Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand making equipment technology, and in particular to a high-efficiency, energy-saving, high-flow shaping sand making machine. Background Technology
[0002] With societal development, the demand for energy across all industries is increasing, including mining. However, many high-energy-consuming and low-output equipment are no longer suitable for current development and are gradually facing obsolescence. Shaping and crushing sand making machines are suitable for crushing massive amounts of materials in industries such as metallurgy and mining. The current maximum flow shaping and crushing sand making machines typically have a production efficiency of 400-500 t / h, with a single machine having a power consumption of 630 kW. When facing the mainstream 600-800 t / h sand production line, one machine clearly cannot meet the demand. Two machines would require 1260 kW of power, effectively doubling the reactive power, leading to overcapacity and increased floor space. Therefore, it is necessary to develop a high-flow, low-energy-consumption sand making machine to solve the current problems of insufficient flow, high power consumption, and large floor space requirements.

[0013] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.
[0014] See Figure 1 This embodiment provides a high-efficiency, energy-saving, high-flow shaping and sand making machine, including: a machine casing body 2, an upper cover 1, a base 3, a cover opening device 4, an impeller 5, a bearing cylinder 6, and a motor 7.
[0015] The casing body 2 is fixed to the base 3 by welding. A crushing chamber is formed inside the casing body 2. An impeller 5 is installed inside the crushing chamber. The diameter of the impeller 5 is greater than 1000mm, and the internal space dimensions of the crushing chamber are designed accordingly based on the size of the impeller. In this embodiment, the diameter of the impeller 5 is preferably set to 1050mm. The lower end of the impeller 5 is connected to the bearing sleeve 6 through a shrink sleeve 8. The bearing sleeve 6 is bolted and fixed to the center position of the internal frame of the crushing chamber. The crushing chamber is also provided with multiple material impact structures, such as impact plates, which are fixedly installed inside the crushing chamber by bolts. After the material enters the crushing chamber, it is rapidly accelerated inside the impeller and then ejected from the impeller's flow channel, colliding with the material impact structures. The material impact structures bounce off and are then impacted again. In this way, large pieces of material are crushed into fine particles after being subjected to two or more impacts, friction, and grinding in the crushing chamber.
[0016] Preferably, the upper end of the casing body 2 is provided with a feed hopper structure 21, which facilitates feeding and also makes it easy to inspect and repair the vulnerable parts inside the impeller 5.
[0017] A top cover 1 is installed on the upper end of the housing body 2. A cover opening device 4 is also provided on the side of the top cover 1. The cover opening device 4 uses a cantilever crane, and the column of the cantilever crane is welded and fixed to one side of the housing body 2. The top cover 1 is provided with a lifting structure for cooperating with the cantilever crane. One side of the top cover 1 is hinged to the housing body 2 (e.g., Figure 1 As shown in Figure 11, it can rotate about the hinge center. See also... Figure 2 The diagram illustrates the open state of the upper cover 1, which is lifted and rotated open by a cantilever crane. Once the upper cover 1 is opened via the opening device, it facilitates equipment maintenance and parts replacement.
[0018] Two drive motors 7 are installed on the base 3 and are fixed to the base 3 by bolts. The drive motors 7 are the components that provide driving force for the shaping and sand making machine. The drive motors 7 are connected to an external power source to operate.
[0019] The high-efficiency, energy-saving, high-flow shaping and crushing sand making machine of this embodiment has a total power of 800KW per unit. It features an impeller of a specific size, which, compared to existing shaping and crushing sand making machines, increases the material passage space and the crushing ratio, meeting the power requirements of mainstream sand making production lines. All transmission components meet the mechanical performance requirements under high-flow conditions. Through these optimizations, the material throughput reaches 600-800t / h, power increases by 20%, and flow rate increases by approximately 35%. The original requirement of two machines to meet the production line's needs is reduced to that of a single high-flow shaping and crushing sand making machine, thus achieving the design goals of energy efficiency, high performance, and small footprint.
[0020] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
