Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical machinery and equipment technology, and in particular relates to an automated rotary hopper cleaning structure. Background Technology

[0002] In the pharmaceutical manufacturing industry, the storage, transfer and collection of materials are involved. In this process, hoppers are commonly used production containers. They are usually composed of a detachable hopper cover and a hopper body with a hollow chamber. Some hoppers are also equipped with rollers at the bottom as movable hopper trolleys.

[0003] Traditional hopper cleaning lifting mechanisms are hand-cranked winches, which are complex in structure, costly, and slow in lifting speed. Prolonged hand-cranking can cause arm fatigue. Existing technologies have poor cleaning effects on hoppers and are inconvenient to use. In addition, the overall weight of the hand-cranked winch structure is large, making it only suitable for ground installation, but some pharmaceutical factories have inconvenient ground conditions for installation. Therefore, based on the above problems, the applicant has developed a lifting hopper cleaning lifting structure that has a smaller footprint, can be installed against a wall, and is more labor-saving. Summary of the Invention

[0004] The purpose of this invention is to provide an automated rotary hopper cleaning structure and its usage method. This technical solution enables effective flushing and cleaning of the inner wall of the hopper, facilitating its use. At the same time, the use of a bonding component to drive the cleaning brush to adhere to the inner wall of the hopper body results in a more thorough cleaning, 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] An automated rotary hopper cleaning structure includes a hopper body and further includes:

[0007] A hollow column, which is fixed to a vertical wall by fixed brackets at its upper and lower ends;

[0008] The sliding assembly includes a sliding sleeve slidably fitted onto the column, a cleaning bracket connected to one side of the sliding sleeve, a handle structure linked to the sliding sleeve, a pulley assembly disposed at the upper end of the column, and a counterweight block connected to the sliding sleeve through the pulley assembly and disposed inside the column.

[0009] A cleaning cover is provided, and a sleeve is fixed inside the cleaning bracket, with the cleaning cover fixed to the bottom end of the sleeve.

[0010] The cleaning cover is provided with a pin that is compatible with the hopper body to be cleaned.

[0011] The reciprocating assembly has a lifting shaft inserted into the sleeve. An adjusting block is fixed at the bottom of the lifting shaft. Spray nozzles for cleaning are fixed at the four corners of the adjusting block. The reciprocating assembly is located on the upper side of the cleaning bracket to drive the spray nozzles to reciprocate and clean the inner wall of the hopper.

[0012] And a rotating cleaning assembly used in conjunction with the reciprocating assembly, wherein each of the four ends of the adjusting block is provided with a cleaning brush, and the rotating cleaning assembly is located on the upper side of the cleaning bracket to drive the four nozzles and four cleaning brushes to rotate and clean.

[0013] Four sets of bonding components are respectively located between the adjusting block and the four cleaning brushes to drive the four cleaning brushes to bond to the inner wall of the hopper body;

[0014] A compression positioning component is provided between the cleaning cover and the adjusting block to compress and tighten the four sets of bonding components when the cleaning brush has not entered the hopper body.

[0015] Optionally, the handle structure is connected to the sliding sleeve via a cleaning bracket, and includes a first handle and a second handle connected to the lower position of the cleaning bracket, wherein the horizontal height of the second handle is lower than the horizontal height of the first handle.

[0016] Optionally, the pulley assembly includes a pulley disposed on the top of the column and a steel wire rope that cooperates with the pulley. One end of the steel wire rope is connected to the cleaning bracket, and the other end extends into the column and is connected to the counterweight.

[0017] Optionally, buffer pads are provided between the fixed brackets at the upper and lower ends of the column and the sliding sleeve. The sliding sleeve is limited between the upper and lower buffer pads and also includes a locking buckle fixed to the vertical wall. The sliding sleeve has a locking position where it rotates around the column to be close to the vertical wall so that the handle structure is connected to the locking buckle, and a working position where it rotates around the column to be away from the vertical wall so that the washing bracket corresponds to the hopper body.

[0018] Optionally, the reciprocating assembly includes a U-shaped frame fixed to the top of the cleaning bracket, a threaded plate sliding inside the U-shaped frame, a reciprocating screw rotating inside the U-shaped frame, the threaded plate being threadedly connected to the circumferential surface of the reciprocating screw, the lifting shaft rotating inside the threaded plate, and a drive motor fixed to the top of the U-shaped frame, the drive motor being connected to the reciprocating screw via a coupling.

