Description

Technical Field

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

[0002] A reaction vessel is a widely used piece of equipment in industries such as chemical, petroleum, pharmaceutical, dye, and food processing, used to realize physical or chemical reaction processes. It typically consists of a vessel body, a transmission device, a stirrer, heating or cooling devices, and temperature and pressure sensors. When reacting liquid substances, multiple liquid materials are added to the vessel body, and the stirrer agitates them to ensure thorough mixing and reaction. However, during the reaction process, precipitation may occur. After the reaction solution is removed, residues of solution and precipitate remain in the vessel body, requiring cleaning. This is usually done by workers circulating water into the vessel, which is inefficient, labor-intensive, and results in only a limited degree of cleaning. Utility Model Content

[0003] The purpose of this application is to provide a self-cleaning reactor that can clean the inside of the reactor after the solution is transferred out, and the cleaning is highly effective and efficient.

[0004] The self-cleaning reactor provided in this application adopts the following technical solution:

[0005] A self-cleaning reactor, comprising:

[0006] The vessel body;

[0007] A stirring shaft is inserted into the vessel body and rotatably connected to the vessel body; the stirring shaft has a water passage hole along its axis.

[0008] A plurality of stirring blades are provided, all of which are disposed in the vessel body and fixed on the stirring shaft. Each stirring blade is provided with a cleaning hole, and each cleaning hole is connected to the water passage hole.

[0009] A drive assembly is used to drive the stirring shaft to rotate;

[0010] A water pipe is rotatably connected to the stirring shaft and communicates with the water inlet.

[0011] Optionally, each of the cleaning holes is provided with a one-way valve.

[0012] Optionally, the drive assembly includes a first gear, a second gear, and a drive member. The first gear is fixed on the stirring shaft, the second gear meshes with the first gear, and the drive member is used to drive the second gear to rotate.

[0013] Optionally, a lifting assembly is included, which includes a lifting plate and a telescopic component. The lifting plate is sleeved on the stirring shaft and rotatably connected to the stirring shaft. One end of the telescopic component is fixed to the vessel body and the other end is fixed to the lifting plate. The driving component is fixed to the lifting plate.

[0014] Optionally, an annular groove is provided on the stirring shaft, and the lifting plate is inserted into the annular groove.

[0015] Optionally, it also includes a clamp, which is fixed to the water pipe. The clamp is inserted into the water passage hole and a bearing is provided between the clamp and the inner wall of the water passage hole. The clamp is rotatably connected to the stirring shaft through the bearing.

[0016] This application utilizes water passages on the stirring shaft and cleaning holes on the stirring blades. High-pressure water flows through the water passages into the cleaning holes and is then sprayed out, effectively cleaning the inner wall of the vessel. During the cleaning process, the stirring shaft rotates and moves up and down, causing the stirring blades to move vertically, further covering and cleaning the inner wall of the vessel. This increases the cleaning effect and speed. Furthermore, after the solution has drained from the vessel, water can be directly supplied to the water pipes, reducing manual operation and labor costs. Attached Figure Description

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0022] A self-cleaning reactor, as described in the reference Figure 1The apparatus includes a vessel body 1, a stirring shaft 2, stirring blades 3, and a drive assembly 4. A feed inlet 11 is located on the top of the vessel body 1, and a discharge outlet 12 is located on the bottom surface of the vessel body 1. Both the discharge outlet 12 and the feed inlet 11 can be freely opened and closed. In this embodiment, the discharge outlet 12 and the feed inlet 11 are opened and closed freely via a solenoid valve. Liquid materials enter the vessel body 1 through the feed inlet 11 and mix and react with other liquid materials within the vessel body 1.

[0023] A stirring shaft 2 is inserted into and rotatably connected to the vessel body 1. Specifically, the stirring shaft 2 is vertically inserted into the vessel body 1. Several stirring blades 3 are provided, all fixed on the stirring shaft 2 and disposed inside the vessel body 1. A drive assembly 4 is used to drive the stirring shaft 2 to rotate. When several liquid materials are introduced into the vessel body 1, the drive assembly 4 operates, driving the stirring shaft 2 to rotate, thereby driving the stirring blades 3 to rotate, so that the stirring blades 3 stir the several liquid materials, making them fully mixed and reacted.

[0024] Furthermore, the stirring blades 3 are arranged in groups of three, and several groups are set up. Each group of stirring blades 3 is circumferentially distributed on the stirring shaft 2. Several groups of stirring blades 3 are evenly spaced along the vertical direction of the stirring shaft 2. By evenly spaced several groups of stirring blades 3 along the axial direction of the stirring shaft 2, the liquid material is stirred at different depths, thereby further increasing the uniformity of the mixing of several liquid materials.

