Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to a pot body installation mechanism and an experimental wet granulator. Background Art

[0002] The laboratory small wet granulator (hereinafter referred to as "granulator") is a commonly used granulation equipment, which is mainly composed of a pot body, a speed control box, a spray device and a motor, etc. It is often used to prepare granulated particles, improve drug stability and increase bioavailability. The pot body of the granulator is the core part of the wet granulator. It is equipped with a high-speed rotating centrifugal disk and a spray tube. When working, fluidizers and adhesives are added through the spray tube to wet the particles and form spherical particles under the action of centrifugal force. In the pot body, the material and performance of the bottom of the pot directly affect the granulation effect, the stable operation of the equipment, the safety of materials and the production efficiency.

[0003] At present, the pot bottom of the granulator is mainly divided into two types: plastic pot bottom and stainless steel pot bottom. Among them, the plastic pot bottom has the advantages of light weight and no rust, but its load-bearing capacity and high temperature resistance are relatively poor; the stainless steel pot bottom is more durable than the plastic pot bottom and can withstand high temperature and high pressure, but the cost is relatively high. Due to the large variety of experimental materials and large price differences, the sources of materials in the experimental stage are more or less. In order to obtain satisfactory experimental results, it is necessary to replace the pot body that matches the amount of materials to ensure the granulation effect of the granulator. Therefore, the prior art has made many improvements to the structure of the granulator, and proposed a wet granulator with a pot that can be quickly replaced. For example, the patent with the publication number CN210303966U proposed a laboratory wet granulator with a replaceable pot, which can freely replace granulation pots of different sizes to meet the needs of processing different quantities. Although this patent realizes the free replacement of the pot body of the granulator, the following problems are still common in the existing wet granulators with replaceable pots: it is difficult to position the pot body when replacing it, it is not convenient to install it quickly, and the locking is not firm after installation, the bottom of the pot is unstable, and the pot body is easily loosened. Summary of the invention

[0004] The utility model aims to provide a pot body installation mechanism, which can realize the rapid positioning and installation of the pot body, and has firm locking and good stability.

[0005] The technical solution adopted to achieve the purpose of this utility model is:

[0006] A pot body installation mechanism comprises a mounting seat body and a mounting through hole penetrating the mounting seat body, a positioning groove is provided on the top edge of the mounting seat body, and a circle of annular grooves is provided on the upper periphery of the mounting seat body.

[0007] Furthermore, the mounting through holes are divided into upper through holes, middle through holes, transition through holes and lower through holes from top to bottom, and are respectively divided into transition through holes, middle through holes, lower through holes and upper through holes in order from small to large in diameter.

[0008] Furthermore, a circle of connecting plates is provided on the outer periphery of the lower part of the mounting seat body, and the bottom surface of the connecting plates is higher than the bottom surface of the mounting seat body; one or more first bolt holes are opened on the mounting body at the bottom edge of the upper through hole, one or more second bolt holes are opened at the bottom of the mounting body, and one or more third bolt holes are opened at the bottom of the connecting plates.

[0009] Furthermore, at least one first ventilation hole and at least one second ventilation hole are provided at the bottom of the mounting seat body, wherein the first ventilation hole passes through the mounting seat body and is connected to the middle through hole, and the second ventilation hole passes through the mounting seat body and is connected to the lower through hole.

[0010] Furthermore, at least one locking groove is provided on the inner wall surface of the annular groove.

[0011] Furthermore, a chamfer is provided on the top edge of the mounting seat body.

[0012] Furthermore, the longitudinal section of the annular groove is V-shaped, one inner wall of the V-shaped annular groove is horizontally arranged, and the other inner wall is inclined; and the angle α between the two inner walls of the V-shaped annular groove is 20° to 50°.

[0013] Another purpose of the utility model is to provide an experimental wet granulator, which has a stable overall structure, good applicability and strong practicality.

