The inner liner is connected to the through hole on the steel barrel cover through a docking joint and locked with a locking nut, so that the inner liner is detachably connected to the steel barrel wall and the steel barrel cover, so that it can be replaced on site.

[0004] However, the steel barrel cover of the above-mentioned device is stuck on the steel barrel wall. Since the inner liner is fixed to the steel barrel cover, the connection between the steel barrel cover and the inner liner as a whole and the steel barrel wall is poor. When the steel-plastic composite barrel is shaken, the liquid inside the inner liner can easily drive the inner liner and the steel barrel cover to fall off the steel barrel wall. After the inner liner is thrown out, it collides with the outside and breaks, causing leakage, which poses certain safety hazards. Therefore, a steel-plastic composite barrel is needed that can improve the connection between the replaceable inner liner and the steel barrel wall to prevent the steel barrel from shaking and the inner liner from being thrown out of the steel barrel.

[0026] Embodiment 1

[0027] Figure 1-Figure 3 One embodiment of the utility model is a steel-plastic composite barrel with a replaceable liner, comprising a steel barrel wall 1, an inner liner 2 being slidably connected to the inner wall of the steel barrel wall 1, a steel barrel cover 3 having one end movably extending to the inside of the steel barrel wall 1 being arranged on the top of the steel barrel wall 1, a limiting component 4 for fixing the steel barrel cover 3 being installed inside the steel barrel wall 1, when assembling the steel-plastic composite barrel, the inner liner 2 is first placed inside the steel barrel wall 1, and then the limiting component 4 is slid downward along the inner wall of the steel barrel wall 1 until the bottom of the limiting component 4 is pressed against the inner liner 2, the limiting component 4 is fixed on the steel barrel wall 1, and then the steel barrel cover 3 is covered on the top of the steel barrel wall 1, and the steel barrel cover 3 and the limiting component are rotated. 4 is clamped and fixed to realize the fixation of the replaceable inner liner 2, the steel drum cover 3 and the steel drum wall 1. When the inner liner 2 needs to be replaced, the steel drum cover 3 is first rotated to disengage the steel drum cover 3 from the inside of the limiting component 4, and then the steel drum cover 3 is moved away from the steel drum wall 1, and the limiting component 4 is removed from the inner wall of the steel drum wall 1. Finally, the inner liner 2 is taken out from the inside of the steel drum wall 1, and the new inner liner 2 is placed in the steel drum wall 1, and the limiting component 4 and the steel drum cover 3 are reinstalled. The limiting component 4 can be used to fix the inner liner 2 and the steel drum cover 3 to the steel drum wall 1, thereby improving the firmness of the connection between the replaceable inner liner and the steel drum wall and preventing the steel drum from shaking and the inner liner from being thrown out of the steel drum.

[0028] The limiting assembly 4 includes a limiting ring 41 which is slidably connected to the inner wall of the steel barrel wall 1. The inner wall of the limiting ring 41 is provided with a plurality of first bolts 42 which movably penetrate the limiting ring 41 at one end. The inner wall of the limiting ring 41 is fixedly connected with a plurality of limiting frames 43. The bottom of the steel barrel cover 3 is fixedly connected with a plurality of blocking blocks 44 which are adapted to the limiting frames 43. When the liner 2 is installed into the steel barrel wall 1, the limiting ring 41 is slid downward along the inner wall of the steel barrel wall 1 until the bottom of the limiting ring 41 is pressed against the liner 2, and then the first bolt 42 is rotated. After the first bolt 42 squeezes the inner wall of the steel barrel wall 1, the limiting ring 41 is fixed to the steel barrel wall 1, and then the blocking block 44 at the bottom of the steel barrel cover 3 is moved between the two limiting frames 43, and the steel barrel cover 3 is covered on the top of the steel barrel wall 1. At this time, the blocking block 44 is between the two limiting frames 43, and the steel barrel cover 3 is rotated. The steel drum cover 3 drives the blocking block 44 to enter the limit frame 43. At this time, the top and bottom of the blocking block 44 are blocked and fixed by the limit frame 43 and the inner liner 2 respectively, completing the fixation of the replaceable inner liner 2 and the steel drum cover 3. When the inner liner needs to be replaced, first rotate the steel drum cover 3, and the steel drum cover 3 drives the blocking block 44 to move between the two limit frames 43, and then move the steel drum cover 3 upward, and the steel drum cover 3 drives the blocking block 44 to move upward from between the two limit frames 43. Finally, the steel drum cover 3 is moved away from the steel drum wall 1, and the first bolt 42 is rotated to no longer squeeze the inner wall of the steel drum wall 1. The limiting ring 41 is slid upward along the inner wall of the steel drum wall 1 until the limiting ring 41 moves to the outside of the steel drum wall 1. Finally, the inner liner is removed from the inside of the steel drum wall 1, and the new inner liner 2 is installed inside the steel drum wall 1 in the same way, completing the inner liner replacement process.

