Description

Technical Field

[0001] The invention relates to the technical field of plastic production, and in particular to a device for uniformly discharging plastic particles. Background Art

[0002] Plastic particles are plastic granules, which refer to granular plastics. Common plastic granules include general-purpose plastics, engineering plastics, and special plastics. There are many processes in the processing of plastic particles.

[0003] Plastic particles may form lumps in the silo due to moisture, static electricity adsorption or long-term accumulation. Especially in a humid environment, plastic particles are easy to absorb moisture and stick together. These lumps may block the outlet of the silo or form bridges in the silo, making it impossible for the plastic particles to flow out smoothly. In addition, during the flow of plastic particles in the pipeline, static electricity is easily generated due to the friction between the particles and the inner wall of the pipeline. When the static electricity accumulates to a certain extent, the plastic particles will adsorb each other or adsorb on the inner wall of the pipeline, which will cause the flow speed of the particles to slow down and even form accumulation on the inner wall of the pipeline, affecting the normal discharge of the materials. In turn, the operator needs to spend a lot of time and energy to discharge the materials, thereby increasing the working time, and the work efficiency is low, which is not convenient for the rapid and uniform discharge of plastic particles. How to invent a plastic particle uniform discharge device to solve these problems has become an urgent problem to be solved by technicians in this field. Summary of the invention

The outer wall of the limiting ring is slidably connected to the fixed plate.

[0019] The beneficial effects of the present invention are:

[0020] 1. When the silo needs to be discharged, the baffle plate can be opened, and then the electric telescopic rod can be controlled to work, driving the support rod to move up, so that the movable ring can be rotated at a certain angle while moving up inside the connecting pipe. While driving the spiral blades and the vertical rod to pass through the butt tube and insert into the bottom of the silo, multiple spiral blades can be rotated at a certain angle around the axis of the movable ring, so as to stir the plastic particles accumulated and agglomerated at the bottom of the silo, so as to disperse and loosen them, thereby promoting the discharge of particles and avoiding accumulation and affecting the discharge. In addition, in the process of the movable ring moving down, the particles adsorbed on the inner wall of the connecting pipe can be scraped off, so as to avoid the particles adhering to the inner wall of the pipe for a long time and affecting the discharge efficiency. When the movable ring moves up, the lifting plate is driven to move up synchronously and the telescopic spring is stretched. When the force of the movable ring on the magnetic block is reduced to the weakest, the telescopic spring drives the lifting plate to move down quickly and return to its position, and makes the impact rod hit the discharge pipe, so that the discharge pipe vibrates, thereby avoiding the particles from adhering to its inner wall due to electrostatic adsorption during the falling process, ensuring the discharge effect and avoiding the accumulation of materials.

[0021] 2. When the lifting plate moves downward, the movable rod will be squeezed first, so that the movable rod drives the screen plate to move downward and compresses the reset spring, shaking the plastic particles that fall on the upper end of the screen plate. This can effectively promote single or smaller particles to fall from the filter holes on the surface of the screen plate to improve the discharging effect and ensure uniform discharging from the inside of the discharging pipe. The shaking can break the adhesion between the particles, so that the particles can be discharged smoothly under the action of vibration. At the same time, it can also block and screen larger impurities and plastic particles that are difficult to disperse due to moisture and stick together, so as to reduce the impact on subsequent processing.

