[0002] Wet strength agents are mainly used in the papermaking industry.

There are many manufacturers, most of which are small-scale, but the quality of their products is good. In the production process of wet strength agent, it needs to be dehydrated and purified, which requires a dehydration equipment for wet strength agent reactor.

[0003] For example, the dehydration equipment for a wet strength agent reactor, published with the announcement number "CN213669241U," evenly stirs the material by driving the connecting shaft to swing the liquid balancing plate. The dehumidification pump is activated to draw moisture into the dehumidification cylinder through the air inlet flange, where the activated carbon absorbs the water vapor. This device is rationally designed and easy to use, achieving uniform mixing of the material and, consequently, uniform heating, resulting in excellent dehydration. However, the heating wire is located at the lower end of the reactor, prioritizing heat transfer to the wet strength agent at the bottom before heating the upper end. Furthermore, the electrical slider and connector are used to drive the connecting shaft to move left and right for stirring. This reciprocating stirring frequency is low and the heating speed is slow, thus reducing overall work efficiency. Utility Model Content

[0027] Working principle:

[0028] Wet strength agent dehydration and heating work:

[0029] When the wet strength agent needs to be dehydrated, the top cover at the upper end of the reactor 3 is opened, the wet strength agent is poured into the reactor 3, and the top cover is closed. The external power supply of the multiple heating rods 103 is connected, and the heating rods 103 are started to energize the internal heating wires to generate heat, which is transferred to the heating rods 103 to heat the heating rods 103, thereby heating the air near the air inlet of the air pump 101. At the same time, the external power supply of the air pump 101 is connected, and the air pump 101 is started to transport the hot air near the air inlet into the pipe 105. The hot air is transported through the pipe 105 into the cross pipe 204 and ejected from the multiple openings thereof to preheat the wet strength agent in the reactor 3. During this process, the ejected gas will flow toward the upper end of the reactor 3, allowing the filter 104 to take in air. At the same time, the external power supply of the heating plate 8 is connected, and the heating plate 8 is started to energize the internal heating wires to generate heat, which is transferred to the heating plate 8 to heat the heating plate 8. The heated heating plate 8 transfers the heat to the lower end of the reactor 3, thereby heating the wet strength agent therein.

[0030] Wet strength agent dehydration and mixing work:

[0031] While the wet strength agent is being heated, the external power supply of the motor 201 is turned on. The motor 201 starts and drives the first gear 202 to rotate in the housing 4 and the reactor 3 through the bearings. The rotation of the first gear 202 drives the second gear 203 to rotate. The rotation of the second gear 203 drives the cross tube 204 to rotate in the reactor 3 through the sealed bearing. During this process, the cross tube 204 can rotate in the pipeline 105 through the sealed bearing. The rotation of the cross tube 204 drives the multiple blades 205 to rotate synchronously to stir the wet strength agent in the reactor 3 so that it is evenly heated and dehydrated. This movement can dehydrate the wet strength agent. The steam generated in this process will be output from the straight pipe 5 to an external container containing activated carbon, and the activated carbon will adsorb and degrade the steam. When the dehydration of the wet strength agent is completed, the air pump 101 and the motor 201 stop working, and the external material box is placed under the water outlet 7. The valve installed in the middle of the water outlet 7 is opened for discharge and collection.

[0032] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
