Description

TECHNICAL FIELD

[0001] The utility model relates to engineering plastics production equipment technical field, concretely is a kind of preparation device of polyimide composite engineering plastics. BACKGROUND

[0002] Engineering plastics refers to the industrial plastic used as industrial parts or processing tank material, which is a plastic with excellent strength, impact resistance, heat resistance, hardness and aging resistance. In the prior art, a certain amount of wastewater is generated during the preparation of engineering plastics. The impurities contained in the wastewater are generally removed by adding a flocculant, which adsorbs the impurities and then filters out clean water.

[0003] The existing Chinese patent (publication number: CN219807828U) discloses a wastewater treatment device for engineering plastics preparation, which comprises a treatment tank. The bottom end of the treatment tank is provided with a motor. In use, the wastewater is injected into the treatment tank through the wastewater inlet pipe, and then the flocculant is added through the flocculant adding funnel. Then, the motor is started to drive the stirring impeller to rotate, so that the flocculant can react with the wastewater. After stopping stirring, the impurities in the wastewater are flocculated, and then filtered through the filter screen. The filter screen is lifted by the air cylinder, so that the impurities are discharged through the flocculant outlet pipe. At the same time, the delivery pump is started to pump the wastewater below the filter screen to the top of the filter screen for continuous filtration until the impurities in the wastewater are completely filtered. Compared with the existing wastewater treatment equipment.

[0004] In the above-mentioned device, the impurities in the wastewater are mixed with the flocculant by the stirring impeller. However, the angle and shape of the stirring impeller are fixed and cannot be adjusted flexibly according to the actual properties of the wastewater. This results in a decrease in stirring effect when dealing with wastewater with different properties. For example, when dealing with wastewater with high viscosity, the fixed stirring impeller cannot provide sufficient thrust, so that the flocculant cannot be fully mixed with the wastewater, the impurities cannot be flocculated effectively, and the subsequent filtration efficiency and wastewater treatment quality are affected. For wastewater with high density, the stirring range of the existing stirring impeller is limited, and the impurities in different parts of the wastewater cannot be effectively contacted with the flocculant, resulting in incomplete flocculation of part of the impurities and reduction of the treatment capacity and reliability of the entire wastewater treatment system.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-6 The utility model provides a technical scheme: a preparation device for polyimide composite engineering plastics, including processing box 1, including,

[0027] Stirring cylinder 201 is rotationally connected in processing box 1, and a plurality of stirring blades 202 are rotationally connected on both sides of stirring cylinder 201 and are linearly arrayed and equally spaced along the height direction of stirring cylinder 201, one side of stirring blade 202 is connected with connecting shaft, one end of connecting shaft extends into stirring cylinder 201 and is connected with first transmission gear 204, two drive racks 203 are slidingly connected in stirring cylinder 201, and drive rack 203 is meshed with first transmission gear 204.

[0028] In the embodiment, in order to adjust the angle of the stirring blade 202, the two driving racks 203 slide in the stirring drum 201. Since the driving racks 203 are connected with the first transmission gear 204 on the connecting shaft of the stirring blade 202, when the driving racks 203 move, the first transmission gear 204 rotates, the connecting shaft rotates, and finally the angle of the stirring blade 202 is changed. When the processed material has different characteristics, for example, the viscosity is large, the moving direction and distance of the driving rack 203 can be controlled to adjust the stirring blade 202 to a more inclined angle, so that the thrust on the material during stirring is increased, the stirring effect is enhanced, and the material is mixed more uniformly. For materials with high density, the stirring blade 202 can be expanded to a larger shape through corresponding adjustment, thereby expanding the stirring range to ensure that the material is fully stirred at each position and improve the overall stirring efficiency and quality to meet the strict requirements for material mixing uniformity and fullness during the preparation of polyimide composite engineering plastics.

[0030] In the embodiment, when adjusting the angle of the stirring blade 202, when one of the driving racks 203 is driven to move, for example, the driving rack 203 connected with the first connecting rack 301 at the top is driven to move. The movement of the first connecting rack 301 drives the second transmission gear 302 to rotate, and since the second transmission gear 302 is also meshed with the second connecting rack 303, the rotation of the second transmission gear 302 drives the second connecting rack 303 to move in the opposite direction. The other driving rack 203 is connected to the top of the second connecting rack 303, so that the reverse and synchronous movement of the two driving racks 203 is realized.

[0031] The arrangement can drive one of the driving racks 203 through a driving source, and through the transmission of the second transmission gear 302, the two driving racks 203 can work cooperatively to adjust the angle of the stirring blade 202. When facing different characteristics of polyimide composite engineering plastic raw materials, the angle of the stirring blade 202 can be changed more efficiently to meet the needs.

The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302. The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302. The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302. The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302. The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302. The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302. The top of one of the driving racks 203 is connected with the first connecting rack 301, the top of the other driving rack 203 is connected with the second connecting rack 303, and the first connecting rack 301 and the second connecting rack 303 are meshed with the second transmission gear 302.

