Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, specifically an oxygen supply mechanism for an incinerator. Background Technology

[0002] Incinerators require oxygen supply because oxygen is essential for combustion. It reacts chemically with combustible materials in waste, promoting combustion and decomposition, transforming waste into harmless substances. At high temperatures, a sufficient oxygen supply ensures complete combustion of the incinerated materials, reducing the production of toxic and harmful substances, while releasing a large amount of heat energy for heating, power generation, and other purposes, achieving energy recycling. Therefore, oxygen supply is a crucial element for the efficient and safe operation of incinerators. However, existing incinerator oxygen supply mechanisms suffer from uneven oxygen distribution, leading to incomplete combustion in certain areas and the production of large amounts of combustible gases such as carbon monoxide. These gases accumulate in the furnace, increasing the risk of explosion if they encounter sufficient oxygen and an ignition source. Furthermore, the high-temperature and high-pressure environment inside the oxygen supply mechanism further increases the risk of explosion. Therefore, this paper proposes an improved oxygen supply mechanism for incinerators. Utility Model Content

[0003] The purpose of this invention is to provide an oxygen supply mechanism for an incinerator to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An oxygen supply mechanism for an incinerator includes,

[0006] An annular pipe, wherein an output head for preventing backfire is provided on the inner side of the annular pipe;

[0007] A pressure relief assembly is disposed on the outside of the annular pipe for pressure relief.

[0008] Preferably, the output head includes:

[0009] The head body has a vent plate fixedly connected inside it, and the vent plate has multiple vent holes.

[0010] The cylindrical body is fixedly connected inside the vent plate;

[0011] A movable column is slidably connected to the cylinder body, and a first spring is fixedly connected inside the movable column, with the top end of the first spring fixedly connected to the inner top surface of the cylinder body.

[0012] A blocking plate is fixedly connected inside the main body. A circular hole is opened in the blocking plate, and the bottom end of the movable column is movably blocked in the circular hole.

[0013] Preferably, the number of output heads is set to multiple, and the multiple output heads are arranged around the central axis of the annular pipe.

[0014] Preferably, the pressure relief assembly includes:

[0015] The column body has a pressure relief hole extending through its exterior;

[0016] A telescopic rod, which is fixedly connected to the column body, and a second spring is provided on the outer sleeve of the telescopic rod;

[0017] A piston is fixedly connected to the bottom end of a telescopic rod and slidably connected to a cylinder.

[0018] Preferably, the number of the annular pipe, the output head and the pressure relief assembly is set to multiple sets, and each set of pressure relief assemblies is fixedly connected to a pressure relief chamber, and a pressure relief pipe is connected through the pressure relief chamber.

[0019] Preferably, each of the plurality of annular pipes is connected to a gas supply pipe, the plurality of gas supply pipes are connected in parallel to a connecting pipe, and a pump body is fixedly connected to one end of the connecting pipe.

[0020] Preferably, a filter box is fixedly installed on one side of the pump body.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By setting up annular pipes, multiple annular pipes are connected in parallel through multiple gas supply pipes and then fixedly installed inside the incinerator. Since the multiple annular pipes are set up in a ring, and the oxygen supply output head is arranged around the central axis of the annular pipes, oxygen can be output evenly, avoiding incomplete combustion in local areas and increasing the risk of explosion.

[0023] 2. By setting an output head, when the output head outputs oxygen, the oxygen pushes the movable column to slide upward in the cylinder, the round hole is opened, and the oxygen can enter the head body through the round hole, and then be discharged into the incinerator through the vent hole of the vent plate. When the oxygen is cut off, the movable column returns to its original position due to the elastic force of the first spring, blocking the round hole, which can prevent backfire and explosion.

[0024] 3. By setting up a pressure relief component, when the pressure in the annular pipe increases suddenly, it will push the piston to rise. As the piston rises, multiple pressure relief holes will be released, and oxygen can be discharged from the pressure relief holes into the pressure relief chamber, and then discharged through the pressure relief pipe to relieve pressure and prevent explosion.

[0030] 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.

