Description

Technical Field

[0001] This utility model relates to the technical field of shock wave jetting equipment for waste-to-energy plants, specifically to a through-wall sleeve sealing device for shock wave jetting equipment in waste-to-energy plants. Background Technology

[0002] In waste-to-energy plants, the boiler interior accumulates large amounts of dust and soot due to the long-term combustion of waste, especially forming a hard ash layer on boiler pipes and heating surfaces. Shockwave cleaning equipment is often used for ash removal. This equipment generates high-energy shock waves to forcefully dislodge the accumulated ash from inside the boiler.

[0003] Currently, shockwave purging equipment on the market typically uses wall sleeves that are directly welded to the boiler wall. While this provides a stable seal in the short term, it has several drawbacks. Once blockage occurs, cleaning and maintenance become extremely difficult, usually requiring shutdown and removal of the welded area. This not only consumes significant manpower and time but also leads to prolonged boiler downtime, reducing the operational efficiency of the waste-to-energy plant. Furthermore, because the welded sleeve method lacks quick disassembly and cleaning capabilities, frequent cleaning requirements increase equipment wear and tear, impacting the lifespan of the shockwave purging equipment.

[0004] Therefore, a wall-penetrating sleeve sealing device for shock wave jetting equipment in waste-to-energy plants is needed to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device for the through-wall sleeve of the shock wave blowing equipment in a waste-to-energy plant, so as to solve the problem mentioned in the background art that the through-wall sleeve is difficult to disassemble and clean to maintain the sealing performance and prevent blockage of the pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a through-wall sleeve sealing device for a shock wave jetting equipment in a waste-to-energy plant, comprising a boiler wall and a sealing pipe assembly. The sealing pipe assembly is welded inside the boiler wall. The input end of the sealing pipe assembly is connected to a jetting pipe, which is connected to a connecting pipe. The connecting pipe is installed at the bottom of the shock wave jetting device. The input end of the sealing pipe assembly is connected to a jetting head. A fixing plate is welded to the outer wall of the boiler wall. A set of push rods is movably connected inside the boiler wall. Four sets of corresponding through-wall holes are opened inside the boiler wall. The push rods extend through the through-wall holes to the inside of the through-wall holes and are welded to the fixing seat.

[0007] Preferably, a limiting block is machined at one end of the push rod located on the outside of the boiler wall, and the size of the limiting block is larger than the through hole.

[0008] Preferably, a fixing bolt is fixedly connected between the push rod and the fixing plate, and the fixing bolt is fixed to the outside of the through-wall hole.

[0009] Preferably, a connecting seat is welded at the inlet of the blow nozzle, and the connecting seat is embedded in the sealing tube assembly to form a passage with the blow pipe.

[0010] Preferably, the fixed base has two sets of foot grooves, and the blow nozzle has two sets of foot rods welded to it, with the foot rods movably connected to the foot grooves.

[0011] Preferably, a spring is welded between the foot rod and the fixed base, and the foot rod is "L" shaped.

[0012] Preferably, the sealing tube assembly is a rigid metal sleeve, and rubber bushings are nested at both ends of the sealing tube assembly.

[0013] Preferably, the fixing plate is a square metal sheet, and the installation positions are evenly distributed on the boiler wall.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the wall sleeve sealing device of the shock wave jetting equipment in the waste-to-energy plant not only achieves maintenance without removing all the jetting devices and maintaining the sealing performance, thus mitigating the strong shock wave, but also achieves a tight connection and is not prone to leakage.

