Description

Technical Field

[0001] The invention relates to a concentrating device, in particular to a concentrating device for preparing capsules. Background Art

[0002] A concentrator refers to equipment used in the concentration production process of traditional Chinese medicine, health products, natural condiments, food additives, food, chemical industry and other industries. In the preparation process of double-bone three-seed capsules, it is necessary to add dog bones, earthworms, angelica, vinegar frankincense and other medicinal materials into the extraction tank, add water and boil them, and then concentrate the extract into a clear paste. A common concentrator uses steam to heat the reactor and achieves the purpose of concentration by evaporating water.

[0003] However, when the existing concentrator is heated by steam, hot steam is easy to accumulate at the air inlet end of the heating chamber of the reactor, causing uneven heating of the reactor. When a serpentine tube is used for heating, the temperature of the steam at the tail of the serpentine tube will decrease, and heat absorption will occur after condensation, which is easy to cause heat loss. When the steam flow rate is controlled, faster steam flowing through the serpentine tube is not conducive to heat absorption. At the same time, the steam entry end often has higher heat. When the liquid inside the reactor evaporates to a certain liquid level, it will move away from the steam entry end, so that the liquid level is located in the lower temperature area at the bottom of the reactor, affecting the evaporation concentration efficiency.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention provides a first impeller and a second impeller. The second motor drives the second gear to move through the first gear, thereby driving the first impeller to rotate slowly, pushing the steam entering the heating inlet pipe to move, so that the steam flows to the heating chamber away from the end of the heating inlet pipe, so that the concentration tank is evenly heated. After a lot of steam accumulates, it moves downward. The steam will collide with the block downward under the push of the first impeller, so that the steam can fully contact the block.

The first impeller drives the second impeller to rotate through the supporting column. The blades of the second impeller are tilted, so as to blow air downward, so that the used steam quickly reaches the bottom end of the heating chamber and is discharged from the heating outlet pipe, so as to avoid heat loss caused by heat absorption after steam condensation.

[0026] 2. The present invention provides an electric push rod, a lifting plate and a piston ring.

The temperature of the wall of the concentration tank at the heated air inlet pipe is high, thereby increasing the evaporation rate and improving the concentration efficiency. The lifting plate pulls the second material pipe to rise, and the second material pipe slides with the first material pipe, so that the concentrated liquid is discharged through the first material pipe.

[0027] 3. The present invention provides a stirring rod, a spring and a telescopic tube. When the first motor rotates, the stirring rod is driven to rotate through the telescopic tube, so that the concentrated liquid inside the concentration tank is stirred, thereby promoting evaporation. When the lifting plate rises, the telescopic tube contracts and the spring is compressed. The inside of the telescopic tube is sealed with a sliding sealing ring to prevent the concentrated liquid from entering the telescopic tube. The gas inside the telescopic tube is discharged from the shaft end of the first motor.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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] See also Figure 1-7, the present invention provides a technical solution of a concentrating device for preparing capsules:

[0038] according to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a concentrating device for preparing capsules comprises a concentrating tank 1, the inner wall of which is provided with a heating chamber 9, a heating air inlet pipe 2 and a heating air outlet pipe 4 for communicating with the heating chamber 9 are installed on the concentrating tank 1, an evaporation discharge pipe 3 for communicating with the interior is installed on the top of the concentrating tank 1, a discharge mechanism 5 is connected to the bottom of the concentrating tank 1, a control mechanism 8 for controlling the movement of steam is connected to the concentrating tank 1, the control mechanism 8 comprises a second gear 83, the top of the heating chamber 9 of the concentrating tank 1 is rotatably connected with the second gear 83, a driving assembly for driving the second gear 83 to rotate is connected to the concentrating tank 1, a first impeller 84 is installed at the bottom end of the second gear 83, a support column 86 is installed at the bottom end of the first impeller 84, a second impeller 85 is installed at the bottom end of the support column 86, and a plurality of blocks 87 are installed on the concentrating tank 1 located in the heating chamber 9.

[0039] The driving assembly includes a second motor 81 , which is mounted on the concentration tank 1 , and a first gear 82 meshing with a second gear 83 is mounted on the output end of the second motor 81 , thereby driving the first impeller 84 and the second impeller 85 to rotate.

[0040] The heating air inlet pipe 2 is located at the upper part of the heating chamber 9 of the concentration tank 1. The blades of the first impeller 84 are vertical. The first impeller 84 is flush with the heating air inlet pipe 2, so as to facilitate pushing the hot steam to the end of the heating chamber 9 away from the heating air inlet pipe 2, so that the concentration tank 1 is evenly heated.

[0041] The blades of the second impeller 85 are inclined, and the second impeller 85 is close to the bottom end of the concentration tank 1, so as to facilitate the discharge of the used steam.

[0042] The plurality of blocks 87 are arranged in a ring matrix, and the blocks 87 are located between the first impeller 84 and the second impeller 85, so as to facilitate the impact of the steam and thus facilitate the full release of the heat of the steam.

[0043] according to Figure 1 , Figure 2 and Figure 3As shown, a concentrating device for preparing capsules, a lifting mechanism 6 for lifting the liquid level inside the concentrating tank 1 is connected to the concentrating tank 1, the lifting mechanism 6 includes a lifting plate 62, the lifting plate 62 is installed inside the concentrating tank 1, the edge of the lifting plate 62 is installed with a piston ring 63 that seals and slides with the inner wall of the concentrating tank 1, an electric push rod 61 for controlling the movement of the lifting plate 62 is installed on the concentrating tank 1, and a stirring mechanism 7 is connected to the concentrating tank 1, so as to facilitate lifting the liquid level of the concentrated liquid and make the concentrated liquid close to the heating inlet pipe 2, thereby improving the heating efficiency. In the prescription and production process of Shuanggu Sanzi Capsule, after the extracts of medicinal materials such as earthworm, angelica, vinegar frankincense, vinegar myrrh, melon seeds, cucumber seeds, leek seeds, calcined natural copper, astragalus, bone-healing rhubarb, etc. are concentrated to a certain degree, the medicine liquid will become viscous, and a higher temperature is required to evaporate the water. The viscous medicine liquid will settle to the bottom along with the drug particles, so that when the liquid level is raised, the position of the viscous medicine liquid will rise, so that it is close to the air intake pipe 2, which is more easily heated and the heating efficiency is improved.

