Description

Technical Field

[0001] This utility model belongs to the technical field of construction waste treatment equipment, specifically a multi-stage sorting construction waste aggregate purification machine. Background Technology

[0002] Currently, existing construction waste processing equipment has many shortcomings in aggregate purification. For example, some equipment has too few sorting stages, making it impossible to finely grade the aggregates in construction waste, resulting in inconsistent quality of purified aggregates that fails to meet the production requirements of high-quality building materials. In summary, existing construction waste aggregate purification equipment has deficiencies in sorting effect, impurity removal capacity, operating efficiency, and stability. Moreover, these sorting machines with fewer sorting stages are generally arranged in horizontal series, which leads to high operating costs for multiple air separators. Summary of the Invention

[0003] Existing construction waste aggregate purification equipment suffers from deficiencies in sorting effect, impurity removal capacity, operating efficiency, and stability. There is an urgent need for a new type of equipment capable of multi-stage sorting, efficient purification of construction waste aggregate, stable operation, and low energy consumption. The purpose of this invention is to overcome these technical problems and provide a multi-stage construction waste aggregate purification machine. During the step-by-step air separation process, the material, through contact with the separating rollers and the action of wind force, achieves step-by-step separation of light and heavy materials, thereby purifying the aggregate in the construction waste.

[0004] The objective of this utility model is achieved through the following technical solution: A multi-stage construction waste aggregate refining machine includes a settling chamber. The discharge port of a feeding conveyor extends into the inlet of the settling chamber. A pre-selection fan and a multi-stage separation fan are arranged from top to bottom on the left side of the settling chamber. A material spreading disc, a dispersing roller, and a multi-stage material separation adjusting device are arranged sequentially from top to bottom on the right side of the settling chamber. The material spreading disc is positioned below the inlet, and a dispersing roller support is positioned below the material spreading disc. The dispersing roller is mounted on the dispersing roller support and is driven to rotate by a drive device installed outside the settling chamber. The pre-selection fan is connected to a pre-selection fan nozzle, and the outlet of the pre-selection fan nozzle is connected to the top of the dispersing roller. Correspondingly, each stage of the sorting fan corresponds to a separation adjustment device. A recessed area is set between adjacent stages of the sorting fan. The separation adjustment device is installed on the adjustment frame, which extends into the recessed area. From top to bottom, each stage of the fan and the corresponding adjustment frame form a serpentine material channel. A finished product outlet is set at the bottom of the settling chamber. A light material collection chamber is set on the right side of the settling chamber. Each stage of the settling chamber at the top of the separation adjustment device is equipped with a corresponding light material flow port. Each stage of the light material flow port can connect the settling chamber and the light material collection chamber. A dust collection port is set at the top of the light material collection chamber, and a light material outlet is set at the bottom of the light material collection chamber.

[0005] The aforementioned multi-stage construction waste aggregate purification machine includes a multi-stage sorting fan consisting of a second-stage sorting fan, a third-stage sorting fan, and a fourth-stage sorting fan, arranged from top to bottom. Each stage of the sorting fan is equipped with a fan nozzle that extends into the settling chamber, and the air outlet of the fan nozzle corresponds to the top of the material separation and adjustment device of the corresponding stage.

[0006] In the above-mentioned multi-stage construction waste aggregate purification machine, the wind pressure and flow rate of the secondary, tertiary and quaternary separation fans increase progressively, and the wind pressure and flow rate of the pre-selection fan are greater than those of the secondary separation fan.

[0007] The above-mentioned multi-stage sorting construction waste aggregate purification machine has a spray dust suppression device installed at the top of the light material collection chamber.

[0008] The aforementioned multi-stage sorting construction waste aggregate purification machine has multiple parallel grids installed on the top of the light material collection chamber between the dust collection port and the spray dust suppression device.

