The utility model discloses a circulating type seed kernel cleaning machine, which relates to the technical field of pumpkin seed cleaning machines, and adopts the technical scheme that the circulating type seed kernel cleaning machine comprises a base, a backflow water pool fixedly arranged at the top of the base, a plurality of fixing columns fixedly arranged at the top of the base, a spraying cleaning pool fixedly arranged at the tops of the fixing columns, and a concave drainage groove formed in the bottom of the spraying cleaning pool, the circulating type seed kernel cleaning machine has the advantages that the vibrator body drives the metal filter plate to vibrate at high frequency, pumpkin seed kernels move on the inclined filter plate in a jumping mode, preliminary screening (fine impurity separation) is achieved, the seed kernels can fully roll over, it is guaranteed that a spraying water curtain is covered without dead corners, and the cleaning efficiency is improved. The circulating water curtain assembly forms crossed water flow through a plurality of groups of spray headers, and is matched with low-pressure injection design (preventing seed kernels from being scattered), so that surface dirt, residual pulp and light and small impurities are effectively stripped, and the cleaning cleanliness is high.

The application relates to a preparation method of a three-layer integrated brake disc. The setting of the annular spacer can effectively avoid mutual invasion of the disc body friction material and the disc cap structure material in the powder filling process; the pre-pressing punch is used to press a surface which is basically the same as the inner surface before mold closing and pressing, so that the problem that the upper mold pressing surface is in contact with the uneven powder surface and is easy to cause the powder to be scattered can be effectively avoided; the above steps are coordinated, the disc body friction material and the disc cap structure material are in their respective positions, the interface consistency of the three-layer integrated brake disc can be effectively ensured, so that the performance of the disc body and the disc cap is ensured, and the batch stability is ensured.

This invention relates to the field of thickener technology, specifically disclosing a high-efficiency, uniformly distributed stabilizing tank for thickeners. The tank includes a stabilizing tank body, with a feed pipe installed on the top side wall of the body. One end of the feed pipe near the stabilizing tank body is connected to the interior of the body. Multiple openings are evenly distributed through the bottom of the inner wall of the stabilizing tank body. A fixing plate is movably installed inside the stabilizing tank body, and a first auxiliary mechanism is provided on the fixing plate. By incorporating openings, connecting rods, a fixing plate, and a rotating plate, this invention allows impurities such as ore fragments and mud lumps that affect the flocculation effect of the slurry to be blocked when the slurry is discharged from the openings to the bottom of the stabilizing tank body. The filtered slurry is then discharged downwards through the openings, free from the influence of ore fragments and mud lumps. Therefore, the flocculation effect of the slurry flocs is more stable, increasing the thickener's processing efficiency.

This invention discloses a land maintenance method and apparatus suitable for the cultivation of Suaeda salsa in wetland areas, relating to the field of ecological restoration and land improvement technology. Ecological restoration is achieved through an ecological restoration fertilizer comprising: 30-60 parts Suaeda salsa powder, 30-60 parts segmented Suaeda salsa grass, and 1-5 parts fermentation agent. The preparation method of the ecological restoration fertilizer includes the following steps: harvesting Suaeda salsa mother grass on land; dividing the obtained Suaeda salsa mother grass into two parts; pulverizing the first part and passing it through an 80-100 mesh sieve to obtain Suaeda salsa powder. This invention uses harvested Suaeda salsa mother grass as raw material to prepare an ecological restoration fertilizer. The resulting fertilizer has sufficient nutrients and a high microbial content, making it suitable for soil improvement in coastal tidal flats. It can enhance soil fertility, improve soil permeability, prevent soil compaction, and promote strong root development when planting Suaeda salsa.

The utility model relates to a kind of filling crystal structure for improving filling crystal bad, including filling crystal component and the liquid crystal box matched with filling crystal component;Filling crystal component includes filling crystal strip, first fiber layer, sponge strip, second fiber layer;Liquid crystal box includes substrate, glue frame set on substrate, glue frame surrounds a filling crystal area, glue frame side symmetry is provided with two flow guide walls, two flow guide walls between constitute filling crystal mouth, filling crystal area is close to the position of filling crystal mouth and is provided with shunt piece.The utility model is provided with first fiber layer and second fiber layer in the both sides of sponge strip, can filter small particle dirt impurities in liquid crystal, improve the quality of liquid crystal injected into box, avoid the problem caused by dirt, improve yield, reduce the cleaning and replacement frequency of sponge strip, improve filling crystal operation efficiency.Meanwhile, the flow guide wall of liquid crystal box can reduce the flow rate of liquid crystal under the cooperation of shunt piece, avoid liquid crystal directly impacting filling crystal area inside, further ensure the yield of product.

This utility model relates to the field of collagen peptide extraction technology, specifically an extraction device for fish collagen peptides. It includes a frame assembly, an extraction assembly, a feeding assembly, and a stirring assembly. The frame assembly includes a mounting frame; the extraction assembly includes an extraction cylinder; the feeding assembly includes a feeding cylinder; and the stirring assembly includes a motor and a filter box. The inner wall of the extraction cylinder is fully welded with a heat-conducting plate, forming a sealed heating layer between the extraction cylinder and the heat-conducting plate. A steam pipe is spirally wound inside the heating layer. Stirring blades are welded to the outer wall of the stirring shaft. The stirring blades exert shear force on the material, disrupting the raw material's structure, making it easier for collagen to be released from the fibers and dissolve in the aqueous phase. Simultaneously, it prevents fish skin residue or colloids from accumulating at the bottom of the extraction cylinder and prevents material near the heat-conducting plate from carbonizing due to localized overheating. During drainage, the stirring blades can push the material towards the conveying pipe, reducing residue.

This invention discloses an anti-clogging road drainage filtration structure in the field of road drainage filtration technology. It includes a road surface, a drainage channel, a movable fence, a reset component for resetting the movable fence, and a collection component for collecting leaves. A rotating groove is connected to the right end of a limiting groove, the diameter of which is equal to the diagonal length of the limiting block. The collection component includes a collection groove, a mounting frame, a lower support plate, and a rotating component for rotating the lower support plate. A collection groove is provided on the right end face of the drainage channel. The mounting frame is fixedly installed on the upper end face of the drainage channel, and the lower support plate is rotatably installed within the mounting frame. Water-permeable grooves are provided on both the front and rear ends of the fixed frame. This device can clear accumulated materials such as leaves when the movable fence is blocked, preventing large amounts of water accumulation on the road surface and ensuring normal pedestrian passage. Furthermore, all the cleared accumulated materials, such as leaves, are collected in the collection groove for convenient subsequent centralized processing by sanitation workers.
