Description

Anti-pollution overflow device

Technical Field

The utility model relates to a water treatment technology field, concretely relates to anti-pollution overflow arrangement.

Background

In the water treatment industry, in order to prevent the liquid level of a tank for storing liquid from being too high, an overflow pipe is generally required to be arranged so as to ensure that the actual liquid level does not exceed the designed liquid level; at the same time, many liquids emit polluting gases. An overflow port connected with an overflow pipe is usually arranged at an elevation where the side wall of the tank body is slightly higher than the designed liquid level, and when the actual liquid level in the tank body rises to the height of the overflow hole, the liquid can be discharged through the overflow pipe. After the liquid enters the tank body, the overflow inlet is submerged below the designed liquid level, when the actual liquid level rises to the height of the overflow port, the liquid in the tank body can enter from the overflow inlet and is discharged through the overflow outlet and the overflow pipe. The top end of the overflow pipe of the tank body is provided with an anti-siphon pipe with an upward opening and communicated with the atmosphere, and a vent of the anti-siphon pipe is positioned above the designed liquid level and is higher than the overflow outlet, so that the siphon phenomenon can be prevented. However, when the liquid flows through the overflow pipe, the contaminating gases emitted from the liquid can flow out of the anti-siphon tube, affecting the surrounding environment. If the tank body is positioned in a closed workshop, gas is scattered from the overflow pipe, so that the workshop is easily polluted, and the health of personnel is seriously influenced.

The existing improved overflow device can form water seal by using liquid in a tank to prevent polluting gas from being emitted, but has the following defects: 1) The length of the overflow pipe depends on the height of the tank body and the designed liquid level, and the overflow pipe is longer and more difficult to fix the overflow pipe when the tank body and the designed liquid level are higher; 2) If the solid content in the liquid is large or precipitation is likely to occur, the overflow pipe is likely to be clogged.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments.

As shown in fig. 1, the anti-pollution overflow device of the present embodiment comprises an overflow pipe 2 communicating with a tank 1 and used for discharging liquid in the tank 1, an anti-siphon tube 3 communicating with the overflow pipe 2 and having an upward opening and communicating with the atmosphere, and a water sealing mechanism connected between the anti-siphon tube 3 and the overflow pipe 2 and used for preventing gas emitted from the liquid from passing through the anti-siphon tube 3. Through set up water seal mechanism between anti-siphon 3 and overflow pipe 2, can prevent that the air in the jar body 1 from getting into overflow pipe 2 through anti-siphon 3 and discharging, also prevented that the air that liquid distributes out among the overflow pipe 2 from coming out from anti-siphon 3 to avoid gaseous pollutants's effluvium and influence workshop health environment, and then ensured personnel's healthy.

The water seal mechanism comprises a water seal chamber 4 storing liquid and a connecting pipe 5 communicated with the overflow pipe 2, the anti-siphon pipe 3 and the connecting pipe 5 are communicated with the water seal chamber 4, and the height of the communicated part of the connecting pipe 5 and the overflow pipe 2 is higher than the liquid level of the water seal chamber 4. When the liquid level in the tank body 1 is higher than the vent 31, the liquid overflow pipe 2 automatically flows out, and at the moment, the liquid injected in the water seal chamber 4 in advance is discharged along with the liquid, and is filled with the liquid stored in the tank body 1; when the liquid level in the tank body 1 is gradually reduced and is lower than the vent hole 31 and higher than the overflow outlet, because the vent hole is usually arranged at the top of the tank body 1 to maintain the balance of the air pressure inside and outside the tank body 1, the air pressure at the vent hole 31 is the atmospheric pressure at the moment, the overflow state is still kept in the system, the siphoning phenomenon cannot occur, and a proper amount of liquid still exists in the water seal chamber 4; when the liquid level in the tank body 1 is lower than the overflow outlet, the overflow stops, and the water seal chamber 4 keeps a liquid state. In summary, the water seal chamber 4 is always in a liquid state.

The water seal chamber 4 is a U-shaped pipe, and two ends of the U-shaped pipe are respectively communicated with the anti-siphon pipe 3 and the connecting pipe 5. The selected U-shaped pipe not only has the water seal chamber 4, can achieve good water seal effect, but also is very convenient to install and low in price.

The vent 31 of the anti-siphon tube 3 is at a higher elevation than the highest elevation 21 of the overflow tube 2. Can ensure the anti-siphon effect and leave enough space for the water seal mechanism.

The inlet 22 of the overflow pipe 2 is located below the lowest level 11 of the tank 1. In order to ensure the effective volume of the tank body 1, an overflow port is usually arranged in the area of the upper part of the tank body 1, an overflow pipe 2 overflows from top to bottom, and water is not deposited in the pipe and is not easy to block.

The tank body 1 is a closed cavity structure, and the top of the tank body 1 is provided with an exhaust mechanism communicated with the atmosphere. The exhaust mechanism exhausts the polluted gas emitted from the liquid, further reduces the possibility that the polluted gas is exhausted from the overflow pipe 2, and also ensures that the air pressure in the tank body 1 is the same as the air pressure at the outlet of the overflow pipe 2, thereby ensuring the normal work of the anti-siphon pipe 3.

The water seal mechanism and the anti-siphon pipe 3 are arranged inside the tank body 1. The water seal mechanism and the anti-siphon pipe 3 are arranged outside the tank body 1, and need to occupy the external space, so that the occupied space of the equipment is increased, the water seal mechanism and the anti-siphon pipe can be arranged inside the tank body 1, the manufacturing and the installation of the device can be ensured to be more convenient, holes do not need to be formed in the external overflow pipe 2 again, the occupied space of the equipment is greatly reduced, the external structure of the equipment is greatly simplified, and the cleaning and sweeping are facilitated.

The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments. For those skilled in the art, the modifications and changes obtained without departing from the technical idea of the present invention shall be considered as the protection scope of the present invention.
