Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a cooling water jacket and a glass feeder. Background Art

[0002] The main function of the glass feeder is to continuously transport the glass raw materials to the pool furnace, which will melt the glass raw materials. Since the temperature of the pool furnace is very high, the discharge end of the glass feeder needs to extend into the pool furnace during the feeding process. Since the temperature inside the furnace is very high, a cooling water jacket needs to be installed at the discharge end of the feeder.

[0003] When the coolant enters the traditional cooling water jacket, it is discharged from the circulation outlet before the coolant fills the chamber, resulting in a gap inside the water jacket. Since the gap cannot be cooled by the coolant, local hot melting problems are prone to occur. Utility Model Content

[0022] Reference Figure 1The utility model proposes a cooling water jacket, comprising: a sleeve 1, one end of the sleeve 1 is the front end, and the other end is the rear end; a water inlet 11 and a water outlet 12 are provided near the rear end of the sleeve 1, and an annular cavity coaxial with the sleeve 1 and a water guide pipe 2 arranged in the annular cavity are provided between the inner and outer walls of the sleeve 1. The annular cavity includes a water outlet cavity 3 near the front end of the sleeve 1 and a water inlet cavity 4 near the rear end of the sleeve 1 and separated from the water outlet cavity 3, and the water inlet cavity 4 is connected with the water inlet 11, and the water outlet cavity 3 is connected with the water outlet 12; the water guide pipe 2 is located on the side away from the water outlet 12, so that when the sleeve 1 is placed horizontally, when the water outlet 12 is in the upper position, the water guide pipe 2 is in the lower position.

[0023] One end of the water guide pipe 2 is connected to the water inlet chamber 4, and the other end is located at the end of the water outlet chamber 3 away from the water inlet chamber 4 and is connected to the water outlet chamber 3. The cooling water can only enter the water inlet chamber 4 from the water inlet 11 first, and then be guided to the water outlet chamber 3 through the water guide pipe 2 and from the front end of the water outlet chamber 3 to gradually fill the entire water outlet chamber 3 from the front end to the rear end of the water outlet chamber 3, and when the water outlet chamber 3 is completely filled, it overflows from the water outlet 12 located at the rear end. This ensures that the cooling water fills the entire water outlet chamber 3, avoiding the problem of local thermal damage at the front end of the cooling water jacket.

[0024] In a further embodiment, the number of the water conduits 2 is one or more.

[0025] Reference Figure 2 The annular cavity is partitioned by the baffle plate 5 to form a water outlet cavity 3 located on one side of the baffle plate 5 and a water inlet cavity 4 located on the other side of the baffle plate 5; the water pipe 2 is axially arranged in the water outlet cavity 3, and one end of the water pipe 2 close to the water inlet cavity 4 is fixed to the baffle plate 5 and communicated with the water inlet cavity 4, so that the water pipe 2 and the baffle plate 5 are fixed together to form a whole, and the baffle plate 5 supports and fixes the water pipe 2.

[0026] In a further embodiment, the port at the communicating end of the water conduit 2 and the water inlet chamber 4 is flush with the end surface of the water baffle 5 to ensure smooth water inflow.

[0027] Reference Figure 3 The sleeve 1 includes a front end sleeve 101 and a rear end sleeve 102. A clamping cavity is provided between the inner and outer walls of the front end sleeve 101 to form a water outlet cavity 3. A clamping cavity is provided between the inner and outer walls of the rear end sleeve 102 to form a water inlet cavity 4. The water baffle 5 is located between the front end sleeve 101 and the rear end sleeve 102 and is fixedly connected to the two.

[0028] Specifically, the watertight plate 5 and the front sleeve 101 and the rear sleeve 102 may be fixed to each other by welding, flange connection or other connection methods.

[0029] Furthermore, the water inlet 11 and the water outlet 12 are respectively located on two sides of the water baffle 5 .

[0030] In a further embodiment, a flange is provided at one end of the sleeve 1 located at the water inlet chamber 4 away from the water outlet chamber 3 to facilitate installation.

[0031] Reference Figure 4 The utility model provides a glass feeder, comprising: a feed bin 6, a feed screw shaft 7 arranged at the bottom of the feed bin 6, a driving mechanism for driving the feed screw shaft 7 to rotate, a water inlet pipeline 8, a water outlet pipeline 9, and the cooling water jacket as described above, wherein:

[0032] The side wall of the feeding bin 6 is provided with a discharge port, the rear end of the sleeve 1 is docked and fixed with the discharge port, and the water outlet 12 is located above the sleeve 1, and the water guide pipe 2 is located below the sleeve 1. The water inlet pipe 8 is connected to the water inlet 11, and the cooling water is delivered to the water inlet chamber 4 through the water inlet pipe 8. The water outlet pipe 9 is connected to the water outlet 12, and the cooling water in the water outlet chamber 3 is discharged through the water outlet pipe 9. One end of the feeding screw shaft 7 extends into the sleeve 1. When feeding, the front end of the cooling water jacket is extended into the pool furnace, and the driving mechanism drives the feeding screw shaft 7 to rotate to transport the material in the feeding bin 6 into the furnace. The cooling water jacket is set through the discharge port of the feeder, and the structure of the cooling water jacket is improved so that the part of the cooling water jacket extending into the furnace will not be locally hot-melted and deformed due to insufficient filling of the coolant, thereby ensuring that the glass feeder can operate safely for a long time and production is guaranteed.

[0033] In a further embodiment, the water inlet 11 is located above the sleeve 1 .

[0034] In a further embodiment, a flange is provided at the discharge port, and the sleeve 1 is fixed to the flange provided at the discharge port via a flange provided at an end thereof.

This structural design ensures that the cooling water in the water outlet cavity 3 is always kept full, and solves the problem of liquid filling gaps in the traditional cooling water jacket during the process of filling the coolant.
