Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to a pre-washing device. Background Technology

[0002] In various industries, including industrial production, daily life, and healthcare, there are scenarios where cleaning is necessary. Examples include cleaning tobacco tar, household or commercial tableware, medical supplies, oil tanks, and food. Cleaning methods mainly include a main wash, a rinsing stage, and a drying stage. In some applications, to ensure thorough cleaning, improve efficiency, and reduce the workload on the cleaning machine, a pre-wash may be performed before the main wash stage, as needed.

[0003] A Chinese patent discloses a fruit pre-rinsing device, including an overlapping net between an inspection table and a fruit washing machine. A water spray pipe is located above the overlapping net, with spray holes on one side facing the overlapping net. A water collection tank is located below the overlapping net, and the bottom of the water collection tank is connected to the spray pipe via a water inlet pipe and a circulating pump located within the water inlet pipe. A filter screen is fixed to the top of the water collection tank, and the aperture of the filter screen is no larger than the aperture of the overlapping net. This invention uses the aforementioned fruit pre-rinsing device. By setting a pre-rinsing device between the inspection table and the fruit washing machine, impurities adhering to the fruit peel can be flushed off, reducing the cleaning pressure on the subsequent washing machine. However, this pre-rinsing device only performs a simple rinse of the fruit with water, resulting in limited cleaning ability. Furthermore, its cleaning ability is significantly insufficient when dealing with stubborn dirt such as oil stains and clumps. The water containing oil stains cannot be directly recycled after cleaning, thus limiting its cleaning capabilities. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing pre-washing equipment, such as limited cleaning capacity and small number of objects to be cleaned, and to provide a pre-washing device that can perform high-quality pre-washing on different types of objects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A pre-washing device is provided, comprising:

[0007] A pre-washing tank is used to hold items to be washed, and the top of the pre-washing tank is open.

[0008] A filter tank is installed inside the pre-wash tank. The top of the filter tank is open, and the open surface of the filter tank is lower than or flush with the open surface of the pre-wash tank.

[0009] A micro-nano bubble generator is installed next to the pre-wash tank. The input end of the micro-nano bubble generator is connected to the filter tank, and the output end of the micro-nano bubble generator is connected to the pre-wash tank.

[0010] The first floating debris discharge channel is located inside the filter tank. The first floating debris discharge channel is provided with an overflow port. The overflow port is located at a height higher than the bottom surface of the filter tank and lower than the open surface of the filter tank.

[0011] An agitation device is installed in the pre-washing tank to agitate the water in the pre-washing tank into a vortex and / or turbulent state.

[0012] The recycling system includes a first recycling water pipe connected at one end to a filter tank and at the other end to a pre-wash tank, and a pumping device for conveying water in the first recycling water pipe.

[0013] In this setup, when pre-washing is required, the user first places the items to be cleaned into the pre-wash tank and adds water. Simultaneously, an agitator operates, causing the water in the pre-wash tank to ripple, thus separating oil and other dirt from the items. The denser, water-insoluble dirt settles to the bottom of the pre-wash tank, while less dense dirt, such as oil, floats to the surface. When the water level in the pre-wash tank is higher than that in the filter tank, the water on the surface flows into the filter tank, removing floating contaminants. When the water level in the filter tank reaches the overflow outlet, the floating contaminants at the top are discharged from the overflow outlet. A micro-nano bubble generator and a recovery system then extract the cleaner water from the bottom of the filter tank. After the generator produces micro-nano bubbles, they are fed back into the pre-wash tank to assist in cleaning. When the micro-nano bubbles contract, the charge density of the double layer increases rapidly. When the bubbles burst, the drastic change of the disappearance of the gas-liquid interface releases the energy stored in the high concentration of positive and negative ions on the interface. At this time, a large number of hydroxyl radicals can be generated, thereby increasing the activity of the water and improving the cleaning effect of the water. Moreover, when the bubbles burst, they generate jets that physically impact the dirt on the surface of objects, turning oil and other dirt that are difficult to dissolve in water into small droplets, which are easy to emulsify with the water. The pumping device in the recycling system pumps most of the relatively clean water in the filtration tank back into the pre-wash tank, where it re-participates in the circulation to carry away pollutants, thereby achieving the purpose of water conservation and environmental protection.

[0014] Preferably, the device also includes an ozone generator, the output of which is connected to the input of the micro / nano bubble generator.

[0015] In this configuration, the ozone generator produces ozone that dissolves in the water, giving the water a disinfection and sterilization function. However, the solubility of ozone directly in water is limited. By introducing ozone into the micro-nano bubble generator, the micro-nano bubble generator produces a large number of ozone-containing micro-nano bubbles in the water, thereby improving the water's ability to absorb ozone, increasing the ozone concentration in the water, and further improving the disinfection and sterilization effect of the water.

