Description

Technical Field

[0001] This invention belongs to the technical field of lime production equipment, specifically relating to a rotary feeder for lime kilns. Background Technology

[0002] In the lime production process, proper material distribution in the lime kiln is a crucial part of lime production. Proper and uniform material distribution is conducive to the full calcination of the material. Traditional material distributors generally use four-point distribution, which can result in uneven distribution, uneven burning, damage to the refractory bricks inside the kiln, and a reduction in the service life of the lime kiln. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a simple rotating material distributor for lime kilns. This distributor can achieve uniform material distribution to the lime kiln through its upper and lower layers of material distribution holes, thereby avoiding uneven material distribution and resulting in uneven burning.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotary feeder for a lime kiln includes an upper hopper and a lower rotating shell. The rotating shell rotates relative to the hopper, and the hopper outlet is connected to the rotating shell inlet.

[0006] The hopper is equipped with a motor, and the feed inlet of the rotating outer shell is equipped with a gear ring. The power output end of the motor is a gear that meshes with the gear ring.

[0007] The rotating shell includes a first layer of fabric tubes and a second layer of fabric tubes. The first layer of fabric tubes is located above the second layer of fabric tubes, and fabric holes are distributed on the first layer of fabric tubes and the second layer of fabric tubes.

[0008] The rotating housing has an internal baffle for adjusting the material flow to the first or second layer of the material distribution pipe. The internal baffle moves up and down inside the rotating housing.

[0009] As a further preferred embodiment, the inner wall of the feed inlet of the rotating shell is provided with a chute for the internal baffle to move up and down. The internal baffle includes an upper chute fitting and a lower base plate. The chute fitting and the lower base plate are fixedly connected by a connecting rod. The area between the chute fitting and the base plate is a material channel. The chute fitting is a cylindrical structure with openings at both ends, and the base plate is a circular structure. The outer surface of the chute fitting has a pin embedded in the chute, and the base plate has a long shaft for manual rotation. The long shaft passes through the rotating shell and the hopper, with its end located on the outside.

[0010] As a further preferred embodiment, the chute is arranged obliquely on the inner wall of the feed inlet of the rotating shell. There is a horizontal groove at each end of the chute. When the pin is located at the upper end of the chute, the bottom plate blocks the first layer of material distribution pipe and the second layer of material distribution pipe, and the material channel is connected to the first layer of material distribution pipe. When the pin is located at the lower end of the chute, the chute blocks the first layer of material distribution pipe, and the material channel is connected to the second layer of material distribution pipe.

[0011] As a further preferred embodiment, the rotating housing is provided with at least one set of first-layer fabric distribution pipes and one set of second-layer fabric distribution pipes, with the first-layer fabric distribution pipes or the second-layer fabric distribution pipes arranged in a straight line, and the length of the first-layer fabric distribution pipes being greater than that of the second-layer fabric distribution pipes.

[0012] As a further preferred embodiment, the fabric holes are distributed on the lower surface of the end position of the first layer fabric pipe or a group of second layer fabric pipes; the lower side of the end of the first layer fabric pipe and the group of second layer fabric pipes is provided with openings.

[0013] As a further preferred embodiment, the feed inlet of the rotating shell is provided with an outer ring, which is fixed to the hopper by a support column. A ring plate is provided inside the outer ring, and a groove is provided circumferentially for the feed inlet of the rotating shell, with the ring plate limited to rotating within the groove.

[0014] As a further preferred option, the hopper is equipped with a fixing bar, the upper limit of which is located on the long axis in the circumferential rotation direction.

