Description

Technical Field

[0001] This utility model relates to the field of artificial board processing technology, specifically to a device for mixing and applying waterproofing agents to artificial boards. Background Technology

[0002] Engineered wood products typically use waterproof paraffin wax as a waterproofing agent. For medium- and high-density fiberboard (MDF), molten paraffin wax is injected into a discharge auger and ground together with wood chips using a hot mill to disperse it onto the fiber surface, thus achieving the desired waterproofing. This mixed method provides good paraffin coating, but only a portion of the wax penetrates into the fibers, resulting in waste. For particleboard and oriented strand board (OSB), waterproofing agents are applied after drying. When using molten paraffin wax as a waterproofing agent, the amount used is relatively small, requiring a larger application rate to achieve uniform coverage and the desired waterproofing effect. Using emulsified paraffin wax as a waterproofing agent requires pre-preparation of the emulsion and the use of emulsifiers, stabilizers, and other auxiliary materials, increasing production costs and the presence of hydrophilic substances. Therefore, there is an urgent need for a mixed application device for engineered wood products to address these issues. Utility Model Content

Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] In this embodiment of the utility model, please refer to Figures 1 to 7A device for mixing and applying a waterproofing agent for engineered wood products includes: a resin buffer heating tank 1 and a paraffin melting tank 2. The resin buffer heating tank 1 has two sets for heating the resin. The paraffin melting tank 2 is used to heat the paraffin. The resin buffer heating tank 1 is connected to a dual filter 31 via a pipe 1. The dual filter 31 is connected to a hot fluid mixer 4 via a pipe 2.

The homogenizing filter 5 is used to grind and filter the mixed solution. The homogenizing filter 5 is connected to a high-pressure atomizing spraying mechanism 6 via a pipe 6. The high-pressure atomizing spraying mechanism 6 is used to spray the mixed solution and mix it with the wood raw material.

[0047] The resin buffer heating tank 1 heats the resin, the paraffin melting tank 2 melts the paraffin, and the resin solution and paraffin liquid are filtered through a dual filter and then enter the hot fluid mixer 4 for mixing. The homogenizing filtration mechanism grinds and filters the mixed solution, and the high-pressure atomizing spraying mechanism sprays the mixed solution to mix with the wood raw material.

[0048] In this embodiment, the resin is any one of urea-formaldehyde resin, phenolic resin, melamine resin, vinyl acetate resin, ethyl acetate-ethylene copolymer emulsion, and modified starch resin.

[0049] In this embodiment, both pipe 2 and pipe 4 are equipped with gear metering pumps and flow meters.

[0050] As one embodiment of this utility model, please refer to Figures 1 to 3 The resin buffer heating tank 1 includes: a tank body 11, a drain port 10 at the bottom of the tank body 11, a liquid outlet pipe 19 on one side of the bottom of the tank body 11, the liquid outlet pipe 19 being connected to a dual filter 31 via a pipe, a stirring assembly inside the tank body 11 for stirring the resin, the tank body 11 being connected to a feeding assembly, a heating assembly inside the tank body 11 for heating the resin, and a thermometer insertion tube 113 at the bottom of one side of the tank body 11.

[0051] The stirring assembly includes:

[0052] Drive component 12 is connected to tank body 11;

[0053] The drive rod 13 is connected to the output end of the drive component 12. The drive rod 13 is located inside the tank body 11 and is rotatably connected to it.

[0054] The oblique blade propeller 14 is connected to the drive rod 13;

[0055] The propeller 15 is connected to the bottom end of the drive rod 13;

[0056] The feeding assembly includes:

[0057] The feed pipe section 16 penetrates the top of the tank body 11 and is connected thereto;

[0058] The material distribution ring 17 is connected to the bottom end of the feed pipe section 16, and the material distribution ring 17 is circular.

[0059] The pressure stabilizing hole 18 is opened at the top of the feed pipe section 16 and is located inside the tank body 11;

[0060] The material distribution hole 110 is provided on the material distribution tube ring 17. The material distribution hole 110 is provided in several groups and is arranged in a circumferential manner with equal spacing.

