Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material crushing, and in particular to a crushing and mixing device for sintered brick raw materials. Background Technology
[0002] Sintered bricks have a history of over two thousand years in my country and remain a widely used wall material. Sintered bricks are bricks made from clay, shale, coal gangue, or fly ash, formed and fired at high temperatures, and used for building load-bearing and non-load-bearing walls. Sintered bricks possess both sufficient strength and good heat and sound insulation properties, preventing condensation on indoor walls in winter. They are also inexpensive and widely used in masonry projects.
[0003] The raw materials for sintered bricks are widely available, including clay, shale, coal gangue, fly ash, silt (river and lake silt), and other solid waste. Therefore, the uniformity of mixing these raw materials significantly impacts the subsequent sintering process. Existing raw material mixing equipment has several technical drawbacks, the most significant being its inability to effectively address issues such as agglomeration in the raw materials. This results in insufficient integration of lumpy raw materials, significant variations in component distribution, and uneven brick strength after sintering. This not only affects product quality but also fails to prevent damage to the equipment caused by raw material agglomeration during mixing or pressing. Utility Model Content
[0004] In order to solve the problems in the background art, this utility model adopts the following technical solution:
[0005] A sintered brick raw material crushing and mixing device includes an upper box and a lower box that are connected vertically. Connecting discs are provided on the outer sides of the connecting surfaces of the upper and lower boxes, and adjacent connecting discs are fixedly connected by fasteners. A feed inlet is provided at the upper end of the upper box, and a flow divider is fixedly connected inside the feed inlet. A discharge outlet is provided at the bottom of the lower box. A crushing seat is fixedly connected to the inner cavity of the upper box, and a frustum-shaped cavity is provided vertically through the crushing seat. A motor is provided in the inner cavity of the lower box, and the motor is connected to the inner wall of the frustum-shaped cavity via a bracket. A crushing roller that is engaged with the frustum-shaped cavity is fixedly connected to the power end of the motor. Multiple sets of stirring rods are rotatably arranged through the outer side of the bracket.
[0006] Preferably, the bottom of the lower box cavity is provided with an inclined surface, and the bottom of the inclined surface is connected to the upper end of the discharge port.
[0007] Preferably, a frustum is fixedly connected to the center of the upper end of the diverter seat, and diverter ports are evenly arranged on the upper surface of the outer part of the frustum of the diverter seat, and the diverter ports are arranged vertically and connected to the upper end of the frustum-shaped cavity.
[0008] Preferably, the crushing roller also adopts a frustum-shaped structure design, and crushing teeth are evenly arranged on the inner wall of the frustum-shaped cavity and the outer wall of the crushing roller.
[0009] Preferably, the stirring rod has stirring blades evenly distributed on its bottom surface, and gears are fixedly connected to both the upper part of the stirring rod and the outer part of the motor power end, with the gears at the motor power end meshing with the gears at the upper end of the stirring rod.
[0010] Preferably, a switch assembly electrically connected to the motor is provided on the outside of the lower housing.
[0011] Compared with the prior art, the present invention has the following beneficial effects;
[0012] This invention achieves preliminary crushing of the feed material by setting a crushing seat in the inner cavity of the box and cooperating with the internal crushing roller, and then mixing it. This avoids the sintered blocks in the sintered brick raw material being difficult to mix and affecting product quality, and also avoids damage to the equipment caused by raw material caking during mixing or pressing.
[0013] Based on this, the present invention also provides a flow divider at the feed inlet, which can evenly disperse the incoming raw materials into the crushing seat, avoiding the concentrated falling and accumulation of raw materials that could cause blockage and affect the efficiency of crushing and even subsequent mixing.
