The application discloses a method for cracking tar into high value-added products, which adopts a route of separating light components by fractional distillation and then hydrogenating heavy components, so that the yield of target products can be affected by hydrogenation of naphthalene, methyl naphthalene and the like below 250 DEG C in the process of hydrocracking, and on the other hand, the components below 250 DEG C account for about 30% to 50%, so that the hydrogen consumption in the subsequent hydrocracking can be reduced by separating the components in advance. After the heavy fraction is subjected to hydrocracking, part of polycyclic aromatic hydrocarbons in the heavy fraction can be cracked into part of monocyclic aromatic hydrocarbons, which can be used for producing aromatic solvent oil, so that the light fraction in the hydrocracking product is separated and mixed into the light fraction generated by pre-fractionation, and the next step processing is carried out, so that the yield of high value-added products can be further improved.

The utility model discloses a crucible vibration platform which comprises a crucible body and a working table, a plurality of supporting legs are fixedly installed on the bottom wall of the working table, a bottom plate is fixedly installed at the end of each supporting leg, and connecting plates are fixedly installed on the upper end face of the working table through two supporting plates. Connecting rods are installed on the bottom walls of the two connecting plates in a sliding and penetrating mode, limiting plates are fixedly installed at the ends of the two connecting rods, the inner walls of the two limiting plates are connected with the bottom walls of the connecting plates on the same side through elastic mechanisms, and a vibrating plate is fixedly installed at the ends of the two connecting rods jointly; the crucible body is installed on the upper end face of the vibration plate in a sliding mode. Through the arrangement of the cam, the spring, the extrusion block and other components, when the cam continuously rotates and is in intermittent contact with the inner wall of the extrusion groove, the vibration plate can shake up and down in a reciprocating mode under the elastic action of the spring, and therefore the situation that raw materials are heated unevenly in the crucible body, and consequently the quality and the yield of products are affected can be avoided.

The utility model discloses a reciprocating type material screening machine for chemical production, including chemical material screening box, its top end is equipped with the feeding seat, and the feeding seat is used for the delivery of chemical raw material, still includes annular flow guide seat, the annular flow guide seat is the inside hollow structure, and the inside installation of chemical material screening box of annular flow guide seat just below has dispersion mechanism, the dispersion mechanism carries out the effect of dispersion and scattering of chemical raw material. The reciprocating type material screening machine for chemical production, the inside installation of chemical material screening box has trapezoidal flow guide seat. The reciprocating type material screening machine for chemical production is scattered to chemical raw material through dispersion mechanism, and convenient discharge can be carried out simultaneously, realizes the protection to the screen frame compared with traditional technology, avoids the situation that the raw material is too much and is inconvenient to screen, and through the connecting structure, realizes that the staff quickly connects the material box and changes, is favorable to improving the overall work progress.

The application discloses a lubricating oil production impurity filtering and separating device, which comprises a reaction furnace, an oxygen interface, a hydrogen sulfide interface and a sulfur dioxide outlet are arranged outside the reaction furnace, and a vibration groove accommodating a vibration mechanism is formed in the inside of the reaction furnace; a motor, a rotating shaft, a vibration groove gasket, a rack and a knocking mechanism are arranged in the vibration mechanism, the motor is fixedly connected with the reaction furnace, and the rotating shaft is fixedly connected with the knocking mechanism, and the application relates to the field of lubricating oil impurity separation. The rotating shaft is swung by driving the motor to reversely rotate, the knocking mechanism is swung by the rotating shaft, the knocking mechanism is provided with a knocking assembly, the sulfur and impurities on the bottom plate of the reaction furnace are knocked off by the knocking assembly during the swinging of the knocking mechanism, the sulfur and impurities on the bottom plate of the reaction furnace are separated from the reaction furnace, the heat conduction efficiency of the reaction furnace is avoided from being affected, the yield of sulfur dioxide is affected, and even the reaction furnace is exploded due to uneven heat conduction.
