Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule production equipment, and in particular to a plastic granule centrifugal dewatering machine. Background Technology

[0002] Centrifugal dehydration is a crucial step in the production and processing of plastic granules. Its purpose is to remove moisture adhering to the surface of the plastic granules to meet the requirements of subsequent production or storage. Currently, widely used centrifugal dehydrators for plastic granules typically include a frame, an outer drum, a rotating shaft mounted at the center of the bottom wall of the outer drum, a dehydration filter connected to the upper end of the shaft and located inside the outer drum, and a power unit. During operation, the plastic granules to be dehydrated are placed in the dehydration filter. The power unit drives the shaft to rotate, causing the dehydration filter to rotate at high speed. Centrifugal force is used to throw the water out of the plastic granules, which is then discharged through the drain pipe at the bottom of the outer drum, thus achieving the dehydration operation.

[0003] However, existing technologies have significant drawbacks in practical applications: when the number of plastic granules to be dehydrated is large, the granules tend to accumulate in the dehydration filter, forming large aggregates. This accumulation makes it difficult for the internal plastic granules to fully contact the centrifugal force field, preventing effective water removal and severely impacting the dehydration effect. This results in dehydrated plastic granules with a high moisture content, failing to meet production requirements. Furthermore, to ensure dehydration efficiency, operators may need to reduce the processing volume per cycle, which reduces production efficiency and increases costs. Therefore, solving the problem of plastic granule accumulation affecting dehydration efficiency during the dehydration process has become a pressing technical challenge for those skilled in the art. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a centrifugal dewatering machine for plastic granules.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A centrifugal dewatering machine for plastic granules includes a frame, an outer barrel fixedly mounted on the frame, a rotating shaft rotatably mounted at the center of the bottom wall of the outer barrel, a dewatering filter barrel connected to the upper end of the rotating shaft inside the outer barrel, a power unit connected to the lower end of the rotating shaft inside the frame, a drain pipe provided on one side of the lower end of the outer barrel, a dewatering filter bag detachably placed inside the dewatering filter barrel, a top rod moving vertically through the rotating shaft, a transverse top plate provided at the upper end of the top rod inside the dewatering filter barrel, and a driving device provided on the frame for driving the top rod to move vertically through.

[0007] In some embodiments, a plurality of clamps are provided along the circumference of the outer wall of the dewatering filter barrel, the clamps being used to clamp the opening of the dewatering filter cloth bag.

[0008] In some embodiments, the shaft has a through hole running vertically through its axis, and the inner wall of the through hole is provided with a vertical guide groove. The push rod moves vertically through the through hole, and a guide flange that slides in the vertical guide groove is provided on one side.

[0009] In some embodiments, the driving device includes a support plate disposed within the frame, vertical plates spaced apart on the support plate, a top rod disposed between two of the vertical plates, and vertical grooves provided on the two vertical plates. A rocker is hinged within the frame, one end of the rocker extending out of the front side of the frame and provided with a foot pedal, and the other end of the rocker being provided with a transverse groove. A rotating sleeve is rotatably fitted on the top rod, and guide posts are respectively provided on both sides of the rotating sleeve, with the guide posts on both sides respectively located within the vertical groove and the transverse groove.

[0010] In some embodiments, a tension spring is connected between the bottom end of the top rod and the support plate.

[0011] In some embodiments, the power unit includes a motor disposed within the frame, a first pulley disposed on the output shaft of the motor, a second pulley disposed on the rotating shaft, and a belt sleeved between the first pulley and the second pulley.

[0012] In some embodiments, a lid is movably closed over the opening of the outer barrel.

[0013] In some embodiments, a support foot is provided at the lower end of the frame.

[0014] In some embodiments, four transverse top plates are evenly distributed along the circumference.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. First, a dewatering filter bag is detachably placed inside the dewatering filter bucket. Plastic granules are poured into the dewatering filter bag, so that the dewatering filter bag can be directly removed after the dewatering process is completed, thus improving efficiency.

[0017] 2. In addition, by installing a top rod that moves up and down through the rotating shaft, and setting a transverse top plate at the upper end of the top rod, when the drive device drives the top rod to move up and down, the transverse top plate can push the dewatering filter bag placed in the dewatering filter barrel upwards. This action can effectively disperse the plastic particles that are piled up together, making the originally agglomerated particles disperse and increasing the gap between the particles. In this way, each plastic particle can be more fully exposed in the centrifugal force field, and the water can be thrown out more smoothly through the filter holes of the dewatering filter bag and the dewatering filter barrel, which significantly improves the efficiency and effect of dewatering, ensuring that the dewatered plastic particles have a lower moisture content and meet production requirements.

[0018] 3. Because this structure can effectively solve the problem of plastic particle accumulation affecting the dehydration effect, more plastic particles can be processed in the same dehydration time without having to reduce the processing volume each time due to concerns about accumulation. This not only improves the utilization rate of the equipment, but also reduces the number of dehydration operations, thereby significantly improving the overall production efficiency and reducing production costs.

[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] like Figures 1-6The centrifugal dewatering machine for plastic granules shown includes a frame 1, an outer barrel 2 fixedly mounted on the frame 1, a rotating shaft 3 rotatably mounted at the center of the bottom wall of the outer barrel 2, a dewatering filter barrel 4 connected to the upper end of the rotating shaft 3 inside the outer barrel 2, a power device connected to the lower end of the rotating shaft 3 inside the frame 1, a drain pipe 7 provided on one side of the lower end of the outer barrel 2, a dewatering filter bag detachably placed inside the dewatering filter barrel 4, a top rod 5 moving vertically through the rotating shaft 3, a transverse top plate 6 provided at the upper end of the top rod 5 inside the dewatering filter barrel 4, four transverse top plates 6 evenly distributed along the circumference, and a driving device for driving the top rod 5 moving vertically through the frame 1.

