Description

Technical Field

[0001] This utility model relates to the field of gypsum-based acid production technology, and in particular to a high-efficiency cooling and conveying device for clinker in a gypsum-based acid grate cooler. Background Technology

[0002] The gypsum acid production grate cooler is a key piece of equipment in the gypsum acid production process. It is mainly used to cool the high-temperature clinker produced after gypsum calcination. In the gypsum acid production process, gypsum is calcined to produce clinker containing sulfur dioxide and other components. The temperature of these clinker is extremely high, usually between 800-1000℃, and they need to be cooled quickly by the grate cooler so that the clinker can be crushed, conveyed and further chemically reacted to extract sulfuric acid and other products.

[0003] The clinker cooling and conveying device is an important auxiliary equipment that works in conjunction with the grate cooler. Its function is to transport the clinker cooled by the grate cooler to the next production process in a timely and efficient manner. It not only has to undertake the conveying function, but also needs to ensure the stable cooling effect of the clinker during the conveying process to avoid the impact of temperature rise on subsequent production processes.

[0004] The existing high-efficiency cooling and conveying device for clinker in a gypsum acid grate cooler has the following shortcomings:

[0005] Because of the low efficiency of the cooling air circulation, the heat exchange between the cold air and the clinker is insufficient, resulting in a slow cooling rate of the clinker. Some clinker still has the problem of excessively high temperature at the end of the conveying process. At the same time, the existing equipment cannot adjust the spacing according to the clinker particle size because the baffle fixing method of the conveyor belt is inflexible, and the baffle is easy to loosen and fall off, which affects the stability of the conveying process. Utility Model Content

[0006] This invention proposes a high-efficiency cooling and conveying device for clinker in a gypsum acid grate cooler. It improves the cooling effect by enhancing the cooling air circulation efficiency and optimizes the baffle fixing structure to improve the conveying stability, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency cooling and conveying device for clinker of gypsum acid grate cooler, comprising a cooling and conveying cabinet, wherein a conveyor belt assembly is provided in the middle of the cooling and conveying cabinet, and a cooling component is fixedly connected to the bottom of the interior of the cooling and conveying cabinet.

[0008] The cooling assembly includes a heat exhaust pipe, which is fixedly connected to the bottom of the inner surface of the cooling conveying cabinet. Several cooling air boxes are fixedly connected to the top of the heat exhaust pipe. An exhaust pipe is fixedly connected to the center of the top of the cooling air box. A dustproof net is fixedly connected to the top of the inner surface of the exhaust pipe. Air supply pipes are fixedly connected to both the front and rear sides of the cooling air box. The top of the air supply pipe extends to the upper interior of the cooling conveying cabinet and is fixedly connected to an air outlet nozzle.

[0011] Preferably, the outer surface of the conveyor belt assembly has a plurality of through-hole heat dissipation holes, and a plurality of strip baffles are fixedly connected to the outer surface of the conveyor belt assembly.

[0012] Preferably, the strip baffle is rotatably connected to fastening bolts on both the front and rear sides of the side away from the conveyor belt assembly. The fastening bolts penetrate to the side of the strip baffle close to the conveyor belt assembly and have tapered locking blocks threaded on their outer surfaces. The tapered locking blocks are slidably engaged with the inner side of the heat dissipation holes.

[0013] Preferably, the left and right ends of the heat exhaust pipe extend to the left and right sides of the outer surface of the cooling conveying cabinet, respectively, and dustproof nets are fixedly connected to the left and right sides of the inner surface of the heat exhaust pipe.

[0014] Preferably, a support frame is fixedly connected to both the left and right sides of the inner surface of the heat exhaust pipe, a motor is fixedly connected to the middle of the support frame, and a guide fan is fixedly connected to the output shaft of the motor.

[0015] Preferably, metal heat-conducting plates are fixedly connected to both the front and rear sides of the inner surface of the cooling box, and the bottom end of the metal heat-conducting plate extends through to the inner surface of the heat exhaust pipe.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. In this utility model, the cooling assembly forms a circulating air path through a cooling air box, air supply pipe, air outlet nozzle, and exhaust pipe.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: including a cooling conveyor cabinet 1, a conveyor belt assembly 2 is provided in the middle of the cooling conveyor cabinet 1, a cooling assembly 3 is fixedly connected to the bottom of the interior of the cooling conveyor cabinet 1, an inlet 11 is provided on the upper left side of the cooling conveyor cabinet 1, an outlet 12 is provided on the upper right side of the cooling conveyor cabinet 1, the left side of the conveyor belt assembly 2 is located at the bottom of the inlet 11, the right side of the conveyor belt assembly 2 extends to the outside of the right side of the outlet 12, a plurality of heat dissipation holes 21 are provided on the outer surface of the conveyor belt assembly 2, a plurality of strip baffles 22 are fixedly connected to the outer surface of the conveyor belt assembly 2, fastening bolts 221 are rotatably connected to both the front and rear sides of the side of the strip baffles away from the conveyor belt assembly 2, the fastening bolts 221 extend to the side of the strip baffles 22 close to the conveyor belt assembly 2 and a conical block 222 is threadedly connected to the outer surface, the conical block 222 is slidably engaged with the inner side of the heat dissipation hole 21;

[0030] The overall effect of Embodiment 1 is as follows: stable conveying of clinker and flexible adjustment of baffles are achieved. High-temperature clinker falls from the feed inlet 11 onto the conveyor belt assembly 2 and moves towards the discharge outlet 12 under the operation of the conveyor belt. The strip baffle 22 can effectively prevent the clinker from sliding and accumulating, ensuring that the conveying process proceeds in an orderly manner. By rotating the fastening bolt 221, the conical block 222 can be driven to slide in the heat dissipation hole 21. This can not only adjust the tightness of the strip baffle 22 to prevent loosening and falling off, but also change the baffle spacing by selecting different positions of the heat dissipation hole 21 according to the clinker particle size, thus improving the adaptability of the device to clinker of different specifications. At the same time, the heat dissipation hole 21 can also allow the cooling air to pass smoothly through the conveyor belt and contact the clinker, providing favorable conditions for the cooling process.

