Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a mixing equipment for various cementitious powder raw materials. Background Technology

[0002] Cementitious powder (also known as cementitious material or cementing powder) is a powder material commonly used in construction, chemical industry, environmental protection and other fields. It is a new type of cementing material used for filling in underground mines. It uses tailings as aggregate and cementitious powder as binder. Cementitious powder has the advantages of low water content, strong natural water reduction, high density, good viscosity and high later strength. It is widely used in mine filling, underground grouting, road construction and other fields.

[0003] When mixing various cementitious powder raw materials, the existing mixing equipment is inconvenient to use. It can only mix and stir the powder raw materials with a stirring paddle, and cannot crush the clumps of powder raw materials, resulting in the particle size of the raw materials not meeting the requirements for use, which affects the normal use of the mixed raw materials.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0023] In one embodiment, such as Figure 1-4 As shown, a mixing device for various cementitious powder raw materials includes a mixing tank 1, and further includes:

[0024] The grinding roller 21 is provided inside the mixing box 1, which contains a grinding box 2 and a guide cylinder 3. The grinding box 2 has a turntable 17 rotatably mounted on both sides. Multiple rotating rods 18 are rotatably mounted between the two turntables 17. The grinding roller 21 is mounted outside the rotating rods 18. The grinding box 2 has a guide plate 23 inside, which is composed of two sets of inclined plates and arc plates to support the falling raw materials. The rotating rods 18 drive the grinding roller 21 to rotate and crush the raw materials on the guide plate 23. The bottom of the guide plate 23 is provided with a filter screen 231. The bottom of the guide cylinder 3 is provided with a fixed cylinder 6. The top of the guide cylinder 3 is provided with a rotating rod 5. The fixed cylinder 6 contains a power component that can drive the rotating rod 5 to rotate. Multiple scrapers 4 are provided outside the rotating rod 5. The scrapers 4 are in contact with the top of the guide cylinder 3. The rotating rod 5 drives the scrapers 4 to rotate and stir and mix the raw materials on the guide cylinder 3.

[0025] The guide cylinder 3 has a discharge port 301, and the discharge port 301 is equipped with a baffle 20. The inner side wall of the mixing box 1 is provided with a horizontal plate 7, and a fixed sleeve 8 is provided on the horizontal plate 7. A telescopic plate 9 is provided on the fixed sleeve 8. The telescopic plate 9 is installed on the fixed sleeve 8 by bolts. The telescopic plate 9 is connected to the baffle 20. When the bolts are unscrewed, the telescopic plate 9 drives the horizontal plate 7 and the baffle 20 to descend, so that the baffle 20 is disengaged from the discharge port 301, and the mixed raw materials slide out from the discharge port 301.

[0026] The drive mechanism is connected to the turntable 17 and can drive the turntable 17 and the grinding roller 21 to rotate.

[0027] The mixing equipment for various cementitious powder raw materials drives the turntable 17 and grinding roller 21 to rotate through the drive mechanism, which can crush and grind the raw materials falling into the grinding box 2 to ensure that the particle size of the raw materials meets the requirements. The ground raw materials fall from the filter screen 231 into the guide cylinder 3. The rotating rod 5 drives the multiple scrapers 4 set on the outside to rotate and mix the raw materials. As an example, the left, right and up and down positions of the various components shown in the attached figure are only a kind of arrangement. The specific positions are set according to specific needs.

[0028] In one embodiment, such as Figure 1-4 As shown, the driving mechanism includes a fixed rod 22, a motor 26, and a rotating gear 24. A fixed frame 27 is fixedly installed on the outside of the grinding box 2. A fixed gear 25 is fixedly installed on the fixed frame 27. A rotating gear 24 that meshes with the fixed gear 25 is installed on the rotating rod 18. A motor 26 is installed on the fixed frame 27. A drive rod 22 is installed at the rotating end of the motor 26. The drive rod 22 is connected to the turntable 17. The motor 26 drives the turntable 17 and the rotating rod 18 to rotate through the drive rod 22. Since the fixed gear 25 cannot rotate, the rotating gear 24 simultaneously drives the rotating rod 18 to rotate. The grinding roller 21 rotates and grinds the raw material.

[0029] In one embodiment, such as Figure 1-2 As shown, the inner wall of the mixing box 1 is provided with an installation block 11, and a screw 14 is provided on the installation block 11. The outer wall of the grinding box 2 is provided with a fixing block 12, and the top end of the screw 14 passes through the fixing block 12 and is provided with a nut 15.

[0030] In one embodiment, such as Figure 1-2 As shown, a support sleeve 13 is sleeved on the outside of the screw 14. The support sleeve 13 is located between the fixing block 12 and the mounting block 11. The support sleeve 13 with different body heights can be replaced to facilitate the adjustment of the working height of the grinding box 2.

[0031] In one embodiment, such as Figure 1As shown, a collection box 10 is provided at the bottom of the inner cavity of the mixing box 1, and a handle 16 is provided on the collection box 10.

[0032] The present invention provides a mixing device for various cementitious powder raw materials in the above embodiments. Various cementitious powder raw materials are fed into the mixing box 1 through the feeding hopper 19. The powder raw materials fall downward into the grinding box 2. The motor 26 drives the turntable 17 and the rotating rod 18 to rotate through the drive rod 22. The grinding roller 21 rotates and grinds the raw materials. The ground raw materials fall from the filter screen 231 into the guide cylinder 3. The rotating rod 5 drives the multiple external scrapers 4 to rotate and mix the raw materials. After mixing, the bolts on the fixing sleeve 8 are unscrewed, so that the baffle 20 is separated from the guide cylinder 3, and the powder raw materials slide into the collection box 10 for collection.

[0033] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
