Description

Technical Field

[0001] This utility model belongs to the technical field of reaction vessel bodies, specifically relating to an acrylic resin preparation reaction vessel. Background Technology

[0002] The acrylic resin preparation reactor is a core reaction equipment specifically designed for the production of acrylic resins. Its main function is to provide a stable reaction environment for the polymerization reaction of acrylic monomers (such as acrylic acid, methyl methacrylate, etc.) with raw materials such as initiators and solvents, realizing the entire process from raw material mixing to the production of finished resin products.

[0003] The existing resin reactor's stirring fan blades and the liquid level in the tank lack a linkage feedback mechanism. Not only is it impossible to intuitively view the liquid level, but when the liquid level drops below the preset height during the reaction, the corresponding fan blades continue to run according to the original instructions, resulting in idling and wasting motor energy. Utility Model Content

[0004] The purpose of this invention is to provide an acrylic resin preparation reactor, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An acrylic resin preparation reactor includes a liquid level detection component, which includes an air bladder sphere. A marker column is fixedly connected to the upper end of the air bladder sphere. The marker column passes through a top opening. A limiting component for restricting the displacement path of the marker column is provided at the upper end of the top opening. The top opening is located in the reactor body assembly. A fan blade start / stop component includes a rotating main shaft. A fan blade assembly for uniformly mixing the liquid is provided at the outer end of the rotating main shaft. A linkage component for deforming according to the liquid level is assembled at the inner end of the fan blade assembly. Multiple anti-fall support rings arranged vertically and equidistantly are fixedly connected to the outer end of the rotating main shaft.

[0007] As a preferred embodiment of this utility model, the limiting component includes a semi-circular pull block, which is fixedly connected to the upper side of the top opening. The marker post is vertically slidably connected in the vertical slide rail, and the upper end of the marker post is fixedly connected to the semi-circular pull block.

[0008] As a preferred embodiment of this utility model, the vessel assembly includes a reactor body, with a motor fixedly connected to the upper end of the reactor body, and the output end of the motor extending into the reactor body.

[0009] As a preferred embodiment of this utility model, the fan blade assembly includes three inner sleeves, which are fixedly connected to the outside of the rotating main shaft in a vertical and equidistant manner. An outer sleeve is fitted on the outer end of the inner sleeve, and multiple streamlined fan blades are fixedly connected to the outer end of the outer sleeve. The multiple streamlined fan blades are arranged in a ring at equal intervals, and multiple anti-fall support rings are respectively supported on the lower end of the corresponding inner sleeve.

[0010] As a preferred embodiment of this utility model, the linkage component includes an airbag ring sleeve, which is sleeved outside the inner sleeve cylinder and located on the upper side of the outer sleeve cylinder. The linkage component is disposed between the inner sleeve cylinder and the outer sleeve cylinder. An elastic connecting rope is fixedly connected to the lower end of the airbag ring sleeve.

[0014] 1. In this solution, the liquid level detection component is driven by the buoyancy of the air bladder, eliminating the need for an additional power source and effectively reducing energy consumption and equipment operating costs. The combination of the vertical slide rail and the semi-circular pull block in the limiting component can accurately constrain the movement trajectory of the marker column, preventing deviation or detachment and ensuring the accuracy of liquid level detection. Operators can intuitively grasp the remaining amount of raw materials through the position of the marker column and replenish raw materials in a timely manner or control the reaction progress.

[0015] 2. The fan blade start-stop component realizes automatic start and stop of the fan blade according to the liquid level through the linkage component.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an acrylic resin preparation reactor, comprising,

[0025] The liquid level detection component includes an air bladder 10, which is made of fluororubber that is resistant to resin corrosion. A marker column 11 is fixedly connected to the upper end of the air bladder 10. The marker column 11 is made of 304 stainless steel and passes through a top opening 12. A limiting component 13 for limiting the displacement path of the marker column 11 is provided at the upper end of the top opening 12. The top opening 12 is located in the vessel body assembly 14.

[0026] The fan blade start-stop component includes a rotating main shaft 20, with a fan blade assembly 21 for uniformly mixing the liquid at the outer end of the rotating main shaft 20, and a linkage assembly 22 for deforming according to the liquid level at the inner end of the fan blade assembly 21. Multiple anti-fall support rings 23 arranged vertically and equidistantly are fixedly connected to the outer end of the rotating main shaft 20.

[0027] Furthermore, the limiting component 13 includes a semi-circular pull block 132, which is fixedly connected to the upper side of the top opening 12. The marker post 11 is vertically slidably connected in the vertical slide rail 131, and the upper end of the marker post 11 is fixedly connected to the semi-circular pull block 132.

[0028] The vessel assembly 14 includes a reactor body 141, with a motor 142 fixedly connected to the upper end of the reactor body 141, and the output end of the motor 142 extending into the reactor body 141.

[0029] It should be noted that the motor 142 is installed at the top center of the reactor body 141 via a shock-absorbing base, and its output end is fixed to the top of the rotating main shaft 20 via a coupling, with a dustproof sealing gasket at the connection.

