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
The present invention relates to be used for the device that resin quantitative adds in a kind of Foundry Production, belong to the resin quantitative adding apparatus technical field in the foundry machinery.
Background technology
For the preparation of resin sand, reinforced puddle mixer effect is much better than adopting disc type once to adopt the stirring-cage type flow mixer in the Foundry Production, and the one, energy consumption reduces half, and the 2nd, the feature of environmental protection is good, and the 3rd, trash discharge few (it is few to clear up residual sand amount).The adding of stirring-cage type flow mixer resin at present mainly adopts various pumps directly to pump in the puddle mixer, the problem that this mode exists is: because resin viscosity under different temperatures is different, can be in the course of work because of the variation that causes the resin flow that enters of the variation of environment temperature and impurity, can't guarantee the stable of resin additional proportion in the continuous mulling process, and the cleaning of pump is in time necessary when running into stopping production, otherwise, time one length will cause scrapping, scale removal process is very inconvenient, causes the stirring-cage type flow mixer to be difficult to apply.
Chinese patent literature CN101347818 discloses a kind of " continuous automatic pug mixer ", wherein mention a kind of closed resin quantitative device, comprise tank body, end socket, capsule and pressure regulator valve, capsule is installed in the tank body, and its two ends are fitted in the two ends up and down of tank body, and the end socket of upper end is provided with the charge pipe that is communicated with capsule, valve is installed on the charge pipe, the end socket of lower end is provided with the carrier pipe that is communicated with capsule, and tracheae is installed on the tank body, and pressure regulator valve is installed on the tracheae.Above-mentioned closed resin quantitative device is an anti-oxidation system with air insulated, can guarantee the viscosity stabilization of resin effectively, and pressure line is unobstructed, makes flow and pressure proportional stable.But this device does not still solve resin because of variation of ambient temperature causes the problem of the variation of flow, still is difficult to guarantee effectively the stable of resin addition.
Summary of the invention
At in the existing Foundry Production because of variation of ambient temperature causes resin addition problem of unstable, the invention provides stable, the not influenced by ambient temperature resin quantitative replacement device of a kind of resin addition.
Resin quantitative replacement device of the present invention adopts following technical solution:
This resin quantitative replacement device comprises buncher, plunger displacement pump and displacement tank, capsule is installed in the displacement tank, the upper end of displacement tank is provided with the feed pipe that stretches in the capsule, feed pipe is provided with valve, the displacement tank upper portion side wall is provided with pouring orifice, the sidewall of displacement tank is provided with two oil exit pipes up and down, oil exit pipe is provided with valve, the bottom of capsule is provided with the resin delivery outlet, buncher is connected with plunger displacement pump by crank, the oil-in of plunger displacement pump is connected with hydraulic oil container, and the oil-out of plunger displacement pump is connected with pouring orifice on the displacement tank.
When frequency one timing of plunger displacement pump, the flow of the hydraulic oil that it pumps is constant, and after hydraulic oil entered displacement tank, the extruding capsule made the resin output in the capsule, and the resin of output is an equivalent with entering hydraulic oil.As long as the power of plunger displacement pump is abundant, when the viscosity of resin changes or pipeline when being obstructed, only can cause the fluctuation of output pressure, the fluctuation of flow can not appear, and this has just guaranteed the stable of resin output flow.Adjust the frequency of plunger displacement pump by the rotating speed of adjusting buncher, just can realize adjusting the flow of resin output.
The present invention makes resin output by the hydraulic oil fashion of extrusion, can realize the equivalent displacement of hydraulic oil to resin, resin does not directly contact with pump, fundamentally avoided the infringement of resin to pump, make the pump can steady operation and need not clear up maintenance, the resin output flow be not influenced by ambient temperature, has guaranteed the stable of resin output flow, adopt enclosed resin output simultaneously, prevent the resin oxidation.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Wherein: 1, buncher, 2, crank, 3, plunger displacement pump, 4, oil pipe, 5, feed pipe, 6, ball valve, 7, displacement tank, 8, pouring orifice, 9, capsule, 10, go up oil exit pipe, 11, ball valve, 12, oil exit pipe down, 13, ball valve, 14, the resin delivery outlet.
The specific embodiment
As shown in drawings, resin quantitative replacement device of the present invention comprises buncher 1, plunger displacement pump 3 and displacement tank 7.Capsule 9 is housed in the displacement tank 7, and the upper and lower port of capsule 9 all seals up.The upper end of displacement tank 7 is provided with the feed pipe 5 that stretches in the capsule 8, and feed pipe 5 is provided with ball valve 6.Feed pipe 5 is connected with the resinogen barrelling during use.The upper portion side wall of displacement tank 7 is provided with pouring orifice 8 and last oil exit pipe 10, and last oil exit pipe 10 is provided with ball valve 11.The lower sides of displacement tank 7 is provided with down oil exit pipe 12, and following oil exit pipe 12 is provided with ball valve 13.The bottom of capsule 9 is provided with resin delivery outlet 14.Buncher 1 is connected with plunger displacement pump 3 by crank 2, and the oil-in of plunger displacement pump 3 is connected with a hydraulic oil container, and the oil-out of plunger displacement pump 3 passes through oil pipe 4 and is connected with pouring orifice 8 on the displacement tank 7.
The course of work of the present invention is:
After the resin in the capsule 9 all is extruded, open ball valve 6, ball valve 11 and ball valve 13 once more, in capsule 9, charge into resin, enter next replacement process.
