Calcium spraying equipment in furnaces is widely used in high-temperature furnaces in the steel, cement, glass and other industries. It is an important protective equipment that helps to improve production efficiency and extend the service life of equipment.

[0003] The boiler calcium carbonate system uses an electric air lock as the conveying equipment and a Roots blower as the main power source. It is equipped with a limestone storage, unloading system and conveying pipeline. The limestone powder enters the top of the silo from the ball valve and falls into the limestone powder silo through the terminal box. The compressed air is led to the silo top dust collector through the pressure reducing valve and the air source treatment two-piece for backblowing air source. When the gasification is completed, the variable frequency air lock rotary unloading valve, pneumatic return air butterfly valve and pneumatic gate valve are opened to unload, and finally the pipeline is cleaned.

[0004] Most of the in-furnace calcium spraying equipment are equipped with an exhaust filter on the top of the powder bin, and most of them use a pulse bag dust collector to filter the ash gas in the ash bin. However, due to the frequent use of the device, the pulse bag will gradually wear out during use, resulting in a decrease in the sealing performance of the pulse bag, affecting the pulse effect. Most of the existing dust bags and buckles are threadedly connected, which makes disassembly more cumbersome and inconvenient to replace the dust bags. Therefore, an in-furnace calcium spraying equipment is proposed to solve the problems raised by the background technology. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown, the utility model provides a furnace calcium spraying equipment, including a dust removal bag 1 and a dust removal device 15, the dust removal bag 1 is fixedly connected to a metal support sheet 2 inside, the top circumferential array of the metal support sheet 2 is provided with a first inclined block 3, an outer cylinder 4 is placed on the top of the dust removal device 15, the inner circumferential array of the outer cylinder 4 is movably connected to a second inclined block 5, the top of the second inclined block 5 is fixedly connected to a round rod 6, the opposite sides of the two second inclined blocks 5 are fixedly connected to springs 7 fixedly connected to the outer cylinder 4, the inner part of the outer cylinder 4 is movably connected to a turntable 8, the top circumferential array of the turntable 8 is provided with a guide groove 9, one side of the turntable 8 is fixedly connected to a support block 10, the inner part of the support block 10 is fixedly connected to a rotating shaft 11, the outer part of the support block 10 is movably connected to an arc-shaped rotating rod 12, and a gasket 14 is provided at the bottom of the outer cylinder 4.

[0024] When the arc-shaped rotating rod 12 drives the supporting block 10 to rotate, the supporting block 10 drives the turntable 8 to rotate clockwise, and then drives the two round rods 6 and the two second inclined blocks 5 thereunder to move in opposite directions through the guide grooves 9, and then the second inclined blocks 5 are released from the first inclined blocks 3, thereby facilitating the operator to disassemble and replace the metal supporting sheet 2.

[0025] like Figures 1 to 4 As shown, the top of the first inclined block 3 is in the shape of an inclined surface, and the opposite side of the two second inclined blocks 5 is in the shape of an inclined surface. When the first inclined block 3 moves upward, it abuts against the inclined surface of the second inclined block 5. A slot is provided on the opposite side of the two first inclined blocks 3. One end of the second inclined block 5 is initially located inside the slot. The turntable 8 is in the shape of an arc, and the top of the round rod 6 is movably connected to the inside of the guide groove 9. The gasket 14 is made of rubber material.

[0026] The gasket 14 is made of rubber material, and its function is that since there is a large contact area between the gasket 14 and the dust removal device 15, the friction between the two is enhanced, thereby improving the grip and anti-slip performance of the outer cylinder 4, and thus reducing the possibility of shaking of the outer cylinder 4; when the first inclined block 3 moves upward, it abuts against the inclined surface of the second inclined block 5, which is used to squeeze the two second inclined blocks 5 to move in opposite directions. When the gasket 14 abuts against the top of the dust removal device 15, the second inclined block 5 is reset under the action of the elastic force of the spring 7 and is stuck into the inside of the first inclined block 3, thereby fixing the position of the dust removal bag 1.

[0027] like Figures 1 to 5 As shown, the spring 7 is used to squeeze the second inclined block 5 and keep it moving toward the first inclined block 3. The interior of the outer cylinder 4 is provided with slide grooves 13 located on both sides of the second inclined block 5, which are used to limit the second inclined block 5 in the vertical direction when moving. The support block 10 penetrates the outer wall of the outer cylinder 4 and extends to its outside. The arc-shaped rotating rod 12 rotates around the rotating shaft 11 as the axis. The arc-shaped rotating rod 12 is initially located inside the outer cylinder 4. After the arc-shaped rotating rod 12 rotates, it abuts against one side of the support block 10 and drives it to rotate. The rotation of the support block 10 causes the turntable 8 to rotate clockwise and drives the two round rods 6 to move in the opposite direction through the guide groove 9. The round rod 6 drives the second inclined block 5 to move and release the clamping connection with the first inclined block 3.

[0028] The second inclined block 5 is squeezed by the spring 7 to keep the tendency to move toward the first inclined block 3. Its function is that when the first inclined block 3 moves downward and leaves the interior of the outer tube 4, the second inclined block 5 is reset under the action of the elastic force of the spring 7, thereby facilitating the operator's next use.

[0029] The working principle and use process of the utility model are as follows: the operator pulls one end of the arc-shaped rotating rod 12, and then the arc-shaped rotating rod 12 rotates with the rotating shaft 11 as the axis. When the arc-shaped rotating rod 12 rotates ninety degrees, the arc-shaped rotating rod 12 abuts against the inner wall of one side of the support block 10, and then the arc-shaped rotating rod 12 continues to rotate, thereby driving the turntable 8 to rotate clockwise through the support block 10, and then driving the two round rods 6 to move in opposite directions through the guide groove 9. When the round rod 6 moves, it drives the second inclined block 5 to move in the same direction, so that the second inclined block 5 is released from the first inclined block 3, and then the dust removal bag 1 is pulled downward, so that the first inclined block 3 is released from the outer cylinder 4, and the operation is completed.

[0030] The powder storage system mainly consists of dust removal on the top of the storage, exhaust, material level indication, powder storage gasification air system and storage bottom unloading system. After the air source pressure is normal, the dust collector on the top of the storage must be put into operation first. The operation of the dust collector on the top of the storage can only be stopped when all tank trucks stop transporting limestone to the powder storage or the dust collector fails.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
