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
The 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, with the vacuum is to filter power to extract filter pulp in the groove by rotary drum, thereby forms filter cake on the filter medium surface.Filter pulp in the groove is because the influences such as impact of agitator, the blowing of cleaning filter screen, turnover material cause filter pulp rapid fluctuation in the groove inevitably, and filter pulp is easy to come out in the splash of the position of material trough open front, produces " spattering the liquid phenomenon ".The slurries splash is understood the water content that increases filter cake to the filter cake of removal, the slurries splash can be polluted operationlocation, corrosion peripheral equipment outside machine, also wasted material simultaneously, has increased production cost.
The prior art scheme 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 as shown in Figure 1.But in the equipment long-time running, find, in order to change filter medium, above-mentioned liquid barrier must keep enough gaps with the rotary drum cylindrical, so can't effectively stop the ejection of filter pulp in the filter pulp groove, result of use is very poor, reduce filter pulp liquid level in the groove thus, directly have influence on the output and the quality of filter, sometimes in addition since on the filter medium filter cake thickness that adheres to inhomogeneous, produce " sudden and violent empty " and packing phenomenon, cause rotary-drum vacuum to leak, filter can't normally move.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of novel liquid-blocking device that can better stop the 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 the slurries cell wall on one side, another side is near the filter medium on the rotary drum, liquid barrier is hinged and connected on the slurries cell wall on one side, also be provided with jockey on the liquid barrier, this jockey one end and liquid barrier are hinged, and the other end is connected with support on being fixed on the 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 the support by 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 the slurries cell wall is provided with the auxiliary baffle plate of rectangle again, on one side this auxiliary baffle plate is connected on the slurries cell wall.
Compared with prior art, the invention has the beneficial effects as follows:
The invention has the beneficial effects as follows that this device can stop effectively that the filter pulp splash goes out the filter pulp groove, filter filter pulp groove can keep higher liquid level thus, has guaranteed product yield and quality, makes filter be able to efficient running; Avoided the spatter loss of filter pulp, kept the cleaning of working environment, reduced corrosion peripheral equipment; Stable liquid level in the material trough has also alleviated the workload that the operative employee regulates.
Description of drawings
Fig. 1 is the prior art structural representation.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is a structure A-A ' cross-sectional schematic of the present invention.
Among the figure: liquid barrier 1, connecting rod 2, pull bar 3, first nut 4, support 5, hinge 6, fixed head 7, auxiliary baffle plate 8, bolt 9, second nut 10, filter medium 11, slurries cell wall 12, rotary drum 13, gap 14.
The specific embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
As Fig. 2, shown in Figure 3, a kind of novel 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 ends are connected on the slurries cell wall 12 by fixed head 7 and hinge 6, and liquid barrier 1 another side is near the filter medium 11 on the 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 that is connected on the 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 also is provided with connecting rod 2 on (1), connecting rod 2 links into an integrated entity by the bolt 9 and second nut 10 with an end of pull bar 3, the other end of pull bar 3 is provided with screw thread, and be fixed on the support 5 by first nut 4, regulate first nut 4 and can drive connecting rod 2 and pull bar 3, thereby reach the purpose of controlling liquid barrier 1 gradient, effectively regulated and control the gap between the filter medium 11 on liquid barrier 1 and rotary drum 13 cylindricals, adjust suitable after, fastening again first nut 4; When need are changed filter medium, unclamp and adjusting nut 4, allow liquid barrier 1 overturn downwards, thereby can guarantee to have enough spacings between liquid barrier 1 and the filter medium, be convenient to change filter medium; After finishing the filter medium replacing, adjusting nut 4 allows liquid barrier 1 upwards overturn, and the distance of control liquid barrier 1 and filter medium 11 is about 5mm.
