Description

Technical Field

[0001] This utility model belongs to the technical field of single-screw granulators, and specifically relates to a discharging mechanism for a single-screw granulator. Background Technique

[0002] In many industries such as plastics, rubber, and chemical engineering, single-screw granulators are commonly used production equipment for processing raw materials into granular products. However, during the discharging process of existing single-screw granulators, there are often a series of problems, which affect the quality of the final product and production efficiency.

[0003] When the traditional discharging mechanism of a single-screw granulator discharges particles, it usually cannot effectively remove the dust and impurities attached to the particle surface. The existence of these impurities not only affects the purity of the product but may also cause a series of quality problems during subsequent processing or use. For example, in the production of plastic products, impurities may lead to a decline in the physical properties of the products and appearance defects.

[0004] At the same time, the existing discharging mechanism is also difficult to effectively separate non-conforming particles from conforming particles. If non-conforming particles (such as particles with too small a diameter) are mixed with conforming particles, it will result in uneven particle size distribution of the product, affecting the consistency and performance stability of the product. This will have serious adverse effects in application scenarios with high requirements for particle specifications, such as the production of high-precision plastic products and the manufacturing of high-end rubber products.

[0005] In addition, due to the lack of effective impurity removal and particle specification screening mechanisms, additional post-treatment processes are often required during the production process to solve these problems. This not only increases production costs but also reduces production efficiency and prolongs the production cycle.

[0006] Therefore, we have proposed a discharging mechanism for a single-screw granulator. This device can not only remove impurities and dust on the particles but also separate non-conforming particles from conforming particles, thereby improving the quality of the product. Content of the Utility Model

[0007] The purpose of this utility model is to provide a discharging mechanism for a single-screw granulator. This device can not only remove impurities and dust on the particles but also separate non-conforming particles from conforming particles, thereby improving the quality of the product.

[0008] The technical solution adopted by this utility model is specifically as follows:

[0009] A discharging mechanism for a single-screw granulator includes a bracket. A cylinder is arranged at the top of the bracket. A screw assembly is arranged inside the cylinder, and a cleaning assembly for impurity removal is arranged at the top of the cylinder.

[0010] The cleaning component includes a first housing disposed on the cylinder body. A fixing frame is arranged inside the first housing, and a cylindrical housing is arranged on the fixing frame. An air guiding component and a plurality of connecting pipes are arranged on the cylindrical housing. One end of each connecting pipe away from the cylindrical housing is provided with a spiral conveyor plate. A cavity communicating with the connecting pipe is formed on the spiral conveyor plate, and a through hole communicating with the cavity is arranged on the spiral conveyor plate.

[0011] Furthermore, a discharge pipe is arranged on the cylinder body.

[0012] Furthermore, the screw component includes a first motor arranged on the cylinder body. The output end of the first motor is provided with a first rotating shaft located inside the cylinder body, and a spiral tooth is sleeved on the first rotating shaft.

[0013] Furthermore, a sealing disc is arranged at the bottom of the cylindrical housing in a threaded manner. A support rod is arranged on the top of the sealing disc, a filter disc is installed on the top of the support rod, and a rotating rod is arranged at the bottom of the sealing disc.

[0014] Furthermore, the air guiding component includes a second motor arranged on the cylindrical housing. The output end of the second motor is provided with a fan blade located inside the cylindrical housing.

[0015] Furthermore, exhaust holes are formed on the cylindrical housing.

[0016] Furthermore, a feed pipe is arranged on the first housing.

[0017] The technical effects achieved by this utility model are as follows:

[0018] Firstly, the particles generated by the granulator enter the spiral conveyor plate. Since the spiral conveyor plate is of a spiral structure, the entering particles will slide on the spiral conveyor plate. Meanwhile, the air guiding component is started. During the sliding process, the particles collide with each other and with the through holes. At this time, the dust and impurities on the particles will fall off due to the collision force. Then, the air guiding component provides a force to generate suction inside the cavity, so that the fallen impurities and dust enter the inside of the cylindrical housing through the connecting pipe for collection. At the same time, some particles that do not meet the specifications (such as particles with a very small diameter) will enter the cavity through the through holes for collection, so as to separate the particles that do not meet the specifications from the particles that meet the specifications, thereby improving the quality of the generated particles. These particles that meet the specifications enter the inside of the cylinder body and are then conveyed and discharged through the screw component. This device can not only remove the impurities and dust on the particles, but also separate the particles that do not meet the specifications from the particles that meet the specifications, thereby improving the quality of the generated particles.

Specific embodiments

[0026] In order to make the purpose and advantages of the present utility model more clear and understandable, the following specifically describes the present utility model in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.

