Description

Technical Field

[0001] This utility model relates to the field of specialized process design, specifically to a snow melting agent preparation system. Background Technology

[0002] In northern cities, when it snows in winter, it is necessary to carry out snow melting and ice removal operations on urban roads. There are usually two methods for snow melting and ice removal operations: one is to directly spread snow melting agent granules, and the other is to spray snow melting agent solution.

[0003] The principle of snow and ice melting is that when salt dissolves in water, ions interact with water molecules, breaking the hydrogen bonds between them. These ions occupy the space between water molecules, making it difficult for them to form ice crystals. Therefore, the freezing point of the salt water is lowered, thus melting the snow and ice. Compared to spreading solid snow-melting agent particles, spraying liquid snow-melting agent solutions has the advantages of higher snow-melting efficiency and a wider range of action. However, the preparation of liquid snow-melting agent solutions requires dedicated snow-melting agent mixing stations, which generally only operate during winter, resulting in low utilization and relatively low preparation efficiency. Therefore, the overall adoption rate is low, with such stations only found in a few large cities. Conventional snow-melting agent mixing stations typically include mixing tanks and storage tanks. The basic process of conventional snow-melting agent mixing stations in existing technology is as follows: Figure 1 As shown.

[0004] Therefore, there is an urgent need to develop more efficient, environmentally friendly, and economical de-icing agent preparation systems to improve the overall performance and efficiency of de-icing agent mixing plants. Utility Model Content

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Reference will now be made in detail to various embodiments of the present invention, examples of which are shown in the accompanying drawings and described below. For ease of interpretation and precise definition in the appended claims, the terms “upper,” “lower,” “inner,” and “outer” are used to describe features with reference to their location in the exemplary embodiments shown in the figures.

[0034] Figure 2 , Figure 3 The figures show a basic process diagram of the de-icing agent mixing station and a top view of the de-icing agent preparation system according to an embodiment of the present invention. As shown in the figures, an embodiment of the present invention provides a de-icing agent preparation system, including: a feeding device for transporting de-icing agent material ton bags; a bag breaker for breaking open the de-icing agent material ton bags and releasing de-icing agent particles; a mixing tank for dissolving the de-icing agent particles to obtain a de-icing agent solution; and a storage tank for storing the de-icing agent solution.

[0035] Embodiments of the present utility model adopt an integrated snow-melting agent solution preparation device, which can improve the overall performance and efficiency of the snow-melting agent mixing station.

[0036] Figure 4 The schematic diagram of the bag breaker according to an embodiment of the present utility model is shown. As shown in the figure, according to an embodiment of the present utility model, the bag breaker includes: an electric hoist located above the bag breaker for lifting and transporting the ton bag of snow-melting agent material into the bag breaker; and a cutter located inside the bag breaker for breaking the ton bag of snow-melting agent material.

[0037] Figure 5 The sectional view of the mixing tank according to an embodiment of the present utility model is shown. As shown in the figure, according to an embodiment of the present utility model, the mixing tank includes: a water supply pipe extending from the upper part to the bottom of the mixing tank for supplying water to the mixing tank; a rapid mixing chamber connected to the water supply pipe, and a high-speed stirrer is equipped in the rapid mixing chamber for quickly mixing the snow-melting agent particles and water to obtain a snow-melting agent mixture; a ripening chamber, and one or more slow stirrers are arranged in the ripening chamber for slowly stirring the snow-melting agent mixture from the rapid mixing chamber to obtain the snow-melting agent solution; and a pumping chamber for pumping the snow-melting agent solution from the ripening chamber to the storage tank.

[0038] In the embodiments of the present utility model, the stirrer supporting the rapid mixing chamber has a relatively high rotation speed, and the water supply of the mixing tank is also connected to the rapid mixing chamber. After the rapid mixing chamber is the ripening chamber, and multiple slow stirrers are arranged in the ripening chamber. The purpose of the ripening chamber is to further accelerate the dissolution of the snow-melting agent particles and the tap water medium.

