Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for high-speed filters, and in particular to a backwashing device for a continuous casting turbid ring high-speed filter. Background Technology

[0002] The existing design of a continuous casting high-speed ring filter for air scouring involves only one 3-inch air pipe and one DN100 water pipe inserted under the filter media. Figure 1 As shown, this structure suffers from poor and uneven gas mixing and scrubbing effects in actual production. Furthermore, in areas with high gas volume, it can cause the filter media to tumble or even leak, ultimately leading to poor backwashing performance of the high-speed filter, a high amount of residual suspended solids in the filter media, and a rapid increase in pressure differential after backwashing. Additionally, the poor backwashing effect and long backwashing cycle easily increase backwashing water, gas, and electricity consumption. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-speed filter backwashing device, which can solve the problems of existing backwashing methods where large air volumes cause filter media to roll or even run away, resulting in poor backwashing effect of high-speed filters, more suspended solids remaining in the filter media, and rapid increase in pressure differential after backwashing.

[0004] To solve the above problems, the technical solution of this utility model is as follows: This high-speed filter backwashing device includes a filter tank, an air inlet pipe, and a water inlet pipe. An air pipe ring and a water pipe ring are arranged below the filter media inside the filter tank; the air pipe ring has multiple evenly distributed exhaust holes and is connected to the air inlet pipe located outside the filter tank; the water pipe ring has multiple evenly distributed drain holes and is connected to the water inlet pipe outside the filter tank.

[0005] A more specific embodiment of the above technical solution is that the water pipe ring is located above the gas pipe ring.

[0006] Furthermore, the water pipe ring is a steel pipe with a specification of DN100.

[0007] Furthermore, the tracheal ring tube is a 3-inch steel pipe.

[0008] Furthermore: an air intake control valve is provided on the air intake pipe; a water intake control valve is provided on the water intake pipe.

[0009] Compared with existing technologies, the above technical solution has the following advantages:

[0010] The backwash air pipe and backwash water pipe used in this utility model are both DN100 ring pipes. Both ring pipes have circular holes. The uniform distribution of backwash air and water allows the gas to scrub and agitate the filter media, thereby greatly improving the gas scrubbing and overall backwashing effect of the high-speed filter. The backwashing cycle is increased from the original 2 hours to 4 hours, and the backwash water consumption, gas consumption and power consumption are greatly reduced. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0015] Figure 1 This is a schematic diagram of the backwashing device structure of a conventional continuous casting high-speed filter. The air scrubbing pipeline arranged below the filter media 2 inside the filter tank 1 consists of only one 3-inch straight air pipe and one DN100 straight water pipe inserted under the filter media. The straight air pipe and straight water pipe are respectively connected to the air inlet pipe and water inlet pipe outside the filter tank 1. The left and right arrows in the figure are the entry paths of backwash water and backwash gas, respectively. This method has poor stirring and scrubbing effects, which has been described in detail in the background art and will not be repeated here.

The air pipe ring 3 is a 3-inch steel pipe with multiple evenly distributed vent holes. It connects to an air inlet pipe 4 outside the filter tank 1, and an air inlet control valve 5 is installed on the air inlet pipe 4. The water pipe ring 8 is a DN100 steel pipe with multiple evenly distributed drain holes. It connects to a water inlet pipe 6 outside the filter tank 1, and a water inlet control valve 7 is installed on the water inlet pipe 6. The water pipe ring 8 is located above the air pipe ring 3.
