Technical Field
[0001] This utility model relates to the field of integrated evaporation and drying technology, specifically an energy-saving integrated evaporation and drying device. Background Technology
[0002] An integrated evaporation and drying unit is a material handling device that integrates the evaporation and drying processes of a material into the same equipment or system to achieve high efficiency and energy saving. It is commonly used in industries such as chemical, food, pharmaceutical, and environmental protection. It can concentrate solutions, suspensions, emulsions, etc. The concentrated liquid enters the drying unit, where moisture is further removed through hot air flow, heat conduction, or radiation, ultimately forming dry solid particles and powder.
[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, uneven mixing of materials can lead to significant differences in material thickness and humidity in different areas. At the same time, the evaporation rate of moisture in the material is inconsistent, causing some areas to evaporate moisture quickly and form scorch, while other areas still have a lot of moisture remaining. This makes it impossible to heat the material evenly and accelerate the evaporation of moisture in the material. As a result, the product moisture content does not meet the standards, and it may even fail to pass quality inspection due to uneven quality.
[0004] To address the aforementioned problems, the inventors propose an energy-saving integrated evaporation and drying device. Utility Model Content

The heat lamps on the inner wall of the drying chamber will emit heat to further maintain the temperature inside the chamber and reduce heat loss. The heating blocks and heating wires on the inner wall of the chamber directly heat the material.

[0011] As a preferred technical solution of this application, the upper part of the drying box is provided with two exhaust pipes.
[0012] Through the above technical solution, the water vapor generated by the evaporation of the material will be discharged through the two exhaust pipes at the top of the drying chamber, so as to avoid excessive water vapor in the chamber affecting the drying efficiency, and at the same time maintain the stable air pressure in the chamber.
[0013] As a preferred technical solution of this application, the roller and belt are located inside the protective housing.
[0014] The above technical solution can protect the rollers and belts.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example: Figure 1-5As shown, this utility model provides an energy-saving integrated evaporation and drying device, including a drying box 1, two exhaust pipes 5 connected to the upper part of the drying box 1, a box body 2 fixedly connected to the lower inner wall of the drying box 1, a drain pipe 6 connected to the lower part of the box body 2, a valve 7 provided on the outer surface of the drain pipe 6, an evaporation device 3 provided inside the drying box 1, and a mixing device 4 provided inside the box body 2.
[0029] The mixing device 4 includes a protective shell 41. The top surface of the protective shell 41 is fixedly connected to the drying chamber 1. A plurality of rectangular arrayed rotating shafts 42 are movably passed through the lower inner wall of the protective shell 41. The rotating shafts 42 pass through the drying chamber 1 and extend into the chamber body 2. A support plate 43 is fixedly connected to the bottom surface of the protective shell 41. A motor 44 is fixedly connected to the lower inner wall of the support plate 43. The output end of the motor 44 extends into the protective shell 41 and is fixedly connected to one of the rotating shafts 42. A roller 45 is fixedly sleeved on the lower part of the rotating shaft 42. A belt 46 is sleeved between the rollers 45. The rollers 45 and the belt 46 are located inside the protective shell 41. A through groove 47 is opened on the outer surface of the rollers 45. The outer surface of the belt 46 is in contact with the inner wall of the through groove 47. A plurality of propellers 48 are fixedly sleeved on the outer surface of the rotating shaft 42. A baffle 49 is fixedly connected to the upper part of the chamber body 2. The top end of the rotating shaft 42 is rotatably connected to the baffle 49.
[0030] The propellers 48, which are fixedly sleeved on the outer surface of each rotating shaft 42, will rotate as the rotating shaft 42 passes through the drying box 1 and extends into the box 2. The rotation of the propellers 48 can stir the material in the box 2, preparing it for subsequent evaporation and drying, and can effectively make the material more uniformly mixed.
[0031] The evaporation device 3 includes symmetrically distributed warm air blowers 31. The output end of the warm air blower 31 is fixedly connected to a connecting pipe 32, which is connected to the drying chamber 1. Multiple heat lamps 33 are fixedly connected to the upper inner wall of the drying chamber 1. Multiple heating blocks 34 arranged in a rectangular array are fixedly connected to the inner wall of the chamber 2. Heating wires 35 are fixedly connected between adjacent heating blocks 34.
[0032] The heating blocks 34 and heating wires 35 on the inner wall of the box 2 directly heat the material. The heating blocks 34 are arranged in a rectangular array, and the heating wires 35 are connected to adjacent heating blocks 34, which can effectively make the material heat evenly and accelerate the evaporation of moisture in the material.
[0033] The working principle of the energy-saving integrated evaporation and drying device in this embodiment is as follows: When the motor 44 starts, its output end drives the shaft 42 connected to it to rotate. The roller 45 at the bottom of the shaft 42 rotates accordingly. Since the outer surface of the roller 45 has a through groove 47 and the outer surface of the belt 46 is in contact with the inner wall of the through groove 47, the other shafts 42 will also rotate synchronously through the belt 46. The roller 45 and the belt 46 are inside the protective shell 41, which can effectively prevent the material from entering the transmission area and ensure the stability of the transmission. The propellers 48 fixedly sleeved on the outer surface of each shaft 42 will rotate as the shaft 42 passes through the drying box 1 and extends into the box 2. The rotation of the propellers 48 can stir the material in the box 2, preparing for subsequent evaporation and drying, thereby achieving the purpose of effectively mixing the material more evenly.
[0034] After the heater 31 is started, the generated hot air is delivered to the drying chamber 1 through the connecting pipe 32 to heat the air inside the chamber and create a hot air environment. The heat lamp 33 on the inner wall of the drying chamber 1 will emit heat to further maintain the temperature inside the chamber and reduce heat loss. The heating blocks 34 and heating wires 35 on the inner wall of the chamber 2 directly heat the material. The heating blocks 34 are distributed in a rectangular array, and the heating wires 35 are connected to adjacent heating blocks 34, thereby achieving the purpose of effectively heating the material evenly and accelerating the evaporation of moisture in the material.
[0035] The water vapor generated by the evaporation of the material will be discharged through the two exhaust pipes 5 at the top of the drying chamber 1 to avoid excessive water vapor in the chamber affecting the drying efficiency, while maintaining stable air pressure inside the chamber.
