Description
Technical Field
[0001] This utility model relates to the field of polyester resin processing technology, specifically to a high-speed dispersion device for the synthesis of high-temperature resistant polyester resin. Background Technology
[0002] High-temperature resistant polyester resins typically refer to unsaturated polyester resins that maintain good physical and mechanical properties and corrosion resistance at high temperatures. Currently, in the specific process of synthesizing high-temperature resistant polyester resins, in order to ensure the uniformity of the mixing of various components, a mature high-speed disperser is usually used for stirring. The high-speed disperser is a type of mixer. In specific use, it can generate strong turbulence in local areas through its own high-speed agitator, thereby effectively dispersing and emulsifying the materials and ensuring the mixing effect of various chemical materials.
[0003] However, the high-speed dispersers currently in use also have some problems that need to be improved. For example, there is a lack of means to deal with the pungent odor generated by the material reaction during the stirring process, and the production environment is easily polluted. Secondly, the friction during high-speed stirring will generate heat, and the heat will further accelerate the production of the pungent odor generated by the material reaction. In summary, in view of the problems existing in the prior art, this application will provide a high-temperature resistant high-speed disperser for the synthesis of polyester resin. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a high-speed dispersion device for the synthesis of high-temperature resistant polyester resin, which solves the problems mentioned in the background section.
[0005] This utility model provides the following technical solution: a high-speed dispersion device for high-temperature resistant polyester resin synthesis, including a base, a material tank, and a hydraulic lifting mechanism installed on one side of the base. The output end of the hydraulic lifting mechanism is driven to a stirring transmission mechanism. One side of the stirring transmission mechanism is driven to a stirring structure capable of stirring the internal space of the material tank. A hollow ring box is installed at the bottom of the shell on one side of the stirring transmission mechanism and is movably fitted with the top structure of the stirring structure. Several fan blades are installed on the surface of the top of the stirring structure and are movably fitted inside the hollow ring box.
[0006] The top and bottom of the hollow ring box are respectively equipped with gas output pipes and flow valve pipes. The other side of the base is provided with heat conduction pipes and composite platform. The heat conduction pipes are installed on the top of the composite platform and can contact the bottom surface of the material barrel for heat conduction. One end of the heat conduction pipes is installed between the rear end of the hollow ring box and the rear end of the hollow ring box.
[0007] Specifically, the number of fan blades is six, which are equidistantly distributed along the circumference of the stirring structure, and the output direction of the fan blades is towards the top space of the hollow ring box.
[0008] The heat-conducting pipe is composed of several S-shaped pipes laid flat and assembled in sequence to ensure sufficient contact area during subsequent heat conduction. The end of the S-shaped pipe closest to the rear end of the base is connected to the end of the elastic transition pipe, while the end of the S-shaped pipe closest to the front end of the base is an open space.
[0009] Selectedly, one-way valves and regulating valves are respectively installed at one end and the middle part of the elastic transition tube to meet the usage requirements of different states, and the other end of the elastic transition tube is fitted into the bottom inner side of the rear end of the hollow ring box.
[0010] Selectedly, the bottom of the hollow ring box is equipped with a drainage hood for the drainage valve tube assembly. The drainage hood adopts a conical tube structure and is used to initially guide the drainage air and expand the drainage range.
[0011] Preferably, the gas output pipe includes an annular pipe, a transition branch pipe is installed between the bottom of the annular pipe and the top of the hollow annular box, and an output branch pipe is installed at the top of the annular pipe. The gas output pipe guides the gas output by the fan blades to the existing waste gas treatment equipment, reducing the impact of the pungent odor of the mixed materials on the processing environment.
[0012] The composite platform includes a movable plate, with guide shafts mounted on the other side of the base on both sides of the movable plate. The bottom surfaces of several S-shaped tubes are mounted on the top surface of the movable plate. Buffer springs are fitted on the outer sides of the guide shafts, with the two ends of the buffer springs connected to the bottom of the movable plate and the surface on the other side of the base, respectively. As a platform capable of lifting and moving, the composite platform can adaptively connect the heat-conducting pipes to the material container, avoiding rigid collisions.
