Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel feeding technology, specifically a feeding device for the production of water-based damping adhesive. Background Technology
[0002] Water-based damping adhesive is an environmentally friendly adhesive that uses water as a solvent. It has excellent shock absorption, sound insulation, and vibration damping properties. After curing, this type of damping adhesive can effectively absorb and dissipate mechanical energy, thereby reducing structural vibration and noise. Compared with traditional oil-based damping adhesives, water-based damping adhesives have a lower content of volatile organic compounds (VOCs), making them more environmentally friendly and having less impact on human health.
[0003] In the production of water-based damping adhesive, the various raw materials must first be added to the reactor sequentially according to production specifications. Next, the raw materials are thoroughly mixed using the stirring device within the reactor. During the mixing process, necessary auxiliary materials such as plasticizers, stabilizers, crosslinking agents, and fillers are added as needed, according to production requirements.
[0004] To ensure the effective addition of excipients during the production of water-based damping adhesives, two independent dosing lines are typically used to add the excipients to the reactor separately for solid and liquid components. This is done to prevent the liquid and solid excipients from sticking together before entering the reactor, thereby ensuring uniformity in the subsequent mixing process.
[0005] In the production process of water-based damping adhesives, several problems arise when solid and liquid additives are added to the reactor containing the raw materials being stirred. Specifically, solid additives may form clumps upon contact with the stirring raw materials. These clumps are only agitated within a small area, reducing the uniformity of the mixture. Simultaneously, the addition of liquid additives may encapsulate a large amount of solid additives, forming clumps that are difficult to disperse quickly and evenly into the other raw materials within the reactor. Therefore, to achieve the desired mixing effect, the stirring time needs to be extended, which to some extent reduces the production efficiency of water-based damping adhesives. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a feeding device for the production of water-based damping adhesive, thereby improving the production efficiency of water-based damping adhesive.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for the production of water-based damping adhesive, comprising a reactor, a raw material feeding port penetrating through the middle of the top of the reactor, and auxiliary material feeding ports penetrating through the top of the reactor on both sides of the raw material feeding port. A feeding pipe is fixedly connected to each of the two auxiliary material feeding ports, and a dispersion pipe is fixedly connected and connected to the end of the feeding pipe near the inside of the reactor. Several material discharge ports are penetrating through the side of the two dispersion pipes near the bottom of the reactor.
[0008] Furthermore, a feeding hopper is fixedly connected to the inner wall of the raw material feeding port.
[0009] Furthermore, the ends of both dispersion tubes furthest from the feed inlet are inclined downwards.
[0010] Furthermore, the two dispersion tubes extend downwards along both sides of the inner wall of the reactor.
[0011] Furthermore, a vibrator is fixedly connected to the outer wall of the dispersion tube on the side away from several material discharge ports.
[0012] Furthermore, the outer wall of the dispersion tube is connected with several clamps, all of which are sleeved on the outer wall of the dispersion tube and fixedly connected to the inner wall of the reactor.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This feeding device for the production of water-based damping adhesive uses two feeding pipes to separately add powdered and liquid additives into the reactor, preventing the additives from coming into contact with each other and clumping. At the same time, a dispersion pipe of the same specification disperses the additives into the reactor through multiple discharge ports at the bottom, so that the added additives can be added more evenly and participate in the mixing and processing of water-based damping adhesive raw materials, thereby improving the production efficiency of water-based damping adhesive.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1 to 3 A feeding device for the production of water-based damping adhesive includes a reactor 1. A raw material feeding port 101 is provided through the middle of the top of the reactor 1. Auxiliary material feeding ports 102 are provided through the top of the reactor 1 on both sides of the raw material feeding port 101. A feeding pipe 2 is fixedly connected to each of the two auxiliary material feeding ports 102. A dispersion pipe 3 is fixedly connected and communicated to the end of the feeding pipe 2 near the inside of the reactor 1. Several discharge ports 301 are provided through the side of the two dispersion pipes 3 near the bottom of the reactor 1.
[0021] like Figures 1 to 3 As shown, the feeding device for producing water-based damping adhesive in this invention is structurally similar to existing feeding devices for producing water-based damping adhesive. The main improvement of this invention is that it enables the added auxiliary materials to be more evenly dispersed within the reaction vessel 1, such as... Figures 1 to 3 As shown, in use, the feeding device for producing water-based damping adhesive of this utility model adds powdered and liquid auxiliary materials into the reactor 1 through two feeding pipes 2. When the auxiliary materials fall from the feeding pipes 2 into the dispersion pipes 3 inside the reactor 1, they are dispersed and fall downwards through multiple discharge ports 301, so that the auxiliary materials can fall into the reactor 1 more evenly. This makes the initial mixing of the auxiliary materials and the water-based damping adhesive raw materials in the reactor 1 more uniform, avoids the auxiliary materials from accumulating in one place and causing agglomeration, and improves the production efficiency of water-based damping adhesive.
[0022] like Figure 1 and Figure 2 As shown, a feeding hopper 4 is fixedly connected to the inner wall of the raw material feeding port 101. The feeding hopper 4 is fixedly installed inside the raw material feeding port 101. When adding water-based damping adhesive raw materials, the raw materials can fall from the middle position of the top of the reactor 1 through the feeding hopper 4, avoiding the raw materials falling onto the dispersion tube 3.
[0023] like Figure 2 and Figure 3 As shown, the ends of both dispersion tubes 3 furthest from the feeding pipe 2 are inclined downwards. By inclining the dispersion tubes 3 downwards, the auxiliary material, after entering the dispersion tubes 3, can fall from the upper discharge port 301 under the action of gravity, gradually falling towards the lower discharge port 301 and dispersing to the lower part of the dispersion tubes 3, thus improving the effect of dispersing and falling of the auxiliary material.
[0024] like Figure 2 and Figure 3As shown, two dispersion tubes 3 extend downwards along both sides of the inner wall of the reactor 1. By extending the two dispersion tubes 3 downwards along both sides of the inner wall of the reactor 1, the liquid excipients and powder excipients will not come into contact when falling, thus improving the mixing effect of the excipients and the raw materials inside the reactor 1.
[0025] like Figure 2 As shown, a vibrator 5 is fixedly connected to the outer wall of the dispersion tube 3 on the side away from the several discharge ports 301. The vibrator 5 can create a vibration effect on the dispersion tube 3, thereby gradually vibrating off the auxiliary material attached to the inner wall of the dispersion tube 3, reducing the possibility of blockage inside the dispersion tube 3. The vibrator 5 can be an electromagnetic vibrator, which can be directly installed on the dispersion tube 3. When it generates vibration, it synchronously drives the dispersion tube 3 to form a small amplitude vibration, so that the auxiliary material inside the dispersion tube 3 falls slowly under the action of vibration and falls from the multiple discharge ports 301.
[0026] like Figure 2 and Figure 3 As shown, several clamps 6 are connected to the outer wall of the dispersion tube 3. These clamps 6 are all fitted onto the outer wall of the dispersion tube 3 and are fixedly connected to the inner wall of the reactor 1. The clamps 6 securely install the dispersion tube 3 inside the reactor 1, facilitating both fixation and easy disassembly, cleaning, or replacement of the dispersion tube 3 in case of malfunction. The clamps 6 are detachably connected to the inner wall of the reactor 1, such as by bolts.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
