[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 a significant 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.

A scraping assembly is provided on the rotating shaft 207.

[0034] In some specific embodiments, such as Figure 1 or Figure 4 As shown, in order to facilitate uniform stirring of the materials inside the stirring bin 1, the stirring structure includes a driving shaft 104 and stirring blades 105.

[0035] In some specific embodiments, such as Figure 6 or Figure 7As shown, in order to facilitate the automatic discharge of condensed water between the condensation plate 202 and the conical shell 204, the automatic drainage assembly includes a shell 5, which is detachably connected to the inside of the storage tank by a screw, and a fixed shaft 501 is installed on the inner rear wall of the shell 5, and a rocker 502 is rotatably connected to the outer side of the fixed shaft 501, and the rocker 502 can rotate around the fixed shaft 501. One end of the rocker 502 is fixedly connected to a pull rope 506, and the pull rope 506 passes through the side wall of the shell 5, and the end is fixedly connected to the float 507.

The T-block fixedly connected to the pressure plate 504 can slide up and down along the T-slot on the inner wall of the shell 5, and a rotating guide wheel 509 is installed on the inner top wall of the shell 5. The outer side of the water outlet pipe 601 is fixedly connected with a fixed frame 602, and an L-shaped L rod 604 is installed on the top wall of the fixed frame 602. The L rod 604 can move upward. 606 is fixed to the top of the fixed frame 602, and the top of the fixed frame 606 is rotatably connected to the guide wheel 2 607, and the guide wheel 2 607 is aligned with the L rod 604. The spring 1 605, the guide wheel 2 607, the guide wheel 1 509 and the pressure plate 504 are connected by a drive rope 508. 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 rocker 502 rotates downward, the upper spring 503 extends, and the rocker One end of 502 squeezes the pressure plate 504 during the rotation, and the pressure plate 504 descends, driving the lower spring 505 to contract, and the pressure plate 504 drives the driving rope 508 to tighten.

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, realizing the function of automatic drainage. After each use of the paste mixing machine, manually pull the L rod 604 upward to drain all the water inside the water outlet pipe 601 to prevent 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 facilitate the collection of condensed water on the 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. The linkage cylinder 301 passes through the top of the top cover 3 and is rotatably connected to the top cover 3. A cavity is provided in the middle of the linkage cylinder 301, and the rotating shaft 207 is rotatably connected to the inside of the linkage cylinder 301.

The guide groove plate 306 is fixedly connected to the side of the linkage cylinder 301 and cooperates with the top cover 3. The teeth 305, gear 2 304 and the inner gear ring 303 cooperate with each other to reduce the rotation speed of the linkage cylinder 301. A guide groove plate 306 is provided on the linkage cylinder 301, and the guide groove plate 306 is used to clean and collect condensed water on the top cover 3.

[0037] In some specific embodiments, such as Figure 8 As shown, in order to increase the service life of the insulation board 203, slopes 2031 are circumferentially provided on both sides of the top of the insulation board 203, and a V-shaped ring groove 2032 is provided between the two slopes 2031. The bottom end of the V-shaped ring groove 2032 is connected to the water outlet groove 6. Due to the characteristics of the acidic substances contained in the battery, the condensed water after the steam condenses is acidic and corrosive. When the condensed water is about to be discharged, the acidic condensed water flows along the slope 2031 to the V-shaped ring groove 2032, and the condensed water is discharged from the water outlet groove 6 from the V-shaped ring groove 2032. The remaining condensed water will remain at the bottom of the V-shaped ring 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. The outer side of each air outlet hole 205 is fixed with a raised waterproof cylinder to prevent the water condensed on the outer side of the air outlet hole 205 from flowing back into the mixing chamber 1 from the air outlet hole 205. The lower side of the conical shell 204 is connected with a plurality of heat-conducting rods (not marked in the figure) for heating it. 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 inside of 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 made of a metal material with good thermal conductivity. The curved surface of the condensation plate 202 increases the contact area with the steam and improves the condensation speed of the water vapor.

[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. 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 into the upper side of the insulation plate 203 for collection.

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

[0042] Raw materials such as lead powder, acid and water are put into the mixing bin 1 through the feed port 101, the mixing structure is started to mix the raw materials, the starting motor 103 drives the driving shaft 104 to rotate, and the driving shaft 104 drives the mixing blades 105 to mix the raw materials. Steam is discharged during the mixing 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 starting motor 206 drives the rotating shaft 207 and the fan blades 208 to rotate synchronously. The rotation of the fan blades 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 produce condensed water, and the cold The condensed water flows to the top of the heat insulation plate 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 into the upper side of the heat insulation plate 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 chamber 1 from the air outlet 205, 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 the point where the float 507 floats, 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, driving the lower spring 505 to contract, and 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, driving 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, realizing the function of automatic drainage. After each use of the paste mixing machine, manually pull the L rod 604 upward to drain all the water in the water outlet pipe 601 to prevent acidic condensate from corroding the inner wall of the equipment.

[0044] The above describes several embodiments of the present invention in detail, but the embodiments of the present invention are not limited to these and should not 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.
