AI Technical Summary
When the pellets from the vertical shaft furnace pass through the single or double flange funnel, the temperature is too high, which reduces the strength of the steel plate of the funnel body, causes frequent damage, and affects the normal operation of the equipment.
A cooling water circulation shell is installed outside the single or double flange funnel body to form a cavity and circulate cooling water. The water is connected to an external water tank and condenser through inlet and outlet water pipes to reduce the funnel temperature.
It extends the service life of single and double flange funnels, reduces equipment downtime due to malfunctions, lowers production costs, and improves equipment reliability and production efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a discharging equipment technical field, concretely relates to a water -cooling single double flange discharging device. BACKGROUND
[0002] Single double flange funnels are used to connect between the ore discharging funnel of the vertical furnace belt cooling machine and the belt cooling machine, when the pellet ore passes through the single double flange funnel, the temperature is at 700-800 DEG C, with the improvement of the pellet ore output of the vertical furnace, the pellet temperature is still improved, the temperature of the single double flange funnel is also raised, causing the damage of the funnel body steel plate after the strength reduction. SUMMARY
[0003] The utility model discloses a water -cooling single double flange discharging device, which reduces the temperature of the funnel itself and improves the online use time of the funnel.
[0004] In order to solve the problems in the background art, the utility model adopts the following technical scheme: a single double flange funnel body and a cooling water circulation shell are included, the single double flange funnel body is sleeved with the cooling water circulation shell, a cavity is formed between the cooling water circulation shell and the outer wall of the single double flange funnel body, cooling water is arranged in the cavity, a water inlet pipe and a water outlet pipe are installed on the cooling water circulation shell, the water inlet pipe and the water outlet pipe are connected with an external water tank respectively, and a condenser is arranged in the water tank.
[0005] The single double flange funnel body is shaped, and the cooling water circulation shell is shaped according to the single double flange funnel body.
[0006] The water inlet pipe is located at the lower part of the cooling water circulation shell, and the water outlet pipe is located at the upper part of the cooling water circulation shell.
[0007] The utility model has the advantages of:
[0008] 1. The service life of the single double flange funnel is prolonged.
[0009] 2. The equipment downtime caused by the damage of the single double flange funnel is reduced.
[0010] 3. The downtime of the vertical furnace belt cooling machine is reduced.
[0011] 4. The service life of the equipment is prolonged, and the production cost is reduced. DRAWINGS

[0013] Figure 2 It is the side view of the utility model;
[0014] Figure 3is a plan view of the utility model. DETAILED DESCRIPTION
[0015] With reference to the drawings, the utility model specifically adopts the following implementation ways: including single-double flange funnel body 1 and cooling water circulation shell 2, single-double flange funnel body 1 is sheathed with cooling water circulation shell 2, and the cavity is formed between cooling water circulation shell 2 and the outer wall of single-double flange funnel body 1, cooling water is installed in the cavity, water inlet pipe 3 and water outlet pipe 4 are installed on cooling water circulation shell 2, water inlet pipe 3 and water outlet pipe 4 are connected with external water tank respectively, and condensing machine is installed in the water tank. Single-double flange funnel body 1 is shaped, and cooling water circulation shell 2 is shaped along single-double flange funnel body 1. Water inlet pipe 3 is located at the lower part of cooling water circulation shell 2, and water outlet pipe 4 is located at the upper part of cooling water circulation shell 2.
[0016] The water-cooled single-double flange blanking device is made of 20MM thick steel plate, cooling water circulation shell 2 is added to the outer side of single-double flange funnel body 1, the temperature of single-double flange funnel body 1 is reduced, and the online use time of the funnel is improved.
[0017] In summary, the water-cooled single-double flange blanking device increases the service life of single-double flange funnel, reduces the equipment downtime caused by single-double flange funnel damage, reduces the downtime of shaft furnace with cooling machine, and improves the annual output of shaft furnace by 5700 tons. The original single-double flange funnel has an online use time of 6 months, and the manufacturing cost is 12,000 yuan; the improved single-double flange funnel has a manufacturing cost of 16,000 yuan, an online use time of 48 months, and an annual cost saving of (12,000 yuan / 6 months-16,000 yuan / 60 months) *12 months=20,800 yuan. Three shaft furnaces are equipped with six single-double flange funnels, and the annual cost saving is 124,800 yuan.
