Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical equipment technology, and in particular relates to a self-cleaning structure for an adjustable nozzle. Background Technology

[0002] The applicant has been continuously designing and improving hoppers and their cleaning processes for a long time. Since 2012, the applicant has successively applied for authorization announcements for an automatic hopper conveying cleaning and drying device (CN102527684B), a hopper cleaning chamber (CN102580970B), a high-sealing cleaning mechanism (CN112756359A), and a manual cleaning and purging structure for a hopper cleaning machine (CN214918667U). The hopper cleaning chamber, as a cleaning device specifically for hoppers, has been launched and is currently in use as a mature product. However, the applicant continues to improve the existing equipment based on problems reflected by customers during use, taking customer needs as the basis for further research and development.

[0003] Currently, because existing equipment uses an integrated large viewing glass structure, during the cleaning hopper process, dirt will splash onto the glass with the airflow or water flow, which is not conducive to workers observing the cleaning status from the outside, affecting aesthetics and hygiene. However, since the hopper cleaning chamber is usually used in conjunction with other hopper automatic conveying and cleaning devices, it is not possible to stop the operation to clean the glass at any time, and it is time-consuming and laborious for workers to clean the inside. Therefore, it is necessary to develop a self-cleaning structure with adjustable nozzles to facilitate cleaning the inside of the cleaning chamber at any time during the hopper cleaning process. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning structure with an adjustable nozzle. A motor can drive the nut block to rotate, which in turn drives the self-cleaning pipe to rise and fall. This, in turn, drives the rotating rod to rotate via the first and second connecting rods. At the same time, the universal coupling can drive all the nozzles to rotate, making it easy to adjust the water flow direction and keep the glass door clean, thus solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A self-cleaning structure with an adjustable nozzle includes a cleaning chamber body and a cleaning pipe disposed inside the cleaning chamber body. The cleaning pipe includes a hopper cleaning pipe for cleaning the hopper and a self-cleaning pipe for self-cleaning. The self-cleaning pipe is in the shape of a regular polygon and is disposed at the upper end of the cleaning chamber. Two sets of fixing blocks are provided on any two centrally symmetrical sides of the regular polygon. A nozzle is rotatably connected between each set of fixing blocks. The self-cleaning pipes arranged in a regular polygon can be close enough to the inner wall of the cleaning chamber, so that the nozzle can spray liquid onto the inner wall of the cleaning chamber.

[0007] The adjustment mechanism, located on the top of the cleaning chamber, is used to adjust the nozzle angle, which can increase the spray range and make the cleaning more thorough.

[0008] Optionally, the adjustment mechanism includes a motor fixedly connected to the top of the cleaning chamber body, a self-cleaning tube slidably disposed inside the cleaning chamber body, a nut block fixedly connected to one side of the self-cleaning tube, a reciprocating screw threadedly connected to the top of the nut block, the top of the reciprocating screw extending to the top of the cleaning chamber body and fixedly connected to the output shaft of the motor, a rotating block rotatably sleeved on the outer wall of the reciprocating screw, a first connecting rod rotatably connected to one side of the rotating block, a second connecting rod slidably sleeved on the outer wall of the first connecting rod, rotating rods rotatably connected between the left and right sets of fixed blocks, and multiple nozzles respectively fixedly sleeved on the rotating rods between each set of fixed blocks. The end of the second connecting rod away from the first connecting rod is fixedly connected to one of the rotating rods, so that the reciprocating screw, self-cleaning tube and connecting rod form a triangle, so that when the self-cleaning tube moves up and down, the nozzles are driven to rotate through the connecting rods. Two adjacent rotating rods are connected by a universal coupling, so that multiple nozzles can rotate together.

[0009] Optionally, a sliding hole is provided at the end of the second connecting rod away from the rotating rod, and a limiting block is slidably provided on the inner wall of the sliding hole. The end of the first connecting rod near the second connecting rod is fixedly connected to the limiting block to prevent the first connecting rod from disengaging from the second connecting rod and to facilitate the limiting of the self-cleaning tube.

[0010] Optionally, the nozzle is provided with a conical guide slope, which causes the water flow to expand radially outward when it is sprayed from the nozzle, thereby increasing the spraying area of ​​the water flow.

