Description

Technical Field

[0001] This utility model relates to the field of material grinding technology, and in particular to a grinding device for the production of steel slag-based solid waste cementitious materials. Background Technology

[0002] Steel slag-based solid waste cementitious material is an environmentally friendly cementitious material made primarily from steel slag, combined with other solid waste materials (such as fly ash, slag, and gypsum). It not only utilizes the resources of steel slag but also effectively treats various industrial solid wastes, possessing significant environmental and economic value. The production process of steel slag-based solid waste cementitious material requires grinding the raw materials.

[0003] A grinding device for ultra-low carbon and ultra-low emission solid waste cementitious materials, disclosed in announcement number CN220835735U, provides a method for grinding solid waste materials. This method uses a second motor to control the rotation of the grinding rollers, thereby grinding the solid waste materials. The ground solid waste materials are filtered through a screen into a powder collection box, with some incompletely ground solid residue remaining on the screen. Then, a first motor drives a threaded rod to rotate, causing a cleaning pusher on the threaded rod to move outwards, pushing out the solid residue on the screen. The cover is then opened to collect and clean the solid residue at the cleaning port, before it is poured back into the feed inlet for secondary grinding. By repeatedly grinding, cleaning, and collecting the solid waste materials through this device, the pass rate of the powdered materials can be greatly improved, making them more suitable for application.

[0004] However, this ultra-low carbon and ultra-low emission all-solid waste cementitious material grinding device has the following disadvantages: the grinding is carried out by rotating grinding rollers to shear and crush the material in one pass, which results in low grinding efficiency, difficulty in producing fine powder, and greater wear on the grinding rollers, affecting their service life.

[0015] (III) Beneficial Effects

[0016] This utility model provides a grinding device for the production of steel slag-based solid waste cementitious materials, which has the following beneficial effects:

[0017] 1. This grinding device for producing steel slag-based solid waste cementitious materials uses a uniform feeding mechanism to feed the steel slag-based solid waste cementitious materials into the material chamber. Connecting to an external power source, servo motor B drives the feeding auger to rotate, stably outputting the material from the feeding pipe and preventing blockage during feeding.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a grinding device for producing steel slag-based solid waste cementitious materials, including a grinding chamber 1. An A servo motor 2 is fixedly installed on the bottom surface of the grinding chamber 1. A multi-stage grinding assembly 3 is fixedly installed at the output end of the A servo motor 2. Through the setting of the multi-stage grinding assembly 3, the A servo motor 2 drives a large-diameter grinding disc 302, a medium-diameter grinding disc 303, and a small-diameter grinding disc 304 to rotate in the grinding ring 10. The material first passes through the small-diameter grinding disc 304 for initial grinding, then enters the medium-diameter grinding disc 303 for secondary grinding, and finally enters the large-diameter grinding disc 302 for fine grinding. The multi-stage grinding method makes the material grinding more refined and efficient, and also reduces the requirements and wear of the grinding discs, thus extending their service life.

[0027] A rotating disk 4 is fixedly installed on the top surface of the multi-stage grinding assembly 3. A uniform feeding mechanism 5 is fixedly installed on the top surface of the rotating disk 4. Through the uniform feeding mechanism 5, the steel slag-based solid waste cementitious material is fed into the material chamber 7. When connected to an external power source, the B servo motor 901 drives the feeding auger 903 to rotate, and the material is stably output from the feeding pipe 11 to avoid clogging when feeding material into the feeding pipe 11. The A servo motor 2 drives the uniform feeding mechanism 5 to rotate. The centrifugal force generated when the material-dispensing plate 502 rotates will evenly throw the material into the grinding chamber 1 to avoid the material accumulating in the central area and causing clogging. Slow feeding in the grinding ring 10 will affect the subsequent grinding efficiency.

[0028] A fixed frame 6 is fixedly installed on both sides of the top surface of the grinding chamber 1. A material chamber 7 is fixedly installed on one side of the fixed frame 6. A support frame 8 is fixedly installed on the top surface of the material chamber 7. A feeding mechanism 9 is fixedly installed on the top surface of the support frame 8. A grinding ring channel 10 is fixedly installed on the inner wall of the grinding chamber 1.

