This utility model belongs to the field of cast and rolled plate production technology, and in particular relates to a device for treating soot on the surface of cast and rolled plates. It includes a cleaning mechanism located on one side of the roll, comprising a mounting block and a tilting block. The tilting block is located inside the mounting block, and its upper and lower ends are rotatably connected to a slider via rotating shafts. A cleaning component is mounted on the tilting block, and a rocker arm is hinged to the end of the tilting block away from the rotating shaft. One end of the rocker arm is hinged to the mounting block. A first cylinder is mounted on the mounting block, and its first piston rod is hinged to the tilting block. The first cylinder can retract and fold the tilting block inside the mounting block, and can also extend and tilt the tilting block outwards, causing the cleaning component to be tightly attached to the surface of the roll. This cleaning mechanism can be replaced online, avoiding secondary contamination caused by prolonged contact of the cleaning component with the roll, thus improving cleaning efficiency.

The utility model discloses a polystyrene devolatilization device observation sight glass lower surface anti-adhesion structure which comprises a devolatilization device body, a butterfly valve assembly is installed at the upper end of the devolatilization device body, the butterfly valve assembly comprises a flange, the upper end of the flange is fixedly connected with a seamless steel pipe, a butterfly valve is installed in the seamless steel pipe, and the flange is fixedly connected with the flange. After the improvement that the butterfly valve is additionally arranged between the devolatilization device body and the sight glass, the observation time is short, and the butterfly valve is in a closed state for a long time, so that the time that the lower surface of the sight glass is shielded by high-temperature melt floating up from the inside of equipment is greatly prolonged; long-term observation requirements can be met; besides, under the condition that the sealing effect of the valve element of the butterfly valve is very good, the sight glass of the styrene device can be replaced and cleaned on line even under the condition that a vacuum system is not affected, and therefore long-term stable operation of the production device is guaranteed.

The utility model relates to a biochemical pool on -line replacement aeration system of water pollution treatment, including a plurality of interval settings aeration hose along the pool body width direction, the left end of aeration hose is connected with the branch pipe of supplying air and has detachably connected, the upper end of branch pipe of supplying air is detachably connected with the main pipe of supplying air, its characterized in that: on -line replacement aeration system still includes the hose support for setting in the aeration pool pool body downside, the bottom of hose support and the bottom interval of aeration pool pool body set up, the fixed support column of having on hose support, the upper end of support column is connected in the pool top support of aeration pool pool body upper end, the hose support is provided with the hose limiting group corresponding setting of aeration hose, every hose limiting group all includes a plurality of interval settings hose limiter along the left and right direction, and the hose limiter has the hose limiting portion that corresponding aeration hose moves along the left and right direction and wears, the utility model provides a kind of on -line replacement aeration system that can complete aeration hose replacement without pool body water release.

The utility model provides a kind of electrostatic precipitator flue dust pretreatment device, comprising: first filter frame, the inner side of first filter frame is fixedly installed with bulkhead.The utility model provides a kind of electrostatic precipitator flue dust pretreatment device, by first filter frame, bulkhead, mounting groove, sliding slot, elastic member, baffle, push plate and two filter assemblies etc. structure mutual cooperation, when using, the online replacement of filter assembly is realized, when the filter cotton in one of filter assemblies needs to be replaced, pull the filter assembly, elastic member pushes baffle and push plate, baffle will block through groove, gas can pass through another filter assembly at this time, ensure that equipment continues to run, when filter assembly is installed, it is inserted and push plate is pushed to make baffle move, let gas pass smoothly, this design avoids to stop equipment operation due to replacement filter, effectively reduces the influence on production, reduces enterprise production cost.

The utility model discloses an online film replacing device for emulsion explosive production belongs to packing machine film replacing technical field, and its technical key points include frame, two feeding assemblies are symmetrically arranged on the frame, and the frame between two feeding assemblies is equipped with the guide baffle, a plurality of guide rollers are equipped on the frame below the feeding assembly, the frame below the guide roller is equipped with the temporary storage subassembly, the frame on the one side of temporary storage subassembly is equipped with the discharge roller who cooperates with the subsequent packing equipment, the sensor for detecting the film roll is equipped at the feeding assembly, two film cutting assemblies are equipped on the frame between the feeding assembly and the guide roller, and two film cutting assemblies are symmetrically arranged on both sides of the guide baffle, the hot melting assembly is equipped on the frame between the film cutting assembly and the guide roller, the utility model aims at providing a kind of online film replacing device for emulsion explosive production with simple structure, online replacement, for emulsion explosive packing machine online film replacing.

The application relates to the technical field of sewage treatment, and discloses a biological filter rotating disc system based on replaceable composite fillers and a nitrogen and phosphorus removal method. 2+ The biological filter rotating disc system supports online filler replacement and is suitable for upgrading and reconstruction of sewage plants and advanced treatment of industrial wastewater.

The utility model relates to waste gas recovery treatment technical field especially relates to waste gas recovery treatment device of mesh coating production line. Including support, support is equipped with two, two support respectively is provided with one adsorption bin, one three -way pipe is communicated respectively between the same side end of both sides adsorption bin, three -way ball valve is installed in three -way pipe all, adsorption bin is separatedly provided with multiple sets of guide plate, and sliding has the storage frame between two guide plates opposite up and down, and the built -in adsorption block of storage frame. Adopt modular adsorption structure and double adsorption bin design, through setting up storage frame and sliding type baffle, and cooperate guide plate to realize modular adsorption block's installation and quick replacement, this structure can complete the replacement of partial adsorption module under the prerequisite of not interrupting system operation, simultaneously, double adsorption bin and three -way ball valve linkage control, can according to actual working condition flexible switching one -sided or double -sided adsorption bin operation, realizes the on -line replacement of adsorption material, guarantees the sustained stable operation of device.
