Description

Technical Field

[0001] The invention relates to the field of special process design, and in particular to a snow-melting agent preparation system and method. Background Art

[0002] In northern cities, when it snows in winter, it is necessary to melt snow and ice on urban roads. There are usually two ways to melt snow and ice: one is to directly spread snow-melting agent particles, and the other is to spray snow-melting agent solution.

[0003] The principle of snow melting and ice thawing is that when salt is dissolved in water, ions will interact with water molecules, breaking the hydrogen bonds between water molecules. These ions will occupy the space between water molecules, making it difficult for water molecules to form ice crystals. Therefore, the freezing point of salt water will be lowered, causing the snow and ice to melt. Therefore, compared with broadcasting solid snow melting agent particles, spraying liquid snow melting agent solution has the characteristics of high snow melting efficiency and wide range of action. However, since the preparation of liquid snow melting agent solution requires a dedicated snow melting agent mixing station, this type of station is generally only operated in winter, so the utilization rate is not high. In addition, the preparation efficiency is low, so the overall penetration rate is not high, and it is only set up in some large cities. Conventional snow melting agent mixing stations are generally equipped with a mixing tank and a liquid storage tank. The basic process of conventional snow melting agent mixing stations in the prior art is as follows: Figure 1 shown.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] 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 of the exemplary embodiments shown in the drawings with reference to their positions.

[0026] Figure 2 , Figure 3 The basic process diagram of a de-icing agent mixing station according to an embodiment of the present invention and a top view of a de-icing agent preparation system are respectively shown. As shown in the figure, an embodiment of the present invention provides a de-icing agent preparation system, including: a loading device for transporting ton bags of de-icing agent materials; a bag breaker for breaking open the ton bags of de-icing agent materials and releasing de-icing agent particles; a stirring tank for dissolving the de-icing agent particles to obtain a de-icing agent solution; and a liquid storage tank for storing the de-icing agent solution.

[0027] The embodiment of the present invention can improve the overall performance and benefits of a de-icing agent mixing station through an integrated de-icing agent solution preparation device.

[0028] Figure 4A schematic diagram of a bag breaker according to an embodiment of the present invention is shown. As shown in the figure, according to the embodiment of the present invention, the bag breaker includes: an electric hoist, located above the bag breaker, for lifting and conveying the ton bag of snow-melting agent material into the bag breaker; a cutter, located inside the bag breaker, for breaking open the ton bag of snow-melting agent material.

[0029] Figure 5 A cross-sectional view of a stirring tank according to an embodiment of the present invention is shown. As shown in the figure, according to the embodiment of the present invention, the stirring tank includes: a water supply pipe extending from the upper part to the bottom of the stirring tank, for supplying water to the stirring tank; a rapid stirring bin connected to the water supply pipe, the rapid stirring bin is equipped with a high-speed stirrer, for rapidly mixing the deicing agent particles and water to obtain a deicing agent mixture; a maturation bin, the maturation bin is equipped with one or more slow stirrers, for slowly stirring the deicing agent mixture from the rapid stirring bin to obtain the deicing agent solution; a pumping bin, for pumping the deicing agent solution from the maturation bin to the liquid storage tank.

[0030] In the embodiment of the present invention, the stirrer matched with the rapid stirring chamber has a high speed, and the water supply of the stirring tank is also connected to the rapid stirring chamber. After the rapid stirring chamber is the maturation chamber, which is equipped with multiple slow stirrers. The purpose of the maturation chamber is to further accelerate the dissolution of the snow melting agent particles and the tap water medium.

[0031] The difference between the fast mixing chamber and the maturation chamber is that the fast mixing chamber is equipped with a high-speed agitator to quickly mix the deicing agent particles and water to quickly form a mixture. High-speed stirring helps to quickly disperse the deicing agent and reduce the risk of agglomeration and uneven mixing. It can quickly disperse the deicing agent particles and reduce the risk of local oversaturation and precipitation, but it may not be enough to achieve complete dissolution. The maturation chamber is equipped with a slow agitator, the purpose of which is to allow the deicing agent particles to have more time to react with water under slower stirring to achieve more complete dissolution and maturation, and improve the stability and uniformity of the solution. It is used to slowly stir the deicing agent mixture over a longer period of time to promote a more thorough dissolution and maturation process.

