Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air partitions, in particular to an air partition. Background Art
[0002] The existing air partition device structure is an integrated design, with a mirror observation window on the top to observe the internal situation. The height difference between the upstream and downstream is used to form an air partition. A check device is installed at the drainage end, and a partition is provided inside to form a water seal. The air partition device can be directly connected to the equipment and the sewer, and the water vapor is discharged into the device, and the steam and the discharged water will not spread into the environment.
[0003] Because it is a closed device, the pressure during pressurized drainage cannot be released in time, which will impact the discharge pipe and cause backflow of the floor drain at the adjacent drainage point. If it is high-temperature condensation, the large amount of heat released during discharge will heat the water in the sewage pipe. The water seal will bubble after being heated, which will also damage the clean area environment. Therefore, when using this method, it is necessary to consider the design of the water seal height of the adjacent drainage point, or the drainage point is discharged separately, which is difficult to design or has high manufacturing costs. Or it is necessary to install a heat exchanger to reduce the temperature of the condensed water with steam, which requires more cooling water (chilled water) or requires the installation of a heat exchanger with a larger heat exchange area, which has high manufacturing and operating costs.

[0027] Reference Figure 1 The utility model provides an air partition, including a partition body 100 and a water supply pipe 600, wherein a water inlet pipe 300 is arranged at one end of the partition body 100, and a water outlet pipe 400 is arranged at the other end, and the height of the water inlet pipe 300 is higher than that of the water outlet pipe 400;
[0028] The partition body 100 is provided with a partition cavity, and a partition plate 200 is provided in the partition cavity, and the partition plate 200 is located between the water inlet pipe 300 and the water outlet pipe 400, and the partition plate 200 divides the partition cavity into a front partition cavity and a rear partition cavity, the water inlet pipe 300 is connected to the front partition cavity, and the water outlet pipe 400 is connected to the rear partition cavity;
[0029] The upper end of the partition body 100 is provided with a mirror observation window 101, the lower end of the partition body 100 is provided with a lower bottom plate 102, and a lower channel is formed between the lower end of the partition plate 200 and the lower bottom plate 102;
[0030] One end of the water supply pipe 600 is connected to the mirror observation window 101 and communicated with the front partition cavity; a water supply valve 601 is provided on the water supply pipe 600 .
[0031] In some embodiments, one end of the partition body 100 of the air partition is connected to the water inlet pipe 300, and the other end is connected to the water outlet pipe 400; the water inlet pipe 300 and the water outlet pipe 400 are arranged at opposite ends of the partition body 100; the production equipment is connected to the water inlet pipe 300, and the wastewater discharged by the production equipment enters the air partition through the water inlet pipe 300. When the temperature of the wastewater is too high, tap water or water is added to the air partition through the water supply pipe 600. One end of the water supply pipe 600 is connected to the water supply system, such as the tap water network. The temperature of tap water is generally not high. After the tap water enters the air partition from the water supply pipe 600, it can reduce the temperature of the wastewater entering from the water inlet pipe 300, and appropriately reduce the temperature and pressure in the air partition; since the air partition has no outlet to the external environment, there is no need to worry about steam leakage, and the temperature does not need to be lowered too much.
[0032] In an optional embodiment, an air supply pipe 700 is further included, and the air supply pipe 700 is connected to the mirror observation window 101 and communicated with the front partition cavity. A non-return device 701 is provided on the air supply pipe 700.
[0033] When the pressure in the air partition is low, that is, the pressure in the air partition is lower than the external pressure, air is supplied to the front partition cavity through the air supply pipe 700; a check device 701 is provided on the air supply pipe 700, and the check device 701 is a prior art, so that external air can pass through the check device 701; when the pressure in the partition cavity is too high, the gas in the partition cavity cannot be discharged through the air supply pipe 700 due to the existence of the check device 701.
[0034] In an optional embodiment, a drain pipe 500 is provided on the lower base plate 102 , and a drain valve 501 is provided on the drain pipe 500 .
