Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically, a detachable, green and environmentally friendly pipeline fluid ice slurry cleaning device. Background Technology

[0002] The principle behind pipe cleaning technology is to utilize the shear force of ice (2 to 4 orders of magnitude greater than that of water). After ice slurry is injected into the pipe, it is propelled by the pressure of the municipal water supply. During its movement, the ice slurry collides and rubs against the inner wall of the pipe, disrupting the stable structure of deposits and attachments, causing them to peel off. These detached materials flow forward with the ice slurry and are eventually discharged from the pipe, thus achieving the effect of pipe cleaning.

[0003] Existing pipeline ice slurry cleaning equipment has the following problems: 1. The ice-water mixture used for cleaning is usually pumped by an ice-discharging screw pump, but long-term operation will cause ice to form on the inner wall of the pump, resulting in increased pump operating resistance and power consumption; moreover, the wear of the spiral blades will increase sharply, leading to high subsequent maintenance frequency and high maintenance costs; 2. The integrated ice-making and ice-storage cleaning equipment is usually 8-10 meters or more in length, making it difficult to pass through residential areas and narrow roads; 3. Vehicle-mounted pipeline ice slurry cleaning equipment requires high initial equipment investment, with vehicle investment costs estimated at 450,000 to 600,000 yuan, which is difficult for many companies to afford; 4. When transporting ice storage equipment for operation, the lack of a power supply system will lead to a lack of working conditions on site. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] This embodiment provides a detachable, green, and environmentally friendly pipeline fluidized ice slurry cleaning device, specifically as follows: Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, it includes:

[0031] An integrated ice-making system includes an ice-making container 101, which houses an ice-making unit for making ice.

[0032] An integrated ice storage system includes an ice storage container 210, which houses an ice storage unit for storing ice and an ice removal unit for removing ice.

[0033] The ice removal unit includes an ice-discharging screw pump, which includes an ice-discharging motor 301, a bracket 302, an outer cylinder 303, and a main shaft 305. The ice-discharging motor 301 and the outer cylinder 303 are both mounted on the bracket 302. The feed end of the outer cylinder 303 is connected to the discharge end of the ice removal unit. The main shaft 305 is drivenly connected to the ice-discharging motor 301. A spiral blade 306 is provided on the main shaft 305, and multiple de-icing blades 307 are mounted on the spiral blade 306.

[0034] When cleaning the pipes to be cleaned, an integrated ice-making system is used to make ice blocks, which are then transported through pipes to an integrated ice storage system. In the ice storage unit, water and ice blocks are mixed, and then the ice-water mixture is transported to the ice discharge unit. The ice-water mixture is pressurized in the ice discharge screw pump and then discharged into the pipes to be cleaned. The impact force of the ice blocks is used to clean the dirt in the pipes to be cleaned until the water discharged from the end of the pipes to be cleaned is clear.

[0035] Specifically, when the ice-water mixture flows in from the feed end of the outer cylinder 303, the ice-discharging motor 301 drives the main shaft 305 to rotate, causing the ice-water mixture propelled by the spiral blade 306 to flow towards the discharge end of the outer cylinder 303. During this process, the ice-water mixture is pressurized, allowing it to be flushed into the pipe to be cleaned. After prolonged use, the inner wall of the outer cylinder 303 of a conventional screw pump may freeze, thus increasing the resistance to the rotation of the spiral blade 306 and increasing power consumption. Simultaneously, automatically cleaning the ice from the outer cylinder 303 wall by the rotation of the spiral blade 306 will exacerbate wear on the spiral blade 306. Therefore, this device adds a de-icing blade 307, which rotates along with the spiral blade 306. The de-icing blade 307 first removes the ice adhering to the inner wall of the outer cylinder 303, making de-icing easier than with the spiral blade 306 and reducing wear on the spiral blade 306. After prolonged use, only the de-icing blade 307 needs to be replaced. By setting up the de-icing blade 307, the ice on the inner wall of the outer cylinder 303 can be removed more easily, and the wear of the spiral blade 306 can be effectively reduced.

