Description

Technical Field

[0001] The utility model relates to the technical field of water-based resin production, in particular to a vacuum generating device for water-based resin production. Background Art

[0002] Water-based resin is a new type of resin system that uses water as the dispersion medium. It has the advantages of environmental protection and safety. It is widely used in oil exploration and development, coatings, water treatment, papermaking, textiles, food, daily chemicals and other fields.

[0003] In the prior art, a vacuum evaporator is often used to evaporate and remove water from the resin when producing water-based resins. However, in the prior art, after the solvent enters the evaporation tank, all the solvents gather together, and the subsequent evaporation and removal of the solvents are not efficient. Therefore, in order to solve this problem, an improved vacuum generating device for water-based resin production is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a vacuum generating device for producing water-based resins to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum generating device for producing water-based resin, comprising an evaporator, wherein an evaporation mechanism for improving evaporation efficiency is arranged inside the evaporator, wherein the evaporation mechanism comprises a rotating distribution disk, a scraper, a feed pipe, a steam pipe, an interlayer, and a heating pipe, wherein a rotating distribution disk is movably arranged in the middle part of the inner side of the evaporator through a rotating shaft, a plurality of scrapers are evenly fixedly arranged on the outer surface of the lower end of the rotating distribution disk, a feed pipe is fixedly arranged on one side of the evaporator surface, a steam pipe is fixedly arranged on the end of the evaporator surface away from the feed pipe, an interlayer is opened on the inner side wall of the evaporator, and a heating pipe is fixedly arranged inside the interlayer.

[0006] Preferably, an electric motor is fixedly provided in the middle of the upper end of the evaporator, and the output shaft end of the electric motor is transmission-connected to the rotating shaft where the rotating distribution plate is located through a coupling, and the rotating distribution device can be driven to rotate by the electric motor, so that the material entering the evaporator through the feed pipe will first enter the upper end of the rotating distribution device, and then the rotating distribution device generates centrifugal force through rotation, so that the material can be thrown on the inner side wall of the evaporator and flow downward under the action of gravity. At this time, under the rotation of the scraper, these materials can flow downward while being spread and adhered to the inner side wall of the evaporator, so as to be continuously and evenly distributed, so that they can fully contact the inner side wall of the evaporator. At this time, the heating tube in the interlayer can quickly evaporate the material.

[0007] Preferably, a water separator is fixedly provided at one end of the steam pipe away from the evaporator, through which the azeotropic products (water and solvent) evaporated from the evaporator can be separated in the water separator after condensation. Since condensation and water separation and dehydration are mature technologies in the prior art and are not the protection points of this application document, this application document will no longer introduce the internal structure of the water separator in detail.

[0008] Preferably, a vacuum tube is fixedly provided on one side of the upper end of the evaporator, a vacuum pump is fixedly provided on the upper end of the vacuum tube, and a pressure gauge is fixedly provided on the surface of the vacuum tube. The air inside the evaporator can be extracted by the vacuum pump, thereby improving the subsequent processing quality of the material.

[0009] Preferably, a discharge pipe is fixedly provided on one side of the lower end of the evaporator, and residual liquid in the evaporator can be discharged through the discharge pipe.

[0010] Preferably, a control valve is provided between the discharge pipe, the feed pipe, the steam pipe, the vacuum pipe and the evaporator, and the control valve can be used to control whether the discharge pipe, the feed pipe, the steam pipe and the vacuum pipe are in conduction and working.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. During evaporation, the utility model can drive the scraper to rotate through the motor, so that the material can be evenly spread on the inner side wall of the evaporator. In this way, only a thin layer of material is evaporated each time, which can greatly improve the evaporation efficiency, realize the rapid evaporation, concentration and separation of the material, and improve the desolventizing efficiency; in addition, the material is evenly heated in the equipment and evaporates quickly and the residence time is short, which can effectively maintain the quality of the product.

[0020] See also Figure 1-5 The utility model provides a technical solution: a vacuum generating device for producing water-based resin, comprising an evaporator 1, wherein an evaporation mechanism for improving evaporation efficiency is arranged inside the evaporator 1, wherein the evaporation mechanism comprises a rotating distribution disk 2, a scraper 3, a feed pipe 4, a steam pipe 5, an interlayer 6, and a heating pipe 7. A rotating distribution disk 2 is movably arranged at the middle part of the inner side of the evaporator 1 through a rotating shaft, and a plurality of scrapers 3 are evenly fixedly arranged on the outer surface of the lower end of the rotating distribution disk 2. A feed pipe 4 is fixedly arranged on one side of the surface of the evaporator 1, and a steam pipe 5 is fixedly arranged on the end of the surface of the evaporator 1 away from the feed pipe 4. An interlayer 6 is opened on the inner side wall of the evaporator 1, and a heating pipe 7 is fixedly arranged inside the interlayer 6.

[0021] A motor 8 is fixedly arranged in the middle of the upper end of the evaporator 1, and the output shaft end of the motor 8 is transmission-connected to the rotating shaft of the rotating distribution plate 2 through a coupling, and the rotating distribution plate can be driven to rotate by the motor 8, so that the material entering the evaporator 1 through the feed pipe 4 will first enter the upper end of the rotating distribution plate, and then the rotating distribution plate generates centrifugal force through rotation, so that the material can be thrown on the inner side wall of the evaporator 1, and flow downward under the action of gravity. At this time, under the rotation of the scraper 3, these materials can flow downward while being spread and evenly distributed on the inner side wall of the evaporator 1, so that they can fully contact the inner side wall of the evaporator 1. At this time, the heating tube 7 in the interlayer 6 can quickly evaporate the material;

[0022] A water separator 9 is fixedly provided at one end of the steam pipe 5 away from the evaporator 1, and the azeotropic products (water and solvent) evaporated from the evaporator 1 can be separated in the water separator 9 after condensation and condensation through the water separator 9. Since condensation and water separation and dehydration are mature technologies in the prior art and are not the protection points of this application document, this application document will not introduce the internal structure of this water separator 9 in detail.

[0023] A vacuum tube 10 is fixedly arranged on one side of the upper end of the evaporator 1, a vacuum pump 11 is fixedly arranged on the upper end of the vacuum tube 10, and a pressure gauge 12 is fixedly arranged on the surface of the vacuum tube 10.

The control valve 14 can be used to control whether the discharge pipe 13, the feed pipe 4, the steam pipe 5 and the vacuum pipe 10 are connected and working.

[0026] Working principle: When using this device, the material to be evaporated is injected into the evaporator 1 through the feed pipe 4.