[0009] The aforementioned multi-stage sorting construction waste aggregate purification machine has a first and a second grid installed parallel to each other at the top of the light material collection chamber between the dust collection port and the spray dust suppression device.

[0010] The aforementioned multi-stage sorting construction waste aggregate purification machine includes a material separation and adjustment device comprising an arc-shaped frame installed on both sides of the adjustment frame, with several adjustment holes provided on the arc-shaped frame, and the two side walls of the material separation plate being bolted into the adjustment holes of the two arc-shaped frames.

[0011] Compared with the prior art, the present invention has the following technical effects: This invention reduces the number of air separators connected in series laterally, enabling the step-by-step separation of substances with different densities, volumes, and specific surface areas in construction waste aggregates on a single machine. This process ultimately purifies the construction waste aggregates, reduces investment costs, and increases the economic benefits for enterprises. The pulse dust collector equipped with the multi-stage separation construction waste aggregate purification machine effectively collects lightweight impurities and dust, preventing environmental pollution. The efficient operation of the entire system improves the resource utilization rate of construction waste, reduces the negative environmental impact of construction waste, and meets the requirements of sustainable development.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] Because construction waste comes from multiple sources and is extremely complex, containing various types of decoration and renovation waste, as well as household waste, large items can be sorted manually or by robots during the recycling process. However, thoroughly pre-separating materials such as plastic bags, plastic sheets, cardboard boxes, old clothes and fabrics, thin steel bars, aluminum alloy strips, sponges, foam, asbestos cloth, asbestos boards, and weeds mixed in with the construction waste is difficult and physically demanding. Therefore, these materials must first be separated and sorted before undergoing further recycling processes to obtain high-quality, high-purity building aggregates.

[0016] This utility model is designed to solve the above-mentioned problems by providing a multi-stage sorting and purification machine for construction waste aggregates, such as... Figure 1 As shown, the purification machine includes a settling chamber. The discharge port of the feed conveyor 1 extends into the feed inlet of the settling chamber. From top to bottom, a pre-selection fan 2 and a multi-stage separation fan are arranged on the left side of the settling chamber. From top to bottom, a material spreading disc 12, a dispersing roller 13, and a multi-stage material separation adjusting device 14 are arranged on the right side of the settling chamber. The material spreading disc is located below the feed inlet, and a dispersing roller support is located below the material spreading disc. The dispersing roller is mounted on the dispersing roller support and is driven to rotate by a drive device installed outside the settling chamber. The pre-selection fan 2 is connected to a pre-selection fan nozzle, and the outlet of the pre-selection fan nozzle corresponds to the top of the dispersing roller. Each stage of separation fan... Each machine corresponds to a separation and adjustment device. A recessed area 16 is provided between adjacent separation fans. The separation and adjustment device is installed on the adjustment frame 15, which extends into the recessed area. From top to bottom, each fan and the corresponding adjustment frame form a serpentine material channel. A finished product outlet 17 is provided at the bottom of the settling chamber. A light material collection chamber 10 is provided on the right side of the settling chamber. Each settling chamber at the top of each separation and adjustment device is provided with a corresponding light material flow port. Each light material flow port can connect the settling chamber and the light material collection chamber. A dust collection port 6 is provided at the top of the light material collection chamber, and a light material outlet 11 is provided at the bottom of the light material collection chamber.

[0017] The feeding conveyor 1 of this utility model brings the construction waste materials that need to be sorted into the settling chamber of the purification machine. Using the air force blown by the vertically set multi-stage high-pressure machine, light and heavy materials with different diameters, densities and volumes in the mixed materials are separated. The heavy materials fall from the finished product outlet, and the light materials enter the light material collection chamber through the light material outlets of each stage, and then flow out from the light material outlet.

