Abstract
本实用新型提供一种用于轻质碳酸钙干法活化生产中的无扬尘储料罐。包括罐体，罐体的顶部设有进料口，罐体的底部与出料口之间设有向上倾斜的螺旋输送器；罐体的上端与缓冲罐相连通，罐体的出料口处设有与罐体连通的回流管。本实用新型结构简单，操作方便，将原有储料罐进行改进，在储料罐上增设了缓冲罐和回流管，避免了储料罐在进料、出料过程中，罐内气体逸出将超细颗粒带出造成对大气的扬尘污染。
The utility model provides a dust-free storage tank used in the dry activated production of light calcium carbonate. Including the tank body, the top of the tank body is provided with a feed port, and an upwardly inclined screw conveyor is provided between the bottom of the tank body and the discharge port; the upper end of the tank body is connected with the buffer tank, and the discharge port of the tank body is There is a return pipe communicating with the tank body. The utility model has the advantages of simple structure and convenient operation. The original storage tank is improved, and a buffer tank and a return pipe are added to the storage tank, so as to avoid the escape of gas in the tank during the feeding and discharging process of the storage tank. The ultrafine particles are taken out to cause dust pollution to the atmosphere.
Description
Technical field
The utility model relates to a kind of storage equipment in the precipitated calcium carbonate dry activation is produced, especially a kind of no airborne dust storage tank.
Background technology
In existing precipitated calcium carbonate dry activation was produced, the calcene (hereinafter to be referred as calcium activated) that obtains after activated was stored in earlier in the storage tank, calcium activated is divided in the required packaging bag again; But; Owing to when packing, have the slit between the discharging opening of storage tank and packaging bag, therefore when calcium activated flowed into packaging bag, the interior gas of bag can carry the calcium activated dust and between the slit of sack, overflow; Produce airborne dust, cause aerial contamination.
The utility model content
The technical matters that the utility model will solve provides and a kind ofly can reduce the storage tank that air-polluting does not have airborne dust.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of no airborne dust storage tank, comprise tank body, and the top of tank body is provided with inlet point, is provided with acclivitous auger loader between the bottom of tank body and the discharging opening; Its key is: the upper end of tank body is connected with expansion tank, and the discharging opening place of tank body is provided with the counter flow pipe that is communicated with tank body.
Be provided with the check valve that gas is flowed to expansion tank from tank body in above-mentioned tank body and the pipeline that expansion tank is connected.
The top of above-mentioned expansion tank is ultra-fine filter cloth.
Above-mentioned counter flow pipe is located at the outside of discharging opening, its bottom and discharging opening and together, the other end is connected with the tank body upper end, be provided with in the reflux line make gas from counter flow pipe to the mobile check valve of tank body.
Adopt the beneficial effect that technique scheme produced to be: the utility model is simple in structure, and is easy to operate, and original storage tank is improved, and on storage tank, set up expansion tank and counter flow pipe, eliminated the dust pollution that in charging, discharging process, causes.When in tank body, importing material by inlet point, the tank body internal pressure increases, the check valve SELF CL of counter flow pipe; The check valve that is communicated with expansion tank is opened automatically, and gas flows into expansion tank, again through ultra-fine filter cloth exhaust to atmosphere; And the dust that carries in the gas filtered, avoided dust pollution; When starting the auger loader discharging, the tank body internal pressure reduces, and is communicated with the check valve SELF CL of expansion tank, and the check valve of counter flow pipe is opened automatically, and the gas of accepting in the packaging bag of material is flowed in the tank body by counter flow pipe automatically, has avoided dust pollution.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1, tank body, 2, expansion tank, 3, auger loader, 4, counter flow pipe, 5, inlet point, 6, discharging opening, 7, check valve, 8, ultra-fine filter cloth, 9, check valve, 10, packaging bag.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Be illustrated in figure 1 as the structural representation of the utility model.Be provided with acclivitous auger loader 3 between the bottom of the tank body 1 of the utility model and the discharging opening 6, the bottom of tank body 1 is connected with the top of auger loader 3, and the end of auger loader 3 is connected with discharging opening 6; The upper end of tank body 1 is connected with expansion tank 2; In the pipeline that is communicated with the two, be provided with check valve 7; Check valve 7 makes gas to flow to expansion tank 2 from tank body 1; The top of expansion tank 2 is ultra-fine filter cloth 8, and ultra-fine filter cloth 8 makes the gas exhaust to atmosphere in the expansion tank 2, and the dust that carries in the gas is filtered; Discharging opening 6 places of tank body 1 are provided with the counter flow pipe 4 that is communicated with tank body 1.Counter flow pipe 4 is located at the outside of discharging opening 6, its bottom and discharging opening 6 and together, the other end is connected with tank body 1 upper end, be provided with in the reflux line make gas from counter flow pipe 4 to the mobile check valve 9 of tank body 1.
When charging, check valve 9 is closed, and check valve 7 is opened, and the gas in the tank body 1 gets in the expansion tank 2, and through ultra-fine filter cloth 8 exhaust to atmospheres, the dust that carries in the gas is trapped in the expansion tank 2 again, produces airborne dust when having avoided charging; When discharging, check valve 7 is closed, and check valve 9 is opened, and the gas in the packaging bag 10 gets in the tank body 1 through counter flow pipe 4, produces airborne dust when having avoided discharging.
