Description

Technical Field

[0001] This utility model belongs to the field of granulator material conveying technology, specifically relating to a granulator conveying mechanism. Background Technology

[0002] A granulator is a device that crushes and mixes materials or mixtures into granules. Existing granulators discharge the granules directly. Because the raw materials need to be melted during the granulation process and then discharged through extrusion and cutting, and the granules are at a high temperature during the discharge process, it is not suitable to collect them directly.

[0003] CN221906956U discloses a discharge mechanism for granulation processing in a granulator, comprising a granulator body, a base plate connected to the bottom of the granulator body, a support box connected to the top of the base plate, a support plate connected to the top of the support box, and two fixing plates on the top of the support plate. This invention uses a water pump to draw cooling liquid from the support box and deliver it to a delivery pipe. The liquid then enters a telescopic pipe, a cavity, and multiple horizontal bars. The cooling liquid in the horizontal bars enters multiple vertical bars, another cavity, and another telescopic pipe. Finally, it enters a heat exchanger through a discharge pipe and is returned to the support box. This process is repeated to effectively cool the discharged granules rapidly, allowing for centralized collection of the granules.

[0004] Since the high-temperature granules discharged from the granulator are not shaped, especially when the granulator is granulating plastic materials, the discharged plastic granules need to be cooled and shaped. Although the discharge mechanism provided by the above patent can cool the high-temperature granules discharged from the granulator, the contact range between the cooling components and the granules is limited, so the cooling effect on the granules is not good, which makes the granules after vibrating screening potentially deformable. At the same time, although the discharge mechanism provided by the above patent can screen the granules, there is still room for improvement in the screening effect.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a granulator conveying mechanism that can solve the problems of poor cooling effect of the cooling component on high-temperature particles and incomplete screening of impurities in the particles by the screening component.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A granulator conveying mechanism, comprising:

[0009] The conveying mechanism includes a first cooling chamber shell and a second cooling chamber shell, which are integrally formed and connected together. The first and second cooling chamber shells are used to convey the high-temperature granules exiting the granulator; therefore, the inlet of the first cooling chamber shell is connected to the outlet of the granulator. Multiple first atomizing nozzles are installed through the top wall of the first cooling chamber shell, spraying cooling water onto the high-temperature granules conveyed inside, achieving initial cooling of the granules. Multiple second atomizing nozzles are installed through the top wall of the second cooling chamber shell, spraying cooling water onto the granules conveyed inside, achieving further cooling of the granules.

[0010] The screening and washing assembly includes a housing. The outlet of the second cooling chamber housing is fixedly connected to the inlet of the housing. Particles cooled in the first and second cooling chambers are conveyed into the housing for screening and washing. A screening plate is fixedly connected inside the housing. The screening plate has multiple sieve holes arranged in a ring. Particles entering the housing are screened through the sieve holes and fall below the screening plate. Multiple first magnetic rings are fixedly connected between the sieve holes on the bottom wall of the screening plate. As the particles flow downwards after being screened, they pass through the first magnetic rings, which adsorb any metal impurities contained in the particles, thus separating them. A filter screen is installed inside the housing. Particles screened by the screening plate fall onto the filter screen for washing. Small-diameter impurities during washing fall through the filter screen to the bottom of the housing.

[0011] In one or more embodiments of this utility model, the bottom wall panels of both the first cooling chamber shell and the second cooling chamber shell are inclined downwards from the feed inlet to the discharge outlet, so that the high-temperature particles exiting the granulator can roll within the first and second cooling chamber shells. The inclination angle of the bottom wall panel of the first cooling chamber shell is smaller than that of the bottom wall panel of the second cooling chamber shell, ensuring that the high-temperature particles roll at a slower speed within the first cooling chamber shell than within the second cooling chamber shell, thus preventing deformation of the high-temperature particles while rolling within the first cooling chamber shell.

[0012] In one or more embodiments of this utility model, each of the plurality of first atomizing nozzles and the plurality of second atomizing nozzles has an infusion branch pipe installed at its outer end. The infusion branch pipe is used to supply cooling water to the first atomizing nozzles and the second atomizing nozzles. An infusion tube is installed at the upper end of the infusion branch pipe, and the infusion tube is used to supply cooling water to the infusion branch pipe.

