Description

Technical Field

[0001] The invention relates to the technical field of screening equipment, in particular to an environmentally friendly peptizer particle screening machine. Background Art

[0002] With the enhancement of environmental awareness and the advancement of green development, environmentally friendly plasticizers have gradually been favored by the market as an alternative to traditional toxic plasticizers. Plasticizers are chemicals used to improve the processing performance of plastics, reduce processing temperatures, and increase the softness of plastic products. Environmentally friendly plasticizers not only have the functions of traditional plasticizers, but also have less impact on human health and the environment during production, use and disposal, and meet the requirements of sustainable development.

[0003] In the production process of environmentally friendly plasticizers, the size and distribution of particles have an important impact on the final performance of the product. The uniformity of particle size is not only related to the stability and processing adaptability of the product, but also directly affects the user experience and production efficiency. Therefore, effective screening of environmentally friendly plasticizer particles is one of the key links to ensure product quality.

[0004] The traditional screening of plasticizers is generally achieved by using structures such as vibrating screens and sieve plates. When in use, plasticizers mixed with different particle sizes are poured into the machine. The sieve holes in the machine screen the plasticizers. Plasticizers that meet the particle size requirements pass through the sieve holes, while plasticizers with larger particles are intercepted by the sieve holes, thereby achieving screening. However, this screening method can only achieve one screening, and cannot perform multiple types of screening according to particle size. Moreover, during screening, only the bottom layer of plasticizers close to the sieve hole position can be screened, and the upper layer of plasticizers needs to wait, which leads to low screening efficiency.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 7As shown, an environmentally friendly plasticizer particle screening machine of the present invention comprises a screening box 1, an air supply structure 2, a bulk material structure 3 and a bottom bin 4, wherein the screening box 1 is used to provide space for the screening of plasticizer particles, the air supply structure 2 is used to fill air into the screening box 1, the bulk material structure 3 is used to feed the plasticizer particles into the screening box 1 and scatter the plasticizer particles around, the bottom bin 4 is installed at the bottom of the screening box 1, a plurality of annular material troughs 5 are opened in the bottom bin 4, the top of the annular material trough 5 penetrates into the screening box 1, the plurality of annular material troughs 5 are coaxial and mutually sleeved, the diameters of the plurality of annular material troughs 5 increase successively, the bottom of the bottom bin 4 is inclined, and the bottom of the bottom bin 4 is connected to a plurality of discharge pipes 6, and the plurality of discharge pipes 6 are respectively connected to the plurality of annular material troughs 5; The air discharged into the screening box 1 by the air supply structure 2 flows from the inner wall of the screening box 1 toward the axial direction of the screening box 1 .

[0020] In detail, the axis of the screening box 1 is vertical, and the plasticizer particles are screened in the screening box 1. The air supply structure 2 is installed in the middle or upper side of the screening box 1. The air supply structure 2 supplies air into the screening box 1, and the airflow flows from all sides to the axis direction of the screening box 1 in the screening box 1. The bulk structure 3 is installed on the top of the screening box 1. The plasticizer particles are introduced into the screening box 1 through the bulk structure 3, and the bulk structure 3 scatters the plasticizer particles to all sides, thereby providing the plasticizer particles with inertial force for horizontal movement. The multiple annular troughs 5 on the bottom bin 4 are used to receive plasticizers of different particle sizes. Since the bottom of the bottom bin 4 is inclined, the plasticizer particles received by the annular troughs 5 can gather to the discharge pipe 6 and be discharged through the discharge pipe 6.

[0021] When in use, the bulk structure 3 scatters the peptizer particles toward the inner wall of the screening box 1, and the peptizer particles move downward under the action of gravity. The air supply structure 2 supplies air into the screening box 1. In the horizontal direction, the airflow flows in the opposite direction to the peptizer particles, and the airflow blows the peptizer particles. The peptizers with larger particles have greater inertia and are less affected by the airflow, while the peptizers with smaller particles have smaller inertia and are more easily affected by the airflow. Therefore, the peptizers with larger particles move downward near the inner wall of the screening box 1, while the peptizers with smaller particles move toward the axis of the screening box 1. In this way, the peptizers of different particle sizes can move different distances in the horizontal direction, so that the peptizers fall into different annular troughs 5 according to their particle sizes, thereby realizing a more detailed screening of the peptizer particles. The peptizer particles can be divided into multiple categories at one time, and this screening method can realize large-scale and continuous screening of the peptizer particles.

[0022] Since the airflow is in the opposite direction to the initial scattering direction of the peptizer particles, the inertial force of the peptizer particles can be more prominent in the airflow, thereby classifying and screening the peptizer particles more clearly.

