Description

TECHNICAL FIELD

[0001] The present application relates to the field of diatomite filter, in particular to a diatomite filter. BACKGROUND

[0002] The diatomite filter refers to a coated filter taking diatomite as the main medium and taking diatomite coating as the filter layer, mainly using mechanical screening to treat water containing micro-suspended matter, using the fineness and porosity of diatomite particles to remove suspended particles, colloids and other impurities in swimming pool water.

[0003] However, the traditional filter element is fixed and installed by a plurality of bolts, and the filter holes on the filter element are easy to be blocked, resulting in poor filtering effect. CONTENT OF THE UTILITY MODEL

[0004] The content part of the present application is used to introduce the concept in a simple form, which will be described in detail in the specific embodiment part. The content part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] In order to solve the technical problems mentioned in the background part, some embodiments of the present application provide a diatomite filter, comprising:

[0006] The shell has a water inlet pipe and a water outlet pipe, and a feeding pipe;

[0007] The inner shell is arranged in the outer shell, one end of the water outlet pipe extends into the inner shell and is connected with the inner shell, and one end of the inner shell has an opening;

[0008] The filter element is arranged at the opening of the inner shell;

[0009] The first connecting ring is movably arranged in the outer shell;

[0010] The first elastic member is arranged between the connecting ring and the outer shell;

[0011] The buffer assembly is arranged between the inner shell and the first connecting ring;

[0012] A long groove is formed on the outer wall of the outer shell for the water outlet pipe to move up and down.

[0013] Diatomaceous earth is introduced into the shell through the feed pipe, and then the diatomaceous earth forms a filter cake layer on the surface of the filter element. The liquid is filtered through the filter cake layer, and the filtered liquid enters the inner shell through the filter element and flows out from the water outlet pipe. Since the water inlet pipe is arranged at the upper end of the filter element, the liquid will have a certain impact force on the filter element and the inner shell, causing the inner shell to move downward under the action of the buffer assembly and the first elastic member, thereby avoiding the filter holes on the filter element being blocked. At the same time, when transporting the filter, the buffer assembly and the first elastic member can also play a certain buffering role, thereby preventing damage to the equipment.

[0014] Further, a first limiting groove is formed in the inner wall of the shell, and one end of the first connecting ring extends into the first limiting groove.

[0015] Further, the buffer assembly comprises:

[0016] A sleeve is fixedly arranged on the first connecting ring.

[0017] A sleeve rod is fixedly arranged on the bottom of the inner shell.

[0018] A second elastic member is sleeved on the sleeve rod, one end of which is connected to the inner wall of the sleeve, and the other end is connected to the bottom of the inner shell.

[0019] Further, a second connecting ring is arranged at the upper end of the inner shell, and a through hole is formed in the second connecting ring for mounting the filter element.

[0020] Further, a second limiting groove is formed in the inner wall of the shell, and a limiting ring is arranged on the second connecting ring and embedded in the second limiting groove.

[0021] Further, the end face of one end of the second connecting ring is configured as a first inclined surface.

[0022] Further, a valve is arranged on the water outlet pipe.

[0023] Further, the diatomaceous earth filter further comprises:

[0024] A motor;

[0025] A rotating shaft is connected to the output end of the motor at one end and extends into the inner shell at the other end.

[0026] A connecting rod is fixedly arranged on the rotating shaft.

[0027] Brushes are arranged on the connecting rod.

[0028] Further, the end face of one end of the connecting ring is configured as a second inclined surface.

[0029] Further, the diatomaceous earth filter further comprises:

[0030] A cylinder is fixedly arranged on the top of the shell.

[0031] The connecting plate is fixedly mounted on the piston rod of the cylinder;

[0032] The guide rod is fixed at one end to the top of the outer casing and the other end passes through the connecting plate;

[0033] The motor is mounted on the connecting plate.

[0034] The beneficial effect of this application is that it provides a diatomaceous earth filter with a filter element having an elastic structure. Attached Figure Description
