[0047] 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.

[0048] 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.

[0049] In the related art, inside the sanitary reaction equipment with mechanical stirring, the stirring shaft is provided with blades. In order to ensure the cleanliness of the inside of the sanitary equipment, a cleaning device is provided inside the tank. The inventors have found through research that the cleaning device is generally installed on the top cover of the equipment, and sprays downward during cleaning. The cleaning liquid flows from top to bottom to the bottom of the equipment, and other parts inside the equipment are cleaned by the cleaning liquid flowing down from the top. This cleaning method can clean the upper surface of the stirring blades, but it is difficult to clean some areas on the back, which will result in poor cleaning effect. In addition, the installation structure of the cleaning device usually has multiple bolt holes on the mounting base, which are sealed with external bolts. After a period of time, the gap between the bolts and the bolt holes will be filled with dirt.

[0050] 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.

[0051] The present application provides some embodiments of the side wall spray device. Figure 1 , Figure 2 , Figure 3 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 outside of the tank body 10. When cleaning, the spray assembly 3 enters the inside of the tank body 10 from the outside of the tank body 10 through the mounting hole 20. The spray assembly 3 is arranged on the mounting seat 2, and 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.

[0052] Specifically, when cleaning the equipment, the spray assembly 3 is inserted into the interior of the tank body 10 through the mounting hole 20, and the cleaning liquid is introduced to clean the tank body 10. The spray assembly 3 can spray the cleaning liquid onto the back of the stirring blade to clean the back.

[0053] The side wall spray device 1 provided in the present application, by arranging a mounting seat 2 on the side wall of the tank body 10, and passing the spray component 3 through the mounting hole 20 on the mounting seat 2, sprays to the back side of the stirring blade in the stirring mechanism, so that the stirring mechanism and the like in the tank body 10 to be cleaned can be cleaned at a closer distance and at a larger angle, thereby reducing cleaning dead corners, expanding the cleaning range, and improving the cleaning effect, which meets the cleanliness requirements of biomedical sanitary-grade reaction equipment, etc.

[0054] In some embodiments, the spray assembly 3 is detachably connected to the mounting base 2. In this way, the spray assembly 3 is inserted into the tank body 10 only when the inside of the tank body 10 needs to be cleaned, and the spray assembly 3 can be removed from the mounting base 2 when cleaning is not required. The cleaning needs can be flexibly met, and the spray assembly 3 can be pulled out from the tank body, which can also avoid interfering with the normal work or other operations inside the tank body, and also avoid the spray assembly 3 being fixed on the tank body 10 for a long time to cause damage and other problems, thereby extending the service life of the side wall spray device.

[0055] The minimum aperture of the mounting hole 20 is larger than the maximum outer diameter or the maximum width of the spray assembly 3 , so that the spray assembly 3 can pass through the mounting hole 20 , thereby extending into the tank body 10 or being withdrawn from the tank body 10 .

[0056] 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.

[0057] Of course, in other embodiments, when the spray assembly 3 does not need to be pulled out from the tank body 10 , the spray assembly 3 can also be fixed on the mounting seat 2 .

[0058] 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 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 310, one end of the cleaning channel 310 is provided with a water inlet 301, and the other end is provided with a water outlet 302, and the cleaning channel 310 is connected to the spray chamber 320 through the water outlet 302.

[0059] 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.

[0060] Specifically, the cleaning pipe 31 passes through the mounting hole 20, and the two can be coaxially arranged. Alternatively, the central axis of the cleaning pipe 31 and the central axis of the mounting hole 20 can be arranged at an angle.

[0061] In a preferred embodiment, the central axis of the cleaning pipe 31 is inclined relative to a plane perpendicular to the central axis of the tank body 10. For example, the central axis of the tank body 10 extends in the vertical direction, and the central axis of the cleaning pipe 31 can also be inclined downward at a certain angle relative to the horizontal plane, so that the water outlet 302 is lower than the water inlet 301, so that the spray head 32 is in a suitable spraying position and spraying angle, and gravity can be used to promote the flow of the cleaning liquid.

