FIG. 1 is a schematic structural diagram of a preparation facilities of gypsum board water-reducing agent in this application embodiment.
Detailed Description
As shown in fig. 1, fig. 1 shows a device for preparing a gypsum board water reducing agent in the present embodiment. The preparation device comprises a preparation tank 11, a first stirrer 18, a first liquid level meter 14, a first valve 12, a second valve 16, a discharging channel 15, a discharging hopper 17 and a control circuit.
The preparation tank 11 has a tank-like structure. The preparation tank 11 may be a tank body having a substantially cylindrical outer contour. The upper end of the preparation tank 11 is provided with a water inlet 111 and a first feed inlet 112, and the lower end of the preparation tank 11 is provided with a first discharge outlet 113. The water inlet 111 is connected to a water supply pipe 13, and the water supply pipe 13 can supply water into the preparation tank 11 through the water inlet 111. The first valve 12 is used to open and close the preparation tank 11. The first valve 12 may be a solenoid valve. The first valve 12 may be disposed at the water inlet 111, and the first valve 12 may be disposed at the water supply pipe 13.
The lower hopper 17 is disposed above the preparation tank 11. The lower hopper 17 is funnel-shaped. The bottom of the lower hopper 17 is provided with an opening. The upper end of the discharge channel 15 is connected to an opening at the bottom of the discharge hopper 17. The first feed opening 112 of the preparation tank 11 is connected to the lower end of the blanking passage 15. The lower hopper 17 can contain a solid water reducing agent 5 therein. The blanking channel 15 is used for inputting the solid water-reducing agent 5 in the blanking hopper 17 into the first feed port 112. And a second valve 16 is arranged on the blanking channel 15 and used for opening and closing the preparation tank 11 to convey the solid water reducing agent 5. The second valve 16 may be an electrically operated valve. The water input into the preparation tank 11 from the water inlet 111 and the solid water-reducing agent 5 input into the preparation tank 11 from the first feed opening 112 can be mixed into a liquid water-reducing agent in the preparation tank 11.
The first stirrer 18 is arranged on the preparation tank 11 and is used for uniformly stirring the solid water reducing agent 5 and the water. The first mixer 18 includes a first motor 181, a first reducer 182, a first mixing shaft (not shown), and a first impeller (not shown). The first decelerator 182 is provided at the top of the preparation tank 11. The first motor 181 is disposed above the first decelerator 182, and is drivingly connected to an input shaft of the first decelerator 182. The first stirring shaft extends into the preparation tank 11 from the first speed reducer 182, and the first stirring shaft is connected to an output shaft of the first speed reducer 182 in a transmission manner. The first impeller is arranged in the preparation tank 11 and sleeved on the first stirring shaft. The torque output by the first motor 181 is reduced and increased by the first speed reducer 182, and then drives the first stirring shaft to drive the first impeller to rotate. The first impeller can stir the solid water reducing agent 5 and the water in the preparation tank 11 after rotating, so that the solid water reducing agent 5 and the water are uniformly mixed. The first impeller and the first stirring shaft may be both disposed coaxially with the preparation tank 11.
A first level gauge 14 is provided at the lower end of the preparation tank 11. The first level meter 14 can measure the level height of the liquid in the preparation tank 11.
The control circuit is electrically connected to the first blender 18, the first level gauge 14, the first valve 12 and the second valve 16, respectively, by electrical cables. The first gauge 14 sends its measurement to the control circuit.
The control circuit is configured to:
after receiving a command of starting to prepare the liquid water reducing agent, the control circuit obtains the current liquid level in the preparation tank 11 measured by the first liquid level meter 14, and drives the first valve 12 to open when the current liquid level is less than a first preset liquid level 114;
after the control circuit drives the first valve 12 to be opened, the control circuit obtains the liquid level in the preparation tank 11 measured by the first liquid level meter 14 in real time, and when the liquid level is greater than or equal to a first preset liquid level 114, the control circuit drives the first valve 12 to be closed, the second valve 16 to be opened and the first stirrer 18 to be started;
when the starting time of the first stirrer 18 reaches the preset time, the control circuit drives the first stirrer 18 to stop, and simultaneously closes the second valve 16.