[0019] Optionally, the rotating cleaning assembly includes a first gear fixed to the surface of a reciprocating lead screw, a fixed plate fixed inside the U-shaped frame, a fixed rotating cylinder rotating inside the fixed plate, a cross fixed inside the fixed rotating cylinder, a second gear meshing with the first gear fixed to the surface of the fixed rotating cylinder, a sliding groove inside the lifting shaft, the cross sliding within the lifting shaft, an annular slider sliding within the sliding groove, the annular slider fixed to the surface of the cross, a first connecting groove and four second connecting grooves inside the adjusting block, the four second connecting grooves respectively connected to four nozzles, the first connecting groove and the four second connecting grooves being connected, a connecting pipe rotating inside the adjusting block, and a cleaning pipe rotatably connected to the side end of the connecting pipe.

[0020] Optionally, each of the bonding components includes a U-shaped plate fixed to the side end of the adjusting block, two limiting rods fixed inside the U-shaped plate, a common sliding plate sliding on the surface of the two limiting rods, a connecting rod fixed to the side end of the sliding plate, a cleaning brush fixed to the side end of the connecting rod, two springs fixed to the side end of the sliding plate, both springs fixed to the side end of the adjusting block, and the two springs respectively sleeved on the surface of the two limiting rods.

[0021] Optionally, each of the four slide plates has a pressing rod fixed to its top, and the bottom of the cleaning cover has a pressing ring fixed to its bottom. All four pressing rods are in contact with the inclined surface of the pressing ring.

[0022] In this application, when the hopper body is fed to fit against the cleaning cover, the drive motor is started to rotate the reciprocating screw. The rotation of the reciprocating screw causes the threaded plate to move up and down reciprocally. The threaded plate causes the lifting shaft to move up and down reciprocally. The lifting shaft, through the adjusting block, drives four nozzles and four cleaning brushes to move up and down reciprocally within the hopper body for rinsing and scrubbing. Simultaneously, the reciprocating screw drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear then drives the fixed drum to rotate, which in turn drives the slide to rotate. The slide's rotation then drives the lifting shaft to move up and down reciprocally. When in motion, the lifting shaft rotates, and the lifting shaft drives four nozzles and four cleaning brushes to rotate inside the hopper via the adjusting block. After the cleaning brushes descend with the adjusting block, the extrusion rod leaves the inclined surface of the extrusion ring, and the extrusion rod loses pressure. Through the elasticity of the spring, it drives the sliding plate to move. The sliding plate pushes the cleaning brushes outward via the connecting rod. The cleaning brushes are pressed against the inner wall of the hopper. When the adjusting block drives the cleaning brushes to rotate, it can clean the inner wall of the hopper. Water is input through the cleaning pipe, and the water is sent to the connecting pipe through the cleaning pipe. After passing through the first connecting groove and the second connecting groove, it is sent to the nozzles and sprayed out.

[0023] The embodiments of the present invention have the following beneficial effects:

[0024] In this technical solution, the device uses a sliding sleeve fitted onto the column and connected to the cleaning bracket. Through the cooperation of the pulley assembly, counterweight, sliding sleeve and cleaning bracket, the manual force applied to the handle structure is reduced, making operation easier. At the same time, the lifting device is installed on the wall, saving floor space. When not in use, the sliding component automatically moves upward, without affecting the passage of people or equipment below.

[0025] In this technical solution, the reciprocating component drives the nozzle to move up and down in the hopper body for cleaning. At the same time, the reciprocating component synchronously drives the hopper body and the cleaning brush to rotate for cleaning, which can effectively flush and clean the inner wall of the hopper body, making it convenient to use. Meanwhile, the adhering component drives the cleaning brush to adhere to the inner wall of the hopper body, making the cleaning more thorough. At the same time, the squeezing positioning component can retract the four cleaning brushes before they enter the hopper body, making it convenient for them to enter the hopper body.

[0026] 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.

[0038] 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.

[0039] 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.

[0040] Example 1

[0041] Please see Figures 1-8 As shown, this embodiment provides an automated rotary hopper cleaning structure, including a hopper body 9, a hollow column 1, and a sliding assembly. The sliding assembly includes a sliding sleeve 2 slidably fitted on the column 1, a cleaning bracket 3 connected to one side of the sliding sleeve 2, a handle structure linked with the sliding sleeve 2, a pulley assembly set at the upper end of the column 1, and a counterweight block 6 set inside the column 1 and connected to the sliding sleeve 2 through the pulley assembly.

