Description

Technical Field

[0001] The present application relates to the technical field of spray drying, and more specifically, to a spray device for producing anhydrous calcium hydrogen phosphate. Background Art

[0002] As a pharmaceutical excipient, anhydrous calcium hydrogen phosphate is usually used as an additive in the pharmaceutical process, with the characteristics of buffering, enhancing solubility and stability. It is widely used in the preparation of pharmaceutical preparations such as tablets, capsules, and granules, which helps to improve the bioavailability and stability of drugs and improve the taste and solubility of drugs. In addition, anhydrous calcium hydrogen phosphate can also be used as a pharmaceutical excipient in the fields of dental products, oral calcium supplements, etc.

[0003] When producing anhydrous calcium hydrogen phosphate, the synthesized calcium hydrogen phosphate dihydrate slurry needs to be sent to a spray dryer for spray drying. During the spray drying process, the wet calcium hydrogen phosphate dihydrate will be atomized into tiny droplets and fully contact with hot air, thereby achieving rapid drying. The dried product is anhydrous calcium hydrogen phosphate.

[0004] At present, in the process of spray drying the calcium hydrogen phosphate dihydrate slurry, when the spraying is stopped or interrupted, the calcium hydrogen phosphate dihydrate slurry remaining in the pressure nozzle of the centrifugal atomizer in the spray dryer is easily heated and agglomerated, causing nozzle blockage, resulting in uneven spraying, which not only makes the particle size of the anhydrous calcium hydrogen phosphate product after drying different, but also makes the uneven spraying caused by the blockage easy to make the particle size of some calcium hydrogen phosphate dihydrate droplets too small and the water content too low, which is easy to cause the droplets to be over-dried during drying, resulting in the anhydrous calcium hydrogen phosphate product losing activity or quality degradation, and another part of the anhydrous calcium hydrogen phosphate product is easy to deteriorate and agglomerate during storage due to high water content, affecting the overall quality of the anhydrous calcium hydrogen phosphate product.

[0017] Beneficial effect: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. When the pumping of dihydrate calcium hydrogen phosphate slurry into the annular cover member is stopped or interrupted, the hydraulic pressure applied to the piston assembly gradually decreases, so that the piston assembly gradually moves upward under the action of its own elastic force, and continuously drives the plug part in the elastic filling assembly to be inserted into the pressure nozzle again and push out the residual liquid remaining in the pressure nozzle. When the slurry is pumped into the annular cover member again, the piston assembly moves downward under the action of hydraulic pressure, and the plug part is separated from the pressure nozzle again under the action of elastic force, so that the pressure nozzle is exposed again, thereby effectively avoiding the blockage of the pressure nozzle caused by interruption or cessation of production during the production process of anhydrous calcium hydrogen phosphate, thereby ensuring the production quality of anhydrous calcium hydrogen phosphate products.

[0018] 2. When the anti-blocking column inserted into the pressure nozzle in the plug part agglomerates due to the heat of the dihydrate calcium hydrogen phosphate slurry between the anti-blocking column and the pressure nozzle, resulting in the production of anhydrous calcium hydrogen phosphate. When the slurry is pumped into the annular cover member, the anti-blocking column is adhered and fixed in the pressure nozzle and cannot be detached from the pressure nozzle. In the process of increasing the hydraulic pressure in the inner cavity of the semi-cylinder shell and driving the piston assembly to move further downward, when the abutment part that moves synchronously with the piston assembly is aligned with the vertical through groove, the abutment part that originally blocked the moving direction of the vibrating hammer part quickly penetrates into the vertical through groove under the action of elastic force. Subsequently, under the elastic force of the power spring in the vibrating hammer part, the hammer seat quickly hits the end of the synchronous hitting rod in the plug part, generating a large impact force, forcing the anti-blocking column to detach from the pressure nozzle, thereby ensuring the continuity and stability of the production of anhydrous calcium hydrogen phosphate.

[0019] 3. After the abutment slide in the abutment head part is inserted into the vertical through groove, the abutment slide is disengaged from the horizontal groove under the action of the elastic force of the fourth return spring, which makes the anti-blocking column hit by the vibrating hammer part and disengaged from the pressure nozzle. In the process that the hydraulic pressure inside the semi-cylinder shell gradually decreases and returns to normal, the hollow seat that moves up synchronously with the upward piston assembly will not cause the movement of the piston assembly to be hindered due to the obstruction of the abutment slide. Therefore, when the production of anhydrous calcium hydrogen phosphate is completed and the slurry is stopped from being pumped into the semi-cylinder shell, the piston assembly can normally apply force to the anti-blocking column in the plug column part, so that the end of the anti-blocking column can enter the pressure nozzle again.

