[0036] 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.

[0037] 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. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] In the related art, the top cover of a small diameter reactor usually adopts a flat cover structure, which can ensure that the mechanical stirring structure does not produce a large displacement during operation. However, the surface area of ​​the flat cover is relatively small, and when installing the spray device, the flat cover of the top cover is not enough to accommodate more nozzles, which limits the functionality and expandability of the reactor.

[0039] 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.

[0040] The present application provides some embodiments of the side wall spray device. Figure 1 , Figure 2 As shown, the side wall spray device 1 includes a mounting seat 2 and a spray assembly 3. The mounting seat 2 is arranged on the side wall of the tank body 10. The mounting seat 2 includes a mounting hole 20, and the mounting hole 20 can connect the inside and the outside of the tank body 10. The spray assembly 3 is connected to the mounting seat 2 through the mounting hole 20. The spray assembly 3 is partially located inside the tank body 10 and partially located outside the tank body 10. The cleaning liquid can be introduced from the outside of the tank body 10 into the inside of the tank body 10, so as to clean the tank body 10.

[0041] Specifically, the spray assembly 3 is installed on the mounting seat 2 on the side wall of the tank body 10. When cleaning the equipment, the inner end of the spray assembly 3 can spray the cleaning liquid onto the back of the stirring blade to clean the back to meet the cleanliness requirements of biomedical sanitary-grade reaction equipment.

[0042] The cleaning liquid may be water, or an alkaline liquid or an acidic liquid may be selected according to the acid-base environment inside the stirring device, and is not specifically limited.

[0043] The side wall spray device 1 provided in the present application, by setting a mounting seat 2 on the side wall of the tank body 10 and installing the spray assembly 3 on the mounting seat 2, sprays cleaning liquid from the side wall of the tank body to the interior of the equipment, which can cover a larger area, expand the cleaning range, and improve the cleaning effect.

[0044] At the same time, compared with the side wall spray device 1 installed on the top head of the tank body, the side wall spray device 1 is installed on the side wall of the tank body, which can accommodate more cleaning pipes and enhance the functionality and expandability of the reactor.

[0045] Reference Figure 2 , Figure 3 As shown, in one embodiment, the spray assembly 3 includes a cleaning pipe 31 and a spray head 32, the spray head 32 is connected to the cleaning pipe 31, the spray head 32 includes a spray chamber 320 and a spray hole 321, and the spray hole 321 is connected to the spray chamber 320. The cleaning pipe 31 includes a cleaning channel 30, one end of the cleaning channel 30 is provided with a water inlet 301, and the other end is provided with a water outlet 302, and the water outlet 302 is connected to the spray chamber 320.

[0046] It should be noted that the cleaning pipe 31 can be a continuous pipe or a component formed by connecting multiple pipe sections. These pipe sections can be of the same material and diameter, or they can be different according to different application requirements. The connection methods include but are not limited to threaded connection, welding, snap connection, etc.

[0047] Part of the cleaning pipe 31 and the spray head 32 are located inside the tank body 10 , which can reduce the cleaning distance between the spray head 32 and the stirring mechanism 11 , and clean the blades of the stirring mechanism 11 more specifically.

[0048] In other embodiments, the spray assembly 3 may also adopt a cleaning valve or the like installed on the side wall of the tank.

[0049] Reference Figure 2 , Figure 3 As shown, in one embodiment, the spray head 32 includes a spherical shell, and a plurality of spray holes 321 arranged evenly are provided on the shell, and a spray chamber 320 is formed in the shell.

[0050] The sphere in this embodiment includes a spherical shape and a curved geometric body similar to a spherical shape with a certain curvature. For example, the shell shape of the shower head 32 can be a sphere, an ellipsoid or a lantern.

[0051] Among them, a spherical spray head 32 is used, and its structural shape is convenient for setting spray holes for multi-angle spraying, which can increase the spray coverage area and improve the cleaning range. In addition, through multiple evenly arranged spray holes 321, the cleaning liquid is more evenly distributed in the sprayed area, ensuring that all parts can be cleaned or treated more uniformly. At the same time, the inner wall of the spherical shell has a smooth transition, and it is not easy for liquid to accumulate in the spray chamber 320.

