[0002] A coal lock is a pressure vessel used in the chemical industry for intermittently adding coal to a gasifier. It typically has an upper valve at the top and a lower valve at the bottom, forming a double-sealing system to ensure media isolation during the coal feeding process. Currently, to protect the upper valve of the coal lock from impacts by coal dust or particles, and to prevent wear, ash accumulation, or high-temperature damage, a coal baffle is usually installed. However, existing coal baffles are mostly one-piece structures, which cannot be quickly installed during use, nor can they be easily disassembled for maintenance of the upper valve. Their use is not flexible and convenient enough and needs improvement. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a coal lock valve cover that is easy to connect and install, so as to solve the above problems.

The bottoms of both the left and right cover bodies are open, and a slider is fixedly connected to the outer side of the bottom of both. A T-shaped groove is opened at the bottom of the slider. T-shaped guides are fixed on the top of the coal lock container on both sides of the feed pipe. The slider is slidably mounted on the guide rail on the same side via a slide groove. Left fixing plates are fixed at both the front and rear ends of the outer side of the left cover. A rotating shaft is rotatably mounted on the right side of the left fixing plate. A limit block is fixedly connected to the right end of the rotating shaft. Right fixing plates are fixed at both the front and rear ends of the outer side of the right cover. A rectangular through groove is opened on the right fixing plate. The left and right covers abut against each other, and their tops are fitted onto the outside of the feed pipe through corresponding slots. The limit block corresponds to the through groove on the same side and passes through the corresponding through groove. After the limit block passes through the corresponding through groove, its left side is flush with the right side of the right fixing plate and abuts against the right side of the right fixing plate after rotating 90 degrees.
[0005] Preferably, the groove is adapted to the corresponding guide rail.
[0006] Preferably, the diameter of the rotating shaft is smaller than the width of the corresponding through groove.
[0007] Preferably, the limiting block is adapted to the corresponding through slot.
[0008] Preferably, both the left and right covers are made of aluminum foam.
[0009] Preferably, the valve stem of the upper valve faces the right cover and a wire hole is provided on the corresponding side of the right cover.
[0010] The beneficial effects of this utility model are as follows: When installing the coal retaining cover, simply align the slider on the right cover with the corresponding guide rail and slide the right cover to the left until the top of the right cover abuts against the feed pipe. Then, align the slider on the left cover with the corresponding guide rail and slide the left cover to the right while simultaneously pressing down on the right cover until the top of the left cover also abuts against the feed pipe. At this point, the left and right covers abut against each other, and the limiting block passes through the corresponding through slot to the right side of the right fixing plate. Next, rotate the limiting block 90 degrees using the pivot to make it perpendicular to the corresponding through slot, so that the limiting block presses against the right fixing plate, fixing the left and right covers together, thus completing the installation of the entire coal retaining cover. When it is necessary to disassemble the coal retaining cover, simply rotate the limiting block 90 degrees to align it with the corresponding through slot, release the lock between the left and right covers, then move the two covers away from each other, and slide the left and right covers off the corresponding guide rails. Therefore, the coal retaining cover is designed as a split structure, which allows for flexible and convenient disassembly and assembly, making it easy to operate, time-saving, labor-saving, and more practical.

Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 10 As shown, a coal lock valve and coal-blocking cover that is easy to connect and install includes an upper valve 3 on the feed pipe 2 at the top of the coal lock container 1 and a coal-blocking cover outside the upper valve 3. The coal-blocking cover includes a left cover body 4 and a right cover body 5. Both the left cover body 4 and the right cover body 5 are semi-cylindrical structures. The tops of the left cover body 4 and the right cover body 5 are closed, and a semi-circular groove 6 is opened at the center of the opposite end of the top of the two. The bottoms of the left cover body 4 and the right cover body 5 are open, and a slider 7 is fixedly connected to the outer side of the bottom of the two. A T-shaped groove 8 is opened at the bottom of the slider 7. T-shaped guide rails 9 are fixed on the top of the coal lock container 1 on both sides of the feed pipe 2. The slider 7 slides on the guide rail 9 on the same side through the groove 8. Left fixing plates 10 are fixed at both the front and rear ends of the outer side of the left cover 4. A rotating shaft 11 is rotatably provided on the right side of the left fixing plate 10. A limiting block 12 is fixedly connected to the right end of the rotating shaft 11. Right fixing plates 13 are fixed at both the front and rear ends of the outer side of the right cover 5. A rectangular through groove 14 is provided on the right fixing plate 13. The left cover 4 and the right cover 5 abut against each other and their tops are fitted onto the outer side of the feed pipe 2 through the corresponding slots 6. The limiting block 12 corresponds to the through groove 14 on the same side and passes through the corresponding through groove 14. After the limiting block 12 passes through the corresponding through groove 14, its left side is flush with the right side of the right fixing plate 13 and abuts against the right side of the right fixing plate 13 after rotating 90 degrees. When installing the coal retaining cover, first align the slider 7 on the right cover 5 with the corresponding guide rail 9 and slide the right cover 5 to the left until the top of the right cover 5 abuts against the feed pipe 2. Then, align the slider 7 on the left cover 4 with the corresponding guide rail 9 and slide the left cover 4 to the right while pressing down on the right cover 5 until the top of the left cover 4 also abuts against the feed pipe 2. At this point, the left cover 4 and the right cover 5 are in contact, and the limiting block 12 passes through the corresponding through slot 14 to the right side of the right fixing plate 13. Next, rotate the limiting block 12 90 degrees through the rotating shaft 11 so that it is perpendicular to the corresponding through slot 14, so that the limiting block 12 presses against the right fixing plate 13, fixing the left cover 4 and the right cover 5 together, thus completing the installation of the entire coal retaining cover. When the coal retaining cover needs to be disassembled, simply rotate the limiting block 12 90 degrees to align it with the corresponding through slot 14, release the lock between the left cover 4 and the right cover 5, then move the two covers away from each other and slide the left cover 4 and the right cover 5 off the corresponding guide rail 9. This design of the coal retaining cover as a split structure allows for flexible and convenient disassembly and assembly, making it simple, time-saving, and labor-saving, and more practical.
[0014] In this embodiment, the slide groove 8 is adapted to the corresponding guide rail 9 to ensure the smooth sliding connection and installation of the left cover and the right cover.
[0015] In this embodiment, the diameter of the rotating shaft 11 is smaller than the width of the corresponding through groove 14, so as to ensure that the limiting block 12 can smoothly pass through the corresponding through groove 14 to the right side of the right fixing plate 13.
[0016] In this embodiment, the limiting block 12 is adapted to the corresponding through slot 14 to ensure that the limiting block 12 can smoothly pass through the corresponding through slot 14 to the right side of the right fixing plate 13.
