Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel aggregate processing, in particular to a dust removal method for a dry production system of building aggregates. Background Art

[0002] The dry production process of the sand and gravel aggregate processing system has a large amount of dust accumulation during the transportation of sand and gravel aggregates, which affects the operating efficiency of the belt conveyor and the transfer station, the on-site environment, and the quality of sand and gravel aggregates. At present, the dust accumulation in the transfer station is generally cleaned regularly by manual and mechanical means, which has low cleaning efficiency and high costs. The dust waste accumulation problem at the transfer station is cleaned by a specially developed and designed dust waste ash conveying and aggregation device. This method can, in most cases, ensure that the dust waste accumulation problem at the transfer station and the powder content of sand and gravel aggregates are controlled within the qualified standards.

[0003] However, in special circumstances, the dust waste recovery device fails to recycle and process in time, and the dust waste enters the finished product yard along with the sand and gravel aggregates, directly enters the export link, and is scattered in the processing system, which will cause the dust content of the aggregates to be too high, pollute the aggregates, pollute the processing environment, reduce the quality of the finished sand and gravel aggregates, and the quality of the sand and gravel aggregates directly exported is also difficult to guarantee.

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] Please refer to the attached Figure 1 The embodiment of the present invention provides a dust removal device for a dry production system of building aggregates, comprising:

[0032] Support frame, used to install other components;

[0033] Specifically, the device includes a sturdy support frame for carrying and fixing the various components of the entire dust removal device to ensure the stable operation of the system during the dry production process of sand and gravel aggregates. The design of the support frame should take into account the structural layout of the system and use materials of sufficient strength (such as carbon steel or stainless steel) to ensure that it can bear the weight of the conveyor belt and the recovery device during operation. The support frame is welded or bolted to firmly install the dust waste recovery hopper 3, the dust waste guide pipe 4 and the dust waste recovery storage tank 5 and other components at the transfer position of the conveyor belt system to ensure that these components maintain the correct relative position during the transportation process to prevent the components from being misplaced or loosened due to vibration or load changes.

[0034] The first conveyor belt 1 and the second conveyor belt 2 are used to convey dust collected in the construction aggregate dry production system;

[0035] Specifically, it is used to transport dust waste collected during the production process. The first conveyor belt 1 is installed at the initial position of the system, and is responsible for transporting the generated dust from the source of the production line to the transfer station. The conveyor belt is usually made of wear-resistant materials to withstand long-term wear of sand and gravel aggregates and dust. The second conveyor belt 2 is connected to the first conveyor belt 1 and is located in the next link of the production system. It continues to transmit the dust collected from the first conveyor belt 1 and transmits the dust to the entrance of the dust waste recovery hopper 3. The two conveyor belts are mechanically connected to ensure that the material can be smoothly transferred from the first conveyor belt 1 to the second conveyor belt to prevent dust from scattering or overflowing during the transfer process. The speed and angle design of the conveyor belt need to be optimized according to the amount of dust and the transmission distance to ensure the efficient operation of the system.

[0036] The dust waste recovery hopper 3 is installed on one side of the support frame and is arranged at the head of the first conveyor belt 1 and the second conveyor belt 2 to collect dust waste; the dust waste recovery hopper 3 is designed according to the repose angles of the first conveyor belt 1 and the second conveyor belt 2, and the angle range is 30°-45°.

[0037] Specifically, the dust waste recovery hopper 3 is a key component for collecting dust waste generated during the dry production of sand and gravel aggregates. The dust waste recovery hopper 3 is installed on one side of the support frame and is set at the head position of the first conveyor belt 1 and the second conveyor belt 2 to ensure that the dust waste scattered during the material transfer above the conveyor belt can be effectively collected. The design of the dust waste recovery hopper 3 needs to be adjusted according to the repose angle of the first conveyor belt 1 and the second conveyor belt 2 to ensure that the angle of the hopper matches the natural falling trend of the material to improve the collection efficiency.

[0038] Usually, the angle of the hopper is designed to be between 30° and 45°, which can ensure that the material slides into the hopper smoothly during transportation and prevent dust from spreading or overflowing due to improper angles. The structural material of the hopper is usually wear-resistant steel plate to cope with long-term use and the abrasive effect of dust, ensuring its durability and stability.

[0039] The dust waste material guide pipe 4 is connected to a plurality of dust waste material recovery hoppers 3 and is used to transport the dust waste to the dust waste recovery storage tank 5 ; the diameter of the dust waste material guide pipe 4 is determined according to the spatial structure of the first conveyor belt 1 and the second conveyor belt 2 .

