Description

Technical Field

[0001] The utility model relates to a laboratory, in particular to laboratory experimental equipment, specifically a filter with a self-cleaning function. Background Art

[0002] At present, laboratories generally use Y-type filters to supply water after filtration. The Y-type filter needs to be manually cleaned regularly. During manual cleaning, the water supply of the laboratory will be cut off, affecting the daily use of the laboratory.

[0003] Therefore, it is necessary to provide a filter with a self-cleaning function to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a filter with a self-cleaning function.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A filter with a self-cleaning function, comprising a water inlet and a water outlet arranged correspondingly, and a group of filter modules are arranged in parallel between the water inlet and the water outlet;

[0007] A differential pressure gauge is provided on the filter outlet of the filter module. The differential pressure gauge is used in conjunction with the controller. One filter module is used as the normal filter part and the other is used as the backup filter part. The differential pressure gauge of the normal filter part detects abnormal pressure and switches to the backup filter part. The controller controls the cleaning module of the normal filter part to clean it, forming an uninterrupted filtering and water supply, self-cleaning filtering water supply structure.

[0008] Furthermore, the filter module includes a main body, and a filter body is arranged in the main body.

[0009] Furthermore, a cleaning brush is arranged in the filter body, and the cleaning brush is driven by a motor.

[0010] Furthermore, the main body is also provided with an air flushing port, and the air flushing port is connected to the air compression equipment.

[0011] Furthermore, the filter module is provided with a sewage outlet.

[0012] Furthermore, the common filter section and the standby filter section are switched by means of a solenoid valve.

[0013] Furthermore, the filter body is a high-precision stainless steel filter element.

[0014] Furthermore, the cleaning brush is a stainless steel brush body.

[0015] Compared with the prior art, the utility model ensures 24-hour uninterrupted filtered water supply in the laboratory and ensures continuous use of the experiment through an uninterrupted filtered water supply and self-cleaning filtered water supply structure.

[0019] A differential pressure gauge 9 is provided on the filter outlet of the filter module. The differential pressure gauge 9 is used in conjunction with the controller 10. One filter module is used as a common filter part, and the other is used as a spare filter part. The differential pressure gauge 9 of the common filter part detects abnormal pressure and switches to the spare filter part, and the controller 10 controls the cleaning module of the common filter part to clean it, thereby forming an uninterrupted filtering and water supply, self-cleaning filtering water supply structure.

[0020] The filter module comprises a main body 1 , in which a filter body 3 is arranged.

[0021] A cleaning brush 4 is arranged in the filter body 3 and is driven by a motor.

[0022] The main body 1 is also provided with an air flushing port 8, and the air flushing port 8 is connected to the air compression equipment.

[0023] The filter module is correspondingly provided with a sewage outlet 7.

[0024] The normal filter section and the standby filter section are switched by the solenoid valve 11 .

[0025] The filter body 3 is a high-precision stainless steel filter element.

[0026] The cleaning brush is a 4-piece stainless steel brush body.

[0027] Compared with the prior art, the utility model ensures 24-hour uninterrupted filtered water supply in the laboratory and ensures continuous use of the experiment through an uninterrupted filtered water supply and self-cleaning filtered water supply structure.

[0028] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
