[0002] A reformer is a chemical equipment that converts hydrocarbons into syngas in the presence of a catalyst. When the materials in the reformer have reacted completely or new reaction materials need to be added, the feed inlet of the reformer needs to be opened. It is the core equipment in a hydrogen production unit and plays an important role in various chemical productions.

[0003] In the prior art, most of the feed inlets of reformers are provided with a feed cover. When the feed cover is opened and the feed inlet is continuously feeding, the feed inlet of the reformer is directly communicated with the outside air, and a large amount of heat in the inner cavity of the reformer will be lost, which may lead to the following consequences: one is to reduce the temperature in the furnace, affecting the activity and reaction rate of the catalyst, and further affecting the production efficiency; the other is to increase energy consumption. In order to maintain the temperature in the furnace, more energy needs to be consumed. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem that most of the feed inlets of reformers in the prior art are provided with a feed cover. When the feed cover is opened and the feed inlet is continuously feeding, the feed inlet of the reformer is directly communicated with the outside air, and a large amount of heat in the inner cavity of the reformer will be lost, which may lead to the following consequences: one is to reduce the temperature in the furnace, affecting the activity and reaction rate of the catalyst, and further affecting the production efficiency; the other is to increase energy consumption. In order to maintain the temperature in the furnace, more energy needs to be consumed, and a reformer with uniform heat reception is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A reformer with uniform heat reception, including a lower furnace body, the top of the lower furnace body is fixedly provided with an upper furnace body by bolts, the top edge position of the upper furnace body is vertically fixedly communicated with a vertical cylinder, the top of the side surface of the vertical cylinder is fixedly connected with a feed hopper, the middle position of the top of the upper furnace body is fixedly provided with a stirring motor, the output end of the stirring motor is fixedly provided with a vertical column, and heating rods are equidistantly arranged on the outer wall of the vertical column. A buffer feeding component is arranged inside the vertical cylinder to reduce the heat loss inside the upper furnace body when filling materials into the upper furnace body.

[0007] Optionally, the buffer feeding component includes a support frame, a central column, a closing disk, and a closing frustum. The support frame is vertically and fixedly arranged on the top of the upper furnace body.

[0008] Optionally, the support frame is vertically inserted with a central column in a movable manner. A bottom limit disk is fixedly arranged below the support frame on the central column, and a top limit disk is fixedly arranged above the support frame on the central column.

[0009] Optionally, a closed disk is fixedly arranged on the outer wall of the central column below the bottom limit disk, and a closed frustum is fixedly arranged on the central column below the closed disk.

[0010] Optionally, support legs are circularly arranged at the bottom of the lower furnace body, and a release valve is arranged at the center of the bottom of the lower furnace body.

[0011] Optionally, the diameters of the closed disk and the closed frustum are the same as the inner diameter of the vertical cylinder, and the top of the closed frustum has a structure that is narrower at the top and wider at the bottom.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. The present utility model is provided with a vertical cylinder at the top of the upper furnace body. The vertical cylinder is a so-called "feeding port structure", and a feeding buffer assembly is arranged in the inner cavity of the vertical cylinder. When the vertical cylinder is continuously fed, the feeding buffer assembly enables the vertical cylinder not to communicate with the outside air, which can completely solve the problem in the prior art that most of the feeding ports of reforming furnaces are provided with a material cover. When the material cover is opened and the feeding port is continuously feeding, the feeding port of the reforming furnace is directly communicated with the outside air, and a large amount of heat in the inner cavity of the reforming furnace will be lost, which may lead to the following consequences: First, it reduces the temperature in the furnace, affects the activity and reaction rate of the catalyst, and further affects the production efficiency; Second, it increases energy consumption. In order to maintain the temperature in the furnace, more energy needs to be consumed. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Referring to Figures 1 - 3 , a reforming furnace with uniform heat distribution, including a lower furnace body 22, an upper furnace body 2 is fixedly arranged on the top of the lower furnace body 22 by bolts, a vertical cylinder 5 is vertically fixedly connected to the top edge position of the upper furnace body 2, a feeding hopper 3 is fixedly connected to the top of the side surface of the vertical cylinder 5, an inclined opening is arranged at the bottom of the feeding hopper 3, and workers can introduce materials into the vertical cylinder 5 through the large-volume feeding hopper 3.

[0021] A stirring motor 6 is fixedly arranged at the middle position of the top of the upper furnace body 2, a vertical column 21 is fixedly arranged at the output end of the stirring motor 6, and heating rods 1 are equidistantly arranged on the outer wall of the vertical column 21, so that the materials inside the closed space formed by the upper furnace body 2 and the lower furnace body 22 are heated evenly. A buffer feeding component for reducing the heat loss inside the upper furnace body 2 when filling materials into the upper furnace body 2 is arranged inside the vertical cylinder 5.

[0022] The buffer feeding component includes a support frame 4, a central column 10, a closed disk 9, and a closed frustum 11. The support frame 4 is vertically and fixedly arranged on the top of the upper furnace body 2, the central column 10 is movably inserted into the support frame 4 along the vertical direction, a bottom limit disk 8 is fixedly arranged below the support frame 4 on the central column 10, a top limit disk 7 is fixedly arranged above the support frame 4 on the central column 10, a closed disk 9 is fixedly arranged on the outer wall of the central column 10 below the bottom limit disk 8, and a closed frustum 11 is fixedly arranged on the central column 10 below the closed disk 9.

[0023] Support legs 23 are circularly arrayed at the bottom of the lower furnace body 22, a release valve 220 is arranged at the central position of the bottom of the lower furnace body 22, the diameters of the closed disk 9 and the closed frustum 11 are the same as the inner diameter of the vertical cylinder 5, and the top of the closed frustum 11 has a structure that is narrower at the top and wider at the bottom.

[0024] The specific implementation steps and principles of the present utility model are as follows:

[0025] In the initial state, the top limit disc 7 is placed on top of the support frame 4. At this time, the closed frustum 11 extends into the upper furnace body 2 and the lower furnace body 22. The closed disc 9 closes the top of the vertical cylinder 5. When feeding the upper furnace body 2 and the lower furnace body 22 is required, the central column 10 is lifted manually so that the bottom limit disc 8 abuts against the bottom of the support frame 4. At this time, the closed frustum 11 closes the top of the vertical cylinder 5. Manually add enough materials into the vertical cylinder 5 through the feeding hopper 3. Finally, lower the central column 10. Under the gravity of the materials, all the components on the entire central column 10 move downward. During this process, the closed disc 9 will first close the vertical cylinder 5, and the closed disc 9 continues to move downward until the top limit disc 7 is placed on top of the support frame 4 again. At this time, the closed frustum 11 extends into the upper furnace body 2 and the lower furnace body 22. Since the closed frustum 11 has a structure that is narrower at the top and wider at the bottom, the materials at the top of the closed frustum 11 fall into the upper furnace body 2 and the lower furnace body 22.
