This invention relates to the technical field of emulsion explosive packaging, and more particularly to a processing device for emulsion explosives. A feeding pipe is located in the middle of the machine body, connecting to an external feeding device. A mounting plate is fixedly connected to the top of the machine body, and a cylindrical block is located at the bottom of the mounting plate. The lower end of the feeding pipe passes through the cylindrical block. Symmetrical sliding blocks are provided on the mounting plate, and clamping arc blocks are slidably connected to the sliding blocks. A bidirectional threaded rod is rotatably connected to the mounting plate, and the bidirectional threaded rod is threadedly connected to the sliding blocks. A dual-axis motor is mounted on the mounting plate, and the dual-axis motor is connected to the bidirectional threaded rod. This solution effectively solves the problem of powder splashing and scattering during existing powder bagging processes, ensuring the health of operators and meeting industrial production safety and environmental protection requirements. The dual-axis motor and bidirectional threaded rod drive the clamping arc blocks to clamp the pre-made bag opening, and in conjunction with a piston rod and air cylinder, inflates the airbag block, sealing the gap between the bag opening and the cylindrical block.

The utility model relates to the technical field of waste gas treatment, in particular to light-oxygen catalysis VOC (volatile organic compound) waste gas treatment equipment. The technical problems that a filtering device is damaged when high-heat waste gas is treated for a long time, the service life of waste gas collecting equipment is shortened, the filtering effect of the filtering device is poor due to long-time use, and water vapor generated under the action of light oxygen cannot be discharged out of an instrument are solved. According to the technical scheme, the light-oxygen catalysis VOC waste gas collecting equipment comprises a shell assembly; the device further comprises a cooling assembly, a collecting assembly, a light source assembly, a filtering assembly and a detecting assembly. Internal gas is subjected to an oxidation reaction through an ultraviolet lamp tube, generated water vapor flows into the collecting assembly through flow holes of a fourth fixing plate, the problem that water is accumulated in the instrument under light-oxygen catalysis is solved, the interior of the cooling assembly can be cooled through a liquid nitrogen generator device, and the water vapor can flow into the collecting assembly through the flow holes of the fourth fixing plate. VOC waste gas is converted into volatile liquid, and the volatile liquid is discharged through a collecting device.

The invention relates to the technical field of tunnels in water conservancy and hydropower engineering, in particular to a landslide repairing structure and method for a built pressure tunnel with a ventilation pipe arranged in a mountain, the landslide repairing structure comprises the built pressure tunnel, an anchoring and shotcreting supporting structure and a ventilation structure, and the built pressure tunnel comprises a conventional tunnel section, a bare rock landslide section and landslide rock ballast; the anchor-shotcrete supporting structure comprises primary shotcrete, a reinforcing mesh, shotcrete, a system anchor rod and a random drainage hole, and safety and stability of collapse section supporting are guaranteed. The ventilation structure comprises a ventilation pipe, a pipe cap, a hole wall and lining concrete; the collapse repairing workload is small, construction is easy and convenient, the investment cost is saved, the construction period is shortened, air in the cavity of the top of the collapse section can be exhausted along the ventilation structure when water is introduced into the main hole after collapse repairing, guarantee is provided for safe operation of the tunnel, and the method has the advantages of being easy and convenient to construct, short in construction period, safe, reliable and low in investment. And the timely repair of the collapse of the built pressure hydraulic tunnel can be met.

The utility model belongs to the technical field of high-platform silica sol ball valves, and particularly relates to a high-platform silica sol ball valve which comprises a ball valve body and a fixing plate, the fixing plate is fixedly connected to the ball valve body, a valve handle is rotationally connected to the ball valve body, and one end of the valve handle penetrates through the fixing plate, extends to the outside and is rotationally connected with the fixing plate. The first sliding groove is formed in the fixing plate, an insertion block is connected into the first sliding groove in a sliding mode, and one end of the insertion block penetrates through the valve handle and extends into the valve handle to be matched with the valve handle in an inserted connection mode. The silica sol high-platform ball valve solves the problem that after the silica sol high-platform ball valve is used, part of liquid is left in a ball core groove in the silica sol high-platform ball valve and cannot be discharged; the problem that when a user dismantles a pipeline and overhauls the silica sol high platform ball valve, the user possibly touches a valve handle on the silica sol high platform ball valve by mistake under the inattention condition to open the closed silica sol high platform ball valve, and water source waste is caused is solved.

The invention discloses a circulating type edible mushroom processing and crushing device, and relates to the technical field of edible mushroom processing equipment.The circulating type edible mushroom processing and crushing device comprises a machine case, a feeding port is formed in the upper end of the machine case, a discharging port is formed in the lower end of the machine case, inner ring grooves are formed in the two end faces of the interior of the machine case, and a filter cartridge with multiple sets of filter holes is rotationally connected between the two inner ring grooves; arc-shaped side blocks are arranged at the positions, located on the two sides of the lower end of the filter cartridge, in the machine box, and a switching assembly used for switching the positions of filter holes of the filter cartridge is arranged on the machine box. According to the invention, through the arrangement of the anti-blocking assembly, filter holes of the filter cartridge can be backflushed by using high-pressure gas during use, so that fragments clamped in the filter holes can be flushed out, and part of the flushed fragments are in contact with the crushing blades again for further cutting and crushing; and the other part is circulated to the upper part to be cut and crushed again under the action of the circulating shifting piece, so that the problem that the edible mushroom fragments are clamped in the filter holes and cannot be discharged in the prior art can be effectively solved.