[0016] Preferably, the micro / nano bubble generator includes a self-priming pump and a mixing chamber. The self-priming pump is used to create negative pressure in the mixing chamber, and the input end of the mixing chamber is connected to the filter pool and the ozone generator, respectively.

[0017] With this setup, because the pressure inside the filtration tank is relatively low, a self-priming pump is needed to generate negative pressure to draw water from the depressurization tank to the mixing chamber. Ozone and water mix in the mixing chamber, and the water repeatedly shears and breaks down the ozone through high-speed swirling and hydraulic shearing. This causes some ozone to mix in the water and generate ozone micro-nano bubbles, while some ozone dissolves directly in the water, thus forming ozone-rich water. Increasing the ozone content helps to improve the bactericidal effect of ozone, thereby improving the cleaning effect of the water.

[0018] Preferably, the agitation device includes a plurality of air pipes disposed in the pre-washing tank and an air supply device disposed outside the pre-washing tank and connected to the plurality of air pipes, wherein each air pipe is provided with a plurality of air holes.

[0019] With this setup, the air supply device generates a large number of large bubbles from the air holes by supplying air to the air pipe. As the large bubbles rise in the pre-washing tank, they expand and burst, or collide and burst directly with the surface of the object to be cleaned. The bursting process generates disturbance, causing water to ripple. The energy generated during the bursting process can promote the separation of dirt from the object to be cleaned, thereby improving the cleaning effect.

[0020] Preferably, the pre-wash tank is provided with a device chamber, the device chamber is provided with a heating element, the top opening of the device chamber is flush with the bottom of the pre-wash tank, and a filter screen is provided at the top opening of the device chamber.

[0021] With this configuration, the heating element can heat the water in the pre-washing tank, thereby improving the water's ability to dissolve dirt and enhancing the cleaning effect of the pre-wash. The device chamber is located at the bottom of the pre-washing tank and is blocked by a filter screen, so it will not affect the water flow. When the heating element heats the nearby water, the hot water will rise naturally, and the surrounding cold water will replenish it, forming a circulation, which is conducive to achieving uniform heating of the water in the pre-washing tank.

[0022] Preferably, the pre-washing tank is further submerged and provided with a drainage chamber, the drainage chamber being provided with a second floating debris discharge channel, the top of the second floating debris discharge channel being provided with a second overflow port, the height of the second overflow port being higher than the first overflow port and lower than the opening of the pre-washing tank, and a filter screen being provided around the second floating debris discharge channel.

[0023] With this setup, under normal pre-washing conditions, the high-pressure water gun in the pre-washing tank continuously sprays water onto the items to be cleaned. The rising water in the pre-washing tank falls into the filter tank and is then discharged from the first overflow outlet in the filter tank, maintaining a dynamic balance of water level. When the water volume entering the pre-washing tank exceeds the water volume discharged from the first overflow outlet, the water level will rise until it overflows the filter tank. When it reaches the height of the second overflow outlet, the excess water will be discharged from the second overflow outlet, which can also achieve the effect of removing floating objects and prevent the water level in the pre-washing tank from overflowing due to excessive height.

[0024] Preferably, the bottom of the filter tank is provided with a first drain outlet that can be opened and closed, and the bottom of the drainage chamber is also provided with a second drain outlet that can be opened and closed. Both the first floating material discharge channel and the second floating material discharge channel are cylindrical structures. The bottom of the first floating material discharge channel is inserted into the first drain outlet, and the bottom of the second floating material discharge channel is inserted into the second drain outlet.

[0025] With this setup, after cleaning is complete, the first or second floating debris discharge channel can be removed to open the first and second drain outlets respectively, thereby draining the accumulated water in the filter tank and pre-wash tank. When the first floating debris discharge channel is inserted into the first drain outlet and the second floating debris discharge channel is inserted into the second drain outlet, overflow outlet structures of different heights can be formed respectively, thereby achieving selective sewage discharge function.

[0026] Preferably, it further includes a first water treatment system, the input of which can be connected to an external water source, and the output of which is connected to the input of the pre-washing tank.

[0027] Preferably, the first water treatment system includes a water weak alkalization module, a water magnetization module that can magnetize water to form small molecular clusters of water with a half-width of less than 60 Hz, and a water flow channel.

