Description

Technical Field

[0001] This utility model relates to the field of mineral blending technology, and in particular to a device for blending dissimilar mineral admixtures. Background Technology

[0002] Adding mineral admixtures to concrete can improve its durability. In some concrete structures with anti-corrosion requirements, fly ash mineral admixtures can be added. The active components in fly ash can undergo a secondary hydration reaction with calcium hydroxide produced by cement hydration, generating cementitious products that fill the pores inside the concrete, making the concrete structure more compact. This can effectively prevent the intrusion of corrosive media such as chloride ions, thereby improving the concrete's resistance to chloride ion erosion and sulfate erosion.

[0003] A search revealed Chinese Patent Publication No. CN218531738U, which discloses a material distribution device for processing composite mineral admixtures, relating to the field of mineral production and processing technology. The device includes a cover plate, a feed hopper fixedly installed on the top of the cover plate, a shell threadedly connected to the bottom of the cover plate, a movable door movably installed on the front of the shell, a coarse material outlet fixedly installed on the right side of the shell, a fine material outlet fixedly installed on the bottom right side of the shell near the coarse material outlet, movable devices fixedly installed at the four corners of the bottom of the shell, a first support rod fixedly installed at the bottom of the cover plate, a conical partition fixedly installed at the bottom of the first support rod, and a first spring fixedly installed on the inner wall of the shell. This utility model allows for the separation of the cover plate and the outer shell, facilitating the cleaning and maintenance of the material distribution device for processing composite mineral admixtures. A screen is attached to the side of the third support, which can be pulled out from the upper side for easy cleaning and replacement. In actual use, the device mixes multiple materials together, but the particle size of the materials varies, resulting in uneven mixing and reduced quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mixing device for dissimilar mineral admixtures, which aims to improve the problem in the prior art where the particle size of the mixture is inconsistent, resulting in uneven mixing during the stirring process and reduced quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing device for dissimilar mineral admixtures, comprising a mixing box, a crushing box fixedly connected to the top of the mixing box, a top cover provided on the top of the crushing box, a motor connected to the top of the top cover, the output end of the motor penetrating the top cover and fixedly connected to a rotating rod, a rotating blade fixedly connected to the outer wall of the rotating rod, a fixed blade fixedly connected to the inner wall of the crushing box, a filter screen fixedly connected to the bottom of the crushing box, a rotating plate fixedly connected to the bottom end of the rotating rod penetrating the filter screen, a stirring rod rotatably connected to both ends of the bottom of the rotating plate, a discharge port communicating with the front bottom of the mixing box, and a cleaning mechanism provided inside the mixing box.

[0006] The above technical solution involves: first, placing the dissimilar mineral raw materials to be blended into the crushing chamber, then closing the top cover and starting the motor. The motor's output drives the rotating rod to rotate at high speed, causing the rotating blades on the outer wall of the rotating rod to rotate accordingly. These blades, in conjunction with the fixed blades fixedly connected to the inner wall of the crushing chamber, cut and crush the mineral raw materials. Under the combined action of the rotating blades and the fixed blades, large pieces of mineral raw materials are gradually crushed into smaller particles. The crushed mineral particles undergo preliminary screening through a filter screen at the bottom of the crushing chamber. Particles meeting the particle size requirements fall into the blending chamber. At this point, the rotating rod continues to rotate, driving the rotating plate at its bottom to rotate. The stirring rods, connected to both ends of the rotating plate, stir within the blending chamber as the rotating plate rotates, thoroughly mixing and blending the mineral particles that fall into the blending chamber with other blending materials that may have been pre-placed in the blending chamber. Finally, the blended material can be discharged through the outlet at the front of the bottom of the blending chamber for subsequent use or processing, thus improving production efficiency and product quality stability.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes multiple fixed plates, one side of each fixed plate is fixedly connected to the outer wall of the mixing tank, one side of each fixed plate is provided with a moving groove, the top of the inner side of each moving groove is fixedly connected with a telescopic rod, the other end of each telescopic rod is fixedly connected with a moving block, and one side of each moving block is fixedly connected with the same annular scraper.

