The utility model discloses a linen fiber pickling device which comprises a pickling tank, a rolling wheel is rotationally installed in the pickling tank, a partition plate is fixedly installed in the pickling tank, a recycling cavity is formed in the pickling tank, a second extrusion roller is driven to move downwards through arrangement of a downward pressing assembly, and under cooperation with a first extrusion roller, the second extrusion roller is driven to move downwards; the linen fibers are extruded, redundant pickling solution in the linen fibers is extruded out and falls into the recovery cavity, subsequent drying treatment of the linen fibers is facilitated, the pickling solution in the recovery cavity enters the connecting pipe through the arrangement of the recovery assembly and is input into the pickling tank again, recycling of the pickling solution is completed, waste of the pickling solution is reduced, and the environment is protected. Through the arrangement of the pushing assembly, the threaded block moves, then the pushing plate is driven to move slowly, the pushing plate pushes impurities deposited at the bottom into the sewage draining exit and falls into the filter frame, the impurities in the pickling tank are reduced, and pickling of linen fibers next time is facilitated.

The application discloses an energy-saving and environment-friendly steel pipe pickling equipment, which comprises a pickling tank, a track for supporting and conveying steel pipes is arranged in the pickling tank, the track comprises a vertical section and an inclined section, the vertical section is arranged at one side of the pickling tank and a feeding port is formed at the top end of the vertical section, a hoist for lifting the steel pipes to a discharging port is arranged at one end of the low part of the inclined section in the pickling tank, a deceleration block is vertically and slidably connected to the bottom wall of the inclined section, the part of the deceleration block protruding from the bottom wall of the inclined section is an arc surface, a stirring impeller is rotatably connected to the pickling tank, a linkage rod extends from the deceleration block, a transmission assembly for transmitting the linkage rod and the stirring impeller is arranged between the linkage rod and the stirring impeller, the linkage rod vertically moves to drive the stirring impeller to rotate, the continuity of the pickling of a large number of steel pipes is realized, the pickling efficiency is high, the rolling of the steel pipes synchronously realizes the stirring of the pickling liquid in the pickling tank, no additional driving source is needed, the equipment is more energy-saving, the smell in the pickling tank is not easy to spread out, and the equipment is safer and more environment-friendly.

The utility model relates to radish processing technical field discloses a kind of slicing device for radish pickling, including discharging bin, the inner wall of discharging bin is fixedly connected with support plate, the support plate is provided with two, two The transmission connection of the end of the mutual approach of support plate has pivot, the surface transmission connection of pivot has feeding belt, the surface fixed connection of feeding belt has feeding plate, the feeding plate is provided with several, two The right end fixed connection of support plate has baffle one, the baffle one is provided with two.The utility model passes through the radish is placed into discharging bin, radish falls on feeding belt by the clearance between support plate. Feeding belt is obliquely placed on support frame surface, this design not only improves feeding efficiency, but also can ensure that radish does not slip in conveying process, external motor drives feeding belt movement by pivot, feeding plate is conveyed to slicing area from discharging bin with radish. Baffle one and baffle two ensure that radish does not fall in conveying process.

The quartz sand pickling equipment comprises a reaction kettle and a mother liquor tank, a feeding hole is formed in the top of the reaction kettle, an acid inlet and a second acid discharge hole are respectively formed in the bottom of the reaction kettle, and a sand discharge hole is formed in the side surface of the reaction kettle; a first liquid inlet and a second liquid inlet are formed in the top of the mother liquid tank, the first liquid inlet is connected with the second acid discharge port through a pipeline, the second liquid inlet is connected with an outlet of an acid pump through a pipeline, and an inlet of the acid pump is connected with an acid supplementing tank; a liquid outlet is formed in the bottom of the mother liquid tank and is connected with the acid inlet through a pipeline; an ion concentration detection device is fixedly mounted in the mother liquor tank and is connected with a concentrator through a signal line, the concentrator is connected with a signal converter, and the signal converter is connected with a computer; and valves are arranged at the second acid discharge port, the sand discharge port and the liquid outlet. The device not only realizes the recycling of the pickling waste liquid, but also improves the quality of quartz sand.

The invention relates to the technical field of copper-clad ceramic substrate processing, in particular to a method for solving poor insulativity between DCB copper islands. Comprising the following process: placing a DCB ceramic substrate with poor insulativity after pattern transfer in an oxygen-containing atmosphere or a non-oxygen-containing atmosphere for processing to obtain a finished product. The method has the beneficial effects that the method is a remedial treatment method for confirming a product with poor insulation, treatment under an oxygen-containing atmosphere or treatment under a non-oxygen-containing atmosphere is added to a DCB ceramic substrate with poor insulation after pattern transfer, and conductive components in an interface product and by-products after decomposition of the conductive components are effectively removed; the resistivity of the DCB copper island is increased, the insulativity is enhanced, and overlarge leakage current generated when high voltage is applied between the islands is avoided.
