DETAILED DESCRIPTION

[0016] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0017] Please refer to Figures 1 to 3 As shown, a waste heat recovery device for papermaking equipment of the present invention includes a water tank base 2, a drive laminating mechanism and a heat recovery component. The heat recovery component is arranged on both sides of the water tank base 2. The heat recovery component is connected to the drive laminating mechanism, and the drive laminating mechanism is connected to the water tank base 2. A water inlet assembly is provided on one side of the water tank base 2, and a drainage assembly is provided on the other side of the water tank base 2; The heat energy recovery component includes a heat conduction plate 11, a first circulation pipe 7, a second circulation pipe 8 and a guide pump 14. One side of the heat conduction plate 11 is connected to the drive fitting mechanism through an elastic collapse member 16. The upper part of the heat conduction plate 11 is connected to the water tank base 2 through the first circulation pipe 7. The lower part of the heat conduction plate 11 is connected to the water tank base 2 through the second circulation pipe 8. The first circulation pipe 7 and the second circulation pipe 8 are both connected to a guide pump 14.

[0018] The working principle of the present invention is as follows: in the actual papermaking process, the pulp cooker can be placed on the water tank base 2. When it is necessary to recover the heat after the pulping is completed, the driving and fitting mechanism can be operated to drive the heat conducting plates 11 on both sides to clamp the pulp cooker. Then the heat of the pulp cooker is transferred to the heat conducting plates 11. At the same time, two guide pumps 14 are operated, so that one guide pump 14 guides the water in the water tank base 2 into the interior of the heat conducting plate 11 through the second circulation pipe 8. At the same time, the other guide pump 14 guides the water inside the heat conducting plate 11 into the water tank base 2 to complete the circulation and take away the heat of the heat conducting plate 11. After the pulp cooker cools down, the internal pulp is taken out, and then the drainage component is operated to enable the drainage component to guide the water that absorbs heat in the water tank base 2 into the pulp cooker.

[0019] Furthermore, a cooling cavity is provided inside the heat conducting plate 11 , and the cooling cavity is connected to the water tank base 2 through the first circulation pipe 7 and the second circulation pipe 8 .

[0020] As can be seen from the above description, it is beneficial to introduce water into the water tank base 2 so that the water circulates and cools through the guide pump 14, the first circulation pipe 7 and the second circulation pipe 8.

[0021] Furthermore, a plurality of heat conducting rods 15 are fixedly connected to the inner surface of the heat conducting plate 11 .

[0022] From the above description, it can be seen that this is beneficial to improving the heat conduction effect.

[0023] Furthermore, the driving bonding mechanism includes a bidirectional driving component and two bonding plates 1, and a bonding plate 1 is arranged on both sides of the bidirectional driving component. One bonding plate 1 is connected to one side of the heat conducting plate 11 through the elastic collapse member 16.

[0024] From the above description, it can be seen that when it is necessary to control the heat conduction plate 11 to clamp the pulp cooker, the bidirectional drive component can be operated to drive the two heat conduction plates 11 closer through the bonding plate 1 and clamp the pulp cooker through the heat conduction plate 11.

[0025] Furthermore, the bidirectional drive assembly includes a guide rail 4, a bidirectional screw 6, a slider 5 and a rotating drive member 18. The guide rail 4 is fixedly connected to the water tank base 2. The bidirectional screw 6 is rotatably connected to the inside of the guide rail 4. A slider 5 is slidably connected to both sides of the guide rail 4. The sliders 5 are connected to the bidirectional screw 6. The rotating drive member 18 is rotationally driven and connected to the bidirectional screw 6. The sliders 5 are respectively fixedly connected to one of the bonding plates 1.

[0026] From the above description, it can be seen that when it is necessary to move the bonding plate 1, the rotating drive member 18 can be operated to drive the bidirectional screw 6 to rotate, so that the bidirectional screw 6 drives the sliders 5 on both sides to slide on the guide rail 4 and drive the bonding plate 1 to move closer.

[0027] Furthermore, the water inlet assembly includes a water inlet pipe 3 and a water inlet pump 13 . The water inlet pipe 3 is provided on the water tank base 2 , and the water inlet pump 13 is provided inside the water inlet pipe 3 .

[0028] From the above description, it can be seen that it is beneficial for the water inlet pump 13 to introduce water into the water tank base 2 through the water inlet pipe 3.

[0029] Furthermore, the drainage assembly includes a drain pipe 9, a drain pump 17 and a telescopic tube 10. One end of the drain pipe 9 is connected to the water tank base 2. The drain pump 17 is provided inside the drain pipe 9. The telescopic tube 10 is provided at the other end of the drain pipe 9.

[0030] From the above description, it can be seen that it is beneficial to guide the water in the water tank base 2 into the pulp cooker through the drainage pump 17 and the telescopic tube 10, and the water outlet position can be better adjusted through the telescopic tube 10.

[0031] Furthermore, it also includes a placement pad 12, and the placement pad 12 is provided in the middle of the water tank base 2.

[0032] As can be seen from the above description, it is beneficial to place the pulp cooker on the water tank base 2 through the placement pad 12 to prevent the pulp cooker from moving.

[0033] Furthermore, it also includes a controller, which is electrically connected to the driving and laminating mechanism and the heat recovery component respectively.

[0034] As can be seen from the above description, it is more convenient for the user to control the entire device. Example
