Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary devices for oil refining and chemical industry, and relates to a floor drain plugging device for petrochemical pipe networks. The present invention also relates to a method for plugging floor drains in petrochemical pipe networks. Background Art

[0002] In petrochemical enterprises, in order to meet operations such as sampling, discharging, purging, and draining liquid, manual valves are set in the process pipelines to discharge corresponding materials. To avoid environmental pollution caused by discharged sewage and waste oil, underground pipelines are built in petrochemical plants to collect and uniformly treat the discharged waste oil and wastewater. However, the waste oil and wastewater cannot be discharged in a sealed manner, resulting in volatile components in the wastewater and waste oil entering the atmosphere, causing environmental pollution. At the same time, the substances remaining at the discharge funnels of wastewater and waste oil are flammable and explosive, which also increases the risk points for on-site hot work in petrochemical plants. The connection between the waste oil and wastewater funnels and the underground sewage and oil storage tanks, problems such as material volatilization and leakage or cross-flow of underground pipeline media have become potential risk points. To avoid cross-flow of underground pipeline media, petrochemical enterprises set liquid level displays for underground storage tanks and timely send out materials when the liquid level in the storage tank is high. Soft plugs with appropriate sizes are customized for the discharge funnels, and the funnels are blocked in a timely manner after sampling, dehydration, and purging to prevent the volatilization of volatile components in the wastewater and waste oil. At the same time, it also reduces the risk points for on-site hot work in petrochemical plants. However, the discharge funnels of petrochemical plants cannot be completely sealed with soft plugs. To prevent splashing, some drain pipes are inserted into the drain funnels, which also makes it impossible to seal the drain funnel openings with soft plugs. Therefore, there is an urgent need to design a floor drain plugging device for petrochemical pipe networks. Summary of the Invention

[0003] The purpose of the present invention is to provide a floor drain plugging device for petrochemical pipe networks, which solves the problem of environmental pollution caused by the volatilization of components in wastewater and waste oil in pipelines in the prior art.

[0004] Another purpose of the present invention is to provide a method for plugging floor drains in petrochemical pipe networks, which solves the problem of leakage of volatile components in wastewater and waste oil in the prior art.

[0005] The technical solution adopted by the present invention is that the floor drain plugging device for petrochemical pipe networks includes a floor drain funnel. Through holes symmetrically arranged along the center line are provided on the side wall of the floor drain funnel. A plugging pipe assembly is sleeved through the through holes of the floor drain funnel. One end of the plugging pipe assembly is connected with an inflation assembly, and the other end is threadedly connected with a nut.

[0006] The characteristics of the present invention also lie in that:

[0007] The plugging pipe assembly includes a hollow pipe. A rubber balloon is sleeved outside the hollow pipe. Threads are provided on the outer surfaces of both ends of the hollow pipe. One end of the hollow pipe is connected with the inflation assembly.

[0008] The inflating assembly includes a valve core, a threaded buckle is fixedly connected to the valve core, and the threaded buckle is threadedly connected to the hollow tube.

[0009] A number of air holes are provided on the side wall of the hollow tube.

[0010] Another technical solution adopted by the present invention is a method for plugging floor drains in a petrochemical pipe network, which is specifically implemented according to the following steps:

[0011] Step 1: A through hole is opened on the side wall of the floor drain funnel, a rubber balloon is sleeved on the hollow tube, and the hollow tube sleeved with the rubber balloon is passed through the through hole of the floor drain funnel;

[0012] Step 2: The valve core is inserted into one end of the hollow tube, the valve core is fixed using a threaded buckle, and the other end of the hollow tube is fixed by screwing on a nut;

[0013] Step 3: Gas is blown into the hollow tube through the valve core, and the gas passes through a number of air holes provided in the hollow tube to continuously inflate the rubber balloon until it finally fits to the inner diameter edge of the floor drain funnel, completing the plugging of the floor drain.

