In practical application, the controller can control the quantitative feeder 19 to be opened or closed, the quantitative feeder 19 can be driven by the motor, and then the controller controls the motor to drive the quantitative feeder 19 to quantitatively drop materials into the sieving machine 18, so that the purpose of automatically and remotely controlling the dropping materials of the storage tank 10 is achieved, and the production efficiency is improved.
The inorganic board powder premixing system also comprises a sieving machine 18, the sieving machine 18 is used for sieving powder particles with different diameters, the top of the sieving machine 18 is communicated with the discharge hole at the bottom of the storage tank 10, and the bottom of the sieving machine 18 is communicated with the feed hole of the screw feeder 11.

Preferably, the storage tanks 10 are provided with more than two storage tanks, wherein the feed inlet of each storage tank 10 is correspondingly connected with a feed pipeline, and then the controller controls the feed pipelines to correspondingly feed different kinds of powder into the inner cavity of each storage tank. Thus completing the automatic feeding work of various powders.

Therefore, the effect of premixing and metering various powder materials is realized.
The air supply means 20 connected to the air inlet of the air duct 14 is a pneumatic pump for the purpose of achieving the initial premixing of the powders in the first homogenizer 13. Then the controller is electrically connected with the pneumatic pump, so that the controller controls the pneumatic pump to pump high-pressure gas, and the high-pressure gas is conveyed into the first homogenizer 13 through the gas conveying pipeline 14, and the primary premixing of the powder in the first homogenizer 13 is completed.
For the purpose of secondary premixing of the second homogenizer 16 to the powder, a stirring blade is provided in the second homogenizer 16, and the stirring blade is electrically connected with a driver, and the adopted driver can be a motor or other equipment for providing power. Then, the driver is controlled by the controller, the controller can control the start or stop or steering of the driver, and the stirring paddle is driven by the driver to turn over and mix the powder at a high speed to complete the secondary premixing of the powder.
In order to achieve the purpose of dust-free powder conveying and premixing, the controller controls a sealed conveying mode in the process of conveying powder to the storage tank 10 by the feeding pipeline, then, a feeding hole and a discharging hole of the feeding pipeline 15 respectively form a sealed communicating relation with the first homogenizer 13 and the second homogenizer 16, and then, the feeding pipeline 15 is also in a sealed communicating relation with the first homogenizer 13 and the second homogenizer 16.
Further, dust collectors 17 for exhausting air or dust are connected to the top of the storage tank 10, the first homogenizer 13, and the second homogenizer 16, respectively, since the powder transportation and the premixing in this embodiment are performed in a sealed environment. Therefore, when the storage tank 10, the first homogenizer 13 and the second homogenizer 16 are to be blanked or discharged, the controller controls the dust collector 17 to depressurize the storage tank 10, the first homogenizer 13 and the second homogenizer 16, thereby allowing the powder to enter the equipment of the next process. Of course, during the process of pressure relief of the dust collector 17, the dust collection function can be started to absorb dust generated by the powder in the storage tank 10, the first homogenizer 13 and the second homogenizer 16. Therefore, on the basis of sealing and premixing of pipelines and equipment, the dust collector is combined, the problem of large dust caused by powder can be effectively solved, environmental pollution is prevented, and the physical health of workers is guaranteed.
The pressure of the high pressure gas input to the first homogenizer 13 by the gas supply device 20 through the gas transmission pipeline 14 is in the range of 0.3Mpa to 0.5Mpa. In practical applications, the pressure of the high-pressure gas can be set to be any one of 0.30 Mpa, 0.35Mpa, 0.40Mpa, 0.45Mpa and 0.50Mpa, wherein the setting of the pressure of the high-pressure gas to be 0.35Mpa is the most preferable scheme.
The primary premixing time of the powder in the first homogenizer 13 is 55s-65s. In practical applications, the time of the first premixing may be set to be any one of 55s or 58s or 60s or 62s or 65s, wherein the setting of the time of the first premixing to be 60s is the optimal solution.