[0009] The above technical solution works as follows: when it is necessary to clean the inner wall of the mixing tank, the relevant control device is activated to make the telescopic rod start working. The telescopic rod extends, and the moving block fixedly connected to one end moves downward in the moving groove opened on one side of the fixed plate. Since multiple moving blocks are fixedly connected to the annular scraper, the annular scraper also moves downward. During the downward movement, the annular scraper comes into close contact with the inner wall of the mixing tank, and the sharp edge of the scraper scrapes off the mineral residue, dust and impurities attached to the tank wall.

[0010] As a further description of the above technical solution:

[0011] A support is fixedly connected to the outer wall of the mixing tank, and a base is fixedly connected to the bottom of the support.

[0012] The above technical solution involves: the support frame elevating the mixing tank, raising the device to a certain height above the ground for easy material discharge, and the base providing a stable support foundation to ensure the stability of the entire device during operation.

[0013] As a further description of the above technical solution:

[0014] A switch is fixedly connected to the front side of the bracket, and the switch is electrically connected to the motor and the telescopic rod respectively.

[0015] The above technical solution involves an electrical connection between the motor and the telescopic rod, allowing for convenient control of the motor's start and stop via an operating switch.

[0016] As a further description of the above technical solution:

[0017] An observation window is provided on the front side of the crushing box, and a sealing frame is fixedly connected to the front side of the observation window.

[0018] The above technical solution allows operators to directly observe the crushing process of mineral raw materials inside the crushing chamber through the observation window, while the sealing frame seals the observation window.

[0019] As a further description of the above technical solution:

[0020] A feed inlet is provided at the upper rear side of the crushing box, and a feed box is fixedly connected to the rear side of the crushing box.

[0021] The above technical solution involves fixing the feed box to the rear of the crushing box, which guides and accommodates the mineral raw materials, allowing the mineral raw materials to be conveniently placed in the feed box.

[0022] As a further description of the above technical solution:

[0023] A circular ring is fixedly connected to the top inner side of the mixing tank, and arc-shaped grooves are opened at both ends of the top of the rotating plate.

[0024] The above technical solution involves fixing the ring to the top inner side of the mixing tank, with the arc-shaped grooves at both ends of the top of the rotating plate engaging with it.

[0025] As a further description of the above technical solution:

[0026] The top cover is fixedly connected with slots at equal intervals around its perimeter, and the outer wall of the crushing box is fixedly connected with buckles at equal intervals on its top surface.

[0027] The above technical solution uses slots and buckles to connect the top cover and the crushing chamber.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the rotating rod is driven by a motor to rotate, so that the rotating blade and the fixed blade cooperate to cut and crush the mineral raw materials in the crushing box. After being screened by the filter screen, the particles fall into the mixing box. The rotating plate and the stirring rod then mix them evenly with the admixtures in the box. Finally, the material is discharged from the outlet, realizing the efficient and stable blending and processing of dissimilar mineral admixtures, improving production efficiency and product quality.

[0030] 2. In this utility model, the telescopic rod is activated by starting the control device. Its extension drives a moving block fixed at one end to move downward in the moving groove of the fixed plate. Since multiple moving blocks are connected to the annular scraper, the annular scraper moves downward synchronously. During the movement, the annular scraper is in close contact with the inner wall of the mixing tank, thus achieving the cleaning purpose of scraping off mineral residues, dust and other impurities on the tank wall by utilizing the sharpness of the scraper.

