Description

Technical Field

[0001] This application relates to the technical field of physical dehydration devices, and in particular to a lightweight foam plastic particle dehydration device. Background Technology

[0002] Foamed plastic granules are small granular substances made by foaming plastic materials through physical or chemical methods. These granules contain a large number of air bubbles and have properties such as being lightweight, heat-insulating, sound-absorbing, and cushioning.

[0003] Residual moisture affects the density of foamed plastic particles, thus requiring dehydration. Existing dehydration devices use a rotating drum constructed by welding sheet metal into a cylindrical shape. Several blades are welded to the outer circumference of the drum, arranged at an angle. During dehydration, the weight of the welded areas is greater than other areas, resulting in higher centrifugal force and uneven stress on the drum. This can cause damage to the welded areas during rotation, requiring the entire drum and its attached blades to be replaced, leading to material waste. Improvements are needed. Summary of the Invention

[0004] The purpose of this application is to provide a lightweight foam plastic particle dewatering device to reduce material waste.

[0005] This application provides a lightweight foam plastic granule dewatering device with the following technical solution: It includes a body with a cavity. A dewatering net is connected inside the cavity, dividing the cavity into a water outlet chamber and a dewatering chamber. The body is connected to an inlet pipe and an outlet pipe communicating with the dewatering chamber. The body is also connected to an outlet pipe communicating with the water outlet chamber. The device is characterized in that: a rotating shaft is rotatably connected inside the dewatering chamber; a drive assembly for driving the rotating shaft is connected to the body; several connecting pieces are detachably connected to the outer circumference of the rotating shaft; each connecting piece has several blades inclinedly arranged on its side away from the rotating shaft; the distance between the blades and the dewatering net is smaller than the diameter of the foam plastic granules; and the blades are used to move the foam plastic granules at the inlet pipe to the outlet pipe.

[0006] By adopting the above technical solution, foamed plastic granules move to the dewatering chamber through the feeding pipe. The drive assembly drives the rotating shaft to rotate around its own axis, meaning all connecting plates and blades rotate around the axis of the rotating shaft. During the rotation, the blades drive the foamed plastic granules at the bottom of the dewatering chamber towards the discharge pipe. Centrifugal force is used to throw out the water from the foamed plastic granules. The water passes through the dewatering screen and is discharged from the discharge pipe. The dewatered foamed plastic granules are then discharged from the discharge pipe, thus achieving dewatering of the foamed plastic granules. The connecting plates on the outer circumference of the rotating shaft are detachable, avoiding the need to replace the entire rotating drum and blades due to partial damage, and reducing material waste.

[0007] Optionally, the rotating shaft is connected to a connecting block, and each connecting piece is connected to the connecting block by a locking member.

[0008] By adopting the above technical solution, the connecting piece can be connected to the connecting block through the locking element, realizing the detachable connection between the connecting piece and the rotating shaft, avoiding the need to replace the entire component due to partial damage, reducing material waste, and facilitating the replacement and maintenance of the connecting piece.

[0009] Optionally, a plurality of the connecting blocks are connected to the rotating shaft, all of the connecting blocks are distributed along the length direction of the rotating shaft, and the distance between two adjacent connecting blocks is equal.

[0010] By adopting the above technical solution, the force on each part of the connecting plate is more uniform during dehydration, reducing component damage caused by uneven force, and individual connecting plates and blades can be easily replaced, avoiding material waste.

[0011] Optionally, each of the connecting blocks is provided with a plurality of mounting surfaces, each mounting surface corresponding to a connecting piece, the connecting piece being connected to the mounting surface, and each of the connecting blocks being provided with a plurality of arc grooves, with one arc groove between two adjacent mounting surfaces.

[0012] By adopting the above technical solution, the arc groove can reduce the overall weight of the connecting block and facilitate the rotation of the connecting block, connecting piece and blade.

[0013] Optionally, the connecting piece includes a connecting plate and a bent plate disposed on the connecting plate, the connecting plate being connected to the mounting surface, and the blade being disposed on the side of the connecting plate away from the mounting surface.

[0014] By adopting the above technical solution, the cooperation between the bending plate and the connecting plate increases the overall rigidity of the connecting piece, making it less prone to deformation.

[0015] Optionally, the blade extends toward the bending plate, the distance between the bending plate and the dewatering net is less than the diameter of the foam plastic particles, the blade is used to guide the foam plastic particles to move toward the bending plate, and the bending plate is used to guide the foam plastic particles to move toward the dewatering net.

[0016] By adopting the above technical solution, when the bending plate rotates around the axis of rotation, it guides the foam plastic particles to move towards the bending plate. The foam plastic particles come into contact with the bending plate, and the bending plate guides the foam plastic particles to move towards the dewatering screen. Since the diameter of the foam plastic particles is smaller than the distance between the bending plate and the dewatering screen, the bending plate restricts the foam plastic particles from passing through the gap between the bending plate and the dewatering screen. This allows the foam plastic particles to move towards the discharge pipe along the length of the bending plate and rotate around the axis of rotation, thus achieving both dewatering and movement of the foam plastic particles.

