The device has a high degree of automation and can realize automatic water addition and water shutoff. By installing the humidity sensor 33, the detection end on the humidity sensor 33 is installed inside the processing tank 1. When adding raw materials, the detection end is inside the powder so as to monitor the humidity inside the powder at the upper end of the processing tank 1, which is convenient for automatic water addition. At the same time, it can also avoid excessive water addition, which causes the powder to become thinner and affects subsequent processing.
[0031] In a preferred embodiment, the servo motor 32 is fixedly installed on the top of the water storage tank 31, and the output end of the servo motor 32 is fixedly connected to the screw rod 321, the screw rod 321 is threadedly connected to the nut 5, the outer surface of the nut 5 is fixedly installed with a connecting rod 6, and one end of the connecting rod 6 is fixedly connected to the sealing plate 322. This device realizes automatic water addition, and it is necessary to close and open the water outlet pipe 312 in time, so a nut 5 is installed on the screw rod 321, and the rotation of the screw rod 321 will drive the nut 5 to move, and the sealing plate 322 is installed on the connecting rod 6. By moving the nut 5, the connecting rod 6 can be controlled to move up and down, thereby controlling the sealing plate 322 to move up and down, thereby realizing the closing and opening of the water outlet pipe 312, and facilitating automatic water addition to the interior of the processing tank 1.
[0032] In a preferred embodiment, the inner wall of the water tank 31 is fixedly connected to the slide rail 7, and a moving block 8 is slidably arranged on the slide rail 7. The moving block 8 is fixedly connected to the connecting rod 6 through a cross bar 9. A water inlet pipe 10 is installed on the outer surface of the water tank 31. In order to prevent the nut 5 from rotating with the screw rod 321, a slide rail 7 is installed on the inner wall of the water tank 31, and a moving block 8 is slidably installed on the slide rail 7. The moving block 8 is fixedly connected to the connecting rod 6 through a cross bar 9. The nut 5 is limited so that it cannot rotate and can only move up and down, thereby controlling the sealing plate 322 to move up and down to meet the requirements of use.
[0033] The device stirs powders and mixes multiple powders together so as to process them into re-rice. To facilitate stirring of the powders, a driving motor 11 is fixedly installed on the top of the control box 2, a driving shaft is fixedly installed on the output end of the driving motor 11, a first pulley 12 is fixedly installed on the driving shaft, a stirring shaft 13 is rotatably installed inside the processing tank 1, a second pulley 14 is fixedly installed on the bottom end of the stirring shaft 13, the first pulley 12 and the second pulley 14 are connected through a belt transmission, the first pulley 12 is controlled to rotate by the driving motor 11, the first pulley 12 drives the second pulley 14 to rotate through the belt, thereby controlling the rotation of the stirring shaft 13, and the powders are continuously stirred by the stirring shaft 13, so that the powders can be mixed together.
[0034] When adding water daily, the water will be inverted at a certain position. The water in this inverted position is sufficient, while the water in other positions is very scarce. The water is concentrated in a certain position and cannot be stirred in time, which will cause the powder in this position to clump, affecting subsequent processing. To solve this problem, the device is equipped with a sprinkler mechanism 15 inside the processing tank 31. The sprinkler mechanism 15 includes a conical cylinder 151, a water outlet 152 and a scraper 153. The conical cylinder 151 is arranged inside the processing tank 1 and is fixedly connected to the stirring shaft 13. A plurality of water outlet holes 152 are opened on the surface of the conical cylinder 151. A connecting frame 16 is fixedly installed on the outer surface of the water storage tank 1, and a scraper 153 is fixedly installed on one end of the connecting frame 16. The scraper 153 is arranged on the inner side of the conical cylinder 151 and is slidably connected to the inner side surface of the conical cylinder 151.
[0035] The servo motor 32 controls the sealing plate 322 to move. When the water starts to be released, the conical cylinder 151 and the stirring shaft 13 rotate. The water first falls into the inside of the conical cylinder 151. Since the conical cylinder 151 is in a rotating state, the water is driven to swing inside the conical cylinder 151. The device controls the rotation speed of the stirring shaft 13 to be set to 100-300r / min, so the water will not be thrown out. The water will flow obliquely downward inside the conical cylinder 151. When passing the position of the water outlet 152, it can The powder can fall from the inside of the water outlet 152, which is convenient for adding water to the powder and stirring it, and effectively prevents water from concentrating and falling at a certain position, which meets the use requirements. At the same time, when feeding, the material will be fed through the inside of the conical cylinder 151. During the feeding process, powder will adhere to the inner wall of the conical cylinder 151, so while controlling the rotation of the conical cylinder 151, the scraper 153 will be used to scrape the inner wall of the conical cylinder 151, so that the attached powder will be scraped off, and all the powder will fall into the inside of the processing tank 1 for mixing and stirring, which meets the use requirements.