[0036] By separating the integrated ice-making system from the integrated ice storage system, the weight and volume of vehicles used for field operations can be reduced, making operations more flexible, especially when operating in alleyways. The use of ice-making containers 101 and ice storage containers 210 to support the ice-making unit, ice storage unit, and ice removal unit, i.e., the non-vehicle-mounted structure, significantly reduces the initial investment in equipment, which can alleviate the initial economic pressure on some enterprises.

[0037] Example 2:

[0038] This embodiment further expands upon the ice-discharging screw pump based on the above embodiments, specifically as follows: Figure 4 , Figure 6 As shown, the shadows of the multiple de-icing blades 307 projected along the axial direction of the main shaft 305 do not overlap and form a continuous line segment. This arrangement allows the multiple de-icing blades 307 to not only fully cover the inner wall of the outer cylinder 303 and remove ice, but also to minimize the overall cross-section of the multiple de-icing blades 307, thereby reducing the rotational resistance of the spiral blades 306.

[0039] Furthermore, the pitch of the spiral blade 306 is gradually changing, with the pitch of the spiral blade 306 near the feed end of the outer cylinder 303 being greater than the pitch near the discharge end of the outer cylinder 303. During the movement of the ice-water mixture, the compression becomes increasingly intense, allowing the ice-water mixture to possess greater kinetic energy when discharged from the outer cylinder 303, thus increasing its conveying distance.

[0040] Furthermore, the ice removal unit also includes an ice removal pipe 308. A connecting flange pipe 304 is installed on the outer cylinder 303, and the ice removal pipe 308 is connected to the connecting flange pipe 304. The ice removal pipe 308 is connected to the pipe to be cleaned. The ice removal pipe 308 has the same diameter as the pipe to be cleaned. The connecting flange pipe 304 is used to ensure that the ice removal pipe 308 can be connected to the outer cylinder 303. That is, the operator can select a suitable connecting flange pipe 304 according to the size of the pipe to be cleaned to connect the ice removal pipe 308 to the outer cylinder 303. This adapts to cleaning operations of pipes with different diameters.

[0041] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0042] Example 3:

[0043] This embodiment further expands upon the above embodiments by extending the ice-making unit and the ice-storage unit, specifically as follows: Figures 1-4 As shown, the ice-making unit includes a condenser 102, a compressor 103, an ice maker 104, an ice-making water inlet pipe 105, an ice-making discharge pipe 106, an oil separator 107, a first winding frame 108, a liquid receiver 109, and a return gas heat exchanger 110. The ice-making water inlet pipe 105 is connected to the feed end of the ice maker 104, and the ice-making discharge pipe 106 is connected to the discharge end of the ice maker 104. The condenser 102 is used to dissipate heat from the refrigerant in the compressor 103, and the refrigerant in the compressor 103 is used to cool the ice maker 104. The liquid receiver 109 is used to store refrigerant. The oil separator 107 is used to separate the lubricating oil from the returned refrigerant. The return gas heat exchanger 110 is used to further heat the returned refrigerant.

[0044] Furthermore, the ice storage unit includes an ice inlet pipe 201, a drain pipe 202, a water supply pipe 203, an internal circulation water pump 204, an oil tank 205, a second winding frame 206, a diesel generator 207, and a stirring ice storage tank 208. The ice inlet pipe 201 is connected to the water inlet of the stirring ice storage tank 208, the drain pipe 202 is connected to the water outlet of the stirring ice storage tank 208, the water supply pipe 203 is connected to the water supply outlet of the stirring ice storage tank 208, and the ice outlet of the stirring ice storage tank 208 is connected to the outer cylinder 303. The oil tank 205 supplies oil to the diesel generator 207, which in turn supplies power to the integrated ice-making system and the integrated ice storage system. An internal circulation pipe assembly is also installed on the stirring ice storage tank 208, and an internal circulation water pump 204 is installed on the internal circulation pipe assembly. The pipe connections in this device use quick-connect flexible hoses, making it flexible and convenient to use.

