Description

Technical Field

[0001] This application relates to the technical field of wet granulators, and particularly to an observation window structure of a wet granulator that is convenient for cleaning. Background Art

[0002] A wet granulator is a commonly used industrial equipment, mainly used in the pharmaceutical, food, and chemical industries to form uniform granules from powder materials through a wet process. Its basic working principle is to mix powder materials with a liquid binder and form granules through mechanical extrusion and shearing actions.

[0003] In order to facilitate the observation of the working conditions inside the body of the wet granulator, some wet granulators are provided with an observation port at the upper end of the body, and a glass window is inlaid at the observation port, through which the staff can observe. During the use of the wet granulator, since there is a large amount of drug powder inside the body, the drug powder is easily adsorbed on the surface of the glass window, affecting the observation. And because the drug powder is adsorbed on the inner wall of the glass window, it is also inconvenient to clean.

[0004] In order to address the above problems, the glass window dust removal device disclosed in the publication number CN208032785U has an observation port provided on the middle side wall of the granulator main body. An observation cover is provided inside the observation port. A transparent glass plate is provided at one end of the observation cover close to the observation port. One side edge of the transparent glass plate is fitted and connected to an annular baffle on the side wall of the observation port. Empty slots are provided on both sides of the observation port. A movable rod is penetrated through the empty slots. One end of the movable rod is provided with a pull rod. Sealing telescopic plates are fixedly connected to both the upper and lower sides of the movable rod. The other end of the pull rod is provided with a connecting rod, and a cleaning brush is provided in the middle of the connecting rod. Empty slots are provided on both sides of the observation port, a movable rod is provided in the empty slots, and a cleaning brush is provided on the connecting rod of the movable rod. The dust on the inner wall of the transparent glass plate can be cleaned by the cleaning brush on the connecting rod through the pull rod. However, this structure is relatively complex, and during long-term use, the dust removal device is more likely to be damaged, and it is more troublesome to repair or replace after damage, and there is still room for optimization.

[0005] In order to ensure the simplicity of cleaning the observation window, this application provides an observation window structure of a wet granulator that is convenient for cleaning.

[0006] The observation window structure of a wet granulator that is convenient for cleaning provided by this application adopts the following technical solutions:

[0007] A structure of the observation window of a wet granulator facilitating cleaning, comprising a machine body with a base connected to its upper end. One side of the upper end of the base is rotatably connected to one side of an observation window cover, and the other side of the observation window cover is detachably connected to the other side of the base. A fixing frame is connected to the middle of the observation window cover, and an observation component is connected to the middle of the fixing frame; the observation component includes a glass window and a window pressing strip. First and second stepped grooves are sequentially formed on the inner side of the fixing frame. The glass window is detachably and washably embedded in the second stepped groove. A connecting seat protrudes from the groove wall of the first stepped groove, and a rotating groove is formed on the side wall of the connecting seat. A square rotating block is connected to one side of the window pressing strip, and the rotating groove is rotatably connected to the square rotating block, and the groove wall of the rotating groove restricts the spontaneous rotation of the square rotating block. The glass window is clamped between the window pressing strip and the inner wall of the fixing frame.

[0008] By adopting the above technical solution, the glass window is pressed and fixed by a window pressing strip arranged on the inner side of the fixing frame and capable of flipping. One side of the observation window cover is rotatably connected to the base, and the other side of the observation window cover is detachably connected to the base. The fixing frame can be turned up synchronously with the observation window cover. During the operation of the wet granulator, the operator can monitor the internal material mixing and granulation conditions in real time through the glass window to ensure that the process parameters are within the normal range; when the observation window part needs to be cleaned or replaced, the observation window cover can be opened in the shutdown state, and a new glass window can be directly replaced, and the old glass window can be taken away for separate cleaning. The solution is simple and easy to implement, and the equipment can continue to be processed after replacing the new glass window, ensuring the operation efficiency of the equipment.

[0009] Optionally, a buffer layer is connected to the side of the window pressing strip facing the glass window.

[0010] By adopting the above technical solution, when locking with the window pressing strip, the design of the buffer layer can prevent the window pressing strip from knocking and damaging the glass window from below, reducing the safety risk.

[0011] Optionally, a plurality of window pressing strips are evenly spaced around the circumferential direction of the glass window.

[0012] Optionally, the edges at the upper end of the fixing frame are smoothly transitioned.

[0013] By adopting the above technical solution, on the basis of protecting the lower side of the glass window, the smoothly transitioned edges can prevent the edges from knocking and damaging the glass window from above when installing the glass window.

[0014] Optionally, a first locking seat is connected to the outer periphery of the base, a second locking seat is connected to the outer periphery of the observation window cover, a locking bolt is detachably connected to the second locking seat. The locking bolt includes a connected head and a rod portion. The rod portion penetrates through the second locking seat from top to bottom and is detachably connected to the first locking seat.

[0015] By adopting the above technical solution, the locking bolt ensures that the observation window cover is tightly closed during operation, prevents internal moisture and dust from leaking, guarantees the sealing performance of the equipment, and improves the operation safety at the same time.

[0016] Optionally, the locking bolt further includes an extension portion disposed between the head portion and the rod portion, and the lower end of the extension portion abuts against the upper end surface of the second locking seat.

[0017] By adopting the above technical solution, during locking, the extension portion is used to make a certain distance between the head portion and the upper end surface of the second locking seat, so as to facilitate the staff to hold the head portion and rotate.

[0018] Optionally, a fixing seat is convexly provided on the outer periphery of the base, a rotating block is convexly provided on the outer periphery of the observation window cover, the rotating block is inserted into the fixing seat, the fixing seat is connected with a pin shaft that simultaneously inserts the rotating block and the fixing seat, and the inner wall of the rotating block fits with the outer peripheral surface of the pin shaft.

