[0024] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a buffer tank plug with a protective structure, including a plug body 1, a spherical boss 2 is fixedly installed on the inner wall of the plug body 1, and the coal chemical black water can be guided to the guide slope 3 by setting the spherical boss 2, and the inner wall of the plug body 1 is fixedly installed with the guide slope 3, and the coal chemical black water can be guided to the periphery of the plug body 1 by utilizing the guide slope 3, and a movable groove 4 is opened on the spherical boss 2, and a protective mechanism 5 for improving the service life of the plug body 1 is arranged on the plug body 1, and the protective mechanism 5 can be arranged to prevent the coal chemical black water from directly impacting the plug body 1, thereby improving the service life of the plug body 1.

[0025] The above-mentioned protection mechanism 5 includes a sliding rectangular block 51, a protection plate 52, a spring spring 53, a limit plate 54, a rotating shaft 55, a rotating rectangular block 56, and a rectangular groove 57; the sliding rectangular block 51 is slidably connected to the inner wall of the movable groove 4, and the outer wall of the sliding rectangular block 51 is fixedly installed with the limit plate 54, the inner wall of the sliding rectangular block 51 is rotatably connected with the rotating shaft 55, and the top of the rotating shaft 55 is fixedly installed with a rotating rectangular block 56, and the rotating rectangular block 56 has the same length as the four sides of the sliding rectangular block 51. Rotating the rotating rectangular block 56 and the rotating rectangular block 56 will drive the rotating shaft 55 to rotate synchronously, and compress the spring spring 53, and keep the rotating rectangular block 56 and the sliding rectangular block 51 in an overlapping state. At this time, the protective plate 52 can be directly removed from the sliding rectangular block 51 for replacement. A rectangular groove 57 is provided on the protective plate 52, and the protective plate 52 is made of iron plate as a whole, which has lower cost and greatly reduces the blocking plate body 1 The cost of use is that the inner wall of the rectangular groove 57 is fitted on the outer wall of the sliding rectangular block 51, and the setting of the protective plate 52 can block the rushing coal chemical black water. The protective plate 52 is used to resist the impact of the coal chemical black water to prevent the coal chemical black water from directly impacting the plugging plate body 1, causing the surface of the plugging plate body 1 to be corroded. The upper surface of the protective plate 52 is fitted with the bottom of the rotating rectangular block 56, and the protective plate 52 is sleeved on the outer wall of the sliding rectangular block 51 through the rectangular groove 57. One side of the clockwork spring 53 is fixedly mounted on the outer wall of the rotating shaft 55, and the other side of the clockwork spring 53 is fixedly mounted on the inner wall of the sliding rectangular block 51. The elasticity of the clockwork spring 53 can drive the rotating shaft 55 to rotate and reset, and then can drive the rotating rectangular block 56 to rotate and reset, so that the rotating rectangular block 56 and the sliding rectangular block 51 are staggered. The staggered rotating rectangular block 56 can be used to limit the top of the protective plate 52.

[0026] The above-mentioned sliding rectangular block 51 is provided with a buffer mechanism 6 for protecting the buffer tank. By providing the buffer mechanism 6, the impact force caused by the coal chemical black water to the plugging plate body 1 can be reduced. The buffer mechanism 6 includes an energy absorbing spring 61, a push rod 62, a limit block 63, and a reset spring 64; one end of the energy absorbing spring 61 is fixedly installed at the bottom of the sliding rectangular block 51, and the other end of the energy absorbing spring 61 is fixedly installed on the inner wall of the movable groove 4. When the impact force of the coal chemical black water is too large, causing the protective plate 52 to impact the sliding rectangular block 51, the sliding rectangular block 51 will collapse into the inside of the movable groove 4 and compress the energy absorbing spring 61. The energy absorbing spring 61 can be used to absorb the impact force of the sliding rectangular block 51, and the impact force of the sliding rectangular block 51 is converted into the elastic potential energy of the energy absorbing spring 61, thereby further reducing the impact force caused by the coal chemical black water to the plugging plate body 1. 4 is slidably connected with a push rod 62, and the push rod 62 passes through the limit plate 54, the top of the push rod 62 is attached to the lower surface of the protective plate 52, and the bottom of the push rod 62 is fixedly installed with a limit block 63. When the coal chemical black water impacts the protective plate 52, the protective plate 52 will collapse toward the inside of the plugging plate body 1. At the same time, the protective plate 52 will squeeze the push rod 62, so that the push rod 62 drives the limit block 63 to move to one end away from the protective plate 52 and stretch the reset spring 64. The outer wall of the push rod 62 is sleeved with a reset spring 64, one end of the reset spring 64 is fixedly installed on the upper surface of the limit block 63, and the other end of the reset spring 64 is fixedly installed on the lower surface of the limit plate 54. The reset spring 64 can convert the impact force of the coal chemical black water on the protective plate 52 into the elastic potential energy of the reset spring 64, thereby reducing the impact force of the coal chemical black water on the plugging plate body 1.