When the preparation device is used, the first valve 12 and the second valve 16 are both in a closed state, and after the solid water reducing agent 5 is placed into the discharging hopper 17 through the crane 4, an instruction for starting preparation of the liquid water reducing agent is sent to the control circuit through the starting switch. The control circuit obtains the measurement result of the first liquid level meter 14 after receiving the instruction of starting to prepare the liquid water reducing agent, and drives the first valve 12 to open when the current liquid level in the preparation tank 11 measured by the first liquid level meter 14 is less than the first preset liquid level 114. After the first valve 12 is opened, the water supply pipe 13 injects water into the preparation tank 11 through the water inlet 111, the liquid level in the preparation tank 11 rises, and the first liquid level meter 14 measures the liquid level in the preparation tank 11 in real time during the process and transmits the liquid level to the control circuit. When the first level meter 14 detects that the liquid level in the preparation tank 11 rises to the first preset liquid level 114, the first valve 12 is closed so that the water supply pipe 13 stops supplying water into the preparation tank 11. When the water in the preparation tank 11 reaches the first preset liquid level 114, the mass ratio of the water in the preparation tank 11 to the solid water reducing agent 5 in the blanking hopper 17 reaches the mixing ratio required for preparing the liquid water reducing agent. When the first valve 12 is closed, the second valve 16 and the first stirrer 18 are opened, after the second valve 16 is opened, the solid water reducing agent 5 in the discharging hopper 17 sequentially passes through the discharging channel 15 and the first feeding hole 112 to enter the preparation tank 11, and when the solid water reducing agent 5 falls into water, the first stirrer 18 stirs the mixture of the solid water reducing agent 5 and the water, so that the solid water reducing agent 5 and the water can be uniformly mixed to obtain the liquid water reducing agent. When the starting time of the first stirrer 18 reaches the preset time, the control circuit drives the first stirrer 18 to stop. The preset time period can be set to be more than or equal to the time for fully and uniformly mixing the solid water reducing agent 5 and the water.
Therefore, the preparation device can automatically mix the solid water reducing agent 5 and water together according to a preset mixing proportion, and automatically and fully mix the solid water reducing agent 5 and the water to obtain the liquid water reducing agent.
In an exemplary embodiment, the preparation device further comprises a first heater 19 and a first temperature sensor 20. The first heater 19 and the first temperature sensor 20 are electrically connected to the control circuit through a cable.
The first heater 19 is disposed at the lower end of the preparation tank 11. The first level gauge 14 is located at a lower level than the first heater 19. The first heater 19 is located at a height less than the first predetermined level 114. The first heater 19 may be installed on a sidewall of the preparation tank 11. The first heater 19 may be provided in plural, and the plural first heaters 19 are uniformly distributed around the circumference of the preparation tank 11. The first heater 19 may be an electric heater. The first heater 19 is used to heat the material in the preparation tank 11.
The first temperature sensor 20 is disposed at the lower end of the preparation tank 11. The first temperature sensor 20 may be installed on a sidewall of the preparation tank 11. The first temperature sensor 20 may be located at the same height as the first heater 19. The first temperature sensor 20 can detect the temperature of the material in the preparation tank 11 and send the detection result to the control circuit.
The control circuit is further configured to:
when the liquid level in the preparation tank 11 measured by the first liquid level meter 14 is greater than or equal to a second preset liquid level 115, the control circuit drives the first heater 19 to heat the liquid in the preparation tank 11, and the height of the second preset liquid level 115 is greater than the height of the first heater 19 and less than the height of the first preset liquid level 114;
the control circuit also negatively feedback-adjusts the heating power of the first heater 19 so that the temperature of the material in the preparation tank 11 is maintained at the first preset temperature, according to the temperature of the material in the preparation tank 11 measured by the first temperature sensor 20.
The first preset temperature is greater than or equal to 10 ℃ and less than or equal to 40 ℃. The first predetermined temperature is preferably 30 ℃.
