Description
Technical Field
[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat recovery device for granulation towers. Background Technology
[0002] With the development of the times, people are using various new materials more and more widely. In the production of materials such as microcrystalline super wear-resistant balls, wear-resistant bricks, kiln temperature-sealed sand, and ceramic materials, the use of granulation towers is indispensable. However, the production process of using granulation towers will release a large amount of hot air. Directly releasing this air will result in a large amount of energy waste, making it difficult to meet the actual use requirements. Therefore, it is necessary to use waste heat recovery devices for operation.
[0003] However, traditional waste heat recovery devices are difficult to filter impurities and dust carried in the hot air emitted from the granulation tower during use, which will pollute the air after emission and thus fail to meet actual use requirements. In addition, it is not easy to monitor whether the liquid temperature has reached the critical value during the heat transfer process, and continued heating may result in waste, which will affect the efficiency of waste heat recovery. Utility Model Content
[0004] The purpose of this invention is to provide a waste heat recovery device for granulation towers, which solves the shortcomings of existing waste heat recovery devices for granulation towers, such as inconvenience in filtering the hot gas discharged from the granulation tower and poor waste heat recovery efficiency.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste heat recovery device for a granulation tower, comprising a main body and an air inlet;
[0006] An air inlet is provided on one side of the top of the main body, and a curved tube is installed on one side of the air inlet inside the main body. A filter structure is provided inside the air inlet.
[0007] A water inlet is provided on one side of the top of the main body, and a water inlet valve is provided inside the water inlet. A drain outlet is provided at the bottom of the main body, and a drain valve is provided inside the drain outlet. A monitoring structure is provided on one side of the bottom of the main body.
[0008] The monitoring structure includes a through groove, a slide groove, a baffle, a limiting spring, a detection seat, a fixing plate, a detection column, and a temperature display screen. The through groove is located on one side of the bottom of the main body. Slide grooves are provided on both sides of the through groove. A baffle is provided inside each slide groove. A limiting spring is fixed on one side of each baffle. A detection seat is provided inside the through groove. Fixing plates are fixed on both sides of the detection seat. A detection column is installed on one side of the detection seat. A temperature display screen is provided on the side of the detection seat away from the detection column.
[0009] Preferably, the filter structure includes a mounting groove, an inclined block, a return spring, a pull plate, a mounting base, a snap-fit groove, and a filter plate. The mounting groove is located inside the air inlet. Inclined blocks are provided on both sides of the mounting groove. A return spring is fixed to one side of each inclined block. A pull plate is fixed to the top of each inclined block. A mounting base is provided inside the mounting groove. Snap-fit grooves are provided on both sides of the mounting base. A filter plate is installed at the bottom of the mounting base.
[0010] Preferably, the inclined blocks are symmetrically distributed on both sides of the mounting groove, and the side of the reset spring away from the inclined blocks is fixedly connected to one side inside the mounting groove.
[0011] Preferably, the filter plate abuts against the inner wall of the air inlet, and the snap-fit grooves are symmetrically distributed on both sides of the mounting base.
[0012] Preferably, one side of the inclined block is disposed inside the snap-fit groove, and the inclined block and the mounting base form a snap-fit structure through the snap-fit groove.
[0013] Preferably, the baffle is slidably connected inside the groove, and the detection column extends into the interior of the main body.
[0014] Preferably, the fixing plates are all disposed on one side of the sliding groove on both sides of the through groove, and the fixing plates and the through groove form an engaging structure.
[0015] The waste heat recovery device for granulation towers provided by this utility model has the following advantages:
[0016] By setting up a monitoring structure, the baffles on both sides are pulled to facilitate the installation of the detection seat into the through groove, and the fixing plate is placed on both sides of the through groove. The baffles are then released, allowing the detection seat to move to one side of the fixing plate by the elastic force of the limit spring, thereby positioning it. The detection column detects the temperature of the liquid inside the main body and transmits it to the temperature display screen for display, thereby constantly monitoring whether the liquid inside the main body has been heated to the critical value. The detection seat can also be easily removed by pulling the baffles, thus achieving the purpose of improving the waste heat recovery efficiency and facilitating the disassembly and maintenance of the temperature detection device.
[0017] By incorporating a filtration structure, the mounting base is pressed directly into the mounting groove during filter plate installation. The inclined edge of the block then presses the plate against one side of the groove. When the locking groove moves to one side of the inclined block, a return spring pushes the inclined block into the locking groove, thus locking the mounting base in place. During removal, simply pull the pull plate to move the inclined block away from the locking groove. This design facilitates the filtration of hot gas discharged from the granulation tower and makes the filter plates easy to disassemble and maintain. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figures 1-5 The present invention provides a waste heat recovery device for a granulation tower, comprising a main body 1 and an air inlet 2.
