Embodiment Construction

[0011] As shown in the drawings, the quantitative resin replacement device of the present invention includes a speed-regulating motor 1 , a plunger pump 3 and a replacement tank 7 . Capsule 9 is housed in the replacement tank 7, and the upper and lower ports of the capsule 9 are all sealed. The upper end of the replacement tank 7 is provided with a feed pipe 5 extending into the capsule 8, and the feed pipe 5 is provided with a ball valve 6. Feed pipe 5 is connected with resin original barrel during use. An oil filling port 8 and an upper oil discharge pipe 10 are provided on the upper side wall of the displacement tank 7 , and a ball valve 11 is provided on the upper oil discharge pipe 10 . A lower oil discharge pipe 12 is provided on the lower side wall of the displacement tank 7, and a ball valve 13 is provided on the lower oil discharge pipe 12. The bottom of the capsule 9 is provided with a resin output port 14 . The speed regulating motor 1 is connected with the plung...

Abstract

The invention provides a resin quantitative replacement device which comprises a speed regulating motor, a plunger pump and a replacement tank, wherein a rubber bag is arranged in the replacement tank, the upper end of the replacement tank is provided with a feeding pipe which extends into the rubber bag, a valve is arranged on the feeding pipe, the upper side wall of the replacement tank is provided with an oil filling hole, the side wall of the replacement tank is provided with an upper oil drain pipe and a lower oil drain pipe, valves are arranged on the oil drain pipes, the bottom of the rubber bag is provided with a resin output hole, the speed regulating motor is connected with the plunger pump by a crank, an oil filling hole of the plunger pump is connected with a hydraulic oil tank, and an oil outlet of the plunger pump is connected with the oil filling hole of the replacement tank. The invention outputs the resin by a hydraulic oil extruding method and can realize the quantitative replacement of hydraulic oil with the resin, the resin does not in direct contact with the pump, which radically avoid the damage of the pump by the resin, the pump can stably operate and does not need to be cleaned and maintained, the resin output flow is not influenced by environmental temperature to ensure the stable resin output flow, and meanwhile, the seal type resin output is adopted to prevent resin oxygenation.

Description

technical field [0001] The invention relates to a device for quantitatively adding resin in casting production, and belongs to the technical field of resin quantitatively adding devices in foundry machinery. Background technique [0002] For the preparation of resin sand in foundry production, the effect of using a cage-type continuous sand mixer is much better than that of a disc-type one-time feeding sand mixer. First, energy consumption is reduced by half, second, environmental protection is good, and third, waste discharge is less. (cleaning less residual sand). At present, the addition of resin to the cage-type continuous sand mixer mainly uses various pumps to directly pump it into the sand mixer. The problem with this method is: because the viscosity of the resin is different at different temperatures, the working process will be affected by the ambient temperature. The change of resin flow rate due to the change of flow rate and the entry of impurities cannot guaran...
