DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] See also Figure 1-Figure 6A concentrator for pharmaceutical production, comprising a concentrator body 1, a one-way discharge valve 2, a top cover 3, a feed pipe 4 and a motor 5. The bottom of the concentrator body 1 is provided with a one-way discharge valve 2 for discharging liquid medicine, the top of the concentrator body 1 is movably provided with a top cover 3, and the top of the top cover 3 is provided with a feed pipe 4 and a motor 5 for feeding liquid medicine to be concentrated.

[0030] In this embodiment, the concentrating body 1 includes a stirring mechanism 6, a concentrating inner cavity 7, a heating outer cavity 8, a water inlet pipe 9, a drain pipe 11 and an electric heating rod 12. The concentrating inner cavity 7 and the heating outer cavity 8 are provided inside the concentrating body 1. The concentrating inner cavity 7 is in contact with the heating outer cavity 8, and the diameter of the heating outer cavity 8 is larger than the concentrating inner cavity 7 and wraps the concentrating inner cavity 7. The stirring mechanism 6 is installed in the concentrating inner cavity 7, and the heating outer cavity 8 is installed on the heating outer cavity 8. The water inlet pipe 9 and the electric heating rod 12 are alternately arranged on the heating outer cavity 8. The electric heating rod 12 charges the battery and provides power for the electric heating wire. The battery on the electric heating rod 12 can be replaced. The bottom of the heating outer cavity 8 is connected to the drain pipe 11. The drain pipe 11 is a one-way valve drain pipe that can discharge the water flow in the heating outer cavity 8.

[0031] In this embodiment, water can be injected into the heating outer cavity 8 through the water inlet pipe 9. When the water flow in the heating outer cavity 8 is filled to a certain level, it stops. The water flow inside the heating outer cavity 8 is heated by the electric heating rod 12. The concentrated medicinal liquid in the concentration inner cavity 7 can be evenly heated by the heating outer cavity 8.

[0032] In this embodiment, the stirring mechanism 6 includes a rotating shaft 61, an internal stirring member 62, a connecting rod 63, a support rod 64, a reinforcing ring 65, a cleaning member 66 and a spiral rod 67. The top of the rotating shaft 61 is connected to the output end of the motor 5. The rotating shaft 61 is equipped with an internal stirring member 62 that can rotate with the rotating shaft 61. The bottom annular array of the rotating shaft 61 has a plurality of connecting rods 63. The other ends of the plurality of connecting rods 63 are connected to the support rod 64. The top of the support rod 64 is connected to the reinforcing ring 65. The plurality of support rods 64 are connected by the reinforcing ring 65 to increase the strength of the support rod 64. The plurality of support rods 64 are equipped with cleaning members 66 that can clean the inner wall of the concentration cavity 7 and spiral rods 67 that are installed between each two adjacent support rods 64 and can externally stir the medicine solution.

[0033] In this embodiment, the internal stirring member 62 includes a main shaft 21, stirring blades 22 and a bending portion 23. The main shaft 21 has a plurality of stirring blades 22 in a ring array that can stir the medicinal liquid. The stirring blades 22 are connected to the bending portion 23. The bending portion 23 has high shearing ability and large circulation ability. The axial diversion can be achieved through the inclination angle of the bending portion 23, which can make the mixing effect of the medicinal liquid more uniform and enable the medicinal liquid to be evenly heated.

[0034] In this embodiment, the cleaning member 66 is composed of a sleeve 31, cleaning cotton 32 and an arc-shaped protrusion 33. The sleeve 31 is located on the support rod 64. The side wall of the sleeve 31 is equipped with cleaning cotton 32 which can contact the side wall of the concentration cavity 7 when the support rod 64 rotates. There are a number of arc-shaped protrusions 33 in an equidistant array on the cleaning cotton 32. The several arc-shaped protrusions 33 can increase the roughness of the surface of the cleaning cotton 32, so that the cleaning effect of the cleaning cotton 32 on the concentration cavity 7 is better.

[0035] Working principle: When in use, the liquid medicine to be concentrated is poured into the concentration inner cavity 7 through the feed pipe 4 at the top, and then the heating outer cavity 8 is filled with water through the water inlet pipes 9 located on both sides of the concentrator body 1. When the water flow in the heating outer cavity 8 is filled to a certain extent, it stops, and then the electric heating wire on the electric heating rod 12 is driven to heat the water flow inside the heating outer cavity 8. By heating the outer cavity 8 to fully wrap the concentration inner cavity 7, the liquid medicine in the concentration inner cavity 7 can be evenly heated, thereby improving the concentration efficiency of the liquid medicine in the concentration inner cavity 7. At the same time, the driving motor 5 drives The rotating shaft 61 rotates, and the spiral rod 67 connected thereto can be driven to rotate together with the rotating shaft 61, and the liquid medicine is mixed by the spiral rod 67. When the rotating shaft 61 rotates, the main shaft 21 thereon can be driven to rotate together, and the stirring blades 22 installed in an array on the main shaft 21 can stir and mix the liquid medicine together. The external stirring of the liquid medicine by the spiral rod 67 and the internal stirring of the liquid medicine by the stirring blades 22 prevent the liquid medicine from being mixed unevenly. Under the heating action of the heating outer cavity 8, the liquid medicine can be evenly heated and concentrated, thereby improving the concentration effect of the liquid medicine.

[0036] As the rotating shaft 61 drives the spiral rod 67 to rotate, the cleaning member 66 on the support rod 64 will also be driven to rotate. Since the cleaning cotton 32 on the cleaning member 66 is in contact with the side wall of the concentration cavity 7, the residual liquid medicine on the side wall of the concentration cavity 7 can be scraped off during rotation to prevent the liquid medicine from remaining on the side wall and affecting the concentration effect.
