Description

Technical Field

[0001] This utility model relates to a coating production equipment, and more specifically, to a reaction vessel for coating production. Background Technology

[0002] A reaction vessel for paint production is a chemical equipment specifically designed for manufacturing paint products. It is primarily used for mixing, dispersing, dissolving, and carrying out chemical reactions to transform various raw materials (such as resins, pigments, solvents, and other additives) into the final paint product.

[0003] In the coating production process, especially when the formula contains solid particles (such as pigments, fillers, etc.), these particles will cause friction and impact on the inner wall of the reactor under the action of the agitator. Over time, this will cause the inner wall material to wear down gradually, and coating residues will remain on the inner wall of the reactor, which is inconvenient to clean, making cleaning difficult and reducing work efficiency.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reaction vessel for paint production, which aims to solve the technical problem of inconvenient cleaning of residues.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a reaction vessel for coating production, comprising a vessel body, a cover plate movably placed on the top of the vessel body, a feed pipe fixedly installed on the top of the cover plate, a discharge pipe fixedly installed on the bottom of the vessel body, a motor fixedly installed on the top of the cover plate, a stirring shaft fixedly installed at the output end of the motor, a titanium alloy annular baffle movably arranged inside the vessel body, the outer wall of the titanium alloy annular baffle contacting the inner wall of the vessel body, a limiting bolt movably inserted and connected on both the left and right sides of the upper end of the cover plate, the titanium alloy annular baffle being detachably and movably connected to the bottom of the cover plate by two limiting bolts, a movable plate fixedly installed on both the left and right sides of the outer surface of the cover plate, an electric cylinder fixedly installed on both the left and right sides of the vessel body, the input end of the electric cylinder being electrically connected to an external power supply through an external control switch group, and the output end of the electric cylinder being fixedly connected to the movable plate.

[0007] The present invention is further configured such that the length of the titanium alloy annular baffle is the same as the length of the vessel body.

[0008] The present invention is further configured such that the stirring shaft is located inside the titanium alloy annular baffle.

[0009] In summary, this utility model has the following beneficial effects:

[0010] The titanium alloy annular baffle positioned between the stirring shaft and the vessel effectively blocks direct friction and impact from solid particles onto the inner wall of the vessel, significantly reducing wear. This not only extends the equipment's service life, but also, due to the presence of the titanium alloy annular baffle, paint residue primarily adheres to its surface rather than the inner wall of the vessel. Therefore, after each production run, only the titanium alloy annular baffle needs to be disassembled and cleaned, eliminating the need to clean the entire inner wall of the vessel, greatly simplifying the cleaning process and improving work efficiency.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A reaction vessel for paint production, such as Figures 1 to 4 As shown, the vessel includes a vessel body 1, a cover plate 2 movably placed on the top of the vessel body 1, a feed pipe 3 fixedly installed on the top of the cover plate 2, a discharge pipe 4 fixedly installed on the bottom of the vessel body 1, a motor 5 fixedly installed on the top of the cover plate 2, a stirring shaft 6 fixedly installed at the output end of the motor 5, a titanium alloy annular baffle 7 movably arranged inside the vessel body 1, the outer wall of the titanium alloy annular baffle 7 contacting the inner wall of the vessel body 1, a limiting bolt 8 movably inserted on both the left and right sides of the upper end of the cover plate 2, the titanium alloy annular baffle 7 being detachably and movably connected to the bottom of the cover plate 2 by two limiting bolts 8, a movable plate 9 fixedly installed on both the left and right sides of the outer surface of the cover plate 2, and an electric cylinder 10 fixedly installed on both the left and right sides of the vessel body 1, the input end of the electric cylinder 10 being electrically connected to an external power supply through an external control switch group, and the output end of the electric cylinder 10 being fixedly connected to the movable plate 9.

