Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of explosion-proof plate processing, and more specifically, to an explosion-proof plate raw material mixing device. Background Technology

[0002] In the production of explosion-proof panels, raw material mixing is a crucial process to ensure product performance. Its uniformity and production efficiency directly affect the core indicators of explosion-proof panels, such as impact resistance and flame retardancy. However, traditional raw material mixing devices for explosion-proof panels generally suffer from simple mixing structures and limited functionality, making it difficult to meet the demands of modern production for efficient mixing and clean manufacturing.

[0003] Existing mixing devices mostly employ a single-blade mixing structure, with a fixed blade speed and trajectory, which cannot adapt to the mixing requirements of various raw materials. For example, explosion-proof plate materials typically contain multiple components such as metal particles, flame retardants, and binders. When traditional mixing blades rotate, denser metal particles tend to sink to the bottom, while lighter flame retardants float to the top, resulting in uneven mixing. This necessitates extended mixing times to achieve the required mixing, leading to low production efficiency. Furthermore, when handling high-viscosity raw materials, the simple mixing structure easily causes material to adhere to the blades or the mixing tank walls, further reducing mixing efficiency and even requiring frequent shutdowns for cleaning, increasing labor costs.

[0004] Furthermore, the lack of wastewater treatment design in traditional equipment leads to cumbersome cleaning procedures. After mixing, the residual raw materials inside the equipment need to be rinsed with large amounts of clean water. However, existing equipment lacks a dedicated wastewater separation and discharge system, resulting in the direct discharge of wastewater mixed with residual raw materials. This not only wastes water resources but may also cause pipe blockages. For example, some companies have to manually scoop out wastewater and residue together when cleaning the mixing tank, which is time-consuming, labor-intensive, and prone to environmental pollution, failing to meet environmental protection production requirements.

[0005] With the expanding applications of explosion-proof panels, market demands for product quality and production efficiency are increasing, highlighting the shortcomings of traditional mixing devices. Developing a new type of explosion-proof panel raw material mixing device with a highly efficient mixing structure, adaptable to multi-raw material mixing needs, and convenient wastewater separation and discharge capabilities is urgently needed. Optimizing the mixing structure to improve mixing uniformity and efficiency, and designing a dedicated wastewater treatment system to achieve clean production, are of great significance for improving the quality of explosion-proof panel products, reducing production costs, and promoting the green development of the industry. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide an explosion-proof plate raw material mixing device, which solves the technical problem that existing mixing devices mostly adopt a single blade mixing structure, and the rotation speed and trajectory of the mixing blade are fixed, which cannot adapt to the mixing requirements of multiple raw materials.

[0007] According to one aspect, at least one embodiment of the present disclosure provides a mixing device for explosion-proof plate raw materials, comprising:

[0008] The tank body, the first annular frame, and the second annular frame are both disposed on the top of the tank body;

[0009] The discharge pipe is located at the bottom of the tank, and the discharge separation component is located on the discharge pipe and outside the tank.

[0010] A stirring motor and a stirring assembly are provided, wherein the stirring motor is disposed on the top of the tank body and the stirring assembly is disposed on the first annular frame and the second annular frame;

[0011] The stirring assembly includes an inner frame, which is fixed inside the second annular frame. The second annular frame is fitted onto the top of the tank and slidably connected to the first annular frame. A top frame is provided outside the first annular frame, and the stirring motor is mounted on the top frame. A central stirring frame is provided at the output end of the stirring motor.

[0012] As a further technical solution, a sealing plate is provided at the bottom of the inner frame, and a feeding port is opened on the surface of the sealing plate. Several secondary shafts are rotatably connected between the sealing plate and the inner frame, and stirring blades are provided on the secondary shafts.

[0013] As a further technical solution, a main gear is provided on the central stirring frame, and secondary gears are provided on the secondary shaft. The secondary gears mesh with the main gears, and a sealing seat is rotatably connected to the lower end of the central stirring frame.

[0014] As a further technical solution, the outer wall of the tank is provided with a plurality of telescopic cylinders, the output end of the telescopic cylinders is connected to the first annular frame, a control motor is provided at one end of the top of the top frame, a drive gear is provided at the output end of the control motor, and an external gear is provided on the outer wall of the second annular frame, the external gear meshing with the drive gear.

[0015] As a further technical solution, the separation and discharge assembly includes a second cylinder, which is fixed at the bottom of the tank. The output end of the second cylinder is located inside the discharge pipe, and a sealing plate is provided at the output end of the second cylinder. A waste discharge pipe is provided at the bottom of the discharge pipe.

[0017] As a further technical solution, the stirring blades have a spiral structure.

