Abstract
Description
Technical Field
[0001] This utility model relates to the field of polypropylene production technology, specifically a cooling device for polypropylene production. Background Technology
[0002] Cooling devices for polypropylene production refer to devices used in the polypropylene production process specifically designed to transfer heat from polypropylene materials in the production state. This ensures the quality and performance of polypropylene products and facilitates subsequent storage, transportation, and further processing. Cooling devices are typically required to cool polypropylene materials.
[0003] A search revealed Chinese patent application CN202123166599.0, which discloses a cooling device for polypropylene production. The device includes an extrusion box for extruding polypropylene strips, a spray ring, and a support plate. A horizontal pipe is connected to the top branch pipe of the spray ring. In this invention, the spray ring prevents the bottom of the polypropylene strip from being insufficiently cooled. The atomizing nozzle prevents pressure from causing deformation of the spray ring. When cooling the polypropylene strip, a rotating shaft, pulley, and synchronous belt transport the strip. Water from the water tank is pumped out via the rotating shaft and flows sequentially along the main pipe, horizontal pipe, and branch pipe into the spray ring. Finally, the water is sprayed onto the surface of the polypropylene strip through the atomizing nozzle, achieving comprehensive cooling. An inclined plate and a drain outlet allow cooling water to be sprayed from the atomizing nozzle, cooling the polypropylene strip, and then falling to the top of the inclined plate. The water then flows down the inclined plate and into the water tank through the drain outlet, thus collecting the cooling water for reuse.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Although the existing technologies use water cooling to cool the extrusion molding equipment, during the cooling process, the outer surface of the molded material may absorb some water stains. During subsequent material movement, these water stains will spill onto the ground, making the ground slippery and increasing safety hazards. Furthermore, subsequent manual secondary processing of the workpiece is required, increasing labor costs. Therefore, it is necessary to design a practical cooling device for polypropylene production that can remove water stains. Utility Model Content

Detailed Implementation
[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] Please see Figure 1-5The present invention provides a technical solution: a cooling device for polypropylene production, including a cooling box 1, a water pump 2 fixedly connected to one side of the inner wall of the cooling box 1, an L-shaped pipe 3 located on the upper side of the cooling box 1 fixedly connected to the output end of the water pump 2, a diversion pipe 4 provided at one end of the L-shaped pipe 3, and a plurality of cooling rings 5 provided at the lower end of the diversion pipe 4.
[0025] An external frame 6 is fixedly connected to one side of the cooling box 1. Two pressure plates 7 are fixedly connected to the upper side of the external frame 6. A drive block 8 is fixedly connected to one side of each of the two pressure plates 7. A tilting cylinder 9 is fixedly connected to one side of each of the drive blocks 8. A cleaning component 10 is provided at the output end of each of the tilting cylinders 9. A drying mechanism 11 is provided on one side of one of the two pressure plates 7.
[0026] Please see Figure 2 and Figure 3 The cleaning assembly 10 includes an empty slot block 101 fixedly connected to the output ends of two tilting cylinders 9, a drive motor 102 fixedly connected to the upper side of the empty slot block 101, a drive gear 103 fixedly connected to the output end of the drive motor 102, toothed plates 104 slidingly engaged with the drive gear 103 on both sides of the inner wall of the empty slot block 101, a mounting plate 105 fixedly connected to the opposite side of the two toothed plates 104, and a cleaning sponge 106 fixedly connected to the opposite side of the two mounting plates 105. The drive motor 102 drives the drive gear 103 to rotate, pushing the two toothed plates 104 to move, so that the cleaning sponge 106 on the mounting plate 105 cleans the workpiece. The cleaning sponge 106 is brought into contact with water to absorb surface water stains. After cleaning, the cleaning sponge 106 is flipped by the flipping cylinder 9, so that the cleaning sponge 106 on the other side is switched with the cleaning sponge 106 on the other side. When cleaning is performed next time, the cleaning sponge 106 with water stains will be squeezed by the corresponding pressure plate 7 to squeeze out the water stains. When the cleaning sponge 106 absorbs water, the water will fill the pores inside the cleaning sponge 106. The squeezing operation of the sponge only squeezes out the water that was originally stored in the pores from the sponge. When the cleaning sponge 106 is placed near a water source or in direct contact with water again, the water can re-enter the interior through the pores of the sponge to absorb water again.
