Description

Technical Field

[0001] This utility model relates to the field of insert gate technology, specifically an anti-jamming insert gate for the ash hopper discharge port. Background Technology

[0002] In electrostatic precipitator (ESP) systems, the slide gate at the ash hopper discharge port is a crucial component for controlling dust discharge. It opens and closes the discharge port by sliding the slide plate within the slide plate slot, thus precisely controlling dust discharge. However, the dust particles discharged from the ESP ash hopper are fine and highly viscous. During long-term operation, this dust continuously accumulates in the slide plate slot. Over time, the dust accumulation worsens, causing a sharp increase in the resistance to the slide plate sliding within the slot, leading to obstruction and blockage. Once this occurs, it directly disrupts the continuity of ash discharge operations, preventing stable and orderly dust discharge. More seriously, when the blockage worsens, the slide plate may become completely unable to open or close properly, ultimately forcing the entire system to shut down. This not only disrupts the production rhythm but also significantly increases equipment maintenance costs.

[0003] However, in the existing technology, the slide gate usually relies on the slide plate itself to clean up the accumulated dust, which has limited effect. When the dust accumulation is serious, the slide gate needs to be disassembled for cleaning, which is cumbersome and affects production. Therefore, we need a slide gate for the dust hopper discharge port that prevents jamming. Utility Model Content

[0016] 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.

[0017] This utility model embodiment provides a jam-proof ash hopper discharge port insert door, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a fixed frame 1, a dust discharge assembly 2 on the top of the fixed frame 1, a door panel body 3 fixedly connected to the bottom of the fixed frame 1, and a maintenance assembly 4 at the bottom of the door panel body 3. The dust discharge assembly 2 includes a pneumatic valve 201, which is located on the top of the fixed frame 1. A valve stem 202 is fixedly connected to the output end of the pneumatic valve 201, a connecting plate 203 is fixedly connected to one end of the valve stem 202, an insertion plate 204 is fixedly connected to the bottom of the connecting plate 203, wear-resistant strips 205 are fixedly connected to both sides of the insertion plate 204, a door panel groove 206 is fixedly connected to the inner wall of the door panel body 3, and a dust discharge port 207 is opened on one side of the door panel body 3. When cleaning the door panel body 3... The pneumatic valve 201 can be activated to move the valve stem 202, which in turn moves the connecting plate 203. This, in turn, moves the insertion plate 204, causing the insertion plate 204 to slide along the inner wall of the insertion plate groove 206 with the wear-resistant strips 205 on both sides. This reduces sliding wear, minimizes component wear caused by jamming, and extends the service life of the equipment. At this time, because the ash discharge port 207 is tilted in this direction, the accumulated ash is discharged through the ash discharge port 207 under the thrust and gravity of the insertion plate 204. The tilted ash discharge port 207 is linked to the closing action of the insertion plate 204. The thrust of the insertion plate 204 assists in ash discharge, requiring no additional power. This results in high ash discharge efficiency, reduces ash residue, and completes part of the cleaning.

[0018] Furthermore, such as Figure 2As shown, the main body 3 of the insert door is provided with multiple ash discharge ports 207 on one side, and the ash discharge ports 207 are inclined towards the opening direction of the insert plate 204. When the main body 3 of the insert door is closed, it pushes the accumulated ash to move in the opening direction, and under the action of thrust and gravity, it is discharged through the ash discharge ports 207, reducing residue and improving the ash discharge effect.

[0019] Furthermore, such as Figure 2 and Figure 3 As shown, wear-resistant strips 205 are fixedly connected to both sides of the insertion plate 204, and the two wear-resistant strips 205 can move along the inner wall of the insertion plate groove 206. This allows the insertion plate 204 to reduce sliding wear by relying on the wear-resistant strips 205 on the edge, reduce component wear caused by jamming, and improve the service life of the equipment.

