Description

Technical Field

[0001] The utility model belongs to the technical field of candle filters, and more specifically, relates to a self-cleaning candle filter. Background Art

[0002] The candle filter, named for its candle-like filter element, is a highly efficient solid-liquid separation device. It utilizes pressure filtration technology to achieve solid-liquid separation. It features high efficiency and energy saving, airtightness and precision, easy maintenance, safety, reliability, and a high degree of automation. During the filtration process, the slurry is pumped into the cylinder and forced through the filter medium outside the element. Solid particles are trapped on the surface of the filter cloth, forming a filter cake, while the clear liquid passes through the cloth into the filter element and is discharged. When the filter cake reaches a certain thickness, the filter automatically backflushs and removes the residue, ensuring continuous filtration.

[0003] Based on the above, the inventors found the following problems: the current candle filter needs to clean the filter element after backblowing and removing slag, but the existing method is mostly to remove the filter element for cleaning, and then install it after cleaning, which has a poor cleaning effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-cleaning candle filter is provided to achieve the purpose of having more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a self-cleaning candle filter to solve the problem that the existing candle filter has low cleaning efficiency for the filter element when in use.

[0006] The purpose and function of the self-cleaning candle filter of the utility model are achieved by the following specific technical means:

[0007] A self-cleaning candle filter comprises a candle filter body, a filter element is installed in the candle filter body, a liquid inlet and a liquid discharge port are installed on the surface of the shell of the candle filter body, a slag discharge port is installed at the bottom of the candle filter body, a mounting plate is installed on the surface of the candle filter body, an air pump is installed on the surface of the mounting plate, a connecting pipe is installed at the output end of the air pump, one end of the connecting pipe extends to the candle filter body and an annular pipe is installed therein, a plurality of branch pipes are installed on the surface of the annular pipe, a plurality of aeration holes are opened on the surface of the branch pipes, and an exhaust port is installed at the top of the candle filter body.

[0008] Furthermore, the branch pipes and the annular pipe are connected via a detachable mechanism.

[0009] Furthermore, the detachable mechanism is a threaded connector installed on the surface of the branch pipe and a threaded hole opened on the surface of the annular pipe, and the threaded connector and the threaded hole match.

[0010] Furthermore, a plurality of supporting legs are installed at the bottom of the candle filter body.

[0011] Furthermore, an observation window is provided on the surface of the candle filter body.

[0012] Furthermore, the observation window is made of tempered glass.

[0013] Furthermore, the surface of the candle filter body is coated with an anti-rust coating.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model cooperates with the mounting plate, the air pump, the connecting pipe, the annular pipe, the branch pipe, the aeration hole and the exhaust port. When the filter cake on the filter element in the candle filter body reaches saturation, the slag discharge port is opened and the back-flushing function of the candle filter body is started to shake the filter cake off the filter element and discharge it from the slag discharge port. Then the slag discharge port is closed and water is injected through the exhaust port. When the water covers the filter element, the air pump is started. When the air pump is started, the gas generated by the air pump will enter the annular pipe through the connecting pipe, then enter the branch pipe through the annular pipe, and be ejected from the aeration hole. The ejected gas will cause the water to roll, and the rolling water will clean the filter element. When the cleaning is completed, the slag discharge port is opened and the water can be discharged. Through the above design, the filter element can be cleaned quickly, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