[0040] Specifically, the dust waste guide pipe 4 is an important pipeline for connecting multiple dust waste recovery hoppers 3 and transporting the collected dust waste to the dust waste recovery storage tank 5. The design of the guide pipe ensures that the dust waste collected from multiple hoppers can be smoothly transported to the storage tank through the pipeline to avoid dust leakage or blockage during transportation. The diameter of the dust waste guide pipe 4 is determined according to the spatial structure of the first conveyor belt 1 and the second conveyor belt 2 to ensure that the guide pipe can be effectively installed in the system and maintain a stable connection with each conveyor belt. The diameter of the guide pipe is usually matched with the discharge capacity, dust volume, and length and spatial configuration of the conveying path of the conveyor belt, which not only ensures that the pipeline has sufficient capacity to transport dust waste, but also ensures that it can adapt to the complex spatial structure layout in the system. The guide pipe is usually made of wear-resistant materials to cope with the long-term impact and friction of dust particles and ensure the stable operation of the system.

[0041] The dust waste recovery storage tank 5 is installed on one side of the support frame and is used to store the recovered dust waste; the material of the dust waste recovery storage tank 5 includes but is not limited to carbon steel or stainless steel. The volume range of the dust waste recovery storage tank 5 is 500L-2000L.

[0042] Specifically, the design of the storage tank ensures that the recovered dust can be stored safely and orderly to prevent dust from spreading or polluting the environment. The material selection of the dust waste recovery storage tank 5 includes but is not limited to carbon steel or stainless steel. These materials have good corrosion resistance and wear resistance, can adapt to the long-term use requirements in the production process, and ensure that their strength is sufficient to withstand the pressure and weight of large volumes of dust. According to different production needs and the amount of recycled dust, the volume design range of the dust waste recovery storage tank 5 is generally 500 liters to 2000 liters, ensuring that the storage tank can provide sufficient storage space during peak production periods, avoiding the need for frequent cleaning and replacement of storage tanks. The connection between the tank body and the guide pipe adopts a sealed design to prevent dust leakage and ensure the safety and efficiency of the entire system.

[0043] The baffle plate 6 is installed at the bottom of the dust waste recovery storage tank 5 to control the discharge of the dust waste. The baffle plate 6 is designed according to the weight of the dust waste and has a thickness ranging from 5mm to 10mm.

[0044] Specifically, the baffle plate 6 can effectively manage the outflow of dust waste through reasonable design, ensure that the dust can be discharged smoothly when it is needed, and provide sealing when it is not needed to prevent dust leakage. According to the weight of the stored dust waste, the thickness of the baffle plate 6 is designed to be between 5 mm and 10 mm to ensure that it has sufficient strength and durability to withstand the pressure generated by the accumulation of dust in the tank. At the same time, the operation of the baffle plate 6 can be completed manually or through an automatic control system, and the specific choice depends on the degree of automation of the production system. The connection between the baffle plate 6 and the storage tank is made of wear-resistant and sealing materials to ensure that there will be no wear or leakage due to frequent opening and closing during operation, further ensuring the safety and efficient operation of the entire dust removal system.

[0045] Embodiment 2:

[0046] Please see attached Figure 2 The embodiment of the present invention provides a dust removal method for a dry production system of building aggregates, comprising the following steps:

[0047] S1. A dust waste recovery device is installed at the conveyor belt transfer position of the aggregate dry production system;

[0048] S2, collecting dust waste generated during aggregate transportation through the dust waste recovery hopper 3;

[0049] S3, transporting the dust waste to the dust waste recovery storage tank 5 through the dust waste guide pipe 4;

[0050] S4, regularly cleaning the dust waste in the dust waste recovery storage tank 5;

[0051] S5, the recovered dust waste is led out from the dust waste recovery storage tank 5 for unified treatment.

[0052] Specifically, in the dust removal process of the aggregate dry production system, it is first necessary to reasonably set up a dust waste recovery device at the transfer position of the conveyor belt. The device is installed on a support frame and is used to collect and process the dust waste generated during the production process. The core component of the recovery device is the dust waste recovery hopper 3, which is designed from a scientific perspective and can effectively collect the dust waste scattered from the conveyor belt. After the dust is collected in the hopper, the dust waste guide pipe 4 will transfer the dust waste to the dust waste recovery storage tank 5 for storage. The size and length of the dust waste guide pipe are reasonably configured according to the layout and spatial structure of the conveyor belt to ensure the smoothness of dust transportation. In order to ensure the normal operation of the system, the dust waste recovery storage tank 5 is cleaned regularly to avoid excessive accumulation of dust in the storage tank, which affects the capacity of the storage tank and the operating efficiency of the system. When the dust waste in the storage tank reaches the processing capacity, the dust waste needs to be guided out of the dust waste recovery storage tank 5 through the baffle plate 6 at the bottom, and uniformly processed or recycled. This process ensures the efficient operation of the entire dust removal system through reasonable device design and scientific management, prevents dust leakage and pollution, improves the cleanliness of the production environment, and ensures that dust waste is properly handled or reused.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
