Description

Technical Field

[0001] This utility model relates to the field of ethylene glycol antifreeze, and in particular to an ethylene glycol heat preservation and filling device. Background Technology

[0002] In colder regions, existing technologies use fresh water as a cleaning solution when cleaning glass. However, when the ambient temperature is below freezing, ordinary fresh water will freeze and form a thin layer of ice when sprayed onto the outdoor glass, thus preventing proper cleaning.

[0003] However, washing glass with hot water can cause significant temperature changes that could lead to cracking or even irreversible damage. In such cases, ethylene glycol is needed. When ethylene glycol and water are mixed in a certain ratio, the freezing point of the solution decreases. For example, an antifreeze solution made of 40% ethylene glycol and 60% soft water has an antifreeze temperature of -25°C. When the antifreeze solution contains 50% ethylene glycol and 50% water, the antifreeze temperature is -35°C. This prevents the cleaning solution from forming a thin layer of ice on the glass, making it easier to clean outdoor glass.

[0004] However, existing technologies lack a mixing ratio detection mechanism when mixing ethylene glycol and water, which makes it impossible to adjust the ethylene glycol mixture solution to the appropriate concentration according to different weather temperatures. The amount of ethylene glycol added cannot be guaranteed, so it is necessary to improve the existing technology. Therefore, it is necessary to propose an ethylene glycol heat preservation and filling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ethylene glycol heat preservation and dispensing device to solve the problem mentioned above in the prior art that, when mixing ethylene glycol and water to make glass cleaning agent, there is a lack of a mixing ratio detection mechanism, which leads to the inability to adjust the ethylene glycol mixed solution to the appropriate concentration according to different weather temperatures, and the dispensing amount of ethylene glycol cannot be guaranteed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ethylene glycol heat-insulating filling device, comprising a base plate, wherein a push rod, a heat-insulating box, a mixing box, a second delivery pump, and a column are arranged sequentially from right to left on the top of the base plate; a storage tank is disposed inside the heat-insulating box; a partition plate is disposed in the middle of the storage tank to divide the interior of the storage tank into an ethylene glycol compartment and a clean water compartment; two support plates are fixedly disposed on the side of the heat-insulating box; a first delivery pump is disposed on the top of each of the two support plates; the input ends of the two first delivery pumps are connected to outlet pipes; and the two outlet pipes pass through the heat-insulating box respectively. The incubator extends into the interior of the ethylene glycol tank and the cleaning water tank. Flow meters and electric valves are installed on the outer rings of both outlet pipes. The output ends of the two first delivery pumps are connected to the mixing tank via first connecting pipes. An ethylene glycol concentration detector is installed on the mixing tank. The input end of the second delivery pump is connected to the mixing tank via a second connecting pipe. The output end of the second delivery pump is connected to the spray assembly located on the column via a hose. A controller is installed on the push rod. The first delivery pump, flow meter, electric valve, ethylene glycol concentration detector, and second delivery pump are all electrically connected to the controller.

[0007] Preferably, the inner wall of the insulated box is provided with an insulation layer, the bottom inner wall of the insulation layer is provided with a support block, the storage tank is fixed on the top of the support block, and there is a cavity between the storage tank and the insulation layer.

[0008] Preferably, the top of the insulation box is provided with a fan and a heater, the fan and the heater are connected to each other, the output end of the heater is connected to a diversion pipe located inside the insulation box through a third connecting pipe, the bottom of the diversion pipe is fixedly provided with a number of evenly distributed air outlets, the side of the insulation box is provided with a thermometer, and the thermometer, fan and heater are all electrically connected to the controller.

[0009] Preferably, the side of the insulated box is provided with two feeding pipes that are respectively connected to the ethylene glycol tank and the cleaning water tank.

[0010] Preferably, the spray assembly includes a chute fixedly installed inside the column, a cylinder is provided at the bottom of the chute, the telescopic end of the cylinder is connected to a slider adapted to the chute, a flow divider is provided on the side of the slider, and a plurality of nozzles are evenly distributed on the side of the flow divider, the hose and the slider are connected to each other, and the nozzles, the flow divider, the slider and the hose are interconnected.

