Description

Technical Field

[0001] This utility model relates to the field of preheater fin technology, specifically a corrosion-resistant C5 inner cylinder fin. Background Technology

[0002] In order to reduce wear on the cyclone in the preheater, a hanging plate structure is usually installed on the inner wall of the cyclone. The hanging plate replaces the cyclone and contacts the cement raw material, thereby reducing the wear on the cyclone. However, the existing inner cylinder hanging plates still have certain defects in use, such as:

[0003] Publication No. CN218295790U proposes a ceramic mounting plate for the inner cylinder of an acid and alkali corrosion resistant preheater. The mounting plate includes a mounting plate whose front side is fixedly connected to the back side of an insert block. The insert block is inserted into a slot to connect the upper and lower mounting plates. A locking block on the upper surface of the mounting plate is inserted into a slot on the lower surface of the adjacent mounting plate to assemble the upper and lower mounting plates. A sealing plate seals the gap at the connection point of the two adjacent mounting plates and is inserted into a fixing frame. Bolts pass through the sealing plate and fixing frame to connect to the inner cylinder. A screw connects the fixing threaded sleeves below the fixing frames of the two adjacent mounting plates, thus preventing gaps between the two adjacent mounting plates after connection. This solves the problem in existing devices where multiple bolts are used to fix the mounting plates to the inner wall of the cyclone separator, leading to bolt corrosion and gaps between the mounting plates, affecting the normal operation of the preheater.

[0004] The aforementioned document states that corrosion is prevented by sealing the gaps at the snap-fit ​​joints and concealing the bolt connection structure. However, this does not enhance the corrosion resistance of the hanging plate itself. Therefore, a corrosion-resistant C5 inner cylinder hanging plate is proposed to address the above issues.

The baffle plate abuts against the front of the hanging plate body. A storage slot is provided at the front of the H-shaped insert plate.

[0012] Preferably, a baffle plate is abutted against the baffle plate through the opening, and an arc-shaped slide rail is connected to the back of the baffle plate. An arc-shaped slide plate slides through the arc-shaped slide rail and is connected to the inner wall of the storage slot.

[0013] Preferably, a tension spring is connected to the back of the baffle, and the other end of the tension spring is connected to the inner wall of the storage groove.

[0014] Preferably, the inner wall of the storage slot is connected to a U-shaped plate, and a plug rod slides through one side of the inner wall of the storage slot. The plug rod is engaged in the insertion hole, and the inside of the plug rod is connected to a bidirectional threaded rod through a threaded groove.

[0015] Preferably, a horizontal bevel gear is meshed with the lower part of the longitudinal bevel gear, and a handle is connected to the lower part of the horizontal bevel gear. The handle rotates through the inner wall of the U-shaped plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This corrosion-resistant C5 inner cylinder hanging plate, based on the inherent corrosion resistance of the silicon nitride ceramic hanging plate, adds a phenolic resin organic binder layer, a wear-resistant chromium plating layer, an alumina layer, a silicon carbide layer, and an aluminosilicate layer, increasing corrosion and wear resistance, thus making the inner cylinder hanging plate corrosion-resistant. By prying open the baffle, rotating the handle to drive the bidirectional threaded rod to rotate inside the insertion rod, driving the insertion rod to be pulled out of the insertion hole, and then pulling the baffle forward to remove the H-shaped insertion plate from the T-shaped slot, the hanging plate body can be removed for replacement, thus making the inner cylinder hanging plate easy to replace. The specific details are as follows:

[0017] 1. Based on the inherent corrosion resistance of the silicon nitride ceramic pads, the phenolic resin organic binder layer and the wear-resistant chromium plating layer increase corrosion resistance and wear resistance, the alumina layer increases corrosion resistance, wear resistance and high temperature resistance, the silicon carbide layer increases corrosion resistance and thermal shock resistance, and the aluminosilicate layer increases heat resistance and corrosion resistance. Together, they protect the silicon nitride ceramic pads, thereby making the inner cylinder pads corrosion-resistant.

[0018] 2. By prying open the baffle, and then rotating the handle to drive the horizontal bevel gear to drive the vertical bevel gear to rotate, thereby driving the bidirectional threaded rod to pull the insert rod out of the insertion hole. Then, pull the baffle forward to remove the H-shaped insert plate from the T-shaped slot, separate the two adjacent sets of hanging plate bodies, remove the hanging plate bodies for replacement, and thus make the inner cylinder hanging plate easy to replace.
