Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water-containing solid waste recovery, in particular to a multi-return heat dissipation device. Background Art
[0002] Water-containing solid waste is a common type of industrial solid waste, such as industrial gypsum (including phosphogypsum, titanium gypsum, desulfurized gypsum, etc.), sludge, alkali residue, etc., which usually have a high water content and need to be dried before they can be used. For example, phosphogypsum, as a common industrial by-product, is also called expanded gypsum, phosphating gypsum or calcium phosphate gypsum. It is the remaining product after calcium phosphate is extracted from phosphate ore by the sulfuric acid method during the phosphoric acid production process. The cementing properties of phosphogypsum are lower than those of natural gypsum, and the viscosity and fluidity are also worse than those of natural gypsum. The phosphogypsum slurry takes a long time to set and has certain corrosiveness. And phosphogypsum usually has a high water content of about 20%. After drying, it can be used as a cementing material in fluidized soil backfill and pipe pile materials.
[0003] In the current recycling process, it is necessary to mix water-containing solid waste and desiccant (such as quicklime). During the mixing process, the quicklime quickly heats up when it meets water, so the heat sink needs to be used for heat dissipation during the recycling process. In order to fully reduce the temperature of the mixture, the existing heat sink needs to set up a longer conveying platform to extend the heat dissipation process. Therefore, the heat sink body is relatively long, the manufacturing cost is high, and the floor space is large. In addition, the transmission device and conveyor chain of the conveying platform are prone to wear and breakage under the pressure of the mixture, which makes the maintenance frequency high, seriously affecting the production efficiency.

[0008] As a further description of the above technical solution, the discharge port of the first body is connected to the feed port of the second body, and the feed port of the third body is connected to the discharge port of the second body.

[0012] As a further description of the above technical solution, there is an angle between the scraper and the conveyor belt, and the angle ranges from 90-120°.
[0013] As a further description of the above technical solution, a heat dissipation mechanism is arranged below the heat dissipation machine body, and the heat dissipation medium cools the heat dissipation machine body through the heat dissipation mechanism.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0025] Embodiment 1:
[0026] like Figure 1-Figure 2 As shown, in one embodiment, a multi-return heat dissipation device includes: a plurality of heat dissipation machine bodies 1 stacked from top to bottom, and the discharge port 15 of the adjacent heat dissipation machine body 1 is connected to the feed port 14 of another heat dissipation machine body 1 to form a multi-return conveying channel. By using a plurality of longitudinally arranged heat dissipation machine bodies 1, compared with the existing heat dissipation machine bodies 1, more equipment or other production lines can be accommodated in the same space while increasing the distance for material heat dissipation, effectively reducing the floor space of the equipment and reducing production costs.
[0027] Furthermore, a dust collector is connected to one side of the heat sink body 1. The dust collector adopts a pulse bag dust collector, which uses bag filter material as the filter medium, has high reliability and durability, can operate stably for a long time, reduces equipment failures and downtime, and improves production efficiency.
[0028] Please continue reading Figure 1-Figure 2 In this embodiment, three bodies are taken as an example, including a first body 11, a second body 12 and a third body 13. A feed port 14 is provided on the upper side of the heat sink body 1, and a discharge port 15 is provided on the other side below the heat sink body 1.
[0029] Among them, the discharge port 15 of the first body 11 is connected to the feed port 14 of the second body 12, and the discharge port 15 of the second body 12 is connected to the feed port 14 of the third body 13. After the mixture enters from the feed port 14 of the first body 11, it is diluted and turned over, and then enters the feed port 14 of the second body 12 from the discharge port 15 of the first body 11; after the mixture is diluted and turned over again, it enters the feed port 14 of the third body 13 from the discharge port 15 of the second body 12; after the mixture is diluted and turned over again, it is discharged from the discharge port 15 of the third body 13.
[0030] The multi-return conveying channel realizes the continuous conveying of materials between multiple heat sink bodies 1, effectively improving the heat dissipation efficiency. Specifically, the multi-return conveying channel inside the heat sink body 1 is S-shaped, and the rotation stroke of the heat sink body 1 is 30-50m. Preferably, the rotation stroke is 40m, which reduces the total processing time while ensuring the heat dissipation efficiency.
[0031] Moreover, in the process of the material entering the feed port 14 of the next heat sink body 1 through the discharge port 15 of the previous heat sink body 1, the material falls from the conveyor chain 3 of the previous heat sink body 1 and freely falls onto the conveyor chain 3 of the next heat sink body 1. Not only is the free fall process beneficial to the heat dissipation of the material, but this process can also make the material originally located at the bottom of the conveyor chain 3 of the previous heat sink body 1 fall to the top of the conveyor chain 3 of the next heat sink body 1. The three bodies can be flipped twice, which has a better heat dissipation effect than traditional linear heat dissipation equipment.
