Description

Technical Field

[0001] This utility model relates to the field of incinerator feeding technology, specifically to a feeding device based on an RTO regenerative thermal oxidizer. Background Technology

[0002] With the rapid development of industry, various enterprises generate a large amount of pollutants such as organic waste gas, waste liquid and solid waste during the production process. Regenerative thermal oxidizers (RTO) have emerged as a highly efficient waste gas and waste treatment equipment.

[0003] However, the efficient operation of a regenerative thermal oxidizer (RTO) relies on a stable and reasonable feeding system. In traditional feeding device designs, manual feeding or belt conveyor methods are often used, which makes it difficult to accurately control the material conveying speed and volume. Either the material supply is insufficient, failing to fully utilize the incinerator's processing capacity, or excessive material enters, causing instability in the incinerator's temperature, pressure, and other operating conditions. In addition, the simple and direct feeding methods of the past easily cause material to accumulate locally in the furnace. The accumulated areas cannot burn completely due to the excessive thickness of the material. The unburned material will produce a large amount of harmful gases, reducing processing efficiency and increasing the difficulty and cost of subsequent exhaust gas treatment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a feeding device based on an RTO regenerative thermal oxidizer, comprising: a feeding device, wherein a feeding structure is slidably connected to the outer wall of the feeding device; the feeding device includes a feeding cylinder, wherein a screw rod is slidably connected to the inner wall of the feeding cylinder, a feeding port is opened on the outer wall of the bottom of the feeding cylinder, a feeding hopper is fixedly connected to the outer wall of the feeding cylinder near the feeding port, a discharging port is opened on the outer wall of the top of the feeding cylinder, a discharging hopper is fixedly connected to the outer wall of the feeding cylinder near the discharging port, limit rods are symmetrically fixedly connected to the outer wall of the bottom of the discharging hopper, a motor is rotatably connected to the outer wall of the bottom of the screw rod, a base plate is fixedly connected to the outer wall of the bottom of the motor, and a support frame is fixedly connected to the outer wall of the feeding cylinder.

[0005] Preferably, the feed hopper is located outside the feed inlet, and the discharge hopper is located outside the discharge outlet. The motor drives the screw rod to slide and rotate along the inside of the feed cylinder, and the material can be conveyed from the feed inlet to the discharge outlet by relying on the screw blades.

[0006] Preferably, the feeding structure includes a feeding plate, with baffles symmetrically fixedly connected to the outer wall of the feeding plate, slide rods symmetrically slidably connected to the inner wall of the bottom of the feeding plate, and tension springs symmetrically fixedly connected to the outer wall of the bottom of the feeding plate.

[0007] Preferably, the outer wall at the bottom of the slide bar is fixedly connected to the furnace body, the outer wall at the top of the furnace body is provided with a feeding port, the outer wall at the top of the furnace body is fixedly connected to the motor, the outer wall of the motor is rotatably connected to the cam, and the feeding plate is positioned above the feeding port.

[0008] Preferably, the outer wall of the top of the furnace body is fixedly connected to the outer wall of the side of the tension spring away from the material feeding plate, and the outer wall of the cam is slidably connected to the outer wall of the bottom of the material feeding plate and the outer wall of the top of the furnace body. The motor drives the cam to rotate. As the cam rotates, its protruding part will periodically push up the material feeding plate. When the cam protruding part contacts the material feeding plate and pushes it up, the tension spring is stretched. When the cam protruding part rotates, the material feeding plate falls back under the restoring force of the tension spring. Through the continuous rotation of the cam, the material feeding plate will move up and down to form vibration.

[0009] Preferably, the outer wall of the limiting rod is slidably connected to the inner wall of the feeding plate on the side away from the slide rod, which guides and limits the sliding of the feeding plate. The outer walls of the support frame and the base plate are fixedly connected to the outer wall of the furnace body, which connects the feeding device and the furnace body, making the entire feeding device structure more compact and stable.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a feeding structure, uses a motor to drive the cam to rotate, and through the cooperation between the slide rod and the tension spring, the feeding plate can generate up-and-down reciprocating vibration, realizing the intermittent and uniform entry of materials into the furnace body. This uniform material distribution method avoids the large amount of material entering the furnace body directly, causing local accumulation, and improves the completeness of material combustion.

[0012] 2. This utility model, by setting up a feeding device, adopts a structure in which a screw rod and a feeding cylinder cooperate, and the motor drives the screw rod to rotate, which can accurately control the material conveying speed and conveying volume, ensuring that the incinerator is always in the best operating state, improving the utilization efficiency of materials and heat energy, and reducing energy waste.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example:

[0021] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a feeding device based on an RTO regenerative thermal oxidizer, comprising: a feeding device 1, with a feeding structure 2 slidably connected to the outer wall of the feeding device 1; the feeding device 1 includes a feeding cylinder 11, with a screw rod 12 slidably connected to the inner wall of the feeding cylinder 11, a feeding port 13 opened on the outer wall of the bottom of the feeding cylinder 11, a feeding hopper 14 fixedly connected to the outer wall of the feeding cylinder 11 near the feeding port 13, a discharging port 15 opened on the outer wall of the top of the feeding cylinder 11, a discharging hopper 16 fixedly connected to the outer wall of the feeding cylinder 11 near the discharging port 15, limit rods 17 symmetrically fixedly connected to the outer wall of the bottom of the discharging hopper 16, a motor 18 rotatably connected to the outer wall of the bottom of the screw rod 12, a base plate 19 fixedly connected to the outer wall of the bottom of the motor 18, and a support frame 191 fixedly connected to the outer wall of the feeding cylinder 11.

