Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a basket filter. Background Art

[0002] The basket filter is a filtering device used in water treatment. It has a simple structure and is flexible to use. It is widely used in industrial production. The basket filter is widely used in industrial pipelines such as chemical industry and light industry. At present, the basket filter on the market includes a main cylinder and a liquid inlet pipe and a liquid outlet pipe respectively arranged on both sides of the filter cylinder. The main cylinder is provided with a filter cylinder, and the main cylinder is provided with an opening for taking out the filter cylinder. The opening is provided with an end cover. When the liquid flows through the filter cylinder, the impurity particles are filtered by the filter cylinder inside the filter cylinder. The filtered liquid flows through the liquid outlet pipe and flows out of the basket filter, which plays the role of filtering impurities. In the traditional basket filter, the filter cylinder is set to the same circle as the main cylinder, and the gap between the filter cylinder and the main cylinder is small. When there are impurities in the liquid, under the action of the liquid flow direction, the impurities are mostly alluvial on the filter cylinder wall close to the liquid outlet pipe. On the side of the filter cylinder and the liquid outlet pipe, the liquid enters the liquid outlet pipe from the filter cylinder with a larger area, and the pipe diameter becomes narrower, so that the water pressure at the liquid outlet pipe is large, which is easy to be blocked, resulting in poor drainage.

[0015] The following will be combined with the accompanying drawings of the structural schematic diagram of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] As shown in Figure (1), a basket filter comprises a liquid inlet pipe 1, a main cylinder 2, a filter cartridge 3, a concave net 31, an end cap 5 and a liquid outlet pipe 6. The liquid to be filtered enters the basket filter through the liquid inlet pipe 1. The main cylinder 2 is cylindrical. The upper opening of the main cylinder 2 is provided with an end cap 5. The liquid inlet pipe 1 is connected to one side of the main cylinder 2 through a flange. The liquid outlet pipe 6 is provided on the other side of the main cylinder 2. The liquid to be filtered passes through the basket filter, which can effectively filter out impurities and particles suspended in the liquid. A fixing frame 21 is provided on the inner wall of the main cylinder 2. A side ring 32 is provided on the upper edge of the filter cartridge 3. The side ring 32 is mounted on the main fixing frame 21, which can filter The cylinder 3 is mounted in the main cylinder body 2, and impurities in the liquid are filtered and deposited in the filter cylinder 3 through the filter cylinder 3. The height of the filter cylinder 3 on the side of the liquid inlet pipe 1 is lower than the liquid inlet pipe 1, so that unfiltered liquid enters the filter cylinder 3 for filtration, and the height of the filter cylinder 3 on the side of the liquid outlet pipe 6 is higher than the liquid outlet pipe 6, so that the body fluid filtered by the filter cylinder 3 is discharged through the liquid outlet pipe 6. A concave net 31 is fixedly connected to the side of the filter cylinder 3 close to the liquid outlet pipe 6. The concave net 31 is a semi-arc structure, and the concave net 31 is concave toward the filter cylinder 3. On the one hand, the setting of the concave net 31 increases the drainage area of ​​the filter cylinder 3 close to the liquid outlet pipe. On the other hand, it also increases the gap between the filter cylinder 3 and the liquid outlet pipe 6 to prevent impurities from clogging the liquid outlet pipe 6.

[0017] The filter cartridge 3 is provided with a handle 4, which is used to easily lift the filter cartridge 3 out of the main cylinder 2 and dump out the impurities accumulated in the filter cartridge 3. The filter cartridge 3 is made of stainless steel, and the concave net 31 is made of stainless steel.

[0018] The specific workflow is as follows:

[0019] The liquid with impurities enters the basket filter through the liquid inlet pipe 1, and the unfiltered liquid enters the filter cartridge 3. The impurities are filtered and deposited in the filter cartridge 3. The filtered liquid passes through the concave net 31 under pressure and flows into the liquid outlet pipe 6, completing the entire filtering process.

[0020] According to the above process, the problem that the gap between the filter cartridge and the main cylinder is too small and the outlet pipe is easily blocked due to the small drainage area caused by the filter cartridge bulging toward the outlet pipe can be avoided.

[0021] To sum up, the basket filter has a simple structure. By setting the filter cartridge and the position on the side close to the liquid outlet pipe to be a concave net concave into the filter cartridge, the drainage area of ​​the filter cartridge and the liquid outlet pipe is increased, thereby preventing the liquid outlet pipe from being easily blocked due to the small drainage area caused by the filter cartridge bulging toward the liquid outlet pipe.

[0022] It should be noted that the above is only a preferred embodiment of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments. Without departing from the spirit or basic features of the utility model, the utility model can be implemented in other specific forms. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
