Description

Technical Field

[0001] The present application relates to the technical field of automatic drainage structures, and in particular to an automatic drainage structure for a negative pressure pipeline of an incinerator. Background Art

[0002] An incinerator, also known as an incinerator, is an environmentally friendly device that is mainly used to incinerate waste gas, waste liquid, solid waste, medical waste, domestic waste, animal carcasses, etc. at high temperatures to achieve waste reduction and harmless treatment, and can also recover part of the heat energy of the incineration medium.

[0003] The existing Chinese patent publication number CN221403096U discloses a heat storage type thermal incinerator exhaust gas treatment device, including an incinerator, an exhaust pipe fixedly installed on the right side of the bottom of the incinerator, a first pipe fixedly installed on the left side of the bottom of the incinerator, an input end of the first pipe fixedly connected to a filter box, a second pipe fixedly installed on the left wall of the filter box, an input end of the second pipe fixedly connected to a purification box, an air inlet pipe fixedly installed on the left wall of the purification box, and a water circulation component for filtering water provided on the purification box.

[0004] In incinerators, the pipes in front of the air intake fans operate under negative pressure. In high humidity or rainy weather, water can accumulate in the pipes, flowing through the pipes into the fans and into the furnace, causing rapid corrosion of the furnace walls and cooling inside the furnace. Therefore, drainage is necessary. A drain pipe and a valve are typically installed at the lowest end of the air intake pipe in front of the fan for regular drainage, and the valve is opened when drainage is required. However, due to weather conditions, the amount of water in the pipes varies. If the water volume exceeds the collection tank, water will also enter the fan and be blown into the tank if it is not drained in time. During operation, the valve is closed to maintain negative pressure, and draining the accumulated water requires manual labor, which is inconvenient. Utility Model Content

[0005] The purpose of this application is to provide an automatic drainage structure for a negative pressure pipe of an incinerator, in order to automatically drain the accumulated water in the drainage pipe.

[0006] The automatic drainage structure of the negative pressure pipe of an incinerator provided in the present application adopts the following technical solution: it includes a mounting ring for being sleeved on the drainage pipe and a fixing assembly for fixing the mounting ring on the drainage pipe, and the mounting ring is rotatably connected to a cover plate for covering the opening of the drainage pipe.

[0007] By adopting this technical solution, the mounting ring is attached to the drainpipe via a fixing assembly. When the incinerator's fan is running, the negative pressure causes the cover plate to rotate, causing it to be sucked into the drainpipe opening, creating a seal and maintaining internal negative pressure. When water accumulates within the drainpipe to a certain level, the weight of the accumulated water presses open the cover plate, separating it from the drainpipe and allowing the accumulated water to flow out through the gap between the two. After the water flows out, the cover plate is sucked back into the drainpipe opening, and this cycle repeats, achieving automatic drainage.

[0008] Optionally, the cover plate is connected to a sealing rubber gasket for covering the opening of the drain pipe.

[0009] By adopting the above technical solution, the sealing rubber gasket can effectively prevent liquid or gas from leaking from the opening of the drain pipe, improve the sealing performance, and maintain the internal negative pressure state.

[0010] Optionally, the sealing rubber pad is detachably connected to the cover plate via a locking piece.

[0011] By adopting the above technical solution, it is easy to replace sealing rubber pads of different sizes to be suitable for drainage pipes with different inner diameters.

[0012] Optionally, the mounting ring is an elastic ring, and the mounting ring is provided with a notch. The fixing assembly includes two fixing plates connected to the mounting ring and a fixing structure for driving the two fixing plates to move toward each other, the fixing structure is connected to the fixing plates, and the notch is located between the two fixing plates.

[0013] By adopting the above technical solution, the mounting ring is placed on the drain pipe, and the two fixing plates are driven to move toward each other through the fixed structure. The mounting ring is elastically deformed under pressure and maintains a tendency to elastically reset. The mounting ring is clamped on the drain pipe, thereby improving the efficiency of the installation of the mounting ring.

[0014] Optionally, the fixing structure includes a first bolt connected to the two fixing plates and a first nut threadedly connected to the first bolt, and both fixing plates are provided with a mounting hole for the first bolt to pass through.

[0015] By adopting the above technical solution, one end of each first bolt passes through the mounting hole, and the first nut is threaded onto the first bolt. The first nut abuts the corresponding fixing plate and drives the fixing plate toward the other fixing plate. The mounting ring is elastically deformed under pressure and maintains an elastic return tendency, facilitating installation of the mounting ring on the drain pipe. Loosening the first nut elastically returns the mounting ring to its original position, separating the mounting ring from the drain pipe for easy removal.

[0016] Optionally, the cover plate is provided with a connecting plate, the connecting plate is connected to a rotating plate, and the rotating plate is rotatably connected to the first bolt.

[0017] By adopting the above technical solution, when the cover plate rotates, the cover plate rotates around the first bolt without the need for other rotating rods, thus saving materials.

