[0024] Beneficial Effects

[0025] The present invention provides a processing device and process for a HDPE double-wall corrugated pipe. Compared with the prior art, it has the following beneficial effects:

[0026] 1. A processing device and process for a HDPE double-wall corrugated pipe. Through the cooperation between an upper mixing rod mechanism, a lower mixing rod mechanism, a screening mechanism and a liquid pumping mechanism, not only can the powdered raw materials and liquid raw materials be pre-mixed, but also each powdered raw material can be quickly screened in advance, and large-particle raw materials that do not meet the processing standards can be filtered out. With the rotation of the lower mixing rod mechanism, the liquid pumping mechanism can be automatically driven to work, and the external liquid raw materials can be intermittently sucked into the mixing barrel, without the need to set up an additional pump body, thereby saving energy.

[0027] 2. A processing device and process for a HDPE double-wall corrugated pipe. Through the cooperation among a disc, an upper protrusion, a U-section inner tube, a limiting rod and a second spring, as the shaft rotates, the upper protrusion rotates accordingly. During the rotation of the upper protrusion, the top block and the limiting rod can be pushed upward, and the connecting frame and the U-section inner tube move upward accordingly. In cooperation with the second spring, the U-section inner tube can quickly achieve up and down reciprocating motion, that is, vibration, and quickly screen the raw materials in the U-section inner tube to improve the processing efficiency.

[0028] 3. A processing device and process for a HDPE double-wall corrugated pipe. Through the mutual cooperation among a long rod, a premixing rod assembly, a through cavity, a lower protrusion, a cylinder, a piston rod and a third spring, as the long rod and the second small gear rotate, the first large gear, the first small gear and the second large gear are driven to rotate, and the lower protrusion rotates accordingly. During the rotation of the lower protrusion, the semicircular block and the piston rod are pushed downward, and cooperate with the third spring to make the piston rod move up and down reciprocatingly, and perform a pumping operation, so that the liquid raw material contained outside can be first sucked into the cylinder, and then discharged through the hollow block, the drain pipe and the through cavity, and finally discharged through the various through holes, so that the liquid raw material can be intermittently injected into the mixing chamber and premixed with the powdered raw material. The synergistic effect of various components makes the entire mixing process more efficient and stable, ensuring product quality.

[0029] 4. A processing device and process for a HDPE double-wall corrugated pipe. Through the cooperation between a block, a through hole, a first spring and a premixing rod, as the amount of liquid raw material in the premixing rod increases, the hydraulic pressure increases, pushing the block to move to the side away from the long rod, exposing the through hole and allowing the liquid raw material in the hollow cavity to spray out. As the hydraulic pressure in the premixing rod decreases, the block slides back into the premixing rod to seal the through hole, which can effectively prevent the external powdered raw material from blocking the through hole and ensure the normal spraying of the liquid raw material afterwards.

[0057] Step 2: During the rotation of the upper mixing rod mechanism 2, the screening mechanism 5 is driven to vibrate. The vibrating screening mechanism 5 quickly screens the powdered raw materials inside. The powdered raw materials that fall after screening sequentially enter the guide bucket 11, the first mixing tube 12, the mixing chamber 13 and the second mixing tube 14. During the process of the powdered raw materials passing through the first mixing tube 12, the mixing chamber 13 and the second mixing tube 14, the upper mixing rod mechanism 2 and the lower mixing rod mechanism 3 stir and complete preliminary mixing.

[0058] Step three, during the rotation of the lower mixing rod mechanism 3, the first large gear 9 and the first small gear 10 are driven, and then the liquid pumping mechanism 6 is driven to repeatedly pump out the liquid HDPE double-wall corrugated pipe raw material. The liquid raw material is sprayed out from the mixing chamber 13 and preliminarily mixed with the powdered raw material. Finally, the preliminarily mixed raw material falls into the bottom of the inner cavity of the mixing barrel 1. Under the action of the lower mixing rod mechanism 3, the raw materials are thoroughly mixed, and then the sealing door is opened to take out the mixed raw materials for the next processing operation.