[0045] The pipeline ice slurry cleaning process consists of five core steps: refrigeration cycle, ice crystal formation, ice slurry mixing and storage, ice slurry transportation, and pipeline cleaning. The refrigeration cycle and ice crystal formation are completed within the integrated ice-making system, while the ice slurry mixing and storage, and ice slurry transportation are completed within the integrated ice storage system. Specifically:

[0046] The refrigeration cycle includes:

[0047] S11, the compressor 103 drives the refrigerant circulation; the compressor 103 compresses the low-temperature, low-pressure gaseous refrigerant (such as R404A) into a high-temperature, high-pressure gas, which is then delivered to the condenser 102 through the exhaust pipe;

[0048] S12, condensation and heat dissipation; the condenser 102 uses forced air convection to condense the high-temperature refrigerant gas into a high-pressure liquid state, which then flows into the liquid receiver 109 for temporary storage.

[0049] S13, Throttling and Evaporative Refrigeration: Liquid refrigerant enters the expansion valve through the liquid supply pipe for throttling and pressure reduction, becoming a low-temperature, low-pressure gas-liquid mixture, and then enters the ice maker 104;

[0050] Ice crystal formation includes:

[0051] S21. The ice maker 104 acts as an evaporator, with its surface temperature dropping below -10℃. When the ice-making water pump delivers water through the ice-making water inlet pipe 105 to the inner wall of the ice maker 104, the water flows in a supercooled state (below 0℃ but not frozen). When disturbed, it instantly nucleates and crystallizes, forming micron-sized ice crystals (about 0.1-1mm in diameter). The ice crystals are scraped off into the ice dropper by the rotation of its inner ice blade, and then delivered to the integrated ice storage system by the ice-making ice discharge pump through the ice discharge pipe 106.

[0052] Ice slurry mixing and storage include:

[0053] S31, Anti-condensation stirring: Ice in the ice discharge pipe 106 enters the stirring ice storage tank 208 through the ice inlet pipe 201, and tap water is added through the water supply pipe 203, so that the ice and water in the stirring ice storage tank 208 mix to form ice slurry (the ice-water mixing ratio can reach 30%-50%); the stirring ice storage tank 208 rotates continuously at a low speed (10-30 rpm), using the shearing force of the blades to prevent ice crystals from agglomerating into blocks and maintain the uniform flow of ice slurry;

[0054] S32, Dynamic internal circulation; The internal circulation water pump 204 drives the stirring ice storage tank 208 to replenish the liquid in the ice maker 104, continuously increasing the ice slurry concentration;

[0055] S33. Temperature control; the exhaust fan regulates the ambient temperature inside the box to prevent the ice slurry from melting due to external heat input or from solidifying due to excessive cooling.

[0056] Ice slurry delivery includes:

[0057] S41, High viscosity pumping; The ice discharge screw pump uses low speed and high torque characteristics (speed <100rpm) to draw ice slurry and deliver it to the cleaning pipeline through the ice discharge pipe 308;

[0058] S42, Closed-loop control; The electronic control system monitors the ice slurry temperature (-2-0℃), density (800-900kg / m³), and flow rate in real time, and dynamically adjusts the ice-making rate and stirring intensity to ensure stable ice slurry output;

[0059] Pipe cleaning includes:

[0060] S51. Due to the shear-thinning effect (non-Newtonian fluid characteristics), the ice slurry in the pipeline has increased fluidity. Upon reaching a narrow pipe, it expands rapidly due to pressure release, using phase change impact force to peel off dirt. The ice slurry is delivered to about 30%-50% of the volume of the pipe to be cleaned, and the ice screw pump stops discharging. The valve on the pipe to be cleaned is opened, and the tap water pressure is used to push the ice slurry forward, peeling off the dirt inside the pipe. Finally, it is discharged at the end. After all the ice slurry has been discharged from the pipe and the water is clear again, the valve is closed, and the pipeline cleaning work is completed.

[0061] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
