Abstract
The utility model discloses a washing water device of a vacuum rotary drum, which is used for making alkali. The washing water device is fixedly hung above a rotary drum washing station, and is characterized in that the device comprises a main pipe which extends along the axial direction of the rotary drum, wherein the main pipe is provided with at least one water inlet which is connected with a washing water conveying pipe and the main pipe is provided with a plurality of spray heads which are communicated with main pipe in a distant mode along the axial line of the main pipe. The utility model has the advantages that by adopting the spray heads of low pressure and small flow, the utility model enables the washing water to generate even atomizing water flow on the surface of an alkali cake, enhances the penetrability of the washing water and reduces the impact force of the washing water to the alkali cake. The washing water does not form ditch flow, the consumption of the washing water can be reduced largely and the washing water is favorable for the stabilization of the quality of pure alkali products.
Description
Technical field
The utility model relates to vacuum-type drum filter, relates in particular to the washing equipment of system alkali with vacuum-type drum filter.
Background technology
System alkali vacuum-type drum filter is to make filtered driving force with negative pressure, and filtering surface is at the continuous filter of cylindrical drum surface.Structurally it comprises a horizontal rotary drum, and drum face upper berth constitutes filtering surface with filter screen.Space under the filtering surface is divided into some fan-shaped filter chambers that separate.Each filter chamber communicates with distributing valve.Rotary drum whenever rotates a circle, and each filter chamber is connected vacuum system and compressed air system in turn by distributing valve, and order is finished operations such as filtration, washing, extruding, discharging and filter screen regeneration.In the production, the filter chamber that is submerged in the mother liquor tank is communicated with vacuum system, and filtrate is sucked out filter, and solid particle then is attracted to and forms the alkali cake on the filtering surface; And after filter chamber leaves mother liquor with drum rotating, need to wash the alkali cake by the washing equipment across rotary drum, displace part salt in the alkali cake with wash water, thereby improve the quality of institute's output soda ash.Use in the vacuum-type drum filter at existing system alkali, its washing equipment be many groups parallel to each other along axially extended wash water groove of rotary drum and diversion plate, wash water is sprinkled upon on the alkali cake with the water curtain shape through wash water groove, diversion plate, such water curtain is inhomogeneous in the lip-deep flow distribution of alkali cake, cause that the local salt of alkali cake changes greatly, can cause adverse influence to the stability of product; Current are concentrated, and wash water flows down time of staying weak point when passing the alkali cake, causes the bigger defective of wash water consumption, and the wash water utilization rate is low.
The utility model content
Technical problem to be solved in the utility model provides a kind of system alkali vacuum-type drum filter washing equipment, and this device wash water utilization rate height can reduce the wash water consumption significantly, and help the stable of quality of soda ash.
The technical scheme that its technical problem that solves the utility model adopts is: system alkali vacuum-type drum filter washing equipment of the present utility model, this washing equipment fixedly is suspended at rotary drum washing station top, it is characterized in that: it comprises along the axially extended person in charge of rotary drum, this person in charge has at least one water inlet that is connected with the wash water carrier pipe, is responsible for its axis of upper edge and is arranged at intervals with several and is responsible for the shower nozzle that communicates.
On the basis of technique scheme, for making the alkali cake obtain all even sufficient washing, the suspended position of being responsible for is up-down adjustment easily, so that the atomization flow that adjacent two shower nozzles are produced has certain overlapping scope on alkali cake surface, the described person in charge's two ends are fixed on two gripper shoes by the slip fixture respectively, and these two gripper shoes slip respectively are fixed on the rotary drum machine frame at two sides.
As further improvement in the technical proposal, be responsible for for ease of clean and maintenance, to stop up to avoid shower nozzle, the described person in charge's two-port is provided with openable end cap.
The beneficial effects of the utility model are, adopt the shower nozzle of low-pressure, low discharge, make wash water produce uniform atomization flow on alkali cake surface, strengthened the penetration power of wash water, reduced the impulsive force of wash water to the alkali cake, wash water does not form channel, and its consumption is reduced significantly, and helps the stable of quality of soda ash.
Description of drawings
This specification comprises following two width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model system alkali with the vacuum-type drum filter washing equipment;
Fig. 2 is the left diagrammatic sketch of the utility model system alkali with the vacuum-type drum filter washing equipment.
Parts, position and numbering among the figure: gripper shoe 1, regulating tank 2, clip 3, the person in charge 10, water inlet 11, shower nozzle 12, end cap 13.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, system alkali vacuum-type drum filter washing equipment of the present utility model, this washing equipment fixedly is suspended at rotary drum washing station top, it comprises along the axially extended person in charge 10 of rotary drum, this person in charge 10 has at least one water inlet 11 that is connected with the wash water carrier pipe, is responsible for its axis of 10 upper edges and is arranged at intervals with several and is responsible for 10 shower nozzles that communicate 12.Washing equipment of the present utility model replaces traditional wash water groove and diversion plate with shower nozzle 12, shower nozzle 12 is with low-pressure, low discharge operation, make wash water produce uniform atomization flow on alkali cake surface, strengthened the penetration power of wash water, reduced the impulsive force of wash water to the alkali cake, wash water does not form channel, and its consumption is reduced significantly, and helps the stable of quality of soda ash.
Be responsible for 10 be provided with can adopt fixed or adjustable.For making the alkali cake obtain all even sufficient washing, the person in charge 10 suspended position should be able to be regulated easily, so that the atomization flow that adjacent two shower nozzles 12 are produced has certain overlapping scope on heavy alkali surface, the person in charge 10 two ends are fixed on two gripper shoes 1 by the slip fixture respectively, and these two gripper shoes 1 slip respectively are fixed on the rotary drum machine frame at two sides.Described slip fixture can be taked multiple version, Fig. 2 is disclosed wherein a kind of.As shown in Figure 2, described slip fixture comprise be opened on the gripper shoe 1 be responsible for 10 axial vertical regulating tanks 2, with and two ends pass regulating tank 2 and realize the clip 3 that is connected by screw thread pair and gripper shoe 1, will be responsible for 10 by clip 3 and be fixed on the gripper shoe 1.Two gripper shoes 1 can circumferentially be done slippage along rotary drum respectively and regulate.
