Description

Technical Field

[0001] The invention relates to the technical field of coal gas desulfurization, and in particular to a cleaning dosing device. Background Art

[0002] In recent years, my country's steel industry has accelerated its transformation and upgrading, actively promoted the green and sustainable development of the industry, and focused on promoting the implementation of ultra-low emissions in the steel industry. More and more companies have adopted the method of desulfurization at the source of coal gas to further reduce the sulfur dioxide content in exhaust gas. Biological desulfurization technology is currently a rapidly developing source desulfurization technology.

[0003] The catalyst used in biological desulfurization technology is of special nature. It is not a single solid or liquid state, but a moist, sticky powdered solid and liquid mixture. It is packaged in plastic bags for daily storage and transportation, and needs to be prepared into a solution when used. Due to the influence of the catalyst's own properties, direct unpacking and use will inevitably cause the catalyst to splash out, contaminate the ground, wall and operator's clothing, etc. Although some of the splashed catalyst can be recycled by flushing and collection, it will still cause different degrees of waste, and at the same time make the operation process more complicated and cumbersome, and greatly increase the time and labor costs. Therefore, those skilled in the art provide a cleaning and dosing device to solve the problems raised in the above background technology. Summary of the invention

The pretreatment box is arranged on the outer side of the top surface of the medicine tank, and the pretreatment box is connected to the medicine tank through a crank connecting rod mechanism; the medicine dosing box is installed inside the medicine tank, and the medicine dosing box is connected to the medicine tank through a guide rail.

[0006] As a further solution of the present invention, a shaft is installed inside the medicine tank, the bottom surface of the shaft is connected to the blades, the top surface of the shaft is connected to the motor, and the motor is fixed in the middle of the outer top surface of the medicine tank.

[0007] As a further solution of the present invention, a drug adding port is provided on one side of the top surface of the reagent tank, and the drug adding port is consistent in shape and size with the top of the pretreatment box.

[0008] As a further solution of the present invention, the medicine adding box body structure is in the shape of a filter mesh.

[0009] As a further solution of the present invention, the guide rail is arranged inside the medicine tank and installed on both sides of the medicine adding port, and the medicine adding box can move up and down along the guide rail.

[0010] As a further solution of the present invention, the top of the pretreatment box is provided with a movable cover, and the movable cover can be rotated to open.

[0011] As a further solution of the present invention, a blade is installed on the bottom plate of the pre-treatment box.

[0012] As a further solution of the present invention, one end of the crank-connecting rod mechanism is connected to the reagent tank, and the other end is connected to the pretreatment box. The pretreatment box can be inverted on the drug adding port under the action of the crank-connecting rod mechanism.

[0013] As a further solution of the present invention, the catalyst is stacked outside the pretreatment box.

[0014] As a further solution of the present invention, a mechanical gripper is installed at the end of the mechanical arm and is installed above the pretreatment box.

[0015] The beneficial effects of the present invention are: 1. The catalyst is grabbed by the mechanical gripper on the robotic arm and added to the dosing box. Then the catalyst dosing box moves down along the guide rail and immerses into the original solution in the reagent tank to realize the catalyst dosing operation, making the entire dosing process simple and convenient, saving overall time and reducing labor costs.

[0016] 2.
