Description

Technical Field

[0001] The utility model belongs to the technical field of refractory material production, and particularly relates to a purification device for refractory material production. Background Art

[0002] Refractory materials are inorganic non-metallic materials used in high-temperature environments. They are mainly used to withstand chemical erosion and physical wear inside high-temperature thermal equipment. They play a key role in the lining of high-temperature industrial furnaces such as iron-making blast furnaces, steel-making converters, glass melting furnaces, ceramic firing kilns, and other high-temperature processing equipment. According to different chemical compositions and properties, refractory materials can be divided into acidic, neutral, alkaline and other types, and can also be subdivided into ordinary refractory materials and advanced refractory materials according to refractoriness. In the production process of refractory materials, a certain amount of waste gas will be generated. Therefore, in order to reduce environmental pollution and comply with environmental protection regulations, a purification device for refractory production is required.

[0003] Existing purification devices for refractory material production purify the waste gas generated during refractory material production by spraying waste gas treatment liquid through a fixed spray head. The fixed spray head cannot achieve uniform and sufficient spray coverage of the waste gas, thereby affecting the mass transfer efficiency between gas and liquid and reducing the absorption and removal effect of pollutants in the waste gas. Utility Model Content

[0004] In view of this, the utility model aims to provide a purification device for refractory material production to address the deficiencies of the prior art. The angle-adjustable liquid spray head can achieve comprehensive, no-dead-angle spray purification of waste gas generated during refractory material production, thereby effectively improving the purification efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a purification device for refractory material production, including a mounting frame, a purification box is arranged inside the mounting frame, an air outlet pipe is arranged at the air outlet opened at the upper end of the purification box, an air inlet pipe is arranged at the air inlet opened at the lower right end of the purification box, a liquid outlet pipe is arranged at the liquid outlet opened at the lower end of the purification box, a solenoid valve is connected in series in the middle of the liquid outlet pipe, an observation window is arranged in the mounting port opened on the front side of the purification box, a spray purification mechanism is arranged at the lower end of the purification box, a filtering mechanism is arranged at the upper end of the purification box, the spray purification mechanism is slidably arranged on four sliding blocks at the lower end of the purification box, and two adjacent sliding blocks at the front and rear are rotatably connected by rotating shafts respectively. There are cavity plates, and liquid spray heads are arranged in the liquid spray ports evenly distributed at the lower ends of the two cavity plates. Liquid inlet pipes are respectively arranged in the liquid inlets opened at the upper ends of the two cavity plates. Avoidance ports corresponding to the positions of the liquid inlet pipes are opened on the left and right sides of the purification box, and gears are arranged on the rear sides of the outer arc surfaces of the two rotating shafts. A rack plate is arranged inside the purification box, and two gears are meshed and connected with a rack plate. A bidirectional screw is arranged for internal rotation of the purification box, and the two cavity plates are respectively threadedly connected to the corresponding ends of the bidirectional screw. An electric drive unit for driving the bidirectional screw to rotate is arranged on the right side of the purification box, and the electric drive unit includes a motor arranged on the right side of the purification box, and the output shaft of the motor is connected to the right end of the bidirectional screw through a coupling.

[0006] As a further improvement of the present invention, the filtering mechanism includes an activated carbon adsorption plate slidably arranged on the upper end of the purification box, a filter screen located at the lower end of the activated carbon adsorption plate is slidably arranged inside the purification box, a limiting component is arranged on the right side of the purification box, the limiting component includes two spring pieces 1 rotatably arranged on the right side of the purification box, the two spring pieces 1 are installed in cooperation with an activated carbon adsorption plate, and two spring pieces 2 are rotatably arranged on the right side of the purification box, the two spring pieces 2 are installed in cooperation with a filter screen.

[0007] As a further improvement of the utility model, a control panel is provided on the front side of the purification box, and the motor and the solenoid valve are electrically connected to the control panel.

[0008] As a further improvement of the utility model, a support plate is welded and fixed to the lower end of the mounting frame, and four mounting holes are opened inside the support plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, by connecting the liquid inlet pipe to the external waste gas treatment liquid delivery pipe, the waste gas treatment liquid enters the interior of the cavity plate and is sprayed out through multiple spray heads, and then the air inlet pipe is connected to the waste gas pipe of the refractory material production device, and the motor is turned on to run, and the output shaft rotates to drive the bidirectional screw to rotate, and then drives the spray heads on the cavity plates on both sides to move back and forth to spray the waste. At the same time, the gear on the rotating shaft is affected by the meshing relationship of the rack plate and starts to rotate, thereby driving the spray heads on the cavity plates on both sides to rotate slightly back and forth to spray the waste gas. The pollutants in the waste gas come into contact and absorption with the dissolved substances in the waste gas treatment liquid, and the pollutants are dissolved, adsorbed or chemically converted into low-pollution waste gas. The spray head with adjustable angle can realize comprehensive and dead-angle spray purification of the waste gas generated during the production of refractory materials, effectively improving the purification efficiency.

[0011] Secondly, low-pollution exhaust gas will rise upward, and then be further filtered by the filter net and activated carbon adsorption plate in turn. The filtered exhaust gas is purified into pollution-free gas and discharged from the exhaust pipe. When it is necessary to clean or replace the activated carbon adsorption plate and the filter net, the rotating spring piece 1 and the spring piece 2 are sequentially turned to make them leave the surface of the activated carbon adsorption plate and the filter net, and then the personnel take out the activated carbon adsorption plate and the filter net for cleaning and replacement, and then insert the cleaned or replaced activated carbon adsorption plate and the filter net into the interior of the purification box, and sequentially turn the rotating spring piece 1 and the spring piece 2 to make them close to the surface of the activated carbon adsorption plate and the filter net to limit them, and the activated carbon adsorption plate and the filter net can be quickly disassembled for cleaning and replacement.

[0012] Third, the purification situation inside the purification box can be observed through the observation window, so that personnel can understand the internal exhaust gas purification situation in time.

[0013] Fourthly, the purification device is supported by the support plate, and the mounting holes are convenient for personnel to fix it, thereby preventing the purification device from moving during operation, and making the operation of the purification device more stable.