[0062] Specifically, the central axis of the cleaning pipe 31 forms an angle with the central axis of the tank body 10, which angle can be 90 degrees, or preferably an acute angle. That is, the axial direction of the cleaning pipe 31 can be perpendicular to the axial direction of the tank body 10, or can be relatively inclined.

[0063] Specifically, the cleaning channel 310 includes a flat joint connection portion at the end, the water inlet 301 is located at the flat joint connection portion, and the cleaning pipe 31 is connected to the external pipeline through the flat joint connection portion to guide the cleaning liquid in the external pipeline into the cleaning channel 310. 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 310 and is then sprayed into the tank body from the spray hole 321.

[0064] Part of the cleaning pipe 31 and the spray head 32 extend into the interior of the tank body 10 through the mounting hole 20, which can reduce the cleaning distance between the spray head 32 and the stirring mechanism, and clean the blades of the stirring mechanism more specifically.

[0065] In other embodiments, the spray assembly 3 may also adopt a cleaning valve or the like installed on the side wall of the tank.

[0066] Reference Figure 2 , Figure 3 As shown, in one embodiment, the cleaning pipe 31 includes a first pipe section 311, a transition pipe section 312 and a second pipe section 313 connected in sequence, the water inlet 301 is located in the first pipe section 311, the water outlet 302 is located in the second pipe section 313, and the transition pipe section 312 includes a tapered hole, and the cross-sectional area of ​​the tapered hole near the end of the first pipe section 311 is larger than the cross-sectional area of ​​the end of the tapered hole near the second pipe section 313.

[0067] Specifically, the first pipe section 311 and the second pipe section 313 can adopt sanitary pipes and be coaxially arranged, and the tapered hole of the transition pipe section 312 is a concentric reducer structure. The first pipe section 311 may include a flat joint connection portion to connect to an external pipeline. The spray head 32 is connected to the second pipe section 313 through a pin shaft.

[0068] The conical transition pipe section 312 provided in the cleaning pipe 31 can adjust the water flow. For example, when the water flows through the conical hole, the hole diameter gradually decreases, and according to the principle of fluid mechanics, the water flow speed will increase. After the high-speed water flow is ejected from the water outlet 302, it has a greater impact force, thereby improving the cleaning effect on the object or area being cleaned.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Optionally, 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 .

[0073] 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.

[0074] Reference Figure 2 , Figure 4As shown, in some embodiments, the side wall spray device 1 includes a clamping structure 4 and a positioning structure 5, the clamping structure 4 is detachably mounted on the mounting seat 2, the cleaning pipe 31 in the spray assembly 3 passes through the clamping structure 4, a limiting groove 40 is formed between the clamping structure 4 and the mounting seat 2, the positioning structure 5 is arranged on the outer periphery of the cleaning pipe 31, and at least part of the positioning structure 5 is arranged in the limiting groove 40. When the clamping structure 4 is mounted on the mounting seat 2, the positioning structure 5 is pressed against the limiting groove 40 along the axial direction of the mounting hole 20.

[0075] Specifically, the positioning structure 5 can be an open end cover, and the positioning structure 5 can be welded and fixed to the outer periphery of the cleaning pipe 31, or the positioning structure 5 and the cleaning pipe 31 are fixedly connected by interference fit. The positioning structure 5 can also be an outwardly protruding limit platform set on the pipe wall of the cleaning pipe 31.

[0076] Among them, through the detachable connection between the clamping structure 4 and the mounting seat 2, the spray assembly 3 can be flexibly installed or removed according to the cleaning needs, making the maintenance and cleaning of the equipment more convenient. For example, in the cleaning state, the positioning structure 5 is fixed to the limiting groove 40 between the clamping structure 4 and the mounting seat 2, so that the cleaning pipe 31 and the spray head 32 connected thereto are fixed to the mounting hole 20 of the mounting seat 2. In the non-cleaning state, the clamping structure 4 can be removed from the mounting seat 2, so that the positioning structure 5 is separated from the limiting groove 40, and the spray assembly 3 can be taken out from the mounting hole 20.