[0020] 4. After the abutment slider is disengaged from the transverse groove, the two switch terminals are contacted under the elastic force of the third reset spring in the indicating part, triggering the wireless signal transmitter to turn on and send out a prompt signal to remind the staff that after the production of anhydrous calcium hydrogen phosphate is completed, it is necessary to promptly insert the abutment slider that pops out of the transverse groove into the transverse groove again, and make the abutment head part abut against the vertical connecting rod of the vibrating hammer part, so that the vibrating hammer part can be restored to its initial state again, so as to ensure the normal progress of the subsequent anhydrous calcium hydrogen phosphate production.

A piston assembly is also sealed and slidably provided in the inner cavity of the annular cover member, and the piston assembly includes a conical portion 314, and the conical portion 314 is in a truncated cone or a cone shape. The elastic filling assembly includes a base portion connected to the inner cavity of the annular cover member, a brake portion, and a plug portion elastically sliding on the base portion and movably inserted into the pressure nozzle, and the end of the plug portion is fitted and abutted against the piston assembly; A vibrating hammer part is elastically slidable horizontally in the inner cavity of the base part, and the end of the synchronous hitting rod 311 is horizontally inserted into the inner cavity of the base part and is arranged opposite to the vibrating hammer part; The brake part includes a hollow stand 312 which is inserted at the bottom of the base part and connected to the piston assembly for sliding upward and downward movement.

When the piston assembly is in an initial state, the abutment portion is tightly against the vibrating hammer portion; The piston assembly includes an annular top seat 308, and when the piston assembly moves under the action of hydraulic pressure and drives the abutment part to move through the hollow seat 312, when the abutment part penetrates into the vertical groove 317, the vibrating hammer part hammers the end of the synchronous hitting rod 311 under the action of elastic force.

[0036] When the pumping of dihydrate calcium hydrogen phosphate slurry into the annular shell member is stopped or interrupted, the hydraulic pressure applied to the piston assembly gradually decreases, so that the piston assembly gradually moves upward under the action of its own elastic force, and the plug part in the elastic filling assembly is continuously driven to be inserted into the pressure nozzle again and the residual liquid remaining in the pressure nozzle is pushed out. When the slurry is pumped into the annular shell member again, the piston assembly moves downward under the action of hydraulic pressure, and the plug part is separated from the pressure nozzle again under the action of elastic force, so that the pressure nozzle is exposed again, thereby effectively avoiding the blockage of the pressure nozzle due to interruption or cessation of production in the production process of anhydrous calcium hydrogen phosphate, thereby ensuring the production quality of anhydrous calcium hydrogen phosphate products.

[0037] Reference Figures 1 to 5 , the embodiment of the present application provides a spray device for the production of anhydrous calcium hydrogen phosphate, the power structure includes a conical motor drum frame 10, and a driving motor 20 is connected to the bottom wall of the inner cavity of the conical motor drum frame 10; The annular cover member includes two semi-cylindrical shells 306 that can be assembled together in a sealable manner, and the shell assembled by the two semi-cylindrical shells 306 is sealed and connected to the bottom of the conical motor drum frame 10, and the rotating shaft of the driving motor 20 passes through the bottom of the conical motor drum frame 10 and the shell assembled by the two semi-cylindrical shells 306 and then connected to the outer disk 305, and the outer disk 305 is driven to rotate at a high speed by the driving motor 20; A liquid inlet pipeline 303 is fixedly connected to the side wall of one of the semi-cylindrical shells 306, and the connecting portion between the liquid inlet pipeline 303 and the semi-cylindrical shell 306 is located above the piston assembly and the outer spinner 305; An air hole is formed through the bottom of the semi-cylindrical shell 306 .

[0038] Reference Figure 5 , Figure 6 and Figure 8 The embodiment of the present application provides a spray device for producing anhydrous calcium hydrogen phosphate, wherein the base portion includes a base cylinder seat 310 connected to the inner cavity side wall of the semi-cylinder shell 306, the bottom opening of the base cylinder seat 310 is covered and connected with an end cover, and a hollow stand 312 is longitudinally movably inserted on the end cover; A reserved opening is provided on the base cylinder seat 310 at a position corresponding to the pressure nozzle position; Reference Figure 5 , Figure 6 The plug part includes an anti-blocking column 307 that slides horizontally on the base cylinder seat 310, one end of the anti-blocking column 307 is connected to the end-to-end connection seat 315, and the other end of the anti-blocking column 307 passes through the reserved opening and is movably inserted into the interior of the pressure nozzle; The end-end connection seat 315 is connected to a second return spring 316, and one end of the second return spring 316 away from the end-end connection seat 315 is connected to the base tube seat 310; One end of the synchronous hitting rod 311 is connected to the end-tail connecting seat 315, and the other end is horizontally inserted into the inner cavity of the base tube seat 310.

