Description

Technical Field

[0001] This utility model belongs to the technical field of sand making machine and shaping machine, specifically relating to an integrated sand making and shaping machine that combines sand making and shaping. Background Technology

[0002] A sand and gravel aggregate and manufactured sand production line generally consists of feeding equipment, primary crushing equipment, secondary crushing equipment, tertiary crushing equipment, aggregate shaping equipment, sand making equipment, sand shaping equipment, various screening equipment, sand washing equipment, fine sand dewatering and recycling equipment, sludge dewatering equipment, etc. To produce high-standard sand and gravel aggregates and manufactured sand, aggregate and sand shaping machines are essential equipment.

[0003] The typical feeding method for sand making machines is to feed material from the center of the distributor impeller through the feed hopper onto the distribution cone below the distributor impeller, and then use centrifugal force to scatter it onto the impact liners around the crusher cylinder, where the material is crushed through high-speed "stone-on-iron" impacts. At the same time, the sand-making raw material reflected from the impact liners is also crushed by "stone-on-stone" impacts with the material emitted by the distributor impeller in the crushing chamber.

[0004] Shaping machines typically employ two feeding methods during operation: a central feed and a surrounding waterfall feed. By adjusting the ratio of central feed to surrounding waterfall feed, high-grade sand can be produced. While shaping machines are generally designed for general use, the diverse types of raw materials required for sand production necessitate different performance requirements. For example, when producing manufactured sand from hard rock materials such as pebbles, granite, and andesite, a higher proportion of central feed and a lower proportion of surrounding waterfall feed are needed to produce high-grade sand. Conversely, when producing manufactured sand from soft rock materials such as limestone, a lower proportion of central feed and a higher proportion of surrounding waterfall feed are required to prevent over-crushing and unsatisfactory shaping results.

[0005] Due to the different raw materials used in sand making, the particle shape of the sand produced by impact crushing is difficult to meet the requirements of high-standard, high-specification manufactured sand. The roundness of the sand is poor, and it needs to be shaped. If the sand with poor particle shape produced by impact crushing is then shaped by a shaping machine via a belt conveyor, it will not only increase the space occupied but also increase the investment cost. Summary of the Invention

[0006] Therefore, this utility model designs a new type of integrated sand making and shaping machine, which integrates sand making and shaping functions together. Through integrated structural design, the upper crushing chamber of the machine can crush iron and make sand, while the lower shaping chamber can crush stone and shape it, thus achieving "one machine for multiple uses". This reduces the machine's site occupation and lowers the equipment's infrastructure installation, investment, and operating costs.

[0007] The objective of this utility model is achieved through the following means:

[0008] A novel integrated sand making and shaping machine includes a crushing chamber, an integrated rotor inside the crushing chamber, a sand making impeller on the upper part of the integrated rotor, a sand making impact crushing plate on the inner wall of the crushing chamber corresponding to the sand making impeller, a screen plate chute cone at the bottom of the sand making impact crushing plate, and a shaping impeller at the lower part of the integrated rotor. The bottom outlet of the screen plate chute cone corresponds to the shaping impeller. The diameter of the sand making impeller is smaller than the diameter of the shaping impeller. The inner wall of the crushing chamber corresponding to the shaping impeller forms a stone-on-stone lining structure, and the bottom of the inner wall of the crushing chamber corresponding to the shaping impeller is provided with a stone-on-stone rib structure.

[0009] The aforementioned new type of integrated sand making and shaping machine has a conical stone-on-stone reinforcement plate structure, which, together with the stone-on-stone lining structure, forms a stone-on-stone impact structure.

[0010] In the aforementioned novel integrated sand making and shaping machine, the sand making impact crusher plate is a sawtooth-shaped crusher plate.

[0011] The aforementioned new type of integrated sand making and shaping machine has a material distribution cone installed at the lower part of the feed inlet of the crushing chamber, which corresponds to the sand making impeller.

[0012] The aforementioned new type of integrated sand making and shaping machine has a feed hopper at the top of the crushing chamber and a distribution cone at the bottom of the feed hopper, which corresponds to the sand making impeller.

[0013] Compared with the prior art, the present invention has the following technical effects:

[0014] This invention integrates sand making and shaping functions. The upper sand making impeller and impact crusher form a stone-on-iron structure. Material ejected from the sand making impeller interacts with the impact crusher for sand making. Larger materials passing through the screen plate chute cone enter the lower shaping impeller, while smaller materials fall directly from the screen plate. The stone-on-stone impact structure forms a lining layer. The smaller materials below the screen plate of the chute cone interact with the material ejected from the shaping impeller for stone-on-stone shaping. Simultaneously, the material ejected from the shaping impeller interacts with the material on the lining layer for stone-on-stone shaping. This integrated structural design allows for both stone-on-iron sand making in the upper crushing chamber and stone-on-stone shaping in the lower shaping chamber, achieving "one machine for multiple uses," reducing machine footprint and lowering equipment installation, investment, and operating costs.

[0021] The following is in conjunction with the appendix Figures 1-2 The structure and working process of this utility model will be described in detail.

