Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a reaction vessel for preparing room temperature curing silicone resin coatings that prevents dead angles. Background Technology

[0002] Room temperature curing silicone resin coatings are commonly prepared using anchor-type reactors. An anchor-type agitator is installed at the lower end of the stirring shaft in the reactor, and its rotation achieves mixing of the raw materials. A traditional anchor-type agitator can be found in [reference needed]. Figure 2 As shown.

[0003] To avoid collision between the anchor-type agitator and the vessel body, a dead corner will be formed below the anchor-type agitator. This will cause the raw materials below the anchor-type agitator to easily adhere to the bottom of the vessel body, making it difficult to mix them thoroughly and thus affecting the quality of the product.

[0004] Therefore, how to overcome the above-mentioned defects has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses a room-temperature curing silicone resin coating preparation reactor that prevents dead angles.

[0006] This utility model provides a room temperature curing silicone resin coating preparation reactor with no dead angle, including a reactor body, a motor-driven stirring shaft is provided in the reactor body, an anchor-type stirring paddle is provided at the lower end of the stirring shaft, the anchor-type stirring paddle includes a paddle bottom, the two ends of the paddle bottom are provided with upwardly extending paddle sides, and the middle position of the paddle bottom is arched upward to form a U-shape with the opening facing downward, so that the paddle bottom and the bottom of the reactor body form a placement cavity.

[0007] The lower end of the stirring shaft passes through the bottom of the impeller and extends into the placement chamber;

[0008] The lower end of the stirring shaft is connected to a scraper located inside the placement chamber;

[0009] The lower end of the scraper rests against the inner wall of the vessel.

[0010] The beneficial effects of the above settings are: 1. When the stirring shaft rotates, the scraper rotates along with it, scraping off the raw materials adhering to the bottom of the vessel. These scraped raw materials are mixed with other raw materials as the anchor-type stirring paddle rotates, thereby eliminating dead corners and improving mixing efficiency; 2. The bottom opening of the paddle faces downward, so that when the paddle bottom rotates, the liquid below the paddle bottom flows downward in a directional direction, impacting the bottom of the vessel, which further improves the mixing efficiency of the liquid at the bottom of the vessel.

[0011] Traditional anchor-type agitator blades are integrally molded with the agitator shaft, making disassembly and assembly difficult. Furthermore, when the anchor-type agitator blade wears out, the entire blade needs to be replaced, resulting in high costs. Therefore, a further improvement involves incorporating sleeves on both the anchor-type agitator blade and the scraper to connect to the agitator shaft. Bolts pass through these sleeves and are threaded onto the agitator shaft. This allows for a detachable connection of the anchor-type agitator blade, facilitating shaft assembly and disassembly. Moreover, when the anchor-type agitator blade wears out, only the anchor-type agitator blade needs to be replaced, thus reducing costs.

[0012] The lower end of the paddle side is fixedly connected to the paddle bottom, while the upper end is suspended, making it easy for the upper end of the paddle side to bend inward under force when the anchor-type agitator is stirring. Based on this, a further improvement is made: the paddle sides are connected by a horizontally arranged connecting rod; the sleeve is set in the middle of the connecting rod.

[0013] To further improve the connection strength of the anchor-type mixing paddle, a sleeve is also provided at the center of the paddle bottom.

[0014] Since the scraper comes into contact with the vessel body, its wear rate is faster. To facilitate the disassembly and assembly of the scraper, a further design is made: a sleeve is also connected to the upper end of the scraper.

[0015] The shape of the blade base directly affects the installation space and operation difficulty of the scraper. Based on this, a further improvement is made: the middle part of the blade base is flared.

[0016] The traditional method has a large gap between the upper end of the paddle and the liquid surface inside the vessel, resulting in low mixing efficiency. Based on this, a further improvement is to extend the paddle upward to the liquid surface.

