The invention relates to the technical field of agricultural fertilizers, in particular to an instant potassium sulfate fertilizer and a preparation method thereof based on crystallization regulation, and the instant potassium sulfate fertilizer comprises the following components in parts by mass: 100-200 parts of potassium sulfate, 5-10 parts of a cosolvent, 0.3-0.5 part of a water softener and 0.3-0.5 part of a dispersant. Wherein the cosolvent is hydroxypropyl-beta-cyclodextrin or ammonium chloride, the water softener is any one of disodium ethylene diamine tetraacetate and sodium tripolyphosphate, and the dispersing agent is any one of sodium hexametaphosphate and tetrasodium pyrophosphate. According to the invention, the cosolvent is added in potassium sulfate, and in the prior art, potassium sulfate is generally irrigated and fertilized in a water and fertilizer manner, and a small amount of solid fertilizer is used because the dissolving speed and the dissolving rate of solid potassium sulfate are low, so that the fertility of the solid fertilizer is difficult to absorb by a root system after the solid fertilizer is fertilized; and after the hydroxypropyl-beta-cyclodextrin or ammonium chloride is added, the dissolution rate of the solid in the soil is increased, and the application requirement of the instant potassium sulfate fertilizer can be met by using the instant potassium sulfate fertilizer disclosed by the invention.

This utility model discloses a scale inhibition mechanism and a water outlet device with the scale inhibition mechanism. The scale inhibition mechanism includes: a support; a slow-release cylinder for storing scale inhibitor, the slow-release cylinder having several slow-release holes, and the slow-release cylinder being connected to the support; a movable member having a cavity, one end of which is open as a first port, the slow-release cylinder extending into the cavity through the first port, the movable member being movable relative to the support between a first position and a second position; an elastic member applying an elastic force to the movable member to move it to the second position; the movable member and the support are used to control whether the slow-release cylinder releases the slow-release liquid. Since the scale inhibition mechanism only releases the scale inhibitor when the water flow in the water outlet device is still, it slows down the flow rate of water and scale inhibitor through the slow-release holes, reduces the dissolution rate of the scale inhibitor, and slows down the consumption of the scale inhibitor.

The traditional Chinese medicine composition adopts pure traditional Chinese medicine components, has no obvious side effect and has a remarkable curative effect on chronic gastritis.

The present invention discloses a microporous ceramic adsorption platform and a method for preparing a non-marking product based on the microporous ceramic adsorption platform. The microporous ceramic adsorption platform does not contain a traditional groove design, thereby solving the problem of ultra-thin glass imprints and replacing the traditional groove vacuum adsorption platform. When preparing a non-marking product based on the adsorption platform, pattern photolithography, black glue film coating, soft baking, exposure and curing are sequentially performed to obtain a non-marking product. The manufacturing process is simple and easy to operate. The equipment matching, weight, flatness, adsorption effect, vacuum breaking effect, and particle adhesion of the manufactured microporous ceramic adsorption platform are verified; by comparing the traditional groove adsorption platform and the microporous ceramic adsorption platform under dark field strong light after photolithography under the same process conditions, it is confirmed that the product made using the microporous ceramic adsorption platform has the abnormal disappearance of the adsorption mark.

The application discloses a wastewater treatment device and a working method thereof. The device comprises a water storage pool, a movable base movably connected to the water storage pool, a moving unit and a particle throwing unit arranged on the movable base, a solution throwing unit arranged on the particle throwing unit, and a measuring unit connected to the solution throwing unit. The device can avoid the concentration of a certain area being too high to reduce the dissolution speed of the medicament, and the blades on the crushing rollers of the collecting assembly can also have a mixing effect, thereby accelerating the dissolution speed of the medicament.

A slow-release cleaning device for toilet tanks includes a bottle, a first buoyancy plug, and a second buoyancy plug. The bottle contains a cavity for holding cleaning agents, and the side wall of the cavity has a guide hole and an air pressure hole for connecting to the outside. The first buoyancy plug is movably installed at the guide hole and can open or close the guide hole as the water level in the tank rises. The second buoyancy plug is movably installed at the air pressure hole and can open or close the air pressure hole as the water level in the tank rises. A water cut-off level and a water flow range are formed between the guide hole and the air pressure hole from top to bottom, and the water cut-off level is not lower than the air pressure hole. When the water level in the tank is in the water flow range, water enters the cavity from the guide hole. When the water level rises to the water cut-off level, the cavity is filled with water, the first buoyancy plug floats up to close the guide hole, and the second buoyancy plug floats up to close the air pressure hole. This solution can perfectly control the release timing of the cleaning agent, further avoiding excessive dissolution and release of the cleaning agent, thus enhancing the slow-release effect.

Relating to the technical field of building materials, the invention provides a delayed coagulation type geopolymer concrete material, which comprises, by weight, 90-110 parts of recycled aggregate, 20-40 parts of a delayed coagulation type geopolymer, and 8-16 parts of water. Wherein the delayed coagulation type geopolymer comprises the following components in parts by weight: 50-70 parts of mineral powder, 30-50 parts of fly ash, 1-3 parts of a retarder and 10-20 parts of an alkali activator capsule; the invention also provides a preparation method of the delayed coagulation type geopolymer concrete material, which comprises the following steps: S1, recycling waste concrete, and crushing to obtain recycled aggregate; s2, filling sodium silicate powder into capsules to obtain alkali activator capsules; s3, mixing mineral powder, fly ash, a retarder and the alkali activator capsule prepared in S2 in proportion to obtain a delayed coagulation type geopolymer; and S4, stirring the recycled aggregate prepared in the S1, the delayed coagulation type geopolymer prepared in the S3 and water according to a ratio, and condensing to obtain the delayed coagulation type geopolymer concrete material.

The invention provides a slow-sinking fish feed and a preparation method thereof, wherein the slow-sinking fish feed comprises the following raw materials in parts by weight: 30-40 parts of fish meal, 20-30 parts of soybean meal, 10-20 parts of corn flour, 4-6 parts of vegetable oil, 2-4 parts of biofilm composite agent, 1-3 parts of starch nanocrystal, 0.5-1.5 parts of antibacterial agent, 0.6-1.2 parts of premix, wherein the biofilm composite agent is composed of sunflower wax, lignin, and sodium alginate in a mass ratio of (1.0-2.0): (1.0-1.5): (0.8-1.6). The crystalline structure and nanometer size of starch nanocrystal enable it to penetrate into the internal structure of the feed and be closely combined with other components in the feed. This combination increases the structural stability and hardness of the feed, allowing it to maintain integrity in water without being easily broken, thereby extending the suspension time of the feed in water. The biofilm complex forms a three-dimensional network structure in the feed, forming a stable protective layer, so that the slow-sinking fish feed produced has excellent performance in terms of sedimentation rate, water solubility index, hardness and sinking rate.