The embodiment in which the pressure of the high pressure gas is set to 0.35Mpa and the time for the initial premixing is set to 60s is determined to be optimal in combination with the above setting of the pressure value of the high pressure gas and the setting requirement of the initial premixing time because the time taken for the first homogenizer 13 to initially premix the powder with the high pressure gas of 0.35Mpa to achieve the mixing effect required by the user is exactly 60s when the high pressure gas supplied from the gas supply means 20 to the first homogenizer 13 is set to 0.35 Mpa; when the pressure of the high-pressure gas is set to be 0.3Mpa, the time for achieving the primary premixing effect of the powder is 70s, and the premixing efficiency is low; and when the pressure of the high-pressure gas is set to 0.50Mpa, although the time for the primary premixing can be shortened, it is easy to cause equipment fatigue to the gas delivery pipe 14 and the first homogenizer 13, reducing the service life. In conclusion, the pressure of the high-pressure gas of 0.35MPa and the time for the initial premixing of 60s are more advantageous than the initial premixing of the pulverized material under the high-pressure gas with other pressure values.
The time for the secondary premixing of the powder in the second homogenizer 16 is 110s-130s, and in practical application, the time for the primary premixing can be set to be any one of 110s, 115s, 120s, 125s and 130s, wherein the optimal scheme is that the time for the secondary premixing is set to be 120 s.
The second homogenizing machine 16 is provided with a discharge port communicated with the next procedure, the second homogenizing machine 16 discharges the secondarily premixed powder to the equipment of the next procedure through the discharge port, and the discharge time of the discharge port of the second homogenizing machine 16 is 80-100 s. In practical applications, the discharge time of the second homogenizer 16 can be set to any one of 80s or 85s or 90s or 95s or 100s, wherein the time for the second premixing is set to 90s is the most preferable scheme.
In combination with the above requirements for setting the time for the second premixing by the second homogenizer 16 and setting the time for the discharge, setting the time for the second premixing to 120s and setting the time for the discharge to 90s is an optimal solution because when the premixing time is set to 110s, the premixing effect of the powder can reach the standard, but there is a slight difference from the premixing time of 120s, and when the premixing time is set to 130s, the too long time for the premixing time affects the production efficiency; and in combination with the discharging time, when the discharging time is set to 80s, although the discharging requirement can be basically met, a small amount of powder which does not reach the time length of the secondary premixing is also discharged to equipment of the next process, and when the discharging time is set to 130s, the production efficiency is also influenced. In conclusion, the time of 120s of secondary premixing and the time of 90s of discharging are more advantageous than the secondary premixing under the conditions of secondary premixing and discharging of other powder materials.
Taking the powder premixing of raw materials of inorganic plates as an example, the powder premixing of the conventional inorganic plates is performed by using a horizontal mixer, but when the powder premixing is performed by the horizontal mixer, manual feeding is required, and online production cannot be performed; and only single-stage premixing is carried out, the premixing time is long, the premixing is not uniform, the grading phenomenon is easy to occur, and the problems of low production efficiency and unqualified quality of inorganic boards can be caused.
In the embodiment of the application, the powder is subjected to two-stage premixing by remotely and automatically controlling the actions of the powder conveying and premixing steps and configuring the first homogenizer 13 and the second homogenizer 16, so that the powder is premixed more fully, the powder premixing time is shortened, and the production efficiency and quality of an inorganic board can be effectively improved. The operation method of the embodiment of the present application is as follows, as shown in fig. 1:
(1) The controller controls the feeding pipelines to respectively convey various powder materials into the corresponding storage tanks 10, and at the moment, the controller controls the dust collector 17 to release the air pressure in the storage tanks 10, so that the powder materials freely fall into the storage tanks 10;
(2) The controller controls the constant feeder 19 of the storage tank 10 to be opened, so that the powder falls into the sieving machine 18 to be screened according to the diameter size to obtain the powder meeting the requirement, and then the controller controls the screw feeder 11 to convey the powder meeting the diameter size to the metering device 12;
(3) The metering device 12 is used for metering a plurality of mixed powder materials, the metered powder materials are distributed into the first homogenizer 13, and then the controller controls the gas supply device 20 to enable high-pressure gas generated by the gas supply device 20 to be conveyed into the first homogenizer 13 through the gas conveying pipeline 14 to vulcanize and disperse the powder materials, so that primary premixing of the powder materials is completed;
(4) The powder after the primary premixing is circulated to a second homogenizer 16 through a material conveying pipeline 15 along with the high-pressure gas, at the moment, a controller controls a dust collector 17 to release the air pressure in the second homogenizer 16, so that the powder can be conveyed to an inner cavity of the second homogenizer 16 along with the high-pressure gas from a gas conveying pipeline 14; then, the controller controls a stirring mechanism in the second homogenizer 16 to turn over and mix the powder at a high speed to complete the secondary premixing of the powder; and finally, the secondarily premixed powder falls into the equipment of the next procedure through a discharge hole of the second homogenizer 16.