[0032] According to an embodiment of the present invention, the mixing tank further includes: an intermediate baffle, connected to the bottom of the mixing tank, disposed between the rapid mixing bin and the maturation bin, the bottom of the intermediate baffle having a hole for allowing the deicing agent mixture to flow from the rapid mixing bin into the maturation bin; an overflow baffle, connected to the bottom of the mixing tank, disposed between the maturation bin and the pumping bin, for allowing the deicing agent solution to flow from the maturation bin into the pumping bin, and switching the preparation mode through a bypass pipe: wherein, when a high-concentration deicing agent solution is required, the valve of the bypass pipe is closed, and when the high-concentration deicing agent solution is prepared, the valve of the bypass pipe is opened to allow the deicing agent solution in the maturation bin to enter the pumping bin through the bypass pipe; when a low-concentration deicing agent solution is required, the valve of the bypass pipe is closed to allow the deicing agent solution in the maturation bin to enter the pumping bin through the overflow baffle.

[0033] In the embodiment of the present invention, an intermediate baffle is provided between the maturation bin and the rapid stirring bin. The function of the intermediate baffle is to divide the stirring tank. On the one hand, the snow melting agent particles and the tap water can be quickly blended and stirred. On the other hand, when the liquid level in the rapid stirring bin reaches a certain height, the solution can cross the partition and enter the maturation bin. A water hole is provided at the bottom of the intermediate baffle for realizing relative communication between the rapid stirring bin and the maturation bin.

[0034] After the liquid passes through the maturation chamber, it enters the pumping chamber. An overflow baffle is set between the pumping chamber and the maturation chamber. At the same time, a bypass pipeline is also set between the maturation chamber and the pumping chamber. The purpose of this is to ensure that the preparation module can adopt two different preparation modes: continuous preparation mode and intermittent preparation mode.

[0035] When the continuous preparation mode is adopted, the bypass pipeline is closed, and the liquid solution enters the pumping chamber through the overflow plate. The liquid concentration in this mode is for low-concentration liquids. The intermittent preparation mode is for solutions that require ultra-high concentrations. At this time, it is necessary to ensure that the water level in the rapid stirring chamber does not exceed the overflow plate, so that the solution is fully dissolved in the maturation chamber. When the ultra-high concentration is reached, the valve of the connecting pipe is opened to allow the liquid in the maturation chamber to enter the pumping chamber.

[0036] According to an embodiment of the present invention, the bypass pipeline is controlled by the following formula: Among them, V 旁通 is the valve opening of the bypass pipe (unit: %, 0% means closed, 100% means fully open), C is the required concentration of the deicing agent solution (unit: %), C 高 is the high concentration threshold; The overflow damper is controlled by the following formula: Among them, V 溢流is the valve opening of the overflow damper (unit: %, 0% means closed, 100% means fully open); The flow rate of the deicing agent solution is calculated according to the following formula: Among them, Q 熟化 is the flow rate of the deicing agent solution flowing out of the maturation bin (unit: L / min), Q 泵送 It is the flow rate of the deicing agent solution entering the pumping bin (unit: L / min).

[0037] The embodiment of the present invention realizes automatic adjustment of the concentration of the deicing agent solution by accurately controlling the valve opening of the bypass pipeline and the overflow steel plate, thereby improving the efficiency and accuracy of the preparation process.

[0038] According to an embodiment of the present invention, the maturation bin includes: a maturation bin baffle, connected to the top of the maturation bin, used to separate multiple slow agitators; an overflow weir, located at the upper part of the maturation bin, and a weir groove filter screen is provided at the upper part of the overflow weir for filtering impurities.

[0039] In the embodiment of the present invention, a maturation bin baffle is provided inside the maturation bin to relatively separate the slow agitators to avoid mutual influence between the agitators. A weir filter is provided on the overflow weir of the maturation bin to filter impurities.

