Description

Technical Field

[0001] This utility model relates to the field of dental comprehensive treatment machine technology, and in particular to a water circulation device in natural gas production. Background Technology

[0002] Natural gas has advantages such as being clean and having a stable supply. It is widely used in residents' daily lives, such as cooking and heating, providing them with convenient and comfortable living conditions. It is also an important chemical raw material, used to produce chemicals such as synthetic ammonia, methanol, formaldehyde, and acetic acid, as well as various polymer materials. Its applications are extensive.

[0003] In the natural gas production process, there are technical aspects that require cooling. For example, during the gathering and transportation of natural gas, the temperature of the natural gas needs to be controlled to prevent the formation of hydrates. However, since natural gas is transported in pipelines, the means of cooling are relatively limited, making it difficult to effectively cool the natural gas during transportation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water circulation device for natural gas production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water circulation device for natural gas production includes a chiller, an installation pipe fixed to the bottom of the chiller, a spiral conveying pipe installed inside the installation pipe, a stirring rod installed inside the installation pipe at the spiral center of the spiral conveying pipe, and a drive component for operating the stirring rod installed at the bottom of the chiller.

[0007] A return pipe is fixed to one end of the spiral conveying pipe, a water pump is fixed to the outer wall of the chiller, the water outlet of the water pump is fixed to the water inlet of the chiller, the water inlet of the water pump is fixed to the return pipe, and the water outlet of the chiller is fixedly connected to the installation pipe through a connecting pipe.

[0008] Preferably, the driving component includes a drive motor fixed to the bottom of the chiller, a first synchronous pulley fixed to the output end of the drive motor, a second synchronous pulley connected to the first synchronous pulley via a synchronous belt, the second synchronous pulley being coaxially fixed with the stirring rod, and a hole for the shaft to pass through being opened on the end face of the mounting tube.

[0009] Preferably, one end of the mounting tube has a hole for the spiral conveying tube to pass through, the other end of the spiral conveying tube is fixed with a connecting pipe, and the outer wall of the mounting tube has a hole for the connecting pipe to pass through.

[0010] Preferably, two mounting brackets are fixed on one side of the bottom of the chiller, and the mounting pipe is fixed to the mounting brackets.

[0011] Preferably, a U-shaped bracket is fixed to the bottom of the chiller on the side corresponding to the fixed frame.

[0012] Preferably, a fixing sleeve is fixedly fitted on the outer wall of the stirring rod near the connecting pipe. Two symmetrical connecting arms are fixed on the outer wall of the fixing sleeve. A round rod is fixed on the connecting arm, and a scraper that is tightly attached to the inner wall of the mounting pipe is fixed on the outer wall of the round rod.

[0013] Preferably, a manual valve connected to one end of the installation pipe is installed.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Because it employs a chiller, installation pipe, spiral conveying pipe, stirring rod, and drive unit, water is supplied to the installation pipe by the chiller and circulated by a water pump. Natural gas flows into the spiral conveying pipe through a connecting pipe. Since the spiral conveying pipe is immersed in the water-filled installation pipe, it can transfer cold to the natural gas, causing the natural gas to cool down rapidly. The water circulates between the chiller and the installation pipe, ensuring water uniformity. The drive motor drives the first synchronous wheel to rotate, and under the action of the synchronous belt, the second synchronous wheel drives the stirring rod inside the installation pipe to stir and mix the water. This effectively solves the problems mentioned in the background technology, ensures water uniformity, promotes water temperature uniformity, and facilitates natural gas cooling, achieving cooling treatment while transporting the natural gas.

[0016] 2. A connecting arm with a fixed sleeve is provided, and a round rod is installed on the connecting arm. A scraper is fixed on the outer wall of the round rod. Through the above design, when the fixed sleeve rotates with the stirring rod, the scraper plays a role in mixing evenly on the one hand, and on the other hand, it can scrape the inner wall of the installation pipe to prevent the inner wall of the installation pipe from having problems such as scale and debris due to long-term accumulation, thus playing a cleaning role.