[0013] In one or more embodiments of this utility model, an outlet pipe is installed at the end of the infusion tube away from the infusion branch pipe, and the outlet pipe is used to supply cooling water to the infusion tube. A water pump is installed at the end of the outlet pipe away from the infusion tube, and the water pump is used to pressurize and transport the cooling water. An inlet pipe is installed on the inlet of the water pump, and the inlet pipe is used to supply water to the water pump.

[0014] In one or more embodiments of this utility model, a second magnetic ring is fixedly connected to the bottom of the first magnetic ring, and the two ends of the second magnetic ring are respectively disposed on both sides of the first magnetic ring. The second magnetic ring further processes the metal impurities in the falling particles.

[0015] In one or more embodiments of this utility model, a stirring shaft is rotatably connected between the top wall panel and the bottom wall panel of the housing, and multiple sets of stirring impellers are fixedly connected to the side wall of the stirring shaft, so that the stirring shaft can drive the multiple sets of stirring impellers to rotate.

[0016] In one or more embodiments of this utility model, multiple sets of stirring impellers are respectively arranged above the bottom wall plate of the housing, the filter screen, and the sieve plate, and a motor is installed at the upper end of the stirring shaft. The stirring impellers on the bottom wall plate of the housing are used to stir the solid impurities after they have passed through the filter screen, preventing them from settling at the bottom of the housing and making them difficult to clean. The stirring impellers on the filter screen are used to stir the particles after they have been sieved by the sieve plate, ensuring that the particles are cleaned. The stirring impellers on the sieve plate are used to stir the particles on the sieve plate, improving the sieve plate's particle sieving effect.

[0017] In one or more embodiments of this utility model, a first discharge port, a second discharge port, and a drain port are sequentially arranged on the side wall of the housing from top to bottom. A sealing layer is provided between the first discharge port, the second discharge port, and the drain port and the housing. The sealing layer ensures that the connection of the housing will not leak water after the first discharge port, the second discharge port, and the drain port are closed.

[0018] In one or more embodiments of this utility model, the bottom of the first discharge port is flush with the upper surface of the screening plate, the bottom of the second discharge port is flush with the upper surface of the filter screen, and the bottom of the drain port is flush with the upper surface of the bottom wall panel of the housing. Impurities and particles intercepted by the screening plate are discharged through the first discharge port, particles washed on the filter screen are discharged through the second discharge port, and impurities and waste liquid at the bottom of the housing are discharged through the drain port.

[0019] In one or more embodiments of this utility model, the side wall of the housing is provided with a liquid outlet above the filter screen, and the end of the liquid inlet pipe away from the water pump is installed on the liquid outlet. The cleaning liquid above the filter screen is transported to the water pump through the liquid outlet so that it can be pressurized by the water pump and then transported to the first atomizing nozzle and the second atomizing nozzle.

[0020] Compared with the prior art, this utility model sets up multiple cooling chambers in the conveying structure to achieve step-by-step cooling of high-temperature particles, which improves the cooling effect of particles while completing the shaping of particles, so that cooling does not affect the shaping of particles; and sets up a screening and washing component to screen and wash the particles after cooling, ensuring that the screening of particles does not affect the shaping of particles and improving the screening effect of particles.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-5 As shown, a granulator conveying mechanism in one embodiment of the present invention includes a conveying mechanism 1 and a screening and washing assembly 2.

[0031] like Figures 1-5 As shown, the conveying mechanism 1 includes a first cooling chamber shell 11 and a second cooling chamber shell 12, which are integrally formed and connected together. The first and second cooling chamber shells 11 and 12 are used to convey the high-temperature particles exiting the granulator. Therefore, the inlet of the first cooling chamber shell 11 is connected to the outlet of the granulator. Multiple first atomizing nozzles 13 are installed through the top wall of the first cooling chamber shell 11, spraying cooling water onto the high-temperature particles conveyed inside the first cooling chamber shell 11 to achieve initial cooling. Multiple second atomizing nozzles 14 are installed through the top wall of the second cooling chamber shell 12, spraying cooling water onto the particles conveyed inside the second cooling chamber shell 12 to achieve further cooling.