[0038] 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a device for blending dissimilar mineral admixtures, comprising a blending box 1 for containing and initially mixing admixtures, a crushing box 3 fixedly connected to its top, the crushing box 3 for crushing large mineral raw materials, a top cover 4 for sealing the top opening of the crushing box 3, a motor 5 connected to the top of the top cover 4 for powering the operation of the entire device, the output end of the motor 5 passing through the top cover 4 and fixedly connected to a rotating rod 6 for transmitting the rotational power of the motor 5, a rotating blade 7 fixedly connected to the outer wall of the rotating rod 6, the rotating blade 7 working in conjunction with a fixed blade 8 fixedly connected to the inner wall of the crushing box 3 to cut and crush the mineral raw materials, the fixed blade 8 fixedly connected to the inner wall of the crushing box 3, the two working together to crush the minerals, a filter screen 9 fixedly connected to the bottom of the crushing box 3 for screening out crushed materials that meet the particle size requirements. The bottom end of the rotating rod 6 passes through the filter screen 9 and is fixedly connected to the rotating plate 10. The rotating plate 10 can drive the stirring rod 11 to rotate. The bottom ends of the rotating plate 10 are rotatably connected to the stirring rod 11. The stirring rod 11 can stir and mix the materials in the mixing box 1. The bottom front side of the mixing box 1 is connected to the discharge port 12, which facilitates the discharge of the mixed materials. The mixing box 1 is equipped with a cleaning mechanism 2, which can clean the impurities on the inner wall of the mixing box 1. The upper middle part of the rear side of the crushing box 3 is provided with a feed port 18, which is the channel for mineral raw materials to enter the crushing box 3. The rear side of the crushing box 3 is fixedly connected to the feed box 19, which is used to temporarily store and guide mineral raw materials into the crushing box 3. The top cover 4 is fixedly connected with slots 22 at equal intervals around its perimeter. The slots 22 cooperate with the buckles 23 fixedly connected at equal intervals on the top of the outer wall of the crushing box 3, which can realize the firm connection and convenient disassembly of the top cover 4 and the crushing box 3.

[0040] Specifically, first, the dissimilar mineral raw materials to be blended are placed in the crushing chamber 3, then the top cover 4 is closed, and the motor 5 is started. The output end of the motor 5 drives the rotating rod 6 to rotate at high speed. The rotating blade 7 on the outer wall of the rotating rod 6 rotates accordingly, and the fixed blade 8, which is fixedly connected to the inner wall of the crushing chamber 3, works together to cut and crush the mineral raw materials. Under the combined action of the rotating blade 7 and the fixed blade 8, large pieces of mineral raw materials are gradually crushed into smaller particles. The crushed mineral particles are initially screened through the filter screen 9 at the bottom of the crushing chamber 3. Particles that meet the particle size requirements fall into the blending chamber 1. At this time, the rotating rod 6 continues to rotate and drives the rotating plate 10 at its bottom to rotate. The stirring rods 11, which are rotatably connected to both ends of the bottom of the mixing box 1, perform a stirring action in the mixing box 1 as the rotating plate 10 rotates. This fully mixes and blends the mineral particles falling into the mixing box 1 with other admixtures that may have been pre-placed in the mixing box 1. Finally, the blended material can be discharged through the discharge port 12 on the front side of the bottom of the mixing box 1 for subsequent use or processing operations, which improves production efficiency and product quality stability. The feed port 18 is the channel for mineral raw materials to enter the crushing box 3. The feed box 19 is fixed on the rear side of the crushing box 3 and serves to guide and contain the mineral raw materials. The slot 22 and the buckle 23 are used to connect the top cover 4 and the crushing box 3.

[0041] Reference Figure 2 and Figure 5 The cleaning mechanism 2 includes multiple fixed plates 201, which provide a stable installation base for the cleaning mechanism 2. One side of each fixed plate 201 is fixedly connected to the outer wall of the mixing tank 1, thereby connecting the cleaning structure to the mixing tank 1. Each fixed plate 201 has a moving groove 202 on one side, which provides a guide path for the up and down movement of the moving block 204. Each moving groove 202 has a telescopic rod 203 fixedly connected to the top of its inner side. The telescopic rod 203 can move the moving block 204 by telescopic movement. The other end of each telescopic rod 203 is fixedly connected to the moving block 204, which can slide smoothly up and down in the moving groove 202. Each moving block 204 has the same annular scraper 205 fixedly connected to one side. The annular scraper 205 can scrape off the residual materials and other impurities on the inner wall of the mixing tank 1 during movement.

