Description of drawings
Fig. 1 is the front elevation of oblique elephant trunk ash conveying device of the present utility model;
Fig. 2 is the block diagram of oblique elephant trunk ash conveying device of the present utility model.
The specific embodiment
In order better to understand the purpose of this utility model, structure and function, below in conjunction with accompanying drawing, a kind of oblique elephant trunk ash conveying device of the present utility model is done further detailed description.
As depicted in figs. 1 and 2, oblique elephant trunk ash conveying device of the present utility model comprises and unloads grey elephant trunk 1, unloads grey elephant trunk 1 and is the main element of ash conveying device of the present utility model, can be used for finishing the operations such as transhipment of dedusting ash between two ash conveying devices.In the present embodiment, unload the version that grey elephant trunk 1 adopts rectangular duct, certainly, according to actual needs, unload the arbitrary structures form that grey elephant trunk 1 also can adopt oblique elephant trunk commonly used in the prior art, as cylindrical etc.
Further, the lower shoe that the rectangle in the utility model unloads grey elephant trunk 1 is divided into two, namely comprises the first base plate 2 and the second base plate 3.Wherein, the first base plate 2 and the second base plate 3 not at grade, namely there is certain diff-H in both at the longitudinal direction that unloads grey elephant trunk 1, are specially the first base plate 2 lower, the second base plate 3 is upper.And formed blowing mouth 5 by the diff-H between the first base plate 2 and the second base plate 3 thus, blowing mouth 5 is used for grey elephant trunk 1 inside is unloaded in the gas input, realizes removing the purpose of dust stratification.Above-mentioned the first base plate 2 and the diff-H of the second base plate 3 on the longitudinal direction that unloads grey elephant trunk 1 can be determined according to wind speed, generally are preferably 5 ~ 8mm, also are that the height of blowing mouth 5 is preferably 5 ~ 8mm.
Referring to Fig. 1 and Fig. 2, the below of the second base plate 3 is fixedly installed wind-guiding case 4, can realize by modes such as welding, the air outlet of wind-guiding case 4 joins with the blowing mouth 5 that unloads on the grey elephant trunk 1, be used for by blowing mouth 5 wind being delivered into and unload grey elephant trunk 1 inside, it should be noted, the air outlet of wind-guiding case 4 with unload grey elephant trunk 1 on blowing mouth 5 be connected should guarantee closely, firm, in order to avoid leak out, cause the work efficiency of device to reduce.Wherein, for saving working space, the global shape of wind-guiding case 4 is designed to wedge shape in the present embodiment, and certainly, the shape of the wind-guiding case 4 in the utility model is not subjected to this strict restriction.
Further, also be provided with blast pipe 6 on the wind-guiding case 4, blast pipe 6 can be connected by modes such as welding with wind-guiding case 4, and blast pipe 6 joins with source of the gas, is used for being delivered into from the gas of source of the gas wind-guiding case 4, so that next step operation of device.The source of the gas of oblique elephant trunk ash conveying device of the present utility model can adopt dust pelletizing system deashing gas, and according to dust collecting process, selected pressure gas can be without oily anhydrous pressurized air or nitrogen etc.In addition, it is to be noted, the caliber of the size of wind-guiding case 4 and wind-guiding case blast pipe 6 is determined with the size of unloading grey elephant trunk 1 by the size of blowing mouth 5, also is that the required air quantity of oblique elephant trunk ash conveying device of the present utility model is determined by blowing mouth 5 and the size of unloading grey elephant trunk 1.
In addition, with reference to the accompanying drawings 1, also can be provided with source of the gas shutoff valve 7 on the blast pipe 6, preferably, source of the gas shutoff valve 7 adopts motorized valve or electromagnetic valves so that with ash-transmission system interlock control, open and close simultaneously, economize on tolerance.
The concrete operational process of oblique elephant trunk ash conveying device of the present utility model is: when ash-transmission system is opened, source of the gas shutoff valve 7 on the wind-guiding case blast pipe 6 is opened simultaneously, pressure gas enters wind-guiding case 4 by blast pipe 6, blown out along the first base plate 2 that unloads grey elephant trunk 1 with certain wind speed by blowing mouth 5 again, dedusting ash that will landing on unloading grey elephant trunk 1 base plate is accelerated to send in next collection ash conveying device, avoid the stifled ash of dedusting ash deposition, and when ash-transmission system was out of service, shutoff valve 7 was closed simultaneously.
In addition, enter in the wind-guiding case 4 for avoiding dedusting ash, the end of the second base plate 3 must exceed along the air intake direction air outlet certain-length of wind-guiding case 4, and this length is preferably 50mm.
But oblique elephant trunk ash conveying device subdivision of the present utility model is made, but also site operation is made, and the first base plate 2, the second base plate 3 and wind-guiding case 4 in the device also all can adopt the material identical with unloading grey elephant trunk 1, is generally the Q235A straight carbon steel.So device of the present utility model is not only simple in structure, easy construction, and no-movable part in the whole system, stable and reliable operation does not need to increase extra facility in the implementation process, and investment is few.Only need to inject in the guide bellows pressure gas (air or nitrogen) during the device operation, pressure gas can blow out with certain speed the crack between the elephant trunk base plate, dedusting ash to landing in the elephant trunk forms boosting and accelerating action, effectively solves the elephant trunk clogging phenomenon.
Abovely by specific embodiment the utility model is further described; but it should be understood that; here concrete description; should not be construed as the restriction to essence of the present utility model and scope; the various modifications that the one of ordinary skilled in the art makes above-described embodiment after reading this specification sheets all belong to the scope that the utility model is protected.
