Description

Technical Field

[0001] This invention belongs to the field of multi-component proppant production technology, and more specifically, relates to a multi-component proppant raw material quantitative conveying and mixing machine. Background Technology

[0002] In the production of multi-component proppant, raw material mixing is a core pre-process. It can fully homogenize powders of different components such as bauxite, kaolin, and functional additives, avoiding component segregation due to differences in particle size and density. This ensures that the material composition is uniform and stable in subsequent granulation and sintering processes. This not only ensures that the key performance indicators such as strength, density, and sphericity of each ceramic particle are consistent and controllable, but also reduces the performance fluctuation between batches of products, ultimately ensuring that the fracture support effect and conductivity of the proppant in fracturing operations are consistently up to standard.

[0003] The raw material mixers currently in use still have the following problems: 1. They do not have a quantitative conveying function, which cannot guarantee that the raw materials to be mixed are continuously conveyed in a quantitative manner according to the proportion, affecting the mixing accuracy of multi-component proppant raw materials; 2. The mixing of raw materials and the discharge of the mixed materials cannot be carried out simultaneously, which increases the manufacturing cost of the equipment; 3. They usually lack auxiliary stabilizing structures, which makes the mixer prone to shaking when mixing raw materials. Summary of the Invention

[0004] This invention relates to a multi-component proppant raw material quantitative conveying mixer, which includes a raw material separation unit, a quantitative conveying unit, a raw material mixing unit, a raw material premixing unit, and a multi-purpose stabilizing unit. A row of quantitative conveying rods drives a row of spiral blades a to rotate, so that the raw material in the raw material storage tank can be quantitatively conveyed to the raw material mixing tube. It ensures that the premixed raw material can move automatically from left to right, so that a row of raw material mixing racks can automatically mix the premixed raw material. When the stabilizing support slides to the left, the left ends of the two stabilizing limit rods move to the top of the two rows of mounting bolts on the raw material storage tank, preventing the two rows of mounting bolts on the raw material storage tank from loosening. It solves the problems of not being able to ensure that the raw material to be mixed is continuously and quantitatively conveyed according to the ratio, the inability to simultaneously carry out raw material mixing and discharge of the mixed material, and the easy shaking of the mixer during raw material mixing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, it is convenient for staff to adjust the angle of the raw material partition plate according to the ratio between raw materials, which is beneficial to improving the storage effect of the raw material storage box; the setting of two rows of clamping threaded nails plays a clamping and positioning role on one row of raw material partition plates after the angle is rotated, so that one row of raw material partition plates is in a stable state after rotation.

[0029] The specific functions of the raw material mixing unit 300 and the raw material premixing unit 400 are as follows: Since the servo motor b302 is fixedly installed on the left side of the raw material mixing pipe 301, and the raw material mixing shaft 303 is fixedly installed on the output shaft of the servo motor b302, and the raw material premixing rack 402 is slidably installed outside the raw material mixing shaft 303, when the control box 600 controls the servo motor b302 to work, the raw material mixing shaft 303 drives the raw material premixing rack 402 to rotate, which plays a radial premixing role on the different raw materials discharged from a row of quantitative conveying pipes 102; Since the spiral blade b304 is fixedly installed outside the raw material mixing shaft 303, and a row of raw material mixing racks 305 is fixedly installed outside the raw material mixing shaft 303, and the row of raw material mixing racks 305 is located on the right side of the spiral blade b304, it ensures that the premixed raw materials can move automatically from left to right, so that the row of raw material mixing racks 305 automatically mixes the premixed raw materials; Furthermore, since the four rows of L-shaped premix plates 403 are fixedly installed on the raw material premixing rack 402, and the four arc-shaped extrusion plates 404 are fixedly installed on the left side of the inner wall of the raw material mixing pipe 301, when the raw material mixing shaft 303 drives the raw material premixing rack 402 to rotate, the four arc-shaped extrusion plates 404 can push the raw material premixing rack 402 to slide to the right a certain distance, which plays an axial premixing role for the different raw materials discharged from the row of quantitative conveying pipes 102; and since the return spring a405 is sleeved on the outside of the raw material mixing shaft 303, and the return spring a405 is located between the circular limiting plate 401 on the right and the raw material premixing rack 402, when the raw material mixing shaft 303 drives the raw material premixing rack 402 to rotate, the return spring a405 can push the raw material premixing rack 402 to return to the left, which also plays an axial premixing role for the different raw materials discharged from the row of quantitative conveying pipes 102.