[0042] Specifically, when it is necessary to clean the inner wall of the mixing tank 1, the relevant control device is activated to make the telescopic rod 203 start working. The telescopic rod 203 extends, and the movable block 204 fixedly connected to one end moves downward in the movable groove 202 opened on one side of the fixed plate 201. Since multiple movable blocks 204 are fixedly connected to the annular scraper 205, the annular scraper 205 also moves downward. During the downward movement, the annular scraper 205 comes into close contact with the inner wall of the mixing tank 1, and the sharp edge of the scraper scrapes off the mineral residue, dust and impurities attached to the tank wall.

[0043] Reference Figure 1 and Figure 4 A support frame 13 is fixedly connected to the outer wall of the mixing tank 1. The support frame 13 supports the mixing tank 1 and maintains a certain distance from the ground. A base 14 is fixedly connected to the bottom of the support frame 13, providing a stable support foundation for the entire device. A switch 15 is fixedly connected to the front of the support frame 13. The switch 15 serves as a control component, facilitating the operator to control the motor 5 and the telescopic rod 203. The switch 15 is electrically connected to both the motor 5 and the telescopic rod 203 to transmit power and control their operation. The crushing box 3... An observation window 16 is provided on the front side, which allows the operator to directly observe the situation inside the crushing box 3. A sealing frame 17 is fixedly connected to the front side of the observation window 16. The sealing frame 17 can prevent the material inside the crushing box 3 from leaking out of the observation window 16. A ring 20 is fixedly connected to the top of the inner side of the mixing box 1. The ring 20 can cooperate with the arc grooves 21 opened at both ends of the top of the rotating plate 10. Arc grooves 21 are opened at both ends of the top of the rotating plate 10. The cooperation between the arc grooves 21 and the ring 20 can make the rotating plate 10 more stable and accurately positioned when rotating.

[0044] Specifically, the bracket 13 supports the mixing tank 1, raising the device a certain height off the ground for easy material discharge and other operations. The base 14 provides a stable support foundation. The motor 5 can be easily started and stopped by the operating switch 15. The observation window 16 allows the operator to directly see the crushing of the mineral raw materials in the crushing box 3. The ring 20 is fixed to the inner top of the mixing tank 1, and the arc grooves 21 at both ends of the top of the rotating plate 10 cooperate with it to position and stabilize the rotating plate 10, preventing the rotating plate 10 from shifting during the mixing process.

[0045] Working Principle: When using the dissimilar mineral admixture blending device, first, the dissimilar mineral raw materials to be blended are placed in the crushing chamber 3, then the top cover 4 is closed, and the motor 5 is started. The output end of the motor 5 drives the rotating rod 6 to rotate at high speed. The rotating blade 7 on the outer wall of the rotating rod 6 rotates accordingly, cooperating with the fixed blade 8 fixedly connected to the inner wall of the crushing chamber 3 to cut and crush the mineral raw materials. Under the combined action of the rotating blade 7 and the fixed blade 8, large pieces of mineral raw materials are gradually crushed into smaller particles. The crushed mineral particles are initially screened through the filter screen 9 at the bottom of the crushing chamber 3. Particles that meet the particle size requirements fall into the blending chamber 1. At this time, the rotating rod 6 continues to rotate and drives the rotating plate 10 at its bottom end to rotate. The stirring rod 11, which is rotatably connected to both ends of the bottom of the rotating plate 10, performs a stirring action in the blending chamber 1 with the rotation of the rotating plate 10, stirring the minerals falling into the blending chamber 1. The particles are thoroughly mixed and blended with other materials that may be pre-placed in the mixing tank 1. Finally, the blended material can be discharged through the discharge port 12 at the bottom front of the mixing tank 1 for subsequent use or processing, which improves production efficiency and product quality stability. When it is necessary to clean the inner wall of the mixing tank 1, the relevant control device is activated to start the telescopic rod 203. The telescopic rod 203 extends, and the moving block 204 fixedly connected to one end moves downward in the moving groove 202 opened on one side of the fixed plate 201. Since multiple moving blocks 204 are fixedly connected to the annular scraper 205, the annular scraper 205 also moves downward. During the downward movement, the annular scraper 205 comes into close contact with the inner wall of the mixing tank 1, and the sharp edge of the scraper scrapes off the mineral residues, dust and impurities attached to the tank wall.
