Description

Powder coating spraying device and circulating collection system for spraying waste materials

Technical Field

The present invention relates to powder coating equipment, and more particularly, to a recycling collection system for coating waste, and to a powder coating material coating apparatus having the same.

Background

For part of aluminum alloy sheet pieces, because the aluminum alloy sheet pieces need to be exposed to outdoor environment, the requirements on the stability of the surface properties and the service life of the whole aluminum alloy sheet pieces are long; the service life of the board as its outer shell material is usually accompanied by the entire life cycle of the overall product. In order to improve the performance of the aluminum alloy sheet, a powder spraying method is usually adopted to spray powder on the outer layer, and a spraying protective layer is formed on the outer layer to improve the surface performance of the aluminum alloy sheet.

Powder spraying is to spray powder coating on the surface of a workpiece by using powder spraying equipment (an electrostatic plastic spraying machine), and powder can be uniformly adsorbed on the surface of the workpiece under the action of static electricity to form a powdery coating; the powdery coating is baked at high temperature, leveled and cured to become final coatings with different effects (different kinds of effects of the powdery coating). The spraying effect of the powder spraying is superior to that of a paint spraying process in the aspects of mechanical strength, adhesive force, corrosion resistance, aging resistance and the like, and the surface of the aluminum alloy is processed by the processing process, so that the surface performance of the aluminum alloy can be improved, and the service life of the aluminum alloy can be prolonged.

In the powder spraying process, powdery particles are sprayed out through a spraying machine to form coating similar to atomization on the surface of a workpiece, but only a small amount of the powder particles are attached to the surface of a workpiece product, most of the powder particles cannot be adsorbed, and the powder particles are processed and discharged into clean water to become waste. In a relatively advanced treatment process, the spraying sediment in the wastewater can be collected by adopting a filtering and collecting mode, and then the sediment can be recycled. And a large amount of water is doped in the recovered precipitation slag, and the precipitation slag can be obtained by extruding water and drying, so that the residual value of the powder slag is recovered.

However, when the powder-sprayed granulated slag is collected by filtration, it is difficult to separate the granulated slag by filtration because the particle size of the powder particles is small. If the filtering material with larger filtering holes is adopted for processing, a large part of granular slag can leak out, and the normal filtering effect cannot be achieved. If a fine and dense filtering material is adopted, although the filtering material can block granular slag, the filtering holes are small, the efficiency of filtering and treating wastewater is low, and the granular slag easily blocks the filtering holes, so that the filtering material is blocked, and the normal filtering is influenced.

In order to solve the problems, the conventional method is to adopt a filtering material with a small filtering pore diameter and dredge the filtering material by adopting a timed backwashing mode so as to prevent the filtering material from being completely blocked by granular slag; although the granular slag can be separated only by this method, the separation efficiency is still low.

Therefore, a new solution is needed to solve this problem.

The piston 13 has an up-down moving stroke in the lifting process, the uppermost end of the stroke can reach the tapered groove 10, and the lowermost end of the stroke extends into the middle lower part of the slag discharge pipe 11. Through the continuous sizing adjustment of the piston 13, the sediment at the upper end of the sediment discharge pipe 11 can be pumped downwards, and further the sediment can be pumped. After the piston 13 moves upwards, the slag discharge pipe 11 can be opened, the gathered flocculent precipitated slag flows downwards to enter the slag discharge pipe 11, then the precipitated slag descends through the piston 13 and can be pressed downwards to be pumped, impurities in the slag discharge pipe 11 are discharged into the slag discharge main pipe 12, the gathered precipitated slag is discharged, the gathered precipitated slag is facilitated to be discharged, and the gathered precipitated slag is introduced into the slag discharge main pipe 12 and can be discharged.

An extension pipe 16 is fixedly connected to the upper end of the slag discharging pipe 11, the extension pipe 16 and the slag discharging pipe 11 are coaxially arranged, the pipe diameters are consistent, and the slag discharging pipe 11 extends upwards into the conical groove 10 to form an upwards extending structure of the slag discharging pipe 11. A plurality of slag leaking ports 17 are formed in the outer side of the lower end of the extension pipe 16, and generally, two slag leaking ports 17 can be symmetrically formed, or three to four slag leaking ports 17 are circumferentially distributed. The slag leakage port 17 is a long strip-shaped structure which runs up and down and penetrates through the inner wall and the outer wall of the extension pipe 16, and the lower end edge of the slag leakage port extends to the inner wall of the conical groove 10, so that impurities sliding down from the side wall of the conical groove 10 can directly enter the slag discharge pipe 11 along the slag leakage port 17.

