Technical Field

[0001] The utility model relates to the field of gypsum powder production, in particular to a gypsum powder homogenization storage bin. 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] For example, the authorization announcement number is CN 216024810 U, a gypsum powder homogenization storage bin, including a bin body, a feed port is provided on the top of the bin body, a unloading assembly is provided on the bottom, a gypsum calcination exhaust gas inlet pipe is provided in the bin body, the exhaust gas inlet end of the gypsum calcination exhaust gas inlet pipe is located on the outer side of the lower part of the bin body, and the exhaust gas outlet end is located in the bin body and directly facing the feed port, and a distributor is provided directly above the exhaust gas outlet end, which can evenly disperse the material in the feed port to the periphery of the exhaust gas outlet end; the storage bin can realize rapid and uniform homogenization of gypsum powder, and effectively utilize the gypsum powder bin without increasing space occupancy.

[0004] However, in the above invention, the raw materials are accumulated in the silo, and the moist air enters the silo and stays on the upper end of the accumulated raw materials, only contacting the upper layer of the raw materials, which makes the hydration reaction relatively slow; therefore, the market urgently needs to develop a gypsum powder homogenization storage silo to help people solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to provide a gypsum powder homogenizing storage bin to solve the problem raised in the above background technology that most existing gypsum powder homogenizing storage bins pile up raw materials in the bin body, and moist air enters the bin body and stays on the upper end of the piled raw materials, only contacting the upper layer of the raw materials, resulting in a relatively slow hydration reaction.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gypsum powder homogenizing storage bin, comprising a homogenizing storage bin, wherein one side of the upper end of the homogenizing storage bin is provided with a feed port, and the lower end of the homogenizing storage bin is provided with a discharge port, the middle part of the interior of the homogenizing storage bin is rotatably connected to a rotating shaft, the middle part of the rotating shaft is fixedly provided with a first spiral blade, the lower end of the rotating shaft extends to the inside of the discharge port and is fixedly connected to a second spiral blade, the middle part of the upper end of the homogenizing storage bin is fixedly provided with a first driving device for driving the rotating shaft to rotate, one side of the homogenizing storage bin is fixedly connected to an air mixing box, the upper end of the mixing box is fixedly connected to an electrically controlled exhaust valve, the lower end of the mixing box is fixedly connected to a humidifier, an end face of one side of the interior of the mixing box is fixedly connected to an air pump, the air pump is communicated with the interior of the homogenizing storage bin by an air supply pipe, and the other side of the homogenizing storage bin is connected to the front end of the mixing box by a return air pipe.

[0007] Preferably, a first motor is fixedly disposed inside the first driving device.

[0011] Preferably, one end of the stirring shaft extends into the interior of the second driving device and is fixedly connected to the output shaft of the second motor.

[0012] Preferably, the lower end of the discharge port can be opened and connected with a sealing cover.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the utility model, through the setting of the first spiral blade, the middle part of the homogenizing storage bin is rotatably connected to the rotating shaft, and the first spiral blade is fixedly set in the middle of the rotating shaft. The first motor drives the rotating shaft to rotate slowly, and then synchronously drives the first spiral blade and the second spiral blade to rotate.

[0015] 2.

When the second spiral blade rotates, the raw materials inside the discharge port can be transported upward to prevent the raw materials from being stationary inside the discharge port and unable to come into contact with moist air for homogenization. When discharging, the cover is opened, and the first motor drives the rotating shaft to rotate slowly in the opposite direction, so that the second spiral blade rotates in the opposite direction, and the raw materials are transported outward through the discharge port, thereby improving the discharge efficiency.

[0016] 3. In this utility model, through the setting of the return air pipe, the other side of the homogenization storage bin is connected to the front end of the mixing box through the return air pipe. The air pressure inside the homogenization storage bin will increase due to the input of moist air by the air pump. The homogenized air inside the homogenization storage bin is returned to the mixing box through the return air pipe through the air pressure, so that the entire homogenization process is isolated from the outside air, preventing dust in the outside air from contaminating the raw materials.

[0023] See also Figure 1-4The utility model provides an embodiment of a gypsum powder homogenizing storage bin, comprising a homogenizing storage bin 1, a feeding port 101 is provided on one side of the upper end of the homogenizing storage bin 1, and a discharging port 102 is provided at the lower end of the homogenizing storage bin 1, a rotating shaft 2 is rotatably connected to the middle part of the interior of the homogenizing storage bin 1, a first spiral blade 201 is fixedly provided in the middle of the rotating shaft 2, and the lower end of the rotating shaft 2 extends to the inside of the discharging port 102 and is fixedly connected to the second spiral blade 202. A first driving device 3 is fixedly provided in the middle part of the upper end of the homogenizing storage bin 1 for driving the rotating shaft 2 to rotate, a mixing box 4 is fixedly connected to one side of the homogenizing storage bin 1, an electric-controlled exhaust valve 401 is fixedly connected to the upper end of the mixing box 4, a humidifier 402 is fixedly connected to the lower end of the mixing box 4, an air pump 5 is fixedly connected to the end face of one side of the interior of the mixing box 4, the air pump 5 is communicated with the interior of the homogenizing storage bin 1 through an air supply pipe 501, and the other side of the homogenizing storage bin 1 is connected to the front end of the mixing box 4 through an air return pipe 403.