[0018] As a further technical solution, the cross-section at the connection between the first annular frame and the top of the tank has a stepped structure.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effects of the stirring assembly in this disclosure are that the gear transmission structure of the central stirring frame and the secondary shaft realizes the main and auxiliary coordinated stirring. The spiral stirring blades rotate with the second ring frame while rotating on their own axis, forming a three-dimensional stirring trajectory, which effectively avoids the problem of metal particles sinking to the bottom and light raw materials floating, and improves the mixing uniformity of raw materials of different densities. The design of adjusting the stirring height with a telescopic cylinder allows the device to adapt to the stirring of raw materials of different volumes, avoids the phenomenon of high viscosity raw materials adhering to the tank wall, reduces the number of shutdowns for cleaning, and the dual stirring motion significantly shortens the stirring time and improves production efficiency compared with the traditional single blade structure. It can also adapt to the mixing needs of various raw materials and ensure the stirring quality of the explosion-proof plate raw materials.

[0021] 2. The beneficial effect of the discharge component in this disclosure is that the design of the second cylinder and the sealing plate enables precise separation of materials and wastewater. After mixing, the discharge or wastewater discharge mode can be quickly switched by controlling the extension and retraction of the cylinder, avoiding the problem of mixed discharge of wastewater and materials in traditional devices. The independent setting of the wastewater discharge pipe facilitates centralized wastewater treatment, reduces water waste and the risk of pipe blockage, and avoids the tedious operation of manually cleaning wastewater, reducing labor intensity. This component ensures clean production, meets environmental protection requirements, and effectively prevents impurities from mixing in when discharging materials, ensuring the purity of the explosion-proof plate raw materials and improving product quality stability.

[0034] like Figures 1-4 As shown, it illustrates a raw material mixing device for explosion-proof plates according to an embodiment of the present disclosure, comprising:

[0035] Tank 1, first annular frame 2 and second annular frame 3, the first annular frame 2 and the second annular frame 3 are both disposed on the top of the tank 1;

[0036] The discharge pipe 4 and the distinguishing discharge component 7 are provided. The discharge pipe 4 is located at the bottom of the tank body 1, and the distinguishing discharge component 7 is located outside the discharge pipe 4 and the tank body 1.

[0037] A stirring motor 5 and a stirring assembly 6 are provided. The stirring motor 5 is located on the top of the tank body 1, and the stirring assembly 6 is located on the first annular frame 2 and the second annular frame 3.

[0038] The stirring assembly 6 includes an inner frame 6-1, which is fixed inside the second annular frame 3. The second annular frame 3 is fitted onto the top of the tank body 1 and slidably connected to the first annular frame 2. A top frame 6-2 is provided outside the first annular frame 2. The stirring motor 5 is mounted on the top frame 6-2, and a central stirring frame 6-3 is provided at the output end of the stirring motor 5. A sealing plate 6-4 is provided at the bottom of the inner frame 6-1, and a feeding port 6-5 is opened on the surface of the sealing plate 6-4. Several secondary shafts 6-6 are rotatably connected between the sealing plate 6-4 and the inner frame 6-1, and stirring blades 6-7 are provided on the secondary shafts 6-6. A main gear 6-8 is provided on the central stirring frame 6-3, and a secondary gear 6-9 is provided on each of the secondary shafts 6-6. The secondary gears 6-9 mesh with the main gear 6-8. A sealing seat 6-10 is rotatably connected to the lower end of the central stirring frame 6-3. Several telescopic cylinders 6-11 are provided on the outer wall of the tank body 1. The output end of the telescopic cylinders 6-11 is connected to the first annular frame 2. A control motor 6-12 is provided at one end of the top of the top frame 6-2. A drive gear 6-13 is provided at the output end of the control motor 6-12. An external gear 6-14 is provided on the outer wall of the second annular frame 3. The external gear 6-14 meshes with the drive gear 6-13.

[0039] In some examples, to achieve efficient mixing in the mixing of explosion-proof plate raw materials, a mixing assembly 6 is designed. This assembly uses an inner frame 6-1 fixed inside a second annular frame 3 as a support structure. The second annular frame 3 is fitted onto the top of the tank 1 and can slide on the first annular frame 2. The drive gear 6-13 at the output end of the control motor 6-12 on the top frame 6-2 meshes with the outer gear 6-14 on the outer wall of the second annular frame 3, driving the second annular frame 3 to rotate around the center of the tank 1, causing the inner frame 6-1 and the internal mixing components to form a circular motion. The mixing motor 5 is mounted on the top frame 6-2. The lower end of the central stirring frame 6-3 at the output end is rotatably connected to the sealing seat 6-10 to block the outlet. The main gear 6-8 on the central stirring frame 6-3 meshes with the secondary gear 6-9 on the secondary shaft 6-6. When the central stirring frame 6-3 rotates, it drives the secondary shaft 6-6 and the stirring blades 6-7 to rotate synchronously, forming a multi-stage transmission structure of main stirring and secondary stirring. The surface of the sealing plate 6-4 at the bottom of the inner frame 6-1 has a feeding port 6-5 for adding raw materials. The secondary shaft 6-6 rotating between the sealing plate 6-4 and the inner frame 6-1 can stir the raw materials near the feeding port 6-5.

