Abstract
The utility model relates to a powder material tank. The powder material tank comprises a silo, a feeding pipe, a safety valve and a dust collecting machine. A powder material storing cavity is formed in the silo and communicated with the feeding pipe, and the dust collecting machine is installed between the powder material storing cavity and the outside; a buffering box is arranged on the silo and provided with an inlet and an outlet, the inlet is communicated with the upper portion of the powder material storing cavity, the outlet is communicated with the lower portion of the powder material storing cavity through a buffering pipeline, and a dust remover is arranged on the buffering box. The buffering box is arranged on the silo, in this way, air pressure generated under the pressure blinding condition can be buffered through the buffering box, due to the function of the dust remover on the buffering box, the instantaneous pressure of the powder material storing cavity will not be higher than the opening pressure of the safety valve, the safety valve will not be opened, and a powder-gas mixture will not escape through the safety valve.
Description
Technical field
The utility model belongs to vehicle for construction technical field, is specifically related to a kind of powder material tank.
Background technology
At present, the dust exhaustor that stirring station powder batch can is used is roof scrubber, in large tank top, one dust exhaustor is installed exactly.In use, the high pressure gas that contain a large amount of dust directly enter dust exhaustor, by gas after filter element filtering, are discharged in atmosphere, and dust falls back in large tank.
Under normal conditions, to the filter efficiency of roof scrubber, require lower.Roof scrubber can be in time by the Bas Discharged in powder-gas mixture, and the pressure that makes powder store chamber is less than the response pressure of safety valve; And then can make safety valve keep closing, avoid powder state material to leak.
Build the pressure under situation, requiring roof scrubber to have very high filter efficiency (filter efficiency now requiring is tens times of filter efficiency under normal conditions) could be in time by the Bas Discharged in powder-gas mixture.When the filter efficiency deficiency of roof scrubber, the pressure in powder storage chamber will be at the instantaneous response pressure higher than safety valve, safety valve will be opened, powder-gas mixture leaks by safety valve, when serious, when the pressure in powder storage chamber is excessive, also may cause powder material tank top to be torn or to raise, cause immeasurable loss, there is very large potential safety hazard.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above and a kind of powder material tank is provided.
For achieving the above object, the utility model is by the following technical solutions:
A powder material tank, comprises silo, feed pipe, safety valve and dust collecter; Described silo forms powder storage chamber, and described feed pipe communicates with powder storage chamber, and described dust collecter is arranged between powder storage chamber and the external world; Described silo is provided with a baffle-box, and described baffle-box has entrance and outlet, and described entrance communicates with the top in described powder storage chamber, and described outlet communicates with the bottom in described powder storage chamber by buffering pipe, and described baffle-box is provided with dust exhaustor.
In described baffle-box, be provided with the dividing plate of arc, on described dividing plate, be evenly equipped with a plurality of airflow holes.
The bottom of described baffle-box is bullet structure.
Described feed pipe is provided with unidirectional control inlet valve.
The utility model by being provided with a baffle-box on silo, described baffle-box has entrance and outlet, described entrance communicates with the top in described powder storage chamber, described outlet communicates with the bottom in described powder storage chamber by buffering pipe, described baffle-box is provided with dust exhaustor, like this, can the air pressure of the generation under the situation that builds the pressure be carried out to buffered by described baffle-box, simultaneously by the effect of the dust exhaustor on baffle-box, the pressure that makes powder storage chamber instantaneous can be higher than the response pressure of safety valve, safety valve just can not opened, powder-gas mixture thereby can not leak by safety valve.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the powder material tank that the utility model embodiment provides.
The specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to Fig. 1, a kind of powder material tank, comprises silo 1, feed pipe 4, safety valve 2 and dust collecter 3; Described silo 1 forms powder storage chamber, and described feed pipe 4 communicates with powder storage chamber, and described dust collecter 3 is arranged between powder storage chamber and the external world; Described silo 1 is provided with a baffle-box 5, described baffle-box 5 has entrance and outlet, described entrance communicates with the top in described powder storage chamber, and described outlet communicates with the bottom in described powder storage chamber by buffering pipe 7, and described baffle-box 5 is provided with dust exhaustor 6.
By being provided with baffle-box 5 and being provided with dust exhaustor 6 on described baffle-box 5; make this powder material tank there is double filtration and decompression; effectively reduced in described powder material tank pass through gaseous tension feeding time; the situation that causes safety valve to open because air pressure is excessive; also because the pressure at the top of powder material tank is reduced; the impact being subject to of powder tank is reduced, protected powder material tank, extended the service life of powder material tank.
Further, the bottom of described baffle-box is bullet structure.
Further, in described baffle-box 5, be provided with the dividing plate 8 of arc, on described dividing plate 8, be evenly equipped with a plurality of airflow holes.
By being provided with the dividing plate of described arc, can to air pressure, slow down further, to prevent the impact effect to baffle-box, cause the air pressure in baffle-box excessive.Because the dividing plate by described has reduced air pressure, also make the dust exhaustor on baffle-box 5 extend for 6 service lifes.
Further, described feed pipe 4 is provided with unidirectional control inlet valve.
The utility model by being provided with a baffle-box on silo, described baffle-box has entrance and outlet, described entrance communicates with the top in described powder storage chamber, described outlet communicates with the bottom in described powder storage chamber by buffering pipe, described baffle-box is provided with dust exhaustor, like this, can the air pressure of the generation under the situation that builds the pressure be carried out to buffered by described baffle-box, simultaneously by the effect of the dust exhaustor on baffle-box, the pressure that makes powder storage chamber instantaneous can be higher than the response pressure of safety valve, safety valve just can not opened, powder-gas mixture thereby can not leak by safety valve.，
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
