Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel aggregate production, and in particular to a modular sand and gravel aggregate rapid production system. Background Art

[0002] Sand and gravel aggregate crushing and screening is the production process of reducing stones from large to small. The finished materials can only be obtained after multi-stage crushing by crusher and screening by screening machine. The traditional production line needs a long time from the initial design stage to the finished product stage, which greatly affects the rate of return on investment. In the past, traditional sand and gravel aggregate production lines had high transportation costs and large on-site preparation work. Due to the large size and complex structure of the product itself, the installation process is more difficult, the debugging cycle after installation is long, the production is slow, the production efficiency is low, and the rate of return on investment is low. For the problems existing in traditional sand and gravel aggregate production lines, if the modular layout planning of crushing and screening can be carried out in advance to maximize the delivery and rapid assembly needs, improve transportation convenience and simplicity of installation, it will greatly reduce the customer's cost of use.

[0003] Therefore, based on the application experience of fixed and mobile production lines, combined with the technical accumulation of on-site production line construction and installation, a highly convenient modular combination rapid production line was launched to achieve rapid delivery, rapid assembly, and rapid debugging to the greatest extent. Summary of the invention

[0004] In view of the above problems, the present invention is proposed to provide a modular sand and gravel aggregate rapid production system that overcomes the above problems or at least partially solves the above problems, which can solve the problems existing in the traditional sand and gravel aggregate production line, achieve modular layout planning of crushing and screening equipment, and thus improve the convenience of equipment use.

[0005] Specifically, the present invention provides a modular sand and gravel aggregate rapid production system. It includes multiple modular production lines, each of which is composed of multiple modular stations, each of which includes a crushing module, an MP module transfer, an MP module screening and an electric control module; Among them, the crushing module performs multi-stage crushing on the material, the MP module transfers the material crushed by the crushing module to the MP module for screening, the MP module screening processes the material, and the electronic control module controls the start and stop actions of the crushing module, MP module transfer and MP module screening.

[0006] By modularizing the production line, a production line is composed of multiple groups of module stations. Each group of module stations includes a crushing module, MP module transfer, MP module screening and electronic control module. The modules in the conventional production line are replaced by MP modular stations, and each module is simplified and standardized to facilitate shipment, transportation and on-site installation and commissioning. According to the production capacity of the crushing module, it can be combined into a variety of standard production lines. It can also be freely combined according to the user's own needs, and the layout and planning of personalized production lines can be realized to achieve rapid investment returns.

[0007] The crushing module performs multi-stage crushing on the material to ensure the adequacy of the crushing processing of the material and the crushing parameter requirements of the material of different specifications. The MP module transfers the crushed material from the crushing module to the MP module for screening. The MP module screens the material to meet the crushing standards of the material. The electronic control module controls the start and stop actions of the crushing module, MP module transfer and MP module screening. Multiple MP modular stations are integrated with belt conveyors and electronic control modules to realize fully automated sand and gravel aggregate production. Optionally, the crushing module comprises: MP modular coarse crushing station and MP modular medium and fine crushing station. The MP modular coarse crushing station performs primary crushing treatment on the materials. The processed materials are transferred to the MP modular medium and fine crushing station through the MP module. The MP modular medium and fine crushing station performs secondary or tertiary crushing treatment on the materials.

[0008] By setting up the MP modular coarse crushing station to carry out primary crushing of materials, the materials can be crushed from the original larger size to a smaller size, so as to facilitate the subsequent MP modular medium and medium crushing station to carry out secondary or tertiary crushing of the materials, so that the materials can meet the process requirements. Optionally, the MP module transfer includes: A belt conveyor for conveying materials, a transfer buffer silo and a raw material silo for storing materials, the belt conveyor includes a coarse material belt conveyor connected between the MP modular coarse crushing station and the MP modular medium and fine crushing station, the coarse material belt conveyor conveys the coarsely crushed materials to the MP modular medium and fine crushing station, and the transfer buffer silo is arranged in the middle of the coarse material belt conveyor to cache the coarsely crushed materials of the MP modular coarse crushing station, so that the materials slowly enter the MP modular medium and fine crushing station.

[0009] The crushed materials are transported by belt conveyors. In order to ensure the stability of the belt conveyors in transporting materials, the belts are all arc-shaped belts so that the materials can be concentrated at the arc-shaped bottom of the belts, thereby preventing the materials from falling from the belt conveyors.

[0010] The coarse material belt conveyor between the MP modular coarse crushing station and the MP modular medium and fine crushing station is used to transport the coarsely crushed materials to the MP modular medium and fine crushing station. In order to improve the adequacy of the fine processing of materials by the MP modular medium and fine crushing station, it is necessary to avoid the accumulation of materials at the MP modular medium and fine crushing station. The transfer buffer silo is arranged in the middle of the coarse material belt conveyor to cache the coarsely crushed materials of the MP modular coarse crushing station, thereby reducing the speed of the materials flowing into the MP modular medium and fine crushing station, so that the materials in the MP modular medium and fine crushing station can be fully crushed and the effect of the fine crushing is guaranteed.

[0011] By using the MP modular coarse crushing station and the MP modular medium and fine crushing station to crush materials, the processed materials can cover hard rocks with a saturated ultimate compressive strength Rb greater than 30MPa and soft rocks with a saturated ultimate compressive strength Rb less than 30Mpa, meeting the crushing needs of a variety of materials.

[0012] The standard transfer buffer silo can provide stable material supply to the crusher, realize continuous production, and provide conditions for improving production efficiency. Optionally, the MP modular coarse crushing station includes a jaw crusher, and a screening belt conveyor is provided at the bottom of the jaw crusher. The screening belt conveyor discharges unqualified materials after crushing by the jaw crusher, collects them and then enters the jaw crusher for coarse crushing for a second time.

