Description

Technical Field

[0001] This utility model relates to the field of lime kiln ash unloading technology, and in particular to a lime kiln ash unloading adjustment device. Background Technology

[0002] Lime unloading from a lime kiln is a crucial step in the lime production process, directly affecting production efficiency, equipment lifespan, and environmental indicators. The unloading speed must be matched with the calcination speed to avoid ash and slag accumulation that could lead to abnormal pressure inside the kiln.

[0003] As disclosed in announcement number CN221302003U, a lime kiln ash discharge speed and flow rate control device belongs to the field of flow rate control devices. It includes a discharge hopper with a control mechanism movably installed on it. The control mechanism comprises a control box, a control pipe, a discharge port, a mounting plate, a slide rod, a first screw, a control plate, a rotating rod, and a spiral blade. The control box is fixedly connected to the side of the discharge hopper, the control pipe is fixedly connected to the bottom of the discharge hopper, the discharge port is fixedly installed on the bottom surface of the control pipe, and the mounting plate is fixedly installed on the bottom surface of the control box. The control plate is movably installed inside the control box. Through the control mechanism, a first stepper motor rotates a first screw, causing the control plate to move within the control box, controlling the size of the discharge hopper's outlet. The spiral blade is rotated by a second stepper motor, pushing dust out of the discharge port, thus adjusting the dust discharge speed. This makes the lime kiln ash discharge speed and flow rate easier to control, and ash discharge more convenient.

[0004] This patent can achieve the purpose of adjusting the discharge speed of dust. However, the existing structure requires the screw to rotate to control the extension and retraction of the adjustment plate. If the dust on the surface is not cleaned when the adjustment plate retracts, dust will easily accumulate in the gap between the adjustment plate and the discharge hopper, causing the adjustment plate to jam and affecting the accuracy. Furthermore, when a lot of dust is adsorbed on the surface of the screw, it will affect the accuracy of its rotation, thus affecting normal use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when the adjustment plate is extended or retracted, it needs to be adjusted by the screw rotation. If the dust on the surface of the adjustment plate is not cleaned when it retracts, dust will easily accumulate in the gap between the adjustment plate and the discharge hopper, causing the adjustment plate to jam and affecting the accuracy. Furthermore, when a lot of dust is adsorbed on the surface of the screw, it will affect the accuracy of its rotation, thus affecting normal use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lime kiln ash discharge regulating device, comprising a device body, a discharge hopper provided on the top of one side of the device body, a discharge port provided on the bottom of the other side of the device body, an regulating component provided near the discharge hopper on the device body, the regulating component comprising a fixed frame, two sets of electric push rods connected to the rear end of the fixed frame, an regulating plate connected to the output end of the two sets of electric push rods, a connecting block connected to the top of the fixed frame, four sets of springs connected inside the connecting block, a push plate connected to the bottom of each of the four sets of springs, and a rubber scraper connected to the bottom of the push plate.

[0007] Furthermore, the two sets of electric push rods are controlled by the same set of control switches, and the size of the adjusting plate is matched with the size of the discharge hopper.

[0008] Furthermore, the push plate and the spring form an elastic structure, and the bottom surface of the rubber scraper is in contact with the top of the adjusting plate.

[0009] Furthermore, a waste heat recovery component is connected to the bottom of the main body of the device near the discharge port. The waste heat recovery component includes a water tank, and an air pipe is installed inside the water tank.

[0010] Furthermore, the water tank has an inlet connected to the front end and an outlet connected to the bottom.

[0011] Furthermore, a filter box is connected to one side surface of the trachea, and magnetic blocks are provided on the inner walls of both the upper and lower ends of the filter box.

[0012] Furthermore, the filter box is equipped with a filter screen inside, and magnets are connected to both the upper and lower surfaces of the filter screen, forming a magnetic connection between the magnets and the magnetic block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when adjusting the size of the discharge hopper, the adjusting plate can be extended and retracted by pushing the electric push rod. When retracting, the adjusting plate will be cleaned by the rubber scraper before retracting into the fixed frame, which avoids the problem of dust accumulation in the gap between the adjusting plate and the discharge hopper, which would cause the adjusting plate to jam and affect the accuracy, thus ensuring the stability of ash discharge.

