Description

Technical Field

[0001] This utility model relates to the field of incineration feeding technology, and in particular to a feeding device for improving the incineration stability of rotary kilns. Background Technology

[0002] Rotary kiln combustion stability feed is a material supply method used in rotary kilns to ensure a stable supply and uniform distribution of materials, thereby improving the combustion efficiency and stability of the rotary kiln.

[0003] The feeding of materials for stable combustion in existing rotary kilns typically relies on manual tipping. This manual tipping requires extensive manual labor, is physically demanding, and is particularly difficult in high-temperature, complex, or harsh environments. Operators must constantly monitor the material supply and flow to ensure there is neither too much nor too little. However, due to variations in the operating environment and materials, manual operation struggles to guarantee a precise feeding rate. Furthermore, manual operation is limited by factors such as operator skill level and environmental conditions, making it difficult to achieve a uniform and stable material supply. During manual tipping, factors such as material flow rate, tipping angle, and tipping duration are difficult to control precisely, leading to significant differences in the amount of material fed at different locations and times. This uneven feeding affects the temperature stability within the rotary kiln and can even impact the combustion process. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a feeding device to improve the combustion stability of rotary kiln. The device controls the reciprocating motion of the pushing mechanism through the drive mechanism, completely eliminating the need for manual operation, reducing labor intensity, and making the entire feeding process more automated and improving work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a feeding device for improving the combustion stability of a rotary kiln, comprising a rotary kiln body, three sets of support legs evenly arranged at the bottom end of the rotary kiln body, a feeding chamber provided on the side wall of the rotary kiln body, a pushing mechanism slidably connected in the feeding chamber, a driving mechanism installed on the side wall of the feeding chamber, the driving mechanism being connected to the pushing mechanism, the driving mechanism driving the pushing mechanism to reciprocate, and the pushing mechanism pushing the material in the feeding chamber into the rotary kiln body for combustion.

[0006] As a preferred embodiment of this utility model, the feeding mechanism includes slide rails symmetrically arranged on the outer walls of both sides of the feeding chamber, rollers rotatably connected in the slide rails, a connecting rod rotatably connected to the rollers at one end, a push plate connected to the other end of the connecting rod, and a push rod connected to the outer wall of the push plate.

[0007] As a preferred embodiment of this utility model, the push plate is rectangular in shape, and a rubber pad is glued to the outer wall of the push plate.

[0008] As a preferred embodiment of this utility model, the push plate and the push rod are detachably connected by bolts, and the outer end of the push rod extends to the outside of the feeding chamber and is connected to the drive mechanism.

[0009] As a preferred technical solution of this utility model, the driving mechanism includes an auxiliary frame installed on the outer wall of the feeding chamber, a rotating column rotatably connected to the inner wall of the auxiliary frame, a slot opened on the outer wall of the rotating column, a movable rod with one end inserted into the slot, a rocker arm connected to the outer end of the rotating column, and an insertion slot opened on the push rod and inserted into the other end of the movable rod.

[0010] As a preferred technical solution of this utility model, the slot is opened in a circumferential manner from left to right on the outer wall of the rotating column, and the length of the slot is set to be equal to the length of the space inside the feeding chamber.

[0011] In a preferred embodiment of this invention, the outer end of the push rod is slidably connected to the auxiliary frame, and the movable rod drives the push rod to slide.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0013] 1. Reduce manual operation and improve efficiency: Traditional rotary kiln feeding usually relies on manual tilting and feeding, which not only requires a lot of manual operation, but also increases the labor intensity, especially in high temperature, complex or harsh environments. This device completely eliminates the need for manual operation by controlling the reciprocating motion of the pushing mechanism through the drive mechanism, reducing labor intensity and making the entire feeding process more automated, thus improving work efficiency.