[0022] 3. As the larger particles of impurities accumulate on the surface of the screen plate and the plastic particles that are difficult to disperse due to moisture gradually accumulate, the overall weight of the screen plate will increase, causing the screen plate to gradually compress the reset spring, and the downward movement of the movable rod will also weaken the shaking effect of the screen plate. When the weight of the screen plate increases to a certain extent, the pressure sensor and the fixed plate will be squeezed, triggering the electric heating plate to work, thereby drying the wet and sticky plastic particles. Through heating, the moisture will gradually evaporate, and the bonding force between the particles will decrease due to the reduction of moisture. When the bonding force is reduced to a certain extent, the particles will be redispersed under the action of their own gravity and external vibrations, thereby reducing the accumulation and blockage of excessive particles, while increasing the discharge speed of the particles and avoiding the influence of damp particles on the subsequent processing quality.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1, refer to Figure 1-Figure 10 A plastic particle uniform discharging device comprises a silo 1, a connecting pipe 3 and a discharging pipe 5, one end of the silo 1 is provided with a butt joint pipe 2 and an extension frame 6, a pull rod 7 and a baffle plate 8 are provided inside the extension frame 6, and further comprises:

[0037] A vibration component 4, the vibration component 4 is connected to the connecting pipe 3, and the vibration component 4 is used to remove plastic particles attached to the inner walls of the connecting pipe 3 and the discharge pipe 5;

[0038] A screening component 9, which is located inside the discharge pipe 5 and is used to screen wet and agglomerated plastic particles;

[0039] The discharging assembly 10 is located inside the connecting pipe 3 and is used to loosen the agglomerated plastic particles at the bottom of the silo 1 .

[0040] Furthermore, the lower end of the silo 1 is fixedly connected to the butt joint tube 2, the outer wall of the butt joint tube 2 is fixedly connected to the extension frame 6, the inner wall of the extension frame 6 is slidably connected to the material baffle plate 8, one end of the material baffle plate 8 is fixedly connected to the pull rod 7, the pull rod 7 is slidably connected to the side wall of the extension frame 6, and the plane size of the material baffle plate 8 is larger than the inner circle size of the butt joint tube 2.

[0041] Storage of plastic particles by silo 1: The interior of silo 1 can store plastic particles after production, and a cover plate can be set on the top of silo 1 to reduce the impact of dust on plastic particles. During storage, the baffle plate 8 will block the docking tube 2. When discharging, an external pulling force is applied to the pull rod 7 to pull the pull rod 7 to the side away from the silo 1. After the pull rod 7 moves to the limit position, the baffle plate 8 moves to the inside of the extension frame 6 and no longer blocks the docking tube 2. At this time, the docking tube 2 is fully opened to facilitate the subsequent discharge of plastic particles.

[0042] Furthermore; one end of the connecting pipe 3 is fixedly connected to the butt joint pipe 2, the outer wall of the connecting pipe 3 is provided with a plurality of slide grooves 301 distributed in a circumferential array, the inner wall of the connecting pipe 3 is fixedly connected with a spiral limit block 302, the inner diameter of the connecting pipe 3 is the same as the inner diameter of the butt joint pipe 2, and the end of the connecting pipe 3 away from the butt joint pipe 2 is fixedly connected to the discharge pipe 5.

[0043] Limitation of the lifting plate 401 and the movable ring 1003 by the connecting pipe 3: the connecting pipe 3 can be made of non-magnetic metal material, which can not only ensure the use of the pipeline, but also avoid the influence on the magnetic block 404. In addition, the sliding groove 301 is arranged on the outer wall of the connecting pipe 3 to provide a stabilizing effect for the movement of the lifting plate 401 when it moves up and down, so as to avoid the shaking of the lifting plate 401 when working. In addition, a spiral limiting block 302 is arranged on the inner wall of the connecting pipe 3. On the one hand, it can improve the stability of the movable ring 1003 when moving, and on the other hand, it can also enable the movable ring 1003 to achieve a certain angle of rotation during the up and down movement through the limiting effect, thereby improving the loosening effect of the plastic particles accumulated and agglomerated at the bottom of the silo 1. In addition, the upper end of the connecting pipe 3 and the butt pipe 2 are fixedly connected by multiple bolts, so the two can be easily disassembled and separated, thereby facilitating the maintenance and replacement of the parts inside the connecting pipe 3 and the discharge pipe 5.