[0040] Figure 6 A cross-sectional view of a liquid storage tank and a conveying device according to an embodiment of the present invention is shown. As shown in the figure, according to an embodiment of the present invention, the liquid storage tank is connected to other liquid storage tanks through an overflow pipe, a vent pipe and a connecting pipe to form a series structure of multiple liquid storage tanks to increase the liquid storage capacity; the bottom of the high-speed agitator is set to an inverted cone shape to prevent the snow-melting agent particles from accumulating at the bottom and preventing the formation of a stirring dead zone.

[0041] In the embodiment of the present invention, the liquid storage tank is provided with an overflow pipe, a vent pipe and a connecting pipe. The connecting pipe serves to connect the storage modules in series, thereby increasing the liquid storage capacity.

[0042] According to an embodiment of the present invention, the de-icing agent preparation system also includes a conveying device, which includes: a valve group, used to adjust the flow direction of the de-icing agent solution to ensure uniform delivery; a water pump, connected to the liquid storage tank, used to convey the de-icing agent solution to a sprinkler truck; the de-icing agent preparation system also includes a reflux circulation pipe, one end of which is connected to the liquid storage tank, and the other end is connected back to the pumping bin, which is used to ensure that the de-icing agent solution in the liquid storage tank is self-circulated.

[0043] In the embodiment of the present invention, the conveying system of the storage module is composed of a water pump and its valve group, and a reflux circulation pipe is also provided to ensure that the liquid in the liquid storage tank can achieve self-circulation and prevent the deposition of undissolved snow-melting agent particles in the liquid storage tank. At the same time, the setting of the reflux pipe can prevent the water pump from being repeatedly started and stopped during continuous filling.

[0044] According to another embodiment of the present invention, a method for preparing an ice-melting agent is provided, comprising the following steps: using a loading device to transport a ton bag of ice-melting agent material; using a bag breaker to break the ton bag of ice-melting agent material and release the ice-melting agent particles; dissolving the released ice-melting agent particles in a stirring tank to obtain an ice-melting agent solution; and storing the ice-melting agent solution in a liquid storage tank.

[0045] According to an embodiment of the present invention, dissolving the released deicing agent particles in a stirring tank to obtain a deicing agent solution includes: supplying water to the bottom of the stirring tank through a water supply pipe; in a fast stirring bin connected to the water supply pipe, using a high-speed stirrer to quickly mix the deicing agent particles and water to obtain a deicing agent mixture; transferring the deicing agent mixture from the fast stirring bin to a maturation bin, and slowly stirring with one or more slow stirrers provided in the maturation bin to further dissolve the deicing agent particles to obtain the deicing agent solution; and pumping the deicing agent solution in the maturation bin to the liquid storage tank through a pumping bin.

[0046] The process flow of this device is as follows: the deicing agent particles in ton bags are transported to the feeding module by manual and forklift cooperation. The bag breaker feeding device in the feeding module lifts the ton bags and sends them to the bag breaker for bag breaking. After the bags are broken, the deicing agent falls into the mixing tank through the cone bucket at the bottom of the bag breaker. The mixing tank is equipped with a water supply pipe and a stirrer. After the deicing agent particles are dissolved in the mixing tank, they enter the storage module by pumping or pipe overflow. The finished deicing agent solution in the storage tank is pumped into the sprinkler truck.

[0047] The bag breaker device of the present invention is placed on a steel frame, the bag breaker and the spiral are respectively manufactured in a factory and transported to the site, and then the two are assembled on the steel frame on site, and the steel frame is fixed on a concrete foundation.

[0048] The bag breaker is equipped with an electric hoist and internal cutters.

