Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a spraying device for calcium hydroxide desulfurizing agent. Background Technology

[0002] The calcium hydroxide desulfurizing agent injection device is a piece of equipment used to inject calcium hydroxide desulfurizing agent into flue gas. It is mainly used for flue gas desulfurization treatment. The device injects calcium hydroxide desulfurizing agent evenly into the flue gas through the injection system, so that it reacts with sulfur dioxide in the flue gas to generate calcium sulfate, thereby achieving the purpose of desulfurization. The fixed bed reactor adopts a static data tower plate structure. The desulfurizing agent is replenished in the reactor in a fixed manner. Flue gas desulfurization is carried out when the flue gas passes through the material layer.

[0003] For example, the desulfurizing agent injection device for flue gas desulfurization disclosed in authorization announcement number CN117619133B includes a mounting base; an injection mechanism, which is mounted on the mounting base and includes a pneumatic conveying fan mounted on the mounting base, a connecting pipe connected to the pneumatic conveying fan via a flange mounted on the mounting base, an injector connected to the connecting pipe via a flange mounted on the mounting base, and a spray gun connected to the injector via an air outlet pipe; and a storage mechanism.

[0004] Although it achieves the goal of ensuring the stability of the connection between the top pipe and the bottom pipe, when the two are connected, the insert rod is inserted into the hole on the fixed plate to increase the stability of the connection and avoid the leakage of calcium oxide caused by shaking during material feeding. When the pressure rod rotates, it can knock the contact plate on the top of the rotary discharge valve at regular intervals, thereby shaking the rotary discharge valve and avoiding the blockage of calcium oxide at the rotary discharge valve, which is conducive to material feeding and fixing the insulation shell. At this time, the insulation shell is in close contact with the outer wall of the calcium oxide buffer chamber, which achieves the insulation of calcium oxide, ensures its activity, and is conducive to the treatment of sulfides.

[0005] However, this does not solve the problem that existing spraying devices of this type are generally not convenient to move to the work area for lifting and feeding, which affects the work intensity of manual high-level feeding, is not convenient for multi-position and multi-group spraying, is not convenient for spraying at a certain angle, which affects the spraying range, and is not convenient for quickly and efficiently spraying out the desulfurizing agent, thus affecting the spraying efficiency of the spraying device. Utility Model Content

[0006] The purpose of this invention is to provide a spraying device for calcium hydroxide desulfurizing agent, in order to solve the problems mentioned in the background art, such as the inconvenience of moving the spraying device to the working area for lifting and feeding, which affects the work intensity of manual high-level feeding, the inconvenience of multi-position and multi-group spraying, the inconvenience of rotating it at a certain angle for spraying, which affects the spraying range, and the inconvenience of quickly and efficiently spraying out the desulfurizing agent, which affects the spraying efficiency of the spraying device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for calcium hydroxide desulfurizing agent, comprising a moving plate and a hopper. The hopper is installed inside the moving plate and extends through the moving plate to its outside. A track is symmetrically arranged outside the hopper, and a moving trolley is arranged outside the track. A hopper is installed inside the moving trolley. A disc is installed at the bottom of the hopper, and four sets of L-shaped plates with equal spacing are installed on the top side wall of the disc. A support shaft is symmetrically and movably installed at the top of the moving plate. Electric wheels are fitted at both ends of the support shaft and are slidably connected to the track.

A second feed pipe is installed on the upper surface of the conveying cylinder and contacts the hopper. A discharge pipe is installed on the lower surface of the conveying cylinder, and a stepper motor is installed on the side wall of the conveying cylinder.

[0008] Preferably, the output end of the stepper motor is equipped with a screw rod, which extends into the interior of the conveying cylinder and is movably connected thereto.

[0009] Preferably, the surface of the silo is equipped with four sets of material pumps at equal intervals, the output end of each material pump is equipped with a flexible hose, and a servo motor is installed on the side wall of the L-shaped plate.

[0010] Preferably, the output ends of the servo motors are all equipped with rotating shafts, and the surfaces of the L-shaped plates are all equipped with first support plates.

[0011] Preferably, a second support plate is installed on the side of the L-shaped plate away from the first support plate, and the rotating shaft extends through the first support plate and the second support plate to their outside.

[0012] Preferably, the surface of each rotating shaft is fitted with a flip plate, and the surface of each flip plate is fitted with a hollow box.

[0013] Preferably, a pneumatic conveying fan is installed on the side wall of the hollow box, and a first feed pipe is installed on the side of the hollow box away from the pneumatic conveying fan.

[0014] Preferably, spray guns are installed on the side of the hollow box away from the first feed pipe, and the hoses are all connected to the first feed pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the spraying device not only realizes the convenient movement of the spraying device to the working area for lifting and feeding, reducing the labor intensity of manual high-level feeding, but also facilitates convenient multi-position and multi-group spraying, facilitates spraying at a certain angle, increases the spraying range, and facilitates the rapid and efficient spraying of desulfurizing agent, thus improving the spraying efficiency of the spraying device.

[0016] When using the calcium hydroxide desulfurizing agent spraying device, the mobile trolley 4 is moved to the feeding area, and the desulfurizing agent is poured into the hopper 20. It then falls into the silo 2 through the hopper 20 and the second feed pipe 22. The electric wheel 7 drives the support shaft 8 to slide inside the track 3.

The stepper motor 23 drives the screw rod 24 to rotate. The screw rod 24 drives the desulfurizing agent inside the hopper 20 and the second feed pipe 22 to move upward and convey it until it moves to the surface of the discharge pipe 25.

This facilitates convenient movement to the working area for feeding, realizes convenient movement of the spraying device to the working area for lifting feeding, reduces the labor intensity of manual high-level feeding, and improves the convenience of feeding the spraying device.

[0017] The material pump extracts the desulfurizing agent from the silo and transports it to the interior of the hollow box through a hose and the first feed pipe. The pneumatic conveying fan blows the desulfurizing agent from the hollow box out through the spray gun. The servo motor drives the rotating shaft to rotate, which in turn drives the tilting plate, the pneumatic conveying fan, the hollow box, the first feed pipe, and the spray gun to tilt and spray. This facilitates convenient tilting at a certain angle for spraying, enabling convenient multi-position and multi-group spraying of the spraying device. It also increases the spraying range, facilitates rapid and efficient spraying of the desulfurizing agent, and improves the spraying efficiency of the spraying device. Attached Figure Description
