Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed technology for decomposition furnaces, specifically a device for conveying powdered alternative fuels into a decomposition furnace. Background Technology
[0002] Foam is one of many alternative fuels, characterized by its small particle size, light weight, and high calorific value, and is used as an alternative fuel in cement production. Currently, in cement kiln co-processing, different types of alternative fuels enter the decomposition furnace at different locations and have different combustion times. If different types of alternative fuels use the same inlet channel, the combustion effect of the alternative fuels cannot be fully utilized.
[0003] Based on previous foam experiments, the original alternative fuel channel cannot fully utilize the function and value of foam. In order to further improve the combustion efficiency of foam in the decomposition furnace, a device for conveying powdered alternative fuel into the decomposition furnace is proposed to solve the above problems.

[0025] 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.
[0026] In the embodiments, by Figs. 1-3 The present invention discloses a device for conveying powdered alternative fuel into a decomposition furnace. The device includes a storage bin 1, a weighing scale 2 for weighing the alternative fuel is installed on the inner bottom wall of the storage bin 1, a feeding bin 3 is connected to the top of the storage bin 1, a three-way valve 4 is connected to the outside of the feeding bin 3 and the storage bin 1 through a pipe, a blower 5 is connected to the other end of the three-way valve 4, a linkage switching component 6 is provided between the storage bin 1 and the feeding bin 3, a baffle filter plate 7 is installed inside the feeding bin 3 at the connection point with the three-way valve 4, a feeding pipe 8 is connected to the outside of the feeding bin 3, and a discharge pipe 9 is connected to the outside of the storage bin 1.
[0027] Furthermore, a level gauge is installed inside the storage bin 1, and a controller is installed outside the storage bin 1. The input end of the controller is connected to the level gauge and the weighing scale 2, and the output end of the controller is connected to the linkage switching component 6, the three-way valve 4 and the blower 5.
[0028] In particular, the controller should be equipped with a communication interface, which can be used to link the status of other devices. The current working status can be easily determined by the status of other devices in order to control the feeding and dispensing efficiency.
[0029] Furthermore, the filter plate 7 is inserted into the feed hopper 3, and the feed hopper 3 is provided with a limiting elastic element to limit the movement of the filter plate 7.
[0030] The elastic limiting element is an elastic sheet extending into the interior of the blocking filter plate 7. The elastic sheet can fix the relative position of the blocking filter plate 7, preventing it from shifting due to the vibration of the equipment and thus failing to block the material.
[0031] Furthermore, the linkage switching component 6 includes a spacer 61 fixed between the storage bin 1 and the feed bin 3. A guide block 62 is provided on the top of the spacer 61. A cylinder 63 extending into the storage bin 1 is connected to the outside of the storage bin 1. A blocking frame 64 distributed offset from the spacer 61 is connected to the output end of the cylinder 63.
[0032] Furthermore, both the interior of the spacer 61 and the interior of the sealing frame 64 are provided with multiple interleaved feed holes arranged in an array. The extension and retraction states of the cylinder 63 correspond to the overlapping and interleaved states of the interleaved feed holes, respectively.
[0033] When the blower 5 is not feeding material, the material passage hole can be controlled by the cylinder 63 to become overlapping. At this time, the foam in the feed hopper 3 can be guided by the guide block 62 to directly pass through the material passage hole and reach the storage hopper 1 below to enter the feeding state.
[0034] Furthermore, the connection between the discharge pipe 9 and the storage bin 1 is funnel-shaped, and the other end of the discharge pipe 9 is connected to the decomposition furnace.
[0035] Working principle:
[0036] When this device is working, the linkage switching component 6 is in the closed state by default. At this time, the storage bin 1 and the feeding bin 3 are not connected to each other, and the three-way valve 4 should be switched to the state where the fan 5 is connected to the feeding bin 3. At this time, the fan 5 works to create a negative pressure inside the feeding bin 3, so that the feeding pipe 8 connected to it can adsorb the foam at the designated position and let it enter the feeding bin 3 along with the feeding pipe 8. After the foam enters the feeding bin 3, it cannot move further due to the obstruction of the filter plate 7 and stays inside the feeding bin 3 to complete the feeding operation.
[0037] After the feeding operation is completed, the linkage switching component 6 is in the connected state. At this time, the foam falls into the storage bin 1 under the action of gravity and enters the feeding state. After the foam is ready, the linkage switching component 6 can be switched to the closed state again, and the three-way valve 4 is switched to connect the blower 5 with the storage bin 1. At this time, the blower 5 is started and positive pressure is formed at the storage bin 1, so that the foam is directly fed into the decomposition furnace through the discharge pipe 9 under the action of the blower 5 to complete the feeding operation.