[0044] Furthermore, a fixing plate 502 is fixedly connected to the inner wall of the discharge pipe 5, and the fixing plate 502 is arranged in a ring shape. A fixing rod 501 is arranged inside the discharge pipe 5. Two fixing rods 501 are arranged, and the two fixing rods 501 are located above the fixing plate 502. The two fixing rods 501 are rotationally symmetrical about the axial direction of the discharge pipe 5, and one end of the fixing rod 501 is fixedly connected to the inner wall of the discharge pipe 5.

[0045] The discharge pipe 5 supports the screening plate 902 and the electric telescopic rod 1004: a fixed rod 501 is arranged inside the discharge pipe 5 to complete the positioning and support of the electric telescopic rod 1004, thereby ensuring the stability of the entire discharge assembly 10 during movement. In addition, the screening plate 902 can be supported by the cooperation of the fixed plate 502 and the return spring 904. The electric telescopic rod 1004 is controlled by an external controller, and the telescopic distance and frequency of the moving end of the electric telescopic rod 1004 can be controlled by programming.

[0046] Reference Figure 2-Figure 9 , further; the discharging component 10 includes a movable ring 1003, which is slidably connected to the inner wall of the connecting pipe 3, and the outer ring wall of the movable ring 1003 is provided with a slot 1007 which is slidably connected to the spiral limit block 302, the inner ring wall of the movable ring 1003 is fixedly connected to a support frame 1005, the side wall of the support frame 1005 is fixedly connected to a vertical pole 1002, and the outer wall of the vertical pole 1002 is fixedly connected to a spiral blade 1001; the discharging component 10 also includes an electric telescopic rod 1004, the outer wall of the electric telescopic rod 1004 is fixedly connected to one end of the fixed rod 501 away from the inner wall of the discharging pipe 5, one end of the electric telescopic rod 1004 is fixedly connected to a support rod 1006, and one end of the support rod 1006 away from the electric telescopic rod 1004 is rotatably connected to the support frame 1005.

[0047] The discharge assembly 10 is used to loosen the accumulated agglomerated plastic particles at the bottom of the silo 1: when the silo 1 needs to discharge, the baffle plate 8 can be opened, and then the electric telescopic rod 1004 can be controlled to work, driving the support rod 1006 to move up. In this process, through the rotation connection between the support rod 1006 and the support frame 1005, and the limited sliding between the slot 1007 and the spiral limit block 302, the movable ring 1003 can be rotated at a certain angle while moving up inside the connecting pipe 3. While driving the spiral blades 1001 and the vertical rod 1002 to pass through the docking pipe 2 and insert into the bottom of the silo 1, the multiple spiral blades 1001 rotate around the axis of the movable ring 1003 at a certain angle, thereby loosening the accumulated agglomerated plastic particles at the bottom of the silo 1. The agglomerated plastic particles are stirred to disperse and loosen them, thereby promoting the discharge of particles and avoiding accumulation that affects discharge. When the movable ring 1003 moves to be flush with the upper end of the spiral limit block 302, the movable end of the electric telescopic rod 1004 stops extending and begins to retract. During the downward movement of the movable ring 1003, the particles adsorbed on the inner wall of the connecting pipe 3 can be scraped off, thereby avoiding the particles from adhering to the inner wall of the pipe for a long time and affecting the discharge efficiency. When the movable end of the electric telescopic rod 1004 returns to the initial position (that is, the movable ring 1003 is flush with the lower end of the spiral limit block 302), it starts to drive the movable ring 1003 to move up again, thereby working in a reciprocating motion. When discharge is not needed, the external power supply is turned off and reset.

