[0001] This utility model relates to the field of linen washing and treatment technology, specifically to a linen washing liquid preparation device. Background Technology
[0002] Linen detergent is widely used in the hotel and catering industries. Considering that linens with different levels of soiling, such as towels and sheets, require linen detergent in different formulations, corresponding linen detergent mixing devices have appeared on the market to ensure the cleaning effect of the linens.
[0003] Because linen detergent mixing devices generally require users to manually measure and add various detergents before mixing and feeding, the automation level of the devices is low. They cannot automatically calculate and mix detergents according to the type of linen and the degree of soiling, resulting in poor functionality. Therefore, we propose a new type of linen detergent mixing device to solve the above-mentioned defects. Utility Model Content

[0030] In use, users can pre-store various linen washing liquid mixing ratios via PLC controller 6. Subsequently, users only need to input the corresponding linen washing type into PLC controller 6, which will then control the liquid metering pumps 10 on the main detergent storage bottle 9, neutral detergent storage bottle 13, emulsifier storage bottle 14, bleach storage bottle 15, oxygen bleach storage bottle 16, or fabric softener storage bottle 17 to precisely extract the corresponding washing liquid into the mixing tank 4 via the metering feed fitting 8. The flow rate is controlled by the flow control valve 18 on the external tap water addition fitting 19, and the water inlet time is controlled by the timer 5. This allows for the automated addition of a fixed amount of tap water into the mixing tank 4. Specifically, for example, in a restaurant... For heavily stained linens such as tablecloths and kitchen towels, open the corresponding liquid metering pumps 10 on the main detergent storage bottle 9, emulsifier storage bottle 14, and bleach storage bottle 15 to dispense the main detergent, emulsifier, bleach, and tap water for mixing. For colored towels and bed sheets, which are linens that need to be protected from fading, open the corresponding liquid metering pumps 10 on the neutral detergent storage bottle 13, oxygen bleach storage bottle 16, and fabric softener storage bottle 17 to dispense the neutral detergent, oxygen bleach, fabric softener, and tap water for mixing. For ordinary towels, handkerchiefs, and face towels, which are not heavily soiled, open the corresponding liquid metering pumps 10 on the main detergent storage bottle 9 and fabric softener storage bottle 17 to dispense the main detergent, fabric softener, and tap water for mixing.
[0031] A mixing shaft 20 is movably connected to the inside of the mixing tank 4 via a bearing. A servo motor 12 connected to the mixing shaft 20 is installed at one end of the mixing tank 4.
[0032] When in use, starting the servo motor 12 can drive the mixing shaft 20 to rotate inside the mixing tank 4, which can realize the automatic stirring and mixing of different types of detergents and improve the subsequent washing effect.
[0033] The top of the mixing tank 4 is provided with a connecting pipe 7 that is inserted into the metering feed pipe 8. Both the connecting pipe 7 and the metering feed pipe 8 are provided with a rubber sealing layer.
[0034] The bottom ends of the main detergent storage bottle 9, neutral detergent storage bottle 13, emulsifier storage bottle 14, bleach storage bottle 15, oxygen bleach storage bottle 16, and fabric softener storage bottle 17 are all provided with magnetic locking posts 23 that engage with the frame 11. The outer wall of the magnetic locking post 23 is provided with a magnetic adsorption layer, which facilitates the positioning and disassembly of the main detergent storage bottle 9, neutral detergent storage bottle 13, emulsifier storage bottle 14, bleach storage bottle 15, oxygen bleach storage bottle 16, and fabric softener storage bottle 17 on the frame 11.
[0035] A scraper 21 is welded to the top of the mixing shaft 20, which contacts the inner wall of the mixing tank 4;
[0036] When in use, the servo motor 12 drives the mixing shaft 20 to stir and mix the washing liquid. The scraper 21 welded on the mixing shaft 20 and in contact with the inner wall of the mixing tank 4 can move accordingly to clean the inner wall of the mixing tank 4. This can solve the problem of the relatively viscous washing liquid product adhering to the inner wall of the mixing tank 4, causing pollution and waste, and further optimize the mixing effect.
[0037] A discharge pipe fitting 2 is welded to the middle position of the bottom of the mixing tank 4, and a solenoid valve 1 is installed on the discharge pipe fitting 2;
[0038] A vibration motor 3 is installed at the bottom of the mixing tank 4;
[0039] When in use, open the solenoid valve 1 installed on the discharge pipe fitting 2 to discharge the prepared and mixed washing liquid. At this time, the vibration motor 3 is turned on, which can generate vibration at the bottom of the mixing tank 4, which helps to discharge the washing liquid completely.
[0040] Both the water inlet fitting 19 and the outlet fitting 2 are equipped with flanges to facilitate external installation of the water inlet fitting 19 and the outlet fitting 2.
[0041] The working principle of this utility model is as follows: First, the user can pre-store various linen washing liquid mixing ratio data through the PLC controller 6. Subsequently, the user only needs to input the corresponding linen washing type through the PLC controller 6, so that the PLC controller 6 can control the liquid metering pump 10 on the main detergent storage bottle 9, neutral detergent storage bottle 13, emulsifier storage bottle 14, bleach storage bottle 15, oxygen bleach storage bottle 16, or fabric softener storage bottle 17 to accurately extract the corresponding washing liquid into the mixing tank 4 through the quantitative feeding pipe 8, and add it through the external tap water supply pipe. The flow control valve 18 on 19 regulates the inlet water flow, and the timer 5 controls the inlet water time. This allows for the automatic addition of a fixed amount of tap water inside the mixing tank 4. Specifically, for heavily soiled linens such as restaurant tablecloths and kitchen towels, the corresponding liquid metering pumps 10 on the main detergent storage bottle 9, emulsifier storage bottle 14, and bleach storage bottle 15 need to be opened to dispense the main detergent, emulsifier, bleach, and tap water for mixing. For colored towels and bed sheets, which require attention to prevent fading, the neutral detergent storage bottle 13 and oxygen bleach storage bottle 15 need to be opened. The liquid metering pumps 10 on bottles 16 and 17 dispense neutral detergent, oxygen bleach, fabric softener, and tap water for mixing. For less soiled linens such as ordinary towels, handkerchiefs, and face towels, the liquid metering pumps 10 on the main detergent and fabric softener storage bottles 9 and 17 can be opened to dispense main detergent, fabric softener, and tap water for mixing. Simultaneously, activating the servo motor 12 drives the mixing shaft 20 to rotate inside the mixing tank 4. This enables automated mixing of the different types of detergent solutions, improving the efficiency of subsequent washing. In addition to the washing effect, when the mixing shaft 20 stirs and mixes the washing liquid, the scraper 21 welded on the mixing shaft 20 and in contact with the inner wall of the mixing tank 4 can move accordingly to clean the inner wall of the mixing tank 4. This can solve the problem of the relatively viscous washing liquid product adhering to the inner wall of the mixing tank 4, causing pollution and waste, and further optimize the mixing effect. Finally, the solenoid valve 1 installed on the discharge pipe 2 can be opened to discharge the mixed washing liquid. At this time, the vibration motor 3 is turned on, which can generate vibration force at the bottom of the mixing tank 4, which helps to fully discharge the washing liquid.
