Description

Technical Field

[0001] The utility model belongs to the technical field of boiler scale treatment, and particularly relates to an industrial boiler scale treatment device. Background Technique

[0002] The harms of boiler scale mainly include reducing thermal efficiency, affecting safe operation, shortening the boiler life, and economic waste. Since the thermal conductivity of the scale is much lower than that of steel, the heat transfer is blocked, resulting in increased fuel consumption and reduced thermal efficiency of the boiler. It is estimated that for every 1 mm increase in the thickness of the boiler scale, the fuel consumption increases by about 10%; at the same time, the presence of the scale causes the temperature of the boiler heating surface to rise, which may lead to metal overheating, creep, bulging, or even explosion. In addition, the scale may also cause the metal wall temperature to rise sharply, exceeding the temperature that the metal can withstand, thus triggering safety accidents.

[0003] The invention with the publication number of "CN108397910A" and the name of "A Scale Collection and Treatment Device for Small Boilers" discloses a scale treatment device for boilers. When the boiler water flows into the device, the scale in the water is intercepted in the scale collection section. After stopping the water supply, opening the first solenoid valve group allows the scale to fall into the scale storage section. That is, the scale is first collected and then mixed with the scale treatment agent to achieve the effect of cleaning the scale. This scale treatment device separates the process of melting the scale with the scale treatment agent and scraping the scale from the inner wall of the boiler into two steps, resulting in a relatively low scale removal efficiency of the device.

Specific embodiment 1

[0047] Please refer to Figures 1-9, the utility model relates to a scale treatment device for industrial boilers, which includes a water storage tank 1, and a drain pipe 2 is fixed at the bottom of the water storage tank 1; several cleaning pipes 3 are fixed on the outer wall of the drain pipe 2, and a positioning plate 4 is fixed inside the cleaning pipe 3; one side of the positioning plate 4 is fixed with a telescopic rod 5, and a spring 6 is sleeved on the outer circle of the telescopic rod 5; one end of the telescopic rod 5 is fixed with a connecting plate 7, and one end of the connecting plate 7 is fixed with a cleaning brush 8; one side of the connecting plate 7 is fixed with a fixing plate 9, and a positioning groove 10 is opened on the surface of the fixing plate 9; an installation groove 11 is opened on the surface of the water storage tank 1, an installation pipe 12 is sleeved on the outer circle of the water storage tank 1, and several connecting rods 13 are fixed on the outer circle of the installation pipe 12; one end of the connecting rod 13 is fixed with a fastening plate 14; an installation plate 15 is fixed at the top of the installation pipe 12, and first threaded holes 16 are opened on the surfaces of the installation plate 15 and the installation groove 11, and bolts are threadedly connected inside the first threaded holes 16; a water outlet 17 is opened at the bottom of the drain pipe 2, a shunt pipe 18 penetrates through the water outlet 17, a sealing plate 19 is fixed at the top of the shunt pipe 18, and the sealing plate 19 matches the inner wall of the water outlet 17; several atomizing nozzles 20 are fixed at the bottom of the shunt pipe 18.

[0048] Specifically, one end of the spring 6 is fixedly connected with the positioning plate 4, and the other end of the spring 6 is fixedly connected with the connecting plate 7.

[0049] Furthermore, the positioning groove 10 is of an "L" - shaped structure, and the fastening plate 14 is of an "I" - shaped structure; the fastening plate 14 penetrates through the positioning groove 10.

[0050] The operation process of this embodiment is as follows: When this device is in use, pour the prepared scale treatment agent into the water storage tank 1, and push the water storage tank 1 into the industrial boiler. The treatment agent in the water storage tank 1 enters the shunt pipe 18 from the drain pipe 2, and then sprays out through the atomizing nozzles 20, so as to spray the scale treatment agent onto the inner wall of the industrial boiler. If it is necessary to brush the inner wall of the industrial boiler, the bolt inside the first threaded hole 16 can be turned out, and then push the installation pipe 12 downward. The installation pipe 12 drives the connecting rod 13 at one end of it to move downward. When the fastening plate 14 at one end of the connecting rod 13 moves to the bottom of the positioning groove 10, then turn the installation pipe 12 in the opening direction of the positioning groove 10. The installation pipe 12 drives the connecting rod 13 and the fastening plate 14 to fall off from the outlet of the positioning groove 10. At this time, the connecting plate 7 and the fixing plate 9 lose the limit of the fastening plate 14. Under the action of the spring 6 inside the cleaning pipe 13, the connecting plate 7 is pushed out, and at this time the cleaning brush 8 is in close contact with the inner wall of the industrial boiler. When in use, then turn on the second motor 32, and the water storage tank 1 rotates inside the industrial boiler, and the cleaning brush 8 can brush the inner wall of the water storage tank 1. This device can evenly spray the scale treatment agent on the inner wall surface of the industrial boiler, and at the same time use tools such as the cleaning brush 8 to brush the inner wall of the industrial boiler, so that the scale can fall off from the inner wall of the industrial boiler faster, thereby improving the scale treatment efficiency of this device.

[0054] Furthermore, a second motor 32 is fixed on the top of the cover plate 29, and a support rod 33 is fixed on the outside of the second motor 32.

[0055] The operation process of this embodiment is as follows: When the device is in use, when the water storage tank 1 supplies water to the shunt pipe 18, the first motor 24 can be turned on. The output shaft of the first motor 24 drives the adjustment block 25 at one end thereof to rotate. When the adjustment block 25 rotates, it drives the second transmission blocks 26 on its outer ring to rotate. The second transmission blocks 26 drive the first transmission blocks 21 to rotate through the transmission of the transmission belt 27. The first transmission blocks 21 drive the shunt pipe 18 to rotate. The shunt pipe 18 rotates in the drain pipe 2. This device can make the several atomizing nozzles 20 on the outer wall of the shunt pipe 18 rotate rapidly when spraying water, so as to make the atomizing nozzles spray the scale treatment agent more evenly on the inner wall of the industrial boiler, and improve the contact area between the scale treatment agent and the scale.