[0013] The jaw crusher is used to carry out preliminary crushing of sand and gravel aggregates, so that larger materials can be crushed into the process requirements of the MP modular medium and medium crushing station, thereby ensuring the stability of subsequent sand and gravel aggregate processing. A screening belt conveyor is also provided at the bottom of the jaw crusher to discharge unqualified, larger materials after crushing by the jaw crusher to avoid flowing into the MP modular medium and medium crushing station, resulting in the inability to complete the fine crushing process. The larger materials after screening will be put back into the MP modular coarse crushing station for re-crushing. Optionally, the MP module screening comprises, Screening frame, the belt conveyor also includes a medium-fine material belt conveyor connected between the MP modular medium-fine crushing station and the input end of the screening frame, and multiple screening layers are arranged in the screening frame, and a screening belt conveyor is arranged on each screening layer to transport the material in the screening layer to the silo; The belt conveyor also includes a re-crushing belt conveyor connected between the screening frame and the input end of the transfer buffer silo to send the insufficiently crushed materials to the MP modular medium and fine crushing station for crushing again; MP modular secondary and tertiary crushing station is a cone crusher.

[0014] The materials crushed by the MP modular medium and fine crushing station are transported to the input end of the screening frame through the medium and fine material belt conveyor. The materials crushed by the fine crushing station are screened by the multi-layer screening layers in the screening frame. According to different process requirements, materials of different specifications are collected, and the screening belt conveyors set on each screening layer are used to transport the materials to the silo for collection and processing.

[0015] Through the re-crushing belt conveyor between the screening frame and the input end of the transfer buffer silo, the materials that do not meet the process requirements during fine crushing are re-conveyed to the transfer buffer silo, and the materials are re-sent to the MP modular fine crushing station for crushing, thereby ensuring the adequacy of material processing. Optionally, the MP modular coarse crushing station, the MP modular medium and fine crushing station, the transfer buffer silo and the screening frame are all equipped with a sled-type support base to avoid fixing with anchor bolts.

[0016] By equipping the MP modular coarse crushing station, MP modular medium and fine crushing station, transfer buffer silo and screening frame with a sled-type support base, it can ensure the support stability while facilitating the transportation and installation of the equipment. It also eliminates the need for anchor bolts to reduce damage to the workshop floor during installation. Optionally, the coarse material belt conveyor, medium and fine material belt conveyor and complex crushing belt conveyor are all provided with a sled-type support base at the bottom, and the support base is also provided with a V-shaped bracket to support the coarse material belt conveyor, medium and fine material belt conveyor and complex crushing belt conveyor at different inclination angles.

[0017] By supporting the bottom of the coarse material belt conveyor, medium and fine material belt conveyor and complex crushing belt conveyor with a sled-type support base, the supporting stability of the support base can be improved, and the occupied ground area when supporting the belt conveyor can be reduced. By also providing a V-shaped bracket on the support base, the downward pressure of the belt conveyor can be concentrated on the support base, thereby improving the supporting stability of the belt conveyor by the support base. It can also support the coarse material belt conveyor, medium and fine material belt conveyor and complex crushing belt conveyor at different inclination angles to meet the use requirements of the belt conveyor. Optionally, two groups of bracket compartments are symmetrically arranged in the support base, and the two groups of bracket compartments are each equipped with a bracket base. The V-shaped bracket is composed of two groups of trapezoidal brackets that are V-shaped and respectively connected at both ends of the bracket base, and the spacing between the two groups of bracket bases is greater than the width of the belt conveyor.

[0018] By arranging two groups of trapezoidal brackets connected to the bracket base in a V shape at both ends of the bracket base, the supporting stability of the V-shaped bracket can be improved, and the trapezoidal bracket can better match the size difference between the bracket base and the belt conveyor, thereby further stabilizing the supporting stability of the V-shaped bracket for the belt conveyor. By making the spacing between the two groups of bracket bases larger than the width of the belt conveyor, the supporting stability of the bracket base for the belt conveyor can be improved. Optionally, the crushing module, MP module transfer and MP module screening are arranged in a rotary manner to reduce the space occupancy rate of the crushing module, MP module transfer and MP module screening during the layout process.

[0019] The crushing module, MP module transfer and MP module screening are arranged in a rotary manner. Through the free combination of MP modules, users can freely combine personalized production lines, and can also be used to upgrade and expand existing old production lines. In this way, the use of MP modules has a high degree of freedom. The MP modular station can be used to replace each module on the production line without multiple designs, or only a small amount of changes can be made to meet the needs. Optionally, the crushing module, MP module transfer and MP module screening all adopt a pure steel structure design style to facilitate transportation and installation.

[0020] By adopting pure steel structure design style for all modular products, all products meet the requirements of container transportation, which can not only meet the needs of rapid installation on site, but also meet the needs of later transfer and the value-added benefits of steel structure, achieving the goals of rapid installation, rapid production and rapid profits. In the technical solution of the present invention, the production line is modularized and a production line is composed of multiple groups of module stations. Each group of module stations includes a crushing module, an MP module transfer, an MP module screening and an electronic control module. Each module in the conventional production line is replaced by an MP modular station, and each module is simplified and standardized to facilitate shipment, transportation and on-site installation and commissioning. A variety of standard production lines can be combined according to the production capacity of the crushing module. Standard modules can also be freely combined according to the user's own needs to layout and plan personalized production lines to achieve rapid investment returns.

[0021] Furthermore, in the technical solution of the present invention, the crushing module, MP module transfer and MP module screening are arranged in a rotary manner. Through the free matching of MP modules, users can freely combine personalized production lines, and can also use them to upgrade and expand existing old production lines. In this way, the MP modules have a high degree of freedom in use.
