Description

Technical Field

[0001] This utility model relates to the field of cement preparation technology, and more specifically, to an apparatus for incorporating inert alumina into high-alumina clinker. Background Technology

[0002] High-alumina cement clinker, also known as high-alumina cement, is a fast-hardening, high-strength, heat-resistant, and corrosion-resistant cementitious material. Its main characteristics include high early strength, high temperature resistance, and corrosion resistance. High-alumina cement is mainly used for projects with tight deadlines, such as embankment construction, road construction, and special emergency repair projects. It can also be used for projects constructed in winter. When preparing high-alumina cement clinker, a certain proportion of inert alumina material needs to be added to the cement raw materials. Therefore, a device for adding inert alumina to high-alumina clinker is required.

[0003] The prior art discloses an inert alumina mixing device for cement preparation with application number CN202321365597.0. In use, this invention utilizes a pretreatment box and dispersing teeth to disperse the inert alumina material in the cement mix, preventing alumina caking and affecting the mixing effect. Simultaneously, a screen is used to sieve the dispersed material. However, the screen does not vibrate, resulting in poor sieve performance and a tendency to clog. Furthermore, the screen is located inside the pretreatment box, making disassembly and cleaning cumbersome and inconvenient once clogged, thus limiting its practicality. To address the shortcomings of this invention, those skilled in the art have proposed a device for mixing inert alumina in high-alumina clinker. Utility Model Content

This device can automatically screen the material by vibrating the screen during the addition of inert alumina material, eliminating the need for an additional vibration motor. This reduces the manufacturing cost of the device and makes the screen easier to disassemble and clean, thus improving its practicality and solving the problems mentioned in the background technology.

[0005] To achieve the aforementioned advantages of automatic sieving by vibrating a screen during the addition of inert alumina materials, eliminating the need for an additional vibration motor, reducing manufacturing costs, and facilitating screen disassembly and cleaning, thus enhancing practicality, the specific technical solution adopted by this utility model is as follows: A device for adding inert alumina to high-alumina clinker includes a mixing tank. A mixing shaft is installed inside the mixing tank, and mixing rods are evenly fixedly mounted on the mixing shaft. A scraper is fixedly connected to one end of each mixing rod. A motor base is fixedly mounted on one side wall of the mixing tank, and a servo motor is mounted on the motor base. The output end of the servo motor is connected to one end of the mixing shaft. The top of the mixing tank is fixedly... The mixing tank is equipped with a mounting frame, on which a pretreatment box is mounted. Several mounting blocks are symmetrically fixedly mounted on the inner wall of the mixing tank, and several telescopic rods are mounted on the top surface of the mounting blocks. A vibrating frame is connected to the movable end of the telescopic rod.

A second pulley is fixedly mounted on one end of the striking shaft. Two first pulleys are fixedly mounted on the mixing shaft, and a first transmission belt is sleeved between the first pulley and the second pulley.

[0006] Furthermore, a dispersing shaft is installed inside the pretreatment box, and several dispersing teeth are evenly fixedly installed on the dispersing shaft. A fourth pulley is fixedly installed at one end of the dispersing shaft, and a third pulley is fixedly installed at one end of the stirring shaft. A second transmission belt is sleeved between the third pulley and the fourth pulley. A discharge pipe is connected to the center of the bottom of the pretreatment box.

[0007] Furthermore, several discharge pipes are connected to the bottom of the inner cavity of the mixing tank, and discharge valves are installed on the discharge pipes.

[0008] Furthermore, a control panel is installed on the side wall of the mixing tank, and the control panel is electrically connected to the servo motor and the discharge valve.

[0009] Furthermore, the bottom cross-sectional shape of the mixing tank is semi-circular.

[0010] Furthermore, a pull ring is symmetrically and fixedly installed on the top surface of the screen.

[0011] Furthermore, a support frame is fixedly installed on the bottom plate of the mixing tank.

[0012] Compared with the prior art, this utility model provides a device for incorporating inert alumina into high-alumina clinker, which has the following beneficial effects:

[0013] (1) This utility model is equipped with a mixing box and a pretreatment box. The mixing box has a mixing shaft installed inside, and mixing rods are evenly fixedly installed on the mixing shaft. A scraper is fixedly connected to one end of the mixing rod. A motor base is fixedly installed on one side wall of the mixing box, and a servo motor is installed on the motor base. The output end of the servo motor is connected to one end of the mixing shaft. A mounting frame is fixedly installed on the top of the mixing box, and a pretreatment box is installed on the mounting frame. A dispersing shaft is installed inside the pretreatment box, and several dispersing teeth are evenly fixedly installed on the dispersing shaft. A fourth pulley is fixedly installed at one end of the dispersing shaft. A third pulley is fixedly installed at one end of the mixing shaft, and a second transmission belt is sleeved between the third pulley and the fourth pulley. In use, the worker puts cement material into the mixing box and then... A predetermined proportion of inert alumina is introduced into the pretreatment tank. Then, a servo motor is started to drive the stirring shaft and stirring rod to rotate. The rotation of the stirring shaft drives the dispersing shaft to rotate, which in turn drives the dispersing teeth to disperse the inert alumina material in the pretreatment tank. The dispersed inert alumina material falls into the inner cavity of the mixing tank through the discharge pipe, thus incorporating the inert alumina into the cement material.

A screen is embedded in the center of the vibrating frame, and a pull ring is symmetrically fixedly installed on the top surface of the screen. On the other hand, striking shafts are symmetrically installed on the side wall of the mixing tank, and eccentric striking wheels are fixedly installed on the striking shafts. A second pulley is fixedly installed at one end, and two first pulleys are fixedly installed on the stirring shaft. A first transmission belt is sleeved between the first and second pulleys. Therefore, when the stirring shaft rotates, it can drive the two striking shafts to rotate synchronously.

Therefore, when the dispersed inert alumina material falls into the inner cavity of the mixing tank, it can be screened by the vibrating screen without the need for an additional vibrating motor. This helps to reduce the manufacturing cost of the device, and the screen is easier to disassemble and clean, making it more practical. Attached Figure Description