[0052] In one embodiment, the mounting hole 20 includes a flared structure 201 , and a cross-sectional area of ​​an end of the flared structure 201 close to the sprinkler head 32 is larger than a cross-sectional area of ​​an end of the flared structure 201 close to the water inlet 301 .

[0053] Specifically, the expansion structure of the mounting hole 20 is a conical or trumpet-shaped hole with one end larger than the other end. On the one hand, the inclination angle of the cleaning pipe 31 when it is installed in the mounting hole 20 can be adjusted, thereby adjusting the cleaning range. On the other hand, since the spray range of the spherical spray head 32 is relatively wide, part of the cleaning liquid may flow into the mounting hole 20. The expansion structure 201 helps the cleaning liquid in the mounting hole 20 to flow to the bottom of the equipment along the inclined hole wall, which is convenient for drainage and prevents liquid accumulation. This can prevent the liquid residue from corroding or contaminating the equipment and improve the overall sanitation of the equipment.

[0054] Reference Figure 2 , Figure 3As shown, in one embodiment, the cleaning channel 30 includes a fractal flow channel, and the number of water outlets 302 is greater than the number of water inlets 301, wherein the fractal flow channel can be a two-forked flow channel divided into two, or a three-forked flow channel divided into three, or a four-forked flow channel divided into four, etc. In addition, the fractal flow channel can also be a two-stage forked flow channel, for example, one is divided into two, and two are divided into four. Of course, the fractal flow channel can also adopt an irregular forking method, for example, the forked flow channels are asymmetric or uneven.

[0055] Specifically, the spray assembly 3 includes at least two spray heads 32, the cleaning pipe 31 includes a connecting pipe 311 and at least two branch pipes 312, the water inlet 301 is arranged on the connecting pipe 311, and the branch pipe 312 is connected between the spray head 32 and the connecting pipe 311 to form a fractal flow channel.

[0056] In some embodiments, the shower heads 32 are connected to the branch pipes 312 in a one-to-one correspondence, that is, one shower head 32 is connected to one branch pipe 312 .

[0057] In some embodiments, a plurality of shower heads 32 are connected to the same branch pipe 312 .

[0058] The spray heads 32 and the branch pipes 312 are connected one-to-one or many-to-one. Alternatively, some of the spray heads 32 are connected one-to-one with the branch pipes 312, while some of the spray heads 32 are connected many-to-one with the branch pipes 312. That is, each spray head 32 can be controlled by an independent pipeline, or multiple spray heads 32 can be controlled simultaneously by a common pipeline. Specifically, the arrangement of the spray heads can be flexibly set according to needs.

[0059] Further, refer to Figure 2 , Figure 3 As shown, in some embodiments, at least two spray heads 32 are arranged in a bifurcated manner in a horizontal plane. The bifurcated arrangement refers to a spray head 32 with multiple branches distributed in different directions from the connecting pipe 311, corresponding to the above-mentioned fractal flow channel.

[0060] In some embodiments, at least two shower heads 32 are arranged in a vertical plane.

[0061] In some embodiments, a portion of the spray heads 32 are arranged in a horizontal plane, and another portion of the spray heads 32 are arranged in a vertical plane. This arrangement can enrich the spray angles of the spray assembly 3 .

[0062] The cleaning channel 30 extends from the inside of the connecting pipe 311 to the inside of each branch pipe 312, and then the cleaning channel 30 is connected to the spray chamber 320 of the spray head 32 through the water outlet 302. By setting a plurality of bifurcated branch pipes 312, the spray range and coverage area of ​​the side wall spray device can be greatly increased, and the cleaning efficiency can be improved. In addition, the bifurcated branch pipes 312 are distributed around the mounting hole 20, which also reduces the risk of liquid leakage from the mounting hole 20 to the outside to a certain extent.

[0063] Optionally, an obtuse angle is formed between the central axis of the connecting pipe 311 and the plane where each branch pipe 312 is located.

[0064] Further, refer to Figure 2 , Figure 3 As shown, in one embodiment, the spray assembly 3 includes two spray heads 32 , each spray head 32 is connected to a branch pipe 312 , the branch pipe 312 is a curved pipe, and the two branch pipes 312 are symmetrically arranged on both sides of the connecting pipe 311 .

