Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating agent production technology, and in particular to a mixing and batching device for a biodegradable controlled-release urea coating agent. Background Technology
[0002] Biodegradable controlled-release urea coating agent is a functional material used to coat urea particles. It uses biodegradable polymers as the core substrate, combined with controlled-release regulators, film-forming aids, and other functional components, to form a film layer after mixing. Its core function is to form a dense and biodegradable protective film on the surface of urea particles, enabling the slow release of nutrients to match the needs of crop growth. Furthermore, the film layer can ultimately degrade into harmless substances in the soil, avoiding environmental pollution.
[0003] Currently, in the production process of biodegradable coating agents, the solid raw materials mainly consist of polylactic acid powder, diatomaceous earth, talc powder, and titanium dioxide, which are then mixed using a ribbon mixer. However, during the mixing process, due to the small particle size of titanium dioxide, agglomerates easily form between the particles. Therefore, after being fed into the ribbon mixer, it takes a long time to mix with other raw materials, thus reducing the production efficiency of the coating agent. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this utility model is to propose a biodegradable controlled-release urea coating agent mixing and batching device. Through the design of a pre-vibration dispersion mechanism, the agglomerated titanium dioxide particles are vibrated and dispersed, so that they fall evenly into the mixing box and mix with other raw materials. This solves the problem that titanium dioxide is difficult to mix with other raw materials quickly after being added, and improves the production efficiency of coating agents.
[0006] To achieve the above objectives, this utility model proposes a biodegradable controlled-release urea coating agent mixing and batching device, comprising a mixing tank, a sealing cover, a first feeding pipe, a mixing component, and a dispersing mechanism. The sealing cover is disposed on the mixing tank, the first feeding pipe is disposed on the sealing cover and communicates with the mixing tank, the mixing component is disposed inside the mixing tank and rotates axially around the mixing tank, and the dispersing mechanism includes a feeding component and two sets of driving components. The feeding component is disposed on the sealing cover and communicates with the mixing tank, and the two sets of driving components are symmetrically arranged on the feeding component.
[0007] In addition, the biodegradable controlled-release urea coating agent mixing and dispensing device proposed above according to this utility model may also have the following additional technical features: Specifically, the mixing assembly includes a screw ribbon and a driving component, wherein the screw ribbon is rotatably disposed inside the mixing chamber, the driving component is disposed on the mixing chamber, and its output shaft is fixedly connected to the screw ribbon.
[0008] Specifically, the feeding assembly includes a support tube, a dispersion box, two optical axes, four limiting sleeves, and a titanium dioxide input tube. The four limiting sleeves are symmetrically arranged on the dispersion box, the two optical axes are symmetrically arranged inside the support tube, the limiting sleeves are slidably arranged on the optical axes, and the titanium dioxide input tube is arranged on the support tube and corresponds to the position of the dispersion box.
[0009] Specifically, each drive assembly includes two fixed seats, a vibrator, a mounting seat, a guide shaft, two elastic elements, and a guide seat. The two fixed seats are symmetrically arranged at both ends of the guide shaft. The vibrator is mounted on the guide shaft via the mounting seat. The guide shaft is slidably disposed within the guide seat. The two elastic elements are symmetrically sleeved on the guide shaft, and the two ends of the elastic elements abut against the fixed seats and the guide seats, respectively.
[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: By setting up a dispersion mechanism, before titanium dioxide is put into the mixing box, the dispersion box is driven by the vibrator to generate reciprocating linear motion, which strongly vibrates the titanium dioxide particles in the dispersion box, thereby effectively breaking up the titanium dioxide agglomerates. The broken titanium dioxide falls evenly into the mixing box through the dispersion holes and is initially mixed with other raw materials, thus solving the problem that titanium dioxide is difficult to quickly disperse and mix with other raw materials after being put into the box, and improving the production efficiency of coating agents.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0015] The following description, in conjunction with the accompanying drawings, describes the biodegradable controlled-release urea coating agent mixing and batching device according to an embodiment of the present invention.
