Description

Technical Field

[0001] The utility model relates to the technical field of waste gas incinerators, in particular to a fire arrester for waste gas incinerators. Background Art

[0002] Waste gas incinerator is a way to incinerate organic waste gas at high temperature. It increases the temperature of organic waste gas discharged from the production process and directly oxidizes and decomposes it at this high temperature. The heat of the high-temperature gas during oxidation is stored in the ceramic heat storage body and used to preheat the newly incoming organic waste gas, thereby saving the fuel consumption required for heating.

[0003] The prior art still has the following problems:

[0004] First, the existing fire-blocking devices for waste gas incinerators often block fire through a baffle or water sprinkling. When the flame touches the water, a larger flame may be generated. A single baffle is prone to generate a bellows that causes air circulation, making it impossible to directly block fire.

[0005] Secondly, the existing waste gas incinerator fire-blocking device cannot be quickly disassembled and installed. When the waste gas after incineration is fire-blocked, certain impurities are easily generated. Excessive impurities will cause the device to be unable to be used normally, which is not conducive to the long-term operation of the fire-blocking device.

[0006] In view of the above problems, the inventors proposed a flame arrester for a waste gas incinerator to solve the above problems. Utility Model Content

[0007] In order to solve the problem that the fire arrester cannot perform perfect and automated fire arrester and cannot be quickly disassembled and installed, the purpose of the utility model is to provide a fire arrester for a waste gas incinerator.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions: a flame arrester for a waste gas incinerator, comprising a flow box, a collecting bucket is detachably provided on the lower surface of the flow box, four support rods are fixedly connected to the lower surface of the flow box, and the four support rods are adapted to the collecting bucket, a collecting groove is provided inside the collecting bucket, a circular groove used in conjunction with the collecting groove is provided on the lower surface of the flow box, and the waste gas impurities generated in the flow box can directly fall into the interior of the collecting bucket, which is more adapted to the device, a motor is fixedly provided on the upper surface of the flow box, a main rod is fixedly connected to the output end of the motor, and the main rod passes through the flow box, an auxiliary rod is fixedly connected to the outer surface of the main rod, a first gear is fixedly provided on the lower end of the main rod, and the outer surface of the first gear meshes Two second gears are connected together, and a toothed plate is fixedly provided on the inner wall of the flow box. The outer surfaces of the two second gears are meshed with the inner surface of the toothed plate, so that the two rotating rods can be driven to rotate by starting the main rod. Rotating rods are inserted in the middle parts of the two second gears, so that the two rotating rods can be driven to rotate by starting the main rod. A connecting ring is sleeved on the outer surface of the two rotating rods, and a fixing rod is fixedly provided on the outer surface of the connecting ring. A blocking column is fixedly connected to the end of the fixing rod away from the connecting ring, which can achieve the effect of blocking the air inside the flow box, thereby preventing fire. Inlet pipes and outlet pipes are provided on the outer surfaces of both sides of the flow box, and the area of ​​the two blocking columns is the same as that of the inlet pipe and the outlet pipe, which can block the exhaust gas and is more suitable for the device.

[0009] Preferably, two insertion rods are fixedly provided on the upper surface of the collecting bucket, and the upper ends of the two insertion rods are fixedly connected to the limiting blocks. The upper surface of the collecting bucket is provided with two placement grooves, and the lower surfaces of the placement grooves are fixedly connected with springs, and the upper ends of the springs are fixedly connected with rectangular blocks. The lower surface of the flow box is provided with two limit grooves for cooperating with the limit blocks, and one side of the two limit grooves is provided with an arc groove for cooperating with the insertion rods, which can be rotated after the insertion of the insertion rods, so that the collecting bucket is more stable. The lower surface of the flow box is provided with two auxiliary grooves for cooperating with the rectangular blocks, and the two auxiliary grooves cooperate with the rectangular blocks and the springs to assist the connection between the flow box and the collecting bucket, making them tighter and more stable.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model sets a motor, starts the motor to drive the main rod and two rotating rods to rotate, thereby driving the barrier column to rotate. When the two barriers are aligned with the air inlet pipe and the air outlet pipe, the air inside the flow box is lost, and the flame cannot continue to burn without oxygen, thereby preventing fire;

[0012] 2. The utility model provides an insert rod and a rectangular block. The two insert rods rotate inside the limit and arc grooves. When the limit grooves are aligned with the limit blocks, the rectangular blocks are separated from the auxiliary grooves for disassembly. In other words, the disassembly and installation are more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] An air inlet pipe 111 and an air outlet pipe 112 are provided on the outer surfaces of both sides of the flow box 1 , and the areas of the two barrier columns 19 are the same as those of the air inlet pipe 111 and the air outlet pipe 112 .

[0028] Four support rods 3 are fixedly connected to the lower surface of the flow box 1, and the four support rods 3 are adapted to the collection barrel 2.

[0036] Working principle: When using this type of flame arrester for a waste gas incinerator, firstly, the waste gas generated by the incinerator is discharged into the interior of the flow box 1 through the air inlet pipe 111. When the waste gas generates sparks, the motor 11 is started, and the output end of the motor 11 drives the main rod 12 to rotate, thereby driving the first gear 15 to rotate, and the two second gears 16 meshing with the first gear 15 rotate inside the toothed plate 14.

When the two blocking columns 19 are aligned with the air inlet pipe 111 and the air outlet pipe 112, the interior of the flow box 1 The air in the part is lost, and the flame cannot continue to burn without oxygen, thereby preventing fire. When the exhaust gas burns, impurities are generated and fall into the collection groove 26 inside the collection barrel 2. By rotating the collection barrel 2, the two insertion rods 21 rotate inside the limit groove 41 and the arc groove 42. When the limit groove 41 is aligned with the limit block 22, the rectangular block 23 is separated from the auxiliary groove 4 for disassembly, and the impurities inside the collection groove 26 are taken out. When the collection barrel 2 needs to be installed, the rectangular block 23 and the lower surface of the flow box 1 are squeezed against each other and are located inside the placement groove 24. Under the action of the spring 25, when the rectangular block 23 is aligned with the auxiliary groove 4, the rectangular block 23 enters the auxiliary groove 4, thereby making the installation more stable.
