Description

Technical Field

[0001] This utility model relates to an intelligent water replenishment device for a high-pressure washer. Background Technology

[0002] During polyester production, as the material flows from the prepolymerization reactor 15R01 to the final polymerization reactor 17R01 via the booster pump 16P01, inescapable and non-molten aggregated particles are inevitably generated. The presence of these particles increases the pressure in the spinning metering pump assembly, shortening its lifespan. Therefore, a prepolymerization duplex filter 16F01 is added to the melt conveying system to intercept these aggregated particles and achieve a filtering effect. Simultaneously, the filter element inside the duplex filter needs to be cleaned regularly to remove accumulated aggregated particles. The filter element cleaning requires alkaline washing in a hydrolysis furnace, high-pressure rinsing, and ultrasonic cleaning.

[0003] In routine high-pressure rinsing operations, the demineralized water was originally directly connected to the high-pressure rinsing machine from the demineralized water main pipe. As a result, the spray volume of the high-pressure impact machine's spray head is easily affected by the pressure fluctuations in the main pipe. When the pressure is unstable, the O-ring seal of the high-pressure rinsing machine's water pump will wear and break, eventually causing the spray head to become clogged, affecting the spray volume and resulting in poor rinsing effect. This leads to incomplete rinsing of impurities in the filter element, which will greatly shorten the service life of the filter element. Consequently, the pressure of the spinning assembly will rise too quickly, affecting the melt viscosity adjustment and the quality of the spun products. Utility Model Content

[0004] The main objective of this invention is to provide an intelligent water replenishment device for a high-pressure washer, which solves the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent water replenishment device for a high-pressure washer, comprising a control cabinet and a high-pressure washer, wherein a cleaning water tank is provided on one side of the high-pressure washer, and a demineralized water main pipe is provided on one side of the cleaning water tank; a first pipeline is provided between the high-pressure washer and the cleaning water tank, and a second pipeline is provided between the demineralized water main pipe and the cleaning water tank.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: a water pump is provided on the first pipeline.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a solenoid valve is provided on the second pipeline.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the cleaning water tank is equipped with a float-type liquid level controller and a high-level alarm, both of which are electrically connected to the control cabinet.

[0009] Based on the above scheme and as a preferred embodiment, the volume of the cleaning water tank is 0.77 m³. 3 .

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The cleaning water tank setting can better ensure the stability of water pressure of the high-pressure washer spray head, and avoid the O-ring seal of the high-pressure washer water pump from breaking due to excessive water pressure fluctuation, which would affect the spray flow and ultimately lead to poor washing effect;

[0012] 2. It eliminates the unnecessary step of manual water replenishment, saving manpower. At the same time, the intelligent replenishment of the cleaning water tank level is more stable than manual replenishment, and avoids the situation where the cleaning water tank level is too low or the demineralized water in the cleaning water tank dries up due to human negligence, which may cause damage to the water pump.

[0013] 3. The central control unit can monitor the changes in the water level in the cleaning tank and the operation of the high-pressure flushing machine in real time, realizing remote monitoring. Any abnormalities can be reported to on-site personnel for timely intervention.

[0014] 4. The entire system achieves intelligent operation, which is more convenient and precise than manual operation. The stable operation of the high-pressure washer ensures that the filter element cleaning effect is in the best state. The cleaner filter element enables the melt conveying system of polyester production to better filter impurities, making the polyester reaction more stable, the melt viscosity tends to be stable, the pressure of the spinning component tends to be stable, and extending its service life.

However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0017] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] See attached diagram. Figure 1 An intelligent water replenishment device for a high-pressure washer in this embodiment includes a control cabinet 6 and a high-pressure washer 2. A cleaning water tank 3 is provided on one side of the high-pressure washer 2, and a demineralized water main pipe 1 is provided on one side of the cleaning water tank 3. A first pipeline is provided between the high-pressure washer 2 and the cleaning water tank 3, and a second pipeline is provided between the demineralized water main pipe 1 and the cleaning water tank 3.

[0022] Furthermore, a water pump 5 is installed on the first pipeline.

[0023] Furthermore, a solenoid valve 4 is installed on the second pipeline.

[0024] Furthermore, the cleaning water tank 3 is equipped with a float-type level controller and a high-level alarm, both of which are electrically connected to the control cabinet. The high-level alarm in the cleaning water tank 3 indicates that the water level has reached 80% of the total level, and the signal will be connected to the central control DCS system for real-time monitoring and control of the water level.

[0025] A solenoid valve 4 is installed between the cleaning water tank 3 and the demineralized water main pipe 1 to control water replenishment. The central control DCS system monitors the liquid level and controls water replenishment in real time. During the rinsing process, when the high level alarm in the cleaning water tank 3 disappears for 20 seconds, the solenoid valve 4 opens and automatically starts replenishing water until the cleaning water tank level alarm rises again, at which point the solenoid valve 4 closes and stops replenishing water. This saves time and labor costs associated with manual water replenishment, ensures that regular on-site operations can be carried out normally, and to a certain extent, contributes to the stability of polyester production.

[0026] Furthermore, the volume of the cleaning water tank 3 is 0.77m³. 3 The high-pressure washer 2 performs 6 external rinsings and 1 internal rinsing per cycle, requiring 10,800L of demineralized water. The cleaning water tank 3 has a capacity of 770L. Using the original manual water replenishment method, the water level in cleaning water tank 3 needs to be continuously replenished to ensure sufficient water for the rinsing operation. This necessitates on-site process personnel to perform irregular water replenishment, increasing on-site labor costs. Furthermore, the daily on-site process operations are carried out slowly, and the inability to perform these regular operations could lead to potential instability in polyester production.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