[0061] The heating component includes:

[0062] A straight section heating coil 111 is connected to the side wall of the tank 11 and is located in the lower middle part of the tank 11. The straight section heating coil 111 is inclined and coiled along the inner wall of the tank 11. The top end of the straight section heating coil 111 penetrates the top of the tank 11, and the bottom end of the straight section heating coil 111 penetrates the bottom of the tank 11.

[0063] The bottom heating coil 112 is located at the bottom of the tank 11 and is coiled in a serpentine shape. The top end of the bottom heating coil 112 penetrates the top of the tank 11, and the bottom end of the bottom heating coil 112 penetrates the bottom of the tank 11.

[0064] Resin enters the distribution ring 17 from the feed pipe section 16 and flows out through the distribution hole 110, allowing the resin to disperse rapidly. The pressure stabilizing hole 18 keeps the pressure inside the feed assembly consistent with the pressure inside the tank, preventing the liquid weight inside the feed assembly below the liquid level from suddenly falling when the liquid level drops, as this could cause a liquid shock wave to impact the weighing sensor in the buffer tank and cause measurement distortion. The straight section heating coil 111 increases the heating area of ​​the tank 11, rapidly heating the resin. 1. During use, the resin is constantly immersed in the resin to prevent the residual resin liquid adhering to the straight section heating coil 111 from being heated, dried, solidified, and clumped. The bottom heating coil 112 heats and keeps the cold resin solution warm. The driving component 12 drives the driving rod 13 to rotate, and the driving rod 13 drives the inclined blade propeller 14 and the propeller 15 to rotate, pushing the cold resin solution that has just entered the tank 1 to the lower heating component for rapid heating. After reaching the bottom of the tank, it flows back up to the upper part, mixing with the original hot resin solution and increasing the heating rate.

[0065] In this embodiment, the oblique blade 14 has two mixing flow patterns: axial and circumferential, which mix the two resin solutions at different temperatures more thoroughly and press them downward.

[0066] In this embodiment, the tank 11 is equipped with a buffer tank weighing sensor to measure the resin.

[0067] As one embodiment of this utility model, please refer to Figure 1 and Figure 4 The thermal fluid mixer 4 includes:

[0068] The resin main pipe 41 is connected to the dual filter 31 via pipe 2;

[0069] The paraffin liquid injection tube 42 has one end connected to the double filter 32 via the pipe 4, and the other end is inserted obliquely into the resin main tube 41 and connected to it.

[0070] An insulating jacket 43 is fitted over the resin main tube 41 and the paraffin liquid injection tube 42. The insulating jacket 43 has an inlet at the bottom and an outlet at the top.

[0071] The heated resin enters the resin main tube 41, and the paraffin solution enters the resin main tube 41 through the paraffin liquid injection tube 42. The paraffin solution impacts the resin and disturbs the fluid at the junction, so that the two can mix in a short time to achieve mass and heat transfer. Steam or heat transfer oil is introduced into the insulation jacket 43 for heating and insulation to maintain the temperature of the mixed raw materials.

[0072] In this example, both the resin main pipe 41 and the paraffin liquid injection pipe 42 are equipped with return pipes at their front ends. When the production line malfunctions and requires a short-term shutdown, the unmixed resin and paraffin liquid are respectively transported back to the resin buffer heating tank 1 and the paraffin melting tank 2.

[0073] As one embodiment of this utility model, please refer to Figure 1 and Figure 5 The homogenizing filtration mechanism 5 includes:

[0074] The grinding mill 51 has its input end connected to the inside of the resin main pipe 41 via pipe five, and is used to grind the mixed solution.

[0075] The self-cleaning filter 52 has an input end connected to the output end of the grinder 51. The self-cleaning filter 52 is provided with an impurity output end and a liquid output end. The impurity output end is connected to the input end of the grinder 51 through a circulation pipe.

[0076] Flow meter 53 is installed on the circulation pipeline.

