Description

Technical Field

[0001] This utility model relates to the field of material conveying technology in lime kilns, and in particular to a hoisting hopper for lime kilns. Background Technology

[0002] A lime kiln is an industrial furnace used to calcine raw materials such as limestone at high temperatures to decompose them into lime. During the lime production process, raw materials such as limestone and coke need to be continuously transported to different heights in the lime kiln for calcination. The hoist hopper is an important device specifically designed for vertically lifting and transporting materials into the lime kiln. It is pulled by a hoist and moves up and down along a fixed track to lift the material on the ground to the top of the lime kiln or a designated height before unloading, thus achieving efficient material transportation.

[0003] The existing lime kiln hoist hopper has the following shortcomings:

[0004] Traditional hoppers often require manual assistance to open the discharge port during unloading, which is complex and inefficient, especially when working at heights, posing significant safety hazards. In addition, most hoppers have a fixed discharge height, which cannot meet the feeding requirements of different lime kilns. If the discharge height needs to be changed, additional auxiliary equipment or the entire conveying system needs to be adjusted, which is not only costly but also affects the production schedule. Utility Model Content

[0005] This utility model proposes a hoisting hopper for lime kilns, which simplifies the unloading process and improves unloading safety through an automated unloading structure and an adjustable dropping device, and can flexibly adapt to lime kilns of different heights, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting hopper for a lime kiln, comprising a supporting truss, wherein a lifting hopper is slidably connected to the inner side of the supporting truss, the lifting hopper comprising a hopper, wherein an inclined discharge pipe is fixedly connected to the bottom end of the hopper, and a guiding mechanism is provided on the outer surface of the inclined discharge pipe.

[0007] The material guiding mechanism includes two second motors, which are fixedly connected to the left and right sides of the inclined discharge pipe, respectively. The output shafts of the second motors are fixedly connected to second screws, and the outer surfaces of the second screws are threaded with threaded sliding columns. A U-shaped sliding guide plate is fixedly connected to the opposite faces of the two threaded sliding columns. The U-shaped sliding guide plate is slidably connected to the lower outer surface of the inclined discharge pipe. A U-shaped push plate is fixedly connected to the top of the U-shaped sliding guide plate, and the U-shaped push plate is slidably connected to the top of the inclined discharge pipe. A U-shaped groove that runs vertically through the inside of the U-shaped push plate is provided. Sliding columns are slidably connected to the left and right sides of the inner surface of the U-shaped groove. A rotating push plate is fixedly connected to the bottom of the sliding columns. The rotating push plate is rotatably connected to the upper surface of the inclined discharge pipe. The bottom of the rotating push plate away from the sliding columns extends into the interior of the inclined discharge pipe and is fixedly connected to a rotating baffle.

[0008] Preferably, winches are fixedly connected to the top left and right sides of the support truss, and a cable is fixedly connected to the output end of the winch. The bottom end of the cable passes through the inner side of the support truss and is fixedly connected to the top of the hopper.

[0009] Preferably, the hopper is slidably connected to the inner side of the supporting truss, and two limiting pulleys are provided on the front of both the left and right sides of the hopper.

[0010] Preferably, the inner surface of the supporting truss has limit grooves on both the left and right sides of the front side, and the limit pulley is slidably connected inside the limit groove.

[0011] Preferably, a first motor is fixedly connected to both the left and right sides of the top rear side of the support truss, and the output shaft of the first motor is fixedly connected to a first screw.

[0012] Preferably, the outer surface of the first screw is threadedly connected to a threaded slide plate, and the outer surfaces of the two threaded slide plates are fixedly connected to an inclined U-shaped material drop plate, which is slidably connected to the middle of the rear side of the support truss.

[0013] 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:

[0014] 1. In this utility model, after the hopper is raised to a specified height, the second motor drives the second screw to rotate. Through threaded transmission, the threaded slide column drives the U-shaped sliding guide plate to move to the top of the inclined U-shaped discharge plate. When the U-shaped push plate slides synchronously, the cooperation between the U-shaped groove and the sliding column drives the rotating push plate to rotate, pushing open the rotating baffle. Under the action of gravity, the material slides into the lime kiln along the inclined discharge pipe, the U-shaped sliding guide plate and the inclined U-shaped discharge plate. This structure realizes the automation of the unloading process, eliminating the need for manual high-altitude operation and reducing safety risks. At the same time, the continuous material guiding path design makes unloading smoother and more efficient, greatly improving the convenience of raw material feeding.

[0015] 2. In this utility model, after the first motor is started, the first screw rotates and drives the threaded slide plate to slide along the screw axis, thereby realizing the height adjustment of the inclined U-shaped discharge plate. This design breaks the limitation of the fixed discharge height of the traditional hopper. The position of the discharge plate can be flexibly adjusted according to the feeding height requirements of different lime kilns. No additional auxiliary equipment is required, which reduces the transformation cost and greatly enhances the adaptability of the hopper to different specifications of lime kilns, effectively improving the versatility and production efficiency of the material conveying system.

[0021] 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.

[0022] 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.

