Description

Technical Field

[0001] The present invention is a pollution spiral flow cleaning device and method, which relates to a cleaning method, and specifically to the cleaning of a sewer pipe when it is blocked, which facilitates people's life and production, and belongs to the field of cleaning technology. Background Art

[0002] With the continuous development of the modern economy, sewer pipes are widely used in people's daily production and life, and are used to remove debris, sewage, etc. Self-built houses in rural areas pay more attention to beauty on the basis of sheltering from wind and rain, and many families choose to bury concealed pipes. However, sewer pipes are easily blocked during use, and they need to be cleaned and unblocked regularly. For sewer pipes that are difficult to disassemble, cleaning becomes very difficult, and if the sewer pipes are damaged, the replacement cost will increase greatly. At present, there are three main ways of cleaning: one is to use mechanical vibration; one is a pipe dredging agent. The commonly used pipe dredging agents on the market are mainly corrosive chemicals, and their main components are strong corrosive chemicals such as hydroxides, carbonates, and sodium hypochlorite; and another is a pipe loosening machine, which uses instantaneous high pressure to push the blockage. These methods all have problems to varying degrees: during the cleaning process, irreversible damage to the pipeline; pollution to the entire pipeline and ecological environment, and also increase the difficulty of subsequent sewage treatment; cause sewage splashing, etc. Therefore, the best solution is to invent a fouling spiral flow cleaning (device) method to collect the blockages, which can not only dredge the pipeline but also minimize the damage to the pipeline. Summary of the invention

[0006] Preferably, the device is further provided with a spiral conduit, a water injection pipeline is provided in the positioning block, the ends of the water inlet hard pipe and the ends of the spiral conduit are respectively sealed and connected to the two ends of the water injection pipeline, and the spiral flow water injection nozzle is installed at the end of the spiral conduit.

[0007] Preferably, the cross section of the positioning block is in a quarter-circular shape, the arcuate surface of the positioning block contacts the inner wall of the pipe to be cleaned, and positioning springs are respectively provided between the other two side surfaces and the inner wall of the pipe to be cleaned.

[0008] Preferably, a positioning guide rail is provided in the positioning spring, a limit platform is provided at one end of the positioning guide rail, and the other end is slidably placed in the positioning adjustment groove on the guide block, and the two ends of the positioning spring are respectively located between the limit platform and the positioning adjustment groove opening of the corresponding positioning guide rail.

[0009] Preferably, a heater is provided in the water collecting tank.

[0010] Preferably, the device is also provided with an obstruction collection mechanism, which includes a water outlet hard pipe and a water outlet hose. One end of the water outlet hard pipe is a bell mouth, which is placed in the pipe to be cleaned, and the other end is connected to one end of the water outlet hose after passing through a rubber locking mouth. The other end of the water outlet hose is fixed in the water collecting tank by a round pipe fixing buckle.

[0011] Preferably, the rubber locking port is provided with anti-slip fixing buckles at the connection places with the water inlet hard pipe and the water outlet hard pipe respectively.

[0012] Preferably, a trash screen is provided in the water collecting tank to divide the water collecting tank into a water inlet area and a water outlet area.

[0013] Preferably, the spiral conduit is formed by bending an aluminum tube into a spiral shape, or by bending a hose wrapped with a steel wire into a spiral shape, which is convenient for shaping.

[0014] A second object of the present invention is to provide a method for cleaning a fouling spiral flow, which is characterized in that it comprises the following steps:

[0015] 1) When the pipeline is blocked, install the spiral outflow nozzle at the end of the spiral conduit, install the other end of the spiral conduit at the bottom of the water injection pipeline of the positioning block, and install the water inlet hard pipe at the top of the water injection pipeline;

[0016] 2) Place the water inlet and outlet pipes in the pipe to be cleaned, so that the spiral guide tube is close to the inner wall of the pipe to be cleaned; the two positioning springs of the positioning block make the arc surface of the positioning block close to the inner wall of the pipe to be cleaned; buckle the rubber locking mouth of the water inlet and outlet pipes, and use anti-slip fixing buckles to control the depth of the pipe before fixing;

[0017] 3) Fill the water collection tank with water and turn on the heater to heat it. Use a high-pressure injection pump to allow water to flow through the water inlet hose, water inlet hard pipe, water injection pipeline, and spiral conduit, and then flow out through the spiral outflow nozzle, forming a spiral flow in the pipe to be cleaned, stirring the obstruction and clearing the pipe.

[0018] 4) When some of the obstructions are cleared, the anti-slip fixing buckle can be opened, and the positioning block, spiral conduit, and spiral outflow nozzle can be moved downward in conjunction with the water inlet hard pipe to reduce the gap in the obstructed pipe and ensure the strength of the spiral flow;

[0019] 5) Due to the blockage of the pipeline itself, the dispersed blockage floats up, is collected by the outlet hard pipe, and is collected into the water collecting tank through the outlet hose.

