[0024] 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.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A boiler cleaning structure includes a biomass boiler body 1, a wall scraping structure 2 bolted to the inner side of the biomass boiler body 1, and a collection structure 3 inserted into the inner side of the biomass boiler body 1.
[0027] The wall scraping structure 2 includes an electric push rod 21, a fixing frame 22, a connecting block 23, and a cleaning frame 24. The bottom of the electric push rod 21 is bolted to the top of the biomass boiler body 1, and the output end of the electric push rod 21 is slidably connected to the inner wall of the biomass boiler body 1. The bottom of the electric push rod 21 is bolted to the top of the fixing frame 22. The outer side of the fixing frame 22 is fixedly connected to the inner side of the connecting block 23. The inner side of the connecting block 23 is bolted to the outer side of the cleaning frame 24. The outer side of the cleaning frame 24 is movably connected to the inner side of the biomass boiler body 1.
[0028] In this embodiment: By setting up the biomass boiler body 1, an installation foundation is provided for the wall scraping structure 2 and the collection structure 3. The wall scraping structure 2 is provided in which the electric push rod 21 is bolted to the top of the biomass boiler body 1 at its bottom, serving as the power source for the wall scraping structure 2. Through telescopic movement, it drives the fixing frame 22, the connecting block 23 and the cleaning frame 24 to move up and down, thereby achieving comprehensive cleaning of the inner wall of the boiler. The fixing frame 22 transmits the power of the electric push rod 21 to the connecting block 23 and the cleaning frame 24. The connecting block 23 firmly connects the fixing frame 22 and the cleaning frame 24 together, so that the power transmitted by the fixing frame 22 can effectively drive the cleaning frame 24 to move. The cleaning frame 24 directly contacts the inner wall of the boiler and can scrape off dirt, ash and other impurities attached to the inner wall of the boiler.
[0029] Specifically, such as Figure 3 , Figure 4As shown, the collection structure 3 includes a collection box 31, the outer side of which is inserted into the inner side of the biomass boiler body 1.
[0030] Specifically, such as Figure 3 , Figure 4 As shown, a fixing handle 32 is fixedly connected to the left side of the collection box 31. There are two fixing handles 32, which are respectively set on both sides of the left side of the collection box 31.
[0031] Specifically, such as Figure 3 , Figure 4 As shown, a movable plate 33 is slidably connected to the inner side of the collection box 31, and a connector 34 is bolted to the left side of the movable plate 33. The outer wall of the connector 34 is slidably connected to the inner wall of the collection box 31.
[0032] In this embodiment: a collection structure 3 is provided, wherein the collection box 31 is used to collect the dirt and impurities cleaned by the wall scraping structure 2, and the fixed handle 32 is provided for the operator to apply force, making it easy to grip and apply force when installing and disassembling the collection box 31. The movable plate 33 can move back and forth in the collection box 31 through the connector 34. Pulling the movable plate 33 can scrape the inner side of the collection box 31. The connector 34 connects the movable plate 33 to the collection box 31, so that the movable plate 33 can slide smoothly in the collection box 31.
[0033] Specifically, such as Figure 3 As shown, a mounting hole 4 is provided on the left side of the collection box 31, and the connector 34 passes through the mounting hole 4 and is connected to the movable plate 33.
[0034] Specifically, such as Figure 4 As shown, a connection hole 5 is provided on the top of the biomass boiler body 1, and an electric push rod 21 passes through the connection hole 5 and is connected to the top of the fixed frame 22.
[0035] In this embodiment: the mounting hole 4 opened in the collection box 31 allows the connector 34 to pass through the collection shell and connect to the movable plate 33. By pulling the connector 34 to slide on the inner wall of the collection box 31, the movable plate 33 can be moved inside the collection box 31. The connecting hole 5 opened in the biomass boiler body 1 facilitates the through-installation of the electric push rod 21 to realize the lifting function of the scraping structure 2.
[0036] Specifically, such as Figure 2 As shown, a fixing block 6 is fixedly connected to the top of the cleaning frame 24, and the outer side of the fixing block 6 is bolted to the inner side of the connecting block 23.
[0037] Specifically, such as Figure 1 , Figure 5 As shown, the bottom of the biomass boiler body 1 is fixedly connected with four support columns 7, which are respectively set at the bottom of the biomass boiler body 1.
[0038] In this embodiment: the fixing block 6 fixed to the top of the cleaning frame 24 is used to fix the frame 22 to the cleaning frame 24. By setting four support columns 7 evenly distributed, the stability of the biomass boiler body 1 is improved.
[0039] Working principle: When the boiler cleaning structure is working, the electric push rod 21 first serves as the power source for the wall scraping structure 2. Its bottom is bolted to the top of the biomass boiler body 1, and its output end passes through the connecting hole 5 to drive the fixing frame 22, connecting block 23, and cleaning frame 24 to slide along the inner side of the biomass boiler body 1. The cleaning frame 24 directly contacts the inner wall of the boiler. Under the extension and retraction of the electric push rod 21, it moves up and down to scrape off the dirt, ash, and other impurities attached to the inner side of the biomass boiler body 1. The dirt and impurities scraped off by the cleaning frame 24 will fall off. At this time, the collection structure 3 plays a role. The collection box 31 is inserted into the inner side of the biomass boiler body 1 to receive the scraped impurities. The operator can easily install or remove the collection box 31 through the fixing handle 32. When there are many impurities in the collection box 31, the connecting piece 34 is pulled. Since the connecting piece 34 passes through the mounting hole 4 and is connected to the moving plate 33, it can drive the moving plate 33 to slide in the collection box 31 to scrape the inner side of the collection box 31, scraping off the impurities attached to the box wall for easy centralized cleaning.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