[0030] In this embodiment of the disclosure, such as Figures 8 to 10As shown, the multi-purpose stabilizing unit 500 includes: an inclined mounting bracket 501, a stabilizing support base 502, a return spring b503, and a detection button 504; the inclined mounting bracket 501 is fixedly installed at the bottom of the raw material mixing pipe 301; the stabilizing support base 502 is slidably installed on the inclined mounting bracket 501; the return spring b503 is sleeved on the inclined mounting bracket 501, and the return spring b503 is located on the left side of the stabilizing support base 502; the detection button 504 is fixedly installed inside the stabilizing support base 502, and the detection button 504 is electrically connected to the control box 600; the multi-purpose stabilizing unit 500 includes: an inclined mounting bracket 501, a stabilizing support base 502, a return spring b503, and a detection button 504 ... The fixed unit 500 also includes: an arc-shaped pressing block 505, a guide reinforcement seat 506, and a stabilizing limit rod 507; the arc-shaped pressing block 505 is fixedly installed at the bottom of the detection button 504; there are two guide reinforcement seats 506, and the two guide reinforcement seats 506 are fixedly installed on the raw material storage box 101; there are two stabilizing limit rods 507, and the two stabilizing limit rods 507 are slidably installed on the two guide reinforcement seats 506; the left side of the two stabilizing limit rods 507 is provided with rounded corners, and the right side of the two stabilizing limit rods 507 is fixedly connected to the stabilizing support seat 502.

[0031] The specific function of the multi-purpose stabilizing unit 500 is as follows: Since the return spring b503 is sleeved on the inclined mounting bracket 501 and the return spring b503 is located on the left side of the stabilizing support 502, it provides elastic support for the stabilizing support 502, making it convenient for workers to install the raw material storage box 101 with bolts; since the inclined mounting bracket 501 is fixedly installed at the bottom of the raw material mixing pipe 301 and the stabilizing support 502 is slidably installed on the inclined mounting bracket 501, when the stabilizing support 502 slides to the left, the stabilizing support 502 slowly moves downward. Furthermore, since the detection button 504 is fixedly installed inside the stable support base 502 and electrically connected to the control box 600, and the arc-shaped pressing block 505 is fixedly installed at the bottom of the detection button 504, when the bottom of the stable support base 502 is in contact with the ground, the arc-shaped pressing block 505 presses the detection button 504. At this time, the control box 600 can control a row of servo motors a201 and b302 to work. When the bottom of the stable support base 502 is not in contact with the ground, the arc-shaped pressing block 505 cannot press the detection button 504. At this time, the control box 600 cannot control a row of servo motors. The operation of a201 and servo motor b302 ensures that the stable support base 502 is in the correct installation position. Furthermore, because the two stabilizing limit rods 507 are slidably mounted on the two guide reinforcement bases 506, and the left sides of the two stabilizing limit rods 507 are rounded, and the right sides of the two stabilizing limit rods 507 are fixedly connected to the stable support base 502, when the stable support base 502 slides to the left, the left ends of the two stabilizing limit rods 507 move to the top of the two rows of mounting bolts on the raw material storage box 101, preventing the two rows of mounting bolts on the raw material storage box 101 from loosening and ensuring that the raw material storage box 101 is in a stable state after installation.

[0032] The specific usage and function of this embodiment are as follows: In use, the raw material storage box 101 is first fixedly installed using two rows of bolts. Then, the control box 600 is connected to an external power source. Next, the stabilizing support 502 is slid to the left until its bottom contacts the ground. The stabilizing support 502 is then fixed to the ground using two bolts. When the stabilizing support 502 slides to the left, the left ends of the two stabilizing limit rods 507 move to the top of the two rows of mounting bolts on the raw material storage box 101, preventing the bolts from loosening and ensuring proper raw material storage. After installation, box 101 is in a stable state. Workers adjust the angle of a row of material dividers 104 according to the proportions of the raw materials to improve the storage efficiency of the storage box 101. Then, by tightening two rows of clamping screws 105 with a wrench, the angled material dividers 104 are clamped and positioned, ensuring their stability after rotation. Afterwards, the speed of each servo motor a201 is adjusted according to the proportions of the raw materials. When the control box 600 controls a row of servo motors a20... During operation, a row of quantitative conveying rods 202 drives a row of spiral blades a203 to rotate, allowing the raw materials in the raw material storage box 101 to be quantitatively conveyed to the raw material mixing pipe 301. When the control box 600 controls the servo motor b302 to work, the raw material mixing shaft 303 drives the raw material premixing frame 402 to rotate, which plays a radial premixing role on the different raw materials discharged from the row of quantitative conveying pipes 102. Due to the arrangement of the spiral blades b304 and the row of raw material mixing frames 305, the premixed raw materials can be automatically moved from left to right, so that the row of raw materials can be radially premixed. The material mixing rack 305 automatically mixes the premixed raw materials; when the material mixing shaft 303 drives the material premixing rack 402 to rotate, the four arc-shaped extrusion plates 404 can push the material premixing rack 402 to slide to the right a certain distance, which plays an axial premixing role on the different raw materials discharged from the row of quantitative conveying pipes 102; when the material mixing shaft 303 drives the material premixing rack 402 to rotate, the return spring a 405 can push the material premixing rack 402 to return to the left, which also plays an axial premixing role on the different raw materials discharged from the row of quantitative conveying pipes 102.
