Description
Technical field
The utility model belongs to the mass transport field, relates to transmission pump, especially a kind of top-guiding type single-stage continuous transmission pump of exerting oneself greatly.
Background technology
At present, electric coal supply epitonos, electric ature of coal amount worse and worse, the ash amount is more and more.A lot of clients hope that nearby (power plant's enclosure wall is outer) carries out comprehensive application to ash, and therefore a kind of load transfer device at exert oneself greatly remote (in the 1500m) has very big potential market.
Through retrieval, do not find the publication document relevant as yet with present patent application.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, provide a kind of reasonable in design, simple in structure, carry stable and the low top-guiding type single-stage of the over-the-road expense continuous transmission pump of exerting oneself greatly.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of top-guiding type single-stage continuous transmission pump of exerting oneself greatly; Comprise feed bin, transmission pump, terminal library, conveying source of the gas and instrument air, the below of feed bin connects transmission pump through the transmission pump inlet valve, and a gas exhaust duct is installed on transmission pump; Transmission pump is communicated with terminal library through the upper draft tube road; Carry source of the gas to be communicated with transmission pump through tracheae, instrument air connects transmission pump and detects its material level, it is characterized in that: the mode of drawing on said transmission pump adopts is communicated with transmission pump through the upper draft tube road; On the upper draft tube road, bleeder valve is installed, an outlet distributing valve is installed on bleeder valve of being installed in the upper draft tube road and the upper draft tube road between the terminal library; The going to the bottom and carry source of the gas to be communicated with to be equipped with a gasification air valve of transmission pump, is communicated with the conveying source of the gas through choker relief valve in this transmission pump.
And the choker relief valve that is communicated with in said and the transmission pump is provided with three, is respectively additional air valve, main air admission valve and outlet air valve.
The advantage and the good effect of the utility model are:
1, the utlity model has remarkable energy saving effect, its air consumption only be in the market the load transfer device air consumption 1/2, transmission pump is in feed status all the time, removed that the maximum sky of consumption gas blows the stage in the course of conveying.。
2, the utility model fed distance is far away, can reach single-stage fed distance 1500m; Conveying is exerted oneself greatly, and under identical transmission pump volume, it is 2 times of exerting oneself of load transfer device in the market that this utility model equipment is exerted oneself; Diameter of conveying pipe is little, and under the identical requirement of exerting oneself, its caliber is littler by 1/3 than existing caliber.
3, the utility model pressurized air of adopting 0.8Mpa is as carrying source of the gas, and can adopt Controlled by Programmable Controller, and degree of automation is high, stable, easy to operate, and investment cost is low, and air consumption is few, is a kind of desirable material transfer equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of top-guiding type single-stage continuous transmission pump of exerting oneself greatly; Comprise feed bin 1, transmission pump 12, terminal library 4, carry source of the gas 11 and instrument air 10; The below of feed bin connects transmission pump through transmission pump inlet valve 13, and a gas exhaust duct 14 is installed on transmission pump, and transmission pump is communicated with terminal library through upper draft tube road 3; Carry source of the gas to be communicated with transmission pump through tracheae, instrument air connects transmission pump and detects its material level.
The innovative point of the utility model is:
The mode of drawing on said transmission pump adopts is communicated with transmission pump through the upper draft tube road, and bleeder valve 2 is installed on the upper draft tube road.
The going to the bottom and carry source of the gas to be communicated with to be equipped with a gasification air valve 9 of transmission pump, is communicated with the conveying source of the gas through additional air valve 8, main air admission valve 7 and the outlet air valve 6 that is provided with respectively in this transmission pump.
One outlet distributing valve 5 is installed on bleeder valve of being installed in the upper draft tube road and the upper draft tube road between the terminal library.
In the present embodiment accompanying drawing, the choker relief valve that is communicated with transmission pump is provided with three, also can be provided with 1-8 as required.
The principle of work of the utility model is:
The instant reflection material level of low stuff level switch (L1) that is positioned at the grey storehouse of transmission pump top is put signal, and the low stuff level switch (L2) in the transmission pump is not capped, and will trigger this moment to start conveying.The transmission pump bleeder valve cuts out, and inlet valve is opened, and the material by gravity unloads and is put in the transmission pump.In the process of material filling pump, the transmission pump gas exhaust duct will be opened, and make air from carry, discharge.Indicate transmission pump when the high charge level switch (H1) of transmission pump and fill up, then the gas exhaust duct of transmission pump cuts out.Through a short time delay, transmission pump is filled up fully again, at this moment, the transmission pump inlet valve cuts out.When the inlet valve and the gas exhaust duct of transmission pump are closed and sealed, and after the choker relief valve of transmission pump opened, air admission was in armored pump, and material will unload through the upper draft tube road to be put to pipeline; When material was lower than material level, the pump housing carried air distributing device and will cut out, and bleeder valve will cut out, and the outlet distributing valve is opened and continued to carry; This moment, transmission pump began charging, reached high charge level in the pump, carried INO, and when the pump internal pressure equaled manifold pressure, bleeder valve was opened, and continued to carry.
