[0002] There are two commonly used catalysts in the degreasing process. One is nitric acid HNO3. The strong oxidizing HNO3 can quickly catalyze and crack POM and is widely used in industrial production, consuming nearly 1,000 tons of HNO3 each year. The other is oxalic acid powder catalytic degreasing: this catalytic degreasing furnace is fed with oxalic acid through an oxalic acid feeder. The feeder has a heating gasification device. After the oxalic acid is gasified into a gaseous state, it is brought into the furnace by nitrogen for catalytic degreasing.
[0003] However, in the use of the existing device, a set of sealing doors are set at the feed port of the continuous furnace to transport materials into the furnace. However, when the sealing doors are opened, the oxalic acid gas in the furnace will leak out, causing waste and polluting the nearby air environment.
[0004] Therefore, in order to solve the above problems, an inlet and outlet sealing mechanism of an oxalic acid catalytic degreasing continuous furnace is proposed. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inlet and outlet sealing mechanism of an oxalic acid catalytic degreasing continuous furnace, comprising: a temporary storage chamber;
[0007] Openings are provided on the front and left side walls of the temporary storage room, a cylinder is fixedly installed on the top surface of the temporary storage room, a sealing door is fixedly connected to the output end of the cylinder, a transparent glass observation window is installed on the top surface and right side wall of the temporary storage room, and a slide rail is fixedly installed on the inner bottom surface of the temporary storage room.
[0008] Preferably, the left end of the temporary storage chamber is communicated with the feed end of the continuous furnace.
[0009] Preferably, the cylinders are provided in two groups, and the two groups of cylinders are correspondingly installed on the upper sides of the two groups of through openings.
[0010] Preferably, the sealing door is located on the inner side of the through opening, and the sealing door is sealingly fitted to the through opening.
[0011] Compared with the prior art, the utility model has the following beneficial effects: by opening openings on the front and left side walls of the temporary storage chamber and respectively arranging sealing doors on the upper sides of the two groups of openings, the utility model can ensure the relative sealing performance in the furnace chamber during the material advancement process, reduce the leakage of oxalic acid gas, and thus improve the use effect of the device.
[0012] The utility model is provided with a temporary storage chamber, and two groups of sealing doors are respectively blocked at the inner sides of the two groups of openings, so that the inner side of the temporary storage chamber and the furnace are sealed. When materials need to be pushed, a group of openings at the front are opened, and the tray carrying the materials is pushed into the temporary storage chamber. At this time, a group of sealing doors located on the left side of the temporary storage chamber is fixed, so that the inner side of the furnace remains sealed. Then the cylinder is started to lower the sealing door located on the front side of the temporary storage chamber. At this time, the inner side of the temporary storage chamber is sealed. Then the cylinder is started again to raise the group of sealing doors located on the left side of the temporary storage chamber, so that the temporary storage chamber is communicated with the inside of the furnace. The tray carrying the materials in the temporary storage chamber can be pushed into the furnace, and finally the sealing door is lowered. Because the two groups of sealing doors are opened and closed alternately when the materials enter the furnace, the leakage of oxalic acid gas can be reduced, thereby improving the use effect of the device.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-3 , an embodiment provided by the utility model:
[0019] The temporary storage chamber 1 and the cylinder 12 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.
[0020] An inlet and outlet sealing mechanism of an oxalic acid catalytic degreasing continuous furnace comprises: a temporary storage chamber 1;
[0021] A through opening 11 is provided on the front and left side walls of the temporary storage chamber 1, a cylinder 12 is fixedly installed on the top surface of the temporary storage chamber 1, a sealing door 13 is fixedly connected to the output end of the cylinder 12, a transparent glass observation window 14 is installed on the top surface and the right side wall of the temporary storage chamber 1, and a slide rail 15 is fixedly installed on the inner bottom surface of the temporary storage chamber 1. By providing the through opening 11 on the front and left side walls of the temporary storage chamber 1 and arranging sealing doors 13 on the upper sides of the two groups of through openings 11, the relative sealing performance in the furnace cavity can be guaranteed during the process of material advancement, and the leakage of oxalic acid gas can be reduced, so as to improve the use effect of the device.
[0022] Furthermore, the left end of the temporary storage chamber 1 is communicated with the feeding end of the continuous furnace, and the materials can be pushed to the left side into the continuous furnace through the temporary storage chamber 1.
[0023] Furthermore, two groups of cylinders 12 are provided, and the two groups of cylinders 12 are correspondingly installed on the upper sides of the two groups of through openings 11 , and the cylinders 12 provide power for the lifting and lowering activities of the sealing door 13 .
[0024] Furthermore, the sealing door 13 is located on the inner side of the through opening 11, and the sealing door 13 is sealed to the through opening 11. When the sealing door 13 is raised, the material can move inside and outside the temporary storage chamber 1. When the sealing door 13 is lowered, the leakage of oxalic acid gas can be reduced to improve the use effect of the device.
[0025] Working principle: Before use, two groups of sealing doors 13 are respectively blocked on the inner sides of the two groups of through openings 11, so that the inner side of the temporary storage chamber 1 and the furnace are sealed. When materials need to be pushed, a group of through openings 11 on the front are opened, and the tray carrying the materials is pushed into the temporary storage chamber 1. At this time, a group of sealing doors 13 on the left side of the temporary storage chamber 1 is fixed, so the inside of the furnace remains sealed. Then start the cylinder 12 to lower the sealing door 13 on the front side of the temporary storage chamber 1. At this time, the inner side of the temporary storage chamber 1 is sealed. Then start the cylinder 12 to raise a group of sealing doors 13 on the left side of the temporary storage chamber 1, so that the temporary storage chamber 1 is connected to the inside of the furnace. The tray carrying the materials in the temporary storage chamber 1 can be pushed into the furnace, and finally the sealing door 13 is lowered. Since the two groups of sealing doors 13 are opened and closed alternately when the materials enter the furnace, the leakage of oxalic acid gas can be reduced, thereby improving the use effect of the device.