[0023] Through the airflow guide design and multi-level sieve hole layout, the screening machine can complete multi-level screening work at one time, greatly improving the screening efficiency. Compared with the traditional single sieve hole screening method, it can process a large number of plasticizer particles at the same time, realize the rapid screening function, and avoid the problem of upper plasticizer waiting for screening and time waste; using the relationship between the size and inertia of plasticizer particles, combined with the reverse flow of airflow relative to the moving direction of plasticizer particles, the inertia phenomenon of plasticizer particles can be more prominent, so as to achieve more effective screening of plasticizer particles and facilitate the separation of particles of different sizes, which enables the final product to achieve higher purity and consistency, meeting the market demand for high-quality plasticizers; the design of the screening machine allows continuous feeding and screening of plasticizer particles, avoiding the limitation of intermittent operation of traditional screening machines, and further improving production efficiency and production capacity; in summary, this new type of plasticizer particle screening machine not only solves the problems of low efficiency and insufficient screening accuracy of traditional screening technology through innovative airflow control and multi-level screening design, but also achieves more efficient, finer and more environmentally friendly screening effects.

[0024] Furthermore, the bulk material structure 3 includes a vertical pipe 7, which is vertically inserted into the screening box 1, and a plurality of bulk material channels 8 are provided in an annular shape on the vertical pipe 7, and the plurality of bulk material channels 8 are all located in the screening box 1; The vertical plane where the bulk material channel 8 is located coincides with the axis of the vertical pipe 7 , the end opening of the bulk material channel 8 away from the vertical pipe 7 is vertically flat, and the bulk material channel 8 is inclined upward in the direction away from the vertical pipe 7 .

[0025] In detail, the peptizer particles can be introduced into the screening box 1 through the vertical pipe 7 and multiple bulk channels 8. When the vertical pipe 7 rotates, the vertical pipe 7 can drive the multiple bulk channels 8 to rotate. The multiple bulk channels 8 can centrifugally scatter the peptizer particles therein to the surroundings, thereby making the peptizer particles evenly dispersed. Moreover, since the end opening of the bulk channel 8 away from the vertical pipe 7 is vertically flat, the bulk channel 8 can realize the dispersion of the peptizer particles in the vertical direction. Compared with the horizontally dispersed scattering method in the traditional method, the bulk channel 8 in this case can increase the scattering range of the peptizer particles in space, thereby reducing the mutual occlusion problem between the peptizer particles, increasing the processing amount of the peptizer particles, and thus improving the processing efficiency. Since the bulk channel 8 is inclined upward, the upward projection effect of the peptizer particles can be achieved, thereby extending their falling time.

[0026] Furthermore, a support plate 9 is fixed on each bulk material channel 8, and a baffle 10 is slidably inserted on the support plate 9, and the baffle 10 is used to control the size of the end opening of the bulk material channel 8 away from the vertical pipe 7; The baffle plate 10 moves on a horizontal plane in a direction perpendicular to the bulk material channel 8 .

[0027] In detail, when the baffle 10 moves on the support plate 9, the blocking area of ​​the opening of the bulk material channel 8 by the baffle 10 changes, thereby adjusting the size of the opening of the bulk material channel 8, and this adjustment method ensures that the shape of the opening of the bulk material channel 8 is always flat. In this way, when the amount of material in the vertical pipe 7 is small, the opening of the bulk material channel 8 is reduced, while the way in which the bulk material channel 8 scatters the material remains unchanged. When the amount of material in the vertical pipe 7 is large, the opening of the bulk material channel 8 is increased, thereby avoiding the situation where when there is less material in the vertical pipe 7, the material is gathered on the lower side of the bulk material channel 8 and discharged through the lower area of ​​the bulk material channel 8 opening, while the middle or upper area of ​​the bulk material channel 8 opening cannot be utilized.

[0028] Furthermore, each of the baffles 10 is provided with a connecting column 11, and an adjusting arm 12 is rotatably provided on the connecting column 11; A rotating ring 13 is rotatably sleeved on the outer wall of the vertical tube 7, and the adjusting arm 12 is rotatably connected to the rotating ring 13. A movable support 14 is arranged in the vertical tube 7, and the bottom of the movable support 14 extends beyond the vertical tube 7. A plurality of insertion rods 15 are arranged on the movable support 14, and the insertion rods 15 are vertically slidably inserted on the rotating ring 13. The movable support 14 provides an upward elastic thrust through a spring 16; A spiral groove is provided on the outer wall of the movable support platform 14, and a spiral edge is provided on the inner wall of the vertical pipe 7, and the spiral edge slides in the spiral groove.

[0029] In detail, the top of the movable support 14 in the vertical tube 7 is used to carry the plasticizer granular material. When there is a lot of material in the vertical tube 7, the movable support 14 moves downward due to the gravity of the material, and the spring 16 is elastically deformed. Due to the action of the spiral groove and the spiral edge, the movable support 14 rotates when moving downward. The movable support 14 drives the rotating ring 13 to rotate through the insertion rod 15, and the insertion rod 15 slides in the vertical direction relative to the rotating ring 13. The rotating ring 13 can drive the baffle 10 to move through the adjusting arm 12 and the connecting column 11, thereby increasing the opening size of the bulk material channel 8. When there is less material in the vertical tube 7, the spring 16 provides an upward elastic thrust for the movable support 14, thereby moving the baffle 10 and reducing the opening size of the bulk material channel 8.

