Description

Technical Field

[0001] This utility model relates to the field of distillation apparatus technology, specifically to an energy-saving distillation apparatus for pharmaceutical and chemical applications. Background Technology

[0002] With social development and technological progress, the pharmaceutical industry has also developed rapidly. Medicines are substances or preparations for the prevention, treatment or diagnosis of human and animal diseases. In the pharmaceutical and chemical production process, pharmaceutical and chemical distillation equipment is often used to distill and extract pharmaceutical chemicals.

[0003] A search revealed existing technology (publication number: CN220026138U), which describes "a leak-proof pharmaceutical and chemical distillation apparatus, comprising a main body and an auxiliary body, wherein the auxiliary body is located at the upper end of the main body, and the main body includes a device body, a distillation tank, and a storage tank. The distillation tank is fixedly installed at the right end of the upper part of the device body, and the storage tank is fixedly installed at the upper part of the distillation tank. This leak-proof pharmaceutical and chemical distillation apparatus, through the installation of the main body, enables the device body to perform closed distillation operations when processing pharmaceutical and chemical materials, effectively preventing material leakage during the distillation process. The design of the feed pump ensures the sealing of the pharmaceutical and chemical raw material supply process, preventing leakage and thus improving the stability of the distillation operation of the device body, thereby ensuring the distillation accuracy of the pharmaceutical and chemical materials."

[0004] While existing pharmaceutical and chemical distillation equipment has achieved leak-proof and stable distillation, it still has some shortcomings: In use, the heating components of existing pharmaceutical and chemical distillation equipment are located outside the raw material and do not have deep contact with the raw material, resulting in a small contact area and poor heating efficiency. As a result, there is a deviation in energy saving effect. Secondly, the condenser cannot condense the steam transported by the pipeline, so the liquid needs to be condensed again and then pumped to the collection box, resulting in low overall production efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, an energy-saving distillation apparatus for pharmaceutical and chemical applications is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, an energy-saving distillation apparatus for pharmaceutical and chemical applications is provided, comprising: a distillation tank and a cooling device. The upper side of the distillation tank is equipped with a motor and a feed inlet, and the lower end of the motor is connected to a stirring shaft, with stirring blades connected to the outer side of the stirring shaft. The interior of the distillation tank is equipped with a conduit, and the outer wall of the conduit is connected to a heating rod. The cooling device is located outside the distillation tank and includes a water storage tank. The upper end of the water storage tank is connected to a water pump, the outlet end of the water pump is connected to a water inlet pipe, and the upper end of the water inlet pipe is connected to a condenser pipe. The outer wall of the condenser pipe is connected to a return water pipe. The interior of the condenser pipe is equipped with a gas guide pipe, the upper end of which is connected to the upper side wall of the distillation tank, and the lower end of the gas guide pipe is connected to a collection box.

[0007] Furthermore, the inner top wall of the distillation chamber is equipped with a temperature sensor, and the outer wall of the distillation chamber is equipped with a temperature controller and a control unit, and the temperature sensor is electrically connected to the temperature controller.

[0008] Furthermore, the conduit has a wire hole inside, and a power wire is installed inside the wire hole, and the power wire is electrically connected to the heating resistance wire in the heating rod.

[0009] Furthermore, the water pump has a suction pipe connected to its inlet end, and the suction pipe is inserted downward into the water storage tank.

[0010] Furthermore, the outer wall of the water storage tank is provided with heat dissipation holes, and a water distribution plate is provided inside the water storage tank. The water distribution plate is located above the heat dissipation holes, and the lower end of the return water pipe is connected to the water distribution plate.

[0011] Furthermore, the upper end of the condenser is connected to a first port, and the lower end of the condenser is provided with a second port, and the gas guide pipe passes through the condenser through the first port and the second port.

[0012] Furthermore, the outer wall of the condenser tube is provided with an outlet and an inlet, and the inlet pipe is connected to the inlet, the return pipe is connected to the outlet, and the outlet is located above the inlet.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. During use, pharmaceutical and chemical raw materials enter the distillation tank through the feed inlet, and are then stirred by the motor, stirring shaft and stirring blades. At the same time, they are heated by the heating rods. Since the heating rods are evenly arranged in layers in the distillation tank and are staggered with the stirring blades, the contact area with the raw materials is increased, the heating uniformity and efficiency are improved, and the evaporation temperature is quickly reached, thereby achieving energy saving.

[0015] 2. The steam in the distillation tank is discharged outward through the gas guide pipe, and then passes through the cooling device and condenser. The cooling device, which includes a water tank, water pump, suction pipe, inlet pipe, outlet pipe, and return pipe, circulates the cooling water inside the condenser, thereby cooling the hot steam inside the gas guide pipe and causing it to condense. The condensate flows down the inner wall of the gas guide pipe to the collection box, thus realizing the condensation operation in the steam flow pipeline, further improving the efficiency of the overall distillation operation.

