Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] The specific implementation of this embodiment is as follows.

[0025] Such as figure 2 As shown, two anti-blocking pressure-taking boxes 1 are manufactured. Weld the electrostatic sedimentation orifice plate 101 on the bracket 102, then weld the bracket 102 on the mouth of the pressure equalization chamber cover 104, insert the pressure taking hole tube 103 into the inside of the pressure equalization chamber cover 104, and weld it to the top of the pressure equalization chamber cover 104 .

[0026] Select two positions on the furnace cover of the submerged arc furnace to open two round holes, and weld the anti-blocking pressure-taking box 1 at the opening positions.

[0027] Press as figure 1 As shown in the connection relationship, use conduit 5 to connect anti-blocking pressure box 1, solenoid valve group 2, pressure transmitter 3, nitrogen tank 4, and ...

Abstract

The invention discloses an anti-blocking furnace pressure tapping device of a closed submerged arc furnace. The anti-blocking furnace pressure tapping device comprises an anti-blocking pressure tapping box (1), an electromagnetic valve group (2) and a pressure transmitter (3), the anti-blocking pressure tapping box (1) is composed of an electrostatic precipitation pore plate (101), a support (102), a pressure tapping pore pipe (103) and a pressure equalizing cavity cover (104). The electrostatic precipitation pore plate (101) is welded on the support (102); the support (102) is welded at a cover opening of the pressure equalizing cavity cover (104); the pressure tapping pore pipe (103) is inserted into the pressure equalizing cavity cover (104) and is welded with the top of the pressure equalizing cavity cover (104); and the anti-blocking pressure tapping box (1) is connected with the electromagnetic valve group (2) through a guide pipe (5), the electromagnetic valve group (2) is connected with the pressure transmitter (3) through a guide pipe (5), the electromagnetic valve group (2) is connected with the control cabinet (6) through a wire, and the anti-blocking pressure tapping box (1) is welded on a furnace cover of the closed submerged arc furnace. The submerged arc furnace pressure tapping device has a dust adsorption and sedimentation function, solves the problem of blockage of a submerged arc furnace pressure measuring pressure tapping pipe, has a N2 cleaning function, and can ensure continuous measurement of furnace pressure.

Description

technical field [0001] The invention relates to an anti-blocking type closed submerged arc furnace pressure taking device. The submerged arc furnace includes a ferroalloy electric furnace, a calcium carbide furnace, etc., and is used as a pressure taking device for measuring gas pressure in a closed submerged arc furnace in the metallurgical industry. Background technique [0002] Submerged Arc Furnace is a kind of industrial electric furnace with continuous operation. It is mainly used for reducing and smelting ore, producing ferro-silicon, ferro-manganese, ferro-chromium, silicon-manganese alloy and other ferroalloys. As raw materials for smelting alloy steel, it can also produce chemical raw materials such as calcium carbide. Submerged arc furnace is a typical industry with high energy consumption and high pollution. According to the national industrial structure adjustment policy of "turning off the small and increasing the large", the submerged arc furnace smelting techn...
