Description

Technical Field

[0001] This utility model relates to the field of electrostatic adsorption filter elements, and in particular to an electrostatic adsorption filter element for sludge and oil. Background Technology

[0002] An electrostatic filter element is a device installed in an electrostatic oil filter. It is used to release electrostatic current to adsorb and filter oil, and it is quite common in daily life.

[0003] Existing technologies, such as the utility model patent with publication number CN217961606U, disclose a static-conducting filter element and fuel filter. This patent employs a filter element frame and a filter medium surrounding the frame. One end of the filter medium is connected to an annular end cap made of conductive material, and the other end is connected to a base. The inner opening of the annular end cap extends axially with an annular protruding wall. The inner surface of the annular protruding wall has a radially inwardly extending conductive portion for rigid connection with an external conductive device. In this utility model's technical solution, during filter element use, the conductive portion on the annular protruding wall can stably connect with an external conductive device, allowing the external conductive device to conduct static electricity and release it to the outside, thereby dissipating the static electricity generated by the filter medium.

[0004] The inventors discovered through daily use that existing filter elements are mostly welded or fixed with multiple bolts. Therefore, when the filter element needs replacement, the entire filter must be removed, making replacement time-consuming and costly. In addition to the cost of the filter element itself, the replacement process may also require disassembling, inspecting, and cleaning the equipment, which means additional labor and time costs. This is especially problematic in high-load production environments where equipment frequently needs to be shut down for filter element replacement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrostatic adsorption filter element for oily waste.

[0006] To solve the above-mentioned technical problems, this utility model provides an electrostatic adsorption filter element for oily waste, comprising: a shell and an installation structure. A filter element body is disposed inside the shell, and the filter element body is connected to the shell via the installation structure. The installation structure is provided on the arc surface of the filter element body. The installation structure includes several connecting grooves, all of which are formed on the filter element body. A top plate is slidably connected inside each connecting groove.

[0008] Preferably, a plurality of handles are fixedly connected to the upper end of the slide rod, and the plurality of handles are evenly distributed on the slide rod.

[0009] The effect achieved by the above components is that when it is necessary to pull the slide bar to move, the handle can also be pulled directly, and the handle will drive the slide bar to move, making it more convenient to pull the slide bar.

[0010] Preferably, a telescopic rod is fixedly connected to the side of the top plate near the connecting groove, the telescopic rod is fixedly connected to the connecting groove, and the spring is sleeved on the arc surface of the telescopic rod.

[0011] The effect achieved by the above components is that the telescopic rod can limit the spring, prevent the spring from deforming during use, and improve the service life of the spring.

[0012] Preferably, a protective shell is slidably connected to the arc surface of the outer shell, and the protective shell is a stainless steel shell.

[0013] The effect achieved by the above components is that the protective shell can protect the connecting groove and the slot, preventing oil from flowing out of the connecting groove and the slot when the filter element is used.

[0014] Preferably, the card plate is a silicone plate, and the cross-section of the card plate is rectangular.

[0015] The effect achieved by the above components is that the silicone material has a certain degree of softness, the card plate can deform when separated from the top plate, and the filter body can be easily replaced.

[0016] Preferably, a plurality of the fixing rods are evenly distributed within the filter element body, and the fixing rods are stainless steel rods.

[0017] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting when used in a short period of time.

[0018] Compared with related technologies, the electrostatic adsorption filter element for oily waste provided by this utility model has the following beneficial effects:

[0019] By designing an installation structure, existing technologies typically use welding or multiple bolts to fix filter elements. Therefore, replacing the filter element requires disassembling the entire filter, making replacement time-consuming and costly. In addition to the cost of the filter element itself, the replacement process may also require disassembly, inspection, and cleaning of the equipment, resulting in additional labor and time costs. Especially in high-load production environments where equipment frequently needs to be shut down for filter element replacement, this device allows for convenient and rapid disassembly and assembly of the filter element, making the replacement process quicker and simpler, thus significantly reducing equipment downtime. Furthermore, in industrial production, especially under high-load environments requiring continuous operation, rapid filter element replacement maximizes equipment operating efficiency, avoids production interruptions due to filter element replacement, and minimizes production losses caused by downtime.

The two ends of the springs 310 are fixedly connected to the top plate 305 and the connecting groove 311, respectively. A connecting plate 308 is fixedly connected to the lower end of the outer shell 1. An inclined plate 307 is fixedly connected to the upper surface of the connecting plate 308. Several locking plates 306 are fixedly connected to the inner wall of the locking groove 312. The locking plates 306 are locked to the top plate 305. The lower end of the top plate 305 abuts against the connecting plate 308. Several fixing rods 301 are fixedly connected inside the filter element body 2. A sleeve rod 302 is fixedly connected to one end of the fixing rods 301 that is close to each other. A sliding rod 313 is slidably connected to the inner wall of the sleeve rod 302. A damping is provided between the sliding rod 313 and the sleeve rod 302. When it is necessary to install the outer shell 1 and the filter element body 2, the slide rod 313 is pulled to move. The slide rod 313 slides on the inner wall of the sleeve rod 302. The sleeve rod 302 drives the fixing rod 301 to move. The fixing rod 301 drives the filter element body 2 to move. The filter element body 2 drives the connecting groove 311 to move. The connecting groove 311 drives the spring 310 to move. The spring 310 drives the clamping plate 306 to move. When it moves to the lower end, the inclined plate 307 drives the top plate 305 to expand outward. The top plate 305 is inserted into the clamping groove 312. The top plate 305 drives the spring 310 to stretch. After moving to the appropriate position, the clamping plate 306 is inserted into the top plate 305 for fixation, thereby completing the installation of the filter element body 2. Several handles 303 are fixedly connected to the upper end of the slide rod 313. The several handles 303 are evenly distributed on the slide rod 313.
