Prior art is compared, the invention has the beneficial effects as follows: it is strong, simple to operate, easy to adjust to have a working stability, lock wind reliable performance, sealing, few easy workout part, the advantage that practicability is good, except that can be used for petroleum coke powder, also can be widely used in mixing, the conveying of other granular material.
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment:
[description of drawings]
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the partial enlarged drawing I of Fig. 1.
[embodiment]
The present invention is a kind of variable-frequency delivery pump that is used for conveying petroleum coke powder, it includes the pump box 1 that is connected bottom, storage coke powder storehouse, mixing chamber 2, and the variable-frequency motor 3 that connects successively, coupling 4, bearing housing 5 and screw reamer 6, wherein screw reamer 6 is inserted in the spiral shell 7 that is located at pump box 1 one sides, being provided with one in the outlet port 71 of spiral shell 7 can be around the powder lid 9 that is positioned at rotating shaft 8 swings above the shell, described mixing chamber 2 includes the funnel 21 of top seal and is located at the horizontal air channel 22 of funnel 21 bottoms, described powder lid 9 is arranged in these funnel 21 tops, on described air channel 22, be respectively equipped with suction port 221 and fluidized gas powder outlet 222, when variable-frequency delivery pump for petroleum coke powders is installed to combustion system, they are connected with the pressure wind gas storage of the combustion system one fen gas port and the inlet of conveyer partly respectively, gas powder outlet 222 is acclivitous openings, and 45 degree are advisable to tilt.Variable-frequency delivery pump for petroleum coke powders is covered by powder lid 9 when not working, the coke powder amount that screw reamer under the openings of sizes of gas powder outlet is driven by variable-frequency motor is carried is decided, this depends primarily on rotating speed of motor, can realize even, stable fluidized gas powder like this.Variable-frequency delivery pump for petroleum coke powders is when work, variable-frequency motor is adjusted rotating speed according to the control of system program, it drives screw reamer 6 by coupling 4 and bearing housing 5 and rotates, so the coke powder in the pump box 1 is transported to the outlet port 71 of spiral shell 7, at this moment coke powder falls along funnel 21 after powder lid 9 is pushed open, then blown down to form the fluidized gas powder that mixes and export 222 and flow out, realize coke powder and compressed-air actuated mixed process from the gas powder by the pressurized air of coming in from the suction port 221 of crosspassage 22.
Shown in Fig. 1-2, the rotating shaft 51 of bearing housing 5 is passed pump box 1 and is connected with the screw axis 61 of screw reamer 6, variable-frequency motor 3 is when driving screw axis 61 rotations like this, the coke powder that occurs easily in the pump box 1 spills from the axis hole of rotating shaft 51 place pump boxs 1, this not only can cause the waste of coke powder, and the working environment around can influencing, between the rotating shaft 51 of bearing housing 5 and pump box 1, be provided with sealing configuration 20 for this reason.Sealing configuration 20 can be different structure, as modes such as seal rings.Present embodiment is as preferred implementation, it includes mechanical type, material envelope formula and three kinds of structures of sealing gland formula and uses simultaneously, it includes the axle sleeve 201 that is enclosed within the rotating shaft 51, the inside and outside gland 202,203 that is pressed in the axle sleeve both sides, be provided with the seal ring 204 and the seal ring briquetting 205 that are enclosed within simultaneously in the rotating shaft 51 outside in the shrinkage pool of gland 202, be called seal ring formula material envelope at this.In described internal gland 202, be provided with groove 2021, gland 203 is provided with the pore 2031 that leads to groove 2021 outside, described groove 2021 has been surrounded the sealing gland space by axle sleeve 201 and outer gland 203, after the air of coming in from inlet hole 2031 enters into the sealing gland space axle sleeve 201, inside and outside gland 202,203 are tightly sticked together, play the effect of sealing gland.Axle sleeve 201 and outside be closely pressed together on together by the concavo-convex circle 206 of the mazy type that is complementary between the surface of contact of gland 203, be called mechanical sealing at this.Between the inside and outside gland 202,203, between outer gland 203 and the pump box 1, get up with bolt respectively between outer gland 203 and the seal ring briquetting 205.Through after the triple seal, can prevent the leak-stopping powder basically like this.Have the oilhole 207 that is used for adding oiling agent outside on the gland 203, give the rotating shaft 51 lubricated and coolings of the bearing housing 5 of high speed rotating.
In the present embodiment, bearing housing 5 adopts single-row or double-row type selfaligning ball bearing 52 (being the double-row self-aligning ball bearing shown in the figure), selfaligning ball bearing can allow rotating shaft 51 axial floats, even supplied materials fluctuation like this, screw reamer 6 can not be stuck when running into foreign material in the pump box 1 suddenly yet, even supplied materials or discharge end are when having malleation or anti-channeling gas, also can guarantee to stablize discharging, the coke powder that screw reamer is carried is steady more, even.
It is strong, simple to operate, easy to adjust that the present invention has a working stability, lock wind dependable performance, sealing, few easy workout part, and the advantage that practicality is good except can be used for petroleum coke powder, also can be widely used in mixing, the conveying of other granular material.
