Description

Technical Field

[0001] The utility model relates to the technical field of filter element replacement devices, in particular to a filter element replacement mechanism for a water purification vehicle. Background Art

[0002] A water purification vehicle is a mobile water treatment system typically mounted on a truck or trailer, capable of rapid deployment to provide on-site water purification where needed. It is primarily used for emergency water supply, disaster relief, military operations, and the provision of clean drinking water in remote areas or temporary locations. It can quickly transform contaminated water sources (such as rivers, lakes, and wells) into safe drinking water that meets drinking standards.

[0003] The filter element replacement mechanism for water purification vehicles is a mechanism designed specifically for water purification vehicles. It is used to quickly and efficiently replace the filter element in the water treatment system. This device usually removes the filter element through an electric sleeve, which has the advantages of reducing the need for operators and significantly improving work efficiency.

[0004] In the prior art, the filter element replacement mechanism for water purification vehicles usually does not have a torque adjustment function. If the torque provided by the electric sleeve is too large, the filter element may be overtightened, which may not only cause damage to the filter element or filter housing, but also make the next replacement more difficult.

The outer wall of the adjusting sleeve 110 is provided with a pointer 115, and the outer wall of the mounting shell 101 is provided with a scale line 114. The cooperation between the pointer 115 and the scale line 114 allows the staff to accurately adjust the torque. A number of sliding balls 113 are movably installed on the top of the adjusting disk 111, and the sliding balls 113 allow the extrusion disk 107 to rotate flexibly on the top of the adjusting disk 111. A rubber sleeve 116 is fixedly installed on the inner wall of the disassembly disk 106, and the rubber sleeve 116 prevents the inner wall of the disassembly disk 106 from directly contacting the outer wall of the filter element to reduce wear.

[0024] The specific implementation method is as follows: the motor 102 drives the gear 103 to rotate, and the gear 103 drives the toothed disc 104 to rotate, and the cooperation between the transmission teeth 105 and the locking ball 109 drives the disassembly disc 106 to rotate, and the disassembly disc 106 is used to clamp the outer wall of the filter element to install and disassemble the filter element.

[0025] See also Figure 1-5The utility model provides a technical solution: a filter element replacement mechanism for a water purification vehicle, the conveying mechanism 2 includes a mounting seat 201, and a mechanical arm 202 is fixedly installed on the top of the mounting seat 201, a mounting frame 203 is fixedly installed on one side of the mechanical arm 202, and a clamping claw 204 is fixedly installed on one side of the mounting frame 203, the disassembly mechanism 1 is fixedly installed on one side of the mounting frame 203, and the conveying mechanism 2 is arranged at the bottom of the clamping claw 204, and a visual sensor 205 is fixedly installed on the bottom of the mounting frame 203, and a protective pad 206 is fixedly installed on the inside of the clamping claw 204, which prevents the clamping claw 204 from directly contacting the outer wall of the filter element through the protective pad 206 to reduce wear, and a distance sensor 207 is fixedly installed on the bottom of the mounting frame 203, which helps the conveying mechanism 2 to more accurately locate the filter element to be replaced, the new element storage area and the old element recovery area through the distance sensor 207. It cooperates with the visual sensor 205 to accurately locate the area to be replaced, the new element storage area and the old element recovery area to ensure that each replacement is accurate.

The visual sensor 205 facilitates the device to identify the area to be replaced, the new core storage area, and the old core recovery area.