[0014] The technical solution adopted to achieve another purpose of the utility model is:

[0015] An experimental wet granulator comprises the above-mentioned pot body mounting mechanism, and also comprises a frame, a stirring device, a granulating pot, a cutting device and an operating device; wherein the granulating pot is fixed to the top of the frame by the pot body mounting mechanism, and a discharging device connected to the inside of the granulating pot is provided at the bottom of the granulating pot; the stirring device is arranged below the granulating pot and connected to the inside of the granulating pot; the cutting device is arranged on the side of the granulating pot and connected to the inside of the granulating pot; the frame is fixedly connected to the operating device; a pot cover is also provided on the top of the granulating pot, and a feeding device and a respirator are provided on the pot cover.

[0016] The beneficial effects of the utility model are:

[0036] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1 to 10 As shown, a pot body mounting mechanism includes a mounting seat body 1 and a mounting through hole 2 penetrating the mounting seat body 1, a positioning groove 3 is also provided on the top edge of the mounting seat body 1; and a circle of annular grooves 4 are provided on the upper periphery of the mounting seat body 1.

[0039] The pot body mounting structure of this embodiment is mainly used in existing laboratory small-scale wet granulators, and is used to fix the granulation pot 14, and the granulation pot 14 is fixed on the pot body mounting mechanism, and the pot body mounting mechanism is on the bearing device of the granulator. When designing the granulation pot 14, its structure needs to match the corresponding structure in this embodiment. For example, the device of this embodiment can be applied to the laboratory replaceable pot wet granulator disclosed in the patent with publication number CN210303966U. When applied, other structures can be kept unchanged, and only the pot body mounting mechanism and the corresponding structure on the pot body can be adjusted.

[0040] In the present embodiment, a fixing seat 21 matching with the mounting seat body 1 is provided at the bottom of the granulating pot 14, and a positioning hole is provided on the fixing seat 21. When installing, the positioning hole is aligned with the positioning groove 3, and the positioning pin 22 can be inserted, thereby realizing the rapid positioning of the granulating pot 14. By inserting the positioning pin 22, the granulating pot 14 can be initially fixed to the mounting seat body 1. At this time, a part of the positioning pin 22 is located in the positioning groove 3, and a part is located in the positioning hole. A locking hole 23 matching with the annular groove 4 is also provided on the fixing seat 21. After the positioning pin 22 is installed, the locking bolt 24 is inserted from the locking hole 23 on the fixing seat 21, and the end of the locking bolt 24 is tightened after being pressed against the inner wall of the annular groove 4, thereby firmly fixing the granulating pot 14 on the pot body mounting mechanism. The structure of the utility model can be used to replace granulating pots 14 of different specifications and shapes as needed, such as Figures 7 to 10 shown.

[0041] The installation through hole 2 is mainly used to install the stirring system parts that match the pot body. In this embodiment, the positioning groove 3 is opened horizontally, and the positioning groove 3 is opened to facilitate observation from the positioning hole on the fixing seat 21 whether the positioning hole is aligned with the positioning groove 3. The annular groove 4 is provided to facilitate the insertion of the locking bolt 24. The annular groove 4 is used to replace the traditional bolt hole, and the alignment process is avoided without causing excessive friction hindrance to the fastening bolt 24. The locking bolt 24 can be directly pressed against the inner wall of the annular groove 4 to achieve quick assembly; in addition, after tightening the locking bolt 24, the locking bolt 24 will be subjected to the downward clamping force of the inner wall of the annular groove 4. When the locking bolt 24 is subjected to a large downward clamping force, it is not easy to slide outward, so that the locking bolt 24 is fixed more firmly, and the bolt is further prevented from loosening.

[0042] In this embodiment, the longitudinal cross-sectional shape of the annular groove 4 can be C-shaped, U-shaped, trumpet-shaped or V-shaped. In this embodiment, the longitudinal cross-sectional shape of the annular groove 4 is preferably V-shaped, and one inner wall of the V-shaped annular groove 4 is horizontally arranged, and the other inner wall is inclined; and the angle α between the two inner walls of the V-shaped annular groove 4 is 20°~50°, and the angle α between the two inner walls of the V-shaped annular groove 4 is preferably 30°.