[0030] During use, when the raw material is injected into the reactor body 141, the liquid level detection component is activated. The air bladder 10 floats upward due to the buoyancy generated by the raw material, and the marker column 11 fixed at the upper end of the air bladder 10 is simultaneously driven upward. The marker column 11 passes through the top opening 12 on the reactor body assembly 14, and its movement is always within the constraint range of the limiting component 13. The vertical slide rail 131 in the limiting component 13 provides a vertical sliding path for the marker column 11, preventing the marker column 11 from shifting or shaking. The semi-circular pull block 132 fixed at the upper end of the marker column 11 and the semi-circular pull block 132 fixed on the upper side of the top opening 12 are... The pull blocks 132 work together. When the indicator column 11 rises to its maximum stroke with the liquid level, the semi-circular pull block 132 will restrict its further upward movement, preventing the indicator column 11 from detaching from the vertical slide rail 131. As the preparation process progresses and the raw materials are consumed, the liquid level gradually decreases. The air bladder sphere 10 loses its corresponding buoyancy and sinks downward, simultaneously pulling the indicator column 11 vertically downward along the vertical slide rail 131. The operator can intuitively grasp the raw material liquid level in the reactor body 141 by observing the position change of the indicator column 11, and it is easy to disassemble. Throughout the process, the limiting component 13 continuously ensures the stable operation of the liquid level detection component, ensuring the accuracy of liquid level detection.

[0031] Example 2

[0032] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a fan blade assembly 21 including three inner sleeve shafts 211. The airbag ring 221 of the linkage assembly 22 is made of elastic rubber. The three inner sleeve shafts 211 are fixedly connected to the outside of the rotating main shaft 20 in a vertical and equidistant state. An outer sleeve shaft 212 is sleeved on the outer end of the inner sleeve shaft 211. Multiple streamlined fan blades 213 are fixedly connected to the outer end of the outer sleeve shaft 212. The multiple streamlined fan blades 213 are arranged in a ring at equal intervals. Multiple anti-fall support rings 23 are respectively supported on the lower end of the corresponding inner sleeve shaft 211.

[0033] Specifically, the linkage component 22 includes an airbag sleeve 221, which is fitted over the inner sleeve 211 and located on the upper side of the outer sleeve 212. The linkage component 22 is disposed between the inner sleeve 211 and the outer sleeve 212. An elastic connecting rope 222 is fixedly connected to the lower end of the airbag sleeve 221. The elastic connecting rope 222 is made of high-elasticity polyester fiber rope. An upper opening groove 223 is provided on the side end of the outer sleeve 212. The inner end of the upper opening groove 223 is fixedly connected to the inner sleeve 212. The inner block 224 has a self-resetting rotating shaft 225 installed on its side end. The outer end of the self-resetting rotating shaft 225 is connected to a special-shaped buckle rod 226. The outer end of the inner sleeve 211 has a special-shaped buckle groove 227. The special-shaped buckle groove 227 and the special-shaped buckle rod 226 are intermittently engaged. The elastic connecting rope 222 is fixedly connected between the airbag ring 221 and the special-shaped buckle rod 226. The front end of the special-shaped buckle rod 226 is a wedge-shaped structure that matches the special-shaped buckle groove 227.

[0034] During use, after the motor 142 at the upper end of the reactor body 141 is started, its output end drives the main rotating shaft 20 to rotate. The three inner sleeve cylinders 211, which are vertically and equidistantly fixed on the outer side of the main rotating shaft 20, rotate synchronously. The multiple anti-fall support rings 23 at the outer end of the main rotating shaft 20 always support the lower end of the corresponding inner sleeve cylinder 211 to prevent the inner sleeve cylinder 211 from falling off or shifting during operation. The linkage component 22 between the inner sleeve cylinder 211 and the outer sleeve shaft 212 will control the start and stop of the fan blade assembly 21 according to the liquid level. When the liquid level rises, the air bladder ring 221 expands under the action of the liquid level, and the elastic connecting rope 222 fixed at its lower end is pulled. The special-shaped buckle rod 226 connected to the other end of the elastic connecting rope 222 is subjected to force and rotates around the self-resetting rotating shaft 225 installed on the side of the inner block 224. The inner block 224 is fixed in the upper opening groove 223, which is opened on the outside. At the side end of the sleeve shaft 212, the irregularly shaped locking rod 226 rotates and engages with the irregularly shaped locking groove 227 opened at the outer end of the inner sleeve shaft 211. At this time, the rotating inner sleeve shaft 211 drives the outer sleeve shaft 212 to rotate through the irregularly shaped locking rod 226. The streamlined fan blades 213, which are fixed at equal intervals in annular shape at the outer end of the outer sleeve shaft 212, rotate synchronously to stir the raw materials. When the liquid level drops, the airbag ring 221 contracts, the tension of the elastic connecting rope 222 weakens, and the self-resetting rotating shaft 225 drives the irregularly shaped locking rod 226 to reset, so that it disengages from the irregularly shaped locking groove 227. The outer sleeve shaft 212 and the streamlined fan blades 213 stop rotating, realizing that the fan blade assembly 21 automatically starts and stops according to the liquid level. The fan blade starting and stopping component realizes the automatic starting and stopping of the fan blades with the liquid level through the linkage component 22. When the liquid level is insufficient, the streamlined fan blades 213 stop rotating, avoiding energy waste and component wear caused by idling, and extending the service life of the outer sleeve shaft 212 and other components.
