Description

Technical Field

[0001] This utility model belongs to the technical field of cathode wire for electric filters, and specifically relates to a fastening device for connecting and fastening the cathode wire and hook of an electric filter. Background Technology

[0002] The electrofiltration unit is a key piece of equipment in an acetylene plant. A malfunction in this unit can cause the entire pyrolysis unit to shut down, severely impacting the stable operation and continuous production of the plant. Its main process is to ionize pyrolysis gas containing carbon black particles under a high-voltage electric field, ensuring that the gas entering the pyrolysis gas compressor maintains a high level of cleanliness to ensure the smooth operation of subsequent processes. The cathode wire, as a key component of the electrofiltration unit, plays a crucial role in introducing 72KV high-voltage direct current.

[0003] In practical use, frequent shutdowns for maintenance due to cathode wire malfunctions not only impact the company's economic benefits but also significantly increase the operational risks for maintenance personnel. Replacing the wire inside the filter is a confined space operation with substantial risks. The original fixing method has obvious defects; under the impact of 10,000 cubic meters per hour of airflow inside the filter, prolonged exposure can easily cause the wire to break. Utility Model Content

[0004] The purpose of this invention is to provide a fastening device for the cathode wire and hook of an electric filter, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fastening device for connecting and fastening the cathode wire and hook of an electric filter, comprising an integrally formed hook part, a hanging rod part, and a threaded section, wherein the hook part, the hanging rod part, and the threaded section are arranged sequentially from top to bottom, the threaded section has an external thread, an anti-loosening nut is screwed onto the external thread and is sleeved on the outside of the threaded section, the threaded section has a fixing groove, and the cathode wire is placed inside the fixing groove, the fixing groove extends to the hanging rod part, and a clamping component is provided in the fixing groove.

[0006] Preferably, the clamping assembly includes a clamping bolt and a clamping plate. The clamping plate is installed at the end of the clamping bolt and is located inside the fixing slot, and can abut against the cathode wire. The hanging rod has a screw hole through which the clamping bolt can pass.

[0007] Preferably, a detachable extension rod is installed at the bottom of the hook portion.

[0008] Preferably, a fixing bolt is provided through the extension rod and the hanging rod, and a fixing nut is screwed onto the end of the fixing bolt.

[0009] Preferably, the top of the extension rod is provided with a threaded rod, the bottom end of the hook part is provided with a threaded hole that matches the threaded rod, and the extension rod and the hook part are screwed together by the threaded rod and the threaded hole.

[0010] Preferably, both the extension rod and the hook portion are provided with fixing holes through which fixing bolts can pass, and the fixing holes on the fixing bolts always correspond to the fixing holes on the hook portion.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model improves the connection method of the cathode wire hook of the electric filter by setting a slotted thread section on the hanging rod and cooperating with the anti-loosening nut, changing the original iron sheet wrapped connection to the nut connection with the anti-loosening device. It completely solves the electric filter shutdown phenomenon caused by wire breakage and hook wear that often occurs with the original hook. The improvement effect is very significant, the equipment failure rate drops sharply to zero failure, and the improvement has achieved good economic and social benefits.

[0013] (2) By setting up a clamping component, the clamping plate and clamping bolts work together to make the clamping plate press against the cathode wire, further fixing the cathode wire and ensuring that the cathode wire will not fall out of the fixing slot, making the installation more stable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, this utility model provides the following technical solution: a fastening device for connecting and fastening the cathode wire and hook of an electric filter, including an integrally formed hook part 3, a hanging rod part 5 and a threaded section 7, the hook part 3, the hanging rod part 5 and the threaded section 7 are arranged sequentially from top to bottom, the threaded section 7 has an external thread, an anti-loosening nut 9 is screwed on the external thread and is sleeved on the outside of the threaded section 7, the threaded section 7 has a fixing slot 10, and the cathode wire 8 is placed inside the fixing slot 10. The fixing slot 10 extends to the hanging rod part 5 and a clamping component is provided in the fixing slot 10.

[0022] To address the above, when using the cathode wire fastening device for this electrofilter, pass one end of the cathode wire 8 through the anti-loosening nut 9 and the fixing slot 10 in sequence, and place the cathode wire 8 in the fixing slot 10. After placement, use the clamping assembly to fix the cathode wire 8 in the fixing slot 10, and screw the anti-loosening nut 9 into the threaded section 7 to prevent the cathode wire 8 from falling out of the fixing slot 10, making the installation more stable. After the cathode wire 8 is installed, simply hang the hook part 3 inside the electrofilter.

[0023] Specifically, such as Figures 2-4 As shown, in one embodiment, regarding the above-described clamping assembly:

[0024] The clamping assembly includes a clamping bolt 6 and a clamping plate 11. The diameter of the clamping plate 11 is always smaller than the radius of the fixed slot 10, ensuring that the clamping plate 11 can rotate within the fixed slot 10. The clamping plate 11 is installed at the end of the clamping bolt 6 and is located inside the fixed slot 10, and can abut against the cathode wire 8. The hanging rod part 5 is provided with a screw hole through which the clamping bolt 6 can pass.

[0025] In response to the above, when using this clamping assembly, after the cathode wire 8 is placed in the fixing slot 10, the clamping bolt 6 is rotated so that the clamping bolt 6 and the clamping plate 11 abut against the cathode wire 8, further tightening the cathode wire 8.

[0026] Specifically, in order to ensure that the hook part 3 does not slip out, in this utility model, a detachable extension rod 1 is installed at the bottom of the hook part 3;

[0027] A fixing bolt 2 is provided through the extension rod 1 and the hanging rod part 5, and a fixing nut 4 is screwed onto the end of the fixing bolt 2;

[0028] Both the extension rod 1 and the hook part 3 are provided with fixing holes through which the fixing bolt 2 can pass, and the fixing holes on the fixing bolt 2 always correspond to the fixing holes on the hook part 3, ensuring that the fixing bolt 2 can pass through the fixing holes.

[0029] To address the above, after the hook part 3 is hung inside the filter, the fixing bolt 2 is passed through the fixing hole, and the fixing nut 4 is screwed onto the end of the fixing bolt 2, so that the hook part 3 forms a closed ring, ensuring that the hook part 3 will not slip off.

[0030] In addition, such as Figure 1 and Figure 5 As shown, in this utility model, the top of the extension rod 1 is provided with a threaded rod 12, and the bottom end of the hook part 3 is provided with a threaded hole that matches the threaded rod 12. The extension rod 1 and the hook part 3 are connected by screwing the threaded rod 12 and the threaded hole. This allows the staff to install and remove the extension rod 1 as needed. During installation, the extension rod 1 is rotated so that the threaded rod 12 at the top of the extension rod 1 is screwed into the threaded hole, thus completing the installation of the extension rod 1.
