DETAILED DESCRIPTION

[0034] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0035] Example 1: Please refer to Figure 1-Figure 4 and Figure 7-Figure 8 As shown, the existing pipe blockage cleaning device is not convenient to reduce the blockage probability during the transportation process. In order to solve this technical problem, this embodiment discloses the following technical content;

[0036] A pipe blockage cleaning device suitable for the supply process of cementitious materials, comprising a material conveying pipe 1 connected to the output end of a down-drawn silo pump, and a conveying valve 2 is installed on the material conveying pipe 1, a connecting pipe 3 is installed on the material conveying pipe 1, and a drain valve 4 is connected to the upper end of the connecting pipe 3, and a circulating drain pipe 5 is connected between the drain valve 4 and the upper end of the silo;

[0037] The side wall of the connecting pipe 3 is fixedly connected and installed with a pressure regulating pipe 6, and a pressure regulating component is arranged inside the pressure regulating pipe 6 to adjust the internal pressure of the pressure regulating pipe 6;

[0038] An outer tube fixing frame 17 is fixedly installed on the outer side of the material conveying pipe 1 , and a shock component is arranged on the outer tube fixing frame 17 to realize vibration and clearing of the material conveying pipe 1 .

[0039] The upper end of the circulating and draining pipe 5 passes through the upper end of the silo, and the upper end of the circulating and draining pipe 5 is curved, and the bending angle of the upper end of the circulating and draining pipe 5 is greater than 90°, and the upper end of the circulating and draining pipe 5 faces downward.

[0040] The pressure regulating assembly includes a sealing piston rubber 7 which is interference-slidably installed on the inner side of the pressure regulating tube 6, and a first spring 9 is fixedly connected between the sealing piston rubber 7 and the inner wall of the right end of the pressure regulating tube 6, and a movable guide column 8 is fixedly connected to the right side of the sealing piston rubber 7, and the movable guide column 8 passes through the right end of the pressure regulating tube 6.

[0041] The shock assembly includes a lifting movable frame 18 that is telescopically installed on the external fixed frame 17 of the tube, and the lifting movable frame 18 is arranged in a U-shaped structure, and a first magnetic block 19 is evenly fixedly installed on the upper end of the lifting movable frame 18, and a second magnetic block 20 is fixedly installed below the right end of the movable guide column 8. The magnetic poles of the opposite surfaces of the first magnetic block 19 and the second magnetic block 20 are the same, and when the first magnetic block 19 passes over the second magnetic block 20, the lifting movable frame 18 is pulled upward by the magnetic force.

[0042] A second spring 21 is evenly and fixedly connected between the external fixing frame 17 and the lifting movable frame 18, and a vibrating striking piece 22 is evenly and fixedly installed on the lower surface of the lifting movable frame 18, and the vibrating striking piece 22 is arranged in an arc-shaped structure. At the same time, the vibrating striking piece 22 initially fits against the outer wall of the material conveying pipe 1.

[0043] Through the above technical solution, when material is conveyed inside the material conveying pipe 1 and partial blockage occurs, the air pressure inside the material conveying pipe 1 will gradually increase. At this time, the sealing piston rubber 7 will slide on the inner side of the sealing piston rubber 7, so that the movable guide column 8 extends and moves toward the right end of the pressure regulating tube 6. At this time, the first magnetic block 19 set at the right end of the movable guide column 8 will intermittently pass over the first magnetic block 19 at different positions on the lifting movable frame 18, so that the lifting movable frame 18 and the external fixed frame 17 are elastically lifted and lowered under the action of magnetic force, thereby driving the vibration knocking member 22 set on the lower surface of the lifting movable frame 18 to automatically knock on the surface of the material conveying pipe 1, thereby causing the material conveying pipe 1 to vibrate, thereby promoting the loosening of the material in the blocked part, avoiding further blockage, and thereby reducing the probability of blockage during transportation.