After the first valve 12 is opened, the water supply pipe 13 injects water into the preparation tank 11, the water level in the preparation tank 11 gradually rises, and when the liquid level measured by the first liquid level meter 14 reaches the second preset liquid level 115, the control circuit drives the first heater 19 to heat the water. The first temperature sensor 20 acquires the temperature of the liquid in the preparation tank 11 in real time and sends the measured temperature to the control circuit. The control circuit negatively feeds back the heating power of the first heater 19 according to the temperature measured by the first temperature sensor 20, so that the temperature of the liquid in the preparation tank 11 is maintained at the first preset temperature. For example, the heating power of the first heater 19 is decreased when the temperature of the liquid in the preparation tank 11 is greater than a first preset temperature, and the heating power of the first heater 19 is increased when the temperature of the liquid in the preparation tank 11 is less than the first preset temperature.
Therefore, the liquid temperature in the preparation tank 11 can be heated to a first preset temperature, and the first preset temperature is greater than or equal to 10 ℃, so that the crystallization of the liquid water reducing agent formed by mixing the solid water reducing agent 5 and water at the temperature lower than 10 ℃ can be avoided, and then a pipeline at the downstream of the preparation tank 11 is blocked.
In an exemplary embodiment, the preparation device further includes a holding tank 21, a second blender 24, a second level gauge 26, and a first pump body 22.
The first pump body 22 includes a first inlet and a first outlet. The first inlet is connected to the first discharge port 113 of the preparation tank 11. The first pump body 22 may be a reverse fill pump.
A second stirrer 24 is provided on the reserve tank 21 for stirring the liquid water-reducing agent. The second mixer 24 includes a second motor 241, a second reducer 242, a second mixing shaft (not shown), and a second impeller (not shown). The second decelerator 242 is provided at the roof of the reserve tank 21. The second motor 241 is disposed above the second speed reducer 242, and is drivingly connected to an input shaft of the second speed reducer 242. The second stirring shaft extends into the reserve tank 21 from the second speed reducer 242, and the second stirring shaft is connected to an output shaft of the second speed reducer 242 in a transmission manner. The second impeller is arranged in the storage tank 21 and sleeved on the second stirring shaft. The torque output by the second motor 241 is reduced and increased by the second reducer 242, and then drives the second stirring shaft to drive the second impeller to rotate. The second impeller can stir the liquid water reducing agent in the storage tank 21 after rotating. The second impeller and the second stirring shaft may both be disposed coaxially with the reserve tank 21. The second blender 24 is normally open.
A second level gauge 26 is provided at the lower end of the reserve tank 21. The second level gauge 26 can measure the level of the liquid in the reserve tank 21.
The control circuit is further configured to:
when the second valve 16 is closed, the first pump body 22 is driven to start;
after the control circuit drives the first pump body 22 to start, the control circuit obtains the liquid level in the reserve tank 21 measured by the second liquid level meter 26 in real time, and drives the first pump body 22 to close when the liquid level is greater than or equal to the third preset liquid level 213. Third preset level 213 may be disposed near the top of reserve tank 21.
When the second valve 16 is closed, the liquid water-reducing agent in the preparation tank 11 has been completely prepared, the control circuit drives the first pump body 22 to pump the liquid water-reducing agent in the preparation tank 11 into the reserve tank 21, and the liquid level in the reserve tank 21 gradually rises. When the second level gauge 26 detects that the liquid level in the reserve tank 21 rises to the third preset liquid level 213, the control circuit closes the first pump body 22 to prevent the reserve tank 21 from being filled and overflowing. The capacity of the storage tank 21 may be the same as the capacity of the preparation tank 11, and the liquid water-reducing agent prepared in the preparation tank 11 is transferred to the storage tank 21, so that the preparation tank 11 can be emptied to allow the preparation tank 11 to perform the next preparation of the liquid water-reducing agent. The second stirrer 24 is normally opened, and can stir the liquid water reducing agent in the storage tank 21, so that the liquid water reducing agent is always kept uniformly mixed.
In an exemplary embodiment, the preparation device further comprises a second heater 25 and a second temperature sensor 27. The second heater 25 and the second temperature sensor 27 are electrically connected to the control circuit through a cable.
