Description

Technical Field

[0001] This utility model belongs to the technical field of filter separator maintenance tools, and in particular relates to an extension rod for disassembling and assembling filter element trays of filter separators. Background Technology

[0002] The housing design of filter separators is typically long and slender, requiring the removal of the filter element tray for inspection, cleaning, and maintenance. Currently, operators often lack the arm length to reach the filter element tray's fixing screws and tighten or loosen them. Furthermore, nuts easily fall into the housing during disassembly, making them difficult to spot and remove. Additionally, without removing the tray, it's impossible to observe the blind spots beneath it and confirm the condition of the differential pressure gauge's connecting pipe, causing numerous inconveniences and impacting maintenance efficiency and quality.

[0003] Therefore, we propose an extension rod for disassembling and assembling filter cartridge trays for filter separators. Utility Model Content

[0004] The purpose of this utility model is to provide an extension rod for disassembling and assembling filter element trays of filter separators, which solves the problems of insufficient operating distance, easy falling off of nuts, and difficulty in observing blind spots in the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an extension rod for disassembling and assembling a filter separator cartridge tray, comprising an extension rod, a sleeve, and a strong magnet. The sleeve is fixedly connected to one end of the extension rod, and the strong magnet is embedded in the internal cavity of the sleeve. The inner diameter of the sleeve is adapted to the screw head size of the filter separator cartridge tray, the adsorption surface of the strong magnet is flush with the open end of the sleeve, and a gripping part is fixed to one end of the extension rod.

[0007] In one embodiment, the extension rod consists of an extension tube and an extension column. The extension tube has several limiting holes symmetrically opened on its circumferential side. The extension column has a groove symmetrically opened on its circumferential side at one end. A spring is fixed in the groove. A limiting column is fixed at one end of the spring. The length of the extension rod is 50-150cm.

[0008] In one embodiment, the shape and size of the extension tube are adapted to the extension column, and the extension tube and the extension column cooperate with each other.

[0009] In one embodiment, the shape and size of the limiting post are adapted to the limiting hole, and the limiting post and the limiting hole are engaged.

[0010] In one embodiment, the strong magnet is fixed inside the sleeve by adhesive or interference fit, and the sleeve is fixedly connected to the lower end of the extension column.

[0011] In one embodiment, a rubber anti-slip sleeve is provided on the peripheral side of the grip portion, and the grip portion is fixedly connected to the upper end of the extension tube.

[0012] In one embodiment, the extension rod is made of stainless steel and the sleeve is made of carbon steel.

[0013] In one embodiment, the strong magnet is made of neodymium iron boron and is bonded to the bottom of the sleeve with epoxy adhesive.

[0014] This utility model has the following beneficial effects:

[0015] 1. Solving the problem of insufficient operating distance: The length of the extension rod can be adjusted within the range of 50-150cm. Through the cooperation of the extension tube and the extension column, as well as the locking and fixing of the limiting hole and the limiting column, the length can be flexibly adjusted according to the slender structure of the filter separator shell. This allows operators to easily reach the fixing screws of the filter tray without having to go deep into the equipment to complete the tightening and loosening operation, avoiding the operating difficulties caused by insufficient arm length.

[0016] 2. Preventing nuts from falling off and being lost: The neodymium iron boron magnet embedded inside the sleeve has its adsorption surface flush with the opening end of the sleeve. When the screw head is being put on, it can firmly hold the nut. Whether removing the nut during disassembly or placing the nut during installation, it can effectively prevent the nut from falling into the housing, reducing maintenance delays and cost waste caused by lost nuts.

[0017] 3. Facilitates observation and inspection of blind spots: This extension rod can not only be used for disassembly and assembly operations, but also, without disassembling the pallet, the operator can hold the extension rod with a grip and insert one end of the sleeve into the equipment. With the support of the sleeve and the extension of the extension rod, the operator can observe the blind spot area under the pallet. At the same time, it is convenient to check the integrity of the differential pressure gauge connecting pipe, promptly detect potential faults, and improve the comprehensiveness and accuracy of maintenance.

[0018] 4. Stable and durable operation: The extension rod is made of stainless steel, which has good strength and corrosion resistance and can adapt to the complex environment during filter separator maintenance; the sleeve is made of carbon steel, which has a sturdy structure and can stably fit the screw head; the rubber anti-slip sleeve around the grip increases the friction between the hand and the tool, prevents slippage during operation, improves operational stability, extends the service life of the tool, and reduces the frequency of tool replacement.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] Example 2

[0041] Please see Figures 1-5As shown in the figure, this embodiment illustrates a method for using an extension rod to disassemble and assemble a filter separator cartridge tray. The specific operation is as follows:

[0042] 1. Length Adjustment Operation: Adjust the length of the extension rod 1 according to the depth of the filter separator and the distance between the operator and the equipment. During adjustment, press the limiting post 16 in the groove 14 of the extension column 12, causing the limiting post 16 to compress the spring 15 and retract into the groove 14. At this time, the extension tube 11 and the extension column 12 can be pulled to change their overlapping length. When the length is adjusted to a suitable position to ensure that the filter tray screws can be reached, release the limiting post 16. The spring 15 returns to its original position, pushing the limiting post 16 out and into the corresponding limiting hole 13 of the extension tube 11, thus fixing the length of the extension rod.

[0043] 2. Filter Cartridge Screw Removal Procedure: The operator holds the grip 4 and aligns the open end of the sleeve 2 with the head of the fixing screw on the filter cartridge tray, slowly fitting it in to ensure the screw head is fully inside the sleeve 2. At this point, the strong magnet 3 will attract the nut. Then, rotate the grip 4 clockwise or counterclockwise according to the screw's rotation direction. Through the force transmitted by the extension rod 1, the screw will rotate until it loosens. After the screw loosens, continue to maintain the sleeve 2 and screw engagement, and slowly pull the extension rod to remove the screw and nut together. Due to the attraction of the strong magnet 3, the nut will not fall off.

[0044] 3. Installing the filter tray screws: Place the screws to be installed into the sleeve 2; the strong magnet 3 will attract and secure the screws. Holding the handle 4, align the screw with the screw hole on the filter tray, slowly insert and align it, then rotate the handle 4 in the opposite direction to screw the screw into the hole. After the screw is tightened to the appropriate degree to ensure the tray is securely fixed, continue rotating the handle 4 until the screw is completely secured. Then gently pull the extension rod 1 to separate the sleeve 2 from the screw head, completing the installation.

[0045] 4. Dead-angle observation and inspection operation: Without disassembling the tray, if it is necessary to observe the dead-angle area under the tray or inspect the differential pressure gauge connecting pipe, hold the grip part 4 and slowly insert one end of the sleeve 2 into the filter separator. By adjusting the angle and position of the extension rod 1, the sleeve 2 is directed towards the area to be observed. The operator observes the appearance of the dead-angle area under the tray and the differential pressure gauge connecting pipe through the extension direction of the extension rod to determine whether there are any problems such as damage or blockage.
