Description

Technical Field

[0001] This utility model relates to the field of granule pharmaceutical production technology, and in particular to a uniform drying device for preparing gallstone-expelling and choleretic granules. Background Technology

[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] Pediatric litholytic granules are a commonly used drug for treating liver and gallbladder diseases. During the production process of pediatric litholytic granules, a drying device is used to dry the initially produced granules which contain moisture.

[0004] In related technologies, when drying choleretic and litholytic granules, they are spread evenly in a drying oven. It is necessary to spread the granules evenly to avoid excessively thick stacking of the drug granules. This results in a lot of time being wasted in the preparation operations before drying. At the same time, due to lack of experience and other reasons, the choleretic and litholytic granules are still not spread evenly, resulting in uneven drying. It takes more time to ensure that the choleretic and litholytic granules are completely dried. Utility Model Content

It has the advantages of using air to blow the choleretic and litholytic granules up and down at the bottom of the round tank, and using waste heat to heat the choleretic and litholytic granules on the outside of the device to improve the uniformity of drying. It solves the technical problems of wasting a lot of time in drying choleretic and litholytic granules by spreading them flat in the drying box, and uneven drying caused by uneven spreading of choleretic and litholytic granules.

[0031] As a further optimization, in order to stir and break up the clumps of the litholytic and choleretic granules, the round tank is equipped with a stirrer, which includes:

[0051] The bottom of the cylindrical tank is connected to a hot air output device to provide hot air. The choleretic granules to be dried are fed into the top of the cylindrical tank. The hot air blows the choleretic granules up and down at the bottom of the cylindrical tank. The churning choleretic granules are more dispersed, which is conducive to uniform drying. The exhaust gas containing heat discharged from the top of the cylindrical tank enters the cavity jacket and is discharged to the outside. The residual heat of the exhaust gas inside the cavity jacket is transferred to the churning choleretic granules inside the cylindrical tank, further improving the drying uniformity. After drying, the weight of the choleretic granules decreases, and they can be blown up by the hot air and tumbled to the top. They then encounter a conical ring and slide outward along the inclined surface at the bottom of the conical ring to the outermost side. The hot air output device is intermittently powered. When the power is off, the hot air stops. The choleretic granules at the outermost bottom of the conical ring fall into the annular collection trough and are discharged through the discharge pipe. The above scheme does not require the choleretic granules to be spread out flat and has good drying uniformity, thus improving the production efficiency of choleretic granules.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0064] Please see Figure 1-6 This utility model provides a technical solution: a uniform drying device for preparing gallstone-expelling and choleretic granules, comprising:

[0065] Round can 1, with a hollow outer sleeve 2 fixedly fitted to its outer wall;

[0066] The lower end of the outer wall of the cavity jacket 2 is fixedly connected to a drain pipe 4 with a valve;

[0067] The exhaust gas outlet of the round tank 1 is fixedly connected to the upper end of the cavity outer sleeve 2 through a pipe;

[0068] The lower end of the hollow outer casing 2 is connected to the outside.

[0069] A hot air output device 5 is fixedly connected to the lower end of the round tank 1, which is intermittently powered.

[0070] A hot air distribution mechanism 8 is coaxially fixedly connected to the lower end of the inner cavity of the round tank 1;

[0071] The lower end of the round tank 1 is equipped with a discharge pipe 15;

[0072] An annular material collection trough 6 is coaxially fixedly assembled in the middle of the inner wall of the round tank 1, and the inner end of the discharge pipe 15 is connected to the lower end of the annular material collection trough 6.

[0073] A conical ring 7 is fixedly mounted coaxially at the upper end of the inner cavity of the round can 1, with its tip pointing downwards.

[0074] Specifically in this embodiment, the round tank 1 is a container for drying the stone-expelling and choleretic granules, and is provided with a feed inlet and a waste gas outlet. The dried stone-expelling and choleretic granules are discharged through the discharge pipe 15.

[0075] The cavity sleeve 2 is specifically a sleeve with an internal cavity, which is fitted and fixed to the outside of the round tank 1. The upper end of the cavity sleeve 2 is filled with the exhaust gas of the round tank 1, and the lower end is discharged with the exhaust gas. The residual heat in the exhaust gas is transferred to the round tank 1.

[0076] Furthermore, the lower end of the cylindrical tank 1 is connected to the hot air output device 5 to provide hot air. The choleretic granules to be dried are put into the upper end of the cylindrical tank 1. The hot air blows the choleretic granules up and down at the lower end of the cylindrical tank 1. The choleretic granules are more dispersed during the tumbling, which is conducive to being dried evenly. The exhaust gas containing heat discharged from the upper end of the cylindrical tank 1 enters the cavity jacket 2 and is discharged to the outside. The residual heat of the exhaust gas inside the cavity jacket 2 is transferred to the choleretic granules tumbling inside the cylindrical tank 1, which further improves the drying uniformity. After the choleretic granules are dried, their weight decreases and they can be blown up by the hot air and tumbled to the upper end. They then encounter the conical ring 7 and slide outward along the inclined surface at the lower end of the conical ring 7 to the outermost side. The hot air output device 5 is intermittently powered on. When the power is off, the hot air stops. The choleretic granules at the outermost side of the lower end of the conical ring 7 fall into the annular collection trough 6 and are discharged through the discharge pipe 15 after drying.