[0077] Reference Figures 4 to 6 As shown, in some embodiments, the mounting seat 2 includes a slot 21 disposed on the outer peripheral surface of the mounting seat 2 , and the clamping structure 4 includes a buckle 41 engaged with the slot 21 , and the buckle 41 is disposed on the outer peripheral side of the slot 21 .

[0078] In some embodiments, the buckle 41 is annular, and includes a first sub-portion 411 and a second sub-portion 412. The first sub-portion 411 and the second sub-portion 412 are connected along a first direction to form the buckle 41, and the first direction is parallel to the plane where the buckle 41 is located, that is, the buckle 41 is formed by the first sub-portion 411 and the second sub-portion 412 being connected horizontally.

[0079] Optionally, the contact surface 410 between the pressing structure 4 and the positioning structure 5 is an inclined surface, and the contact surface gradually moves away from the mounting seat 2 along a direction close to the center of the mounting hole 20 .

[0080] After the buckle 41 is inserted into the slot 21, the positioning structure 5 can be pressed against the limiting slot 40 along the axial direction of the mounting hole 20. The first sub-portion 411 and the second sub-portion 412 are both semi-annular structures, and the docking direction of the first sub-portion 411 and the second sub-portion 412 is perpendicular to the axial direction of the buckle 41. During the process of the first sub-portion 411 and the second sub-portion 412 docking and approaching, the inclined contact surface 410 can convert the force in the docking direction into the force in the axial direction, thereby pressing the positioning structure 5 along the axial direction.

[0081] Specifically, the first sub-portion 411 and the second sub-portion 412 are connected by a fastener, and the distance between the first sub-portion 411 and the second sub-portion 412 along the docking direction can be adjusted by the fastener, such as a nut, to achieve disassembly and installation of the buckle 41.

[0082] Specifically, a sealing groove is provided at the end of the mounting seat 2 facing the positioning structure 5, and a sealing gasket is provided in the sealing groove. The sealing gasket is pressed between the mounting seat 2 and the positioning structure 5 to form a reliable seal to ensure the sealing inside the device.

[0083] In other embodiments, the buckle 41 may also include a plurality of hooks, and the hooks may be engaged with or separated from the slots 21 by rotation.

[0084] Reference Figures 4 to 6 As shown, in some embodiments, the positioning structure 5 is a perforated end cover 51 , which includes a central opening 510 , and the perforated end cover 51 is sleeved on the outer periphery of the cleaning tube 31 through the central opening 510 .

[0085] Optionally, the side wall spray device includes a positioning rod 61, a positioning plate 6 is provided on the mounting seat 2, a positioning hole 60 is opened on the positioning plate 6, the central axis of the positioning hole 60 is parallel to the central axis of the mounting hole 20, one end of the positioning rod 61 is connected to the open hole end cover 51, and the other end of the positioning rod 61 is plugged into the positioning hole 60.

[0086] Among them, the positioning plate 6 is fixedly connected to the mounting seat 2, and the positioning rod 61 is fixedly connected to the perforated end cover 51. For example, the positioning rod 61 can be welded and fixed to the perforated end cover 51. During the installation process, the perforated end cover 51 is fixed to the end of the mounting seat 2 by the clamping structure 4, and the positioning rod 61 is inserted into the positioning hole 60 of the positioning plate 6. During the disassembly process, after removing the clamping structure 4, the positioning rod 61 can be directly operated to remove the perforated end cover 51 and the spray assembly 3 from the mounting seat 2. The positioning rod 61 is used as an operating part, which is easy to grasp, so as to prevent the perforated end cover 51 or the spray assembly 3 from falling and hitting the staff, thereby reducing safety hazards.
