The application relates to the technical field of pathological waste wax recycling, and provides a regenerating device for recycling pathological waste wax, which comprises a crushing bin, a sedimentation bin, a centrifugal bin, a forming bin and an overflow pipe. Waste wax powder formed by the crushing bin falls into the sedimentation bin to form wax liquid. The bottom surface of the sedimentation bin is arranged in an inclined mode. One end of the overflow pipe is located in the sedimentation bin to discharge the wax liquid into a centrifuge in the centrifugal bin for secondary separation, and then the wax liquid enters the forming bin to form solid paraffin. The waste wax powder formed by the crushing bin falls into the sedimentation bin. Since the volume of the waste wax powder is small, the waste wax powder is easy to melt and cannot easily disturb the solid impurities at the bottom of the sedimentation bin. The wax liquid in the sedimentation bin can be coarsely filtered, and the wax liquid can be finely filtered by the centrifugal bin. Compared with single filter screen filtering, the device can effectively avoid the blockage of the filtering equipment, and greatly improve the recycling efficiency and quality.

The utility model discloses a bottle feeding adjusting baffle which comprises a baffle body. The section of the sliding rod is polygonal, the top of the sliding rod is provided with a plane, and the sliding rod is arranged at the top of the storage bin and located above the baffle body; the sliding sleeve is slidably arranged outside the sliding rod in a sleeving mode, and inner side faces matched with all the outer side faces of the sliding rod are arranged in the sliding sleeve; one end of the connecting plate is connected with the baffle body, and the other end is connected with the sliding sleeve; and the bolt is spirally arranged at the top of the sliding sleeve, penetrates downwards from the top of the sliding sleeve and abuts against the top surface of the sliding rod. The sliding sleeve is sleeved with the sliding rod, force acting on the baffle body is converted into torsional force between the sliding sleeve and the sliding rod, due to the fact that the section of the sliding rod is polygonal, the torsional force is counteracted by the sliding rod, the force finally transmitted to the bolt is reduced, and due to the fact that the bolt abuts against the top face of the sliding rod from top to bottom, the torsional force is reduced. Most of the vibration force transmitted to the bolt is the vibration force on the horizontal plane, so that the bolt is not easy to disturb and is not easy to loosen.

This application belongs to the field of additive manufacturing, and particularly relates to an upright photopolymerization 3D printing device, which includes a projector, a feeding assembly, a build assembly, a scraper assembly, a power assembly, and a platform. The feeding assembly and the build assembly are mounted on the platform. Driven by the power assembly, the scraper assembly scrapes the raw material from the feeding assembly to the build assembly station. The raw material is then irradiated and shaped by the projector. The feeding and building processes are repeated to obtain a complete workpiece. This application has the effect of completing feeding, leveling, and compaction in the same step.

The utility model can eliminate the ball gap, improve the pendulum ball compactness and standardization, guarantee the fairness and ornamental of competition, improve the pendulum ball efficiency and precision.

The invention provides a method for increasing deep inert organic carbon in soil based on deep-dwelling earthworms, which comprises the following steps: carrying out ground weeding and land leveling treatment on a land parcel to obtain a pretreated land parcel; and performing field irrigation on the pretreated land parcel to obtain an irrigated land parcel. Deep-dwelling earthworms are put on the soil surface of the irrigated land parcel, and the total organic carbon content and the inert organic carbon content of the soil are increased through the deep-dwelling earthworms. Soil carbon sequestration result analysis shows that the soil organic carbon reserve is increased by 21.0% and the soil inert organic carbon reserve is increased by 29.3% when the deep-dwelling earthworms are independently used for improving the plot soil. The core of carbon sequestration is to increase the content of inert organic carbon in the soil of 40-80cm underground soil layer, and compared with active organic carbon, the inert organic carbon has longer solid storage time in the soil. In addition, the deep soil is not easy to disturb, and the preservation time of the organic carbon in the soil is further prolonged. The method also has remarkable environmental friendliness, and effective utilization of wastes can be realized.

The invention relates to a preparation method and application of quartz sand, in particular to a preparation method and application of titanium-doped quartz sand. The preparation method comprises the following steps: uniformly mixing silica sol and titanium sol with different particle sizes according to a certain proportion to obtain compound titanium-doped silica sol, enabling the compound titanium-doped silica sol to form homogeneous gel, drying to obtain silicon dioxide titanium-doped powder, and sintering the titanium-doped quartz sand. When the titanium-doped quartz sand is synthesized, raw materials are controllable, titanium doping is uniform, the titanium doping proportion is flexibly controlled, meanwhile, low-expansion quartz glass of different sizes can be melted through the gas melting process, the utilization rate of the raw materials is increased, and manufacturing of the bubble-free high-purity low-expansion quartz glass ingot is achieved.

This invention discloses a seawater treatment system for aquatic organism seedling and larval cultivation based on a natural ecological cycle. The system includes a natural sedimentation tank, a secondary sedimentation algae cultivation tank, a multi-stage dark sedimentation tank, a primary sand filter, a secondary sand filter, and a water storage tank connected to the end of the secondary sand filter. A pump is installed to connect to a water storage tower. A seawater concentration device and an ultrafiltration device are also included between the water storage tower and the aquatic organism seedling tank. The secondary sedimentation algae cultivation tank can be directly connected to a juvenile shellfish rearing tank for direct use in juvenile shellfish cultivation. The sand filter also features a backwashing design for easy recycling. The seawater processed through the primary and secondary sand filters, concentration device, and ultrafiltration device can be used for larval cultivation of aquatic organisms. This water treatment system, through its multi-stage structural design and combined with natural environmental control of light and shading, avoids the drawbacks of chemical and biological purification and the shortcomings of simple physical sand filtration in a natural and ecological way. This ensures a large-scale supply of water for aquatic organism seedling and shellfish cultivation, meeting the diverse needs of large industrial areas.

The present invention provides a bolt hole plugging device and a plugging method for a cast-in-place integrated thermal insulation board, the plugging device comprising: a retractable end plugging piece, the end plugging piece passes through the bolt hole when retracted, and the end plugging piece blocks one end of the bolt hole when expanded, and a first clamping structure is formed on one side of the end plugging piece; a grouting pipe, the end of the grouting pipe is provided with a second clamping structure, and the second clamping structure and the first clamping structure are mutually engaged. The present invention can plug the bolt holes on the inner side of the wall during the main structure construction stage to prevent the bolt holes from being left for too long and causing rainwater to penetrate, thereby affecting the thermal insulation effect, while avoiding the defects of high risk, low efficiency and high cost caused by high-altitude plugging on the outer side of the wall.
