[0045] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0046] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

[0047] The scraping wall stirring equipment is an important device widely used in industrial production and experimental research. Its main feature is that while the stirring mechanism is stirring, it can be in close contact with the inner wall of the tank through the scraping mechanism to effectively scrape off the materials attached to the wall. Among them, the scraping mechanism is a special scraper or scraper structure.

[0048] Scraped wall mixing equipment has a lot of functions. First, it can ensure that the materials are fully mixed during the mixing process, avoiding stratification or unevenness. For example, in the food processing industry, when making thick sauces, scraped wall mixing can ensure that the various ingredients are evenly distributed.

[0049] Secondly, scraping the material off the wall can prevent the material from agglomerating, burning or deteriorating on the wall. This is particularly important in chemical production. For example, some chemical reactions require strict temperature control. If the material accumulates on the wall, it may cause local overheating.

[0050] Currently, for scraping wall stirring equipment, using a spray device to spray cleaning liquid inside is a relatively common cleaning method. However, due to the complex structure of the scraping wall stirring mechanism, the current spray device has many spray dead angles, resulting in poor cleaning effect.

[0051] Based on this, the present application provides a side wall spray device to solve the above technical problems, with specific reference to the following embodiments.

[0052] Reference Figure 1-3 As shown, an embodiment of the present application discloses a side wall spray device, which includes a mounting seat 1 and a spray assembly 2, wherein the mounting seat 1 is used to be installed on a tank body 200 to be cleaned, and the tank body 200 to be cleaned includes a scraping wall surface 210 in contact with a scraping mechanism; the spray assembly 2 is connected to the mounting seat 1, and the spray assembly 2 is used to spray cleaning liquid from an opening arranged on the scraping wall surface 210 to a target position in the tank body 200 to be cleaned; wherein the working space of the scraping mechanism does not overlap with the spray assembly 2.

[0053] The cleaning liquid may be pure water, or an alkaline liquid or an acidic liquid may be selected according to the acid-base environment inside the mechanical stirring equipment, and is not specifically limited.

[0054] The side wall spray device 100 provided in this embodiment can spray the cleaning liquid from the openings arranged on the scraping surface 210 to the target position in the tank body 200 to be cleaned by setting the spray component 2, and can perform close-range and multi-angle cleaning on the stirring mechanism 220 and the scraping mechanism in the tank body 200 to be cleaned, thereby reducing cleaning dead corners and having the advantages of good cleaning effect and high cleaning efficiency.

[0055] At the same time, the working space of the scraping mechanism does not overlap with the spray assembly 2, which can prevent the setting of the spray assembly 2 from affecting the normal operation of the scraping mechanism, and can be cleaned when the stirring mechanism 220 and the scraping mechanism are in motion, further improving the cleaning effect. The scraping mechanism is usually connected to the stirring mechanism 220 and driven by the same driving source. Therefore, when the stirring mechanism 220 is in motion, the scraping mechanism is also in motion at the same time.

[0056] Specifically, the scraping mechanism and the scraping surface 210 are as close as possible, and the working space of the scraping mechanism can be understood as the space surrounded by the scraping surface 210. The working space of the scraping mechanism does not overlap with the spray assembly 2, which can be understood as the spray assembly 2 being recessed outward on the scraping surface 210 so that the spray assembly 2 is located outside the space surrounded by the scraping surface 210. Exemplarily, the space surrounded by the scraping surface 210 is cylindrical, and the spray assembly 2 is located outside the cylindrical space, and a gap is left between the spray assembly 2 and the boundary of the cylindrical space to ensure that the spray assembly 2 and the scraping mechanism can work simultaneously without interfering with each other.

[0057] The spray assembly 2 and the mounting base 1 can be an integrated structure or a split structure, which is not specifically limited. When the spray assembly 2 and the mounting base 1 are an integrated structure, the spray assembly 2 and the mounting base 1 are connected to the tank body 200 to be cleaned as a whole by welding or bolting.

[0058] During installation, a hole can be first opened on the scraping wall surface 210 of the tank body 200 to be cleaned, and then the mounting base 1 is installed on the tank body 200 to be cleaned, and the spray component 2 is installed on the mounting base 1, so that the cleaning liquid sprayed by the spray component 2 can be sprayed from the hole on the scraping wall surface 210 to the target position inside the tank body 200 to be cleaned.

