The utility model relates to cup brush technical field especially is a cup brush, including the pole body, the inside of pole body is provided with the accommodation cavity, and the end of pole body is provided with locking structure, sponge brush, the sponge brush is fixed at the end position of pole body through locking structure, sleeve piece, sleeve piece is slidably arranged on the outside of pole body, and the extrusion cleaning of sponge brush is realized along the axial sliding of pole body, the utility model discloses a combination of the sleeve piece of push -pull and sponge brush, has realized the convenient cleaning of sponge brush, just needs to simply push -and -pull sleeve piece, can extrude the sponge brush of multiple, high -efficient and thus extrudes the sewage and dirt in its inside fast, avoids the step of needing to use hand direct contact and extrusion dirty sponge brush in traditional mode, and the operation is extremely simple and labor saving, and guarantees the health of use process, prevents the hand of user from being contaminated.

The invention discloses low-temperature heat energy exchange energy-saving equipment, and belongs to the technical field of low-temperature heat energy exchange, and the equipment comprises a raw water pipe which is used for circulation of raw water in a chemical water system and is made of an elastic material; the circulating water pipe is sleeved outside the raw water pipe, and a space for circulating water in the factory to circulate is formed between the inner wall of the circulating water pipe and the outer wall of the raw water pipe; wherein the outer wall of the raw water pipe is connected with the inner wall of the circulating water pipe through a supporting assembly, a'two-way reverse flow 'flow field is constructed through multi-layer tiny spiral trickle in the pipe and spiral turbulent flow outside the pipe, the heat exchange specific surface area is greatly increased, a laminar flow boundary layer is destroyed, and the low-temperature heat energy recovery efficiency is improved in a limited space; the elastic assembly is impacted by fluid, kinetic energy of the fluid is converted into high-frequency micro-vibration of the pipe wall, the problem of scaling and pollution blockage caused by poor circulating water quality is solved by matching with the centrifugal scouring effect of spiral flow, and long-term, stable and efficient operation of equipment is ensured.

The invention discloses an explosion-proof device for an underground coal mine. The explosion-proof device comprises a base; the suction device comprises a suction cylinder mounted on the base, a column frame is mounted on the suction cylinder, and an adsorption device is further arranged in the column frame; the early warning device comprises a plurality of side shell covers and an elliptical filter cylinder, the side shell covers are distributed along the circumference of the outer side of the column frame, opposite outer filter holes and inner filter holes are distributed in the cylinder wall of the elliptical filter cylinder, the inner filter holes are covered with the side shell covers, suction ports used for communicating the column frame with the inner filter holes are formed in the side shell covers, and a mist spray pipe is arranged at the axis of the elliptical filter cylinder; a cleaning mechanism is arranged on the mist spraying pipe, a monitoring box used for collecting pulverized coal is arranged at the lower end of the side shell cover, a liquid inlet pipe connected with the mist spraying pipe is arranged in the monitoring box, the accuracy and reliability of abnormal judgment of the coal dust concentration are improved, and concentration monitoring and trend early warning are achieved.