[0027] As Figures 1-5 shown, the technical solution adopted by the present utility model is specifically as follows: A discharge mechanism for a single-screw granulator, including a support 1, a cylinder 2 is arranged at the top of the support 1, a screw assembly is arranged inside the cylinder 2, and a cleaning assembly for removing impurities is arranged at the top of the cylinder 2;

[0028] The cleaning assembly includes a first shell 3 arranged on the cylinder 2, a fixing frame 4 is arranged inside the first shell 3, a cylindrical shell 5 is arranged on the fixing frame 4, an air guiding assembly and a plurality of connecting pipes 6 are arranged on the cylindrical shell 5, one end of each connecting pipe 6 away from the cylindrical shell 5 is provided with a spiral conveyor plate 7, a cavity 8 communicating with the connecting pipe 6 is formed on the spiral conveyor plate 7, and a through hole 9 communicating with the cavity 8 is arranged on the spiral conveyor plate 7.

[0029] Its working principle is as follows: First, the particles produced by the granulator enter the spiral conveyor plate 7. Since the spiral conveyor plate 7 is of a spiral structure, the entering particles will slide on the spiral conveyor plate 7. At the same time, the air induction component is started. When sliding, the particles collide with each other and with the through holes 9. At this time, the dust and impurities on the particles will be shed by the collision force. Then, the air induction component provides a force to generate suction inside the cavity 8, so that the shed impurities and dust enter the inside of the cylindrical shell 5 through the connecting pipe 6 for collection. At the same time, some particles that do not meet the specifications (such as particles with a very small diameter) will enter the cavity 8 through the through holes 9 for collection, so as to separate the particles that do not meet the specifications from the particles that meet the specifications, thereby improving the production quality. These particles that meet the specifications enter the inside of the cylinder body 2 and are then conveyed and discharged through the screw component. This device can not only remove the impurities and dust on the particles, but also separate the particles that do not meet the specifications from the particles that meet the specifications, thereby improving the production quality.

[0030] Among them, a discharge pipe 10 is provided on the cylinder body 2, and the particles are discharged through the discharge pipe 10.

[0031] At the same time, the screw component includes a first motor 11 provided on the cylinder body 2. The output end of the first motor 11 is provided with a first rotating shaft located inside the cylinder body 2. A spiral tooth 12 is sleeved on the first rotating shaft. The spiral tooth 12 conveys the particles by driving the first rotating shaft through the first motor 11.

[0032] The first housing 3 is composed of a cylindrical housing and a conical housing. Such a setting can quickly introduce the particles into the inside of the cylinder body 2.

[0033] The bottom of the cylindrical shell 5 is provided with a sealing disk 13 in a threaded manner. A support rod 14 is provided on the top of the sealing disk 13. A filter disk 15 is installed on the top of the support rod 14, and a rotating rod is provided at the bottom of the sealing disk 13. Such a setting can facilitate the installation and disassembly of the filter disk 15. By providing the filter disk 15, the inhaled dust and impurities can be filtered to prevent damage to the air induction component.

[0034] The air induction component includes a second motor 16 provided on the cylindrical shell 5. The output end of the second motor 16 is provided with a fan blade 17 located inside the cylindrical shell 5. The fan blade 17 is driven to rotate by the second motor 16, thereby providing suction.

[0035] An exhaust hole 18 is provided on the cylindrical shell 5, and the air circulates through the exhaust hole 18.

[0036] A feed pipe 19 is provided on the first housing 3, and the particles enter through the feed pipe 19.

[0037] A sealing plate for sealing the cavity 8 is provided at the discharge port of the spiral conveying plate 7. Through the sealing plate, particles that do not meet the specifications inside the cavity 8 can be blocked to prevent them from flowing into the inside of the cylinder body 2. When cleaning is required, only the sealing plate needs to be removed.

[0038] The working principle of this utility model is as follows: First, the particles generated by the granulator enter the spiral conveying plate 7. Since the spiral conveying plate 7 is of a spiral structure, the entering particles will slide on the spiral conveying plate 7. At the same time, the air guiding component starts. During the sliding process, the particles collide with each other and with the through holes 9. At this time, the dust and impurities on the particles will be shed by the collision force. Then, the air guiding component provides a force to generate suction inside the cavity 8, so that the shed impurities and dust enter the inside of the cylindrical shell 5 through the connecting pipe 6 for collection. At the same time, some particles that do not meet the specifications (such as particles with a very small diameter) will enter the cavity 8 through the through holes 9 for collection, so as to separate the particles that do not meet the specifications from the particles that meet the specifications, thereby improving the quality of production. These particles that meet the specifications enter the inside of the cylinder body 2 and are then conveyed and discharged through the screw component. This device can not only remove the impurities and dust on the particles, but also separate the particles that do not meet the specifications from the particles that meet the specifications, thereby improving the quality of production.

[0039] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