[0013] Selectedly, a damping block is installed on the top of the guide shaft. During the slight vibration of the material bucket being stirred, the damping block can reciprocate and contact the movable plate to buffer the vibration. Both sides of the movable plate are fitted with negative pressure suction cups that can negatively attract the bottom surface of the material bucket. Using the negative pressure suction cups as a connection transition can increase the connection between the material bucket and the composite platform, which helps to stabilize the material bucket under stirring conditions.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model comprises a hollow ring box, multiple fan blades, a gas output pipe, and a diversion valve to form a negative pressure diversion device. When used in combination with a stirring structure and a stirring transmission mechanism, the multiple fan blades can generate pressurized air in the hollow ring box and deliver it to the gas output pipe without interfering with the rotation and stirring of the stirring structure. This creates a negative pressure diversion environment inside the hollow ring box. Subsequently, the hollow ring box can actively divert the pungent odor of the raw material reaction that extends from the top of the material tank through the diversion valve, reducing the amount of pungent odor of the raw material reaction that extends into the processing environment.
[0016] 2. This utility model consists of a linkage cooling device composed of heat-conducting pipes, an elastic transition pipe, and a composite platform. During subsequent use, the elastic transition pipe serves as a transition channel, allowing the air inside the heat-conducting pipes to be affected by the negative pressure flow effect inside the hollow ring box, thereby accelerating the airflow inside the pipes and improving the heat conduction and heat dissipation effect of the heat-conducting pipes on the material bucket, and promptly treating the waste heat generated by stirring friction.

[0023] 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.
[0024] Example 1
[0025] Please see Figure 1-3 A high-speed dispersion device for high-temperature resistant polyester resin synthesis includes a base 1, a material tank 5, a hydraulic lifting mechanism 2 installed on one side of the base 1, a stirring transmission mechanism 3 connected to the output end of the hydraulic lifting mechanism 2, a stirring structure 4 connected to one side of the stirring transmission mechanism 3 to stir the internal space of the material tank 5, a hollow ring box 6 installed at the bottom of the shell on one side of the stirring transmission mechanism 3 and movably fitted with the top structure of the stirring structure 4, and several fan blades 7 movably fitted inside the hollow ring box 6 installed on the surface of the top of the stirring structure 4.
[0026] The number of fan blades 7 is specifically six and they are equidistantly distributed along the circumference of the stirring structure 4, and the output direction of the fan blades 7 is towards the top space of the hollow ring box 6.
[0027] The top and bottom of the hollow ring box 6 are respectively equipped with a gas output pipe 8 and a diversion valve pipe 9. The gas output pipe 8 includes an annular pipe 81. A transition branch pipe 83 is installed between the bottom of the annular pipe 81 and the top of the hollow ring box 6. An output branch pipe 82 is installed at the top of the annular pipe 81. The gas output pipe 8 guides the gas output by the fan blade 7 to the existing waste gas treatment equipment to reduce the impact of the pungent odor of the mixed materials on the processing environment.
[0028] On the other side of the base 1, a heat-conducting pipe 11 and a composite platform 10 are provided. The heat-conducting pipe 11 is installed on the top of the composite platform 10 and can contact the bottom surface of the material barrel 5 for heat conduction. An elastic transition pipe 12 is installed between one end of the heat-conducting pipe 11 and the rear end of the hollow ring box 6. A flow hood 13 for the flow valve pipe 9 is installed at the bottom of the hollow ring box 6. The flow hood 13 adopts a conical tube structure and is used to initially guide the flow of air and expand the flow range.
[0029] The heat-conducting pipe fitting 11 is composed of several S-shaped pipes laid flat in sequence to ensure sufficient contact area during subsequent heat conduction. The end of the S-shaped pipe closest to the rear end of the base 1 is connected to one end of the elastic transition pipe 12. The end of the S-shaped pipe closest to the front end of the base 1 is an open space. One-way valve and regulating valve are respectively installed at one end and the middle part of the elastic transition pipe 12 to meet the usage requirements of different states. The other end of the elastic transition pipe 12 is fitted into the bottom inner side of the rear end of the hollow ring box 6.