[0025] Reference Figure 1 and Figure 2 The stirring shaft 2 has a water passage hole 21 along its own axis, and the water passage hole 21 passes through the upper end of the stirring shaft 2. Each stirring blade 3 has a cleaning hole 31, which is connected to the water passage hole 21. A water pipe 7 is installed at the top of the stirring shaft 2. The water pipe 7 is inserted into the water passage hole 21 and rotates with the stirring shaft 2. The end of the water pipe 7 away from the stirring shaft 2 is connected to a water source. After the liquid material in the vessel 1 has reacted, the resulting solution flows out through the discharge port 12 and the discharge port 12 is closed. At this time, high-pressure water is injected into the water passage hole 21 through the water pipe 7. The high-pressure water flows into the cleaning hole 31 through the water passage hole 21 and sprays out through the cleaning hole 31, spraying onto the inner wall of the vessel 1, thereby cleaning the inner wall of the vessel 1. At the same time as water is flowing, the stirring shaft 2 rotates, driving the stirring blade 3 to rotate, thereby driving the high-pressure water to spray and wash the inner wall of the vessel 1 around the perimeter. In this embodiment, a drain outlet (not shown in the figure) is provided on the bottom surface of the vessel body 1. The drain outlet is used to discharge sewage, and the opening and closing of the drain outlet can also be controlled by a solenoid valve.

[0026] Reference Figure 3Specifically, a clamp 5 is fixedly fitted on the water pipe 7. The water pipe 7 is inserted into the water passage hole 21 and the clamp 5 is located inside the water passage hole 21. A bearing 6 is provided between the clamp 5 and the inner wall of the water passage hole 21. The clamp 5 is rotatably connected to the stirring shaft 2 through the bearing 6, thereby realizing the rotatable connection between the water pipe 7 and the stirring shaft 2. During the rotation of the stirring shaft 2, the water pipe 7 remains fixed, thereby reducing the possibility of the water pipe 7 getting tangled.

[0027] Furthermore, a one-way valve 8 is fixedly installed in each cleaning hole 31. The one-way valve 8 is used to restrict the flow direction of water. High-pressure water is sprayed into the inner wall of the vessel 1 through the one-way valve 8, and the solution in the vessel 1 is restricted by the one-way valve 8 to flow into the cleaning hole 31. In this way, during the stirring of several liquid materials, the situation of liquid materials flowing into the water passage hole 21 and causing liquid material waste is reduced.

[0028] The drive assembly 4 includes a first gear 41, a second gear 42, and a drive member 43. In this embodiment, the drive member 43 is a motor. The first gear 41 is fixedly sleeved on the outer wall of the stirring shaft 2. The second gear 42 meshes with the first gear 41 and is fixed at the output end of the drive member 43. The drive member 43 drives the second gear 42 to rotate, thereby driving the first gear 41 to rotate, thus driving the stirring shaft 2 to rotate.

[0029] Furthermore, a lifting assembly 9 is provided on the vessel body 1. The lifting assembly 9 is used to drive the stirring shaft 2 to reciprocate vertically. By reciprocating vertically, the stirring shaft 2 increases the uniformity of mixing of several liquid materials, and enhances the cleaning effect of the vessel body 1 during cleaning. Since there is a gap between adjacent sets of stirring blades 3, there may be areas that are not sprayed when the water is sprayed. The lifting assembly 9 drives the stirring blades 3 to move vertically, thereby thoroughly cleaning the vessel body 1 and further increasing the cleanliness of the vessel body 1.

[0030] The lifting assembly 9 includes a lifting plate 91 and a telescopic member 92. In this embodiment, the telescopic member 92 is an electric telescopic rod. The lifting plate 91 is sleeved on the stirring shaft 2 and rotatably connected to it. One end of the telescopic member 92 is fixed to the vessel body 1, and the other end is fixed to the lifting plate 91. The driving member 43 is fixed to the lifting plate 91. By extending and retracting the telescopic member 92, the lifting plate 91 moves up and down, thereby driving the stirring shaft 2 and the driving member 43 to move up and down, thus driving the stirring blades 3 to move up and down.

[0031] Furthermore, an annular groove 22 is provided on the stirring shaft 2. The lifting plate 91 is sleeved on the stirring shaft 2 and inserted into the annular groove 22, thereby restricting the movement of the lifting plate 91 and further increasing the mutual restraint between the lifting plate 91 and the stirring shaft 2 in the vertical direction.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