[0027] Working principle: During the use of the plugging plate body 1, the setting of the protective plate 52 can block the rushing coal chemical black water, and the protective plate 52 is used to resist the impact of the coal chemical black water, so as to prevent the coal chemical black water from directly impacting the plugging plate body 1, causing the surface of the plugging plate body 1 to be corroded, thereby increasing the service life of the plugging plate body 1. When the protective plate 52 is severely corroded and needs to be replaced, the rotating rectangular block 56 is rotated. At the same time, the rotating rectangular block 56 will drive the rotating shaft 55 to rotate synchronously, compress the spring spring 53, and keep the rotating rectangular block 56 and the sliding rectangular block 51 in an overlapping state. At this time, the protective plate 52 can be directly removed from the sliding rectangular block 51, and the rectangular groove 57 on the replaced protective plate 52 is aligned with the rotating rectangular block 56, and pressed downward to make the new protective plate 52 sleeved on the outer wall of the rotating rectangular block 56, and then the protective plate 52 is rotated again, so that the protective plate 52 drives the rotating rectangular block 56 to rotate synchronously, so that the rotating rectangular block 56 drives the rotating shaft 55 to rotate synchronously, and The spring 53 is compressed until the rotating rectangular block 56 and the sliding rectangular block 51 are kept in an overlapping state. At this time, the protective plate 52 is pressed downward again, so that the protective plate 52 is sleeved on the sliding rectangular block 51, and the lower surface of the protective plate 52 is fitted with the upper surface of the limiting plate 54. At the same time, the rectangular groove 57 on the protective plate 52 will move from the rotating rectangular block 56 to the sliding rectangular block 51, so that the rotating rectangular block 56 is separated from the limit of the rectangular groove 57. At this time, the elasticity of the spring 53 can drive the rotating shaft 55 to rotate and reset, so that the rotating shaft 55 drives the rotating rectangular block 56 to rotate and reset, so that the rotating rectangular block 56 and the sliding rectangular block 51 are staggered. At this time, the top of the replaced protective plate 52 is limited by the rotating rectangular block 56, and the bottom is limited by the limiting plate 54, so that the protective plate 52 is fixed, thereby completing the replacement of the protective plate 52. By replacing the protective plate 52, the use cost of the plugging plate body 1 can be reduced and the service life of the plugging plate body 1 can be increased.

[0028] When the coal chemical black water impacts the protective plate 52, the protective plate 52 will collapse toward the inside of the plugging plate body 1. At the same time, the protective plate 52 will squeeze the top rod 62, so that the top rod 62 drives the limit block 63 to move to the end away from the protective plate 52, and the limit block 63 stretches the reset spring 64. At this time, the impact force of the coal chemical black water on the protective plate 52 can be converted into the elastic potential energy of the reset spring 64 through the reset spring 64, thereby reducing the impact force of the coal chemical black water on the plugging plate body 1. When the impact force of the coal chemical black water is too large, causing the protective plate 52 to impact When the sliding rectangular block 51 is hit, the sliding rectangular block 51 will collapse toward the inside of the movable groove 4 and compress the energy-absorbing spring 61. At this time, the energy-absorbing spring 61 can be used to absorb the impact force of the sliding rectangular block 51, and the impact force of the sliding rectangular block 51 is converted into the elastic potential energy of the energy-absorbing spring 61, thereby further reducing the impact force of the coal chemical black water on the plugging plate body 1, so that the plugging plate body 1 can be stably installed inside the buffer tank, thereby reducing the impact force of the plugging plate body 1 on the buffer tank and improving the overall service life of the device.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