[0031] Example 1

[0032] like Figure 1-4 As shown, in this embodiment, an oxygen supply mechanism for an incinerator includes an annular pipe 1, with an output head 2 for preventing backfire disposed on the inner side of the annular pipe 1; and a pressure relief assembly 3 disposed on the outer side of the annular pipe 1 for pressure relief.

[0033] The output head 2 includes: a head body 21, a vent plate 211 fixedly connected inside the head body 21, and multiple vent holes 212 opened inside the vent plate 211; a cylinder 22, which is fixedly connected inside the vent plate 211; a movable column 23, which is slidably connected inside the cylinder 22, and a first spring 231 is fixedly connected inside the movable column 23, with the top end of the first spring 231 fixedly connected to the inner top surface of the cylinder 22; and a blocking plate 24, which is fixedly connected inside the main body, and a circular hole 241 is opened inside the blocking plate 24, with the bottom end of the movable column 23 movably blocking the circular hole 241; the number of output heads 2 is set to multiple, and the multiple output heads 2 are arranged around the central axis of the annular pipe 1.

[0034] In this embodiment, the telescopic rod 32 is filled with a damping medium to prevent repeated vibrations.

[0035] In practice, multiple annular pipes 1 are connected in parallel through multiple gas supply pipes 5 and then fixedly installed inside the incinerator. Since the multiple annular pipes 1 are arranged in a ring and the oxygen supply output head 2 is arranged around the central axis of the annular pipes 1, oxygen can be output evenly, avoiding incomplete combustion in local areas and increasing the risk of explosion.

[0036] At the same time, when the output head 2 outputs oxygen, the oxygen pushes the movable column 23 to slide upward in the cylinder 22, and the round hole 241 is opened. The oxygen can enter the head body 21 through the round hole 241 and then be discharged into the incinerator through the vent hole 212 of the vent plate 211. When the oxygen is cut off, the movable column 23 returns to its original position under the elastic force of the first spring 231, blocking the round hole 241, which can prevent backfire and explosion.

[0037] Example 2

[0038] like Figure 4 As shown, in this embodiment, the pressure relief assembly 3 includes: a column 31 with a pressure relief hole 311 extending through it; a telescopic rod 32 fixedly connected inside the column 31, with a second spring 321 sleeved on the telescopic rod 32; a piston 33 fixedly connected to the bottom end of the telescopic rod 32 and slidably connected inside the column 31; multiple pressure relief assemblies 3 are fixedly connected to pressure relief chambers 4, with pressure relief pipes 41 extending through them; multiple annular pipes 1 are all connected to gas supply pipes 5, and multiple gas supply pipes 5 are connected in parallel to a connecting pipe 51, with a pump body 6 fixedly connected to one end of the connecting pipe 51; and a filter box 7 is fixedly installed on one side of the pump body 6.

[0039] In practice, when the pressure inside the annular pipe 1 increases suddenly, it will push the piston 33 to rise. As the piston 33 rises, multiple pressure relief holes 311 will leak out, and oxygen can be discharged from the pressure relief holes 311 into the pressure relief chamber 4, and then discharged through the pressure relief pipe 41 to relieve pressure and prevent explosion.

[0040] Working principle: Multiple annular pipes 1 are connected in parallel through multiple gas supply pipes 5 and then fixedly installed inside the incinerator. Since the multiple annular pipes 1 are arranged in a ring, and the oxygen supply output head 2 is arranged around the central axis of the annular pipe 1, oxygen can be output evenly, avoiding incomplete combustion in local areas and increasing the risk of explosion. At the same time, when the output head 2 outputs oxygen, the oxygen pushes the movable column 23 to slide upward in the cylinder 22, opening the round hole 241. The oxygen can enter the head body 21 through the round hole 241 and then be discharged into the incinerator through the vent hole 212 of the vent plate 211. When the oxygen is cut off, the movable column 23 returns to its original position under the elastic force of the first spring 231, blocking the round hole 241, which can prevent backfire and explosion. When the pressure in the annular pipe 1 increases suddenly, it will push the piston 33 to rise. The piston 33 rises and leaks multiple pressure relief holes 311. The oxygen can then be discharged from the pressure relief holes 311 into the pressure relief chamber 4, and then discharged through the pressure relief pipe 41 to relieve pressure and prevent explosion.