[0077] More specifically, the hot air distribution mechanism 8 disperses the hot air blown from the lower end of the round can 1, and blows the litholytic and choleretic granules at the lower end of the inner cavity of the round can 1 more evenly. At the same time, the conical ring 7 is set at a specific height, which is just enough to allow the dried litholytic and choleretic granules to slide outward along the inclined surface at the lower end of the conical ring 7 to the outermost side. The undried litholytic and choleretic granules, because of their greater weight, cannot reach the outermost side after sliding a distance along the inclined surface at the lower end of the conical ring 7 under the same wind force.

[0078] It is understood that this device is suitable for drying granular drugs, and in other embodiments it can also be used for drying other lightweight, small-sized granular materials besides pharmaceuticals.

[0079] In some embodiments, the cavity jacket 2 includes:

[0080] The outer body 21 has an annular cavity 22 coaxially formed on its inner wall;

[0081] Connecting pipes 23 are coiled around both the front and rear sides of the annular cavity 22;

[0082] The top surface of the annular cavity 22 extending from the upper end of the connecting pipe 23 is fixedly connected to the exhaust gas output end of the round tank 1 through a pipe.

[0083] The lower end of the connecting pipe 23 extends to the outside through the lower end of the side wall of the annular cavity 22.

[0084] Specifically, in this embodiment, the side wall of the outer casing 21 exposed to the outside is provided with a heat-insulating coating to reduce heat loss; the outer casing 21 and the connecting pipe 23 are made of heat-conducting metal material, and in this embodiment, aluminum alloy is used to better transfer heat to the round can 1;

[0085] Furthermore, the waste gas discharged from the round tank 1 with residual heat is divided into two parts through two pipelines and supplied to two connecting pipes 23 respectively. The middle parts of the two connecting pipes 23 are respectively coiled and arranged inside the annular cavity 22 on the front and back sides to release residual heat and make better use of the residual heat.

[0086] Understandably, the upper end of the connecting pipe 23 exposed to the outside, and the outer wall of the pipe connecting the connecting pipe 23 and the upper end of the cylindrical tank 1 are all provided with heat insulation coating to further reduce heat loss.

[0087] In some embodiments, the annular aggregate tank 6 includes:

[0088] An annular baffle 61 has a retaining edge at the lower edge of its outer annular surface;

[0089] The lower edge of the outer ring of the annular baffle 61 is fixedly connected to the inner wall of the round tank 1;

[0090] An annular baffle 61 and the inner wall of the cylindrical tank 1 form a material collection annular cavity 62;

[0091] Semi-annular guide plates 63 are fixedly assembled on both the front and rear sides of the lower end of the inner wall of the collecting ring cavity 62.

[0092] The upper end of the semi-annular guide plate 63 is provided with an inclined slope, and the upper slope of the semi-annular guide plate 63 extends inclinedly to the inner end of the discharge pipe 15.

[0093] Specifically, in this embodiment, the collecting ring cavity 62 is an annular receiving cavity formed by the annular baffle 61 and its lower edge baffle and the inner wall of the round tank 1, which collects the dried stone-expelling and choleretic granules that fall from above.

[0094] Furthermore, the slope of the upper end of the semi-annular guide plate 63 extends to the inner end of the discharge pipe 15, guiding the stone-discharging and choleretic particles collected in the collecting ring cavity 62 to the discharge pipe 15, and discharging the collected stone-discharging and choleretic particles.

[0095] Understandably, after the device is used, a small amount of stone-discharging and choleretic particles adhering to the bottom surface of the collecting ring cavity 62 can be vibrated and slid down along the upper slope of the semi-annular guide plate 63 by striking the outer wall of the vibrating tank 1 with appropriate force, and then discharged along the discharge pipe 15.

[0096] In some embodiments, the hot air distribution mechanism 8 includes:

[0097] Distributor 83 is coaxially located at the lower end of the inner cavity of the cylindrical tank 1;

[0098] A support rod 81 is fixedly connected between the outer wall of the distributor 83 and the lower end of the inner wall of the cylindrical tank 1.

[0099] The lower end of the distributor 83 is fixedly connected to a conical cover 82, with its larger end facing downwards and fitting against the inner wall of the round tank 1.

[0100] Specifically, in this embodiment, the distributor 83 is a circular plate with ventilation holes evenly opened on both the upper and lower sides;

[0101] Furthermore, the distributor 83 is fixed to the lower end of the inner wall of the cylindrical tank 1 by the support rod 81, and the lower end of the distributor 83 is guided by the fixed conical cover 82 to guide the hot air, so that the hot air is dispersed through the distributor 83 and continues to rise.