[0059] Reference Figure 3 As shown, a plurality of spray assemblies 2 may be provided, and the plurality of spray assemblies 2 are distributed at different positions of the scraping wall surface 210 , so as to achieve cleaning of different positions in the tank body 200 to be cleaned.

[0060] In one embodiment, the mounting seat 1 is welded to the tank body 200 to be cleaned, and the working space of the scraping mechanism does not overlap with the mounting seat 1. The mounting seat 1 is welded to the tank body 200 to be cleaned to ensure the stability of the structure, and the working space of the scraping mechanism does not overlap with the mounting seat 1, which can prevent the setting of the mounting seat 1 from affecting the normal operation of the scraping mechanism. Optionally, a receiving cavity 11 is provided in the mounting seat 1, and the spray assembly 2 is at least partially located in the receiving cavity 11.

[0061] Reference Figures 4 to 6 As shown, in one embodiment, the spray assembly 2 includes a spray plate 21 , and a spray opening 211 is provided on the spray plate 21 , and the cleaning liquid can be sprayed to the target position in the tank body 200 to be cleaned through the spray opening 211 .

[0062] In one embodiment, a plurality of spray openings 211 are provided, and the plurality of spray openings 211 are used to spray the cleaning liquid to a plurality of target positions in the tank body 200 to be cleaned, so that a single spray piece 21 can clean a plurality of target positions in the tank body 200 to be cleaned at the same time. Furthermore, the plurality of spray pieces 21 distributed at different positions of the scraping wall surface 210 can clean different positions in the tank body 200 to be cleaned, and clean the same position from different angles, thereby improving the cleaning effect. Figure 3 shown.

[0063] Please continue to refer to Figure 5As shown, in one embodiment, a plurality of spray openings 211 are arranged in an array on the spray sheet 21. Specifically, the plurality of spray openings 211 may be arranged in a horizontal direction (such as the X direction in the figure) and in a vertical direction (such as the Y direction in the figure). Optionally, the plurality of spray openings 211 have the same size. In another embodiment, the spray openings 211 have different sizes, and spray openings 211 of different sizes can be used to clean different target locations.

[0064] Furthermore, when a target position is difficult to clean, multiple spray openings 211 or larger spray openings 211 may be provided for the target position to improve the cleaning effect. When a target position is easy to clean, fewer spray openings 211 or smaller spray openings 211 may be provided for the target position.

[0065] Optionally, the spray opening 211 is oval, circular, rectangular, etc., without specific limitation.

[0066] Please continue to refer to Figure 4 As shown, in one embodiment, the spray sheet 21 includes an arc-shaped portion 212, and a plurality of spray openings 211 are distributed at different positions on the arc-shaped portion 212. By providing the spray openings 211 at different positions on the arc-shaped portion 212, the cleaning liquid can be sprayed out at different angles to form a larger cleaning width, thereby achieving the cleaning of a large target area of ​​the tank body 200 to be cleaned, so that a small number of spray sheets 21 can cover the entire area of ​​the tank body 200 to be cleaned. Further, the spray sheet 21 also includes a mounting portion 214, wherein the mounting portion 214 is arranged around the arc-shaped portion 212. The mounting portion 214 is arranged between the mounting seat 1 and the valve assembly 3, and is used to fix the spray sheet 21.

[0067] Furthermore, the spray assembly 2 includes multiple types of spray pieces 21, and the curvature of the arc-shaped portion 212 corresponding to different types of spray pieces 21 is different, so that different types of spray pieces 21 have different cleaning widths. Among them, the larger the curvature of the arc-shaped portion 212, the larger the cleaning width of the spray piece 21, and the more conducive to cleaning the scraping mechanism. Therefore, different types of spray pieces 21 can be applied to different tanks 200 to be cleaned, or suitable for being installed at different positions on the scraping surface 210 of the tank 200 to be cleaned.

[0068] Specifically, Figure 7 The arc of the arc portion 212 of the middle spray plate 21 is greater than Figure 4 The curvature of the arc-shaped portion 212 of the middle spray plate 21 is, therefore, Figure 7 The cleaning width of the middle spray piece 21 is greater than Figure 4 The cleaning width of the spray plate 21. For example, refer to Figure 6 and 8As shown, the cleaning widths of the spray plates 21 are 138 degrees and 114 degrees respectively.

