Description

Technical Field

[0001] This utility model belongs to the technical field of cooling equipment for adhesive production, and more specifically, it relates to a cooling device for PVC pipe adhesive production. Background Technology

[0002] PVC pipe adhesive is an adhesive used to connect and fix PVC pipes and fittings. It works by dissolving the PVC surface, allowing two parts of the pipe or fitting to bond tightly and form a strong connection after adhesion. During adhesive production, high temperatures can continuously trigger side reactions. For example, epoxy resin is prone to excessive cross-linking above 120°C, leading to an abnormally high viscosity. Cooling to below 80°C slows down molecular chain movement and locks in the desired degree of polymerization. Adhesive cooling equipment is used to cool hot or liquid adhesives to an appropriate temperature.

[0003] Based on the above, the inventors have discovered the following problems: In the process of using existing cooling equipment for adhesive production, most of the equipment does not perform preliminary cooling treatment on the adhesive, which increases the cooling time of the equipment, the adhesive cools slowly, and thus reduces the cooling efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cooling device for the production of PVC pipe adhesives, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of this utility model of a cooling device for the production of PVC pipe adhesives are achieved by the following specific technical means:

[0006] A cooling device for producing PVC pipe adhesives includes a jacketed cooling tank. The top of the jacketed cooling tank has a cooling groove. An annular seat is mounted on the top of the jacketed cooling tank. A cover plate is mounted on the top of the annular seat. A pair of feed inlets are located on the top of the cover plate. A motor is mounted on the top of the cover plate. A rotating rod is rotatably mounted on the bottom of the cover plate. A stirring rod is mounted on the bottom of the rotating rod. Several blades are mounted on the bottom of the stirring rod. The output end of the motor is connected to the rotating rod. A preliminary cooling assembly is installed inside the annular seat.

[0007] Furthermore, the preliminary cooling assembly includes an annular frame, with a pair of limiting blocks installed on both sides of the annular frame, and a pair of limiting grooves provided at both ends of the inner side of the annular seat, with the pair of limiting blocks slidably connected to the pair of limiting grooves.

[0008] Furthermore, a pair of ventilation slots are provided on both sides of the ring frame, a partition plate one is installed on the inner side of the ring frame at the top of the ventilation slot, and a partition plate two is installed on the inner side of the ring frame at the bottom of the ventilation slot. Both the partition plate one and the partition plate two have several perforations on their surfaces.

[0009] Furthermore, the annular seat has several mounting slots on its periphery, and a fan is installed inside each of the mounting slots. The mounting slots are connected to the ventilation slots.

[0010] Furthermore, the annular seat is provided with a number of heat dissipation holes at equal intervals on its periphery.

[0011] Furthermore, the stirring rod and the rotating rod are detachably connected, and one end of the stirring rod passes through the first partition and the second partition and extends into the interior of the cooling tank.

[0012] Furthermore, the jacketed cooling vessel has an inlet on one side of its top end, an outlet on one side of its bottom end, a discharge port at its bottom end, and several support frames installed around its perimeter.

[0013] Furthermore, a controller is installed on one side of the jacketed cooling vessel, and the controller is electrically connected to the motor and the fan respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the coordinated use of the fan, partition one, partition two, ventilation slots, and drain holes, the adhesive enters from the inlet onto partition one, and then drips down through the drain holes on partition one to the surface of partition two. Due to the adhesive's viscosity, the fan blows air onto the adhesive as it falls onto partition two, accelerating heat dissipation. The heat is then dissipated through the heat dissipation holes, preventing heat accumulation in the annular seat. The adhesive then enters the cooling tank through the drain holes on partition two. This pretreatment reduces the adhesive's temperature and improves subsequent cooling efficiency.

[0016] By using the limit block and the limit groove together, the limit block and the limit groove are slidably connected. The ring frame can be removed by pulling it upward, so that the ring frame can be replaced or cleaned, which improves work efficiency. Attached Figure Description

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a cooling device for the production of PVC pipe adhesives, including a jacketed cooling tank 1. The top of the jacketed cooling tank 1 is provided with a cooling groove 7. An annular seat 2 is installed at the top of the jacketed cooling tank 1. A cover plate 3 is installed at the top of the annular seat 2. A pair of feed inlets 5 are provided at the top of the cover plate 3. A motor 4 is installed at the top of the cover plate 3. A rotating rod 8 is rotatably installed at the bottom of the cover plate 3. A stirring rod 9 is installed at the bottom of the rotating rod 8. Several blades 10 are installed at the bottom of the stirring rod 9. The output end of the motor 4 is connected to the rotating rod 8 for transmission. A preliminary cooling component is installed inside the annular seat 2. The motor 4 drives the rotating rod 8 to rotate, which in turn drives the stirring rod 9 to rotate. The stirring rod 9 drives the blades 10 to rotate, stirring the adhesive and cooling the heat of the adhesive evenly.