[0044] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. The existing pipe blockage cleaning device only relies on negative pressure to achieve blockage removal, so that the blockage material cannot be completely discharged. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 2-Figure 8 As shown;

[0045] A clearing rotating rod 10 is rotatably mounted on the inner side of the material conveying pipe 1, and a storage groove 12 is evenly provided on the clearing rotating rod 10, and a cleaning assembly is rotatably mounted on the inner side of the storage groove 12; the clearing rotating rod 10 and the material conveying pipe 1 are coaxially arranged, and the clearing rotating rod 10 is elastically rotatably mounted on the inner side of the material conveying pipe 1, and a winding wheel is fixedly mounted on the outer side of the left end of the clearing rotating rod 10, and a linkage pull rope 11 is wound around the outer side of the winding wheel, and the upper end of the linkage pull rope 11 is fixedly connected to the outer side of the sealing piston film 7, and the clearing rotating rod 10 is pulled by the linkage pull rope 11 to perform synchronous elastic rotation during the movement of the sealing piston film 7. The cleaning assembly includes a rotating seat 13 that is evenly elastically rotatably mounted on the inner side of the storage groove 12, and the rotating seat 13 is elastically rotated under the action of centrifugal force during the rotation of the clearing rotating rod 10. The cleaning assembly also includes a cleaning bristle 14 evenly fixedly mounted on the right end of the rotating seat 13, and after the rotating seat 13 is elastically rotated and erected, the cleaning bristles 14 at the end thereof are attached to the inner wall of the material conveying pipe 1, and the inner wall of the material conveying pipe 1 is cleaned by rotating along with the unblocking rotating rod 10. An elastic capsule 15 is fixedly connected between the rotating seat 13 and the inner wall of the storage tank 12, and an air pipe 16 is connected to the outside of the elastic capsule 15, and a filter structure is provided at the port of the air pipe 16, and the port of the air pipe 16 faces the cleaning bristle 14.

[0046] By means of the above technical scheme, when the material conveying pipe 1 is blocked during the conveying process, the air pressure inside the material conveying pipe 1 will gradually increase, so that the air pressure inside the pressure regulating pipe 6 will increase synchronously. At this time, the sealing piston rubber 7 will slide along the inner wall of the pressure regulating pipe 6 under the action of the air pressure. At this time, the pressure regulating pipe 6 will pull the unblocking rotating rod 10 through the linkage pull rope 11 to elastically rotate, and the movable guide column 8 will slide and adjust. When the air pressure inside the material conveying pipe 1 is too high, the unblocking valve 4 is opened, so that the circulating unblocking pipe 5 can reverse the blocked material inside the material conveying pipe 1 through the negative pressure. At the same time, the air pressure inside the pressure regulating pipe 6 will gradually decrease. At this time, the sealing piston rubber 7 will be reset under the elastic force of the first spring 9, and the movable guide column 8 will synchronously move to the left and reset, so that the first magnetic block 19 at the right end of the movable guide column 8 will gradually pass through the second magnetic block 20 at a different position again, so that the lifting movable frame 18 will reciprocate elastically lift and lower under the action of the magnetic force, and the vibrating knocking piece 22 on the lower surface of the lifting movable frame 18 will move the material conveying pipe 1 back and forth. The repeated knocking makes the material conveying pipe 1 vibrate to loosen the blocked material inside the material conveying pipe 1, so as to facilitate the extraction of the blocked material. As the material is extracted, the clearing rotating rod 10 rotates and resets under the elastic force of the torsion spring, so that the rotating seat 13 rotates and stands up due to the centrifugal force during the rotation process, and then pops out of the storage accommodating groove 12, so that the cleaning bristles 14 at the end of the rotating seat 13 fit the inner wall of the material conveying pipe 1, so that when the clearing rotating rod 10 drives the rotating seat 13 to rotate, the cleaning bristles 14 at the end of the rotating seat 13 can be cleaned. Part of the material remaining on the inner wall of the material conveying pipe 1 is cleaned to further improve the clearing effect. When the rotating seat 13 rotates upright, it will cooperate with the inner wall of the storage groove 12 to stretch the elastic capsule 15, so that the elastic capsule 15 can inhale air through the air pipe 16. When the clearing is completed, the rotating seat 13 elastically rotates and resets, which will squeeze the elastic capsule 15, so that the elastic capsule 15 can blow out the inhaled air again through the air pipe 16, thereby realizing automatic cleaning of the residual material on the outside of the cleaning bristles 14 and avoiding the occurrence of material residue.

[0047] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
