Description

Technical Field

[0001] This utility model relates to the field of waste treatment, specifically to an automatic scab removal device for use in waste incinerators. Background Technology

[0002] A waste incinerator is a device used to process waste. It converts waste into ash and flue gas through high-temperature combustion, achieving the harmlessness, volume reduction, and resource utilization of waste. During the operation of a waste incinerator, due to factors such as fuel characteristics, furnace temperature, air distribution, and flue gas flow characteristics, the fly ash produced by waste incineration will deposit, melt, and solidify in the furnace or on the heated surfaces, forming char, a phenomenon known as scab formation. Scab formation not only occupies furnace space and limits the contact area between waste and oxygen, leading to incomplete combustion, but may also cause uneven furnace temperature distribution, reducing the thermal efficiency of the incinerator, causing corrosion and wear of the internal furnace structure, and accelerating the aging and damage of the incinerator.

[0003] Existing methods for cleaning scabs typically involve manual labor combined with tools (high-pressure water guns, vibrators, etc.). However, due to the high height of the furnace, workers need to use stairs to clean the top of the furnace, resulting in low cleaning efficiency and incomplete cleaning. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic scab cleaning device for waste incinerators that can quickly clean scabs on the top of the furnace, thereby improving cleaning efficiency and cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a furnace body, within which a furnace chamber is provided. A cleaning chamber cover is provided on the top of the furnace body. A cleaning chamber communicating with the furnace chamber is located inside the cleaning chamber cover. The cleaning chamber is equipped with a cleaning head and an adjustment mechanism for adjusting the position and orientation of the cleaning head. The adjustment mechanism has an extended state where the cleaning head extends into the furnace chamber and a retracted state where the cleaning head is retracted into the cleaning chamber. The cleaning head is equipped with a camera, a high-pressure water nozzle connected to a water source, and a cleaning liquid nozzle connected to an acidic cleaning liquid source. A gate mechanism is provided on the top of the furnace body to separate the cleaning chamber from the furnace chamber when the adjustment mechanism is in the retracted state.

[0006] By adopting the above technical solution, when the waste incinerator is working, the cleaning head is retracted into the cleaning chamber, and the cleaning chamber and the furnace are separated by the gate mechanism. When cleaning is required, under the monitoring of the camera, the adjustment mechanism extends the cleaning head into the furnace and aims it at the position to be cleaned on the top of the furnace. First, acidic cleaning liquid is sprayed to soften and loosen the scabs, and then the scabs are washed with high-pressure water. After cleaning is completed, the adjustment mechanism retracts the cleaning head back into the cleaning chamber. The above structure has the following advantages: ① Automatic cleaning replaces manual cleaning, enabling accurate and comprehensive cleaning of hard-to-clean areas (top of the furnace), improving cleaning efficiency and effectiveness; ② Real-time transmission of close-up images by cameras makes remote operation more reliable; ③ The use of acidic cleaning solution (which can be low-solubility hydrochloric acid) combined with high-pressure water cleaning reduces the amount of acidic cleaning solution used, thus reducing the possibility of damage to the furnace; and high-pressure water can more easily remove scabs, reducing water consumption and saving water resources; ④ The addition of a gate mechanism protects the cleaning device, extends its service life, and prevents the leakage of heat and flue gas used for power generation, thus avoiding environmental pollution.

[0007] The present invention is further configured such that: the adjustment mechanism includes a main turntable rotatably mounted on the top of the cleaning chamber; a circumferential motor driving the main turntable to rotate is mounted above the cleaning chamber cover; a swing arm seat, a main swing arm hinged to the swing arm seat, and a main swing motor driving the main swing arm to swing up and down are mounted below the main turntable; multiple secondary swing arms are mounted below the swing end of the main swing arm, which are hinged end to end; an auxiliary swing motor driving the uppermost secondary swing arm to swing up and down is mounted at the swing end of the main swing arm; between adjacent secondary swing arms, a secondary swing motor driving the lower secondary swing arm to swing up and down is mounted at the lower end of the upper secondary swing arm; and an orientation motor driving the cleaning head to rotate is mounted at the lower end of the lowermost secondary swing arm.

[0008] By adopting the above technical solution, the horizontal rotation of the turntable, the up-and-down swing of the main swing arm, the up-and-down swing of the multi-section swing arm, and the rotation of the cleaning head enable precise and rapid large-range and multi-directional posture adjustment of the cleaning head, thereby meeting the cleaning needs of each surface and corner of the furnace top and further ensuring the cleaning effect.

[0009] The present invention is further configured such that: roller seats are respectively provided on both sides above the cleaning chamber cover; the roller seats are rotatably equipped with a pipe-retracting roller and a roller motor for driving the pipe-retracting roller to rotate; one of the pipe-retracting rollers is used to retract and extend the water supply hose connecting the water source and the high-pressure water nozzle; the other pipe-retracting roller is used to retract and extend the cleaning fluid hose connecting the acidic cleaning fluid source and the cleaning fluid nozzle; and a through hole is provided above the cleaning chamber cover for the water supply hose and the cleaning fluid hose to extend into the cleaning chamber.

[0010] By adopting the above technical solution and adding a roller seat, the hose is wound upwards while the adjusting mechanism retracts the cleaning head into the cleaning chamber, thus preventing the hose from being damaged when separated by the gate mechanism and extending the service life of the hose.

