Description

Technical Field

[0001] The invention relates to the technical field of water reducing agent production devices, in particular to a slow-setting water reducing agent and an automated production device thereof. Background Art

[0002] Water reducers are divided into powders and aqueous solutions. Powders are made by drying aqueous solutions in order to reduce transportation costs. In normal use, the powder needs to be added with water to make an aqueous solution. The existing equipment first puts water into a mixing barrel, then pours the powder into it and stirs and mixes it.

[0003] After the powder is poured into the mixing barrel, it is easy to float and adhere to the upper wall of the mixing barrel, thereby reducing the mass of powder dissolved in water and causing the prepared aqueous solution to fail to reach the set concentration ratio. At the same time, most powders are packaged in bags. When the bagged powder is opened and poured into the mixing barrel, it may spill out of the mixing barrel. At this time, part of the whole bag of powder has already been poured into the barrel, so the actual amount added cannot be calculated, resulting in the aqueous solution mixed out of the mixing ratio not meeting the concentration ratio requirements.

A guide rod 141 is provided on the lower end surface of the sliding plate 14, and the diameter of the guide rod 141 is consistent with the guide hole 131 and the blanking hole 121, and the number and position are consistent with the number and position of the guide holes 131 on the guide plate 13. When the sliding plate 14 is pressed on the guide plate 13, the lower end of the guide rod 141 is just located in the blanking hole 121, thereby blocking the blanking hole 121. A guide column 123 is also provided on the rotating plate 12, and a ring cover 15 is provided on the guide column 123 for guiding sliding. The ring cover 15 is C-shaped, and the ring cover 15 is combined with the guide plate 13 and the rotating disk 12 to form a accommodating chamber 16, and when the sliding plate 14 is pressed on the guide plate 13, a blanking opening 161 is provided at the upper end of the accommodating chamber 16.

[0025] In the initial state, the blanking opening 161 in the blanking station is aligned with the feed hopper 17, so that the powder in the feed hopper 17 can automatically fall into the accommodating chamber 16, and a vibrator is provided on the feed hopper 17 to generate vibration when blanking, so that the accommodating chamber 16 is filled with powder under the action of vibration force, and the two side walls of the three ring covers 15 touch each other to form a complete ring, and the upper end surface of the ring cover 15 is flush with the upper plane when the sliding plate 14 is pressed against the guide plate 13. When the station is converted, the upper end surface of the ring cover 15 and the upper end surface of the sliding plate 14 can be tightly attached to the lower end surface of the feed hopper 17, so that the powder in the feed hopper 17 can only fall downward into the accommodating chamber 16 through the blanking opening 161 between the ring cover 15 and the sliding plate 14, and will not flow out to other positions.

[0026] The upper end of the mixing barrel 1 is provided with a mounting plate 18, and the water mixing device 3 includes a top-touch rod 31, a down-pressing rod 32 and an electromagnet 33. The electromagnet 33 is provided on the mounting plate 18, the top-touch rod 31 is slidably provided on the mounting plate 18, the down-pressing rod 32 is elastically slidably provided on the mounting plate 18, and a blocking plate 321 is provided at the lower end of the down-pressing rod 32. The upper end of the top-touch rod 31 is connected to one end of a pull rope 34, and the other end is connected to the upper end of the down-pressing rod 32. The top-touch rod 31 slides upward and pulls the down-pressing rod 32 downward through the pull rope 34, and the sliding A magnetic block 143 is provided on the plate 14, and a water inlet 144 is opened on the upper end surface of the magnetic block 143, and a plurality of water spray holes 142 are evenly opened in the circumferential direction of the lower end of each guide rod 141, and the water spray holes 142 are connected with the water inlet 144 through internal pipes, a water outlet pipe 331 is provided on the lower end surface of the electromagnet 33, and a quantitative water pump 181 is provided on the mounting plate 18, and the quantitative water pump 181 is connected with the water outlet pipe 331 through a pipe, and the quantitative water pump 181 can provide a quantitative amount of water to the water outlet pipe 331.