[0027] Please see Figure 4 The drying mechanism 11 includes an air pump 111 fixedly connected to one side of one of the two pressure plates 7, a hollow ring 112 fixedly connected to the output end of the air pump 111 and extending to the center of the two pressure plates 7, and multiple air outlets 113 opened on the inner wall of the hollow ring 112. High-pressure gas is injected into the hollow ring 112 by the air pump 111. The hollow ring 112 is an annular body with a hollow interior. The output end of the air pump 111 extends into the hollow interior. The air pump 111 injects gas into the hollow interior of the hollow ring 112 and then discharges it from the multiple air outlets 113.
[0028] Please see Figure 3 Guide openings 12 are provided on both sides of the two empty slot blocks 101. Guide blocks 13 that are fixedly connected to the toothed plate 104 are slidably fitted on the inner walls of the two guide openings 12. When the toothed plate 104 moves, its guide blocks 13 will slide inside the guide openings 12, thereby limiting the corresponding toothed plate 104.
[0029] Please see Figure 1 A semiconductor refrigerator 14 is fixedly connected to one side of the cooling box 1. The semiconductor refrigerator 14 achieves its cooling function based on the Peltier effect. When direct current passes through a couple composed of two different semiconductor materials, heat absorption and heat release phenomena will occur at the two ends of the couple, respectively. One end will decrease in temperature and become the cold end, while the other end will increase in temperature and become the hot end. This is a prior art technology. A temperature-conducting plate 15 extending to the inner wall of the cooling box 1 is fixedly connected to one side of the semiconductor refrigerator 14. The temperature-conducting plate 15 is fixed to the cold end face. The semiconductor refrigerator 14 can cool the water source inside the cooling box 1 and improve the cooling effect.
[0030] Please see Figure 4 and Figure 5 An air inlet frame 16 is fixedly connected to one side of the two pressure plates 7. The input end of the air pump 111 extends into the interior of the air inlet frame 16. A heating tube 17 is provided on one side of the inner wall of the air inlet frame 16. The air inlet frame 16 can be used to guide the air intake direction of the air pump 111. The heating tube 17 can heat the flowing air, so that the air blown out of the air outlet 113 is heated and the drying effect is improved.
[0031] Please see Figure 5 A dustproof net 18 is provided on one side of the air intake frame 16. The dustproof net 18 is fixed to the air intake frame 16 by screws. The dustproof net 18 can facilitate dust prevention at the air intake end of the air intake frame 16, thereby improving the quality of the air ejected by the drive gear 103 and avoiding material contamination.
[0032] The implementation principle of this application is as follows: When using this device, first move the cooling box 1 to the side of the corresponding extrusion equipment, extrude the equipment from inside the cooling ring 5, inject clean water into the cooling box 1, then use the water pump 2 to draw the clean water, inject it into the inside of the diversion pipe 4 through the L-shaped pipe 3, and then inject it into the inside of the cooling ring 5 through the diversion pipe 4. The water is then sprayed out through the annular atomizing nozzle inside the cooling ring 5 to cool the material.
[0033] After cooling, the cooled material will flow between the two adjacent cleaning sponges 106. Then, the drive motor 102 will be started to drive the drive gear 103 to rotate. The drive gear 103 will drive the two toothed plates 104 to move, so that one side of the cleaning sponge 106 will squeeze the material to wrap it. When the material moves, the water on the surface of the material will be wiped through the gaps of the cleaning sponge 106, improving the cleanliness after cooling and reducing the environmental pollution caused by residual water stains after cooling. After processing a workpiece, the empty slot block 101 can be rotated 180 degrees by driving the flipping cylinder 9 to change the position of the cleaning sponge 106. When used again, the cleaning sponge 106 that originally absorbed water will squeeze between the pressure plate 7, squeezing out the water in the gaps and flowing into the outer frame 6 to ensure continuous use.
[0034] After the water stains are wiped off, the workpiece moves from inside the empty groove ring 112. By starting the air pump 111, high-pressure air is injected into the empty groove ring 112 through its output end. The air flows out from the air outlet 113, which makes the airflow flow quickly to the surface of the workpiece to accelerate the drying effect, avoid the adverse effects of moisture residue on material quality and equipment operation, and further ensure product quality.
