Description

Technical Field

[0001] The utility model relates to the field of polyester resin production, in particular to a packing tower for polyester resin synthesis. Background Art

[0002] Polyester resin is a general term for polymer compounds formed by the condensation of diols or dibasic acids or polyols and polyacids. Polyester resins are divided into saturated polyester resins and unsaturated polyester resins. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments, fillers, initiators and other additives. The adhesive has low viscosity, is easy to wet, and has good processability. The cured adhesive layer has high hardness, good transparency, high brightness, can be quickly cured under pressure at room temperature, has good heat resistance, and excellent electrical properties. During the synthesis reaction of polyester resin, a packing tower is required to perform a gas-liquid exchange reaction on the polyester resin. Existing packing towers usually use a fixed spraying method to spray the liquid polyester resin on the upper end of the packing during use. However, the fixed spraying of the liquid polyester resin will inevitably produce some spraying dead angles, which makes it impossible for the liquid polyester resin to evenly cover the upper end of the packing, affecting the processing efficiency of the packing tower for the polyester resin.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-4 The utility model provides an embodiment: a packed tower for polyester resin synthesis, comprising a packed tower body 1:

[0026] A liquid polyester resin filling pipe 9 is arranged at the upper end of the packing tower body 1. The packing tower body 1 is rotatably connected to the liquid polyester resin filling pipe 9 through a bearing. A hollow square shaft 15 is welded to the lower end of the liquid polyester resin filling pipe 9. The lower end of the hollow square shaft 15 is rotatably connected to an eccentric liquid outlet bracket 17 through a connecting shaft. The eccentric liquid outlet bracket 17 is arranged. By utilizing its offset center of gravity, the centrifugal force on the eccentric liquid outlet bracket 17 when the eccentric liquid outlet bracket 17 rotates at a high speed is greater than the effect of gravity. The eccentric liquid outlet bracket 17 will gradually become parallel to the horizontal plane, so that the liquid polyester resin sprayed from the flexible nozzle 18 at the lower end of the eccentric liquid outlet bracket 17 can be evenly spread on the upper end of the packing body 3. When 17 rotates at a low speed, the eccentric liquid outlet bracket 17 has a certain angle with the horizontal plane under the effect of centrifugal force being less than gravity, so that the liquid outlet angle of the flexible nozzle 18 can be adjusted. In this way, the change of the rotation speed of the eccentric liquid outlet bracket 17 can adjust the liquid outlet angle of the flexible nozzle 18, so that the liquid polyester resin sprayed by the flexible nozzle 18 can be evenly sprayed on the upper end of the filler body 3, thereby ensuring the processing efficiency of the device for the polyester resin and preventing the occurrence of spraying dead angles. A plurality of flexible nozzles 18 are arranged at the lower end of the eccentric liquid outlet bracket 17, and connecting hoses 16 are installed on both sides of the upper end of the eccentric liquid outlet bracket 17, and the connecting hoses 16 are fixedly connected to the eccentric liquid outlet bracket 17 and the hollow square shaft 15;