[0029] The preliminary cooling assembly includes a ring frame 11, with a pair of limiting blocks 12 installed on both sides of the ring frame 11. A pair of limiting grooves 13 are provided at both ends of the inner side of the ring seat 2. The pair of limiting blocks 12 and the pair of limiting grooves 13 are slidably connected. Through the cooperation between the limiting blocks 12 and the limiting grooves 13, the limiting blocks 12 and the limiting grooves 13 are slidably connected. The ring frame 11 can be removed by pulling it upward, so that the ring frame 11 can be replaced or cleaned, which improves work efficiency.

[0030] The ring frame 11 has a pair of ventilation slots 18 on both sides. A partition 15 is installed on the inner side of the ring frame 11 at the top of the ventilation slot 18. A partition 2 16 is installed on the inner side of the ring frame 11 at the bottom of the ventilation slot 18. Both the partition 15 and the partition 2 16 have several holes 17 on their surfaces.

[0031] The annular seat 2 has several mounting grooves 6 around its periphery. A fan 14 is installed inside each of the mounting grooves 6. The mounting grooves 6 are connected to the ventilation grooves 18. Through the cooperation of the fan 14, partition 15, partition 2 16, ventilation grooves 18 and drain holes 17, the adhesive enters from the feed inlet 5 onto partition 15, and then leaks down through the drain holes 17 on partition 15 to the surface of partition 2 16. Since the adhesive has a certain stickiness, the fan 14 blows air onto the adhesive during the process of falling onto partition 2 16, accelerating the heat evaporation. The adhesive then enters the cooling tank 7 through the drain holes 17 on partition 2 16. After pretreatment, the temperature of the adhesive can be reduced, and the subsequent cooling efficiency can be improved.

[0032] The annular seat 2 is provided with a plurality of heat dissipation holes 19 at equal intervals on its periphery. Heat can be discharged through the heat dissipation holes 19 to prevent heat from accumulating in the annular seat 2.

[0033] The stirring rod 9 and the rotating rod 8 are detachably connected. One end of the stirring rod 9 passes through the first partition 15 and the second partition 16 and extends into the interior of the cooling tank 7. The detachable connection between the stirring rod 9 and the rotating rod 8 facilitates the removal of the ring frame 11.

[0034] The jacketed cooling vessel 1 has an inlet 21 on one side of its top end, an outlet 22 on one side of its bottom end, and a discharge port 23 at its bottom end. Several support frames 24 are installed around the jacketed cooling vessel 1. Through the cooperation of the inlet 21, outlet 22, and discharge port 23, cooling water enters from the inlet 21, and cooling water circulates through the jacket of the jacketed cooling vessel 1 and is discharged from the outlet 22, carrying away heat and cooling the adhesive. The adhesive is discharged from the discharge port 23 and enters the next process.

[0035] The jacketed cooling vessel 1 is equipped with a controller 20 on one side. The controller 20 is electrically connected to the motor 4 and the fan 14 respectively. The controller 20 can control the start of the fan 14 and control the speed of the fan 14.

[0036] The specific usage and function of this embodiment are as follows:

[0037] First, check the integrity of the device. Only after confirming it is intact can it be used. During use, the adhesive first enters the first partition 15 through the inlet 5, and then flows down through the drain hole 17 on the first partition 15 to the surface of the second partition 16. Due to the adhesive's viscosity, as it falls onto the second partition 16, the controller 20 activates the fan 14. The fan 14 blows air onto the adhesive, accelerating heat dissipation. The heat is then discharged through the heat dissipation hole 19, preventing heat accumulation in the annular seat 2. The adhesive then enters the cooling tank 7 through the drain hole 17 on the second partition 16. This pretreatment reduces the adhesive's temperature and improves subsequent cooling. The efficiency is improved by using cooling water to enter through inlet 21, circulating cooling water through the jacket of the jacketed cooling vessel 1, and driving the rotating rod 8 to rotate, which in turn drives the stirring rod 9 to rotate. The stirring rod 9 drives the blades 10 to rotate, stirring the adhesive. Cooling water is discharged from outlet 22, carrying away heat and cooling the adhesive. The adhesive is discharged from discharge port 23 and enters the next process. After cooling, the limiting block 12 slides with the limiting groove 13, and the ring frame 11 can be removed by pulling it upward. The ring frame 11 can then be replaced or cleaned, improving work efficiency. This device has a novel overall design and simple structure, and is therefore worthy of widespread promotion and use.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
