[0018] Compared with the related art, the waste heat recovery mechanical manufacturing grinding device provided by the present invention has the following beneficial effects:

[0019] 1. In the waste heat recovery unit, when the fan is working, the air intake cover can be used to absorb the heat generated during grinding, and the heat can be introduced into the inside of the loading platform through the pipeline structure. The inside of the loading platform is a cavity structure, and the cavity is used to concentrate the heat; at the same time, the workpiece to be processed can be placed on the loading platform. At this time, the heat inside the cavity is transferred to the workpiece to achieve heat treatment of the workpiece, thereby further improving the plasticity of the workpiece, so that it is easier to remove the oxide layer or other impurities on the surface during grinding, and the deformation resistance of the metal after heating will be reduced, so that the wear of the tool can be reduced during grinding, and grinding can be performed more efficiently, thereby further improving the grinding quality and realizing heat recovery and reuse;

[0020] 2. The air intake cover is installed on the grinding device, and the grinding device can be driven to move in space through the adjustment mechanism, and then the cover can be driven to move together, so that the air intake cover is always located beside the grinding device, that is, always in the area with the highest temperature, so the heat recovery effect is better;

[0021] 3. The installation tube in the filter-type guide is installed in the pipeline structure for conveying heat, and is used to intercept the grinding waste chips contained in the pipeline, so as to facilitate the subsequent cleaning of the waste chips. In addition, a rotatable impeller is provided inside the installation tube. When the airflow circulates rapidly inside the installation tube, the airflow acts on the impeller, thereby generating a torque on the impeller. Under the action of the torque, the impeller rotates rapidly, thereby driving the brush plate to rotate through the rotating shaft. The brush plate contacts the convex surface of the filter screen, and can scrape off the waste chips attached to the filter screen when rotating, thereby cleaning the filter screen and ensuring the smoothness of the entire airflow.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0038] See also Figures 1 to 7 , an embodiment of the present invention provides a waste heat recovery mechanical manufacturing grinding device, the waste heat recovery mechanical manufacturing grinding device comprises:

[0039] A workbench 1, a fourth support frame 3 is fixed on one side of the workbench 1, and a loading platform 5 is also fixed on the other side of the workbench 1. The loading platform 5 has a cavity penetrating the upper end surface, and a plurality of support plates 51 for placing the plates to be processed are provided on the top of the cavity. A plurality of balls 52 for supporting the plates to be processed are embedded in the upper end of any support plate 51, and a temperature detector 6 for monitoring the internal temperature of the loading platform 5 is also fixed on the outer wall of the loading platform 5;

[0040] An adjusting mechanism is installed on the workbench 1, a grinding device 2 is fixed on the adjusting mechanism, the grinding device 2 is used to grind the workpiece, and the adjusting mechanism can drive the grinding device 2 to move in space to achieve a comprehensive grinding operation on the workpiece;

[0041] The waste heat recovery unit 4 is installed on the fourth support frame 3, and is used to absorb the heat generated by the grinding operation and conduct the heat to the cavity inside the loading platform 5 to heat the workpiece to be processed placed on the support plate 51.

[0042] It should be noted that in the device, the workbench 1 is a platform for placing the workpiece, and then the workpiece can be polished by the polishing device 2, and the loading platform 5 is used to place the workpiece to be processed, that is, after the workpiece on the workbench 1 is polished, the workpiece on the loading platform 5 can be transferred to the workbench 1, and then a new workpiece to be processed (such as Figure 1 As shown, the direction indicated by the arrow is the unloading direction, and the plate that has been polished on the workbench 1 can be taken out from this position), and a ball 52 is also arranged on the support plate 51. On the one hand, the ball 52 can be used to support the plate to be processed, and at the same time, it can also assist in the transportation of the workpiece, which is convenient for the loading operation. At the same time, a temperature detector 6 is also installed on the loading platform 5. The probe of the temperature detector 6 is located in the cavity inside the loading platform 5 to monitor the internal temperature thereof, so as to ensure that the heat can always be in the most suitable state;

[0043] The waste heat recovery unit 4 is used to recover the heat generated during the grinding operation, thereby realizing heat recovery. At the same time, the recovered heat can be introduced into the cavity inside the loading platform 5 to increase the temperature inside the cavity. The workpiece to be processed is located at the upper opening of the cavity, so the workpiece can be heat treated to increase the temperature of the plate, thereby further improving the plasticity of the workpiece, making it easier to remove the oxide layer or other impurities on the surface during grinding, and the deformation resistance of the metal after heating will be reduced, which can reduce the wear on the tool during grinding, and can also grind more efficiently, thereby further improving the grinding quality and realizing heat recovery and reuse.

