Abstract
The invention discloses a novel liquid blocking device of a rotary drum vacuum filter, which comprises a liquid blocking plate (1), a rotary drum (13) and a slurry filter tank wall (12), wherein one side of the liquid blocking plate (1) is articulated with the slurry filter tank wall (12), and another side is close to a filter medium (11) on the rotary drum (13); the liquid blocking plate (1) is also provided with a connecting device, one end of the connecting device is articulated with the liquid blocking plate (1), and the other end is connected with a support (5) fixed on the slurry filter tank wall (12). The liquid blocking device can be used for effectively blocking filter slurry from spattering out of a slurry filter tank, and a high liquid level in the slurry filter tank can be maintained, so that the yield and the quality of a product are ensured, the spattering loss of the filter slurry is avoided, and corrosion to peripheral equipment is reduced; and the stable liquid level in the slurry filter tank also reduces the adjustment work amount of an operator and benefits replacing the filter medium.
Description
Technical field
The present invention relates to a kind of rotary drum vacuum filter, be specifically related to the liquid-blocking device of rotary drum vacuum filter.
Background technology
Rotary drum vacuum filter operation principle is: the rotation rotary drum of laying filter medium is immersed in the filter pulp groove of certain liquid level, and the vacuum of take extracts filter pulp in groove as filtering power by rotary drum, thereby forms filter cake on filter medium surface.In groove, filter pulp, due to the impacts such as impact of agitator, the blowing of cleaning filter screen, turnover material, inevitably causes filter pulp rapid fluctuation in groove, and filter pulp is easy in the splash of the position of material trough open front out, produces " spattering liquid phenomenon ".Slurries splash is understood the water content that increases filter cake to the filter cake of removal, and slurries splash can be polluted operationlocation, corrosion peripheral equipment outside machine, has also wasted material simultaneously, has increased production cost.
Prior art scheme as shown in Figure 1, at steel plate by some triangle gusset supportings of filter pulp groove front inner wall welding, stops the outside splash of the inner filter pulp of filter pulp groove according to groove width.But in the long-term discovery in service of equipment, in order to change filter medium, above-mentioned liquid barrier must keep enough gap with rotary drum cylindrical, so cannot effectively stop the ejection of filter pulp in filter pulp groove, result of use is very poor, reduce thus filter pulp liquid level in groove, directly have influence on output and the quality of filter, sometimes even because the filter cake thickness adhering on filter medium is inhomogeneous, produce " cruelly empty " and packing phenomenon, cause rotary-drum vacuum to leak, filter cannot normally move.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of liquid-blocking device that can better stop filter pulp splash and be convenient for changing the rotary drum vacuum filter of filter medium is provided.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of novel liquid-blocking device of rotary drum vacuum filter, comprise liquid barrier, rotary drum and slurries cell wall, liquid barrier is connected with slurries cell wall on one side, another side is near the filter medium on rotary drum, liquid barrier is hinged and connected on slurries cell wall on one side, on liquid barrier, be also provided with jockey, this jockey one end and liquid barrier are hinged, and the other end is connected with the support being fixed on slurries cell wall.
Further technical scheme is that described jockey comprises connecting rod and pull bar, and pull bar one end is connected with connecting rod one end, and the other end is threaded and is fixed on support by the first nut, and the other end of connecting rod is connected with liquid barrier.
Further technical scheme is that the gap location top that described liquid barrier is connected with slurries cell wall is provided with the auxiliary baffle plate of rectangle, on one side this auxiliary baffle plate is connected on slurries cell wall.
Compared with prior art, the invention has the beneficial effects as follows:
The invention has the beneficial effects as follows, this device can stop that filter pulp splash goes out filter pulp groove effectively, and filter filter pulp groove can keep higher liquid level thus, has guaranteed product yield and quality, makes filter be able to high-efficiency operation; Avoid the spatter loss of filter pulp, kept the clean of working environment, reduced the corrosion to peripheral equipment; Stable liquid level in material trough, has also alleviated the workload that operative employee regulates.
Accompanying drawing explanation
Fig. 1 is prior art structural representation.
Fig. 2 is structural representation of the present invention.
Fig. 3 is structure A-A ' cross-sectional schematic of the present invention.
In figure: liquid barrier 1, connecting rod 2, pull bar 3, the first nut 4, support 5, hinge 6, fixed head 7, auxiliary baffle plate 8, bolt 9, the second nut 10, filter medium 11, slurries cell wall 12, rotary drum 13, gap 14.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
As shown in Figure 2 and Figure 3, a kind of liquid-blocking device of rotary drum vacuum filter, comprise liquid barrier 1, rotary drum 13 and slurries cell wall 12, liquid barrier 1 is connected with slurries cell wall 12 on one side, its concrete connected mode is that liquid barrier 1 one end is connected on slurries cell wall 12 by fixed head 7 and hinge 6, and liquid barrier 1 another side is near the filter medium 11 on rotary drum 13.14 tops, gap that liquid barrier 1 is connected with slurries cell wall 12 are provided with the auxiliary baffle plate 8 of the rectangle being connected on slurries cell wall 12 on one side, are used for stopping the liquid that may spray up from liquid barrier 1 and slurry tank inwall gap 14, make it be back to slurry tank.Liquid barrier is also provided with connecting rod 2 on (1), connecting rod 2 links into an integrated entity by bolt 9 and the second nut 10 with one end of pull bar 3, the other end of pull bar 3 is provided with screw thread, and be fixed on support 5 by the first nut 4, regulate the first nut 4 can drive connecting rod 2 and pull bar 3, thereby reach the object of controlling liquid barrier 1 gradient, effectively regulated and controled the gap between the filter medium 11 on liquid barrier 1 and rotary drum 13 cylindricals, adjust suitable after, more fastening the first nut 4; When need are changed filter medium, unclamp and adjusting nut 4, allow liquid barrier 1 overturn downwards, thereby can guarantee to there is enough spacing between liquid barrier 1 and filter medium, be convenient to change filter medium; Complete after filter medium replacing, adjusting nut 4, allows liquid barrier 1 upwards overturn, and controls the distance of liquid barrier 1 and filter medium 11 about 5mm.
