Description
Technical field
The utility model is related to chemical industry pump technical field, more particularly to a kind of chemical pump filter device.
Background technology
Chemical pump is a kind of liquid material conveying equipment for being widely used in chemical field, mainly based on centrifugal pump, when
When containing a large amount of solid impurities in liquid, these impurity can constantly hit impeller, make impeller surface Accumulative damage, influence work effect
Rate, when serious even clogging impeller channel, the outlet pressure of pump is substantially reduced, while the sealing that impurities in liquid can also be to pump
Impact, leak pump, so, often install filter additional in the charging aperture of chemical pump, existing filter is past
Toward by-pass filtration or secondary filtration, poor filtration effect, and needs manually impurities removal is used, lavish labor on.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design, simple in construction, chemical pump filtering dress of easy production operation
Put, including：Charging aperture, the first filter chamber, the first screen pack, screen pipe, the second screen pack, Z-type pipe, the second filter chamber, chemical industry
Pump, discharge nozzle, the 3rd screen pack, blow-off pipe, collecting tank；The charging aperture is arranged on the left of the first filter chamber, first mistake
Filter screen is arranged on the right side of the first filter chamber, and the collecting tank is arranged on the first filter chamber bottom, and the screen pipe is truncated cone-shaped, institute
State screen pipe left end to be connected with first filter chamber's right-hand member, the first screen pack is located at screen pipe and the first filter chamber junction, described
Screen pipe right-hand member on the left of the second filter chamber with being connected, and second screen pack is arranged on screen pipe and the second filter chamber junction,
First filter chamber bottom right is communicated to collecting tank by blow-off pipe, and the screen pipe left end is communicated to receipts by blow-off pipe
Collect tank, the Z-type pipe is arranged on inside the first filter chamber, the Z-type pipe left end is connected to the second screen pack, the Z-type pipe is right
End is connected to discharge nozzle, and the Z-type pipe right-hand member is provided with the 3rd screen pack, the discharge nozzle right-hand member connection with discharge nozzle junction
To chemical pump.
Further, first screen pack is circular and identical with the big nose circle diameter of screen pipe.
Further, second screen pack is circular and identical with the small nose circle diameter of screen pipe.
Further, the Z-type pipe left end is round exit, and right-hand member is round exit, and left end round exit diameter
For 1.5 times of right-hand member round exit diameter.
Further, the 3rd screen pack is circular and identical with Z-type pipe right-hand member round exit diameter.
Further, the first screen pack mesh number is less than the second screen pack mesh number, and the second screen pack mesh number is less than the 3rd
Screen pack mesh number.
Further, the angle between the screen pipe bottommost bus and horizontal line is 35-40 °.
Compared with prior art, the beneficial effects of the utility model are：A kind of chemical pump filter device of the utility model, knot
Structure is simple, and easy to manufacture, processing cost is low, and the utility model can mitigate labor strength, improves operating efficiency, by by the
One screen pack and the second screen pack are separately positioned on the big nose circle and small nose circle of screen pipe so that thick flow velocity is fast for the first time, and second
Secondary filtration flow-rate reduction, can greatly improve filter effect, by using the screen pipe of truncated cone-shaped, and optimize screen pipe most
Bottom bus and horizontal angle, enable to the impurity filtered out slowly to flow backward to end-of-the-pipe, enter from blow-off pipe
In collecting tank, blowdown is more thorough, it is to avoid during conventional flat filtering, because large granular impurity was expressed to by too fast flow velocity
Filter screen opposite side, so that filter effect can be reduced greatly, filtering sets Z-type pipe and the 3rd screen pack, can further improve
Filter effect.