[0016] like Figures 1-5 As shown in the figure, a biodegradable controlled-release urea coating agent mixing and batching device according to an embodiment of the present invention includes a mixing tank 1, a sealing cover 2, a first feeding pipe 3, a mixing component 4, and a dispersing mechanism. The sealing cover 2 is disposed on the mixing tank 1, and the first feeding pipe 3 is disposed on the sealing cover 2 and communicates with the mixing tank 1.
[0017] It should be noted that the sealing cover 2 is hinged to the mixing box 1, and the contact surfaces of the sealing cover 2 and the mixing box 1 are provided with sealing gaskets (not shown in the figure) to ensure the sealing effect during the mixing process. The bottom of the mixing box 1 is provided with a discharge pipe (not shown in the figure). By opening the discharge pipe, the mixed ingredients can be discharged.
[0018] The first feeding pipe 3 is used to feed polylactic acid powder, diatomaceous earth and talc powder and other coating agent raw materials. The top of the first feeding pipe 3 is provided with a cap (not shown in the figure) to prevent external impurities from entering the mixing box 1 during the mixing process, and to ensure the sealing of the mixing process.
[0019] The mixing component 4 is disposed inside the mixing chamber 1 and rotates axially around the mixing chamber 1. The dispersing mechanism includes a feeding component 5 and two sets of driving components 6. The feeding component 5 is disposed on the sealing cover 2 and communicates with the mixing chamber 1. The two sets of driving components 6 are symmetrically disposed on the feeding component 5.
[0020] It should be noted that the dispersion mechanism is used to pre-disperse titanium dioxide to solve the problem that titanium dioxide is difficult to mix quickly with other raw materials after being put into the ribbon mixer.
[0021] In one embodiment of this utility model, such as Figure 2 As shown, the mixing assembly 4 includes a screw ribbon 41 and a drive member 42. The screw ribbon 41 is rotatably disposed inside the mixing chamber 1, and the drive member 42 is disposed on the mixing chamber 1, with its output shaft fixedly connected to the screw ribbon 41.
[0022] It should be noted that the shaft of the screw ribbon 41 is rotatably mounted in the mixing box 1 through bearings. The screw ribbon 41 has a double helix structure, and its outer edge is clearance-fitted with the inner wall of the mixing box 1 to ensure that the raw materials in the mixing box 1 can be fully agitated during rotation, so that the various raw materials can be mixed evenly. The drive component 42 is a geared motor, which is connected to the shaft of the screw ribbon 41 through a coupling.
[0023] Understandably, after the drive unit 42 is started, it can drive the screw ribbon 41 to rotate around the axis of the mixing box 1, thereby stirring and mixing the coating agent raw materials in the mixing box 1, and the raw materials are mixed more evenly.
[0024] In one embodiment of this utility model, such as Figures 3-4 As shown, the feeding assembly 5 includes a support tube 51, a dispersion box 52, two optical axes 53, four limiting sleeves 54, and a titanium dioxide inlet tube 55. The four limiting sleeves 54 are symmetrically arranged on the dispersion box 52, the two optical axes 53 are symmetrically arranged inside the support tube 51, the limiting sleeves 54 are slidably arranged on the optical axes 53, and the titanium dioxide inlet tube 55 is arranged on the support tube 51 and corresponds to the position of the dispersion box 52.
[0025] It should be noted that the support tube 51 is installed on the sealing cover 2 and is connected to the mixing box 1. The limiting sleeve 54 is fixedly installed on the dispersion box 52. The two ends of the optical axis 53 are symmetrically fixed inside the support tube 51. The limiting sleeve 54 slides on the optical axis 53 through the linear bearing installed inside it, so that the dispersion box 52 can slide along the optical axis 53.
