Description

Technical Field

[0001] The utility model relates to the technical field of iron removal from limestone powder, in particular to an iron removal device for production and processing of desulfurized limestone powder. Background Art

[0002] At present, lime is an air-hardening inorganic cementitious material with calcium oxide as the main component. Lime is a product with high calcium carbonate content such as limestone, dolomite, chalk, and shells, which is calcined at 900-1100℃. Lime is the earliest cementitious material used by humans. Lime is widely used in civil engineering and can also be used in medicine in my country.

[0003] Among them, lime or limestone desulfurization uses lime or limestone slurry to absorb sulfur dioxide in flue gas in an absorption tower to obtain a mixture of calcium sulfite and calcium sulfate, which is then sent to an oxidation tower and oxidized by air. The resulting calcium sulfate slurry is centrifuged and washed to obtain finished calcium sulfate. The advantage of this method is that the absorbent is cheap and easy to obtain, so it is widely used in industry. The disadvantage is that the equipment is prone to scaling and clogging.

[0004] Most of the limestone powder desulfurization equipment used on the market will separate iron elements during the desulfurization process, and the iron elements remain inside the equipment and are difficult to clean. Therefore, it is necessary to design a new technical solution to solve the problem, which can efficiently and quickly remove the iron powder in the limestone powder. Utility Model Content

[0005] The utility model aims to provide an iron removal device for producing and processing desulfurized limestone powder, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deironing device for the production and processing of desulfurized limestone powder, comprising a first conveying seat, both sides of the first conveying seat are rotatably mounted with rotating shafts, both sides of two groups of the rotating shafts are fixedly mounted with transmission rollers, and the outer sides of multiple groups of the transmission rollers are transmission-mounted with transmission belts, both sides of the first conveying seat are fixedly mounted with multiple groups of equidistantly distributed mounting frames, and the middle parts of the multiple groups of mounting frames are fixedly mounted with magnetic plates, and the magnetic plates correspond to the transmission belts, and a uniform material guiding mechanism is installed on one side of the top of the first conveying seat;

[0007] The uniform material guiding mechanism includes a second conveying seat installed on one side of the top of the first conveying seat, a fixed seat fixedly installed on one side of the top of the second conveying seat, a flattening roller rotatably installed inside the fixed seat, and a guide seat obliquely installed at one end of the second conveying seat, the other end of the guide seat corresponds to the first conveying seat.

[0008] As an optional solution of the technical solution of the present application, a guide plate is obliquely installed on one side of the first conveying seat, and a leakage port is opened on the inner side of the guide plate. The leakage port corresponds to the transmission belt, and the adsorbed iron powder can pass through the leakage port.

[0009] As an optional solution of the technical solution of the present application, a motor is fixedly installed on one side of the fixed seat, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on one end of the flattening roller, which can drive the flattening roller to rotate.

[0010] As an optional solution of the technical solution of the present application, piston cylinders are fixedly installed in the middle of both sides of the first conveying seat, and piston columns are movably installed in the two groups of piston cylinders, so that the cleaning plate can be installed.

[0011] As an optional solution of the technical solution of the present application, a cleaning plate is fixedly installed at the other end of the two groups of piston rods, and the cleaning plate is in contact with the outer wall of the transmission belt to clean the surface of the transmission belt.

[0012] As an optional solution of the technical solution of the present application, the outer walls of the two groups of piston columns are sleeved with springs, and the two sides of the two groups of springs are respectively fixed to the piston cylinder and the outer wall of the piston column, and can be supported by a cleaning plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application is to transmit the power by driving the transmission belt outside the transmission roller, so that the limestone powder inside the first conveyor seat can be continuously conveyed on the transmission belt. In conjunction with the magnetic plate installed inside the first conveyor seat, the iron powder contained in the limestone powder can be adsorbed and attached to the transmission belt. After the iron powder on the transmission belt is separated from the magnetic plate, it will automatically detach and complete the iron powder removal. At the same time, before the limestone powder is introduced into the first conveyor seat, it will first be introduced into the second conveyor seat, and the motor will be driven to drive the flattening roller and the second transmission belt to rotate in the opposite direction. The amount of limestone powder introduced into the first conveyor seat can be well controlled to ensure that the limestone powder is evenly laid on the surface of the transmission belt, so that the magnetic plate can fully adsorb the iron powder.

[0015] 2. The technical solution of the present application is that piston columns are movably installed in two groups of piston cylinders, and cleaning plates are fixedly installed at the other ends of the two groups of piston columns. When the iron powder on the conveyor belt is transmitted to the bottom of the first conveyor seat, it will slowly move away from the magnetic plate.

At the same time, with the cleaning plates installed at the bottom of the two groups of piston columns, the iron powder adhering to the transmission belt can be efficiently cleaned, which is convenient for the secondary cleaning of the iron powder on the transmission belt.