[0014] The beneficial effects of the present invention are: The floor drain plugging device for a petrochemical pipe network of the present invention realizes that during normal operations such as liquid drainage and medium discharge, the staff can tightly plug during sampling, dehydration, and purging by inflating or deflating the gas, avoiding the leakage of volatile components in waste water and waste oil. At the same time, during sampling, dehydration, and purging operations, the floor drain opening can be kept unobstructed. Description of the Drawings

[0018] The present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0019] The floor drain plugging device for a petrochemical pipe network of the present invention, as Figure 1As shown in the figure, it includes a floor drain funnel 1. Through holes symmetrically arranged along the center line are provided on the side wall of the floor drain funnel 1. The positions of the through holes provided on the side wall of the floor drain funnel 1 avoid the pipelines inserted into the floor drain bell mouth. A plugging pipe assembly 2 is sleeved through the through holes of the floor drain funnel 1. One end of the plugging pipe assembly 2 is connected to an inflation assembly 3, and the other end is a closed end. The plugging pipe assembly 2 includes a rubber balloon 203 sleeved on the outside. The rubber balloon 203 is made of a corrosion-resistant and high-temperature aging-resistant material. Threads are provided on the outer surfaces at both ends. One end is connected to the inflation assembly 3. The inflation assembly 3 includes a valve core 301. The valve core 301 is fixedly connected with a threaded buckle 302. The threaded buckle 302 is threadedly connected. A number of air holes 202 are provided on the side wall. The rubber balloon 203 is inflated through the air holes, so that the rubber balloon 203 continuously expands. Eventually, the rubber balloon 203 fits against the inner wall of the floor drain funnel 1, achieving the prevention of hydrocarbon volatilization in the floor drain and the prevention of external media from entering the floor drain. A nut 4 is also threadedly connected. The nut 4 is used to fix the floor drain funnel 1.

[0020] The method for plugging the floor drain of the petrochemical pipe network is specifically implemented according to the following steps:

[0021] Step 1: Open through holes on the side wall of the floor drain funnel 1, sleeve the rubber balloon 203 on it, and pass the one sleeved with the rubber balloon 203 through the through holes of the floor drain funnel 1;

[0022] Step 2: Insert one end of the valve core 301, and use the threaded buckle 302 to fix the valve core 301. The other end is tightened and fixed with a nut 4;

[0023] Step 3: Blow air into the valve core 301. The air causes the rubber balloon 203 to continuously expand through a number of air holes 202 provided, and finally fits against the inner diameter edge of the floor drain funnel 1 to complete the plugging of the floor drain.

[0024] The method for plugging floor drains in petrochemical pipe networks of the present invention has the following working principle. Drill holes in the side wall of the floor drain funnel 1 near the ground end so that the plugging pipe assembly 2 passes through the floor drain funnel 1. The drilling position avoids the pipeline inserted into the floor drain bell mouth. Air holes 202 are evenly arranged on it to ensure that the inside and outside of the hollow pipe 201 are connected. One end of the hollow pipe 201 is plugged, and the other end of the hollow pipe 201 is connected to the valve core 301. The rubber balloon 203 made of corrosion-resistant and high-temperature aging-resistant material is fixed at both ends of the hollow pipe 201 so that the width of its fixed end is close to the width of the floor drain funnel 1. After passing through the eyelet at the ground end of the floor drain funnel 1, it is fixed through the threaded buckle 302 in the inflation assembly 3, and the sealing end is tightened and fixed with the nut 4. To ensure the tightness of the floor drain, air is blown into the hollow pipe 201 through the valve core 301, and the air in the hollow pipe 201 causes the rubber balloon 203 to continuously expand through the air holes, and finally fits to the inner diameter edge of the floor drain, preventing the volatilization of hydrocarbons in the floor drain and at the same time preventing external media from entering the floor drain. When sampling, purging, or replacing is required, hold down the valve core 301 so that the gas in the rubber balloon is discharged through the hollow pipe 201, and the floor drain can perform normal liquid drainage, medium discharge and other operations. After the operation is completed, gas is blown in again to seal the floor drain.