[0077] The resin and paraffin mixture enters the grinder 51. After the grinder 51 grinds and refines the raw material, the refined liquid raw material enters the self-cleaning filter 52 under the system pressure. The liquid flows out through the filter screen, and mechanical impurities are blocked on the outside of the filter screen. When the accumulated amount of impurities makes the filter pressure greater than the outlet pressure, the bottom automatic drain valve opens, the impurities are discharged and returned to the grinder 51 for re-grinding, ensuring that the high-pressure nozzle 64 is not blocked. The flow meter 53 is used to measure the flow rate of the liquid raw material returned to the grinder 51 for re-grinding.

[0078] In this embodiment, a pressure transmitter is also provided on the circulation pipeline for measuring the pipeline pressure.

[0079] In this embodiment, the homogenizing filter mechanism 5 can be connected to compressed air and hot water for cleaning. When the production line malfunctions and requires a short-term shutdown, the mixed resin and paraffin liquid are blown into the high-pressure atomizing spraying mechanism 6 with compressed air to prevent continuous heating, curing, or charring.

[0080] As one embodiment of this utility model, please refer to Figure 1 , Figure 6 and Figure 7 The high-pressure atomizing spraying mechanism 6 includes:

[0081] The input end of the high-pressure gear pump 61 is connected to the liquid output end of the self-cleaning filter 52 via pipe six.

[0082] The input end of the adhesive dispenser 62 is connected to the output end of the high-pressure gear pump 61;

[0083] The high-pressure nozzle 64 is connected to the output end of the adhesive dispenser 62 via a pipe 7;

[0084] Flow switch 63 is installed on pipe seven;

[0085] The cylinder lubrication pump 65 is connected to the high-pressure nozzle 64;

[0086] The high-pressure nozzle 64 includes: a nozzle body 641, the nozzle body 641 having a spray hole at its bottom, a glue inlet 643 and a compressed air inlet 644 on the nozzle body 641, the glue inlet 643 being connected to a glue distributor 62 via a pipe 7, and a striker 642 being slidably disposed inside the nozzle body 641, the bottom of the striker 642 abutting against the spray hole.

[0087] The high-pressure gear pump 61 draws away the filtered mixed solution, and the glue distributor 62 distributes the mixed solution. The mixed solution enters the nozzle body 641 through the glue inlet 643. Compressed air enters the nozzle body 641 through the compressed air inlet 644, lifting the impact pin 642 so that the mixed solution can be sprayed out from the spray hole. The lifting height of the impact pin 642 can be controlled by controlling the pressure of the compressed air, thereby controlling the spray flow rate of the mixed solution.

[0088] The working principle of this utility model is as follows: Resin enters the distribution pipe ring 17 from the feed pipe section 16 and flows out through the distribution hole 110, allowing the resin to disperse rapidly. The straight section heating coil 111 and the bottom heating coil 112 heat and keep the resin solution warm. The driving component 12 drives the driving rod 13 to rotate, and the driving rod 13 drives the inclined blade paddle 14 and the propeller paddle 15 to rotate, pushing the cold resin solution that has just entered the tank 1 downwards to be rapidly heated. After reaching the bottom of the tank, it flows back upwards, mixing with the original hot resin solution and increasing the heating rate. The paraffin melting tank 2 melts the paraffin. The resin solution is filtered through the double filter 31, and the paraffin solution is filtered through the double filter 32. The resin enters the resin main pipe 41, and the paraffin solution enters the resin main pipe 41 through the paraffin liquid injection pipe 42. The solution impacts the resin and agitates the fluid at the confluence, allowing the two to mix in a short time. The resin and paraffin mixture enters the grinder 51, where it grinds and refines the raw material. The refined liquid material then enters the self-cleaning filter 52 under system pressure. The liquid flows out through the filter screen, where mechanical impurities are blocked on the outside. The high-pressure gear pump 61 removes the filtered mixture, and the adhesive distributor 62 distributes the mixture. The mixture enters the nozzle body 641 through the adhesive inlet 643, and compressed air enters the nozzle body 641 through the compressed air inlet 644, lifting the impact pin 642 so that the mixture can be sprayed out of the spray hole. The lifting height of the impact pin 642 can be controlled by controlling the pressure of the compressed air, thereby controlling the flow rate of the mixture.