[0019] By adopting the above technical solution, when the observation window cover is turned up, due to the inner wall of the hole of the rotating block fitting with the outer peripheral surface of the pin shaft, the rotating block is affected by the frictional force and will remain in a state with a certain included angle with the base, which is convenient for the staff to disassemble and assemble the glass window.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. During the operation of the wet granulator, the operator can monitor the internal material mixing and granulation conditions in real time through the glass window, ensure that the process parameters are within the normal range.

[0028] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings.

[0029] The embodiment of this application discloses an observation window structure of a wet granulator that is convenient for cleaning. Refer to Figure 1 and Figure 2 , the observation window structure of the wet granulator that is convenient for cleaning includes a machine body 1. The structure and working principle of the machine body 1 are the same as those of the existing wet granulator, and will not be elaborated here. A base 11 is integrally formed on one side of the upper end of the machine body 1. The inside of the base 11 is hollow, and the base 11 is communicated with the inner cavity of the machine body 1.

[0030] A fixed seat 111 is integrally formed on the outer periphery of the base 11. A rotating block 21 is integrally formed on the outer periphery of the observation window cover 2. The rotating block 21 is inserted into the fixed seat 111. The fixed seat 111 is connected with a pin shaft 112 that simultaneously inserts the rotating block 21 and the fixed seat 111. The rotation connection between the rotating block 21 and the fixed seat 111 is realized by using the pin shaft 112, so as to realize the flip design of the observation window cover 2. The inner wall of the rotating block 21 is attached to the outer peripheral surface of the pin shaft 112. When the observation window cover 2 is turned up, affected by the frictional force, the rotating block 21 will maintain a state of a certain angle with the base 11, which is convenient for the staff to disassemble and assemble the glass window 41.

[0031] On the outer periphery of the base 11, on the other side opposite to the fixed seat 111, a first locking seat 113 is integrally formed. A threaded hole 114 is provided at the upper end of the first locking seat 113; on the outer periphery of the observation window cover 2, on the other side opposite to the rotating block 21, a second locking seat 22 is integrally formed. The middle part of the second locking seat 22 is penetrated. In order to achieve the locking function, the second locking seat 22 is detachably connected with a locking bolt 5. The locking bolt 5 includes a head 51, an extension part 52 and a rod part 53 which are integrally formed in sequence from top to bottom. The head 51 is in the shape of a gear, and the diameter of the extension part 52 is larger than that of the rod part 53. When the rod part 53 passes through the through hole of the second locking seat 22 from top to bottom and is locked in the threaded hole 114 of the first locking seat 113 by thread fitting, the lower end of the extension part 52 abuts against the upper end surface of the second locking seat 22. At this time, the observation window cover 2 is locked, and the wet granulator can work.

[0032] Refer to Figures 2 to 4 , an observation window cover 2 is covered on the upper end of the base 11. One side of the observation window cover 2 is rotatably connected to the base 11, and the other side of the observation window cover 2 is detachably connected to the base 11. The middle part of the observation window cover 2 is hollow and is embedded with a fixing frame 3. The fixing frame 3 is fixed to the inner side of the observation window cover 2 by screws. An observation assembly 4 is installed in the middle of the fixing frame 3, and the edges of the fixing frame 3 are smoothly transitioned.

[0033] The observation assembly 4 includes a glass window 41 and a window pressing strip 42. A first stepped groove 31 and a second stepped groove 32 are sequentially provided on the inner side of the fixing frame 3. The glass window 41 is detachably and washably embedded in the second stepped groove 32. A connecting seat 311 is integrally formed on the groove wall of the first stepped groove 31. A rotating groove 312 is provided on the side wall of the connecting seat 311. The rotating groove 312 is a square groove. A square rotating block 421 is integrally formed on one side of the window pressing strip 42. The rotating groove 312 is rotatably connected to the square rotating block 421 through a rotating shaft. A plurality of window pressing strips 42 are circumferentially and evenly spaced around the glass window 41. In the embodiment of the present application, four window pressing strips 42 are taken as an example for illustration. A buffer layer 422 is adhered to the side of the window pressing strip 42 facing the glass window 41. In the embodiment of the present application, the buffer layer 422 is taken as a rubber layer for illustration.

[0034] It can be toggled to switch the square rotating block 421 between two states: perpendicular to the connecting seat 311 and horizontal to the connecting seat 311, but the rotation of the square rotating block 421 is restricted by the groove wall of the rotating groove 312. When the square rotating block 421 is horizontal to the connecting seat 311, the buffer layer 422 abuts against the inner wall of the glass window 41, and the glass window 41 is clamped between the buffer layer 422 and the inner wall of the fixing frame 3, and observation can be made through the unobscured part of the glass window 41 from the outside.

[0035] The implementation principle of the wet granulator observation window structure that is easy to clean in the embodiment of the present application is as follows: during the operation of the wet granulator, the operator can monitor the material mixing and granulation conditions inside in real time through the glass window 41 to ensure that the process parameters are within the normal range; when the observation window part needs to be cleaned or replaced, the locking bolt 5 can be removed in the shutdown state to unlock the observation window cover 2, and then the observation window cover 2 can be flipped up. At this time, the glass window 41 can be flipped up and exposed to the outside, and the square rotating block 421 can be moved to remove the old glass window 41, and then the new glass window 41 can be replaced and installed, and then the observation window cover 2 can be re-covered and re-locked to continue processing. According to the degree of wear, the old glass window 41 can be cleaned or directly discarded.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
