Description

Technical Field

[0001] This invention belongs to the field of pipeline cleaning, and specifically relates to a solid-liquid-gas separation pipeline cleaning device. Background Technology

[0002] When using long-distance pipelines to transport liquids, marine organisms, silt, and domestic waste can easily accumulate on the inner walls of the pipeline after prolonged use, causing the inner diameter to decrease and affecting flow rate and volume, resulting in poor transportation efficiency. Due to the excessive length of the pipeline, debris accumulates inside, generating many harmful gases that cannot be manually cleaned. Gas-liquid pulse cleaning is generally used, and after gas-liquid pulse cleaning, it is necessary to separate the gas, liquid, and solid debris.

[0003] Invention patent CN214714875U discloses a gas-liquid-solid separator for water pipeline engineering. "The inlet pipe extends upwards into the separator cylinder and reaches above the support plate. This pipe uses a certain radius of curvature to guide the flow, ensuring that the gas-liquid-solid mixture flows uniformly to the upper space of the separator. The support plate is located at the top of the separator cylinder and is covered with a filter screen for initial separation of gas, solid, and liquid. Gas accumulates in the upper space of the support plate and is eventually automatically discharged through the top exhaust port, while large solid particles remain above the support plate and are removed through a hand hole. A semi-circular filter is provided at the front end of the outlet pipe to trap fine particles." Solid matter is prevented from entering the outlet pipe; the drain port is located at the bottom of the separator to remove fine solid impurities deposited by the device. This separator can separate gas and solid impurities in the pipeline. However, according to paragraph 0006 of the instruction manual, "the support plate is used to initially separate gas-solid and liquid, so that the gas accumulates in the upper space and is eventually automatically discharged through the top exhaust port, while large solid particles remain above the separation net and are removed through the hand hole." This patent cannot separate large solid particles and small solid particles together, and the separation of gas relies entirely on the buoyancy of the gas itself. Therefore, it must be set at a high position to separate the gas. Summary of the Invention

[0004] To address the above problems, the present invention provides a solid-liquid-gas separation pipeline cleaning device.

[0005] The object of this invention is achieved in the following manner: A solid-liquid-gas separation pipeline cleaning device includes a tank, an inlet pipe extending into the tank, a primary debris separation screen below the inlet pipe, a conveying chamber below the primary debris separation screen, a spiral conveying rod with spiral blades inside the conveying chamber, a gas filter above the inlet pipe, and a gas outlet above the gas filter, a liquid outlet below the conveying chamber near the primary debris separation screen, and a solid outlet below the conveying chamber away from the primary debris separation screen, with the spiral blades on both sides of the solid outlet symmetrically arranged in the spiral direction, and a secondary debris separation screen between the liquid outlet and the conveying chamber.

[0006] The solid-liquid-gas separation pipeline cleaning device has a bottom arc-shaped conveying chamber, and the axial direction of the spiral conveying rod is coaxial with the arc-shaped bottom of the conveying chamber.

[0007] The solid-liquid-gas separation pipeline cleaning device is described above, wherein the conveying chamber and the spiral conveying rod are inclined, with the side closer to the secondary separation net of debris being lower in height and the side farther away from the secondary separation net of debris being higher in height, and the spiral blades are fitted with a clearance fit to the bottom of the conveying chamber.

[0008] The solid-liquid-gas separation pipeline cleaning device includes a gas filtration device comprising a collecting chamber, a filter disposed below the collecting chamber, and a primary liquid baffle and a secondary liquid baffle disposed within the collecting chamber.

[0009] The solid-liquid-gas separation pipeline cleaning device mentioned above includes an exhaust fan installed between the gas outlet and the gas filter device.

[0010] The solid-liquid-gas separation pipeline cleaning device has a solid storage tank installed below the solid discharge port.

[0011] The solid storage tank in the solid-liquid-gas separation pipeline cleaning device is detachable.

[0012] The solid-liquid-gas separation pipeline cleaning device has an inlet control valve installed on the part of the inlet pipe located outside the tank.

[0014] Figure 1 This is a schematic diagram of the present invention; Figure 2 This is a side sectional view of the conveyor compartment. Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1-2 As shown, a solid-liquid-gas separation pipeline cleaning device includes a tank 1 with an inlet pipe 11. The device is characterized in that: the inlet pipe 11 extends into the tank; a primary debris separation net 21 is installed below the inlet of the inlet pipe 11; a conveying chamber 3 is installed below the primary debris separation net; a spiral conveying rod 31 is installed inside the conveying chamber 3, and spiral blades 32 are installed on the spiral conveying rod; a gas filter 4 is installed above the inlet pipe 11, and a gas outlet 12 is installed above the gas filter 4; a liquid outlet 13 is installed below the conveying chamber 3 on the side near the primary debris separation net 21, and a solid outlet 14 is installed below the conveying chamber on the side away from the primary debris separation net 21; the spiral blades 32 on both sides of the solid outlet 14 are symmetrically arranged in the spiral direction; a secondary debris separation net 22 is installed between the liquid outlet 13 and the conveying chamber 3.