[0030] Furthermore, a core shaft 17 is rotatably disposed in the vertical tube 7, and a plurality of fan plates 18 are disposed on the outer wall of the core shaft 17. The rotation direction of the core shaft 17 is opposite to that of the vertical tube 7. The movable support 14 is hollow inside, the spring 16 is located inside the movable support 14 , the bottom of the core shaft 17 is slidably inserted into the movable support 14 , and the bottom of the core shaft 17 is rotatably provided with a chassis 19 , one end of the spring 16 is connected to the movable support 14 , and the other end of the spring 16 is connected to the chassis 19 .

[0031] In detail, the spring 16 is sleeved on the core shaft 17 in the movable support platform 14 , and the core shaft 17 and the chassis 19 can be used to support the spring 16 , and the spring 16 provides an upward thrust for the movable support platform 14 .

[0032] When the core shaft 17 rotates, it can drive multiple fan plates 18 to rotate synchronously. The fan plates 18 provide initial centrifugal thrust for the material in the vertical pipe 7. Since the vertical pipe 7 and the core shaft 17 rotate in opposite directions, the material moves faster relative to the vertical pipe 7, thereby increasing the distance that the material is discharged through the bulk channel 8 and improving the material dispersion effect.

[0033] When the vertical tube 7 rotates, the vertical tube 7 will drive the movable support platform 14 to rotate synchronously, and the core shaft 17 and the movable support platform 14 rotate relatively, so that the chassis 19 needs to be rotationally connected with the core shaft 17.

[0034] Furthermore, a cover plate 20 is installed on the top cover of the vertical pipe 7, and the vertical pipe 7 and the core shaft 17 are both rotatably connected to the cover plate 20. A feed pipe 21 and a motor 22 are provided on the cover plate 20. The feed pipe 21 and the motor 22 are both fixed to the screening box 1 through a fixing plate 23. The feed pipe 21 is used to feed materials into the vertical pipe 7. A transmission wheel 24 is provided at the output end of the motor 22. The transmission wheel 24 is located in the vertical pipe 7, and the transmission wheel 24 is respectively connected to the vertical pipe 7 and the core shaft 17 in a transmission manner.

[0035] In detail, the fixed plate 23 can support the cover plate 20, and the cover plate 20 can support the core shaft 17. The material can be introduced into the vertical pipe 7 through the feed pipe 21. The motor 22 and the transmission wheel 24 can provide power in opposite directions of movement to the core shaft 17 and the vertical pipe 7.

[0036] Furthermore, the air supply structure 2 includes an outer ring 25 disposed on the outer wall of the screening box 1, the outer ring 25 is hollow inside, the outer ring 25 is connected to the screening box 1, and an air inlet pipe 26 is disposed on the outer ring 25; A retaining ring 27 is fixed inside the outer ring 25, and a plurality of air holes 28 are formed on the retaining ring 27. A sliding ring 29 is sleeved on the outer wall of the retaining ring 27, and the sliding ring 29 covers the plurality of air holes 28. The top of the sliding ring 29 is inclined, and the bottom of the sliding ring 29 passes through the outer ring 25 and extends outside the outer ring 25. The sliding ring 29 and the outer ring 25 are connected by a plurality of spring pieces 30. When air is supplied to the outer ring 25, the air pressure acts on the top of the sliding ring 29 and causes it to move downward.

[0037] In detail, the air inlet pipe 26 can transport air into the outer ring 25. As the air increases, the air pressure increases, and the pressure acts on the top inclined surface of the sliding ring 29 and causes the sliding ring 29 to move downward. At this time, the spring piece 30 undergoes elastic deformation, and the multiple air holes 28 on the retaining ring 27 are gradually exposed. The air in the outer ring 25 can be supplied into the screening box 1 through the multiple air holes 28, thereby realizing the air supply work.

[0038] It should be pointed out that, due to the use of the sliding ring 29 and the spring 30, the air pressure entering the multiple air holes 28 can be made the same, thereby achieving the effect of pressure equalization, making it convenient to make the pressure and flow rate of the air flows discharged into the screening box 1 in different directions the same, and avoiding the situation where, when the air inlet pipe 26 supplies air to the outer ring 25, the air pressure of the air holes 28 close to the air inlet pipe 26 is higher, while the air pressure of the air holes 28 far away from the air inlet pipe 26 is lower.

[0039] Furthermore, two guide rings 31 are disposed opposite to each other on the inner wall of the screening box 1 . The cross-section of the guide ring 31 is arc-shaped. The two guide rings 31 are respectively located at the upper and lower sides of the position where the outer ring 25 is connected to the screening box 1 .

[0040] In detail, when the airflow is blown into the screening box 1 between the two guide rings 31, the airflow will flow along the curved surface of the guide ring 31, thereby increasing the airflow diffusion area, making it easier for the airflow to blow the plasticizer particles in the projectile state over a large area.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
