Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, and more specifically, to an automatic feeding device for rotary kilns. Background Technology

[0002] A rotary kiln is a type of kiln that rotates to calcine (commonly known as a rotary kiln), belonging to the category of building materials equipment. Rotary kilns can be classified according to the materials they process: cement kilns, metallurgical and chemical kilns, and lime kilns.

[0003] Chinese patent CN113847808U discloses a utility model patent for "a rotary kiln material feeding device". In this patent, a drive cylinder is activated, causing a pusher plate to move towards the feed inlet, thus pushing the material from the feed inlet into the rotary kiln. After the pusher plate pushes the material from the feed inlet into the rotary kiln, the drive cylinder retracts the pusher plate, allowing the material to fall through the hopper into the receiving cavity and be positioned in front of the pusher plate. However, in this utility model, as the pusher plate moves forward, the distance between the pusher plate and the receiving cavity decreases, which can easily lead to material blockage between the pusher plate and the receiving cavity, causing jamming. Furthermore, this utility model cannot achieve continuous feeding, affecting the production efficiency of the rotary kiln. This is a deficiency of the existing technology. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0018] like Figure 1-3 As shown, an automatic feeding device for a rotary kiln includes a base 1, on which a rotary kiln body 9 is mounted. One end of the rotary kiln body 9 has a feed inlet 91, and a discharge hopper 2 is located on one side of the feed inlet 91. The side wall 22 of the discharge hopper 2 has a discharge port 21, which is directly opposite the feed inlet 91. In this invention, the discharge port 21 perfectly aligns with the feed inlet 91 of the rotary kiln body, ensuring that materials can accurately enter the rotary kiln body 9.

[0019] The hopper 2 is equipped with an anti-blocking mechanism 3, which includes an anti-blocking component 31. The anti-blocking component 31 is inclined from top to bottom towards the feed inlet 21, with one end suspended and the other end fixed to the side wall 22 of the hopper 2. During the falling process, the material falls onto the anti-blocking component 31, and under the action of gravity, the material can smoothly slide down along the anti-blocking component 31, effectively preventing the material from accumulating and blocking at the feed inlet 21.

[0020] To further facilitate material feeding, a vibrating motor 4 is installed at the bottom of the feeding hopper 2. The vibrating motor 4 generates vibration to further prevent material blockage during the feeding process. The vibration not only helps the material flow but also clears blockages through physical vibration when they occur.

[0021] Furthermore, the anti-clogging component includes a set of anti-clogging rods 311 arranged side by side. One end of each anti-clogging rod 311 is fixed to a connecting rod 32, and the other end of the connecting rod 32 is fixed to a moving rod 33. The other end of the moving rod 33 passes through the side wall of the hopper 2 and is fixed to a mounting plate 34, which is also fixed to the side wall of the hopper 2. These anti-clogging rods are mutually fixed through the connecting rods 32, forming an integral structure. This ensures structural stability and provides multiple channels for material to flow, further reducing the possibility of blockage.

[0022] Furthermore, an adjustment mechanism is provided between the mounting plate 34 and the side wall of the hopper 2. The adjustment mechanism includes a sleeve 54 and an adjusting rod 51. One end of the sleeve 54 is fixed to the mounting plate 34, and the other end of the sleeve 54 is fitted over the adjusting rod 51. The other end of the adjusting rod 51 is fixed to the side wall of the hopper 2. A fixing bolt 53 is provided on the sleeve 54, and a bolt hole 52 is provided on the adjusting rod 51 to cooperate with the fixing bolt 53. According to actual needs, by adjusting the position of the fixing bolt 53 on the adjusting rod 51, the position of the anti-clogging component in the hopper 2 can be easily adjusted, thereby optimizing the material flow effect.

[0023] Furthermore, a support 6 is provided at the bottom of the hopper 2, and the support 6 is installed on the base 1 to provide stable support for the entire feeding device.

[0024] Furthermore, a gear ring 7 is fixed to the outside of the rotary kiln body 9, and a gear 8 is provided on the base 1. The gear 8 meshes with the gear ring 7, enabling the rotary kiln to rotate in a stable and controllable manner, further improving the efficiency of feeding and material handling.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