[0018] Optionally, the rotating plate is provided with a waist-shaped hole for rotationally engaging with the first bolt.

[0019] By adopting the above technical solution, even if the mounting ring and the first bolt are not installed in relatively precise positions, the cover plate can be moved toward the direction close to the drain pipe, so that the cover plate seals the opening of the drain pipe.

[0020] Optionally, the fixing structure includes a threaded rod rotatably connected to one of the fixing plates and a second nut threadedly connected to the threaded rod, and both fixing plates are provided with grooves for rotatably cooperating with the threaded rod.

[0021] By adopting the above technical solution, the threaded rod is rotated so that the threaded rods are both stuck in the two grooves, and the second nut is rotated so that the second nut abuts against the corresponding fixing plate and drives the fixing plate to move toward the other fixing plate, thereby fixing the mounting ring to the drain pipe.

[0022] Optionally, a support rod is connected to a side of the connecting plate close to the first bolt, and the support rod is connected to a counterweight.

[0023] By adopting the above technical solution, the counterweight block increases the weight of the rotating plate near the first bolt end, reducing the distance between the cover plate and the drain pipe, making it easier for the cover plate to be adsorbed at the opening of the drain pipe.

[0024] Optionally, the counterweight is threadedly connected to the support rod.

[0025] By adopting the above technical solution, the counterweight block is threadedly connected to the support rod, which makes it easy to adjust the distance between the counterweight block and the connecting plate, and even to adjust the angle between the cover plate and the drain pipe.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the incinerator's fan is running, the negative pressure drives the cover plate to rotate, causing it to be sucked into the drainpipe opening, creating a seal and maintaining internal negative pressure. When water accumulates inside the drainpipe, the weight of the accumulated water pushes the cover plate open, separating it from the drainpipe and allowing the accumulated water to flow out through the gap between the two. After the water flows out, the cover plate is sucked back into the drainpipe opening, and this cycle repeats, achieving automatic drainage.

[0028] 2. Even if the mounting ring and the first bolt are not installed at a relatively precise position, the cover plate can be moved toward the drain pipe so that the cover plate seals the opening of the drain pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0037] The embodiment of the present application discloses an automatic drainage structure for a negative pressure pipe of an incinerator.

[0038] Combine Figure 1 and Figure 2As shown, the device comprises a mounting ring 2 that is sleeved on a drain pipe 1 and a fixing assembly 3 that secures the mounting ring 2 to the drain pipe 1. A control valve 11 is fixedly connected to the drain pipe 1. When the incinerator is not in use, the control valve 11 is closed to prevent dust from entering the incinerator through the drain pipe 1. The mounting ring 2 is an elastic ring made of an elastic material capable of elastic deformation. A notch 21 is defined in the mounting ring 2. The fixing assembly 3 comprises two fixing plates 31 relatively fixedly connected to the outer circumference of the mounting ring 2, and a fixing structure 32 for driving the two fixing plates 31 toward each other. The notch 21 is located between the two fixing plates 31.

[0039] Combine Figure 2 and Figure 3 As shown, the fixing structure 32 includes a first bolt 321 connected to the two fixing plates 31 and a first nut 322 threadedly connected to the first bolt 321. Both fixing plates 31 are provided with a mounting hole for the first bolt 321 to pass through. The mounting ring 2 is rotatably connected to a cover plate 4 for covering the opening of the drain pipe 1. A connecting plate 41 is provided on the side of the cover plate 4 close to the mounting ring 2. Two rotating plates 42 are provided on the side of the connecting plate 41 close to the first bolt 321. The two rotating plates 42 are integrally formed with the connecting plate 41, and the connecting plate 41 is integrally formed with the cover plate 4. Both rotating plates 42 are provided with a waist-shaped hole 421 for rotating with the first bolt 321. A sealing gasket 5 is detachably connected to the side of the cover plate 4 close to the mounting ring 2. The sealing gasket 5 is connected to the cover plate 4 via a locking member 51, which is a bolt. A support rod 43 is fixedly connected to one side of the connecting plate 41 close to the first bolt 321. The support rod 43 and the connecting plate 41 are integrally formed. An end of the support rod 43 away from the connecting plate 41 is fixedly connected to a boss 431. The radius of the boss 431 is larger than the radius of the support rod 43. The support rod 43 is detachably connected to a counterweight block 6. The counterweight block 6 is provided with a through hole 61 for the boss 431 to pass through.

[0040] The implementation principle of the automatic drainage structure of the negative pressure pipe of an incinerator in the embodiment of the present application is as follows:

[0041] When the incinerator's fan operates, negative pressure drives cover plate 4 to rotate, causing it to attach to the opening of drain pipe 1, creating a seal and maintaining negative pressure. When water accumulates within drain pipe 1 to a certain level, the weight of the accumulated water pushes cover plate 4 apart, allowing it to flow out through the gap between them. After the water flows out, cover plate 4 is reattached to the opening of drain pipe 1, and this cycle repeats, achieving automatic drainage.
