Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to an improved ventilation fan for a gasification furnace. Background Technology

[0002] In the gasifier, fuel first enters the nozzle through an oil pipe and is heated. When the temperature reaches 65°C, the fuel begins to change from liquid to gas, then flows into the combustion chamber and is ignited by an open flame. A blower at the bottom of the burner continuously blows air into the combustion chamber, sending the fuel into the combustion chamber for complete combustion. A ventilation fan installed inside the gasifier delivers air or other oxygen-containing gases into the gasifier, providing the necessary oxygen for the gasification reaction. The oxygen reacts with the fuel in the furnace, causing combustion or partial oxidation, providing heat and reaction conditions for subsequent gasification. However, in existing technology, when the ventilation fan draws oxygen from the outside air for delivery, the air contains dust. This can cause damage to the bearings and impeller inside the ventilation fan over prolonged use, thus reducing its service life.

[0003] An improved ventilation fan for a gasifier is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide an improved ventilation fan for a gasification furnace, in order to solve the problem mentioned in the background art that when the current ventilation fan draws oxygen from the outside air for transportation, the air contains dust, which may cause damage to the bearings and impeller inside the ventilation fan after long-term use, thereby reducing the service life of the ventilation fan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved gasification furnace ventilation fan, comprising a body, wherein a smoke pipe is connected through one side of the top of the body;

[0006] A bellows is fixedly installed on one side surface of the main body, a fan is fixedly installed inside the bellows, mounting parts are fixedly connected to both sides of the fan, an air outlet pipe is fixedly installed on one side surface of the fan, a conveying pipe is fixedly installed on the other side surface of the fan, and an air inlet pipe is fixedly installed on the side surface of the conveying pipe that is away from the fan and passes through the bellows.

[0007] Also includes:

[0008] Limiting components are symmetrically arranged on both sides of the air inlet pipe away from the delivery pipe;

[0009] The limiting component includes a connecting rod that is fixedly connected to the air inlet pipe;

[0010] Among them, support rods are symmetrically installed on one side surface of the connecting rod. A limit box is fixedly connected to the side surface of the support rod away from the connecting rod. A compression spring is fixedly installed inside the limit box. A stabilizing rod is fixedly connected to the bottom surface of the compression spring. A pull rod is fixedly connected to the side surface of the stabilizing rod near the middle. A pulley is rotatably connected to the bottom surface of the stabilizing rod. The stabilizing rod is connected through the limit box. The pulley is connected through the air inlet pipe.

[0011] Preferably, the air inlet pipe has a baffle block inside, a filter element is attached to one side surface of the baffle block, and the filter element has symmetrical slots on the side surface near the baffle block, with a locking rod inside the slot.

[0012] Preferably, the side surface of the lever away from the slot is fixedly connected to the blocking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This improved gasification furnace ventilation fan, by setting up a filter element, can filter dust in the air, thereby reducing the amount of dust entering the fan and reducing damage to the bearings and impeller, thus extending the service life of the fan to a certain extent. At the same time, by setting up a limiting component, the installation and removal of the filter element can be made more convenient, thereby improving the replacement efficiency of the filter element. The specific details are as follows:

[0014] 1. By setting a limit component, when the filter element needs to be replaced, a tool is used to pull the lever, causing the lever to raise the stabilizing rod. The rising of the stabilizing rod then raises the pulley, simultaneously compressing the compression spring and causing it to deform. Once the pulley reaches a certain position and no longer obstructs the filter element, the filter element is pulled to separate from the blocking block, allowing for replacement. During filter element installation, after placing the filter element inside the conveying pipe, ensuring its outer wall fits against the inside of the pipe, the filter element is pushed. As it moves within the conveying pipe, it impacts the pulley. The filter element is compressed, and its left side is inclined, which allows the pulley to be compressed. This causes the pulley to lift the stabilizing rod, preventing the pulley from obstructing the filter element. After the filter element moves to a certain position, the slot and the rod engage, completing the filter installation. After the filter element is installed, with the pulley positioned to the right of the filter element and the filter element not lifting the pulley, the stabilizing rod descends under the action of the compression spring. The descent of the stabilizing rod causes the pulley to descend, thus limiting and obstructing the right side of the filter element. At the same time, the right side of the filter element is flat, preventing the pulley from being compressed. This ensures that the filter element will not fall off when transporting the gasifier.

