Technical Field

[0001] The utility model relates to the technical field of fertilizer production carbonization equipment, in particular to a carbonization device for fertilizer production. Background Art

[0002] In recent years, the fertilizer utilization of biomass such as crop straw has attracted the attention of all parties. Among them, the application of biomass carbon formed by carbonizing crop straw in the production of compound fertilizers has significant effects on soil improvement and crop yield increase. In addition, the carbonization of crop straw to form biomass carbon also helps to reduce the emission of greenhouse gases such as carbon dioxide, which has a good promoting effect on the development of low-carbon agriculture and soil carbon sequestration;

[0003] During the use of the existing carbonization furnace, in order to ensure the full combustion of the materials inside the furnace body, oxygen supply work generally needs to be carried out. The traditional oxygen supply work generally uses an air pump to directly supply oxygen into the carbonization furnace. However, in actual operation, we found that since the gas temperature of the outside air is relatively lower than the temperature inside the furnace body, its direct injection will consume more heat inside the furnace body through heat exchange, resulting in a large amount of unnecessary heat energy loss. Therefore, how to solve this problem needs to be considered. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a carbonization device for fertilizer production is proposed. During the use of this device, the heat energy in the gas discharged from the inside of the furnace body can be reused, reducing unnecessary heat energy loss. In addition, the combination of the filter screen at the air outlet part and the cover body facilitates the subsequent cleaning work of the filter screen.

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

[0007] Preferably, a rectangular groove is formed in the front side of the collection box, and a collection box is placed in the rectangular groove.

[0008] Preferably, a placement net is installed inside the carbonization furnace body.

[0009] Preferably, one side of the cover body is hinged to the feed inlet, and the other side of the cover body is connected to the upper end of the feed inlet through a buckle.

[0010] Preferably, the oxygen supply mechanism includes a blower installed at the upper end of the mounting plate. The air outlet end of the blower is communicated with a spiral temperature guiding pipe, and the air outlet end of the spiral temperature guiding pipe extends to the bottom inside the carbonization furnace body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Referring to Figures 1-3 , a carbonization device for fertilizer production, including a carbonization furnace body 1. The carbonization furnace body 1 is also provided with an electric combustion structure (not shown) for realizing the combustion work, which is the prior art. An installation frame 2 is installed at the lower end of the carbonization furnace body 1, a feed inlet 7 is installed at the upper end of the carbonization furnace body 1, a sealing door 16 is installed on the front side of the carbonization furnace body 1, a connecting pipe 4 is connected to the lower end of the carbonization furnace body 1, and a placement net 15 is installed inside the carbonization furnace body 1;

[0020] Among them, a collection mechanism is further included. The collection mechanism includes a collection box 3 arranged below the carbonization furnace body 1. The lower end of the connecting pipe 4 extends into the interior of the collection box 3 and is fixedly connected to the collection box 3. A rectangular groove 6 is opened on the front side of the collection box 3, and a collection box 5 is placed in the rectangular groove 6;

[0021] Among them, a sealing and filtering mechanism is further included. The sealing and filtering mechanism includes a cover body 8 installed at the upper end of the feed inlet 7. One side of the cover body 8 is hinged to the feed inlet 7, and the other side of the cover body 8 is connected to the upper end of the feed inlet 7 through a buckle. A filter screen 14 is installed inside the cover body 8. The inner top space of the cover body 8 is communicated with a hose 9. The hose 9 is made of a high-temperature resistant material. The other end of the hose 9 is fixedly connected to a temperature conduction connecting pipe 10. The other end of the temperature conduction connecting pipe 10 is connected to an external gas purification structure for purifying the discharged polluting gas. The upper end of the carbonization furnace body 1 is fixedly connected to a mounting plate 12. The temperature conduction connecting pipe 10 passes through the mounting plate 12 and is fixedly connected to the mounting plate 12;

[0022] Among them, an oxygen supply mechanism is further included. The oxygen supply mechanism is used to supply oxygen to the carbonization furnace body 1. The oxygen supply mechanism includes a blower 13 installed at the upper end of the mounting plate 12. The air outlet end of the blower 13 is communicated with a spiral temperature conduction pipe 11. The air outlet end of the spiral temperature conduction pipe 11 extends to the inner bottom of the carbonization furnace body 1. The spiral temperature conduction pipe 11 is wound around the temperature conduction connecting pipe 10 and is in contact with the temperature conduction connecting pipe 10.

[0023] In the present utility model, in actual use, first open the cover body 8, then put the raw materials to be carbonized from the feed inlet 7, then close the cover body 8, and start the electric combustion structure inside the carbonization furnace body 1 to burn. During the burning process, the blower 13 can be started simultaneously. The blower 13 will inject the outside air into the carbonization furnace body 1 through the spiral temperature conduction pipe 11 for oxygen supply;

[0024] During the raw material combustion and carbonization process in the carbonization furnace body 1, the flue gas generated will be discharged through the cover body 8, and enter the external purification structure through the hose 9 and the temperature-conducting connecting pipe 10. Since the discharged flue gas is high-temperature flue gas, when the high-temperature flue gas passes through the temperature-conducting connecting pipe 10, it will use heat exchange to heat the gas in the spiral temperature-conducting pipe 11, that is, the gas entering the carbonization furnace body 1 is preheated gas, which can reduce the heat consumed by the external air entering the carbonization furnace body 1 and reduce the unnecessary waste of heat energy in the carbonization furnace body 1;

[0025] The carbonized ash will pass through the placement net 15 and finally fall into the collection box 5, which is convenient for subsequent collection. Before the flue gas enters the hose 9, it will also be filtered by the filter screen 14 to prevent the situation where some ash bodies move upward with the hot air and block the subsequent smoke exhaust pipe. The staff only needs to open the cover body 8 to clean the filter screen 14.

[0026] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
