Description

Technical Field

[0001] The utility model relates to the technical field of silicon-manganese alloy smelting, in particular to a silicon-manganese alloy smelting fume dust removal device. Background Art

[0002] Silicon-manganese alloy smelting belongs to the field of metallurgical industry. The metallurgical industry refers to the conversion of ore into various metal products by means of mineral processing, smelting, casting, etc. There are two methods for smelting silicon-manganese alloy: direct smelting and indirect smelting. Flue gas will be generated during the smelting process, and the flue gas needs to be treated before discharge. The silicon-manganese alloy smelting flue gas dust removal equipment is used to separate and treat the impurity particles in the flue gas.

[0003] Among them, the publication number CN210543864U is a silicon-manganese alloy production dust removal system, which includes a flue gas cooling device, a dust removal device connected to the flue gas cooling device, and a dust cleaning device connected to the dust removal device. The air pipe of the utility model can rotate. When dust cleaning is required, the air extraction valve is closed and the air supply valve is opened to introduce air into the air pipe. At this time, the filter bag is expanded by the air, and the rotating motor drives the air pipe to rotate. The filter bag will hit the blocking rod, so that the dust on the filter bag falls off and is discharged from the dust outlet. In addition, the utility model is provided with a cooling device, which can first cool down the high-temperature flue gas for better dust removal.

[0004] The above-mentioned prior art utilizes air to expand the filter bag and controls its rotation to contact the baffle rod to clean the dust. This design not only makes it difficult for air to remain in the filter bag to expand the filter bag due to the mesh structure of the filter bag, but also the cleaning device cannot simultaneously clean the filter assembly while processing the smoke dust. The particulate matter remains on the filter assembly, which will affect the efficiency of flue gas treatment. In addition, the refrigerant delivery pipe is used to cool the air, and more air enters the cooling tank. The contact area between the air and the cooling material is small, and the cooling efficiency is low, and the flue gas cannot be cooled evenly and comprehensively. Therefore, we propose a silicon-manganese alloy smelting flue gas dust removal equipment to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the utility model is to provide a silicon-manganese alloy smelting flue gas dust removal device to solve the problem raised by the above-mentioned background technology that the filter component cannot be cleaned synchronously when the smoke is processed in the current market, and the particulate matter remains on the filter component, which will affect the treatment efficiency of the smoke, the contact area between the smoke and the cooling material is small, the cooling efficiency is low, and the smoke cannot be cooled evenly and comprehensively.

[0007] A water pump is installed at the upper right of the outer shell, a water outlet of the water pump is connected to a water inlet pipe, the water inlet pipe extends into the outer shell, and a drain pipe is connected to the lower right of the outer shell;

[0009] A filter plate is installed inside the left side of the outer shell, and the lower end of the filter plate is connected with a feed pipe.

[0010] Preferably, a spring is connected to the inside of the right side of the outer shell, and one end of the spring is connected to a knocking rod.

[0011] Preferably, the cooling tubes are of a bent structure, and are distributed in the outer shell at equal intervals.

[0012] Preferably, the fan blade is an arc-shaped structure, and the position of the fan blade corresponds to the lower port of the water inlet pipe.

[0013] Preferably, the lower end of the knocking rod is arranged in one-to-one correspondence with the position of the cooling tube, and the knocking rod forms an elastic structure with the outer shell through a spring.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The silicon-manganese alloy smelting flue gas dust removal equipment can use a cooling pipe to divert the flue gas, so that a small amount of flue gas flows slowly in the cooling pipe, so that the flue gas can be fully contacted with cold water, accelerate the conduction of flue gas heat, and quickly cool it down. The fan blades are driven by water flow to rotate, and the knocking rod is pushed to knock the cooling pipe, so that the moisture contained in the flue gas condenses into water droplets when the flue gas is cooled, and the water droplets are accelerated to fall and concentrate on the exhaust pipe, which is convenient for centralized cleaning;

[0017] (2) The silicon-manganese alloy smelting flue gas dust removal equipment uses the active rotating rod to rotate and control the driven rotating rod connected to the belt to rotate, and cooperates with the transmission of the bevel gear group to control the auxiliary rotating rod to drive the scraper to rotate, so as to scrape and clean the filter plate, so that the smoke and dust are concentrated into the discharge pipe along the inclined filter plate, which is convenient for centralized cleaning. This design can clean the filter plate synchronously while filtering the smoke, thereby ensuring the flow speed of the smoke. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The vacuum pump 2 is powered on, and the smoke is sucked into the air delivery pipe 3, and then diverted to the cooling pipe 4. There is less smoke in the cooling pipe 4.
