[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , 2 , 3, and 4, the utility model provides a technical solution: an alkali washing device for removing paint and slag from scrap iron barrel fragments, comprising: a No. 1 conveying pipe 3, the No. 1 conveying pipe 3 is fixedly installed on the top of the bottom plate 1, a No. 1 spiral conveying rod 4 is rotatably installed in the middle of the No. 1 conveying pipe 3, a plurality of knocking hammers 6 are equidistantly installed on the outer side of the No. 1 spiral conveying rod 4, and a plurality of chip removal holes 15 are equidistantly opened at the bottom of the No. 1 conveying pipe 3; an alkali washing tank 14 is placed below the end of the No. 1 conveying pipe 3, and the alkali washing tank 14 The alkali washing tank 14 is fixedly connected to the bottom plate 1 and is a rectangular cleaning tank, the interior of which is filled with alkaline solution, such as sodium hydroxide (NaOH), potassium hydroxide (KOH), calcium hydroxide (Ca(OH)2) and other alkaline compounds. A No. 2 feed pipe 9 is fixedly connected to the interior of the alkali washing tank 14, and a No. 2 spiral conveying rod 10 is rotatably connected to the interior of the No. 2 feed pipe 9. A water-permeable hole 17 is provided on the outer side of the No. 2 feed pipe 9 and in a section located inside the alkali washing tank 14, so that the alkali washing liquid can enter the No. 2 feed pipe 9.

[0022] It should be noted that, in the utility model, the fragments generated when the iron barrel is recycled are put into the feeding port at the top of the No. 1 conveying pipe 3, and the No. 1 spiral conveying rod 4 cooperates with the No. 1 conveying pipe 3 to form a spiral conveyor, and the fragments are conveyed obliquely upward along the No. 1 conveying pipe 3 through the No. 1 spiral conveying rod 4. During the conveying process, the hammer 6 contacts the fragments and strikes the fragments, so that the surface debris and the paint are knocked away, and then enter the dust collecting box 2 through the chip removal hole 15 at the bottom of the No. 1 conveying pipe 3. The broken iron pieces after the impact and cleaning fall into the discharge pipe 7, and the alkali solution enters the discharge pipe 7 and the No. 2 conveying pipe 9 respectively through the soaking hole 8 and the water permeable hole 17. The fragments are soaked and cleaned after entering the discharge pipe 7, and then fall into the No. 2 conveying pipe 9. The No. 2 spiral conveying rod 10 conveys the fragments upward along the No. 2 conveying pipe 9. During the conveying process, the fragments collide with each other, thereby realizing the flipping of the fragments themselves, thereby realizing the stirring of the fragments, which can be fully mixed with the alkali solution, and then The fragments are then conveyed upward by the No. 2 spiral conveying rod 10. When the fragments are conveyed to a height higher than the alkali washing tank 14, the excess alkali solution on the outside thereof falls through the water filtering hole 11 and is thus recovered into the alkali washing tank 14. Then, the separated iron pieces are discharged into the alkali washing tank 14 through the discharge pipe 13. Through the spiral conveying mechanism of the No. 1 conveying pipe 3 and the action of the striking hammer 6, the debris and paint on the surface of the scrap iron barrel fragments can be efficiently removed to ensure that the fragments are cleaned before alkali washing. The equipment can not only clean the scrap iron barrel fragments, but also convey the cleaned fragments to the alkali washing tank 14 for further treatment to ensure that the fragments are thoroughly cleaned. Alkaline solution is injected into the alkali washing tank 14, and through the conveying and stirring of the No. 2 conveying pipe 9 and the No. 2 spiral conveying rod 10, the alkali solution can be fully mixed with the fragments to ensure that the surface and the inside of the fragments are fully cleaned. The water filtering hole 11 recovers the excess alkali solution into the alkali washing tank 14, realizing the recycling of the alkali solution and saving resource costs.

The chip removal hole 15 is located at the position where the No. 1 conveying pipe 3 is located inside the dust box 2. The dust box 2 can effectively collect dust and debris generated during the processing process to keep the surrounding environment clean and safe. The No. 1 motor 16 drives the No. 1 spiral conveying rod 4 to rotate, so that the debris is conveyed through the No. 1 spiral conveying rod 4. The reset spring 5 is fixedly connected to the knocking hammer 6. During the conveying process, the reset spring 5 is deformed by resistance. When it is offset from the resistance, under the elastic action of the reset spring 5, the surrounding iron sheets are knocked and impacted, ensuring that the knocking hammer can return to the starting position in time after the cleaning action, thereby ensuring the normal operation of the equipment and continuous cleaning operations.

[0025] See also Figure 2 As shown, a discharge pipe 7 is fixedly connected to one side of the No. 2 feed pipe 9, and the discharge pipe 7 is located below the discharge port of the No. 1 feed pipe 3.

Under the action of gravity, the iron sheet enters the No. 2 feed pipe 9 and is transported upward by the No. 2 spiral conveying rod 10. During this process, the iron sheet keeps rolling and can enter the No. 2 feed pipe 9 through the water permeable hole 17 to fully contact the alkali solution inside. When transported to the high alkali solution level, the alkali solution falls back into the alkali washing tank 14 through the water filter hole 11.