[0027] The heat source blocking bracket 7 is arranged on the outside of the eccentric liquid outlet bracket 17. The installation of the heat source blocking bracket 7 can prevent the sprayed polyester resin from being sprayed onto the inner wall of the packing tower body 1. Since the packing tower body 1 is close to the outside of the device, the temperature is slightly lower, which prevents the polyester resin from solidifying when it is cold, thereby enhancing the practicability of the device. The heat source blocking bracket 7 is welded to the packing tower body 1. A heating pipe 8 is fixedly installed on the outside of the eccentric liquid outlet bracket 17. The installation of the heating pipe 8 can heat the liquid polyester resin to ensure the fluidity of the liquid polyester resin, prevent the liquid polyester resin from solidifying when it is cold, and prevent the solidified liquid polyester resin from clogging the device. The outside of the liquid polyester resin filling pipeline 9 is provided with A driven gear 10 is fixedly connected to the liquid polyester resin filling pipe 9. A mounting bracket 11 is fixedly installed on the front end of the upper end surface of the filling tower body 1. A driving gear shaft 12 is installed at the lower end of the mounting bracket 11. The driving gear shaft 12 is meshingly connected to the driven gear 10. A flat anti-blocking scraper 6 is installed on one side of the hollow square shaft 15. The flat anti-blocking scraper 6 is welded to the hollow square shaft 15. The flat anti-blocking scraper 6 can be installed to rotate synchronously with the hollow square shaft 15 to scrape the liquid polyester resin, so that the liquid polyester resin can be flattened on the upper end of the filling body 3, thereby enhancing the use effect of the device. The flat anti-blocking scraper 6 slides on the inner side of the heat source blocking bracket 7.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A packing card platform 2 is arranged on the inner side of the packing tower body 1. The packing card platform 2 and the packing tower body 1 are arranged as an integrally formed structure. The packing card platform 2 can quickly clamp the packing body 3 to prevent the packing body 3 from shaking. The packing body 3 is arranged on the outside of the packing card platform 2. The packing body 3 is connected to the packing card platform 2 through a card groove. A pressure relief pipe 4 is installed inside the packing body 3. The pressure relief pipe 4 is fixedly connected to the packing body 3. An air outlet valve 5 is arranged on the upper end of the pressure relief pipe 4. The air outlet valve 5 can ensure the circulation of gas inside the device to avoid the packing body 3 inside the device from moving up and down. The air pressure difference at both ends is too large, which enhances the practicability of the device. A gas inlet pipe 14 is arranged on the side of the upper end face of the packing tower body 1 away from the flat anti-blocking scraper 6. The gas inlet pipe 14 is welded to the packing tower body 1. A discharge pipe 19 is installed at the lower end of the packing tower body 1. The discharge pipe 19 is welded to the packing tower body 1. A control box 20 is installed on the front end face of the packing tower body 1. The control box 20 is fixedly connected to the packing tower body 1. A driving motor 13 is fixedly installed on the upper end face of the mounting bracket 11. The driving motor 13 is connected to the driving gear shaft 12 through a coupling.

[0029] The specific use process of the utility model is as follows: the staff adds the liquid polyester resin into the hollow square shaft 15 through the liquid polyester resin filling pipe 9, and then the liquid polyester resin enters the eccentric liquid outlet bracket 17 through the connecting hose 16 under the action of gravity. At the same time, the staff adds gas into the device through the gas introduction pipe 14. Next, the driving motor 13 drives the liquid polyester resin filling pipe 9 to rotate through the driving gear shaft 12 and the driven gear 10. The liquid polyester resin filling pipe 9 drives the hollow square shaft 15 and the eccentric liquid outlet bracket 17 to rotate. At first, the eccentric liquid outlet bracket The rotation speed of 17 is low, and the centrifugal force on the eccentric liquid outlet bracket 17 is smaller than the gravity, so the eccentric liquid outlet bracket 17 presents a certain angle with the horizontal plane, so that the liquid polyester resin is discharged at a certain angle by adjusting the flexible nozzle 18, so that the liquid polyester resin falls on the upper end of the filler body 3. As the rotation speed of the eccentric liquid outlet bracket 17 gradually increases, the centrifugal force on the eccentric liquid outlet bracket 17 gradually equals or exceeds the gravity. At this time, the eccentric liquid outlet bracket 17 will gradually turn over until it is parallel to the horizontal plane. In this process, the liquid outlet angle of the flexible nozzle 18 will change, so that the sprayed liquid polyester The resin is evenly spread on the upper end of the packing body 3, and the flat anti-blocking scraper 6 is used to flatten the liquid polyester resin to ensure that the liquid polyester resin is evenly spread on the upper end of the packing body 3. In this way, the driving motor 13 controls the rotation speed of the eccentric liquid outlet bracket 17 from small to large, and then from large to small, for a reciprocating cycle. Next, the liquid polyester resin evenly enters the interior of the packing body 3 to fully exchange gas and liquid with the gas. Finally, the liquid polyester resin is discharged from the device through the discharge pipe 19. The device is equipped with a heat source blocking bracket 7 to prevent the sprayed polyester resin from spraying onto the inner wall of the packing tower body 1. The body 1 is close to the outside of the device, so the temperature is slightly lower, which prevents the polyester resin from solidifying when it is cold and enhances the practicability of the device. The heating tube 8 can be installed to heat the liquid polyester resin to ensure the fluidity of the liquid polyester resin, prevent the liquid polyester resin from solidifying when it is cold, and prevent the solidified liquid polyester resin from clogging the device. The flat anti-blocking scraper 6 can rotate synchronously with the hollow square shaft 15 to scrape the liquid polyester resin, so that the liquid polyester resin can be flatly spread on the upper end of the filler body 3, thereby enhancing the use effect of the device. The filler clamping table 2 can quickly clamp the filler body 3 to prevent the filler body 3 from shaking.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
