Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that embodiment is mentioned not is the qualification to the utility model.
As shown in Figure 1; A kind of slurry pressure sieve comprises tubular shell 1, is arranged at screen frame in the tubular shell 1, is arranged at the one-level screening portion 2 on tubular shell 1 top and is arranged at the loam cake 3 of one-level screening portion 2 upper ends, and the outer wall of said one-level screening portion 2 is provided with slurry inlet tube 4; This slurry inlet tube 4 is communicated with one-level screening portion 2; The bottom outer wall of said tubular shell 1 is provided with slag slurry outlet 5 and good slurry outlet 6, and the middle part outer wall of said tubular shell 1 is provided with dilution inlet tube 7, and said loam cake 3 offers exhaust outlet 11; The set inside of said one-level screening portion 2 has heavy seeds trap 8, and this heavy seeds trap 8 is provided with exhaust exit pipe 9; Said tubular shell 1 is provided with good slurry chamber 10 with the junction of good slurry outlet 6, and this is very starched chamber 10 and is communicated with the inner chamber of tubular shell 1, and said good slurry outlet 6 is very starched chamber 10 and is communicated with being somebody's turn to do.
Operation principle: slurry gets into one-level screening portion 2 through slurry inlet tube 4 tangent lines; Through centrifugal action, heavy seeds wherein is along falling into heavy seeds trap 8 in the inwall rotary course of one-level screening portion 2, and slurry is in the passage between one-level screening portion 2 entering rotors and the screen frame; Effect through rotor on the rotor; Make good slurry pass the sieve seam on the screen frame, enter into good slurry chamber 10, discharge through good slurry outlet 6.The impurity such as thick fibre bundle that do not pass sieve seam are in dropping process, and the dilution mixed diluting that sprays into dilution inlet tube 7 to improve screening effeciency, is avoided slag slurry excessive concentration simultaneously and resulted in blockage.Final the process passage drops into said tubular shell 1 bottom and forms the slag slurry not through the impurity such as thick fibre bundle of screen frame, discharges said slurry pressure through slag slurry outlet 5 and sieves.
The said slurry pressure of the utility model sieves the concentration that reduces slurry through the mode that sprays into dilution, has improved the flowability of slurry, prevents the obstruction of screen frame bottom; Guarantee the normal operation that continues of slurry pressure sieve; Reduce its maintenance cost greatly, improve screening production efficiency, practical.
The said loam cake 3 of present embodiment offers exhaust outlet 11, and this exhaust outlet 11 is provided with drain tap 12.When slurry pressure sieves the start of empty machine, through regulating exhaust outlet 11 exhausts that drain tap 12 is opened loam cake 3,, influence screening effeciency to prevent residual airs in tubular shell 1 and the one-level screening portion 2.
The said good slurry outlet 6 of present embodiment is provided with first valve 13, during good slurry in needs are discharged said tubular shell 1, can realize very starching the opening and closing of outlet 6 through regulating said first valve 13, and is easy to operate, practical.
The said exhaust exit pipe 9 of present embodiment is provided with second valve 14; Through opening second valve 14 to emit the gas of heavy seeds trap 8; Prevent that the air in the heavy seeds trap 8 from too much influencing the heavy seeds collection of heavy seeds trap 8, guarantee that heavy seeds trap 8 continues operate as normal.
Concrete, said dilution inlet tube 7 is provided with the 3rd valve 15, can constantly in tubular shell 1, spray into dilution through dilution inlet tube 7 after opening the 3rd valve 15; During shutdown, when the stop supplies dilution, close the 3rd valve 15 and can prevent that slurry from flowing backwards; Avoid slurry to get into dilution inlet tube 7, and cause dilution inlet tube 7 to stop up, simple in structure; Safe, practical.
The said slurry inlet tube 4 of present embodiment is tangent with the outer wall of said one-level screening portion 2.Outer wall tangent line along one-level screening portion 2 enters into the inside of one-level screening portion 2 to slurry from slurry inlet tube 4, thereby just has higher rotary speed when making slurry get into the inside of one-level screening portion 2, reduces the kinetic energy rejection of slurry, energy-conserving and environment-protective, and practicality is stronger.
The foregoing description is one of preferable implementation of the utility model; In addition; The utility model can also alternate manner realizes, in any conspicuous replacement under the prerequisite that does not break away from the utility model inventive concept all within the protection domain at the utility model.
