Description

TECHNICAL FIELD

[0001] The utility model relates to the field of radionuclide adsorption material production technology, specifically to a kind of radionuclide adsorption material production is dried with dryer. BACKGROUND

[0002] Radionuclide adsorption material refers to those solid substances that can adsorb radionuclides from solution. These materials usually have a large specific surface area and a special surface structure, which allows them to effectively bind to radionuclides. The radionuclide adsorption material dryer is a device specifically designed for drying radionuclide adsorption materials. This dryer needs to meet specific process requirements to ensure that the adsorption material maintains its adsorption properties and structural stability during the drying process.

[0003] The existing radionuclide adsorption material dryer, one is through the screw conveyor to place the separated radionuclide adsorption material in the designated container, and then personnel place the container in the drying chamber, the heat source system provides heat for the drying chamber, transfers heat to the adsorption material, evaporates the internal moisture, and then completes the drying work. When the drying is completed, personnel take out the container containing the dried radionuclide adsorption material. The other is transported to the drying chamber by means of an electric conveyor belt, the heat source system provides heat for the drying chamber, transfers heat to the adsorption material, evaporates the internal moisture, and then completes the drying work. This type of radionuclide adsorption material dryer has some problems. The former manually operates to store and take out the radionuclide adsorption material container, which is tedious and slow, and the personnel's work burden is large. The latter achieves automatic feeding, drying and discharging in a flow line, but is limited by the contact between the radionuclide adsorption material and the belt body of the electric conveyor belt, resulting in drying dead angles. To some extent, both cannot achieve the compatibility of continuity and thoroughness of drying work. SUMMARY

[0004] The utility model solves the technical problem of overcoming the existing defects and provides a radionuclide adsorption material dryer. The radionuclide adsorption material achieves good compatibility in continuity and thoroughness of drying work, effectively solving the problems in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a radionuclide adsorption material dryer, including drying bin, the middle part of the outer surface of drying bin is provided with heating bin, still including feeding mechanism.

[0006] The feeding mechanism includes a rotating shaft, a semi-circular arc plate, and scrapers. The rotating shaft is rotatably connected to the top wall of the drying chamber, and the outer surface of the rotating shaft is fixedly connected with staggered scrapers. The semi-circular arc plates are vertically staggered and fixedly connected to the inner wall of the drying chamber. The lower ends of the scrapers are fitted with the upper surfaces of the radially adjacent semi-circular arc plates. The interior of each semi-circular arc plate is provided with uniformly distributed through holes, which can disperse the radionuclide adsorbent material and prevent it from clumping. The radionuclide adsorbent material is tumbled to a certain extent during the flow process, and all surfaces can exchange heat and dry. Moreover, there is no need for personnel to take out and put in the containers storing the radionuclide adsorbent material, which effectively simplifies the drying process of the radionuclide adsorbent material, reduces the workload of the staff, and achieves good compatibility between the continuity and thoroughness of the drying work.

[0007] Furthermore, the feeding mechanism also includes support rods and dispersing needles. The support rods are symmetrically and fixedly connected to the middle of the rotating shaft. The lower ends of the support rods are all fixedly connected to evenly distributed dispersing needles. The lower ends of the dispersing needles are all fitted with the upper surfaces of the radially adjacent semi-circular arc plates to achieve the dispersion of radioactive nuclide adsorption material on the upper surface of the semi-circular arc plates.

[0008] Furthermore, a control switch group is provided on the left side of the drying chamber. The input terminal of the control switch group is electrically connected to an external power source to control various electrical appliances.

[0009] Furthermore, the feeding mechanism also includes a motor, which is located at the upper end of the drying chamber. The lower end of the output shaft of the motor is fixedly connected to the upper end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the control switch group, providing driving force for the dispersion and active feeding of the radioactive nuclide adsorption material.

[0010] Furthermore, the bottom wall of the heating chamber is equipped with evenly distributed heaters, the input ends of which are electrically connected to the output ends of the control switch group to provide heat for drying the radioactive nuclide adsorption material.

