Description

Technical Field

[0002] Plastic is a common polymer material. During the production process, plastic particles are extruded by an extruder and then cooled by water. After cooling, the formed plastic needs to be cut into particles. Since there will be residual moisture on the surface of the plastic particles after the plastic is cooled and cut directly, a dehydration device is needed to dehydrate the surface of the plastic particles.

[0003] For example, a Chinese patent document with publication number CN218576718U discloses an improved dehydration device, comprising: an outer shell, a dehydration inner tank and two driving mechanisms, wherein an electric heater is installed in the outer shell; the dehydration inner tank comprises a cylindrical feed pipe and a dehydration pipe with a double-layer shell structure, wherein the feed pipe is connected to the outer shell, a plurality of discharge holes are provided at the bottom of the shell of the dehydration pipe, a dehydration hole is provided on the outer wall of the dehydration pipe, and a plurality of spiral plates are evenly installed in the dehydration pipe.

[0004] In the above technical solution, a double-layer conical dehydration pipe is provided, and a spiral dehydration space is provided in the dehydration pipe, so that the plastic particles can be heated and dried by the electric heater while being spun dry, and dehydration and drying are carried out simultaneously, thereby increasing the dehydration speed of the plastic particles, improving work efficiency, and saving working time. After the particles are dehydrated, the particles are discharged through the discharge pipe. However, the volume of the discharge pipe is much smaller than the volume of the dehydration tank, which can easily cause the particles to cause blockage of the discharge pipe during discharge. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a dehydration device for pellet processing, which can prevent pellets from being blocked during discharge and improve the discharge efficiency of the pellets.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dehydration device for processing particles, comprising a cylinder and a driving device, a cavity is provided in the cylinder, a discharge port connected to the cavity is provided at the bottom of the cylinder, a rotatable dehydration liner is provided in the cavity, the driving device is used to drive the dehydration liner to rotate, the dehydration liner is a hollow structure to form a discharge channel inside, the discharge channel is opposite to the discharge port, the inner diameter of the discharge channel is matched with the inner diameter of the discharge port, a cylinder is provided above the dehydration liner, a shielding plug is fixed to the output end of the cylinder, the shielding plug is vertically opposite to the discharge channel, and the cylinder is used to drive the shielding plug to move in the vertical direction to open or close the discharge port.

[0007] The utility model is further configured as follows: the dehydration inner container is located on a side facing the discharge port, and the inner diameter decreases in sequence along the direction toward the discharge port to form a shielding end.

[0008] The utility model is further configured as follows: the shielding plug is provided with a material guiding side wall on the side facing away from the material outlet, the inner diameter of which decreases successively in the direction away from the material outlet.

[0009] The utility model is further configured as follows: the driving device includes a gear ring fixed on the outer periphery of the dehydration inner tank, the top of the cylinder is rotatably connected to a driving shaft, the outer periphery of the driving shaft is fixed with transmission teeth, the transmission teeth are meshed with the gear ring, and a motor is connected to the driving shaft, the motor is used to drive the transmission teeth to rotate, thereby driving the dehydration inner tank to rotate.

[0010] The utility model is further configured as follows: an annular guide rail is fixedly mounted on the outer periphery of one end of the dehydration inner tank close to the discharge port, a guide wheel is connected to rotate vertically in the cavity, there are multiple guide wheels which are evenly distributed on the outer periphery of the annular guide rail in a circular manner, the guide wheels are coupled to the annular guide rail, and can form a guiding fit with each other.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By setting the inner wall to be a hollow structure to form a dehydration inner tank with a discharge channel inside and a shielding plug for shielding the dehydration inner tank, when discharging the dehydrated particles, the shielding plug is moved upward to open the discharge channel, so that the entire discharge channel can be used as a discharge space. Therefore, the technical problem that the discharge method through the discharge pipe in the prior art is prone to blockage is effectively solved, thereby preventing the particles from being blocked during discharge and improving the discharge efficiency of the particles. When dehydrating the particles, the shielding plug can be moved downward to close the discharge channel, and the dehydration inner tank can be driven by the driving device to rotate at a high speed, so that the moisture on the surface of the particles is thrown out under the centrifugal action to complete the dehydration of the particles. Therefore, the shielding plug is driven by the cylinder to move in the vertical direction, so that the discharge channel can be opened and closed, making the switching of the overall equipment between dehydration and discharge faster and more convenient.

