It allows the interior of the production equipment to be effectively cleaned and disinfected without disassembling it. This cleaning method greatly improves production efficiency, reduces the risk of cross contamination, and ensures the hygiene standards of the production environment.

[0003] However, in the traditional automatic cleaning machine, during the cleaning process, after the cleaning liquid is circulated back and forth, the concentration of the cleaning liquid will be diluted, and as the cyclical cleaning operation proceeds, the cleaning effect on the relevant equipment will gradually decrease. Utility Model Content

[0004] In view of this, the utility model provides an automatic cleaning machine, which can realize efficient cleaning of the equipment to be cleaned through the cleaning device. When the concentration of the cleaning liquid is diluted and reduced, the concentrated acid stock solution in the concentrated acid tank can be introduced into the acid liquid tank through the concentrated acid pump, and the concentrated alkali stock solution in the concentrated alkali tank can be introduced into the alkali liquid tank through the concentrated alkali pump to realize the replenishment operation of the diluted cleaning liquid, so that the pH value of the cleaning liquid is restored to the level of efficient cleaning, which ensures the cleaning effect and greatly improves the cleaning efficiency. It solves the problem that in the traditional automatic cleaning machine, the concentration of the cleaning liquid will be diluted after the cleaning liquid is repeatedly used during the cleaning process, and the cleaning effect of the related equipment will gradually be reduced as the cyclic cleaning operation proceeds.

[0005] In order to solve the above technical problems, the utility model provides an automatic cleaning machine, comprising a hot water tank, a recovery water tank, an acid tank and an alkali tank, wherein the output ends of the hot water tank, the recovery water tank, the acid tank and the alkali tank are connected with a liquid outlet pipeline and a cleaning pump; the downstream side of the liquid outlet pipeline is respectively connected to the liquid return ports of the hot water tank, the recovery water tank, the acid tank and the alkali tank through a liquid return pipeline;

[0006] The cleaning device also includes a concentrated acid tank and a concentrated alkali tank. The liquid outlet of the concentrated acid tank is connected to the liquid inlet of the acid tank through a concentrated acid pump, and the liquid outlet of the concentrated alkali tank is connected to the liquid inlet of the alkali tank through a concentrated alkali pump. The liquid inlets of the concentrated acid tank and the concentrated alkali tank are connected to a soft water delivery pipeline. The utility model can realize efficient cleaning of the equipment to be cleaned through the cleaning device.

[0011] The liquid outlet pipeline and the soft water delivery pipeline are both 316L stainless steel pipes. Because 316L stainless steel contains higher nickel and molybdenum, it has better chloride corrosion resistance than conventional 304 stainless steel, and is especially suitable for handling cleaning fluids containing salt, acid or alkaline. During the CIP process, even when encountering various chemical cleaning agents, it can maintain good corrosion resistance and extend its service life. In addition, the surface of 316L stainless steel is smooth and not easy to adhere to pollutants, reducing the possibility of bacterial growth.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] like Figure 1 As shown: This embodiment provides an automatic cleaning machine, comprising a hot water tank 1, a recovery water tank 2, an acid tank 3 and an alkali tank 4, wherein the output ends of the hot water tank 1, the recovery water tank 2, the acid tank 3 and the alkali tank 4 are connected with a liquid outlet pipeline 6 and a cleaning pump 7; the downstream side of the liquid outlet pipeline 6 is connected to the liquid return ports of the hot water tank 1, the recovery water tank 2, the acid tank 3 and the alkali tank 4 respectively through a liquid return pipeline 8;

[0023] The hot water tank 1 is mainly used to store the heated clean water for the pre-rinsing, intermediate rinsing and final rinsing stages during the cleaning process. The hot water helps to soften and dissolve the residual dirt and improve the effect of the subsequent cleaning agent.

[0024] Hot water temperature control is critical. Appropriate high temperature can enhance cleaning ability, but excessive high temperature should be avoided to avoid damage to equipment.

[0025] The recycled water tank 2 is used to collect the water discharged during the cleaning process or the diluted cleaning liquid, which can be partially or completely recycled and reused after filtering and processing. Reducing water resource consumption and wastewater discharge is beneficial to environmental protection and cost saving. The recycled water may need to be tested and processed to ensure that it will not affect the cleaning effect or introduce new pollution when it is used again. Of course, the recycled water can also be used for pre-rinsing of some equipment to solve the water resource problem.