[0040] The output end of the telescopic cylinder 6-11 on the outer wall of the tank 1 is connected to the first annular frame 2, which can adjust the height of the second annular frame 3 and lift the sealing seat 6-10 at the lower end of the central mixing frame 6-3 to open the discharge.

[0041] Through the coordinated operation of the rotation of the second ring frame 3, the gear transmission between the central stirring frame 6-3 and the secondary shaft 6-6, and the height adjustment of the telescopic cylinder 6-11, the stirring assembly 6 achieves efficient and all-round stirring of the explosion-proof plate raw materials, ensuring uniform mixing of the raw materials.

[0042] like Figures 1-4 As shown in the figure, the present embodiment proposes that the distinguishing discharge component 7 includes a second cylinder 7-1, the second cylinder 7-1 is fixed at the bottom of the tank body 1, the output end of the second cylinder 7-1 is located in the discharge pipe 4, the output end of the second cylinder 7-1 is provided with a sealing plate 7-2, and the bottom of the discharge pipe 4 is provided with a waste discharge pipe 7-3.

[0043] In some examples, after the raw materials for the explosion-proof plate are mixed, a separate discharge component 7 is designed to achieve the separate discharge of materials and wastewater. This component uses a second cylinder 7-1 fixed at the bottom of the tank 1 as the control core. The sealing plate 7-2 at its output end is located in the discharge pipe 4. When it is necessary to discharge wastewater or impurities, the second cylinder 7-1 retracts and drives the sealing plate 7-2 to move horizontally, opening the passage between the discharge pipe 4 and the waste discharge pipe 7-3. Wastewater or impurities are discharged separately through the waste discharge pipe 7-3. When it is necessary to discharge the mixed materials, the second cylinder 7-1 extends and pushes the sealing plate 7-2 to the right, closing the waste discharge pipe 7-3. The materials are discharged normally through the discharge pipe 4.

[0044] The position of the sealing plate 7-2 is controlled by the extension and retraction of the second cylinder 7-1, which accurately distinguishes the discharge paths of materials and wastewater, prevents impurities from mixing into the finished product, ensures product quality, and facilitates centralized treatment of wastewater.

[0045] For example, such as Figure 4 As shown, the feeding port 6-5 has a funnel-shaped opening structure.

[0046] In some examples, the funnel-shaped opening structure makes it easier to feed materials.

[0047] For example, such as Figure 3 As shown, the stirring blades 6-7 have a spiral structure.

[0048] In some examples, the spiral structure, combined with the rotation of the second ring frame 3, can enhance the mixing efficiency, allowing the internal materials to quickly impact each other and create a mixing effect.

[0049] For example, such as Figure 3 As shown, the cross-section of the connection between the first annular frame 2 and the top of the tank body 1 has a stepped structure.

[0050] In some examples, the stepped structure can increase the sealing of the connection between the first annular frame 2 and the tank body 1.

[0051] In practical use: Solid raw materials such as cement, quartz sand, fly ash, gypsum, SiO2 powder, and Al2O3 powder are fed into tank 1 through feeding port 6-5 using the explosion-proof plate. The stirring motor 5 starts, driving the central stirring frame 6-3 to rotate. The main gear 6-8 drives the secondary shaft 6-6 and the spiral stirring blades 6-7 to rotate via the secondary gear 6-9. Simultaneously, the motor 6-12 drives the drive gear 6-13 to mesh with the external gear 6-14, causing the second annular frame 3 to drive the inner frame 6-1 to rotate along the first annular frame 2, forming... The dual stirring motion of the central stirring frame 6-3 and the stirring blades 6-7, and the telescopic cylinder 6-11 can adjust the lifting and lowering of the first annular frame 2 and the second annular frame 3 according to the height of the raw materials to ensure that the stirring covers the entire tank. After the stirring is completed, if it is necessary to discharge the material, the telescopic cylinder 6-11 controls the first annular frame 2 to rise, the sealing seat 6-10 to open, and the material is discharged through the discharge pipe 4. During flushing, the second cylinder 7-1 extends to push the sealing plate 7-2 to move, opening the waste discharge pipe 7-3, and the wastewater can be discharged separately through the waste discharge pipe 7-3.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