[0036] Specifically, the working process or working principle of a powder mixer is: the current way to mix powder is to add powder to the inside of a mixing device, then add water to the inside of the powder, and stir the water and powder mixture through a stirring device, so as to mix multiple powders together for subsequent processing.
[0037] Although the above method can achieve the stirring of powders and mix multiple powders together, in the process of adding water, the current method of adding water is to pour the water into the stirring device at one time, which causes the powder at the upper end to be soaked in water for a long time and easily agglomerate, affecting the subsequent stirring effect. Therefore, this device is designed to solve this problem.
[0038] This device is a kind of equipment used in the production process of reprocessed rice. The method for making reprocessed rice is to grind ordinary rice into powder, and then stir it. In the stirring step, other ingredients need to be added and mixed with rice powder to form a new product, that is, rice powder of reprocessed rice. Then, these rice powders are processed into the shape of rice grains through processing equipment to produce reprocessed rice. Reprocessed rice is easy to cook and can be cooked and eaten by using a heating bag. It is more suitable for people who engage in outdoor activities.
[0039] When the powder is stirred, in order to prevent the powder from agglomerating when it encounters water, the device adopts a method of stirring first and then adding water to reduce the probability of agglomeration. When working, the mixed raw materials are added to the interior of the processing tank 1, and the raw materials are added into the interior of the processing tank 1 through the interior of the conical cylinder 151. The raw materials will enter the interior of the processing tank 1 through the water outlet 152. At the same time, the drive motor 11 is turned on, and the first pulley 12 is driven to rotate by the drive motor 11. The first pulley 12 drives the belt to rotate, which can cause the second pulley 14 to rotate and drive the stirring shaft 13 to rotate. A rotating rod is installed on the stirring shaft 13, and the powder can be stirred by the rotating rod.
[0040] When the stirring shaft 13 rotates, the conical cylinder 151 is driven to rotate. The scraper 153 slides on the inner side of the conical cylinder 151, and can scrape the raw materials that fall on the conical cylinder 151, so that it falls quickly from the inside of the water outlet 152 and falls into the inside of the processing tank 1. At the same time, under the continuous stirring of the stirring shaft 13, the powder can be evenly mixed.
[0041] At the same time, the humidity sensor 33 will detect that the powder is dry inside, and the servo motor 32 will be controlled by the PLC controller 4 to work. The servo motor 32 will drive the screw rod 321 to rotate. By controlling the movement of the nut 5, the sealing plate 322 can be moved upward, and the water outlet pipe 312 can be opened, so that water can enter the interior of the conical cylinder 151 through the water outlet pipe 312. Since the conical cylinder 151 is always in a rotating state, after the water enters the interior of the conical cylinder 151, it will not only slide downward, but also have a force to move horizontally under the action of the rotational force, which will cause the water entering the interior of the conical cylinder 151 to slide on the inner side of the conical cylinder 151 toward the bottom at a certain inclination angle. In this process, the water can directly fall into the interior of the processing tank 1 when it encounters the water outlet hole 152, so as to humidify the powder and effectively prevent the water from being concentrated in one place to prevent the powder from agglomerating.
[0042] The humidity of the upper part of the powder is continuously detected by the humidity sensor 33. After water enters the conical cylinder 151, it will first fall to the top of the powder and then slowly penetrate downward. Therefore, the humidity detection at the upper end can prevent excessive water input and affect the processing effect of the powder. When the humidity detected by the humidity sensor 33 reaches or exceeds the set value, the servo motor 32 is controlled by the PLC controller 4 to reverse, and the sealing plate 322 is closed to the water outlet pipe 312 to stop the water delivery to meet the usage.
[0043] The stirred powder can be discharged through the discharge pipe on the processing tank 1. The device is equipped with a partition inside the processing tank 1 to leave working space for the second pulley 14. The bottom end of the stirring shaft 13 will pass through the partition and be rotatably connected with the partition. In order to prevent the powder from falling from the connection between the two, a seal is installed at the connection between the stirring shaft 13 and the partition to prevent the powder from falling from the connection and causing waste of the powder.
[0044] It should be noted that the servo motor 32, humidity sensor 33, PLC controller 4 and drive motor 11 are devices or equipment that can be realized by prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
