The utility model discloses a polishing device for wear-resistant flat glaze ceramic tiles, which relates to the technical field of ceramic tile polishing, and comprises a polishing structure, a fixed plate and a rotating shaft rotationally arranged in the fixed plate, the dust collection structure comprises a sealing piece movably connected to the surface of the rotating shaft, a dust collection assembly fixed to the sealing piece, and an auxiliary assembly fixed to the surface of the rotating shaft and located in the sealing piece; the sealing piece comprises a left sealing shell rotating on the surface of the rotating shaft and a right sealing shell rotating on the surface of the rotating shaft. According to the utility model, the dust absorption amount is increased through the dust absorption taper holes, the dust amount in the air around the working environment is reduced, and the dust attached to the surface of the ceramic tile can be reduced, so that the surface quality of the polished ceramic tile is improved, the suspension amount of the dust in the working environment is reduced, and the threat of the dust to the health of operators is reduced.

This utility model provides a lawn mower for landscaping, belonging to the field of landscaping machinery. It includes a rectangular plate with a lifting and trimming mechanism on one side. A dust-reducing component is located on the top of the rectangular plate, and a collection component is located at the bottom of the lifting and trimming mechanism. The lifting and trimming mechanism activates a first motor and a second motor. The first motor drives a rotating rod to rotate, causing a limiting block to move horizontally within a groove. Under the action of a spring, this moves the trimmer shears up and down. The second motor drives a vertical rod and the trimmer shears to rotate, allowing adjustment of the height for lawn trimming. The dust-reducing component activates a water pump, and water flows through a water pipe and hose to a mist cannon. The mist cannon atomizes the water into extremely fine droplets under high pressure, adsorbing dust particles in the air, reducing dust suspension, minimizing the impact of dust on the user's respiratory health, and improving the working environment.

The river and lake bottom mud in-situ remediation device can efficiently complete river and lake bottom mud remediation treatment, and is simple in structure and convenient to operate.

This invention belongs to the field of river and lake sediment remediation technology, and discloses an in-situ electric remediation system for river and lake sediments. The system includes an insulated remediation support frame with multiple openings on the walls of its upper and lower horizontal pipe groups; a pair of anode electrode rods inserted into a pair of opposite pipes in the lower horizontal pipe group; a pair of cathode electrode rods inserted into a pair of opposite pipes in the upper horizontal pipe group; the anode and cathode electrode rods are respectively connected to the positive and negative terminals of a power supply via wires; a remediation material package fixed to the upper horizontal pipe group of the insulated remediation support frame; an insulated positioning rod inserted into a vertical pipe for insertion into the remediated sediment; a rigid force transmission sleeve fitted onto the upper section of the insulated positioning rod; and a traction rope assembly, with one end of each traction rope fixed to the upper horizontal pipe group and the other end wound around a pulley and fixed to a rope shaft. The above system has a simple structure and can effectively remediate river and lake sediments contaminated with heavy metals.

The application discloses a dust separation and filtering device for powder spraying, and relates to the technical field of powder recycling equipment.The device comprises a rectangular outer shell, a swing mechanism for reducing powder residues is arranged in the outer shell, an impact mechanism for accelerating dust separation is further arranged in the outer shell, a flushing mechanism for reducing dust floating is arranged outside the swing mechanism, a sealing mechanism for reducing dust diffusion to the upper part of the outer shell is arranged on the inner wall of the outer shell, a connecting rod is driven by a hydraulic cylinder, hooks on a plurality of rotating rods are inverted and hang filtering bags, and the bottom openings of the filtering bags are fixed on square plates.When the hydraulic cylinder reciprocates, the overall swing of all the filtering bags can be driven, and the state of the traditional filtering bags that are prone to powder accumulation is changed.During the filtering and recycling process, the powder attached to the inside of the filtering bags is forced to fall off through intermittent swing, the large amount of powder residues on the filtering structure is reduced, and the powder recycling rate is improved.

The utility model relates to sodium sulfate processing technical field, concretely is a kind of sodium sulfate evaporation crystallization environmental protection type separator, including main separator, the inside of main separator is equipped with shunt component, shunt component includes the multiple shunt pipes of being set in the inside of main separator, the upper and lower ends of multiple shunt pipes are fixedly installed with baffle, the inner wall of multiple shunt pipes is equipped with the guide component for prompting liquid to form cyclone in shunt pipe inside, and the adjusting component for controlling multiple guide components is arranged on main separator in shunt pipe inside deformation and cleaning its inner wall;By setting guide component and adjusting component, reached the effect that can let sodium sulfate solution form cyclone in shunt pipe, cyclone motion increases the contact area of sodium sulfate solution and pipe wall, while centrifugal force promotes crystallization particle to gather and settle to pipe wall, improves crystallization purity, and can control the effect that helical elastic piece realizes automatic cleaning dirt, maintains heat transfer efficiency.
