Description

Technical Field

[0001] The invention belongs to the technical field of waterproof spraying, and specifically refers to a waterproof spraying device used for preventing basement leakage. Background Art

[0002] Spraying is a commonly used coating technology. The working principle of spraying is mainly based on the fact that the paint is pressed or sucked out of the container by external force (such as compressed air or a high-pressure pump), and dispersed into uniform and fine droplets through a spray gun or a disc atomizer, and finally applied to the surface of the object to be coated.

[0003] The existing waterproof spraying device using the spraying method has the following problems:

[0004] During the spraying process of the existing waterproof spray device, since the paint is atomized at high pressure and sprayed onto the base surface, part of the paint will float in the air. The paint floating in the air will move irregularly, thereby causing large-scale pollution during the spraying operation. It is impossible to select a spray pipe suitable for the spraying operation according to the on-site wind speed of the spraying operation. Therefore, it is unable to meet the existing demand for the use of waterproof spray devices. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present solution provides a waterproof spraying device for basement leakage prevention, which can select a spray pipe suitable for the spraying operation according to the on-site wind speed of the spraying operation, thereby reducing the probability of the atomized paint drifting irregularly with the air and polluting the environment over a large area.

[0006] The technical scheme adopted in this scheme is as follows: This scheme proposes a waterproof spraying device for basement leakage prevention, including a spraying vehicle, a spraying table, a paint box, a thermal spraying mechanism and a negative suction anti-drifting mechanism. The spraying table is arranged on the upper wall of the spraying vehicle, the paint box is arranged on the upper wall of the spraying vehicle on one side of the spraying vehicle, the thermal spraying mechanism is arranged on the spraying table, and the negative suction anti-drifting mechanism is arranged on the thermal spraying mechanism.

The heating tank is arranged on the inner wall of the spraying station, and the heating tank is arranged through. The heating metal rod is arranged on the inner wall of the heating tank. The heating coil is symmetrically arranged on the inner walls on both sides of the heating tank outside the heating metal rod. Multiple groups of the heating copper rods penetrate the side walls of the heating metal rods arranged between the heating coils in the paint box; the liquid extraction mechanism includes a liquid extraction pump and a liquid infusion tube. Multiple groups of the liquid extraction pumps are arranged on the side of the paint box away from the spraying station. The liquid extraction end of the liquid extraction pump penetrates the inside of the paint box. The liquid infusion tube is arranged at the discharge of the liquid extraction pump. Liquid end; the coating mechanism includes a spray barrel, a spray gun, a normal-pressure atomization pipe, a long nozzle, a pipe clamp and a branch nozzle. Multiple groups of the spray barrels are arranged on the upper wall of the spray platform. The spray barrel is arranged through, and the spray gun is arranged inside the spray barrel. The end of the infusion pipe away from the liquid pump is connected to the power input end of the spray gun, and the normal-pressure atomization pipe is arranged at the power output end of the spray gun. The branch nozzle is arranged on the bottom wall of the spray vehicle away from the spray platform, and the end of the normal-pressure atomization pipe away from the spray gun is connected to the side wall of the branch nozzle. The long nozzle is connected to the bottom wall of the branch nozzle, and the pipe clamp is arranged between the bottom wall of the spray vehicle and the normal-pressure atomization pipe.

[0008] When in use, the heating coil is energized to induction heat the heating metal rod. The temperature of the heating metal rod increases and heats the heating copper rod. The heating copper rod heats the paint inside the paint box. The liquid extraction pump in the middle of the side wall of the paint box extracts the heated waterproof paint inside through the liquid extraction end. The waterproof paint is transported to the inside of the spray gun through the infusion tube. The spray gun atomizes the waterproof paint with high pressure and transports it to the inside of the normal-pressure atomization tube. The normal-pressure atomization tube sprays the atomized waterproof paint onto the base surface of the large basement through the branch nozzle using a long nozzle, thereby completing the waterproof spraying operation on the base surface of the large basement.