[0026] The lower surface of the dispersion box 52 is uniformly provided with multiple dispersion holes for discharging the dispersed titanium dioxide into the mixing box 1, so as to prevent the titanium dioxide from forming agglomerates again in the mixing box 1 after being added. The top of the titanium dioxide inlet pipe 55 is provided with a cap (not shown in the figure) to ensure the sealing during the mixing process.
[0027] In one embodiment of this utility model, such as Figure 5 As shown, each drive assembly 6 includes two fixed seats 61, a vibrator 62, a mounting seat 63, a guide shaft 64, two elastic elements 65, and a guide seat 66. The two fixed seats 61 are symmetrically arranged at both ends of the guide shaft 64. The vibrator 62 is mounted on the guide shaft 64 through the mounting seat 63. The guide shaft 64 is slidably disposed within the guide seat 66. The two elastic elements 65 are symmetrically sleeved on the guide shaft 64, and the two ends of the elastic elements 65 abut against the fixed seats 61 and the guide seats 66, respectively.
[0028] It should be noted that the two sets of drive components 6 are symmetrically located on both sides of the dispersion box 52. The guide shaft 64 is fixedly installed on the outer wall of the dispersion box 52 through the fixing seat 61, and the guide seat 66 is fixedly installed inside the support tube 51. The guide seat 66 slides on the guide shaft 64 through the linear bearing inside it.
[0029] The elastic element 65 is a spring, which is sleeved on the guide shaft 64 to provide elastic restoring force for the reciprocating motion of the dispersion box 52.
[0030] Understandably, after the vibrator 62 is started, the guide shaft 64 is driven to slide in the guide seat 66 through the mounting base 63. At the same time, under the elastic action of the elastic element 65, the dispersion box 52, through the cooperation of the limiting sleeve 54 and the optical axis 53, generates reciprocating linear motion along the optical axis 53, thereby causing the titanium dioxide particles in the dispersion box 52 to be subjected to strong vibration, thus effectively breaking up the agglomerates and allowing them to fall into the mixing box 1 in a relatively dispersed state after passing through the dispersion hole, where they are initially mixed with raw materials such as polylactic acid powder, diatomaceous earth, and talc.
[0031] In practical applications, when mixing and preparing biodegradable controlled-release urea coating agents, polylactic acid powder, diatomaceous earth, talc powder, and other raw materials are first fed into the mixing box 1 through the first feeding pipe 3. At the same time, the drive unit 42 is started, which drives the screw ribbon 41 to rotate. The screw ribbon 41 stirs the raw materials in the mixing box 1 for mixing.
[0032] Next, titanium dioxide is fed into the dispersion box 52 through the titanium dioxide feeding pipe 55, and at the same time the vibrator 62 is started, so that the dispersion box 52 reciprocates linearly along the axial direction of the optical axis 53. The titanium dioxide particles in the dispersion box 52 are subjected to strong vibration, and the agglomerates are effectively dispersed. Then, in a relatively dispersed state, they fall into the mixing box 1 through multiple dispersion holes on the lower surface of the dispersion box 52 and are mixed with the previously fed raw materials, thereby realizing the mixing and formulation of the biodegradable controlled-release urea coating agent.
[0033] During this process, as the dispersion box 52 continues to vibrate, the titanium dioxide particles are not only effectively dispersed, but also evenly distributed in the internal space of the mixing box 1 due to the vibration, thereby effectively preventing the titanium dioxide particles from agglomerating again.
[0034] In summary, the biodegradable controlled-release urea coating agent mixing and batching device of this utility model, by setting a dispersion mechanism, uses the driving action of the vibrator to make the dispersion box reciprocate linear motion before titanium dioxide is added to the mixing box, which strongly vibrates the titanium dioxide particles in the dispersion box, thereby effectively breaking up the titanium dioxide agglomerates. The broken titanium dioxide falls evenly into the mixing box through the dispersion holes and is initially mixed with other raw materials, thus solving the problem that titanium dioxide is difficult to quickly disperse and mix with other raw materials after being added, and improving the production efficiency of the coating agent.