[0069] Optionally, the inner and outer sides of the arc portion 212 may be spherical. In order to achieve different cleaning effects, spray pieces 21 with different curvatures may be selected for different scraping and stirring devices, or spray pieces 21 with different curvatures may be arranged at different positions of the same scraping and stirring device.

[0070] Please continue to refer to Figure 6 and 8 As shown, in some embodiments, an annular slope 13 is provided on the mounting seat 1, and the annular slope 13 forms a trumpet-shaped space on one side of the spray opening 211 of the spray plate 21, so as to prevent the mounting seat 1 from blocking the spray path of the cleaning liquid, which is beneficial to increase the breadth of cleaning.

[0071] Please continue to refer to Figure 5 As shown, in one embodiment, the spray plate 21 is further provided with a drain opening 213. After the spray plate 21 is connected to the mounting seat 1, the drain opening 213 is located below the spray opening 211. When the wall scraping and stirring device is working, the material in the tank may enter the spray opening 211. The drain opening 213 can discharge the material during spraying, and drain the cleaning liquid after spraying to avoid residual cleaning liquid. At the same time, the drain opening 213 can play a role in assisting alignment during installation.

[0072] In one embodiment, the number of the drain openings 213 is two. After the spray plate 21 is connected to the mounting base 1, the two drain openings 213 are respectively located above and below the spray opening 211. The two drain openings 213 can be better aligned during installation. Optionally, the drain opening 213 is elliptical, circular, rectangular, etc., which is not specifically limited.

[0074] Specifically, the valve head 32 controls the valve weir 34 by adjusting the position of the diaphragm to open or close the flow channel 33. After the flow channel 33 is opened, the cleaning liquid enters the spray chamber 35 through the liquid outlet 332. The spray chamber 35 plays a role of temporarily storing water and distributes the cleaning liquid to different spray openings 211, ensuring that the cleaning liquid in the spray chamber 35 is sprayed to different positions in the tank body 200 to be cleaned through different spray openings 211.

[0075] Reference Fig. 9 As shown, in one embodiment, the flow channel 33 includes a first section 333 and a second section 334, forming a structure that is wide at the top and narrow at the bottom, and the valve weir 34 is arranged between the first section 333 and the second section 334. Further, the first section 333 forms a structure that is large at the top and small at the bottom, which is convenient for increasing the flow rate of the cleaning liquid after the cleaning liquid enters the flow channel 33, so as to increase the pressure in the spray chamber 35, thereby increasing the initial velocity of the spray liquid ejected outward from the spray opening 211. Further, the second section 334 is arranged obliquely, and the size and shape of the cross section of the second section 334 along the direction perpendicular to its extension remain unchanged, so as to facilitate the cleaning liquid to quickly enter the spray chamber 35.

[0076] In one embodiment, the side wall spray device 100 further includes a fastener 4, and the valve seat 31 is detachably connected to the mounting seat 1 through the fastener 4, so as to facilitate the disassembly and assembly of the valve seat 31. The fastener 4 can be a screw, a bolt, etc. When the spray plate 21 needs to be replaced, the valve seat 31 can be removed and replaced.

[0077] Optionally, there are multiple fasteners 4, which are arranged in a ring shape on the valve seat 31, and are respectively used to connect the valve seat 31 with different positions on the mounting seat 1 to increase structural stability. Furthermore, the fasteners 4 are arranged away from the flow channel 33 to avoid affecting the flow of the cleaning liquid in the flow channel 33.

[0078] Optionally, during installation, the spray sheet 21 is clamped between the mounting seat 1 and the valve seat 31. After the fastener 4 connects the valve seat 31 to the mounting seat 1, the spray sheet 21 is also fixed between the mounting seat 1 and the valve seat 31. Figure 2 As shown, a slot 12 is provided on the mounting seat 1, and the spray plate 21 is stuck in the slot 12, and then the valve seat 31 is connected to the mounting seat 1 by a fastener 4.

[0079] Please refer to Figure 1 and 8As shown, in one embodiment, a gasket 6 is further provided between the spray piece 21 and the mounting seat 1, and between the spray piece 21 and the valve seat 31 to ensure sealing, prevent leakage of the cleaning liquid, and ensure the stability of the connection.
