Description

Technical Field

[0001] The utility model specifically relates to a feeding device for the production of spray - quick - setting rubber asphalt waterproof coating, belonging to the technical field of waterproof coating production. Background Technique

[0002] The main components of the spray - quick - setting rubber asphalt waterproof coating are composed of more than 2 kinds of high - performance modified emulsified rubber asphalt and chemical coagulation catalysts, and have a two - component structure with the characteristics of rapid initial solidification; some components in the existing spray - quick - setting rubber asphalt waterproof coating have a relatively high viscosity, and the feeding is rather cumbersome. For this reason, the Chinese patent authorization publication number: CN208230192U discloses a feeding device for the production of spray - quick - setting rubber asphalt waterproof coating, including a storage tank. A discharge pipe is arranged at the lower part of the storage tank, a mixing tank is arranged below the discharge pipe, a mixing motor is installed at the bottom of the mixing tank, and a mixing blade is connected to the output shaft of the mixing motor. This structure has a strong feeding and conveying capacity for viscous coatings, has a good heating and heat - preservation effect during the conveying process, effectively avoids the curing of the coating, and improves the product performance; however, the feeding path of this device is long, and due to the certain viscosity of the raw material components, during the feeding process of the weighed components, it is easy to cause a large deviation between the weighed weight of the feeding and the actual feeding amount due to scraping the wall in the middle, resulting in an imbalance in the coating ratio in the production kettle and affecting the product quality; in addition, due to the high viscosity of some components of the coating, the feeding is relatively slow, which is likely to affect the production time, and it is impossible to add each component to the production kettle at one time, and it is impossible to achieve the full - mixing reaction of each component of the coating, which is likely to affect the product quality. Content of the Utility Model

[0003] To solve the above problems, the utility model proposes a feeding device for the production of spray - quick - setting rubber asphalt waterproof coating, which can quickly add a sufficient amount of proportioned viscous components to the reaction kettle through heating and pressurization, and the viscous components can be synchronously mixed and reacted with other components to ensure the production quality of the spray - quick - setting rubber asphalt waterproof coating.

[0004] The feeding device for the production of spray - quick - setting rubber asphalt waterproof coating of the utility model includes:

[0005] A high - level storage tank, on the top of which a filling alarm is arranged; a slurry feeding pipe is arranged below the filling alarm of the high - level storage tank, and the slurry feeding pipe is connected to the storage tank through a slurry pump group;

[0006] A feeding tank, between which and the high - level storage tank a first group of electric control valves is arranged; a heating jacket is fixedly sleeved outside the feeding tank; the heating jacket is connected in series to a steam supply unit; the bottom of the feeding tank is connected to a second group of electric control valves; the second group of electric control valves is connected to the feeding port of the production kettle.

[0007] Rodless scraping unit, the rodless scraping unit includes a scraping motor fixed to the top of the feeding tank, and a bushing is fixed on the output shaft of the scraping motor; a scraping paddle is fixed on the outer wall of the bushing; the outer wall of the scraping paddle is attached to the inner wall of the feeding tank.

[0008] During operation, the viscous component is directly pumped into the high-level storage tank in a non-metering manner. The high-level storage tank is used as a buffer tank. Then, using the height difference, the stored material in the high-level storage tank is fed into the feeding tank; the feeding tank stores the metered components. Then, the components in the feeding tank are heated by the heating jacket and the rodless scraping unit, and the second electric control valve group is opened to quickly feed the components into the production kettle, and the feeding is more thorough; the inventory of the high-level storage tank is initially estimated by monitoring the opening times of the first electric control valve group. When the first electric control valve group is opened the set number of times, the slurry pump group starts the feeding replenishment action. During the replenishment process, when the filling alarm gives a full material alarm, the slurry pump group stops operating.

[0009] Further, the feeding tank is a metering tank; the viscous component is metered by volume, and the feeding tank is used as a metering tank; the first electric control valve group is opened until the feeding tank is full, and after closing the first electric control valve group, one metering of the viscous component is completed. During metering, since there is a scraping paddle in the feeding tank, the feeding tank needs to be pre-calibrated for metering.

[0010] Further, the first electric control valve group is a V-cone flow metering valve; the V-cone flow metering valve can monitor the weight of the viscous component entering the feeding tank in real time. After reaching the set weight, the V-cone flow metering valve is closed.