[0032] Please continue reading Figure 1-Figure 2 In this embodiment, a driving device 2 and a conveying chain 3 are provided in the heat sink body 1. Specifically, the driving device 2 is a driving motor, and the conveying chain 3 is a ring-shaped conveying chain. During operation, the driving motor drives the conveying chain, thereby realizing smooth conveying of the mixed material.
[0033] Please continue reading Figure 1-Figure 2 In this embodiment, multiple groups of scrapers 4 are equidistantly fixed on the ring chain, and the scrapers 4 are used to thin and flip the mixture. Among them, the scraper 4 device extends along the width direction of the conveyor belt, and its width is greater than or equal to the width of the conveyor chain 3, which effectively prevents the material from flowing out from the gap between the scraper 4 and the conveyor chain 3; an angle is set between the scraper 4 and the conveyor chain 3. Compared with the vertical setting, the width of the inclined scraper 4 can be larger. At the same height, the contact area with the mixture is further increased, and the mixture is more effectively evenly distributed on the conveyor belt. Specifically, the angle ranges from 90-120°, preferably, the angle ranges from 100-120°, and the spacing of the scrapers 4 is 150-350mm. Preferably, the spacing of the scrapers 4 is 200-300mm.
[0034] Embodiment 2:
[0035] Please continue reading Figure 1-Figure 2 In this embodiment, four bodies are taken as an example, including a first body 11, a second body 12, a third body 13 and a fourth body. A feed inlet 14 is provided on the upper side of the heat sink body 1, and a discharge port 15 is provided on the other side below the heat sink body 1.
[0036] Among them, the discharge port 15 of the first body 11 is connected to the feed port 14 of the second body 12, and the feed port 14 of the third body 13 is connected to the discharge port 15 of the second body 12. After the mixture enters from the feed port 14 of the first body 11, it is diluted and turned over, and then enters the feed port 14 of the second body 12 from the discharge port 15 of the first body 11; after the mixture is diluted and turned over again, it enters the feed port 14 of the third body 13 from the discharge port 15 of the second body 12; after the mixture is diluted and turned over again, it enters the feed port 14 of the fourth body from the discharge port 15 of the third body 13; after the mixture is diluted and turned over again, it is discharged from the discharge port 15 of the fourth body.
[0037] As the number of heat sink bodies 1 increases, the temperature of the discharged mixed material gradually decreases until it reaches the required temperature.
[0038] Embodiment three:
[0039] Please continue reading Figure 1-Figure 2 In this embodiment, a heat dissipation mechanism 16 is provided under the heat dissipation machine body 1. The heat dissipation mechanism 16 takes away the heat generated in the mixture by air cooling or water cooling, thereby effectively reducing the temperature of the heat dissipation machine body 1.
[0040] Specifically, the heat dissipation mechanism 16 is a box body, which is a hollow structure. A cooling medium such as water or air flows through one end of the box body to take away the heat of the heat dissipation machine body 1, thereby achieving a heat dissipation effect.
[0041] Embodiment 4:
[0042] Please continue reading Figure 1-Figure 2 In this embodiment, the heat dissipation mechanism 16 can also be a pipe or other channel through which the heat dissipation medium can pass. The pipe is installed below the heat dissipation machine body 1 through a pipe bracket, and the pipe is in contact with the heat dissipation machine body 1. The cooling medium flows through the pipe through one end of the pipe to take away the heat of the heat dissipation machine body 1. Specifically, the pipe can be round or square, and the preferred pipe is square, which can effectively increase the contact area with the heat dissipation machine body 1, thereby achieving a better heat dissipation effect.
[0043] Working principle: A driving device 2 and a conveying chain 3 are provided in the heat sink body 1. The high-temperature mixture enters the first body 11 of the heat sink from the upper right end feed port 14, and is conveyed by the driving device 2 driven by the conveying chain 3. A plurality of scrapers 4 fixed on the ring chain play a driving role, diluting the mixture and flipping it forward, and cooperates with the pulse bag dust collector to effectively remove the dust raised by the high-temperature mixture; in the heat dissipation mechanism 16 under the heat sink body 1, water cooling or air cooling is used to continuously take away the heat released by the high-temperature mixture, which significantly improves the heat dissipation efficiency. At the same time, the dust removal also reduces the pollution emissions to the environment.
[0044] Through the above technical solution, the high-temperature mixture with a temperature of 100-120°C enters the S-shaped multi-return conveying channel from the feed port 14 of the first body 11, and is discharged from the discharge port 15 of the third body 13 after multiple dilution and flipping for 2-5 minutes, so that the final temperature of the mixture drops to below 70°C.
[0045] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
