Abstract
The utility model discloses an adjustable venturi applied to production of redispersible emulsion powder, which is characterized in that a hopper and a discharging pipe are of an integrated structure, and the discharging pipe is a straight pipe section. An inlet pipe section of the venturi is of a casing pipe structure, in the casing pipe structure, an axial position of an inner casing pipe in an outer casing pipe is adjustable, an inlet of the inner casing pipe serves as a contract opening, and a nozzle of the inner casing pipe forms a flaring in the outer casing pipe. The adjustable venturi is applied to a production process of the redispersible emulsion powder, can effectively improve adding speed of an anti-caking agent, and improves production capacity.
Description
Technical field
The utility model relates to the anti-caking agent delivery duct, a kind of structure that is applied in the Venturi tube in the anti-caking agent delivery duct of saying so more specifically.
Background technology
In the redispersible latex powder production procedure; Anti-caking agent and principal goods material (redispersible latex powder) are according in the fixed proportion adding system; Anti-caking agent add be for guarantee rubber powder transport before the deadline with storage process in do not lump, improve the workability of rubber powder.The interpolation speed of anti-caking agent is the bottleneck of the productive rate of the whole redispersible latex powder of control, and the adding speed that improves anti-caking agent is to improve the key of rubber powder production capacity.
The anti-caking agent addition manner that is applied at present in the redispersible latex powder production procedure mainly is divided into: mix preceding mixed back.Traditional adding mode is that mix the back, because that the back mode of mixing causes anti-caking agent to combine with rubber powder granule is bad, the anti-caking performance of rubber powder is not ideal enough, and the workability of product is also not ideal enough.In recent years, mixed mode before the rubber powder production technology progressively adopts, anti-caking agent was directly added the spray drying top of tower, and combined with rubber powder granule closely properties of product to be improved greatly through blast system.But preceding mixed arts demand is delivered to the anti-caking agent powder+the drying tower top of 23M height from ± 0.0M through pipeline; Routine is utilized fixed type Venturi mode of movement; Venturi can not be regulated according to the proportion of convey materials (anti-caking agent), causes the feeding ability low, can not satisfy arts demand; Cause rubber powder output to receive the restriction of anti-caking agent delivery speed, thereby cause the actual production capacity of device not enough.
Through test, in the existing fixed type Venturi mode of movement, carrying the anti-caking agent peak load is 200KG/ hour, can not satisfy 300KG/ hour arts demand far away.The proportion of anti-caking agent is 900g/cm
3The high density pressed powder, the blast of conveying fan is 0.8kg/cm
3, the fixed type Venturi can not be regulated suitable nozzle location according to the proportion of material, causes material to produce putty at the Venturi feed entrance point, restriction convey materials speed.
The utility model content
The utility model is the weak point that exists in the above-mentioned existing technology for avoiding; A kind of adjustable Venturi that is applied in the redispersible latex powder production is provided; To guarantee to satisfy production requirement, improve the device capbility purpose to reach at the transport efficiency of anti-caking agent.
The utility model technical solution problem adopts following technical scheme:
The constructional feature that the utility model is applied in the adjustable Venturi in the redispersible latex powder production is: hopper is set and discharge nozzle is integrated, discharge nozzle is a straight length; The import pipeline section that Venturi is set is a sleeve structure, and in said sleeve structure, the sleeve pipe axis is to adjustable positions outside for inner sleeve, and the inlet of inner sleeve is a contraction mouth, and the outlet of inner sleeve forms enlarging in the sleeve pipe outside.
Compared with present technology; The utility model beneficial effect is embodied in: the utility model can be according to the nozzle location of material ratio readjust Venturi; Convey materials speed is up to 350KG/ hour; Satisfy arts demand fully, guaranteed traffic capacity, improve the continous-stable and the constant product quality of producing.
Description of drawings
Fig. 1 is the utility model structural representation;
Label among the figure: 1 suction flange; The 2a inner sleeve; The 2b outer tube; 3 hoppers; 4 discharge nozzles; 5 discharge flanges; 6 nozzles.
The specific embodiment
Hopper 3 is set is integrated with discharge nozzle 4, discharge nozzle 4 is a straight length; The import pipeline section that Venturi is set is a sleeve structure, and in sleeve structure, inner sleeve 2a is axial adjustable positions among the sleeve pipe 2b outside, and the inlet of inner sleeve 2a is a contraction mouth, and the nozzle 6 of inner sleeve 2a forms enlarging among the sleeve pipe 2b outside.
In the practical implementation; The suction flange 1 of Venturi tube is connected with the high-pressure air hose from blower fan; Send into anti-caking agent by screw feeder in the hopper 3, discharge flange 5 is sent into anti-caking agent and principal goods material redispersible latex powder in the drying tower through delivery duct jointly.
The utility model can effectively improve the anti-caking agent addition, improves redispersible latex powder output.
Anti-caking agent for different specific weight arrives optimal transport speed through the structural accommodation of scalable Venturi.