[0026] The acid tank 3 is used to store an acid cleaning agent, such as nitric acid or phosphoric acid, for removing inorganic salt scale, mineral deposits and microbial films. When in use, the concentration, temperature and contact time of the acid need to be precisely controlled to ensure effective cleaning without damaging the surface of the equipment.

[0027] The alkali tank 4 is used to store alkaline cleaning agents, such as sodium hydroxide or sodium phosphate, which are mainly used to remove grease, protein and other organic substances. Alkali cleaning is an important step in the CIP (cleaning in place) process, which can effectively decompose and suspend most of the dirt accumulated in the production process. It is also necessary to accurately control the use conditions of the alkali solution to achieve the best cleaning effect and equipment protection.

[0028] The downstream side of the liquid outlet pipeline 6 is connected to the liquid return ports of the hot water tank 1, the recovery water tank 2, the acid tank 3, and the alkali tank 4 respectively through the liquid return pipeline 8; the automatic cleaning device also includes a concentrated acid tank 9 and a concentrated alkali tank 10, the liquid outlets of the concentrated acid tank 9 and the concentrated alkali tank 10 are connected to the liquid inlets of the acid tank 3 and the alkali tank 4 respectively through the concentrated acid pump 11 and the concentrated alkali pump 12, and the liquid inlets of the concentrated acid tank 9 and the concentrated alkali tank 10 are connected to the soft water delivery pipeline 13. Through the soft water delivery pipeline 13, the acid and alkali in the concentrated acid tank 9 and the concentrated alkali tank 10 can be appropriately diluted to a degree suitable for supplementing the pH of the acid tank 3 and the alkali tank 4, so as to achieve precise control of acid and alkali supplementation.

[0029] The cleaning device also includes a concentrated acid tank 9 and a concentrated alkali tank 10. The liquid outlet of the concentrated acid tank 9 is connected to the liquid inlet of the acid tank 3 through a concentrated acid pump 11, and the liquid outlet of the concentrated alkali tank 10 is connected to the liquid inlet of the alkali tank 4 through a concentrated alkali pump 12. The liquid inlets of the concentrated acid tank 9 and the concentrated alkali tank 10 are connected to a soft water delivery pipeline 13. The utility model can realize efficient cleaning of the equipment to be cleaned through the cleaning device. When the concentration of the cleaning liquid is diluted and reduced, the concentrated acid stock solution in the concentrated acid tank 9 can be introduced into the acid tank 3 through the concentrated acid pump 11, and the concentrated alkali stock solution in the concentrated alkali tank 10 can be introduced into the alkali tank 4 through the concentrated alkali pump 12 to realize the replenishment operation of the diluted cleaning liquid, so that the pH value of the cleaning liquid is restored to the level of efficient cleaning, which ensures the cleaning effect while greatly improving the cleaning efficiency and the cleaning ability of the cleaning device.

[0030] The soft water delivery pipeline 13 is also connected to the liquid inlets of the acid tank 3 and the alkali tank 4. In this way, if the operator makes a mistake in operation and injects acid and alkali with too high concentration into the acid tank 3 and the alkali tank 4, resulting in excessive pH, the operator can directly inject water into the acid tank 3 and the alkali tank 4 through the soft water delivery pipeline 13 to dilute and remedy the situation, further improving the fault tolerance of pH adjustment of the cleaning equipment. In addition, the soft water delivery pipeline 13 can also be connected to the liquid inlets of the hot water tank 1 and the recovery water tank 2 to inject water. The utility model can inject water into the acid tank 3 or the alkali tank 4 through the soft water delivery pipeline 13, and can realize convenient and fast adjustment of the pH in the acid tank 3 and the alkali tank 4, which is more convenient.

[0031] The return liquid pipeline 8 is connected to the return liquid ports of the hot water tank 1, the recovery water tank 2, the acid tank 3, and the alkali tank 4 through the pipeline filter 14. The purpose of this is to intercept and remove impurities such as solid particles, residues, and damaged biofilms in the water or cleaning liquid when the corresponding cleaning liquid is refluxed. If these impurities are not intercepted, they may block the nozzle, valve 5 or leave residues on the surface of the equipment, affecting the cleaning effect. By filtering out large particles that may cause wear or damage to expensive production equipment, the pipeline filter 14 helps to extend the service life of the production equipment and reduce maintenance costs. According to the cleaning liquid characteristics and system requirements, the pore size of the filter (such as 20-100 mesh stainless steel wire mesh) can be flexibly selected to achieve the best filtering effect, while balancing the filtering efficiency and the system pressure drop. The utility model can realize the efficient filtering operation of the cleaning agent in the return liquid pipeline 8 through the pipeline filter 14, avoid the impurities mixed in the cleaning agent after cleaning from flowing into the hot water tank 1, the recovery water tank 2, the acid tank 3 or the alkali tank 4 through the return liquid pipeline 8, and ensure the purity of the recovered cleaning agent.