[0015] 2. In this utility model, the gas pipe can use the residual heat during ash unloading to heat the water in the water tank, thereby achieving the purpose of waste heat recovery, avoiding heat waste, and improving the practicality of the main body of the device. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] Example 1, such as Figure 1 - Figure 3As shown, this utility model provides a lime kiln ash discharge adjustment device, including a device body 1. A discharge hopper 2 is provided on the top of one side of the device body 1, and a discharge port 3 is provided on the bottom of the other side of the device body 1. An adjustment component 4 is provided near the discharge hopper 2 on the device body 1. The adjustment component 4 includes a fixing frame 401. Two sets of electric push rods 402 are connected to the rear end of the fixing frame 401. An adjustment plate 403 is connected to the output end of the two sets of electric push rods 402. A connecting block 404 is connected to the top of the fixing frame 401. Four sets of springs 405 are connected inside the connecting block 404. Push plates 406 are connected to the bottom of each of the four sets of springs 405. A rubber scraper 407 is connected to the bottom of the push plate 406. The two sets of electric push rods 402 are the same set of control switches. The size of the adjustment plate 403 matches the size of the discharge hopper 2. An elastic structure is formed between the push plate 406 and the spring 405. The bottom surface of the rubber scraper 407 is in contact with the top of the adjustment plate 403.

[0025] The effect achieved in Embodiment 1 is as follows: When it is necessary to adjust the flow rate of the discharge hopper 2, the electric push rod 402 can be turned on by the control switch, so that the electric push rod 402 can push the adjusting plate 403 to move forward, and the flow rate can be adjusted through the adjusting plate 403. When the adjusting plate 403 retracts through the electric push rod 402, the dust adsorbed on the surface of the adjusting plate 403 will also be cleaned by the rubber scraper 407. Under the push of the spring 405, the rubber scraper 407 will stick tightly to the surface of the adjusting plate 403, improve the cleaning effect, avoid the problem that the adjusting plate 403 is easy to accumulate dust in the gap between the adjusting plate 403 and the discharge hopper 2, which would cause the adjusting plate 403 to get stuck and affect the accuracy, thus ensuring the stability during ash discharge.

[0026] Example 2, as Figure 4 and Figure 5 As shown, a waste heat recovery component 5 is connected to the bottom of the main body 1 near the discharge port 3. The waste heat recovery component 5 includes a water tank 501, an air pipe 502 is installed inside the water tank 501, an inlet 503 is connected to the front end of the water tank 501, and an outlet 504 is connected to the bottom of the water tank 501. A filter box 505 is connected to one side surface of the air pipe 502. Magnetic blocks 506 are installed on the inner walls of both the upper and lower ends of the filter box 505. A filter screen 507 is installed inside the filter box 505. Magnets 508 are connected to both the upper and lower surfaces of the filter screen 507. The magnets 508 and the magnetic blocks 506 form a magnetic connection.

[0027] The effect achieved in Embodiment 2 is as follows: the air pipe 502 is connected to the discharge hopper 2. When ash is being discharged, high-temperature air will enter the air pipe 502 and heat the water in the water tank 501 through the air pipe 502. The filter screen 507 in the filter box 505 can achieve the effect of filtering dust and prevent the air pipe 502 from being blocked. At the same time, the filter screen 507 is magnetically fixed by the filter screen 507 and the magnet 508, which is very convenient for disassembly and cleaning. Thus, the purpose of waste heat recovery is achieved, heat waste is avoided, and the practicality of the main body 1 of the device is improved.

[0028] Working principle: When adjusting the size of the discharge hopper 2, the adjusting plate 403 can be extended or retracted by the electric push rod 402. When retracting, the adjusting plate 403 will be cleaned by the rubber scraper 407 before retracting into the fixed frame 401. This avoids dust accumulation in the gap between the adjusting plate 403 and the discharge hopper, which could cause the adjusting plate 403 to get stuck and affect the accuracy. This ensures the stability of ash discharge. The air pipe 502 can use the residual heat during ash discharge to heat the water in the water tank 501, thereby achieving the purpose of waste heat recovery, avoiding heat waste and improving the practicality of the main body 1 of the device.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