[0015] (1) The shock wave jet is installed on the outer wall of the boiler by means of a fixed plate, fixed bolts, push rod and wall hole. It is connected to the jet head through the jet pipe to form a jet channel. During daily maintenance, the operator can first remove the fixed bolts fixed at the fixed plate and push the push rod inward along the wall hole so that the connecting seat of the jet head is disconnected from the sealing pipe group. This operation will open one end of the sealing pipe group. The cleaning personnel do not need to enter the boiler to use cleaning tools to unclog the inside of the sealing pipe group to prevent blockage. After cleaning, the push rod is pulled back and fixed to the fixed plate on the outer wall by the fixed bolts so that the connecting seat of the jet head is tightly connected to the sealing pipe group again. The maintenance work can be completed without removing the entire jet device, avoiding equipment wear and time waste caused by frequent disassembly and assembly, and effectively solving the problem of difficult cleaning and maintenance of garbage boiler pipelines.

[0016] (2) By setting up a connecting seat, a fixed seat, a foot rod, a foot groove, and a spring, the nozzle is fixed to the fixed seat through the connecting seat. Two sets of foot rods are embedded in the foot groove to provide fine-tuning support. The spring, as an elastic adjustment element, can maintain the small displacement of the nozzle during shock wave injection, thereby absorbing part of the impact force. When the shock wave injector generates a strong shock wave that is sprayed onto the inner wall of the boiler, the nozzle moves slightly to the right to buffer the impact force. However, since the connecting seat is still firmly embedded in the sealing pipe group, the pipe sealing will not be damaged. This not only improves the stability of the shock wave injector but also ensures the durability of the injection equipment during long-term high-frequency operation.

[0017] (3) By setting up a sealing pipe assembly and rubber bushing, the sealing pipe assembly adopts an inner and outer double-sleeve structure. The two sets of pipe openings inside are respectively embedded with rubber bushings. One end is connected to the feed port of the injection pipe, and the other end is connected to the connection seat of the injection head to ensure the tightness of the connection. When the shock wave jet cleaner cleans the ash inside the boiler, it can effectively prevent the gas leakage problem caused by high pressure impact during injection. It can prevent the pipe joint from aging or deforming in harsh environments of high temperature and high pressure. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4An embodiment of this utility model provides a shock wave jetting equipment through-wall sleeve sealing device for a waste-to-energy plant, including a boiler wall 9 and a sealing pipe assembly 5. The sealing pipe assembly 5 is welded inside the boiler wall 9. The input end of the sealing pipe assembly 5 is connected to a jetting pipe 2, which is connected to a connecting pipe 1. The connecting pipe 1 is installed at the bottom of the shock wave jetting device. The input end of the sealing pipe assembly 5 is connected to a jetting head 6. A fixing plate 4 is welded to the outer wall of the boiler wall 9. A set of push rods 3 are movably connected inside the boiler wall 9. Four sets of corresponding through-wall holes 10 are opened inside the boiler wall 9. The push rods 3 pass through the through-wall holes 10, extend to the inside of the through-wall holes 10, and are welded to a fixing seat 8. A limit block 12 is processed at one end of the push rod 3 located outside the boiler wall 9. The size of the limit block 12 is larger than the through-wall hole 10. A fixing bolt 11 is fixedly connected between the push rod 3 and the fixing plate 4. The fixing bolt 11 is fixed outside the through-wall hole 10.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the shockwave jet cleaner is installed on the outer wall of the boiler wall 9 and is connected to the jet head 6 through the jet pipe 2 to form a jet channel. During routine maintenance, the operator can first remove the fixing bolt 11 fixed at the fixing plate 4 and push the push rod 3 inward along the through hole 10 to disengage the connecting seat 7 of the jet head 6 from the sealing pipe assembly 5. This operation will open one end of the sealing pipe assembly 5, allowing the cleaning personnel to use cleaning tools to unclog the inside of the sealing pipe assembly 5 without entering the boiler to prevent blockage. After cleaning, the push rod 3 is pulled back and re-fixed to the outer wall fixing plate 4 through the fixing bolt 11, so that the connecting seat 7 of the jet head 6 and the sealing pipe assembly 5 are tightly connected again. Maintenance work can be completed without removing the entire jet device, avoiding equipment wear and time waste caused by frequent disassembly and assembly, and effectively solving the problem of difficult cleaning and maintenance of waste boiler pipelines.

