A cleaning device for a reaction kettle

Abstract

This application discloses a cleaning device for a reactor, comprising an annular plate. The upper surface of the annular plate has annularly arranged grooves. A set of connecting shafts is fixedly connected to the inner wall of each groove. The ends of each set of connecting shafts, close to each other, are rotatably connected to a connecting pipe. One end of each connecting pipe is connected to a nozzle. A circular plate is disposed inside the annular plate. An annularly arranged sleeve is fixedly connected to the outer surface of the circular plate. A sliding rod is slidably connected to the inner wall of each sleeve. One end of each sliding rod is hinged to a pull rod. This device, through the cooperation of an electric push rod, a circular plate, sleeves, sliding rods, and pull rods, utilizes the reciprocating extension and retraction of the electric push rod to drive the connecting pipes to reciprocate. Simultaneously, the nozzles reciprocate up and down, causing the water jets to be sprayed obliquely onto the inner wall of the reactor, thereby avoiding blind spots in cleaning and further improving the cleaning effect inside the reactor.

Description

Technical Field

[0001] This application relates to the field of reactor cleaning technology, and in particular to a reactor cleaning device. Background Technology

[0002] As core equipment in the chemical and pharmaceutical industries, reaction vessels are prone to scale, oil stains and other contaminants remaining on the inner wall, stirring shaft and bottom of the vessel after long-term use. If cleaning is not thorough, it will lead to cross-contamination of subsequent batches of materials and affect product quality. At the same time, stubborn scale will reduce the heat transfer efficiency of the reaction vessel and increase energy consumption.

[0003] Current cleaning devices use a fixed angle for the water jet from the nozzles. For the curved transition area between the bottom and the wall of the reactor, the fixed angle of the water jet cannot conform to the curved surface, resulting in an uncleaned zone. Residual viscous materials accumulate here and are difficult to remove, thus reducing the cleaning effect. To address this issue, we propose a cleaning device for reactors. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cleaning device for a reaction vessel includes an annular plate. The upper surface of the annular plate has annularly arranged grooves. A set of connecting shafts is fixedly connected to the inner wall of each groove. The ends of each set of connecting shafts, close to each other, are rotatably connected to a connecting pipe. One end of each connecting pipe is connected to a nozzle. A circular plate is disposed inside the annular plate. An annularly arranged sleeve is fixedly connected to the outer surface of the circular plate. A sliding rod is slidably connected to the inner wall of each sleeve. One end of each sliding rod is hinged to a pull rod.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] 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.

[0018] Please see Figure 1-3 In this utility model, a cleaning device for a reaction vessel includes an annular plate 1. The upper surface of the annular plate 1 has annularly arranged grooves 7. Each groove 7 has a set of connecting shafts 14 fixedly connected to its inner wall. The ends of each set of connecting shafts 14 that are close to each other are rotatably connected to a connecting pipe 15. One end of each connecting pipe 15 is connected to a nozzle 6. The connecting shafts 14 can stabilize the connecting pipe 15 inside the groove 7. The outer surface of each connecting pipe 15 is connected to a water supply pipe 8. Each water supply pipe 8 is retractable and can supply water to an external water source, allowing the water to enter the connecting pipe 15 and be sprayed out from the nozzle 6. Each nozzle 6 is a high-pressure nozzle, which can further enhance the cleaning effect of the water jet.

[0019] An annular plate 1 contains a circular plate 2. A ring of sleeves 12 are fixedly connected to the outer surface of the circular plate 2. Each sleeve 12 has a sliding rod 13 slidably connected to its inner wall. One end of each sliding rod 13 is hinged to a pull rod 9, and the other end of each pull rod 9 is hinged to the other end of a connecting pipe 15. A driving structure is located above the circular plate 2. The driving structure includes an electric push rod 4 mounted on the upper surface of the circular plate 2. When the electric push rod 4 is activated, it reciprocates, causing the circular plate 2 to descend. The circular plate 2 then moves the sleeves 12 downwards, and the sleeves 12 move the sliding rods 13 downwards. The other end of the sliding rod 13 pulls one end of the pull rod 9 downwards, and the other end of the pull rod 9 pulls the connecting pipe 15 to rotate around the connecting shaft 14. At this time, the nozzle 6 deflects upwards to spray water, and conversely, it deflects downwards to spray water. This allows the water jet from the nozzle 6 to conform to the curved surface of the reactor, preventing blind spots and ensuring effective cleaning.

[0020] The top of the electric push rod 4 is fixedly connected to a cross plate 5, and the bottom surface of the cross plate 5 is fixedly connected to a ring of uprights 3. The bottom end of each upright 3 is connected to the upper surface of the ring plate 1. By using the cooperation between the uprights 3 and the cross plate 5, the electric push rod 4 can be supported, thereby ensuring its stable operation.

[0021] Each sleeve 12 has a set of limiting grooves 11 on its outer surface. Each limiting groove 11 has a slider 10 slidably connected to its inner wall. One end of each slider 10 is connected to the outer surface of the slide rod 13. By using the cooperation of the limiting grooves 11 and the sliders 10, the movement of the slide rod 13 can be limited, preventing it from separating from the sleeve 12.

[0022] The working principle of this application is as follows: When in use, this device is inserted into the reactor, and then water is injected into the water supply pipe 8 through the external pipe. The water will enter the connecting pipe 15 and be sprayed out from the nozzle 6. Then, the electric push rod 4 is activated to reciprocate and extend. The extension and retraction of the electric push rod 4 will push the circular plate 2 down, and the circular plate 2 will drive the sleeve 12 to move down. At the same time, the sleeve 12 will drive the sliding rod 13 to move down. The other end of the sliding rod 13 will pull one end of the pull rod 9 down, and the other end of the pull rod 9 will pull the connecting pipe 15 to rotate around the connecting shaft 14. At this time, the nozzle 6 will deflect upward to spray water, and conversely, the nozzle 6 will deflect downward to spray water. This allows the water jet from the nozzle 6 to conform to the curved surface of the reactor, so as to avoid cleaning blind spots and thus ensure the cleaning effect.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
