Description

Technical Field

[0001] The present invention relates to the technical field of deicing agent processing, and in particular to an environment-friendly deicing agent preparation device and method. Background Art

[0002] De-icing agent is a chemical used to melt snow. Its principle is to melt snow by lowering the melting temperature of ice and snow. The main components of de-icing agent are potassium acetate and chloride salts. Traditional de-icing agents are extracted from salt mines and contain a large amount of chlorine, such as sodium chloride, which is the main cause of death of trees, flowers and plants. Studies have found that chloride ions have a small radius and strong penetrating power. They can destroy the protective layer on the metal surface and cause pitting and stress corrosion cracking of the metal, which is very harmful to infrastructure and moving vehicles. The large amount of chloride ions contained in chloride salt-type de-icing agents will penetrate into the soil and block water penetration. Once the chlorine content in the roots of vegetation is too high, the branches and leaves will wither and die, destroying the green vegetation around the road. Therefore, non-chlorine de-icing agents are now used at a higher rate than traditional de-icing agents.

[0003] When preparing the existing non-chlorine snow-melting agents, it is sometimes necessary to use multiple liquid preparation tanks to mix multiple raw materials and then further mix the mixed raw materials. The liquid preparation tanks are generally large. When multiple liquid preparation tanks are placed separately to prepare the liquid, they occupy a large space, and multiple driving mechanisms are required to control the stirring and mixing of the raw materials in the multiple liquid preparation tanks, which increases the production cost. In order to further improve the purity and safety of the snow-melting agent and ensure its performance and environmental protection requirements, it is usually necessary to filter and remove impurities from the liquid snow-melting agent. However, the existing preparation device is often unable to continuously filter and remove impurities from the snow-melting agent containing impurities during use. After a period of use, the device needs to be shut down to clean the filter components in the device to ensure the filtering and impurity removal quality of the snow-melting agent, which will affect the preparation efficiency of the snow-melting agent.

[0045] The stirring assembly 9 is suitable for stirring and mixing the materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 at the same time;

[0046] The filtering component 11 is suitable for filtering and removing impurities from the prepared liquid snow-melting agent;

[0047] The cleaning component 12 is suitable for continuously cleaning the filter component 11;

[0048] The plurality of heating components 13 are suitable for regulating the temperatures of the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 respectively. When in use, the plurality of feeding pipes 6 are provided, and then the plurality of raw materials that need to be pre-mixed are first added to the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 respectively. According to needs, a corresponding number of middle mixing tanks 3 can be installed between the upper mixing tank 4 and the lower mixing tank 2 to meet the needs of preparing the snow melting agent. Under the action of the provided stirring component 9, a single first motor 14 can be used to control the plurality of stirring shafts 15 in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 to rotate simultaneously, so that the plurality of stirring blades 18 work simultaneously to stir and mix the raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 respectively. There is no need to use multiple driving components for stirring and mixing operations. At the same time, the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are stacked and arranged, which saves space and effectively reduces production costs. After the raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are respectively initially stirred and mixed, the plurality of stirring blades 18 are controlled to rotate simultaneously. The electromagnetic valve 8 allows the plurality of feed pipes 7 to pass through, thereby allowing the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 to be mixed and connected, and then the plurality of first valves 44 are controlled to allow the plurality of connecting pipes 40 to pass through. Under the control of the first liquid pump 42, the deicing agent raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are pumped into the mixing pipe 41, and then transported from the cover 5 to the upper mixing tank 4 through the guide pipe 43, so that the deicing agent raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are circulated and mixed, and the deicing agent raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are mixed and circulated. The rotation of the dry stirring blades 18 allows the raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 to be quickly and evenly mixed with each other; and when the raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are stirred and mixed, the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 can be heated and cooled by the plurality of heating components 13, the raw materials are heated when they are mixed to ensure the effect and efficiency of the stirring and mixing of the raw materials, and the raw materials are cooled after the mixing is completed to facilitate the subsequent processing of the deicing agent, thereby improving the preparation efficiency of the deicing agent;After the snowmelt is stirred and mixed, an impurity remover can be added to the upper mixing tank 4. Under the operation of the stirring component 9, the snowmelt and the impurity remover are stirred and mixed to ensure the contact effect of the impurity remover on the snowmelt, so that the impurities in the snowmelt form macromolecular solid particles or colloids. Under the cooperation of the second liquid pump 49, the discharge pipe 48 and the delivery pipe 51, the liquid snowmelt with impurities is transported to the processing box 10. The diverter box 53 can make the snowmelt with impurities flow evenly into the finished product cavity 21. At this time, under the control of the filter component 11, the filter conveyor belt 25 can filter the snowmelt with impurities, so that the filtered snowmelt finished product can flow into the finished product cavity 21 for storage, and the filtered The impurities can be conveyed to the impurity chamber 22 by the filter conveyor belt 25, so that some of the impurities can fall into the collection drawer 33, and under the control of the cleaning component 12, the filter conveyor belt 25 can be cleaned continuously during its movement, so as to prevent the impurities adhering to the filter conveyor belt 25 from re-entering the finished product chamber 21 and contaminating the finished deicing agent, thereby facilitating the filter conveyor belt 25 to continuously filter the finished deicing agent, without stopping to clean the filter component 11, ensuring the preparation efficiency of the deicing agent, and with the cleaning of the cleaning component 12, ensuring the filtering effect of the filter conveyor belt 25, and preventing blockage to affect the filtering of the deicing agent, thereby ensuring the quality of the finished deicing agent. ;