The second heater 25 is provided at the lower end of the reserve tank 21. The second level gauge 26 is located at a lower level than the second heater 25. The second heater 25 is located at a height less than the third predetermined level 213. The second heater 25 may be installed on a sidewall of the reserve tank 21. The second heater 25 may be provided in plural, and the plural second heaters 25 are uniformly distributed around the circumferential direction of the reserve tank 21. The second heater 25 may be an electric heater. The second heater 25 is used for heating the liquid water reducing agent in the storage tank 21.
The second temperature sensor 27 is provided at the lower end of the reserve tank 21. Second temperature sensor 27 may be mounted on a side wall of reserve tank 21. The second temperature sensor 27 may be located at the same height as the second heater 25. The second temperature sensor 27 can detect the temperature of the liquid water-reducing agent in the reserve tank 21 and send the detection result to the control circuit.
The control circuit is further configured to:
when the liquid level in the storage tank 21 measured by the second liquid level meter 26 is greater than or equal to a fourth preset liquid level 214, the control circuit drives the second heater 25 to heat the liquid water reducing agent in the storage tank 21, and the height of the fourth preset liquid level 214 is greater than the height of the position of the second heater 25 and less than the height of the third preset liquid level 213;
the control circuit also negatively feedback-adjusts the heating power of the second heater 25 according to the temperature of the liquid water reducing agent in the storage tank 21 measured by the second temperature sensor 27 so that the temperature of the liquid in the storage tank 21 is maintained at a second preset temperature.
The second preset temperature is greater than or equal to 10 ℃ and less than or equal to 40 ℃. The second predetermined temperature is preferably 30 ℃.
After the first pump body 22 is opened, the first pump body 22 injects the liquid water reducing agent into the reserve tank 21, the liquid level in the reserve tank 21 gradually rises, and when the liquid level measured by the second liquid level meter 26 reaches the fourth preset liquid level 214, the control circuit drives the second heater 25 to heat the liquid water reducing agent. The second temperature sensor 27 acquires the temperature of the liquid water-reducing agent in the reserve tank 21 in real time, and sends the measured temperature to the control circuit. The control circuit negatively feedback-adjusts the heating power of the second heater 25 according to the temperature measured by the second temperature sensor 27 so that the temperature of the liquid in the reserve tank 21 is maintained at the second preset temperature. For example, the heating power of second heater 25 is decreased when the temperature of the liquid in reserve tank 21 is greater than the second preset temperature, and the heating power of second heater 25 is increased when the temperature of the liquid in reserve tank 21 is less than the second preset temperature.
Thereby, the liquid temperature in reserve tank 21 can be heated to a second preset temperature, which is greater than or equal to 10 ℃, which can avoid crystallization of the liquid water-reducing agent at a temperature lower than 10 ℃ and subsequent blockage of the piping downstream of reserve tank 21.
In an exemplary embodiment, the preparation device further comprises a second pump 27, a use tank 29 and a third level gauge 30. The third gauge 30 and the second pump body 27 are electrically connected to the control circuit.
The second pump body 27 may be a reverse fill pump. The second pump body 27 includes a second inlet and a second outlet. The second inlet is connected to a second discharge port 212 of reserve tank 21 through a pipe.

A third level gauge 30 is provided at the lower end of the use tank 29. The third level gauge 30 is capable of measuring the level of the liquid water-reducing agent in the use tank 29.

when the level of liquid in the use tank 29 measured by the third gauge 30 is greater than or equal to a fifth preset level 293, the control circuit drives the second pump 27 to close.
When the liquid level in the storage tank 21 measured by the second liquid level meter 26 is greater than or equal to the fourth preset liquid level 214, the liquid level of the liquid water reducing agent in the storage tank 21 is greater than the height of the second discharge port 212 of the storage tank 21, the control circuit drives the second pump body 27 to start, and the control circuit pumps the liquid water reducing agent from the storage tank 21 to the use tank 29. When the third level gauge 30 measures that the liquid level of the liquid water-reducing agent in the use tank 29 reaches the fifth preset liquid level 293, the control circuit closes the second pump body 27, and the liquid water-reducing agent in the use tank 29 can be prevented from overflowing.
The liquid water reducing agent in the tank 29 can be discharged at any time and used as a raw material for gypsum board production.