[0026] A connecting seat 7 is welded at the inlet of the blow nozzle 6. The connecting seat 7 is embedded in the sealing tube assembly 5 and forms a passage with the blow pipe 2. Two sets of foot grooves 15 are opened in the fixed seat 8. Two sets of foot rods 13 are welded at the blow nozzle 6. The foot rods 13 are movably connected in the foot grooves 15. Springs 14 are welded between the foot rods 13 and the fixed seat 8. The foot rods 13 are "L" shaped.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the nozzle 6 is fixed to the fixed seat 8 via the connecting seat 7. Two sets of foot rods 13 are embedded in the foot groove 15 to provide fine-tuning support. The spring 14 serves as an elastic adjustment element, which can maintain the slight displacement of the nozzle 6 during shock wave injection, thereby absorbing part of the impact force. When the shock wave injector generates a powerful shock wave that is sprayed onto the inner wall of the boiler, the nozzle 6 moves slightly to the right to buffer the impact force. However, since the connecting seat 7 is still firmly embedded in the sealing pipe assembly 5, the pipe sealing will not be damaged. This not only improves the stability of the shock wave injector but also ensures the durability of the injection equipment during long-term high-frequency operation.

[0028] The sealing pipe assembly 5 is a rigid metal sleeve, and rubber bushings 16 are nested at the two pipe openings of the sealing pipe assembly 5. The fixing plate 4 is a square metal piece, and the installation positions are evenly distributed at the boiler wall 9.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, the sealing pipe assembly 5 adopts a double-layer structure with inner and outer sleeves. The two sets of pipe openings inside are respectively embedded with rubber bushings 16. One end is connected to the feed port of the blow pipe 2, and the other end is tightly connected to the connecting seat 7 of the blow head 6 to ensure the tightness of the connection. When the shock wave blower cleans the ash inside the boiler, it can effectively prevent gas leakage caused by high pressure impact during the blow. It can prevent the pipe joints from aging or deforming in harsh environments of high temperature and high pressure.

[0030] Working Principle: The shockwave jet cleaner is installed on the outer wall of the boiler wall 9 and is connected to the jet head 6 through the jet pipe 2 to form a jet channel. During routine maintenance, the operator can first remove the fixing bolts 11 fixed to the fixing plate 4, and push the push rod 3 inward along the through hole 10, so that the connecting seat 7 of the jet head 6 is disconnected from the sealing tube assembly 5. This operation will open one end of the sealing tube assembly 5, allowing the cleaning personnel to use cleaning tools to unclog the inside of the sealing tube assembly 5 without entering the boiler to prevent blockage. After cleaning, pull the push rod 3 back and fix it to the outer wall fixing plate 4 through the fixing bolts 11, so that the connecting seat 7 of the jet head 6 and the sealing tube assembly 5 are tightly connected again. Maintenance work can be completed without removing the entire jetting device. The jet head 6 is connected to the fixing seat through the connecting seat 7. 8. Fixed by two sets of foot rods 13 embedded in foot grooves 15 to provide fine-tuning support. Spring 14 serves as an elastic adjustment element, which can maintain a slight displacement of the nozzle 6 during shock wave blowing, thereby absorbing part of the impact force. When the shock wave blower generates a strong shock wave that sprays onto the inner wall of the boiler, the nozzle 6 moves slightly to the right to buffer the impact force. However, since the connecting seat 7 is still firmly embedded in the sealing pipe assembly 5, the pipe sealing performance will not be damaged. The sealing pipe assembly 5 adopts a double-set structure with inner and outer sleeves. Rubber bushings 16 are embedded in the two sets of pipe openings inside. One end is connected to the feed port of the blowing pipe 2, and the other end is tightly connected to the connecting seat 7 of the nozzle 6 to ensure the tightness of the connection. When the shock wave blower cleans the ash inside the boiler, it can effectively prevent gas leakage caused by high-pressure impact during blowing.