[0032] A heater is also provided on the liquid outlet pipeline 6, and the heater is a tubular heater 15. The utility model can quickly heat the cleaning liquid, such as hot water or chemical cleaning solution, to the required temperature (usually between 60°C and 80°C) through the tubular heater 15, accelerate the activity of the chemical components in the cleaning agent, and more effectively decompose and remove the dirt, protein, fat, carbohydrate and other deposits on the surface of the equipment. The tubular heater 15 can be easily integrated into the existing CIP system without making major changes to the production line, has strong adaptability, and is easy to implement and operate.

[0033] The liquid outlet pipeline 6 and the soft water delivery pipeline 13 are both 316L stainless steel pipes. Since 316L stainless steel contains higher nickel and molybdenum, it has better chloride corrosion resistance than conventional 304 stainless steel, and is particularly suitable for treating cleaning liquids with strong salt, acidity or alkalinity. During the CIP process, even if it encounters various chemical cleaning agents, it can maintain good corrosion resistance and extend its service life. In addition, the surface of 316L stainless steel is smooth and not easy to adhere to pollutants, which reduces the possibility of bacterial growth. During CIP cleaning, its smooth inner surface is convenient for cleaning liquid flushing, which can more effectively remove the residues left in the production process and ensure the hygiene standards of industries such as food processing or pharmaceuticals. Furthermore, the CIP process may involve the use of high-temperature steam or hot water. 316L stainless steel has good high temperature resistance and can withstand high temperature cleaning processes without deformation or damage, ensuring the efficiency and safety of cleaning. In addition, 316L stainless steel belongs to austenitic stainless steel and has very low magnetism, which is very important for some application scenarios that need to avoid magnetic contamination, especially in CIP cleaning of equipment related to pharmaceutical and precision instrument manufacturing industries. 316L stainless steel is safe and non-toxic, will not release harmful substances into the cleaning fluid or product, and meets the safety standards for food contact materials. It is an ideal material choice for cleaning scenarios such as food, beverages, and pharmaceuticals. 316L stainless steel has good compatibility with cleaning agents and disinfectants commonly used in CIP systems, and will not cause material damage or reduce cleaning effects due to chemical reactions.

[0034] The liquid outlet pipeline 6 and the soft water delivery pipeline 13 are both provided with valves 5, which are electrically controlled valves. The utility model can automatically control the opening and closing of the electrically controlled valves through a central control system, thereby realizing precise automation of cleaning without manual intervention, reducing the workload of operators and potential human errors.

[0035] The use of the utility model:

[0036] First of all, it should be made clear that the automatic cleaning machine involved in the utility model is mainly used for automatic and efficient cleaning operations on the equipment to be cleaned. The utility model takes the cleaning of food or beverage equipment as an example to explain its method of use in detail. It should be noted here that there are two liquid outlet pipelines 6, and the corresponding cleaning pumps 7, pipeline filters 14 and tubular heaters 15 are all two sets. The purpose of this is that when one of the pipeline filters 14 is blocked and needs to be cleaned, there is no need to stop the machine. You only need to close the electric control valve 5 on the blocked liquid outlet pipeline 6 and open the other liquid outlet pipeline 6 at the same time to continue the cleaning operation. At the same time, close the valves 5 on both sides of the pipeline filter 14 on the blocked liquid outlet pipeline 6, and then The pipeline filter 14 can be removed for cleaning or replacement, and the operation is more convenient and efficient. When the concentration of the cleaning liquid is diluted and reduced, the concentrated acid stock solution in the concentrated acid tank 9 can be introduced into the acid tank 3 through the concentrated acid pump 11, and the concentrated alkali stock solution in the concentrated alkali tank 10 can be introduced into the alkali tank 4 through the concentrated alkali pump 12 to achieve the replenishment operation of the diluted cleaning liquid, so that the pH value of the cleaning liquid is restored to the level of efficient cleaning, which solves the problem that in the traditional automatic cleaning machine, the concentration of the cleaning liquid will be diluted after the cleaning liquid is repeatedly circulated during the cleaning process, and the cleaning effect on related equipment will gradually decrease as the cyclic cleaning operation proceeds. While ensuring the cleaning effect, it also greatly improves the cleaning efficiency and improves the cleaning capacity of the cleaning device.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
