Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-based adhesive production technology, and in particular to an emulsion dripping device for water-based adhesive production. Background Technology
[0002] Water-based adhesives are environmentally friendly adhesives made by using natural or synthetic polymers as binders and water as a solvent or dispersant, replacing toxic organic solvents that pollute the environment. Existing water-based adhesives are not 100% solvent-free and may contain limited volatile organic compounds as additives in their water-based medium to control viscosity or flowability. Their advantages mainly include being non-toxic, non-polluting, non-flammable, safe to use, and easy to implement clean production processes. The reaction vessel plays a crucial role in the production of water-based adhesives, achieving the mixing, reaction, and polymerization of raw materials through processes such as stirring and heating.
[0003] The control of the emulsion dropping rate directly affects the stability of the polymerization process and ultimately the intrinsic quality of the emulsion product. Therefore, the control of the relative velocity of the emulsion and the dropping procedure are the most important parameters in emulsion polymerization. Since the emulsion is directly dropped into the mixing tank and falls onto the surface of the mixed material, it cannot be directly dropped into the interior of the mixed material for stirring. The dispersion effect is not good enough, which affects the polymerization process of the material and leads to poor product quality. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] To address the issue that direct addition to the mixture is not possible for proper stirring, resulting in insufficient dispersion and thus affecting the polymerization process and leading to poor product quality.
[0006] (2) Technical solution
[0007] The technical solution of this utility model is as follows: an emulsion dripping device for the production of water-based adhesives, comprising a main body, including a mixing tank, a mixing cover, a mounting base, a support frame, a discharge pipe, a feed pipe, a dripping component, a mixing component, and a discharge valve. The mixing tank is located in the middle of the main body, with a mixing cover installed above it and a support frame below it. A mounting base is fixed to the surface of the support frame, and the mixing tank is mounted on the surface of the mounting base. A feed pipe is installed at a through hole on the surface of the mixing cover, and a discharge pipe is installed at a discharge port on the bottom of the mixing tank. A discharge valve is installed at one end of the discharge pipe. A mixing component and a dripping component are installed inside the mixing tank. By starting a suction pump and cooperating with a flow pump, the flow rate of the emulsion is controlled within a suitable range. By setting a fixing ring and a dripping pipe in the mixing tank, and opening the electromagnetic control valve, the emulsion is dripped into the mixture through the connecting pipe for thorough mixing. The emulsion dripping into the material provides good dispersion, accelerates material polymerization, and improves product quality.
[0008] Furthermore, the dripping assembly includes a suction pump, a delivery pipe, a flow pump, a solenoid control valve, a connecting pipe, a fixing ring, and dripping pipes. Two fixing rings are installed inside the mixing tank, and multiple dripping pipes arranged in a circular pattern are mounted on the surface of each fixing ring. The dripping pipes have an inverted J-shaped structure. A connecting pipe is installed inside the fixing rings, and a connecting pipe is installed inside the mixing tank, connecting in series with the multiple dripping pipes on the fixing rings. A suction pump is mounted on the surface of the support frame, and a U-shaped delivery pipe is installed at one end of the suction pump, with one end of the delivery pipe penetrating the mixing tank. The emulsion is connected to one end of a connecting pipe inside the mixing tank. A flow pump is installed on the surface of the conveying pipe, and an electromagnetic control valve is installed on the surface of the conveying pipe on one side of the flow pump. By setting up a dripping component, the flow rate of the emulsion is controlled within a suitable range by starting the suction pump and cooperating with the flow pump. By setting a fixing ring and a dripping pipe in the mixing tank, the electromagnetic control valve is opened to drip the emulsion into the interior of the mixture through the connecting pipe for thorough mixing. The emulsion is dripped into the interior of the material, resulting in good dispersion, accelerating the polymerization of the material, and improving product quality.
[0009] Furthermore, the stirring assembly includes a servo motor, a stirring rod, stirring blades A, a base plate, and a stirring impeller. A base plate is installed on the bottom surface of the stirring tank, and a discharge hole is opened on the surface of the base plate. A servo motor is installed on the surface of the stirring cover, and the output shaft of the servo motor passes through the stirring cover and is connected to one end of the stirring rod located inside the stirring tank. Stirring blades A are installed on the surface of the stirring rod, and a stirring impeller is installed at the end of the stirring rod away from the servo motor. The stirring impeller is in contact with the base plate. To further improve the mixing quality, the stirring assembly is used. During operation, the servo motor is started to drive the stirring blades A on the stirring rod to rotate, which, in conjunction with the stirring impeller, tumbles the mixture at the bottom of the stirring tank. Under the rotation of the stirring blades A, the raw materials are mixed and stirred more thoroughly, improving the efficiency of material reaction and polymerization, and ultimately improving product quality.
[0010] Furthermore, stirring blades B are installed on the surface of the stirring rod, and stirring blades B and stirring blades A are installed alternately on the surface of the stirring rod, resulting in a good stirring and mixing effect.
[0011] Furthermore, both stirring blade A and stirring blade B are arranged in a spiral structure. Stirring blade B is located outside stirring blade A, and stirring blade B and stirring blade A are in opposite stirring directions. By arranging stirring blade A and stirring blade B in a spiral structure, the materials can be stirred alternately, thereby improving mixing efficiency.
[0012] Furthermore, a scraper is installed at one end of each blade on the impeller. The scraper fits snugly against the mixing tank. By installing the scraper on the impeller, the scraper can agitate and mix the material near the bottom inner wall while the impeller is mixing, thereby improving the quality of the emulsion product.
[0013] Furthermore, the scraper is designed with a triangular block structure, which facilitates scraping and turning over the mixture accumulated at the bottom, and makes it easy to stir and turn over the bottom.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the flow rate of the emulsion is controlled within a suitable range by starting the suction pump and cooperating with the flow pump. A fixing ring and a dripping pipe are installed in the mixing tank, and the electromagnetic control valve is opened to drip the emulsion into the mixture through the connecting pipe, ensuring thorough mixing. The emulsion is dripped into the material, resulting in good dispersion, accelerating material polymerization, and improving product quality. To further enhance the mixing quality, a stirring component is added. During use, the servo motor drives the stirring blades A on the stirring rod to rotate, which, together with the stirring impeller, tumbles the mixture at the bottom of the mixing tank. The rotation of the stirring blades A further mixes the raw materials, making the mixing more thorough, improving the efficiency of material reaction and polymerization, and ultimately enhancing product quality.
