Description

Technical Field

[0001] The utility model relates to the technical field of corundum material mixers, in particular to a countercurrent wear-resistant corundum material mixer. Background Art

[0002] In the field of refractory materials, improving the high-temperature resistance and erosion resistance of corundum products requires precise mixing of corundum with other refractory additives. In the field of abrasives, mixing corundum with an appropriate resin binder can enhance the moldability and grinding performance of the abrasive tools. Therefore, efficient and uniform mixing plays a vital role in the quality and performance of corundum materials.

[0003] Many traditional mixers suffer from significant uneven mixing when mixing corundum. Due to the high hardness and poor fluidity of corundum particles, material stratification is prone to occur during the drum rotation process, affecting the performance consistency of the corundum products.

[0004] The structural design of traditional mixers often fails to fully utilize the material's flow characteristics to improve mixing efficiency. For example, some single-shaft mixers have a single rotational direction, preventing convection during mixing. This causes the material to aggregate and stratify, resulting in long mixing times and poor mixing results. When mixing large quantities of corundum, the material's quality must also be considered. To achieve the same mixing effect with a higher mass, greater stirring power is required, resulting in greater wear on the impeller and cylinder. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a counter-current wear-resistant corundum material mixer.

[0006] The technical solution of the utility model is a countercurrent wear-resistant corundum material mixer, which includes a main barrel, a liner barrel rotatably arranged in the main barrel, a mounting plate fixedly arranged on the liner barrel, a stirring paddle arranged on the mounting plate and located at an eccentric position inside the liner barrel, a pre-storage barrel arranged directly above the main barrel through a support rod, and a material control plate rotatably sealed and arranged at the bottom of the pre-storage barrel; a weighing sensor and a discharge valve are arranged at the bottom of the liner barrel;

[0007] A first gear ring is provided on the lining barrel, a second gear ring is provided on the material control disk, a motor is provided on one side of the main barrel, and the output end of the motor is engaged with the first gear ring and the second gear ring respectively; there are multiple cavities in the pre-storage barrel, and a through hole is provided at the bottom of each cavity; a groove body is provided at the bottom of the material control disk, which can be connected with the through hole.

[0008] Description: The material to be mixed is pre-stored in the pre-storage barrel, the lining barrel is driven to rotate by the engagement of the motor and the first gear ring, and the material in the lining barrel is stirred by the stirring paddle; the material control disk is driven to rotate by the motor and the second gear ring. Due to the different tooth spacing of the gear rings, the rotation speed of the pre-storage barrel and the material control disk is also different; the materials in different cavities in the pre-storage barrel fall in turn, and since the lining barrel is constantly rotating, the materials in different cavities can be made to fall evenly in the lining barrel, thereby improving the mixing efficiency.

[0009] Furthermore, an annular convex strip is provided on the material control disk, and an annular groove is provided on the bottom of the pre-storage barrel, and the annular convex strip is slidably sealed and clamped with the annular groove.

[0010] Description: The cooperation between the annular rib and the annular groove realizes the rotational sealing connection between the pre-storage barrel and the material control disc, ensuring the docking and communication between the through hole and the groove body.

[0011] Furthermore, a third gear ring meshing with the first gear ring and a fourth gear ring meshing with the second gear ring are coaxially arranged at the output end of the motor; the tooth spacing of the first gear ring is different from that of the second gear ring.

[0012] Description: The first gear ring is meshed with the third gear ring, and the second gear ring is meshed with the fourth gear ring, which can make the rotation speed of the pre-storage barrel and the material control disk inconsistent, so that the two have relative movement, making the corundum material fall more evenly and improving the pre-mixing effect.

[0013] Furthermore, the tank body is provided with an electric control valve for controlling the size of the tank body opening.

[0014] Note: By controlling the size of the tank opening through the electric control valve, the falling speed of each material can be controlled, making it easy to adjust the device to the best mixing efficiency.

[0015] Furthermore, sieve plates with different mesh sizes are provided on the plurality of trough bodies in a one-to-one correspondence.

[0016] Description: By cooperating with the electric control valve to open different troughs, sieve plates with various mesh sizes can be quickly replaced and adaptively adjusted according to the needs of use. The screening function is realized before stirring, which improves the processing efficiency.