During the upward movement, the piston 13 can extend into the extension pipe 16 and move to the upper side position of the slag leakage opening 17, and a guiding effect can be formed on the piston 13 along the pipe. And after the piston 13 enters the upper position of the extension pipe 16, an inward suction force is formed at the position of the slag leakage opening 17, so that the effect of gasket slag accumulation at the bottom position of the conical groove 10 can be increased to a certain extent.

As shown in FIG. 2, the confluence device has several groups, and corresponds to the slag leakage opening 17 on the periphery of the slag discharge pipe 11. Specifically, the slag converging device comprises an upper guide wheel 19, a lower guide wheel 18, a side guide wheel 20 and an annular converging belt 21, wherein the upper guide wheel 19 is rotatably installed at the upper end position of the extension pipe 16, the lower guide wheel 18 is rotatably installed at the inner side of the slag leakage opening 17, the side guide wheel 20 is rotatably connected with the outer side position of the extension pipe 16, and three guide wheels form a three-point-shaped supporting structure. The converging belt 21 surrounds the upper guide wheel 19, the lower guide wheel 18 and the side guide wheel 20 to form a belt connecting structure, the converging belt 21 forms a triangular distribution structure after installation, and when the converging belt 21 moves around, flocculent slag near the surface of the converging belt 21 is driven to flow, so that water flow and precipitated slag can be promoted to be gathered towards the center of the bottom of the conical groove 10, and the precipitated slag can conveniently enter the slag leakage opening 17.

The slag collecting device can be driven by a single motor or a mode of linkage with the piston 13, and further, a collecting belt 21 outside the slag collecting device is driven. For example, when the motor is used for driving, the output shaft of the motor is connected with one of the guide wheels, the motor can drive the confluence belt to rotate, the confluence belt 21 at the peripheral position of the extension pipe 16 moves downwards, and then the confluence belt 21 can be driven to form a downward pushing promoting effect on water flow in the tapered groove 10, so that the sedimentation slag is intensified to be converged.

As shown in fig. 3, in order to increase the propelling movement effect of the confluence belt 21 to water flow, the outward side of the confluence belt 21 is provided with the slag removing sheet 26, the slag removing sheet 26 is uniformly distributed on the confluence belt 21 to form a surrounding paddle-shaped structure, and in the operation process of the confluence belt 21, the water flow on the periphery of the confluence belt 21 can be aggravated to be gathered towards the middle position, so that the gathering effect on the precipitated slag is promoted.

The slag collecting device can also be in linkage fit with the piston 13, specifically, as shown in fig. 2, a guide rod 22 is fixedly connected to the upper end of the piston 13, the guide rod 22 extends upwards into the extension pipe 16, and the guide rod 22 and the collecting belt 21 at the inner side of the extension pipe 16 are fixedly connected through a connecting block 23. In the process of adjusting the elevation of the piston 13, the connecting block 23 can drive the reflux belt at the connecting position to move up and down, and further drive the whole converging belt 21 to move circularly.

When the piston 13 moves upwards, the guide rod 22 at the upper end of the piston 13 drives the confluence belt 21 to rotate, the confluence belt 21 extending out of the periphery of the extension pipe 16 moves downwards, and at the moment, the confluence belt 21 drives nearby sediments to be gathered near the slag leakage opening 17; the piston 13 continuously moves up and down, enters the extension pipe 16 and moves to the upper side of the slag leakage opening 17, at the moment, the opening of the slag discharging pipe 11 is opened, and impurities in the slag leakage opening 17 can flow downwards towards the slag discharging pipe 11 and enter the slag discharging pipe 11; then the piston 13 will move downwards and enter the slag discharge pipe 11, and the piston 13 forms a pump pressure form in the slag discharge pipe 11 to extrude the precipitated slag into the slag discharge main pipe 12, so as to realize the function of auxiliary discharge of the precipitated slag.

Further, the slag removing pieces 26 on the periphery of the bus bar 21 can be redesigned, the slag removing effect is improved, and adverse effects caused in the reversing process of the bus bar 21 are avoided. Specifically, this group's cinder strip 26 one end extends to the outside and hangs in the air, and articulated connection between the other end and the confluence belt 21 forms wobbling articulated state between the two, and when confluence belt 21 forward encircles the in-process, group's cinder strip 26 will be opened, then stirs downwards through can be to the sediment near confluence belt 21. When the confluence belt 21 rotates reversely, the confluence belt 21 moves upwards outside the extension pipe 16, and the slag-removing pieces 26 are folded towards the confluence belt 21, so that the contact efficiency with the external environment is reduced, and the stirring of water flow and sediment is reduced.

