[0025] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0026] As Figure 1 - Figure 2 shown, this embodiment provides an artificial aggregate production equipment 100, including a material mixing device 1, a granulation device, a conveying device, a polishing device and a controller 9. The granulation device includes a propulsion extruder 2, a cutting machine 3 and a first sensor.

[0027] The material is pushed out along with the extrusion machine 2, and a cylindrical material is formed through the extrusion head of the extrusion machine 2. A plurality of cylindrical holes are distributed on the extrusion head. In this embodiment, different extrusion heads can be replaced to adjust the diameter of the cylindrical material.

[0028] After the front end of the cylindrical material extruded from the discharge port of the extrusion machine 2 touches the sensing range of the first sensor, a signal is transmitted to the controller 9, and the controller 9 controls the cutting machine 3 to perform cutting, thereby realizing precise control of the height of the cylindrical material, and cylindrical materials with different heights can be prepared according to actual needs.

[0029] This embodiment also includes two overlimit alarm devices 7. One overlimit alarm device 7 is arranged at one end of the particle size separation conveyor 4 close to the extrusion machine 2, and the other overlimit alarm device 7 is arranged at one end of the particle size separation conveyor 4 close to the polishing device. Both overlimit alarm devices 7 are connected to the controller 9.

[0030] Specifically, the overlimit alarm device 7 includes an inverted U-shaped bracket 31, a second sensor, and an alarm. The inverted U-shaped bracket 31 covers the particle size separation conveyor 4, and both the second sensor and the alarm are arranged on the inverted U-shaped bracket 31 and are both connected to the controller 9.

[0031] The inverted U-shaped bracket 31 in this embodiment includes a horizontal rod and two vertical rods respectively arranged at the lower parts of both ends of the horizontal rod. The lower ends of the vertical rods are used to contact the ground. The second sensor is arranged on one side of a vertical rod close to the particle size separation conveyor 4, and the alarm is arranged on the horizontal rod or the vertical rod.

[0032] When the second sensor senses the situation of material accumulation or material scattering, a signal is transmitted to the controller 9. The controller 9 controls the alarm to emit an alarm signal and simultaneously controls the extrusion machine 2 and the particle size separation conveyor 4 to stop working.

[0033] In this specific embodiment, both the first sensor and the second sensor are photoelectric sensors. The material stirring device 1 is a mortar mixer, and the extrusion machine 2 is a twin-screw extrusion machine. Specifically, the material stirring device 1 uses a 20L mortar mixer.

[0034] The cutting machine 3 in this embodiment is a pneumatic cutting machine 3. The pneumatic cutting machine 3 includes a bracket 31, a cylinder 32, and a cutting head 33. The bracket 31 is arranged on the upper part of the extrusion machine 2. The cylinder 32 is arranged on the bracket 31.

[0035] Specifically, the blower is arranged on one side of the particle size separation conveyor 4, and the blowing direction of the blower is perpendicular to the conveying direction of the particle size separation conveyor 4.

[0036] The dryer in this embodiment includes a heating sheet 5 and a support mechanism. The heating sheet 5 is located in the annular space of the conveyor belt of the particle size separation conveyor 4. There is a gap between the heating sheet 5 and the conveyor belt of the particle size separation conveyor 4. The upper end of the support mechanism is connected to the heating sheet 5, and the heating sheet 5 is connected to the controller 9.

[0037] Specifically, the support mechanism includes a plurality of support components arranged in sequence along the conveying direction of the particle size separation conveyor 4. Each support component includes two support columns 6 respectively arranged on the front and rear sides of the conveyor belt of the particle size separation conveyor 4. The upper end of the support column 6 is connected to the heating sheet 5, and the lower end of the support column 6 is used to contact the ground.

[0038] The polishing device in this embodiment includes a disk granulator 8 and a powder sprinkler. The disk granulator 8 is arranged on one side of the discharge end of the particle size separation conveyor 4, and the powder sprinkler is arranged on the upper end of the disk granulator 8. Both the disk granulator 8 and the powder sprinkler are connected to the controller 9. In this embodiment, a 60 cm disk granulator is used.

[0039] In this specific embodiment, the distance between the bottom end of the discharge port of the extrusion machine 2 and the upper surface of the conveyor belt of the particle size separation conveyor 4 is 15 cm, and the center of the disk of the disk granulator 8 is flush with the upper surface of the conveyor belt of the particle size separation conveyor 4.

[0040] The specific use process is as follows:

[0041] Step 1: Material pretreatment

[0042] Mix the powdered solid waste and mineral admixture according to the mixing ratio obtained from the previous tests, add a mixed solution such as an additive (the best solid waste mixing ratio design and the best plastic material state of the mixture were obtained through previous tests), and prepare the raw materials into a material in the best plastic state through the material stirring device 1.

[0043] It can be seen that in Step 1, the raw materials in the dry powder state can be mixed to form a semi-dry mortar state that can be extruded.

[0044] Step 2: Material granulation treatment

[0045] Put the material stirred by the material stirring device 1 into the feed hopper of the extrusion machine 2. Start the extrusion machine 2, and the speed can be adjusted according to the discharge state. The extrusion machine 2 pushes the stirred material into the forming die and extrudes it through the extrusion head. After the front end of the extruded cylindrical material touches the sensing range of the first sensor, a signal is transmitted to the controller 9, and the controller 9 controls the cutting machine 3 to cut to obtain the prototype aggregate.

[0046] It can be seen that in Step 2, the material can be cut into an ideal size to obtain the prototype aggregate.

[0047] Step 3: Material drying and conveying process

[0048] The prototype aggregate enters the particle size separation conveyor 4. At this time, the material has a relatively high viscosity, with various particle sizes and mutual adhesion. The conveying device can perform blowing and drying as well as particle size screening. At this time, most of the materials are cylindrical particles with many edges and corners.

[0049] It can be seen that Step 3 is to prevent the prototype aggregates from sticking to each other and maintain an ideal aggregate state.

[0050] Step 4: Polishing and shaping process

[0051] The prototype aggregates with the same particle size enter the disk granulator 8 through the conveying device. The equipment in this area can polish and dry the prototype aggregates. By adding different drying powders through the powder sprinkler, material particles with different roughness can be obtained, and the aggregates with edges and corners are ground into a smooth ellipsoidal state, which is the artificial aggregate to be produced. An opening is provided at the lower part of the disk granulator 8 in this area, making it convenient to collect the artificial aggregates.

[0052] It can be seen that Step 4 can polish and grind the prototype aggregates to obtain the artificial aggregates in the final form.

[0053] It can be known from this that the artificial aggregate production equipment 100 in this embodiment is divided into four different functional areas, which can operate independently of each other without interference. The material is cut into an ideal size by the cooperation of the first sensing component and the cutting machine 3, and then the particle size of the obtained artificial aggregates can be accurately controlled through the screening of the particle size separation conveyor 4, making the particle shape of the artificial aggregates uniform. The roughness of the artificial aggregates is controlled according to actual needs through the polishing device to meet the actual engineering use. At the same time, no binder is required, avoiding the influence of the bonding effect of the binder on the strength of the artificial aggregates and saving the cost of the binder. The artificial aggregate production equipment 100 can realize the automated production of artificial aggregates, and regulate each process from raw material preparation, processing to artificial aggregate preparation and then to artificial aggregate collection, making the production of artificial aggregates more efficient.

[0054] In this specification, specific examples are used to elaborate on the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