[0023] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution: including a support truss 1, a lifting hopper 2 slidably connected to the inner side of the support truss 1, a winch 3 fixedly connected to the top left and right sides of the support truss 1, a cable 4 fixedly connected to the output end of the winch 3, the bottom end of the cable 4 passing through the inner side of the support truss 1 and fixedly connected to the top of the hopper 21, a first motor 5 fixedly connected to the top rear left and right sides of the support truss 1, a first screw 6 fixedly connected to the output shaft of the first motor 5, a threaded sliding plate 7 threadedly connected to the outer surface of the first screw 6, and an inclined U-shaped dropping plate 8 fixedly connected to the opposite outer surfaces of the two threaded sliding plates 7, the inclined U-shaped dropping plate 8 slidably connected to the middle of the rear side of the support truss 1;

[0024] The effect achieved by the entire embodiment 1 is as follows: by starting the winch 3, the winch 3 winds up the cable 4, and the cable 4 pulls the hopper 21, so that the lifting bucket 2 can slide up and down along the inner side of the supporting truss 1 to realize the vertical lifting and transportation of materials. At the same time, the first motor 5 is started, and the first motor 5 drives the first screw 6 to rotate. Since the threaded slide plate 7 is threadedly connected to the first screw 6, under the action of threaded transmission, the threaded slide plate 7 slides along the axis of the first screw 6, thereby driving the inclined U-shaped dropping plate 8 to move up and down, realizing the flexible adjustment of the height of the inclined U-shaped dropping plate 8 to adapt to the different heights of the lime kiln feed inlet and meet the material feeding needs of various specifications of lime kilns.

[0025] Example 2: As Figure 3 and Figure 4As shown, this utility model provides a technical solution: the lifting hopper 2 includes a hopper 21, which is slidably connected to the inner side of the supporting truss 1. Two limiting pulleys 22 are provided on the front of both the left and right sides of the hopper 21. Limiting grooves 11 are provided on the left and right sides of the front of the inner surface of the supporting truss 1. The limiting pulleys 22 are slidably connected inside the limiting grooves 11. An inclined discharge pipe 23 is fixedly connected to the bottom end of the hopper 21. A guiding mechanism 24 is provided on the outer surface of the inclined discharge pipe 23. The guiding mechanism 24 includes two second motors 241, which are respectively fixedly connected to the left and right sides of the inclined discharge pipe 23. A second screw 242 is fixedly connected to the output shaft of the second motor 241. A threaded sliding column 24 is threadedly connected to the outer surface of the second screw 242. 3. A U-shaped sliding guide plate 244 is fixedly connected to the opposite face of two threaded sliding columns 243. The U-shaped sliding guide plate 244 is slidably connected to the lower outer surface of the inclined discharge pipe 23. A U-shaped push plate 245 is fixed to the top of the U-shaped sliding guide plate 244. The U-shaped push plate 245 is slidably connected to the top of the inclined discharge pipe 23. A U-shaped sliding groove 246 is opened inside the U-shaped push plate 245, which runs vertically through the inside. Sliding columns 247 are slidably connected to the left and right sides of the inner surface of the U-shaped sliding groove 246. A rotating push plate 248 is fixedly connected to the bottom of the sliding column 247. The rotating push plate 248 is rotatably connected to the upper surface of the inclined discharge pipe 23. The bottom of the rotating push plate 248 away from the sliding column 247 extends into the interior of the inclined discharge pipe 23 and is fixedly connected to a rotating baffle 249.

[0026] The overall effect achieved in Embodiment 2 is as follows: When the lifting hopper 2 is pulled to the corresponding height of the lime kiln feed inlet by the winch 3, the second motor 241 is started. The second motor 241 drives the second screw 242 to rotate. Under the threaded transmission of the second screw 242, the threaded sliding column 243 drives the U-shaped sliding guide plate 244 to slide obliquely towards the U-shaped dropping plate 8. When the U-shaped sliding guide plate 244 slides, the U-shaped push plate 245 slides synchronously. The U-shaped groove 246 inside the U-shaped push plate 245 cooperates with the sliding column 247, and with the U-shaped push... The sliding of plate 245 pushes the sliding column 247 to move, which in turn drives the rotating push plate 248 to rotate around the rotating connection point with the inclined discharge pipe 23. When the rotating push plate 248 rotates, it pushes open the rotating baffle 249 and opens the discharge channel of the inclined discharge pipe 23. At this time, the material in the hopper 21, under the action of gravity, slides smoothly into the lime kiln along the inclined discharge pipe 23, the U-shaped sliding guide plate 244 and the inclined U-shaped drop plate 8, realizing automated unloading. There is no need for manual climbing to a high place to operate the unloading port, which improves the safety and efficiency of unloading.

[0027] The working principle of the entire equipment is as follows: First, based on the height of the lime kiln feed inlet, the first motor 5 is started. The first motor 5 drives the first screw 6 to rotate. The threaded slide plate 7, under threaded transmission, drives the inclined U-shaped material drop plate 8 to move up and down along the rear side of the support truss 1, adjusting the inclined U-shaped material drop plate 8 to a suitable height. Next, the material is loaded into the hopper 21. The winch 3 is started, and the winch 3 winds up the cable 4, which pulls the hopper 21. The limiting pulleys 22 on both sides of the hopper 21 slide in the limiting grooves 11 on the inner surface of the support truss 1, ensuring that the lifting bucket 2 rises smoothly along the fixed track. When the lifting bucket 2 reaches the corresponding height of the lime kiln feed inlet, the second motor 241 is started. The second motor 241 drives the second screw 242 to rotate, and the threaded slide column 243 drives the U-shaped sliding guide plate 244 to slide towards the inclined U-shaped dropping plate 8. At the same time, the U-shaped push plate 245 drives the rotating push plate 248 to rotate through the cooperation of the U-shaped slide groove 246 and the sliding column 247, pushing open the rotating baffle 249 and opening the unloading channel. Under the action of gravity, the material in the hopper 21 passes through the inclined discharge pipe 23, the U-shaped sliding guide plate 244 and the inclined U-shaped dropping plate 8 in sequence, and falls into the lime kiln to complete the unloading. After the unloading is completed, the second motor 241 is started in reverse to reset the rotating baffle 249 and close the unloading channel. Then the winch 3 is started to lower the lifting hopper 2 to start the next loading and transportation cycle.

[0028] 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.