[0032] Preferably, in order to achieve the goal of shaping high-temperature particles through cooling while ensuring that the internal mechanical structure of the particles does not change during cooling, a stepped cooling process is used for the high-temperature particles in the first cooling chamber shell 11 and the second cooling chamber shell 12. Multiple first atomizing nozzles 13 installed in the first cooling chamber shell 11 use small-diameter nozzles, resulting in a smaller volume of cooling water sprayed from the first atomizing nozzles 13, thus controlling the cooling of the high-temperature particles. Multiple second atomizing nozzles 14 installed in the second cooling chamber shell 12 use larger-diameter nozzles, resulting in a larger volume of cooling water sprayed from the second atomizing nozzles 14, improving the cooling effect of the cooling water on the particles, and achieving the goal of cooling and shaping the particles. The multiple first atomizing nozzles 13 and multiple second atomizing nozzles 14 ensure that the sprayed cooling water covers both the first cooling chamber shell 11 and the second cooling chamber shell 12, thereby ensuring that all particles flowing within the first cooling chamber shell 11 and the second cooling chamber shell 12 are cooled.

[0033] like Figure 1 and Figure 5 As shown, the bottom wall panels of both the first cooling chamber shell 11 and the second cooling chamber shell 12 are inclined downwards from the feed inlet to the discharge outlet, allowing the high-temperature granules exiting the granulator to roll within the first cooling chamber shell 11 and the second cooling chamber shell 12. The inclination angle of the bottom wall panel of the first cooling chamber shell 11 is smaller than that of the bottom wall panel of the second cooling chamber shell 12, ensuring that the high-temperature granules roll at a slower speed within the first cooling chamber shell 11 than within the second cooling chamber shell 12, thus preventing deformation of the high-temperature granules while rolling within the first cooling chamber shell 11.

[0034] like Figure 2 and Figure 3 As shown, each of the multiple first atomizing nozzles 13 and multiple second atomizing nozzles 14 has an infusion branch pipe 15 installed at one end on the outer side. The infusion branch pipe 15 is used to supply cooling water to the first atomizing nozzles 13 and the second atomizing nozzles 14. An infusion pipe 16 is installed at the upper end of the infusion branch pipe 15, and the infusion pipe 16 is used to supply cooling water to the infusion branch pipe 15.

[0035] like Figure 1 and Figure 2 As shown, an outlet pipe 17 is installed at the end of the infusion tube 16 away from the infusion branch pipe 15. The outlet pipe 17 is used to supply cooling water to the infusion tube 16. A water pump 18 is installed at the end of the outlet pipe 17 away from the infusion tube 16. The water pump 18 is used to pressurize and transport the cooling water. An inlet pipe 19 is installed on the inlet of the water pump 18. The inlet pipe 19 is used to supply water to the water pump 18.

[0036] like Figures 1-5As shown, the screening and washing assembly 2 includes a housing 21. The outlet of the second cooling chamber housing 12 is fixedly connected to the inlet of the housing 21. Particles cooled in the first cooling chamber housing 11 and the second cooling chamber housing 12 are transported into the housing 21 for screening and washing. A screening plate 22 is fixedly connected inside the housing 21. Multiple screen holes 23 are formed in a ring on the screening plate 22. Particles entering the housing 21 are screened through the screen holes 23 on the screening plate 22 and fall below the screening plate 22. Multiple first magnetic rings 24 are fixedly connected between the multiple screen holes 23 on the bottom wall of the screening plate 22. When the particles screened through the screen holes 23 flow downward, they pass through the first magnetic rings 24. The first magnetic rings 24 can adsorb the metal impurities contained in the particles to achieve separation of metal impurities from the particles. A filter screen 26 is installed inside the housing 21. The particles screened by the sieve plate 22 will fall onto the filter screen 26 and be cleaned on the filter screen 26. Small particle impurities during the cleaning process will fall to the bottom of the housing 21 through the filter screen 26.

[0037] like Figures 3-5 As shown, a second magnetic ring 25 is fixedly connected to the bottom of the first magnetic ring 24. The two ends of the second magnetic ring 25 are respectively set on both sides of the first magnetic ring 24. The second magnetic ring 25 further processes the metal impurities in the falling particles.