[0028] Preferably, the water alkalinization module includes a housing with an inlet and an outlet, and a filter media encapsulated within the housing that can turn water into a weak alkaline state; the water magnetization module includes a first tube with magnetic conductivity, and a magnet disposed on the first tube for forming a magnetic field in the region of the first tube, the first tube having an inlet and an outlet; the water flow channel includes an inlet and an outlet;

[0029] The water weak alkalization module and the water magnetization module are sequentially arranged between the inlet and outlet of the water flow channel along the water flow direction.

[0030] The inlet of the water weak alkalization module is connected to the water flow channel, the outlet of the water weak alkalization module is connected to the inlet of the first tube of the water magnetization module, and the outlet of the first tube of the water magnetization module is connected to the outlet of the water flow channel.

[0031] Preferably, the magnet includes at least one magnet group arranged along the axial direction of the first tube, each magnet group including two magnets, the magnets being fixedly disposed on the outer surface of the first tube, and the opposite magnetic poles of the two magnets facing each other;

[0032] The magnetic field between the two magnets has a force of 5000-6000 Gauss;

[0033] When there are multiple magnet groups, the arrangement of adjacent magnet groups is such that their orthogonal projections in the axial direction of the first tube are perpendicular to each other.

[0034] Preferably, the water magnetization module further includes a shell with a sealed cavity, the first tube passing through the sealed cavity of the shell, the sealed cavity being filled with a rare earth filler having thermal conductivity and magnetic locking properties, and a heating component and a sensor for monitoring temperature being provided in the area surrounding the first tube.

[0035] Preferably, a rinsing water gun is also provided above the pre-washing tank, and the input end of the rinsing water gun is connected to the output end of the first water treatment system.

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] (1) By setting up a micro-nano bubble generator and agitation device, water with micro-nano bubbles is generated. The agitation device increases the impact of the water on the surface of the object to be cleaned, thereby improving the water's cleaning ability and achieving a high-quality cleaning effect.

[0038] (2) By setting up a filter pool, a recycling system and a first floating matter discharge channel, the classification and treatment of dirt and grime on the object to be cleaned by flushing it from the top and cleaning it from the bottom is realized, ensuring the relative cleanliness of the circulating water and improving the pre-washing quality.

[0039] (3) By combining the micro-nano bubble generator with the ozone generator, the ozone content in the water body is increased, the sterilization and disinfection ability of the water body is improved, and the cleaning effect is further improved. Attached Figure Description

[0048] Example 1

[0049] like Figures 1 to 4 The first embodiment of the pre-washing device of this utility model is shown, comprising:

[0050] Pre-wash tank 1 is used to hold items to be washed, and the top of pre-wash tank 1 is open.

[0051] Filter tank 2 is installed inside pre-wash tank 1. The top of filter tank 2 is open. The open surface of filter tank 2 is lower than or flush with the open surface of pre-wash tank 1.

[0052] The micro-nano bubble generator 3 is located next to the pre-wash tank 1. The input end of the micro-nano bubble generator 3 is connected to the filter tank 2, and the output end of the micro-nano bubble generator 3 is connected to the pre-wash tank 1.

[0053] The first floating debris discharge channel 21 is set inside the filter tank 2. The first floating debris discharge channel 21 is provided with an overflow port. The overflow port is set at a height higher than the bottom surface of the filter tank 2 and lower than the open surface of the filter tank 2.

[0054] A stirring device 4 is installed in the pre-washing tank 1 to agitate the water in the pre-washing tank 1 into a vortex and / or turbulent state.

[0055] The recycling system 5 includes a first recycling water pipe 51 connected at one end to the filter tank 2 and at the other end to the pre-wash tank 1, and a pumping device 52 for transporting water in the first recycling water pipe 51.

[0056] With this setup, when pre-washing is required, the user first places the items to be cleaned into the pre-wash tank 1 and adds water. Simultaneously, the agitator 4 operates, causing the water in the pre-wash tank 1 to ripple, thus separating oil and other dirt from the items. The denser, water-insoluble dirt settles to the bottom of the pre-wash tank 1, while less dense dirt, such as oil, floats to the surface. When the water level in the pre-wash tank 1 is higher than that in the filter tank 2, the water on top of the pre-wash tank 1 flows into the filter tank 2, thus removing floating pollutants. When the water level in the filter tank 2 reaches the overflow outlet height, the floating pollutants at the top of the water are discharged from the overflow outlet. The micro-nano bubble generator 3 and the recovery system 5 then extract the cleaner water from the bottom of the filter tank 2. After generating micro-nano bubbles, the micro-bubble generator 3 inputs them back into the pre-wash tank to assist in cleaning. When the micro-nano bubbles contract, the charge density of the double layer increases rapidly. When the bubbles burst, the drastic change of the disappearance of the gas-liquid interface releases the energy stored in the high concentration of positive and negative ions on the interface. At this time, a large number of hydroxyl radicals can be generated, thereby increasing the activity of the water and improving the cleaning effect of the water. Moreover, when the bubbles burst, they generate jets, which physically impact the dirt on the surface of objects, turning oil and other dirt that are difficult to dissolve in water into small droplets, which are easy to emulsify with the water. The pumping device 52 in the recycling system 5 pumps most of the relatively clean water in the filter tank 2 back to the pre-wash tank 1, re-participating in the circulation to carry away pollutants, thereby achieving the purpose of water conservation and environmental protection.

