[0003] When the existing paste making machine is in use, when the humidity in the air is high, that is, the water vapor content is large, the water vapor in the air is close to saturation. In the working environment of the paste making machine or inside the equipment, if there is an obvious temperature difference, such as the surface temperature of the equipment is low and the surrounding temperature is high, or the temperature inside the equipment drops rapidly while the external air temperature is relatively high, a temperature gradient will be formed. When the hot and humid air encounters the surface of an object with a lower temperature, the water vapor in the air will condense into liquid water on the surface, forming condensed water, and flow back into the paste making machine.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention uses a condensation component and an air intake component. Motor 2 in the air intake component is started to drive the fan blades to rotate. The fan blades move the evaporated water vapor upward and enter between the condensation plate and the conical shell.

When rotating, Motor 2 drives the linkage cylinder to rotate by setting a speed reduction structure.

The pressure plate descends and drives the lower spring to contract. The pressure plate drives the driving rope to tighten. The driving rope passes through the guide wheel 1 and the guide wheel 2 to pull the L rod. The L rod moves upward and drives the spring 1 to contract. At the same time, the L rod drives the plug to move, so that the plug no longer blocks the water outlet of the water outlet pipe, and water flows out of the water outlet pipe, thereby realizing the function of automatic drainage. After each use of the paste machine, the L rod is manually pulled upward to drain all the water in the water outlet pipe, thereby preventing acidic condensate from corroding the inner wall of the equipment.

[0036] In some specific embodiments, such as Figure 3 or Figure 4As shown, in order to collect the condensed water on the inner top of the top cover 3, the scraping assembly includes a linkage cylinder 301, an inner gear ring 303, a gear 2 304 and a guide groove plate 306.

Finally, the remaining condensed water will remain at the bottom of the V-shaped annular groove 2032, reducing the corrosion area of ​​the acidic condensed water on the insulation board 203.

[0038] In some specific embodiments, such as Figure 4 As shown, in order to facilitate the improvement of water vapor circulation, a plurality of air outlet holes 205 are circumferentially distributed on the upper end of the conical shell 204. The air outlet holes 205 on the conical shell 204 are all inclined downward. The air outlet holes 205 increase the air flow speed on the upper side of the mixing chamber 1.

A plurality of heat conducting rods (not marked in the figure) for heating the conical shell 204 are connected to the lower side of the conical shell 204. The conical shell 204 absorbs the heat inside the mixing chamber 1 through the heat conducting rods, so that the temperature inside the conical shell 204 is the same as the temperature inside the mixing chamber 1, thereby avoiding the large temperature difference between the conical shell 204 and the mixing chamber 1, which causes the condensed water droplets to flow back into the mixing chamber 1.

[0039] In some specific embodiments, such as Figure 4As shown, in order to increase the contact area between the condensation plate 202 and the water vapor, the inner annular surface of the condensation plate 202 is a wavy curved surface. The condensation plate 202 is a metal material with good thermal conductivity.

[0040] In some specific embodiments, such as Figure 5 As shown, in order to prevent the guide trough plate 306 from damaging the top wall of the top cover 3, the rear side wall of the guide trough plate 306 is higher than the front side wall, and a rubber scraper 3061 is provided on the rear side wall of the guide trough plate 306, and the top of the rubber scraper 3061 is in contact with the inner wall of the top cover 3, and the cleaned water droplets flow downward along the side wall of the rubber scraper 3061 into its groove, and the condensed water droplets flow downward along the groove of the guide trough plate 306 and enter the upper side of the insulation plate 203 for collection.

[0041] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0042] Lead powder, acid, water and other raw materials are put into the stirring bin 1 through the feed port 101, the stirring structure is started to stir the raw materials, the motor 103 is started to drive the driving shaft 104 to rotate, and the driving shaft 104 drives the stirring blade 105 to stir the raw materials. Steam is discharged during the stirring process, and part of the steam passes through the air outlet 205 into the space between the condensation plate 202 and the conical shell 204, and the motor 206 is started to drive the rotating shaft 207 and the fan blade 208 to rotate synchronously. The rotation of the fan blade 208 drives the evaporated water vapor to move upward and enter between the condensation plate 202 and the conical shell 204, thereby improving the condensation efficiency of the water vapor. The steam contacts the inner wall of the condensation plate 202 to generate condensed water, and the cold The condensed water flows to the top of the insulation board 203. While the rotating shaft 207 rotates, the teeth 305 drive the gear 2 304 to rotate. The inner gear ring 303 meshing with the gear 2 304 rotates, thereby driving the linkage cylinder 301 at the bottom to reduce the speed. The linkage cylinder 301 drives the guide groove plate 306 on the side to rotate. The top of the rubber scraper 3061 fits with the inner wall of the top cover 3. The cleaned water droplets flow downward along the side wall of the rubber scraper 3061 into its groove. The condensed water droplets flow downward along the groove of the guide groove plate 306 and enter the upper side of the insulation board 203 for collection, so as to prevent the condensed water on the top of the top cover 3 from falling into the inside of the mixing bin 1 from the air outlet 205 and affecting the quality of the paste.

[0043] After the equipment has been used for a long time, when the liquid level between the condensation plate 202 and the conical shell 204 rises to make the float 507 float, one end of the seesaw 502 rotates downward, the upper spring 503 extends, and one end of the seesaw 502 squeezes the pressure plate 504 during the rotation. The pressure plate 504 descends and drives the lower spring 505 to contract. The pressure plate 504 drives the driving rope 508 to tighten. The driving rope 508 passes through the guide wheel 1 509 and the guide wheel 2 607 to pull the L rod 604. The L rod 604 moves upward and drives the spring 1 605 to contract. At the same time, the L rod 604 drives the plug 603 to move, so that the plug 603 no longer blocks the water outlet of the water outlet pipe 601, and water flows out of the water outlet pipe 601 to realize the function of automatic drainage. After each use of the paste making machine, the L rod 604 is manually pulled upward to discharge all the water in the water outlet pipe 601 to prevent acidic condensed water from corroding the inner wall of the equipment.

[0044] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
