The present invention is achieved through the following technical solutions: a gasification furnace membrane-type water-cooled wall series internal parts support device, which is characterized in that it includes a short tube, the short tube is fixed on the shell, and the short tube is connected to the convex The flange is welded and connected, and the internal thread of the flange is connected with a lead screw, and the lead screw and the flange are fixed by a lock nut; the tail of the lead screw is fixedly connected with a baffle, and the baffle is welded to the sleeve, so A spring and a movable rod are installed in the bushing, one end of the movable rod is located in the bushing and is in contact with the spring, and the other end is in contact with the reinforcing ring, and the reinforcing ring is fixed on the membrane water cooling wall.

The present invention is a support device for membrane water-cooled wall internals in a gasifier. It mainly adjusts the lead screw of the support device to make the movable rod contact with the reinforcement ring, and through the spring elasticity in the casing, it solves the problem of membrane water cooling. Thermal expansion of wall interiors or interiors of similar products. The device mainly includes a short tube, the short tube is used to connect the housing, and the inside of the short tube is the moving space of the lead screw, the lead screw is connected with the flange by thread, the length of the lead screw can be adjusted, and the lead screw and the flange are locked by locking The nut is fixed, the other end of the lead screw is fixedly connected to the baffle, the baffle is welded to the casing, a spring and a movable rod are arranged in the casing, one end of the movable rod is located in the casing and contacts the spring, and the other end contacts the reinforcing ring, and the reinforcing ring It is fixedly connected with the membrane water cooling wall, and the position of the movable rod is buffered by the elasticity of the spring, so as to adjust the position of the membrane water cooling wall during thermal expansion. At the same time, the coaxiality of the membrane water cooling wall and the shell can also be adjusted by locking the nut Lock adjustment. The specific operation of the present invention is as follows: before the shell and the membrane water wall are put into use, the short tube is fixedly welded on the shell, and the flange is welded on, the lock nut is screwed into the lead screw, and then the lead screw is screwed into the boss. Fix the lead screw and the flange with a lock nut, then install the spring and the movable rod in the sleeve, and make the spring lean against the baffle, the other end of the movable rod is in contact with the reinforcement ring, and the reinforcement ring is fixed on the water cooling wall. After the assembly is completed, the movable rod is in contact with the reinforcement ring by adjusting the lead screw of the support device, and the elasticity of the spring in the casing buffers the thermal expansion of the internal parts of the membrane water-cooled wall or similar products. The axis is adjusted by locking the lock nut.

Preferably, in order to securely connect the short tube to the housing, ribs are welded between the short tube and the housing.

Compared with the prior art, the present invention has the following beneficial effects: the positioning support of the present invention is safe and reliable, not only can play a supporting role, but also can regulate the coaxiality of the internal parts and the shell, and effectively ensure the axis of the internal parts of the water-cooled wall series. It solves the problem of thermal expansion of internal parts, reduces the problem of opening holes in the equipment shell, and avoids leakage caused by opening holes and defects in the welding of connecting pipes and shells. The invention has strong applicability, simple structure, and is easy to use. Convenient, easy to center, and a practical device that can effectively ensure the thermal expansion of the internal parts of the equipment.