[0011] Further, the filling alarm includes a sliding cylinder attached to the upper part of the inner wall of the high-level storage tank. A sliding rod is fixed to the top of the sliding cylinder, and the sliding rod slides out of the high-level storage tank through a bearing; a limit detection plate is fixed to the sliding rod outside the high-level storage tank. A cylinder base is fixed to the high-level storage tank outside the sliding rod, and a convex pipe base is screwed inside the cylinder base; the sliding rod slides into the inner side of the protruding section of the pipe base, and a pressure induction switch is fixed to the bottom of the protruding section of the pipe base; the limit detection plate is arranged opposite to the pressure induction switch, and the pressure induction switch is connected to the controller of the whole machine control; during operation, after the first electric control valve group is opened the set number of times, the slurry pump group is started. The slurry pump group pumps the slurry through the slurry feeding pipe. The slurry component in the storage tank is pumped into the high-level storage tank through the slurry feeding pipe; the slurry component is continuously pumped into the high-level storage tank until the slurry component pushes up the sliding cylinder, so that the sliding rod slides upward along the bearing synchronously until the limit detection plate presses against the pressure induction switch. The pressure induction switch gives a signal to the controller, and the controller gives a signal to the slurry pump group, and the slurry pump group stops; until the first electric control valve group is triggered the set number of times again, the slurry pump group is started again for pumping.

[0012] Further, a tee joint is connected in series between the first electric control valve group and the feeding tank, and a check valve is connected to the third end of the tee joint; the input end of the check valve is connected to a pressure gas source through a third electric control valve group and a pneumatic tube; during operation, the pressure gas source provides pressurized gas, and the pressurized gas enters the tee joint through the third electric control valve group and the check valve, and the pressurized gas pressurizes and discharges the viscous component in the feeding tank out of the feeding tank.

[0013] Further, a check valve is connected in series between the high-level storage tank and the slurry feeding pipe; the slurry pump group continuously pumps the slurry into the slurry feeding pipe and injects it into the high-level storage tank through the check valve; when the slurry pump group stops, the top of the slurry feeding pipe can be closed through the check valve to prevent the viscous slurry from overflowing.

[0014] Compared with the prior art, the feeding device for the production of spray-applied rapid-set rubber asphalt waterproof coating of the present utility model performs quantitative metering at the entrance of the production kettle, and will not cause scraping wall loss of the viscous component due to too long feeding path. A feeding tank is arranged on the metering outlet side. By heating the outer wall of the feeding tank, the viscous component can be heated through heat conduction to reduce its viscosity, and the viscous component is pumped into the production kettle through pressurization. The feeding efficiency is high, and the heat received externally can be directly transferred to the production kettle, making the production more environmentally friendly; the heated feeding tank can heat the viscous component adhering to the wall, making it flow by itself, reducing the amount of wall adhesion, and scraping the remaining wall-adhering component through the scraping paddle. Since the scraping paddle is in a rotating state and fits the feeding tank, it can be synchronously heated by the feeding tank, so that the coating component can quickly drip into the production kettle; the viscous component can be mixed and reacted with other components synchronously to ensure the production quality of the spray-applied rapid-set rubber asphalt waterproof coating.

[0020] Example:

[0021] As Figures 1 to 4 The feeding device for the production of spray-applied rapid-setting rubber asphalt waterproof coating shown in the figure includes:

[0022] A high-level storage tank 1, on the top of which a filling alarm is arranged; a slurry feeding pipe 2 is arranged below the filling alarm of the high-level storage tank 1, and the slurry feeding pipe 2 is connected to the storage tank through a slurry pump group;

[0023] A feeding tank 3, between which and the high-level storage tank 1 a first electric control valve group 4 is arranged; a heating jacket 5 is fixedly sleeved outside the feeding tank 3; the heating jacket 5 is connected in series to a steam supply unit; the bottom of the feeding tank 3 is connected to a second electric control valve group 6; the second electric control valve group 6 is connected to the feeding port of the production kettle;

[0024] A rodless scraping unit, which includes a scraping motor 7 fixed on the top of the feeding tank 3, a shaft sleeve 8 is fixed on the output shaft of the scraping motor 7; a scraping paddle 9 is fixed on the outer wall of the shaft sleeve 8; the outer wall of the scraping paddle 9 is attached to the inner wall of the feeding tank 3.

