Description

Technical Field

[0001] This utility model belongs to the technical field of material transportation equipment, specifically relating to a maintenance structure for a PTA silo rotary valve. Background Technology

[0002] The function of scrapers in tubular chain conveyors: Scrapers are components mounted on the chain, and their main function is to propel materials along a specified direction within a closed pipe. Since tubular chain conveyors are often used in complex lines with combinations of horizontal, inclined, or vertical configurations, scrapers need to adapt to conveying requirements at different angles.

[0003] When using a tubular chain conveyor, the scrapers need to be inspected and replaced after a long period of use to avoid damage to the scrapers and poor material conveying efficiency. Therefore, a maintenance location is needed to facilitate the repair and replacement of the scrapers. Utility Model Content

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a maintenance structure for a PTA silo rotary valve, including a maintenance box, with connection ports on both the left and right sides of the maintenance box, and a discharge connection pipe and a feed connection pipe integrally provided with the connection ports on both sides of the maintenance box, characterized in that: a scraper for transporting materials is provided between the feed connection pipe and the discharge connection pipe, and adjacent scrapers are connected by a chain, and a lifting base is slidably inserted into the bottom of the maintenance box, and an auxiliary discharge port corresponding to the outside of the connection port is provided on the top of the lifting base.

[0006] Preferably, a cover plate is inserted into the top of the maintenance box, a first handle is provided on the top of the cover plate, pressure blocks are provided on both the left and right sides of the cover plate, and pressure seats are provided on the left and right sides of the maintenance box below the pressure blocks. A locking buckle is rotatably provided on one side of the pressure seat, and a locking bolt is provided on the top of the locking buckle.

[0007] Preferably, slide rails are installed on the lower left and right sides of the inspection box, and sliders are slidably mounted on the slide rails. Connecting rods extending downward are inserted into the sliders, and plug blocks are inserted into the bottom ends of the connecting rods. One end of the plug blocks is fixedly connected to the lifting base.

[0008] Preferably, a side frame is connected between the two sliders on the same side, a positioning block is inserted into the middle of the side frame, a pressing block is provided on the outside of the positioning block, and positioning seats for easy insertion of the positioning block are provided on the left and right sides of the maintenance box.

[0009] The beneficial effects of this utility model are as follows: By setting up a maintenance box between the pipes, which is equipped with inlet and outlet connecting pipes on both sides to transport materials, the maintenance box allows for the replacement and maintenance of scrapers that need to be replaced during machine stop. At the same time, a lifting base is slidably inserted into the bottom of the maintenance box. The lifting base is equipped with an auxiliary discharge port on the top, which is located at the bottom of the connecting ports on both sides. When the scraper is being transported, it can prevent material from accumulating inside the maintenance box. During maintenance, the lifting base slides down, and with the help of the side connecting rod and slide rail, it has a limiting effect to prevent it from falling off. This allows the scraper and material to fall into the space reserved by the lifting base, so that the scraper that needs to be replaced can be replaced. Attached Figure Description

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: A maintenance structure for a PTA silo rotary valve, such as... Figures 1-3 As shown, the system includes a maintenance box 1. Both the left and right sides of the maintenance box 1 have connection ports 11. The connection ports 11 on both sides are integrally provided with a discharge connection pipe 12 and a feed connection pipe 13. A scraper 51 for transporting materials is provided between the feed connection pipe 13 and the discharge connection pipe 12. Adjacent scrapers 51 are connected by a chain 52. A lifting base 41 is slidably inserted into the bottom of the maintenance box 1. The top outer ring of the lifting base 41 and the bottom inner ring of the maintenance box 1 are provided with bending parts to prevent the lifting base 41 from sliding out and to provide a limiting effect. The top of the lifting base 41 has an auxiliary discharge port 410 corresponding to the outside of the connection port 11.

[0016] The top of the maintenance box 1 is connected to a cover plate 2, and the top of the cover plate 2 is provided with a first handle 21. The left and right sides of the cover plate 2 are provided with pressure blocks 22. The left and right sides of the maintenance box 1 are provided with pressure seats 23 below the pressure blocks 22. One side of the pressure seat 23 is provided with a locking buckle 24, and the top of the locking buckle 24 is provided with a locking bolt 25.

[0017] Slide rails 42 are installed on the lower left and right sides of the maintenance box 1. Slider blocks 43 are slidably mounted on the slide rails 42. When the sliders 43 are at their highest point, the auxiliary discharge port 410 on the top of the lifting base 41 is aligned with the bottom of the connecting ports 11 on both sides. A downwardly extending connecting rod 44 is inserted into the slider 43. A plug block 45 is inserted into the bottom end of the connecting rod 44. One end of the plug block 45 is fixedly connected to the lifting base 41. A side frame 46 is connected between the two sliders 43 on the same side. A positioning block 47 is inserted into the middle of the side frame 46. A pressing block 48 is provided on the outside of the positioning block 47. Positioning seats 49 are provided on the left and right sides of the maintenance box 1 to facilitate the insertion of the positioning blocks 47.

[0018] The principle of this utility model is as follows: When the internal scraper 51 needs to be inspected, the body of the inspection box 1 is made of transparent material, which makes it easy to observe the internal scraper 51. When it needs to be replaced or repaired, when the scraper 51 to be inspected is moved into the inspection box 1, the pressing blocks 48 on both sides are pulled out so that the positioning block 47 and the positioning seat 49 are separated. At this time, the bottom lifting base 41 interacts downward with the connecting rod 44 and the slider 43 is limited on the slide rail 42. After the lifting base 41 falls to the maximum distance between the slide rail 42 and the slider 43, the inside of the inspection box 1 will have a larger space reserved due to the fall of the lifting base 41, so that the material between the scrapers 51 falls. Then the top cover 2 is opened, and the scraper 51 can be replaced.

[0019] After the replacement is completed, push the bottom lifting base 41 upward, and then, after the positioning block 47 is inserted into the corresponding positioning seat 49, close the top cover 2 to complete the replacement.

[0020] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