[0022] A novel integrated sand making and shaping machine includes a crushing chamber, which is an extended and deep cavity structure. An integrated rotor 7 is installed inside the crushing chamber. The upper part of the crushing chamber is designed according to the structure of a sand making machine. A sand making impeller 2 is installed on the upper part of the integrated rotor. A sand making impact crushing plate 3 is installed on the inner wall of the crushing chamber corresponding to the sand making impeller. The impeller adopts a stone-on-iron structure. The diameter of the sand making impeller is designed according to the structural dimensions of a normal sand making machine. Impact lining plates are installed around the crushing chamber. The high-speed rotating impeller throws the sand making raw material at high speed onto the impact crushing plate with a serrated structure around the crushing chamber, thereby realizing machine sand making. A screen plate feed cone 4 is installed at the bottom of the sand-making impact crusher plate. Below the crushing chamber, a stone-on-stone structure is designed according to the structure of a shaping machine. That is, a shaping impeller 5 is installed at the bottom of the integrated rotor. The diameter of the shaping impeller is designed according to the normal structural dimensions of the shaping machine. The bottom discharge port of the screen plate feed cone corresponds to the shaping impeller. The diameter of the sand-making impeller is smaller than that of the shaping impeller. The inner wall of the crushing chamber corresponding to the shaping impeller forms a stone-on-stone lining structure. A stone-on-stone rib structure 8 is installed at the bottom of the inner wall of the crushing chamber corresponding to the shaping impeller. The sand-making machine impeller has a small diameter, resulting in a large impact force on the ejected material. The shaping machine impeller has a large diameter, resulting in a small impact force on the ejected material. A material lining pad mechanism that easily forms a material lining layer is set around the crushing chamber, i.e., a stone-on-stone impact structure. This allows the shaping impeller to throw the sand-making raw material at high speed onto the material lining layer around the crushing chamber, achieving stone-on-stone shaping. Simultaneously, the raw material for sand making descends in a waterfall-like manner from the screen plate chute cone, where it is shaped by stone-on-stone impact with the material thrown out from the shaping impeller. The sand making impeller and the shaping impeller are mounted on an integrated rotor shaft and rotate at high speed driven by the motor pulley 6. In the upper crushing chamber, high-speed stone-on-iron impact is used to make sand, while in the lower shaping chamber, low-impact, short-distance stone-on-stone impact is used to shape the sand.

[0023] The novel integrated sand making and shaping machine of this utility model has a conical stone-on-stone reinforcement plate structure, which is combined with the stone-on-stone lining structure to form a stone-on-stone impact structure.

[0024] The novel integrated sand making and shaping machine of this utility model has a sawtooth-shaped impact crusher plate.

[0025] The novel integrated sand making and shaping machine of this utility model has a feeding hopper 9 at the top of the crushing chamber and a feeding cone 1 at the bottom of the feeding hopper, which corresponds to the sand making impeller.

[0026] The material distribution cone 1 of this utility model is a material distribution mechanism installed on the sand making impeller on the upper part of the integrated machine rotor. The sand making raw material entering from the center of the sand making impeller is evenly thrown into the crushing chamber at high speed along the flow channel plate of the sand making impeller through the conical structure of the material distribution cone.

[0027] The sand-making impeller 2 of this invention is a high-speed material ejection mechanism that can rotate on the upper part of the integrated rotor. The sand-making impeller 2 is installed on the upper part of the main shaft of the integrated rotor 7 and rotates with the high-speed rotation of the main shaft. Thus, the material entering the impeller's feeding cone 1 is thrown into the crushing chamber through the discharge port.

[0028] The sand-making impact crusher plate 3 of this utility model is an impact crushing mechanism with a serrated structure installed around the crushing chamber on the upper part of the rotor of an integrated machine. It is installed around the crushing chamber via a stone-on-iron impact plate structure. The sand-making impact crusher plate 3 can be easily replaced after wear and failure. It is generally made of high-wear-resistant high-chromium cast iron or hypereutectic high-chromium cast iron.

[0029] The screen plate conveyor cone 4 of this utility model is a sand-making material receiving conveyor and screening plate installed below the upper crushing chamber of the integrated machine. Part of the material falling from the upper crushing chamber falls into the shaping chamber through the mesh on the screen plate conveyor cone 4, realizing waterfall discharge; the other part enters the shaping impeller 5 along the cone conveyor and is thrown into the shaping chamber along the flow channel plate.

[0030] The shaping impeller 5 of this invention is a rotatable material ejection mechanism installed on the integrated rotor 7. The shaping impeller 5 is mounted in the middle of the main shaft of the integrated rotor 7 and rotates with the high-speed rotation of the main shaft. This causes the material entering the impeller to be ejected through the discharge port into the shaping chamber.

[0031] The motor pulley 6 of this utility model is a power transmission device installed at the lower part of the integrated machine rotor 7. It is driven to rotate at high speed by a frequency-controlled motor and a triangular transmission belt, thereby driving the sand-making impeller 2 and the shaping impeller 5 to rotate at high speed to realize sand making and shaping operations.

[0032] The integrated rotor 7 of this utility model is the core component of the integrated machine. Its upper and lower ends are supported by bearings and rotate at high speed under the drive of the rotor pulley, thereby driving the sand-making impeller 2 and the shaping impeller 5 to rotate at high speed.

[0033] The stone-on-stone material lining and rib structure of this utility model is a material lining forming structure arranged around the lower forming cavity of the integrated machine, which facilitates the formation of a material lining layer. The material thrown out from the forming impeller 5 first enters the ribs that form and fix the material lining layer, forming a material lining layer of a certain thickness, thereby achieving stone-on-stone operation with the material thrown out from the forming impeller 5.

[0034] The stone-on-iron impact plate structure of this utility model is a suspension structure of fixed sand-making impact crushing plates 3 arranged around the crushing chamber of the integrated machine. The impact crushing plates 3 are arranged around the crushing chamber of the integrated machine to achieve stone-on-iron operation with the material thrown out by the sand-making impeller 2.

[0035] The feed hopper 9 of this utility model is the material feeding mechanism at the top of the integrated machine. Through it, the raw materials for sand making can enter the sand making impeller 2, thereby realizing the sand making operation.

[0036] 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.