[0044] In the embodiments of the present invention, please refer to Figure 3The adjustment mechanism includes a base frame 21, the base frame 21 is fixed on the workbench 1, a horizontally arranged first track plate 22 is fixed on one side of the base frame 21, a first slide 23 is movably mounted on the first track plate 22, a first support frame 24 is fixed on one side of the first slide 23, a pedestal 25 along the vertical direction is fixed on the upper end of the first support frame 24, a second slide 26 is movably mounted on one side of the pedestal 25, a second track plate 27 arranged in the horizontal direction and perpendicular to the first track plate 22 is fixed on one side of the second slide 26, and a third slide 28 is movably mounted on the second track plate 27;

[0045] The grinding device 2 includes a second support frame 29, which is fixed on the third slide 28. A motor 210 is installed on the second support frame 29. The output end of the motor 210 faces downward and is fixed with a grinding disc 211 for driving the grinding disc 211 to rotate horizontally. A third support frame 212 for installing the air intake cover plate 46 is also fixed on the second support frame 29.

[0046] It should be noted that: in the adjustment mechanism, the first slide 23 moves horizontally on the first track plate 22, the second slide 26 moves vertically on the pedestal 25, and the third slide 28 moves horizontally on the second track plate 27, and its moving direction is perpendicular to the moving direction of the first slide 23. The grinding device 2 is fixed on the third slide 28, so it can drive the grinding device 2 to move along the X, Y and Z directions to adjust the position of the grinding device 2. On the one hand, it can improve the contact effect between the grinding device 2 and the plate, and on the other hand, it can achieve thorough grinding of the plate.

[0047] In the grinding device 2 , the motor 210 can directly drive the grinding disc 211 to rotate, and the grinding disc 211 is used to grind the plate.

[0048] In the embodiments of the present invention, please refer to Figure 4 The waste heat recovery unit 4 includes a fan 41, an air inlet port of the fan 41 is connected to an air inlet cover plate 46 through a spiral hose 45, the air inlet cover plate 46 is fixed on the grinding device 2, and moves synchronously with the grinding device 2, and a filter-type flow guide 48 is fixed to the air outlet port of the fan 41 through an air outlet pipe 47;

[0049] An air inlet pipe 42 is fixed to the air inlet port of the fan 41 , a first valve pipe 43 is fixed to the other end of the air inlet pipe 42 , a spiral hose 45 is fixed to the other end of the first valve pipe 43 , and a second valve pipe 44 is also fixed to the circumferential outer wall of the air inlet pipe 42 .

[0050] It should be noted that: in the waste heat recovery unit 4, the fan 41 is used as the driving source, and the air intake end thereof is fixed to the air intake cover plate 46 through the spiral hose 45. Therefore, when the fan 41 is working, the air intake cover plate 46 can absorb the heat, and then introduce the heat into the air outlet pipe 47, and then introduce the heat into the internal cavity of the loading platform 5 through the filter guide 48, so as to realize the recovery of the heat;

[0051] The air intake cover plate 46 is fixed on the third support frame 212, and its opening faces the position of the grinding disc 211. Therefore, when the grinding device 2 is driven to move by the adjustment mechanism, the air intake cover plate 46 can also be driven to move together, so that the air intake cover plate 46 is always located beside the grinding device 2, that is, always located in the area with the highest temperature, so that the heat recovery effect is better;

[0052] It should also be noted that: the air inlet pipe 42 is provided with a first valve pipe 43 and a second valve pipe 44. When performing heat recovery operation, the first valve pipe 43 is in an open state, and the second valve pipe 44 is in a closed state, so that normal heat absorption can be performed; when cleaning impurities, the first valve pipe 43 is closed and the second valve pipe 44 is opened. At this time, the speed of the fan 41 can be increased, and the air flow rate entering the interior thereof is faster. At the same time, the second valve pipe 44 is used as the air inlet, which is far away from the workbench 1, so the impurity content in the air entering the interior thereof will be relatively low.