[0049] The stirring module of the present invention is provided with a multi-step preparation bin, and the preparation bin includes: a rapid stirring bin, a maturation bin, and a pumping bin. The agitator matched with the rapid stirring bin has a high rotation speed, and the water supply of the stirring tank is also connected to the rapid stirring bin. After the rapid stirring bin is the maturation bin, a steel grating is provided between the maturation bin and the rapid stirring bin. The function of the steel grating is to divide the stirring tank. On the one hand, the snow melting agent particles and the tap water can be quickly blended and stirred. On the other hand, when the liquid level of the rapid stirring bin reaches a certain height, the solution can cross the partition and enter the maturation bin. A water hole is provided at the bottom of the steel grating for realizing the relative connection between the rapid stirring bin and the maturation bin. The maturation bin is provided with multiple slow agitators, and the purpose of the maturation bin is to further accelerate the dissolution of the snow melting agent soluble particles and the tap water medium. A maturation bin baffle is provided inside the maturation bin, the purpose of which is to relatively separate the slow agitators to avoid mutual influence between the agitators. After passing through the maturation bin, the liquid enters the pumping bin, and an overflow steel plate is provided between the pumping bin and the maturation bin. At the same time, a bypass pipe is also set between the maturation bin and the pumping bin. The purpose of this is to ensure that the preparation module can adopt two different preparation modes: continuous preparation mode and intermittent preparation mode. When the continuous preparation mode is adopted, the connecting pipe is closed, and the liquid solution enters the pumping bin through the overflow plate. In this mode, the liquid concentration is for low-concentration liquids. The intermittent preparation mode is for solutions that require ultra-high concentrations. At this time, it is necessary to ensure that the water inlet level of the rapid stirring bin does not exceed the overflow plate, so that the solution is fully dissolved in the maturation bin. When the ultra-high concentration is reached, the valve of the connecting pipe is opened to allow the liquid in the maturation bin to enter the pumping bin.

[0050] The bottom of the steel grating in the rapid mixing bin is provided with openings, and the function of the bottom openings is to ensure the relative connection between the rapid mixing bin and the maturation bin.

[0051] A weir filter is provided on the top of the overflow weir of the maturation bin to filter out impurities.

[0052] 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 liquid storage tank for storage.

[0053] The liquid storage tank is provided 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 to increase the liquid storage capacity.

[0054] The tank body of the preparation module is provided with an inverted cone, the purpose of which is to prevent the snow-melting agent material from accumulating at the bottom of the agitator and to prevent the existence of a mixing dead zone.

[0055] The storage module's delivery system consists of a water pump and its valve group, and is also equipped with a reflux circulation pipe to ensure that the liquid in the storage tank can achieve self-circulation and prevent the deposition of undissolved snow-melting agent particles in the storage tank. At the same time, the setting of the reflux pipe can prevent the water pump from being repeatedly started and stopped during continuous filling.

[0056] The present invention has the following advantages:

[0057] (1) Integrating the traditional deicing agent solution preparation process: The present invention integrates the traditional deicing agent solution preparation process, that is, integrating multiple production steps such as raw material preparation, solution preparation, and filling into a unified, 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.

[0058] (2) Enhance the applicability of the deicing agent solution preparation device: By setting two different preparation modes, low-concentration liquid can be obtained through the continuous preparation mode and high-concentration liquid can be obtained through the intermittent preparation mode according to actual needs. This is more flexible and significantly improves the adaptability and efficiency under different application requirements, thus better meeting the needs of different application scenarios.

[0059] (3) Improve the efficiency of deicing solution preparation: The rapid mixing bin, steel grating and maturation bin are set up to promote the rapid fusion and mixing of deicing agent particles and tap water and further accelerate dissolution. At the same time, the tank of the preparation module is equipped with an inverted cone to prevent the existence of a dead zone in stirring, so as to achieve full stirring and effectively improve the preparation efficiency of deicing solution.

[0060] (4) Improving the overall performance of the deicing agent preparation system: By integrating a reflux circulation pipe into the deicing agent preparation system, an efficient circulation flow system is constructed to maintain the uniform mixing and suspension state of the deicing agent solution, effectively preventing the undissolved deicing agent particles from settling at the bottom of the pool, avoiding equipment maintenance problems and solution performance degradation caused by sedimentation, and improving the overall performance of the entire system.