[0027] Based on the above structure, a dewatering filter bag (not shown in the attached diagram) is detachably placed inside the dewatering filter bucket 4. Plastic granules are poured into the dewatering filter bag, so that the dewatering filter bag can be directly removed after the dewatering process is completed, thus improving efficiency.

[0028] In addition, by moving the top rod 5 through the rotating shaft 3 up and down, and setting the transverse top plate 6 at the upper end of the top rod 5, when the driving device drives the top rod 5 to move up and down, the transverse top plate 6 can push the dewatering filter bag placed in the dewatering filter barrel 4 upward. This action can effectively disperse the plastic particles that are piled up together, making the originally agglomerated particles disperse and increasing the gap between the particles. In this way, each plastic particle can be more fully exposed in the centrifugal force field, and the water can be thrown out more smoothly through the filter holes of the dewatering filter bag and the dewatering filter barrel 4, which significantly improves the efficiency and effect of dewatering, ensuring that the dewatered plastic particles have a lower moisture content and meet production requirements.

[0029] Because this structure effectively solves the problem of plastic particle accumulation affecting dehydration, more plastic particles can be processed in the same dehydration time without having to reduce the processing volume each time due to concerns about accumulation. This not only improves the utilization rate of the equipment but also reduces the number of dehydration operations, thereby significantly improving overall production efficiency and reducing production costs.

[0030] See Figure 2 As shown in Figure 5, several clips 21 are arranged along the circumference of the outer wall of the dewatering filter barrel 4. The clips 21 are used to clamp the opening of the dewatering filter bag. After the dewatering filter bag is placed into the dewatering filter barrel 4, the opening of the filter bag is opened and the clips 21 are used to clamp and fix the opening along the circumference of the outer wall of the dewatering filter barrel 4, so that the filter bag is stably installed in the dewatering filter barrel 4, and then the subsequent plastic granule loading and centrifugal dewatering operations are carried out.

[0031] See Figures 4 to 6As shown, the shaft 3 has a through hole 31 running vertically through its axis. The inner wall of the through hole 31 is provided with a vertical guide groove 32. The top rod 5 moves vertically through the through hole 31 and has a guide flange 33 that slides in the vertical guide groove 32 on one side.

[0032] The through hole 31 at the center of the rotating shaft 3 provides a moving channel for the push rod 5. The vertical guide groove 32 on the inner wall cooperates with the guide flange 33 of the push rod 5 to restrict the direction of movement of the push rod 5, so that the push rod 5 can only move vertically up and down, ensuring the stability and accuracy of the movement of the push rod 5. This allows the push rod 5 to rotate with the rotating shaft 3, thereby ensuring that the horizontal top plate 6 can accurately push the plastic particles.

[0033] See Figures 2-6 As shown, the driving device includes a support plate 41 disposed within the frame 1, vertical plates 42 spaced apart on the support plate 41, a top rod 5 disposed between the two vertical plates 42, and the two vertical plates 42 being provided with vertical grooves 43. A rocker 44 is hinged within the frame 1, one end of the rocker 44 extending out of the front side of the frame 1 and being provided with a foot pedal 45, and the other end of the rocker 44 being provided with a transverse groove 46. A rotating sleeve 47 is rotatably fitted onto the top rod 5, and guide posts 48 are respectively provided on both sides of the rotating sleeve 47, with the guide posts 48 on both sides respectively disposed within the vertical grooves 43 and the transverse grooves 46.

[0034] The push rod 5 moves up and down by manually stepping on the foot pedal 45, using the lever principle. The structure is simple, easy to operate, and low in cost. It also allows the operator to flexibly control the movement of the push rod 5 according to the actual dehydration situation. The vertical slide 43 and the horizontal slide 46 cooperate with the guide column 48 to further ensure the accuracy of the movement trajectory of the push rod 5.

[0035] Furthermore, a tension spring 51 is connected between the bottom end of the top rod 5 and the support plate 41; after the foot pedal 45 is released, it can provide a reset pull force, so that the top rod 5 automatically returns to the initial position, which is convenient for the next operation.

[0036] See Figure 2 As shown, the power unit includes a motor 61 installed in the frame 1, a first pulley 62 installed on the output shaft of the motor 61, a second pulley 63 installed on the rotating shaft 3, and a belt 64 connected between the first pulley 62 and the second pulley 63; this can ensure that the rotating shaft 3 and the dewatering filter 4 rotate stably and at high speed, meeting the speed requirements for centrifugal dewatering of plastic particles; at the same time, this transmission method has a simple structure and is easy to install, maintain and replace parts.

[0037] Furthermore, a lid 71 is movably closed at the opening of the outer barrel 2; the lid 71 at the opening of the outer barrel 2 can prevent water and plastic particles from splashing out during centrifugal dehydration, ensuring a clean and safe working environment; at the same time, the lid can reduce noise transmission during dehydration and reduce noise pollution in the workplace.

[0038] Furthermore, a support foot 81 is provided at the lower end of the frame 1; thus, the height of the support foot 81 can be adjusted according to the ground conditions to keep the frame horizontal and stable, ensuring that the equipment is firmly installed before subsequent operations are carried out.

[0039] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.

The scope of protection of this utility model is defined by the appended claims and their equivalents.
