Abstract
The utility model discloses a fluidization nozzle for a back-pressure type blow tank. The fluidization nozzle comprises a nozzle sleeve and a pressure spring, one end of the pressure spring is fixed on the back-pressure type blow tank, and the other end of the pressure spring penetrates through the nozzle sleeve to be connected with a nozzle cover. By means of the technical scheme, the fluidization nozzle is automatically opened by means of pressure difference between the inside of the tank and outside air pipelines when pneumatic transmission starts, and high-speed air currents formed by the nozzle can impact materials in the tank along the inclined surface of the nozzle cover to enable the materials in the tank to form completely fluidized states. The fluidization nozzle for the back-pressure type blow tank is good in sealing performances, easy to overhaul and capable of reducing using costs, adapting to existing conveying production environments of high weight materials and guaranteeing safe and efficient operating of material conveying systems.
Description
Technical field
The utility model relates to a kind of fluidisation nozzle, particularly a kind of fluidisation nozzle that is used for back pressure type transmission jar.
Background technology
In the existing strength transportation art, sending jar is the most common load transfer device.Domestic common transmission jar in usefulness mainly takes the bottom that the mode of fluidisation dish is installed, and the pore through the fluidisation dish carries out fluidisation to material.But reach more greatly under the bigger situation of granular material proportion in the transmission tank volume, traditional fluidisation dish is relatively poor to sending jar interior goods fluid effect, the output out of reach production requirement far away that strength is carried.Therefore under the situation of present power plant coal variation, be badly in need of the fluid effect that sends in the jar is improved.
The utility model content
The purpose of the utility model is, a kind of fluidisation nozzle that back pressure type sends jar that is used for is provided.This fluidisation nozzle reaches more greatly under the bigger situation of granular material proportion in the transmission tank volume and uses, and can keep material high speed fluidisation, and make the goods fluid better effects if.
The technical scheme of the utility model: a kind of fluidisation nozzle that is used for back pressure type transmission jar, comprise nozzle sleeve and pressure spring, an end of pressure spring is fixed on back pressure type and sends on the jar, and the other end of pressure spring passes nozzle sleeve and is connected with nozzle cover.
In the aforesaid fluidisation nozzle, described pressure spring is connected with described nozzle cover through connecting rod.
In the aforesaid fluidisation nozzle, described nozzle cover has the inclined-plane that joins with nozzle sleeve.
In the aforesaid fluidisation nozzle, said inclined-plane becomes 15 ° of angles with the nozzle cover bottom surface.
In the aforesaid fluidisation nozzle, described nozzle sleeve, nozzle cover, pressure spring all adopt stainless steel.
Compared with prior art, the utility model is configured for the fluidisation nozzle that back pressure type sends jar through comprising that nozzle sleeve, pressure spring, nozzle cover link together.Utility model adopts the said structure scheme, and the strength conveying relies in the jar when beginning and the difference of pressure between the external air duct is opened automatically, and the high velocity air of nozzle formation can make a jar interior material form complete fluidized state along the inclined-plane impact jar interior material of nozzle cover.Good, the easy maintenance of the utility model sealing structure property reduces use cost; Can adapt to existing high specific gravity mass transport production environment; Can keep material-transporting system safety, operation efficiently.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in the accompanying drawing: 1-nozzle sleeve, 2-nozzle cover, 3-connecting rod, 4-pressure spring, 5-inclined-plane, 6-fluidisation pipe, 7-nut, 8-guide pin bushing, 9-screw thread.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind ofly be used for the fluidisation nozzle that back pressure type sends jar, constitute as shown in Figure 1ly, comprise nozzle sleeve 1 and pressure spring 4, an end of pressure spring 4 is fixed on back pressure type and sends on the jar, and the other end of pressure spring 4 passes nozzle sleeve 1 and is connected with nozzle cover 2.
Pressure spring 4 is connected with nozzle cover 2 through connecting rod 3.
Nozzle cover 2 has the inclined-plane 5 that joins with nozzle sleeve 1.
Inclined-plane 5 becomes 15 ° of angles with nozzle cover 2 bottom surfaces.
Nozzle sleeve 1, nozzle cover 2, pressure spring 4 all adopt stainless steel.
One end of pressure spring 4 is fixed on back pressure type through nut 7 and sends on the fluidisation pipe 6 of jar.
Inclined-plane 5 is the inclined-plane of machine up, keeps the degree of finish of finished surface.
During installation, fluidisation pipe 6 is extend in the jar from sending the tank top, but must keep a jar interior fluidisation pipe 6 to be arranged in tank body central authorities, tolerance is no more than 2mm.Use 3 angle steel near the nozzle top of sending pot bottom and support, and nozzlend must with the inner tank wall full weld.At is used for that nozzle sleeve 1 is connected the screw thread 9 of fluidisation pipe 6 should be complete, guarantees that nozzle sleeve 1 can steadily be loaded onto and loosening.One end of pressure spring 4 is fixed on through nut on the tube wall of fluidisation pipe 6, and pressure spring 4 other ends are through connecting rod 3 connection inclined-planes 5.Connecting rod 3 is arranged with guide pin bushing 8, and it is spacing that connecting rod 3 carries out level by guide pin bushing 8.
When using; Rely in the jar and between the external air duct when strength is carried beginning and form difference of pressure; According to the pressure reduction principle, the nozzle cover 2 on band inclined-plane is opened, and gas sprays at a high speed through nozzle; The high velocity air that nozzle forms can impact a jar interior material along the inclined-plane of nozzle cover, makes a jar interior material form complete fluidized state.Goods fluid resets nozzle cover 2 through pressure spring 4 after finishing.
