The invention relates to the technical field of petroleum drilling and discloses a reservoir protection agent composition, a drilling fluid containing the reservoir protection agent composition and application thereof. The reservoir protection agent composition contains polymer elastic granules, and at least one of synthetic fibre and a film-forming agent. The polymer elastic granules contain specific contents of an intermediate product, alkali, salt and water. The intermediate product is prepared from raw materials including specific contents of acrylamide, a cationic monomer, a cross-linking agent, an initiator, a toughening material and water. The reservoir protection agent composition can help effectively prevent a drilling fluid from invading into a fractured reservoir and rapidly seal fractures in the fractured reservoir. The sealing rate is high, and sealing layer is easy to flow back. The reservoir protection agent composition is simple to use, and has good environmental protection performance and excellent reservoir protection performance.

The invention belongs to the field of biofuel manufacturing devices, and provides a special heating ring die system device for a biomass granulator to improve the production efficiency and increase the raw material adaptability of the biomass granulator. The system device sequentially includes a torus pressing flange, an upper heating element, a torus ring die, a lower heating element and a torusring die baseboard from top to bottom, the upper part of the ring die is provided with an upper groove for accommodating the upper heating element, the upper part of the ring die baseboard is providedwith a lower groove for accommodating the lower heating element, and the pressing flange, the upper heating element, the ring die, the lower heating element and the ring die baseboard are fixed by fastening bolts, through holes and fixing holes in order to make the upper heating element and the lower heating element respectively sealed in the upper groove and the lower groove and isolated from the outside. The upper heating element and the lower heating element adopt electric heating rods or PTC heating rods, and are closely attached to the pressing flange, the ring die and the ring mold baseboard to ensure good heat conduction. The granulator using the device does not need to be preheated for mixing, so the turn-on time is obviously saved.

The invention belongs to the technical field of lithium-ion battery production equipment, and in particular relates to a liquid injection device, which includes a liquid injection cup cavity, an upper fixing plate, a lower fixing plate, a liquid injection nozzle, a liquid injection port, a first blocking rod, a second blocking rod The rod, the first drive assembly and the second drive assembly, the upper end surface and the lower end surface of the liquid injection cup cavity are in close contact with the upper fixed plate and the lower fixed plate respectively, the liquid injection port is arranged on the upper fixed plate and the liquid injection port is connected with the injection port The cavity of the liquid cup is connected, the liquid injection nozzle is located under the lower fixing plate and the liquid injection nozzle is connected to the cavity of the liquid injection cup, the upper fixing plate is provided with a through hole communicating with the cavity of the liquid injection cup, and the end of the through hole is connected with a Gas nozzle. The present invention improves the existing liquid injection device of lithium-ion batteries from the principle of liquid injection, and changes the existing single liquid injection into reciprocating small-scale repeated liquid injection to remove residual air bubbles in dead corners inside the battery core, thereby greatly improving the performance of the battery. The qualification rate of the cell injection process improves the quality of the cells in the liquid injection process without affecting the overall production capacity.

The invention discloses a working table for display panel testing. The working table comprises an upper supporting block, a lower supporting block, a left supporting block and a right supporting blockwhich are used for fixing a display panel to be detected. The distance between the upper supporting block and the lower supporting block is adjustable. The distance between the left supporting blockand the right supporting block is adjustable. The upper supporting block, the lower supporting block, the left supporting block and the right supporting block define a light transmitting space. The upper supporting block, the lower supporting block, the left supporting block and the right supporting block are provided with fixing parts used for fixing a polarizing plate to the light transmitting space. The working table for display panel testing is adopted for both manual detection and automatic optical detection. Input of equipment is reduced, and the detection cost is lowered.

The invention relates to a process arrangement method for mixed jet cleaning. The method employs high-pressure mixed jet descaling units having a plurality of abrasive materials with different granularities. The high-pressure mixed jet descaling units are arranged along a tape transport direction of a metal plate. The high-pressure mixed jet with large granularity abrasive materials is arranged at an original inlet area of the metal plate, with the granularity of 20 meshes-60 meshes and inject pressure of 15 MPa-80 MPa; the high-pressure mixed jet with medium granularity abrasive materials is arranged at downstream of the high-pressure mixed jet descaling unit with the large granularity abrasive materials, with the granularity of 40 meshes-80 meshes and inject pressure of 10 MPa-60 MPa; the high-pressure mixed jet descaling unit with small granularity abrasive materials is arranged at downstream of the high-pressure mixed jet descaling unit with the medium granularity abrasive materials, with the granularity of 60 meshes-120 meshes and inject pressure of 10 MPa-50 MPa; the metal plate realizes the front and back descaling of the metal plate via the above jet descaling units; and the washing of the metal plate is finished by passing the descaled metal plate through a high-pressure pure water cleaning unit, a wiping unit and a compressed air blowing unit. The complete removing treatment of the scales on two sides of the coal metal plate is realized via a jet way.