[0020] The present invention has four parts:

[0021] 1. The first part is the water injection equipment, which uses a high-pressure injection pump to continuously inject water into the pipeline, so that the continuous water pressure continuously impacts the obstruction in the pipe wall;

[0022] 2. The second part is the injection tube, which uses a spiral conduit that is close to the pipe wall, can bend to different arcs, but can maintain a certain strength. The spiral conduit can be adjusted to adapt to pipes of different diameters. In pipes of the same diameter, the water outlet can also be adjusted to form different inclination angles;

[0023] For different oil stains and particles, different inclination angles can achieve different cleaning effects, generally between 45° and 75°; when the cleaning effect is not obvious, adjust the inclination angle to achieve better cleaning effect, which can efficiently generate continuous high-speed and high-pressure spiral flow;

[0024] 3. The third part is the positioning block on the inner wall of the pipe. The small hole is reserved for the injection tube to pass through the pipe to be cleaned to inject water. The positioning block can move up and down in the pipe to ensure the strength of the spiral flow.

[0025] 4. The fourth part is the water collection tank, which stores water and collects, filters and recycles the sewage cleaned out of the pipe.

[0026] The present invention is energy-saving and environmentally friendly, convenient to control and simple to operate. Specifically, it has the following advantages:

[0027] (1) It breaks away from the limitations of traditional cleaning methods (such as caustic soda dredging, disassembly and cleaning) and uses a new flow-generating device to form a high-speed and high-pressure spiral flow in the blocked sewer pipe, thereby solving the blockage of the sewer pipe;

[0028] (2) It can not only dredge the pipeline, but also collect the obstructions, realizing the integration of cleaning and collection of obstructions for reuse, thus minimizing the secondary pollution of the environment caused by the cleaning work and reducing the possibility of secondary obstruction of the pipeline;

[0029] (3) It will not cause physical damage to the original pipeline, nor will it produce chemical pollution, and the device can be used flexibly multiple times;

[0030] (4) It is suitable for pipes of different diameters, has strong adaptability and is easy to disassemble and install. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The dirt spiral flow cleaning device is as follows: Figure 1 , 2 shown.

[0036] Figure 1 The figure shows a cross-sectional view of the fouling spiral flow cleaning device. When the pipeline is blocked, the spiral guide tube 14, the positioning block 18, the water inlet hard pipe 8, the water outlet hard pipe 13, etc., which are close to the pipe wall and can be bent to different arcs but can maintain a certain strength, are inserted into the pipeline to be cleaned; the rubber locking mouth 12 is buckled, and the anti-slip fixing buckle 7 is used to control the penetration depth of the pipeline and then fixed.

[0037] Pour water into the water collecting tank 5, turn on the continuous heater 2 and the high-pressure injection pump 3, and the water flows through the water inlet hose 1 between the high-pressure injection pump and the water inlet hard pipe, the water inlet hard pipe 8, the water injection pipeline 9, and the spiral conduit 14 which is close to the pipe wall and can be bent to different arcs but can maintain a certain strength, and then flows out through the spiral outflow nozzle 10. When the injection intensity reaches a certain condition, a spiral flow can be formed in the sewer pipe to stir the blockage and dredge and clean the pipe.

[0038] When some of the obstructions are cleared, the water inlet hard pipe 8 can be cooperated to move the positioning block 18, the spiral guide tube 14, and the spiral flow outlet nozzle 10 downward, so that the gap in the blocked pipeline is reduced, thereby ensuring the strength of the spiral flow.

[0039] Since the sewer pipe itself is blocked, the blocked objects are floated up, collected by the outlet pipe 13, and then collected into the water collecting tank 5 through the outlet hose 11 connecting the outlet pipe and the water collecting tank (after continuously injecting water into the sewer pipe, if the pipe is not unblocked, the blocked objects can be discharged from the outlet pipe, and if the pipe is unblocked, they can be discharged from the sewer pipe) to prevent secondary blockage. The outlet hose 11 connecting the outlet pipe and the water collecting tank is fixed in the water collecting tank 5 by the round pipe fixing buckle 6 to prevent sewage from splashing. The sewage entering the water collecting tank passes through the garbage screen 4, filters out solid garbage, and enters the left side of the water collecting tank 5 for secondary use.

[0040] Figure 2 In the embodiment, the positioning spring 19 increases the rigidity and stability through the positioning rail 15 (the positioning rail can be a metal rod with a certain hardness), so that it can support the positioning block 18 to be placed in the pipeline. The positioning adjustment groove 16 is reserved to adapt to pipelines of different diameters.

[0041] Figure 3 The spiral conduit 14 can be adjusted to be close to the pipe wall, bend to different curvatures, and maintain a certain strength to adapt to different pipe diameters and enable the spiral outlet nozzle 10 to form different inclination angles.
