The invention discloses a suction unit used in surgery, which comprises a flow distribution tube, a smoke suction unit and a liquid suction unit. The flow distribution tube comprises a main tube, a first flow distribution branch and a second flow distribution branch, the smoke suction unit comprises a suction tube, the suction tube is communicated with the first flow distribution branch and connected with a skin protecting towel, the liquid suction unit comprises a tubular suction handle, the front end of the tubular suction unit handle is connected with a suction head, and the rear end of the tubular suction handle is communicated with the second flow distribution branch via a flow guiding tube I. The smoke suction unit is arranged at an opening of a surgical cavity, the suction range ofthe suction tube is large, smoke generated during electric scalpel surgery can be thoroughly sucked away, injury to medical staffs due to the smoke is avoided, the skin protecting towel encircles a surgical incision, and tissues of the incision can be prevented from being sucked away by the suction tube; the liquid suction unit can suck away blood, incision irrigation liquid, fester and the like which are generated during the surgery, and is convenient in operation; and the smoke suction unit is integrated with the liquid suction unit, the suction unit is simple in structure, and the quantityof suction equipment required in a surgery process is reduced.

The invention discloses a plastic injection mold, and relates to the technical field of injection molding. A rear formwork bottom plate is included. A rear formwork on the rear formwork bottom plate is detachably connected with a front formwork on a front formwork bottom plate. A cavity for mold injection molding is formed by a rear mold core formed by the upper portion of the rear formwork and afront mold core formed at the lower portion of the front formwork. Each exhaust assembly comprises a pipe cavity, wherein one end of the pipe cavity communicates with the cavity, the other end of thepipe cavity upwards extends out of the top face of the front formwork bottom plate, meanwhile, the pipe cavity is internally provided with a matched exhaust pipeline, and one end of the exhaust pipeline communicates with the cavity and is provided with a ventilation micro hole ring. According to the plastic injection mold, surplus air in the cavity is exhausted in time, accordingly, the phenomenonof air hole generation in the injection molding process is avoided, and the mold injection molding effect is improved; and an activated carbon adsorption plate can be utilized for adsorbing harmful molecules contained in hot melting plastic raw materials, and accordingly the body health of workers is facilitated while exhausting is guaranteed.

The invention relates to the technical field of coke oven flue gas treatment, in particular to a coke oven flue gas treatment system, comprising a coke oven main body, a dust collector is arranged on one side of the coke oven main body, and a coke oven main body and a dust collector are arranged between the coke oven main body and the dust collector. A connecting pipe is connected, a charging pipe is arranged on the surface of the main body of the coke oven, one end of the charging pipe is provided with an opening, and the inside of the charging pipe is movably connected with a charging smoke blocking device. The dust collector is provided with a filter screen, a heat sink, an auger, a motor and a fan, etc., so that the particulate matter in the flue gas can be separated and sent to the combustion furnace for combustion again, avoiding excessive waste of resources. The coke oven flue gas treatment system of the present invention can prevent flue gas from escaping from the furnace when adding fuel, can protect the environment, and can reduce the harm of flue gas to staff.

The invention discloses a neurology multifunctional automatic replenishment device. When in use, the medical staff can firstly operate the operation panel according to the eating time of the patient, set the corresponding starting time for the timer, and open the water tank through the timer to make the clear water Enter the mixing tank, and then turn on the first motor through the timer, so that the stirring rod can stir and break the food, and filter the food under the double function of the filter screen and the filter box. At the same time, the medical staff can also use the temperature controller to The heating tube is heated, and the temperature is evenly transmitted to the food in the storage tank to realize the heating treatment of the food. Finally, under the action of the extrusion force of the electric push rod, the food in the storage tank is sent to the patient's stomach. The multi-functional automatic feeding device, on the basis of stirring and crushing food, also adds functions such as stirring and filtering, food heating, etc., which can not only automatically send liquid food into the patient's stomach, but also increase the comfort of the patient during eating.

The invention relates to a sand box overturn cleaning device for an iron mold casting production line. The device comprises a sand box feeding mechanism, a sand box overturn mechanism, a sand box delivery mechanism and a sand box cleaning mechanism; according to the travelling direction of a sand box, the sand box feeding mechanism is arranged in front of the sand box overturn mechanism, the sand box delivery mechanism is arranged behind the sand box overturn mechanism, and the sand box cleaning mechanism is arranged behind the sand box delivery mechanism. Lifting equipment does not need to be used for lifting when the sand box is overturned, the operation step is greatly simplified, the safety loophole is eliminated, the sand box overturn efficiency is improved, and the sand box is cleaned at the same time; the residual sand can be removed, so that the sand box can be directly used.
