[technical field]

The utility model relates to the technical field of waste acid treatment, especially a kind of technical field of spent acid filter device.

[background technique]

Metallurgy needs to carry out pickling to metal surface, and the process of pickling can generate spent acid largely containing metallic particles. If spent acid is polluted the environment by direct emission, or even seriously affects the health of surrounding resident, furthermore acid starting material cannot be sufficiently sharp With also will cause waste.

Filter device is as the process device in spent acid water treatment facilities, and solid matter filters out degree pair when waste liquid filters Entire spent acid water treatment procedure plays a crucial role.The filter device of existing spent acid water process, when waste liquid is from feed liquor When mouthful entering, waste liquid will form impact force, and the quartz sand under inlet is washed open, cause dented at this, allow to play The quartz sand overall thickness of filtration reduces, and influences filter effect, in addition, when more containing solid impurity in waste liquid, filtering Speed is slower, reduces the working efficiency of filtering.

[utility model content]

The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of spent acid filter device, Neng Goutong The quartz sand that spring and elastical cloth avoid waste liquid from directly washing away input duct exit is crossed, and reversed to the waste liquid to fall one Elastic acting force, reduce the speed of waste liquid, so that the through-hole of waste liquid slowly from elastical cloth edge and thereon is leaked down, pass through upper gear Plate and lower baffle plate are symmetrically staggered, and flow out waste liquid from filter core two sides, Increase the efficiency of waste liquid filtering.

To achieve the above object, the utility model proposes a kind of spent acid filter devices, including store up acid tank, seal storage acid tank Slot cover, filter core, filter core lid, input duct and the liquid outlet pipe for sealing filter core, the storage acid tank bottom be equipped with groove, it is described Filter core is placed in groove, and the filter core is externally provided with side plate and bottom plate, is fixed with several lower baffle plates between two blocks of side plates of front and back And overhead gage, quartz sand is also filled in the filter core, the lower section of two blocks of side plates of left and right is equipped with several fluid holes, the filter Core cap includes cover board and protrusion, and spring is fixed on the two sides side wall of the protrusion, and the other end of the spring is fixed with pulling plate, Be fixed with elastical cloth between the pulling plate, the input duct passes through slot cover and filter core lid be connected to the inside of filter core, it is described out The side wall that liquid pipe road passes through storage acid tank is connected to the inside of storage acid tank.

Preferably, the lower baffle plate is consistent with overhead gage quantity and is symmetrically staggered, two most central block baffles are Overhead gage, the overhead gage are located on lower baffle plate, the bottom surface of the lower baffle plate and the top surface palette of bottom plate, the upper gear The top surface of plate and the top surface of side plate are located in same horizontal line.

Preferably, the depth of the groove is less than the distance of bottom surface to the bottom plate bottom surface of the fluid hole under being located at most.

Preferably, the cover board of the filter core lid is located on liquid outlet pipe.

Preferably, the elastical cloth is at least one layer, the elastical cloth is woven by polypropylene yarn, the elasticity Also several through-holes are set on cloth.

The utility model has the beneficial effects that the utility model avoids waste liquid from directly washing away inlet tube by spring and elastical cloth The quartz sand in road exit, and to the one reversed elastic acting force of waste liquid to fall, the speed of waste liquid is reduced, keeps waste liquid slow Slowly the through-hole from elastical cloth edge and thereon leaks down, and is symmetrically staggered by overhead gage and lower baffle plate, exists increasing waste liquid It flows out waste liquid from filter core two sides, increases the efficiency of waste liquid filtering.