[0011] Preferably, omnidirectional wheels are rotatably provided at each of the four corners of the bottom of the base plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. When using this device, the controller opens two electric valves, and then the two first delivery pumps are started. Ethylene glycol and cleaning water in the ethylene glycol tank and cleaning water tank are transported to the mixing tank through two outlet pipes and the first connecting pipe for mixing. The output volume of ethylene glycol and cleaning water is measured by two flow meters. After the output volume of ethylene glycol and cleaning water reaches their respective volumes, the associated electric valves are closed, thereby achieving precise output of ethylene glycol and cleaning water. This allows ethylene glycol and cleaning water to be mixed in a certain proportion to obtain an ethylene glycol mixed solution of appropriate concentration according to different weather temperatures. This solves the problem in the existing technology of mixing ethylene glycol and water to make glass cleaning agents, which lacks a mixing ratio detection mechanism, resulting in the inability to adjust the ethylene glycol mixed solution of appropriate concentration according to different weather temperatures and the inability to guarantee the amount of ethylene glycol added.

[0014] 2. This utility model, through the addition of ethylene glycol, starts the second delivery pump, allowing the mixture inside the mixing tank to pass through the second connecting pipe and hose, and then spray it onto the outdoor glass through the nozzle. This avoids the problem that when the ambient temperature is below freezing point, ordinary cleaning water will freeze and form a thin layer of ice on the outdoor glass, thus preventing the glass from being cleaned properly.

[0015] 3. When the temperature sensor detects that the outside temperature is low, the fan and heater are started, and hot air is then delivered into the distribution pipe through the third connecting pipe. The hot air is then evenly filled into the cavity through the air outlet, thereby heating the storage tank and keeping the ethylene glycol and cleaning water warm, thus preventing the ethylene glycol and cleaning water from condensing in cold weather.

[0016] 4. After starting the second delivery pump, the mixture is sprayed onto the outdoor glass through the nozzle. At the same time, the cylinder is started, which in turn drives the slider, the diverter plate and the nozzle to move, spraying the outdoor glass at different heights and improving the applicability of the device.

[0022] 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.

[0023] This utility model provides, for example Figures 1-4 The illustrated ethylene glycol heat preservation and filling device includes a base plate 1. From right to left, a push rod 25, a heat preservation box 2, a mixing box 17, a second delivery pump 19, and a column 20 are sequentially arranged on the top of the base plate 1. A storage tank 5 is housed inside the heat preservation box 2. A partition plate 6, dividing the interior of the storage tank 5 into an ethylene glycol compartment and a clean water compartment, is located in the middle of the storage tank 5. Two support plates are fixedly installed on the side of the heat preservation box 2. A first delivery pump 13 is installed on the top of each support plate. The input ends of both first delivery pumps 13 are connected to outlet pipes 14. The two outlet pipes 14 pass through the heat preservation box 2 and extend into the interior of the ethylene glycol compartment and the clean water compartment, respectively. Each of the two outlet pipes 14 is equipped with a flow meter 15 and an electric valve 16 at its outer ring. The output ends of the two first delivery pumps 13 are connected to the mixing tank 17 via a first connecting pipe. An ethylene glycol concentration detector 18 is installed on the mixing tank 17. The input end of the second delivery pump 19 is connected to the mixing tank 17 via a second connecting pipe. The output end of the second delivery pump 19 is connected to the spray assembly located on the column 20 via a hose 24. A controller 26 is installed on the push rod 25. The first delivery pump 13, the flow meter 15, the electric valve 16, the ethylene glycol concentration detector 18, and the second delivery pump 19 are all electrically connected to the controller 26.