[0021] like Figure 3 As shown, the length of the titanium alloy annular baffle 7 is the same as the length of the vessel body 1. Since the length of the titanium alloy annular baffle 7 is the same as the length of the vessel body 1, it means that it can cover the entire height of the inner wall of the vessel body 1. This design ensures that the inner wall of the vessel body 1, whether in the upper, middle or lower part, can be effectively protected during the stirring process, preventing solid particles from rubbing and impacting the inner wall of the vessel body 1, thereby reducing the wear of the inner wall.

[0022] like Figure 4 As shown, the stirring shaft 6 is located inside the titanium alloy annular baffle 7. By placing the stirring shaft 6 inside the titanium alloy annular baffle 7, the stirring shaft 6 and the stirring paddle on it can be prevented from directly impacting or rubbing against the baffle, thereby reducing the risk of baffle damage due to long-term use and extending the service life of the baffle.

[0023] Working Principle: In the coating production process, various raw materials are first added to the reactor body 1 through the feed pipe 3. The motor 5 is started, driving the stirring shaft 6 to rotate, thoroughly mixing and dispersing the materials. To reduce direct friction and impact of solid particles on the inner wall of the reactor, a titanium alloy annular baffle 7 is installed between the stirring shaft 6 and the reactor body 1. The titanium alloy annular baffle 7 is tightly attached to the inner wall of the reactor body 1, and the stirring shaft 6 is located inside the baffle. During stirring, solid particles (such as pigments and fillers) circulate within the baffle cavity, preventing direct contact with the inner wall of the reactor. Titanium alloy has high hardness (HRC≥30), low coefficient of friction (0.1-0.2), and corrosion resistance. The baffle surface is smooth, producing only minor scratches when particles impact, significantly reducing reactor wear and effectively preventing direct contact between solid particles and the inner wall of the reactor, thus reducing wear on the inner wall.

[0024] After processing, the finished product is discharged through the discharge pipe 4 at the bottom. When it is necessary to clean or replace the titanium alloy annular baffle 7, the operator starts the two electric cylinders 10. The two electric cylinders 10 are synchronously controlled by the PLC controller. The PLC controller sets the stroke parameters of the electric cylinders 10 through programming (such as speed 50mm / s, displacement 300mm) and sends synchronous pulse signals to the drivers of the two electric cylinders 10 to ensure the consistency of the action. The electric cylinders 10 are electrically connected to the external power supply through an external control switch group, so that the electric cylinders 10 can accurately execute the instructions.

[0025] Start the two electric cylinders 10, which synchronously drive the movable plate 9 to move upward, thereby pushing the cover plate 2 to move upward until the titanium alloy annular baffle 7 is separated from the stirring shaft 6 from the vessel body 1. At this time, the operator can use a tool to turn the two limit bolts 8 to remove the titanium alloy annular baffle 7 from the cover plate 2 for easy cleaning or replacement. The coating is left to adhere only to the inner surface of the titanium alloy annular baffle 7, with no residue on the inner wall of the vessel body 1. The titanium alloy annular baffle 7 can be soaked in cleaning agent or directly rinsed with a high-pressure water gun, and the cleaning can be completed within 10 minutes.

[0026] The titanium alloy annular baffle 7, located between the stirring shaft 6 and the vessel body 1, effectively blocks direct friction and impact of solid particles on the inner wall of the vessel body 1, significantly reducing wear on the inner wall. This not only extends the service life of the equipment, but also, due to the presence of the titanium alloy annular baffle 7, paint residue mainly adheres to its surface rather than the inner wall of the vessel body 1. Therefore, after each production run, only the titanium alloy annular baffle 7 needs to be disassembled and cleaned, eliminating the need to clean the entire inner wall of the vessel body 1, greatly simplifying the cleaning process and improving work efficiency.

[0027] It is worth noting that the motor 5 disclosed in the above embodiments is specifically a Panasonic MI NAS A6 series, the electric cylinder 10 is specifically a Festo EGC series, the PLC controller is a Siemens S7-1200 series, the power supply module is a Mean Well NES-350-24, and the external control switch group and external power supply control the operation of the motor 5 and the electric cylinder 10 adopt the methods commonly used in the prior art.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
