The invention discloses an anti-seismic full-automatic deslagging biogas tank. A deslagging chamber, a filter chamber and a hydraulic pressure chamber are sequentially arranged above the top of a fermenting tank; a first filter plate is arranged between the adjacent deslagging chamber and filter chamber, a second filter plate is arranged between the adjacent filter chamber and hydraulic pressure chamber, and the diameter of a filter hole of the first filter plate is longer than that of the filter hole of the second filter plate; the fermenting tank is internally provided with an anti-seismic beam; the anti-seismic beam comprises a main beam and auxiliary beams; and two pairs of the auxiliary beams are arranged. According to the anti-seismic full-automatic deslagging biogas tank, old biogas slag is discharged from a deslagging pipe in a biogas generating process, the discharged biogas slag enters the deslagging chamber, solid biogas slag included in the biogas slag is filtered through filter screens positioned on two side walls of the filter chamber, and a biogas slurry flows into the hydraulic pressure chamber, in such a way, and generated biogas is capable of conveniently ascending to a gas storage chamber positioned at the upper part of the fermenting tank and is 30% more than the gas output of the traditional biogas tank. The anti-seismic full-automatic deslagging biogas tank disclosed by the invention has good seismic resistance, thereby being suitable for districts such as mountain districts, geologic active districts and seismically active districts.

The invention belongs to the technical field of drilling tools, and specifically discloses a pistol drill facilitating accurate location. The pistol drill facilitating accurate location comprises a machine body and a drill bit, wherein three slide rods are arranged in the circumferential direction of the machine body; a sealed accommodating shell is arranged in the circumferential direction of themachine body; first piston barrels and a second piston barrel are arranged in the accommodating shell; the capacity of the second piston barrel is equal to the sum of the capacities of all the firstpiston barrels; a first piston is arranged in each first piston barrel; each first piston is fixedly connected with the corresponding slide rod; an intake pipe is communicated to each first piston barrel; all the intake pipes communicate with the second piston barrel; a second piston is arranged in the second piston barrel; a piston rod is arranged on the second piston; an induction mechanism is further arranged in the accommodating shell; the induction mechanism comprises a positive plate and a negative plate; the positive plate is fixedly connected with the piston rod; and the distance between the positive plate and the negative plate is equal to the length of the second piston barrel. According to the scheme, the problem that the drill bit is liable to be inserted slantwise into a workpiece during the drilling of operating personnel, is solved.
