Description

Technical Field

[0001] This utility model relates to the field of feeder technology, specifically to an impeller feeder for coking. Background Technology

[0002] An impeller feeder is a common continuous feeding machine widely used in industrial fields. Its working principle is based on the rotation of an impeller, which is driven by an electric motor or hydraulic motor to transport materials from the inlet to the outlet.

[0003] The downward conveying of materials by an impeller feeder is a continuous and uniform process. If the feeding speed at the top of the impeller feeder is high, while the impeller feeder speed is constant, and there is no device at the top of the impeller feeder to control the material's descent speed, material will accumulate at the top of the impeller feeder, causing jamming of the impeller. Therefore, we propose an impeller feeder for coking. Utility Model Content

[0004] To address the shortcomings of existing impeller feeders that lack control over the material descent speed at the top, this invention provides a coking impeller feeder with a screw conveyor at the top. This screw conveyor not only transports coal downwards but also prevents coal from accumulating above the feeder, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coking impeller feeder, comprising a feeder, one end of which is driven to rotate by a drive device, and a conveying cylinder on the top of the feeder, the axes of which are perpendicular to each other; a spiral shaft is coaxially arranged inside the conveying cylinder, both ends of which are rotatably connected to the conveying cylinder, and the bottom of the spiral shaft is connected to the drive device through a transmission mechanism; at least one first channel is provided on the bottom side of the conveying cylinder, the bottom of which extends downward and is connected to the feeder; at least one second channel is provided on the top side of the conveying cylinder, the top of which extends upward and is connected to the feed box.

[0008] Optionally, the bottom of the conveyor cylinder is provided with a discharge port corresponding to the position of the first channel, and the top of the first channel is detachably connected to the discharge port.

[0009] Optionally, the feeder includes an installation cylinder located below the conveying cylinder. Sealing covers are detachably installed at both ends of the installation cylinder, and a drive unit is mounted on one of the sealing covers. An installation shaft is coaxially arranged inside the installation cylinder, with both ends rotatably connected to the sealing covers. One end of the installation shaft is connected to the drive unit. Multiple radially arranged material distribution plates are provided on the surface of the installation shaft inside the installation cylinder, with the edges of the material distribution plates fitting with the installation cylinder with a clearance. A discharge channel is provided at the bottom of the installation cylinder, with a flange at the bottom edge of the discharge channel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a coking impeller feeder, including a feeder. For example... Figure 1 As shown, the feeder includes a mounting cylinder 1, such as Figure 1 As shown, the bottom of the mounting cylinder 1 is provided with a discharge channel 13, and the bottom edge of the discharge channel 13 is provided with a flange;

[0023] Sealing caps 2 are detachably installed at both ends of the mounting cylinder 1. The sealing caps 2 are bolted to the ends of the mounting cylinder 1. A mounting shaft 18 is coaxially arranged inside the mounting cylinder 1. Both ends of the mounting shaft 18 are rotatably connected to the sealing caps 2. Multiple material distribution plates 22 are arranged radially on the surface of the mounting shaft 18 inside the mounting cylinder 1. The edges of the material distribution plates 22 are clearance-fitted with the mounting cylinder 1, and a "V"-shaped storage chamber is formed between two adjacent material distribution plates 22.

[0024] The top of the feeder is equipped with a conveying cylinder 4, meaning the mounting cylinder 1 is located below the conveying cylinder 4. The axes of the conveying cylinder 4 and the mounting cylinder 1 are perpendicular to each other. A spiral shaft 21 is coaxially mounted inside the conveying cylinder 4, and both ends of the spiral shaft 21 are rotatably connected to the conveying cylinder 4. Both ends of the conveying cylinder 4 are detachable, as detailed below. Figure 3 As shown, a second end cover 20 is detachably installed at both the upper and lower ends of the conveying cylinder 4. The two are fastened together by bolts. The two ends of the spiral shaft 21 can be rotated and installed at the center of the second end cover 20. In this way, the spiral shaft 21 can be taken out after the second end cover 20 is opened.

[0025] The bottom side of the conveyor cylinder 4 is provided with at least one first channel 3. Specifically, a discharge port 7 corresponding to the first channel 3 is provided at the bottom of the conveyor cylinder 4. The top of the first channel 3 is detachably connected to the discharge port 7, and the two are connected by a flange. The bottom of the first channel 3 extends downward and is connected to the feeder, such as... Figure 1 and Figure 3 As shown, the top of the mounting cylinder 1 is provided with a mounting port 15 corresponding to the first channel 3. The mounting port 15 is detachably connected to the bottom of the first channel 3, and the two are connected by a flange.

[0026] Next, at least one second channel 14 is provided on the top side of the conveyor cylinder 4. The top of the second channel 14 extends upward and is connected to the feed box 5, as detailed below. Figure 1 As shown, a feed inlet 6 is provided at the top of the conveying cylinder 4, which corresponds to the position of the second channel 14. The bottom of the second channel 14 is detachably connected to the feed inlet 6, and the two are connected by a flange.