[0011] The present invention is further configured such that: a gate through hole is provided on the side of the cleaning chamber cover; the gate mechanism includes a gate, a U-shaped track plate and a gate motor; the U-shaped track plate is inverted and fixed above the furnace body and forms a gate guide channel opposite to the gate through hole with the upper end face of the furnace body; the gate slides in the gate guide channel and extends into the cleaning chamber through the gate through hole; a drive port connected to the gate guide channel is provided above the U-shaped track plate; a transmission rack opposite to the drive port is provided above the gate along the moving direction; the gate motor is fixed above the U-shaped track plate and drives a transmission gear that passes through the drive port and meshes with the transmission rack; when the gate moves, it has a separated state between the cleaning chamber and the furnace and an open state outside the cleaning chamber.

[0012] By adopting the above technical solution, the gate motor drives the transmission gear to rotate, and then drives the gate to move back and forth through the transmission rack, so as to realize the stable and accurate switching of the gate between the separated state and the open state, and further ensure that the cleaning device is not affected by the garbage incineration when it is not working, and that the smoke or heat generated by the garbage incineration will not leak out.

[0013] The present invention is further configured such that: multiple ball grooves are equidistantly arranged along the circumference above the main turntable, and each ball groove is provided with a ball that rolls and cooperates with the upper end surface of the cleaning chamber.

[0014] By adopting the above technical solution, ball bearings are added between the top of the main turntable and the upper end face of the cleaning chamber, making the rotation of the main turntable smoother and more sensitive, and further ensuring the speed and accuracy of the adjustment function.

[0024] like Figure 1 — Figure 7As shown in the figure, this utility model discloses an automatic scab cleaning device for waste incinerators, including a furnace body 1. The furnace body 1 in the figure is not the complete structure and is only for illustration. A furnace chamber 11 is provided inside the furnace body 1. A cleaning chamber cover 2 is provided on the top of the furnace body 1. A cleaning chamber 21 communicating with the furnace chamber 1 is provided inside the cleaning chamber cover 2. The cleaning chamber 21 is provided with a cleaning head 3 and an adjustment mechanism for adjusting the position and orientation of the cleaning head 3. The adjustment mechanism has an extended state in which the cleaning head 3 extends into the furnace chamber 11 and a retracted state in which the cleaning head 3 is retracted into the cleaning chamber 21. The cleaning head 3 is provided with a camera 31, a high-pressure water nozzle 32 connected to a water source, and a... The cleaning fluid nozzle 33 is connected to the acid cleaning fluid source. The top of the furnace body 1 is equipped with a gate mechanism that separates the cleaning chamber 21 and the furnace chamber 11 when the adjustment mechanism is in the recovery state. When the waste incinerator is working, the cleaning head 3 is recovered into the cleaning chamber 21, and the gate mechanism separates the cleaning chamber 21 and the furnace chamber 11. When cleaning is required, under the monitoring of the camera 31, the adjustment mechanism extends the cleaning head 3 into the furnace chamber 11 and aims it at the position on the top of the furnace chamber 11 that needs to be cleaned. First, acid cleaning fluid is sprayed to soften and loosen the scabs, and then the scabs are rinsed with high-pressure water. After cleaning is completed, the adjustment mechanism recovers the cleaning head 3 back into the cleaning chamber 21. The above structure has the following advantages: ① Automatic cleaning replaces manual cleaning, enabling accurate and comprehensive cleaning of hard-to-clean areas (top of furnace 11), improving cleaning efficiency and effectiveness; ② Real-time transmission of close-up images by camera 31 makes remote operation more reliable; ③ The cleaning method using acidic cleaning solution (which can be low-solubility hydrochloric acid) combined with high-pressure water reduces the amount of acidic cleaning solution used, thereby reducing the possibility of damage to furnace 11. Furthermore, high-pressure water can more easily remove scabs, reducing water consumption and saving water resources; ④ The addition of a gate mechanism protects the cleaning device, extends its service life, and prevents heat and flue gas leakage used for power generation from causing environmental pollution.

[0025] The adjustment mechanism includes a main turntable 4 rotatably mounted on the top of the cleaning chamber 21. A circumferential motor 41 driving the main turntable 4 to rotate is mounted above the cleaning chamber cover 2. Below the main turntable 4 are a swing arm seat 42, a main swing arm 43 hinged to the swing arm seat 42, and a main swing motor 44 driving the main swing arm 43 to swing up and down. Below the swing end of the main swing arm 43 are multiple secondary swing arms 45 that are hinged end to end. To increase the range of motion, four secondary swing arms 45 are preferred in the specific embodiment. The swing end of the main swing arm 43 is provided with an auxiliary swing motor driving the uppermost secondary swing arm 45 to swing up and down. The machine 46 has a secondary swing motor 47 located at the lower end of the upper secondary swing arm 45 between adjacent secondary swing arms 45, which drives the lower secondary swing arm 45 to swing up and down. The lower end of the lowest secondary swing arm 45 has a directional motor 48 that drives the cleaning head 3 to rotate. The horizontal rotation of the turntable, the up and down swing of the main swing arm 43, the up and down swing of the multiple secondary swing arms 45, and the rotation of the cleaning head 3 enable precise and rapid large-range and multi-directional posture adjustment of the cleaning head 3, thereby meeting the cleaning needs of each surface and corner of the furnace 11 top and further ensuring the cleaning effect.

[0026] Roller seats 5 are respectively provided on both sides of the upper part of the cleaning chamber cover 2. The roller seats 5 are rotatably equipped with a pipe take-up roller 51 and a roller motor 52 that drives the pipe take-up roller 51 to rotate. One pipe take-up roller 51 is used to take up and put down the water supply hose 53 connecting the water source and the high-pressure water nozzle 32. The other pipe take-up roller 51 is used to take up and put down the cleaning fluid hose 54 connecting the acidic cleaning fluid source and the cleaning fluid nozzle 33.