[0015] 2. By setting up a wind box and mounting components, the surface of the wind box is equipped with a door. When it is necessary to inspect the fan, the door can be opened to inspect the fan. At the same time, the air outlet pipe and air inlet pipe connected to the fan are mainly connected together through the mounting components, which makes it more convenient to disassemble and repair the fan.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an improved gasification furnace ventilation fan, including a body 1, with a smoke pipe 2 connected through one side of the top of the body 1; a wind box 3 is fixedly installed on one side of the body 1, a fan 4 is fixedly installed inside the wind box 3, mounting parts 5 are fixedly connected to both sides of the fan 4, an outlet pipe 6 is fixedly installed on one side of the fan 4, a conveying pipe 7 is fixedly installed on the other side of the fan 4, and an inlet pipe 8 is fixedly installed on the side of the conveying pipe 7 away from the fan 4 and passing through the wind box 3; it also includes: limiting components 13 symmetrically arranged on the two sides of the inlet pipe 8 away from the conveying pipe 7; wherein, the limiting components 13 include connecting rods 1301 fixedly connected to the inlet pipe 8; wherein, support rods 1302 are symmetrically installed on one side of the connecting rods 1301, such as Figure 1-5As shown, by setting the filter element 10, dust in the air can be filtered, thereby reducing the amount of dust entering the fan 4 and reducing the damage to the bearings and impeller, thus extending the service life of the fan 4 to a certain extent. Simultaneously, by setting the limiting component 13, the installation and removal of the filter element 10 can be made more convenient, thereby improving the replacement efficiency of the filter element 10. Furthermore, the surface of the air box 3 is provided with a door, which can be opened to inspect the fan 4 when maintenance is required. The outlet pipe 6 and inlet pipe 8 connected to the fan 4 are mainly connected together by the mounting component 5, making disassembly and maintenance of the fan 4 more convenient. The support rod 1302 is located away from the connecting rod. A limiting box 1303 is fixedly connected to one side surface of 1301. A compression spring 1304 is fixedly installed inside the limiting box 1303. A stabilizing rod 1305 is fixedly connected to the bottom surface of the compression spring 1304. A pull rod 1306 is fixedly connected to the side surface of the stabilizing rod 1305 near the middle. A pulley 1307 is rotatably connected to the bottom surface of the stabilizing rod 1305. The stabilizing rod 1305 is connected through the limiting box 1303. The pulley 1307 is connected through the air inlet pipe 8. A baffle block 9 is provided inside the air inlet pipe 8. A filter element 10 is attached to one side surface of the baffle block 9. A slot 11 is symmetrically provided on the side surface of the filter element 10 near the baffle block 9. A locking rod 12 is engaged inside the slot 11. The side surface of the locking rod 12 away from the slot 11 is fixedly connected to the baffle block 9. Figure 3-5 As shown, during the installation of the filter element 10, after placing the filter element 10 inside the conveying pipe 7, so that the outer wall of the filter element 10 fits against the inside of the conveying pipe 7, the filter element 10 is pushed. As the filter element 10 moves inside the conveying pipe 7, it squeezes the pulley 1307. Simultaneously, the left side of the filter element 10 is inclined, which allows it to squeeze the pulley 1307. This causes the pulley 1307 to lift the stabilizing rod 1305, preventing the pulley 1307 from obstructing the filter element 10. After the filter element 10 moves to a certain position, the slot 11 engages with the locking rod 12. The filter is installed by engaging the locking mechanism. After the filter element 10 is installed, the pulley 1307 is positioned on the right side of the filter element 10, and the filter element 10 does not lift the pulley 1307. The stabilizing rod 1305 then descends under the action of the compression spring 1304. The descent of the stabilizing rod 1305 causes the pulley 1307 to descend as well, thus limiting and blocking the right side of the filter element 10. Since the right side of the filter element 10 is flat, it cannot squeeze the pulley 1307, preventing the filter element 10 from falling off during transport of the gasifier.

[0024] Working principle: Before using this improved gasification furnace ventilation fan, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, firstly, by setting the limiting component 13, when the filter element 10 needs to be replaced, the pull rod 1306 is pulled by a tool, causing the stabilizing rod 1305 to rise. The rise of the stabilizing rod 1305 causes the pulley 1307 to rise, and simultaneously, the rise of the stabilizing rod 1305 compresses the compression spring 1304, causing it to deform. After the pulley 1307 rises to a certain position and no longer obstructs the filter element 10, the filter element 10 is pulled by a tool, separating it from the blocking block 9, thus allowing for replacement. Simultaneously, when installing the filter element 10, after placing it inside the conveying pipe 7, ensuring the outer wall of the filter element 10 fits against the inside of the conveying pipe 7, the filter element 10 is pushed. As the filter element 10 moves within the conveying pipe 7, it will compress the pulley 1307. The filter element 10 is compressed, and its left side is inclined, which allows the pulley 1307 to be compressed. This causes the pulley 1307 to drive the stabilizing rod 1305 to rise, ensuring that the pulley 1307 does not obstruct the filter element 10. After the filter element 10 moves to a certain position, the slot 11 engages with the rod 12, thus completing the installation of the filter. After the filter element 10 is installed, the pulley 1307 is positioned on the right side of the filter element 10 and... After the filter element 10 does not lift the pulley 1307, the stabilizing rod 1305 descends under the action of the compression spring 1304. The descent of the stabilizing rod 1305 drives the pulley 1307 to descend, thereby allowing the pulley 1307 to limit and block the right side of the filter element 10. At the same time, the right side of the filter element 10 is flat, preventing it from squeezing the pulley 1307. This ensures that the filter element 10 will not fall off when transporting the gasifier.

[0025] Secondly, by setting up the air box 3 and the mounting part 5, the surface of the air box 3 is provided with a door. When it is necessary to inspect the fan 4, the door can be opened to inspect the fan 4. At the same time, the air outlet pipe 6 and the air inlet pipe 8 connected to the fan 4 are mainly connected together through the mounting part 5, which makes it more convenient to disassemble and repair the fan 4.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