[0039] Reference Figures 6 to 8 , the embodiment of the present application provides a spray device for the production of anhydrous calcium hydrogen phosphate, the vibrating hammer part includes a hammer seat 320 which is arranged opposite to the end of the synchronous hitting rod 311; The bottom of the hammer seat 320 is provided with a vertical connecting rod 318 formed integrally therewith, and the hammer seat 320 and the vertical connecting rod 318 both slide horizontally in the inner cavity of the base cylinder seat 310; The hammer seat 320 and the vertical connecting rod 318 are both connected with a power spring 321, and the other end of the power spring 321 is connected to the inner cavity side wall of the base cylinder seat 310; The vertical through slot 317 is disposed on the vertical connecting rod 318 .

[0040] Reference Figure 6 , Figure 8 and Fig. 9 , the embodiment of the present application provides a spray device for producing anhydrous calcium hydrogen phosphate, the abutment part includes an abutment slider 322 and a fourth return spring 327; A horizontal groove communicating with the inner cavity of the hollow stand 312 is horizontally opened on the side wall of the hollow stand 312; The abutting slider 322 is inserted into the transverse groove in a horizontally movable manner, and one end of the fourth return spring 327 is connected to the end of the transverse groove; One end of the contact slider 322 away from the fourth return spring 327 extends out from the transverse groove.

[0041] When the vibrating hammer part is in the initial state, the abutment part in the braking part abuts against the vertical connecting rod 318 in the vibrating hammer part, the other end of the fourth return spring 327 abuts against the end of the abutting slide 322, and the power spring 321 is in a compressed state, and the fourth return spring 327 is in a fully compressed state.

[0042] Reference Figures 4 to 6The embodiment of the present application provides a spray device for producing anhydrous calcium hydrogen phosphate, wherein the piston assembly includes an annular top seat 308 located in the inner cavity of the housing assembled by two semi-cylindrical shells 306, and a conical portion 314 is disposed on the end of 308; The bottom of the annular top seat 308 is connected to a bottom annular seat which is sealed and slides in the inner cavity of the shell assembled by the two half-cylindrical shells 306; A first return spring 309 is connected to the bottom of the bottom ring seat, and the bottom end of the first return spring 309 abuts against the bottom wall of the inner cavity of the semi-cylindrical shell 306; The elastic filling assembly is located between the annular top seat 308 and the inner cavity side wall of the semi-cylindrical shell 306 , and when the plug part is in the initial state, the second return spring 316 is in a compressed state, and the end and tail connecting seat 315 is tightly against the side wall surface of the annular top seat 308 .

[0043] During the production process of anhydrous calcium hydrogen phosphate, under the elastic force of the second return spring 316 in the plug part, the end-to-end connection seat 315 gradually slides from the side wall surface of the annular top seat 308 to the side wall surface of the tapered portion 314. During this process, the anti-blocking column 307 is separated from the pressure nozzle and the reserved opening, respectively, so that the pressure nozzle is exposed again. Therefore, during the production process of anhydrous calcium hydrogen phosphate, the calcium hydrogen phosphate dihydrate slurry can be ejected through the pressure nozzle to form a liquid film or liquid filaments and contact the high-speed rotating outer spin disk 305. Due to the strong centrifugal force generated by the high-speed rotation of the outer spin disk 305, under the action of the centrifugal force, the liquid is thrown to the edge and thrown out from the edge in the form of fine mist, thereby generating fine and uniform droplets. The calcium hydrogen phosphate dihydrate droplets are preheated and dried to lose water to form anhydrous calcium hydrogen phosphate.

[0044] Under the action of centrifugal force, the liquid material is stretched into a thin film and continuously moves toward the edge of the spinner, and finally atomized into countless small droplets when leaving the edge. These small droplets have a small particle size and are evenly distributed, meeting the application requirements.