[0011] Optionally, the self-cleaning pipe arranged in a regular polygonal shape includes eight pipe unit components, which are interconnected by a connecting part. The connecting part includes a first interface and a second interface with a stepped fit, as well as a first arc-shaped block and a second arc-shaped block located at the connection point, making it easy to install, disassemble and maintain.

[0012] Optionally, the second interface is provided with an annular sealing ring, and the inner wall of the first interface is provided with an annular groove that mates with the annular sealing ring, which can increase its sealing effect.

[0013] Optionally, a connecting block is fixedly connected to one side of the first arc-shaped block, and a rectangular opening corresponding to the connecting block is opened on one side of the second arc-shaped block. The connecting block and the second arc-shaped block are rotatably connected via a rotating shaft. A first fixing plate is fixedly connected to one side of the first arc-shaped block, and a locking screw is fixedly connected to one side of the first fixing plate. A second fixing plate is fixedly connected to one side of the second arc-shaped block, and a through hole is opened on one side of the second fixing plate. One end of the locking screw passes through one side of the through hole and is threaded with a locking nut. The two arc-shaped blocks can be fixed together by the locking screw and the locking nut, thereby fixing and locking the two interfaces.

[0014] Optionally, the nozzle is a multi-head nozzle with at least two nozzles, thereby further increasing the cleaning range.

[0015] The embodiments of the present invention have the following beneficial effects:

[0016] The motor can drive the nut block to rotate, which in turn drives the self-cleaning pipe to rise and fall. This, in turn, drives the rotating rod to rotate via the first and second connecting rods. At the same time, the universal coupling can drive all the nozzles to rotate, making it easy to adjust the water flow direction and keep the glass door clean.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0030] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] Example 1

[0032] Please see Figures 1-3 and Figure 8As shown, this embodiment provides a self-cleaning structure with an adjustable nozzle, including a cleaning chamber body 1 and a cleaning pipe disposed inside the cleaning chamber body 1. The cleaning pipe includes a hopper cleaning pipe for cleaning the hopper and a self-cleaning pipe 2 for self-cleaning. The self-cleaning pipe 2 is a regular polygon and is disposed at the upper end of the cleaning chamber. Two sets of fixing blocks 9 are provided on any two centrally symmetrical sides of the regular polygon. A nozzle 21 is rotatably connected between each set of fixing blocks 9. The self-cleaning pipe 2 is connected to a water inlet pipe. The water pressure in the water inlet pipe causes water to flow out from the cleaning pipe. The self-cleaning pipe 2 arranged in a regular polygon can be close enough to the inner wall of the cleaning chamber body 1, which makes it easy for the nozzle 21 to spray liquid onto the inner wall of the cleaning chamber body 1.

[0033] An adjustment mechanism, located on the top of the cleaning chamber body 1, is used to adjust the angle of the nozzle 21, thereby increasing the spray range and enabling thorough cleaning without dead angles.

[0034] In one aspect of this embodiment, such as Figure 1 and Figure 3 As shown, the adjustment mechanism includes a motor 5 fixedly connected to the top of the cleaning chamber body 1, a self-cleaning pipe 2 slidably disposed inside the cleaning chamber body 1, a nut block 41 fixedly connected to one side of the self-cleaning pipe 2, a reciprocating screw 4 threadedly connected to the top of the nut block 41, the top of the reciprocating screw 4 extending to the top of the cleaning chamber body 1 and fixedly connected to the output shaft of the motor 5, a rotating block 6 rotatably sleeved on the outer wall of the reciprocating screw 4, a first connecting rod 7 rotatably connected to one side of the rotating block 6, a second connecting rod 8 slidably sleeved on the outer wall of the first connecting rod 7, a rotating rod 10 rotatably connected between the left and right sets of fixed blocks 9, multiple nozzles 21 respectively fixedly sleeved on the rotating rod 10 between each set of fixed blocks 9, the end of the second connecting rod 8 away from the first connecting rod 7 fixedly connected to one of the rotating rods 10, and two adjacent rotating rods 10 connected by a universal coupling 11. By starting the motor 5, the nut block 41 can be driven to move up and down repeatedly, which in turn can drive the self-cleaning tube 2 to move up and down. The movement of the self-cleaning tube 2 can drive the first connecting rod 7 to slide within the second connecting rod 8, and at the same time rotate on one side of the rotating block 6, thereby driving the rotating rod 10 to rotate. The rotating rod 10 can drive all the nozzles 21 to rotate back and forth through the universal coupling 11, so that they can adjust the spray direction back and forth, making the cleaning more thorough.