[0022] The feed hopper 14 is located outside the feed inlet 13, and the discharge hopper 16 is located outside the discharge outlet 15. The motor 18 drives the screw rod 12 to slide and rotate along the inside of the feed cylinder 11. The material can be conveyed from the feed inlet 13 to the discharge outlet 15 by relying on the screw blades.

[0023] The feeding structure 2 includes a feeding plate 21, with baffles 22 symmetrically fixedly connected to the outer wall of the feeding plate 21, slide rods 23 symmetrically slidably connected to the inner wall of the bottom of the feeding plate 21, and tension springs 24 symmetrically fixedly connected to the outer wall of the bottom of the feeding plate 21.

[0024] The outer wall at the bottom of the slide bar 23 is fixedly connected to the furnace body 25. The outer wall at the top of the furnace body 25 is provided with a feeding port 26. The outer wall at the top of the furnace body 25 is fixedly connected to the motor 27. The outer wall of the motor 27 is rotatably connected to the cam 28, and the feeding plate 21 is located above the feeding port 26.

[0025] The outer wall of the top of the furnace body 25 is fixedly connected to the outer wall of the side of the tension spring 24 away from the material plate 21. The outer wall of the cam 28 is slidably connected to the outer wall of the bottom of the material plate 21 and the outer wall of the top of the furnace body 25. The motor 27 drives the cam 28 to rotate. As the cam 28 rotates, its protruding part will periodically push up the material plate 21. When the protruding part of the cam 28 contacts the material plate 21 and pushes it up, the tension spring 24 is stretched. When the protruding part of the cam 28 rotates, the material plate 21 falls back under the restoring force of the tension spring 24. Through the continuous rotation of the cam 28, the material plate 21 will move up and down to form vibration.

[0026] The outer wall of the limiting rod 17 is slidably connected to the inner wall of the feeding plate 21 on the side away from the slide rod 23, which guides and limits the sliding of the feeding plate 21. The outer walls of the support frame 191 and the base plate 19 are fixedly connected to the outer wall of the furnace body 25, which connects the feeding device 1 and the furnace body 25, making the entire feeding device structure more compact and stable.

[0027] Working principle: First, the material enters the feeding cylinder 11 from the feeding port 13 through the feeding hopper 14 in the feeding device 1. Then, the motor 18 on the base plate 19 is started, which drives the screw rod 12 to slide and rotate inside the feeding cylinder 11. When the screw rod 12 rotates inside the feeding cylinder 11, it uses the screw blades to transport the material from the feeding port 13 to the discharge port 15. During the conveying process, the material is gradually lifted and pushed upward in the feeding cylinder 11, and finally discharged from the discharge port 15 through the discharge hopper 16. The support frame 191 on the outer wall of the feeding cylinder 11 is fixedly connected to the outer wall of the furnace body 25, which serves to connect the feeding device 1 and the furnace body 25, making the entire feeding device structure more compact and stable.

[0028] After the material is discharged from the discharge hopper 16, it falls onto the feed plate 21 of the feeding structure 2. The feed plate 21 has baffles 22 on both sides to prevent material spillage. At this time, the motor 27 at the top of the furnace body 25 drives the cam 28 to rotate. Since the outer wall of the cam 28 is slidably connected to the outer wall at the bottom of the feed plate 21 and the outer wall at the top of the furnace body 25, as the cam 28 rotates, its protruding part periodically pushes up the feed plate 21. When the protruding part of the cam 28 contacts and pushes up the feed plate 21, the tension spring 24 is stretched, and the feed plate 21 slides upward along the slide rod 23. At the same time, the limiting rod 17 also slides against the feed plate 21, thus controlling the sliding of the feed plate 21. The cam 28 acts as a guide and limiter to ensure the stable movement of the feeding plate 21. When the cam 28 protrudes, the feeding plate 21 falls back under the restoring force of the tension spring 24. Through the continuous rotation of the cam 28, the feeding plate 21 will move up and down to form vibration, so that the material falling on the feeding plate 21 enters the furnace body 25 evenly through the feeding port 26 at the top of the furnace body 25, realizing the feeding process of the RTO regenerative incinerator. The vibration feeding method is conducive to the uniform distribution and full combustion of the material in the furnace body 25, and avoids the material falling directly into the furnace body 25 in large quantities, causing local accumulation and resulting in incomplete combustion of the material.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
