Description

Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a steam and water dual-purpose floor drain. Background Art

[0002] In the process of cigarette production, steam is required for heating and humidifying tobacco, injecting liquid, heating equipment, etc. However, when the equipment is shut down, the steam in the pipeline will condense into water. When the equipment is working again, the condensed water in the pipeline needs to be discharged from the equipment straight pipe. In the process of discharging condensed water, part of the steam will overflow from the floor drain, affecting the temperature and humidity of the workshop and causing adverse effects on cigarette production.

[0003] Chinese patent CN217175152U discloses a floor drain device for discharging condensed water from equipment, but the floor drain device cannot drain water accumulated on the floor.

[0004] Based on this, a floor drain is needed which does not affect the discharge of surface water on the ground into the sewer and can prevent the steam in the sewer from overflowing. Utility Model Content

[0005] In view of the above problems, the utility model provides a dual-purpose floor drain for steam and water, which forms a liquid seal by storing accumulated water on the floor, thereby ensuring the normal discharge of accumulated water on the floor and effectively avoiding steam overflow when draining condensed water.

[0006] Specifically, the utility model is achieved as follows:

[0007] A steam and water dual-purpose floor drain, comprising:

[0008] The connecting part has a top connected to the straight discharge pipe of the equipment and a bottom extending into the sewer;

[0009] A liquid accumulation chamber is provided at one side of the connecting portion, the bottom of the liquid accumulation chamber is connected to the connecting portion through a connecting pipe for drainage; the connecting pipe extends into the liquid accumulation chamber, water accumulates in the liquid accumulation chamber, and the height of the accumulated water is less than the length of the connecting pipe extending into the liquid accumulation chamber;

[0010] A liquid seal component is arranged on the top of the connecting pipe, one end of which is connected to the liquid accumulation cavity, and the other end is connected to the connecting pipe, and the accumulated water covers the end of the liquid seal component connected to the liquid accumulation cavity;

[0011] The end cover is fixed to the connecting portion and the top of the liquid accumulation chamber, and is provided with a detachable top plate. The top plate is located directly above the liquid accumulation chamber and is provided with a plurality of water flow holes.

[0012] Furthermore, the liquid seal assembly comprises:

[0013] A toothed portion, located at the top of the connecting pipe;

[0014] The sealing cover is arranged on the upper part of the toothed part, and its diameter is larger than the diameter of the connecting pipe, so that a channel is formed between the inner wall of the sealing cover and the outer wall of the connecting pipe, the accumulated water covers the entrance of the channel, and the channel is connected with the connecting pipe through the notch of the toothed part.

[0015] Furthermore, the top of the sealing cover is in a cone shape.

[0016] Furthermore, a sealing gasket is provided at the bottom of the outer edge of the end cover. When in use, the sealing gasket contacts the ground and is used to seal the gap at the connection between the end cover and the ground.

[0017] Furthermore, a sealing ring is provided at the connection between the equipment straight pipe and the end cover.

[0018] Working principle:

[0019] When discharging condensed water, the condensed water and steam in the pipeline are discharged into the connecting part through the straight discharge pipe of the equipment. Part of the steam will flow into the liquid accumulation cavity along the connecting pipe. During the flow, part of the steam condenses into liquid, and part of it enters the channel through the gap of the tooth-shaped part and contacts the accumulated water at the channel mouth. It is condensed into liquid by the accumulated water and concentrated in the liquid accumulation cavity. As the accumulated water in the liquid accumulation cavity increases, the liquid level rises. When it rises to the gap of the tooth-shaped part, it flows into the sewer from the connecting pipe along the gap.

[0020] When draining the water on the ground, it is only necessary to sweep the water on the ground into the liquid accumulation chamber. When the liquid level in the liquid accumulation chamber rises to the gap of the toothed part, it flows into the sewer along the gap from the connecting pipe.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] (1) The utility model provides a dual-purpose steam and water floor drain, in which steam and water have different inlets and are independent of each other, and can simultaneously drain condensed water and accumulate water on the floor.

[0023] (2) The liquid seal method can quickly condense the steam, forming an effective seal to prevent steam from overflowing. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-2 As shown, this embodiment provides a dual-purpose floor drain for steam and water, including: a connecting part 1, a liquid accumulation chamber 2 and an end cover 4. The end cover 4 is located at the top of the connecting part 1 and the liquid accumulation chamber 2, and a sealing gasket 43 is provided at the bottom thereof, which is used to seal the gap between the end cover 4 and the ground to ensure the sealing between the floor drain as a whole and the sewer. A detachable top plate 41 is provided on the end cover 4, and the top plate 41 is located directly above the liquid accumulation chamber 2. A plurality of water flow holes 42 are provided on the top plate 4, and the water accumulated on the ground can flow into the liquid accumulation chamber 2 through the water flow holes 42. The equipment straight discharge pipe 6 passes through the end cover 4 and then extends into the connecting part 1. A sealing ring 61 is provided at the connection between the equipment straight discharge pipe 6 and the end cover 4 to ensure the airtightness of the connecting part. The liquid accumulation chamber 2 is located on one side of the connecting part 1, and the bottom of the liquid accumulation chamber 2 is connected to the side wall of the connecting part 1 through the connecting pipe 3. The accumulated water can normally flow into the connecting part 1 through the connecting pipe 3 and enter the sewer.

[0034] A liquid seal assembly is provided inside the liquid accumulation chamber 2, and the liquid seal assembly includes: a toothed portion 31 and a sealing cover 5. The toothed portion 31 is located at the top of the connecting tube 3, and has the same diameter as the connecting tube 3, so that the connecting tube 3 extends into the liquid accumulation chamber 2 and forms a height difference with the bottom surface of the liquid accumulation chamber 2. The sealing cover 5 covers the upper part of the toothed portion 31, and its diameter is larger than the diameter of the connecting tube 3, so that a channel 51 is formed between the inner wall of the sealing cover 5 and the outer wall of the connecting tube 3. There is a certain height difference between the channel opening of the channel 51 and the bottom surface of the liquid accumulation chamber 2. When the liquid accumulation chamber 2 stores a certain amount of accumulated water, the channel opening of the channel 51 will be submerged, thereby forming a liquid seal.

[0035] Furthermore, the top of the sealing cover 5 is conical. When local water falls onto the sealing cover 5 , the water can be guided into the liquid accumulation chamber 2 through the inclined surface on the top of the sealing cover 5 to avoid water accumulation on the top of the sealing cover 5 .

[0036] like Figure 3As shown, when discharging condensed water, the condensed water and steam in the pipeline are discharged into the connecting part 1 through the equipment straight pipe 6, and part of the steam will flow along the connecting pipe 3 into the liquid accumulation chamber 2. During the flow, part of the steam condenses into liquid, and another part enters the channel 51 through the gap of the toothed part 31 and contacts with the accumulated water at the channel mouth, and is condensed into liquid by the accumulated water, and finally collected in the liquid accumulation chamber 2. Figure 4 As shown, as the amount of water accumulated in the liquid accumulation chamber 2 increases, the liquid level rises. When it rises to the gap of the toothed portion 31, it flows into the sewer from the connecting pipe 3 along the gap.

[0037] like Figure 5 As shown, when draining the water on the ground, similar to the steam reflux process, the water on the ground only needs to be swept into the liquid accumulation chamber 2. When the liquid level in the liquid accumulation chamber 2 rises to the gap of the toothed portion 31, it flows into the sewer along the gap from the connecting pipe 3. Note: The process of draining condensed water and draining the water on the ground can be carried out at the same time.

[0038] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