[0038] like Figures 3-5 As shown, a stirring shaft 27 is rotatably connected between the top wall plate and the bottom wall plate of the housing 21. Multiple sets of stirring impellers 28 are fixedly connected to the side wall of the stirring shaft 27, and the stirring shaft 27 can drive the multiple sets of stirring impellers 28 to rotate.

[0039] like Figures 3-5 As shown, multiple sets of stirring impellers 28 are respectively arranged above the bottom wall plate of the housing 21, the filter screen 26, and the sieve plate 22. A motor 29 is installed at the upper end of the stirring shaft 27. The stirring impellers 28 on the bottom wall plate of the housing 21 are used to stir the solid impurities after they have passed through the filter screen 26, preventing them from settling at the bottom of the housing 21 and making them difficult to clean. The stirring impellers 28 on the filter screen 26 are used to stir the particles after they have been sieved by the sieve plate 22, ensuring that the particles are cleaned. The stirring impellers 28 on the sieve plate 22 are used to stir the particles on the sieve plate 22, improving the sieving effect of the sieve plate 22.

[0040] like Figures 3-5As shown, a first discharge port 210, a second discharge port 211, and a drain port 212 are arranged sequentially from top to bottom on the side wall of the housing 21. A sealing layer is provided between the first discharge port 210, the second discharge port 211, and the drain port 212 and the housing 21. The sealing layer ensures that the connection of the housing 21 will not leak water after the first discharge port 210, the second discharge port 211, and the drain port 212 are closed.

[0041] like Figures 3-5 As shown, the bottom of the first discharge port 210 is flush with the upper surface of the screening plate 22, the bottom of the second discharge port 211 is flush with the upper surface of the filter screen 26, and the bottom of the drain port 212 is flush with the upper surface of the bottom wall plate of the shell 21. Impurities and particles intercepted by the screening plate 22 are discharged through the first discharge port 210, particles washed on the filter screen 26 are discharged through the second discharge port 211, and impurities and waste liquid at the bottom of the shell 21 are discharged through the drain port 212.

[0042] like Figures 3-5 As shown, the side wall of the housing 21 has a liquid outlet 213 located above the filter screen 26. The end of the inlet pipe 19 away from the water pump 18 is installed on the liquid outlet 213. The cleaning liquid above the filter screen 26 is transported to the water pump 18 through the liquid outlet 213, so that it can be pressurized by the water pump 18 and then transported to the first atomizing nozzle 13 and the second atomizing nozzle 14. At the same time, the water source in the housing 21 is the water sprayed from the first atomizing nozzle 13 and the second atomizing nozzle 14 to cool the high-temperature particles. Therefore, when the water inlet in the housing 21 meets the usage requirements, the water in the housing 21 can be recycled by the water pump 18. When the cleaning water in the housing 21 is recycled by the water pump 18, the water supplied by the water pump 18 to the first atomizing nozzle 13 and the second atomizing nozzle 14 has a certain temperature, which further improves the effect of cooling and shaping the high-temperature particles. At the same time, a water replenishment pipe needs to be connected to the liquid inlet pipe 19 to replenish the water source in the housing 21 to ensure that the water volume in the housing 21 meets the usage requirements.

[0043] In operation, the high-temperature granules from the granulator enter the first cooling chamber shell 11. As the high-temperature granules roll within the first cooling chamber shell 11, cooling water sprayed from multiple first atomizing nozzles 13 comes into contact with the granules, achieving initial cooling. After initial cooling, the granules flow into the second cooling chamber shell 12, where cooling water sprayed from multiple second atomizing nozzles 14 further cools them. The granules cooled in the second cooling chamber shell 12 then enter the shell 21. The granules entering the shell 21 fall onto the screening plate 22, where the stirring impeller 28 drives the granules to rotate, improving the screening efficiency of the screening plate 22. As the granules fall through the sieve holes 23, the first magnetic ring 24 and the second magnetic ring 25 adsorb and separate the metallic impurities in the granules. The granules then fall onto the filter screen 26, where the stirring impeller 28 cleans them. During cleaning, small impurities pass through the filter screen 26 and are placed at the bottom of the shell 21, thus completing the screening and cleaning of the granules within the shell 21.