[0017] Optionally, the dewatering net includes a fixed net and a movable net detachably connected to the fixed net. The discharge end of the feed pipe and the feed end of the discharge pipe are both connected to the fixed net. Several fixing structures are connected between the fixed net and the movable net. The fixing structures are used to fix or loosen the fixed net and the movable net.

[0018] By adopting the above technical solution, a fixed structure is used to fix or loosen the fixed net and the moving net, which facilitates the disassembly and installation of the dewatering net. When the blades or connecting pieces are damaged, the fixed structure loosens the moving net, exposing the blades and connecting pieces, so that the connecting pieces can be replaced.

[0019] Optionally, the fixing structure includes a fixing rod hinged to the fixing net and a screw block threaded to the fixing rod. The movable net is provided with a mounting part, and the mounting part is provided with a mounting groove for the fixing rod to be engaged.

[0020] By adopting the above technical solution, when it is necessary to replace the blades and connecting pieces, loosen the screw block to separate it from the mounting part. The fixing rod can then rotate and disengage from the mounting slot, allowing the mobile net to be removed from the fixed net for replacement of the blades and connecting pieces. After replacing the blades and connecting pieces, rotate the fixing rod to re-engage it into the mounting slot. Rotate the screw block until it abuts against the mounting part, clamping the mounting part between the screw block and the fixed net, thus re-fixing the mobile net to the fixed net.

[0021] Optionally, the inner wall of the feed pipe is connected with a number of blocking rods at intervals, and the distance between two adjacent blocking rods is equal to the diameter of the foam plastic particles.

[0022] By adopting the above technical solution, several blocking rods prevent larger foam plastic particles from passing through the blocking rods and falling into the dehydration chamber, thereby achieving separation of foam plastic particles by size.

[0023] Optionally, a connecting pipe is provided between the feed pipe and the outlet pipe, the connecting pipe connecting the feed pipe and the outlet pipe, and a filter screen is provided at the connection between the feed pipe and the connecting pipe.

[0024] By adopting the above technical solution, the foam plastic particles pass through a water filter screen before entering the dewatering chamber. The water filter screen filters the water on the foam plastic particles in advance, reducing the water content in the foam plastic particles and improving the dewatering effect of the foam plastic particles in the later stage.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The outer circumference of the rotating shaft is detachably connected to a connecting piece, which avoids the need to replace the entire rotating drum and blades due to local damage and reduces material waste.

[0027] 2. When the bending plate rotates around the axis of rotation, it guides the foam plastic particles to move closer to the bending plate. The foam plastic particles come into contact with the bending plate, and the bending plate guides the foam plastic particles to move closer to the dewatering screen. Since the diameter of the foam plastic particles is smaller than the distance between the bending plate and the dewatering screen, the bending plate restricts the foam plastic particles from passing through the gap between the bending plate and the dewatering screen. This allows the foam plastic particles to move along the length of the bending plate towards the discharge pipe and rotate around the axis of rotation, thus achieving both dewatering and movement of the foam plastic particles.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1 -Attached Figure 8 This application will be described in further detail.

[0038] This application discloses a lightweight foam plastic particle dehydration device.

[0039] Combination Figure 1 , Figure 2 and Figure 3As shown, the machine includes a body 1, which has a cavity 11. A dewatering net 2 is connected inside the cavity 11. The dewatering net 2 is annular and divides the cavity 11 into an outlet cavity 111 and a dewatering cavity 112. The dewatering net 2 includes a fixed net 21 fixedly connected inside the machine body 1 and a movable net 22 detachably connected to the fixed net 21. The outlet end of the feed pipe 12 and the feed end of the discharge pipe 15 are both fixedly connected to the fixed net 21. Several fixed structures 3 are connected between the fixed net 21 and the movable net 22. The fixed structures 3 are used to fix or loosen the fixed net 21 and the movable net 22. The several fixed structures 3 are distributed at intervals along the height direction of the fixed net 21, and the distance between two adjacent fixed structures 3 is equal. The fixing structure 3 includes a fixing rod 31 hinged to the outer circumference of the fixing net 21 and a screw block 32 threadedly connected to the fixing rod 31. The outer surface of the moving net 22 is fixedly connected to a mounting part 221, which is elongated and distributed along the height of the moving net 22. Each mounting part 221 has several mounting slots 222, each corresponding to a fixing rod 31, allowing the fixing rod 31 to engage with the mounting slot. When disassembling the moving net 22, each screw block 32 is rotated, separating it from the mounting part 221. The fixing rod 31 can then rotate and disengage from the mounting slot, allowing the moving net 22 to move relative to the fixing net 21. When installing the mobile net 22, rotate the fixing rod 31 so that the fixing rod 31 is inserted into the mounting groove 222, rotate the screw block 32 until the screw block 32 abuts against the mounting part 221, the mounting part 221 is clamped by the screw block 32 and the fixed net 21, and the mobile net 22 is fixedly connected to the fixed net 21.