[0044] The discharge mechanism 5 includes a second material pipe 52, and a lifting plate 62 is installed with the second material pipe 52 penetrating therethrough. The second material pipe 52 slides through the bottom end of the concentration tank 1, and the concentration tank 1 is located at the bottom end of the second material pipe 52 and is installed with a first material pipe 51 that is slidably sealed with the second material pipe 52, thereby facilitating the discharge of the concentrated liquid without affecting the movement of the lifting plate 62.

[0045] according to Figure 1 , Figure 2 and Figure 3 As shown, a concentrating device for preparing capsules, the stirring mechanism 7 includes a first motor 71, the first motor 71 is installed on the concentrating tank 1, the output end of the first motor 71 extends into the interior of the concentrating tank 1 and is installed with a telescopic tube 72, and a stirring rod 74 is installed on the telescopic tube 72, so as to facilitate the stirring of the concentrated liquid. When the lifting plate 62 moves, it can still work and increase the stirring effect. In the above-mentioned double-bone three-son capsule prescription and production process, the viscous medicine liquid will settle to the bottom along with the medicine particles. After the liquid level of the concentrated liquid is raised, the telescopic tube 72 slides, which can make the bottom stirring rods 74 close to each other, reduce the inertial stagnation area of ​​the medicine liquid, and thus increase the stirring effect during the stirring process.

[0046] A spring 73 for pushing the extension is installed inside the telescopic tube 72, and the bottom end of the telescopic tube 72 is in active contact with the lifting plate 62, so that the telescopic tube 72 automatically returns to its original position when the lifting plate 62 is reset.

[0047] The telescopic tube 72 is composed of multiple sections, and a sealing ring for sliding sealing is installed between each section of the telescopic tube 72. The top end of the telescopic tube 72 is connected to the outside through the rotating shaft of the first motor 71, thereby ensuring the normal sliding of the telescopic tube 72 and preventing the concentrated liquid from entering.

[0048] During specific use, the heating inlet pipe 2 is connected to the heating steam, and the heating outlet pipe 4 is used to discharge the heating steam and water. The water vapor evaporated in the concentrating tank 1 is discharged through the evaporation outlet pipe 3. An external condenser can be connected here. The extracts of medicinal materials such as earthworm, angelica, vinegar frankincense, vinegar myrrh, melon seeds, cucumber seeds, leek seeds, calcined natural copper, astragalus, drynaria, rhubarb, etc. in the prescription of Shuanggu Sanzi Capsule are poured into the concentrating tank 1, the concentrating tank 1 is closed, and steam is connected. The steam flows into the heating inlet pipe 2 and enters the heating chamber 9 to heat the concentrating tank 1. The second motor 81 is started. The second motor 81 drives the second gear 83 to move through the first gear 82, thereby driving the first impeller 84 to rotate slowly, pushing the steam entering the heating inlet pipe 2 to move, so that the steam flows to the heating chamber 9 away from the end of the heating inlet pipe 2, so that the concentrating tank 1 is evenly heated.

[0049] When a lot of steam accumulates, it moves downward. Under the push of the first impeller 84, the steam will collide with the block 87 downward, so that the steam can fully contact the block 87. The block 87 is used to absorb heat to ensure that the heat of the steam is fully utilized. The steam moves downward along the gap between the blocks 87. The first impeller 84 drives the second impeller 85 to rotate through the support column 86. The blades of the second impeller 85 are tilted, thereby blowing air downward, so that the used steam quickly reaches the inside of the heating chamber 9 and is discharged from the heating outlet pipe 4, avoiding heat loss caused by heat absorption after steam condensation.

[0050] When the temperature of the liquid inside the concentration tank 1 rises, the excess water will be evaporated and discharged from the evaporation discharge pipe 3. When the liquid level inside the concentration tank 1 drops, the electric push rod 61 is started. The electric push rod 61 pushes the lifting plate 62 to move upward. The piston ring 63 plays a sealing role, thereby pushing the concentrated liquid to move upward and close to the position of the heating intake pipe 2. The wall temperature of the concentration tank 1 at the heating intake pipe 2 is high, thereby increasing the evaporation speed and improving the concentration efficiency. The lifting plate 62 pulls the second material pipe 52 upward, and the second material pipe 52 slides with the first material pipe 51, so that the concentrated liquid is discharged through the first material pipe 51.

[0051] During the evaporation and concentration process, the first motor 71 is started and rotated, thereby driving the stirring rod 74 to rotate through the telescopic tube 72, thereby stirring the concentrated liquid inside the concentration tank 1, thereby promoting evaporation. When the lifting plate 62 rises, the telescopic tube 72 contracts and the spring 73 is compressed. The inside of the telescopic tube 72 is sealed with a sliding sealing ring to prevent the concentrated liquid from entering the telescopic tube 72. The gas inside the telescopic tube 72 is discharged from the axial end of the first motor 71. The spring 73 can drive the telescopic tube 72 to slide and extend when the lifting plate 62 descends, thereby ensuring the normal operation of the stirring rod 74.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
