Description

Technical Field

[0001] This utility model belongs to the technical field of limestone processing equipment, and in particular relates to a device for preventing deviation of a rotary kiln chain conveyor. Background Technology

[0002] In limestone processing, the rotary kiln chain conveyor plays a crucial role in stably transporting limestone raw materials to the rotary kiln for subsequent processing such as calcination. However, the chain conveyor's misalignment problem is particularly prominent under limestone processing conditions. Limestone is hard, and the impact force on the chain conveyor during transportation is significant. After being subjected to such impact forces for a long time, the various components of the chain conveyor are prone to wear and deformation, leading to a gradual loss of manufacturing and installation precision, which in turn causes the chain to misalign.

[0003] A Chinese patent with publication number CN221458869U discloses an anti-deviation device for chain conveyors. By setting up the anti-deviation component, the chain plates can be clamped and centered by the rollers on both sides during the operation of the chain conveyor body, preventing the chain plates from deviating during operation. The rollers can adjust the corresponding position according to the tension of the chain plates, and work with the tail wheel rotation shaft to adjust the tension of the chain in the chain plates, further preventing the chain plates from deviating. This achieves the purpose of clamping the chain plates and reducing the occurrence of chain plate deviation.

[0004] However, in the process of conveying limestone materials, the irregular shape of limestone makes it difficult to distribute it evenly when it accumulates on the chain plate. This results in uneven stress on the chain plate during operation, which is one of the important factors causing the chain plate machine to deviate. Once the chain plate machine deviates, it will not only cause the limestone material to spill, increasing material loss and cleaning costs, but also significantly shorten the service life of the chain plate machine. Utility Model Content

[0005] The purpose of this utility model is to provide a device to prevent deviation of a rotary kiln chain conveyor. By cooperating with the correction mechanism and the material distribution mechanism, it solves the problem in the prior art where it is difficult to distribute the limestone material evenly when it is being transported on the chain conveyor. This causes uneven force on the chain conveyor during operation, resulting in deviation of the chain conveyor.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an anti-deviation device for a rotary kiln chain conveyor, comprising a frame, an inner cavity of which is equipped with a chain conveyor belt, a drive motor fixedly connected to one side of the frame surface, the output end of the drive motor being fixedly connected to the conveyor shaft of the chain conveyor belt, correction mechanisms fixedly connected to the front and rear ends of the frame, and a material feeding mechanism fixedly connected to one side of the top of the frame. The correction mechanism includes a mounting plate, one side of which is fixedly connected to the frame, a threaded rod threadedly connected to the inner cavity of the mounting plate, one side of which is movably connected to the frame via a bearing, a threaded sleeve threadedly connected to the surface of the threaded rod, and movable blocks fixedly connected to the top and bottom of the threaded sleeve. A connecting column is fixedly connected to one side of the moving block. The side of the connecting column away from the moving block extends into the inner cavity of the frame. A protective cover is fixedly connected to one side of the connecting column. The inner cavity of the protective cover is movably connected to a limit wheel via a rotating shaft. By distributing correction mechanisms on both sides of the frame, the chain conveyor belt can be corrected according to the offset position by selecting the correction mechanism on each side. The chain conveyor belt can be easily and quickly adjusted by the operator through manual adjustment. Limit wheels are set on both sides of the chain conveyor belt. When deviation occurs, the position of the chain conveyor belt is limited by the adjustable limit wheels, thereby improving the stability of the chain conveyor belt during operation.

[0008] The present invention is further configured such that the material feeding mechanism includes a fixed column, a fixed frame is fixedly connected to the top of the fixed column, a motor is fixedly connected to one side of the surface of the fixed frame, a rotating rod is fixedly connected to the output end of the motor, one side of the rotating rod extends into the inner cavity of the fixed frame, cams are fixedly connected to the front and rear ends of the rotating rod, a vibrating plate is movably connected to the top of the fixed frame via a movable shaft, and the top of the cam contacts the vibrating plate. The material feeding mechanism, through high-frequency vibration, enables the limestone raw material to be evenly dispersed before entering the chain plate. This effectively avoids the local accumulation or concentrated distribution of material on the chain plate, making the pressure on the chain plate more uniform during operation. The stable and uniform material distribution reduces the risk of twisting and deformation of the chain plate due to uneven force, fundamentally improving the stability of the chain plate machine operation and further ensuring the reliable operation of the equipment.

[0009] The present invention is further configured such that a spring is fixedly connected to one side of the bottom of the vibrating plate, and there are two springs. The bottom of the spring is fixedly connected to the fixing frame, the top of the spring contacts the vibrating plate, and the bottom of the spring is connected to the fixing frame. This can support the vibrating plate while improving the vibration effect of the vibrating plate.

[0010] The present invention is further configured such that a handwheel is fixedly connected to the surface of the threaded rod, and the surface of the handwheel is provided with anti-slip texture. Rotating the handwheel drives the threaded rod to rotate, which facilitates the staff to perform correction processing on the device.

[0011] The present invention is further configured such that the number of limiting wheels is four, and the four limiting wheels are equidistant from each other. The limiting wheels are made of steel, and one side of the limiting wheel contacts both sides of the chain conveyor belt. The use of steel can effectively limit the chain conveyor belt and improve the anti-deviation effect.

[0012] The present invention is further configured such that a guide plate is fixedly connected to one side of the fixed frame, and one side of the guide plate extends above the chain conveyor belt. The guide plate can uniformly discharge the material on the vibrating plate, thereby improving the material discharge efficiency.

[0013] The present invention is further configured such that support columns are fixedly connected to the four corners of the bottom of the frame, and pads are fixedly connected to the bottom of the support columns. The support columns and pads support the frame and ensure the stability of the overall structure of the device.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model sets up a correction mechanism on both sides of the chain conveyor belt, and ensures that the chain conveyor belt can stably transport materials by manual adjustment. By rotating the threaded rod, the threaded rod drives the threaded sleeve to move, the threaded sleeve drives the moving block to move, the moving block drives the connecting column to move, and the connecting column drives the limit wheel inside the protective cover to move, so that the limit wheel contacts the edge of the chain conveyor belt, thereby applying lateral force to the chain in a timely and effective manner, so that it returns to the normal operating track, and can adapt to different degrees of impact force.

[0016] 2. This utility model sets up a material distribution mechanism at the feed inlet of the chain conveyor. The material distribution mechanism consists of a motor, a cam and a vibrating plate. The vibrating plate receives the material entering from the feed inlet and distributes it evenly in the width direction of the chain plate. The motor drives the cam to rotate, and the cam generates high-frequency vibration on the vibrating plate, which further promotes the even distribution of the material and avoids the material from accumulating on one side of the chain plate, thereby reducing the deviation caused by uneven material distribution.

This timely and effective application of lateral force to the chain conveyor returns it to its normal operating track. It can adapt to different levels of impact force. The vibrating plate 506 receives the material entering from the feed port and distributes it evenly in the width direction of the chain plate. The motor 503 rotates the rod 504, which drives the cam 505 to rotate. The cam 505 generates high-frequency vibration on the vibrating plate 506.
