Description

Technical Field

[0001] This utility model specifically relates to a vertical filter. Background Technology

[0002] Vertical filters mainly come in two types: basket filters and bag filters. Basket filters are used on oil or other liquid pipelines to filter out impurities. The filter pore area is 2-3 times larger than the pipe diameter area, and the filter screen is shaped like a basket, hence the name basket filter. When using a basket filter, the cover needs to be opened periodically to remove and clean the filter screen. In current technology, the cover of a basket filter is usually fixed with multiple bolts, which makes disassembly and installation cumbersome, making it inconvenient to remove and clean the filter screen, thus reducing work efficiency. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a vertical filter.

[0004] A vertical filter includes a cylindrical body, a filter basket, and a sealing cover. The filter basket is disposed within the cylindrical body. The sealing cover is detachably connected to an opening on the upper part of the cylindrical body. The sealing cover includes a connecting cover and a pressure cover. The pressure cover is rotatably disposed on the upper side of the connecting cover and can move up and down relative to the connecting cover. A flange is provided at the upper end of the cylindrical body, and a positioning notch is recessed on the flange. A positioning protrusion is provided on the connecting cover corresponding to the positioning notch. A plurality of arc-shaped protrusions with gradually increasing size are provided at intervals along the circumference of the lower side of the flange. A plurality of connecting arms are provided at intervals along the circumference of the pressure cover. A horizontal shaft is provided on one side of the connecting arm and below the flange. The horizontal shaft abuts against the arc-shaped protrusions as the pressure cover rotates, so that the pressure cover is pressed tightly against the connecting cover downward. A limiting member is provided on the cylindrical body to drive the horizontal shaft to remain in contact with the arc-shaped protrusions.

[0005] In one embodiment, the limiting member includes a connecting seat located on one side of the cylinder, the upper side of the connecting seat has a recessed groove, a limiting rod is movably disposed in the groove, and a spring is disposed in the groove, with the spring abutting between the limiting rod and the bottom of the groove.

[0006] In one embodiment, the limiting member further includes a screw and a guide shaft arranged coaxially. The screw is rotatably disposed on one side of the cylinder. The connecting seat is respectively fitted onto the screw and the guide shaft, and the connecting seat is threadedly connected to the screw. A knob is provided at one end of the screw.

[0007] In one embodiment, a pin hole is provided on one side of the limiting rod and located in the groove, and a through hole is provided on one side of the connecting seat corresponding to the pin hole, and a pin is inserted between the through hole and the pin hole.

[0008] In one embodiment, the horizontal shaft is threadedly inserted into the connecting arm.

[0009] In one embodiment, a fixed shaft is provided at the center of the upper side of the connecting cover, and the pressure cover is movably sleeved on the fixed shaft so that the pressure cover can rotate around the fixed shaft and move axially along the fixed shaft.

[0010] In one embodiment, the width of the positioning notch is greater than the diameter of the horizontal axis.

[0011] In one embodiment, a sealing ring is provided between the connecting cover and the cylinder.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This utility model uses a combined structure of a sealing cap and a pressure cap. The connecting cap is used to seal and cover the opening on the cylinder body. The pressure cap rotates relative to the connecting cap, causing the horizontal shaft on the pressure cap and located below the flange to rotate as well. The horizontal shaft rotates and abuts against the arc-shaped protrusion, causing the pressure cap to move downward relative to the connecting cap and press tightly against the connecting cap as it rotates. With the help of a limiting component, the horizontal shaft is kept in contact with the arc-shaped protrusion, thus achieving a tight installation connection between the sealing cap and the cylinder body. When disassembling, simply release the limiting component and rotate the pressure cap to make the horizontal shaft disengage from the arc-shaped protrusion and rotate it to the positioning notch of the flange, thus achieving the disassembly and separation of the sealing cap and the cylinder body.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4The present invention preferably provides a vertical filter, including a cylindrical body 1, a filter basket, and a sealing cover. The filter basket is disposed inside the cylindrical body 1. The sealing cover is detachably connected to the opening on the cylindrical body 1. The sealing cover includes a connecting cover 3 and a pressure cover 4. The pressure cover 4 is rotatably disposed on the upper side of the connecting cover 3 and can move up and down relative to the connecting cover 3. The upper end of the cylindrical body 1 is provided with a flange 5, and the flange 5 has a recessed positioning notch 6. The connecting cover 3... The positioning notch 6 is provided with a positioning protrusion 7. The lower side of the flange 5 is provided with a number of arc-shaped protrusions 8 that gradually increase in size along the circumference. The pressure cover 4 is provided with a number of connecting arms 9 that are spaced apart along the circumference. A horizontal shaft 10 is provided on one side of the connecting arm 9 and below the flange 5. The horizontal shaft 10 rotates with the pressure cover 4 and abuts against the arc-shaped protrusions 8, so that the pressure cover 4 is pressed tightly against the connecting cover 3. The cylinder 1 is provided with a limiting member 11 that can drive the horizontal shaft 10 to keep in contact with the arc-shaped protrusions 8.

