Description

Technical Field

[0001] This utility model relates to a gravity sealing valve for the material outlet of a carbonization rotary kiln, belonging to the technical field of rotary kilns, specifically to a material outlet valve for rotary kilns. Background Technology

[0002] A carbonization rotary kiln is a production kiln structure that requires a transmission device to continuously rotate the kiln body and isolates its interior from the external environment. During this process, hot air needs to be continuously supplied to the kiln to calcify the material inside the tubes. To improve production efficiency, modern rotary kilns are evolving towards continuous production, which necessitates addressing the sealing issues during material feeding and discharging. Previously, the material outlet used a rotary sealing structure. However, due to the rotation, this structure resulted in the activated carbon being easily broken during discharge, affecting production quality. Utility Model Content

[0003] To address one of the aforementioned technical deficiencies, this utility model provides a gravity sealing valve for the material outlet of a carbonization rotary kiln, enabling continuous material discharge and ensuring discharge quality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a gravity sealing valve for the material outlet of a carbonization rotary kiln, including at least one gravity sealing valve unit. The gravity sealing valve unit includes a feed pipe, a valve chamber, a rotating shaft, a sealing plate, and a counterweight. The upper end of the feed pipe is provided with a first connecting flange and is connected to the discharge port of the rotary kiln through the first connecting flange. The upper part of the valve chamber is fixedly connected to the feed pipe, and the outlet of the feed pipe is located inside the valve chamber. The sealing plate covers the outlet of the feed pipe. A rotating shaft is fixedly installed at one end of the sealing plate. The rotating shaft is rotatably installed on the valve chamber, and its two ends extend outside the valve chamber. Counterweights are fixedly installed at both ends of the rotating shaft located outside the valve chamber. A material discharge port is provided at the bottom end of the valve chamber.

[0005] The material discharge port is provided with a second connecting flange, and multiple gravity sealing valve units are connected in series to form a multi-layer gravity sealing valve structure. The first connecting flange of the next gravity sealing valve unit is connected to the second connecting flange of the previous gravity sealing valve unit to achieve series connection.

[0006] The outlet of the feed pipe is a sloping outlet, and its higher end is close to the rotating shaft.

[0007] The counterweight component includes a screw, counterweight plates, and nuts. One end of the screw is fixed to the end of the rotating shaft. The screw has a threaded section, and multiple counterweight plates are fitted onto the threaded section. The two sides of the counterweight plates are fastened and fixed by nuts screwed onto the screw.

[0008] The gravity sealing valve at the material outlet of the carbonization rotary kiln provided by this utility model can effectively reduce the breakage rate of the finished material while ensuring sealing performance.

[0009] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by way of what is pointed out in the written description, claims, and drawings. Attached Figure Description

[0010] The accompanying drawings, which are included to provide a further understanding of the present invention and constitute a part of this invention, illustrate exemplary embodiments of the present invention and, together with the description thereof, serve to explain the present invention and do not constitute an undue limitation thereof. In the drawings:

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] like Figure 1 As shown, the present invention relates to a gravity sealing valve for the material outlet of a carbonization rotary kiln, comprising at least one gravity sealing valve unit. The gravity sealing valve unit includes a feed pipe 1, a valve chamber 2, a rotating shaft 3, a sealing plate 4, and a counterweight 5. The upper end of the feed pipe 1 is provided with a first connecting flange 7 and is connected to the discharge port of the rotary kiln through the first connecting flange 7. The upper part of the valve chamber 1 is fixedly connected to the feed pipe 1, and the outlet of the feed pipe 1 is located inside the valve chamber 2. The sealing plate 4 covers the outlet of the feed pipe 1. A rotating shaft 3 is fixedly installed at one end of the sealing plate 4. The rotating shaft 3 is rotatably installed on the valve chamber 2, and its two ends extend outside the valve chamber 2. A counterweight 5 is fixedly installed at both ends of the rotating shaft 3 located outside the valve chamber 2. A discharge port 6 is provided at the bottom end of the valve chamber 2.

[0015] This utility model, in the non-discharge state, such as Figure 1The diagram shows the state where the sealing plate 4 blocks the outlet of the feed pipe 1. During discharge, the material's own weight overcomes the force exerted on the sealing plate 4 by the counterweight 5, causing the sealing plate 4 to descend and open the pipe outlet to facilitate material discharge. When no material is being discharged, the sealing plate 4 returns to the blocking state under the action of the counterweight 5. This ensures both sealing performance and the continuity and flow rate of the discharge. Compared to the existing rotary sealing discharge structure, it can also effectively reduce the breakage rate of the finished material.

[0016] A second connecting flange 8 is provided on the material discharge port 6, such as Figure 2 As shown, multiple gravity sealing valve units are connected in series to form a multi-layer gravity sealing valve structure. The first connecting flange 7 of the next gravity sealing valve unit is connected to the second connecting flange 8 of the previous gravity sealing valve unit to achieve series connection. The multi-layer gravity sealing valve allows other sealing plates to be relatively closed when one sealing plate 4 is open, which can more effectively ensure the sealing of the discharge and reduce the first drop height of the material, further reducing the breakage of the finished material.

[0017] The outlet of the feed pipe 1 is a sloping outlet and its higher end is close to the rotating shaft 3.

[0018] The counterweight 5 includes a screw, a counterweight plate, and a nut. One end of the screw is fixed to the end of the rotating shaft 3. The screw has a threaded section, and multiple counterweight plates are fitted on the threaded section. The two sides of the counterweight plates are fastened by nuts screwed onto the screw. The number of counterweight plates can be selected to adjust the size of the counterweight, thereby adjusting the amount of material discharged at one time.
