Description

Technical field:

[0001] The utility model relates to the technical field of water cooling of reverberatory furnaces, in particular to a novel water cooling charging port device of a reverberatory furnace. Background technology:

[0002] There are generally two feeding methods for the reverberatory furnace body: one is side wall feeding, and the other is furnace top feeding. The side wall feeding adopts manual feeding, which has high labor intensity and low feeding efficiency. At the same time, because the size of the side wall feeding port is large, the heat dissipation of the furnace body is greatly increased, and the fuel utilization rate is reduced; in addition, due to the large size of the side feeding furnace door, the water-cooled beams are used to support it on all sides, which also makes the pipes around the furnace door dense. If there is a water leak, the maintenance is complicated. In view of the above-mentioned disadvantages of the side wall feeding of the reverberatory furnace, the reverberatory furnace currently basically adopts the furnace top feeding method, that is, the reverberatory furnace feeding port device is placed on the reverberatory furnace roof. The traditional feeding port adopts the form of steel plate lined refractory casting material, and then water cooling is used to cool the feeding port. The refractory casting has poor heat transfer effect, not only the water consumption is huge, but also the water cooling effect is poor, so that the service life of the traditional feeding port is only 2-3 months. Frequent cooling and disassembly of the feeding port seriously damages the overall stress of the furnace roof and reduces the furnace life of the reverberatory furnace. Utility model content:

[0003] The utility model aims to provide a novel water-cooled charging port device for a reverberatory furnace, so as to solve the technical problems of large water consumption and poor cooling effect of the liquid reverberatory furnace unloading port in the prior art.

[0004] The content of the utility model: A new type of water-cooled charging port device for a reverberatory furnace, comprising a horizontally arranged water-cooling frame, a water-cooling flow channel with a square flow path arranged in the water-cooling frame, a water-cooling pipe matching the shape of the water-cooling flow channel installed in the water-cooling flow channel, a water inlet pipe installed at the starting end of the water-cooling pipe, a water outlet pipe installed on the water-cooling frame, the water outlet pipe is located at the end of the water-cooling pipe, and a plurality of nozzles are installed on the water-cooling pipe, and the nozzles are used to spray cooling water into the water-cooling flow channel.

[0005] Furthermore, the installation directions of any two adjacent nozzles along the water flow direction are perpendicular.

[0006] Furthermore, the water cooling frame is formed by buckling an upper buckle plate and a lower buckle plate, and water cooling grooves are provided in the upper buckle plate and the lower buckle plate, and the water cooling grooves of the upper buckle plate are buckled with the water cooling grooves of the lower buckle plate to form the water cooling channel.

[0007] Furthermore, the upper buckle plate is welded to the lower buckle plate.

[0008] Furthermore, a positioning column is vertically connected to the water inlet pipe, and a limiting compression spring matching the positioning column is connected to the upper buckle plate and the lower buckle plate. The limiting compression spring is sleeved on the positioning column, and the limiting compression spring limits the water outlet pipe to the center position of the water-cooling channel.

[0009] Furthermore, the water cooling frame is made of Q235 carbon steel, and the water cooling pipe and the nozzle are made of 304 stainless steel.

[0010] The beneficial effects of the utility model are as follows: the utility model subverts the traditional design, uses cheap carbon steel with good heat conductivity to make a water cooling frame, and designs a spray-type water cooling structure in the water cooling frame, so as to maximize the use of the cooling capacity of cooling water in unit volume, save water resources, have good cooling effect, increase the service life of the water cooling feeding port, and ensure the normal operation of the reverberatory furnace. Description of the drawings:

[0011] Figure 1 It is a three-dimensional diagram of the internal structure of the utility model;

[0012] Figure 2 It is a top view of the utility model;

[0013] Figure 3 for Figure 2 Section view along AA;

[0014] In the figure, there are an upper buckle plate 1, a lower buckle plate 2, a water cooling groove 3, a water cooling pipe 4, a water outlet pipe 5, a positioning column 6, a limit compression spring 7, a nozzle 8, and a water inlet pipe 9. Specific implementation method:

[0015] like Figure 1 As shown, a new type of water-cooling charging port device for a reverberatory furnace comprises a horizontally arranged water-cooling frame, a water-cooling flow channel with a square flow path is arranged in the water-cooling frame, a water-cooling pipe 4 matching the shape of the water-cooling flow channel is installed in the water-cooling flow channel, a water inlet pipe 9 is installed at the starting end of the water-cooling pipe 4, a water outlet pipe 5 is installed on the water-cooling frame, the water outlet pipe 5 is located at the end of the water-cooling pipe 4, and a plurality of nozzles 8 are installed on the water-cooling pipe 4, and the nozzles 8 are used to spray cooling water into the water-cooling flow channel; in order to increase the spraying area and achieve spraying without dead angles, the installation directions of any two adjacent nozzles 8 along the water flow direction are perpendicular; the water-cooling frame is formed by buckling an upper buckle plate 1 and a lower buckle plate 2, and water cooling grooves 3 are opened in the upper buckle plate 1 and the lower buckle plate 2, and the water cooling grooves 3 of the upper buckle plate 1 are buckled with the water cooling grooves 3 of the lower buckle plate 2 to form the water cooling flow channel; the upper buckle plate 1 is welded to the lower buckle plate 2.

[0016] like Figure 2 and Figure 3As shown, in order to position the water-cooling pipe 4, a positioning column 6 is vertically connected to the water inlet pipe 9, and a limiting compression spring 7 matching the positioning column 6 is connected to the upper buckle plate 1 and the lower buckle plate 2. The limiting compression spring 7 is sleeved on the positioning column 6, and the limiting compression spring 7 limits the water outlet pipe 5 to the center position of the water-cooling flow channel; the water-cooling frame is made of Q235 carbon steel, and the water-cooling pipe 4 and the nozzle 8 are both made of 304 stainless steel.

[0017] When doing specific work, such as Figure 1 and Figure 2 As shown, the cooling water flows through the water inlet pipe 9, the water cooling pipe 4, the nozzle 8, the water cooling channel, and the water outlet pipe 5 in sequence to complete the cooling operation. In this process, the cooling water sprayed from the nozzle 8 is sprayed onto the inner wall of the water cooling channel. The cooling area is large and the water consumption is small. The cooling water evaporates and absorbs a large amount of hot raw materials to cool the water cooling frame. The cooling effect is good, so that the service life of the water cooling jacket feeding port is increased to 8 to 10 months, which is basically the same as the furnace life of the reverberatory furnace, so that the water cooling feeding port can be remade during the maintenance period of the reverberatory furnace without affecting the normal production.

[0018] The above are only preferred examples of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
