Technical Field

[0001] This utility model relates to the field of waste cleaning equipment, specifically to a multifunctional cleaning and disinfection device. Background Technology

[0002] The processing of raw materials for cold chain food requires frequent cleaning and disinfection. For example, foods rich in protein and fat, such as meat, aquatic products, and egg products, will generate various debris during processing. This debris can easily stick to surfaces and is extremely difficult to clean. Moreover, the low temperature and high humidity during processing also greatly increase the difficulty of cleaning and disinfection.

[0003] The cleaning and disinfection process usually requires manual spraying of sodium hydroxide solution first, which can saponify fats and hydrolyze protein deposits. Then, the dirt and cleaning agents are manually removed before disinfectant is sprayed to kill bacteria and disinfect. The whole process requires a lot of manpower and is complicated to operate.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 5As shown in the figure, this embodiment provides a multifunctional cleaning and disinfection device, including a body 1 and a motion system, a cleaning system 6, and a disinfection system 5 disposed on the body 1. The motion system drives the body 1 to move. Specifically, in this embodiment, the motion system includes a power wheel 401 and a steering wheel 402 disposed at the bottom of the body 1, and a drive mechanism driving the power wheel 401. The steering wheel 402 is used for steering, and the drive mechanism (such as a motor) drives the power wheel 401 to move. The cleaning system 6 cleans the dirt on the running path of the machine body 1. Specifically, in this embodiment, the cleaning system 6 includes a negative pressure box 601, a filter box 602, an exhaust fan 603, an exhaust channel 604, cleaning brushes 605, and a dirt inlet 606. The dirt inlet 606 is located at the bottom of the machine body 1. There are two cleaning brushes 605, which are respectively arranged on both sides in front of the dirt inlet 606. The inlet of the negative pressure box 601 is connected to the dirt inlet 606. The filter box 602 is arranged inside the negative pressure box 601. The outlet of the negative pressure box 601 is connected to the exhaust channel 604. The exhaust fan 603 is arranged inside the exhaust channel 604. During the movement of the machine body 1, the cleaning brush 605 sweeps the dirt on both sides to the dirt inlet 606. The dirt is sucked into the negative pressure box 601 through the dirt inlet 606 and filtered by the filter box 602. The air is drawn out from the exhaust channel 604 by the exhaust fan 603. Specifically, the negative pressure of the negative pressure box 601 is generated by the exhaust fan 603 drawing away the air.

[0028] The disinfection system 5 includes a brine storage tank 501 and a disinfection reaction tank 502. The brine storage tank 501 is used to store brine (i.e., sodium chloride solution). The outlet of the brine storage tank 501 is connected to the disinfection reaction tank 502 to supply raw materials (i.e., brine) to the disinfection reaction tank 502. The disinfection reaction tank 502 contains a sodium hypochlorite reaction chamber 507 and a sodium hydroxide reaction chamber 508. The machine body 1 has a spray outlet 505. The outlets of the sodium hypochlorite reaction chamber 507 and the sodium hydroxide reaction chamber 508 are connected to the spray outlet 505 of the machine body 1, and both the outlets of the sodium hypochlorite reaction chamber 507 and the sodium hydroxide reaction chamber 508 are equipped with a switch valve 503. Specifically, the outlets of the sodium hypochlorite reaction chamber 507 and the sodium hydroxide reaction chamber 508 are both connected to a liquid outlet pipe 506, which is connected to the spray outlet 505 of the machine body 1. The switch valve 503 is installed on the liquid outlet pipe 506.

[0029] For various meats, aquatic products, egg products, and other foods rich in protein and fat, stubborn stains can easily form on surfaces they come into contact with. In actual handling, the motion system is activated to first spray the sodium hydroxide solution prepared in the sodium hydroxide reaction chamber 508 onto the surface of the stains along the running path, allowing the sodium hydroxide solution to fully saponify the fats and hydrolyze the protein deposits. Afterwards, the motion system and cleaning system 6 are activated to remove the hydrolyzed contaminants. Simultaneously, while removing the contaminants, the sodium hypochlorite solution produced in the sodium hypochlorite reaction chamber 507 can be sprayed out for disinfection. Alternatively, the contaminants can be cleaned first, followed by another run to spray the sodium hypochlorite solution for disinfection.

[0030] The multi-functional cleaning and disinfection device provided in this application integrates cleaning and disinfection, and achieves mechanized operation, effectively saving labor and making it easy to operate.

