Description
Technical Field
The utility model relates to the technical field of basket filters, in particular to a basket filter capable of directly discharging sewage.
Background
The basket filter can remove a small amount of solid particles in the liquid, so that the normal operation of main equipment is protected. The basket filter mainly comprises a connecting pipe, a main pipe, a filter cylinder, a filter basket, a flange cover, a fastener and the like. After the liquid enters the filter basket through the main pipe, the solid impurity particles are blocked in the filter basket, and clean fluid is discharged from the filter outlet through the filter basket. When the main pipe is required to be cleaned, the screw plug at the bottom of the main pipe is unscrewed, fluid is discharged, the flange cover is disassembled, and the main pipe is reloaded after cleaning, for example, the basket filter disclosed in the publication No. CN206372573U can be opened to clean the filter basket after the liquid in the basket filter is discharged.
However, in normal use, the production system needs to run continuously, the liquid delivery to clean the filter device is stopped, and the maximum speed is more than 30 minutes from the time of removing the bolts to the time of being cleaned and finally being reused. The system runs for a long time in a broken material, which can cause production abnormality and serious safety accidents.
It is common practice to design two filter systems, one on top of the other, simultaneously with the design. When one is blocked, the filter is switched to another set of filter for use, and the blocked filter is cleaned. However, there are two disadvantages to doing so, one is that the installation cost is increased; secondly, in a narrow area, when the filter is large, the installation position is not too wide, and the maintenance space for cleaning the filter is required to be left.
Disclosure of Invention
In order to solve the technical problems, the utility model provides the basket filter for directly discharging sewage, which changes the cleaning mode of impurities in the filter screen of the original basket filter, so that the basket filter can quickly perform cleaning operation in the use process and recover the original functions of the filter.
In order to achieve the technical purpose, the utility model adopts the following scheme: the basket filter for directly discharging sewage comprises a filter cylinder, a filter basket and a sewage discharging valve, wherein the filter basket is arranged in the filter cylinder; the filter basket is characterized by further comprising a filter basket baffle ring, wherein a through hole is formed in the bottom surface of the filter cylinder, the filter basket baffle ring is fixed on the bottom surface of the filter cylinder at the inner side of the through hole, the lower end of the filter basket is of an open structure, and the filter basket baffle ring is sleeved in the lower port of the filter basket; a drain valve is arranged at the through hole at the bottom of the filter cylinder.
Compared with the prior art, the utility model has the beneficial effects that: the utility model solves the problem of redundant design caused by cleaning the filter basket and the filter cartridge in the use process of the traditional basket type filter; and the temporary material stopping of the system, which is possibly caused by switching the filter or unfinished cleaning, is avoided in the cleaning process. The direct-connection blow-down valve is additionally arranged at the bottom of the filter cylinder, so that blow-down operation is facilitated, cleaning operation steps are simplified, and overhaul workload is greatly reduced.
The preferable scheme of the utility model is as follows:
the blow-down valve is provided with a valve spanner for controlling the on-off state of the blow-down valve.
The two ends of the filter cylinder are respectively provided with a water inlet pipe and a water outlet pipe, and the end parts of the water inlet pipe and the water outlet pipe are fixed with flanges.
The upper end of the filter cylinder is connected with a sealing flange cover through a bolt.
Drawings
FIG. 1 is a schematic diagram of a basket filter for direct blowdown according to an embodiment of the present utility model;
marked in the figure as: 1. a filter cartridge; 2. a connecting flange; 3. sealing the flange cover; 4. a bolt; 5. a filter basket; 6. a filter basket baffle ring; 7. a blow-down valve; 8. a fastener; 9. a valve spanner.
Detailed Description
The present utility model will be described in detail with reference to the following embodiments for a full understanding of the objects, features and effects of the present utility model, but the present utility model is not limited thereto.
As shown in figure 1, the basket filter for direct sewage discharge provided by the utility model consists of a filter cylinder 1, a filter basket 5, a filter basket baffle ring 6, a sewage discharge valve 7 and the like, wherein the left side and the right side of the filter cylinder 1 are respectively connected with a water inlet pipe and a water outlet pipe, and the end parts of the water inlet pipe and the water outlet pipe are fixedly provided with a connecting flange 2 which is used for connecting a liquid medium conveying pipeline so that the liquid medium conveyed by the pipeline flows through the filter cylinder 1. The upper end of the filter cartridge 1 is connected with a sealing flange cover 3 through a flange and bolts 4, the sealing flange cover 3 is used for checking or replacing the filter basket 5, and the sealing flange cover 3 is not required to be opened for cleaning the filter basket 5.
The filter basket 5 is arranged in the filter cartridge 1, and liquid flowing in from the inlet of the filter flows into the filter cartridge 1 and flows through the filter basket 5 to filter impurities in the liquid. The lower extreme of filtering basket 5 is open structure, and the through-hole that is used for the blowdown is seted up to the lower extreme of straining a 1, is fixed with on the inboard straining a 1 bottom plate of through-hole and strains basket baffle 6, and the open suit in lower extreme of filtering basket 5 is outside straining basket baffle 6, supports filtering basket 5 bottom by straining basket baffle 6 to prevent that filtering basket 5 from taking place to warp at fluid flushing in-process.
The bottom of the filter cartridge 1 is also connected with a drain valve 7 through a fastener 8 (such as a bolt and a nut), an opening of the drain valve 7 is opposite to the lower port of the filter basket 5, the drain valve 7 is opened, and sundries in the filter basket 5 are discharged through the drain valve 7. The blow-down valve 7 is provided with a valve spanner 9 for controlling the opening and closing states of the blow-down valve 7.
The using process comprises the following steps:
in use, the direct blowdown basket filter is connected to the fluid conduit in the same manner as a conventional basket filter. When the filter is normally used, the blow-down valve 7 at the bottom of the basket filter is closed, fluid in a pipeline enters the filter cylinder 1 through the connecting flange 2, flows out of the filter after being filtered by the filter basket 5, and achieves the purpose of filtering liquid. When more sundries exist in the filter basket 5 and the sundries in the filter need to be cleaned, a valve spanner 9 on the blow-down valve 7 is opened, and the blow-down valve 7 is controlled to open the flow. At this time, sundries in the filter basket 5 can flow through the blow-down valve 7 through the through hole at the bottom of the filter cartridge 1 and be discharged to a designated area, so that the purpose of cleaning the filter basket 5 is achieved.
The applicant has carried out field experiments on the equipment, and through actual measurement and calculation, the whole pollution discharge process does not exceed 5 seconds, and the equipment can be operated at any time without any adverse effect on the system equipment.
Finally, it should be noted that: the above list is only a preferred embodiment of the present utility model, and it is understood that those skilled in the art can make modifications and variations thereto, and it is intended that the present utility model be construed as the scope of the appended claims and their equivalents.
