Detailed Description
As shown in fig. 2 to 4, the present invention includes a device for removing impurities for lime slurry preparation, which includes: vibrating screen 1, vibrating screen 1 includes: the device comprises a box body 1-2 and a filter screen 1-3, wherein a slurry inlet 1-1 is arranged above the box body 1-2, a slag outlet 1-4 and a slurry outlet 1-5 are arranged below the box body, the filter screen 1-3 is obliquely arranged inside the box body 1-2, the higher end of the filter screen is arranged below the slurry inlet 1-1, and the lower end of the filter screen is arranged above the slag outlet 1-4; the filter screen 1-3 divides the interior of the box body 1-2 into an upper space and a lower space, the upper space is communicated with the slurry inlet 1-1 and the slag outlet 1-4, and the lower space is communicated with the slurry outlet 1-5.
In the technical scheme of the application, the filter tank 3 is arranged between the slurry outlet 1-5 and the feeding interface of the slurry storage tank, and the filter tank 3 is also arranged below the slag hole 1-4. The mixed slurry of impurities and lime slurry discharged from the slag outlet 1-4 of the vibrating screen is filtered for the second time through the filter tank 3, and the filtered lime slurry is reintroduced into the reserve tank, so that the waste of the lime slurry is greatly reduced.
The filter tank 3 includes: the tank body 3-1 and the filtering structure, the upper opening of the tank body 3-1 is arranged below the slag outlet 1-4 and the slurry outlet 1-5.
The space below the slag outlet 1-4 and the space below the slurry outlet 1-5 in the tank body 3-1 are separated based on a filtering structure; the bottom of the tank body 3-1 is positioned below one side of the slurry outlet 1-5, and a slurry outlet 3-4 is arranged; the pulp outlet 3-4 is connected with a feeding interface of the pulp storage tank. Wherein, the filtration includes: a waste residue collecting net barrel 3-3 and/or a filtering baffle plate 3-2.
In this embodiment, the filtering baffle 3-2 is disposed in the inner cavity of the tank body 3-1 at a position between the slag outlet 1-4 and the slurry outlet 1-5, the space below the slag outlet 1-4 and the space below the slurry outlet 1-5 in the tank body 3-1 are separated by the filtering baffle 3-2, meanwhile, the slag collecting net barrel 3-3 is disposed below the slag outlet 1-4 in the tank body 3-1, the slag collecting net barrel 3-3 is a barrel structure formed by net materials, and after the mixed slurry of the impurities discharged from the slag outlet 1-4 and the lime slurry falls into the slag collecting net barrel 3-3, the impurities are left in the barrel, and the slurry is discharged from the barrel wall which is full of meshes.
The shape of the filtering baffle 3-2 is adapted to the cross section of the tank body 3-1, in this application, the cross section of the tank body 3-1 is a trapezoid with a wide upper part and a narrow lower part, and as shown in fig. 5, the shape of the filtering baffle 3-2 is also a trapezoid and is installed in the inner cavity of the tank 3-1. The mesh diameter of the filtering baffle is smaller than that of the waste residue collecting net barrel, the waste residue collecting net barrel collects impurities with larger size, and the slurry discharged from the barrel is filtered again based on the filtering baffle and then is input into the slurry storage tank again. In this embodiment, the filter separator is realized based on a 50 mesh screen and the waste residue collecting net barrel is realized based on a 30 mesh screen.
Lime slurry composed of lime powder and water enters the box body 1-2 from the slurry inlet 1-1 and falls onto the filter screen 1-3, liquid falls into the space below the filter screen from the meshes of the filter screen 1-3 and flows into the tank body 3-1 from the slurry outlet 1-5; the vibrator 1-6 drives the filter screen 1-3 to vibrate, and impurities remain above the filter screen 1-3, and slide downwards based on the vibration of the filter screen, and fall into the lower tank body 3-1 from the slag outlet 1-4, because the slag collecting net barrel 3-3 is arranged below the slag outlet 1-4 inside the tank body 3-1, impurities are left in the barrel, and slurry is discharged from the barrel wall to the inner cavity of the tank body 3-1; because the filtering baffle 3-2 is disposed in the inner cavity of the tank body 3-1 at a position between the slag hole 1-4 and the slurry outlet 1-5, even if a small amount of impurities are included in the slurry discharged from the slag collecting net drum 3-3, the slurry is filtered by the filtering baffle 3-2, and only the slurry passes through the filtering baffle 3-2 and is discharged into the slurry storage tank through the slurry outlet 3-4. After the impurity in the waste residue collecting net barrel 3-3 is fully collected, the waste residue collecting net barrel 3-3 is directly lifted out of the box body 1-2 and replaced.
Because the amount of lime slurry discharged from the slurry outlet 1-5 into the tank 3-1 is much larger than the slurry discharged from the slag hole 1-4, the filtering baffle 3-2 is impacted by the lime slurry on the side of the slurry outlet 1-5, reducing the probability of clogging the mesh of the filtering baffle 3-2 by condensation of impurities from the side of the slag hole 1-4. The filter separator 3-2 meshes do not need to be cleaned frequently, so that the labor is saved, and the running cost of the system is reduced.