[0026] Reference Figure 1 and Figure 3As shown, an air inlet 2 is provided on one side of the top of the main body 1. A curved pipe 3 is installed on one side of the air inlet 2 inside the main body 1. A filter structure 4 is provided inside the air inlet 2. The filter structure 4 includes a mounting groove 401, a wedge block 402, a return spring 403, a pull plate 404, a mounting base 405, a snap-fit groove 406, and a filter plate 407. The mounting groove 401 is located inside the air inlet 2. Wedge blocks 402 are provided on both sides of the mounting groove 401. A return spring 403 is fixed on one side of each wedge block 402. A pull plate 404 is fixed to the top of each wedge block 402. The interior of the mounting groove 401... The unit is provided with a mounting base 405, and both sides of the mounting base 405 are provided with snap-fit grooves 406. A filter plate 407 is installed at the bottom of the mounting base 405. Inclined blocks 402 are symmetrically distributed on both sides of the mounting groove 401. The side of the return spring 403 away from the inclined block 402 is fixedly connected to one side inside the mounting groove 401. The filter plate 407 abuts against the inner wall of the air inlet 2. The snap-fit grooves 406 are symmetrically distributed on both sides of the mounting base 405. One side of the inclined block 402 is set inside the snap-fit groove 406. The inclined block 402 and the mounting base 405 form a snap-fit structure through the snap-fit groove 406.
[0027] The production process of microcrystalline super wear-resistant balls, wear-resistant bricks, kiln temperature-sealed sand, and ceramic materials using a granulation tower generates a large amount of heat. Directly discharging this heat would result in unnecessary energy waste. Therefore, the residual heat can be recovered and utilized. The hot air enters the interior of the curved tube 3 through the air inlet 2. The curved tube 3 meanders inside the main body 1, thereby heating the water inside the main body 1 and utilizing the residual heat. To prevent the hot air containing a large amount of dust from being directly discharged and causing air pollution, it needs to be filtered. A filter structure 4 is provided to facilitate the filtration of the hot air discharged from the granulation tower through the filter plate 407. The mounting base 405 is positioned by the engaging structure formed by the inclined block 402 and the locking groove 406, which facilitates pulling the pull plate 404 to move the inclined block 402 away from the interior of the locking groove 406, thus facilitating the removal of the mounting base 405 for cleaning and maintenance of the filter plate 407, thereby greatly increasing the functionality of the device.
[0028] Reference Figure 4 and Figure 5As shown, a water inlet 5 is opened on one side of the top of the main body 1, and a water inlet valve 6 is installed inside the water inlet 5. A drain outlet 7 is opened at the bottom of the main body 1, and a drain valve 8 is installed inside the drain outlet 7. A monitoring structure 9 is opened on one side of the bottom of the main body 1. The monitoring structure 9 includes a through groove 901, a slide groove 902, a baffle 903, a limit spring 904, a detection seat 905, a fixing plate 906, a detection column 907, and a temperature display screen 908. The through groove 901 is opened on one side of the bottom of the main body 1, and slide grooves 902 are opened on both sides of the through groove 901. A baffle 902 is installed inside each slide groove 902. 3. Limiting springs 904 are fixed on one side of the baffle 903. A detection seat 905 is provided inside the through groove 901. Fixing plates 906 are fixed on both sides of the detection seat 905. A detection column 907 is installed on one side of the detection seat 905. A temperature display screen 908 is provided on the side of the detection seat 905 away from the detection column 907. The baffle 903 is slidably connected inside the slide groove 902. The detection column 907 extends into the interior of the main body 1. Fixing plates 906 are all provided on one side of the slide groove 902 on both sides of the through groove 901. The fixing plates 906 and the through groove 901 form a locking structure through the slide groove 902.
[0029] When using the exhaust heat to heat the liquid entering the main body 1 through the inlet 5, the temperature of the liquid in the main body 1 may reach a critical value. If the liquid is not discharged but continues to be heated, the utilization rate of the residual heat will be reduced, making it difficult to meet the actual use requirements. Therefore, by setting up a monitoring structure 9, the device can easily detect the temperature of the liquid inside the main body 1 through the detection column 907 installed with the detection seat 905 and transmit it to the temperature display screen 908. When the liquid temperature reaches the critical value, the drain valve 8 is opened to discharge the liquid, and the inlet valve 6 is opened to allow new liquid to enter. It is also easy to pull the baffle 903 away from the fixed plate 906, which facilitates the disassembly and maintenance of the detection seat 905, thus greatly increasing the practicality of the device.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
