Description

Technical Field

[0001] The utility model relates to the field of gypsum production, in particular to gypsum powder homogenizing equipment. Background Art

[0002] The increasing popularity of gypsum products has placed increasingly stringent demands on the stability of gypsum powder quality. Fluctuations in gypsum powder quality can, at best, cause fluctuations in the hydration reaction time of gypsum products, and, more severely, lead to serious quality issues such as cracking, hollowing, rapid setting, powder loss, and loss of strength in the gypsum mortar. The homogenization process of gypsum powder is accomplished by absorbing water molecules from the air and undergoing a hydration reaction. This process converts anhydrous gypsum into hemihydrate gypsum, while simultaneously healing surface defects in the gypsum grains through the hydration reaction, resulting in stable and uniform gypsum powder properties.

[0003] Currently, most manufacturers store gypsum powder in breathable ton bags or woven bags. This long-term storage allows the gypsum powder to absorb water molecules from the air and react to achieve homogenization. This method results in a long processing cycle, large space requirements, poor uniformity, and the risk of under- or over-homogenization. Furthermore, existing gypsum powder homogenization equipment suffers from slow homogenization rates and inconvenient cleaning of the equipment interior.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0033] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0034] Example 1

[0035] like Figures 1 to 4 As shown, a gypsum powder homogenizing equipment includes a tank body 1, a feed pipe 2 is installed on one side of the upper end of the tank body 1, a feed funnel 3 is installed on the other end of the feed pipe 2, the lower end of the feed funnel 3 is threadedly connected to the inside of the feed pipe 2, the feed funnel 3 can be disassembled, and a screen 30 is installed inside the feed funnel 3. Gypsum powder is poured into the feed funnel 3 and filtered through the screen 30. Qualified gypsum powder enters the tank body 1 for homogenization. The agglomerated gypsum powder is located at the upper end of the screen 30 and is processed after the feed funnel 3 is disassembled.

[0036] An air inlet pipe 4 is installed on one side of the lower end of the tank body 1, and gas is passed into the air inlet pipe 4. The gas can be hot and humid exhaust gas discharged from a calcination or drying kiln. An air outlet pipe 5 is installed on one side of the upper end of the tank body 1. The exhaust gas is released through the air outlet pipe 5 after being homogenized with the gypsum powder. A one-way air outlet structure 9 is installed inside the air outlet pipe 5 to prevent external air from entering the tank body 1 and affecting homogenization.

[0037] The one-way air outlet structure 9 includes a limit block 22, two limit blocks 22 are installed on both sides of the lower end of the outlet pipe 5, a baffle 23 is located at the upper end of the two limit blocks 22, a moving rod 24 is installed on the upper end of the baffle 23, a slider 25 is installed on the upper end of the moving rod 24, a partition 27 is installed on the upper end of the frame 26, the partition 27 is fixedly installed on the upper end of the outlet pipe 5, a through hole 28 is opened inside the partition 27, a spring 29 is installed inside the frame 26, the lower end of the spring 29 is connected to the slider 25, and the slider 25 is located inside the frame 26. When the exhaust gas inside the tank body 1 is excessive and needs to be discharged, the exhaust gas moves upward through the exhaust pipe 5, thereby driving the baffle 23 to move upward. The baffle 23 drives the slider 25 to move upward inside the frame 26 through the moving rod 24. The slider 25 compresses the spring 29. At this time, a gap is generated between the baffle 23 and the limit block 22, and the exhaust gas passes through and then flows out from the through hole 28. When the air pressure inside the tank body 1 is stable, the spring 29 recovers, causing the baffle 23 to return to above the limit block 22, and the exhaust pipe 5 is blocked, isolating it from the outside air.

[0038] The transmission structure 7 is arranged at the upper end of the tank body 1 , and the wall scraping structure 8 is arranged inside the tank body 1 . The wall scraping structure 8 is connected to the transmission structure 7 .

[0039] The transmission structure 7 includes a motor 10, which is fixedly installed in the middle of the upper end of the tank body 1, and a rotating rod 11 is installed at the output end of the lower end of the motor 10.

When rotating rod 1 11 rotates, it drives bevel gear 1 13 to rotate, thereby driving bevel gear 2 14 and bevel gear 3 15 to rotate. Bevel gear 1 13 and bevel gear 3 15 rotate in opposite directions, and bevel gear 3 15 drives rotating rod 2 16 to rotate. Therefore, when motor 10 is started, it can synchronously drive rotating rod 1 11 and rotating rod 2 16 to rotate in opposite directions.