[0057] As one embodiment of this utility model, it also includes an ozone generator 6, the output end of which is connected to the input end of the micro-nano bubble generator 3.

[0058] With this setup, the ozone generator 6 generates ozone that dissolves in the water, giving the water a disinfection and sterilization function. However, the solubility of ozone directly in water is limited. By introducing ozone into the micro-nano bubble generator 3, the micro-nano bubble generator 3 generates a large number of ozone-containing micro-nano bubbles in the water, thereby improving the water's ability to absorb ozone, increasing the ozone concentration in the water, and further improving the disinfection and sterilization effect of the water.

[0059] As one embodiment of the present invention, the micro-nano bubble generator 3 includes a self-priming pump 31 and a mixing chamber 32. The self-priming pump 31 is used to create a negative pressure in the mixing chamber 32. The input end of the mixing chamber 32 is connected to the filter tank 2 and the ozone generator 6 respectively.

[0060] With this setup, since the pressure inside the filter tank 2 is relatively low, the self-priming pump 31 needs to generate negative pressure to draw water from the pressure-reducing tank to the mixing chamber 32. Ozone and water mix in the mixing chamber 32. The water in the mixing chamber 32 repeatedly shears and breaks down the ozone through high-speed swirling and hydraulic shearing, causing some ozone to mix in the water and generate ozone micro-nano bubbles. Some ozone is also dissolved directly in the water in a water-soluble manner, thus forming an ozone-rich water body. Increasing the ozone content helps to improve the bactericidal effect of ozone, thereby improving the cleaning effect of the water body.

[0061] As one embodiment of the present invention, the stirring device 4 includes a plurality of air pipes 41 disposed in the pre-washing tank 1 and an air supply device 42 disposed outside the pre-washing tank 1 and connected to the plurality of air pipes 41, and a plurality of air holes are provided on each of the air pipes 41.

[0062] With this setup, the air supply device 42 supplies air to the air pipe 41, generating a large number of large bubbles from the air holes. As the large bubbles rise in the pre-washing tank 1, they expand and burst, or collide and burst directly with the surface of the object to be cleaned. The bursting process generates disturbance, causing water to ripple. The energy generated during the bursting process can promote the separation of dirt from the object to be cleaned, thereby improving the cleaning effect.

[0063] As one embodiment of this utility model, the pre-washing tank 1 is provided with a device chamber 11, the device chamber 11 is provided with a heating element 12, the top opening of the device chamber 11 is flush with the bottom of the pre-washing tank 1, and a filter screen is provided at the top opening of the device chamber 11.

[0064] With this configuration, the heating element 12 can heat the water in the pre-wash tank 1, thereby improving the water's ability to dissolve dirt and enhancing the cleaning effect of the pre-wash. The device chamber 11 is located at the bottom of the pre-wash tank 1 and is blocked by a filter screen, so it will not affect the water flow. When the heating element 12 heats the nearby water, the hot water will rise naturally, and the surrounding cold water will replenish it, forming a circulation, which is conducive to achieving uniform heating of the water in the pre-wash tank 1.

[0065] Example 2

[0066] The following is a second embodiment of a pre-washing device of the present invention. This embodiment is similar to embodiment 1, except that it also provides a drainage chamber 13 and further defines the first floating object discharge channel 21.

[0067] As one embodiment of the present invention, the pre-washing tank 1 is further provided with a drainage chamber 13, and a second floating object discharge channel 14 is provided in the drainage chamber 13. A second overflow port 141 is provided at the top of the second floating object discharge channel 14. The height of the second overflow port 141 is higher than that of the first overflow port 211 and lower than that of the opening of the pre-washing tank 1. A filter screen is provided around the second floating object discharge channel 14.