[0011] Furthermore, a feed hopper is provided at the left end of the upper surface of the drying chamber, and a discharge chamber is provided at the lower end of the drying chamber. A discharge port is provided at the left end of the lower surface of the discharge chamber. A rotating column is rotatably connected inside the discharge chamber, and a spiral blade is fixedly connected to the outer surface of the rotating column. The spiral blade is installed in conjunction with the inner wall of the discharge chamber to realize the spiral discharge of the radioactive nuclide adsorption material.

[0012] Furthermore, a second motor is provided at the right end of the discharge hopper. The left end of the output shaft of the second motor is fixedly connected to the right end of the rotating column, and the input end of the second motor is electrically connected to the output end of the control switch group to provide driving force for the spiral discharge of the radioactive nuclide adsorption material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This dryer for producing radioactive nuclide adsorption materials has the following advantages:

[0014] The staggered semi-circular arc plates effectively increase the residence time of radionuclide adsorbent materials inside the drying chamber. Simultaneously, the rotating scraper scrapes and feeds the materials onto the semi-circular arc plates, while the rotating dispersing needles disperse the radionuclide adsorbent materials on the upper surface of the plates, preventing clumping. The materials tumble during the flow, ensuring heat exchange and drying on all surfaces. Furthermore, no personnel are required to handle the containers storing the radionuclide adsorbent materials, effectively simplifying the drying process, reducing the workload of staff, and achieving a good balance between continuity and thoroughness in the drying process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1-3 This embodiment provides a technical solution: a dryer for producing radioactive nuclide adsorption materials, including a drying chamber 1, a heating chamber 3 arranged in the middle of the outer surface of the drying chamber 1, a control switch group 10 arranged on the left side of the drying chamber 1, the input end of the control switch group 10 being electrically connected to an external power supply, and also including a feeding mechanism 2.

[0021] Feeding mechanism 2 includes a rotating shaft 21, a semi-circular arc plate 22, and scrapers 23. The rotating shaft 21 is rotatably connected to the top wall of the drying chamber 1. The outer surface of the rotating shaft 21 is fixedly connected with staggered scrapers 23. The semi-circular arc plates 22 are vertically staggered and fixedly connected to the inner wall of the drying chamber 1. The lower ends of the scrapers 23 are fitted with the upper surfaces of radially adjacent semi-circular arc plates 22. The interiors of the semi-circular arc plates 22 are provided with evenly distributed through holes. The feeding mechanism 2 also includes support rods 24 and... Dispersing needles 25 and support rods 24 are symmetrically fixedly connected to the middle of the rotating shaft 21. Dispersing needles 25 are evenly distributed and fixedly connected to the lower ends of the support rods 24. The lower ends of the dispersing needles 25 are fitted to the upper surfaces of the radially adjacent semi-circular arc plates 22. The feeding mechanism 2 also includes a motor 26, which is located at the upper end of the drying chamber 1. The lower end of the output shaft of the motor 26 is fixedly connected to the upper end of the rotating shaft 21. The input end of the motor 26 is connected to the output end of the control switch group 10. The connection is achieved by controlling the switch group 10 to make the motor 26 run. The output shaft of the motor 26 rotates, which drives the rotating shaft 21 to rotate. The rotating shaft 21 rotates, which drives the scraper 23 to contact. When the scraper 23 reaches the upper end of the radially adjacent semi-circular arc plate 22, the scraper 23 is in contact with the upper surface of the corresponding semi-circular arc plate 22, and scrapes the radionuclide adsorbent material on the upper surface of the semi-circular arc plate 22 to the upper surface of the staggered lower semi-circular arc plate 22, so that the radionuclide adsorbent material moves down layer by layer inside the drying chamber 1. At the same time, the rotating shaft 21 rotates, which drives the symmetrically distributed support rods 24 to rotate. The rotation of the support rods 24 drives the radially adjacent dispersing needles 25 to rotate around the central axis of the rotating shaft 21. When the dispersing needles 25 reach the upper end of the radially adjacent semi-circular arc plate 22, the dispersing needles 25 are in contact with the upper surface of the corresponding semi-circular arc plate 22 and slide, thereby dispersing the radionuclide adsorbent material on the upper surface of the semi-circular arc plate 22 and preventing the radionuclide adsorbent material from clumping.

