Description

Filtering device for air conditioner box drain valve

Technical Field

The utility model relates to an air conditioner technical field specifically is a filter equipment for air-conditioning box trap.

Background

The tobacco industry especially cigarette factory all adopts central air conditioning, heats, humidification technology through steam, and the comdenstion water that forms after the steam condensation discharges through the trap, because the pipeline is in high temperature state for a long time, the pipeline easily produces foreign matter such as rust, when the foreign matter is long-pending in the trap, easily causes the trap to block up, leads to the steam extravagant serious, has both influenced the energy consumption and has also influenced the stability of air conditioning box heat supply. Therefore, how to design a filter device to ensure that the trap is not blocked is a technical problem to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of existence among the prior art, providing a filter equipment for air-conditioning box trap, solved the drainage pipe among the prior art and easily produced foreign matters such as iron rust, cause the trap to block up, lead to steam extravagant serious, both influenced the energy consumption and also influenced the problem of the stability of air-conditioning box heat supply.

In order to realize the purpose, the utility model discloses a technical scheme be:

a filtering device for a drain valve of an air conditioner box comprises a water inlet pipe, a water outlet pipe, a cover plate, a filtering box body, a permanent magnet, a filter screen and a sealing ring, wherein the water inlet pipe and the water outlet pipe are respectively connected to a water inlet and a water outlet at two ends of the filtering box body; the filtering box body is of a rectangular box body structure with an opening at the upper end; the cover plate is fixedly arranged on the filtering box body through a fixing screw; the cover plate covers an upper end opening of the filtering box body; the permanent magnet is fixedly arranged in the filter box body; the filter screen is fixedly arranged on the water outlet of the filter box body; the water inlet pipe is connected with a condensed water inlet; the water outlet pipe is connected with the drain valve; and a sealing ring is arranged between the cover plate and the filtering box body for sealing.

Furthermore, there are 3 permanent magnets, 2 of them are fixed on two ends of the lower end face of the cover plate, and another permanent magnet is fixed in the middle of the upper end face of the bottom face of the filter box.

Furthermore, the water inlet pipe and the water outlet pipe are connected with the water inlet and the water outlet on the filtering box body through flanges.

Furthermore, 2 permanent magnets on the end face of the lower part of the cover plate and one permanent magnet on the bottom surface of the filter box body can be detached from the cover plate and the filter box body.

The filtering device for the drain valve of the air conditioner box utilizes the gravity falling principle and the principle that the permanent magnet can absorb the magnetic materials such as rust and the like. When foreign matters flow into the drain valve along with condensed water through the water inlet pipe, the filter box body and the water outlet pipe, the foreign matters of magnetic materials such as rust and the like can be absorbed by the permanent magnet and are adsorbed on the outer surface of the permanent magnet; other foreign matters will be settled at the bottom of the filtering box body under the action of the gravity of the other foreign matters after colliding the permanent magnet and the filtering net. The bottom of the filter box body and the foreign matters on the permanent magnet are removed only by opening the cover plate regularly, so that the phenomenon that the drain valve is blocked due to excessive foreign matters can be prevented. After the implementation, the blockage of the drain valve is avoided, and the labor intensity of operators is reduced.

The utility model discloses the accessible sets up permanent magnet and filter screen in the rose box body, can prevent effectively that the impurity of aquatic from getting into the trap, and causes the trap to block up and damage the condition of trap, has reduced the central air conditioning energy consumption and has also improved the stability of central air conditioning case heat supply.

Drawings

FIG. 1 is a schematic structural diagram of the device of the present invention;

in the figure: 1. the water inlet pipe comprises a water inlet pipe body 2, a fixing screw 3, a cover plate 4, a sealing ring 5, a water outlet pipe 6, a drain valve 7, a permanent magnet 8, a filtering box body 9 and a filtering net.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The filtering device for the drain valve of the air-conditioning box shown in fig. 1 comprises a water inlet pipe 1, a water outlet pipe 5, a cover plate 3, a filtering box body 8, a permanent magnet 7, a filter screen 9 and a sealing ring 4, wherein the water inlet pipe 1 and the water outlet pipe 5 are respectively connected to a water inlet and a water outlet at two ends of the filtering box body 8; the filtering box body 8 is of a rectangular box body structure with an opening at the upper end; the cover plate 3 is fixedly arranged on the filter box body 8 through a fixing screw 2; the cover plate 3 covers the upper end opening of the filter box body 8; the permanent magnet 7 is fixedly arranged in the filter box body 8; the filter screen 9 is fixedly arranged on the water outlet of the filter box body 8; the water inlet pipe 1 is connected with a condensed water inlet; the water outlet pipe 5 is connected with a drain valve 6; a sealing ring 4 is arranged between the cover plate 3 and the filtering box body 8 for sealing; the number of the permanent magnets 7 is 3, wherein 2 permanent magnets 7 are respectively fixed at two ends of the lower end face of the cover plate 3, and the other permanent magnet 7 is fixedly arranged in the middle of the upper end face of the bottom face of the filter box body 8; the water inlet pipe 1 and the water outlet pipe 5 are connected with the water inlet and the water outlet on the filtering box body 8 through flanges; the 2 permanent magnets 7 on the lower end surface of the cover plate 3 and the permanent magnet 7 on the bottom surface of the filter box body 8 can be detached from the cover plate 3 and the filter box body 8.
