The invention relates to an internal combustion engine which is provided with at least one cylinder (1) and a device used for recycling the exhaust gas. The cylinder is provided with an working chamber (2) which is limited by a reciprocating piston (3) and is loaded by the scavenging gas comprising compressed gas and fuel. The working chamber is provided with at least one scavenging gas inlet (6), at least one fuel inlet and at least one exhaust gas outlet (5). An exhaust duct (9) is connected with the exhaust gas outlet. A pressure impact (19) is generated in the exhaust duct (9) through theexhaust flowed out from the opened exhaust outlet (5). Through a device used for exhaust recirculation, one part of the exhaust can be used as the recirculation gas for being directly or indirectly guiding into the working chamber (2). Thus the dilution of the recirculation gas by the scavenging gas is prevented and a simple structure is realized. A recirculation gas outlet (21) is leaded out from the exhaust duct (9) connected with the exhaust outlet (5). The recirculation gas outlet can be closed through an attaching valve (22). The valve opens the attaching recirculation gas outlet (21) inan area between increasing and reducing the pressure impact (19) generated in the exhaust duct (9).

The invention discloses a disposable water cup storing and taking box capable of achieving non-contact taking. The disposable water cup storing and taking box capable of achieving non-contact taking comprises an outer frame, an inner frame, dialing-up gears, an orienting dialing piece, a feeding dialing piece, a button, a synchronous shaft, a synchronous pull rod, a spring and a cover; an elasticdialing piece on the orienting dialing piece can be made of a plastic elastic material, when the dialing-up gears are rotated in the set direction, the elastic dialing piece is compressed, the dialing-up gears can normally rotate, when the dialing-up gears have the tendency of reverse motion, an inner engaging gear of the dialing-up material is ejected by the elastic gear of the orientating dialing piece, and the direction rotation of the dialing-up gears can be limited; the tooth distance distribution of outer engaging gears of the dialing-up gears can meet the angle obtained through rotatingby one tooth distance each time, the distance obtained through rotating of two teeth is equal to the distance when two water cups are stacked together, the dialing-up gears distributed on two sides of the inner frame can be matched, the water cups can be clamped between narrow openings formed through the dialing-up gears on the two sides, and the function that each time, only water disposable water cup can be taken out, and in the taking process, the user does not need to make contact with the water cups is achieved.

The invention discloses a spring-shaped environment-friendly coating silver brazing material ring, which consists of at least two rings of spring-shaped silver brazing material cores with a median diameter of 2.0 mm to 56.0 mm wound by filaments or thin narrow strips of silver brazing material It is composed of silver brazing flux coating coated on the outside of the spring-shaped silver solder core. The silver brazing flux includes at least one of inorganic fluoride, potassium fluoroborate, boric anhydride, borate, and elemental boron. The silver brazing flux , polyvinyl alcohol, methyl cellulose and water according to a certain ratio to prepare flux solution, directly coated on the outer surface of the spring-shaped silver solder core, after drying, you can get a spring-shaped environment-friendly coating silver solder Finished material ring. The spring-shaped environment-friendly coating silver solder ring of the present invention, because it does not contain organic binders, complies with ROHS standards, greatly reduces environmental pollution during brazing and combustion, thereby protecting the health of operators, and greatly reducing the risk of environmental pollution. Reduced the labor intensity of the brazing process.

The invention relates to a biomass burner, comprising a frame (1), a combustion chamber (2), a position air chamber (3) and a storage bin (4), the air chamber (3) and the combustion chamber (2) passing through the The air passage (31) is communicated, one end of the air induction passage (31) is provided with a fan (32), and the other end is passed into the combustion chamber (2); the biomass particles enter the combustion chamber (2) from the storage bin (4) For combustion, the combustion chamber (2) is also provided with a flaming port (21) and an ash outlet (22), and also includes a feeding module (5), which includes a feeding channel (51) and a screw shaft (53) ), the screw shaft (53) is provided with a helical gear (54); the helical gear (541) of the helical gear (54) and the wall (42) of the discharge port (41) form an oblique notch (43), The biomass particles need to enter the channel inlet (5a) through the oblique notches (43); the present invention solves the problem that the equipment cannot operate normally because the biomass particles easily block the discharge port, and realizes quantitative feeding and continuously adjustable firepower , Automatic control, good shearing effect, preventing material blocking and tempering.

The invention provides a powdery material supply device and belongs to the technical field of supply machines. The device comprises a first friction disk, a second friction disk, a positioning disk, a positioning rod, a round plate and a plunger, wherein a first supporting shaft and a second supporting shaft are coaxial; the first friction disk is arranged on one side of the first supporting shaft; the second friction disk is arranged on one side of the second supporting shaft; the first friction disk and the second friction disk are attached to each other; the round plate is coaxially fixed on the other side of the second supporting shaft and is rotationally arranged in a round plate support; a radial through hole is formed in the round plate, and opening diameters of the two ends of the through hole are smaller than that the opening diameter of the middle part of the through hole; the plunger is vertically glidingly arranged in the through hole; a material injection pipe is arranged above an inlet; the positioning disk is coaxially fixed on the second supporting shaft; the middle end of the positioning rod is hinged to a positioning supporting seat by the aid of a hinge pin; a positioning jaw is arranged at one end of the positioning rod; and the other end of the positioning rod is connected with an electromagnet. Quantitative supply of powdery materials is realized, and the device is reasonable in structure and good in stability.

The invention discloses a chain type spacer quantitative feeding and assembling robot, which comprises a material barrel, an L-shaped bracket, a servo motor, a fixing plate and a chain, wherein the material barrel is arranged on the bracket; the bracket is arranged on the fixing plate; the servo motor is arranged on the fixing plate; a driving chain wheel is connected with the output end of the servo motor; the fixing plate is connected with a first driven chain wheel; the chain is meshed with the driving chain wheel and the first driven chain wheel; the chain is provided with grabbing blocks;each grabbing block is internally provided with an electromagnet; each grabbing block is provided with a circular groove; the depth of the circular groove is equal to the thickness of the spacer, a partition block is also fixed on the chain, the partition block is positioned between the grabbing blocks, the material barrel is at a certain distance from the upper surface of the grabbing blocks orthe partition block, and the distance is smaller than the thickness of the spacer; according to the invention, the quantitative feeding and assembling of the spacer are combined together, the efficiency is higher, the abrasion caused by friction between the spacer and other objects is reduced, and the stability of the spacer is more durable.