[0022] Wherein: the bottom wall of the heating chamber 3 is provided with evenly distributed heaters 4, the input end of each heater 4 is electrically connected to the output end of the control switch group 10, and the heater 4 is operated by the control switch group 10, and the heater 4 heats the drying chamber 1.

[0023] The drying chamber 1 has a feed hopper 9 on the left side of its upper surface, through which radioactive nuclide adsorption material is injected into the drying chamber 1. A discharge chamber 5 is located at the lower end of the drying chamber 1, with a discharge port on the left side of its lower surface. A rotating column 6 is rotatably connected inside the discharge chamber 5, and a spiral blade 7 is fixedly connected to the outer surface of the rotating column 6. The spiral blade 7 is fitted into the inner wall of the discharge chamber 5. A second motor 8 is located at the right end of the discharge chamber 5. The left end of the output shaft of the second motor 8 is fixedly connected to the right end of the rotating column 6. The input end of the second motor 8 is electrically connected to the output end of the control switch group 10. The control switch group 10 enables the second motor 8 to operate. The rotation of the output shaft of the second motor 8 drives the rotating column 6 to rotate, which in turn drives the spiral blade 7 to rotate. The shearing force generated by the spiral blade 7 against the inner wall of the discharge chamber 5 achieves the spiral conveying of the dried radioactive nuclide adsorption material. Finally, the radioactive nuclide adsorption material is removed through the discharge port.

[0024] The working principle of the dryer for producing radionuclide adsorption materials provided by this utility model is as follows: During operation, the operator first places the drying chamber 1, heating chamber 3, and other mechanisms stably in a horizontal working area. After stable placement, the operator activates the heater 4 via the control switch group 10. The heater 4 heats the drying chamber 1. When the air inside the drying chamber 1 reaches a certain level, the operator injects radionuclide adsorption material into the drying chamber 1 through the feed hopper 9. Simultaneously, the operator activates the motor 26 via the control switch group 10. The output shaft of the motor 26 rotates, driving the rotating shaft 21 to rotate. The rotating shaft 21 then drives the scraper 23 to contact the upper end of the radially adjacent semi-circular arc plate 22. When the scraper 23 reaches the upper end of the radially adjacent semi-circular arc plate 22, the scraper 23 adheres to the upper surface of the corresponding semi-circular arc plate 22, scraping the radionuclide adsorption material on the upper surface of the semi-circular arc plate 22 to the upper surface of the staggered lower semi-circular arc plate 22. The surface allows the radionuclide adsorbent material to move down layer by layer inside the drying chamber 1. At the same time, the rotation of the rotating shaft 21 drives the symmetrically distributed support rods 24 to rotate. The rotation of the support rods 24 drives the radially adjacent dispersing needles 25 to rotate around the central axis of the rotating shaft 21. When the dispersing needles 25 reach the upper end of the radially adjacent semi-circular arc plates 22, the dispersing needles 25 slide against the upper surface of the corresponding semi-circular arc plates 22, thereby dispersing the radionuclide adsorbent material on the upper surface of the semi-circular arc plates 22 and preventing the radionuclide adsorbent material from clumping. After the radionuclide adsorbent material is dried, the personnel control the switch group 10 to start the motor 8. The output shaft of the motor 8 rotates, which drives the rotating column 6 to rotate. The rotating column 6 rotates, which drives the spiral blade 7 to rotate. The shearing force generated by the spiral blade 7 and the inner wall of the discharge chamber 5 realizes the spiral conveying of the dried radionuclide adsorbent material. Finally, the radionuclide adsorbent material is removed through the discharge port.

[0025] It is worth noting that the motor 26 disclosed in the above embodiments can be a YE3-80M1-2 low-speed motor, and the control switch group 10 is provided with control buttons that correspond one-to-one with the motor 26, heater 4 and motor 8 and control their switching.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
