Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a centrifugal dehydrator. Background Art

[0002] Thermoplastic elastomers (TPE / TPR), also known as artificial rubber or synthetic rubber, combine the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, with the ease and versatility of processing common plastics.

[0003] During the production process of thermoplastic elastomer, it is necessary to dehydrate the thermoplastic elastomer cooled with water. The existing technology is to dehydrate it by a centrifugal dehydrator, such as a new type of centrifugal dehydrator disclosed in Publication No. (CN215113811U), which includes a base, a housing is fixed on the top of the base by bolts, a feeding mechanism is provided on one side of the housing, a driving motor is fixed on the bottom of the base by bolts, the output shaft of the driving motor is fixedly sleeved with a main pulley, a filter is provided on the housing, the internal rotation of the filter is connected to a rotating roller, and the bottom of the rotating roller is welded with a The rotating shaft, the outer wall of the rotating shaft is sleeved with a slave pulley, the outside of the main pulley and the slave pulley is sleeved with a transmission belt, the outer wall of the rotating roller is welded with a number of baffles in an equidistant ring, the outer wall of the rotating roller is welded with a number of feeding plates in an equidistant ring, and one end of the feeding plate is welded to one side of the baffle. The above technical solution feeds the material through the rotating roller, and the baffle can collide with the transported plastic particles to separate the water. Due to the limited stroke of the rotating roller, when many thermoplastic elastomers are gathered together, the separation effect is poor. However, for this reason, we propose a centrifugal dehydrator. Utility Model Content

[0004] The utility model addresses the deficiencies in the prior art and provides a centrifugal dehydrator. A thermoplastic elastomer is placed in an inner cylinder, and the rotation of a rotating frame drives the thermoplastic elastomer to rotate centrifugally in the inner cylinder, thereby throwing water out from the water seepage holes. A fixed plate in the rotating frame continuously turns the thermoplastic elastomer to prevent adhesion between the thermoplastic elastomers and ensure the dehydration effect.

[0005] In order to solve the above technical problems, the present invention solves the problem of poor dehydration effect of thermoplastic elastomers when they are dehydrated by rotating rollers through the following technical solutions.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A centrifugal dehydrator comprises a support frame, an outer cylinder is fixedly provided in the support frame, an inner cylinder is fixedly provided in the outer cylinder, a rotating frame is rotatably provided in the inner cylinder, evenly distributed fixed plates are fixedly provided in the rotating frame, a feed pipe and a discharge pipe are fixedly provided in the outer cylinder and the inner cylinder, valves are fixedly provided on the feed pipe and the discharge pipe, the feed pipe is provided at the top of the outer cylinder, the discharge pipe is provided at the bottom of the outer cylinder, a motor is fixedly provided on the outside of the support frame, the output end of the motor is fixed to the axis of the rotating frame, a water outlet pipe connected to the inside of the outer cylinder is fixedly provided on the outside of the bottom of the outer cylinder, evenly distributed water seepage holes are provided on the inside of the inner cylinder, and an auxiliary component for blowing air to the material in the inner cylinder is provided in the outer cylinder.

[0008] Preferably, the outer side of the fixing plate fits in with the inner side of the inner cylinder. When the rotating frame rotates, the fixing plate always scrapes the inner side of the inner cylinder to prevent the thermoplastic elastomer from adhering to the inner wall of the inner cylinder.

[0009] Preferably, the fixed plate coincides with the radial direction of the rotating frame.

[0010] Preferably, the end of the water outlet pipe away from the outer cylinder is a curved pipe with the outlet facing downward.

[0011] Preferably, the auxiliary component includes a spacer ring, which is fixed between the outer cylinder and the inner cylinder. The spacer ring is arranged on the side of the inner cylinder away from the motor. Air inlet holes are evenly arranged in the spacer ring. The air inlet holes are arranged on the outside of the inner cylinder. External air can be sucked into the inner cylinder through the air inlet holes and then discharged from the water seepage holes. The air flows from the middle of the inner cylinder to the water seepage holes, blowing on the surface of the thermoplastic elastomer, thereby increasing the evaporation of moisture on the surface of the thermoplastic elastomer and improving the dehydration effect.

[0012] Preferably, the spacer ring is coaxial with the inner cylinder to ensure that air enters the inner cylinder from the center of the inner cylinder.

[0013] Preferably, an exhaust pipe is fixedly provided on the outside of the outer cylinder, and the exhaust pipe is connected to the inside of the outer cylinder to improve the exhaust efficiency of the gas in the device.

[0014] Preferably, the exhaust pipe is a right-angle elbow, and the exhaust pipe outlet is vertically upward to prevent water droplets thrown out from the water seepage hole from splashing out of the exhaust pipe.

[0015] Preferably, a mesh plate is fixedly provided at the exhaust pipe outlet to prevent external debris from falling into the exhaust pipe.

[0016] Preferably, the inner bottom of the water outlet pipe fits into the inner bottom of the outer cylinder to ensure that all the water in the outer cylinder can be discharged through the water outlet pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model places the thermoplastic elastomer in the inner cylinder, and drives the fixed plate to move by the rotation of the rotating frame, thereby driving the thermoplastic elastomer to move centrifugally in the inner cylinder. The water attached to the thermoplastic elastomer is discharged through the water seepage holes under the action of centrifugation, and the dehydration effect is good.