[0027] A servo motor 19 is provided on the mounting plate 18, and a second gear 191 is provided on the rotating shaft of the servo motor 19. The second gear 191 is meshed with the first gear 122. Each time the servo motor 19 is started, the rotating turntable 12 is driven to rotate one station. The servo motor 19 is started to rotate the accommodating chamber 16 originally located in the blanking station to the water inlet station. At this time, the magnetic block 143 is just located at the lower end of the electromagnet 33, and the water inlet 144 is aligned with the water outlet pipe 331. At this time, the electromagnet 33 is powered on and started, so that the sliding plate 14 is upwardly adsorbed on the electromagnet 33. At this time, the water inlet 144 is inserted into the water outlet pipe 331. The guide rod 141 moves upward to the uppermost end, the water spray hole 142 is located at the upper end of the accommodating chamber 16, and the blanking hole 121 is in an open state. In the process of the sliding plate 14 sliding upward, the top contact rod 31 is driven to move upward, thereby pulling one end of the pull rope 34 to move upward, and pulling the lower pressure rod 32 connected to the other end to slide downward, so that the blocking plate 321 is just located in the blanking opening 161. Since the size of the blocking plate 321 is consistent with the blanking opening 161, and a sealing strip is provided on the periphery of the blocking plate 321, the blanking opening 161 is blocked, so that the accommodating chamber 16 has only one opening, the blanking hole 121.

[0028] When the water inlet 144 is inserted into the water outlet pipe 331, the pressure-touch switch in the water inlet 144 is pressed to start the quantitative water pump 181, and the water spray hole 142 starts to spray water. The water is sprayed on the powder to dissolve the powder. The water dissolved in the powder falls downward from the drop hole 121 into the mixing barrel 1, and the stirring rod 11 in the mixing barrel 1 is in a rotating state, so as to mix and stir the fallen aqueous solution. After the quantitative water pump 181 sprays a set amount of water, the water supply is stopped. At this time, all the powder in the accommodating chamber 16 is flushed into the mixing barrel 1 by the water, and then stirred by the stirring rod 11 to form an aqueous solution with a set concentration ratio.

[0029] After the quantitative water pump 181 completes the water supply, it pauses for a period of time to allow all the water in the accommodating chamber 16 to flow out, and then the electromagnet 33 is automatically powered off, and the sliding plate 14 automatically slides downward under the action of gravity and presses on the guide plate 13 again, and the lower pressure rod 32 automatically resets upward under the action of elastic force and returns to its initial state.

[0030] After the electromagnet 33 is powered off, the servo motor 19 starts to start again, and rotates the accommodating chamber 16 previously located in the water inlet station to the drying station.

[0031] The drying device 4 includes a blowing hood 41 arranged on the mounting plate 18, and a second electromagnet 411 is arranged on the blowing hood 41. The annular cover 15 is a C-shaped structure, and the annular cover 15 is arranged on the rotating disk 12 for upward and downward guiding sliding. The second electromagnet 411 is energized to adsorb the annular cover 15 upward, and an air outlet 42 is arranged on the side of the mixing barrel 1. When the annular cover 15 is upwardly adsorbed on the blowing hood 41, an opening appears between the lower end of the annular cover 15 and the rotating disk 12, and the opening is aligned with the air outlet 42. A blowing device is arranged on the blowing hood 41, which can draw external air into the blowing hood 41, thereby blowing the annular cover 15, and the wind enters the accommodating chamber 16 from the blanking opening 161, and is then discharged outward from the air outlet 42, thereby drying the surrounding wall in the accommodating chamber 16.

[0032] After the workstation conversion is completed, the electromagnet 33 starts again to spray water on the accommodating chamber 16 that has newly entered the water inlet station. The second electromagnet 411 is energized synchronously to adsorb the annular cover 15 upward, so that the bottom of the annular cover 15 is aligned with the opening of the rotating disk 12 and the air outlet 42. The blowing device starts to draw outside air into the blowing hood 41, and the wind enters the accommodating chamber 16 from the blanking opening 161, and is then discharged outward from the air outlet 42, thereby drying the surrounding wall of the accommodating chamber 16. After the electromagnet 33 is automatically powered off, the second electromagnet 411 is powered off synchronously, causing the annular cover 15 to fall downward, press against the rotating disk 12 again, and return to its initial state.