[0029] The multi-stage grinding assembly 3 includes a rotating shaft 301 fixedly mounted on the output end of servo motor A 2. A large-diameter grinding disc 302 is fixedly mounted on the bottom of the surface of the rotating shaft 301, a medium-diameter grinding disc 303 is fixedly mounted on the middle of the surface of the rotating shaft 301, and a small-diameter grinding disc 304 is fixedly mounted on the top of the surface of the rotating shaft 301.

[0030] By setting up the multi-stage grinding component 3, the multi-stage grinding method makes the material grinding more refined and efficient, and also reduces the requirements and wear on the grinding disc, thus extending its service life.

[0031] The uniform feeding mechanism 5 includes a rotating cone 501 fixedly disposed on the top surface of the rotating disk 4, and feeding plates 502 are fixedly disposed in a ring array around the surface of the rotating cone 501.

[0032] With the uniform feeding mechanism 5 in place, servo motor A 2 drives the uniform feeding mechanism 5 to rotate. The centrifugal force generated when the material feeding plate 502 rotates evenly throws the material into the grinding chamber 1, avoiding material accumulation in the central area and causing congestion.

[0033] The feeding mechanism 9 includes a B servo motor 901 fixedly installed on the top surface of the support frame 8. A connecting rod 902 is fixedly installed at the output end of the B servo motor 901, and a feeding auger rod 903 is fixedly installed at the bottom of the connecting rod 902.

[0034] With the setting of the feeding mechanism 9, the B servo motor 901 drives the feeding auger rod 903 to rotate, so as to stably output the material from the feeding pipe 11 and avoid congestion when feeding the material from the feeding pipe 11.

[0035] The grinding ring channel 10 consists of three groups distributed along the axial direction from top to bottom on the inner wall of the grinding chamber 1. The large-diameter grinding disc 302, the medium-diameter grinding disc 303, and the small-diameter grinding disc 304 are respectively rotatably arranged inside the three groups of grinding ring channels 10.

[0036] The grinding ring 10 is designed to work in conjunction with the large-diameter grinding disc 302, the medium-diameter grinding disc 303, and the small-diameter grinding disc 304 to perform graded grinding of steel slag-based solid waste cementitious materials.

[0037] A feeding pipe 11 is fixedly installed in the middle of the bottom surface of the material chamber 7, and a control valve is fixedly installed on the surface of the feeding pipe 11.

[0038] The feeding pipe 11 serves to feed materials into the grinding chamber 1.

[0039] A powder outlet pipe 12 is fixedly installed on one side of the bottom surface of the grinding chamber 1, and support legs 13 are fixedly installed in a circular array around the bottom surface of the grinding chamber 1.

[0040] The powder outlet pipe 12 is designed to discharge fine powder.

[0041] In this invention, the working steps of the device are as follows:

[0042] First step: Put the steel slag-based solid waste cementitious material into the material chamber 7, connect the external power supply, and drive the feeding auger rod 903 to rotate, so that the material is stably output from the feeding pipe 11, avoiding congestion when feeding material into the feeding pipe 11.

[0043] Second step: A servo motor 2 drives the uniform feeding mechanism 5 to rotate. The centrifugal force generated when the material feeding plate 502 rotates will evenly throw the material into the grinding chamber 1, avoiding material accumulation in the central area and causing congestion. Slow feeding in the grinding ring 10 will affect the subsequent grinding efficiency.

[0044] The third step: Servo motor 2 drives the large-diameter grinding disc 302, the medium-diameter grinding disc 303, and the small-diameter grinding disc 304 to rotate within the grinding ring 10. The material first undergoes initial grinding on the small-diameter grinding disc 304, then enters the medium-diameter grinding disc 303 for secondary grinding, and finally enters the large-diameter grinding disc 302 for fine grinding. This multi-stage grinding method makes the material grinding more refined and efficient, and also reduces the requirements and wear on the grinding discs, thus extending their service life.
