Description

Technical Field

[0001] This utility model relates to the field of coal gangue processing, and in particular to a coal gangue aggregate proportioning and mixing device. Background Technology

[0002] The main function of coal gangue aggregate mixing is to uniformly mix the aggregate formed after crushing and screening coal gangue with other cementing materials (such as cement, fly ash, etc.) and water to prepare stable and usable building materials (such as concrete, blocks, or roadbed materials). The mixing process can improve the particle size distribution of coal gangue aggregate, enhance its bonding force with cementing materials, and improve the strength, durability, and volume stability of the finished products.

[0003] Patent CN210332820U discloses a high-efficiency coal gangue powder mixing device, including a base plate. A first housing is located at the center of the upper surface of the base plate. A screening mechanism is located inside the first housing. A mixing tank is located on the left side of the first housing. Support rods are fixedly connected to the four corners of the lower surface of the first housing, and these support rods are fixedly connected to the base plate. A feed hopper is fixedly connected to the top of the first housing. This high-efficiency coal gangue powder mixing device, through the cooperation between the base plate, the first housing, the crushing roller, the screening mechanism, the second housing, the feeding device, and the mixing tank, eliminates the need for unnecessary transportation of the crushed coal gangue. Through the cooperation between the tank, the motor, the first gear, the second gear, the uprights, and the mixing rods, the two sets of uprights inside the tank rotate in opposite directions, thereby enhancing the mixing efficiency of the coal gangue powder inside the tank.

[0004] While existing technologies can efficiently mix and crush certain amounts of coal gangue aggregate using relative rotation, they still have several drawbacks. For example, current coal gangue aggregate crushing and mixing processes cannot accurately classify the aggregates, resulting in simultaneous mixing and crushing of particles of varying sizes, significantly reducing crushing efficiency, easily damaging the machine, and wasting a large amount of energy. Therefore, we propose a coal gangue aggregate proportioning and mixing device that solves these problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a coal gangue aggregate proportioning and mixing device.

[0006] The technical solution of this utility model: A coal gangue aggregate proportioning and mixing device includes a box body, a feeding trough, a screen plate, and a bidirectional motor. The upper end of the box body is provided with a processing trough one, a processing trough two is provided on one side of the processing trough one, and a processing trough three is provided on one side of the processing trough two. A feeding trough is provided above the processing trough one. An inclined screen plate is fixed inside the feeding trough. The lower ends of the processing trough one, processing trough two, and processing trough three are respectively provided with guide wheels one, guide wheels two, and guide wheels three. A mounting frame is fixed at the lower end of the processing trough two. A bidirectional motor is fixed inside the mounting frame. The upper output shaft of the bidirectional motor is fixedly connected to the rotation center of the lower end of the guide wheel two. A stirring frame is provided inside the box body. The lower output shaft of the bidirectional motor is fixedly connected to the rotation center of the upper end of the stirring frame.

[0007] When using this device, the material to be processed can be poured directly into the feed inlet. Since the material particles are of uneven size, the vibrating motor drives the screen plate to separate the three sizes of material, which then enter the lower processing tanks one, two, and three. These three tanks then utilize built-in stirring racks with different spiral distances to grind and pulverize the material. The processed material then enters the housing through the transmission channel to participate in the overall mixing process. This device can simultaneously drive three stirring racks and frames using a single motor, saving energy and achieving targeted screening and grinding effects. It reduces abnormal noises and jamming caused by unsuitable sizes, making it highly practical in the field of coal gangue aggregate proportioning and mixing.

[0008] Preferably, stirring rack 1, stirring rack 2, and stirring rack 3 are rotatably installed inside processing tank 1, processing tank 2, and processing tank 3, respectively. Stirring rack 1, stirring rack 2, and stirring rack 3 rotate coaxially with the upper ends of guide wheels 1, guide wheels 2, and guide wheels 3, respectively. Processing tank 1, processing tank 2, and processing tank 3 are fixed by a fixing frame. By setting stirring rack 1, stirring rack 2, and stirring rack 3 inside processing tank 1, processing tank 2, and processing tank 3, and rotating coaxially with guide wheels 1, guide wheels 2, and guide wheels 3, it is ensured that each stirring rack operates independently, improving grinding accuracy and efficiency, and avoiding uneven crushing caused by mixing materials of different sizes. Belt 1 is provided between guide wheels 1 and guide wheels 2, and belt 2 is provided between guide wheels 2 and guide wheels 3. Belt 1 and belt 2 are used for the synchronous rotation of guide wheels 1, guide wheels 2, and guide wheels 3.

[0009] Preferably, the first, second, and third mixing racks are spiral blade designs with gradually increasing pitch. The inner walls of the first, second, and third processing tanks are all equipped with fins. These fins work in conjunction with the spiral blades to grind the materials. The spiral blade design of the mixing racks, combined with the fins on the inner walls of the processing tanks, allows for the application of varying degrees of shearing and grinding forces to materials of different particle sizes, optimizing the pulverization effect. This structural design improves the uniformity of material grinding and reduces energy consumption.

[0010] Preferably, a bracket is fixed to the lower end of the housing, and a base is fixed to the lower end of the bracket. The bracket and base at the lower end of the housing enhance the stability of the overall structure, reduce vibration and displacement during equipment operation, ensure the reliability of long-term continuous operation, and facilitate the installation and fixation of the equipment.

[0011] Preferably, a controller is provided on one side of the outer wall of the box, a discharge port is provided on the lower side of the box, and a feed port is provided on the upper side of the feed trough. The controller on the outer wall of the box facilitates the operator to adjust the equipment operating parameters, improves the degree of automation, and the reasonable layout of the feed port and discharge port optimizes the material conveying process, reduces manual intervention, and improves production efficiency.

[0012] Preferably, the first, second, and third processing tanks are connected to the housing via a transmission channel. The transmission channel is rigidly designed, and the connection between the processing tanks and the housing is made by a rigid transmission channel to ensure that the materials are not easily blocked or leaked during the transfer process, thereby improving the conveying efficiency and enhancing the overall structural stability.

[0013] Preferably, the sieve plate has through holes inside, and the spacing between the through holes gradually increases from top to bottom. A vibration motor is fixed at the lower end of the sieve plate. The design of the through holes gradually increasing in spacing from top to bottom, together with the vibration motor, can efficiently screen materials of different particle sizes, improve screening accuracy and speed, reduce material accumulation, and ensure the smooth progress of subsequent grinding processes.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, by setting up processing tank one, processing tank two and processing tank three, and in conjunction with the vibrating screening function of the sieve plate, can efficiently separate materials of different sizes and perform targeted grinding respectively, thereby improving the crushing efficiency.

[0016] Second, based on the first beneficial effect, the bidirectional motor drives three mixing racks and mixing frames simultaneously, reducing energy consumption and lowering equipment operating costs. In addition, this design can effectively avoid material jamming and abnormal noise, improve equipment stability and service life, and is particularly suitable for the proportioning and mixing of coal gangue aggregates, with high practicality and economy.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