[0014] 2. Precise control of feeding rate: Due to the influence of environmental factors and personnel skill levels, manual operation often makes it difficult to guarantee the accuracy of the feeding rate, resulting in unstable material supply. The design of this device uses a drive mechanism to precisely control the movement of the pushing mechanism, so that the material supply rate can remain consistent. In particular, through the coordinated action of the movable rod and the push rod, the stable pushing and accurate supply of materials can be ensured, thereby avoiding the unstable factors in manual operation and ensuring the consistency and stability of the feeding rate.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example:

[0022] like Figures 1-4 As shown, a feeding device for improving the combustion stability of a rotary kiln includes a rotary kiln body 1. Three sets of support legs 2 are evenly arranged at the bottom end of the rotary kiln body 1. A feeding chamber 3 is provided on the side wall of the rotary kiln body 1. A pushing mechanism 4 is slidably connected in the feeding chamber 3. A driving mechanism 5 is installed on the side wall of the feeding chamber 3. The driving mechanism 5 is connected to the pushing mechanism 4. The driving mechanism 5 drives the pushing mechanism 4 to reciprocate. The pushing mechanism 4 pushes the material in the feeding chamber 3 into the rotary kiln body 1 for combustion.

[0023] The feeding mechanism 4 includes slide rails 41 symmetrically arranged on the outer walls of both sides of the feeding chamber 3, rollers 42 rotatably connected in the slide rails 41, connecting rods 43 rotatably connected to the rollers 42 at one end, push plate 44 connected to the other end of the connecting rod 43, and push rods 45 connected to the outer wall of the push plate 44.

[0024] The operator can drive the push rod 45 to move back and forth through the drive mechanism 5. The push rod 45 drives the push plate 44 to move synchronously. The push plate 44 slides synchronously in the slide rail 41 through the roller 42. The push plate 44 pushes the material in the feeding chamber 3 to the rotary kiln body 1. An opening is provided between the feeding chamber 3 and the rotary kiln body 1 to facilitate the entry of material.

[0025] It is worth noting that the pusher plate 44 is rectangular, which allows it to better contact the material during the pushing process and improve the pushing efficiency. The outer wall of the pusher plate 44 is glued with rubber pads, which can more effectively push the material into the rotary kiln body from all directions.

[0026] The push plate 44 and the push rod 45 are detachably connected by bolts, which facilitates the maintenance and replacement of the equipment. The outer end of the push rod 45 extends to the outside of the feeding chamber 3 and is connected to the drive mechanism 5.

[0027] The drive mechanism 5 includes an auxiliary frame 51 mounted on the outer wall of the feeding chamber 3, a rotating column 52 rotatably connected to the inner wall of the auxiliary frame 51, a slot 53 opened on the outer wall of the rotating column 52, a movable rod 54 with one end inserted into the slot 53, a rocker arm 55 connected to the outer end of the rotating column 52, and an insertion slot 56 opened on the push rod 45 and inserted into the other end of the movable rod 54.

[0028] The operator can manually turn the rocker arm 55, which will cause the rocker arm 55 to drive the rotating column 52 to rotate. The rotation of the rotating column 52 will cause the movable rod 54 connected to it in the slot 53 to move. The movable rod 54 will drive the push rod 45 connected to it to slide. The rotating column 52 will rotate once, causing the movable rod 54 to move back and forth once. Continuing to turn the rocker arm 55 will drive the push rod 45 to move back and forth in a continuous cycle, which will further cause the push plate 44 to push the material in the feeding chamber 3 into the rotary kiln body 1.

[0029] It is worth noting that the slot 53 is opened in a circular pattern on the outer wall of the rotating column 52 from left to right, allowing the movable rod 54 to slide freely in the slot 53 and ensuring that the movable rod 54 can move within the entire length of the feeding chamber 3. The length of the slot 53 is set equal to the length of the space inside the feeding chamber 3, ensuring that the movement of the movable rod 54 can cover the entire area of ​​the feeding chamber 3.

[0030] The outer end of the push rod 45 is slidably connected to the auxiliary frame 51. The movable rod 54 drives the push rod 45 to slide, which in turn drives the push rod 45 to slide back and forth, thereby pushing the push plate 44 to push the material.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
