The utility model relates to the technical field of waste gas incinerators, and discloses a full-combustion waste gas incinerator which comprises an incinerator body, a preheating guide plate is fixedly connected to the interior of the incinerator body, a plurality of flame spray guns are fixedly connected to the inner wall, located on the left side of the preheating guide plate, of the incinerator body, and a backflow cover is fixedly connected to the inner wall of the left side of the incinerator body. A heating pipe is fixedly connected into the preheating flow guide plate, the preheating flow guide plate is arranged to be a curved plate, an oxygen conveying pipe is fixedly connected to the inner wall of the left side of the furnace body, and a spiral air conveying pipe is fixedly connected to the pipe wall of the oxygen conveying pipe. The heating pipe provided by the utility model can be used for heating the preheating guide plate and preheating waste gas, so that the temperature of the waste gas is increased, and the oxygenolysis efficiency is improved when the waste gas is contacted with the flame spray gun for combustion.

The utility model discloses medium sand backfill pumping equipment, which relates to the technical field of water treatment, and comprises a mounting plate, a pumping pipe and a guide pipe, the pumping pipe is fixedly arranged in the mounting plate in a penetrating manner, the lower end of the pumping pipe is fixedly connected with a corrugated pipe and is fixedly connected with the guide pipe through the corrugated pipe, and the outer wall of the lower end of the guide pipe is rotatably sleeved with a discharge pipe; a driving mechanism is arranged on the upper surface of the mounting plate, two rotating rods are symmetrically and rotationally arranged on the outer wall of the pumping pipe, the rod walls of the two rotating rods are fixedly sleeved with first gears, and U-shaped rods are fixedly arranged on the surfaces of the two first gears. By means of the corrugated pipe fixedly arranged between the pumping pipe and the guiding pipe, normal swinging of the guiding pipe can be guaranteed, medium sand guided out of the discharging pipe can be laid in a large range in the swinging process of the guiding pipe, the working efficiency is guaranteed, and meanwhile the follow-up working intensity of workers is lowered.

According to the connecting structure for the air cylinder of the tipping paper lifting device of the tipping machine, a U-shaped block with an opening facing a connecting rod is fixed to one end of the air cylinder, the end of the connecting rod is located in a groove of the U-shaped block, and a pin shaft sequentially penetrates through through holes in the U-shaped block and the connecting rod and is matched with a cotter pin at the end of the pin shaft through a gasket arranged at one end of the pin shaft in a sleeving mode for limiting; and the other end of the air cylinder is connected with a combined support column which is detachably fixed on a wall plate of the assembling machine. By optimizing the connecting structure of the air cylinder of the paper lifter, the problems of high disassembly and assembly difficulty and low efficiency caused by the fact that a traditional air cylinder connecting structure adopts an elastic check ring for a shaft for positioning are solved, and the quick disassembly and assembly requirement of the air cylinder of the paper lifter in a narrow gap between a gluing assembly and a wall plate of an assembling machine is met; rapid separation of the air cylinder, the combined supporting column and the pin shaft is achieved, the difficulty of disassembling and assembling the air cylinder is reduced, the replacement time is shortened, and the efficiency and quality of replacing the air cylinder are improved.
