Description

Technical Field

[0001] The utility model relates to the technical field of non - fired brick processing, in particular to an automatic feeding and stirring device for non - fired brick processing. Background Technique

[0002] Non - fired bricks are building materials made from a variety of raw materials such as fly ash, coal cinder, coal gangue, tailings slag, chemical slag, natural sand, and coastal mud. After these raw materials are mixed through appropriate processes and ratios, they are manufactured by pressing or extrusion molding. Because a large amount of carbon dioxide emissions are not generated during the manufacturing process, they have the characteristics of environmental protection and energy conservation, and have gradually become an important choice in modern construction projects.

[0003] During the processing of non - fired bricks, an automatic feeding and stirring device is usually required to stir the raw materials. The common method is to automatically feed the materials through a spiral knife. Since the sizes of the raw materials are different and they are all stacked together, it is impossible to effectively screen out larger materials during the feeding process, which may affect the uniformity and quality of the materials inside the stirring tank, and further affect the processing effect and product quality of the final non - fired bricks. For this reason, we provide an automatic feeding and stirring device for non - fired brick processing. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1

[0029] As shown in the attached Figure 1 to the attached Figure 5 figures: An automatic feeding and stirring device for non-burned brick processing includes: a stirring box 1 and a screw conveyor 2 arranged outside the stirring box 1. The top end of the screw conveyor 2 can directly convey materials into the screening box 301. The upper surface of the stirring box 1 is fixedly communicated with a water injection pipe 5, and the bottom surface of the stirring box 1 is fixedly communicated with a discharge pipe 6. Water can be added into the stirring box 1 by using the water injection pipe 5, and the stirred materials can be discharged from the inside of the stirring box 1 through the discharge pipe 6.

[0030] The screening assembly 3 is arranged above the mixing box 1, and includes a screening box 301 connected to the top of the screw conveyor 2, a discharge trough 302 opened in the middle of one side of the screening box 301, a screening structure arranged inside the screening box 301, and a top pulling structure installed on one side of the screening box 301 for reciprocating the screening structure.

[0031] The top pulling structure of the screening assembly 3 includes a motor 306 installed on one side of the screening box 301, and the output end of the motor 306 is fixedly connected to a half gear 307, and the outside of the half gear 307 is meshed with a frame-shaped tooth plate 308, and two groups of symmetrical teeth are installed on the inside of the frame-shaped tooth plate 308. The half gear 307 is adapted to the teeth on both sides. When the half gear 307 is disengaged from the teeth on one side of the frame-shaped tooth plate 308, it will promptly engage with the teeth on the other side of the frame-shaped tooth plate 308, thereby avoiding the situation where the half gear 307 and the frame-shaped tooth plate 308 are disengaged.

[0032] The front and back sides of the frame-shaped toothed plate 308 are respectively fixedly connected to the ends of the two rotating shafts 305 that are close to each other. When the motor 306 drives the half gear 307 to rotate, the frame-shaped toothed plate 308 will perform reciprocating lifting motion, and the frame-shaped toothed plate 308 can drive the rotating shaft 305 to rise and fall when it moves.

[0033] The screening assembly 3 includes a screening plate 303 hinged to the inner wall of the screening box 301, and two support plates 304 are hinged to the bottom surface of the screening plate 303. The two support plates 304 are rotatably connected to the side surfaces close to each other with a rotating shaft 305. When the rotating shaft 305 is raised or lowered, the support plates 304 will be pushed, and the support plates 304 will be deflected and push the screening plate 303, and the screening plate 303 will screen out the large block materials and discharge them from the discharge trough 302.

[0034] A positioning plate 309 is fixedly connected to one side of the screening box 301, and two positioning rods 310 are slidably connected to the upper surface of the positioning plate 309. The top of each positioning rod 310 is connected to the bottom surface of the frame-shaped tooth plate 308. The frame-shaped tooth plate 308 can be positioned by utilizing the cooperation between the positioning rod 310 and the positioning plate 309, thereby preventing deviation between the frame-shaped tooth plate 308 and the half gear 307.

[0035] The bottom surface of the screening box 301 is fixedly connected with two feed pipes 311, and the bottom end of each feed pipe 311 passes through the mixing box 1 and extends into the inside of the mixing box 1. The feed pipe 311 can be used to transport the material that falls to the bottom of the screening box 301 to the inside of the mixing box 1 for mixing.

[0036] Example 2

[0037] On the basis of Embodiment 1, in order to collect the dust generated during screening, a dust collection assembly 4 is provided above the screening box 301 for removing dust during screening of materials. The dust collection assembly 4 includes an airtight frame 401 disposed above the screening box 301. A blower 402 is installed on the upper surface of the airtight frame 401. The airtight frame 401 can seal the top of the screening box 301, and the blower 402 can suck the dust when it works.

[0038] A dusttight cover 403 is fixedly connected to the upper surface of the airtight frame 401. The top of the dusttight cover 403 is fixedly connected and communicated with a dust discharge pipe 404. The cooperation of the dusttight cover 403 and the dust discharge pipe 404 can guide the sucked dust, facilitating the staff to collect the dust.

[0039] Plug rods 405 are fixedly connected to both the front and the back of the airtight frame 401. An insertion cylinder 406 is inserted outside each plug rod 405. The bottom end of each insertion cylinder 406 is connected to the upper surface of the mixing tank 1. The cooperation of the insertion cylinder 406 and the plug rod 405 can fix the airtight frame 401 stably above the screening box 301, which is beneficial to sucking the dust.

[0040] Working principle: When in use, first start the motor 306 and the blower 402, and then control the screw conveyor 2 to perform feeding and loading work. The screw conveyor 2 will convey the materials to the sieve plate 303. At the same time, the motor 306 will drive the half gear 307 to rotate. When the half gear 307 meshes and rotates with the tooth teeth on one side of the frame-shaped tooth plate 308, the frame-shaped tooth plate 308 will rise. At the same time, the rotating shaft 305 will also rise and rotate, and the support plate 304 will deflect to push the sieve plate 303. When the half gear 307 rotates to mesh with the tooth teeth on the other side of the frame-shaped tooth plate 308, the frame-shaped tooth plate 308 will descend, and at the same time the sieve plate 303 will reset. Such reciprocating motion can screen out the large pieces of materials in the materials and discharge them from the discharge chute 302. And the blower 402 can suck and discharge the screened dust, thus ensuring the uniformity of the materials inside the mixing tank 1 and ensuring the processing effect and product quality of the non-burning bricks.
