Material is pushed forward after entering in housing by rotating helical blade, the charge door by discharge port into reaction kettle, in reaction kettle
Gas along charge door flow back when, since helical blade and reducer inner walls are fitted close, and thing is full of between helical blade
Material, has completely cut off gas backstreaming to the route of hopper, material caused by reducing gas backstreaming pollutes.
Further, the inner walls coating polytetrafluorethylecoatings coatings of the reducer, to increase lubricity, reduce helical-blade
The abrasion of piece and housing.
Further, exhaust pipe is also set up on the housing, the discharge port is placed in the bottom of housing tail end so that material arrives
Up to reaction kettle can be entered during discharge port under Gravitative Loads；The exhaust pipe is placed in the top of housing tail end, on the exhaust pipe
Filtration apparatus is set, and the gas of reaction kettle discharge enters exhaust pipe after discharge port enters housing and discharged after being filtered.
Further, bleeding point is additionally provided with the exhaust pipe, is communicated for the air exhauster with peripheral hardware, with abstraction reaction kettle
Gas, avoid gas backstreaming to hopper.
The technique effect of utility model：（1）The anti-return helical feeder of the utility model, relative to the prior art, shell
Reducer is set in the middle part of body so that helical blade is close to set with reducer inner walls, by material and helical blade to gas
Return flow path carry out isolation blocking so that anti-return helical feeder possesses lock airway dysfunction, reduces gas backstreaming to hopper
Risk；（2）The setting of polytetrafluorethylecoatings coatings, increases the lubricity between helical blade and inner walls, prolongs the service life；
（3）Exhaust pipe and filtration apparatus are engaged so that the gas of reflux is moved to exhaust pipe, and is discharged after being filtered by filtration apparatus；
（4）The setting of bleeding point so that reaction kettle can be exhausted by air exhauster.
Brief description of the drawings
The utility model is described in further detail with reference to Figure of description：
Fig. 1 is the utility model anti-return helical feeder and hopper, the assembling structure schematic diagram of reaction kettle；
Fig. 2 is the sectional view along A-A in Fig. 1.
In figure：Hopper 1, housing 2, motor 21, reducing piece housing 22, helical blade 23, shaft 24, polytetrafluorethylecoatings coatings
25, reaction kettle 3, feed pipe 31, filtration apparatus 32, bleeding point 33, exhaust pipe 34, Pneumatic butterfly valve 35, reducer 4.
Embodiment
As shown in Figure 1 to Figure 2, the anti-return helical feeder of the present embodiment includes embodiment 1：Tubular shell 21, along cylinder
Shaft 24 that shape housing 2 is axially set, the helical blade 23 along the spiral setting of 24 outer wall of shaft, the front end of tubular shell 2 are set
The motor 21 coordinated with the transmission of shaft 24, rotates for drive shaft 24 and helical blade 23；Tubular shell is set at the top of 2 front end
Feed inlet, helical blade 23 and 2 inner wall clearance fit of housing are put, and the middle part of housing 2 sets reducer 4, the reducing of reducer 4
22 internal diameter of piece housing is adapted with the outside diameter of helical blade 23 so that the helical blade 23 is close to the inner wall of the reducer 4
Set, 22 inner wall of the reducing piece housing coating polytetrafluorethylecoatings coatings 25 of reducer 4, to increase lubricity, reduce helical blade
23 and the abrasion of reducing piece housing 22；The tail end bottom of housing 2 sets discharge port.
During assembling, the hopper 1 for holding material is placed in the top of anti-return helical feeder feed inlet, under hopper 1
Material mouth is tightly connected through ring flange and anti-return helical feeder feed inlet so that the material in hopper 1 can drop down onto anti-return down
In the tubular shell 2 of helical feeder；Through 31 phase of feed pipe between anti-return helical feeder discharge port and 3 charge door of reaction kettle
Even so that material can enter feed pipe 31 when reaching discharge port under Gravitative Loads；Pneumatic butterfly valve 35 is set on feed pipe 31,
For controlling the opening and closing of feed pipe 31；The top of 2 tail end of housing sets exhaust pipe 34, and filtration apparatus 32 is set on the exhaust pipe 34
（Metal filtering core can be selected in filtration apparatus）, for filtering；Material during use in hopper 1 enters behind the front end in housing 2 by revolving
The helical blade 23 turned pushes forward, reaches and enters feed pipe 31 by discharge port after 2 tail end of housing, the gas edge in reaction kettle 3
When feed pipe 31 flows back, since helical blade 23 and 22 inner wall of reducing piece housing are fitted close, and it is full of between helical blade 23
Material, has completely cut off gas backstreaming to the route of hopper 1, the gas of reflux and has circulated to the less exhaust pipe 34 of air pressure, filtered through metal
Discharged after core filtering, reduce gas backstreaming and cause the possibility that material pollutes in hopper.
Preferably, being additionally provided with bleeding point 33 on exhaust pipe 34, communicated for the air exhauster with peripheral hardware, with abstraction reaction kettle
Gas in 3, avoids gas backstreaming to hopper 1.
The middle part of housing 2 of above-mentioned anti-return helical feeder sets reducer 4 so that helical blade 23 and reducing piece housing
22 inner walls are close to set, and carry out isolation blocking to the return flow path of gas by material and helical blade 23 so that anti-return is spiral
Loader possesses lock airway dysfunction, reduces gas backstreaming to the risk of hopper 1.