[0024] Furthermore, a first motor 301 is fixedly disposed inside the first driving device 3 .

[0025] Furthermore, the upper end of the rotating shaft 2 extends to the interior of the first driving device 3 and is fixedly connected to the output shaft of the first motor 301. The first motor 301 drives the rotating shaft 2 to rotate slowly, and then synchronously drives the first spiral blade 201 and the second spiral blade 202 to rotate. When the raw materials enter the homogenizing storage bin 1 and are accumulated, the first spiral blade 201 rotates to transport the middle material of the accumulated raw materials upward, and the outer material flows downward under the action of gravity, so that the raw materials circulate inside the homogenizing storage bin 1. When the external humidified air enters the upper end of the homogenizing storage bin 1, the flowing raw materials can fully contact with the air, thereby improving the homogenization efficiency and making the homogenization more complete.

[0026] Furthermore, a stirring shaft 6 is rotatably connected to the interior of the gas mixing box 4 , and a plurality of blades 601 are fixedly connected to the stirring shaft 6 in an annular array.

[0027] Furthermore, a second driving device 7 for driving the stirring shaft 6 to rotate is fixedly connected to one side of the gas mixing box 4 , and a second motor 701 is fixedly provided inside the second driving device 7 .

[0028] Furthermore, one end of the stirring shaft 6 extends into the interior of the second driving device 7 and is fixedly connected to the output shaft of the second motor 701 . The stirring shaft 6 is driven by the second motor 701 to rotate slowly, thereby driving the blades 601 to rotate.

[0029] Furthermore, the lower end of the discharge port 102 can be opened and connected to a cover 103, and the lower end of the discharge port 102 is closed by the cover 103. When the second spiral blade 202 rotates, the raw materials inside the discharge port 102 can be transported upward to prevent the raw materials from being stationary inside the discharge port 102 and unable to come into contact with moist air for homogenization. When discharging, the cover 103 is opened, and the first motor 301 drives the rotating shaft 2 to rotate slowly in the opposite direction, causing the second spiral blade 202 to rotate in the opposite direction, and transporting the raw materials outward through the discharge port 102, thereby improving the discharge efficiency.

[0030] Working principle: When in use, the raw materials are added into the homogenizing storage bin 1 through the feed port 101. After the feeding is completed, the feed port 101 is closed, and the atomized water vapor is input into the mixing box 4 through the humidifier 402 (the humidifier 402 is only connected to the inside of the mixing box 4). The stirring shaft 6 is driven to rotate slowly by the second motor 701, and then the blade 601 is driven to rotate to mix the atomized water vapor with the air inside the mixing box 4, and the humidified air is input into the homogenizing storage bin 1 through the air pipe 501 through the air pump 5 to carry out homogenization reaction with the raw materials. At the same time, the rotating shaft 2 is driven to rotate slowly by the first motor 301, and then the first spiral blade 201 and the second spiral blade 202 are driven to rotate synchronously. When the raw materials enter the homogenizing storage bin 1 and accumulate, the first spiral blade 201 rotates to transport the middle material of the accumulated raw materials upward, and the outer material flows downward under the action of gravity, so that the raw materials are homogenized in the homogenizing storage bin 1. The humidified air from the outside enters the upper end of the homogenizing storage bin 1, and the raw materials in the flowing state can fully contact with the air, thereby improving the homogenization efficiency and making the homogenization more complete. The lower end of the discharge port 102 is closed by the sealing cover 103. When the second spiral blade 202 rotates, the raw materials inside the discharge port 102 can be transported upward to prevent the raw materials from being stationary inside the discharge port 102 and unable to contact with the humidified air for homogenization. When discharging, the sealing cover 103 is opened, and the first motor 301 drives the rotating shaft 2 to rotate slowly in the opposite direction, so that the second spiral blade 202 rotates in the opposite direction to transport the raw materials outward through the discharge port 102, thereby improving the discharging efficiency. The air pressure inside the homogenizing storage bin 1 increases due to the input of humidified air by the air pump 5. The homogenized air inside the homogenizing storage bin 1 is returned to the gas mixing box 4 through the return air pipe 403 through the air pressure, so that the entire homogenization process is isolated from the outside air, thereby preventing dust in the outside air from contaminating the raw materials.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