[0020] Specifically, the sealing cover is composed of a connecting cover and a pressure cover. The connecting cover is used to seal the opening on the cylinder body, while the pressure cover rotates relative to the connecting cover, causing the horizontal shaft on the pressure cover and located below the flange to rotate as well. The horizontal shaft rotates and abuts against the arc-shaped protrusion, causing the pressure cover to move downward relative to the connecting cover and press tightly against the connecting cover as it rotates. With the help of the limiting component, the horizontal shaft is kept in contact with the arc-shaped protrusion, thus achieving a tight installation connection between the sealing cover and the cylinder body. When disassembling, simply release the limiting component and rotate the pressure cover to make the horizontal shaft disengage from the arc-shaped protrusion and rotate it to the positioning notch of the flange, thus achieving the disassembly and separation of the sealing cover and the cylinder body.

[0021] Furthermore, the limiting member 11 includes a connecting seat 12 located on one side of the cylinder 1. The upper side of the connecting seat 12 has a recessed groove. A limiting rod 13 is movably arranged in the groove. A spring 14 is arranged in the groove, and the spring 14 abuts against the limiting rod 13 and the bottom of the groove.

[0022] Specifically, the limiting rod is kept in a connected state by a spring protruding above the connecting seat. When the horizontal shaft rotates with the pressure cover to the side of the limiting rod, the user can press the limiting rod to make it move down. After the horizontal shaft rotates past the limiting rod, it comes into contact with the arc-shaped protrusion, thus forming a connection state in which the horizontal shaft is clamped between the arc-shaped protrusion and the limiting rod, thereby causing the horizontal shaft to remain in contact with the arc-shaped protrusion.

[0023] Furthermore, the limiting component 11 also includes a screw 15 and a guide shaft 16 arranged coaxially. The screw 15 is rotatably disposed on one side of the cylinder 1. The connecting seat 12 is respectively fitted onto the screw 15 and the guide shaft 16, and the connecting seat 12 is threadedly connected to the screw 15. A knob 17 is provided at one end of the screw 15.

[0024] Specifically, the screw, guide shaft, and connecting seat work together so that when the user rotates the screw, the connecting seat can be moved, thereby adjusting the position of the limiting rod. This allows the limiting rod to more tightly contact one side of the horizontal shaft, maintaining the stability of the horizontal shaft clamped between the arc-shaped protrusion and the limiting rod, effectively preventing loosening.

[0025] Furthermore, a pin hole 18 is provided on one side of the limiting rod 13 and located within the groove, and a through hole 19 is provided on one side of the connecting seat 12 corresponding to the pin hole 18. A pin (not shown in the figure) is inserted between the through hole 19 and the pin hole 18. Specifically, by adding a pin inserted between the through hole and the pin hole, the limiting rod is kept in a connected state that protrudes outward above the connecting seat, thereby increasing the structural firmness of the limiting rod abutting against the side wall of the transverse shaft.

[0026] Furthermore, the horizontal shaft 10 is threadedly connected to the connecting arm 9. This allows for the detachment and reassembly of the horizontal shaft, facilitating installation, maintenance, and replacement.

[0027] Furthermore, a fixed shaft 31 is provided at the center of the upper side of the connecting cover 3, and the pressure cover 4 is movably sleeved on the fixed shaft 31 so that the pressure cover 4 can rotate around the fixed shaft 31 and move axially along the fixed shaft 31.

[0028] Furthermore, the width of the positioning notch 6 is greater than the diameter of the horizontal axis 10.

[0029] Furthermore, a sealing ring is provided between the connecting cover 3 and the cylinder 1.
