[0002] Coal gangue is solid waste generated during coal mining and washing. It has a certain calorific value and chemical activity and can be used to prepare building materials, generate electricity, etc. Coal gangue mortar is a method of using coal gangue as raw material to make fine particles that can be used for construction through crushing, screening, mixing, drying and other processes. Coal gangue mortar can not only realize the resource utilization of coal gangue and reduce environmental pollution, but also save traditional building materials such as cement and sand, reduce costs and improve efficiency;

[0003] At present, there are many processes and equipment for preparing mortar from coal gangue. The existing equipment can use self-igniting coal gangue powder as raw material, and through chemical activation, preparation, drying and other steps, prepare different grades of coal gangue dry-mixed mortar. The maximum replacement amount of coal gangue powder can reach 60%, and it can be made into artificial sand and gravel aggregate with good mechanical properties and durability, which can be used to prepare concrete, etc.

[0004] However, the existing process and equipment for preparing mortar from coal gangue still have some shortcomings. For example, the equipment for preparing mortar from coal gangue generally adopts a tower-type structure, the equipment is high, and occupies a large area, which makes the equipment inconvenient to repair and overhaul, requiring climbing and descending, and has a low safety factor and low work efficiency.

[0028] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0029] like Figure 1-7As shown, a stepped production device for preparing mortar from coal gangue comprises a feeding port 1, a first elevator 3 is arranged on one side of the feeding port 1, a belt conveyor 2 is arranged between the feeding port 1 and the first elevator 3, a side of the first elevator 3 away from the feeding port 1 is connected to a second elevator 5 through a first guide conveyor belt 4, a side of the second elevator 5 away from the first elevator 3 is connected to a vibrating screen 7 through a second guide conveyor belt 6, the vibrating screen 7 is used to vibrate the coal gangue, so that some larger particles or impurities in the coal gangue remain on the vibrating screen 7, thereby ensuring that the unloading is purer, a third elevator 8 is connected to the lower part of the vibrating screen 7, and the third elevator 8 is arranged on the side of the vibrating screen 7 away from the second guide conveyor belt 6, a mounting frame 13 is arranged on one side of the top of the third elevator 8, and a mounting frame 13 is arranged on one side of the top of the third elevator 8. Two probability screens 9 are installed inside the frame 13. An inclined surface is provided on the inner side of the mounting frame 13 and on the top of the probability screen 9. The inclined surface is provided so that the gangue in the mounting frame 13 can slide toward the position of the probability screen 9. The probability screen 9 is used to vibrate the gangue. The lower part of the mounting frame 13 is connected to a plurality of yarn bins 10 through guide tubes. The vibrated gangue will enter different yarn bins 10. A bulk loader 11 is installed at the lower part of each yarn bin 10. The bulk loader 11 is provided so that the bulk loader 11 can transport the gangue mortar until it is transported to a truck. A dust collector 12 is also provided, and the dust collector 12 is provided on the outer side of the plurality of yarn bins 10. The dust collector 12 is provided so that the yarn bins 10 are dusted by the dust collector 12 during sorting.

[0030] According to the above structure, when conveying coal gangue, the raw material is conveyed to the feeding port 1, and conveyed to the first hoist 3 through the feeding port 1 through the belt conveyor 2, the first hoist 3 lifts the coal gangue, and conveys it to the second hoist 5 through the first guide conveyor belt 4, and is lifted twice by the second hoist 5, and is conveyed to the vibrating screen 7 through the second guide conveyor belt 6, and is vibrated and screened by the vibrating screen 7, and can be lifted three times by the third hoist 8, and the coal gangue mortar is evenly divided into the yarn bin 10 through the probability screen 9;

[0031] The above description is only part of the working principle of the application. The overall principle is as follows:

[0032] First, the gangue is crushed into small particles by a crusher, and then sent to a screening machine through a conveyor belt for screening to separate gangue particles of different particle sizes to meet the particle grading requirements of the mortar;

[0033] Secondly, the screened coal gangue particles are mixed with cement, water, admixtures and other mixed materials in a certain proportion to form a uniform mortar. During mixing, the type and amount of mixed materials can be adjusted according to different mortar types and performance requirements to improve the strength, durability, workability, etc. of the mortar.

[0034] Finally, the mixed mortar is sent to the dryer for drying to reduce the moisture content of the mortar to a certain level for easy storage and transportation.

[0035] A driving structure is installed between the mounting frame 13 and the probability screen 9, and the driving structure is used to drive the probability screen 9 to vibrate.

[0036] Refer to the attached Figure 3-7 , the two probability screens 9 are both slidably connected to the inside of the mounting frame 13, and the driving structure includes a fixed plate 16 fixed to the top of one side of the mounting frame 13, and the bottom of the fixed plate 16 is rotatably connected to a transmission roller 17, and an abutment plate 18 with the same number and corresponding position as the probability screen 9 is fixed to the outside of the transmission roller 17, and the two abutment plates 18 are arranged up and down and oppositely, and the abutment plate 18 includes a second arc plate 20 and a first arc plate 14, and the second arc plate 20 and the first arc plate 14 are respectively arranged on both sides, and an arc surface is arranged at the end of the first arc plate 14. Through this arrangement, when it contacts with the probability screen 9, there will be no stuck effect. When the abutment plate 18 rotates, the probability screen 9 can be abutted, so that the probability screen 9 vibrates, and a motor 15 is installed on the top of the two fixed plates 16, and a dust cover can be installed on the outside of the motor 15;

[0037] The output end of the motor 15 is vertically downward and passes through the fixed plate 16 to connect with the transmission roller 17. The side of the probability screen 9 away from the abutment plate 18 is equipped with a spring 19, and the spring 19 is fixed to the mounting frame 13.

[0038] After completing the above work, the probability screen 9 can be automatically cleaned. At this time, the motor 15 can be started, and the transmission roller 17 can be driven by the motor 15 to rotate, and the two abutment plates 18 can be driven by the transmission roller 17 to rotate. When the abutment plates 18 rotate, because the two abutment plates 18 are arranged in opposite directions, one of the abutment plates 18 contacts the probability screen 9 when it rotates, and presses the spring 19 through the probability screen 9, while the other abutment plate 18 does not contact the probability screen 9 at this time. When the transmission roller 17 drives the abutment plates 18 to continue to rotate, one of the abutment plates 18 can be rotated to not contact its corresponding probability screen 9. At this time, the probability screen 9 is reset by the spring 19, and the other abutment plate 18 rotates to contact the probability screen 9, so that the two probability screens 9 vibrate at intervals, so that the probability screen 9 can be self-cleaned.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