[0045] When the anti-blocking column 307 inserted into the pressure nozzle in the plug part agglomerates due to the heat of the dihydrate calcium hydrogen phosphate slurry between the anti-blocking column 307 and the pressure nozzle, resulting in the production of anhydrous calcium hydrogen phosphate. When the slurry is pumped into the annular cover member, the anti-blocking column 307 is adhered and fixed in the pressure nozzle and cannot be detached from the pressure nozzle. In the process of increasing the hydraulic pressure in the inner cavity of the semi-cylinder shell 306 and driving the piston assembly to move further downward, when the abutment part that moves synchronously with the piston assembly is aligned with the vertical through groove 317, the abutment part that originally blocked the moving direction of the vibration hammer part quickly penetrates into the vertical through groove 317 under the action of elastic force. Subsequently, under the elastic force of the power spring 321 in the vibration hammer part, the hammer seat 320 quickly hits the end of the synchronous hitting rod 311 in the plug part, generating a large impact force, forcing the anti-blocking column 307 to detach from the pressure nozzle, thereby ensuring the continuity and stability of the production of anhydrous calcium hydrogen phosphate.

[0046] After the abutment slide 322 in the abutment head part penetrates into the vertical through groove 317, under the elastic force of the fourth return spring 327, the abutment slide 322 disengages from the horizontal groove, which makes the anti-blocking column 307 hit by the vibrating hammer part and disengage from the pressure nozzle. In the process that the hydraulic pressure inside the semi-cylinder shell 306 gradually decreases and returns to normal, the hollow seat 312 that moves up synchronously with the upward piston assembly will not cause the movement of the piston assembly to be obstructed due to the obstruction of the abutment slide 322, so that when the production of anhydrous calcium hydrogen phosphate is completed and the slurry is stopped from being pumped into the semi-cylinder shell 306, the piston assembly can normally apply force to the anti-blocking column 307 in the plug column part, so that the end of the anti-blocking column 307 can enter the pressure nozzle again.

[0047] Embodiment 2, this embodiment is different from embodiment 1 in that: Figures 8 to 10 , the embodiment of the present application provides a spray device for the production of anhydrous calcium hydrogen phosphate, any one of the braking parts is also provided with an indicating part that cooperates with the abutment part; The indicating part includes a pair of switch terminals 329 arranged opposite to each other, a wireless signal transmitter 313 located in the inner cavity of the hollow stand 312, and a movable insulating frame 324 and a fixed insulating frame 325 located in the corresponding transverse groove. The wireless signal transmitter 313 is pre-installed with a battery. The wireless signal transmitter 313 is a wireless transmission module, which is an existing device that uses radio signals for wireless transmission, and will not be described in detail here. The movable insulating frame 324 is slidably connected to the fixed insulating frame 325. The movable insulating frame 324 is connected to a third return spring 326, and one end of the third return spring 326 away from 328 is connected to the end of the transverse groove. One of the switch terminals 329 is connected to the movable insulating frame 324, and the other switch terminal 329 is connected to the fixed insulating frame 325; The fixed insulating frame 325 is connected to the end of the transverse groove; When the vibrating hammer part is in the initial state and the abutting joint part abuts against the vertical connecting rod 318 in the vibrating hammer part, the end of the movable insulating frame 324 away from the third return spring 326 abuts against the end of the abutting slider 322, and at this time, the two switch terminals 329 in the indicating part do not contact each other; When the two switch terminals 329 are in contact, the wireless signal transmitter 313 is triggered to turn on and send out a prompt signal.

[0048] After the abutting slider 322 is separated from the transverse groove, the elastic force of the third reset spring 326 in the indicating part makes the two switch terminals 329 contact, triggering the wireless signal transmitter 313 to turn on and send a prompt signal to the external main controller, reminding the staff that after the anhydrous calcium hydrogen phosphate production work is completed, it is necessary to timely insert the abutting slider 322 ejected from the transverse groove into the transverse groove again, and make the abutting part abut against the vertical connecting rod 318 of the vibrating hammer part, so that the vibrating hammer part returns to the initial state again, so as to ensure the normal progress of the subsequent anhydrous calcium hydrogen phosphate production work. The main controller referred to in this article is a common existing technology that plays a control role, such as a computer, which will not be repeated here.

[0049] When the staff restores the vibrating hammer part to its initial state, they first remove the outer disk 305 from the rotating shaft of the driving motor 20, and then disassemble the two semi-cylinder shells 306 that were originally assembled together. Subsequently, the piston assembly is taken out from the inner cavity of the semi-cylinder shell 306, and the base part of the elastic filling assembly is removed from the side wall of the inner cavity of the semi-cylinder shell 306. After that, the end cover is removed from the bottom opening of the base cylinder seat 310, and finally the abutment slider 322 that pops out of the transverse groove is inserted into the transverse groove again, and the abutment head part is made to abut against the vertical connecting rod 318 of the vibrating hammer part, so that the vibrating hammer part is restored to its initial state again.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