[0029] A plurality of arc grooves are provided on the outer side of the steel drum cover 3, and a second bolt 5 with one end movably extending to the inside of the steel drum cover 3 is provided on one side of the inner wall of the arc groove. When the steel drum cover 3 is put on the top of the steel drum wall 1 and fixed with the limiting component 4, the second bolt 5 is rotated until the second bolt 5 passes through the steel drum cover 3 and presses against the steel drum wall 1, so that the steel drum cover 3 is fixed by the limiting component 4 and the second bolt 5 from different positions, thereby improving the firmness of the steel drum cover 3.

[0030] The top of the inner liner 2 is connected to a docking tube 6, and the top of the steel drum cover 3 is connected to an outer tube 7 for wrapping the docking tube 6. The top of the outer tube 7 is provided with a cover plate 8 with one end movably extending into the interior thereof. When the inner liner 2 and the steel drum cover 3 are installed on the steel drum wall 1, the cover plate 8 is opened, and the liquid is poured into the outer tube 7. The liquid flows into the inner liner 2 along the outer tube 7 and the docking tube 6 until the liquid capacity inside the inner liner 2 reaches the requirement, and then the pouring of liquid into the outer tube 7 is stopped. Finally, the cover plate 8 is covered on the top of the outer tube 7, which can conveniently complete the purpose of adding liquid to the inner liner 2.

[0031] Embodiment 2

[0032] Reference Figure 1-Figure 5On the basis of the first embodiment, an extension tube 9 having one end movably extending into the interior thereof is provided at the top of the butt joint tube 6, and a clamping assembly 10 for fixing the extension tube 9 is installed inside the outer tube 7, and the clamping assembly 10 includes a protrusion 101 fixedly connected to the inner wall of the outer tube 7, an outer frame 102 is sleeved on the outside of the protrusion 101, and a spring 103 is fixedly connected between one side of the inner wall of the outer frame 102 and the protrusion 101, a groove matching the outer frame 102 is provided on the outer side of the extension tube 9, a metal sheet 11 corresponding to the outer frame 102 is fixedly connected to the inner wall of the extension tube 9, and a magnet block 12 having one end movably extending into the interior thereof is provided on one side of the outer frame 102 close to the metal sheet 11, and a plurality of tilting blocks 13 are fixedly connected to the inner wall of the extension tube 9, and the metal sheet 11 is installed at the bottom of the tilting block 13 , the spring 103 pulls the outer frame 102 close to the protrusion 101 due to its own elastic force. When the inner liner 2 and the steel drum cover 3 are installed on the steel drum wall 1, the staff's hand passes through the outer tube 7 and extends into the extension tube 9, and then pulls the tilting block 13 to drive the extension tube 9 to rise until the groove on the extension tube 9 moves to the outer frame 102. The magnetic force between the magnet block 12 and the metal sheet 11 attracts the outer frame 102 to move toward the extension tube 9 until the outer frame 102 passes through the groove and enters the extension tube 9. At this time, the extension tube 9 is fixed by the outer frame 102 and cannot move. It can automatically dock and fix with the outer tube 7 when the extension tube 9 moves to the specified position, which facilitates the docking of the pipe on the steel drum cover 3 with the pipe on the inner liner 2, and can reduce the possibility of liquid leakage caused by loosening of the pipe connection between the pipe on the steel drum cover 3 and the inner liner 2.

[0033] When it is necessary to disconnect the connection between the steel barrel cover 3 and the inner liner 2, the staff inserts his fingers into the outer tube 7, and then presses the outer frame 102 toward the outside of the extension tube 9 until the outer frame 102 moves to the outside of the extension tube 9. At this time, the extension tube 9 slides downward due to its own gravity, and the metal sheet 11 moves away from the magnet block 12 as the extension tube 9 descends. After the attraction between the magnet block 12 and the metal sheet 11 decreases, the spring 103 pulls the outer frame 102 toward the protrusion 101 due to its own elastic force.