[0102] It is understandable that even if some gallstone-expelling and choleretic granules fall from the ventilation hole of the distributor 83, they can pass through the ventilation hole and return to the top of the distributor 83 during the intermittent blowing and tumbling of hot air.

[0103] In some embodiments, the cylindrical tank 1 is equipped with a stirrer 3, which includes:

[0104] The drive motor 31 is fixedly mounted on the middle of the top surface of the cylindrical tank 1;

[0105] The lower end of the drive motor 31 is fixedly connected to a round rod 32 that passes through the top surface of the round tank 1, and its lower end extends through the inner ring surface of the conical ring body 7 to the lower end of the round tank 1.

[0106] A stirring blade 33 is uniformly fixedly mounted on the lower end of the outer wall of the round rod 32;

[0107] The upper stirring blade 33 is located inside the annular aggregate tank 6.

[0108] Specifically, in this embodiment, the drive motor 31 is a servo motor;

[0109] Furthermore, the drive motor 31 is connected to an external power source to drive the round rod 32 and the stirring blade 33 thereon to rotate. The rotating stirring blade 33 is used to break up the clumps of gallstone-dissolving and choleretic granules blown by hot air.

[0110] It is understood that the shape of the stirring blade 33 is strip-shaped in this embodiment, but in other embodiments it can be fan-shaped or rod-shaped, etc., which can break up the clumps of gallstone-expelling and choleretic particles during rotation.

[0111] In some embodiments, a distribution plate is fixedly mounted on the inner wall of the cylindrical tank 1 between the hot air distribution mechanism 8 and the annular collection trough 6. In this embodiment, the distribution plate is specifically a mesh plate, which is used to further disperse the hot air. Similar to the distributor 83, the choleretic and stone-expelling particles that fall along the mesh of the mesh plate can pass through the mesh of the mesh plate and return to the top of the distribution plate during the intermittent blowing and tumbling of the hot air.

[0112] In some embodiments, the hot air output device 5 includes:

[0113] The electric heating cylinder 52 has a connecting bend 51 fixedly connected to one end, and a blower 53 fixedly connected to the other end.

[0114] The end of the connecting bend 51 is bent upwards and fixedly connected to the lower end of the round tank 1.

[0115] Specifically in this embodiment, the blower 53 and the electric heating cylinder 52 are respectively connected to an external power source. The blower 53 blows air into the electric heating cylinder 52. The electric heating cylinder 52 has sufficient length and the internal heat sources are relatively densely distributed, so that the passing air is heated into hot air. The hot air is supplied from the lower end of the round tank 1 along the connecting bend pipe 51.

[0116] In some embodiments, the heating cylinder 52 includes:

[0117] A cylindrical shell 521 has an electric heating tube 522 coaxially wound around its inner wall along its length.

[0118] The heating element 522 is connected to an external power source. The heating element 522, which is coiled along the inner wall of the heating tube, increases the heating effect on the passing air. The distance between the upper and lower coils of the heating element 522 is less than twice the outer diameter of the heating element 522. Each coil of the heating element 522 has multiple layers. The distribution of the coiled heating element 522 as a heat source within the heating cylinder 52 ensures density.

[0119] In some embodiments, support legs 9 are fixedly fitted on both the left and right sides of the lower end of the cavity jacket 2;

[0120] The lower ends of the support leg 9 and the hot air output device 5 are both in contact with the ground. The support leg 9 is used to provide stable support for the device and ensure that the device operates smoothly on the ground.

[0121] In some embodiments, the cylindrical container 1 includes:

[0122] The tank body 11 has an exhaust gas outlet pipe 12, a feed pipe 14 and a pressure relief valve 13 fixedly connected to its top edge.

[0123] The upper end of the exhaust gas outlet pipe 12 is fixedly connected to the upper end of the cavity outer sleeve 2 via a pipe;

[0124] A cap is screwed to the upper end of the feed pipe 14;

[0125] The discharge pipe 15 is fixedly connected to the lower end of the side wall of the tank body 11, and the discharge pipe 15 passes through the reserved through hole on the cavity outer sleeve 2.

[0126] Specifically in this embodiment, the tank 11 discharges waste gas containing residual heat through the waste gas output pipe 12; the choleretic and stone-dissolving granules to be dried are fed in through the feed pipe 14, and the cap at the top of the feed pipe 14 is screwed on to cover the feed after feeding.

[0127] Understandably, a sealing ring is provided between the outer wall of the discharge pipe 15 and the reserved through hole on the cavity jacket 2 to reduce the heat loss from this point; at the same time, when the exhaust pipe 12 or its connecting pipe is blocked and cannot exhaust normally, the pressure relief valve 13 can be used for emergency exhaust of the tank 11.

[0128] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
