Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to an automatic cleaning device for reaction vessels. Background Technology

[0002] In numerous industries such as chemical, pharmaceutical, and food processing, reaction vessels are widely used equipment for various chemical reactions or material mixing operations. With prolonged use, various residues gradually accumulate on the inner walls of the reaction vessel, such as chemical crystals, precipitates, and dirt. These residues not only affect the normal operation of the reaction vessel and reduce reaction efficiency but may also adversely impact the quality of subsequent products. Traditional reaction vessel cleaning methods primarily rely on manual operation, requiring workers to enter the vessel and use tools such as brushes and high-pressure water guns for cleaning. However, this method has many drawbacks: firstly, the internal space of a reaction vessel is usually confined and the environment harsh, making operation difficult and posing safety hazards for workers; secondly, manual cleaning is inefficient, the cleaning quality is difficult to guarantee, and for some stubborn residues, manual cleaning rarely achieves the desired cleaning effect. Utility Model Content

[0003] Therefore, to address the aforementioned problems, this utility model proposes an automatic cleaning device for reaction vessels. It solves the technical problem of poor cleaning effect in reaction vessels.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic cleaning device for a reaction vessel includes a frame, a clamping assembly mounted on the frame, a lifting assembly mounted on the frame, and a cleaning assembly mounted on the lifting assembly. The lifting assembly includes a drive component mounted on a support and a lifting plate connected to the drive component. The cleaning assembly includes a first motor mounted on the lifting plate, a rotating rod connected to the output end of the first motor, at least one brush body rotatably mounted on the rotating rod, a cylinder mounted inside the rotating rod, a push plate mounted at the output end of the cylinder, and at least one elongated hole opened on the rotating rod. The push plate has a protruding block extending from the elongated hole, and a connecting rod is hinged to the protruding block. The other end of the connecting rod is hinged to the brush body. The lifting plate has two water spray plates located on both sides of the rotating rod, and the water spray plates have multiple spray nozzles.

[0006] Further:

[0007] The brush body includes a first support rod rotatably connected to the rotating rod, a sliding groove disposed in the first support rod, a spring disposed in the sliding groove, a sliding rod connected to the other end of the spring, and brush bristles disposed at the end of the sliding rod. The sliding rod slides along the sliding groove under the action of the spring, and the connecting rod is rotatably connected to the first support rod.

[0008] The brush body includes a second support rod rotatably connected to the rotating rod, a slot at one end of the second support rod, a second motor in the slot, a brush rod connected to the output end of the second motor, and brush bristles at the end of the brush rod. The connecting rod is rotatably connected to the second support rod.

[0009] The driving component includes a third motor mounted on the frame, a rotating shaft mounted on the output end of the third motor, a driving gear mounted on the rotating shaft, a lead screw mounted on the frame, a driven gear sleeved on the lead screw, and a slider threadedly connected to the lead screw. The driven gear meshes with the driving gear, and one end of the lifting plate is connected to the slider.

[0010] The frame is provided with a guide rod, and the other end of the lifting plate passes through the guide rod and slides along the guide rod.

[0011] The clamping assembly includes a U-shaped plate, a screw passing through the U-shaped plate, and a clamping plate located on the top of the screw. Adjusting the screw can move the clamping plate.

[0012] The frame is equipped with a water tank, which is connected to the spray plate via a hose, and the water tank is connected to a booster pump.

[0013] The spray nozzles are tilted downwards.

[0014] The bottom of the frame is equipped with universal self-locking wheels.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] In this invention, the brush body is expandable and retractable, extending after entering the reactor to adapt to reactors with different opening shapes and sizes. The angle of the brush body can also be adjusted as needed to better conform to the inner wall of the reactor for cleaning, improving the cleaning effect. The lifting component can move the cleaning component up and down, cooperating with the rotating rod to rotate the brush body, achieving cleaning at different heights within the reactor and ensuring that every corner inside the reactor is cleaned. When not in use, the cleaning component is located outside the reactor, not occupying space inside. Furthermore, the sliding rod slides along the groove under the action of a spring, allowing the bristles to automatically adjust their extension length according to the shape and roughness of the reactor's inner wall, thus better... The design adapts well to the inner walls of reactors with different shapes and conditions, improving the adaptability and effectiveness of cleaning. Furthermore, the second motor drives the brush rod to rotate, allowing the bristles to rotate more flexibly, thereby enhancing the cleaning ability against stubborn residues on the reactor's inner wall, suitable for situations with high cleaning requirements. Additionally, the drive mechanism offers advantages of smooth transmission and high precision, ensuring the stability and accuracy of the cleaning assembly during lifting. The guide rod prevents the lifting plate from shifting during lifting, improving the stability and reliability of the lifting assembly. Finally, the clamping plate can be easily moved by adjusting the screw, stably clamping the reactor onto the frame, making operation simple, convenient, and secure. Attached Figure Description