[0014] Based on this, the box body designed in this utility model adopts a split upper and lower box design, which makes it convenient to separate the crushing seat and crushing roller for maintenance and replacement, and also facilitates the inspection and maintenance of its diversion seat and stirring structure, thereby improving the overall service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-3A sintered brick raw material crushing and mixing device includes an upper box 1 and a lower box 2 connected vertically. Connecting discs 3 are provided on the outer sides of the mating surfaces of both the upper and lower boxes 1 and 2, and adjacent connecting discs 3 are fixedly connected by fasteners. The design takes into account future maintenance and repair of the internal structure of the upper and lower boxes 1 and 2, so the connecting discs 3 can be easily removed for operation. A feed inlet 4 is provided at the top of the upper box 1, and a diverter seat 6 is fixedly connected inside the feed inlet 4. The lower box 2 is located at the bottom... The upper chamber 1 is equipped with a discharge port 5. A crushing seat 7 is fixedly connected to the inner cavity of the upper chamber 1. A frustum-shaped cavity 8 is provided through the upper and lower parts of the crushing seat 7. A motor 9 is provided in the inner cavity of the lower chamber 2. The motor 9 is connected to the inner wall of the frustum-shaped cavity 8 through a bracket 10. A crushing roller 11 is fixedly connected to the power end of the motor 9 and is snapped into the frustum-shaped cavity 8. The crushing roller 11 also adopts a frustum-shaped structure design. Crushing teeth are evenly provided on the inner wall of the frustum-shaped cavity 8 and the outer wall of the crushing roller 11. Multiple sets of stirring rods 12 are rotatably provided on the outer side of the bracket 10. The upper center of the diversion seat 6 is fixedly connected to a frustum 601. The upper surface of the diversion seat 6 on the outer part of the frustum 601 is evenly provided with diversion ports 602. The diversion ports 602 are arranged vertically and connected to the upper end of the frustum-shaped cavity 8. The stirring rod 12 is evenly provided with stirring blades 1201 on the bottom surface of the support 10. Gears 1202 are fixedly connected to the upper part of the stirring rod 12 on the support 10 and the outer part of the power end of the motor 9. The gears 1202 on the power end of the motor 9 and the gears 1202 on the upper end of the stirring rod 12 mesh with each other. A switch group 13 electrically connected to the motor 9 is provided on the outer side of the lower housing 2.
[0024] Based on the above structural design, when using this device, the operator pours the raw material of sintered bricks into the feed port 4, passes through the diversion seat 6, and slides down from the inclined surface of the truncated cone 601 at the upper end of the diversion seat 6 and is evenly dispersed. It flows through the diversion port 602 and then evenly enters the truncated cone cavity 8, avoiding accumulation in one place and causing blockage. The raw material passes through the gap between the crushing roller 11 and the inner wall of the truncated cone cavity 8. When the switch group 13 starts the motor 9 and drives the crushing roller 11 to rotate, the crushing roller 11 and the crushing teeth on the inner wall of the truncated cone cavity 8 crush and grind the flowing raw material, thereby crushing the sintered blocks and mixing them. The crushed raw material falls directly into the lower box 2. At the same time as the motor 9 rotates, the outer gear 1202 meshes and drives the stirring rod 12 to rotate. The stirring blades 1201 on the outer side of the stirring rod 12 fully mix and stir the raw material in the inner cavity of the lower box 1, and then it is discharged from the discharge port 5.
[0025] When replenishment is needed, gear 1202 is always located at the bottom of crushing roller 11, and raw materials will not fall directly onto the top of gear 1202 and affect the normal rotation of the gear. Subsequently, the upper box 1 and lower box 2 can be disassembled periodically to clean and maintain the internal structure, including gear 1202.
[0026] The lower chamber 2 has an inclined surface at the bottom of its inner cavity, and the bottom of the inclined surface is connected to the upper end of the discharge port 5. It should also be noted that the bottom of the discharge port 5 is threaded with a sealing plug. During the mixing process, the sealing plug will block the discharge port 5. After the mixing is completed, the sealing plug will be opened and the raw material of the sintered brick can slide down the inclined surface and be discharged through the discharge port 5 for collection.
[0027] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
