Abstract
The utility model relates to an air exhaust and dust-removing device for a ceramic press die. The air exhaust and dust-removing device comprises multiple press dies, a gas-water separator, a power device, a pressure vacuum buffer device for vacuumizing a cavity to make the cavity stay within the high vacuum range, and gas recovery devices respectively connected with the multiple press dies. The power device and the gas-water separator are connected. The vacuum buffer device is connected with the gas-water separator and the gas recovery devices. Each gas recovery device includes a buffer tank which is successively connected with a switch valve, a plurality of filters and one corresponding press die via an air pipe. A control valve connected with an external air source is disposed between each filter and one corresponding press die. The greatest advantages of the air exhaust and dust-removing device is that through value changes of pressure inside the pressure vacuum buffer device, air in ceramic powder material in the multiple press dies is actively and rapidly absorbed before pressing, and thus the power molding speed is increased.
Description
Technical field
The utility model relates to vacuum pumping hardware, refers more particularly to a kind of air exhaust and dust arrester for ceramic press mould.
Background technology
Ceramic powder in ceramic press mould is in compressing process, owing to containing a large amount of air in ceramic powder.In the process of compacting, the air in ceramic powders also can be compressed, and compressed air in ceramic powders after press die release can expand gradually, recovers reset condition.Just because of compression, the expansion characteristics of air, make it there is very large destruction to powder pressing forming.Therefore, the infringement compressing Bear-grudge body of pottery being caused in order to solve the expansion of the air in ceramic powders, what traditional measures was taked is suppressed and slowed down pressure removal speed and eliminate the compression of air, the impact of expansion characteristics on powder compacting Bear-grudge body by substep, whole forming process speed is slow, and efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of vacuum exhaust of ceramic press mould and dust arrester reasonable in design, simple in structure, that before moulded section, the air in mould is initiatively discharged are fast provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of ceramic press mould air exhaust and dust arrester, comprise many group press dies, moisture trap, power set, gas concentration unit for chamber being evacuated to the pressure vacuum buffer unit within the scope of high vacuum and being connected with this many groups press die respectively, wherein these power set are connected with moisture trap, and described vacuum buffer device is connected with described moisture trap, gas concentration unit respectively; Described gas concentration unit comprises a surge tank, and this surge tank is connected with switch valve, several filters and press die successively by tracheae, is also provided with the control valve being connected with external air source between its middle filtrator and press die.
Further, described pressure vacuum buffer unit comprises a buffering gas tank and electrovacuum contact pressure table, and wherein this electrovacuum contact pressure table is located on this buffering gas tank.
Further, described moisture trap is also provided with exhaust outlet and hydrologic cycle cooling system.
Further, there is source for one for the vacuum that vacuum is provided in described power set.
The utility model is adopting after such scheme, its great advantage is that many gas concentration unit one end for the air that extracts press die powder are connected with many groups press die respectively, the other end is connected with a pressure vacuum buffer unit, change by the force value in this pressure vacuum buffer unit the air that many groups press die is pressed down in the ceramic powder in front mold and carry out active absorption fast, improve powder compacting speed; And open by the control valve being connected with external air source, tracheae and the dust that completes in the die head after moulded section are carried out to blowback, eliminate dust.The utility model is simple in structure, and moulded section speed is fast, and working stability is reliable.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Shown in accompanying drawing 1, a kind of ceramic press mould air exhaust and dust arrester described in the present embodiment, this device comprises many group press dies 1, moisture trap 2, power set 3, for chamber is evacuated to the pressure vacuum buffer unit 4 within the scope of high vacuum and be connected with this many groups press die respectively for extracting the gas concentration unit 5 of air of powder of press die 1.Every group of gas concentration unit 5 comprises a surge tank 501 for buffer memory press die dust air, and this many groups surge tank 501 is connected with many groups press die 1 with Pneumatic valve 502, two dust filter units that are connected in series 503 successively by tracheae respectively.Wherein, be also provided with the electromagnetic switch valve 504 being connected with external air source between filter 503 and press die 1, described pressure vacuum buffer unit 4 comprises that one is provided with the buffering gas tank 401 of electrovacuum contact table 402.
Wherein, these power set 3 adopt vavuum pump, can certainly adopt other vacuum that vacuum is provided that source occurs, not to be limited.Described moisture trap 2 provides power by this vavuum pump, moisture trap 2 housing tops are also provided with exhaust outlet 201, and moisture trap 2 inside are also provided with the hydrologic cycle cooling system for cold gas separator 2 water temperature inside, and this hydrologic cycle cooling system feeds water by outside automatic water-replenishing device.This vavuum pump moves by electrical control gear control; concrete; before press die 1 starts to press down; vavuum pump action; buffering gas tank 401 and surge tank 501 are vacuumized; along with the pressure drop (cushioning can the reach-0.098mpa of vacuum of gas tank in the present embodiment) of buffering gas tank 401 and surge tank 501 inside; while reaching the minimum pressure value that electrovacuum contact pressure table 402 sets; electrovacuum contact pressure table 402 feedback signal, to electrical control gear, is controlled vavuum pump and is shut down.Simultaneously, Pneumatic valve 502 is due to the poor conducting of pressure at two ends, air in press die 1 in Ceramic Dust is in tracheae, filter 503, Pneumatic valve 502, surge tank 501 are collected to buffering gas tank 401, along with the pressure in buffering gas tank 401 raises, while reaching the maximum pressure value that electrovacuum contact pressure table 402 sets, electrovacuum contact pressure table 402 feedback signal is to electric control system, electric control system is sent control signal, the action of control vavuum pump, air in buffering gas tank 401 and surge tank 501 is extracted out, and Pneumatic valve 502 ends simultaneously.
In the time that electric control system detects the molding of press pressing mold, electric control system is sent control signal, control electromagnetic switch valve 504 conductings, the gas tank that external air source is connected to pressing mold die head and with pressing mold die head carries out blowback, eliminate the dust that die head and tracheae contain, so far complete the process of a vacuum exhaust and dedusting.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
