Description
Technical field
The present invention relates to cement-packing plant, particularly the discharge device on cement-packing plant.
Background technology
Be provided with screw feeder on cement-packing plant in discharge device, the transmission of power of motor is to screw feeder, and under the rotation of screw feeder, the cement in feed bin out enters cement package bags from discharging opening.The power of this device comes from motor, its complex structure, and cost is high, and screw feeder also easily damages, and changes cumbersome.During maintenance, fixedly the left and right blind flange of screw conveyor shaft disassembles, thereby makes maintenance very inconvenient.In addition, producing cement production enterprise has requisite air compressor, and this machine is generally round-the-clock running, but on the low side to its degree of utilization.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, the discharge device on installation, maintenance and cement-packing plant easy to use.
Technical solution of the present invention is completed like this, discharge device on cement-packing plant, include discharge bin, sealed at both ends left blind flange, the right blind flange of being fixedly connected with of discharge bin, being provided with in described discharge bin can be to jet air jet system in discharge bin, air inlet pipe on air jet system is with left blind flange tight weld or together with being screwed onto, the admission port of air inlet pipe is located at the left side of left blind flange, and air jet system is provided with a plurality of fumaroles.Described air jet system is that on gas ejector pipe and gas ejector pipe, set a plurality of fumaroles form, and air inlet pipe is together with gas ejector pipe is screwed onto or be integrated, and the gas ejector pipe right-hand member is welded with cover plate.Fumarole be distributed on gas ejector pipe around.The right-hand member of gas ejector pipe is close to right blind flange.Gas ejector pipe is located at the centre of discharge bin.Described air jet system is that on gas ejector pipe and gas ejector pipe, set a plurality of fumaroles form, and air inlet pipe is together with gas ejector pipe is screwed onto or be integrated, and the gas ejector pipe right-hand member is together with right blind flange welding or being screwed onto.The area summation of all fumaroles is equal to or less than the inner circle area of gas ejector pipe.Be arranged with four rows or six row's fumaroles on described gas ejector pipe.
Technique effect of the present invention is: because being evenly equipped with fumarole on the gas ejector pipe in discharge bin, under the blowing of air-flow, the cement at inlet point place is entered in discharge bin, make the cement in discharge bin out enter very easily cement package bags in discharging opening, so this device is very easy to use.Because screw conveyor shaft has been replaced with gas ejector pipe, do not need to use motor as propulsion source, make the structure of this device become more simple; During maintenance, as long as fixedly air inlet pipe one end removes or air inlet pipe, gas ejector pipe are screwed down and can keep in repair from blind flange from blind flange, make maintenance become convenient.If the air compressor of round-the-clock running is connected with the air inlet pipe of this device, can also improve the degree of utilization of air compressor, save production cost, reduce the equipment purchasing cost, do not need to purchase separately air compressor yet.Test shows, in feed bin, cement flows out from discharging opening as long as have gas to flow in gas ejector pipe just can to make.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is the A-A cutaway view of first embodiment of Fig. 1.
Fig. 3 is the A-A cutaway view of second embodiment of Fig. 1.
Drawing explanation: 1, air inlet pipe; 2, left blind flange; 3, fumarole; 4, inlet point; 5, gas ejector pipe; 6, discharge bin; 7, right blind flange; 8, discharging opening.
The specific embodiment
By reference to the accompanying drawings the present invention is described in further detail, as shown in Figure 2, discharge bin 6 left and right of the first embodiment are sealed at both ends is bolted with the left and right flanges lid with bolt, air inlet pipe passes left blind flange 2 and with left blind flange tight weld or together with being screwed onto, air inlet pipe 1 and gas ejector pipe 5 are screwed onto together, and air inlet pipe 1 and gas ejector pipe 5 also can be an integral body; Gas ejector pipe 5 surroundings that are located in discharge bin 6 are evenly equipped with a plurality of fumaroles 3, the front and back up and down that is to say gas ejector pipe all have fumarole, gas ejector pipe 5 right-hand members are welded with cover plate, also can be provided with jetly on described cover plate, the area summation of all fumaroles on gas ejector pipe is less than or equal to the inner circle area of gas ejector pipe.Be arranged with four rows or six row's fumaroles on gas ejector pipe.For ensuring better result of use, gas ejector pipe preferably is located in the middle of discharge bin; The gas ejector pipe right-hand member is adjacent to right blind flange 7 as much as possible.During maintenance, left blind flange and air inlet pipe are removed from discharge bin get final product, perhaps gas ejector pipe is directly screwed down from left blind flange and get final product, do not need to dismantle again left blind flange.
Second embodiment of the present invention, as shown in Figure 3, together with the difference of the first embodiment was the gas ejector pipe right-hand member and right blind flange 7 welding or is screwed onto, other technical characterictic was identical with the first embodiment.
During cement-packing plant work, gas enters air inlet pipe, gas ejector pipe successively from admission port, the air-flow that forms from fumarole gas out blows off the cement of inlet point 4 in discharge bin 6, and the cement in discharge bin 6 out enter into cement package bags from discharging opening 8 under the effect of air-flow.