[0065] Among them, the branch pipe 312 is a curved pipe, and the outline of the branch pipe 312 can be an arc or other curved shape. The two branch pipes 312 on both sides of the connecting pipe 311 can form a 180-degree semi-circular curved pipe. Exemplarily, when cleaning the equipment, the tank body 10 is arranged vertically, and the two branch pipes 312 can be located on the same horizontal plane, and then the spray head 32 at the end of the branch pipe 312 can spray the cleaning liquid from the left and right sides of the stirring mechanism toward the periphery of the spray head 32. Among them, through the fractal flow channel and multiple spray heads in the spray assembly 3, an all-round and efficient cleaning effect can be achieved, the cleaning quality can be effectively improved, while reducing the waste of cleaning liquid, ensuring the uniformity and consistency of the cleaning process.

[0066] Reference Figure 3 , Figure 4 As shown, in one embodiment, the side wall spray device 1 includes a support member 6 for supporting the branch pipe 312 , and the support member 6 is used to be connected to the inner wall of the tank body 10 .

[0067] Specifically, a support member 6 is cantilevered and fixed on the inner wall of the tank body 10. The support member 6 is a rod and can be made of round steel. The support member 6 supports the branch pipe 312 upward and can correspond to the branch pipe 312 one by one. The length extension direction of the support member 6 can be located in the radial direction of the tank body 10.

[0068] Reference Figure 2 , Figure 5As shown, in one embodiment, the connecting pipe 311 includes a first pipe section 3111, a first transition pipe 3112, and a second pipe section 3113 connected in sequence, and the water inlet 301 is arranged at the first pipe section 3111. The first transition pipe 3112 includes a first tapered hole, and the cross-sectional area of ​​the end of the first tapered hole close to the first pipe section 3111 is larger than the cross-sectional area of ​​the end of the first tapered hole close to the second pipe section 3113. The branch pipe 312 includes a third pipe section 3121, a second transition pipe 3122, and a fourth pipe section 3123 connected in sequence, and the water outlet 302 is arranged at the fourth pipe section 3123. The second transition pipe 3122 includes a second tapered hole, and the cross-sectional area of ​​the end of the second tapered hole close to the third pipe section 3121 is larger than the cross-sectional area of ​​the end of the second tapered hole close to the fourth pipe section 3123. The second pipe section 3113 is connected to the third pipe section 3121.

[0069] Specifically, the cross section of the cleaning channel 30 is a circular hole. The first pipe section 3111, the first transition pipe 3112 and the second pipe section 3113 are coaxially arranged, the third pipe section 3121, the second transition pipe 3122 and the fourth pipe section 3123 are coaxially arranged, the inner diameter of the first pipe section 3111 is larger than the aperture of the second pipe section 3113, the inner diameter of the second pipe section 3113 is the same as the inner diameter of the third pipe section 3121, and the inner diameter of the fourth pipe section 3123 is smaller than the inner diameter of the third pipe section 3121. The first transition pipe 3112 and the second transition pipe 3122 both use concentric reducers.

[0070] Among them, a conical hole is set at the position of the connecting pipe 311 near the water inlet 301, and when connected to the cleaning liquid source, the flow rate of the cleaning liquid entering the cleaning pipe can be controlled. In addition, a conical hole is set at the branch pipe 312 connecting the spray head, and the flow rate of the cleaning liquid entering the spray head can be accurately adjusted to match the designed flow rate of the spray head. The size and shape of the conical hole can change the flow rate and flow rate of the liquid, ensuring that the spray head can work normally and achieve the expected cleaning effect.

[0071] Reference Figure 2 , Figure 7 As shown, in one embodiment, the side wall spray device 1 includes a clamping nut 4 and a limiting ring 5, the mounting seat 2 includes an external threaded portion 21, the external threaded portion 21 is arranged on the outer peripheral surface of the mounting seat 2, the clamping nut 4 includes a threaded hole 41 and a clamping head 42 arranged at one end of the threaded hole 41, and the threaded hole 41 is threadedly matched with the external threaded portion 21. The cleaning pipe 31 passes through the clamping nut 4, and a limiting groove 40 is formed between the clamping head 42 and the end of the mounting seat 2. The limiting ring 5 is arranged on the outer periphery of the cleaning pipe 31 to form a shoulder structure. The clamping nut 4 presses the limiting ring 5 against the limiting groove 40 along the axial direction of the mounting hole 20.