[0068] With this setup, under normal pre-washing conditions, the high-pressure water gun in the pre-wash tank 1 will continuously spray water onto the items to be cleaned in the pre-wash tank 1. The rising water in the pre-wash tank 1 falls into the filter tank 2 and is then discharged from the first overflow port 211 in the filter tank 2, maintaining a dynamic balance of the water level. When the amount of water entering the pre-wash tank 1 is greater than the amount of water discharged from the first overflow port 211, the water level will rise until it overflows the filter tank 2. When it reaches the height of the second overflow port 141, the excess water will be discharged from the second overflow port 141, which can also achieve the effect of removing floating objects and prevent the water level in the pre-wash tank 1 from overflowing due to excessive height.

[0069] As one embodiment of this utility model, the bottom of the filter tank 2 is provided with a first drain outlet that can be opened and closed, and the bottom of the drain chamber 13 is also provided with a second drain outlet that can be opened and closed. The first floating object discharge channel 21 and the second floating object discharge channel 14 are both cylindrical structures. The bottom of the first floating object discharge channel 21 is inserted into the first drain outlet, and the bottom of the second floating object discharge channel 14 is inserted into the second drain outlet.

[0070] With this setup, after cleaning is complete, the first floating debris discharge channel 21 or the second floating debris discharge channel 14 can be removed to open the first and second drain outlets respectively, thereby draining the accumulated water in the filter tank 2 and the pre-wash tank 1. When the first floating debris discharge channel 21 is inserted into the first drain outlet and the second floating debris discharge channel 14 is inserted into the second drain outlet, overflow outlet structures of different heights can be formed respectively, thereby achieving selective sewage discharge function.

[0071] Example 3

[0072] The following is a third embodiment of a pre-washing device of the present invention. This embodiment is similar to embodiment 1, except that it also includes a first water treatment system 7.

[0073] As one embodiment of this utility model, it also includes a first water treatment system 7, the input end of which can be connected to an external water source, and the output end of the first water treatment system 7 is connected to the input end of the pre-washing tank 1.

[0074] As one embodiment of the present invention, the first water treatment system 7 includes a water weak alkalization module 71, a water magnetization module 72 that can magnetize water to form small molecular clusters of water with a half-width of less than 60Hz, and a water flow channel.

[0075] As one embodiment of this utility model, the water weak alkalinization module 71 includes a shell with an inlet and an outlet, and a filter material encapsulated in the shell that can turn water into weak alkalinity; the water magnetization module 72 includes a first tube with magnetic conductivity, a magnet disposed on the first tube for forming a magnetic field in the region of the first tube, the first tube having an inlet and an outlet; and the water flow channel including an inlet and an outlet.

[0076] The water weak alkalization module 71 and the water magnetization module 72 are sequentially arranged between the inlet and outlet of the water flow channel along the water flow direction.

[0077] The inlet of the water weak alkalization module 71 is connected to the water flow channel, the outlet of the water weak alkalization module 71 is connected to the inlet of the first pipe of the water magnetization module 72, and the outlet of the first pipe of the water magnetization module 72 is connected to the outlet of the water flow channel.

[0078] As one embodiment of the present invention, the magnet includes at least one magnet group arranged along the axial direction of the first tube, each magnet group including two magnets, the magnets being fixedly disposed on the outer surface of the first tube, and the opposite magnetic poles of the two magnets facing each other.

[0079] The magnetic field between the two magnets has a force of 5000-6000 Gauss;

[0080] When there are multiple magnet groups, the arrangement of adjacent magnet groups is such that their orthogonal projections in the axial direction of the first tube are perpendicular to each other.

[0081] As one embodiment of the present invention, the water magnetization module 72 also includes a shell with a sealed cavity, a first tube passing through the sealed cavity of the shell, the sealed cavity being filled with a rare earth filler having thermal conductivity and magnetic locking properties, and a heating component and a sensor for monitoring temperature being provided in the area surrounding the first tube.

[0082] In this configuration, the main function of the water weak alkalization module 71 is to make the water weakly alkaline, while the main function of the water magnetization module 72 is to magnetize the water to form small molecular clusters. During the process of water passing through the weak alkalization module 71 and the water magnetization module 72, the dipole moments of the two H1O bonds of the water molecules cannot cancel each other out, and the centers of positive and negative charges do not coincide. The entire molecule has high polarity. Utilizing the principle of attraction between the polarity of water molecules and the positive and negative charges of oil stains, the water molecules easily entrain and carry away the oil stains, thus achieving the purpose of cleaning stains without detergent.

[0083] As one embodiment of this utility model, a rinsing water gun 15 is also provided above the pre-washing tank 1, and the input end of the rinsing water gun 15 is connected to the output end of the first water treatment system 7.
