Technical Field
[0001] This utility model belongs to the field of waste gas collection technology, specifically relating to a high-temperature resistant and flame-retardant waste gas collection device. Background Technology
[0002] A boiler is an energy conversion device that requires fuel to convert energy, thereby outputting steam, high-temperature water, or organic heat carriers with a certain amount of heat energy. Boilers are widely used in power plants, industry, and daily life. Boilers commonly used in daily life usually use biofuels, firewood, or coal as fuel. After the fuel is completely burned, the exhaust gas needs to be collected and filtered.
[0003] Existing exhaust gas collection devices use a flexible curtain structure to block high temperatures or provide flame retardancy. However, these flexible curtains are usually fixed in place by hanging rings, which makes it inconvenient to disassemble and replace them over time. This can hinder the normal operation of the exhaust gas collection device and reduce its efficiency and speed. Utility Model Content
[0004] The purpose of this utility model is to provide a high-temperature resistant and flame-retardant exhaust gas collection device to solve the problem mentioned in the background art that the existing exhaust gas collection devices use a soft curtain structure to block high temperature or prevent flame retardancy. However, the existing soft curtains are generally fixed in the form of hanging rings during use. It is inconvenient to disassemble and replace the soft curtains after long-term use, which will hinder the normal operation of the exhaust gas collection device and reduce the working efficiency and speed.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an exhaust gas collection hood, a soft curtain, and a square support plate positioned below the exhaust gas collection hood. The support plate is equipped with an installation assembly. A square wedge-shaped groove is formed on the lower surface of the support plate. Several wedge-shaped plates are slidably installed within the wedge-shaped groove. A connecting rod is installed on the lower surface of each wedge-shaped plate. A U-shaped bracket is installed at the bottom end of the connecting rod. A spring is installed on one side of the inner wall of the bracket. A clamping plate is installed at one end of the spring. The top of the soft curtain is located between the corresponding clamping plate and the bracket. Two circular grooves are formed on both the front and rear sides of the support plate. These circular grooves communicate with the wedge-shaped grooves. A fixing rod is installed within each circular groove, and one end of the fixing rod extends into a fixing groove formed on the wedge-shaped plate.
[0006] By adopting the above scheme, a wedge plate, a clamping plate, a spring, and a fixing rod are set up. The wedge plate slides in the wedge groove, making it easy to open the soft curtain at any time. The spring provides elastic support for the clamping plate. The clamping plate fixes one end of the soft curtain to the bracket. The fixing rod fixes the wedge plate at the end, thus preventing the soft curtain from sliding randomly. This facilitates the disassembly and replacement of the soft curtain, and does not interfere with the normal operation of the exhaust gas collection device, thereby improving work efficiency and speed.

[0008] By adopting the above scheme, by setting up an installation plate and bolts, the installation plate is fixed to the support plate, and the bolts are further fixed to the support plate. Combined with the function of bolt thread installation, it is convenient to thread the support plate onto the exhaust gas collection cover, and it is also convenient to loosen the bolts to disassemble the support plate at any time later.
[0009] In a preferred embodiment, positioning pins are installed on both the left and right sides of the upper surface of the support plate, and positioning grooves are provided on both the left and right sides of the lower surface of the exhaust gas collection hood, which are arranged opposite to the positioning pins, with one end of the positioning pin extending into the positioning groove.
[0010] By adopting the above solution, the positioning pin is set, and the position of the support plate is accurately determined in the initial stage before the support plate is fixed, which facilitates the subsequent fixing of the support plate and makes the operation convenient.
[0011] In a preferred embodiment, two rotating columns are rotatably mounted on both the left and right sides of the exhaust gas collection hood. An L-shaped auxiliary plate is mounted on the rotating column, and the horizontal part of the auxiliary plate is located below the support plate and is in contact with the lower surface of the support plate.
[0012] The above scheme uses a rotating column and an auxiliary plate. The L-shaped auxiliary plate provides initial support for the support plate, facilitating its installation before fixation.

One end of the fixing rod extends through the through hole and a pull plate is installed on one end of the fixing rod. A spring is sleeved on the fixing rod, with its two ends respectively fixedly connected to the pull plate and the fixing plate.
[0014] By adopting the above scheme, a fixing plate, a second spring, and a pull plate are set up. The through hole on the fixing plate is used to support one end of the fixing rod, and the fixing rod is supported on the support plate. Combined with the function of the pull plate, it is convenient to operate the fixing rod. With the elasticity of the second spring, the fixing rod is prevented from falling off and the fixing rod is made more stable.
[0015] In a preferred embodiment, the inner top surface of the bracket has two sliding grooves, in which a sliding plate is slidably installed, and the sliding plate is fixedly connected to the clamping plate.
[0016] By adopting the above solution, a sliding plate is set up, and the sliding end of the sliding plate slides in the groove to limit and support the clamping plate, so that the clamping plate can move stably, improving the stability of the clamping plate and making the operation convenient.
[0017] In a preferred embodiment, a telescopic rod is provided inside the spring, the telescopic rod is installed inside the bracket, the telescopic shaft of the telescopic rod is fixedly connected to the clamping plate, and rubber pads are installed on one side of the clamping plate and one side of the inner wall of the bracket.
[0018] By adopting the above solution, by setting up a telescopic rod and a rubber pad, the telescopic rod's elasticity is used to fill the interior of spring one, thereby improving the fullness of spring one's interior. This allows spring one to stably support the clamping plate, and also prevents spring one from tilting to the side, thus extending the service life of spring one. The rubber pad is used to protect the soft curtain, preventing the edges of the clamping plate from damaging the soft curtain, thereby protecting the soft curtain.
[0019] In a preferred embodiment, an L-shaped operating rod is slidably mounted on the bracket, and one end of the operating rod is fixedly connected to the clamping plate.
[0020] By adopting the above solution, and by setting up an operating lever, the L-shaped position of the operating lever makes it easy for users to pull the operating lever, which can easily drive the clamping plate to move. The operation is convenient and the structure is simple, bringing great convenience to the users.