[0031] Example 2: As Figure 4 and Figure 5As shown, this utility model provides a technical solution: the cooling assembly 3 includes a heat exhaust pipe 31, which is fixedly connected to the bottom of the inner surface of the cooling conveying cabinet 1. Several cooling air boxes 33 are fixedly connected to the top of the heat exhaust pipe 31. An exhaust pipe 34 is fixedly connected to the center of the top of each cooling air box 33. A second dustproof net 35 is fixedly connected to the top of the inner surface of the exhaust pipe 34. Air supply pipes 36 are fixedly connected to both the front and rear sides of the cooling air box 33. The top of each air supply pipe 36 extends to the upper interior of the cooling conveying cabinet 1 and is fixedly connected to an air outlet nozzle 37. The left and right ends of the heat exhaust pipe 31 penetrate to the left and right sides of the outer surface of the cooling conveying cabinet 1, respectively. A first dustproof net 32 ​​is fixedly connected to both the left and right sides of the inner surface of the heat exhaust pipe 31. Support frame 311 is fixedly connected to both the left and right sides of the inner surface. Motor 312 is fixedly connected to the middle of support frame 311. Fan 313 is fixedly connected to the output shaft of motor 312. Metal heat-conducting plate 331 is fixedly connected to both the front and rear sides of the inner surface of the cooling air box 33. The bottom end of metal heat-conducting plate 331 extends through to the inner surface of heat exhaust pipe 31. Semiconductor heat exchanger 332 is fixedly connected to the middle of the lower surface of the inner wall of the cooling air box 33. The bottom end of semiconductor heat exchanger 332 extends through to the interior of heat exhaust pipe 31. Support frame 333 is fixedly connected to the middle of the upper surface of the inner wall of the cooling air box 33. Motor 334 is fixedly connected to the middle of support frame 333. Fan 335 is fixedly connected to the output shaft of motor 334.

[0032] The overall effect of Embodiment 2 is as follows: a highly efficient cooling air circulation system is constructed, significantly improving the clinker cooling efficiency. Motor 2 334 drives guide fan 2 335 to rotate, causing the cold air in the cooling air box 33 to be blown from the air outlet nozzle 37 through the air supply pipe 36 to the clinker on the conveyor belt assembly 2, achieving initial heat exchange. The hot air after heat exchange flows back to the cooling air box 33 under the action of the exhaust pipe 34. The metal heat-conducting plate 331 and the semiconductor heat exchanger 332 quickly transfer the heat carried by the hot air to the heat exhaust pipe 31. Motor 1 312 drives guide fan 1 313 to operate, accelerating the airflow in the heat exhaust pipe 31 and timely discharging heat outside the cabinet. Dustproof net 1 32 and dustproof net 2 35 prevent clinker particles from entering the cooling assembly and causing blockage, ensuring the long-term stable operation of the cooling system.

[0033] The working principle of the entire equipment is as follows: After the equipment is started, the high-temperature clinker is discharged from the gypsum acid grate cooler and falls onto the conveyor belt assembly 2 through the feed inlet 11 of the cooling conveyor cabinet 1. The conveyor belt assembly 2 operates at a stable speed, driving the clinker to move towards the discharge outlet 12 along the conveying direction. During this period, the strip baffle 22 moves synchronously with the conveyor belt, and prevents the clinker from sliding or accumulating due to inertia through physical blocking. The operator can adjust the engagement depth of the conical block 222 in the heat dissipation hole 21 by rotating the fastening bolt 221 according to the real-time clinker particle size. This ensures that the baffle is firmly fixed and allows for flexible adjustment of the spacing between adjacent baffles to adapt to the material specifications.

[0034] The cooling component 3 starts synchronously with the conveying process. The second motor 334 drives the second guide fan 335 to rotate at high speed, creating a negative pressure inside the cooling air box 33. This allows air to enter the cooling air box 33 from the exhaust pipe 34 for cooling. The cold air is pressurized by the air supply pipe 36 and then blown obliquely towards the clinker surface from the air outlet nozzle 37. Some of the cold air directly contacts the clinker surface for heat exchange, while the other part passes through the heat dissipation hole 21 and contacts the bottom of the clinker, achieving all-round heat exchange. The hot air that has absorbed heat flows back to the cooling air box 33 under the continuous suction of the exhaust pipe 34. At this time, the metal heat-conducting plate 331 quickly absorbs the heat of the hot air through heat conduction, while the semiconductor heat exchanger 332 enhances heat transfer through the thermoelectric power generation principle. Together, they transfer the heat to the heat exhaust pipe 31.

[0035] The motor 312 inside the heat dissipation pipe 31 drives the guide fan 313 to rotate in opposite directions. The left guide fan exhausts air to the outside of the cabinet, while the right guide fan draws in cold air from the outside, forming a directional airflow that quickly carries the heat out of the cabinet. After being cooled, the air in the cooling air box 33 is sent back into the air supply pipe 36 by the guide fan 335 to complete the cold air circulation.

[0036] After continuous conveying and multiple rounds of air circulation heat exchange, the clinker temperature is effectively reduced, and it is finally discharged from the discharge port 12 to enter the subsequent crushing process.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
