Description
Technical Field
The utility model relates to the technical field of filters, in particular to a filtering device of a precision rotary drum filter.
Background
Because the environmental pollution problem is serious and the water resource is limited, the limited water resource has to be recycled. When the water resource is recycled, certain optimization treatment needs to be carried out on the water body in order to enable the water body to meet the water quality requirement for reuse. The current popular method is to adopt a rotary drum filter for removing suspended matters to carry out water treatment, in the using process, a high-pressure washing pump is needed to be used to clean the filter screen through a spray head, when the filter screen is washed, if the water pressure is too high, the filter screen can be damaged, the service life of the filter screen is shortened, and if the water pressure is too low, the washing effect is poor.

In order to overcome the defects of the prior art, the utility model provides the filtering device of the precision drum filter, which has the advantages of reasonable structure, reliable filtering, large filtering area and long service life.
The utility model is realized by adopting the following technical scheme: a filter device of a precise drum filter comprises a shell, a drum body driven by a motor is arranged in the shell, a filter screen is arranged outside the rotary drum body, a water inlet, a water outlet and a slag discharge port are also arranged on the shell, the top of the shell is provided with a cleaning mechanism for washing the filter screens, the filter screens are detachably arranged on the outer wall of the rotary drum body, the radial section of the filter screen is arc-shaped, the filter screen comprises a pair of concentric mounting plates which are arranged at intervals, a plurality of through holes are arranged on the mounting plates, two filter screen bodies are arranged between a pair of the mounting plates, the two filter screens are respectively and correspondingly attached to the two mounting plates, a gap is formed between the two filter screen bodies, a plurality of air bags are arranged in the gap at intervals, and the outer walls of the air bags and the filter screen body are fixedly arranged.
A plurality of perforation on two mounting panels correspond the setting, the gasbag is located between two on same radial perforation.
And the outer wall of the shell is also provided with a control cabinet for controlling the motor, the cleaning mechanism and the water inlet rate and the water outlet rate.
The water inlet extends to the interior of the rotary drum body.
Compared with the prior art, in the utility model, in the rotating process of the drum body, the air bag can contract when entering water and recover when yielding water, namely, the air bag generates micro deformation to push and pull the two filter screen bodies, so that waste residues on the filter screen bodies can fall off conveniently.

FIG. 1 is a first schematic structural diagram of the present invention;
FIG. 2 is a second schematic structural view of the present invention;
FIG. 3 is a schematic view of a screen construction;
in the figure: 1. a housing; 2. an electric motor; 3. a drum body; 4. a water inlet; 5. a water outlet; 6. a slag discharge port; 7. a cleaning mechanism; 81. mounting a plate; 82. perforating; 83. a filter screen body; 84. an air bag; 9. a control cabinet.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1-3, a filter device of a precise drum filter comprises a casing 1, a drum body 3 driven by a motor 2 is arranged in the casing 1, a filter screen is arranged outside the drum body 3, the casing 1 is further provided with a water inlet 4, a water outlet 5 and a slag discharge port 6, a cleaning mechanism 7 for washing the filter screen is arranged at the top of the casing 1, the filter screens are detachably arranged on the outer wall of the drum body 3, the radial cross section of the filter screen is arc-shaped, the filter screen comprises a pair of concentric and spaced mounting plates 81, the mounting plates 81 are provided with a plurality of through holes 82, two filter screen bodies 83 are arranged between the mounting plates 81, the two filter screens are respectively and correspondingly attached to the two mounting plates 81, a gap is formed between the two filter screen bodies 83, and a plurality of air bags 84 are arranged in the gap at intervals, the outer wall of the air bag 84 is fixedly arranged with the filter screen body 83. A plurality of arc-shaped filter screens wrap the outer wall of the rotary drum body 3 to form a cylindrical whole; in the operation process, the rotary drum body 3 is partially positioned above the liquid level in the shell 1 and partially positioned below the liquid level in the shell 1, so that, during the rotation of the drum, the same air bag 84 will enter below the liquid level and return to above the liquid level and then enter below the liquid level in a reciprocating manner, because the air bag 84 can contract under the liquid level and under the hydraulic pressure, when the air bag 84 is positioned above the liquid level, the air bag 84 recovers, and through the micro deformation generated by the air bag 84, under the action of pushing and pulling the two filter screen bodies 83, waste residues on the filter screen bodies 83 can fall off conveniently, so that, under the condition of the same cleaning effect, the flushing pressure of the cleaning mechanism 7 can be reduced, the filter screen body 83 is protected, the filter screen body 83 is prevented from being damaged, the structure is reasonable, the filtering is reliable, the service life is long, the cleaning effect of the filter screen body 83 is improved, and the filtering area is also increased.
The through holes 82 of the two mounting plates 81 are correspondingly arranged, and the air bag 84 is arranged between the two through holes 82 in the same radial direction. Thus, the screen body 83 can be pulled to the maximum extent by the contraction and restoration of the air bag 84, the pushing and pulling action of the air bag 84 can assist the washing mechanism 7, and the washing of the screen body 83 can be completed more efficiently.
And the outer wall of the shell 1 is also provided with a control cabinet 9 for controlling the motor 2, the cleaning mechanism 7 and the water inlet rate and the water outlet rate. The controller is arranged in the control cabinet 9, and the opening and closing of the motor 2 and the cleaning mechanism 7 and the water inlet speed and the water outlet speed can be reliably controlled through the controller, so that the sustainable proceeding of the filtering effect is ensured.
The water inlet 4 extends to the inside of the drum body 3. Therefore, after the sewage enters the rotary drum body 3, in the process of penetrating out of the rotary drum body 3, the waste residues in the sewage can be reliably intercepted.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
