Description

Technical Field

[0001] The utility model relates to the technical field of dehydration devices, in particular to a dehydration device for producing triacetin. Background Art

[0002] A dehydration device is a device used to remove excess water from materials. Common dehydration devices include centrifugal dehydrators, belt dehydrators, filter presses, and presses. Centrifugal dehydrators use centrifugal force to separate water from solids in materials. They are widely used in chemical, pharmaceutical, food, mining, environmental protection and other industries. Belt dehydrators achieve dehydration through belt transportation and the filtering effect of filter belts. They are suitable for textiles, leather, papermaking, printing and dyeing, mining, building materials and other fields. Filter presses and presses remove water from materials by applying pressure.

[0003] The existing triacetin dehydration device has a slow dehydration speed during operation, resulting in a longer production cycle of triacetin, which will reduce the production efficiency of the entire production line. It also means that the equipment needs to work longer, thereby consuming more energy and increasing the energy consumption cost in the production process of triacetin. Utility Model Content

[0004] The utility model mainly provides a dehydration device for producing triacetin which can accelerate the dehydration speed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dehydration device for triacetin production, comprising a dehydration mechanism, a cooling mechanism is fixedly installed on the top of the dehydration mechanism; the dehydration mechanism comprises a reaction tank, a circular hole 1 is opened on the top of the reaction tank, a circular hole 2 is opened on the top of the reaction tank, a circular hole 3 is opened on the top of the reaction tank, a feed port is arranged on the top of the reaction tank, a motor is fixedly installed on the top of the reaction tank, a rotating shaft is fixedly installed on the output end of the motor, and the outer wall of the rotating shaft is movably inserted in the inner part of the circular hole 2, a group of stirring paddles are fixedly installed on the outer wall of the rotating shaft, and the bottom of the reaction tank is fixedly installed A group of supporting legs is provided, and a base is fixedly installed between the bottoms of the group of supporting legs. A discharge port is provided at the bottom of the reaction tank, and the user can pour the triacetin to be dehydrated into the reaction tank through the feed port. Then the dehydration device is started, and the internal triacetin is heated through the reaction tank to evaporate the internal water. At this time, the motor starts to start, driving the rotating shaft to rotate inside the second circular hole. When the rotating shaft rotates, it will drive a group of stirring paddles fixedly installed on the outer wall to rotate together, stirring the triacetin inside the reaction tank, increasing the heating area of ​​the triacetin, and making the triacetin evenly heated everywhere, thereby improving the dehydration effect of the device.

[0006] Preferably, a vacuum pump is fixedly installed on the top of the reaction tank, and the output end of the vacuum pump is fixedly connected to an air outlet pipe. After the vacuum pump is started, the air inside the reaction tank will be extracted.

[0007] Preferably, the input end of the vacuum pump is fixedly connected to an air inlet pipe, and the outer wall of the air inlet pipe is fixedly inserted into the inside of the circular hole three. The vacuum pump draws out the air inside the reaction tank through the air inlet pipe and discharges it through the air outlet pipe, so that a negative pressure is formed inside the reaction tank, the boiling point of the water inside the triacetin is reduced, and the energy consumption during dehydration is reduced.

[0008] Preferably, the cooling mechanism includes a delivery pipe, the output end of the delivery pipe is fixedly connected to a condenser, after the water inside the triacetin evaporates, the water vapor will enter the delivery pipe, and the delivery pipe will transport the water vapor forward to the inside of the condenser.

[0009] Preferably, a group of cooling fins are fixedly mounted on the outer wall of the condenser, and four fans are fixedly installed between the outer walls of the group of cooling fins. The cooling fins can fix the position of the condenser to prevent the condenser from deformation after long-term use, thereby extending the service life of the condenser. After the fans are started, external cold air will continuously pass through the cooling fins, thereby keeping the cooling fins at a lower temperature.

[0010] Preferably, a water tank is fixedly sleeved between the outer walls of a group of the heat dissipation fins, and the outer wall of the condenser is fixedly inserted into the water tank. The cooling water in the water tank can condense the water vapor inside the condenser, which is convenient for users to collect and process. The heat dissipation fins can keep the cooling water at a low temperature to avoid a reduction in cooling effect due to an increase in the cooling water temperature.

[0011] Preferably, the top of the base is fixedly connected to the bottom of the water tank, the inner wall of the circular hole 1 is fixedly inserted into the outer wall of the delivery pipe, the water vapor inside the reaction tank comes to the inside of the condenser through the delivery pipe, and is condensed under the action of cooling water. The device does not need to use running water for cooling, which not only reduces the waste of water resources, but also simplifies the device structure.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, under the action of the dehydration mechanism, when the reaction tank heats the triacetin inside, the motor will drive a group of stirring paddles to rotate through the rotating shaft after starting, thereby increasing the heating area of ​​the triacetin and increasing the evaporation rate of the internal water. At this time, the vacuum pump will extract the air inside the reaction tank, so that the internal air pressure of the reaction tank is reduced and the boiling point of the water is reduced. Through the above structure and method, the equipment can complete the dehydration task in a shorter time, thereby reducing energy consumption and energy use costs. Accelerating the dehydration speed can also shorten the production cycle and reduce the residence time of materials in the equipment, thereby increasing production.

[0014] 2. In the utility model, under the action of the cooling mechanism, the heat dissipation fins and the fan cooperate with each other, so that the cooling water inside the water tank can always maintain a low temperature, without the need to use running water for cooling, reducing the consumption of water resources, simplifying the structure of the equipment, and facilitating the workers to install and operate the equipment.

The motor 106 will drive the rotating shaft 107 to start rotating, and the rotating shaft 107 will drive a group of stirring paddles 108 to rotate together. When the group of stirring paddles 108 rotate, the internal triacetin is stirred to increase the evaporation rate of water.

Then the water vapor passes through the delivery pipe 201 to the inside of the condenser 202. The cooling water in the water tank 205 will condense the water vapor inside the condenser 202. A group of heat dissipation fins 203 will take out the heat inside the cooling water.