[0017] The beneficial effects of the present invention are as follows: the through hole of the pre-storage barrel of the present invention is intermittently connected with the trough body at the bottom of the material control disk, and due to the continuous rotation of the liner barrel, the materials in different cavities in the pre-storage barrel can be evenly distributed in the liner barrel; this uniform falling method avoids the accumulation of materials in a certain area and the occurrence of stratification, so that the initial distribution of different materials in the liner barrel is relatively uniform, providing a good foundation for subsequent stirring and mixing, thereby improving the uniformity of mixing; the falling amount of each material can be controlled by adjusting the rotation speed of the material control disk, and the corundum material in the liner barrel is controlled as a whole through the weighing sensor and the discharge valve port, so that the corundum material in the liner barrel is always kept in a lower quality range, which not only enhances the mixing effect, but also avoids the wear of the stirring paddle by a large amount of corundum material, and reduces the power required for stirring.

DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0025] Example 1: Figure 1 、 2 The countercurrent wear-resistant corundum material mixer shown in the figure includes a main barrel 1, a liner barrel 2 rotatably disposed within the main barrel 1, a mounting plate 3 fixedly disposed on the liner barrel 2, a stirring paddle 4 disposed on the mounting plate 3 and located eccentrically within the liner barrel 2, a pre-storage barrel 6 disposed directly above the main barrel 1 via a support rod 5, and a material control plate 7 rotatably sealed at the bottom of the pre-storage barrel 6; a weighing sensor and a discharge valve are disposed at the bottom of the liner barrel 2;

[0026] The stirring paddle 4 is equipped with a rotary motor for driving the blades;

[0027] The lining barrel 2 is provided with a first gear ring 21, the material control plate 7 is provided with a second gear ring 71, and a motor 8 is provided on one side of the main barrel 1. The output end of the motor 8 is meshed with the first gear ring 21 and the second gear ring 71 respectively;

[0028] The output end of the motor 8 is coaxially provided with a third gear ring 81 meshing with the first gear ring 21 and a fourth gear ring 82 meshing with the second gear ring 71; the tooth pitch of the first gear ring 21 is different from that of the second gear ring 71; the gear ratio of the second gear ring 71 to the first gear ring 21 is 3:1;

[0029] The pre-storage barrel 6 has multiple cavities, and each cavity is provided with a through hole 61 at the bottom; the control plate 7 is provided with a groove 72 at the bottom that can be connected to the through hole 61; the groove 72 is provided with an electric control valve for controlling the opening size of the groove 72;

[0030] The material control plate 7 is provided with an annular convex strip, and the bottom of the pre-storage barrel 6 is provided with an annular groove, and the annular convex strip is slidably and sealedly engaged with the annular groove.

[0031] It should be noted that: this embodiment also includes a power supply and a controller, and the power supply, the controller, the rotary motor, the motor 8, the electric control valve, the stirring paddle 4, the weighing sensor and the discharge valve are all commercially available products, and are not described in detail here;

[0032] The rotating motor, the motor 8, the electrically controlled valve, the weighing sensor and the discharge valve port in this embodiment are all electrically connected to the power supply and the controller respectively.

[0033] The working principle of this embodiment is as follows: the through hole 61 of the pre-storage barrel 6 is intermittently connected with the groove body 72 at the bottom of the material control disk 7, and the lining barrel 2 rotates continuously. The first gear ring 21 is meshed with the third gear ring 81 and the second gear ring 71 is meshed with the fourth gear ring 82, so that the rotation speed of the pre-storage barrel 6 and the material control disk 7 can be different, so that the materials in different cavities of the pre-storage barrel 6 fall into the lining barrel 2 in turn and fall evenly, avoiding concentrated accumulation and stratification, so that the materials are initially evenly distributed. At the same time, the falling amount of each material is controlled by adjusting the rotation speed of the material control disk 7 to achieve a precise feeding ratio, and the overall amount of corundum material in the lining barrel 2 is controlled by the weighing sensor and the discharge valve port to keep it in a low range. This not only provides a good foundation for subsequent stirring and mixing to improve the mixing uniformity, but also avoids a large amount of corundum material wearing the stirring paddle and reducing the stirring power.

[0034] Example 2: Figure 3As shown, this embodiment differs from the first embodiment in that the third gear ring 81 is not provided. Instead, the motor 8, located between the output end of the motor 8 and the first gear ring 21, is further provided with a transmission gear 83 for changing the direction of rotation of the liner drum 2. A ring gear is provided at the output end of the motor 8 that meshes with the transmission gear 83, which also meshes with the first gear ring 21. The transmission gear can change the rotation direction of the liner drum, making the rotation direction of the liner drum inconsistent with that of the material control plate, thereby enhancing the uniformity of the falling corundum material and further improving the pre-mixing effect of the material.

[0035] Example 3: This example is different from Example 1 in that sieve plates with different mesh sizes are provided on the three trough bodies 72 in a one-to-one correspondence, and the sieve plates are commercially available 50-mesh sieve plates, 100-mesh sieve plates, and 300-mesh sieve plates.
