The pressure sensor is arranged in the press cavity, the pressure reducing port connected with the press cavity is arranged on the lower press cage shell, and the hydraulic electromagnetic valve is arranged on the pressure reducing port, so that control over pressure in the press cavity is achieved, and the danger that the pressure in the press cavity is too high and accordingly explosions are generated is prevented.
Description
Technical field
The utility model relates to a kind of oil press, relates in particular to a kind of oil press of row pressure in time.
Background technology
Oil press just refers to the effect by means of mechanical external force, the machine that grease is squeezed out from oil plant.During oil press running, the oil plant of handling well enters squeezing thorax from feed arrangement.Under the screw thread rotation effect of pressing screw, charging aperture advances to cake output end direction gradually.Making to squeeze each section of volume in thorax dwindles gradually; Because pressing screw screw thread continuously pushes squeezing thorax by material embryo, front like this resistance pusher ground produces pressure again, and compression oil plant, squeezes out oil.But excessive when the pressure squeezing in thorax, even if be that oil press quits work at once, the pressure squeezing in thorax also likely can not get rapid release, the generation with regard to perils such as likely setting off an explosion like this.Therefore be necessary to design a kind of oil press that can alleviate at once squeezing breech pressure.
Utility model content
Utility model object: a kind of oil press that can discharge at once oil extruder breech pressure is provided.
Technical scheme: a kind of oil press of timely row pressure, described oil press comprises the feeder that squeezes thorax and oil plant is provided to squeezing thorax, described squeezing thorax is connected to form by the inwall of upper squeezing cage shell and the inwall of lower squeezing cage shell that squeeze cage, squeeze in thorax and be provided with spiral squeezing axis, spiral squeezing axis comprises mandrel and is assembled in the pressing screw and distance circle on mandrel, spiral squeezing axis is connected in transmission device near one end of feeder, the inwall of described upper squeezing cage shell is provided with pressure sensor in the position away from feeder, the position of described lower squeezing cage shell corresponding pressure sensor is provided with and the pressure-reduction outlet that squeezes thorax and be connected, described pressure-reduction outlet is connected with hydraulic buttery valve, described pressure sensor, hydraulic buttery valve and transmission device are connected to control module, described hydraulic buttery valve is normally off.
Operation principle: when the temperature in the squeezing thorax that pressure sensor measures surpasses the predetermined pressure of control module.Control module is controlled hydraulic buttery valve and is opened, and the part fluid now squeezing in thorax flows out from pressure-reduction outlet; When the pressure in the squeezing thorax that pressure sensor measures is got back to the setting pressure of control module, it is closed that control module is controlled hydraulic buttery valve.
Beneficial effect: the utility model arranges pressure sensor in squeezing thorax, at squeezing cage shell, the pressure-reduction outlet being connected with squeezing thorax is set, at pressure-reduction outlet, hydraulic buttery valve is set, realizes the control of squeezing breech pressure, prevent from producing because of the hypertonia in squeezing thorax the danger of blast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The specific embodiment
As shown in Figure 1, oil press comprises and squeezes thorax 1, gear-box portion and to squeezing the feeder 2 that oil plant is provided in thorax 1.Squeezing thorax 1 is connected to form by the inwall of upper squeezing cage shell and the inwall of lower squeezing cage shell that squeeze cage 3.Squeeze the squeezing cage shell of cage 3 and make with spheroidal graphite cast-iron, this squeezing cage shell comprises squeezing cage shell and lower squeezing cage shell, between upper squeezing cage shell and lower squeezing cage shell, is to be bolted shape all-in-one-piece.On
In squeezing thorax 1, be provided with spiral squeezing axis 4, spiral squeezing axis 4 is to be formed with distance circle by mandrel and the pressing screw being assembled on mandrel, and pressing screw and distance are enclosed and by flat key, be connected in lower squeezing cage shell respectively.Spiral squeezing axis 4 is connected in transmission device 5 near one end of feeder 2, and transmission device 5 is connected in control module.When oil press is worked, the oil plant in charging aperture enters squeezing thorax 1 is under the screw thread rotation effect of pressing screw, and charging aperture advances to cake output end direction gradually.The diameter of spiral squeezing axis 4 reduces to fuel-displaced portion gradually from feeder, and it is also diminishing therefore squeezing each section of volume in thorax 1.Because pressing screw screw thread continuously pushes squeezing thorax by material embryo, front like this resistance pusher ground produces pressure again, and compression oil plant, squeezes out oil.The inwall of upper squeezing cage shell is provided with pressure sensor 6 in the position away from feeder, the position of described lower squeezing cage shell corresponding pressure sensor 6 is provided with and the pressure-reduction outlet (not shown) that squeezes thorax and be connected, and upper squeezing cage shell is provided with an oil-in (not shown) in the position near feeder 2.Pressure-reduction outlet is connected with hydraulic buttery valve (not shown), and hydraulic buttery valve is that normally closed type is connected in control module, and pressure sensor 6 is connected to control module with hydraulic buttery valve.
Control module is provided with predetermined pressure, when the pressure in the squeezing thorax 1 that pressure sensor 5 detects surpasses the predetermined pressure of control module, control module is controlled hydraulic buttery valve and is opened, the fluid squeezing in thorax 1 outwards flows out from pressure-reduction outlet, the fluid outwards flowing out may contain a large amount of dregs of fat and need to squeeze, magnetite is poured the dregs of fat into squeezing thorax by oil-in and is carried out secondary oil expression, and does not need additionally this fluid to be processed.Because the diameter of spiral squeezing axis 4 reduces to fuel-displaced portion gradually from feeder 2, so it is also diminishing squeezing each section of volume in thorax 1, namely continuously material embryo to be pushed and squeeze the pressure that thorax 1 produces be also not wait to pressing screw screw thread, and squeeze the pressure of thorax 1 in the position away from feeder 2, be maximum, pressure-reduction outlet is arranged on to this and can the most directly reduces and squeeze the pressure that surpasses control module predetermined value in thorax, thereby can reduce dangerous generation.
