Description

Technical Field

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

[0002] The coating has a certain viscosity. When the coating is discharged from the reactor, some coating will adhere to the discharge port. Since the discharge port diameter is relatively small, the coating adhering to the discharge port can easily cause blockage and waste. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reaction vessel that can prevent the discharge port from clogging.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a reaction vessel, including a tank body, a discharge port provided at the bottom of the tank body, a discharge valve provided at the bottom of the discharge port, the discharge port including a first section communicating with the tank body and a second section on which the discharge valve is installed, the diameter of the second section being larger than the diameter of the first section, a support rod capable of moving and rotating in a vertical direction being provided in the second section, and a scraper being provided near the side wall of the first section for the portion of the support rod extending to and penetrating the first section.

[0005] Furthermore, the sidewall of the second section is provided with an arc-shaped guide groove extending in the vertical direction, and the support rod is provided with a guide rod embedded in the arc-shaped guide groove. When the support rod moves in the vertical direction, the guide rod moves along the arc-shaped guide groove to make the support rod rotate.

[0006] Furthermore, a support block is rotatably connected to the bottom of the support rod, and a drive rod capable of abutting against the support block is provided in the second section. The drive rod pushes the support block to move vertically and drives the support rod to move vertically.

[0007] Furthermore, the bottom of the support block is provided with a positioning groove, and the drive rod includes a first rod body and a second rod body, the first rod body and the second rod body are perpendicular to each other, and a positioning block is provided at the top of the first rod body. The positioning block is embedded in the positioning groove so that the support block abuts against the drive rod.

[0008] Furthermore, the diameter of the positioning groove is larger than the diameter of the positioning block, and the diameter of the positioning groove gradually decreases from bottom to top so that the sidewall of the positioning groove forms a guide slope.

[0009] Furthermore, the end of the guide rod is provided with a guide protrusion, which is embedded in the arc-shaped guide groove.

[0010] In summary, this utility model has the following beneficial effects:

[0011] The up-and-down movement and rotation of the support rod can scrape off the paint adhering to the side wall of the first section. At the same time, the vibration generated by the movement can shake off the paint adhering to the support rod and the scraper itself, thus clearing the first section while reducing paint waste.

Detailed Implementation

[0018] 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.

[0019] See Figures 1 to 5 This embodiment discloses a reaction vessel, including a tank body 100, with a discharge port 200 at the bottom. A discharge valve 400 is located at the bottom of the discharge port 200. The discharge valve 400 includes a rotatable door plate. Normally, the door plate is locked and can seal the bottom of the discharge port 200 to prevent paint leakage. When discharging, the door plate is unlocked and can rotate, opening the bottom of the discharge port 200, allowing paint to flow out from the bottom of the discharge port 200.

[0020] The inlet includes a first section 210 connected to the tank 100 and a second section 220 equipped with a discharge valve 400. The diameter of the second section 220 is larger than that of the first section 210. A support rod 300 capable of moving and rotating vertically is installed inside the second section 220. The portion of the support rod 300 extending into the first section 210 is equipped with a scraper 310 near the side wall of the first section 210. The up-and-down movement and rotation of the support rod 300 can scrape off the paint adhering to the side wall of the first section 210. At the same time, the vibration generated by the movement can shake off the paint adhering to the support rod and the scraper 310 themselves, thus clearing the first section 210 and reducing paint waste.

[0021] Specifically, an arc-shaped guide groove 221 extending vertically is provided on the side wall of the second section 220. A guide rod 320 extending horizontally is fixed to the support rod 300. A guide protrusion 321 is provided at the end of the guide rod 320. The guide protrusion 321 is embedded in the arc-shaped guide groove 221, so that the guide rod 320 can move along the arc-shaped guide groove 221. At the same time, a drive rod 500 is provided. After the discharge port 200 valve is opened, the drive rod 500 can be inserted into the second section 220, so that the drive rod 500 abuts against the support rod 300 and pushes the support rod 300 to move upward. At the same time, when the guide rod 320 moves along the arc-shaped guide groove 221, the support rod 300 also rotates while moving upward, thereby driving the scraper 310 to move upward and rotate. Then, under the action of gravity, the support rod 300 moves downward. With the cooperation of the guide rod 320 and the guide groove, the support rod 300 rotates in the opposite direction, thereby driving the scraper 310 to move downward and rotate in the opposite direction. Repeating this process will clean the coating inside the first section 210, thus preventing the outlet 200 from becoming clogged.

[0022] To reduce the impact of friction generated when the drive rod 500 abuts against the support rod 300 on the rotation of the support rod 300, a support block 330 is rotatably connected to the bottom of the support rod 300 via a bearing 301. A positioning groove 340 is provided at the bottom of the support block 330. The drive rod 500 includes a first rod body 510 and a second rod body 520, which are perpendicular to each other. A positioning block 511 is provided at the top of the first rod body 510. In use, the first rod body 510 faces vertically, and the second rod body 520 faces horizontally. When positioned and embedded in the positioning groove 340, the first rod body 510 abuts against the support block 330, pushing the support block 330 to move while simultaneously pushing the support rod 300 to move. At the same time, the support rod 300 can rotate relative to the support block 330. When the door panel is locked, the support block 330 abuts against the door panel, thereby placing the entire support rod 300 on the door panel. When the door panel is opened, the support rod 300 moves in the direction of gravity, and at the same time, the guide rod 320 moves downward through the arc-shaped guide groove 221 until it slides to the bottom of the arc-shaped guide groove 221 and locks into the arc-shaped guide groove 221, thereby setting the support rod 300 in the second section 220.

[0023] To facilitate alignment of the drive rod 500 with the support block 330 during use, the diameter of the positioning groove 340 is larger than the diameter of the positioning block 511. The diameter of the positioning groove 340 gradually decreases from bottom to top so that the side wall of the positioning groove 340 forms an inclined surface. When the positioning groove 340 and the positioning block 511 are not completely on the same straight line, the guide inclined surface 341 can guide the positioning block 511 to slide to the bottom of the positioning groove 340, reducing operation time.

[0024] 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 by this utility model. 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.
