The utility model discloses a thermal power plant boiler air and smoke system leakage inspection device, which comprises an inspection device and a boiler, a smoke pipe is arranged on one side of the boiler, the inspection device comprises an inspection part, the inspection part comprises an installation part with a hollow central position, and a connecting pipe is arranged in the installation part. Smoke suction pipes with one ends extending out of the inner wall of the mounting part are arranged on the inner side of the connecting pipe at intervals, smoke sensors are arranged in the smoke suction pipes, air draft devices connected with the connecting pipe are arranged on the outer wall of the mounting part at intervals, and indicator lamps in one-to-one correspondence with the smoke suction pipes are arranged on the end face of one side of the mounting part at intervals. According to the utility model, the smoke leakage condition of the smoke tube can be checked in a multidirectional and multi-angle manner, the specific smoke leakage position on the smoke tube can be quickly and accurately judged by utilizing the lighting indication of the indicating lamps at different positions, and the leakage checking effect of the device is improved.

The invention relates to the technical field of additive manufacturing machines, and discloses a building additive manufacturing machine which comprises a ground rail. The vibrating device is used for vibrating the concrete material; the discharging device is used for stacking concrete materials; the feeding device is used for adding an early setting agent; a door-shaped frame is connected to the ground rail in a sliding mode, a mounting base is connected to the door-shaped frame in a sliding mode, and a material box is arranged on the mounting base. Through the arrangement of the vibrating device, a plurality of vibrating rods can vibrate in the up-and-down reciprocating movement process, the plurality of vibrating rods can vibrate and compact the concrete material in the material box during vibration, and the compactness of the concrete material is improved; through cooperation of the reciprocating screw rod and the ball carriage, the two mounting arms can drive the multiple vibration rods to reciprocate up and down in the material box, the contact area between the multiple vibration rods and a concrete material is increased, and therefore concrete with different depths in the material box can be vibrated and compacted.

This invention provides a device and method for separating tobacco scraps and recovering tobacco shreds in the cigarette manufacturing process. The tobacco scraps are fed into a primary vibrating screen via an elevator. "Hard, piercing" scraps are captured by an orthogonal curved screen plate and cylindrical screening holes with alternating dot matrix, separating tobacco dust and scraps with a diameter less than d1. The remaining material is fed into a secondary vibrating screen, where curved guide strips, a size-controlled screen plate, screening holes, separation holes, and a separation surface control the separation of hard scraps with a length greater than d2 and poor plasticity. Flexible tobacco shreds pass sequentially through the screening holes, separation holes, and separation surface, and are finally fed into a tobacco collection box. This invention provides high loosening force, screening efficiency, and low breakage rate for tobacco scraps, and accurately separates scraps from tobacco scraps, improving the recovery rate and quality of tobacco shreds.

The utility model discloses a feed divider for the front end of green feed crushing equipment, which comprises a bracket, a feed containing bin body is arranged at the top of the bracket, and a movable cutter rotating shaft is arranged in an inner cavity of the feed containing bin body; a first guide plate and a second guide plate which incline towards the movable cutter rotating shaft are oppositely arranged in an inner cavity of the material containing bin body on the two sides of the movable cutter rotating shaft; the bottom end of the first guide plate faces the top of the movable cutter rotating shaft, the bottom end of the first guide plate is fixedly connected with one end of the first supporting plate, the other end of the first supporting plate is fixedly connected with the bottom of the containing bin body, and the bottom end of the second guide plate is connected with the fixed cutter block perpendicularly arranged at the bottom of the containing bin body; a material gathering and conveying opening is formed in the bottom of the material containing bin body under the movable cutter rotating shaft; an extension table is arranged on one side of the support on the same side with any bearing seat, a power motor is arranged at the top of the extension table, and the output end of the power motor is connected with one end of the movable cutter rotating shaft. The top of the material containing bin body is not shielded, an opening is large, clamping and feeding are convenient, green feed feeding is convenient, and the automation degree of the whole smashing device is high.

The present application relates to the technical field of waterborne polyurethane materials, and particularly relates to a low VOC waterborne PU foam pad and a preparation method thereof. The foam pad is formed by foaming and curing of a waterborne polyurethane dispersion, and two types of aldehyde-trapping sites are simultaneously introduced into the same porous framework, i.e. an amidoxime group formed by post-conversion of a nitrile group precursor by hydroxylamine, and an aminooxy group obtained by coupling and deprotection of T-BOC-aminooxy-diglycol-amino through a carboxyl anchoring site under an EDC and NHS activation system; and a water-dispersible blocked polyisocyanate crosslinking agent is used to form a crosslinking network by pyrolytic deblocking, so as to achieve rapid capture and durable retention of aldehydes such as formaldehyde and acetaldehyde under water washing and humid heat conditions, and simultaneously help to reduce VOC emission of the material.

Provided are a bispecific antibody combination and a use thereof. The bispecific antibody combination comprises a bispecific antibody I and a bispecific antibody II. The bispecific antibody I comprises a CD3-targeting domain and a tumor-associated antigen-targeting domain, and the bispecific antibody II comprises a 4-1BB-targeting domain and a tumor-associated antigen-targeting domain. Further provided are a pharmaceutical composition, a test kit, a kit of parts and an administration device containing the same, and a method of treating cancer by using the same. The concomitant use of the bispecific antibodies not only reduces the exhaustion of T cells, but also significantly facilitates tumor killing at a later stage. Moreover, the concomitant use of the bispecific antibodies, especially when targeting different epitopes of the same tumor-associated antigen or targeting different tumor-associated antigens, produces a strong synergistic killing effect. The use of the bispecific antibody combination and the pharmaceutical composition containing the same provides a potential clinical solution for effectively treating solid tumors.
