Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an exhaust mechanism for a carbon dioxide compressor. Background Art

[0002] The compressor that produces liquid carbon dioxide compresses carbon dioxide (raw gas) and then sends the high-pressure gas to the condenser through the exhaust mechanism. The exhaust mechanism is long, and the raw gas inevitably contains about 3% moisture, so condensed water may be generated on the way. If left unchecked, the condensed water can enter the condenser and other components along with the gas, causing damage.

[0003] In order to avoid the above problems, in view of this: Chinese patent CN209855997U discloses a carbon dioxide compressor exhaust mechanism; a drain pipe is welded at the bottom end of the exhaust pipe, and the drain pipe is connected with a liquid storage tank, the liquid storage tank is a stainless steel tank, and an arc dome is arranged on the top of the liquid storage tank, and a liquid inlet pipe is welded on the top of the arc dome, and the liquid inlet pipe is connected with the drain pipe, and a drain pipe is inserted into the side wall of the liquid storage tank, and a shower valve is installed at the end of the drain pipe; the condensed water in the exhaust pipe is diverted to the liquid storage tank for temporary storage, and discharged by certain means, which can effectively reduce the amount of water accumulated in the exhaust pipe, thereby reducing damage to equipment such as the exhaust pipe and the condenser.

[0004] Although the above has achieved the goal of reducing the amount of water accumulation in the exhaust pipe, it is inevitable that there are still some shortcomings in its actual use. For example, the device lacks a flexible sealing mechanism, which leads to the problem of gas being discharged when the accumulated water in the exhaust pipe is discharged. In order to avoid such problems, a carbon dioxide compressor exhaust mechanism is proposed to solve the existing problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a carbon dioxide compressor exhaust mechanism, which solves the problem that the device lacks a flexible sealing mechanism, thereby causing gas to be discharged when the exhaust pipe discharges accumulated water.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a carbon dioxide compressor exhaust mechanism, including an exhaust pipe and a confluence tank, the confluence tank is arranged at the bottom of the exhaust pipe, the top of the confluence tank is connected to a confluence pipe, and a plurality of confluence tanks are arranged between the confluence pipe and the exhaust pipe, the inner wall of the confluence tank is fixedly connected to a sealing ring, the inner wall of the confluence tank is fixedly connected to a sleeve through a bracket, the interior of the sleeve is slidably connected to a telescopic rod, and the bottom end of the telescopic rod is fixedly connected to a sealing plate used in conjunction with the sealing ring, and a reset spring is fixedly connected between the telescopic rod and the sleeve.

[0007] Preferably, the bottom of the exhaust pipe is connected to a pipe end matched with the gathering tank, and the surface of the pipe end and the top of the gathering tank are fixedly connected with a first flange, and the two first flanges are fixedly connected together by a plurality of first bolts.

[0008] Preferably, the top of the collecting pipe is connected to a plurality of transfer pipes used in conjunction with the collecting tank, and the surface of the transfer pipe and the bottom of the collecting tank are fixedly connected with a second flange, and the two second flanges are fixedly connected together by a plurality of second bolts.

[0009] Preferably, a filter plate is fixedly provided on the top of the sleeve and inside the convergence tank.

[0010] Preferably, one side of the manifold is connected to a discharge pipe.

[0011] Preferably, a window is fixedly provided on the front side of the manifold tank via a groove.

[0012] Beneficial Effects

[0013] The utility model provides a carbon dioxide compressor exhaust mechanism. Compared with the existing technology, the utility model has the following beneficial effects: by arranging a convergence tank between the exhaust pipe, the confluence tank and the collection pipe, and elastically arranging a sealing plate and fixedly arranging a sealing ring inside the convergence tank, the convergence tank can intermittently discharge the accumulated water through the elastic sealing cooperation of the sealing plate and the sealing ring, avoiding the problem that the gas and accumulated water will enter the confluence tank together due to the lack of sealing cooperation between the exhaust pipe and the collection pipe, and secondly, by connecting the confluence tank, the pipe end and the transfer pipe in sections, the convergence tank can be easily removed and replaced separately.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a carbon dioxide compressor exhaust mechanism, including an exhaust pipe 1 and a manifold 2, the manifold 2 is arranged at the bottom of the exhaust pipe 1, one side of the manifold 2 is connected to a discharge pipe 17, and a window 18 is fixedly arranged on the front side of the manifold 2 through a groove.

[0022] Furthermore, in order to avoid the discharge of gas when the accumulated water is discharged, the top of the collection tank 2 is connected to the collection pipe 3, and a number of collection tanks 4 are arranged between the collection pipe 3 and the exhaust pipe 1, and the inner wall of the collection tank 4 is fixedly connected to a sealing ring 5, and the inner wall of the collection tank 4 is fixedly connected to a sleeve 6 through a bracket, and the interior of the sleeve 6 is slidably connected to a telescopic rod 7, and the bottom end of the telescopic rod 7 is fixedly connected to a sealing plate 8 used in conjunction with the sealing ring 5, and a reset spring 9 is fixedly connected between the telescopic rod 7 and the sleeve 6, and a filter plate 16 is fixedly arranged on the top of the sleeve 6 and inside the collection tank 4.

[0023] Among them, in order to facilitate the removal and replacement of the gathering tank 4, the bottom of the exhaust pipe 1 is connected to a pipe end 10 used in conjunction with the gathering tank 4, and the surface of the pipe end 10 and the top of the gathering tank 4 are fixedly connected with a first flange 11, and the two first flanges 11 are fixedly connected together by a plurality of first bolts 12. The top of the collecting pipe 3 is connected to a plurality of transfer pipes 13 used in conjunction with the gathering tank 4, and the surface of the transfer pipe 13 and the bottom of the gathering tank 4 are fixedly connected with a second flange 14, and the two second flanges 14 are fixedly connected together by a plurality of second bolts 15.

[0024] During use, when the exhaust pipe 1 is conveying gas, local water condensate in the gas will accumulate on the inner wall of the exhaust pipe 1 and gradually gather inside the gathering tank 4. During the process of water gathering inside the gathering tank 4, the water will continuously exert pressure on the sealing plate 8 until the sealing plate 8 is forced to move downward and cooperate with the sealing ring 5 to seal. After the sealing plate 8 and the sealing ring 5 are staggered, the water source flows along the gathering tank 4 and the gathering pipe 3 to the inside of the confluence tank 2. When the weight of the water source does not meet the downward pressure condition, the sealing plate 8 and the sealing ring 5 continue to maintain an elastic and airtight fit to prevent gas from passing into the interior of the confluence tank 2.
