Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited to the following examples.
[0023] As shown in the figure, the popping bead drum screen of this utility model includes a bar drum and a mesh drum, wherein the outlet end of the bar drum is connected to the inlet end of the mesh drum to form a complete drum, and spiral blades connected to the inner wall of the drum are provided inside the drum for conveying popping beads.
[0024] The perforated roller can be divided into a discharge port roller section and a large particle port roller section. The discharge port roller section is located near the bar roller, while the large particle port roller section is located away from the bar roller. A non-perforated section is provided on the perforated roller between the discharge port roller section and the large particle port roller section. The discharge port roller section has multiple mesh openings matching the size of the burst beads, while the large particle port roller section has multiple mesh openings larger than the size of the burst beads. A burst bead discharge hopper is located below the discharge port roller section to collect qualified burst beads. A large particle collection hopper is located below the large particle port roller section to collect burst beads that are too large. A waste collection hopper is located at the outlet of the large particle port roller section to collect burst beads that are too large or stuck together.
[0025] The bar roller includes a cylinder wall composed of multiple bars spaced apart along the axial direction and multiple fixing rings located around the outer perimeter of the cylinder wall to fix the bars. The spacing between two adjacent bars in the bar roller is smaller than the size of the bursting beads, and a water tank is provided below the bar roller.
[0026] Two rotating shafts are respectively installed along the axial direction at the lower left and lower right of the bar drum. The two rotating shafts are the driving shaft and the driven shaft, respectively. Several transmission rings are fixedly connected to the rotating shafts, and the transmission rings are connected to the fixed rings to support the entire drum.
[0027] A ring-shaped gear disk is provided at the inlet end of the bar drum, and a gear meshing with the ring-shaped gear disk is provided on a rotating shaft (i.e., the drive shaft) to drive the entire drum to rotate. A rotating shaft fixing seat is provided on the water tank, and the rotating shaft is connected to the rotating shaft fixing seat through bearings. In one specific embodiment, there are four rotating shaft fixing seats, located at both ends of the rotating shaft. The drive shaft can be directly connected to the drive motor, or connected to the drive motor through a transmission mechanism.
[0028] This popping bead drum screen also includes an internal water spray pipe, one end of which extends from the inlet end of the bar drum into the interior of the bar drum. One or more internal nozzles are provided on the internal water spray pipe inside the bar drum.

[0030] In operation, the formed burst beads are first introduced into the drum screen through the inlet of the bar drum. Driven by gears and a ring gear disc, the drum screen rotates in the same direction as the spiral blades. The burst beads move from the inlet of the bar drum towards the outlet of the mesh drum, driven by the spiral blades. Simultaneously, the inner and outer water spray pipes are activated to clean the burst beads, and smaller beads fall into the water tank. The burst beads are then carried by the spiral blades to the discharge drum section. Beads meeting quality standards fall directly into the burst bead discharge hopper through the mesh of the discharge drum section. Other burst beads continue to be carried by the spiral blades to the large particle drum section. Oversized beads fall into the large particle collection hopper through the mesh of the large particle drum section, while even larger particles fall into the waste collection hopper from the outlet of the mesh drum, completing the cleaning, solid-liquid separation, and screening operations.
