[0004] When the existing feeding structure for concrete waterproofing agent processing and production is in use, the powder material is affected by the environment and may become damp and cause agglomeration. After entering the feeding barrel, the probability of the feeding barrel being blocked will increase, and the large particle agglomerates may be unevenly dispersed during the subsequent stirring reaction process, thereby affecting the product quality. At the same time, it is difficult for the staff to accurately control the amount of material added after working for a long time, resulting in slightly more or less material being added, which has a certain impact on the quality of the concrete waterproofing agent product.

[0026] A feeding structure for processing and producing a concrete waterproofing agent comprises a feeding pipe 1.

[0027] In this embodiment: CN217731672U discloses a feeding structure for processing and producing concrete waterproofing agents. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "the existing feeding structure for processing and producing concrete waterproofing agents is affected by the environment during use. The powder material may be affected by moisture and cause agglomeration. After entering the feeding barrel, the probability of clogging of the feeding barrel increases, and large particle agglomerates may be unevenly dispersed during the subsequent stirring reaction process, thereby affecting the product quality.

Therefore, in order to solve this technical problem, a screen and a flow sensor are added to this application document;

[0028] More specifically:

[0030] In combination with the above content: A feeding structure for the processing and production of concrete waterproofing agent, including a feeding pipe 1, the feeding pipe 1 is fixed to the first motor 4 by bolts, the output end of the first motor 4 is fixed to the first rotating shaft 2 by bolts, the outer side of the first rotating shaft 2 is welded and fixed with a screw blade 3, the left bottom end of the feeding pipe 1 is welded and fixed with a discharge pipe 14, the right top end of the feeding pipe 1 is welded and fixed with a feed pipe 5, the top of the feed pipe 5 is fixed with a gate valve 6 by bolts, the left end of the outer side of the feed pipe 5 is fixed with a flow sensor 8 by bolts, the top of the gate valve 6 is fixed with a hopper 7 by bolts, the left end of the outer side of the hopper 7 is fixed with a controller 9 by bolts, the left end of the hopper 7 is fixed with a second motor 10 by bolts, the output end of the second motor 10 is fixed with a second rotating shaft 11 by bolts, the outer side of the second rotating shaft 11 is welded and fixed with a cam 12, the inner side of the hopper 7 is slidably connected with a screen 13, the first rotating shaft 2 is rotatably connected to the left and right ends of the feeding pipe 1 by bearings, the outer contour of the screw blade 3 is in contact with the inner side of the feeding pipe 1, and the second rotating shaft 11 is rotatably connected to the left and right ends of the feeding hopper 7 by bearings.

[0031] In this embodiment: through design coordination, the screen 13 is used to filter the material to screen out larger particles, reduce the possibility of material clogging the pipeline and uneven material mixing, and the flow meter is used to accurately control the delivery of the material to avoid deviations in material delivery caused by staff operating errors, thereby avoiding the quality of the waterproofing agent.

[0032] In an optional embodiment, the controller 9 is electrically connected to the flow sensor 8 , the gate valve 6 and the second motor 10 . After the flow sensor 8 detects a prescribed flow rate, the controller 9 controls the gate valve 6 and the second motor 10 to close.

[0033] In this embodiment, during the feeding process, the flow sensor 8 and the controller 9 can cooperate to make the amount of material fed into the feeding pipe 1 more accurate.

[0034] In an optional embodiment, the cam 12 is elliptical, and the top end of the cam 12 is always in contact with the bottom end of the screen 13 during the rotation of the cam 12 .

[0035] In this embodiment, when the cam 12 rotates along with the second rotating shaft 11, the screen 13 slides up and down along with the height change of the top end of the cam 12, thereby achieving the purpose of filtering the material.

[0036] In an optional embodiment, an annular chute is provided on the inner side of the feeding hopper 7 , and the inner wall of the annular chute is in contact with the outer side of the screen 13 .

[0037] In this embodiment, the screen 13 can slide along the annular chute, making the sliding process more stable.

[0038] In an optional embodiment, the outer diameter of the screw blade 3 is consistent with the inner diameter of the feed tube 1 , and the length of the screw blade 3 is consistent with the length of the feed tube 1 .

[0039] In this embodiment, after the material enters the feeding pipe 1 , it can move to the left under the push of the screw blade 3 , and less material remains in the feeding pipe 1 .

[0040] In an optional embodiment, the bottom end of the feeding hopper 7 is an inclined surface, and the feeding hopper 7 is inclined downward from the outside to the inside.

[0041] In this embodiment, the material can slowly slide down along the inclined surface under the action of gravity, so as to avoid the material falling too quickly and causing the feed pipe 5 to be blocked.

When the material passes through the screen 13, the second motor 10 drives the second rotating shaft 11 and the cam 12 to rotate. Since the top height of the cam 12 changes continuously during the rotation process, the screen 13 slides up and down with the change of the top height of the cam 12 under the action of the cam 12 and gravity, filtering the passing material. When the flow sensor 8 detects that the filtered material passing through the feed pipe 5 reaches the specified amount, the controller 9 controls the gate valve 6 and the second motor 10 to be closed, so that the amount of material entering the feed pipe 1 is a more accurate value. At the same time, the staff can understand the situation of the material entering the feed pipe 5 by observing the changes in the second motor 10. After the material enters the feed pipe 1, the first rotating shaft 2 and the screw blade 3 are driven by the first motor 4 to rotate. When the screw blade 3 rotates, it pushes the material to the left, so that the material is discharged from the discharge pipe 14.