[0025] During operation, the viscous component is directly pumped into the high-level storage tank 1 in a non-metering manner. Using the high-level storage tank 1 as a buffer tank, then, by using the height difference, the material stored in the high-level storage tank 1 is sent into the feeding tank 3; the components that have completed metering are stored in the feeding tank 3, and then, the components in the feeding tank 3 are heated through the heating jacket 5 and the rodless scraping unit, and the second electric control valve group 6 is opened to quickly send the components into the production kettle, and the feeding is more thorough; the stock volume of the high-level storage tank 1 is initially estimated by monitoring the opening times of the first electric control valve group 4. When the first electric control valve group 4 is opened a set number of times, the slurry pump group starts the feeding replenishment operation. During the replenishment process, when the filling alarm gives a full material alarm, the slurry pump group stops operating.

[0026] The feeding tank 3 is a metering tank; the viscous component is metered by volume, and the feeding tank 3 is used as a metering tank; the first electric control valve group 4 is opened until the feeding tank 3 is filled, and after the first electric control valve group 4 is closed, one-time metering of the viscous component is completed. During metering, since the scraping paddle 9 is arranged in the feeding tank 3, therefore, the feeding tank 3 needs to be pre-calibrated for metering.

[0027] The first electric control valve group 4 is a V-cone flow metering valve; the weight of the viscous component entering the feeding tank 3 can be monitored in real time through the V-cone flow metering valve, and after reaching the set weight, the V-cone flow metering valve is closed.

[0028] The filling alarm includes a sliding cylinder 10 that fits against the upper inner wall of the high-level storage tank 1. A sliding rod 11 is fixed to the top of the sliding cylinder 10, and the sliding rod 11 slides out of the high-level storage tank 1 through a bearing. A limit detection plate 12 is fixed to the sliding rod 11 outside the high-level storage tank 1. A cylinder base 13 is fixed to the high-level storage tank 1 outside the sliding rod 11, and a convex pipe base 14 is rotatably connected to the inner side of the cylinder base 13. The sliding rod 11 slides into the inner side of the protruding section of the pipe base 14, and a pressure induction switch 15 is fixed to the bottom of the protruding section of the pipe base 14. The limit detection plate 12 is arranged opposite to the pressure induction switch 15, and the pressure induction switch 15 is connected to the controller of the whole machine control. During operation, after the first electric control valve group 4 is opened a set number of times, the slurry pump group is started. The slurry pump group pumps the slurry through the slurry feed pipe 2, and the slurry components in the storage tank are pumped into the high-level storage tank 1 through the slurry feed pipe 2. The slurry components are continuously pumped into the high-level storage tank 1 until the slurry components push up the sliding cylinder 10, so that the sliding rod 11 slides upward along the bearing synchronously until the limit detection plate 12 presses against the pressure induction switch 15. The pressure induction switch 15 gives a signal to the controller, and the controller gives a signal to the slurry pump group, and the slurry pump group stops. Until the first electric control valve group 4 is triggered again a set number of times, the slurry pump group is started again to pump the material.

[0029] A tee 16 is connected in series between the first electric control valve group 4 and the feeding tank 3, and a check valve is connected to the third end of the tee 16. The input end of the check valve is connected in series to the pressure air source through the third electric control valve group and the air pressure pipe 17. During operation, the pressure air source provides pressurized gas. The pressurized gas enters the tee 16 through the third electric control valve group and the check valve, and the pressurized gas pressurizes and discharges the viscous components in the feeding tank 3.

[0030] A check valve is connected in series between the high-level storage tank 1 and the slurry feed pipe 2. The slurry pump group continuously pumps the slurry into the slurry feed pipe 2 and pumps it into the high-level storage tank 1 through the check valve. When the slurry pump group stops, the top of the slurry feed pipe 2 can be closed through the check valve to prevent the viscous slurry from overflowing.

[0031] When the feeding tank 3 is heated, it can heat the viscous components adhering to the wall, making them flow by themselves, reducing the amount of adhesion to the wall, and scraping the remaining wall-adhering components by the scraping paddle 9. Since the scraping paddle 9 is in a rotating state and fits against the feeding tank 3, it can be heated synchronously by the feeding tank 3, so that the coating components can quickly drip into the production kettle.