[0017] To further improve the mixing efficiency within the vessel, a spiral blade is connected between the sides of the impeller. The spiral direction of the blade is configured such that when the stirring shaft rotates, the vortex formed by the blade causes the liquid at the bottom of the vessel to flow upwards. This blade configuration not only increases the flow velocity of the liquid within the vessel, but also causes the vortex formed by the blade to rapidly move the liquid below the impeller away from the bottom of the vessel.

[0018] The beneficial effects of this utility model are: 1. When the stirring shaft rotates, the scraper rotates along with it, scraping off the raw materials adhering to the bottom of the vessel. These scraped raw materials are mixed with other raw materials as the anchor-type stirring paddle rotates, thereby eliminating dead corners and improving mixing efficiency; 2. The bottom opening of the paddle faces downward, so that when the paddle bottom rotates, the liquid below the paddle bottom flows downward in a directional direction, impacting the bottom of the vessel, thereby further improving the mixing efficiency of the liquid at the bottom of the vessel.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figure 1 As shown, this utility model discloses a room temperature curing silicone resin coating preparation reactor with anti-dead angle, including a vertical reactor body 1. A stirring shaft 3 driven by a motor 2 and arranged vertically is provided inside the reactor body 1. An anchor-type stirring paddle 4 is provided at the lower end of the stirring shaft 3. The anchor-type stirring paddle 4 includes a paddle bottom 41 and upwardly extending paddle sides 42 at both ends of the paddle bottom 41.

[0025] The middle part of the impeller bottom 41 arches upward, forming a U-shape with the opening facing downward, thus creating a placement cavity 5 between the impeller bottom 41 and the bottom of the vessel body 1. The lower end of the stirring shaft 3 passes through the impeller bottom 41 and extends into the placement cavity 5. The lower end of the stirring shaft 3 is connected to a scraper 6 located in the placement cavity 5. The lower end of the scraper 6 abuts against the inner wall of the vessel body 1. The middle part of the impeller bottom 41 is flared, thereby expanding the space of the placement cavity 5 and facilitating the installation and removal of the scraper 6.

[0026] The blade sides 42 are connected by horizontally arranged connecting rods 8 to improve the structural stability of the blade sides 42 and prevent the top of the blade sides 42 from bending inward.

[0027] A sleeve 7 is connected to the middle of the connecting rod 8, the middle of the impeller base 41, and the upper end of the scraper 6. The sleeve 7 is fitted onto the stirring shaft 3, and bolts pass through the sleeve 7 and are threadedly connected to the stirring shaft 3. This achieves a detachable connection between the anchor-type stirring impeller 4 and the scraper 6, which not only facilitates the disassembly and assembly of the stirring shaft 3, but also reduces costs by requiring only the replacement of the anchor-type stirring impeller 4 or the scraper 6 when they wear out.

[0028] The paddle side 42 extends upward to the liquid surface, which can increase the driving force of the liquid in the vessel 1, thereby improving the mixing efficiency.

[0029] A spiral blade 9 is also connected between the sides 42 of the impeller. The spiral direction of the blade 9 is configured such that when the stirring shaft 3 rotates, the vortex formed by the blade 9 causes the liquid at the bottom of the vessel 1 to flow upward. The blade 9 not only increases the flow rate of the liquid in the vessel 1, but also the vortex formed by the blade 9 causes the liquid below the impeller bottom 41 to move away from the bottom of the vessel 1 quickly.

[0030] Compared with the prior art, the beneficial effects of this embodiment are: 1. When the stirring shaft 3 rotates, the scraper 6 rotates accordingly, scraping off the raw materials adhering to the bottom of the vessel body 1. These scraped raw materials are mixed with other raw materials as the anchor-type stirring paddle 4 rotates, thereby eliminating dead corners and improving mixing efficiency; 2. The bottom of the paddle 41 opens downwards, so that when the bottom of the paddle 41 rotates, the liquid below the bottom of the paddle 41 flows downwards in a directional direction, impacting the bottom of the vessel body 1, thereby further improving the mixing efficiency of the liquid at the bottom of the vessel body 1.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
