The invention relates to 3D printing equipment with a precise leveling function. The 3D printing equipment comprises a sliding seat, a detection part, horizontal parts, a supporting frame arranged on the side wall of the sliding seat, and an adjusting part suitable for sliding on the outer wall of the supporting frame, wherein the detection part and the horizontal parts are suitable for sliding on the top of the sliding seat; after the adjusting part is rotated, the adjusting part can extrude or loosen raw materials, so that the adjusting part can adjust the tightness of the raw materials; and the horizontal parts are adjusted, wherein the horizontal parts enable the detection part to be horizontal. In the using process of the 3D printing equipment, the transverse length of an adjusting rod in the adjusting part is controlled by rotating the adjusting part, and then the attaching degree of the adjusting part and the raw materials is adjusted, so that the feeding speed of the raw materials is adjusted; and if the phenomenon that a base of the 3D printing equipment is not flat occurs, in order to guarantee the product printing quality, four horizontal parts above the sliding seat need to be rotatably adjusted so as to keep a printing plate in a horizontal state.

The invention discloses a method for treating organic silicon slag by the aid of chlorination processes. The method includes steps of 1, adding reducing agents into the organic silicon slag to obtainmixtures after aging treatment is carried out on the organic silicon slag, continuously adding the mixtures into a boiling chlorination furnace, carrying out chlorination roasting and selectively chlorinating copper and iron in the organic silicon slag; 2, adding slag chlorinated at the step 1 into water, and washing and dissolving copper chloride and iron chloride in the slag to obtain chloride mixed solution; 3, adding iron powder into the chloride mixed solution, replacing copper in the chloride mixed solution and carrying out filtering to obtain copper powder and iron-containing solution;4, adding quicklime into the iron-containing solution, regulating the pH (potential of hydrogen) value of solution, filling the solution with air, oxidizing the solution, and carrying out filter separation to obtain iron hydroxide precipitates and iron-precipitated solution; 5, drying the iron hydroxide precipitates to obtain finished products. The method has the advantages that environmental protection problems due to waste organic silicon slag can be solved by the aid of the method, valuable metal copper, iron, silicon and the like in the organic silicon slag can be recycled by the aid of the method, and accordingly the method is economical and environmentally friendly.

The invention discloses an efficient continuous vacuum microwave drying machine and belongs to the field of drying processing machines which can keep the vacuum degree under the condition of continuous feeding and discharging of materials in a solid state or a semi-liquid state or other states of food products, Chinese herbal machine products, chemical products and agricultural and sideline products. The efficient continuous vacuum microwave drying machine is mainly provided with a feeding conveying belt, a rotary drum type feeding / discharging sealing device, a vacuum chamber, a heating device, a microwave magnetic-control device, a material conveying belt, a material turning device, a vacuum recovering system and a cleaning device. According to the drying machine, by the adoption of a steam and microwave combined heating drying way, energy and time can be saved by over 20%-30% compared with a single microwave heating drying way or a single steam heating drying way; the material turning device and the cleaning device for processing solid materials and semi-liquid materials are arranged, a condensation recovering device is added into the vacuum system, in this way, fragrant gas can be collected and converted into liquid, beneficial gas, poisonous and harmful gas, inert gas, gas prone to oxidation, combustible and explosive gas and the like can be recycled, high quality and high benefits of processed products can be achieved, environment protection is facilitated, and social comprehensive benefits are also facilitated.

The invention discloses a mixer capable of eliminating bubbles, and relates to the technical field of mixers, in particular to a supporting frame and a positioning clamping column, a positioning groove is fixedly formed in the right end of the supporting frame, a connecting disc is arranged on the inner surface of the supporting frame, a sliding way is arranged in the connecting disc, a built-in pipe is arranged in the sliding way in a sliding mode, and the built-in pipe is connected with the positioning clamping column. An auxiliary pipe is installed at the top end of the built-in pipe in a threaded mode. According to the mixer capable of eliminating the bubbles, the identification outer disc is provided with character identifications with different colors, so that the identification outer disc can be rotated along the outside of the bottom pipe when articles in the pipe body are discharged, and the identification outer disc is rotated to a color identification area at a proper position according to the discharging times; and meanwhile, the color identification area of the identification outer disc is aligned with the triangular identification outside the bottom pipe, so that a user can intuitively judge the number of times of discharging in each discharging pipe according to the material mixing requirement of the articles, the problem of excessive discharging or insufficient discharging is avoided, the structure is simple, and the user can conveniently use the device.