[0040] Combination Figure 4 and Figure 5As shown, a feed pipe 12 communicating with the dehydration chamber 112 is fixedly connected to one side of the machine body 1. The outlet of the feed pipe 12 is located at the bottom of the machine body 1, and the inlet of the feed pipe 12 is higher than the outlet of the feed pipe 12. Several blocking rods 121 are fixedly connected at intervals to the inner wall of the feed pipe 12. The blocking rods 121 are inclined, and the distance between two adjacent blocking rods 121 is equal to the diameter of the foam plastic particles. The blocking rods 121 are located between the inlet and outlet of the feed pipe 12. A door is rotatably connected to one side of the machine body 1. Rotating the door opens the feed pipe 12. The height of the end of the blocking rod 121 away from the door is higher than the height of the end of the blocking rod 121 near the door. The distance between the end of the blocking rod 121 near the door and the door is equal to the diameter of the foam plastic particles. When a large number of large foam plastic particles accumulate on the blocking rod 121, the operator can remove the large foam plastic particles from the blocking rod 121 by rotating the door. The machine body 1 is fixedly connected to a water outlet pipe 13 that communicates with the water outlet chamber 111. The water inlet of the water outlet pipe 13 is located at the bottom of the machine body 1. The outlet of the feed pipe 12 is higher than the inlet of the water outlet pipe 13. A connecting pipe 14 connects the feed pipe 12 and the water outlet pipe 13. A filter screen 141 is fixedly connected at the connection between the feed pipe 12 and the connecting pipe 14. Foam plastic particles enter the feed pipe 12 through the feed inlet of the feed pipe 12. The foam plastic particles fall onto the blocking rod 121 due to gravity. Foam plastic particles of the correct size pass through the gap between two adjacent blocking rods 121 and through the filter screen 141. The filter screen 141 performs preliminary filtration of the water in the feed pipe 12, thereby reducing the amount of water entering the dehydration chamber 112. The machine body 1 is fixedly connected to a discharge pipe 15 that communicates with the dewatering chamber 112, and the inlet of the discharge pipe 15 is located at the top of the machine body 1.

[0041] Combination Figure 4 and Figure 5 As shown, a rotating shaft 4 is rotatably connected inside the dehydration chamber 112, and the dehydration net 2 is wrapped around the rotating shaft 4. The machine body 1 is connected to a drive assembly, which drives the rotating shaft 4 to rotate around its own axis. The drive assembly includes a motor, a belt, and two pulleys. The motor is fixedly connected to the machine body 1, one pulley is fixedly connected to the output end of the motor, and the other pulley is fixedly connected to one end of the rotating shaft 4. The belt is sleeved on the two pulleys, and the motor drives the corresponding pulley to rotate. The pulley drives the rotating shaft 4 to rotate around its own axis through the belt and the other pulley.

[0042] Combination Figure 6 , Figure 7 and Figure 8As shown, a plurality of connecting blocks 5 are connected to the outer circumferential surface of the rotating shaft 4. The distance between two adjacent connecting blocks 5 is equal, and the connecting blocks 5 and the rotating shaft 4 can be connected by bolts. The outer surface of the connecting blocks 5 has a plurality of mounting surfaces 51 and a plurality of arc grooves 52. Taking this embodiment as an example, the number of mounting surfaces 51 and the number of arc grooves 52 are both six, and there is one arc groove 52 between two adjacent mounting surfaces 51. Each mounting surface 51 is connected to a connecting piece 6. The connecting piece 6 includes a connecting plate 61 and a bent plate 62 disposed on the connecting plate 61. The bent plate 62 is inclined relative to the connecting plate 61. The connecting plate 61 and the mounting surface 51 are connected by a locking member, which is a bolt. A plurality of blades 7 are welded to the side of each connecting plate 61 away from the connecting block 5. The blades 7 are distributed at intervals along the height direction of the connecting plate 61, and the distance between two adjacent blades 7 is equal. The blade 7 is inclined, facing the bending plate 62. The end of the blade 7 near the bending plate 62 is higher than the end of the blade 7 away from the bending plate 62. The side of the blade 7 away from the connecting plate 61 is an outward arc shape. The distance between the blade 7 and the dewatering net 2, and the distance between the bending plate 62 and the dewatering net 2, are smaller than the diameter of the foam plastic particles. When the rotating shaft 4 rotates, the connecting block 5, the connecting plate 61, the bending plate 62, and the blade 7 all rotate around the axis of the rotating shaft 4. During the rotation, the blade 7 drives the foam plastic particles at the bottom of the machine body 1 to move towards the discharge pipe 15. The blade 7 guides the foam plastic particles to move towards the bending plate 62, so that the foam plastic particles move along the length of the bending plate 62 towards the discharge pipe 15 and rotate around the axis of the rotating shaft 4. This achieves both dewatering and movement of the foam plastic particles.

[0043] The implementation principle of the lightweight foam plastic granule dewatering device in this application embodiment is as follows:

[0044] When blade 7 or connecting piece 6 is damaged, disassemble the moving net 22, then remove the damaged connecting piece 6 using the locking mechanism, and then replace it with a new connecting piece 6 using the locking mechanism. This avoids replacing the entire rotating drum and blade 7 due to partial damage, thus reducing material waste.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
