TECHNICAL FIELD
[0001] The utility model relates to a steelmaking vaporization system technical field especially a prevent stifled device for the low pressure pump water suction port of the deaerator in the steelmaking vaporization system. BACKGROUND
[0002] The steelmaking vaporization system is an important component in the converter steelmaking, generally including a steam pocket, a deaerator, a vaporization cooling system, a heat accumulator, a pump set and the like. The pump set pumps water to the deaerator, and after treatment by the deaerator, part of the water enters the steam pocket, which is pumped by a high pressure pump to each part of the smoke hood for circulation, recovering steam and water, and recycling; the other part is pumped by a low pressure pump from the bottom of the deaerator to the movable smoke hood for cooling. The vaporization system is an important process link for ensuring the converter steelmaking.
[0003] The deaerator is internally composed of many steel structures, including steel plates, angle steels and the like. The steel structures inside the deaerator often fall off. Since the deaerator is connected to the water inlet pipe of the low pressure pump at the bottom, the water suction port at the top of the water inlet pipe is easily covered by the fallen steel structures, affecting water suction. Insufficient or no water suction directly leads to the failure of the low pressure pump to cool the smoke hood, causing unplanned shutdown of the entire steelmaking vaporization system, and reducing the stability and functionality of the equipment operation. UTILITY MODEL CONTENT
[0004] The utility model wants to solve the problem of providing a deaerator low pressure pump water suction port anti-blocking device to solve the problem of the water suction port at the bottom of the existing deaerator being easily blocked, affecting the water suction of the low pressure pump.
[0005] In order to solve the above problems, the technical scheme of the utility model is: the deaerator low pressure pump water suction port anti-blocking device includes a cross-shaped steel structure provided on the suction port of the low pressure pump water inlet pipe. The cross-shaped steel structure includes a vertical plate with two slopes on both sides of the top, the vertical plate is vertically arranged, and the two ends of the slopes on both sides of the vertical plate are lapped on the annular edge of the top suction port of the low pressure pump water inlet pipe. A plug rod passes through the vertical plate on both sides and is lapped at both ends on the annular edge of the top suction port of the low pressure pump water inlet pipe.
[0006] In the above technical scheme, a more specific scheme can be: the top of the slopes on both sides of the vertical plate is transitioned by a circular arc.
[0007] Further: the plug rod is square.
[0008] Further: the slopes on both sides of the vertical plate are symmetrically arranged.
[0009] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects compared with the prior art:
[0010] The anti-clogging device for the low-pressure pump inlet of this deaerator uses a cross-shaped device made of ordinary carbon steel plate at the inlet of the deaerator's low-pressure pump. Compared with the flat anti-clogging device, the advantage of this device is that it can effectively prevent the steel plate from falling off and completely covering the inlet. Even if the steel plate falls off, the fallen object can slide to both sides and will not completely cover the inlet. Water can be drawn away from where the vertical plate is upright. This can avoid the situation where the low-pressure pump cannot draw water due to the internal steel structure falling off, thus preventing the cooling of the fume hood. It can effectively improve the stability and functionality of the equipment operation. Attached Figure Description
[0011] Figure 1 This is an isometric view of an embodiment of this utility model;
[0012] The diagram shows: absorption port 1, insertion rod 2, vertical plate 3, ramp 3-1, and arc transition section 3-2. Detailed Implementation
[0013] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:
[0014] like Figure 1 The deaerator low-pressure pump suction port anti-clogging device shown includes a cross-shaped steel structure on the suction port 1 of the low-pressure pump inlet pipe.
[0015] The cross-shaped steel structure includes a vertically erected triangular-shaped vertical plate 3 with ramps 3-1 on both sides. The ends of the ramps on both sides of the vertical plate 3 rest on the annular edge of the absorption port 1 at the top of the low-pressure pump inlet pipe. The top of the ramps on both sides of the vertical plate transitions with an arc, forming an arc transition section 3-2, so that the middle of the top of the vertical plate also makes point contact with the falling steel plate, preventing it from being supported and sliding down the ramps. The symmetrical arrangement of the ramps on both sides of the vertical plate also ensures that the vertical plate is subjected to uniform stress. A square-shaped insert rod 2 passes through both sides of the vertical plate and rests on the annular edge of the absorption port 1 at the top of the low-pressure pump inlet pipe. This facilitates the support of the entire cross-shaped steel structure on the annular edge of the absorption port.
[0016] The anti-clogging device for the low-pressure pump inlet of this deaerator uses a cross-shaped device made of ordinary carbon steel plate at the inlet of the deaerator's low-pressure pump. Compared with the flat anti-clogging device, the advantage of this device is that it can effectively prevent the steel plate from falling off and completely covering the inlet. Even if the steel plate falls off, the fallen object can slide to both sides and will not completely cover the inlet. Water can be drawn away from where the vertical plate is upright. This can avoid the situation where the low-pressure pump cannot draw water due to the internal steel structure falling off, thus preventing the cooling of the fume hood. It can effectively improve the stability and functionality of the equipment operation.
[0017] The device protects the low-pressure pump suction port inside the deaerator, so that the falling of the internal steel structure will not block the suction port and affect production; the inverted V-shaped design is to prevent the steel plate from falling on the device and sliding to the two sides along the inclined surface of the steel plate, so as to not affect the water suction amount. The device effectively solves the unplanned shutdown caused by the low-pressure pump being unable to suck water due to the falling of the steel structure inside the deaerator, and further improves the efficiency and stability of the converter steelmaking.