[0033] Its working principle or usage is as follows:

[0034] In the initial state, the feed hopper 17 vibrates to feed the accommodating chamber 16 below. After the feeding is completed, that is, after a certain period of time, the servo motor 19 is started to realize the station conversion, and the accommodating chamber 16 originally located in the blanking station is rotated to the water inlet station, the accommodating chamber 16 previously located in the water inlet station is rotated to the drying station, and the accommodating chamber 16 previously located in the drying station is rotated to the blanking station.

[0035] After the accommodating chamber 16 in the blanking station rotates to the water inlet station, the electromagnet 33 is energized and started, and the sliding plate 14 is adsorbed upward on the electromagnet 33, and the water inlet 144 is inserted into the water outlet pipe 331. At this time, the guide rod 141 moves upward to the uppermost end, and the water spray hole 142 is located at the upper end of the accommodating chamber 16. The blanking hole 121 is in an open state. In the process of the sliding plate 14 sliding upward, the top contact rod 31 is driven to move upward, and the lower pressure rod 32 is pulled to slide downward, so that the sealing plate 321 is just located in the blanking opening 161. Since the size of the sealing plate 321 is consistent with the blanking opening 161, and a sealing strip is provided on the periphery of the sealing plate 321, the blanking opening 161 is blocked, so that the accommodating chamber 16 has only one opening, the blanking hole 121.

[0036] When the water inlet 144 is inserted into the water outlet pipe 331, the pressure-touch switch in the water inlet 144 is pressed to start the quantitative water pump 181, and the water spray hole 142 starts to spray water. The water is sprayed on the powder to dissolve the powder. The water dissolved in the powder falls downward from the drop hole 121 into the mixing barrel 1, and the stirring rod 11 in the mixing barrel 1 is in a rotating state, so as to mix and stir the fallen aqueous solution. After the quantitative water pump 181 sprays a set amount of water, the water supply is stopped. At this time, all the powder in the accommodating chamber 16 is flushed into the mixing barrel 1 by the water, and then stirred by the stirring rod 11 to form an aqueous solution with a set concentration ratio.

[0037] After the quantitative water pump 181 completes the water supply, it pauses for a period of time to allow all the water in the accommodating chamber 16 to flow out, and then the electromagnet 33 is automatically powered off, and the sliding plate 14 automatically slides downward under the action of gravity and presses on the guide plate 13 again, and the lower pressure rod 32 automatically resets upward under the action of elastic force and returns to its initial state.

[0038] After the electromagnet 33 is powered off, the servo motor 19 starts to start again, and rotates the accommodating chamber 16 previously located in the water inlet station to the drying station.

[0039] After the work station conversion is completed, the electromagnet 33 starts again to spray water on the accommodating chamber 16 that has newly entered the water inlet station. The second electromagnet 411 is energized synchronously to adsorb the annular cover 15 upward, so that the bottom of the annular cover 15 is aligned with the opening of the rotating disk 12 and the air outlet 42. The blowing device starts to draw outside air into the blowing hood 41, and the wind enters the accommodating chamber 16 from the blanking opening 161, and is then discharged outward from the air outlet 42, thereby drying the surrounding wall of the accommodating chamber 16. After the electromagnet 33 is automatically powered off, the second electromagnet 411 is powered off synchronously, causing the annular cover 15 to fall downward, press against the rotating disk 12 again, and return to its initial state.

[0040] After a round of station conversion is completed at the initial startup, after the station is converted again, the electromagnet 33, the second electromagnet 411 and the vibrator are powered on and off synchronously, and then start automatic continuous operation to mix and stir the powder into an aqueous solution that meets the required proportion.

[0041] A finished product flow pipe is provided at the bottom of the mixing barrel 1, and an electric valve is provided on the finished product flow pipe. When the servo motor 19 is started, that is, after a quantitative mixing is completed, the electric valve is opened synchronously to discharge the solution in the mixing barrel 1 to the outside. When the servo motor 19 stops, the electric valve is closed synchronously to stop providing the solution to the outside.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