[0018] The material spreading disc 12 of this utility model is a buffer and dispersing disc on the purification machine used to receive a large amount of material entering from the feeding conveyor 1. It must withstand the high impact force of the material and requires the use of high-strength, high-wear-resistant steel plates. The dispersing roller 13 is used on the purification machine to further disperse the large amount of material entering, facilitating subsequent air separation. The light material collection chamber 10 is a container for collecting light materials and dust blown in from various air ducts of the purification machine. It is a sealed chamber with environmental protection and collection functions. The light material outlet 11 is the outlet of the light material collection chamber 10 on the purification machine. Various impurities in the various construction waste aggregates collected from the light material collection chamber 10 are recycled through it.

[0019] The dust collection port 6 of this utility model is a dust collector connection device installed on the purification machine. It is softly connected to the dust collector duct through a flexible and tough canvas for environmentally friendly dust removal.

[0020] The light material collection chamber 10 of this invention is a container for collecting light materials and dust blown into various air ducts of the purification machine. It is a sealed chamber that serves both environmental protection and collection purposes.

[0021] The pre-selection fan 2 of this invention is a blower installed on the purification machine and controlled by a frequency converter. Depending on the fan power and the frequency converter's adjustment, it generates different levels of airflow to separate light materials of different sizes and collect dust. The nozzle of the pre-selection fan 2 is where the strong airflow from the high-pressure blower is blown into the settling chamber, causing light and heavy materials of different diameters, densities, and volumes brought in by the feed conveyor 1 to be separated onto the dispersing roller 13. The pre-selection fan 2 handles the largest amount of material, and its air pressure and flow rate are higher than those of the subsequent sorting fans.

[0022] The multi-stage sorting construction waste aggregate purification machine of this utility model includes a multi-stage sorting fan comprising a secondary sorting fan 3, a tertiary sorting fan 4, and a quaternary sorting fan 5, arranged from top to bottom. Each stage of the sorting fan is equipped with a fan nozzle extending into the settling chamber, and the outlet of the fan nozzle corresponds to the top of the material separation adjustment device of the corresponding stage. Compared to the tertiary sorting fan 4, the secondary sorting fan 3 and the quaternary sorting fan 5 have progressively increased air pressure and flow rate requirements to gradually separate large impurities in the aggregate that are moving downwards by gravity.

[0023] The multi-stage sorting construction waste aggregate purification machine of this utility model has a spray dust suppression device 9 installed at the top of the light material collection chamber. The spray dust suppression device is a device used to suppress dust. It uses an external water pipe to spray part of the dust to cause large and medium-sized dust particles to settle downwards, reducing the pressure on the dust collector.

[0024] The multi-stage sorting construction waste aggregate purification machine of this utility model has multiple grids arranged in parallel at the top of the light material collection chamber between the dust collection port and the spray dust suppression device.

[0025] The multi-stage sorting construction waste aggregate purification machine of this utility model has a first grid 7 and a second grid 8 installed parallel to each other at the top of the light material collection chamber between the dust collection port and the spray dust suppression device. The first grid 8 is a fine and light material blocking grid installed in the dust collection chamber of the purification machine. Its main function is to prevent light material fragments of different sizes brought in by the high-pressure airflow from entering the dust collector and clogging the dust collector duct. The second grid 7 is a fine and light material blocking grid installed in the dust collection chamber of the purification machine. Its main function is to further prevent light material fragments of different sizes brought in by the high-pressure airflow from entering the dust collector and clogging the dust collector duct.

[0026] The multi-stage sorting construction waste aggregate purification machine of this utility model includes a material separation and adjustment device comprising an arc-shaped frame installed on both sides of the adjustment frame 15, with several adjustment holes provided on the arc-shaped frame. The two side walls of the material separation plate are bolted into the adjustment holes of the two arc-shaped frames. By adjusting the different adjustment holes on the corresponding arc-shaped frames, the tilt angle of the material separation plate can be adjusted. The direction adjustment can control the size of the light material discharge channel. Its function is to facilitate the debugging of the machine and adapt it to the separation of different sizes and proportions of impurities in different construction waste aggregates.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
