Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, the utility model discloses a sulphuric acid line filter, including barrel 1, sieve bend 2, inlet pipe 3, discharging pipe 5 and evacuation pipe 7, sieve bend 2 is vertical to be set up in the barrel 1, and will barrel 1 divides settling zone and filtering area into, and the space of settling zone is greater than the space of filtering area, can hold more impurity, avoids the pipe blockage, the lateral wall of settling zone is equipped with inlet pipe 3, sieve bend 2 to inlet pipe 3 is protruding, the diapire of settling zone is equipped with evacuation pipe 7, be equipped with evacuation valve 8 on the evacuation pipe 7, be equipped with on the lateral wall of filtering area discharging pipe 5, inlet pipe 3 and discharging pipe 5 are connected on former sulphuric acid pipeline, guarantee that sulphuric acid normally carries, and change to former sulphuric acid pipeline is less. Because the volume of the settling zone is large, even under the condition that the sulfuric acid impurities are more, the cleaning operation can be carried out once in about one week, and the cleaning frequency and the cleaning time are reduced. Meanwhile, the precipitated impurities can be discharged through the emptying pipe 7 and the emptying valve 8 at any time, and the convenience of cleaning is improved.

Through protruding one side with arc screen 2 to inlet pipe 3, form great buffer area between inlet pipe 3 and the arc screen 2, reduce the velocity of flow of sulphuric acid, make impurity can obtain better filtration, and the difficult direct impact arc screen 2 of pressure that comes from the sulphuric acid pipeline, guarantee the filter effect to impurity in the sulphuric acid.

The tangent line of the arc midpoint of the arc screen 2 is positioned at one side of the central line of the barrel body 1 close to the discharge pipe 5, so that the space of a buffer zone between the feed pipe and the arc screen is increased, and the filtering effect on impurities in sulfuric acid is further improved.

Further, the arc-shaped screen 2 has more filtering area compared with a plane screen, and the filtering effect on sulfuric acid is improved.

The bottom of the arc-shaped screen 2 and the top of the feeding pipe 3 are positioned at the same height. The sulphuric acid that makes the entering barrel 1 has the buffering space, can not directly impact arc screen 2, can not make impurity directly cross arc screen 2 and influence filtration efficiency under the effect of impact force.

The discharge pipe 5 is positioned at 1/4 to 1/3 of the upper end of the barrel body 1.

The feeding pipe 3 is positioned at 1/4 to 1/3 of the lower end of the barrel body 1.

In this embodiment, discharging pipe 5 is located 1 upper end 1/3 department of barrel, and inlet pipe 3 is located 1 lower extreme 1/3 department of barrel, and the speed of slowing down the sulphuric acid circulation is gone into and is gone up out under the realization, improves filtration efficiency, guarantees to filter fully to sulphuric acid, avoids blockking up the pipeline.

The feeding pipe 3 is provided with a feeding valve 4, and the discharging pipe 5 is provided with a discharging valve 6. When impurities are removed, the feeding valve 4 and the discharging valve 6 are closed, the emptying valve 8 is opened again, the filtered and precipitated impurities can be discharged in a few minutes, and finally the feeding valve 4 and the discharging valve 6 are opened to finish the operation, so that the normal sulfuric acid conveying is not influenced, the addition amount of sulfuric acid is stabilized, the acid adding uniformity is improved, and the recovery rate is ensured.

The sulfuric acid pipeline filter also comprises a Y-shaped filter 9, and the discharge pipe 5 is communicated with a feed inlet of the Y-shaped filter 9. Sulfuric acid after being filtered by the arc screen 2 is conveyed to the Y-shaped filter 9 through the discharge pipe 5, so that the probability of blockage of the Y-shaped filter 9 can be reduced, impurities above 99 percent can be removed by filtering for two times through the arc screen 2 and the Y-shaped filter 9, the problem of blockage of a rear-end pipeline is solved, and the sulfuric acid is guaranteed to be normally conveyed in the pipeline.

The Y-strainer 9 may be a prior art Y-strainer.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
