Abstract
Description
Technical Field
[0001] This disclosure relates to the field of spraying equipment technology, and in particular to a paraffin waterproofing dispersant spraying system. Background Technology
[0002] OSB / FOSB boards are a commonly used material in furniture boards. The waxing or waterproofing dispersant application process is completed in a roller mixer. Traditionally, a high-speed atomizing disc is used to atomize the paraffin wax and waterproofing dispersant. However, while atomizing discs are effective for liquids with good flowability and low viscosity, reliable atomization is difficult to guarantee for liquids like paraffin wax or waterproofing dispersants that easily solidify at low temperatures. This is especially problematic when applied in a low-temperature environment within a roller mixer. Currently, no reliable atomization method has been found to replace the atomizing disc method, so current paraffin wax waterproofing fans all use the atomizing disc method. This results in issues such as uneven paraffin wax application leading to wax spots, inadequate localized waterproofing, and high dosages of wax or waterproofing agent in the finished board.

[0027] Example
[0028] like Figure 1-2 As shown, this embodiment provides a paraffin waterproofing dispersant spraying system, including: a dispersant storage tank 60, a collection storage tank 30, a hot water storage tank 5, a first feed pump 90, and a spraying device. The spraying device includes a spraying diversion pipe 1 and a plurality of spray guns 176 connected to the spraying diversion pipe 1. The input end of the first feed pump 90 is connected to the output ends of the dispersant storage tank 60 and the hot water storage tank 5, respectively. The output end of the first feed pump 90 is connected to a spraying pipe 111. The spraying pipe 111 is connected to one end of the spraying diversion pipe 1, and the other end of the spraying diversion pipe 1 is connected to a return pipe. The return pipe 112 is connected to the input ends of the dispersant storage tank 60 and the collection tank 30 respectively. The output end of the collection tank 30 is connected to the dispersant storage tank 60 through the second feed pump 49. The spray pipe 111, the spray diversion pipe 1 and the return pipe 112 are fitted with heating outer sleeves 200. The output end of the hot water storage tank 5 is connected to a heating circulation pipe 201. The heating circulation pipe 201 passes through multiple heating outer sleeves 200 in sequence and then connects to the input end of the hot water storage tank 5 to form a circulation. A hot water circulation pump 170 is installed on the heating circulation pipe 201.
[0029] In this embodiment, the waterproof dispersant in the dispersant storage tank 60 is delivered to the spraying diversion pipe 1 via the first feed pump 90. The spray gun 176 is opened, and the waterproof dispersant is sprayed from the spray gun 176 to spray the board. The remaining waterproof dispersant continues to flow back to the collection tank 30 via the return pipe 112. Both the collection tank 30 and the dispersant storage tank 60 are equipped with level sensors. When the level in the collection tank 30 reaches a designated point, or the level in the dispersant storage tank 60 drops to a designated point, the second feed pump 49 delivers the waterproof dispersant from the collection tank 30 to the dispersant storage tank 60. Unused waterproof dispersant is reused. During spraying, hot water in the hot water storage tank 5 is pumped into the heating jacket 200 by the hot water circulation pump 170. The hot water in the heating jacket 200 exchanges heat with the waterproof dispersant in the spraying pipe 111, the spraying diversion pipe 1, and the return pipe 112, heating and keeping the waterproof dispersant warm. Finally, the hot water is circulated back to the hot water storage tank 5. Furthermore, the dispersant storage tank 60, the collection tank 30, and the hot water storage tank 5 are all equipped with heating coils, which are heated by passing hot oil through them, so that the hot water and waterproof dispersant inside the system can be maintained within a certain temperature range.
[0030] Furthermore, a proportional regulating valve 32, a safety protection valve 51, and a pressure regulating valve 83 are respectively installed between the return pipe 112 and the spraying pipe 111. The pressure of the waterproof dispersant in the pipe is adjusted by the proportional regulating valve 32, the safety protection valve 51, and the pressure regulating valve 83 to achieve constant pressure control of the system, which is generally set at 5-8 Bar.
[0031] Furthermore, a filter 110 is installed on the spraying pipe 111 between the first feed pump 90 and the spraying diversion pipe 1. The filter 110 filters out the unemulsified dispersant, thereby improving the spraying effect.
[0032] Furthermore, an inlet valve 7 is provided between the first feed pump 90 and the dispersant storage tank 60, and a water inlet valve 8 is provided between the first feed pump 90 and the hot water storage tank 5. The input end of the first feed pump 90 is connected to the dispersant storage tank 60 and the hot water storage tank 5 respectively. By changing the on / off state of the inlet valve 7 and the water inlet valve 8, the pump can be switched to spraying or cleaning operation. When the inlet valve 7 is open and the water inlet valve 8 is closed, the waterproof dispersant is supplied to the spraying pipeline 111 for spraying; when the inlet valve 7 is closed and the water inlet valve 8 is open, hot water is supplied to the spraying pipeline 111 for cleaning.
