AI Technical Summary
Existing horizontal security filters lack a dedicated drainage structure, which poses a safety risk when removing the end caps. Furthermore, the exhaust function is inadequate, making it easy for air blockages to form, affecting the filtration effect and filter life.
A horizontal security filter with built-in drainage and venting functions is designed. It drains accumulated water through a drain pipe and vents air through a venting mechanism, avoiding safety risks and air blockage, ensuring stable filtration effect and extended filter life.
It eliminates the safety risk of objects hitting the filter element during replacement and prevents air blockage through a comprehensive venting function, ensuring stable filtration performance and extending the filter element's lifespan.

Abstract
Claims
1. A horizontal security filter with self-draining exhaust, comprising a filter cylinder (1), two end covers (3) and a filter element (2), characterized in that: The lower side of the filter cylinder (1) is connected to two drain pipes (4), which are located on the left and right sides of the filter element (2) and are each equipped with a ball valve. Venting mechanisms are provided on the left and right sides of the filter element (2). Each venting mechanism includes a circular shell (5) connected to the upper side of the filter cylinder (1). A fixed plate (6) is fixedly connected inside the circular shell (5). Multiple first vent holes (7) are provided through the outer wall of the fixed plate (6). A venting mechanism is provided above the fixed plate (6). A lifting plate (9) is provided. A first sealing ring (10) is embedded in the lower end of the lifting plate (9) through a groove. A turntable (11) is rotatably connected to the upper end of the lifting plate (9) through an annular slide groove and an annular slide rail. A screw (12) is fixedly connected to the upper end of the turntable (11) through the circular shell (5) and threadedly connected to the circular shell (5). A handle is fixedly connected to the upper end of the screw (12). Multiple second exhaust holes (8) are evenly distributed along the axial direction through the outer wall of the circular shell (5). Each of the two end caps (3) has a number of circumferentially distributed limiting rods (16) fixedly connected to the opposite side, which are in contact with the filter element (2).
2. A horizontal security filter with integral drain and exhaust according to claim 1, characterized in that: The filter element (2) has a second sealing ring (14) embedded in the groove on both the left and right sides of its outer wall, which abuts against the inside of the filter cylinder (1).
3. The horizontal security filter with drain and exhaust according to claim 1, characterized in that: Both of the two end caps (3) have a sealing gasket (15) that abuts against the filter cylinder (1) installed on opposite sides by a groove.
4. The horizontal security filter with integral drain and exhaust according to claim 1, wherein: The outer walls of both end caps (3) are fixedly connected with a first connecting ring (17), and the left and right sides of the outer wall of the filter cylinder (1) are fixedly connected with a second connecting ring (18). The first connecting ring (17) on the left side and the second connecting ring (18) on the left side are fixedly connected by multiple bolts, and the first connecting ring (17) on the right side and the second connecting ring (18) on the right side are fixedly connected by multiple bolts.
5. The horizontal security filter with integral drain and exhaust according to claim 1, wherein: The upper end of the lifting plate (9) is fixedly connected to two slide rods (13) that penetrate the circular shell (5) and are slidably connected to the circular shell (5).
6. The horizontal security filter with integral drain and exhaust according to claim 1, wherein: The front side of the filter cylinder (1) is connected to the outlet pipe (19) located to the left of the filter element (2), and the front side of the filter cylinder (1) is connected to the inlet pipe (20) located to the right of the filter element (2).