[0042] The cleaning cover 4 is equipped with a pin 41 that matches the hopper body 9 to be cleaned; the sliding sleeve 2 is fitted onto the outside of the column 1 to connect the cleaning cover 4. The weight of the internal counterweight 6 of the column 1 is slightly heavier than that of the external sliding sleeve 2, ensuring that the lifting process is easy and effortless. During operation, the slider is pulled down to align the cleaning cover 4 with the opening of the hopper body 9 and lock it with the pin.

[0043] The handle structure is connected to the sliding sleeve 2 via the cleaning bracket 3, and includes a first handle 51 and a second handle 52 connected to the lower part of the cleaning bracket 3. The horizontal height of the second handle 52 is lower than that of the first handle 51. With two sets of handle structures, when the sliding sleeve 2 is at the upper end of the column 1, the sliding component can be pulled down by the second handle 52, which is at a lower horizontal height. When the sliding sleeve 2 moves down, the first handle 51 can be connected to the locking buckle 8 on the wall to lock the position of the sliding component.

[0044] The pulley assembly includes a pulley 71 located at the top of the column 1, and a wire rope 72 that cooperates with the pulley 71. One end of the wire rope 72 is connected to the cleaning bracket 3, and the other end extends into the column 1 and is connected to the counterweight 6.

[0045] The column 1 is fixed to the vertical wall by the fixing brackets 11 at its upper and lower ends.

[0046] Upper and lower buffer pads 12 are respectively provided between the fixed brackets 11 at the upper and lower ends of the column 1 and the sliding sleeve 2, and the sliding sleeve 2 is limited to the upper and lower buffer pads 12.

[0047] like Figure 2 As shown, it also includes a locking buckle 8 fixed to the vertical wall. The sliding sleeve 2 has a locking position (position A or position B in the figure) where it rotates around the column 1 to be close to the vertical wall so that the handle structure is connected to the locking buckle 8, and a working position (position C in the figure) where it rotates around the column 1 to be away from the vertical wall so that the washing bracket 3 corresponds to the hopper body 9. When not in use, the sliding sleeve 2 is rotated to one side and connected to the handle through the locking buckle 8 to prevent the slider from falling due to external factors.

A first connecting groove 36 and four second connecting grooves 29 are provided inside the adjusting block 18. A connecting pipe 32 is provided, and a cleaning pipe 31 is rotatably connected to the side end of the connecting pipe 32. When the hopper body 9 is fed to fit against the cleaning cover 4, the drive motor 28 is started to drive the reciprocating screw 35 to rotate. The rotation of the reciprocating screw 35 drives the threaded plate 14 to move up and down reciprocally. The threaded plate 14 drives the lifting shaft 13 to move up and down reciprocally. The lifting shaft 13 drives the four nozzles 19 and four cleaning brushes 23 to move up and down reciprocally within the hopper body 9 through the adjusting block 18. The process involves rinsing and scrubbing, while simultaneously driving the first gear 36 to rotate via the reciprocating screw 35. The rotation of the first gear 36 drives the second gear 37 to rotate, which in turn drives the fixed rotating drum 38 to rotate. The rotation of the fixed rotating drum 38 drives the sliding groove 30 to rotate, which in turn drives the lifting shaft 13 to rotate as it moves up and down. The lifting shaft 13, through the adjusting block 18, drives the four nozzles 19 and four cleaning brushes 23 to rotate within the hopper body 9.

The four squeezing rods 17 are in contact with the inclined surface of the squeezing ring 16. After the cleaning brush 23 descends with the adjusting block 18, the squeezing rods 17 leave the inclined surface of the squeezing ring 16, and the squeezing rods 17 lose pressure. The spring 25 pushes the sliding plate 24 to move. The sliding plate 24 pushes the cleaning brush 23 outward through the connecting rod 22. The cleaning brush 23 is pressed against the inner wall of the hopper body 9. When the adjusting block 18 drives the cleaning brush 23 to rotate, it can clean the inner wall of the hopper body 9. Water is input through the cleaning pipe 31 and sent to the connecting pipe 32 through the cleaning pipe 31.