[0020] Furthermore, such as Figure 2 As shown, the valve stem 202 forms a movable structure with the insertion plate 204 via the connecting plate 203. The top of the connecting plate 203 is fixedly connected to one end of the valve stem 202, and the bottom of the connecting plate 203 is fixedly connected to the top of the insertion plate 204. This allows the connecting plate 203 to push the insertion plate 204 when the valve stem 202 pushes the connecting plate 203.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, the maintenance component 4 includes a sealing plug 401, which is installed at the bottom of the insert door body 3. A cleaning hole 402 is provided at the bottom of the insert door body 3. A sealing gasket 403 is fixedly connected to one side of the sealing plug 401. The sealing plug 401 is pulled out, and then connected to the cleaning hole 402 of the insert door body 3 through two compressed air pipes. The airflow is used to periodically remove floating dust and fine dust. The blowing frequency and flow rate can be adjusted by the control valve to reduce dust accumulation from the source. The cleaning hole 402 allows direct contact with the inside of the insert door body 3, and cleaning can be completed without disassembling the insert door body 3, reducing maintenance time and workload. After cleaning, the sealing plug 401 is installed on the cleaning hole 402, so that one side of the sealing gasket 403 presses the bottom of the insert groove 206 to complete the seal.

[0022] Furthermore, such as Figure 4 As shown, two cleaning holes 402 are provided at the bottom of the slide door body 3. The two cleaning holes 402 are distributed at intervals along the length of the slide groove 206. This allows the two cleaning holes 402 of the slide door body 3 to be connected through two compressed air pipes, so that the airflow can be used to periodically remove floating dust and fine dust, thereby improving the cleaning effect.

[0023] Furthermore, such as Figure 4 and Figure 5As shown, the main body 3 of the door panel forms a sealing structure with the sealing plug 401 and the cleaning hole 402. The size of the sealing plug 401 matches the size of the cleaning hole 402, and the outer wall of the sealing plug 401 fits into the inner wall of the cleaning hole 402. This allows the sealing plug 401 to be pulled out directly to clean stubborn dust without disassembling the main body 3 of the door panel when the dust accumulation is severe, thus improving the cleaning effect.

[0024] Furthermore, such as Figure 5 As shown, the sealing plug 401 forms a sealing structure with the door body 3 through the sealing gasket 403, and one side of the sealing gasket 403 is fixedly connected to one side of the sealing plug 401, and the other side of the sealing gasket 403 is attached to the bottom of the door body 3, so that the sealing plug 401 can tightly seal the door body 3 by relying on the sealing gasket 403, thereby improving the sealing effect of the door body 3.

[0025] Working principle: When cleaning the main body 3 of the slide gate, the pneumatic valve 201 can be activated to move the valve rod 202. The valve rod 202 moves the connecting plate 203, which in turn moves the insertion plate 204. This causes the insertion plate 204 to slide along the inner wall of the slide groove 206, reducing sliding wear, minimizing component wear caused by jamming, and extending the equipment's service life. At this time, because the ash discharge port 207 is tilted in this direction, the accumulated ash is discharged through the ash discharge port 207 under the thrust and gravity of the insertion plate 204. The tilted ash discharge port 207 is linked to the closing action of the insertion plate 204, utilizing... The insertion plate 204 assists in ash removal with thrust, requiring no additional power. The ash removal efficiency is high, reducing ash residue and completing part of the cleaning. The sealing plug 401 is then removed, and the cleaning hole 402 of the insertion plate door body 3 is connected through two compressed air pipes. The airflow is used to periodically remove floating ash and fine ash. The blowing frequency and flow rate can be adjusted by the control valve to reduce ash accumulation from the source. The cleaning hole 402 allows direct contact with the inside of the insertion plate door body 3, and cleaning can be completed without disassembling the insertion plate door body 3, reducing maintenance time and workload. After cleaning, the sealing plug 401 is installed on the cleaning hole 402, so that one side of the sealing gasket 403 presses against the bottom of the insertion plate groove 206 to complete the seal.