[0035] In one aspect of this embodiment, such as Figure 3 and Figure 4 As shown, a sliding hole 12 is provided at the end of the second connecting rod 8 away from the rotating rod 10. A limiting block 13 is slidably provided on the inner wall of the sliding hole 12. The end of the first connecting rod 7 close to the second connecting rod 8 is fixedly connected to the limiting block 13. The limiting block 13 can limit the first connecting rod 7 and the second connecting rod 8 to prevent the first connecting rod 7 from disengaging from the second connecting rod 8.

[0036] Example 2

[0037] An improvement based on Embodiment 1: In one aspect of this embodiment, as follows Figure 6 and Figure 7 As shown, the self-cleaning pipe 2 arranged in a regular polygon includes eight pipe unit components 22. The eight pipe unit components 22 are connected to each other through a connecting part 23. The connecting part 23 includes a first interface 231 and a second interface 232 with a stepped fit, as well as a first arc-shaped block 24 and a second arc-shaped block 25 located at the connection point. The first interface 231 and the second interface 232 can be spliced ​​and fixed to make it convenient to use.

[0038] In one aspect of this embodiment, such as Figure 6 and Figure 7 As shown, a connecting block 26 is fixedly connected to one side of the first arc-shaped block 24, and a rectangular opening 27 corresponding to the connecting block 26 is opened on one side of the second arc-shaped block 25. The connecting block 26 and the second arc-shaped block 25 are rotatably connected through a rotating shaft 28. A first fixing plate 29 is fixedly connected to one side of the first arc-shaped block 24, and a locking screw 30 is fixedly connected to one side of the first fixing plate 29. A second fixing plate 32 is fixedly connected to one side of the second arc-shaped block 25, and a through hole 33 is opened on one side of the second fixing plate 32. One end of the locking screw 30 passes through one side of the through hole 33 and is threaded with a locking nut 31. The first interface 231 and the second interface 232 can be clamped by the first arc-shaped block 24 and the second arc-shaped block 25. The second fixing plate 32 can be fixed on the first fixing plate 29 by rotating the locking nut 31, making it easy to disassemble.

[0039] In one aspect of this embodiment, such as Figure 6 As shown, the second interface 232 is provided with an annular sealing ring 233, and the inner wall of the first interface 231 is provided with an annular groove that cooperates with the annular sealing ring 233. The sealing between the first interface 231 and the second interface 232 can be increased by setting the annular sealing ring 233.

[0040] Example 3

[0041] Improvements based on Example 1: such as... Figure 2 and Figure 5 As shown, the nozzle 21 is provided with a conical guide slope 3, which can increase the spray range of the water flow.

[0042] In one aspect of this embodiment, such as Figure 5 As shown, nozzle 21 is a multi-head nozzle with at least two nozzles 211, which increases its cleaning range and makes it cleaner.

[0043] The usage process and working principle of the technical solution of this invention are as follows:

[0044] In use, the self-cleaning pipe 2 is connected to a water source, and water flows out from the fixed block 9 through the self-cleaning pipe 2. At the same time, the motor 5 is started, which drives the reciprocating screw 4 to rotate. The rotation of the reciprocating screw 4 drives the nut block 41 to move up and down, thereby driving the self-cleaning pipe 2 to move up and down. The movement of the self-cleaning pipe 2 can drive the second connecting rod 8 to move. The movement of the second connecting rod 8 can drive the first connecting rod 7 to slide within the second connecting rod 8. While sliding, it rotates on one side of the rotating block 6, thereby driving the rotating rod 10 to rotate. The rotation of the rotating rod 10 can drive the nozzle 21 to rotate. The nozzle 21 can drive the other nozzles 21 to rotate through the universal coupling 11. The rotation of the nozzle 21 can adjust the direction of the water jet, thereby achieving reciprocating rinsing of the glass door to facilitate observation of the interior.