[0015] Compared with existing technologies, this invention has the following advantages: This invention uses two layers of material distribution pipes to evenly distribute material onto the outer and inner rings respectively, thereby avoiding uneven burning caused by uneven material distribution and preventing damage to the lime kiln. Simultaneously, uniform material distribution also improves product quality. Furthermore, the structure is simple; rotating the internal sliding groove of the outer shell simultaneously drives the internal baffles to move automatically up and down.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] like Figure 1 As shown, a lime kiln rotary feeder consists of a hopper 1, a rotating outer shell 3, a drive gear 4, a motor 2, and an internal baffle. Figure 5 Composition. The hopper is supported by four pillars. The ring plate 16 below the pillars fits into the slot 5 on the outer perimeter of the rotating shell 3. The lower outlet end of the hopper 1 is attached to the upper end of the rotating shell 3. In this way, while the rotating shell 3 is rotating, the rotating shell 3 will not move up and down, but will only rotate within the ring plate 16. This achieves the goal of preventing the rotating shell 3 from moving up and down and only allowing it to rotate.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 7As shown, the rotating outer shell has a circular groove 9 inside, which surrounds the inner wall of the rotating outer shell. The distance between the highest and lowest points of the groove 9 is 0.4 meters. The groove 9 is 40 millimeters wide and 20 millimeters deep. The groove 9 cooperates with the pin 12 on the internal lifting baffle. This allows the internal lifting baffle to move along the track of the groove 9 while the rotating outer shell 3 rotates, thus moving the lifting baffle back and forth with a vertical range of 0.4 meters. Two layers of fabric distribution pipes are designed below the rotating outer shell. The first layer of fabric distribution pipes 6 has a total length of 2.5 meters. Fabric holes 8, each 50 millimeters in size, are opened at the ends of the fabric distribution pipes on both sides. In the initial position, the internal vertically moving baffle blocks the second layer of fabric distribution pipes 7, opening the first layer of fabric distribution pipes 6, allowing for outer ring fabric distribution. During the rotation of the rotating outer shell... The internal baffle moves downwards, blocking the first layer of the material distribution pipe 6 and opening the second layer of the material distribution pipe 7. The second layer of the material distribution pipe is designed to be 1.5 meters long, and it also has a material distribution hole with a diameter of 50 mm at the end of the pipe. At this point, the material can enter the second layer of the material distribution pipe for inner ring distribution. At the same time, the opening 10 at the end of the two layers of material distribution pipes is a circular baffle with its lower part cut off, and the lower part of the baffle has a gap of 70 mm in height, which can also be used for material outflow, facilitating material distribution. In this way, material can be distributed to the outer and inner rings separately. At the same time, the rotating shell can distribute material back and forth between the outer and inner rings during rotation, and the rotation can also make the material flow evenly to both sides of the material distribution pipe, thereby achieving the purpose of uniform material distribution.

[0027] like Figure 5 , Figure 6As shown, the internal lifting baffle consists of two layers plus a long shaft 13. The first layer is a sealed baffle that blocks material from entering the first layer of the distribution pipe 6. A pin 12 is located at the upper edge of the first layer, which engages with a groove 9 on the inner wall of the rotating housing, allowing the internal baffle to move up and down. The second layer consists of four pillars and a base plate 14. This second layer is an open layer that allows material to flow into the second layer of the distribution pipe 7. During the up-and-down movement of the internal lifting baffle, the closed baffle of the first layer blocks the open baffle of one layer of the distribution pipe, opening the other layer of the distribution pipe. This achieves the purpose of switching between the two distribution pipes for material distribution. A long shaft 13 with a regular hexagonal cross-section is fixedly connected to the middle of the base plate 14. The long shaft 13 extends directly to the top of the hopper 1. A fixed plate 15 is set at the upper feed inlet of the hopper. A regular hexagonal opening is opened on the fixed plate, the size of which matches the cross-section of the long shaft. This allows the long shaft 13 to move up and down in the fixed plate 15. However, due to the limitation of the regular hexagon, it cannot rotate. Thus, the internal lifting baffle can only move up and down and cannot rotate with the rotating outer shell. The pin 12 at the upper end of the baffle can cooperate with the slide 9 to realize the up and down reciprocating motion of the internal baffle. When it is necessary to adjust the flow of material into the first layer of the feeding pipe 6 or the second layer of the feeding pipe 7, the long shaft 13 can be rotated. The long shaft 13 rotates synchronously with the hopper 1 through the fixed strip 15.

[0028] The specific operation is as follows: Material is poured into the hopper 1 and then enters the rotating outer shell through the lower outlet 17. Initially, the open layer of the internal lifting baffle aligns with the first layer of the material distribution pipe 6, while the second layer of the material distribution pipe 7 is closed. Material flows out through the first layer of the material distribution pipe 6 and is distributed in the outer ring at the opening at the outer end of the pipe. As the rotating outer shell rotates, the internal sliding groove 9 engages with the pin 12 on the baffle, causing the baffle to move downwards. At this time, the second layer of the material distribution pipe 7 can be opened, thus closing the first layer of the material distribution pipe 6. Material enters the second layer of the material distribution pipe 7 for inner ring distribution. Furthermore, the internal lifting baffle, through the engagement of the pin 12 and the sliding groove 9, reciprocates up and down while the rotating outer shell rotates, thus achieving uniform material distribution by evenly alternating the outer and inner rings.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