[0009] Preferably, the collecting mechanism comprises a collecting platform, a collecting cylinder, a filter, a driving tube, a vortex tube, a one-way valve, a negative pressure adsorption tube, a negative pressure port, a negative pressure atomizing tube and a wind speed sensor; the collecting platform is arranged on the upper wall of the spraying cylinder; the collecting cylinder penetrates the inner wall of the collecting platform at one end away from the infusion tube; the filter is arranged on the inner wall of the collecting cylinder; the negative pressure atomizing tube is arranged at the power output end of the spray gun on both sides of the normal pressure atomizing tube; the vortex tube is connected between the negative pressure atomizing tube and the branch nozzle; the one-way valve is connected to the side wall of the narrow tube of the vortex tube; the driving tube is connected between the one-way valve and the side walls of the collecting cylinder at both ends of the spraying platform The negative pressure adsorption tube is connected to the side wall of the collecting tube between the driving tubes, and the end of the negative pressure adsorption tube away from the collecting tube is located below the spraying vehicle. The negative pressure port is arranged at the end of the negative pressure adsorption tube close to the bottom wall of the spraying vehicle, and the wind speed sensor is symmetrically arranged on both sides of the spraying platform; the curing mechanism includes a curing frame, a curing coil and a curing metal rod, the curing frame is arranged at the end of the infusion tube close to the spraying platform, the curing metal rod is arranged between the collecting platform and the curing frame, the end of the curing metal rod away from the curing frame passes through the collecting platform and is arranged inside the collecting tube, and the curing coil is arranged between the curing frame and the collecting platform on the outside of the curing metal rod.

[0010] When in use, the wind speed sensor monitors the ventilation wind speed inside the large basement. When the ventilation wind speed inside the large basement monitored by the wind speed sensor exceeds the wind speed specified by the operator, the liquid extraction pump in the middle of the side wall of the paint box stops transporting waterproof paint to the spray gun in the middle of the spray station, and the liquid extraction pumps at both ends of the side wall of the paint box extract the heated waterproof paint inside the paint box through the liquid extraction end, and the waterproof paint enters the spray guns at both ends of the spray station through the infusion tube. The spray guns at both ends of the spray station atomize the waterproof paint with high pressure and discharge it into the negative pressure atomization pipe. The negative pressure atomization pipe transports the atomized waterproof paint to the branch spray pipe through the vortex pipe, and the branch spray pipe sprays the waterproof paint on the base surface of the large basement through the long nozzle.

[0011] Specifically, a controller is provided on the side wall of the spraying station.

[0012] Wherein, the controller is electrically connected to the heating coil, the liquid extraction pump, the spray gun, the wind speed sensor and the curing coil respectively.

[0013] Preferably, the model of the controller is HAD-SC200.

[0014] Furthermore, the model of the wind speed sensor is FC-2A1.

[0015] The beneficial effects achieved by adopting the above structure are as follows:

[0016] Compared with the prior art, this solution adopts a combination of a wind speed monitoring structure and a negative pressure adsorption structure. Through the thermal spraying mechanism and the negative suction anti-drifting mechanism, under the coordinated use of the heating mechanism, the liquid extraction mechanism, the coating mechanism, the collecting mechanism and the curing mechanism, on the one hand, it can overcome the influence of external wind force, ensure the spraying effect of the atomized waterproof coating, and reduce the probability of the atomized waterproof coating drifting with the air during the spraying process. On the other hand, through the multi-channel setting of the narrow tube, the spraying operation on the base surface of a large basement can be completed under the condition of ensuring the amount of coating sprayed. The waterproof coating is transported to the inside of the spray gun through an infusion tube. The spray gun atomizes the waterproof coating under high pressure and then transports it to the inside of the normal-pressure atomization tube. The normal-pressure atomization tube uses a long nozzle through a branch nozzle to spray the atomized waterproof coating onto the base surface of the large basement.

[0036] A controller 34 is disposed on the side wall of the spraying station 2 .

[0037] The controller 34 is electrically connected to the heating coil 7 , the liquid pump 11 , the spray gun 15 , the wind speed sensor 36 and the curing coil 32 , respectively.

[0038] The model of the controller 34 is HAD-SC200.

[0039] The model of the wind speed sensor 36 is FC-2A1.

