Technical Field

The invention belongs to the technical field of filter cloth cleaning, and particularly relates to a device for cleaning residual filter cakes of filter cloth.

Background

The filter cloth can be used for solid-liquid separation of materials, after solid-liquid separation and discharging, the filter cloth is generally washed by high-pressure water, so that fine particles in the filter cloth can be removed, the air permeability of the filter cloth is regenerated, and the filter cloth enters the next cycle.

Due to different characteristics and working conditions of materials, part of the materials seriously block the filter cloth, the air permeability of the filter cloth is poor, the operation performance of equipment is reduced, and the whole filter cloth is failed collectively under severe conditions. Such as: the temperature is reduced too fast, and the filtrate forms crystals on the surface of the filter cloth; the chemical property of the filter cake in the air changes for a long time, and new materials which are not easy to remove are formed on the surface of the filter cloth.

Disclosure of Invention

In view of the above, the present invention is expected to provide a device for cleaning a residual filter cake on a filter cloth, in which a plurality of symmetrical V-shaped creasing mechanisms, a cleaning brush and a high pressure nozzle are arranged, when the filter cloth advances along a length direction, a plurality of groups of approximately continuous creasing textures are generated on the surface of the filter cloth, the filter cloth does not deviate, a residual filter cake layer on the filter cloth is crushed and pulverized, under the action of the brush, the pulverized residual filter cake is mostly discharged out of the filter cloth, and then the high pressure nozzle performs high pressure water washing on the surface of the filter cloth, so that the residual filter cake is timely discharged out of the filter cloth, and the effect of deeply cleaning the filter cloth is achieved, thereby solving the problem that the filter cloth is seriously blocked by materials and is difficult to clean, and regenerating the air permeability of the filter cloth.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

the utility model provides a high pressure nozzle that is used for filter cloth to remain filter cake cleaning device, includes the frame, cleans the brush, connects the water pump, still be equipped with a plurality of pincher trees mechanisms of symmetry V-arrangement among the cleaning device, pincher trees mechanism is including upper corrugated roller, lower floor's pincher trees roller that has elastic support, upper corrugated roller with surface contact's on the filter cloth surface sets up to the convex surface, lower floor's pincher trees roller with surface contact's under the filter cloth surface sets up to the concave surface, pincher trees mechanism, clean brush, high pressure nozzle and all install in the frame.

Furthermore, the cleaning brushes are spiral and arranged in a row and are in contact with the lower surface of the filter cloth.

Further, the high pressure nozzle sets up to two rows, one row set up with upper strata pincher trees roller is same side, another row set up with lower floor pincher trees roller is same side.

The invention has the following beneficial effects: according to the device, the symmetrical V-shaped multiple creasing mechanisms, the cleaning brushes and the high-pressure nozzles are arranged, so that multiple groups of approximately continuous creasing textures are generated on the surface of the filter cloth when the filter cloth advances along the length direction, the filter cloth cannot deviate, residual filter cake layers on the filter cloth can be crushed and pulverized, under the action of the brushes, the pulverized residual filter cakes can be discharged out of the filter cloth in a vast number, and then the high-pressure nozzles are used for washing the surface of the filter cloth with high pressure water, so that the residual filter cakes can be timely discharged out of the filter cloth, the effect of deeply cleaning the filter cloth is achieved, the problem that the filter cloth is seriously blocked by materials and is difficult to clean is solved, and the air permeability of the filter cloth is regenerated.

Detailed Description

So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Fig. 1 is a schematic top view of a device for cleaning filter cloth residual filter cakes according to an embodiment of the present invention, and fig. 2 is a schematic front view of the device for cleaning filter cloth residual filter cakes according to the embodiment of the present invention, and as shown in fig. 1 and fig. 2, the device comprises a frame 6, a cleaning brush 2, and a high-pressure nozzle 3 connected to a water pump, wherein a plurality of symmetrical V-shaped creasing mechanisms 1 are further disposed in the device, each creasing mechanism 1 comprises an upper creasing roller 12 and a lower creasing roller 13, each creasing roller 12 is provided with an elastic support 11, the surface of the upper creasing roller 12 contacting with the upper surface of the filter cloth 4 is a convex surface, the surface of the lower creasing roller 13 contacting with the lower surface of the filter cloth 4 is a concave surface, and the creasing mechanisms 1, the cleaning brush 2, and the high-pressure nozzle 3 are all mounted in the.

Here, it is preferable that the cleaning brushes 2 are spiral-shaped and arranged in a row in contact with the lower surface of the filter cloth 4.

Here, it is preferable that the high pressure nozzles 3 are provided in two rows, one row being provided on the same side as the upper layer crumpling roller 12, and the other row being provided on the same side as the lower layer crumpling roller 13.

The device is provided with a plurality of symmetrical V-shaped creasing mechanisms, when the filter cloth advances along the length direction, a plurality of groups of approximately continuous creasing textures are generated on the surface of the filter cloth, acting forces generated when the filter cloth is creased can be mutually offset, the filter cloth can not be deviated, and residual filter cake layers on the filter cloth can be crushed and pulverized; the cleaning brush arranged in the device can discharge the pulverized residual filter cakes 5 to the outside of the filter cloth in a vast number, thereby avoiding the phenomena of local accumulation and blockage caused by excessive stripping of the filter cakes; and then the high-pressure nozzle arranged in the device washes the surface of the filter cloth with high-pressure water, and the residual filter cake can be discharged out of the filter cloth in time to achieve the effect of deeply cleaning the filter cloth.

Here, the filter cloth is driven to move forwards under the rotation of the roller; the sweeping brush is driven by a motor, and the current market is provided with the sweeper with the motor-driven brush, and the scheme can adopt an electric sweeper with the model of XF-3 in Xinfeng; conventionally, the high pressure nozzle leads to pipe to be connected with the water pump, and the sparge water can evenly distributed on the filter cloth surface when passing through the nozzle, accomplishes the comprehensive washing to the filter cloth.

The creasing mechanism 1, the cleaning brush 2 and the high-pressure nozzle 3 are fixedly arranged in a frame 6 of the device through bolts and nuts; one end of the cleaning brush 2 in fig. 2 is provided through the bearing housing 7.