[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] like Figures 1 to 3 As shown, the utility model discloses a dehydration device for processing pellets, including a cylinder 1 and a driving device. A cavity 101 is provided in the cylinder 1. A discharge port 102 communicating with the cavity 101 is provided at the bottom of the cylinder 1. A rotatable dehydration liner 2 is provided in the cavity 101. The driving device is used to drive the dehydration liner 2 to rotate. The dehydration liner 2 is a hollow structure to form a discharge channel 21 inside. The discharge channel 21 is opposite to the discharge port 102. The inner diameter of the discharge channel 21 is matched with the inner diameter of the discharge port 102. A cylinder 3 is provided above the dehydration liner 2. A shielding plug 4 is fixed to the output end of the cylinder 3. The shielding plug 4 is vertically opposite to the discharge channel 21. The cylinder 3 is used to drive the shielding plug 4 to move in the vertical direction to open or close the discharge port 102. When discharging the dehydrated pellets, By moving the shielding plug 4 upward to open the discharge channel 21, the entire discharge channel 21 can be used as a discharge space to increase the discharge volume, and the discharge space surrounds the shielding plug 4 to prevent the particles from gathering in one place during discharge, thereby preventing the particles from being blocked during discharge and improving the discharge efficiency of the particles. When dehydrating the particles, the shielding plug 4 can be moved downward to close the discharge channel 21, and the dehydration inner tank 2 can be driven by the driving device to rotate at a high speed, so that the moisture on the surface of the particles is thrown out under the centrifugal action to complete the dehydration of the particles. Therefore, the shielding plug 4 is driven by the cylinder 3 to move in the vertical direction, so that the discharge channel 21 can be opened and closed, making the switching between dehydration and discharge of the overall equipment faster and more convenient.

[0019] In the present embodiment, the dehydration liner 2 is located on the side facing the discharge port 102, and the inner diameter decreases gradually along the direction toward the discharge port 102 to form a shielding end 22. Therefore, by moving the shielding plug 4 upward, the inner diameter of the discharge channel 21 on the side facing the shielding end 22 increases gradually, so that a gap can be generated between the shielding plug 4 and the shielding end 22, so that the discharge channel 21 can be opened. With such a design, the shielding plug 4 only needs a distance from one end to open the discharge channel 21, and there is no need to completely detach from the discharge channel 21, thereby improving the efficiency of the shielding plug 4 in opening and closing the discharge channel 21.

[0020] In the present embodiment, a material guiding side wall 41 whose inner diameter gradually decreases along the direction away from the material outlet 102 is provided on the side of the shielding plug 4 which is located away from the material outlet 102. When the shielding plug 4 moves upward to open the material discharge channel 21, the material guiding side wall 41 is provided so that the particles accumulated on the shielding plug 4 can slide down from the material guiding side wall 41 under the action of gravity, thereby preventing the particles from accumulating on the shielding plug 4 after the shielding plug 4 opens the material discharge channel 21.

[0021] In this embodiment, the specific structure of the driving device includes a gear ring 51 fixedly mounted on the outer periphery of the dehydration liner 2, a driving shaft 52 is rotatably connected to the top of the cylinder 1, a transmission gear 53 is fixedly mounted on the outer periphery of the driving shaft 52, the transmission gear 53 is meshed with the gear ring 51, and a motor 54 is connected to the driving shaft 52. The motor 54 is used to drive the transmission gear 53 to rotate, so as to drive the dehydration liner 2 to rotate. By driving the driving shaft 52 to rotate through the motor 54, the rotating transmission gear 53 can drive the dehydration liner 2 to rotate through the gear ring 51 meshed with the transmission gear 53, so that the particles in the dehydration liner 2 can remove the surface moisture under the action of centrifugation;

[0022] In addition, an annular guide rail 6 is further mounted and fixed on the outer periphery of one end of the dehydration inner liner 2 located near the discharge port 102, and a guide wheel 7 is connected to rotate in the vertical direction in the cavity 101. There are multiple guide wheels 7 which are evenly distributed on the outer periphery of the annular guide rail 6 in a circle. The guide wheels 7 are coupled to the annular guide rail 6 and can form a guiding cooperation with each other. During the rotation of the dehydration inner liner 2, the guide wheel 7 can slide along the annular guide rail 6, thereby guiding the rotation of the dehydration inner liner 2, making the rotation of the dehydration inner liner 2 more stable.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
