[0039] like Figures 1-3 As shown, the present application discloses a sequential powder material propulsion mechanism inside a rotary kiln, which is used to complete the propulsion of materials. Specifically, the corresponding structure is used to realize sequential propulsion of the feed, and at the same time, the short flow of materials in the rotary kiln can be strictly controlled.

[0040] like Figure 1 As shown, the specific structure of this application includes:

[0041] Cylinder 1, which is an existing device, is loaded with materials for corresponding processing;

[0042] Multiple baffle assemblies 2 are installed at intervals inside the cylinder 1, and the baffle assemblies 2 are distributed along the length direction of the cylinder 1. The baffle assemblies 2 are installed inside the cylinder 1 to divide the interior of the cylinder 1 into multiple cavities in sequence, which is convenient for process treatment at different temperatures, thereby ensuring product quality;

[0043] The partition assembly 2 includes:

[0044] A partition 201, the outer edge of which is connected to the inner wall of the cylinder 1, and a material passage hole 202 is opened in the middle of the partition 201;

[0045] At least one discharge spoon 203 is installed on the side of the partition 201, and the end of the discharge spoon 203 cooperates with the through hole 202; the partition assembly 2 in this application is divided into multiple parts. First, the partition 201 divides the internal space of the entire cylinder 1, and at the same time, the discharge spoon 203 can scoop up the material in the divided cavity and then continue to push it backward.

[0046] In order to ensure the stability of the partition plate during assembly, the partition plate 201 in the application is a circular plate, which can better adapt to the inner wall of the cylinder 1. Meanwhile, since the working condition of the cylinder 1 is in a hot state, in order to avoid the expansion of the partition plate 201 due to heat, affecting the stability of the overall structure, a plurality of expansion joints 204 are arranged in the circumferential direction of the partition plate 201, thereby providing an expansion allowance.

[0047] In order to ensure work efficiency, the discharge spoon 203 is two, which can improve work efficiency; the discharge spoon 203 is arranged at intervals, and the discharge spoon 203 is located on both sides of the material hole, which can realize stable discharge, and the two discharge spoons 203 will not affect each other.

[0048] In an embodiment, in order to further ensure work efficiency, the two discharge spoons 203 in the application are rotationally symmetric about the center of the material hole 202, so that once every 180 degrees, the material can be taken, thereby ensuring efficiency.

[0049] In order to ensure that the material can enter the next cavity from the material hole 202, a groove 205 is arranged in the discharge spoon 203, so that the material can be stored in the groove 205, and after rotation, gradually flow into the material hole 202, thereby entering the next cavity.

[0050] The discharge spoon 203 in the application can be of various shapes or structures, as long as the material can flow from the material hole 202 into the next cavity, preferably, as shown in Figure 2 、 3 The discharge spoon 203 in the application comprises:

[0051] The material holding groove 206 is arranged on the side of the partition plate 201;

[0052] The material inlet groove 207 is in communication with the material holding groove 206 at one end and in communication with the material hole 202 at the other end; the discharge spoon 203 in the application is an integral molded part, which uses the material holding groove 206 to scoop the material, and the subsequent material flows into the next cavity from the material inlet groove 207.

[0053] Specifically, the groove bottom of the material holding groove 206 is arc-shaped, so that the material can flow better after scooping.

[0054] In order to ensure the flow effect of the material after scooping, the material inlet groove 207 extends obliquely from the connection with the material holding groove 206 to the center of the material hole 202, so that the material can flow to the material hole 202 easily.

[0055] In order to further ensure the flow effect of the material, the feeding slot 207 is provided with a feeding port 208 away from one end of the material holding groove 206, and the feeding port 208 and the material holding groove 206 are respectively located on both sides of the partition plate 201, so that the material can better enter the next cavity.

[0056] The material holding groove 206 is located at the outer edge of the partition plate 201 away from one end of the feeding slot 207, so that the material can be better scooped.

[0057] Further description is made for the present application:

[0058] The present application is mainly applied to petroleum coke ultrafine powder, and the following advantages can be achieved by using the present application in the rotary kiln granulation process: the material height in the rotary kiln can be balanced; the material advancing speed can be automatically adjusted according to the material height; all materials realize sequential advancement in the kiln to prevent short flow.

[0059] Specifically, the present application is provided with a partition plate assembly 2, which divides the cylinder 1 into a plurality of independent bins, and the material is sequentially pushed along the first independent bin to the second independent bin, and the material is pushed by the material scoop installed on the partition plate.

[0060] The material scoop in the present application includes a material holding groove and a feeding slot, and the cross section is similar to a half-moon shape, and the width is determined according to the material discharge amount. The material scoop is rotated by the rotary kiln, and when the scoop tip is in the 180° direction, the bottom powder is scooped into the scoop, and when it is rotated to 270°, the powder slides into the second independent bin by gravity. The half-moon design can automatically scoop the material according to the material height of the front independent bin. When the material height is low, the scooped material amount is less, and vice versa. When the highest material layer is reached, the material scoop can meet the demand of production capacity. By designing the width, height and rotation speed of the kiln, the maximum scooped amount of the material scoop can be adjusted; the scooped amount of the material scoop is automatically adjusted by the height of the front bin.
