Specifically, the 90 ° welded elbow can be customized according to the needs or purchased in the market.
In this embodiment, the first horizontal tube 11, the first vertical tube 12, the second horizontal tube 13, the third horizontal tube 21, the second vertical tube 22 and the fourth horizontal tube 23 are preferably cold-drawn seamless flat tubes, the thickness and the size of the cold-drawn seamless flat tubes are determined according to the thickness and the temperature of the glass solution 101 in the glass melting furnace 100, the bearing pressure is about 8MPa to 60MPa, and the method is suitable for the working environment of the glass melting furnace 100 with high temperature and high pressure, and the cold-drawn seamless flat tubes are not easy to be broken by stress and have good corrosion resistance.
In the present embodiment, as shown in fig. 1, 2 and 6, the circulation line 30 includes a fifth horizontal pipe 31 and a sixth horizontal pipe 32 sequentially horizontally interposed between the second horizontal pipe 13 and the third horizontal pipe 21; a first connecting pipe 321 is arranged between the outlet end of the second horizontal pipe 13 and the inlet end of the fifth horizontal pipe 31, and two ends of the first connecting pipe 321 are respectively welded with the first welding elbow 14 and the fifth horizontal pipe 31; a second connecting pipe 322 is arranged between the outlet end of the fifth horizontal pipe 31 and the inlet end of the sixth horizontal pipe 32, and two ends of the second connecting pipe 322 are respectively welded with the fifth horizontal pipe 31 and the second horizontal pipe 13; a third connecting pipe 323 is arranged between the outlet end of the sixth horizontal pipe 32 and the inlet end of the third horizontal pipe 21, and two ends of the third connecting pipe 323 are respectively welded with the sixth horizontal pipe 32 and the third horizontal pipe 21. When in use, the cooling water in the first horizontal pipe 11 enters the fifth horizontal pipe 31 through the first welding elbow 14 and the first connecting pipe 321, flows into the sixth horizontal pipe 32 through the second connecting pipe 322, and finally flows into the water outlet pipeline 20 through the third connecting pipe 323, so that the cooling water in the neck water bag flows in a reciprocating and circulating way in the circulating pipeline 30, the cooling water sequentially flows through the fifth horizontal pipe 31 and the sixth horizontal pipe 32, the contact area between the glass solution 101 and the neck water bag is increased, the contact time between the cooling circulating water and the glass solution 101 is prolonged, the heat exchange rate of the glass solution 101 is accelerated, and the time for reducing the solution temperature is shortened.
In the present embodiment, the fifth horizontal pipe 31, the sixth horizontal pipe 32, the first connecting pipe 321, the second connecting pipe 322, and the third connecting pipe 323 are preferably cold drawn seamless flat tubes. Each pipe section of the neck water drum adopts cold-drawing seamless steel pipes to ensure the integral strength of the neck water drum and prolong the service life of the neck water drum.
In the present embodiment, as shown in fig. 1, 2 and 6, a gap 311 for a glass solution 101 to communicate is reserved between the fifth horizontal pipe 31 and the second horizontal pipe 13, between the sixth horizontal pipe 32 and the fifth horizontal pipe 31, and between the third horizontal pipe 21 and the sixth horizontal pipe 32; that is, three flow layer gaps 311 are reserved between the second horizontal pipe 13, the fifth horizontal pipe 31, the sixth horizontal pipe 32 and the third horizontal pipe 21, which are adjacently arranged in this order, and when the neck pack is placed in the glass melting furnace 100, the glass solution 101 can flow in the flow layer gaps 311. Thus, on one hand, the heat exchange area of the neck water drum is increased, and the heat exchange rate of the glass solution 101 can be further improved, so that the cooling process of the glass melting furnace 100 is more energy-saving and efficient; in addition, when the glass solution 101 passes through the flowing layer gap 311, the whole glass solution 101 with larger original thickness is divided into a plurality of solution layers with smaller thickness, and the glass solution 101 is extruded in the flowing layer gap 311, so that the gas dissolved in the glass solution 101 is released, and the bubbles in the glass solution 101 can be effectively eliminated, so that the quality and the yield of glass products are improved.