[0021] Reference Figures 1 to 4As shown, this utility model provides an energy-saving distillation device for pharmaceutical and chemical applications, comprising: a distillation tank 1 and a cooling device 2. The upper side of the distillation tank 1 is provided with a motor 11 and a feed inlet 12, and the lower end of the motor 11 is connected to a stirring shaft 14, and the outer side of the stirring shaft 14 is connected to a stirring blade 15. The interior of the distillation tank 1 is provided with a conduit 16, and the outer wall of the conduit 16 is connected to a heating rod 17. The cooling device 2 is located on the outside of the distillation tank 1, and the cooling device 2 includes a water storage tank 21, and the upper end of the water storage tank 21 is connected to a water pump 24.

[0022] In this embodiment, the distillation tank 1, cooling device 2, condenser 3, and collection tank 4 constitute the main structure of the energy-saving distillation apparatus for pharmaceutical and chemical applications involved in this application.

[0023] Specifically, the heating rod 17 is symmetrically arranged about the stirring shaft 14, and the heating rod 17 and the stirring blade 15 are distributed in an interlocking manner in the horizontal direction, that is, the heating rod 17 and the stirring blade 15 (at a specific angle) are arranged vertically in sequence.

[0024] Specifically, the gas guide pipe 41 is designed as a bent pipe structure, and the section connected to the distillation tank 1 is inclined downwards. A one-way valve is provided at the connection between the gas guide pipe 41 and the distillation tank 1.

[0025] Specifically, the collection box 4 is equipped with a filter screen, and a collection container is located below the filter screen. The collection container can be taken out and put in by opening the box door on the outside of the collection box 4.

[0026] like Figure 1 and Figure 2 As shown, a temperature sensor 13 is provided on the inner top wall of the distillation chamber 1, and a temperature controller 5 and a controller 6 are provided on the outer wall of the distillation chamber 1. The temperature sensor 13 is electrically connected to the temperature controller 5. A wire hole 161 is opened inside the wire tube 16, and a power line 162 is provided inside the wire hole 161. The power line 162 is electrically connected to the heating resistance wire 171 in the heating rod 17.

[0027] Specifically, the conduit 16 is vertically installed inside the distillation tank 1, and the bottom of the conduit 16 is welded to the inner bottom wall of the distillation tank 1. The power cord 162 passes through the tank wall of the distillation tank 1 and is connected to the controller 6.

[0028] Specifically, the controller 6 is equipped with a PLC and an AC contactor to control the switching on and off of the power line 162. The switching signal comes from the temperature sensor 13 and is electrically connected to the controller 6 through the temperature controller 5.

[0029] Specifically, the heating rod 17 has a mineral insulating material on the inside and a metal shell on the outside, and the heating resistance wire 171 generates heat and conducts it outward after being energized.

[0030] like Figure 3 and Figure 4 As shown, the water pump 24 has a suction pipe 241 connected to its inlet end, and the suction pipe 241 is inserted downward into the water storage tank 21. The outer wall of the water storage tank 21 has heat dissipation holes 22. The inside of the water storage tank 21 has a water distribution plate 23, which is located above the heat dissipation holes 22. The lower end of the return water pipe 243 is connected to the water distribution plate 23. The upper end of the condenser pipe 3 is connected to a first pipe port 32, and the lower end of the condenser pipe 3 has a second pipe port 33. The air guide pipe 41 passes through the condenser pipe 3 through the first pipe port 32 and the second pipe port 33. The outer wall of the condenser pipe 3 has an outlet 31 and an inlet 34, and the inlet pipe 242 is connected to the inlet 34. The return water pipe 243 is connected to the outlet 31, and the outlet 31 is located above the inlet 34.

[0031] Specifically, the water distribution plate 23 has an inner cavity, and the return water pipe 243 is connected to the inner cavity. The bottom wall of the inner cavity has a porous structure to achieve the effect of downward spraying of return water. Then, in conjunction with the heat dissipation holes 22 on the outside, the return water is cooled.

[0032] It should be noted that the water distribution plate 23 is smaller than the internal size of the water storage tank 21, and there is a gap between it and the heat dissipation hole 22 to facilitate air circulation and heat dissipation.

[0033] In operation, pharmaceutical and chemical raw materials enter the distillation tank through the feed inlet, and are then stirred by the motor, stirring shaft, and stirring blades. Simultaneously, they are heated by heating rods. Because the heating rods are evenly layered within the distillation tank and staggered with the stirring blades, the contact area with the raw materials is increased, improving heating uniformity and efficiency, achieving rapid evaporation temperature and thus energy savings. Steam from the distillation tank is discharged outwards via a gas guide pipe, and then circulates through a cooling device and condenser. The cooling device, including a water tank, water pump, suction pipe, inlet pipe, outlet pipe, and return pipe, circulates cooling water within the condenser, cooling the hot steam inside the gas guide pipe and causing condensation. The resulting condensate flows downwards through the inner wall of the gas guide pipe to the collection tank, thus achieving condensation within the steam flow pipeline and further improving the overall efficiency of the distillation operation.

[0034] This utility model of an energy-saving distillation device for pharmaceutical and chemical applications effectively solves the problems mentioned in the background technology. It achieves rapid heating and distillation effects and rapid condensation effects based on existing energy-saving distillation device technology for pharmaceutical and chemical applications, saving distillation time and reducing the use of electrical equipment, thus having the advantages of energy saving and high efficiency.