[0039] Among them, the difference between the rapid mixing chamber and the ripening chamber is that: the rapid mixing chamber is equipped with a high-speed stirrer for quickly mixing the snow-melting agent particles and water to quickly form a mixture. High-speed stirring helps to quickly disperse the snow-melting agent and reduce the risk of caking and uneven mixing. It can quickly disperse the snow-melting agent particles and reduce the risk of local supersaturation and precipitation, but it may not be sufficient to achieve complete dissolution. While the ripening chamber is equipped with slow stirrers, the purpose is to allow the snow-melting agent particles to have more time to react with water under slower stirring to achieve more complete dissolution and ripening, and improve the stability and uniformity of the solution. It is used to slowly stir the snow-melting agent mixture for a long time to promote a more thorough dissolution and ripening process.

[0040] According to an embodiment of the present invention, the mixing tank further includes: an intermediate baffle connected to the bottom of the mixing tank and disposed between the rapid mixing chamber and the curing chamber, the intermediate baffle having an opening at the bottom for allowing the de-icing agent mixture to flow from the rapid mixing chamber into the curing chamber; and an overflow baffle connected to the bottom of the mixing tank and disposed between the curing chamber and the pumping chamber for allowing the de-icing agent solution to flow from the curing chamber into the pumping chamber, and switching the preparation mode via a bypass pipe: wherein, when a high concentration of de-icing agent solution is required, the valve of the bypass pipe is closed; after the high concentration of de-icing agent solution is prepared, the valve of the bypass pipe is opened, allowing the de-icing agent solution in the curing chamber to enter the pumping chamber through the bypass pipe; and when a low concentration of de-icing agent solution is required, the valve of the bypass pipe is closed, allowing the de-icing agent solution in the curing chamber to enter the pumping chamber through the overflow baffle.

[0041] In this embodiment of the invention, an intermediate baffle is provided between the curing chamber and the rapid mixing chamber. The intermediate baffle is used to divide the mixing tank. On the one hand, it can make the de-icing agent particles and tap water quickly mix and stir. On the other hand, when the liquid level in the rapid mixing chamber reaches a certain height, the solution can cross the baffle and enter the curing chamber. A water passage hole is provided at the bottom of the intermediate baffle to enable the rapid mixing chamber and the curing chamber to be connected.

[0042] After passing through the maturation chamber, the liquid enters the pumping chamber, with an overflow baffle installed between the two. A bypass pipe is also connected between the maturation chamber and the pumping chamber. This design ensures that the preparation module can employ two different preparation modes: continuous preparation and intermittent preparation.

[0043] In continuous preparation mode, the bypass pipe is closed, and the liquid solution enters the pumping chamber through the overflow plate. This mode is for low-concentration liquids. Intermittent preparation mode is for solutions requiring ultra-high concentrations. In this mode, the inlet water level in the rapid stirring chamber must be kept below the overflow plate to ensure the solution is fully dissolved in the maturation chamber. When the ultra-high concentration is reached, the valve on the connecting pipe is opened to allow the liquid in the maturation chamber to enter the pumping chamber.

[0044] According to an embodiment of this utility model, the bypass pipe is controlled by the following formula:

[0045]

[0046] Among them, V 旁通 C is the valve opening of the bypass pipeline (unit: %, 0% indicates closed, 100% indicates fully open), and C is the required concentration of the de-icing agent solution (unit: %). 高 It is a high concentration threshold;

[0047] The overflow baffle is controlled by the following formula:

[0048]

[0049] Among them, V 溢流 This is the valve opening degree of the overflow baffle (unit: %, 0% indicates closed, 100% indicates fully open);

[0050] The flow rate of the snow-melting agent solution is calculated according to the following formula:

[0051]

[0052] Among them, Q 熟化 The flow rate (in L / min) of the de-icing agent solution flowing out of the curing chamber, Q 泵送 This is the flow rate of the de-icing agent solution entering the pumping chamber (unit: L / min).

[0053] This embodiment of the invention achieves automatic adjustment of the concentration of the de-icing agent solution by precisely controlling the valve opening of the bypass pipe and the overflow steel plate, thereby improving the efficiency and accuracy of the preparation process.