[0024] When using this device, the controller 26 opens two electric valves 16, and then the two first delivery pumps 13 are started. Ethylene glycol and cleaning water in the ethylene glycol tank and cleaning water tank are transported to the mixing tank 17 through two outlet pipes 14 and the first connecting pipe for mixing. The flow rate of ethylene glycol and cleaning water is measured by two flow meters 15. After the ethylene glycol and cleaning water reach their respective flow rates, the electric valves 16 associated with each are closed, thereby achieving a precise flow rate of ethylene glycol and cleaning water. This allows ethylene glycol and cleaning water to be mixed in a certain proportion to obtain an ethylene glycol mixed solution of appropriate concentration according to different weather temperatures. This solves the problem in the existing technology of mixing ethylene glycol and water to make glass cleaning agents, which lacks a mixing ratio detection mechanism, resulting in the inability to adjust the ethylene glycol mixed solution of appropriate concentration according to different weather temperatures and the inability to guarantee the amount of ethylene glycol added.

[0025] This invention, through the addition of ethylene glycol and the activation of the second delivery pump 19, allows the mixture inside the mixing tank 17 to pass through the second connecting pipe and hose 24 and be sprayed out from the spray assembly to spray the outdoor glass. This avoids the problem that when the ambient temperature is below freezing, ordinary cleaning water will freeze and form a thin layer of ice on the outdoor glass, thus preventing it from cleaning the glass properly.

[0026] In addition, by monitoring the ethylene glycol concentration in the ethylene glycol mixture in real time through the ethylene glycol concentration detector, the mixing ratio of ethylene glycol and water can be determined, allowing for more precise detection of the amount of ethylene glycol added and improving the practicality of the device.

[0027] Considering that the severe cold weather would cause ethylene glycol and cleaning water to condense, an insulation layer 3 is provided on the inner wall of the insulation box 2. A support block 4 is provided on the inner wall at the bottom of the insulation layer 3. The storage tank 5 is fixed on the top of the support block 4. There is a cavity between the storage tank 5 and the insulation layer 3. A fan 8 and a heater 9 are provided on the top of the insulation box 2. The fan 8 and the heater 9 are connected to each other. The output end of the heater 9 is connected to the diversion pipe 10 located inside the insulation box 2 through a third connecting pipe. Several evenly distributed air outlets 11 are fixedly provided at the bottom of the diversion pipe 10. A thermometer 12 is provided on the side of the insulation box 2. The thermometer 12, the fan 8 and the heater 9 are all electrically connected to the controller 26.

[0028] Specifically, when the temperature sensor 12 detects that the external weather temperature is low, the fan 8 and heater 9 are started, and hot air is then delivered into the distribution pipe 10 through the third connecting pipe. The hot air is then evenly filled into the cavity through the air outlet 11, thereby heating the storage tank 5 and keeping the ethylene glycol and cleaning water warm, thus preventing the ethylene glycol and cleaning water from condensing in cold weather.

[0029] In addition, the installation of insulation layer 3 prevents heat loss and reduces the energy consumption of the device.

[0030] Furthermore, the spray assembly includes a chute fixedly installed inside the column 20. A cylinder 21 is installed at the bottom of the chute. The telescopic end of the cylinder 21 is connected to a slider that is compatible with the chute. A flow divider 22 is installed on the side of the slider. Several nozzles 23 are evenly distributed on the side of the flow divider 22. The hose 24 and the slider are connected to each other. The nozzles 23, the flow divider 22, the slider, and the hose 24 are interconnected. After the second delivery pump 19 is started, the mixture is sprayed onto the outdoor glass through the nozzles 23. At the same time, the cylinder 21 is started, which drives the slider, the flow divider 22, and the nozzles 23 to move, spraying outdoor glass at different heights and improving the applicability of the device.

[0031] Furthermore, the side of the insulated box 2 is equipped with two feeding pipes 7, which are respectively connected to the ethylene glycol tank and the cleaning water tank. Ethylene glycol and cleaning water are replenished to the ethylene glycol tank and the cleaning water tank through the feeding pipes 7.

[0032] Furthermore, casters are rotatably installed at the four corners of the bottom of the base plate 1, which facilitates the movement and use of the device.