[0019] By setting an air inlet hole connecting the inner cylinder with the outside world at the center of the outer side of the inner cylinder, when the fixed plate rotates, a vortex is generated at the center of the inner cylinder, and the external air is sucked into the inner cylinder through the air inlet hole. The flowing air is then discharged through the water seepage hole. In this process, the flowing air blows on the surface of the thermoplastic elastomer, accelerating the evaporation of water on the surface of the thermoplastic elastomer, thereby improving the dehydration effect.

[0028] The present invention is described in further detail below with reference to the accompanying drawings.

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0032] See also Figures 1-6 A centrifugal dehydrator includes a support frame 1, an outer cylinder 2 is fixedly provided in the support frame 1, an inner cylinder 3 is fixedly provided in the outer cylinder 2, a rotating frame 4 is rotatably provided in the inner cylinder 3, and a uniformly distributed fixed plate 5 is fixed in the rotating frame 4. A feed pipe 6 and a discharge pipe 7 are fixed in the outer cylinder 2 and the inner cylinder 3. Valves are fixed on the feed pipe 6 and the discharge pipe 7. The feed pipe 6 is arranged at the top of the outer cylinder 2, and the discharge pipe 7 is arranged at the bottom of the outer cylinder 2. A motor 8 is fixed on the outside of the support frame 1, and the output end of the motor 8 is fixed to the axis of the rotating frame 4. A water outlet pipe 9 communicating with the inside of the outer cylinder 2 is fixed on the outside of the bottom of the outer cylinder 2. Evenly distributed water seepage holes 10 are provided on the inside of the inner cylinder 3, and an auxiliary component 11 for blowing air to the material in the inner cylinder 3 is provided in the outer cylinder 2.

[0033] In an embodiment of the present application, the auxiliary component 11 includes a spacer ring 12, which is fixed between the outer cylinder 2 and the inner cylinder 3. The spacer ring 12 is arranged on the side of the inner cylinder 3 away from the motor 8. Air inlet holes 13 are evenly arranged in the spacer ring 12. The air inlet holes 13 are arranged on the outside of the inner cylinder 3. External air can be sucked into the inner cylinder 3 through the air inlet holes 13 and then discharged from the water seepage holes 10. The air flows from the middle of the inner cylinder 3 to the water seepage holes 10, blowing on the surface of the thermoplastic elastomer, thereby increasing the evaporation of moisture on the surface of the thermoplastic elastomer and improving the dehydration effect.

[0034] During the implementation process, the thermoplastic elastomer enters the inner cylinder 3 through the feed pipe 6, and then the rotating frame 4 is driven to rotate by the motor 8, and the rotating frame 4 drives the fixed plate 5 to move on the inner wall of the inner cylinder 3. Since the outer side of the fixed plate 5 is in contact with the inner side of the inner cylinder 3, when the rotating frame 4 rotates, the fixed plate 5 is always in contact with the inner wall of the inner cylinder 3, preventing the thermoplastic elastomer from adhering to the inner wall of the inner cylinder 3. Driven by the fixed plate 5, the thermoplastic elastomer performs centrifugal motion in the inner cylinder 3, and the water on the surface of the thermoplastic elastomer is thrown out from the water seepage hole 10. The thrown water falls in the outer cylinder 2 and is finally discharged from the outlet pipe 9 whose inner bottom is cut with the inner bottom of the outer cylinder 2. The outer outlet faces downward, and water can be collected using a bucket or the like to prevent water from being sprayed into the external environment when discharged from the water outlet pipe 9. In the process of the rotating frame 4 driving the fixed plate 5 to rotate, a vortex is generated at the center of the inner cylinder 3, and the external air is sucked into the inner cylinder 3 through the air inlet 13 arranged inside the spacer ring 12 coaxial with the inner cylinder 3. The inhaled air is then discharged through the water seepage hole 10 and finally discharged through the exhaust pipe 14 arranged on the outside of the outer cylinder 2. During the flow of air in the inner cylinder 3, it blows on the surface of the thermoplastic elastomer in the inner cylinder 3, and the moisture on the surface of the thermoplastic elastomer evaporates, and the water vapor is taken away with the flowing air, thereby improving the dehydration effect of the thermoplastic elastomer.

[0035] like Figure 6 As shown, the exhaust pipe 14 is set as a right-angle bend pipe with the outlet facing upward, which can prevent water thrown out from the seepage hole 10 from splashing out of the exhaust pipe 14 to the outside. At the same time, the mesh plate 15 set at the outlet of the exhaust pipe 14 can prevent debris in the external environment from falling into the exhaust pipe 14.

[0036] like Figure 5 and Figure 6 As shown, by arranging the fixed plate 5 in the radial direction of the rotating frame 4, the disordered flow of the material can be restricted, and the material can flow along a certain path or direction, thereby stabilizing the flow state of the material; at the same time, the fixed plate 5 can play a certain buffering role. When the material rotates in the inner cylinder 3, the fixed plate 5 can reduce the direct contact and friction between the material and the inner wall of the inner cylinder 3, thereby reducing the degree of wear of the material.

[0037] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles.