[0049] Optionally, the stirring assembly 9 includes a first motor 14 installed on the cover body 5, which is rotatably connected to a plurality of stirring shafts 15 in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2, respectively, a plurality of slots 16 are respectively opened on the tops of the plurality of stirring shafts 15, a plurality of plug rods 17 are respectively fixed to the bottoms of the plurality of stirring shafts 15, a plurality of stirring blades 18 are respectively fixed to the plurality of stirring shafts 15, a plurality of reinforcement seats 19 are respectively fixed to the bottoms of the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 and are rotatably connected to the plurality of stirring shafts 15, and a heavy mixing piece 20 is connected to the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2;

[0050] The output end of the first motor 14 is fixedly connected to the top of the stirring shaft 15 placed in the upper mixing tank 4;

[0051] The plurality of stirring shafts 15 are plug-connected to each other through a plurality of plug rods 17 and a plurality of slots 16. When in use, the first motor 14 is started, which can drive the plurality of stirring shafts 15 to rotate simultaneously, so that the plurality of stirring blades 18 can stir and mix the snow melting agent raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 respectively. Since two adjacent stirring shafts 15 are plug-connected through the plug rods 17 and the slots 16, when multiple middle mixing tanks 3 need to be installed between the upper mixing tank 4 and the lower mixing tank 2, it can be ensured that after each middle mixing tank 3 is connected and installed, the stirring shaft 15 inside can drive the stirring blades 18 to perform stirring operations, and the stirring shafts 15 in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2 are controlled to rotate simultaneously by the first motor 14 without the need for additional driving equipment, thereby effectively reducing costs.

[0052] Optionally, the filter assembly 11 includes a finished product chamber 21 and an impurity chamber 22 arranged in the processing box 10, a through slot 23 provided on the processing box 10 and used to connect the finished product chamber 21 and the impurity chamber 22, two transmission wheels 24 respectively rotating in the finished product chamber 21 and the impurity chamber 22, a filter conveyor belt 25 obliquely provided in the finished product chamber 21 and the impurity chamber 22 and sleeved on the two transmission wheels 24, a plurality of stoppers 26 fixed on the filter conveyor belt 25 at equal intervals, a plurality of filter holes 27 respectively provided on the plurality of stoppers 26, and a second motor 28 installed on the processing box 10;

[0054] The downwardly inclined end of the filter conveyor belt 25 is placed in the finished product chamber 21. When in use, the snow melting agent with impurities is transported to the processing box 10. At this time, the second motor 28 drives one of the transmission wheels 24 to rotate, and then the other transmission wheel 24 is synchronously rotated under the cooperation of the filter conveyor belt 25. When the snow melting agent with impurities falls on the filter conveyor belt 25, the snow melting agent after impurities are removed is collected and stored in the finished product chamber 21, and the impurities are transported to the impurity chamber 22 by the filter conveyor belt 25. Since the downwardly inclined end of the filter conveyor belt 25 is placed in the finished product chamber 21, The de-icing agent that falls on the filter conveyor belt 25 will not fall into the impurity chamber 22, and the several blocks 26 arranged on the filter conveyor belt 25 can ensure the retention effect of impurities on the filter conveyor belt 25, and ensure that the filter conveyor belt 25 can smoothly bring the impurities into the impurity chamber 22, and the several filter holes 27 can prevent the de-icing agent from being blocked by the blocks 26. Due to the movement of the filter conveyor belt 25, the de-icing agent can be filtered continuously, and it is convenient to cooperate with the cleaning component 12 to clean the filter conveyor belt 25, so as to avoid the filter conveyor belt 25 being blocked and ensure the filtering and cleaning effect of the de-icing agent.

When the filter component 11 filters the snow-melting agent with impurities, the transmission wheel 24 rotates, thereby driving the second toothed wheel 31 to rotate, and meshing and driving the first toothed wheel 30 through the toothed belt 32, driving the roller brush 29 to rotate, cleaning the surface of the filter conveyor belt 25, and brushing off impurities adhered to the surface of the filter conveyor belt 25, thereby preventing impurities from re-entering the finished product chamber 21 during the movement of the filter conveyor belt 25 and causing pollution to the prepared snow-melting agent.

[0056] Optionally, the heating component 13 includes an insulation sleeve 35 fixedly sleeved on the outside of the upper mixing tank 4, an assembly groove 55 opened on the outer wall of the upper mixing tank 4 and the inner wall of the insulation sleeve 35, a first heating coil 36 and a second heating coil 37 arranged in the assembly groove 55, a discharge pipe 38 connected to the upper end of the first heating coil 36 and the lower end of the second heating coil 37, and a liquid inlet pipe 39 connected to the lower end of the first heating coil 36 and the upper end of the second heating coil 37. This is the structure of the heating component 13 installed on the upper mixing tank 4, and the insulation sleeves 35 in the heating components 13 on the middle mixing tank 3 and the lower mixing tank 2 are respectively sleeved on the outside of the middle mixing tank 3 and the lower mixing tank 2. When the stirring component 9 stirs and mixes the snow melting agent raw materials in the upper mixing tank 4, the middle mixing tank 3 and the lower mixing tank 2, the liquid is supplied to the first heating coil 36 and the second heating coil 37 through the set liquid inlet pipe 39. The heated water is input into the second heating coil 37, and the heat is transferred to the upper mixing tank 4, the middle mixing tank 3 or the lower mixing tank 2 that needs to be heated through the water, so that the upper mixing tank 4, the middle mixing tank 3 or the lower mixing tank 2 is heated.
