[0002] Pneumatic explosion-proof oil pump is a device used to transport high-viscosity materials. It is driven by air pressure to transport high-viscosity materials from one location to another. The explosion-proof design of this device enables it to operate safely in potential explosive environments.

[0003] When using a pneumatic explosion-proof oil pump, generally the suction pipe is inserted into the barrel through the discharge hole on the top of the material barrel. However, if the pneumatic explosion-proof oil pump is directly inserted into the material barrel, the inertia of the pneumatic piston may cause the pneumatic explosion-proof oil pump to shake or even jump during use, which is not safe enough to use. In addition, when the oil pump is in a tilted state, as the weight of the barrel decreases with the gradual reduction of material, the oil pump and the material barrel are prone to tipping over, resulting in material spillage or material contamination, which is not conducive to actual use.

DETAILED DESCRIPTION

[0025] This specific implementation is a pneumatic explosion-proof oil pump for conveying high-viscosity materials with pollution prevention, and its structural schematic diagram is as follows Figure 1-Figure 7 As shown, it includes an annular shell 1 and an oil suction pipe 12. The annular shell 1 is hollow near the middle between the top and the bottom. The annular shell 1 is sleeved on the side wall of the oil suction pipe 12. The bottom of the annular shell 1 is provided with evenly distributed movable openings 6. The inner wall of the movable opening 6 is slidably connected with a rectangular block 5. The bottom of the rectangular block 5 is fixedly connected with a fixing plate 7. The fixing plate 7 is L-shaped. A positioning mechanism is arranged in the annular shell 1. The positioning mechanism is fixedly connected to the rectangular block 5. A height adjustment mechanism is arranged near the right side of the top of the annular shell 1.

[0026] The oil suction pipe 12 in the present technical solution is a pneumatic piston oil pump on the market, which is a relatively mature equipment.

[0027] like Figure 2-Figure 6As shown, the positioning mechanism includes an annular plate 2, which is arranged in the annular shell 1 and is slidably connected to the side wall of the annular shell 1. The top of the annular plate 2 is provided with evenly distributed arc openings 3, which are inclined and arranged in an annular array. A cylindrical block 4 is arranged in the arc opening 3, and the bottom end of the cylindrical block 4 extends to the bottom of the annular plate 2 and is fixedly connected to the top of the rectangular block 5. A fixed screw rod 9 is fixedly connected to the top of the annular plate 2. A fixed opening 10 is opened at the top of the annular shell 1. The top of the fixed screw rod 9 passes through the fixed opening 10 and extends to the top of the annular shell 1. A nut 11 is mounted on the side wall of the fixed screw rod 9, and the bottom of the nut 11 is in contact with the top of the annular shell 1.

[0028] The arc-shaped opening 3 is arranged at an angle, and the inner walls on both sides of the arc-shaped opening 3 are respectively close to the outer side and the inner side of the annular plate 2, so that the annular plate 2 can push the cylindrical block 4 to move outward when rotating, and the nut 11 will squeeze the top of the annular shell 1 when tightened, so that the position of the annular plate 2 can be fixed.

[0029] like Figure 1-Figure 7 As shown, the height adjustment mechanism includes a mounting plate 15, which is fixedly connected to the top of the annular shell 1. A thread hole 18 is opened on one side of the mounting plate 15. A limit screw 17 is installed in the thread hole 18. Both ends of the limit screw 17 extend to the outside of the thread hole 18 respectively. One end of the limit screw 17 is fixedly connected to a knob 19, and the other end is movably connected to a limit block 16. The top of the annular shell 1 is symmetrically and movably connected with a splint 13. The limit block 16 is located between the two splints 13, and the second anti-slip pad 14 is fixedly connected to the opposite sides of the two splints 13.

[0030] The second anti-skid pad 14 is arranged in a corrugated shape, which can better achieve the anti-skid effect. The limit block 16 is relatively close to the annular shell 1, so when the limit screw 17 is rotated, the annular shell 1 will block the limit block 16, so that the limit block 16 will not rotate.

[0031] Among them, the fixed plate 7 is fixedly connected with a first anti-skid pad 8 on one side away from the center of the annular shell 1. The first anti-skid pad 8 is arranged in a wave shape. The wavy first anti-skid pad 8 can improve the anti-skid effect, and the first anti-skid pad 8 is made of rubber material, which can avoid rigid contact with the inner diameter of the material barrel discharge port.

[0032] In addition, the front and rear side walls of the limit block 16 are respectively provided with installation grooves 20, and a pulley 21 is installed between the top and bottom of the inner cavity of the installation groove 20. The pulley 21 is in contact with the clamping plate 13. The pulley 21 can reduce resistance and increase service life.

[0033] Among them, sliders are fixedly connected to both sides of the rectangular block 5, and a sliding groove matching the slider is opened on the inner wall of the movable opening 6. The slider 5 and the sliding groove can support the rectangular block 5 to prevent the rectangular block 5 from detaching from the movable opening 6.

[0034] Working principle: When using this technical solution, if it is necessary to use pneumatic explosion-proof oil pumping to extract and transfer the material in the material barrel, first place the annular shell 1 on the discharge port at the top of the material barrel, so that several fixed plates 7 enter the discharge port, then push the annular plate 2 backwards through the nut 11 to rotate counterclockwise, and the annular plate 2 drives the arc opening 3 to rotate counterclockwise. Because the arc opening 3 is inclined, the arc opening 3 rotates counterclockwise synchronously, so that several cylindrical blocks 4 drive the rectangular blocks 5 and the fixed plates 7 to move outward, so that several fixed plates 7 clamp the inner circle of the discharge port, so as to fix the annular shell 1 on the discharge port of the material barrel, and then tighten the nut 11 to fix the rotation position of the annular plate 2. The oil suction pipe 12 is fixed, which can prevent the fixing plate 7 from loosening. Then the oil suction pipe 12 can be inserted into the center of the annular shell 1 and extended into the material barrel. When the oil suction pipe 12 is inserted into the material barrel to a suitable depth, the limit screw 17 is rotated by the knob 19 to drive the limit block 16 to move to the left, so that the two pulleys 21 push the two clamping plates 13 to swing toward the middle, clamping the oil suction pipe 12. In this way, the position of the oil suction pipe 12 can be fixed, so that the oil suction pipe 12 can be kept in a vertical state, and the annular shell 1 can be fixed at any height on the oil suction pipe 12, thereby improving the flexibility of use. Then, the material in the material barrel can be extracted and transferred, which can effectively solve the problem of easy shaking of the oil suction pipe 12.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
