Abstract
The utility model discloses an air pulp sealing device for batch mixer discharging gate. An air-pressure pump is connected with an air pulp sealing element through an air inlet pipe and an air inlet interface, the air pulp sealing element is tightly stuck on the environment of the discharging gate and is fixed on a machine slot by a fixing seat, and a vacuum pump is connected with the air pulp sealing element through an air outlet pipe and an air outlet interface. After the discharging gate is closed, compressed air generated by the air-pressure pump is filled in the air pulp sealing element through the air inlet pipe and the air inlet interface, a pressure is simultaneously transferred to the air pulp sealing element, and the air pulp sealing element generates the elastic deformation under the combined action of the compressed air and the fixing seat, is tightly stuck on the environment of the discharging gate and is filled in each corner between the environment of the discharging gate and the machine slot so as to prevent materials inside the machine slot of the batch mixer being extruded; before the discharging gate is opened, the vacuum pump extracts the air inside the air pulp sealing element through the air outlet pipe and the air outlet interface, and the air pulp sealing element is tightly stuck on the fixing seat.
Description
Affiliated technical field
The utility model relates to a kind of mixer of feed processing industry, particularly relates to the discharge door gas flesh sealing mechanism of mixer, belongs to the feed manufacturing machine field.
Background technology
At present, the employed discharge door sealing mechanism of feed processing industry mixer all is a pressing plate fit sealing bar formula, the fixing relatively difficulty of the sealing strip of this seal form, if sealing strip is too near from discharge door, will aggravate the wearing and tearing of sealing strip during the switch discharge door, even cause sealing strip to be scratched by discharge door, if sealing strip is too far away from discharge door, then sealing strip does not have sealing effectiveness.
Summary of the invention
The purpose of this utility model is at above problem, and a kind of novel mixer discharge door gas flesh sealing mechanism is provided, and it can eliminate the problem that the discharge door that causes because of the making error leaks material, sealing difference.
The purpose of this utility model is realized by the following technical programs: this mechanism mainly is made up of pneumatics pump, air inlet pipe, intake interface, holder, gas flesh seal, discharge door, trough, the interface of giving vent to anger, escape pipe, vavuum pump.The pneumatics pump links by air inlet pipe and intake interface and gas flesh seal, and gas flesh seal is fixed on the trough near around the discharge door by holder, and vavuum pump links by escape pipe and give vent to anger interface and gas flesh seal.After discharge door is closed, the Compressed Gas that the pneumatics pump produces is full of in the gas flesh seal by air inlet pipe and intake interface, simultaneously pressure is delivered on the gas flesh seal, make gas flesh seal under the acting in conjunction of compressed air and holder, produce strain, be close to discharge door around, and be full of around the discharge door and each corner between the trough, prevent that the material in the mixer trough from extruding; Before discharge door is opened, vavuum pump is extracted the air in the gas flesh seal out by the escape pipe and the interface of giving vent to anger, gas flesh seal is close on the holder, thereby away from discharge door, can not scratch the sealing of gas flesh when preventing the discharge door opening and closing, reach the sealing of effective raising mixer discharge door.
The beneficial effects of the utility model are: owing to adopted technique scheme, the utility model can be under the pressure effect that compressed air produces each position that need seal of filling automatically, thereby improve the sealing of mixer discharge door effectively, simultaneously elastic sealing element is opening the door and at closing time away from discharge door, thereby the service life of improving elastic sealing element greatly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Cutaway view when Fig. 1 closes for discharge door of the present utility model.
Fig. 2 is a discharge door of the present utility model cutaway view when opening.
Among the figure: 1, pneumatics pump, 2, air inlet pipe, 3, intake interface, 4, holder, 5, gas flesh seal, 6, discharge door, 7, trough, 8, the interface of giving vent to anger, 9, escape pipe, 10, vavuum pump.
The specific embodiment
Embodiment is: pneumatics pump 1 links with gas flesh seal 5 by air inlet pipe 5 and intake interface 3, gas flesh seal 5 is fixed on the trough 7 near discharge door 6 all around by holder 4, simultaneously, also connecting the interface 8 of giving vent to anger on the gas flesh seal 5, vavuum pump 10 links with gas flesh seal 5 by the escape pipe 9 and the interface 8 of giving vent to anger.After discharge door 6 is closed, the Compressed Gas that pneumatics pump 1 produces is full of in the gas flesh seal 5 by air inlet pipe 2 and intake interface (3), simultaneously pressure is delivered on the gas flesh seal 5, make gas flesh seal 5 under the acting in conjunction of compressed air and holder 4, produce strain, be close to discharge door 6 around, and be full of around the discharge door 6 and each corner between the trough 7, prevent that the material in the mixer trough 7 from extruding; Before discharge door 6 is opened, vavuum pump 10 is extracted air in the gas flesh seal 5 out by the escape pipe 9 and the interface 8 of giving vent to anger, gas flesh seal 5 is close on the holder 4, thereby away from discharge door 6, can not scratch gas flesh seal 5 during with 6 opening and closing of assurance discharge door, thereby improved the sealing of mixer discharge door 6, the service life of also having improved gas flesh seal 5 simultaneously.
