Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene wax production, in particular to a polyethylene wax discharging device. Background Art

[0002] Polyethylene wax is a chemical material that is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. After the polyethylene wax is pyrolyzed and melted at high temperature, it needs to be cooled by a cooling device to obtain a solid polyethylene wax for easy packaging and transportation.

[0003] The patent document with announcement number CN214537488U discloses a polyethylene wax discharge cooling device, which delivers cold water from the water inlet into the cooling tank so that the heat of the liquid polyethylene wax in the cooling pipe can be absorbed by the water in the cooling tank and discharged from the water outlet, thereby pre-cooling the liquid polyethylene wax flowing out of the reactor discharge port to ensure that the polyethylene wax falling onto the conveying device is completely solidified.

[0004] The above-mentioned discharge cooling device still has some technical deficiencies and shortcomings. Since the polyethylene wax in the cooling pipe is in a thick liquid or nearly semi-solid state, it is relatively stable when flowing in the pipe, making it difficult for the polyethylene wax in the center to be effectively pre-cooled, and the temperature is still high, making it difficult to avoid subsequent adhesion problems; and since the cold water in the cooling tank flows slowly, it is difficult for the water on the outer side of the tank body to blend with the water on the side of the pipe, which can easily lead to heat accumulation and rapid temperature rise, thereby affecting the subsequent cooling effect. For this reason, a polyethylene wax discharge device is now needed to solve the above-mentioned problems. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Figure 1-Figure 3 The schematic diagram of the whole structure of the polyethylene wax discharging device of the utility model is shown. Figure 1-Figure 3 A polyethylene wax discharging device of this embodiment includes a cooling tank 100, a cooling conveying cabin 200 is arranged in the center line of the cooling tank 100 and along its length direction, a spiral push rod 1 210 is arranged on one side of the inner cavity of the cooling conveying cabin 200, and a spiral push rod 220 parallel to the spiral push rod 1 210 is arranged on the other side of the inner cavity, a feed pipe 240 is arranged at one end of the top of the cooling conveying cabin 200, and a discharge pipe 230 is arranged at the other end of the cooling conveying cabin 200 away from the feed pipe 240, and the cooling conveying cabin 200 A driving box 250 is also provided at one end, which can drive the spiral push rod 1 210 and the spiral push rod 220 to rotate synchronously. A drain outlet 110 is provided at one end of the cooling trough 100 and a water inlet 120 is provided at the other end. A plurality of guide plates 300 are arranged on the inner side of the cooling trough 100 along its length direction and are staggered and covered on the outer side of the cooling and conveying cabin 200. A circulating conveying component 400 is also provided on the outer side of the cooling trough 100, which cooperates with the drain outlet 110 and the water inlet 120 and accelerates the circulation rate of cold water in the cooling trough 100.

[0025] The driving box 250 is provided with a first gear 251 fixed to the end of the spiral push rod 1 210, a second gear 252 fixed to the end of the spiral push rod 220, a main gear 253 meshed with the first gear 251 and the second gear 252 on both sides, and a motor 254 fixed to the driving box 250 and with the output shaft connected to the main gear 253. When in use, the started motor 254 can drive the first gear 251 and the second gear 252 to rotate synchronously through the main gear 253, so that the first gear 251 and the second gear 252 can drive the spiral push rod 1 210 and the spiral push rod 220 to rotate synchronously and in the same direction. The polyethylene wax melt in the cooling and conveying cabin 200 is linearly pushed and radially stirred by the spiral push rod 1 210 and the spiral push rod 220, so that the two melts are counteracted and blended during the advancement. In this way, the inner and outer layers of polyethylene wax are fully heat exchanged and evenly cooled, and the pre-cooling effect is significantly improved, ensuring that there will be no adhesion problems in the subsequent process.

[0026] The outer wall of the cooling and conveying cabin 200 is also coated with a thermal conductive coating 260; wherein, the inner cavity of the cooling and conveying cabin 200 has arc chambers corresponding to the spiral push rod 1 210 and the spiral push rod 2 220 on both sides, and the arc chambers can ensure that the melt in the cabin can be fully stirred. Through the setting of the thermal conductive coating 260, the cold temperature of the medium in the cooling trough 100 can be efficiently absorbed by the cooling and conveying cabin 200, thereby improving the pre-cooling effect of the melt flow medium in the cabin.

[0027] Furthermore, the top of the cooling tank 100 is also covered with a cover plate 130. The cover plate 130 can be set to seal the cooling tank 100, thereby reducing the dissipation of cold air as much as possible, thereby saving energy and reducing consumption.

It can be understood that the cold water source can be a condensing device, groundwater or a cold water pool, etc., as long as it can provide the temperature and circulating cooling required for precooling of the polyethylene wax; specifically, in actual use, the water pipe 410 is connected to the water inlet 120. Water pipe 2 430 can also determine whether to be equipped with liquid pump 420 according to actual needs. The cooling water in the cooling trough 100 can be circulated and guided by the cooperation of water pipe 1 410, water pipe 2 430 and liquid pump 420. At the same time, the staggered guide plates 300 can form the cooling trough 100 into an S-shaped narrow flow right-angle channel, so that the cold water can form a reversing collision and fusion in the rapid flow, which can effectively prevent the problem of heat accumulation in the cold water in the trough, and the pre-cooling and cooling effects are further improved.

[0029] Furthermore, the outer side of the cooling tank 100 is provided with a heat-insulating layer, which can further prevent the cold air in the cooling tank 100 from being lost and dissipated, and also avoid the interference of the external temperature on the temperature in the tank.

[0030] In summary, a polyethylene wax discharging device according to the present embodiment, when in use, continuously introduces the molten polyethylene wax into the cooling and conveying cabin 200 through the feed pipe 240, and at the same time, the driving mechanism in the driving box 250 drives the spiral push rod 1 210 and the spiral push rod 220 to rotate synchronously and in the same direction, and the polyethylene wax melt in the cooling and conveying cabin 200 is linearly pushed and radially stirred by the spiral push rod 1 210 and the spiral push rod 220, so that the two melts are counteracted and blended during the advancement, so that the inner and outer layers of the polyethylene wax are fully heat exchanged and evenly cooled, and the pre-cooling effect is significantly improved. At the same time, with the cooperation of the water pipe 1 410, the water pipe 2 430 and the liquid pump 420, the cooling water in the cooling tank 100 can be circulated and diverted, and the staggered guide plates 300 can form the cooling tank 100 into an S-shaped narrow flow right-angle channel, so that the cold water forms a reversing collision and blending in the rapid flow, which can effectively prevent the problem of heat accumulation in the cold water in the tank.
