Description

Technical Field

[0001] The utility model belongs to the field of pipelines, and is specifically a pressure-maintaining cooling water device for a glass furnace. Background Art

[0002] The pressure-maintaining cooling water system is part of the furnace cooling technology. Its main function is to maintain the pressure inside the furnace stable and prevent the furnace body from deforming due to temperature changes. Under high temperature, the furnace body may deform due to thermal expansion and contraction, which will affect the sealing and service life of the furnace. By using pressure-maintaining cooling water, the temperature change of the furnace body can be controlled by water cooling during the cooling process of the furnace, and the shape and structure of the furnace can be kept stable.

[0003] The pressure-maintaining cooling water system usually includes a cooling water circulation system, a water cooler, a water pump, a valve, and other related control equipment. After the cooling water absorbs heat from the furnace, it is cooled by the water cooler and then recycled. In this process, the system needs to be connected using thermal pipes.

[0004] The existing thermal pipelines are mostly installed by welding sections of the pipeline together through flanges. This installation has the following problems: first, when the thermal pipeline is not welded, its two sides are equivalent to one side of the cross section, and the inner pipe, insulation layer, etc. inside are all exposed. In this way, before welding, it is easy to be damaged, and other impurities enter the insulation layer and affect the insulation effect; second, after welding, all the thermal pipelines are equivalent to a whole. In this way, if the subsequent pipelines are damaged, it is difficult to repair and replace the damaged part of the pipeline. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a glass furnace pressure-maintaining cooling water device, including an inner tube, a heat-insulating tube and an outer tube, the inner tube is a stainless steel tube, and one end of the inner tube extends to the outside of the outer tube, the outer peripheral side of the inner tube is fixedly sleeved with a sealing ring located outside the outer tube and in contact with one side of the outer tube, the other end of the inner tube is connected with a connecting tube with an outer diameter equal to its inner diameter and located outside the outer tube, and the outer peripheral side of the connecting tube is fixedly sleeved with a sealing ring located outside the outer tube and in contact with the other side of the outer tube 2. The insulation pipe is composed of an insulation layer, a reinforcement layer and an anti-corrosion layer from the inside to the outside, and the insulation layer covers the outer surface of the inner pipe; the outer pipe is a stainless steel pipe, and the inner wall of the outer pipe is in contact with the anti-corrosion layer. The outer pipe, the insulation pipe, the inner pipe, the sealing ring 1, the connecting pipe and the sealing ring 2 cooperate to form a thermal node pipe, and two arc-shaped clamping plates with inner curvatures matching the outer peripheral sides of the connection between each two adjacent thermal node pipes are symmetrically arranged, and a fixing mechanism for fixing the two is arranged between each two adjacent arc-shaped clamping plates.

[0006] Beneficial effect: In the present invention, the outer tube, the insulation tube, the inner tube, the sealing ring 1, the connecting tube and the sealing ring 2 cooperate to form a thermal node tube, and the outer peripheral side of the connection between each two adjacent thermal node tubes is symmetrically provided with two arc-shaped clamping plates with inner curvatures matching therewith, and the two arc-shaped clamping plates can be fixed by a fixing mechanism. Through the above arrangement, on the one hand, the thermal pipeline is spliced ​​by thermal node tubes enclosed by multiple insulation layers, so that the insulation layer will not be damaged before the thermal pipeline is welded. On the other hand, if a thermal node tube is damaged, it only needs to be replaced by removing the fixing mechanism and replacing the thermal node tube, which is convenient and quick.

[0014] The glass furnace pressure-maintaining cooling water device provided in this specific embodiment is as follows: Figure 1-4As shown, it includes an inner tube 1, an insulation tube 2 and an outer tube 3, wherein: the inner tube 1 is a stainless steel tube, and one end of the inner tube 1 extends to the outside of the outer tube 3, and the outer peripheral side of the inner tube 1 is fixedly sleeved with a sealing ring 4 located outside the outer tube 3 and in contact with one side of the outer tube 3, and the insulation tube 2 on one side is sealed by the sealing ring 4, and the other end of the inner tube 1 is connected with a connecting tube 5 whose outer diameter is equal to its inner diameter and located outside the outer tube 3, and the outer peripheral side of the connecting tube 5 is fixedly sleeved with a sealing ring 2 6 located outside the outer tube 3 and in contact with the other side of the outer tube 3, and the insulation tube 2 on the other side is sealed by the sealing ring 2 6; the insulation tube 2 is composed of an insulation layer, a reinforcement layer and an anti-corrosion layer from the inside to the outside, wherein the insulation layer covers the outer surface of the inner tube 1; The outer tube 3 is a stainless steel tube, the inner wall of the outer tube 3 is fitted with the anti-corrosion layer, the outer tube 3, the insulation tube 2, the inner tube 1, the sealing ring 1 4, the connecting tube 5 and the sealing ring 2 6 cooperate to form a thermal node tube, and the outer peripheral side of the connection between each two adjacent thermal node tubes is symmetrically provided with two arc-shaped clamping plates 7 with inner curvatures matching therewith, and a fixing mechanism 8 for fixing the two is provided between each two adjacent arc-shaped clamping plates 7; through the above arrangement, on the one hand, the thermal pipeline is spliced ​​by thermal node tubes enclosed by multiple insulation layers, so that the insulation layer will not be damaged before the thermal pipeline is welded, and on the other hand, if a thermal node tube is damaged, it only needs to be replaced by removing the fixing mechanism 8 and replacing the thermal node tube, which is convenient and quick.

[0015] Each fixing mechanism 8 includes two groups of matching blocks 801 respectively fixed to the upper and lower ends of the corresponding two arc-shaped clamping plates 7, one group of matching blocks 801 is penetrated by a through hole 802, and the other group of matching blocks 801 is fixedly connected with a stud 803 passing through the corresponding through hole 802, and the outer peripheral side of each stud 803 is matched with a locking nut 804 for fixing two adjacent matching blocks 801, so that locking the two matching blocks 801 is equivalent to fixing the two thermal node tubes together.

[0016] In addition to the above:

[0017] First, every two adjacent arc-shaped clamping plates 7 can cooperate to form an annular clamping plate.

One end of each shock-absorbing block 9 is fixed to the outer wall of the insulation tube 2, and the other end of each shock-absorbing block 9 is fixedly connected to the inner wall of the outer tube 3. Through the action of these shock-absorbing blocks 9, the thermal pipeline can be buffered when it is vibrated, reducing the possibility of pipeline damage. In addition, due to the presence of sealing ring 1 4 and sealing ring 2 6, the blank layer is equivalent to being sealed into a vacuum layer, and the vacuum layer also has a certain effect on thermal insulation.