[0048] Furthermore; the vibration component 4 includes a lifting plate 401, which is sleeved on the outer wall of the connecting pipe 3, and the lifting plate 401 slides between the sliding groove 301, and the inner circle of the lifting plate 401 is fixedly connected with a magnetic block 404, and the magnetic block 404 is arranged in an arc shape; the vibration component 4 also includes a telescopic spring 402 and an impact rod 403, and a plurality of telescopic springs 402 and impact rods 403 are provided, and the plurality of telescopic springs 402 and impact rods 403 are distributed in an array around the axis of the lifting plate 401, and each impact rod 403 is located between two adjacent telescopic springs 402, and one end of the impact rod 403 is fixedly connected to the side wall of the lifting plate 401, and the two ends of the telescopic spring 402 are respectively fixedly connected to the side wall of the lifting plate 401 and one end of the discharge pipe 5.

[0049] The impact rod 403 removes particles attached to the inner wall of the pipeline: in the initial state, the lifting plate 401 and the movable ring 1003 are in the same horizontal plane, and the movable ring 1003 can be made of magnetic material and attract each other with the magnetic block 404 through magnetism. Therefore, in the process of the movable ring 1003 moving upward, the lifting plate 401 is driven to move upward synchronously through the effect of magnetism. In this process, the slide groove 301 not only ensures the stability of the movement process of the lifting plate 401, but also limits the upward height of the lifting plate 401, and stretches the telescopic spring 402 when the lifting plate 401 rises. When the lifting plate 401 moves to the limited position of the slide groove 301, it will no longer rise, while the movable ring 1003 will continue to move upward. When the movable ring 1003 and the lifting plate 401 are misaligned and are no longer in the same horizontal plane, the force of the movable ring 1003 on the magnetic block 404 is weakened at this moment. When 1003 moves to the highest point, the force exerted on the magnetic block 404 is the weakest. At this time, the elastic force of the telescopic spring 402 is greater than the force between the two. Therefore, the elastic recovery of the telescopic spring 402 drives the lifting plate 401 to move down quickly and return to its position, and the impact rod 403 hits the discharge pipe 5 through the action of elastic potential energy, causing the discharge pipe 5 to vibrate, thereby preventing particles from adhering to its inner wall due to electrostatic adsorption during the falling process, ensuring the discharge effect and avoiding the accumulation of materials. The discharge pipe 5 is also made of metal material, which can ensure the transmission of the vibration effect on the object. In addition, the lifting plate 401 and the telescopic spring 402 will gradually reset through external resistance, waiting for the next cooperation with the movable ring 1003. When the movable ring 1003 moves down to a certain range, it may drive the lifting plate 401 to fluctuate up and down through magnetism, but the range of movement does not affect the final reset result.

[0050] Example 2, refer to Figure 2 , Figure 4 , Figure 7 , Figure 8 and Fig.10 , further; the screening assembly 9 includes a screening plate 902, the screening plate 902 is located above the fixed plate 502, the screening plate 902 is slidably connected to the inner wall of the discharge pipe 5, the upper end of the screening plate 902 is fixedly connected with a movable rod 901, and two movable rods 901 are rotationally symmetrical about the axis of the screening plate 902, and one end of the movable rod 901 away from the screening plate 902 vertically penetrates the side wall of the discharge pipe 5, the upper end of the movable rod 901 is located on the inner side of the telescopic spring 402, and the length of the movable rod 901 located on the outside of the discharge pipe 5 is greater than the length of the impact rod 403, and one end of the screening plate 902 close to the fixed plate 502 is fixedly connected with a plurality of return springs 904 distributed in a circular array, and the end of the return spring 904 away from the screening plate 902 is fixedly connected to the side wall of the fixed plate 502.