In the present embodiment, as shown in fig. 1, 2 and 6, the height of the flow layer gap 311 is preferably 2cm to 4cm, that is, the height of the interval gap between the fifth horizontal pipe 31 and the second horizontal pipe 13, between the sixth horizontal pipe 32 and the fifth horizontal pipe 31, and between the third horizontal pipe 21 and the sixth horizontal pipe 32 is 2cm to 4cm, and may be specifically 2cm, 2.5cm, 3.5cm, or 4cm. More specifically, when the neck pack is placed in the glass solution 101, the thickness of the glass solution 101 at the front end of the neck pack is generally between 20cm and 60cm, and when the glass solution 101 flows through the neck pack, the glass solution 101 flows out from the flow layer gap 311 having a height of 2cm to 4cm, at this time, the glass solution 101 becomes a solution layer having a thickness of 2cm to 4cm, and the thickness of the glass solution 101 is greatly reduced, so that bubbles in the solution are more easily eliminated.
In this embodiment, as shown in fig. 1, 2 and 4, a plurality of support connectors 312 are further provided between the fifth horizontal pipe 31 and the second horizontal pipe 13, between the sixth horizontal pipe 32 and the fifth horizontal pipe 31, and between the third horizontal pipe 21 and the sixth horizontal pipe 32, and each support connector 312 is welded to the adjacent fifth horizontal pipe 31 and second horizontal pipe 13 or sixth horizontal pipe 32 and fifth horizontal pipe 31 or third horizontal pipe 21 and sixth horizontal pipe 32, respectively. The support connecting piece 312 is welded between the adjacent horizontal pipe sections, so that the probability that the vertical deformation of the horizontal pipe sections occurs due to gravity can be reduced, and the structural stability of the neck water drum can be improved. Specifically, the support connecting member 312 may be a solid steel material such as a common round steel, which is easy to obtain materials and can satisfy the support performance.
Specifically, as shown in fig. 4, the end surfaces of the outlet end of the second horizontal pipe 13 and the inlet end of the fifth horizontal pipe 31 are covered with a first sealing plate 33, the end surfaces of the outlet end of the sixth horizontal pipe 32 and the inlet end of the third horizontal pipe 21 are covered with a second sealing plate 34, and the first sealing plate 33 and the second sealing plate 34 are welded to the corresponding horizontal pipe sections respectively, so as to ensure that the pipe sections of the circulation pipe 30 are stably connected with the water inlet pipe 10 and the water outlet pipe 20 into a whole.
More specifically, as shown in fig. 1, a supporting connector 312 is welded between the side of the fifth horizontal pipe 31, the sixth horizontal pipe 32 and the second vertical pipe 22, which is close to the first vertical pipe 12, and the first vertical pipe 12, so as to further improve the connection stability of the neck water drum.
In this embodiment, as shown in fig. 1 and 2, the streamline neck water drum further includes a water inlet connection pipe 40 connected to the inlet end of the first horizontal pipe 11 and a water return connection pipe 50 connected to the outlet section of the fourth horizontal pipe 23, the water inlet connection pipe 40 is communicated with the water outlet of the external water supply device, the water outlet pipe is communicated with the water return port of the external water supply device, and the pipe lengths of the water inlet connection pipe 40 and the water return connection pipe 50 can be changed and adjusted. In this way, the water inlet connection pipe 40 and the water return connection pipe 50 are provided to connect the neck water pack and the external water supply device, so that the placement distance of the external water supply device is relatively flexible.
In this embodiment, the water inlet connection pipe 40 and the water return connection pipe 50 are preferably seamless steel pipes, and the water inlet connection pipe 40 and the water return connection pipe 50 are respectively welded to the corresponding first horizontal pipe 11 and fourth horizontal pipe 23. Cooling water flows out of the neck water drum, and the temperature reply of the cooling water is improved due to the fact that the cooling water exchanges heat of the glass solution 101, so that the cooling water can be prevented from damaging a connecting pipe due to the fact that the temperature of the cooling water rises too high by using a seamless steel pipe to connect an external water supply device, and a waterway passage between the external water supply device and the neck water drum is damaged.
Specifically, the inlet end of the water inlet connecting pipe 40 and the outlet end of the water return connecting pipe 50 are respectively provided with external threads, and the water inlet connecting pipe 40 and the water return connecting pipe 50 are respectively connected with the water outlet and the water return port of the external water supply device through an AD quick connector.