[0031] In this embodiment, the sodium hypochlorite reaction chamber 507 has a first electrode 509, and the sodium hydroxide reaction chamber 508 has a second electrode 511. A cation exchange membrane 510 is disposed between the first electrode 509 and the second electrode 511. The first electrode 509 and the second electrode 511 are respectively connected to the positive and negative terminals of a direct current source. Specifically, the first electrode 509 is connected to the positive terminal of the direct current source and is a coated titanium anode or a titanium-plated platinum electrode. The second electrode 511 is connected to the negative terminal of the direct current source and is one of stainless steel, titanium, titanium alloy, titanium-plated platinum, or an electrode with a hydrogen evolution electrocatalytic active coating on its surface. The cation exchange membrane 510 is a polymer membrane containing ionic groups that has selective permeability to ions in solution. During operation, the ion exchange membrane only allows Na+ to pass through. + It allows a small amount of water molecules to pass through, but other ions have difficulty passing through.

[0032] Its preparation principle is as follows:

[0033] When the power is turned on, under the influence of the electric field, the negatively charged Cl... - H2O and Na move towards the first electrode 509, i.e., the anode, where they are positively charged. + H2O moves to the second electrode 511, i.e., the cathode, and during electrolysis, Cl- reacts in the sodium hypochlorite reaction chamber 507. - Discharge, 2Cl - -2e=Cl2 reacts to produce chlorine gas (Cl2), which dissolves in water and produces chlorine gas (Cl2). The reaction proceeds, resulting in a sodium hypochlorite solution in reaction chamber 507. Simultaneously, Na... + A small amount of water molecules are carried through the cation exchange membrane 510 and flow into the sodium hydroxide reaction chamber 508. Discharge occurs in the second electrode 511 reaction chamber, producing the reaction 2H₂O + 4e⁻ = H₂↑ + 2OH⁻. -Hydrogen gas (H2) and OH- are produced. - However, the remaining OH... - Due to the obstruction of the cation exchange membrane 510, it cannot move to the sodium hypochlorite reaction chamber 507, and thus gradually accumulates in the sodium hydroxide reaction chamber 508, forming a sodium hydroxide solution.

[0034] Sodium hypochlorite solution and sodium hydroxide solution can be prepared separately by electrolysis in the disinfectant reaction tank 502. The raw materials (salt water) are safe, easy to obtain, and low in cost.

[0035] Furthermore, the first electrode 509 and the second electrode 511 have a mesh structure, which facilitates solution flow.

[0036] The brine storage tank 501 and the disinfectant reaction tank 502 are located inside the machine body 1 and are integrated inside the machine body 1, which is more concise; the machine body 1 also has a feeding port that connects to the brine storage tank 501 to facilitate the addition of raw materials, and the feeding port is covered by a cover plate 2.

[0037] The on / off valves 503 installed at the outlets of the sodium hypochlorite reaction chamber 507 and the sodium hydroxide reaction chamber 508 are flow control valves, which can not only control opening and closing but also adjust the output flow rate after opening according to actual conditions. Specifically, the flow control valve adopts an existing valve body that can be used to adjust the flow rate in the prior art. Of course, in other embodiments, the on / off valve 503 can also be a valve body with only opening and closing functions, such as a solenoid valve.

[0038] The spray outlet 505 has two outlets. The outlets of the sodium hypochlorite reaction chamber 507 and the sodium hydroxide reaction chamber 508 are each connected to a separate spray outlet 505. That is, the sodium hypochlorite reaction chamber 507 and the sodium hydroxide reaction chamber 508 are each connected to a liquid outlet pipe 506. The two solutions are output separately and do not affect each other.

[0039] Both the outlet of the sodium hypochlorite reaction chamber 507 and the outlet of the sodium hydroxide reaction chamber 508 are equipped with a liquid temperature control system 504 to control the output liquid temperature respectively, ensuring that the sodium hypochlorite solution and sodium hydroxide solution are output at a suitable temperature, which is very suitable for operation in cold environments (such as cold storage). Specifically, the liquid temperature control system 504 has a controller, a heater, and a temperature sensor. The heater covers the surface of the outlet pipe (i.e., the liquid outlet pipe 506) to heat the liquid in the liquid outlet pipe 506. The temperature sensor senses the liquid temperature in the outlet pipe and outputs it to the controller, which controls the heater connected to it; thus, the output liquid temperature reaches a preset range. Of course, in other embodiments, the liquid temperature control system 504 may not be used, or the liquid temperature control system 504 may be located in other locations, such as on the disinfectant reaction tank 502.

[0040] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