[0051] Screening of plastic particles by screening plate 902: Since the length of movable rod 901 outside discharge pipe 5 is greater than the length of impact rod 403 itself, and the elastic coefficient of return spring 904 is smaller than the elastic coefficient of telescopic spring 402, it is easier to be compressed, and the deformation of both is within the elastic limit, and the same material is used for both. Therefore, when lifting plate 401 moves downward rapidly through telescopic spring 402, lifting plate 401 will first squeeze movable rod 901, so that movable rod 901 drives screening plate 902 to move downward and return spring 904 is compressed. In this process, return spring 904 will only be squeezed a little. Part, and with the stop of the movement of the lifting plate 401, the reset spring 904 drives the screen plate 902 and the movable rod 901 to reset, thereby shaking the plastic particles that have fallen on the upper end of the screen plate 902, which can effectively promote single or smaller particles to fall from the filter holes on the surface of the screen plate 902, so as to improve the discharging effect and ensure uniform discharging from the inside of the discharge pipe 5. The shaking can break the adhesion between the particles, so that the particles can be discharged smoothly under the action of vibration. At the same time, larger impurities and plastic particles that are difficult to disperse due to adhesion due to moisture can be blocked and screened to reduce the impact on subsequent processing.

[0052] Furthermore; a pressure sensor 905 is fixedly connected to the side wall of the screening plate 902, and the pressure sensor 905 is located between two adjacent reset springs 904. An electric heating plate 906 is provided inside the screening plate 902. A limiting ring 903 is fixedly connected to the side wall of the screening plate 902. The limiting ring 903 is arranged in a "convex" shape as a whole, and the outer wall of the limiting ring 903 is slidingly connected to the fixed plate 502.

[0053] Pressure sensor 905 and electric heating plate 906 disperse the plastic particles that are bonded together: As the larger impurities accumulated on the surface of the screen plate 902 and the plastic particles that are bonded together and difficult to disperse due to moisture gradually accumulate, the overall weight of the screen plate 902 will increase, so that the screen plate 902 gradually compresses the reset spring 904, and the downward movement of the movable rod 901 will also weaken the shaking effect of the screen plate 902. When the weight of the screen plate 902 increases to a certain extent, the pressure sensor 905 and the fixed plate 50 2-phase extrusion, and the pressure sensor 905 is electrically connected to the electric heating plate 906, so the electric heating plate 906 can be triggered to work, thereby drying the wet and sticky plastic particles. Through heating, the moisture will gradually evaporate, and the bonding force between the particles will decrease due to the reduction of moisture. When the bonding force is reduced to a certain extent, the particles will be redispersed under the influence of their own gravity and external vibrations, thereby reducing the accumulation and blockage of excessive particles, while increasing the discharge speed of the particles and preventing the damp particles from affecting the subsequent processing quality;

[0054] In addition, the heating temperature of the electric heating plate 906 can be reasonably adjusted according to the material of the specific plastic particles. If the temperature is too low, the evaporation rate of water is too slow, it takes a long time to remove the water, and it may not be possible to completely destroy the bonding force between the particles. For example, for some common thermoplastic plastic particles, such as polyethylene (PE), the heating temperature can generally be set at 60-80°C. This temperature range can ensure the effective evaporation of water without causing excessive thermal deformation or chemical changes in the plastic particles themselves. However, if the temperature is too high and exceeds the thermal stability temperature of the plastic particles, the plastic may degrade, discolor, melt, etc. For example, polyvinyl chloride (PVC) may decompose and produce hydrogen chloride gas when it exceeds 140°C, which will not only affect the performance of the plastic particles, but also may damage the drying equipment. Therefore, when using the electric heating plate 906, the heating temperature must be controlled within a reasonable range, and the air flow will be driven during the particle discharge process, which is conducive to taking away the evaporated water and improving the drying efficiency.

[0055] In addition, the screening plate 902 can be made of metal. The metal itself has good thermal conductivity, and the heat transfer is rapid and uniform. The plastic particles can be quickly heated to the required temperature. The heating temperature can be precisely controlled by conveniently changing the power, current and other parameters of the heating element to meet the requirements of different plastic particle processing techniques. Moreover, the metal material generally has high mechanical strength and toughness, can withstand large pressure differences and particle impacts, and is not easily broken or damaged.

[0056] It should be noted that the specific model specifications of the components need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
