Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to an oxygen supply mechanism for an incinerator. Background Art

[0002] An incinerator is a device used to process garbage. It can convert garbage into ashes or other residues through high-temperature combustion, and at the same time generate heat or steam, which can be used for power generation or other industrial purposes. Incinerators are mainly divided into industrial waste incinerators and domestic waste incinerators. The former is mainly used to process industrial waste, while the latter is used to process urban domestic waste. In an incinerator, the main function of oxygen is to support the combustion process of garbage. Garbage needs to undergo a chemical reaction with oxygen to release energy and be converted into ash residue.

[0003] After retrieval, the patent document with the publication number: CN219624052U discloses an oxygen supply mechanism for an incinerator. By turning the handle back, the limit frame is driven to move. When the limit frame disengages from the storage box, the fixing block is driven to move by the elastic force of the first spring. The fixing block drives the support plate to move, and the support plate drives the storage box to move, achieving the effect of facilitating the removal of the storage box. By setting the support device, the effect of facilitating the removal of the storage box is achieved, and it is convenient for workers to maintain the storage box when the oxygen supply equipment is relatively high.

[0004] When the above-mentioned oxygen supply mechanism is actually used, by facilitating the removal of the storage box, it is convenient to organize the activated carbon inside. During this process, when the storage box is opened, air easily flows out along the gap, and an effective air intake process cannot be formed. Moreover, a simple air intake process cannot meet the rapid combustion of garbage. Summary of the Utility Model

Specific implementation mode

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown by Figures 1-3 involving an oxygen supply mechanism for an incinerator, including an oxygen supply box 1, an installation frame 2 is fixedly connected inside the oxygen supply box 1, a suction fan 3 is fixedly connected inside the installation frame 2, and when the suction fan 3 operates, external air enters the oxygen supply box 1 through one of the ventilation pipes 5. Two ventilation pipes 5 are fixedly connected to the outer wall of the installation frame 2, and two docking holes 4 are opened on the outer wall of the installation frame 2. One end of each of the two ventilation pipes 5 communicates with the oxygen supply box 1 through the two docking holes 4 respectively.

[0024] Docking sleeves 6 are threadedly sleeved on the outer walls of both ventilation pipes 5, filter screens 7 are placed inside both docking sleeves 6, annular gaskets 8 are fixedly connected inside both docking sleeves 6, and the filter screen 7 is located between the annular gasket 8 and the ventilation pipe 5. By rotating the docking sleeve 6 to disengage it from the ventilation pipe 5, the filter screen 7 is no longer fixed by the extrusion force and can be taken out of the docking sleeve 6, facilitating its replacement.

[0025] The inner walls of both ventilation pipes 5 are rotatably connected with circular rubber sheets 9. The outer wall of the circular rubber sheet 9 is fixedly connected with a rotating rod, and a nut is sleeved on the outer wall of the rotating rod to increase the stability between the rotating rod and the ventilation pipe 5. One end of the rotating rod penetrates through the outer wall of the ventilation pipe 5, and the rotating rod drives the circular rubber sheet 9 to rotate. There is an interference fit between the circular rubber sheet 9 and the ventilation pipe 5. When the circular rubber sheet 9 is vertically arranged, the ventilation pipe 5 is blocked. When the circular rubber sheet 9 is horizontally arranged, the ventilation pipe 5 is opened. Therefore, when the two ventilation pipes 5 are opened and closed relative to each other, it is realized by rotating the circular rubber sheet 9. An air outlet hole 10 is opened on the outer wall of the oxygen supply tank 1.

[0026] A negative pressure mechanism is provided on the outer wall of the oxygen supply tank 1. The negative pressure mechanism includes a first conical pipe 11. One end of the first conical pipe 11 is fixedly communicated with the outer wall of the oxygen supply tank 1. The other end of the first conical pipe 11 is fixedly communicated with a thin pipe 12. A suction pipe 14 is fixedly communicated with the outer wall of the thin pipe 12. One end of the suction pipe 14 is fixedly communicated with an accelerant barrel. One end of the thin pipe 12 is fixedly communicated with a second conical pipe 13. A flange 15 is fixedly sleeved on the outer wall of the second conical pipe 13. A conical sleeve 16 is fixedly connected inside the thin pipe 12. When the air flow flows from the thick pipe into the thin pipe 12, due to the reduction of the pipe cross-sectional area, the flow rate will increase. According to Bernoulli's principle, the increase in the flow rate will cause the pressure at this position to decrease, thus generating a negative pressure phenomenon.

[0027] Working principle: During use, the flange 15 on the second conical pipe 13 is docked with the intake port of the incinerator. The suction fan 3 operates to draw in outside air through the ventilation pipe 5 with a horizontal circular rubber sheet 9. The air flow is filtered through the filter net 7. The filtered air enters the oxygen supply tank 1 through one of the docking holes 4 and then enters the first conical pipe 11 along the air outlet hole 10. The air flow enters the conical sleeve 16 and the second conical pipe 13 from the thin pipe 12. During this process, the air flow enters the thin pipe 12 from the thick first conical pipe 11. According to Bernoulli's principle, the air flow rate increases and the pressure decreases, generating a negative pressure phenomenon near the conical sleeve 16. Under the action of the negative pressure, the liquid accelerant in the accelerant barrel enters the thin pipe 12 through the suction pipe 14 and then enters the second conical pipe 13 along with the air flow. The accelerant enters the incinerator through the air flow, further improving the combustion assistance effect; when replacing the filter net 7, rotate the two rotating rods to drive the two circular rubber sheets 9 to rotate, so that the upper and lower ventilation pipes 5 are opened and closed relatively, forming an up-and-down switching process, which is convenient for replacing the filter net 7 and does not affect the air intake process. At the same time, rotate the docking sleeve 6 to remove the filter net 7 for replacement.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described in this specification in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model.
