Description

Technical Field

[0001] The invention relates to the field of wallboard production devices, and in particular to an automated production device for phosphogypsum wallboards. Background Art

[0002] Phosphogypsum is an industrial solid waste generated by the reaction of sulfuric acid and phosphate rock powder in the phosphoric acid production process of phosphate fertilizer production enterprises. Its main component is CaSO4·2H2O. Since phosphogypsum contains many harmful impurities such as phosphorus, fluorine, and organic matter, its performance is deteriorated, which increases the difficulty of comprehensive utilization of phosphogypsum. Modified gypsum composite wallboards and other products used in construction use phosphogypsum as the main raw material. No additional fuel is required during the production process. It is an environmentally friendly, waste-recycling, energy-saving and consumption-reducing project. Now we need a device that can automatically produce phosphogypsum wallboards, which can save manpower and material resources and make environmentally friendly use of phosphogypsum materials. Summary of the invention

[0003] The purpose of the present invention is to provide an automated production device for phosphogypsum wallboards that saves manpower and material resources and can reuse phosphogypsum materials in an environmentally friendly manner.

[0004] To achieve the above purpose, the technical solution is as follows:

[0005] The invention discloses an automatic production device for phosphogypsum wallboard, comprising a mixing tank, a forming mould, a wallboard through-hole device, a crane, a crane frame, a conveyor and a control system. The mixing tank is fixedly connected to the crane, the crane is slidably connected above the crane frame, the forming mould is fixed in the crane frame, the wallboard through-hole device is fixedly installed beside the forming mould, the wallboard through-hole device and the forming mould are in the same horizontal plane, the conveyor is fixedly erected above the mixing tank, the wallboard through-hole device and the forming mould are provided with electromagnets, the forming mould is provided with a single-pole double-throw switch, the single-pole double-throw switch controls the opening and closing of the electromagnets on the wallboard through-hole device and the forming mould, and the wallboard through-hole device, the conveyor, the crane, the mixing tank and the control system can be automatically operated in coordination.

[0006] The working principle of the present invention is as follows: the raw materials of the phosphogypsum wallboard are conveyed into a mixing tank by a conveyor, and after being stirred for a certain period of time, a uniformly mixed phosphogypsum wallboard raw material slurry is formed, and the mixing tank is hoisted to the top of the forming mold by a crane. At this time, a single-pole double-throw switch controls a wallboard through-hole device to be in an energized state, and the forming mold is in an off-power state. The control system starts the wallboard through-hole device, so that the wallboard through-hole device moves and is connected to the forming mold to form a whole. At this time, the single-pole double-throw switch is switched to control the wallboard through-hole device to be in an off-power state, and the forming mold is in an energized state, so that the electromagnet on the forming mold is energized to stably adsorb the wallboard through-hole device. At this time, the discharge port under the mixing tank is opened, and the uniformly mixed phosphogypsum wallboard raw material slurry in the mixing tank is poured into the forming mold, and the wallboard is automatically formed in the forming mold.

[0007] The advantages of the present invention are as follows: the present invention realizes the continuous combination of various production processes of the phosphogypsum wallboard through the coordination of the wallboard through-hole device, the conveyor, the crane, the mixing tank and the control system, realizes the intelligent automation of the production of the phosphogypsum wallboard, and controls the power-on and power-off states of the electromagnet on the wallboard through-hole device and the molding mold through switching by a single-pole double-throw switch, thereby utilizing the adsorption effect of the electromagnet to firmly connect the wallboard through-hole device and the molding mold into one body, and the through-hole device can be made into a phosphogypsum wallboard with through-holes by cooperating with the molding mold. Such phosphogypsum wallboard has a short air-drying time, accelerates the manufacturing rate of the phosphogypsum wallboard, and saves time and cost.

The frame door is opened to facilitate the removal of the formed phosphogypsum wallboard. When the frame door is closed, it can form multiple cubic spaces with the isolation plate and the molding frame. The cubic spaces can accommodate the formed phosphogypsum wallboards. The steel bar passed through the fixing hook can stabilize the frame door in a closed state.

The cylinder pushes the hole column plate, and the hole column frame holds the through-hole column. Finally, the through-hole column moves through the circular hole on the frame door and passes through the forming mold, thereby achieving the purpose of giving through holes to the phosphogypsum wallboard.

The opening at the upper end of the mixing tank 1 receives the raw materials of the phosphogypsum wallboard, and the mixing tank 1 is started by the PLC control system. The mixing propeller 11 can mix and evenly mix the raw materials of the phosphogypsum wallboard into a phosphogypsum wallboard material slurry. The PLC control system opens the discharge port 12, and the crane 3 runs to drive the mixing tank 1, and the mixing tank 1 moves to the top of the forming mold 2.

When the raw material slurry of the phosphogypsum wallboard is poured into the forming mold 2, the vibration of the vibrator 26 can make the raw material slurry of the phosphogypsum wallboard fill all the gap spaces in the forming mold 2, thereby preventing the manufactured phosphogypsum wallboard from being formed.

[0027] The specific implementation process is as follows:

[0028] The initial state of this device is that the single-pole double-throw switch 27 controls the hole column plate 62 and the base 64 on the wall panel through-hole device 6 to be in the power-on state, and the molding frame 21 on the molding mold 2 is in the power-off state. At this time, the hole column plate 62 made of electromagnet material is fixed on the base 64 by magnetic stable adsorption. The base 64 made of electromagnet material can stably adsorb the through-hole column 61, the hole column plate 62, and the hole column frame 63 into one. First, the raw materials of the phosphogypsum wallboard are injected into the mixing tank 1 through the conveyor 5, and the stirring propeller 11 in the mixing tank 1 stirs to mix the raw materials of the phosphogypsum wallboard evenly into phosphogypsum slurry. At this time, the single-pole double-throw switch 27 is switched to make the hole column plate 62 and the base 64 in the power-off state without magnetic adsorption, and the molding frame 21 is in the power-on state with magnetic adsorption, and the cylinder 65 in the wall panel through-hole device 6 is started to push the hole column plate 62, and the hole column frame 63 holds the through-hole column 61 to move, and finally the through-hole column 61 moves to pass through the frame door 23. The circular hole on the through-hole column 61 passes through the forming mold 2. At this time, the through-hole column 61 is separated from the hole column plate 62, and the through-hole column 61, the hole column frame 63 and the forming mold 2 are integrated. Then the crane 3 is started to lift the mixing tank 1 to move, the discharge port 12 of the mixing tank 1 is opened, and then the evenly mixed phosphogypsum slurry is injected into the forming mold 2, and the vibrator 26 is started. The vibrator 26 drives the forming mold 2 to vibrate, so that the raw material slurry of the phosphogypsum wallboard fills all the gap spaces in the forming mold 2. After 30 minutes, the phosphogypsum slurry condenses into a phosphogypsum wallboard, the wallboard through-hole device 6 is pushed out, the steel bar 25 on the forming frame 21 is removed, the frame door 23 is opened, and the formed phosphogypsum wallboard is taken out by a forklift. The entire production process of the phosphogypsum wallboard adopts a PLC control system linkage to realize intelligent automation. The through-hole device 6 can be made into a phosphogypsum wallboard with a through hole by cooperating with the forming mold 2. Such a phosphogypsum wallboard has a short air-drying time, which speeds up the manufacturing rate of the phosphogypsum wallboard and saves time and cost.
