.

[0027] In this embodiment, a connecting block 401 is fixedly provided at one end of the guide plate 101, a threaded rod 801 is provided on one side of the scraper 803, the threaded rod 801 is threadedly connected to the side wall of the collection box 3, an installation plate 301 is fixedly installed on the outer wall of the collection box 3, a slot block 201 is provided on one side of the installation plate 301, and a movable block 7 is movably provided inside the installation plate 301.

[0028] When in use, once the collection box 3 is full of dirt and impurities, the operator pulls the second spring 5 to move it outward. Utilizing the elasticity of the second spring 5, the movable block 7 slides along the slot on the mounting plate 301, causing the positioning post 804 to disengage from the slot block 201 and the connecting block 401. Finally, the slot block 201 is pulled away from the connecting block 401, thereby removing the collection box 3 from the bottom of the guide plate 101. This facilitates the individual processing of impurities inside the collection box 3, improving ease of use.

[0029] In this embodiment, a spring 5 is fixedly installed between one end of the movable block 7 and the inner wall of the mounting plate 301. A positioning post 804 is fixedly installed at the end of the movable block 7 away from the spring 5. The positioning post 804 passes through the connecting slot block 201 and is embedded in the connecting block 401. The filter plate 802 is fixedly connected to the inner wall of the collection box 3. A motor 202 is installed on the upper end of the outer wall of the heat exchanger body 2 by fasteners.

[0030] In use, by utilizing the elasticity of spring 25, the positioning post 804 is pushed into the slot block 201 and the connecting block 401, thereby installing the collection box 3 at the bottom of the guide plate 101, which strengthens the connection and makes it easy to disassemble and remove the collection box 3.

[0031] In this embodiment, a drive rod 203 is provided below the motor 202, and a sealing box 6 is provided at the end of the drive rod 203 away from the motor 202. The sealing box 6 is installed inside the heat exchanger body 2 by fasteners. The motor 202 is fixedly connected to one end of the drive rod 203 through the output shaft. A bevel gear 104 is fixedly provided at the bottom end of the drive rod 203, and the bevel gear 104 passes through and connects to the upper end of the sealing box 6.

[0032] In use, the cleaning block 303 is made of silicone. The spring 302 causes the cleaning block 303 to contact the graphite component 4, thereby scraping off the dirt and impurities adhering to the graphite component 4, while avoiding wear on the surface of the graphite component 4. The motor 202 is model JSMA-PUC02D.

[0033] In this embodiment, a rotating rod 103 is installed on one end of the graphite assembly 4 near the first bevel gear 104 by fasteners. A second bevel gear 105 is fixedly installed on the rotating rod 103. The second bevel gear 105 meshes with the first bevel gear 104. A limiting post 102 is provided on the side of the graphite assembly 4 away from the rotating rod 103. The limiting post 102 is connected to the graphite assembly 4 through a rotating shaft.

[0034] In use, the limiting post 102 is used to support and limit the graphite component 4. With the cooperation of the rotating shaft, the graphite component 4 can rotate stably and prevent it from falling off. The first filter plate 402 and the second filter plate 802 are used to intercept and filter the solid impurities contained in the condensate in a double layer, which facilitates the discharge of the condensate.

[0035] In this embodiment, the limiting post 102 is installed inside the heat exchanger body 2 by fasteners, and the bottom end of the collection box 3 is fixedly installed with a water outlet pipe 8.

[0036] In use, both filter plate 402 and filter plate 802 have several filter holes. The scraper 803 is pushed by the threaded rod 801 to slide inside the collection box 3, so that the scraper 803 cleans the filter holes on filter plate 402 and filter plate 802, preventing the filter holes from becoming blocked and facilitating individual cleaning.

[0037] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In order to facilitate the maintenance of the graphite assembly 4, the guide plate 101 is first installed in the inner groove 805. The motor 202 is started, so that the motor 202 drives the drive rod 203 to rotate through the output shaft. The drive rod 203 drives the bevel gear 104 to rotate, and the bevel gear 104 drives the bevel gear 205 to rotate. With the cooperation of the limiting post 102 and the rotating shaft, the graphite assembly 4 is driven to rotate inside the heat exchanger body 2, thereby accelerating the heat exchange efficiency. Under the elasticity of the spring 302, the cleaning block 303 abuts against the surface of the graphite assembly 4. Therefore, when the graphite assembly 4 rotates, the cleaning block 303 at the bottom maintains the surface of the graphite assembly 4, scraping off the dirt and impurities adhering to the graphite assembly 4. The fallen impurities enter the collection box 3 through the guide plate 101. The filter plate 1 402 and the filter plate 2 802 are used to perform double-layer interception and filtering of impurities. After filtration, the condensate generated in the heat exchanger body 2 is discharged through the outlet pipe 8. The operator manually twists one end of the threaded rod 801 to push the scraper 803 to slide inside the collection box 3. The scraper 803 cleans the filter holes on the first filter plate 402 and the second filter plate 802 to prevent the filter holes from becoming clogged and affecting the discharge of condensate, reducing the hassle of frequent disassembly and maintenance, and making it easier for the operator to process the collected impurities. When the collection box 3 is full of dirt and impurities, the operator pulls the second spring 5 to move it outward. Using the elasticity of the second spring 5, the movable block 7 slides along the slot on the mounting plate 301, causing the positioning post 804 to disengage from the slot block 201 and the connecting block 401. Finally, the slot block 201 is pulled away from the connecting block 401, thereby removing the collection box 3 from the bottom of the guide plate 101. This makes it easier for the operator to process the impurities inside the collection box 3 separately, improving the convenience of use.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