[0030] Specific usage process: The output end of the hydraulic lifting mechanism 2 first drives the stirring transmission mechanism 3 and the stirring structure 4 to rise and make way. Then, the material bucket 5 is moved to a position aligned with the stirring structure 4. During the movement of the material bucket 5, its bottom surface gradually contacts the top surface of the heat-conducting pipe 11 and until it completely covers the heat-conducting pipe 11.
[0031] After the material bucket 5 is moved to the designated position, the hydraulic lifting mechanism 2 is turned off. Then, the output end of the hydraulic lifting mechanism 2 automatically resets the stirring transmission mechanism 3 and the stirring structure 4. The stirring structure 4 is fitted into the inside of the material bucket 5 and buried in the raw materials inside the material bucket 5. The stirring transmission mechanism 3 is activated to drive the stirring structure 4, so that the stirring structure 4 can stir and disperse the various raw materials inside the material bucket 5 at high speed.
[0032] When the valve inside the diversion valve pipe 9 and the regulating valve inside the elastic transition pipe 12 are opened, the stirring structure 4 will drive multiple fan blades 7 to rotate synchronously during the rotation process. This will cause multiple fan blades 7 to generate airflow towards the top of the hollow ring box 6 inside the hollow ring box 6 and be discharged through the gas output pipe 8. This will create a negative suction effect inside the hollow ring box 6. Subsequently, the pungent odor of the material reaction that extends from the top of the material bucket 5 will be diverted into the hollow ring box 6 through the diversion hood 13 and the diversion valve pipe 9. It will then be pressurized and transported to the gas output pipe 8 and guided to the existing waste gas treatment equipment. This process will continue indefinitely.
[0033] At the same time, the flexible transition tube 12, as a transition channel, will guide the air inside the heat-conducting pipe 11 into the hollow ring box 6 under the negative suction effect of the hollow ring box 6, thereby accelerating the air flow speed inside the heat-conducting pipe 11, improving the heat dissipation efficiency of the heat-conducting pipe 11 in heat conduction to the material bucket 5, and reducing the amount of pungent odor produced by the material reaction caused by stirring friction heat generation, and so on.
[0034] Example 2
[0035] Please see Figure 4-5The composite platform 10 includes a movable plate 101. Both sides of the movable plate 101 are snapped with guide shafts 102 installed on the other side of the base 1. The bottom surfaces of several S-shaped tubes are installed on the top surface of the movable plate 101. A buffer spring 103 is fitted on the outside of the guide shaft 102, and the two ends of the buffer spring 103 are respectively connected to the bottom of the movable plate 101 and the surface on the other side of the base 1. As a platform that can be lifted and moved, the composite platform 10 can drive the heat-conducting pipe 11 to make an adaptive connection with the material bucket 5 to avoid rigid collision.
[0036] A damping block is installed on the top of the guide shaft 102. During the slight vibration of the material tank 5 being stirred, the damping block can reciprocate to contact the movable plate 101 to buffer the vibration. Both sides of the movable plate 101 are fitted with negative pressure suction cups 104 that can negatively attract the bottom surface of the material tank 5. Using the negative pressure suction cups 104 as a connection transition can increase the connection between the material tank 5 and the composite platform 10, which helps to stabilize the material tank 5 in the stirring state.
[0037] Specific usage process: As the material bucket 5 moves and its bottom surface gradually comes into contact with the top surface of the heat-conducting pipe 11, the movable plate 101, supported by the buffer spring 103, drives the heat-conducting pipe 11 to make elastic contact with the bottom surface of the material bucket 5, avoiding rigid collision between the material bucket 5 and the heat-conducting pipe 11. After the material bucket 5 has moved, the heat-conducting pipe 11 will be pressed against the bottom surface of the material bucket 5 by the top pressure of the movable plate 101 and the buffer spring 103, creating good conditions for subsequent heat conduction and heat dissipation of the material bucket 5.
[0038] During the stirring process inside the material tank 5, the vibrations it experiences are simultaneously transmitted to the heat-conducting pipe 11 and the movable plate 101. The movable plate 101 then reciprocates with the damping block set on the top of the guide shaft 102, providing damping and buffering for the material tank 5, thereby further optimizing the overall performance of the equipment.
