Description
Technical Field
The utility model relates to a cooling water jacket of a distributor, and belongs to the field of distributor equipment.
Background
The distributing device is a core component of blast furnace charging equipment, and is used for uniformly distributing raw materials into the blast furnace through the rotation and tilting of the chute, and is a link device for the up-and-down opening of the blast furnace ironmaking. The distributor is located at the furnace end, the lower end is connected with the blast furnace body, and waste heat and waste gas in pig iron smelting are discharged into the riser through the channel of the distributor. As shown in figure 1, the bottom of the distributor is in direct contact with flame, smoke and air flow of the hearth, so a water cooling disc 11 is arranged at the bottom layer of the distributor, a mosquito-repellent incense type water channel 12 is arranged on the top surface of the water cooling disc, a spiral water channel similar to the mosquito-repellent incense type water channel is arranged at the lower part of the water cooling disc, and a refractory material layer 13 is arranged at the lower part of the water cooling disc, so that heat of the hearth cannot radiate to the inner cavity of the distributor. The channel of the distributor for conveying the blast furnace off-gas is called a central throat 14, and the connecting sleeve for rotating around the central throat 14 and driving the chute 16 to distribute the blast furnace off-gas to the hearth is called a rotating sleeve 15. The water cooling disc 11, the central throat 14 and the rotary sleeve 15 are three independent parts, and the rotary sleeve 15 and the chute 16 synchronously move and are combined into a whole in the production process.
A gap exists between the rotary sleeve 15 and the central throat 14, so that a heat source can be radiated to peripheral components of the rotary sleeve, and mechanical transmission components cannot accept high-temperature roasting, otherwise, faults can occur, and normal operation is affected. In order to prevent the temperature rise of the inner cavity of the distributor from affecting the operation of the mechanical transmission part and the failure of the sealing element, the traditional method is to blow high-pressure nitrogen into the inner cavity of the distributor and cool the rotary sleeve by running water.
A water cooling device for a distributor as claimed in application number 201510938569.7, wherein the water inlet passage penetrates the distributor housing and functions to guide the low-temperature external cooling water to the inside. The water outlet passage passes through the distributor housing and functions to guide the internal cooling water, which is involved in the circulation and has a high temperature, to the outside. The water inlet tank and the water outlet tank are annular cavities taking the central line of the blast furnace as a rotation center, the upper partition plates are separated, the water outlet tank is positioned outside the water inlet tank, namely the water outlet tank surrounds the water inlet tank, so that heat is blocked through the high liquid level of the water inlet tank, and the rotating body is prevented from long-term high-temperature deformation resistance. Meanwhile, a nitrogen channel is arranged on the distributor shell to introduce nitrogen with the pressure higher than that of gas in the furnace into the distributor, so that the effects of forming a high-pressure area to block dust-containing gas and assisting in cooling are achieved. However, the method ensures that the cooling water flows out from the water outlet channel slowly, the heat taken away by the water flow is less, the cooling strength is low, and dead angles which are difficult to flow out exist at the same time; and the nitrogen consumption is large, thus increasing the production cost.
The furnace top chute distributor of the closed water-cooled blast furnace is provided with a water-cooled jacket arranged on the outer circular surface of the throat of the distributor, as in the application number 03269812.7; the water cooling jacket and the water cooling disc are of a water inlet and outlet closed structure; an annular water distribution cavity is arranged at the bottom of the inner cavity of the water cooling jacket; the upper part of the water distribution cavity is provided with a water distribution baffle plate with uniformly distributed water outlets, the busbar direction of the inner cavity of the water cooling jacket is provided with a water inlet channel, the upper end of the water inlet channel is communicated with a water inlet pipe of the water cooling jacket, the lower end of the water inlet channel is communicated with the water distribution cavity, and the water cooling jacket is provided with a water inlet and a water outlet. The cooling water flow direction of the throat pipe part adopts a circulation mode of downward inlet and upward outlet, namely, the cooling water flows into the annular water distribution cavity at the bottom of the jacket along the independent descending water inlet channel after entering the water cavity of the water cooling jacket, overflows through the overflow holes on the water distribution partition plate at the upper edge of the water distribution cavity, flows upwards and finally flows out through the water outlet of the water cooling jacket. However, the structure is complex, the cooling water flows out slowly from the water outlet channel, the heat taken away by the water flow is less, the cooling strength is low, and dead angles which are not easy to flow out are also formed.