[0017] The mixture in the pipeline enters the tank 1 through the inlet pipe 11. The gas moves upward, filtering out solids and liquids, and then exits from the gas outlet 12. The liquid and solids move downward. The liquid passes through the primary impurity separation screen 21 and the secondary impurity separation screen 22 before exiting from the liquid outlet pipe. The solids enter the transport chamber 3. Driven by the spiral blades, the solids move from the side of the secondary impurity separation screen to the side of the solids outlet in the transport chamber 3 and are then discharged from the solids outlet. The spiral blades on both sides of the solids outlet are symmetrically arranged in the spiral direction. When the spiral conveyor rotates, the impurities on the left side of the solids outlet move to the right, and the impurities on the right side of the solids outlet move to the left. This facilitates the discharge of solid impurities and prevents solids from accumulating on the left side of the solids outlet, which could damage the bearings or other parts.

[0018] like Figure 2 As shown, in the solid-liquid-gas separation pipeline cleaning device, the bottom of the conveying chamber 3 is arc-shaped, and the axial direction of the spiral conveying rod 31 is coaxial with the arc-shaped bottom of the conveying chamber 3. The arc-shaped bottom of the conveying chamber 3 allows for better matching between the circular spiral blades 32 and the conveying chamber, reducing the areas that the blades cannot reach during rotational conveying.

[0019] In the solid-liquid-gas separation pipeline cleaning device, the conveying chamber (3) and the spiral conveying rod (31) are inclined. The side closer to the secondary separation net (22) is lower in height, while the side farther from the secondary separation net (22) is higher. The spiral blade 32 is fitted with a gap between itself and the bottom of the conveying chamber 3. The inclined arrangement of the bottom of the conveying chamber (3) and the spiral conveying rod allows the liquid to move to the lower side through the gap between the spiral blade and the bottom of the chamber, and then be discharged from the liquid outlet after secondary separation. Meanwhile, solid debris is pushed to the higher side by the spiral blade and then discharged from the solid outlet, thus achieving solid-liquid separation.

[0020] The solid-liquid-gas separation pipeline cleaning device includes a gas filtration device (4) comprising a collecting chamber (41), a filter screen (42) disposed below the collecting chamber (41), and a primary liquid baffle (411) and a secondary liquid baffle (412) disposed within the collecting chamber (41). The filter screen 42 is used to filter the solids in the mixture, allowing only gas and a small amount of liquid to enter the collecting chamber; the primary liquid baffle 411 and the secondary liquid baffle 412 are used to filter the liquid in the gas. The baffles are inclined downwards, so when the gas rises, it can change direction after encountering the baffle and continue to rise from below, while the liquid encounters the baffle and gathers into a water flow, dripping from the inclined baffle. This ensures that only the gas is allowed to pass through the exhaust fan and then discharged through the gas outlet.

[0021] The solid-liquid-gas separation pipeline cleaning device described above includes an exhaust fan (5) installed between the gas outlet (12) and the gas filter (3). The motor drives the exhaust fan to rotate, causing the gas to be discharged from the gas outlet pipe 12, which can increase the gas-liquid separation speed and improve the separation efficiency. At the same time, since the exhaust fan provides the power for the gas to be discharged, the gas is not only discharged by buoyancy, so there are no requirements for the installation position of the cleaning device, and it is not required to be installed at a high place.

[0022] The solid-liquid-gas separation pipeline cleaning device is provided with a solid storage tank (141) below the solid discharge port (14).

[0023] The solid-liquid-gas separation pipeline cleaning device described above has a detachable solid storage tank (141). The solid storage tank facilitates the unified handling of solid debris; the detachable solid storage tank allows for complete replacement of the entire tank when it is full, resulting in higher efficiency.

[0024] The solid-liquid-gas separation pipeline cleaning device has an inlet control valve (111) installed on the part of the inlet pipe (11) located outside the tank body (1). When the solid storage tank is full and needs to be cleaned, the inlet control valve can be closed, the solid storage tank can be cleaned, and then the valve can be reopened.

[0025] The specific working process of this invention is as follows: like Figure 1As shown, the material to be separated, ejected by the gas-liquid pulse in the pipeline to be cleaned, enters the solid-liquid-gas impurity separation and cleaning device through the liquid inlet. The gas moves upward, passes through the chamber filter screen, and enters the collecting chamber, while the solids are filtered out of the chamber. The first-stage and second-stage liquid baffles filter out the moisture mixed in the gas, and the motor drives the exhaust fan, which discharges the gas from the gas outlet.

[0026] The liquid and solid move downwards, first contacting the primary separation screen. The solid is blocked outside the primary separation screen, while the liquid passes through the primary separation screen and then flows to the right side of the transport chamber, through the secondary separation screen, and finally discharged from the liquid outlet.

[0027] Solids and residual liquids enter the transport chamber from the left side of the primary separation screen and move towards the solids discharge outlet under the action of the screw conveyor. Due to the inclined arrangement of the screw conveyor and the bottom of the transport chamber, the secondary separation screen is lower on one side and the solids discharge outlet is higher on the other. Liquids flow from high to low. Therefore, after solid debris and residual liquids enter the transport chamber, the solid debris is transported to the left by the screw conveyor to the solids discharge outlet and discharged into the solids storage tank. The liquid flows to the lower right side, passes through the secondary separation screen, and is discharged from the liquids discharge outlet.

[0028] The spiral blades on both sides of the solid discharge port are symmetrically arranged. When the spiral conveyor rotates, the solids on both sides of the solid discharge port move towards the solid discharge port, preventing solids from accumulating on one side. After the solid storage tank is full, close the liquid inlet control valve, remove the solid storage tank, replace it with an empty solid storage tank, and then open the liquid inlet control valve to continue operation.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be considered within the scope of protection of the present invention.