[0040] In specific use, in Embodiment 1, the waterproof coating to be used is injected into the coating box 3, and the spraying vehicle 1 is pushed to move to the base surface of the large basement, and the waterproof coating inside the coating box 3 is heated. Heating can reduce the viscosity of the waterproof coating, making it easier to spray, and improve the fluidity of the coating, which helps to form a more uniform and dense waterproof layer;

[0041] The controller 34 controls the heating coil 7 to start, and the heating coil 7 is energized to perform induction heating on the heating metal rod 8. The temperature of the heating metal rod 8 increases to heat the heating copper rod 9, and the heating copper rod 9 heats the paint inside the paint box 3. Subsequently, the controller 34 controls the liquid extraction pump 11 in the middle of the side wall of the paint box 3 to start, and the liquid extraction pump 11 extracts the heated waterproof paint inside the paint box 3 through the liquid extraction end, and the waterproof paint is transported to the inside of the spray gun 15 through the infusion tube 12. The controller 34 controls the spray gun 15 to start, and the spray gun 15 performs high-pressure atomization on the waterproof paint and then transports it to the inside of the normal-pressure atomization tube 16. The normal-pressure atomization tube 16 sprays the atomized waterproof paint onto the base surface of the large basement through the branch nozzle 35 using the long nozzle 17, and pushes the spraying vehicle 1 to move along the base surface of the large basement, thereby completing the waterproof spraying operation on the base surface of the large basement;

[0042] Embodiment 2: This embodiment is based on the above embodiment. When spraying inside a large basement, in order to ensure that the concentration of volatile organic compounds inside the large basement does not exceed the standard and affect the safety of the operators, the ventilation duct inside the large basement is usually opened to generate a certain amount of air flow inside the large basement. The waterproof coating is atomized by high pressure and sprayed onto the base surface. Part of the waterproof coating will float in the air with the gas flow, thereby causing the pollutants generated by the spraying operation to spread and pollute the environment.

[0043] The controller 34 controls the wind speed sensor 36 to start, and the wind speed sensor 36 monitors the ventilation wind speed inside the large basement. When the ventilation wind speed inside the large basement monitored by the wind speed sensor 36 exceeds the wind speed specified by the operator, the controller 34 controls the liquid extraction pump 11 in the middle of the side wall of the paint box 3 to stop conveying the waterproof coating to the spray gun 15 in the middle of the spraying station 2. At the same time, the controller 34 controls the liquid extraction pumps 11 at both ends of the side wall of the paint box 3 to extract the heated waterproof coating inside the paint box 3 through the liquid extraction end, and the waterproof coating enters the spray gun 15 at both ends of the spraying station 2 through the infusion tube 12. The spray guns 15 at both ends of the spraying station 2 atomize the waterproof coating with high pressure and discharge it into the negative pressure atomization pipe 29. The negative pressure atomization pipe 29 conveys the atomized waterproof coating to the inside of the branch nozzle 35 through the vortex tube 25. The branch nozzle 35 sprays the waterproof coating on the base surface of the large basement through the long nozzle 17.

[0044] When the ventilation wind speed inside the basement monitored by the wind speed sensor 36 is less than the operator's requirement, only one set of liquid extraction pumps 11 on the side wall of the paint box 3 is in operation. When the ventilation wind speed inside the basement monitored by the wind speed sensor 36 is greater than the operator's requirement, four sets of liquid extraction pumps 11 on the side wall of the paint box 3 are in operation, thereby ensuring that the spraying amount after changing the pipeline spraying is consistent.

[0045] When the atomized paint flows through the narrow tube of the vortex tube 25, negative pressure adsorption force is generated, and the atomized paint that deviates from the spraying track is absorbed by the negative pressure port 28 arranged around the long nozzle 17. The atomized paint enters the negative pressure adsorption tube 27 through the negative pressure port 28. The negative pressure adsorption tube 27 transports the scattered atomized paint to the inside of the collection tube 22 for filtering. The atomized paint entering the collection tube 22 is filtered by the filter screen 23 and then discharged into the driving tube 24.

[0046] The controller 34 controls the curing coil 32 to be energized, and the curing coil 32 is energized to induction heat the curing metal rod 33. The end of the curing metal rod 33 away from the curing coil 32 is located inside the collecting tube 22, and the curing metal rod 33 heats the inside of the collecting tube 22. After the temperature inside the collecting tube 22 rises, the atomized paint entering the inside is cured, thereby preventing the atomized paint containing dust from flowing back and being sprayed onto the base surface. A heat insulation coating is pre-coated on the outer side of one end of the driving tube 24 close to the curing coil 32, and the filtered air inside the driving tube 24 flows back to the inside of the vortex tube 25 through the one-way valve 26, completing the spraying operation on the base surface of the basement; the above operation can be repeated the next time it is used.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