[0054] According to an embodiment of the present invention, the maturation chamber includes: a maturation chamber baffle connected to the top of the maturation chamber for separating multiple slow-speed stirrers; and an overflow weir located at the upper part of the maturation chamber, wherein a weir groove filter screen is provided at the upper part of the overflow weir for filtering impurities.

[0055] In this embodiment of the invention, a baffle plate is provided inside the curing chamber to separate the slow-speed agitators and prevent them from interfering with each other. A weir filter screen is provided above the overflow weir of the curing chamber to filter impurities.

[0056] Figure 6 A cross-sectional view of a storage tank and conveying device according to an embodiment of the present invention is shown. As shown in the figure, according to the embodiment of the present invention, the storage tank is connected to other storage tanks through an overflow pipe, a vent pipe and a connecting pipe to form a series structure of multiple storage tanks to increase the storage capacity; the bottom of the high-speed agitator is set in an inverted cone shape to prevent the snow melting agent particles from accumulating at the bottom and to prevent the formation of a stirring dead zone.

[0057] In this embodiment of the utility model, the liquid storage tank is equipped with an overflow pipe, a vent pipe, and a connecting pipe. The function of the connecting pipe is to connect the storage modules in series, thereby increasing the liquid storage capacity.

[0058] According to an embodiment of the present invention, the de-icing agent preparation system further includes a conveying device, which includes: a valve group for adjusting the flow direction of the de-icing agent solution to ensure uniform delivery; a water pump connected to the storage tank for conveying the de-icing agent solution to a water truck; the de-icing agent preparation system further includes a return circulation pipe, one end of which is connected to the storage tank and the other end is connected back to the pumping chamber to ensure that the de-icing agent solution in the storage tank achieves self-circulation.

[0059] In this embodiment of the utility model, the delivery system of the storage module consists of a water pump and its valve group, and a return circulation pipe is also provided to ensure that the liquid in the storage tank can achieve self-circulation, prevent undissolved de-icing agent particles from depositing in the storage tank, and at the same time, the setting of the return pipe can prevent the water pump from repeatedly starting and stopping under continuous filling.

[0060] According to another embodiment of the present invention, a method for preparing a de-icing agent is provided, comprising the following steps: using a feeding device to transport a de-icing agent material ton bag; using a bag breaker to break open the de-icing agent material ton bag and release de-icing agent particles; dissolving the released de-icing agent particles in a mixing tank to obtain a de-icing agent solution; and storing the de-icing agent solution in a storage tank.

[0061] According to an embodiment of this utility model, dissolving the released de-icing agent particles in a mixing tank to obtain a de-icing agent solution includes: supplying water to the bottom of the mixing tank through a water supply pipe; using a high-speed stirrer in a rapid mixing chamber connected to the water supply pipe to rapidly mix the de-icing agent particles and water to obtain a de-icing agent mixture; transferring the de-icing agent mixture from the rapid mixing chamber to a maturation chamber, and using one or more slow stirrers provided in the maturation chamber to slowly stir and further dissolve the de-icing agent particles to obtain the de-icing agent solution; and pumping the de-icing agent solution in the maturation chamber to the storage tank through a pumping chamber.

[0062] The process flow of this device is as follows: Ton bags of de-icing agent granules are transported to the feeding module using a combination of manual labor and forklifts. The bag-breaking device in the feeding module lifts the ton bags and sends them into the bag-breaking device for breaking. After breaking, the de-icing agent falls through the conical hopper at the bottom of the bag-breaking device into the mixing tank. The mixing tank is equipped with a water supply pipe and a mixer. After the de-icing agent granules dissolve in the mixing tank, they are pumped or overflowed into the storage module. The finished de-icing agent solution in the storage tank is then pumped into water trucks.

[0063] The bag-breaking device of this utility model is placed on a steel frame. The bag-breaking device and the auger are manufactured in the factory and transported to the site. Then, the two are assembled on the steel frame on the site, and the steel frame is fixed to a concrete foundation.

[0064] The bag breaker is equipped with an electric hoist and internal blades.