[0072] Specifically, the mounting seat 2 includes a flange plug with external threads, and the compression nut 4 is a plug nut, which is screwed together with the flange plug to press and fix the limiting ring 5 on the cleaning pipe 31 in the limiting groove 40. The limiting ring 5 is fixed to the outer periphery of the cleaning pipe 31 to form a shoulder structure, and the limiting ring 5 and the cleaning pipe 31 can be integrally arranged or separately fixedly connected.

[0073] The threaded connection between the clamping nut 4 and the mounting seat 2 facilitates installation and removal. At the same time, the clamping nut 4 can also block the opening of one end of the mounting hole 20 to prevent fluid leakage. That is, the clamping nut 4 also serves as an end cover, simplifies the structure, and improves the convenience of installation.

[0074] Reference Figure 2 , Figure 5 , Figure 6 As shown, in one embodiment, the cleaning pipe 31 includes a flat joint 313, which is installed in the mounting hole 20. The outer periphery of the flat joint 313 is provided with a first slot 3131, a second slot 3132 and a third slot 3133 arranged at intervals. A spring retaining ring is installed in the first slot 3131, and the spring retaining ring is located on the side of the clamping nut 4 away from the mounting seat 2. A limiting ring 5 is installed in the second slot 3132. A sealing ring is installed in the third slot 3133, and the sealing ring is located in the mounting hole 20 and sealed between the flat joint 313 and the mounting hole 20. The spring retaining ring is stopped on the side of the clamping nut 4 away from the mounting seat 2, and is used to limit the axial movement of the clamping nut 4, prevent the nut from loosening and causing leakage, and improve the reliability and safety of the connection. A sealing ring is installed between the outer peripheral surface of the flat joint 313 and the mounting hole 20 to ensure the sealing inside the equipment.

[0075] Specifically, the cleaning pipe 31 includes a flat joint 313, and the flat joint 313 may include a first pipe section 3111 and a first transition pipe 3112. The water inlet 301 is located at the end of the flat joint 313, and the cleaning pipe 31 is connected to the external pipeline through the flat joint connection part to introduce the cleaning liquid in the external pipeline into the cleaning channel 30. The spray head 32 is connected to the water outlet 302 of the cleaning pipe 31 through a pin shaft, and the cleaning liquid enters the spray chamber 320 from the cleaning channel 30, and then sprays into the tank body from the spray hole 321. Among them, the second pipe section 3113 is a sanitary pipe, and the flat joint 313 is connected to each branch pipe 312 of the fork through the sanitary pipe. The flat joint 313 is connected to the second pipe section 3113 to form a connecting pipe 311.

[0076] Optionally, the connecting pipe 311 is obliquely arranged on the side wall of the tank body 10 so that the second pipe section 3113 is lower than the first pipe section 3111 .

[0077] Furthermore, the cleaning pipe 31 can be an on-site cleaning pipeline, which can realize efficient and automatic cleaning of production equipment and pipelines without disassembling the equipment, which is beneficial to improving production efficiency and reducing manual operations and equipment downtime.

[0078] Reference Figure 1 As shown, another embodiment of the present application provides a stirring device, the stirring device 100 includes a tank body 10 and a stirring mechanism 11, and the stirring mechanism 11 is arranged in the tank body 10. The stirring device 100 also includes the side wall spray device in the above embodiment, and the side wall spray device is installed on the tank body 10.

[0079] The stirring device 100 provided in the present application, by setting a mounting seat 2 on the side wall of the tank body 10 and installing the spray assembly 3 on the mounting seat 2, sprays cleaning liquid from the side wall of the tank body to the interior of the device, which can cover a larger area, expand the cleaning range, and improve the cleaning effect.

[0080] Furthermore, the design of multiple spray heads further expands the cleaning range. For example, when the spray assembly includes at least two spray heads, and the branch pipes correspond to the spray heads one by one, the multiple spray heads can clean the inside of the tank from different angles, increasing the area covered by the cleaning liquid.

[0081] Furthermore, the spray head adopts a spherical shell and is provided with multiple spray holes arranged evenly, so that the cleaning liquid is distributed more evenly in the sprayed area. This uniform distribution ensures that all parts inside the tank can be cleaned or treated more uniformly, improving the quality and effect of cleaning.