[0053] In the embodiments of the present invention, please refer to Figure 5 and Figure 6 The filter-type flow guide 48 includes a mounting tube 481, which is fixed to the outer wall of the loading platform 5, and communicates with the internal cavity of the communication vessel and the air outlet pipe 47. A filter screen 482 is fixed inside the mounting tube 481. The filter screen 482 is hemispherical, with the convex surface facing the upstream direction of the air flow channel inside the mounting tube 481. The filter screen 482 is penetrated by a rotating shaft 483 connected with a bearing. An impeller 484 is fixed at one end of the rotating shaft 483, and a plurality of annularly distributed brush plates 485 are fixed at the other end. The brush plates 485 are in contact with the filter screen 482.

[0054] A waste storage pipe 486 is fixed on the circumferential outer wall of the installation pipe 481 and corresponds to the convex surface of the filter screen 482 , and a third valve pipe 487 for controlling the opening and closing of the waste storage pipe 486 is fixed at the lower end thereof.

[0055] It should be noted that: for the filter-type flow guide 48, the installation pipe 481 is the main flow guide structure, one end of which is fixed to the outer wall of the loading platform 5 to achieve communication with the internal cavity of the loading platform 5, and the other end is connected to the air outlet pipe 47, so that the air outlet pipe 47 can introduce heat into the internal cavity of the loading platform 5 through the installation pipe 481. At the same time, there is a filter screen 482 inside the installation pipe 481, and the filter screen 482 can intercept waste chips in the airflow;

[0056] When the heat is absorbed, the speed of the fan 41 is low, and the airflow velocity entering the installation pipe 481 is low. When acting on the impeller 484, it cannot drive the impeller 484 to rotate. When impurities are processed, the speed of the fan 41 is increased, so the airflow velocity is faster. When acting on the impeller 484, a torque can be generated on the impeller 484. Under the action of the torque, the impeller 484 rotates rapidly, thereby driving the brush plate 485 to rotate through the rotating shaft 483. The brush plate 485 contacts the convex surface of the filter screen 482, and can scrape off the waste attached to the filter screen 482 when rotating, so as to clean the filter screen 482 and ensure the smoothness of the entire airflow. The cleaned impurities will fall into the waste storage pipe 486. The third valve pipe 487 is subsequently opened to discharge the impurities, so as to clean the impurities.

[0057] The filter screen 482 is hemispherical in shape, with the convex surface facing upward and upstream of the inside of the mounting tube 481 , so that after impurities fall onto the filter screen 482 , it is easier to clean.

[0058] The specific use process of the device is as follows:

[0059] (1) Polishing of panels;

[0060] First, a workpiece is placed on the workbench 1, and a workpiece to be processed is placed on the loading table 5, and then the grinding device 2 is driven to move by the adjustment mechanism, so that the grinding disc 211 and the plate are in contact, and the plate is grinded by rotation, and at the same time, the grinding device 2 is driven to move in the horizontal direction by the adjustment mechanism to achieve comprehensive grinding of the plate;

[0061] (2) Waste heat recovery:

[0062] During the grinding process of the plate, the fan 41 is turned on, the air intake cover plate 46 absorbs the heat, and conducts the heat to the cavity inside the loading platform 5 through the pipeline structure. At this time, the workpiece to be processed placed on the upper end of the loading platform 5 is affected by the heat, and after the heat treatment is completed, the grinding quality of the plate can be improved;

[0063] (3) Impurity cleaning:

[0064] When it is necessary to clean the impurities, the first valve tube 43 is closed and the second valve tube 44 is opened, and the rotation speed of the fan 41 is increased at the same time. At this time, the flow rate of the airflow entering the pipeline is faster. When the airflow circulates quickly inside the installation tube 481, the airflow acts on the impeller 484, thereby generating a torque on the impeller 484. Under the action of the torque, the impeller 484 rotates rapidly, thereby driving the brush plate 485 to rotate through the rotating shaft 483, and the brush plate 485 contacts the convex surface of the filter screen 482. When rotating, it can scrape off the waste debris attached to the filter screen 482, thereby cleaning the filter screen 482.

[0065] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