[0035] A mirror observation window 101 is provided at the upper end of the partition body 100, through which the condition of the partition body 100 can be observed, and a lower base plate 102 is provided at the lower end of the partition body 100, to which a drain pipe 500 is connected, and a drain valve 501 is provided on the drain pipe 500, which is generally in a closed state; when it is necessary to drain the waste water in the partition body 100, the drain valve 501 is opened so that the waste water in the partition body 100 can be discharged from the lowest drain pipe 500.
[0036] In an optional embodiment, an exhaust pipe 800 is further included, and the exhaust pipe 800 is connected to the mirror observation window 101 and communicated with the front partition cavity; a one-way valve 801 and an exhaust valve 802 are arranged on the exhaust pipe 800.
[0037] In some embodiments, an exhaust pipe 800 is further provided on the partition body 100, and the exhaust pipe 800 is connected to the front partition cavity. When the pressure in the partition cavity is too high, the exhaust valve 802 is opened to allow the gas in the partition cavity to be discharged through the exhaust pipe 800; the exhaust pipe 800 is connected to the exhaust system. In order to prevent the gas in the exhaust system from entering the partition cavity from the exhaust pipe 800, a one-way valve 801 is provided on the exhaust pipe 800. The one-way valve 801 allows the gas in the exhaust pipe 800 to flow in one direction only, that is, to be discharged from the partition cavity along the exhaust pipe 800 into the exhaust system.
[0038] Generally, when the drainage volume is small, you can first close the valve on the drain pipe, then open the exhaust valve on the exhaust pipe to discharge the gas in the partition cavity, then close the exhaust valve, and open the valve on the drain pipe. This can change the problem of small drainage volume in the drain pipe.
[0039] In an optional embodiment, a backflow prevention plate is provided at the water outlet end of the water inlet pipe 300 .
[0040] In an optional implementation, the upper end of the backflow prevention plate is hinged to the water outlet pipe 400 .
[0041] In some embodiments, in order to prevent the wastewater in the partition cavity from flowing back into the water inlet pipe 300, an anti-backflow plate is provided at the outlet end of the water inlet pipe 300, and the anti-backflow plate is hinged on the outlet pipe 400; when the water inlet pipe 300 discharges wastewater to the partition body 100, the wastewater can cause the anti-backflow plate to rotate, and then the wastewater can enter the partition body 100; when there is a lot of water in the partition body 100, the water causes the anti-backflow plate to block the water inlet pipe 300, so that water cannot enter the water inlet pipe 300, thereby realizing the anti-backflow function.
[0042] In an optional embodiment, an assembly groove is provided on the inner wall of the partition cavity, and the partition plate 200 is assembled on the assembly groove.
[0043] In an optional embodiment, the contact edge between the partition plate 200 and the inner wall of the partition cavity is provided with sealant.
[0044] In some embodiments, there is an assembly groove on the inner wall of the partition cavity, and the partition plate 200 is assembled in the assembly groove, so that the partition plate 200 is installed. In order to seal between the partition plate 200 and the partition cavity, the partition plate 200 has a sealant or a sealing rubber ring.
[0045] In an optional embodiment, the partition body 100 is cylindrical.
[0046] In some embodiments, the partition body 100 may be cylindrical or in other shapes.
[0047] In an optional implementation, the lower end of the water outlet pipe 400 is higher than the lower end of the partition plate 200 .
[0048] In some embodiments, the lower end of the outlet pipe 400 is higher than the lower end of the partition plate 200. In this way, after the wastewater enters the partition body 100, the wastewater can enter the drain pipe 500 only when the height of the wastewater is higher than the lower end of the partition plate 200. The wastewater can play a sealing role, preventing the gas in the rear partition cavity from entering the front partition cavity, thus forming an air partition.
[0049] The partition body 100 of the air partition provided by the utility model is connected to a water supply pipe 600, which is used to connect to the water supply system. Tap water is added to the front partition cavity through the water supply pipe 600 to reduce the temperature in the front partition cavity, thereby cooling the steam and appropriately reducing the temperature and pressure to avoid excessive pressure in the air partition, which may cause backflow of floor drains at adjacent drainage points.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
