The invention discloses a formula and a preparation process of a carbon ceramic product capable of generating a super-strong far-red line, and belongs to the technical field of carbon ceramic products. The preparation method disclosed by the invention is simple and efficient, the prepared carbon ceramic product not only has super-strong far infrared emission performance, but also shows excellent alkali resistance, wear resistance, oil resistance, corrosion resistance and collision resistance, and meanwhile, the natural environment is not damaged and water and soil loss is not caused in the production process of the product; and the paint is environment-friendly and safe in use, harmless to human bodies and wide in application range.

The utility model relates to the technical field of planting boxes, and discloses a seedling planting box with controllable watering quantity, which is characterized in that a water storage cavity is arranged in a cultivation base, a planting box seat is embedded and mounted on the opening side of the upper part of the water storage cavity, and a plurality of planting cup seats are inserted and mounted in the planting box seat; the capillary water guide rope is arranged on the lower portion of the planting cup base and droops into the water storage cavity, a capillary type plant watering mode is adopted, the capillary water guide rope is arranged at the bottom of the planting cup base, water in the water storage cavity is sucked through the capillary water absorption effect of the capillary water guide rope, water supply is stable, and the lasting time is long. According to the planting box, plant absorption is facilitated, a plant soil layer can be prevented from being scoured, water loss cannot be caused in the absorption process, accurate control over the watering amount can be achieved, the independent planting cup base is adopted, the planting cup base is installed in the planting box base in an embedded and inserted mode, independent taking and moving can be carried out, and the planting box base is convenient to use. The use is flexible, and transplanting of plants is facilitated.

The utility model provides a high-purity copper target material smelting and purifying device, which relates to the technical field of high-purity copper target material smelting and purifying, and comprises a smelting furnace body and a feeding box, a discharge port of the feeding box is provided with a screw feeder, and a discharge port of the screw feeder is provided with a feed pipe communicated with a furnace cover of the smelting furnace body. The feeding box is arranged in the feeding box and used for conveying the target materials, the piston plate is arranged in the feeding box, the target materials in the feeding box move towards the opened opening and closing plate under the action of gravity to enter the spiral feeding machine, and at the moment, part of heat in the smelting furnace body enters the feeding box, but cannot leak from a box opening of the feeding box; after the target material in the feeding box is discharged, the piston plate moves in the feeding box, heat in the feeding box can be extruded out of the feeding box along the opened opening and closing plate and enters the smelting furnace body again, then the opening and closing plate is closed again, the piston plate is reset, the feeding box is reset, and heat loss of the smelting furnace body cannot be caused in the process.

The utility model belongs to the technical field of sedimentation tanks, and particularly relates to a multi-stage sedimentation tank which comprises a sedimentation tank body, and a first filter screen and a second filter screen are respectively and fixedly connected in the sedimentation tank body; a water outlet is fixedly connected to the lower part of the sedimentation tank body; a garbage cleaning assembly is arranged above the position, corresponding to the first filter screen, in the sedimentation tank body, and the garbage cleaning assembly comprises a push plate and a collection box; a sludge cleaning assembly is arranged at the position, corresponding to the second filter screen, in the sedimentation tank body, and the sludge cleaning assembly comprises a first scraper and an auger blade; when sewage is discharged into the sedimentation tank body, the sewage can pass through a first filter screen, garbage in the sewage can be filtered by the first filter screen and is left above the first filter screen, and the garbage can be driven to move and enter a collection box in the rotating process of a push plate, so that the garbage is collected, and subsequent cleaning is not needed; no extra work content is added, and meanwhile, the loss of sewage is not caused.
