Abstract
The utility model relates to an over-flow and airtight screw conveyor which provides an airtight conveyor. The device comprises a barrel, a rotating shaft going through the barrel and a plurality of spiral laminas on the rotating shaft. A material discharge port with a material cover is arranged on one end of the barrel. A material discharge cover is mounted on the material discharge end and the rotating shaft goes through the material discharge cover. A first material discharge port is at the end of the rotating shaft and a baffle is mounted inside the material discharge cover. A receiving groove is positioned between the baffle and the first material discharge port. A second material discharge port for over-flow is between the baffle and the material discharge cover. The materials kept by the baffle accumulated to form a material column to seal the material discharge port; reaching a certain height, the materials will overflow from the two ends of the baffle at the two ends of the material discharge port to realize sealing effect.
Description
Technical field
The utility model relates to a kind of overflow conveyor screw, is meant especially a kind ofly to transport bulk material and need the leak free conveyor screw.
Background technology
Conveyor screw is to utilize the rotation of helicallobe to promote bulk material in the spiral cylindrical shell to travel forward and reach the purpose of convey materials, is widely used in industries such as nonferrous metallurgy, iron and steel, cement, chemical industry.At present, a kind of conveyor screw commonly used, consist predominantly of electrical motor, conveyer cylindrical shell, run through cylindrical shell turning cylinder is set, turning cylinder one end is connected with electrical motor, and the other end extends to barrel tip, is connected with some helicallobes on this turning cylinder, cylindrical shell is provided with inlet point near electrical motor one end, the cylindrical shell other end is provided with discharging opening, and turning cylinder is under the driving of electrical motor, because the loose unpacked material that the rotation of helicallobe promotes in the spiral cylindrical shell moves to discharging opening.This conveyor screw is used for transporting of ordinary material, and is not high to leak free performance requriements in the cylindrical shell.
Along with the requirement to working environment is more and more higher, particularly when processing contains the powder of pernicious gas, bad as if the sealing property of conveyer, meeting gross pollution working environment, operating personal operation, maintenance are caused very large inconvenience, have a strong impact on normal job procedure.In addition, the structure of above-mentioned conveyor screw causes this conveyor screw can not form sealing state from the inlet point to the discharging opening when convey materials, can not use under the service conditions of excellent sealing needing, and can not satisfy the requirement of technology.
The utility model content
In view of this, the purpose of this utility model is: a kind of later-model overflow sealing screw conveyer is provided, make conveyor screw have very high sealing property, also can use under the service conditions of excellent sealing needing, enlarged the range of use of conveyor screw.
The technical scheme that the utility model overflow sealing screw conveyer adopts is: a kind of overflow sealing screw conveyer, include cylindrical shell, turning cylinder, the discharge end of this cylindrical shell is provided with the discharging cover, turning cylinder runs through this discharging cover, be formed with first discharging opening in the turning cylinder end, be provided with baffle mechanism in this discharging cover body, be formed with accommodation space between this baffle mechanism, discharging cover and first discharging opening, and this baffle mechanism is provided with second discharging opening for the material overflow for solid accumulation.
Wherein, this discharging cover is provided with porthole.
Wherein, this baffle mechanism is U type structure, and its both lateral sides is connected with cover body, and this turning cylinder laterally runs through this baffle mechanism.
Wherein, this baffle mechanism upper end is provided with the notch that overflows for material.
Wherein, be connected with the some baffle plates that block notch on this baffle mechanism.
The beneficial effects of the utility model are: a kind of simple and effective structure is provided, has solved the difficult problem of conveyor screw poor sealing performance.
Description of drawings

Fig. 2 is the cutaway view of the utility model overflow sealing screw conveyer along A-A;
Fig. 3 is the discharge end part sectional view of the utility model overflow sealing screw conveyer;
The specific embodiment
In order to clearly demonstrate the inner structure of the utility model overflow sealing screw conveyer, now cooperate and illustrate, referring to accompanying drawing 1, this overflow sealing screw conveyer includes electrical motor 1 successively, turning cylinder 2, cylindrical shell 5, this electrical motor 1 connects turning cylinder 2, this turning cylinder 2 runs through cylindrical shell 5, be provided with inlet point 3 in the feed end place, the part that this turning cylinder is positioned at cylindrical shell is provided with some helicallobes 4, this conveyor screw rotates by the direct motor drive turning cylinder, and move to discharge end by inlet point by helicallobe 4 convey materials, this partial content is the content known of technical field for this reason, belongs to prior art and does not do tired stating at this.
Of the present utility model focusing on is provided with discharging cover 6 in the discharge end of this overflow sealing screw conveyer, and turning cylinder 2 runs through this discharging cover 6.As shown in Figure 2, this cover body upper end is provided with first porthole 61, second porthole 62, at any time the running condition of the material in the cover body is monitored or the part in the cover body is keeped in repair in order to the staff.
These turning cylinder 2 ends are formed with first discharging opening 9, add material in inlet point 3, and material is transported to discharge end by the effect of spiral blade of spiral conveyer 4 from inlet point, overflows through first discharging opening 9.
Be provided with U-shaped baffle plate 7 in this discharging cover body 6, this U-shaped baffle plate 7 is coated on turning cylinder 2 bottoms, upwards form the U-shaped structure, because these U-shaped baffle plate 7 bottoms are to the coating effect of turning cylinder 2 terminal bottoms, material can not directly overflow through first discharging opening 9, and is piled up in the accommodation space 10 of this baffle mechanism and the formation of turning cylinder upper end.
Has certain interval between these U-shaped baffle mechanism 7 upper ends and the discharging cover, this gap is second discharging opening 11 for the material overflow, 11 size of this second discharging opening is to set according to the flow of actual material, solid accumulation exactly overflows in the cover body through second discharging opening 11 after a certain amount of, and inner barrel has been formed the leak free effect, and material finally flows out outside the cover via the 3rd discharging opening 12.
In addition, as shown in Figure 3, these U-shaped baffle plate 7 upper ends are provided with the overflow notch 13 of may command material overflow height, the function of this notch is to realize by the some baffle plates 8 that are arranged on this notch, because the quantity of baffle plate 8 can be adjusted, like this, just can be according to desired different force value, adjust the height of overflow outlet, thereby satisfy the requirement of technology.
Said structure has formed solid accumulation in the accommodation space 10, and solid accumulation causes material to form conveyer in-to-in plugging action via the overflow of second discharging opening, has realized the sealing property of conveyor screw.This structure, the very effective sealing function of finishing conveyor screw.
The utility model provides a kind of structure of preferable helixseal conveyer, it focuses on the improvement to discharging opening, be provided with discharging cover body, U-shaped baffle plate, overflow notch, baffle plate and porthole etc. at the discharging opening place, the stock column that material itself is formed naturally by these mechanisms carries out effective seal to conveyor screw, and by the adjusting of stock column height being satisfied the requirement of different sealing pressure.
