Problems solved by technology
Due to the volatile nature of the modifier, the modifier gas in the modifier raw material tank is finally discharged from the vacuum pump, so this modifier weighing equipment has the following two technical problems: 1. Modifier The gas is corrosive, and after entering the vacuum pump, it will cause the aging of the vacuum pump gasket and affect the service life of the vacuum pump; 2. The modifier gas is finally discharged from the vacuum pump, which is easy to pollute the environment

The invention discloses a polyamide-6 granula modifying agent weighing system which comprises a modifying agent tank, a weighing tank, an electronic scale and a vacuumizing device. An air inlet is formed in the modifying agent tank. The vacuumizing device comprises a vacuum pump, an upper tank body and a water tank connected with the lower portion of the upper tank body. A spraying device is arranged at the upper portion in the upper tank body, a sponge block is arranged between the spraying device and a pumping out pipe, and the inlet position of the pumping out pipe is arranged above a horn-shaped hole. The invention further discloses a polyamide-6 granula modifying agent weighing method. The polyamide-6 granula modifying agent weighing system and weighing method have the advantages that when the vacuumizing device is in work, the weighing tank is pumped into negative pressure; when the vacuum pump in the vacuumizing device is in work, the upper tank body is pumped into negative pressure; modifying agent gas can be cleaned in the vacuumizing device; most modifying agents can be absorbed and dissolved in water. Thus, the effect on the vacuum pump is effectively reduced, and the service life of the vacuum pump is guaranteed. In addition, the discharge amount of the modifying agents is reduced, the environmental friendliness is achieved, and the pollution is avoided.
Description
technical field [0001] The invention relates to equipment and production steps for nylon 6 slices, in particular to a weighing system and a weighing method for nylon 6 slice modifiers. Background technique [0002] Nylon 6 chips are the main raw material for the production of nylon 6 fibers. In the production process of nylon 6 chips, modifiers are used as modifiers, which requires weighing of the modifiers during the production process. The existing weighing equipment for modifiers used in the production of nylon 6 slices includes modifier raw material tanks, weighing tanks and vacuum pumps. The modifier raw material tanks are connected to the weighing tanks through pipelines, and the weighing tanks are connected to the vacuum pumps through pipelines. Connection, when weighing, the vacuum pump works to generate negative pressure in the weighing tank, so that the modifier in the modifier raw material tank is pumped into the weighing tank to achieve weighing. Due to the vola...