[0043] like Figures 2 to 10 As shown, the mounting through hole 2 is divided into an upper through hole 201, a middle through hole 202, a transition through hole 203 and a lower through hole 204 from top to bottom, and in order of diameter from small to large, they are the transition through hole 203, the middle through hole 202, the lower through hole 204 and the upper through hole 201.

[0044] like Fig.11 and Fig.12 As shown, the installation through hole 2 is arranged in the above manner mainly to match the structure of the stirring device 13. It is mainly for the shaft in the stirring device 13 to pass through. The upper through hole 201, the middle through hole 202, the transition through hole 203 and the lower through hole 204 are arranged concentrically. The purpose of dividing the installation through hole 2 from top to bottom into the upper through hole 201, the middle through hole 202, the transition through hole 203 and the lower through hole 204 is to facilitate the installation of the gas seal seat. In this embodiment, the gas seal seat includes a first gas seal seat 25 and a second gas seal seat 26. During actual installation, the transition through hole 203 is used as the dividing part. The upper through hole 201 and the middle through hole 202 above the transition through hole 203 cooperate with the first gas seal seat 25, and the lower through hole 204 cooperates with the second gas seal seat 26. The main function of the gas seal seat in this embodiment is to prevent air from entering the stirring barrel, thereby ensuring the quality and stability of the wet particles. Specifically, the air seal seat forms a sealed environment by tightly fitting the opening of the mixing barrel, preventing the entry of air and external impurities, which can not only prevent the wet particles from being contaminated during the preparation process, but also avoid the drying and agglomeration of the wet particles due to exposure to the air.

[0045] like Figures 1 to 10As shown, a circle of connecting plates 5 is also provided on the lower periphery of the mounting seat body 1, and the bottom surface of the connecting plates 5 is higher than the bottom surface of the mounting seat body 1; one or more first bolt holes 6 are opened on the mounting body at the bottom edge of the upper through hole 201, one or more second bolt holes 7 are opened at the bottom of the mounting body, and one or more third bolt holes 8 are opened at the bottom of the connecting plate 5.

[0046] The connecting plate 5 is mainly used for fixing with the frame 12, and the first bolt hole 6, the second bolt hole 7 and the third bolt hole 8 are mainly used for bolt connection with the corresponding structure, wherein the first bolt hole 6 is used to cooperate with the corresponding bolt holes on the mounting seat body 1 and the first gas seal seat 25, so as to fix the mounting seat body 1 with the first gas seal seat 25; the second bolt hole 7 is used to cooperate with the corresponding bolt holes on the mounting seat body 1 and the second gas seal seat 26, so as to fix the mounting seat body 1 with the second gas seal seat 26; the third bolt hole 8 is used to cooperate with the corresponding bolt holes on the mounting seat body 1 and the frame 12, so as to fix the mounting seat body 1 with the frame 12, as shown in the figure. Fig.11 and Fig.12 shown.

[0047] In the actual design process, the number of the first bolt hole 6, the second bolt hole 7 and the third bolt hole 8 can be selected according to actual needs. In this embodiment, it is preferred that the number of the first bolt hole 6, the second bolt hole 7 and the third bolt hole 8 is four, and the four first bolt holes 6 are evenly distributed on the installation body at the bottom edge of the upper through hole 201, the four second bolt holes 7 are evenly distributed at the bottom of the installation body; and the four third bolt holes 8 are evenly distributed at the bottom of the connecting plate 5.

[0048] like Figure 3 , Figure 4 , Figure 6 and Fig.10 As shown, at the bottom of the mounting seat body 1, one or more first ventilation holes 9 and one or more second ventilation holes 10 are opened, wherein the first ventilation holes 9 pass through the mounting seat body 1 and are connected to the middle through hole 202, and the second ventilation holes 10 pass through the mounting seat body 1 and are connected to the lower through hole 204.

