Description

Technical Field

[0001] The present application relates to the technical field of pelletizer material collection, and in particular to an underwater pelletizer material collection device. Background Art

[0002] The receiving device of the underwater pelletizer is a key part for collecting and processing plastic particles in the underwater pelletizing process. In the plastic extrusion production process, the molten plastic is extruded through the die head, immediately cooled by the cooling water flow and cut into particles. In the pelletizing process, if the cutter is worn out during long-term use, or the blade is not sharp enough, the die head hole is blocked, the cooling is insufficient, the cutting speed is not matched, or the relevant process parameters are improperly set, etc., the size of the particles will be inconsistent. Some particles become larger and cannot meet the factory requirements. Therefore, in the process of collecting materials, these large-size particles usually need to be filtered; the existing filtering method is to use an inclined filter screen for filtering large-size particles. The water flow carries the pellets to the filter screen first, and the small-size particles are dried after passing through the filter screen, and the large-size particles roll down the filter screen and are discharged.

[0003] However, such a design will have the following problems. First, when the particles carried by the water flow pass through the filter, they roll down quickly due to gravity, resulting in insufficient time for large and small particles to separate. When the water flow is too fast, the impact force of the water flow may prevent small particles from passing through the filter smoothly. Instead, they will be carried to the path of large particles and eventually discharged together with the large particles. In addition, there will be accumulation of impurities, blockage or roughness on the surface of the filter, and particles may not pass through smoothly. Impurities or adhesions will prevent small particles from passing through the mesh, causing them to be blocked and discharged together with large particles. Summary of the invention

The two first filter housings 1 are commonly installed with a vibration assembly 2, and the vibration assembly 2 is located between the two first filter housings 1. The vibration assembly 2 is connected to the large particle filter screen 14; A control component 3 is installed in the installation housing 13, and a shovel 31 is connected to the control component 3. The two first filter housings 1 are commonly connected to a first discharge pipe 15 for discharging small-size particles and water. The first discharge pipe 15 is located at the bottom of the first filter housing 1. A second discharge pipe 16 is connected to the side of the first filter housing 1 away from the installation housing 13. The control component 3 is used to control the shovel 31 to extend into the first filter housing 1 and shovel large-size particles to the second discharge pipe 16. The first discharge pipe 15 is connected to the drying filter assembly 4, the drying filter assembly 4 is also connected to the scum filter assembly 5, the scum filter assembly 5 is connected to the cooling assembly 6, the drying filter assembly 4 is located on one side of the first filter shell 1, and the scum filter assembly 5 is located below the first filter shell 1.

[0035] After the cutting system cuts the extruded material into particles in the water, the particles and water flow are discharged to the feed pipe 17 together and then discharged into the first filter housing 1. The vibration component 2 drives the large particle filter 14 to vibrate to ensure that the large particles will not gather and block the filter holes, thereby keeping the small particles and water able to pass through the large particle filter 14 smoothly. After a period of use, the control component 3 drives the shovel 31 to shovel the particles on the large particle filter 14 to the second discharge pipe 16 for discharge, and the small particles and water are discharged to the drying filter component 4 for separation of small particles and water. The small particles can be shipped after drying. The water is then discharged to the scum filter component 5 for filtration, and then flows to the cooling component 6 for cooling, and finally flows back to the cutting system for use, thereby effectively filtering large-size particles and reducing the mixed discharge of small-size particles and large-size particles.

[0036] Furthermore, when a first filter housing 1 is filtering, the solenoid valve 12 corresponding to another first filter housing 1 is started, so that particles and water can only flow through one first filter housing 1 for filtering. When the control component 3 of a first filter housing 1 drives the shovel 31 to work, the solenoid valve 12 corresponding to the first filter housing 1 is started to avoid accidentally shoveling small particles together. At the same time, the solenoid valve 12 corresponding to the other first filter housing 1 is closed, so that water and particles flow through the other first filter housing 1 for filtering, ensuring that the filtering and cleaning of large particles can continue to operate and avoiding the need to shut down.

[0037] like Figure 3 The control assembly 3 includes a slide rail 32, on which a moving frame 38 is slidably arranged. The moving frame 38 is driven by a servo drive unit 33. The servo drive unit 33 includes a drive motor and a lead screw. The drive motor is mounted on the mounting housing 13, and the lead screw is rotatably arranged on the upper track.

[0040] The second motor 27 electrically rotates the rotating shaft 25, so that the rotating shaft 25 drives the rotation of the semi-circular disk 26. The semi-circular disk 26 is equivalent to an eccentric wheel, so that the vibration plate 23 will reciprocate. The vibration plate 23 drives the connecting column 22 to move, so that the connecting column 22 drives the large particle filter 14 to reciprocate, and cooperates with the spring 24 to reduce the reciprocating travel of the vibration plate 23, thereby achieving the effect of driving the large particle filter 14 to vibrate, and can simultaneously drive the large particle filter 14 of the two first filter housings 1 to vibrate.
