Description

Disassembly-free online self-cleaning basket filter

The technical field is as follows:

the utility model belongs to the technical field of fluid impurity filters, specifically be an it can online self-cleaning type basket filter to exempt from to dismantle.

Background art:

the basket filter is arranged on a gas or liquid pipeline and has the function of filtering and intercepting solid impurity particles such as welding slag, rust, silt, dust and the like carried by various fluids, so that the blockage and damage of the pipeline, the pump, the valve, equipment and the like are avoided, the normal work of the equipment is protected, and the safety production is guaranteed.

The basket filter consists of mainly connecting pipe, cylinder, filtering basket, flange cover, fastener, etc. The two ends of the cylinder body of the filter are provided with a fluid inlet and a fluid outlet, and the filter basket is arranged between the inlet and the outlet and is used for filtering impurities in the fluid. The top cover is arranged on the upper part of the cylinder body and is fixed on the cylinder body in a sealing way through a circle of bolt and a rubber gasket. After the fluid enters the filter basket through the main pipe, solid impurity particles are intercepted in the filter basket, and clean fluid passes through the filter basket and is discharged from the outlet of the filter. When piling up more solid particulate matter in the filter basket, can cause the circulation rate of fluid to descend to filter entrance and exit pressure difference can increase, influences the normal efficiency of follow-up equipment, needs take apart the filter this moment and washs.

The existing basket filter has the advantages that in order to avoid impurity accumulation to cause filter blockage and influence filtering efficiency, a flange bolt of an upper top cover of the filter needs to be periodically detached, the upper top cover is opened, a filter basket is taken out from the upper portion to be cleaned, the filter basket is installed again after being cleaned, and the filter basket is installed and fixed. The upper top cover of the existing basket filter is complex to disassemble and assemble, and when the operations are carried out, equipment needs to be shut down and stop water, the filter is emptied, and much time is wasted. In actual use, a plurality of large filters are used, the pressure grade is higher, and the filter is very time-consuming and labor-consuming to disassemble, clean and reassemble, so that the cost is increased. Meanwhile, the connection part of the filter parts is also possibly abraded in the process of dismounting and mounting, so that the risk of leakage at the joint of the basket filter is possibly caused, and certain potential safety hazards exist.

The invention content is as follows:

the utility model aims to solve the above-mentioned basket filter and dismantle and wash inconvenient, need the system shut down, the process is wasted time and energy, the problem of leaking appears easily, but provides a dismantle-free online self-cleaning type basket filter.

In order to solve the above problem, the utility model provides a technical scheme does:

the utility model provides an exempt from to dismantle online self-cleaning type basket filter, includes the barrel and strains the basket, the barrel both sides are equipped with import and export, barrel top respectively and are equipped with the flange top cap, and the barrel bottom is equipped with from the blow off pipe of taking the blowoff valve, its characterized in that: the filter basket is a tapered cylindrical filter screen which penetrates through the upper part to the lower part of the cylinder body, and the lower end of the filter basket is open; the top end of the filter basket is an inclined section, one end of the filter basket is abutted to the horizontal section of the lower end of the inlet, and the other end of the filter basket is abutted to the horizontal section of the upper end of the outlet and is flush with the flange top cover; the bottom of the filter basket is hermetically connected with the cylinder body, and the lower end of the filter basket is communicated with a drain pipe at the bottom of the cylinder body. The fluid flows into the cylindrical filter basket from the inlet of the filter for filtering, the clean fluid flows out from the outlet, impurities in the fluid are intercepted by the tapered cylindrical filter screen and accumulated at the bottom of the filter basket, when the fluid needs to be cleaned, the drain valve on the drain pipe is directly opened, and the impurities accumulated at the bottom of the filter basket can be discharged from the drain outlet along with the fluid. The tapered cylindrical filter basket is easy to accumulate dirt, the sectional area of the filter basket is reduced, the flushing force can be increased, and flushing and sewage discharging are facilitated.

The blowdown valve is an electric valve or a pneumatic valve, can be remotely operated to blowdown, and is suitable for occasions where workers are not easy to approach.

An exempt from to dismantle online self-cleaning type basket filter, only need with fluid inlet and export keep unobstructed, blowoff valve on the normal close blow off pipe just can normal operating. If the impurity in the filtering fluid is more, when the filter needs to be cleaned, the blowoff valve on the blowoff pipe can be opened when the fluid inlet and outlet and the blowoff valve are not closed, and the filter basket is regularly washed on line, so that the system halt can be avoided, the continuous production is ensured, and the defects of time and labor waste and the like of the filter disassembly can also be avoided.

Adopt the utility model provides a technique, than prior art, has following beneficial effect:

(1) basket filter can online cleaning, the blowdown is convenient, does not need the system shutdown, exempts from to dismantle, has saved and has overhauld abluent time, has reduced the cost of overhaul.

(2) The frequency of equipment disassembly is reduced, equipment abrasion caused by frequent equipment disassembly is avoided, the possibility of fluid leakage is reduced, and the system safety guarantee is better.

(3) Simple structure, convenient to use, basket filter overall dimension can keep unanimous with conventional basket filter overall dimension, guarantee with the interchangeability of original filter, the old system's of being convenient for transformation sparingly reforms transform the expense.

(4) The bottom blowoff valve is an electric valve or a pneumatic valve, can carry out remote operation for blowdown, and is suitable for occasions where workers are not easy to approach.