[0027] The feed box 5 has a flange on its top edge and a conical bottom. The top of the second channel 14 is detachably mounted on the side of the conical structure, and the top of the second channel 14 is connected to the conical surface via a flange. Figure 1 and Figure 2 As shown, there are two second channels 14 and two first channels 3 arranged symmetrically. In this way, the two symmetrical first channels 3 can stably support the conveying cylinder 4, and the two second channels 14 can stably support the feeding box 5.

[0028] During use, coal enters from the feed box 5 and then flows into the top of the conveying cylinder 4 through the second channel 14 at the bottom of the feed box 5. During use, the spiral shaft 21 inside the conveying cylinder 4 rotates continuously, thus conveying the coal downward at a uniform speed. Finally, the coal flows into the mounting cylinder 1 through the first channel 3 at the bottom of the conveying cylinder 4 and falls between the distribution plates 22. Moreover, during use, the mounting shaft 18 also rotates continuously, and then the distribution plates 22 rotate with the mounting shaft 18 to convey the coal downward.

[0029] Furthermore, one end of the feeder is driven to rotate by the drive device, and the bottom of the screw shaft 21 is connected to the drive device through a transmission mechanism. That is, the drive device can drive the mounting shaft 18 to rotate while also driving the screw shaft 21 to rotate, allowing the screw shaft 21 and the mounting shaft 18 to share a single drive device. During installation, specifically, one end of the mounting shaft 18 is connected to the drive device.

[0030] The specific components of the drive unit will be described in detail below, such as... Figure 1 and Figure 2As shown, the drive device is mounted on one of the sealing covers 2. The drive device includes a gearbox 12 mounted on the sealing cover 2. A second bevel gear 17 is provided inside the gearbox 12. The second bevel gear 17 is coaxially mounted on the end of the mounting shaft 18.

[0031] like Figure 3 As shown, the top of the second bevel gear 17 meshes with the first bevel gear 16. The first bevel gear 16 is mounted on the bottom of the drive shaft 8, which extends out from the top of the gearbox 12 and is rotatably connected to the gearbox 12. A drive motor 10 is also mounted on the side of the gearbox 12. The shaft of the drive motor 10 is rotatably mounted on the gearbox 12 and extends into the gearbox 12. A third bevel gear 19 is mounted on the end of the shaft, meshing with the second bevel gear 17. Therefore, when the drive motor 10 rotates, it drives the third bevel gear 19 to rotate, which in turn drives the second bevel gear 17 to rotate. Thus, the second bevel gear 17, while driving the mounting shaft 18 to rotate, also drives the drive shaft 8 to rotate.

[0032] like Figure 3 As shown, the top of the drive shaft 8 is connected to the bottom of the screw shaft 21 through a transmission mechanism. The transmission mechanism includes transmission wheels 9 respectively set at the bottom of the screw shaft 21 and the top of the drive shaft 8. The two transmission wheels 9 are connected by a conveyor belt. The transmission wheels 9 are synchronous pulleys or belt pulleys, and the conveyor belt is a synchronous belt or belt. Therefore, the rotation of the drive shaft 8 can drive the screw shaft 21 to rotate through the transmission wheels 9, so that the screw shaft 21 can continuously and uniformly transport the coal downwards.

[0033] The spiral shaft 21 can uniformly transport coal downwards. Moreover, the side of the spiral shaft 21 is fitted with the conveying cylinder 4 with a clearance, so the coal can only enter the conveying cylinder 4 from the feed box 5 and be transported downwards by the spiral shaft 21. When the spiral shaft 21 stops, the coal will not fall directly into the installation cylinder 1. Therefore, the spiral shaft 21 can effectively prevent the coal from falling directly into the installation cylinder 1 and impacting the distribution plate 22, thus avoiding a large amount of coal accumulating above the distribution plate 22 and causing the distribution plate 22 to get stuck.

[0034] Furthermore, a first end cover 11 is detachably installed at the end of the gearbox 12. The edge of the first end cover 11 is bolted to the end of the gearbox 12. The gearbox 12 contains lubricating oil, which can lubricate the gears.

[0035] It should be noted that in actual application, the size of the third bevel gear 19 should be smaller than that of the second bevel gear 17. This can increase the output torque of the drive motor 10. The size of the first bevel gear 16 can be smaller than that of the second bevel gear 17. This can increase the rotational torque of the screw shaft 21. Of course, the size of the second bevel gear 17 can also be smaller than that of the screw shaft 21. In this case, the screw shaft 21 rotates faster. The speed at which the output coal of the screw shaft 21 matches the storage capacity of the cavity between the material distribution plates 22.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