[0033] Furthermore, a spray return valve 18 is installed in the return pipe 112 between the dispersant storage tank 60 and the collection tank 30. To meet the requirements of short-term operation such as equipment pause or temporary shutdown, the equipment is also equipped with circulating heating control. After the equipment switches to circulating heating control, the first feed pump 90 runs, the spray return valve 18 is opened, and all spray guns 176 on the spray diversion pipe 1 are closed. Then, the waterproof dispersant flows in the first feed pump 90, filter 110, spray pipe 111, spray diversion pipe 1, and return pipe 112, and returns to the dispersant storage tank 60, completing the flow of the waterproof dispersant in the pipe and solving the solidification problem caused by the waterproof dispersant not flowing.
[0034] Furthermore, a mass flow meter 81 is installed on the spraying pipe 111, and a feed valve 70 and an isolation valve 71 are respectively installed at both ends of the spraying pipe 111 located at the mass flow meter 81. The flow rate of the spray gun 176 is controlled in a closed loop by controlling the opening value of the spray gun 176 and monitoring it through the mass flow meter 81.
[0035] Furthermore, a cleaning pump 131 is connected to the output end of the hot water storage tank 5, and the output end of the cleaning pump 131 is connected to the spraying pipe 111. A hot water inlet valve 8 is provided between the cleaning pump 131 and the spraying pipe 111. During the cleaning stage of the spray gun 176, the cleaning pump 131 and the hot water inlet valve 8 are turned on, the spray gun 176 is turned on, and the return valve 84 of the collection tank 30 and the spray return valve 18 are turned off to complete the cleaning of the pipe and the spray gun 176.
[0036] Furthermore, it also includes a steam input pipe 103, the end of which is connected to a first steam pipe 101 and a second steam pipe 102 via a tee connector. The first steam pipe 101 is connected to the spray pipe 111, and the second steam pipe 102 is connected to multiple spray guns 176. Steam cleaning serves as an auxiliary cleaning method, and its operating mechanism is the same as that of hot water cleaning. Steam cleaning is only performed on the spray distribution pipe and the high-pressure spray guns 176. During cleaning, high-temperature steam is input through the steam input pipe 103. The steam passes through the first steam pipe 101 or the second steam pipe 102 to clean the spray distribution pipe 111 and the spray guns 176, respectively. Valves are installed on both the first steam pipe 101 and the second steam pipe 102 to control the steam flow and thus change the cleaning target.
[0037] Furthermore, a pressure regulating reflux valve 145 is provided between the reflux pipe 112 and the dispersant storage tank 60. The speed and pressure of the waterproof dispersant refluxing back to the dispersant storage tank 60 are controlled by the opening and closing of the pressure regulating reflux valve 145.
[0038] Furthermore, a return valve 84 for the collection tank 30 is provided between the return pipe 112 and the collection tank 30. The return state of the waterproof dispersant is controlled by the opening and closing state of the collection tank 30 return valve 84, and it is closed during cleaning to prevent hot water from entering.
[0039] The working principle of this utility model is as follows: During the spraying stage, the inlet valve 7, the first feed pump 90, the inlet valve 70, and the isolation valve 71 are opened, while the water inlet valve 8 is closed. The waterproof dispersant passes through the spraying pipe 111 and the spraying diversion pipe 1. The spray gun 176 is opened, and the waterproof dispersant is sprayed from the spray gun 176 to spray the board. The remaining waterproof dispersant returns to the collection storage tank 30 through the return pipe 112. During the spraying process, hot water in the hot water storage tank 5 is pumped into the heating outer tube 200 by the hot water circulation pump 170. The hot water in the heating outer tube 200 exchanges heat with the waterproof dispersant in the spraying pipe 111, the spraying diversion pipe 1, and the return pipe 112, heating and maintaining the temperature of the waterproof dispersant. Finally, the hot water is circulated back to the hot water storage tank 5.
[0040] The cleaning process is divided into three stages:
[0041] During the pipeline cleaning stage, the inlet valve 8 is opened and the agent inlet valve 7 is closed. Hot water is used to clean the pipeline by passing through the spraying pipeline 111, the first feed pump 90, the filter 110, the spraying diversion pipeline 1, the spray gun 176, the return pipeline 112, and various valves and fittings.
[0042] During the separate cleaning stage of spray gun 176, open the hot water inlet valve 8, close the return valve 84 of the collection tank 30 and the spray return valve 18, open the spray gun 176 and the cleaning pump 131, and clean the spray gun 176 separately through the independent cleaning pump 131 to complete the cleaning of the spray gun 176 and the spray diversion pipe 1.
[0043] In the steam cleaning stage, steam cleaning serves as an auxiliary cleaning method. The steam cleaning mechanism is the same as that of hot water cleaning. Steam cleaning is only performed on the spray diversion pipe 1 and the high-pressure spray gun 176. During cleaning, high-temperature steam is introduced through the steam input pipe 103. The steam passes through the first steam pipe 101 or the second steam pipe 102 to clean the spray diversion pipe 1 and the spray gun 176, respectively. Valves are installed on both the first steam pipe 101 and the second steam pipe 102 to control the steam flow and thus change the cleaning target.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
