Description

Technical Field

[0001] The invention belongs to the technical field of disinfectant production, and in particular relates to a non-corrosive chlorine-containing disinfectant for stainless steel equipment and a production process and a device. Background Art

[0002] Chlorine-containing disinfectants are highly effective disinfectants and are widely used in the food and daily chemical industries because of their high efficiency, economy and safety. They are often used for cleaning and disinfection of stainless steel equipment. Currently, non-corrosive chlorine-containing disinfectants often require sufficient mixing of raw materials during the production process, and a mixing device is generally used.

[0003] There are many types of existing mixing devices for disinfectant production. Among them, in the existing public documents, CN113318646A-A high-efficiency mixing device for disinfectant production is disclosed to be provided with a base, a concave slide is fixedly connected to the front side of the upper end surface of the base, a plurality of liquid bottles are placed on the upper end surface of the concave slide, and cranks that can rotate synchronously intermittently are respectively provided on the left and right sides of the rear end of the concave slide, and when the cranks rotate, a structure in which a plurality of liquid bottles slide synchronously to the left is formed; a ball valve with holes that matches the liquid bottle is installed at the lower end of the mixing barrel, and a bracket that matches the liquid bottle and can move up and down is installed at the lower end of the concave slide, and when the bracket moves downward, a structure in which the ball valve with holes rotates can be formed. Although it can be used for mixing in the production of disinfectants, the existing mixing device, when producing chlorine-containing disinfectants, will put multiple raw materials into a large mixing barrel at the same time. Because the addition positions of the raw materials are relatively concentrated, it is easy to cause excessive local concentration, and it is difficult to achieve sufficient and uniform mixing in a short time, thereby affecting the stability and consistency of product quality. In order to achieve more complete mixing, the mixing time is generally longer. However, mixing for too long a time will not only reduce the efficiency, but also lead to excessive mixing of the solution. In addition, the stirring method of some production devices is relatively simple. Relying only on simple mechanical stirring, it is impossible to effectively disperse and mix raw materials of different properties, which makes the mixing process time-consuming and inefficient, and cannot meet the needs of large-scale production. Moreover, the discharging method of many traditional chlorine-containing disinfectant production devices is relatively fixed, and usually can only be uniformly discharged through a single discharging port, which cannot meet the needs of different packaging forms and production processes. For example, when the mixed solution needs to be packaged, sampled for testing, or connected with other production links, the single discharging method will bring many inconveniences and reduce the controllability and flexibility of the production process. To this end, we provide a non-corrosive chlorine-containing disinfectant for stainless steel equipment and a production process and device to solve the above problems. Summary of the invention

[0014] At the same time, based on the above-mentioned component formula and production device, the present invention also provides a production process for preparing the non-corrosive chlorine-containing disinfectant, comprising the following steps: Mixing sodium hypochlorite, a corrosion inhibitor, a surfactant, a chelating agent and water to obtain a non-corrosive chlorine-containing disinfectant; In the present invention, the mixing temperature is preferably 20 to 35°C, more preferably 20 to 30°C, and most preferably 25 to 30°C; the mixing time is preferably 15 to 60 min, more preferably 15 to 45 min, and most preferably 20 to 30 min; In the present invention, mixing preferably includes: first mixing the chelating agent and water to obtain a first mixed solution; adding a surfactant to the first mixed solution to obtain a second mixed solution; adding a corrosion inhibitor to the second mixed solution to obtain a third mixed solution; adding sodium hypochlorite to the third mixed solution to obtain a fourth mixed solution.

Compared with putting the raw materials as a whole into a larger mixing barrel, by putting the raw materials into each independent inner tube component for mixing, the mixing amount is reduced, and the solutions in the inner tube components can be mixed more fully. In addition, the arrangement of the inner tube component can also pre-mix the solutions that need to be mixed collectively and then sequentially integrate them into the mixed solution for mixing, so that the raw materials can be mixed more fully.

[0022] The present invention can double-stir the solution in the mixing bin through the specific arrangement of the feed component and the inner tube component, so that the raw materials are fully and quickly mixed in the mixing bin, the mixing and dissolving efficiency is improved, and the stability and consistency of product quality are ensured.

[0049] The above-mentioned setting is specifically applied as follows: when mixing sodium hypochlorite, corrosion inhibitor, surfactant, chelating agent and water, if it is necessary to pour each raw material into each inner tube assembly 600 for mixing, at this time, the door slots 603 in each inner tube assembly 600 are all in a closed state, and then each hydraulic rod 530 is synchronously started by the switch, and the bottom frame plate 540 and each inner tube assembly 600 are driven to move downward synchronously through the action of the hydraulic rod 530, so that each inner tube assembly 600 is docked with each discharging mechanism 700, so that the discharging mechanism 700 closes the bottom of the inner tube assembly 600; thereafter, the baffle 443 is twisted, and the baffle 443 set vertically with the through groove 311 is twisted to be set horizontally with the through groove 311, and the baffle 443 of the feed assembly 400 will directly drop to the bottom after being freed from the restraint of the limit groove 312, and at this time, the ring seat 410 falls on the top surface of the barrel cover 300, and each outer feed single tube 420 will be inserted into each inner feed single tube one by one. 615, and then the raw materials are transported to the inner feed single tube 615 through the outer feed single tube 420, and then transported to the tube body 620 of the inner tube assembly 600 through the inner feed single tube 615. When loading, the servo motor 130 drives the driving gear 140 to rotate, and drives the gear ring 150 to rotate intermittently, so that the mixing barrel 200 as a whole rotates synchronously and intermittently, so that the outer feed single tube 420 in each part of the barrel cover 300 passes by the operator. During each intermittent period, the operator loads the outer feed single tubes 420 in the area in front of him in turn, and completes the loading operation of each inner tube assembly 600 at one time. After the loading is completed in the tube body 620 of each inner tube assembly 600, the second drive motor 612 located in the tube body 620 will be immediately started. Through the action of the second drive motor 612, each stirring shaft 613 can be driven to rotate synchronously, so that the raw materials in the tube body 620 can be mixed to complete the pre-mixing; After the pre-mixing is completed in the tube body 620 of each inner tube assembly 600, the gate slot 603 of the tube body 620 will automatically open, allowing the pre-mixed solution to flow into the mixing barrel 200, and then the stirring shaft 613 in the tube body 620 with each gate slot 603 opened can continue to stir the solution in the mixing barrel 200, so that each solution that flows into the mixing barrel 200 later can be fully mixed with the solution that flows into the mixing barrel 200 first, and when all the pre-mixed solutions have completed secondary mixing in the mixing barrel 200, the mixed solution is discharged through the discharge pipe 231; In addition, when the inner tube assembly 600 completes the loading operation, the stirring shaft 613 in the inner tube assembly 600 can be driven to rotate through the action of the second driving motor 612 to mix the raw materials in the tube body 620 until the preset time. When the solutions in each inner tube assembly 600 are fully mixed, the corresponding first solenoid valve 750 is opened, and then they are discharged into the collection bin 230 through their respective discharge main pipes 730, and then discharged through the discharge pipe 231; Alternatively, after the solutions in each inner tube assembly 600 are fully mixed, the corresponding No. 2 solenoid valve 760 is opened, and then the solutions are discharged separately through their respective single discharge pipes 770 .
