Abstract
The utility model discloses an air intake and unloading device for vertical drying kiln hot-blast stove, comprising a blanking cone, a blanking tube, and an air inlet tube, wherein, the blanking cone is arranged at the bottom below a shell. The inner upper part of the bottom is a pyramidal face and the inner lower part of the bottom is a discharge opening. A channel is arranged between the pyramidal face and the discharge opening, and the blanking tube is arranged in the channel. The blanking cone which is made of high-temperature pouring material is arranged on the inner upper part of the bottom and the lower end of the unloading cone is connected with the upper end of the unloading tube. The air inlet tube is arranged on the lateral surface of the shell above the unloading cone and communicated with the inner of the shell. The utility model is not easy to deform or damage in cement producing process and in high-temperature working condition.
Description
Technical field
The utility model relates to a kind of parts of drying materials equipment, specifically, is the air intake device for discharging that is used for the vertical drying kiln hot-blast stove of cement production process.
Background technology
At present, the drying materials equipment that uses in cement production process is generally vertical drying kiln hot-blast stove, its air intake device for discharging is made up of blanking awl, tremie pipe and blast pipe, the blanking awl is arranged on the bottom of housing, the blanking awl is made by metal material, the conical surface of blanking awl is provided with some air vents, and the below that the lower end of blanking awl is provided with tremie pipe, blanking awl is provided with blast pipe.During work, the hot blast in the burner hearth is bored air vent by blast pipe through blanking and is entered enclosure interior, and extremely down and upward to drying by the material on many groups material sliding cone and the material spreading cone, the material of being dried falls into to glide after blanking is bored and enters the tremie pipe discharge.Because the hot blast temperature by the blanking awl reaches 400 ℃-480 ℃, easy deformation is at high temperature bored in blanking, and maintenance cost is higher; Because the metal blanking is bored under the condition of high temperature, and material easily is worn when this conical surface downslide, thereby the blanking awl life-span is short, changes frequently, and maintenance load is big, production cost is higher simultaneously.
The utility model content
The technical problems to be solved in the utility model provides a kind of air intake device for discharging of vertical drying kiln hot-blast stove, and it can be not only not yielding but also not easy to wear under the condition of high temperature.
For solving the problems of the technologies described above, the air intake device for discharging of the utility model vertical drying kiln hot-blast stove is bored by blanking, tremie pipe and blast pipe constitute, the blanking awl is arranged on the bottom of housing below, the internal upper part of bottom is shaped as the conical surface, interior bottom is a discharge opening, be provided with passage between the conical surface of the internal upper part of bottom and the discharge opening of interior bottom, tremie pipe is arranged in this passage, the blanking awl is arranged on the internal upper part of bottom, the material of blanking awl is that high temperature waters material feeding, the lower end of blanking awl joins with the upper end of tremie pipe, blast pipe be arranged on that blanking is bored on the side of upper shell and with enclosure interior communications and liaison mutually.
Because the blast pipe of the air intake device for discharging of above-mentioned vertical drying kiln hot-blast stove, be arranged on the blanking awl upper shell side and with enclosure interior communications and liaison mutually, high-temperature hot-air is not bored by blanking, but directly enter in the housing from blast pipe, to going up down material is dried, thereby high-temperature hot-air is less to the influence of blanking awl; Because the material of blanking awl is that high temperature waters material feeding, itself have high temperature resistant and anti abrasive performance simultaneously, thereby the not yielding and wearing and tearing in the high-temperature operation process of blanking awl.So the long service life of this device, maintenance capacity is little, and production cost is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1. housings among the figure, 2. material spreading cone, 3. material sliding cone, 4. secondary air channel, 5. blanking awl, 6. internal upper part, 7. bottom, 8. blast pipe, 9. tremie pipe, 10. discharge opening, 11. burner hearths.
The specific embodiment
Among Fig. 1, the inside of housing 1 is to being provided with many group material sliding cones 3 and material spreading cone 2 down, the bottom of housing 1 is provided with bottom 7, and bottom 7 internal upper parts 6 are for the conical surface, interior bottom are discharge opening 10, is provided with passage between the internal upper part 6 of bottom 7 and the discharge opening 10 of interior bottom, tremie pipe 9 is arranged in this passage.Blanking awl 5 is arranged on the internal upper part 6 of bottom 7, and in order to improve the high temperature resistant and anti abrasive performance of blanking awl 5, blanking awl 5 is watered on the internal upper part 6 that material feeding is cast in bottom 7 by high temperature, and 5 lower end is bored in blanking and the upper end of tremie pipe 9 joins.Because high temperature waters material feeding and has high temperature resistant and anti abrasive performance, the blanking awl is 5 yielding in the high-temperature operation process, material slides thereon and is difficult for being worn, thereby blanking bores 5 long service life, and maintenance capacity is little, and production cost is low.In order to reduce the influence of high temperature to blanking awl 5, blast pipe 8 be arranged on that blanking is bored on the side of 5 upper shell 1 and with housing 1 inner communications and liaison mutually.In order to improve drying efficiency, an end of secondary air channel 4 be arranged on that blanking is bored on the side of 5 upper shell 1 and with housing 1 inner communications and liaison mutually, the inside of the other end of secondary air channel 4 and the upper side of housing 1 is communications and liaison mutually.During work, the hot blast in the burner hearth 11 enters the interior bottom of housing 1 through blast pipe 8, and hot blast is to going up drying by the material on material sliding cone 3 and the material spreading cone 2 down.Directly enter the internal upper part of housing 1 simultaneously through the hot blast of secondary air channel 4,, improve the drying effect of material strengthening oven dry by the wet material of internal upper part.The material of being dried falls in the blanking awl 5, enters tremie pipe 9 from the 5 interior downslides of blanking awl again and discharges.
Claims (1)
