This invention relates to the field of sterilization treatment device technology, and discloses a sterilization treatment device for dishwasher water, including a dishwasher and a sterilization lamp installed inside the dishwasher, and further including: a filter section installed on the dishwasher; a backflushing section installed on the filter section; a sterilization section installed on the dishwasher; the filter section includes an installation assembly installed on the dishwasher; a limiting assembly installed on the installation assembly; the installation assembly includes a conveying pipe connected to the dishwasher, and a support ring is provided on the inner wall of the conveying pipe. This invention, by setting up a filter section, solves the problems of existing sterilization treatment devices where the filter screen uses a fixed or entirely enclosed installation structure, mostly requiring auxiliary tools, making operation difficult, and making timely and convenient maintenance difficult after the filter screen becomes clogged. Long-term accumulation of debris can easily cause water circuit blockage, slow water flow, and easily lead to water backflow.

The pipeline dredger is pre-buried in a pipeline and comprises a dredging piece and a connecting line, the dredging piece is of a sheet-shaped structure, a gap is formed in the dredging piece, and the gap extends from inside to outside along a preset path and penetrates through the peripheral face of the dredging piece so that the dredging piece can be divided into at least two structural units which are connected with each other; one end of the connecting line is fixedly connected with the free end of one of the structural units; when pulling force is applied to the connecting line, and the blocking force of the dredging piece by blockages in the pipeline reaches a set value, the structural units relatively displace under the combined action of the pulling force and the blocking force, so that the dredging piece is converted into a three-dimensional unfolding state from a flat folding state. When the connecting line is pulled, an effective contact area can be formed between the connecting line and a blockage object, extrusion and pushing effects are generated, a flat folded state can be converted into a three-dimensional unfolded state, and the problem that a traditional dredging tool is more and more tightly pushed and gets stuck is solved.

The utility model relates to related technical field of coal bunker, and disclose coal bunker automatic cleaning of coal bunker anti -blocking device, including warehouse body, discharge pipe and transmission assembly, the inside of warehouse body is equipped with scraping assembly, the inside of discharge pipe is equipped with anti -blocking subassembly, and scraping assembly and anti -blocking subassembly are connected through transmission assembly, the utility model discloses scraping assembly and anti -blocking subassembly through linkage design, effectively solved the security risk and technical defects of traditional unblocking mode: adopt motor synchronous drive ring -shaped scraper and vibration drill bit, realized the cooperative operation of the automatic scraping of coal sticking to the bunker wall and the broken of discharge port blockage, avoid manual high -risk operation, eccentric wheel drive's anti -blocking subassembly makes the drill bit produce shearing broken effect through high -frequency vibration, and cooperation spring reset mechanism of bellows protection, ensure the efficient dredging of wet coal blockage, and ring -shaped rack transmission structure makes the scraper run smoothly, and the linkage design of anti -blocking subassembly significantly improves the cleaning efficiency, and reduces equipment energy consumption simultaneously.

This utility model relates to a conveying mechanism for an engine valve spring production line, including a platform with a first conveying device and a pushing mechanism on the right side of the platform. This conveying mechanism, through the pushing mechanism, ensures that when engine valve springs are conveyed by the first conveying device and fall onto the drive box, they scatter horizontally. Then, a first hydraulic pushing device pushes these horizontally scattered engine valve springs onto a material conveying box. A material conveying trough then allows the valve springs pushed onto the material conveying box to fall one by one into a storage box on a second conveying device. Finally, a second hydraulic push-pull device effectively unclogs the material conveying trough and, by controlling its extension and retraction, slows down the discharge speed of the valve springs. Therefore, this mechanism is highly practical.

The present application provides a kind of paste pipeline blockage dredging device, including pressure release device, dredging pipe, dredging pipe transport device and passage excavation device;The pressure release device includes the buffer pipe section of tubular hollow structure with the same diameter as the system main pipeline pipe diameter;Its one side outlet is connected with paste pipeline conveying system main pipeline;The dredging pipe has multiple, stacked in dredging pipe transport device;Each dredging pipe includes outer sleeve and spiral inner tube, spiral inner tube is sleeved into outer sleeve, spiral inner tube can rotate in outer sleeve, the dredging pipe transport device is used to store, rotate, push, recycle dredging pipe, also discloses corresponding dredging method;Can be blocked in paste pipeline system, especially hard blocked section is pressure-tight dredged.Avoids the material leakage discharge and environmental pollution problem caused by cutting pipe, has strong adaptability, high flexibility, is easy to use and has strong dredging performance.