As shown in fig. 4, a hinge end 261 is fixed on the slag removing sheet 26, a hinge seat 262 is fixed on the bus bar 21, the hinge seat 262 and the hinge end 261 are hinged to each other, and a structure capable of being adjusted in a swinging mode is formed between the hinge seat 262 and the hinge end 261. A movable stop 263 is fixedly connected to the periphery of the hinged end 261, and the movable stop can swing and swing along with the swinging of the hinged end 261; the fixed stop 264 is fixedly connected to the corresponding position of the hinged seat 262, the fixed stop 264 and the movable stop 263 are mutually matched, and the upward swinging angle of the slag removing sheet 26 can be limited by the limit of the abutting resistance of the fixed stop 264 and the movable stop 263 in the rotating process.

In the downward surrounding movement process of the bus bar 21 at the outer side, the slag poking sheet 26 is opened by the resistance of water flow and is pressed and limited by the fixed stop 264 and the movable stop 263; during the upward circulating movement of the bus bar 21 on the outer side, the slag removing pieces 26 are folded toward the bus bar 21 by the water flow resistance. If the position shown in fig. 4 is the maximum opening angle of the slag-removing piece 26, the downward swing can realize the furling.

As shown in FIG. 2, the bus bar 21 passes around the position between the side guide wheel 20 and the lower guide wheel 18 to form an inclined section 24, a gap 25 is formed between the inclined section 24 and the side wall of the conical groove 10, and during the rotation of the bus bar 21, the sediment in the gap 25 is mainly driven into the slag leakage opening 17.

The gap 25 is gradually reduced towards the slag leakage opening 17 because the inclined direction of the inclined section 24 is inclined at a larger angle, and the inclination of the bottom of the conical groove 10 is larger and smaller. The clearance 25 gradually reduces, so that the sediment inside the clearance 25 is continuously converged to form a good polymerization effect, and in the process of converging the sediment, the mixed water correspondingly flows out from the gap, and the solid-liquid ratio of the sediment is improved.

Furthermore, the inclined state of the inclined section 24 can be set to be in an adjustable structure, the distance between the side guide wheel 20 and the extension pipe 16 can be adjusted, and the size and the taper of the gap 25 can be adjusted by adjusting the position of the side guide wheel 20 and further changing the gap 25 between the inclined section 24 on the lower side of the side guide wheel 20 and the bottom of the conical groove 10.

Specifically, as shown in fig. 5, the side guide wheel 20 is connected with the extension pipe 16 through a telescopic rod 27, a fixed end of the telescopic rod 27 is fixed outside the extension pipe 16, and the telescopic rod 27 can be a cylinder, a hydraulic cylinder or an electric push rod and has a telescopic movable end, and the telescopic movable end can be extended and retracted in the horizontal direction through adjustment. The side guide wheel 20 is rotatably mounted on the movable end of the telescopic rod 27, and the position of the confluence belt 21 can be adjusted through adjustment. By moving the side guide 20 outward, the upper opening of the gap 25 can be reduced, and the bus bar 21 of the inclined segment 24 can be brought closer to the side wall of the tapered groove 10, thereby improving the effect of guiding the impurities in the gap 25. By moving the side guide 20 inward, the opening on the upper side of the gap 25 can be enlarged, so that the upper side position of the inclined section 24 has a larger space, the sediment can flow into the gap 25 more easily, and the amount of the sediment entering the gap 25 is increased. During use, the side guide wheel 20 can move and adjust towards the outer side during the upward movement of the piston 13; and during the descending process of the piston 13, the side guide wheel 20 moves towards the inner side direction, so as to improve the accumulation and confluence effect of the sediment in the space of the gap 25.

The upper guide wheel 19 is rotatably connected to an adjusting seat 31, and the adjusting seat 31 can adopt a structure of up-and-down floating adjustment so as to be suitable for adjusting the confluence belt 21. The lower side of the adjusting seat 31 and the extension pipe 16 are elastically supported by a spring 30, and a slide rod 29 is fixedly connected to the lower side of the adjusting seat 31, and the slide rod 29 is in a vertical state and plays a role of guiding.