[0065] This invention features a multi-stage preparation chamber, comprising a rapid mixing chamber, a curing chamber, and a pumping chamber. The rapid mixing chamber is equipped with a high-speed agitator, and water from the mixing tank is also supplied to it. Following the rapid mixing chamber is the curing chamber, separated from the rapid mixing chamber by a steel grating. This grating serves to divide the mixing tank, allowing for rapid mixing and blending of the de-icing agent particles with tap water. Furthermore, when the liquid level in the rapid mixing chamber reaches a certain height, the solution can overflow the grating and enter the curing chamber. The bottom of the steel grating has drainage holes to connect the rapid mixing chamber and the curing chamber. The curing chamber is equipped with multiple slow-speed agitators to further accelerate the dissolution of the de-icing agent particles with the tap water. An internal baffle separates the slow-speed agitators, preventing mutual interference. After passing through the curing chamber, the liquid enters the pumping chamber, separated from the curing chamber by an overflow steel plate. A bypass pipe is also installed between the curing chamber and the pumping chamber. This is to ensure the preparation module can operate in two different modes: continuous preparation and intermittent preparation. In continuous preparation mode, the connecting pipe is closed, and the liquid solution enters the pumping chamber through the overflow plate. This mode is for low-concentration liquids. Intermittent preparation mode is used when ultra-high concentration solutions are required. In this mode, the inlet water level in the rapid stirring chamber must be kept below the overflow plate to ensure the solution is fully dissolved in the curing chamber. When the ultra-high concentration is reached, the valve on the connecting pipe is opened, allowing the liquid in the curing chamber to enter the pumping chamber.

[0066] The steel grating inside the rapid mixing chamber has openings at the bottom to ensure that the rapid mixing chamber and the curing chamber are connected.

[0067] The overflow weir of the maturation chamber is equipped with a weir trough filter screen, the purpose of which is to filter impurities.

[0068] The delivery system of the preparation module consists of a valve group and a water pump, and its main function is to deliver the solution in the pumping chamber to the storage tank for storage.

[0069] The liquid storage tank is equipped with an overflow pipe, a vent pipe, and a connecting pipe. The connecting pipe allows the storage modules to be connected in series, thereby increasing the liquid storage capacity.

[0070] The tank of the preparation module is designed with an inverted cone shape to prevent the de-icing agent material from accumulating at the bottom of the agitator and to prevent the existence of a dead zone in the agitator.

[0071] The storage module's delivery system consists of a water pump and its valve assembly, and also includes a return circulation pipe to ensure that the liquid in the storage tank can circulate on its own, preventing undissolved de-icing agent particles from settling in the storage tank. At the same time, the return pipe prevents the water pump from repeatedly starting and stopping during continuous filling.

[0072] This utility model has the following advantages:

[0073] (1) Integrating the traditional de-icing agent solution preparation process: This utility model integrates the traditional de-icing agent solution preparation process, that is, integrating multiple production steps such as raw material preparation, solution preparation, and injection into a unified and integrated system, which can not only improve production efficiency, reduce energy consumption and raw material waste, but also improve the consistency and reliability of product quality.

[0074] (2) Enhance the applicability of the snow melting agent solution preparation device: By setting two different preparation modes, low-concentration liquid can be obtained through continuous preparation mode and high-concentration liquid can be obtained through intermittent preparation mode according to actual needs. This makes it more flexible, significantly improves the adaptability and efficiency under different application requirements, and better meets the needs of different application scenarios.

[0075] (3) Improve the efficiency of snow melting agent solution preparation: The rapid mixing chamber, steel grating and curing chamber promote the rapid mixing and further accelerated dissolution of snow melting agent particles with tap water. At the same time, the tank of the preparation module is equipped with an inverted cone to prevent the existence of a stirring dead zone, so as to achieve full mixing and effectively improve the preparation efficiency of snow melting agent solution.

[0076] (4) Improve the overall performance of the de-icing agent preparation system: By integrating a reflux circulation pipe into the de-icing agent preparation system, a highly efficient circulation system is constructed, thereby maintaining the uniform mixing and suspension of the de-icing agent solution, effectively preventing undissolved de-icing agent particles from depositing at the bottom of the pool, avoiding equipment maintenance problems and solution performance degradation caused by deposition, and improving the overall performance of the entire system.