[0033] In the embodiment, the servo motor 9 at the top is started. The driving end of the servo motor 9 starts to rotate, and drives the transmission belt 11 connected thereto to operate.

[0034] The movement of the transmission belt 11 is transmitted to the first synchronous wheel 10 through the second synchronous wheel 12 in transmission connection with the transmission belt 11. Since the first synchronous wheel 10 is fixedly connected with one end of the stirring cylinder 201, the rotation of the first synchronous wheel 10 drives the stirring cylinder 201 to rotate around the shaft in the processing box 1.

[0035] Referring to Figure 5 and Figure 6 , the top of the stirring cylinder 201 is connected with the mounting plate 4, the driving shaft 5 is rotatably connected in the mounting plate 4, the driving shaft 5 is used to drive the second transmission gear 302 to rotate, one side of the driving shaft 5 is connected with the rotating disc 6, and the rotating disc 6 is inserted with the limiting column 7.

[0036] In the embodiment, the rotating disc 6 is connected with the driving shaft 5, which is used to assist in controlling the rotation and positioning of the driving shaft 5. When it is needed to rotate the driving shaft 5, the rotating state of the rotating disc 6 can be controlled by inserting and pulling out the limiting column 7. For example, in the initial state, the limiting column 7 is inserted into the specific hole position of the rotating disc 6, so as to limit the rotation of the rotating disc 6, at this time, the driving shaft 5 is in the fixed position, and the angle of the stirring blade 202 remains unchanged. When it is needed to adjust the angle of the stirring blade 202, the limiting column 7 is pulled out from the rotating disc 6.

[0037] Referring to Figure 6 , a plurality of limiting holes matched with the limiting column 7 are formed in the rotating disc 6, and the plurality of limiting holes are distributed in the circumferential array at equal intervals with the center of the rotating disc 6 as the center.

[0038] In the embodiment, the plurality of limiting holes in the circumferential array at equal intervals on the rotating disc 6 are used to more accurately position the rotating disc 6 and the driving shaft 5. When the rotating disc 6 is rotated to a specific angle, that is, the stirring blade 202 is adjusted to the desired angle, the limiting column 7 can be inserted into the corresponding limiting hole.

[0039] Referring to Figure 1 , the top of the processing box 1 is connected with the feeding hopper 8, and the feeding hopper 8 is in the shape of a funnel.

[0040] In the embodiment, the feeding hopper 8 is convenient for guiding the raw materials.

[0041] Referring to Figure 1 , the processing box 1 is connected with the flow guide seat 14, and the flow guide seat 14 is in the shape of an inverted trapezoid.

[0042] It should be noted that an electronic valve can be arranged at the bottom of the flow guide seat 14.

[0043] In specific implementation, the guide seat 14 can provide a guide effect for the material.

[0044] With reference to Figure 1 The filter plate 13 is detachably connected to the treatment box 1 and is used for secondary filtration of the sewage.

[0045] In specific implementation, the filter plate 13 can further filter the impurities.

[0046] Working principle: In order to adjust the angle of the stirring blade 202, two driving racks 203 slide in the stirring drum 201. Since the driving rack 203 is in mesh connection with the first transmission gear 204 on the connecting shaft of the stirring blade 202, when the driving rack 203 moves, the first transmission gear 204 will rotate, thereby driving the connecting shaft to rotate, and finally realizing the change of the angle of the stirring blade 202. When the material to be processed has different characteristics, for example, has a large viscosity, the moving direction and distance of the driving rack 203 can be controlled to adjust the stirring blade 202 to a more inclined angle, so that the thrust on the material during stirring can be increased, the stirring effect can be enhanced, and the material can be mixed more uniformly. For the material with a large density, the stirring blade 202 can be expanded to a larger shape through corresponding adjustment, so as to expand the stirring range, ensure that the material can be fully stirred at each position, improve the overall stirring efficiency and quality, and meet the strict requirements of polyimide composite engineering plastic preparation process on material mixing uniformity and fullness.

[0047] When adjusting the angle of the stirring blade 202, when one of the driving racks 203 is driven to move, for example, the driving rack 203 connected with the first connecting rack 301 at the top is driven to move. The movement of the first connecting rack 301 will drive the second transmission gear 302 engaged therewith to rotate, and since the second transmission gear 302 is also in mesh connection with the second connecting rack 303, the rotation of the second transmission gear 302 will make the second connecting rack 303 move in the opposite direction. The second connecting rack 303 is connected to the other driving rack 203 at the top, so that the reverse synchronous movement of the two driving racks 203 is realized.

[0048] The setting can make the two driving racks 203 work cooperatively and adjust the angle of the stirring blade 202 through the transmission of the second transmission gear 302 by acting on one of the driving racks 203 by a driving source. When facing different characteristics of polyimide composite engineering plastic preparation raw materials, the angle of the stirring blade 202 can be changed more efficiently to meet the needs.