[0049] The first vent 9 and the second vent 10 in the utility model are mainly used for ventilation, heat dissipation and gas discharge. Specifically, during the stirring process, due to the effects of friction and shear force, a certain amount of heat will be generated inside the stirring device 13. The first vent 9 and the second vent 10 can allow air circulation to help the stirring device 13 dissipate heat and prevent the stirring system from overheating, thereby ensuring the stability and efficiency of the stirring process. In addition, after the drug powder is mixed with the wetting agent, some gas may be generated. If these gases are not discharged in time, they may cause the internal pressure of the stirring barrel to increase, affecting the stirring effect. The first vent 9 and the second vent 10 can allow the generated gas to be discharged smoothly, keeping the pressure inside the granulating pot 14 stable. The first vent 9 and the second vent 10 do not intersect with the second bolt hole 7, that is, the first vent 9, the second vent 10 and the second bolt hole 7 do not interfere with each other.

[0050] like Figure 2 As shown, the inner wall surface of the annular groove 4 is further provided with more than one locking groove 11 .

[0051] The number of locking grooves 11 matches the number of locking bolts 24. In this embodiment, preferably, the number of locking bolts 24 is four, that is, the number of locking holes 23 on the granulating pot 14 is also four, and the four locking holes 23 are evenly distributed on the fixing seat 21. The locking groove 11 matches the position of the locking bolt 24, which can guide and prevent the displacement of the locking bolt 24. When the locking bolt 24 is inserted, its end extends into the locking groove 11 to prevent the locking bolt 24 from being skewed when the locking bolt 24 is tightened.

[0052] like Figures 1 to 10 As shown, the top edge of the mounting seat body 1 is also chamfered.

[0053] The purpose of setting the chamfer is to play a certain guiding role, so that the fixing seat 21 at the bottom of the granulating pot 14 can be quickly connected with the top of the mounting seat body 1. In addition, it can also prevent the fixing seat 21 at the bottom of the granulating pot 14 from being scratched by the sharp edge of the mounting seat body 1 when the pot body is installed, which is convenient for the installation of the granulating pot 14.

[0054] Example 2

[0055] like Figures 1 to 12As shown, an experimental wet granulator includes the pot body mounting mechanism in Example 1, and also includes a frame 12, a stirring device 13, a granulating pot 14, a cutting device 15 and an operating device 16; wherein the granulating pot 14 is fixed to the top of the frame 12 by the pot body mounting mechanism, and the lower part of the granulating pot 14 is provided with a discharging device 17 connected to the inside of the granulating pot 14; the stirring device 13 is arranged below the granulating pot 14 and connected to the inside of the granulating pot 14; the cutting device 15 is arranged on the side of the granulating pot 14 and connected to the inside of the granulating pot 14; the frame 12 is fixedly connected to the operating device 16; the top of the granulating pot 14 is also provided with a pot cover 18, and the pot cover 18 is provided with a feeding device 19 and a respirator 20.

[0056] The frame 12, stirring device 13, granulating pot 14, cutting device 15, operating device 16, discharging device 17, pot cover 18, feeding device 19 and respirator 20 in this embodiment are all existing devices, and the connection method and working principle are all existing technologies. For example, the laboratory wet granulator with replaceable pot disclosed in the patent with publication number CN210303966U, the main difference between this embodiment and the patent is that the structure and matching method of the granulating pot 14 and the pot body mounting mechanism are different. In this embodiment, the bottom of the frame 12 is also provided with a universal wheel 27. When the granulator of this embodiment is working, the staff puts different materials into the granulating pot 14 from the feeding device 19 on the pot cover 18, controls the touch screen on the operating device 16, and controls the programmable PLC controller to make the equipment run according to the pre-set process parameters. After the materials are added, the stirring device 13 works, so that the stirring paddle of the stirring device 13 located inside the granulating pot 14 mixes and stirs the added materials. After stirring evenly, the adhesive is slowly added to the granulating pot 14 from the feeding device 19. The materials are fused with the adhesive to become wet soft materials. At this time, the cutting device 15 works, so that the granulating knife located in the granulating pot 14 cuts the soft materials into uniform wet granules. After granulation, the discharging device 17 is opened, and the materials can be discharged from the discharging device 17 to enter the next process, thereby realizing wet granulation.

[0057] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the scope of the utility model should be included in the protection scope of the utility model.
